A refrigeration and conveying mechanism is arranged on the electric lifting cylinder 101. The refrigeration and conveying mechanism is used to circulate, refrigerate, and convey the coolant; the bottom wall of the inner bottom of the placement groove 202 is made of a material with good thermal conductivity. When a low-temperature coolant circulates in the inner cavity of the water flow channel 401, the two welded plate-shaped fittings can be quickly cooled by heat transfer; Further, a horizontal base 103 is arranged at the bottom of the mounting bracket 100. Fixed plates 104 are symmetrically and fixedly arranged on both sides of the base 103. Bolts 105 are screwed on the fixed plates 104; the bolts 105 provided facilitate the fixed installation of the device at the required installation site.

[0024] Embodiment 2, on the basis of Embodiment 1, the two plate-shaped fittings are stacked and placed in the inner bottom of the placement groove 202, and the width of the inner bottom of the placement groove 202 is the same as the width of the two plate-shaped fittings; the two plate-shaped fittings to be welded are sequentially placed in the inner bottom of the placement groove 202, and the two are stacked. Since the width of the inner bottom of the placement groove 202 is the same as the width of the two plate-shaped fittings, the two sides of the two plate-shaped fittings are attached to the left and right sides of the inner bottom of the placement groove 202, making the left and right sides of the two plate-shaped fittings aligned, which is beneficial for subsequent welding; Further, the clamping mechanism includes a sliding rod 203 that penetrates through the front side wall of the placement rack 201. The sliding rod 203 slides along the length direction of the placement groove 202. The rear end of the sliding rod 203 is located inside the placement groove 202 and is provided with a side pressing plate 204. The side wall of the side pressing plate 204 is arranged parallel to the rear side wall of the placement groove 202. When the sliding rod 203 and the side pressing plate 204 are pushed, the two plate-shaped fittings can be respectively abutted against the side wall of the side pressing plate 204 and the rear side wall of the placement groove 202 before and after, so that the two plate-shaped fittings are clamped and fixed. Further, a plurality of first springs 205 are fixedly arranged between the front side wall of the side pressing plate 204 and the front side wall inside the placement groove 202. The plurality of first springs 205 are arranged at equal intervals, and the telescopic direction of the first springs 205 is the same as the sliding direction of the sliding rod 203. The sliding rod 203 is located at the central position of the placement groove 202. The first springs 205 are arranged in an odd number. The rod body of the sliding rod 203 passes through the inside of the first spring 205 located in the middle at intervals. A pull rod 206 is arranged at the front end of the sliding rod 203. An anti-slip sleeve 207 is fixedly sleeved on the rod body of the pull rod 206. Leakage openings 208 are formed on the left and right sides of the placement rack 201. The leakage openings 208 expose the sides of the two plate-shaped fittings. Before the two plate-shaped fittings are placed into the placement groove 202, the sliding rod 203 and the side pressing plate 204 are pulled through the pull rod 206, so as to expand the distance between the rear side of the side pressing plate 204 and the rear side inside the placement groove 202. At this time, all the first springs 205 are compressed. Then the two plate-shaped fittings are placed into the placement groove 202. After the pull rod 206 is released, the compressed first springs 205 will push the side pressing plate 204 to move, so as to clamp the front and rear sides of the two plate-shaped fittings between the rear side of the side pressing plate 204 and the rear side inside the placement groove 202, that is, the two plate-shaped fittings can be clamped and fixed. Since the first springs 205 are arranged in an odd number, and the rod body of the sliding rod 203 passes through the inside of the first spring 205 located in the middle at intervals with the sliding rod 203 being located at the central position of the placement groove 202, when the sliding rod 203 pulls the side pressing plate 204, the thrust of the first springs 205 received by the side pressing plate 204 is relatively uniform. After the pull rod 206 is released, the plurality of first springs 205 will also push the side pressing plate 204 to move evenly after being released, so that the force of the side pressing plate 204 pressing the plate-shaped fittings is more uniform. After the sides of the two plate-shaped fittings are attached, the positions to be welded are exposed at the leakage openings 208, which is convenient for the subsequent welding head 305 to weld them.

"T"-shaped sliding blocks 312 are symmetrically and fixedly protruded at the top of the connecting plate 311. The sliding blocks 312 are adaptively and slidably clamped into the slots of the sliding grooves 310.

The rod body of the screw rod 317 is screwed to the center of the top of the mounting block 303. A knob 318 is fixedly arranged at the top end of the screw rod 317. When it is necessary to appropriately adjust the height of the welding head 305 according to the positions of the sides of the two plate-shaped fittings, the user can drive the screw rod 317 to rotate through the knob 318 before welding, so that the mounting block 303 slides along the inside of the lifting groove 316. Further, a bracket 319 is rotatably arranged at one end of the mounting plate 302 away from the mounting block 303. The top of the bracket 319 is fixed to the bottom of the connecting plate 311. A damping shock absorber 320 is arranged between the top of the mounting plate 302 away from the bracket 319 and the connecting plate 311.

The third spring 323 is telescopically arranged in the same direction as the damping telescopic rod 321, and the rod body of the damping telescopic rod 321 passes through the inside of the middle first spring 323 with a gap left. When the mounting plate 302 is pressed down to touch the upper plate-shaped fitting, the mounting plate 302 can be appropriately shock-absorbed through the damping shock absorber 320, which is beneficial to reducing the influence of the vibration of the mounting plate 302 on the welding head 305.

The industrial water chiller 405 is a water cooling device, which belongs to the existing device. It can provide a cooling device with constant temperature, constant flow and constant pressure. The principle of the industrial water chiller is to inject a certain amount of water into the water tank inside itself, cool the water through the refrigeration system of the industrial water chiller, and then send the low-temperature frozen water into the equipment that needs to be cooled. The cooling water takes away the heat inside the equipment, and the high-temperature hot water flows back to the water tank again for cooling. In this way, the cooling effect is achieved by circulating and exchanging cooling. In this embodiment, after the water is cooled by the industrial water chiller 405, the cooling water is sent into the water flow channel 401 through the delivery pump 406 and the water inlet pipe 409, so as to cool the welded plate-shaped fittings, and the water with a higher temperature returns to the delivery pump 406 again through the water outlet pipe 407 for re-refrigeration; A second protective door 410 for blocking the second installation bin 404 is hinged on the rear side wall of the mounting frame 100.
