Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a welding auxiliary device. Background Art

[0002] In the electrical industry, high-voltage, medium-voltage, and low-voltage circuit breakers all contain flexible connectors and moving contact assemblies. The moving contact controls the circuit breaker's opening and closing functions, and its performance directly impacts the breaker's quality and service life. The flexible connector connects the moving contact to the coil, ensuring both smooth movement and smooth circuit flow. Welding is required between the moving contact and the flexible connector to ensure a stable connection.

[0063] Reference Figures 1 to 8 As shown, this embodiment provides a welding auxiliary device for assisting a welder in welding a product assembly 110 .

[0064] Specifically, the product assembly 110 includes a moving contact 111 and a flexible connection 112. The welding machine is correspondingly provided with a first welding head 121 and a second welding head 122. The moving contact 111 and the flexible connection 112 can be placed between the first welding head 121 and the second welding head 122. Furthermore, the moving contact 111 is provided with a positioning groove 1111, and the flexible connection 112 is provided with a welding portion, which is placed in the positioning groove 1111.

[0065] Specifically, the welding auxiliary device includes a base assembly 200 , a first clamping mechanism 300 , a second clamping mechanism 400 and a blanking mechanism 500 , wherein the first clamping mechanism 300 , the second clamping mechanism 400 and the blanking mechanism 500 are all disposed on the base assembly 200 .

[0066] Specifically, the first clamping mechanism 300 includes a clamp assembly 310 for securing the movable contact 111 and an elastic body 320 connected to the clamp assembly 310. The clamp assembly 310 can be moved between an initial position and a welding position via the elastic body 320. The initial position refers to the position of the product assembly 110 to be welded when it is not subjected to the action of the first welding head 121, and the welding position refers to the position where the product assembly 110 contacts the second welding head 122. In this embodiment, the first welding head 121 can move toward the base assembly 200 and push the product assembly 110 against it, causing the clamp assembly 310 to move from the initial position toward the base assembly 200 to the welding position. When the clamp assembly 310 is in the welding position, the movable contact 111 contacts the second welding head 122. It is worth noting that the elastic body 320 can restore the clamp assembly 310 from the welding position to the initial position, preventing the movable contact 111 from sticking and affecting subsequent operations.

[0067] Specifically, the second clamping mechanism 400 is disposed on the base assembly 200 and includes a first fixing clamp 410 and a second fixing clamp 420, which are correspondingly disposed. The first fixing clamp 410 and the second fixing clamp 420 are used to clamp and straighten the flexible coupling 112. In this embodiment, the first fixing clamp 410 and the second fixing clamp 420 can respectively clamp and fix the two ends of the flexible coupling 112, and the first fixing clamp 410 can move away from the second fixing clamp 420, thereby straightening the flexible coupling 112.

[0068] Specifically, the unloading mechanism 500 can transfer the welded product assembly 110 to the unloading position.

[0069] In this embodiment, first, the movable contact 111 is fixed by the clamp assembly 310, and the soft connection 112 is fixed and straightened by the first fixing clamp 410 and the second fixing clamp 420, so that the movable contact 111 and the soft connection 112 have a high welding positioning accuracy; secondly, the first welding head 121 moves toward the base assembly 200 and pushes the product assembly 110 to move the clamp assembly 310 to the welding position, thereby making the movable contact 111 abut against the second welding head 122, effectively avoiding the situation where the movable contact 111 is welded in the air and affecting the welding quality, thereby achieving The weld joint is firm and meets the requirements of mechanical testing; again, after welding is completed, the first welding head 121 returns to its original position, and the clamp assembly 310 moves to its initial position under the action of the elastic body 320. At this time, the moving contact 111 and the second welding head 122 are completely separated, thereby effectively preventing the moving contact 111 from adhering to the second welding head 122 and avoiding affecting subsequent process operations; finally, the clamp assembly 310, the first fixing clamp 410 and the second fixing clamp 420 release the product assembly 110, and the welded product assembly 110 is transferred to the unloading position through the unloading mechanism 500. During the entire operation, the safety of the operator can be effectively guaranteed. The welding auxiliary device can effectively improve the positioning accuracy of the soft connection 112 and the moving contact 111, and can improve the welding efficiency and quality of the product assembly 110, further realizing the automated welding of the moving contact 111 and the soft connection 112.

[0070] In this embodiment, referring to Figures 3 to 5 As shown, the first clamping mechanism 300 further includes a support block 330, a floating block 340, a limiting plate 350, and a limiting block 360.

The limiting plate 350 can abut against the support block 330 to limit the movement of the floating block 340 toward the base assembly 200; and the limiting block 360 is fixedly connected to the support block 330 and abut against the limiting plate 350 to limit the movement of the floating block 340 away from the base assembly 200. In this embodiment, the floating block 340 slides on the support block 330 to enable stable directional movement of the clamp assembly 310 and the product assembly 110 mounted thereon. The design of the limit plate 350 and the limit block 360 allows the floating block 340 to slide back and forth within a limited range, thereby enabling the clamp assembly 310 to accurately transition between the initial position and the welding position, effectively preventing excessive movement of the clamp assembly 310 and the product assembly 110 mounted thereon from affecting welding quality.

[0083] Specifically, the baffle 421 is disposed on one of the side arms of the second fixing clip 420 .

[0084] In this embodiment, referring to Figure 7 As shown, the blanking mechanism 500 includes a fixed block 510, a third telescopic device 520, and a push plate assembly 530. The fixed block 510 is disposed on the base assembly 200, the fixed end of the third telescopic device 520 is fixedly connected to the fixed block 510, and the push plate assembly 530 is connected to the telescopic end of the third telescopic device 520. The third telescopic device 520 can drive the push plate assembly 530 to move to push the transferred welded product assembly 110, that is, to push the product assembly 110 away from the second welding head 122. The blanking mechanism 500 has a simple structure, facilitates the transfer of the product assembly 110, and improves blanking efficiency.

[0085] Preferably, the third telescopic device 520 is a cylinder. Of course, the third telescopic device 520 can also be other devices, which will not be further limited here.

[0086] In addition, the push plate assembly 530 includes a fixed push plate 531 connected to the telescopic end of the third telescopic device 520 and a positioning push plate 532 installed on the fixed push plate 531. The positioning push plate 532 can adjust its position in the vertical direction.

[0087] Specifically, a positioning slot 5311 extending in the vertical direction is provided on one side of the fixed push plate 531, and a positioning protrusion 5321 is provided on the adjusting push plate 532.

[0091] Furthermore, the second pushing portion 5322 is arranged closer to the soft connection 112 than the first pushing portion 5312. In this embodiment, when the clamp assembly 310 releases the moving contact 111, the first clamping head 312 disengages from the moving contact 111, but the moving contact 111 is still in close contact with the second clamping head 343. The second pushing portion 5322 first contacts the second end of the soft connection 112, causing the moving contact 111 to deflect so that the moving contact 111 disengages from the second clamping head 343. Thereafter, the first pushing portion 5312 contacts the first end of the soft connection 112 and pushes the soft connection 112 together with the second pushing portion 5322, effectively preventing a jam between the product assembly 110 and the second clamping head 343 during the blanking process, which could hinder blanking.

[0092] In this embodiment, the unloading mechanism 500 also includes a unloading slide 540 arranged on the opposite side of the push plate assembly 530. The push plate assembly 530 can push the product component 110 onto the unloading slide 540, and the product component 110 can slide along the unloading slide 540 to the unloading position to prevent the hot product component 110 after welding from hitting the air pipes connected to various pneumatic devices, causing damage to the air pipes.
