Positioning fixture of rear door of automobile

Abstract

The invention discloses a positioning fixture of a rear door of an automobile. The positioning fixture comprises a framework, an X-direction limiting oblique block, a first Y-direction limiting block, a second Y-direction limiting block, a first Z-direction limiting block and a second Z-direction limiting block, wherein the first and second Y-direction limiting blocks are fixedly arranged on the right side of the framework and arranged at the front part and the rear part at an interval, and a compactor is respectively correspondingly arranged on the right side of each of the first and second Y-direction limiting blocks; the first Z-direction limiting block is fixedly arranged in front of the first Y-direction limiting block, and the second Z-direction limiting block is fixedly arranged behind the second Y-direction limiting block; and the X-direction limiting oblique block is positioned at the back upper part of the second Z-direction limiting block, a limiting boss is arranged on the left side of the X-direction limiting oblique block, the shape and thickness of the limiting boss tally with those of a gap between the rear door and a body in white, and a fixture positioning pin which can be inserted into the positioning hole of the body in white is fixedly arranged below the framework. Repeated debugging is not required, the fixture can be used for adjusting the rear door to an assembly position once, and the operation is simple, time-saving and labor-saving.

Description

technical field [0001] The invention relates to an automobile assembly tool, in particular, a tool for installing the rear door of an automobile. Background technique [0002] The rear door of the car is installed on the body-in-white of the car, which is the last link of vehicle assembly, so the accumulated assembly error is relatively large. When installing the rear door of a car, it is necessary to control the gaps and surface differences in the X direction (that is, front and rear), Y direction (that is, left and right), and Z direction (that is, up and down) on the body-in-white in order to ensure the rear door after installation. Consistency and aesthetics. At present, there is no special tooling for the installation of the rear door of the car. Large-scale fixtures are generally used for positioning. Although the operation is relatively simple, the manufacturing cost of the fixture is relatively high, and the assembly cannot be completed at one time. It requires expe...

Problems solved by technology

At present, there is no special tooling for the installation of the rear door of the car. Large-scale fixtures are generally used for positioning. Although the operation is relatively simple, the manufacturing cost of the fixture is relatively high, and the assembly cannot be completed at one time. It requires experienced installers to perform complex adjustments repeatedly, which is time-consuming and laborious. Even in the end, it can't achieve the expected effect
