Technical Field

[0001] The utility model relates to the technical field of welding, and more specifically to a part welding anti-splash clamp device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken during welding. The possible injuries to the human body caused by welding include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

The clamping plate 4 is adjusted by moving the moving block 26 to clamp different parts, thereby improving the practicability of the device.

[0033] The improvement of this embodiment is that: the first servo motor 14 drives the rotating shaft 12 to rotate, and drives the first transmission gear 13 to rotate, so that the first transmission gear 13 drives the two first long racks 11 located on the outside thereof to move, and drives the T-block 10 to slide in the T-slot 9, so that the protective covers 2 located on both sides of the top of the workbench 1 are close to each other, and the welding area is isolated, thereby effectively shielding the sparks and splashing welding slag generated during the welding work, so as to avoid these splashes from accidentally injuring the surrounding workers and damaging the health of the workers, and the welding situation inside the protective cover 2 is always known through the observation window, and corresponding adjustments are made, and the rotating shaft 12 is driven to rotate by the first servo motor 14, so that the first transmission gear 13 and the second transmission gear 15 rotate at the same time, and the second transmission gear 15 rotates to drive a pair of second long racks 18 to move, so that the second long racks 18 drive the slider 17 at the bottom of the moving plate 3 to slide in the first slide groove 16, and the second long rack 18 on one of the moving plates 3 slides in the second slide groove 19 on the other moving plate 3, so that the protective covers 2 are close to each other and the moving plates 3 are also close to each other at the same time, because the protective covers 2 The moving distance is much larger than that of the moving plate 3, so through the setting of the movable teeth 28 of the buffer assembly, when the movable teeth 28 on the second long rack 18 mesh with the second transmission gear 15, because the connecting plates 22 on the top and bottom ends of the movable teeth 28 are sleeved on the outer side of the sliding column 21 between a pair of short columns, and a return spring 27 is also arranged therebetween, the movable teeth 28 will move toward the center of the workbench 1 as the second transmission gear 15 rotates, but will immediately rebound to the original position under the restriction of the return spring 27, so that the pair of moving plates 3 will no longer approach each other, thereby avoiding damage to parts. Bad, until the protective covers 2 on both sides are closed, welding begins, thereby effectively improving the linkage between the devices, while reducing the corresponding operation steps and improving work efficiency, and the second servo motor 25 in the adjustment component drives the two-way reciprocating screw 24 in the groove 23 on one side of the moving plate 3 to rotate, so that a pair of moving blocks 26 on the outside of the two-way reciprocating screw 24 are close to each other and drive a pair of clamping plates 4 to approach each other, clamping and fixing the parts, and adjusting the clamping plate 4 to clamp different parts by moving the moving block 26 to move the distance, thereby improving the practicability of the device.

[0034] In summary, the working principle of this solution is as follows:

[0035] Before welding, the two parts to be welded are placed in a pair of clamping plates 4 for clamping respectively. The second servo motor 25 in the adjustment assembly drives the bidirectional reciprocating screw 24 in the groove 23 on one side of the moving plate 3 to rotate, so that a pair of moving blocks 26 outside the bidirectional reciprocating screw 24 approach each other and drive a pair of clamping plates 4 to approach each other, and the parts are clamped and fixed. The clamping plates 4 are adjusted by moving the moving blocks 26 to clamp different parts, thereby improving the practicality of the device. After the parts are fixed, the rotating shaft 12 is driven to rotate by the first servo motor 14, and the first transmission gear is driven The wheel 13 rotates, so that the first transmission gear 13 drives the two first long racks 11 located outside thereof to move, and drives the T-block 10 to slide in the T-slot 9, so that the protective covers 2 located on both sides of the top of the workbench 1 are close to each other, and the welding area is isolated, thereby effectively shielding the sparks and splashing welding slag generated during the welding work, thereby preventing these splashes from accidentally injuring the surrounding workers and damaging the health of the workers, and the welding situation inside the protective cover 2 can be understood at all times through the observation window, and corresponding adjustments can be made. At the same time, the first servo motor 14 drives the rotating shaft 12 to rotate, which will make the first transmission gear The wheel 13 and the second transmission gear 15 rotate at the same time, and the second transmission gear 15 rotates to drive a pair of second long racks 18 to move, so that the second long racks 18 drive the slider 17 at the bottom of the moving plate 3 to slide in the first slide groove 16, and the second long rack 18 on one moving plate 3 slides in the second slide groove 19 on the other moving plate 3, so that the protective covers 2 are brought closer to each other and the moving plates 3 are also brought closer to each other at the same time. Because the moving distance of the protective cover 2 is much greater than that of the moving plate 3, the movable teeth 28 of the buffer assembly are set, when the movable teeth 28 on the second long rack 18 mesh with the second transmission gear 15 When closing, because the connecting plates 22 on the top and bottom ends of the movable teeth 28 are sleeved on the outer side of the sliding column 21 located between a pair of short plates 20, and a return spring 27 is also arranged therebetween, the movable teeth 28 will move toward the center of the workbench 1 as the second transmission gear 15 rotates, but will immediately rebound to the original position under the restriction of the return spring 27, so that the pair of movable plates 3 will no longer be close to each other, avoiding damage to parts, and welding will not begin until the protective covers 2 on both sides are closed, thereby effectively improving the linkage between the devices, while reducing the corresponding operating steps and improving work efficiency.
