A composite torsion beam positioning detection device

Abstract

The present invention discloses a novel composite type torsion beam positioning detection device. The device is characterized in that the device comprises a bottom plate; the bottom plate is providedwith X-direction limiting devices, a Y-direction clamping device, Z-direction limiting and clamping devices and detection devices; each Z-direction limiting and clamping device comprises a supportingstage and a Z-direction quick clamp which is located above the supporting stage and is matched with the supporting stage; each detection device comprises a detection supporting seat and a detection pin which movably extends out from the detection supporting seat; and the detection pins are located in spaces formed by the supporting stages of the Z-direction limiting and clamping devices and the Z-direction quick clamps when the Z-direction quick clamps are in clamping states. According to the novel composite type torsion beam positioning detection device, after X-direction positioning and Y-direction positioning are performed, the Z-direction limiting and clamping devices position two ends of each of a left dragging arm and a right dragging arm of a torsion beam in a Z direction, in this condition, the torsion beam can be positioned the most firmly, so that the detection device is arranged there, and therefore, detection can be performed under a stable state; and when the detection pins can pass through bushing holes, a part is qualified.

Description

technical field [0001] The invention relates to the field of auto parts detection, in particular to a composite torsion beam positioning detection device. Background technique [0002] The product of the rear torsion beam with hinge assembly is formed by bending and welding multiple sheet metals, and will be connected with other products, which makes the hole position and positioning surface of the torsion beam with hinge assembly have precision requirements. As disclosed in Chinese Utility Model No. 2016208529910, the rear torsion beam includes a crossbeam and left and right trailing arms at both ends. Spring discs are provided between the left and right trailing arms and the crossbeam, and shock absorbers are provided between the spring discs on both sides and the trailing arms. In the installation part of the device, the spring plate is provided with water leakage holes at intervals along the circumference, and the ends of the left and right trailing arms are provided wit...

AI Technical Summary

Problems solved by technology

[0003] At present, each OEM does not have a detection device for the bushing hole of the torsion beam. As a result, when the torsion beam is assembled with other mechanical components, it often occurs that the assembly cannot be assembled or the wrong hole phenomenon occurs, which seriously affects the normal assembly of the final assembly of the vehicle factory. craft
