Fixture for positioning automotive front door

Abstract

The invention discloses a fixture for positioning an automotive front door. The fixture comprises a framework, a first Y-direction limiting stopper, a second Y-direction limiting stopper, a first Z-direction limiting stopper, a second Z-direction limiting stopper, and an independently arranged X-direction limiting slider, wherein the first Y-direction limiting stopper and the second Y-direction limiting stopper are fixedly arranged on the framework and are arranged at the right side of the framework back and forth at interval, the right sides of the first Y-direction limiting stopper and the second Y-direction limiting stopper are provided with one presser respectively and correspondingly; the first Z-direction limiting stopper is located in front of the first Y-direction limiting stopper, and the second Z-direction limiting stopper is located behind the second Y-direction limiting block; and a limiting rib is arranged at the left side of the X-direction limiting slider and is fit with a gap between the front door and a rear door in shape and thickness, and a fixture positioning pin X capable of being inserted into a positioning hole of a white automotive body is fixedly arranged below the framework. According to the invention, repeated debugging is not needed, the fixture can be used for regulating the front door to an assembly position in one step, so that the operation is simple as well as time-saving and labor-saving.

Description

technical field [0001] The invention relates to an automobile assembly tool, in particular, a tool for installing the front door of an automobile. Background technique [0002] The front door of the car is installed on the body-in-white of the car, which is the last link of the vehicle assembly, so the accumulated assembly error is relatively large. When installing the front 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-right), and Z-direction (that is, up and down) on the body-in-white in order to ensure the front door after installation. Consistency and aesthetics. At present, there is no special tooling for the installation of the front 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...

At present, there is no special tooling for the installation of the front 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 repeatedly perform complex adjustments, which is time-consuming and laborious. Even in the end, it can't achieve the expected effect
