Smoke baffle bonding fixture

Abstract

The invention relates to an adhesion clamp for a smoke baffle. The adhesion clamp for the smoke baffle comprises a frame. The frame is provided with a table top, an upper mounting plate and at least one set of adhesion structure. The adhesion clamp for the smoke baffle is characterized in that the adhesion structure comprises a shelf, a circumferential limiting structure, two L-shaped limiting blocks and two pressing mechanisms; the circumferential limiting structure is used for restraining the smoke baffle in the circumferential direction, and comprises a front positioning block, a rear positioning block, a left positioning block and a right positioning block; the front positioning block and the rear positioning block are fixed to the shelf; the left positioning block and the right positioning block are restrained on the shelf and can slide left and right synchronously; the two L-shaped limiting blocks are used for limiting rotary shaft components, and can move vertically under driving of an air cylinder mounted on the upper mounting plate; and the two pressing mechanisms can press the rotary shaft components onto the upper end face of the smoke baffle to maintain the pressure for adhesion. By means of the adhesion clamp, the rotary shaft components can be accurately and firmly mounted onto the smoke baffle, the dimensions of the rotary shaft components at the two ends of the smoke baffle can be accurate, the both sides are balanced in error, and the situation that errors are lumped at one end is avoided.

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 precisely and rapidly bonding a rotating shaft part to a smoke baffle. Background technique [0002] There is a smoke baffle at the air inlet of some high-end range hoods. The smoke baffle is hinged at the air inlet of the range hood through the rotating shaft. When it is not in use, the smoke baffle covers the air inlet, making the appearance more beautiful and preventing impurities from entering. When the range hood is in use, the smoke baffle is turned outward to open the air inlet, and the smoke baffle blocks the oil fume so that all the oil fume can be sucked into the air inlet as much as possible. [0003] Such a smoke baffle structure is disclosed in a Chinese invention patent "A Range Hood with Automatic Opening and Closing of Smoke Screen" with patent number ZL201210230513.2 (notification number CN102767857B). In order to...

Problems solved by technology

[0004] At present, there are mainly two ways to bond the shaft parts to the back of the glass smoke baffle: one is the traditional bonding, which uses manual bonding of the shaft parts to the glass smoke baffle one by one. The efficiency is extremely low. On the premise of increased labor costs, the processing cost has increased significantly, and because there is no pressure-holding step, the bonding of the shaft parts is not reliable, and the glass smoke baffle is easy to detach from the glass smoke baffle. Manual bonding will make the bonding position of the smoke baffle made of glass relative to the smoke baffle made of glass imprecise, which requires high technical requirements for workers

The other is to use simple bonding tooling to bond the rotating shaft parts. At present, the simple tooling has the following defects. One is that the size and position of the bonding are not easy to ensure the accuracy is low, and the positioning of the rotating shaft parts and the glass smoke shield is not good. If it is tight, it is easy to dislocate after bonding, and the size of the rotating shaft parts at both ends of the smoke baffle is easy to be inconsistent, so that the smoke baffle cannot be accurately installed on the range hood; low connection efficiency
