Bonding jig for simultaneous bonding of two switch brackets to the fume hood

Abstract

The invention relates to a bonding clamp of bonding two switch supports to a smoke collecting cover at the same time. the device comprises a table board, a bonding structure, a second positioning block and two sets of tight pressing mechanism, wherein the bonding clamp of bonding two switch supports to the smoke collecting cover at the same time is characterized in that the bonding structure comprises a first positioning block, first stop dogs are fixed on the front side, the rear side and the outer side of the first positioning block, and the top face of the first positioning block is fixedlyprovided with a first positioning column; the second positioning block is constrained on the table board and only can slide left and right, second positioning blocks are fixed on the front side, therear side and the outside of the second blocking block, second positioning columns are arranged on the top face of the second positioning block; the two sets of tight pressing mechanisms are arrangedon the table board; and the pushing downwards of the two sets of tight pressing mechanisms can correspondingly tight press a first switch support and a second switch support on the inner surface of the front end face of the smoke collecting cover for bonding and pressure maintaining. According to the clamp, through the floating design of the second positioning block, fine adjustment on the left and right positions of the second positioning block can be realized, and the second positioning column can be ensured to be inserted into a switch hole; and the two switch supports can be bonded at onetime by adopting a set of the clamp, so that the manufacturing cost of the clamp is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a bonding tool for bonding a certain part to another part, in particular to a bonding fixture for bonding two switch brackets to a smoke collecting hood at the same time. Background technique [0002] The fume collecting hood is the main part of the range hood. It is generally formed by punching and bending thin steel plates and then welded. The fume collecting hood has a top surface with a middle opening. The front face, left end face and right end face of the front end face, the left end face and the right end face, and the parts where the front end face, the left end face and the right end face are in contact with each other are fixed together by laser welding. The switch bracket is glued on the smoke collecting hood, and generally there are two switch brackets, which are respectively located on the left and right sides. [0003] The bonding of the switch bracket requires high precision for its positioning, because the swit...

AI Technical Summary

Problems solved by technology

The center distance of the switch holes in the front of the fume collecting hood due to the middle part being cut and then welded is relatively large. The bonding method on the smoke hood is independent bonding. Originally, the left and right fixed positioning is used. The left and right switch brackets cannot be bonded at one time, and need to be bonded twice, which means that two sets of special bonding fixtures are required, and Bonding efficiency is greatly reduced, time-consuming
