Mounting positioning device for automobile tail door hinge

Abstract

The invention provides a mounting positioning device for an automobile tail door hinge and belongs to the field of tool clamps used for automobile production. The mounting positioning device comprises a telescopic positioning mechanism and a turnover clamping mechanism. The telescopic positioning mechanism comprises a telescopic cylinder assembly, a hinge supporting block, side face limiting plates and a limiting block, wherein the hinge supporting block is connected with a piston head of the telescopic cylinder assembly and limits the position of the tail door hinge in the X direction, the side face limiting plates are arranged on the two sides of the hinge supporting block and used for limiting the position of the hinge in the Y direction, and the limiting block is arranged below the hinge supporting block and used for limiting the tail door hinge. The turnover clamping mechanism comprises a turnover cylinder assembly, a first pressing block and a second pressing block, wherein the first pressing block and the second pressing block are connected with the turnover cylinder assembly. The first pressing block can turn over and compress the hinge supporting block. The second pressing block can be matched with the limiting block to compress the tail door hinge. The mounting positioning device has the beneficial effects that a certain full control faces are utilized to achieve full positioning to position the hinge, and positioning deviation caused by imprecise positioning of a hinge screw is reduced.

Description

technical field [0001] The invention relates to the field of tooling fixtures for automobile production, in particular to an automobile tailgate hinge installation and positioning device. Background technique [0002] The hinge positioning structure in the prior art swings the pressure plate and the hinge limit block into place through the first cylinder, snaps the two screw rods of the hinge into the two grooves of the limit block, and attaches the hinge to the side where the body is installed To the surface of the limit block, use two slots to limit the position of the hinge in the Y direction, and then use the hinge limit block to limit the position of the hinge in the Z direction, and then push the clamping block in place by the second cylinder, The hinge is clamped, and then the hinge is tightened on the tailgate by bolts. [0003] This structure has the following problems: [0004] Because the two slots of the hinge limit block cannot be made in full contact with the...

AI Technical Summary

Problems solved by technology

[0004] Because the two slots of the hinge limit block cannot be made in full contact with the screw of the hinge, otherwise it will cause difficulty in mounting parts. At the same time, the surface of the hinge screw is threaded and is not suitable for use as a positioning surface, so the hinge relies on two screws. To limit the inaccurate positioning in the Y direction; when the tailgate assembly is installed on the body-in-white, it is easy to cause step difference and gap mismatch, which requires repeated adjustments, affecting the quality and production cycle of the body-in-white assembly
