The bidirectional threaded rod extends forward and passes through the interior of a fixed box. The extended part of the bidirectional threaded rod is fixedly connected to a ratchet, and one side of the ratchet is meshed with a rotatable ratchet. By placing the electrical cabinet on the bottom surface of the fixed box, and then rotating the bidirectional threaded rod clockwise, the two moving blocks are driven to move toward each other, and the two clamping plates are driven to clamp the electrical cabinet; when the bidirectional threaded rod rotates clockwise, the protruding part of the surface of the ratchet contacts the ratchet, driving the ratchet and the rotating rod to flip, and at the same time driving the vortex spring to deform, and then the vortex spring rebounds to drive the rotating rod and the ratchet to reverse and return to the original position. When the bidirectional threaded rod rotates counterclockwise, the concave part of the ratchet is against the ratchet, thereby limiting the rotation of the ratchet. The cooperation of the above structure achieves a limiting effect on the clamping of the positioning device, preventing the occurrence of unstable clamping.

Description

Technical Field

[0001] The utility model relates to the technical field of electric welding equipment, in particular to a welding equipment for processing electric cabinets to prevent splashing. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. The electrical cabinet shell needs to be welded with steel plates during production, and electrical cabinet shell welding equipment is required during the welding process.

[0003] A Chinese patent discloses an electrical cabinet shell welding device with a publication number of CN218081050U, and the application date is 2022.08.03. The patented technology can limit the steel plate during the pushing process by setting a fixed guide plate and an adjustable guide plate. At the same time, the adjustment mechanism of the device can adjust the position of the adjustable guide plate to avoid the steel plate from offset during welding. However, the above device drives the guide plate to move to limit the electrical cabinet by rotating the adjusting screw rod, but does not limit the adjusting screw rod. Then the adjusting screw rod may rotate naturally during the processing of the electrical cabinet, thereby driving the guide plate to move and losing the effect of limiting the electrical cabinet. Therefore, the inventor provides a spatter-proof welding device for electrical cabinet processing to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to provide a splash-proof welding device for processing an electrical cabinet, which can prevent sparks from splashing during electric welding and stably clamp and fix the electrical cabinet.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A spatter-proof welding device for processing electrical cabinets comprises a base, a fixed box is fixedly connected to the top of the base, a placement plate is fixedly connected to the left side of the front face of the fixed box, a welding gun is placed on the top of the placement plate, two-way threaded rods are rotatably connected to the front and rear sides of the interior of the fixed box, a pair of mirror-symmetrical moving blocks are threadedly connected to the front and rear sides of the two-way threaded rods, connecting rods are respectively fixedly connected to the left and right sides of the top of the moving blocks, and a clamping plate is fixedly connected to the top of the connecting rods; the two-way threaded rod extends forward to pass through the interior of the fixed box, a ratchet is fixedly connected to a part of the surface of the extended two-way threaded rod, and a rotatable ratchet is meshed on one side of the ratchet.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The electrical cabinet is processed with a spatter-proof welding device. The electrical cabinet is placed on the top surface of a fixed box, and then the bidirectional threaded rod is rotated clockwise, thereby driving the two moving blocks to move toward each other, thereby driving the two clamping plates to move toward each other and clamp the surface of the electrical cabinet. When the bidirectional threaded rod rotates clockwise, the protruding part of the surface of the ratchet contacts the ratchet teeth, driving the ratchet teeth and the rotating rod to flip upward, while driving the vortex spring to deform, and when the protruding part passes over, the vortex spring rebounds and drives the rotating rod and the ratchet teeth to reverse and return to their original positions.

When the support rod is pulled backward, the support rod drives the driving rod to slide forward along the guide groove, driving the arc cover plate to move downward and flip. This can cover the splash of sparks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1 , 3 As shown, a spatter-proof welding equipment for processing electrical cabinets comprises a base 10, a fixed box 20 is fixedly connected to the top of the base 10, and a bidirectional threaded rod 21 is rotatably connected to the front and rear sides of the interior of the fixed box 20, and a pair of mirror-symmetrical moving blocks 22 are threadedly connected to the front and rear sides of the bidirectional threaded rod 21, and the top left and right sides of the moving blocks 22 are respectively fixedly connected with connecting rods 23; a pair of moving grooves 24 are respectively provided on the front and rear sides of the top of the fixed box 20, and the corresponding connecting rods 23 are slidably connected to the corresponding moving grooves 24, and a clamping plate 25 is fixedly connected to the top of the inner ends of the pair of connecting rods 23 on the same side.

[0022] When in use, the electrical cabinet is placed on the bottom surface of the fixed box 20, and then the bidirectional threaded rod 21 is rotated clockwise, thereby driving the two moving blocks 22 to move toward each other, thereby driving the two clamping plates 25 to move toward each other and clamp the surface of the electrical cabinet, thereby preventing the electrical cabinet from shifting during welding. At the same time, the movement of the moving block 22 drives the connecting rod 23 to slide along the inside of the moving groove 24, thereby achieving the effect of guiding the movement of the clamping plate 25.

[0023] refer to Figure 2 , 4 The bidirectional threaded rod 21 extends forward and passes through the interior of the fixed box 20, and a ratchet 30 is fixedly connected to the surface of the extended part of the bidirectional threaded rod 21; the front of the fixed box 20 is rotatably connected to a rotating rod 31, and a ratchet 32 ​​is fixedly connected to the surface of the rotating rod 31, and the ratchet 32 ​​is meshed with the ratchet 30. A fixing ring 33 is provided on the outer side of the rotating rod 31, and the rear side of the fixing ring 33 is fixedly connected to the surface of the fixed box 20. A spiral spring 34 is provided inside the fixing ring 33, and the outer side of the spiral spring 34 is fixedly connected to the fixing ring 33, and the inner side of the spiral spring 34 is fixedly connected to the surface of the rotating rod 31.

[0024] When the bidirectional threaded rod 21 rotates clockwise, the protruding part of the surface of the ratchet 30 contacts the ratchet 32, driving the ratchet 32 ​​and the rotating rod 31 to flip upward, and at the same time driving the spiral spring 34 to deform. When the protruding part passes over, the spiral spring 34 rebounds and drives the rotating rod 31 and the ratchet 32 ​​to reverse and return to their original positions. When the bidirectional threaded rod 21 rotates counterclockwise, the concave part of the ratchet 30 contacts the ratchet 32, thereby limiting the rotation of the ratchet 30. Thus, the effect of only allowing the two clamping plates 25 to move toward each other during operation is achieved. When the electrical cabinet is welded and finally taken out, the ratchet 32 ​​is first flipped upward to disengage the ratchet 32 ​​from the surface of the ratchet 30, so that the bidirectional threaded rod 21 can rotate freely.

[0025] refer to Figure 2 A placement plate 40 is fixedly connected to the left side of the front of the fixed box 20, and a welding gun 41 is placed on the top of the placement plate 40. When in use, the staff holds the welding gun 41 to weld the electrical cabinet.

[0026] When the welding gun 41 is welding with the electrical cabinet, sparks will splash outwards, and the sparks will affect the normal welding of the workers. At the same time, the sparks will damage the clothes when they come into contact with the clothes. Therefore, a mechanism to prevent sparks from splashing is needed.

[0027] refer to Figure 1 , 25. A pair of mirror-symmetrical support plates 50 are fixedly connected to the left and right sides of the top front end of the fixed box 20. The opposite sides of the two support plates 50 are provided with arc grooves 51. The insides of the two arc grooves 51 are slidably connected with sliding plates 52. The opposite sides of the two sliding plates 52 are fixedly connected with arc-shaped cover plates 53. The arc-shaped cover plates 53 are made of transparent plastic. When welding the electrical cabinet, the arc-shaped cover plate 53 can be slid according to the welding position. When welding the top of the electrical cabinet, the top of the arc-shaped cover plate 53 can be slid upwards. The arc-shaped cover plate 53 will block the sputtering sparks. Similarly, when welding the front of the electrical cabinet, the arc-shaped cover plate 53 can be slid downwards. The arc-shaped cover plate 53 made of transparent material does not affect the staff's observation of the welding position. The shielding plate used in the previous invention is designed as a straight plate and can only move up and down when moving. However, the present device adopts an arc-shaped shielding plate 53 and an arc-shaped moving track. When in use, it can not only cover a larger area of ​​sparks, but also be more adaptable to the welding position of the electrical cabinet when moving. For example, a straight shielding plate is difficult to cover the welding on the top of the electrical cabinet, while the arc-shaped shielding plate 53 can cover the top of the electrical cabinet after sliding upward.

[0028] Specifically, a guide groove 54 is provided inside the arc groove 51, and a driving rod 55 is slidably connected inside the guide groove 54. The right side of the driving rod 55 is fixedly connected to the sliding plate 52, and the left side of the driving rod 55 is rotatably connected to the support rod 56. When in use, the staff can hold the welding gun 41 with the right hand and push the support rod 56 with the left hand to control the position of the arc cover plate 53. When the support rod 56 is pushed forward, the support rod 56 drives the driving rod 55 to slide backward along the guide groove 54, driving the arc cover plate 53 to move upward and flip. When the support rod 56 is pulled backward, the support rod 56 drives the driving rod 55 to slide forward along the guide groove 54, driving the arc cover plate 53 to move downward and flip.

[0029] Preferably, a positioning block 57 is fixedly connected to the front of the support plate 50, and a group of support blocks 58 are fixedly connected to the outer side of the positioning block 57. When in use, it is too tiring to hold up the support rod 56 with hands all the time, and the front end of the support rod 56 can be placed against the top of a certain support block 58 to support the support rod 56, thereby fixing the position of the arc-shaped cover plate 53. Different support blocks 58 support the support rod 56, which also achieves the effect of changing the position of the arc-shaped cover plate 53.

[0030] The working principle of the utility model is: place the electrical cabinet on the top surface of the fixed box 20, and then rotate the bidirectional threaded rod 21 clockwise, so as to drive the two moving blocks 22 to move toward each other, thereby driving the two clamping plates 25 to move toward each other and clamp the surface of the electrical cabinet, thereby preventing the electrical cabinet from deflecting during welding, and at the same time, the moving block 22 moves to drive the connecting rod 23 to slide along the inside of the moving groove 24, thereby achieving the effect of guiding the movement of the clamping plates 25. When the bidirectional threaded rod 21 rotates clockwise, the protruding part of the surface of the ratchet 30 contacts the ratchet 32, driving the ratchet 32 ​​and the rotating rod 31 to flip upward, and at the same time driving the volute spring 34 to deform, and when the protruding part passes over, the volute spring 34 rebounds and drives the rotating rod 31 and the ratchet 32 ​​to reverse and return to the original position. When the bidirectional threaded rod 21 rotates counterclockwise, the concave part of the ratchet 30 abuts against the ratchet 32, thereby limiting the rotation of the ratchet 30. Thus, the effect of only allowing the two clamping plates 25 to move toward each other during operation is achieved. When the electrical cabinet is finally taken out after being welded, the ratchet teeth 32 are first flipped upward to disengage the ratchet teeth 32 from the surface of the ratchet wheel 30, so that the bidirectional threaded rod 21 can rotate freely.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
