[0023] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described.

[0024] As Figures 1-3 shown, a welding tool for a metal junction box includes a frame body 41 and a welding plate 42 that cooperates with the frame body 41, and further includes:

[0025] A base plate 1, on which a bracket 2 is provided;

[0026] A support unit 5, which is arranged on the base plate 1, and the unit includes a support disc 51, and the support disc 51 supports the welding plate 42;

[0027] A clamping unit 3, which is arranged on the bracket 2 and is on the same axis as the support disc 51. The clamping unit 3 includes a support block 31, a screw 39, and slide blocks 34 symmetrically arranged on the screw 39. A first push block 33 is arranged on the slide block 34;

[0028] A shaping block and an inclined block 38 that cooperates with the slide block 34 are sequentially slidably connected on the support disc 51. A first spring 37 that pushes the shaping block is arranged on the inclined block 38 in a linear array. A second push block 36 is arranged on the shaping block. The screw 39 rotates to drive the slide block 34 to push the inclined block 38 to slide, so that the first push block 33 and the second push block 36 are attached to the inner wall of the frame body 41.

[0029] Specifically, the frame body 41 is a thin-walled square frame body 41, and both the welding plate 42 and the frame body are metal parts. A bracket 2 is provided on the bottom plate 1, and the support unit 5 is arranged on the bottom plate 1. The unit includes a support disk 51 that supports the welding plate 42. The clamping unit 3 is arranged on the bracket 2 and is on the same axis as the support disk 51. The clamping unit 3 includes a support block 31, a screw 39, and sliders 34 symmetrically arranged on the screw 39. A first push block 33 is arranged on the slider 34. A shaping block and an inclined block 38 that cooperates with the slider 34 are sequentially and slidably connected on the support disk 51. A first spring 37 that pushes the shaping block is arranged on the inclined block 38 in a linear array. A second push block 36 is arranged on the shaping block. The screw 39 rotates to drive the slider 34 to push the inclined block 38 to slide, so that the first push block 33 and the second push block 36 are attached to the inner wall of the frame body 41. By rotating the screw 39, the two sliders 34 are driven to slide towards each other, controlling the first push block 33 to be attached to one side inner wall of the frame body 41. During the sliding of the slider 34, through the fitting of the first inclined portion 341 and the second inclined portion 381, the inclined block 38 is driven to push the second push block 36 on the shaping block 35 to be attached to the other side inner wall through the first spring 37, keeping the frame body 41 square, reducing the phenomenon that its shape deforms during welding, resulting in unstable welding. When the welding plate 42 is fixed to the support disk 51, the welding plate 42 is aligned and attached to the frame body 41. Workers can hold the welding gun and rotate the turntable 52 to pre-weld the connection between the frame body 41 and the welding plate 42, and then control the clamping unit 3 to rotate uniformly along the edge to weld the frame body 41, improving the welding efficiency and quality.

[0030] As a further embodiment provided by the present utility model, a first inclined portion 341 is arranged on the slider 34, and a second inclined portion 381 that cooperates with the first inclined portion 341 is arranged on the inclined block 38. There is a raised block on the first inclined portion 341, and a chute that cooperates with the raised block is provided on the second inclined portion 381. When the slider 34 runs and supports, the second inclined portion 381 is pushed by the first inclined portion 341 to make the shaping block 35 slide outwards. When the slider 34 retracts, the raised block drives the chute to make the inclined block 38 return to its initial position.

[0031] As a further embodiment provided by the present utility model, contact blocks 30 are arranged on both the first push block 33 and the second push block 36. The contact blocks 30 cooperate with the frame body 41. The contact blocks 30 increase the contact area of the clamping unit 3 with the frame body 41, further improving the clamping stability.

[0032] As a further embodiment provided by the present utility model, the support unit 5 includes a first rotating wheel 54, a second rotating wheel 56, and a driving rod 55 disposed at the axis of the second rotating wheel 56. A push plate 57 is threadedly connected to the driving rod 55. The first rotating wheel is rotatably connected to the bottom plate 1 and meshes with the second rotating wheel. A rotating disc 52 is rotatably disposed on the support disc 51. A second spring 53 is circumferentially arranged between the rotating disc 52 and the push plate 57. A guiding column is disposed at the axis of the second spring 53. One end of the guiding column is fixed to the rotating disc 52, and the other end thereof is slidably connected to the push plate 57. By rotating the first rotating wheel 54 to mesh with the second rotating wheel 56, the driving rod 55 is rotated, causing the push plate 57 to slide upward on the support disc 51. Thus, the welding plate 42 on the support disc 51 is pushed by the second spring 53 to contact the frame 41. The higher the push plate 57 slides upward, the greater the pressing force of the welding plate 42 on the frame 41 by the second spring 53. When the push plate 57 slides upward, the guiding column will rise through the push plate 57 along with the push plate 57.

[0033] As a further embodiment provided by the present utility model, a locking member 511 is disposed on the support disc 51. The locking member 511 is a magnetic sheet, which is circumferentially arranged on the support disc 51 and at least four of them are provided. The welding plate 42 is adsorbed by the magnetic sheet to fix the cooperation between the support plate and the frame 41.

[0034] As a further embodiment provided by the present utility model, a chuck 32 rotatably connected to the bracket 2 is disposed on the support block 31. A motor 21 is disposed at the axis of the chuck 32. The motor 21 is fixed to the bracket 2, and the model of the motor 21 is MHMF042L1U2M2. The rotation of the frame 41 can be controlled by the motor 21 when it fits the welding plate 42, so as to improve the welding speed and quality.

[0035] As a further embodiment provided by the present utility model, square grooves 510 are circumferentially arranged on the support disc 51. The grooves 510 are square grooves 510, which increases the contact area with the hand and the friction effect.

[0036] As a further embodiment provided by the present utility model, reinforcing ribs are disposed on the bracket 2. The reinforcing ribs are symmetrically arranged on the bracket 2 in a triangular structure, which improves the supporting effect of the bracket 2 on the clamping unit 3 and makes the device more stable during operation.

[0037] Working principle: First, fold the frame body 41 in half to form a square shape, and fit it onto the two first pushing blocks 33. Then rotate the screw rod 39 to make the two sliders 34 slide relative to each other, so that the first pushing blocks 33 fit against the inner wall of the frame body 41, improving the supporting effect on the frame body 41. At the same time, when the sliders 34 slide, they will push the inclined block 38 to slide through the first inclined portion 341, and contact the inner wall of the frame body 41 by the elastic force of the first spring 37 against the second pushing block 36 of the shaping block 35, thereby improving the shaping effect on the frame body 41. Fix the welding plate 42 to the support plate 51, rotate the first rotating wheel 54 to drive the second rotating wheel 56 to rotate, synchronously drive the driving rod 55 to rotate to control the pushing plate 57 to slide upward, and push the welding plate 42 on the support plate 51 to contact the frame body 41 through the second spring 53, so that the corners of the frame body 41 and the welding plate 42 are fitted, improving the subsequent welding effect.
