Assembly sample frame and assembly method for ensuring engagement of hatchback door lock and lock catch

Abstract

The invention discloses an assembly sample frame and an assembly method for ensuring meshing of a hatchback door lock and a lock catch. The assembly sample frame comprises a sample frame support, and the sample frame support is provided with a sample frame vehicle body fixing structure used for enabling the sample frame support to be installed and fixed on a vehicle body. A sample frame lock catch installation structure used for installing a back door lock catch is arranged on the lower portion of the side, facing the vehicle body, of the sample frame support, and a sample frame back door installation structure capable of enabling a back door to be installed and positioned on the sample frame support is arranged on the side, facing the back door, of the sample frame support. The back door lock catch is installed on the sample frame and then connected with the vehicle body, the relative installation position accuracy of the sample frame and the vehicle body is guaranteed, then the back door is installed on the basis of the sample frame, the relative installation position accuracy of the back door and the vehicle body is guaranteed, the relative position accuracy of the back door and the back door lock catch is guaranteed, and the meshing state of the back door lock and the back door lock catch is guaranteed. And the problems of difficulty in closing the back door, jamming, abnormal sound and the like are avoided. And station arrangement is optimized, and investment and working hours of tools, tightening tools and manpower are reduced.

Description

technical field [0001] The invention relates to the technical field of assembling tools for automobile parts, in particular to an assembling sample frame and an assembling method for ensuring the engagement of a hatchback door lock and a lock catch. Background technique [0002] The shape design of the hatchback door requires that the hinge shaft of the back door be installed inside the top cover. The back door cannot adopt the traditional self-positioning scheme and needs to be assembled by using the profile positioning. However, the back door latch follows the self-positioning scheme for design and assembly. The problem with this assembly method is that the assembly reference is not uniform, and it is difficult to ensure the relative positional relationship between the hatchback door and the latch, resulting in the back door lock and latch. The meshing state is not good, causing problems such as difficulty in closing, card issuance, abnormal noise, etc. SUMMARY OF THE I...

Problems solved by technology

The back door cannot adopt the traditional self-positioning scheme, but needs to be assembled by surface positioning

However, the back door lock is designed and assembled following the self-positioning scheme. The problem with this assembly method is that the assembly reference is not uniform, and it is difficult to ensure the relative positional relationship between the liftback door and the lock, resulting in the back door lock and the lock. The meshing state is not good, which causes problems such as difficulty in closing, card issuance, abnormal noise, etc.
