A welding fixture for the middle bracket assembly of the instrument panel beam

Abstract

The invention relates to a welding jig of an intermediate support assembly of an instrument board cross beam. The welding jig comprise an inverted F-shaped mounting rack, wherein the inverted F-shaped mounting rack is equipped with a first fixing frame; the first fixing frame is equipped with a first air cylinder and a first guide shaft; the first air cylinder and the first guide shaft are connected with a first linkage board; the first linkage board is connected with a hooked linkage rod; the hooked linkage rod is connected with a single-degree-of-freedom clamp distance adjustment device; the inverted F-shaped mounting rack is fixedly connected with a second fixing frame; the second fixing frame is equipped with a second air cylinder and a second guide shaft; the second air cylinder and the second guide shaft are connected with a second linkage board; the second linkage board is fixedly connected with a multiposition mounting board; the multiposition mounting board is provided with a forward convex mounting table and an upward convex mounting table; the forward convex mounting table is connected with a single-degree-of-freedom location distance adjustment device; and the upward convex mounting table is connected with double-degree-of-freedom hole fixing and position adjustment device. The jig has the advantages of reasonable structural design, high automation degree, convenience in control and the like, can realize location and clamp dimension adjustment in X, Y and Z directions, and ensures reliable clamp and location.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a welding jig for an instrument panel beam intermediate bracket assembly. Background technique [0002] The middle left bracket assembly and the middle left bracket assembly (hereinafter collectively referred to as the middle bracket assembly) on the cross beam of the automobile instrument panel play an important role in the cross beam of the instrument panel. It can also enhance the overall structural strength of the instrument panel beam. It can be seen that the accuracy of the fixed connection of the intermediate bracket assembly will also have a certain impact on the overall accuracy and performance of the instrument panel beam. At present, the factory uses welding to connect the intermediate bracket assembly with the outer circular surface of the intermediate air outlet pipe installation bracket. Since the middle part of the intermediate bracket assembly bends ...

AI Technical Summary

Problems solved by technology

At present, the factory uses welding to connect the intermediate bracket assembly with the outer circular surface of the intermediate air outlet pipe installation bracket. Since the middle part of the intermediate bracket assembly bends downwards in a certain arc, and along the length direction of the intermediate bracket assembly There are flanges on the upper and lower sides, and a waist-shaped concave reinforcing rib along the middle of the middle bracket assembly in the length direction, which brings certain difficulties to the positioning and clamping of the middle bracket assembly. It is not accurate enough, and it will also affect the position accuracy of other components such as the upper mounting bracket assembly in the middle of the IP body and the lower mounting bracket assembly in the middle of the IP body

Existing factories mostly use manual clamping to clamp and position the middle part of the intermediate bracket assembly, the operation efficiency is relatively low, which affects the production efficiency of the instrument panel beam, and due to the unreasonable structural design of the clamp itself, it cannot be Positioning and clamping positions are adjusted, which is inconvenient for the positioning and clamping of the intermediate bracket assembly, which affects the efficiency of product processing

At present, although automatic clamping control has been gradually applied in the field of automobile production technology, which has improved the efficiency of clamping, the flexibility and adjustability of the manufactured clamps are poor, and the adjustment of the installation and positioning dimensions of the clamp itself cannot be realized. This makes the fixture only suitable for clamping parts of a certain type of fixed size, and the applicable surface is narrow
