Back door ancillary supporting tool

Abstract

The invention discloses a back door ancillary supporting tool which comprises a bottom supporting assembly, a left side body supporting assembly and a right side body supporting assembly. The bottom supporting assembly comprises a limiting supporting block, a transferring block and a bottom supporting block which are sequentially and fixedly connected from top to bottom; and the bottom supportingassembly is supported between the bottom of a back door and the tail of a car side body, the left side body supporting assembly comprises a left supporting block and a left positioning block which arefixedly connected and is supported between the left side of the back door and the left side of the car side body, and the right side body supporting assembly comprises a right supporting block and aright positioning block which are fixedly connected and is supported between the right side of the back door and the right side of the car side body. According to the back door ancillary supporting tool, a gap between the back door and the side body is kept through the bottom supporting assembly, the left side body supporting assembly and the right side body supporting assembly, natural falling ofthe back door due to gravity is avoided, the actual installing state of the back door is simulated, the accuracy and the stability of the assembly size are effectively guaranteed, manual supporting of the back door through a worker is avoided, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an auxiliary support tool for a rear door. Background technique [0002] With the development of the automobile industry, the production scale of automobiles is constantly increasing. In order to improve production efficiency, reduce the number of reworks, and increase the yield, the quality of automobile bodies must be strictly controlled. The assembly of the four doors and two covers of the car is the key and difficult point of the car assembly, especially the gap between the four doors and the two covers and the side wall of the car is the primary factor determining the appearance quality of the vehicle. [0003] Among the outer covering parts of the car body, the back door is an important appearance part on the car body. The accuracy of the back door directly affects the matching accuracy with the side wall and taillights. However, the parts that cooperate wi...

Problems solved by technology

[0003] Among the outer covering parts of the car body, the back door is a relatively important appearance part on the car body. The accuracy of the back door directly affects the matching accuracy with the side wall and taillights. However, the parts that cooperate with the back door are very Many, including side panels, rear bumpers and taillights, etc.; and when the rear door is assembled, modules such as the rear bumper and taillights have not been installed, so the installation of the rear door lacks reference; when the rear bumper and taillights are not installed Under such circumstances, the back door lacks support, and under the influence of gravity, the back door is easy to sag, thereby making contact with the side wall and the inner panel of the back wall, resulting in a difference in the surface of the back door during the evaluation of the body-in-white The gap cannot be detected; therefore, in actual detection, it is necessary to use manual lifting for detection, but the consistency of manual operation is poor, it is difficult to ensure the stability of the assembly size, and it is impossible to keep the position of the back door in the design state and accurately reflect the back door. Clearance between doors and side panels, rear panel and taillights

Therefore, it is very difficult to control the assembly accuracy of the back door, which has become a major problem for R&D personnel.
