装配治具

Abstract

一种装配治具，包括：套筒机构，围合形成有一端开口的容纳空间；插销件自套筒件的开口置入容纳空间，插销件沿轴向上具有形变段，且形变段的外径沿远离套筒件的方向逐渐增大；驱动机构，连接于套筒机构；驱动机构用于控制套筒件和插销件沿轴向相互靠近，以使得套筒件抵接并推动开口金属卡环相对于插销件移动，且开口金属卡环的尺寸沿形变段逐渐增大，至套设于沉槽内。由于开口金属卡环可以顺着形变段的发生均匀变形的同时向靠近装配支架的方向运动，直到开口金属卡环卡接于装配支架的沉槽内，免去了人手操作从而避免了受伤，而且装配过程中开口金属卡环的形变量稳定可控，有效的防止了损坏开口金属卡环和装配支架。

Claims

1. An assembly fixture for mounting an open metal retaining ring to an assembly bracket, wherein the outer circumferential surface of the assembly bracket is provided with a countersunk groove; characterized in that, The assembly fixture includes: A sleeve mechanism includes a sleeve member and a pin member arranged axially opposite each other. The sleeve member encloses a receiving space with one end open. The pin member is inserted into the receiving space through the opening of the sleeve member. The pin member has a deformation section along the axial direction, and the outer diameter of the deformation section gradually increases in the direction away from the sleeve member. The pin member is used to fit the open metal retaining ring, and the end of the pin member away from the sleeve member along the axial direction is used to fix the assembly bracket. A drive mechanism is connected to the sleeve mechanism; the drive mechanism is used to control the sleeve and the pin to move closer to each other along the axial direction, so that the sleeve abuts against and pushes the open metal retaining ring to move relative to the pin, and the size of the open metal retaining ring gradually increases along the deformation section until it is fitted into the sink groove.

2. The assembly fixture of claim 1, wherein The sleeve includes a plurality of circumferentially arranged support pieces, with a preset gap between adjacent support pieces; each support piece includes a fixed end and a free end arranged opposite to each other, the fixed end of each support piece is away from the pin and fixedly connected, and the free end of each support piece extends along the axial direction toward the deformation section.

3. The assembly fixture of claim 1, wherein The end of the pin away from the sleeve is provided with a plug-in portion for insertion into the assembly bracket to form a fixed connection with the assembly bracket.

4. The assembly fixture of claim 1, wherein, The outer diameter of the end of the deformed section away from the sleeve is greater than or equal to the outer diameter of the assembly bracket.

5. The assembly fixture of claim 1, wherein The assembly fixture further includes a base, and the end of the sleeve component away from the pin component is fixedly disposed on the base; the drive mechanism is fixedly disposed on the base, and the drive mechanism is connected to the end of the pin component away from the sleeve component.

6. The assembly fixture of claim 5, wherein, The drive mechanism includes a connecting rod and a drive assembly. One end of the connecting rod is connected to the pin, and the other end is movably connected to the drive assembly.

7. The assembly fixture of claim 6, wherein, The sleeve mechanism includes at least two sets, and each sleeve mechanism is arranged in parallel on the base; the assembly fixture also includes a drive plate, which is suspended above the base, and the two ends of the drive plate along the axial direction are respectively connected to the connecting rod and the corresponding pin of each sleeve mechanism.

8. The assembly fixture of claim 7, wherein, The drive plate and the base are connected by an elastic connector, which causes the drive plate and the base to tend to move away from each other.

9. The assembly fixture of claim 7, wherein, It also includes at least one slide rail component, which extends along the axial direction, is fixedly connected to the base, and is slidably connected to the drive plate.

10. The assembly fixture as described in claim 6, characterized in that, The drive assembly includes a guide and a grip. The guide has a guide groove extending along the axial direction, and the connecting rod passes through the guide groove. The grip is rotatably connected to the guide in a first direction, which is perpendicular to the axial direction.
