Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt welding, in particular to a hot-melt welding device for a cable joint. Background Art

[0002] Hot melt is generally used for hot melt connection. The principle of hot melt connection is to place the mating surfaces of two pipes or wires close to a heating tool to heat their flat end surfaces until they melt. After removing the heating tool, the two molten end surfaces are pressed together and maintained under pressure until the joint cools down, so that the two sections of the workpiece are connected as a whole.

[0003] For example, a cable joint hot-melt welding device disclosed in patent number CN217740957U includes a clamp that moves on the upper surface of two mounting frames for inserting cables, the bottom surfaces of both ends of the mounting frames are fixedly connected with support plates, the other end of the two-way threaded rod passes through the adjustment plate and is connected with a bolt, the outer surface of the bolt is threadedly connected with a fixing nut, and there are two clamps in total, which are both threadedly connected to the outer surface of the two-way threaded rod through a slider, and are arranged oppositely. By providing a support plate that can be pulled out at both ends of the mounting frame, and an adjustment plate that is supported and connected by a hydraulic rod above the support plate, the cable can have a support that can be pulled out and used at any time when inserted, and at the same time, the adjustment plate connected by the hydraulic rod can have a stable clamping effect on the outer surface of the cable through the clamp on the surface of the adjustment plate, so that the cable has a stable placement state when placed, and the device is easy to operate.

[0004] In the prior art, the cable is placed on an adjusting plate, clamped by a clamping plate, and then inserted into a clamping sleeve and fixed by the clamping sleeve.

Long-term tilting causes the cable to deform, affecting subsequent use. The two groups of cables that need to be welded are placed on two groups of workbenches 3 respectively, and then the cables are clamped left and right by the clamping plates 4 in the clamping assembly 23 on the workbench 3 to prevent the cables from shifting left and right during welding, affecting the welding quality. The welding ends of the cables are then fixed by the pressing plates 19 in the fixing assembly 22 to prevent the cables from tilting during welding. During the welding process, the two groups of cables need to maintain a uniform height so that the welding ends of the two groups of cables can fit together. When the height of the group workbench 3 is adjusted, the staff can rotate the driving shaft 14. When the driving shaft 14 rotates, the driving gear 13 can be driven to rotate. When the driving gear 13 rotates, the transmission gear 12 can be driven to rotate through the teeth. The driving gear 13 and the transmission gear 12 are both bevel gears. When the transmission gear 12 rotates, the lifting screw 9 can be driven to rotate. While rotating, the lifting ring 11 connected to the ball nut will move up and down.

[0026] In one embodiment of the utility model, a clamping screw 6 is rotatably connected in the clamping groove 7 in the clamping assembly 23; a moving block 25 is threadedly connected to the clamping screw 6; two groups of moving blocks 25 are provided; a clamping plate 4 is fixedly connected to the end of the moving block 25; a clamping pad 5 is fixedly connected to the side wall of the clamping plate 4. During operation, the clamping screw 6 can drive the two groups of moving blocks 25 to produce relative movement when it rotates, that is, move to both sides of the workbench 3 or move to the middle of the workbench 3 at the same time. After placing the cable on the workbench 3, the clamping screw 6 is driven to rotate, driving the moving block 25 to move to the middle of the workbench 3 at the same time, and clamping the cable. When clamping, the clamping pad 5 can prevent the cable from being damaged by the clamping plate 4, and prevent the cable from shaking and deflecting during welding.

[0028] In one embodiment of the utility model, the side walls on both sides of the clamping groove 7 are fixedly connected to the limiting grooves 8; the two ends of the moving block 25 are clamped in the limiting grooves 8. When working, the limiting grooves 8 are set on both sides of the clamping screw 6. When the moving block 25 moves, it may be offset, which may cause the moving block 25 to be stuck. By setting the limiting grooves 8, the moving block 25 can be kept in a parallel state at all times to avoid offset during movement.

[0029] In one embodiment of the utility model, the clamping pad 5 and the bottom pad 21 are both made of rubber material; the clamping assembly 23 and the fixing assembly 22 are each provided with two groups. When working, the rubber material is relatively soft and can play a role in protecting the cable.

During operation, the base 1 may shake, the support leg 15 can alleviate the shaking, and the rubber pad 16 can prevent slipping during shaking.

[0033] Working principle: In order to overcome the problem in the prior art that the clamping sleeve cannot rise with the adjustment plate during the lifting process, the cable in the clamping sleeve cannot rise either, causing the rear end of the cable to be tilted. Long-term tilting causes the cable to be deformed, affecting subsequent use. The two groups of cables to be welded are placed on two groups of workbenches 3 respectively, and then the cables are clamped left and right by the clamping plates 4 in the clamping assembly 23 on the workbench 3 to prevent the cables from shifting left and right during welding, affecting the welding quality. Then the welding ends of the cables are fixed by the pressing plates 19 in the fixing assembly 22 to prevent the cables from tilting during welding. During the welding process, the two groups of cables need to maintain a uniform height so that the welding ends of the two groups of cables can be aligned. When adjusting the height of the two groups of workbenches 3, the staff can rotate the driving shaft 14. When the driving shaft 14 rotates, it can drive the driving gear 13 to rotate. When the driving gear 13 rotates, it can drive the transmission gear 12 to rotate through the teeth. The driving gear 13 and the transmission gear 12 are both bevel gears. When the transmission gear 12 rotates, it can drive the lifting screw 9 to rotate. While rotating, the lifting ring 11 connected by the ball nut will move up and down. The ball nut is composed of a ball nut, a steel ball, a circulation mechanism and accessories. When moving up and down, the workbench 3 can be driven to move up and down through the connecting column 10, and the two groups of workbenches 3 can be lifted and lowered at different heights to adapt to the welding of cable end faces.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
