Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a clamping device for welding. Background Art

[0002] After more than a century of development, welding has penetrated into various fields of manufacturing. Almost all products rely on welding technology to varying degrees in production. When welding workpieces, welding clamps are often used to fix them.

[0003] In order to prevent the clamping plate from damaging the surface of the workpiece, some clamping devices on the market often have buffer pads and other devices on the surface of the clamping plate to play a buffering role during clamping. However, after a long period of use, the buffer pad loses its elasticity and protective ability and needs to be replaced, which is inconvenient. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a clamping device for welding. When the buffer pad is disassembled and replaced, the baffle is pushed to move and no longer blocks the buffer pad. The baffle squeezes the spring when it moves, and then the buffer pad is pulled out upward for disassembly. The new buffer pad is slid into the second slide groove for fixation, and then the baffle is released to drive it to return to its original position under the action of the spring rebound to block the buffer pad, thereby preventing the buffer pad from falling off during use, thereby completing the installation of the buffer pad for easy use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a welding clamping device comprises a fixed plate, the top end of the fixed plate is fixedly connected to a linear rail, the surface of the linear rail is slidably connected to two first sliding blocks, the top end of the first sliding block is fixedly connected to a sliding plate, the bottom end of the sliding plate is movably connected to a connecting plate, the two connecting plates are movably connected to a movable plate at one end away from the sliding plate, the opposite surfaces of the movable plate and the fixed plate are fixedly connected to a cylinder, the one end of the sliding plate away from the first sliding block is fixedly connected to a clamping plate, the opposite surfaces of the two clamping plates are respectively provided with a first sliding groove, the interior of the first sliding groove is slidably connected to a buffer pad, the top end of the sliding plate is provided with a second sliding groove, the interior of the second sliding groove is fixedly connected to a spring, one end of the spring is fixedly connected to a baffle, and the baffle is slidably connected to the interior of the second sliding groove.

[0006] Furthermore, a plurality of anti-skid grooves are provided on the surface of the buffer pad, and the fixing plate movably penetrates the skateboard.

[0007] Furthermore, a reinforcing rib is provided at one end of the clamping plate away from the first sliding groove, and the bottom end of the reinforcing rib is fixedly connected to the top end of the sliding plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. When removing and replacing the buffer pad, push the baffle to move so as not to block the buffer pad. When the baffle moves, squeeze the spring, then pull the buffer pad upward for removal, slide the new buffer pad into the second slide groove for fixation, then release the baffle to drive it to return to its original position under the action of the spring rebound to block the buffer pad to prevent the buffer pad from falling off during use, and then complete the installation of the buffer pad for easy use.

[0010] 2. The cylinder drives the moving plate to move, the moving plate drives the connecting plate to move, the connecting plate drives the sliding plate to move, the movement of the sliding plate drives the first slider to slide on the surface of the linear rail, thereby driving the two clamping plates to move in opposite directions to clamp and fix the welding workpiece.

[0019] One end of the clamping plate 8 away from the first sliding groove 9 is provided with a reinforcing rib, and the bottom end of the reinforcing rib is fixedly connected to the top end of the slide plate 4 .

[0020] Working principle: when in use, the fixed plate 1 of the device is fixed, and the cylinder 7 is started when clamping the welding workpiece, and the cylinder 7 drives the movable plate 6 to move, and the movable plate 6 drives the connecting plate 5 to move, and the connecting plate 5 drives the slide plate 4 to move, and the movement of the slide plate 4 drives the first slide block 3 to slide on the surface of the linear rail 2, thereby driving the two clamping plates 8 to move in opposite directions to clamp and fix the welding workpiece. Through the setting of the buffer pad 10, it can play a buffering role when the welding workpiece is clamped to prevent damage to the surface of the workpiece. The arrangement of the grooves plays an anti-slip role when clamping the workpiece. When the buffer pad 10 is disassembled and replaced, the baffle 13 is pushed to move and no longer blocks the buffer pad 10. The baffle 13 squeezes the spring 12 when moving, and then the buffer pad 10 is pulled out upward for disassembly, and the new buffer pad 10 is slid into the second slide groove 11 for fixation, and then the baffle 13 is released to drive the spring 12 to return to its original position under the action of the rebound to block the buffer pad 10, thereby preventing the buffer pad 10 from falling off during use, and then completing the installation of the buffer pad 10 for easy use.
