如图1-2中所示，本发明提供一种顶出工具，适用于过盈装配的工件的拆卸，尤其适用于缸盖上的碗形塞等圆形工件的拆卸。As shown in Figs. 1-2, the present invention provides an ejector tool, which is suitable for the disassembly of workpieces fitted with interference, and is especially suitable for the disassembly of circular workpieces such as bowl-shaped plugs on cylinder heads.
本发明的顶出工具包括：顶出件、支撑件和调节组件，顶出件和支撑件分别设置在待拆工件的两侧，并且顶出件和支撑件通过调节组件相连，调节组件带动顶出件向靠近支撑件的方向移动，以使顶出件顶出待拆工件。The ejector tool of the present invention includes: an ejector, a support and an adjustment assembly, the ejector and the support are respectively arranged on both sides of the workpiece to be disassembled, and the ejector and the support are connected through the adjustment assembly, and the adjustment assembly drives the ejector The ejector moves toward the direction close to the support, so that the ejector ejects the workpiece to be dismantled.
本发明中，通过调节组件带动顶出件向靠近支撑件的方向移动，以将待拆工件慢慢顶出，从而实现了工件的拆卸，尤其适用于过盈装配的工件的拆卸，代替了暴力拆卸，可避免对被拆卸部位造成额外的损坏。In the present invention, the adjusting component drives the ejector to move in the direction close to the support, so that the workpiece to be disassembled is slowly ejected, thereby realizing the disassembly of the workpiece, which is especially suitable for the disassembly of the workpiece with interference assembly, instead of violent disassembly to avoid additional damage to the part being disassembled.
具体地，支撑件和顶出件均沿第一方向延伸并平行设置，调节组件带动顶出沿第二方向移动以靠近支撑件，其中第一方向与第二方向垂直。例如，第一方向为水平方向，第二方向为垂直方向。Specifically, both the support member and the ejector member extend along a first direction and are arranged in parallel, and the adjusting assembly drives the ejector member to move along a second direction to approach the support member, wherein the first direction is perpendicular to the second direction. For example, the first direction is a horizontal direction, and the second direction is a vertical direction.
本发明的顶出工具，结构简单，使用方便，能够降低拆卸所需要的时间，提高拆卸效率。在使用时，将顶出件放置在待拆工件的下方，将支撑件放置在待拆工件的上方(具体为待拆工件的安装部位的上表面上)，再通过调节组件将支撑件和顶出件连接在一起，然后通过调节组件带动顶出件向靠近支撑件的方向(向上)移动，从将待拆工件从其安装部位处顶出。The ejecting tool of the invention has simple structure and convenient use, can reduce the time required for disassembly, and improve the disassembly efficiency. When in use, the ejector is placed under the workpiece to be removed, the support is placed above the workpiece to be removed (specifically, on the upper surface of the installation part of the workpiece to be removed), and then the support and the ejector are moved through the adjustment assembly. The ejection pieces are connected together, and then the ejection piece is driven by the adjusting assembly to move toward the direction (upward) close to the support piece, so as to eject the workpiece to be disassembled from its installation position.
此外，本发明的调节组件不包含电气或液压等驱动部件，结构简单，占用空间小。In addition, the adjusting assembly of the present invention does not include electric or hydraulic driving components, has a simple structure, and occupies a small space.
在一个实施例中，调节组件包括：第一螺纹件1和第二螺纹件2，其中，第一螺纹件1和/或第二螺纹件2限位式连接于支撑件上，第一螺纹件1的端部和第二螺纹件2的端部分别穿过支撑件与顶出件的相应的侧部螺纹连接，通过转动第一螺纹件1和第二螺纹件2能够带动顶出件向靠近支撑件的方向移动。In one embodiment, the adjustment assembly includes: a first threaded
具体地，支撑件和顶出件沿水平方向延伸，第一螺纹件1和第二螺纹件2沿垂直方向延伸，第一螺纹件1的端部和第二螺纹件2的端部分别穿过支撑件与顶出件的相应的侧部螺纹连接，换言之，第一螺纹件1与第二螺纹件2未与支撑件之间形成螺纹连接，支撑件用于安装并对调节组件起到限位的作用。Specifically, the support member and the ejection member extend in the horizontal direction, the
在本实施例中，第一螺纹件1和第二螺纹件2与顶出件形成一个类似丝杠的结构，可将旋转运动转化成直线运动。这样，在转动第一螺纹件1和第二螺纹件2时，由于第一螺纹件1和/或第二螺纹件2限位式连接在支撑件上，第一螺纹件1和第二螺纹件2与支撑件的相对位置不会发生变化，即第一螺纹件1和第二螺纹件2转动时，其不能在第二方向移动，从而使顶出件沿着第一螺纹件1和第二螺纹件2向靠近支撑件的方向直线运动，以顶出待拆工件。In this embodiment, the first threaded
并且，通过设置第一螺纹件1和第二螺纹件2两个螺纹件与顶出件螺纹连接，用于限制顶出件以其中一个螺纹件为轴旋转，从而在转动第一螺纹件1和第二螺纹件2时，能够将扭紧力传递至顶出件，带动其沿直线运动。In addition, by setting the first threaded
需要说明的是，顶出待拆工件时，需同时转动第一螺纹件1和第二螺纹件2。It should be noted that, when the workpiece to be disassembled is ejected, the first threaded

具体地，支撑件上设置设有第一通孔8和第二通孔9，第一螺纹件1和第二螺纹件2分别对应地设置于第一通孔8和第二通孔9中，并且第一螺纹件1的外壁与第一通孔8的孔壁之间有间距，第二螺纹件2的外壁与第二通孔9的孔壁之间有间距。换言之，支撑件上分别设置第一通孔8和第二通孔9用于穿设第一螺纹件1与第二螺纹件2，并且使其之间未形成螺纹连接，从而转动第一螺纹件1和第二螺纹件2时，支撑件的位置不变。Specifically, the support member is provided with a first through
进一步具体地，第一螺纹件1通过限位螺母7限位式连接于支撑件上，其中，限位螺母7螺纹连接于第一螺纹件1上，并且限位螺母7的底面与支撑件的远离顶出件的一侧相抵。More specifically, the first threaded
需要说明的是，限位螺母7也可以设置在第二螺纹件2上，由于第一螺纹件1和第二螺纹件2通过顶出件连接在一起，则仅在其中一个螺纹件上设置限位螺母7即可实现对两个螺纹件的限位式连接功能。It should be noted that the
在本实施例中，调节组件(第一螺纹件1和第二螺纹件2)的一端通过螺纹与顶出件连接，其另一端则通过限位螺母7与支撑件相连。换言之，限位螺母7作为限位件和连接件，使第一螺纹件1、第二螺纹件2以及顶出件连接在支撑件上，并且在未转动第一螺纹件1和第二螺纹件2时，第一螺纹件1、第二螺纹件2、顶出件和支撑件四者的位置固定。同时，限位螺母7可直接螺纹连接于第一螺纹件1上，安装方便。In this embodiment, one end of the adjusting assembly (the first threaded
具体地，顶出件的两侧部上分别设置有贯通的第一螺纹孔10和第二螺纹孔11，第一螺纹件1的端部和第二螺纹件2的端部分别螺纹连接于第一螺纹孔10和第二螺纹孔11中。从而实现顶出件与第一螺纹件1和第二螺纹件2之间的螺纹连接。Specifically, a first threaded

在另一个实施例中，调节组件包括：调节螺杆和螺纹连接在调节螺杆上的调节螺母，其中，调节螺杆的端部穿过支撑件与顶出件可拆卸相连，调节螺母的底面与支撑件的远离顶出件的一侧相抵，通过转动调节螺母使调节螺杆沿与支撑件垂直的方向移动，从而带动顶出件向靠近支撑件的方向移动。In another embodiment, the adjustment assembly includes: an adjustment screw and an adjustment nut threaded on the adjustment screw, wherein the end of the adjustment screw is detachably connected to the ejector through the support, and the bottom surface of the adjustment nut is connected to the support The side away from the ejector is pushed against each other, and the adjusting screw is moved in a direction perpendicular to the support by rotating the adjusting nut, thereby driving the ejector to move toward the direction close to the support.
具体地，调节螺杆的端部与顶出件螺纹连接。Specifically, the end of the adjusting screw is screwed with the ejector.
在本实施例中，调节螺杆与顶出件安装在一起后，两者的位置相对固定。而通过转动调节螺母使调节螺杆沿与支撑件垂直的方向移动，从而带动顶出件向靠近支撑件的方向移动，其中，调节螺母与支撑件的位置相对固定，即调节螺母在第二方向(垂直方向)上的位置不变，从而将螺母的旋转运动转化为调节螺杆的直线运动，进而带动顶出件向靠近支撑件的方向移动。In this embodiment, after the adjusting screw and the ejector are installed together, the positions of the two are relatively fixed. By rotating the adjusting nut, the adjusting screw is moved in a direction perpendicular to the support, thereby driving the ejector to move in a direction close to the support, wherein the positions of the adjusting nut and the support are relatively fixed, that is, the adjusting nut is in the second direction ( The position in the vertical direction) remains unchanged, so that the rotary motion of the nut is converted into the linear motion of the adjusting screw, and then the ejector is driven to move toward the direction close to the support.
优选地，上述调节组件还包括：限位螺杆，限位螺杆与调节螺杆分别穿过支撑件的两侧与顶出件的两侧部可拆卸相连。其中，限位螺杆用于防止顶出件的转动，进而防止转动调节螺母时调节螺杆发生转动。Preferably, the above-mentioned adjustment assembly further comprises: a limit screw, the limit screw and the adjustment screw respectively pass through two sides of the support member and are detachably connected to the two sides of the ejection member.
