[0024] As mentioned above, in actual use of this case, the motor 5 is started to drive the rotating plate 201 to rotate counterclockwise by 45°, and the slide bar 202 rotates with the arc-shaped slide of the rotating plate 201, moves from one end of the arc-shaped slide to the other end, and moves in parallel. The slide plate 2021 at the bottom of the slide bar 202 then slides horizontally inside the guide block 204, driving the clamping block 203 on one side to move outward, and the motor 5 is turned off. After the fire damper is placed on the placement table 205, the motor 5 is started again to drive the rotating plate 201 to rotate clockwise. The movement of the mechanism drives the clamping block 203 to move inward, and rotates until the clamping blocks 203 on all sides clamp the fire damper, and then the control panel is used to start the welding assembly 3 and the dust collection assembly 4 on the top of the bracket 101 to perform welding and dust collection respectively.

[0025] The welding assembly 3 includes an annular electromagnetic slide rail 301 connected to the bottom of the bracket 101, a sliding telescopic rod 302 is slidably connected inside the annular electromagnetic slide rail 301, an adjusting rod 303 is connected to the bottom of the sliding telescopic rod 302, a solder box 304 is connected to one side of the adjusting rod 303, and a telescopic welding head 305 is connected to the bottom of the solder box 304. The dust collection assembly 4 includes a dust collector head 401 fixed to the bottom of the bracket 101, and the tail pipe of the dust collector head 401 passes through the top of the bracket 101 and is connected to the vacuum cleaner body 402.

[0026] As described above, by operating the control panel on one side of the bracket 101, the movement of each component of the welding assembly 3 is controlled, and the sliding telescopic rod 302 is controlled to slide inside the annular electromagnetic slide rail 301. The sliding telescopic rod 302 drives each connection assembly to rotate for position adjustment. The position adjustment is controlled by controlling the adjusting rod 303. The up and down position adjustment is controlled by controlling the sliding telescopic rod 302 and the telescopic welding head 305, so that the welding position is convenient to adjust and the welding efficiency is greatly improved. An adjustable dust collector 401 is connected to the bottom of the bracket 101, and the dust and impurities generated by the welding are transported to the dust collector body 402 at the top of the bracket 101 through the aisle, so as to reduce smoke and pollution and improve work efficiency and service life of the device.

[0027] A rubber block 2031 is pasted on one side of the clamping block 203, and an adjusting plug 2032 is set on one side of the clamping block 203. Multiple threaded holes are opened on the adjusting plug 2032, and a threaded hole is opened on the slide plate 2021. After moving the appropriate threaded hole on the adjusting plug 2032 to the threaded hole on the slide plate 2021, it is fixed with bolts.

[0028] As mentioned above, the rubber block 2031 is bonded to one side of the clamping surface of the clamping block 203, which can effectively increase the clamping force and protect the surface of the workpiece. An adjusting plug block 2032 is set on one side of the clamping block 203, and multiple threaded holes are opened on the adjusting plug block 2032. A threaded hole is opened on the top of the slide plate 2021. The threaded hole to be used is selected to fix the clamping block 203, and the adjustment amount of the clamping block 203 is increased to adapt to fire dampers of more sizes.

[0029] A positioning plug 2041 is designed at the bottom of the guide block 204, and four evenly distributed T-shaped grooves are opened inside the guide block 204, and the bottom of the slide plate 2021 slides inside the T-shaped grooves, and the surface of the placement table 205 is coated with an anti-slip coating.

[0030] As mentioned above, a positioning block 2041 is designed at the bottom of the guide block 204 and inserted into the top opening of the base 1 to prevent the guide block 204 from shaking during the working process and improve the stability of the device. Four T-shaped grooves are opened inside the guide block 204 to allow the slide bar 202 and the slide plate 2021 to slide inside the T-shaped grooves, thereby achieving a limiting effect. An anti-slip coating is applied to the surface of the placement table 205 to ensure stability and prevent sliding when placing products.

The slide bar 202 and the bottom slide plate 2021 then slide horizontally inside the T-shaped slide groove of the guide block 204, and the surrounding clamping blocks 203 move outward accordingly. Turn off the motor 5, place the fire damper on the placement table 205 with a protective coating, and then start the motor 5 to drive the rotating plate 201 to rotate counterclockwise, and the mechanism movement belt The movable clamping block 203 moves inward and rotates to clamp the fire damper around the clamping blocks 203. Then the control panel is used to control the sliding telescopic rod 302 to slide inside the annular electromagnetic slide rail 301. The sliding telescopic rod 302 drives each connection assembly to rotate for position adjustment. The position adjustment is controlled by controlling the adjusting rod 203.
