技术领域technical field
本发明涉及复合材料布带缠绕技术领域，具体是一种复合材料布带自适应缠绕机构。The invention relates to the technical field of composite material cloth tape winding, in particular to a composite material cloth tape self-adaptive winding mechanism.
背景技术Background technique
复合材料，因其比强度高、比模量大、耐腐蚀、减震性好等优点，在现代材料领域所占比重越来越大。布带缠绕是制造高强度复合材料构件的一种重要方法。Composite materials, because of their advantages such as high specific strength, large specific modulus, corrosion resistance, and good shock absorption, account for an increasing proportion in the field of modern materials. Tape winding is an important method for manufacturing high-strength composite components.
数控布带缠绕机是采用碳/酚醛、高硅氧/酚醛等预浸胶带缠绕固体火箭发动机喷管零部件的专用设备。该机在缠绕时对布带施加恒定的张力，在缠绕点附近使布带加热，通过恒定的压力将布带滚压在成型模胎上，缠绕后再将零件固化成型。The CNC tape winding machine is a special equipment for winding solid rocket motor nozzle parts with carbon/phenolic, high silica/phenolic and other prepreg tapes. The machine applies constant tension to the cloth tape during winding, heats the cloth tape near the winding point, rolls the cloth tape on the molding tire with constant pressure, and solidifies the part after winding.
目前的缠绕机构一般是将热压滚轮固定，并将热压滚轮轴线与缠绕零件的轴线平行，缠绕时由气缸推动热压滚轮，使之贴合在缠绕零件的型面上。布带绕过热压滚轮后贴在缠绕零件上，当主轴带动缠绕零件转动后，布带便可缠绕在零件的表面上。当面对锥形模胎缠绕过程时，由于布带在锥形模胎缠绕的厚度不均匀，导致热压滚轮不能很好的贴合缠绕型面，这将使缠绕零件的密度不均匀，力学性能下降。因此亟需一种能在缠绕零件过程中能自适应于成型模胎表面的热压机构。The current winding mechanism generally fixes the hot pressing roller, and makes the axis of the hot pressing roller parallel to the axis of the winding part. The cloth tape goes around the hot pressing roller and sticks on the winding part. When the main shaft drives the winding part to rotate, the cloth tape can be wound on the surface of the part. When facing the tapered mold tire winding process, due to the uneven thickness of the cloth tape wound on the tapered mold tire, the hot pressing roller cannot fit the winding surface well, which will make the density of the winding parts uneven, and the mechanics Performance drops. Therefore urgently need a kind of hot pressing mechanism that can adapt to the surface of molding mold tire in the process of winding parts.

热压滚轮8是中空圆柱结构，内置有发热管和热电偶，由外部工控机控制热压滚轮内腔温度，热压滚轮有两个作用：一是预热缠绕中的复合材料布带，使布带更容易粘合在一起；二是缠绕过程中紧压模胎，进一步的压实已经缠绕上模胎上的布带。在热压滚轮两端伸出有连接块，用于与气缸和角度测量装置连接。The hot pressing roller 8 is a hollow cylindrical structure with built-in heating tubes and thermocouples. The temperature of the inner cavity of the hot pressing roller is controlled by an external industrial computer. The hot pressing roller has two functions: one is to preheat the composite material cloth tape during winding, so that The cloth tape is easier to bond together; the second is to press the mold tire tightly during the winding process, and further compact the cloth tape that has been wound on the upper mold tire. There are connecting blocks protruding from both ends of the hot pressing roller for connecting with the cylinder and the angle measuring device.
布带自适应缠绕机构是为了实现在缠绕零件时，能够使提供缠绕压力的热压滚轮8总能够紧密与成型模胎相贴合。。它涉及到气压传动控制及位移补偿技术。本实施例中，通过角度控制测量装置实现热压滚轮偏转及偏转角度测量，通过平移装置实现整体移动，对前点左右移动的距离进行补偿，保证热压滚轮偏转过程中热压前点位置始终保持不变。The cloth tape self-adaptive winding mechanism is to realize that when the parts are wound, the hot pressing roller 8 that can provide the winding pressure can always be closely attached to the molded tire. . It involves pneumatic transmission control and displacement compensation technology. In this embodiment, the deflection of the hot-pressing roller and the measurement of the deflection angle are realized by the angle control measuring device, and the overall movement is realized by the translation device, and the distance of the front point moving left and right is compensated to ensure that the position of the front point of the hot-pressing roller is always in the deflection process. constant.

The stepping motor 1 is fixed on the integral base plate 2 through the stepping motor fixing plate 10 , and the screw nut mechanism and the linear slide rail 3 are also fixed on the integral base plate 2 . The stepping motor is connected with the ball screw 12 through the coupling 11; the slider 4 cooperates with the linear slide rail 3, the screw nut and the slider are fixedly connected with the fixed plate 5, and the linear guide rail supports the fixed plate and the cylinder on the fixed plate, The role of hot pressing rollers and other parts. When the stepper motor rotates, the screw nut and the slide block drive the fixed plate 5 to slide along the linear slide rail.
角度控制测量装置包括气缸9和角度测量装置。本实施例中采用两个气缸，气缸安装在固定板5的一侧，气缸筒端部与固定板5通过销轴转动连接，气缸输出杆端部与热压滚轮一端连接块销轴转动连接。气缸可推动热压滚轮偏摆一定角度。The angle control measuring device comprises a cylinder 9 and an angle measuring device. In the present embodiment, two cylinders are used, and the cylinder is installed on one side of the fixed plate 5. The end of the cylinder barrel is connected with the fixed plate 5 through a pin shaft, and the output rod end of the cylinder is connected with the pin shaft of the connecting block at one end of the hot pressing roller. The air cylinder can push the hot pressing roller to deflect at a certain angle.
固定板5另一侧固定有左支撑板6，在左支撑板端部安装有角度测量装置。参照附图3，角度测量装置包括电位器7，连接轴15和支撑架14，支撑架14固定在左支撑板6端部，电位器7固定在支撑架14上，连接轴15穿过热压滚轮另一端的连接块，并通过滚针轴承16支撑；连接轴端部与电位器7固定连接。当热压滚轮偏转时，热压滚轮带动连接轴转动，并由连接轴带动电位器7转动，最终电位器7可检测到热压滚轮8的偏转角度。The other side of the fixed plate 5 is fixed with a left support plate 6, and an angle measuring device is installed at the end of the left support plate. With reference to accompanying drawing 3, angle measurement device comprises potentiometer 7, connecting shaft 15 and support frame 14, and support frame 14 is fixed on left support plate 6 ends, and potentiometer 7 is fixed on the support frame 14, and connecting shaft 15 passes through heat press The connecting block at the other end of the roller is supported by the needle bearing 16; the end of the connecting shaft is fixedly connected with the potentiometer 7. When the hot pressing roller deflects, the hot pressing roller drives the connecting shaft to rotate, and the connecting shaft drives the potentiometer 7 to rotate, and finally the potentiometer 7 can detect the deflection angle of the hot pressing roller 8 .
位移补偿技术的实现过程如下：当热压滚轮8旋转一定角度时，电位器7的输出电压信号发生变化，将此信号传送至工控机，根据角度和前点的水平位移之间关系进行换算，将热压滚轮位移量转化最终转化为控制器对步进电机1输出的脉冲信号。当有脉冲信号输送到步进电机时，步进电机转动一定角度，步进电机通过联轴器11与滚珠丝杠12相连接，滚动轴承13起支撑滚珠丝杠的作用，滑块4的移动带动整个热压滚轮等零件在左右方向移动。The implementation process of the displacement compensation technology is as follows: when the hot pressing roller 8 rotates at a certain angle, the output voltage signal of the potentiometer 7 changes, and this signal is transmitted to the industrial computer, and the conversion is performed according to the relationship between the angle and the horizontal displacement of the previous point. The displacement of the hot pressing roller is finally converted into a pulse signal output by the controller to the stepping motor 1 . When a pulse signal is sent to the stepping motor, the stepping motor rotates at a certain angle, the stepping motor is connected with the ball screw 12 through the coupling 11, the rolling bearing 13 plays the role of supporting the ball screw, and the movement of the slider 4 drives Parts such as the whole hot pressing roller move in the left and right directions.
应用本缠绕机构时，首先将布带绕过热压滚轮粘贴在缠绕零件上，气缸前进推动热压滚轮使之紧密与缠绕零件相贴合，然后启动主轴，缠绕零件转动时便通过布带带动热压滚轮旋转，使布带均匀受热。当缠绕零件的表面的布带倾斜角度发生变化时，造成了布带与热压滚轮不能很好的贴合，此时气缸便推动热压滚轮前进，使热压滚轮再次与缠绕零件的表面相贴合。在这个过程中的由于热压滚轮的偏摆的角度发生了变化，所以通过角度传感器实时检测偏摆角度的变化，并将数据传送到工控机中，工控机通过计算将热压滚轮需要水平移动的距离转换成步进电机旋转一定角度所需的脉冲数，并驱动步进电机旋转，从而实现了热压滚轮水平移动。从整个工作过程可以看出热压滚轮能够自适应与缠绕零件表面斜度的变化。When using this winding mechanism, first pass the cloth tape around the hot-pressing roller and stick it on the winding part, the cylinder advances to push the hot-pressing roller to make it fit closely with the winding part, then start the main shaft, and the winding part is driven by the cloth tape when it rotates The hot pressing roller rotates to make the cloth evenly heated. When the inclination angle of the cloth tape on the surface of the wound part changes, the cloth tape and the hot-pressed roller cannot fit well. At this time, the cylinder pushes the hot-pressed roller forward, so that the hot-pressed roller is in contact with the surface of the wound part again. fit. In this process, due to the change of the yaw angle of the hot-pressing roller, the angle sensor detects the change of the yaw angle in real time, and transmits the data to the industrial computer, and the industrial computer calculates the horizontal movement of the hot-pressing roller The distance is converted into the number of pulses required for the stepper motor to rotate at a certain angle, and the stepper motor is driven to rotate, thereby realizing the horizontal movement of the hot pressing roller. From the whole working process, it can be seen that the hot pressing roller can adapt to the change of the surface slope of the winding part.
