Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a polishing device for copper rod butt welding. Background Art

[0002] Copper rod butt welding is a process that uses a stable burning arc established between the welding rod and the copper rod to melt the welding rod and the copper rod, thereby obtaining a strong welded joint. In the process of copper rod production, butt welding is usually required. After the butt welding is completed, the welding part of the copper rod needs to be polished and leveled to facilitate the continuous pulling operation of the copper rod to achieve full utilization of the copper rod.

[0003] In the prior art, the copper rod needs to be fixed before grinding and polishing. When the copper rod is fixed, the copper rod is often bent and deformed due to its own gravity and physical properties, which ultimately affects the accuracy of polishing the copper rod surface. In addition, the prior art cannot adjust the position of the grinding plate during the grinding process to adjust the grinding and polishing accuracy. Utility Model Content

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve the technical problems is: a polishing device for copper rod butt welding, comprising a frame, the upper surface of the frame is fixedly connected with a polishing assembly, the inner surface of the polishing assembly is slidably connected with a sliding frame, the inner surface of the sliding frame is slidably connected with a slide rail, the lower surface of the slide rail is fixedly connected to the upper surface of the frame, the upper surface of the frame is fixedly connected with a motor, the output end of the motor is fixedly connected to the outer surface of the polishing assembly, the outer surface of the polishing assembly is fixedly connected with a screw, the outer surface of the left side of the screw is rotatably connected to the inner surface of the frame, when the motor rotates, the sliding frame and the polishing assembly move relative to each other, thereby realizing the polishing process of the copper rod;

[0005] The polishing assembly includes a base, the outer surface of the base is fixedly connected to a fixing ring, the inner surface of the fixing ring is rotatably connected to a hollow sleeve, the inner surface of the hollow sleeve is fixedly connected to a first sliding sleeve, the inner surface of the first sliding sleeve is slidably connected to a polishing plate, and the polishing plate can polish the surface of the copper rod.

[0006] Preferably, the inner surface of the polishing assembly is slidably connected to the outer surface of the sliding frame, the inner surface of the sliding frame is threadedly connected to the outer surface of the screw, the upper surface of the frame is slidably connected to the lower surface of the sliding frame, and the sliding frame can slide along the slide rail and the surface of the frame.

[0007] Preferably, the inner surface of the sliding frame is slidably connected with a clamping claw, the inner surface of the clamping claw is threadedly connected with forward and reverse screw rods, the outer surfaces of the forward and reverse screw rods are rotatably connected to the inner surface of the sliding frame, and a rocker is provided on the outside of the sliding frame, the inner surface of the rocker rod is fixedly connected to the outer surface of the forward and reverse screw rods, and the clamping claw can fix the copper rod.

[0008] Preferably, the inner surface of the base is rotatably connected to a gear, the outer surface of the gear is meshed with a gear ring, the inner surface of the gear ring is fixedly connected to the outer surface of the hollow ring, the lower surface of the base is fixedly connected to the upper surface of the frame, the gear meshes and rotates with the gear ring, and the gear ring drives the hollow ring to rotate along the inner surface of the fixed ring.

[0009] Preferably, the inner surface of the hollow sleeve is fixedly connected to a second sliding sleeve, the inner surface of the second sliding sleeve is slidably connected to a ball sleeve, the outer surface of the ball sleeve is fixedly connected to a compression spring, the bottom end of the compression spring is fixedly connected to the inner surface of the hollow sleeve, and the inner surface of the ball sleeve is rollingly connected to a counterweight ball. Since the mass of the counterweight ball is greater than that of the polishing plate, the centrifugal force of the counterweight ball is greater when the hollow sleeve rotates.

[0010] Preferably, the inner surface of the base is slidably connected to the outer surface of the sliding frame, the outer surface of the gear is fixedly connected to the output end of the motor, and the outer surface of the gear is fixedly connected to the right end of the screw. When the screw rotates, the sliding frame slides along the surface of the slide rail and the frame, and the copper rod moves with the sliding frame.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides auxiliary support by arranging a counterweight ball pair, fixes one end of the copper rod to the clamping claw on the left side of the sliding frame, and the other end passes through the polishing assembly and is fixed to the clamping claw on the right side of the sliding frame. When fixing, the positive and negative screw rods are rotated by the rocker. When the positive and negative screw rods are rotated, the two clamping claws located on the same side move towards each other to clamp the copper rod. The position of the clamping claws can be adjusted by rotating the positive and negative screw rods by the rocker, so as to clamp and fix copper rods of different specifications. When the copper rod passes through the polishing assembly, the surface of the copper rod contacts the surface of the counterweight ball and rolls in the ball sleeve, which can not only provide auxiliary support for the copper rod, but also reduce the resistance of the copper rod when passing through, and solves the problem that the copper rod bends and deforms when the traditional copper rod butt welding polishing device fixes copper rods of different specifications, thereby affecting the effect of subsequent polishing and grinding.

[0013] 2. The utility model grinds the surface of the copper rod by setting a grinding plate. Since the mass of the counterweight ball is greater than the grinding plate, the centrifugal force of the counterweight ball is greater when the hollow sleeve rotates. Under the action of the centrifugal force, the counterweight ball pushes the ball sleeve to shrink into the second sliding sleeve. At this time, the hydraulic oil in the hollow sleeve pushes the grinding plate to slide in the first sliding sleeve. The grinding plate gathers together and contacts the surface of the copper rod to polish the surface of the copper rod. The faster the rotation speed, the greater the centrifugal force on the counterweight ball. Therefore, the degree of contraction of the grinding plate can be controlled, so that copper rods of different specifications can be polished. BRIEF DESCRIPTION OF THE DRAWINGS

The surface is threadedly connected, and the upper surface of the frame 1 is slidably connected with the lower surface of the sliding frame 3. The inner surface of the sliding frame 3 is slidably connected with a clamping claw 7, and the inner surface of the clamping claw 7 is threadedly connected with a positive and negative screw rod 8. The outer surface of the positive and negative screw rod 8 is rotatably connected with the inner surface of the sliding frame 3. A rocker 9 is arranged on the outside of the sliding frame 3, and the inner surface of the rocker 9 is fixedly connected with the outer surface of the positive and negative screw rod 8. One end of the copper rod is fixed to the clamping claw 7 on the left side of the sliding frame 3, and the other end passes through the polishing component 2 and is fixed to the clamping claw 7 on the right side of the sliding frame 3. When fixed, the positive and negative screw rod 8 is rotated by the rocker 9. When the positive and negative screw rod 8 rotates, the two clamping claws 7 located on the same side move in opposite directions to clamp the copper rod. By rotating the positive and negative screw rod 8 by the rocker 9, the position of the clamping claw 7 can be adjusted, thereby clamping and fixing copper rods of different specifications. When the copper rod passes through the polishing component 2, the surface of the copper rod contacts the surface of the counterweight ball 19 and rolls in the ball sleeve 18, which can not only provide auxiliary support for the copper rod, but also reduce the resistance when the copper rod passes through.

[0022] The inner surface of the base 10 is rotatably connected with a gear 14, the outer surface of the gear 14 is meshed with a gear ring 13, the inner surface of the gear ring 13 is fixedly connected to the outer surface of the hollow collar 12, the lower surface of the base 10 is fixedly connected to the upper surface of the frame 1, the inner surface of the hollow collar 12 is fixedly connected with a second sliding sleeve 17, the inner surface of the second sliding sleeve 17 is slidably connected with a ball sleeve 18, the outer surface of the ball sleeve 18 is fixedly connected with a compression spring 20, the bottom end of the compression spring 20 is fixedly connected to the inner surface of the hollow collar 12, the inner surface of the ball sleeve 18 is rollingly connected with a counterweight ball 19, the inner surface of the base 10 is slidably connected to the outer surface of the sliding frame 3, the outer surface of the gear 14 is fixedly connected to the output end of the motor 5, the outer surface of the gear 14 is fixedly connected to the right end of the screw 6, and the motor 5 drives the gear 14 along the base 10 The inner surface of the screw 6 rotates, and the gear 14 rotates to drive the screw 6 to rotate. When the screw 6 rotates, the sliding frame 3 slides along the surface of the slide rail 4 and the frame 1. At this time, the copper rod moves with the sliding frame 3. At the same time, the gear 14 meshes and rotates with the ring gear 13, and the ring gear 13 drives the hollow sleeve 12 to rotate along the inner surface of the fixed ring 11. Because the mass of the counterweight ball 19 is greater than the polishing plate 16, when the hollow sleeve 12 rotates, the centrifugal force of the counterweight ball 19 is greater. Under the action of the centrifugal force, the counterweight ball 19 pushes the ball sleeve 18 to shrink into the second sleeve 17. At this time, the hydraulic oil in the second sleeve 17 enters the hollow sleeve 12, and the hydraulic oil in the hollow sleeve 12 pushes the polishing plate 16 to slide in the first sleeve 15. At this time, the polishing plate 16 is retracted to one piece and contacts with the surface of the copper rod to polish the surface of the copper rod.

[0023] Working principle:

[0024] When in use, one end of the copper rod is fixed to the clamping claw 7 on the left side of the sliding frame 3, and the other end passes through the polishing component 2 and is fixed to the clamping claw 7 on the right side of the sliding frame 3. When fixing, the forward and reverse screw rods 8 are rotated by the rocker 9. When the forward and reverse screw rods 8 are rotated, the two clamping claws 7 on the same side move in opposite directions to clamp the copper rod. The position of the clamping claw 7 can be adjusted by rotating the forward and reverse screw rods 8 by the rocker 9, so as to clamp and fix copper rods of different specifications. When the copper rod passes through the polishing component 2, the surface of the copper rod contacts the surface of the counterweight ball 19 and rolls in the ball sleeve 18, which can not only provide auxiliary support for the copper rod, but also reduce the resistance of the copper rod when passing through.

[0025] The motor 5 drives the gear 14 to rotate along the inner surface of the base 10, and the rotation of the gear 14 drives the screw 6 to rotate. When the screw 6 rotates, the sliding frame 3 slides along the surface of the slide rail 4 and the frame 1. At this time, the copper rod moves with the sliding frame 3. At the same time, the gear 14 meshes with the gear ring 13 to rotate, and the gear ring 13 drives the hollow sleeve ring 12 to rotate along the inner surface of the fixed ring 11. Because the mass of the counterweight ball 19 is greater than the polishing plate 16, when the hollow sleeve ring 12 rotates, the centrifugal force of the counterweight ball 19 is greater. Under the action of the centrifugal force, the counterweight ball 19 pushes the ball sleeve 18 to the second The sliding sleeve 17 contracts, and the hydraulic oil in the second sliding sleeve 17 enters the hollow collar 12. The hydraulic oil in the hollow collar 12 pushes the grinding plate 16 to slide in the first sliding sleeve 15. At this time, the grinding plate 16 is retracted to one piece and contacts the surface of the copper rod to polish the surface of the copper rod. The faster the rotation speed, the greater the centrifugal force exerted on the counterweight ball 19, thereby controlling the retraction degree of the grinding plate 16, thereby polishing copper rods of different specifications. When the device is not working, the compression spring 20 drives the ball sleeve 18 to reset, and the grinding plate 16 is also reset due to the influence of negative pressure.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
