Abstract
Description
Technical Field
[0001] This invention belongs to the field of high-voltage cable welding, and specifically relates to a high-voltage cable welding and polishing device. Background Technology
[0002] Cables generally refer to wires that transmit power or electrical signals. After the cable is laid, in order to make it a continuous line, the sections of the line must be connected as a whole. A fusion splicer is used to connect the main insulation layers of the cable joints together, so that the cable line becomes a whole, which ensures that the cable has good sealing performance and improves the service life of the cable.
[0003] Currently, after the cable is heat-fused, its insulation layer needs to be chamfered. The insulation treatment of the intermediate joint mainly relies on manual grinding with a handheld grinder. This requires high operational skills, has low standardization, and suffers from problems such as high labor costs, long grinding time, and uneven grinding. Summary of the Invention
[0004] The present invention aims to provide a high-voltage cable welding and polishing device to solve the problems of low standardization and time-consuming and labor-intensive manual polishing in the prior art.
[0005] This solution provides a high-voltage cable splicing and polishing device, comprising a polishing mechanism and two circular baffles. Both baffles are perpendicular to the ground and parallel to each other. Each baffle has a wire inlet groove on one side, extending from the side wall to the center of the baffle, and the two wire inlet grooves are parallel to the ground. A movable part is slidably connected between the two baffles. Slide rails are slidably connected to the movable part at the contact points with the two baffles. The two slide rails are arc-shaped and fixedly connected to the side walls of the two baffles. A stepper motor is installed inside the movable part to drive it to slide along the slide rails. The polishing mechanism is located on the side of the movable part closer to the center of the baffle.
[0006] The working principle and beneficial effects of this solution are as follows: During use, the spliced cable with the portion requiring grinding is placed along the cable entry groove into the center of the two baffles. Then, the grinding mechanism is activated to grind the cable. During grinding, the stepper motor within the moving part can be activated, causing the moving part and grinding mechanism to slide along the slide rail and rotate around the sidewalls of the baffles, thus uniformly grinding the cable around its perimeter. After the cable splicing is complete, the cable joint can be placed between the two baffles for grinding the insulation layer. The entire grinding mechanism can rotate and grind around the cable simultaneously, shortening grinding time and improving grinding efficiency. Furthermore, machine grinding effectively controls the standardization of the cable joint, preventing uneven grinding.
[0007] Furthermore, the bottom of the moving part is provided with a track, which extends from one baffle to another. The grinding mechanism is slidably connected to the track, and a linear motor is provided inside the grinding mechanism to drive its translation. The grinding mechanism can move left and right along the track between the two baffles, increasing the movement space of the grinding mechanism and accelerating the grinding speed of the cable insulation layer.
[0008] Furthermore, the polishing mechanism includes a fixed part and a telescopic part. The fixed part and the telescopic part are slidably connected to the track at the positions where they contact the moving part. The telescopic part can extend and retract vertically. A rotating component is fixedly connected to the end of the fixed part and the telescopic part away from the moving part. A polishing wheel is rotatably connected to the end of each of the two rotating components away from the moving part. A motor that drives the rotation of one of the polishing wheels is fixedly connected inside. Sandpaper is wound between the two polishing wheels.
[0009] In use, start the motor to drive the grinding wheel to rotate, which in turn causes the sandpaper between the two grinding wheels to move around the two grinding wheels to grind the cable insulation layer. At the same time, when it is necessary to limit the grinding angle, the rotating component can be activated to drive the two grinding wheels to deflect to the required angle. When the grinding degree is different, the telescopic part can be opened to drive the lower grinding wheel to descend and approach the cable to grind the deep part of the cable.
[0010] Furthermore, the rotating assembly includes a rotating bracket and a rotating column. Each end of the grinding wheel is rotatably connected to a bracket. A connecting rod is provided at the end of each bracket furthest from the grinding wheel. Both ends of the connecting rod are fixedly connected to the brackets at both ends of the grinding wheel. The connecting rod passes through the middle of the rotating column and is perpendicular to the rotating column. The connecting rod is fixedly connected to the rotating column, and the rotating column is rotatably connected to the rotating bracket. A motor that drives the rotating column to rotate is located inside the rotating bracket. The end of the rotating bracket furthest from the rotating column is fixedly connected to a fixed part or a telescopic part. When it is necessary to adjust the grinding angle, the motor can be turned on to drive the rotating column to rotate, thereby causing the connecting rod and bracket to rotate together, thus deflecting the grinding angle of the grinding wheel without affecting its grinding effect.
[0011] Furthermore, each of the two baffles has a fixed cable retaining groove on the side near the grinding mechanism. The cable retaining groove is located below the cable inlet groove, and the top of the cable retaining groove is flush with the bottom of the cable inlet groove. The cable retaining groove plays a supporting role when the grinding mechanism grinds the cable, preventing it from swaying downwards under the impact of the grinding mechanism, which would affect the grinding efficiency.
[0012] Furthermore, a base is fixedly connected to the lower part of the baffle. The base facilitates the placement of the circular baffle. Attached Figure Description

[0020] The basic implementation examples are as follows: Figures 1-5 As shown: A high-voltage cable splicing and polishing device includes a moving part 4, a polishing mechanism 5, and two parallel baffles 6, with the two baffles 6 perpendicular to the ground. A base 1 is fixedly connected to the bottom of each of the two baffles 6. A wire inlet groove 3 is opened on the front side of each of the two baffles 6, extending from the side wall of the baffle 6 to the center of the baffle 6. A wire fixing groove 7 is provided below the wire inlet groove 3, and the wire fixing groove 7 is fixedly connected to the side of the two baffles 6 near the polishing mechanism 5. The top of the wire fixing groove 7 is flush with the bottom of the wire inlet groove 3. A moving part 4 is provided between the two baffles 6. An arc-shaped slide rail 2 is provided near the outer periphery of the two baffles 6, and the slide rail 2 is fixedly connected to the side wall of the baffle 6. The two ends of the moving part 4 are slidably connected to the two slide rails 2 respectively. A stepper motor is provided inside the moving part 4 to drive its movement. The polishing mechanism 5 is located at the bottom of the moving part 4 and points towards the center of the two baffles 6.
[0021] The grinding mechanism 5 includes a fixed part 55, a telescopic part 54, sandpaper 58, and two grinding wheels 51. The bottom of the moving part 4 is fixedly connected to two tracks 8, which extend from one baffle 6 to the other. The fixed part 55 and the telescopic part 54 are slidably connected to the two tracks 8 respectively. The fixed part 55 and the telescopic part 54 are each equipped with a linear motor to drive their translation. The sandpaper 58 is wound between the two grinding wheels 51. Both ends of the two grinding wheels 51 are rotatably connected to brackets 52. The brackets 52 are equipped with motors to drive the grinding wheels 51 to rotate. A connecting rod 57 is fixedly connected between the brackets 52 at both ends of the same grinding wheel. A rotating column 56 is fixedly connected to the middle of the connecting rod 57. The rotating column 56 is perpendicular to the connecting rod 57. The two ends of the rotating column 56 are rotatably connected to rotating brackets 53. The rotating brackets 53 are equipped with motors to drive the rotating column 56 to rotate. The two rotating brackets 53 are fixedly connected to the bottom of the fixed part 55 and the telescopic part 54.
[0022] The specific implementation process is as follows: During use, the welded joint of the welded cable is passed through the inlet groove 3 and enters the center of the device. Then, the motor of the grinding wheel 51 is turned on to grind the insulation layer of the cable. During grinding, in order to grind the cable around, the stepper motor in the moving part 4 can be turned on to slowly drive the moving part 4 to slide along the slide rail 2, thereby driving the grinding mechanism 5 below to rotate around the cable, so that the grinding mechanism 5 grinds the cable insulation layer in all directions. During grinding, the stepper motors of the fixed part 55 and the telescopic part 54 can also be turned on to move them horizontally on the track 8, thereby moving the grinding mechanism 5 horizontally to increase the grinding range. The telescopic part 54 can also be activated to extend it downward, driving the grinding wheel 51 closer to the cable, increasing the depth of the grinding mechanism 5. When a grinding angle is required, the motor of the rotating column 56 can be turned on to drive the connecting rod 57 to deflect to the required angle, thereby driving the grinding wheel 51 to chamfer the cable insulation layer.
