现有技术中，皮带机托辊辊体的装配工序一般为：滚皮下料制成辊皮坯料→辊皮坯料镗孔加工成辊皮零件→滚皮零件与轴承座零件组装定位→焊接制作成辊体部件。在上述工序中，滚皮切割下料制成辊皮坯料后，还要在镗床上镗削两端的轴承座安装孔，合格后，再将轴承座装配到辊皮两端镗好的安装孔内，为了便于装配，辊皮两端的安装孔的内径常常比轴承座端部的安装盘的外径更大，使轴承座端部的安装盘与辊皮两端的安装孔之间形成间隙配合，于是，为了保证辊体在工作中辊皮不会相对于轴承座转动，就必须将辊皮与轴承座的安装盘焊接在一起。所以整个辊体的装配制作工艺的工序较多、工艺复杂、工艺设备也较多，使生产效率无法提高，从而增加了生产成本。In the prior art, the assembly process of the idler roller body of the belt conveyor is generally as follows: roll skin blanking to make a roll skin blank → roll skin blank boring and processing into a roll skin part → assembly and positioning of the roll skin part and bearing seat parts → welding to make a Roller parts. In the above process, after the roll skin is cut and blanked to make the roll skin blank, the bearing seat mounting holes at both ends must be bored on the boring machine. After passing the test, the bearing seat is assembled into the bored mounting holes at both ends of the roll skin , in order to facilitate assembly, the inner diameter of the mounting holes at both ends of the roller skin is often larger than the outer diameter of the mounting plate at the end of the bearing seat, so that a clearance fit is formed between the mounting plate at the end of the bearing seat and the mounting holes at both ends of the roller skin, so , in order to ensure that the roller skin will not rotate relative to the bearing seat during the work of the roller body, the roller skin and the mounting plate of the bearing seat must be welded together. Therefore, the assembly and manufacturing process of the entire roller body has many procedures, complex processes, and many process equipments, so that the production efficiency cannot be improved, thereby increasing the production cost.

具体实施方式Detailed ways

如图1、图2所示是本发明提供的一种装配制作工序更简单、使用工艺设备更少、生产效率高的用于皮带机托辊辊体的装配制作方法。所述装配制作方法包括以下工艺步骤，As shown in Fig. 1 and Fig. 2, the assembling and manufacturing method for the idler roller body of the belt conveyor provided by the present invention has simpler assembling and manufacturing procedures, less process equipment and high production efficiency. The assembly manufacturing method includes the following process steps,

首先将滚皮下料制作成辊皮1；然后根据制作合格后的辊皮1端部的安装孔11尺寸，加工制作轴承座2，使所述轴承座2的安装盘21的外径大于辊皮1端部安装孔11的内径而具有装配过盈量；接着用外力将两个所述轴承座2同时分别压入辊皮1两端的安装孔11中，这样便完成了皮带机托辊辊体的加工制作，形成了辊体的辊皮1与轴承座2的安装盘21的过盈装配连接。像这样，通过将轴承座2的安装盘21的外径加工得比辊皮1两端的安装孔11的内径大，从而使轴承座2的安装盘21与辊皮1的安装孔11之间具有过盈装配量，然后再用外力将轴承座2压入上述辊皮1两端的安装孔11中，使轴承座2的安装盘21与辊皮1的安装孔11之间通过过盈装配连接，保证辊皮1不会相对于轴承座2转动，使装配结构牢固可靠，这样就可以省去在装配完成后将轴承座2焊接到辊皮1上的焊接工序以及焊后的矫正工序，使整个装配制作过程的工序更简单、使用工艺设备更少、生产效率能够得到很大提高。First, the roll skin is blanked to make aroll skin 1; then, according to the size of themounting hole 11 at the end of thequalified roll skin 1, thebearing seat 2 is processed so that the outer diameter of themounting plate 21 of thebearing seat 2 is larger than the roll skin. 1 The inner diameter of themounting hole 11 at the end has an assembly interference; then the two bearingseats 2 are pressed into themounting holes 11 at both ends of theroller skin 1 at the same time with an external force, thus completing the roller body of the belt conveyor roller The processing and manufacture of the roller body form the interference fit connection between theroller skin 1 of the roller body and themounting disc 21 of thebearing seat 2. Like this, by processing the outer diameter of themounting disc 21 of the bearinghousing 2 to be larger than the inner diameter of themounting holes 11 at both ends of theroll skin 1, there is a space between themounting disc 21 of the bearinghousing 2 and themounting hole 11 of theroll skin 1. The amount of interference fit, and then use external force to press thebearing seat 2 into themounting holes 11 at both ends of the above-mentionedroller skin 1, so that themounting plate 21 of thebearing seat 2 and themounting hole 11 of theroller skin 1 are connected through interference fit, Ensure that theroller skin 1 will not rotate relative to thebearing seat 2, so that the assembly structure is firm and reliable, so that the welding process of welding thebearing seat 2 to theroller skin 1 after assembly and the post-welding correction process can be omitted, so that the entire The process of assembly and manufacturing process is simpler, the use of process equipment is less, and the production efficiency can be greatly improved.

本发明中所述的滚皮，即为制作辊皮1的原材料，一般为无缝钢管，经切割下料后可以直接制作成辊皮1。如背景资料所述，现有技术中，当滚皮切割下料制成辊皮坯料后，还需要对辊皮坯料两端的安装孔进行加工才能使用，这样无形中将增加制作工序，同时也会增加工艺设备和装配制作周期。而实际上该加工工序的意义仅在于后序的装配方便，对整个辊皮的装配质量没有直接影响，而由于有了该道加工工序，反而还要增加工序、增加工艺设备，也就相应的降低了装配制作生效率，增加了生产成本，故为了进一步简化装配制作工序、减少加工设备和提高生产效率，本发明所述辊皮1由滚皮直接下料而成，其端部安装孔11的内径尺寸为滚皮现有的内孔尺寸，此时若出现所述安装孔11的椭圆度超标，则在后序可以通过轴承座2的安装盘21在压入的过程中进行矫正，进而达到提高效率的目的。The roll skin described in the present invention is the raw material for making theroll skin 1, which is generally a seamless steel pipe, which can be directly made into theroll skin 1 after cutting and blanking. As mentioned in the background information, in the prior art, after the roll skin is cut and blanked to make the roll skin blank, it is necessary to process the mounting holes at both ends of the roll skin blank before it can be used, which will increase the manufacturing process virtually, and will also Increase process equipment and assembly production cycle. In fact, the significance of this processing procedure is only for the convenience of subsequent assembly, and has no direct impact on the assembly quality of the entire roller skin. However, because of this processing procedure, it is necessary to increase the process and increase the process equipment, which is corresponding The production efficiency of assembly production is reduced, and the production cost is increased. Therefore, in order to further simplify the assembly production process, reduce processing equipment and improve production efficiency, theroll skin 1 of the present invention is formed by directly blanking the roll skin, and itsend mounting holes 11 The inner diameter size is the existing inner hole size of the roller skin. If the ellipticity of themounting hole 11 exceeds the standard at this time, it can be corrected in the process of pressing themounting plate 21 of thebearing seat 2 in the subsequent sequence, and then To achieve the purpose of improving efficiency.

上述实施方式中，在使用外力将轴承座2压入辊皮1两端的安装孔21中时，为了提高生产效率，降低操作人员的劳动强度，按下述步骤来进行，In the above-mentioned embodiment, when using external force to press the bearinghousing 2 into theinstallation holes 21 at both ends of theroll skin 1, in order to improve the production efficiency and reduce the labor intensity of the operator, the following steps are followed:

首先将现有装配模具3的上模31和下模32分别安装到压力机的上工作台和下工作台上，并使上模31的轴向工作中心与下模32的轴向工作中心位于同一条垂直线上；然后再将两个轴承座2按装配位置分别支撑到上模31和下模32上；接着将辊皮1沿垂直方向套入上模31和下模32上的轴承座2上，调整合格后，起动压力机通过上模31和下模32将上、下各一个轴承座2压入辊皮1两端的安装孔11中。像这样，采用现有装配模具3安装到压力机的同一条垂直中心线上后，再通过所述装配模具3将轴承座2压入辊皮1的安装孔11中的实施方式，既不需要重新制作模具，而节约装配成本，又可以使操作人员在装配过程中，只需进行一些简单操作，而大大降低操作人员的劳动强度。当然，使用外力将轴承座2压入辊皮1的操作，也可以是由操作人员使用二锤、榔头等手工工具人工进行，此时，操作人员的工作劳动强度就特别大。First, theupper mold 31 and thelower mold 32 of the existingassembly mold 3 are respectively installed on the upper workbench and the lower workbench of the press, and the axial work center of theupper mold 31 and the axial work center of thelower mold 32 are located on the same vertical line; then support the two bearinghousings 2 on theupper mold 31 and thelower mold 32 respectively according to the assembly position; then insert theroller skin 1 into the bearing housings on theupper mold 31 and thelower mold 32 in thevertical direction 2. After the adjustment is qualified, the starting press presses the upper andlower bearing blocks 2 into themounting holes 11 at the two ends of theroller skin 1 through theupper die 31 and thelower die 32. Like this, after theexisting assembly mold 3 is installed on the same vertical center line of the press, thebearing seat 2 is pressed into theinstallation hole 11 of theroll skin 1 through theassembly mold 3, and neither Remaking the mold saves the assembly cost and enables the operator to perform some simple operations during the assembly process, greatly reducing the labor intensity of the operator. Certainly, the operation of using external force to press thebearing seat 2 into theroll skin 1 can also be performed manually by the operator using hand tools such as hammers and hammers. At this time, the labor intensity of the operator is particularly large.

上述实施方式中，为了方便轴承座2在上模31和下模32上的定位和支撑，所述装配模具3的上模31和下模32上分别设置有与轴承座2的内孔相匹配的上导向模块311和下导向模块321，所述上导向模块311和下导向模块321同轴。这样，操作人员在将轴承座2安装到上模31和下模32上时，只需将所述轴承座2套到上导向模块311和下导向模块321上，由上导向模块311和下导向模块321自动对轴承座2进行定位并保证上、下两个轴承座同轴，操作十分便，同时也能提高位于辊皮1两端安装孔11内的轴承座2的同轴度。In the above embodiment, in order to facilitate the positioning and support of thebearing seat 2 on theupper mold 31 and thelower mold 32, theupper mold 31 and thelower mold 32 of theassembly mold 3 are respectively provided with Theupper guide module 311 and thelower guide module 321, theupper guide module 311 and thelower guide module 321 are coaxial. In this way, when the operator installs thebearing seat 2 on theupper mold 31 and thelower mold 32, he only needs to put thebearing seat 2 on theupper guide module 311 and thelower guide module 321, and theupper guide module 311 and the lower guide module Themodule 321 automatically positions thebearing seat 2 and ensures that the upper and lower bearing seats are coaxial, which is very convenient to operate, and can also improve the coaxiality of thebearing seat 2 located in themounting holes 11 at both ends of theroller skin 1.

由图1装配合格的辊体部件以及图2的装配过程示意图可知，在使用外力将轴承座2压入辊皮1两端的安装孔11中时，上模31和下模32均要承受辊皮1的压力和摩擦力，上导向模块311和下导向模块321由于与轴承座2之间有摩擦，也将承受摩擦力，为了保证在装配过程中，不会由于外力的作用而将所述装配模具3压裂，同时又能提高装配模具3的耐磨性，所述装配模具3由45#钢制成，其工作表面还经调质处理。It can be seen from the assembled roller body components in Figure 1 and the schematic diagram of the assembly process in Figure 2 that when thebearing seat 2 is pressed into themounting holes 11 at both ends of theroll skin 1 by external force, both theupper die 31 and thelower die 32 must bear the pressure of the roll skin. 1 pressure and friction force, theupper guide module 311 and thelower guide module 321 will also bear the friction force due to the friction between them and thebearing seat 2, in order to ensure that the assembly process will not be damaged due to the action of external force Themold 3 is fractured, and at the same time, the wear resistance of theassembly mold 3 can be improved. Theassembly mold 3 is made of 45# steel, and its working surface is also subjected to quenching and tempering treatment.
