[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 — Figure 5 As shown, a cabinet door welding clamping tool comprises a base 1, a placing mechanism 2 is connected to the top of the base 1 by bolts, a loading mechanism 3 is arranged on the top of the placing mechanism 2, a conveying mechanism 4 is fixedly installed on the top of the base 1, a positioning mechanism 5 is installed on the conveying mechanism 4, and a welding assembly 101 is connected to the top of the rear side of the base 1 by bolts. When the conveying mechanism 4 brings the cabinet door to be welded into the position of the welding assembly 101, the welding assembly 101 performs welding work on the welding part of the cabinet door.

[0025] In this embodiment, the placement mechanism 2 includes a material discharge box 201, which is connected to the top of the base 1 by bolts. A material discharge trough 202 is opened on the top of the material discharge box 201, and a positioning mark 203 is set at the center position of the inner wall at the bottom of the material discharge trough 202. Before welding, the staff puts the stacked cabinet door parts to be welded into the material discharge trough 202, so that the center position of the welded parts is aligned with the positioning mark 203, which is convenient for automatic clamping.

[0026] In this embodiment, the loading mechanism 3 includes a mounting frame 301, which is connected to the discharge box 201 and the top of the No. 2 electric guide rail 401 by bolts, and the bottom of the mounting frame 301 is connected to the No. 1 electric guide rail 302 by bolts. A mobile cylinder 303 is slidably connected inside the No. 1 electric guide rail 302, and a suction cup 304 is connected to the output end of the mobile cylinder 303 by bolts.

[0027] In this embodiment, the conveying mechanism 4 includes a No. 2 electric guide rail 401, in which two upper and lower movable plates 402 are slidably installed, a plurality of mounting grooves 403 are provided on the top of the movable plates 402, a plurality of rotary clamping cylinders 404 are connected to the mounting grooves 403 by bolts, and a center groove 405 is provided in the middle position of the top of the No. 2 electric guide rail 401. When welding is in progress, the two movable plates 402 are staggered front and back, and the two movable plates 402 will not interfere with each other.

[0028] In this embodiment, the positioning mechanism 5 includes a first limiting rod 501 for limiting the cabinet door, the first limiting rod 501 is connected to the top of the movable plate 402 by bolts, the first limiting rod 501 is internally threadedly connected to a first bidirectional screw rod 502, the first bidirectional screw rod 502 is rotatably connected in the center groove 405, a center positioning block 504 is welded at the middle position of the first bidirectional screw rod 502, two symmetrically arranged sliding grooves 503 are opened in the first limiting rod 501, a second limiting rod 505 is slidably connected in the sliding groove 503, and one end of the second limiting rod 505 is threadedly connected to a second bidirectional screw rod 50 6. One end of the No. 1 electric guide rail 302 is located directly above the positioning mark 203, and the other end of the No. 1 electric guide rail 302 is located directly above the center positioning block 504. When the suction cup 304 is picking up and loading materials, the mobile cylinder 303 moves to one end of the No. 1 electric guide rail 302. At this time, the suction cup 304 is located directly above the positioning mark 203. The suction cup 304 can suck the welded parts in the discharge trough 202, thereby moving the welded parts to the top of the movable plate 402 and clamping them between the first limit rod 501 and the second limit rod 505 to realize automatic loading, and can limit the horizontal direction of the welded parts.

[0029] Working principle: Before using the device, the staff first puts the stacked cabinet door parts to be welded into the discharge trough 202, aligns the center position of the welded parts with the positioning mark 203, and rotates the first two-way screw rod 502 and the second two-way screw rod 506 to make the rectangular area surrounded by the first limit rod 501 and the second limit rod 505 consistent with the outer contour of the cabinet door welded parts. When welding, first start the No. 1 electric guide rail 302 to bring the moving cylinder 303 to the front end. At this time, the suction cup 304 is located directly above the positioning mark 203. , the moving cylinder 303 pushes the suction cup 304 to extend, the suction cup 304 sucks the center position of the weldment and lifts it, the No. 1 electric guide rail 302 moves the weldment to the top position of the moving plate 402, the suction cup 304 is now aligned with the center positioning block 504, and then the suction cup 304 is pushed out, so that the weldment is just aligned with the rectangular area surrounded by the first limiting rod 501 and the second limiting rod 505, the weldment is limited in the horizontal direction, and then the rotary clamping cylinder 404 is pressed on the top of the weldment, driving the No. 2 electric guide rail 40 1, the second electric guide rail 401 drives a moving plate 402 to move into the welding assembly 101 for welding. The two moving plates 402 can only enter the welding assembly 101 position individually. When one moving plate 402 enters the welding assembly 101, the other moving plate 402 will move out from the inside of the welding assembly 101. While one set of moving plates 402 is welding with the welded parts, the other moving plate 402 is performing the loading and unloading process. After the welding is completed, the moving plate 402 is taken out of the welding assembly 101 with the welded parts. 1, the rotary clamping cylinder 404 releases the pressure on the welded part, the suction cup 304 takes out the welded workpiece and moves it to the front, the staff removes the workpiece, the suction cup 304 immediately takes the material for the next time, puts the new welded part on the top of the empty moving plate 402, and waits for the moving plate 402 with the welded part to be moved out of the welding assembly 101, and then moves the welded part out. In this way, the processing efficiency can be accelerated, and automatic loading is realized, and it can adapt to cabinet door welded parts of various sizes, with strong practicality.
