Description

Technical Field

Through precise welding technology, it can ensure that the various interfaces of the distribution cabinet are well sealed to prevent the entry of foreign substances such as water vapor and dust, thereby ensuring the normal operation of the electrical components inside the distribution cabinet. Welding equipment can achieve precise welding control, make the welding joints flat and smooth, and improve the overall appearance of the distribution cabinet.

DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-Figure 7 A welding device for a power distribution cabinet comprises a workbench 101, a welding device 102 is provided on the side wall of the workbench 101, a welding table 103 is provided on the workbench 101, a power distribution cabinet 104 is provided on the welding table 103, a containing frame 105 is provided in the workbench 101, a clamping mechanism 300 for clamping and fixing the power distribution cabinet 104 is provided on the welding table 103, a rotating mechanism 200 for driving the welding table 103 to rotate is provided in the workbench 101, an adsorption mechanism 400 and a connecting mechanism 500 for further stabilizing the power distribution cabinet 104 are provided on the clamping mechanism 300, and a stabilizing mechanism 600 is provided on the connecting mechanism 500.

[0025] The clamping mechanism 300, the adsorption mechanism 400 and the stabilizing mechanism 600 are used to clamp and fix the distribution cabinet 104 to prevent it from shifting during rotation and causing welding shift. When welding the frame or corners of the distribution cabinet 104, since the clamping position avoids the welding blind area, the frame or corners of the distribution cabinet 104 can be welded by cooperating with the rotating mechanism 200 and the welding device 102, thereby improving the welding efficiency.

[0026] Reference Figure 2-Figure 3: The clamping mechanism 300 includes a second motor 301, a fixed plate 302, a bidirectional threaded rod 303, a fixed clamping block 304 and a movable clamping plate 305. The fixed plate 302 is fixedly installed on the inner wall of the accommodating frame 105, and the second motor 301 is installed on the fixed plate 302. The output end of the second motor 301 is connected to the bidirectional threaded rod 303. The fixed clamping block 304 is symmetrically fixedly installed on the welding table 103. The other end of the bidirectional threaded rod 303 passes through the fixed clamping block 304. The movable clamping plate 305 is symmetrically slidably provided between the fixed clamping blocks 304. The movable clamping plate 305 is slidably set on the bidirectional threaded rod 303. The movable clamping plate 305 is provided with a thread that cooperates with the bidirectional threaded rod 303. The movable clamping plate 305 is connected to the adsorption mechanism 400 and the connecting mechanism 500.

[0027] The second motor 301 is started to drive the bidirectional threaded rod 303 to rotate. The bidirectional threaded rod 303 cooperates with the movable clamping plate 305 to achieve relative or reverse movement of the movable clamping plate 305, thereby cooperating with the distribution cabinet 104 to clamp, fix and unlock the distribution cabinet 104.

[0028] Reference Figure 4-Figure 5 The adsorption mechanism 400 includes a connecting column 401, a stopper 402, a push block 403, a piston rod 404, a piston 405, a suction cylinder 406, a suction cup 407 and a first return spring 408. One end of the connecting column 401 is connected to the movable clamping plate 305, and the other end of the connecting column 401 is connected to the stopper 402. The suction cylinder 406 is symmetrically fixedly installed on the welding table 103, and a piston 405 is slidably arranged in the suction cylinder 406. A suction cup 407 is provided at one end of 406 close to the power distribution cabinet 104, and the suction cup 407 passes through the welding table 103 and is adsorbed and cooperated with the power distribution cabinet 104. A piston rod 404 is provided at one end of the piston 405 away from the suction cup 407, and the other end of the piston rod 404 passes through the bottom wall of the suction cylinder 406 to connect to the push block 403, and the push block 403 is abutted and cooperated with the abutment block 402, and the two ends of the first return spring 408 are respectively connected to the side wall of the push block 403 and the bottom wall of the suction cylinder 406.

[0029] As the movable clamping plate 305 approaches the distribution cabinet 104, it drives the connecting column 401 to approach the distribution cabinet 104. The connecting column 401 drives the resistance block 402 to push the push block 403, and drives the push block 403 to push the piston rod 404 and the piston 405. The suction cup 407 can provide an adsorption force to the bottom wall of the distribution cabinet 104, thereby improving the stability of the distribution cabinet 104 during rotation. The first reset spring 408 is used to drive the piston rod 404 and the piston 405 to reset for the next adsorption movement.

[0030] Reference Figure 6: The connecting mechanism 500 includes a rack 501, a gear 502, a rotating cylinder 503, a screw 504, a connecting block 505, a sliding column 506 and a support rod 507. The rotating cylinder 503 is rotatably arranged in the movable clamping plate 305. The gear 502 is sleeved on the side wall of the rotating cylinder 503. The rack 501 is installed on the bottom wall of the screw 504. The gear 502 is meshed with the rack 501. The screw 504 is rotatably arranged in the rotating cylinder 503. The rotating cylinder 503 is provided with a thread that cooperates with the screw 504. The other end of the screw 504 is connected to the connecting block 505. The sliding columns 506 are symmetrically arranged on the side wall of the connecting block 505. The sliding columns 506 are slidably matched with the inner wall of the movable clamping plate 305. The connecting block 505 is provided with a support rod 507. The support rod 507 is provided with a stabilizing mechanism 600 at one end away from the gear 502.

[0031] When the movable clamping plate 305 approaches the distribution cabinet 104, it can drive the rotating cylinder 503 to approach the distribution cabinet 104. At this time, the gear 502 slides on the rack 501 to drive the gear 502 to rotate, and the gear 502 drives the rotating cylinder 503 to rotate. The thread in the rotating cylinder 503 cooperates with the screw rod 504 to realize the downward movement of the screw rod 504, the connecting block 505 and the sliding column 506 in the movable clamping plate 305, which can realize the up and down movement of the support rod 507.

[0032] Reference Figure 7 : The stabilizing mechanism 600 includes a connecting rope 601, a mounting plate 602, a support block 603, a stabilizing block 604 and a second return spring 605. The support block 603 is installed on the support rod 507. The support block 603 is rotatably provided with a stabilizing block 604 that abuts against the distribution cabinet 104 on the side close to the distribution cabinet 104. The support block 603 is provided with a mounting plate 602. Both ends of the second return spring 605 are respectively connected to the side wall of the stabilizing block 604 and the bottom wall of the mounting plate 602. One end of the connecting rope 601 is connected to the bottom wall of the stabilizing block 604 close to one end of the support block 603, and the other end of the connecting rope 601 is connected to the welding table 103.

[0033] When the support rod 507 moves downward, the connecting rope 601 is in a loosened state. When the support rod 507 drops to a specified height, the second reset spring 605 drives the stabilizing block 604 to reset and provide a pressing and stabilizing force to the upper end of the distribution cabinet 104. When the support rod 507 rises, that is, when the movable clamping plate 305 releases the distribution cabinet 104, the connecting rope 601 pulls the stabilizing block 604 to gradually unlock the distribution cabinet 104, thereby achieving the overall unlocking of the distribution cabinet 104.

[0034] Reference Figure 4The rotating mechanism 200 includes a first motor 201, a receiving plate 202 and a connecting plate 203. The first motor 201 is installed in the accommodating frame 105. The output end of the first motor 201 is connected to the receiving plate 202. The other end of the receiving plate 202 is symmetrically provided with a connecting plate 203. The other end of the connecting plate 203 is connected to the bottom wall of the welding platform 103.

[0035] The first motor 201 is started to drive the receiving plate 202 and the connecting plate 203 to rotate, and the connecting plate 203 drives the welding table 103 to rotate. The rotation of the welding table 103 can adjust the welding angle of the power distribution cabinet 104, thereby improving the welding efficiency.

[0036] Here’s how it works:

[0037] S1: Place the power distribution cabinet 104 on the welding table 103, with the side of the power distribution cabinet 104 parallel to the movable clamping plate 305, start the second motor 301 to drive the bidirectional threaded rod 303 to rotate, and the movable clamping plate 305 can move relative to or away from each other through the cooperation between the bidirectional threaded rod 303 and the movable clamping plate 305, so that the power distribution cabinet 104 can be clamped, fixed and unlocked;

[0038] S2: When the movable clamping plate 305 approaches the power distribution cabinet 104, it drives the connecting column 401 to approach the power distribution cabinet 104. The connecting column 401 drives the abutting block 402 to push the pushing block 403, and drives the pushing block 403 to push the piston rod 404 and the piston 405. The suction cup 407 can provide an adsorption force to the bottom wall of the power distribution cabinet 104, thereby improving the stability of the power distribution cabinet 104 during rotation. The first reset spring 408 is used to drive the piston rod 404 and the piston 405 to reset for the next adsorption movement;

[0039] S3: The movable clamping plate 305 can drive the rotating cylinder 503 to approach the distribution cabinet 104 during the process of approaching the distribution cabinet 104. At this time, the gear 502 slides on the rack 501 to drive the gear 502 to rotate, and the gear 502 drives the rotating cylinder 503 to rotate. The screw rod 504, the connecting block 505 and the sliding column 506 move downward in the movable clamping plate 305 through the cooperation of the thread in the rotating cylinder 503 and the screw rod 504, so that the support rod 507 can move up and down.

[0040] S4: When the support rod 507 moves downward, the connecting rope 601 is in a loosened state. When the support rod 507 drops to a specified height, the second reset spring 605 drives the stabilizing block 604 to reset and provide a pressing and stabilizing force to the upper end of the power distribution cabinet 104. When the support rod 507 rises, that is, when the movable clamping plate 305 releases the power distribution cabinet 104, the connecting rope 601 pulls the stabilizing block 604 to gradually unlock the power distribution cabinet 104, thereby realizing the overall unlocking of the power distribution cabinet 104.

[0041] S5: After the power distribution cabinet 104 is clamped, fixed, the top is pressed, and the bottom wall is adsorbed, the first motor 201 is started to drive the receiving plate 202 and the connecting plate 203 to rotate, and the connecting plate 203 drives the welding table 103 to rotate. The rotation of the welding table 103 can adjust the welding angle of the power distribution cabinet 104. The welding table 103 rotates to a position that cooperates with the welding device 102 and stops. The welding device 102 is started to weld the power distribution cabinet 104. After the frame or corner welding on one side of the power distribution cabinet 104 is completed, the first motor 201 is started again to drive the welding table 103 to rotate to a specified position to weld the frame or corner on the other end of the power distribution cabinet 104. This improves the stability of the power distribution cabinet 104 during rotation, reduces the possibility of offset, improves the accuracy of welding, improves the efficiency of welding, and the clamping position avoids the welding blind area. In this way, by starting the first motor 201 and continuously adjusting the angle of the welding table 103, the power distribution cabinet 104 can be welded in all directions;

[0042] S6: After welding is completed, the second motor 301 is started to drive the movable clamping plate 305 to unlock the distribution cabinet 104. In the process that the movable clamping plate 305 continues to move away from the distribution cabinet 104, the first reset spring 408 drives the piston rod 404 and the piston 405 to reset, so that the distribution cabinet 104 and the suction cup 407 are unlocked, the support rod 507 rises, and the connecting rope 601 pulls the stabilizing block 604 to gradually unlock the distribution cabinet 104. In this way, the overall unlocking of the distribution cabinet 104 can be achieved, and then the distribution cabinet 104 after welding is removed and a new distribution cabinet 104 that needs to be welded is placed.

[0043] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
