Description

Technical Field

[0001] This application relates to the technical field of copper wire surface grinding, and particularly relates to a copper wire surface grinding and processing device. Background Art

[0002] During the continuous production process of copper wire, the copper wire may break or a new copper wire spool needs to be replaced. To maintain the continuity of production, the two ends of the broken copper wire need to be welded together, or the new copper wire and the old copper wire need to be connected. And in multiple drawing or stranding processes, after the copper wire undergoes multiple stretches and deformations, breaks may occur at the joints. Welding can be used to repair the joints to ensure the continuous operation of the production line.

[0003] After welding the copper wire, it is necessary to grind the welded part of the copper wire. Thereby, the flatness of the surface of the processed material is ensured. When grinding the surface of the copper wire, the operator needs to hold a grinding tool to grind the welded part of the copper wire. And during the grinding process, it is necessary to continuously adjust the grinding angle and the contact distance between the grinding tool and the copper wire back and forth.

[0004] Referring to the Chinese patent document with the publication number CN211867385U and the name of a surface grinding tool for processing copper alloy welding materials, this device drives the first screw rod to rotate through the first motor, causing the first movable block to move, driving the connecting cover, the support rod, and the grinding motor to move, thus eliminating the need for manual back-and-forth grinding, which is more time-saving and labor-saving. When the second motor drives the second movable block to move, the movable block drives the connecting rod to pull or push the grinding motor, causing the support rod to swing and adjusting the grinding angle of the grinding motor, making the grinding of the grinding motor more suitable for processed materials with side grinding.

[0005] For the above technical solution, when grinding the welded part of the copper wire, the operator needs to hold a grinding tool to grind the welded part of the copper wire. When grinding the copper wire, it is necessary to pull both ends of the welded part of the copper wire to keep the copper wire flat for easy observation of the grinding degree. At the same time, during grinding, the operator needs to pay attention to the grinding depth. When the operation is improper, it is easy to cause excessive grinding of the welded part of the copper wire, affecting the quality, and multiple people need to cooperate during the process of straightening the copper wire, affecting the work efficiency. Summary of the Invention

[0006] In view of this, this application provides a copper wire surface grinding and processing device, aiming to solve the problem that it is easy to cause inconsistent grinding depths when grinding the welded part of the copper wire.

[0007] A copper wire surface grinding device provided by the present application adopts the following technical solution, including a support frame and a grinding mechanism arranged on the support frame for grinding the surface of the copper wire; a connecting block is fixedly connected to the support frame, a sliding block is slidably connected to the connecting block, a rotating block is rotatably connected to the sliding block, a placement groove is formed on the rotating block, a control rotating wheel is slidably connected to the rotating block, a connecting spring is fixedly connected to the control rotating wheel, and one end of the connecting spring away from the control rotating wheel is fixedly connected to a clamping block, and the clamping block is arranged inside the rotating block.

[0008] The surface of the copper wire is ground by the grinding mechanism on the support frame. First, place the copper wire in the placement groove of the rotating block and fix it; then, operate the control rotating wheel, pull the clamping block to close through the connecting spring, and clamp the copper wire; then, start the grinding mechanism, and make the rotating block drive the copper wire to rotate for grinding. At this time, the grinding effect can be controlled by finely adjusting the clamping force of the control rotating wheel and the rotation of the rotating block; finally, stop grinding and operate the control rotating wheel in the reverse direction to open the clamping block and release the ground copper wire.

[0009] Clamping the copper wire and driving the copper wire to rotate has many benefits for the welded copper wire. First, placing the copper wire in the placement groove of the rotating block and fixing it can ensure that the copper wire remains stable during grinding, avoiding uneven grinding or damage to the copper wire caused by the shaking of the copper wire.

At this time, by finely adjusting the clamping force of the control rotating wheel and the rotation of the rotating block, the grinding force and effect can be controlled, so that the surface of the copper wire reaches the expected roughness and improves the welding quality. Finally, stopping grinding and operating the control rotating wheel in the reverse direction to open the clamping block and release the ground copper wire can avoid deformation or damage to the copper wire caused by long-term clamping.

[0011] When the control rotating wheel moves towards the rotating block, it pushes the rack to drive the meshing rack to move towards the outer wall of the copper wire, thereby firmly clamping the copper wire. The benefits of this design are significant: First, by controlling the rotation angle of the control rotating wheel, the clamping force can be precisely controlled to avoid damaging the copper wire or causing slippage, ensuring the grinding quality; Second, the gear-rack mechanism has strong rigidity and high stability, preventing the copper wire from loosening or shifting during high-speed rotation and grinding; Third, the transmission efficiency of this mechanism is high, which can quickly respond to operations and improve the grinding efficiency; Finally, by evenly clamping the copper wire, excessive local stress is avoided, effectively protecting the copper wire. In summary, through precisely controlling the clamping force, enhancing stability, improving efficiency, and protecting the copper wire, this gear-rack clamping mechanism significantly improves the quality and efficiency of copper wire grinding, ensuring that the surface of the ground copper wire is uniform and smooth, meeting the requirements of subsequent processes.

Then, starting the grinding mechanism and driving the copper wire to rotate by the rotating block for grinding can make the surface of the copper wire evenly contact with the grinding mechanism, avoiding damage to the copper wire due to excessive local grinding. At this time, by finely adjusting the clamping force of the control wheel and the rotation of the rotating block, the grinding force and effect can be controlled, so that the surface of the copper wire reaches the expected roughness and the welding quality is improved.

Detailed Description of the Embodiment

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be described clearly and completely below in conjunction with the Figures 1-7 of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0028] Such as Figure 1As shown in the figure, this embodiment provides a copper wire surface grinding device, which includes a support frame 1, a grinding mechanism 2, a rotating clamping mechanism, a linkage stretching mechanism, a limiting mechanism, and a buffering mechanism. The support frame 1 is placed on a horizontal plane. The grinding mechanism 2 is used to grind the welding joint of the copper wire. The rotating clamping mechanism is used to clamp the copper wire and drive the copper wire to rotate. The linkage stretching mechanism is used to link the rotating clamping mechanism and drive the copper wire to be straightened during the rotation of the rotating clamping mechanism. The limiting mechanism is used to limit the rotation angle of the rotating clamping mechanism. The buffering mechanism is used to reduce the occurrence of excessive grinding caused by inconsistent diameters at the welding joints.

[0029] As Figure 1 and Figure 2 shown in the figure, the grinding mechanism 2 includes a rotating motor 21 and a grinding turntable 22. The rotating motor 21 is fixedly connected to the support frame 1, and the grinding turntable 22 is fixedly connected to the output shaft of the rotating motor 21. The grinding turntable 22 is used to grind the welding joint of the copper wire.

[0030] When it is necessary to grind the welding joint of the copper wire, start the rotating motor 21, so that the output shaft of the rotating motor 21 rotates to drive the grinding turntable 22 to rotate, and the grinding turntable 22 grinds the welding joint of the copper wire.

[0031] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown in the figure, the rotating clamping mechanism includes a connecting block 3, a sliding block 31, a rotating block 32, a placement groove 33, a control wheel 34, a connecting spring 35, and a clamping block 36. The connecting block 3 is fixedly connected to the support frame 1, and there are two connecting blocks 3. The two connecting blocks 3 are arranged on both sides of the grinding turntable 22. The sliding block 31 is slidably connected to the connecting block 3. The rotating block 32 is rotatably connected to the clamping block 36. The placement groove 33 is opened on the rotating block 32. The control wheel 34 is slidably connected to the rotating block 32. The connecting spring 35 is fixedly connected to the control wheel 34 and is arranged on the side of the control wheel 34 facing the rotating block 32. The clamping block 36 is fixedly connected to the side of the connecting spring 35 away from the control wheel 34 and is arranged inside the rotating block 32.

[0032] After welding the copper wire, move the copper wire to the placement groove 33, and drive the welded part of the copper wire to the middle position between the two connecting blocks 3. The clamping block 36 clamps the copper wire, and after clamping, start the rotating motor 21 to make the output shaft of the rotating motor 21 rotate. The rotation of the output shaft of the rotating motor 21 drives the grinding turntable 22 to rotate, so that the grinding turntable 22 grinds the welded part close to the grinding turntable 22. When grinding to a certain extent, drive the control runner 34 to rotate, so that the axial side walls of the welded part of the copper wire all rotate to the end close to the grinding turntable 22, and under the grinding of the grinding turntable 22, the welded part is ground.

[0033] As Figure 3 , Figure 5 and Figure 6 As shown in, the linkage stretching mechanism includes a pushing rack 4, a meshing rack 41, a rotating gear 42, a rotating roller 43, a driven gear 44 and a cleaning brush 63. The pushing rack 4 is fixedly connected to the inner side wall of the rotating block 32. The meshing rack 41 is fixedly connected to the sliding block 31, and the meshing rack 41 can mesh with the pushing rack 4. The rotating gear 42 is fixedly connected to the rotating block 32. The rotating roller 43 is rotatably connected to the middle position between two adjacent connecting blocks 3. The driven gear 44 is fixedly connected to the rotating roller 43. The cleaning brush 63 is fixedly connected to the rotating roller 43.

[0034] After placing the copper wire, push the control runner 34 to move towards the welded part of the copper wire. Due to the fixation of the pushing rack 4, when the meshing rack 41 located at the clamping block 36 moves towards the pushing rack 4, it is blocked by the pushing rack 4, so that the meshing rack 41 moves away from the welded part relative to the clamping block 36. And due to the inclination of the teeth on the rack, the meshing rack 41 gets closer to the copper wire. When the control runner 34 rotates, it drives the rotating gear 42 to rotate. And because the rotating gear 42 meshes with the driven gear 44, the rotating roller 43 rotates, so that the connecting block 3 on the side away from this connecting block 3 rotates synchronously with this connecting block 3, synchronously driving the copper wire to rotate. And when the grinding turntable 22 grinds the copper wire, the cleaning brush 63 located on the rotating roller 43 cleans the grinding turntable 22.

[0035] As Figure 3 and Figure 4 As shown in, the limiting mechanism includes an abutting block 5, an abutting groove 51, a control slider 52, a blocking block 53 and a limiting block 54. The abutting block 5 is fixedly connected to the control runner 34. The abutting groove 51 is opened on the sliding block 31, and the abutting block 5 can extend into the abutting groove 51 to fix the control runner 34. The control slider 52 is slidably connected to the sliding block 31. The blocking block 53 is fixedly connected to the control slider 52. The limiting block is fixedly connected to the rotating block 32. And when the limiting block 54 rotates 180 degrees, it will abut against the blocking block 53.

[0036] When rotating the control rotating wheel 34, it is necessary to pull the control rotating wheel 34 to move the abutting block 5 on the control rotating wheel 34 out of the abutting groove 51. When it is necessary to fix the control rotating wheel 34, push the control rotating wheel 34 to move it towards the position of the sliding block 31, and move the abutting block 5 into the abutting groove 51 to fix the control rotating wheel 34. When rotating the control rotating wheel 34, the limiting block 54 on the control rotating wheel 34 rotates with the control rotating wheel 34, and after rotating 180 degrees, it abuts against the blocking block 53 and pushes the control slider 52 to move downward. When reversing the control rotating wheel 34, the limiting block 54 reverses, drives the control rotating wheel 34 to rotate, and after the limiting block 54 reversely rotates 180 degrees, it abuts against the blocking block 53 and pushes the control slider 52 to move upward.

[0037] Among them, as Figure 3 shown, an auxiliary connecting rod 6 is fixedly connected to the connecting block 3, an auxiliary connecting block 61 is fixedly connected to the auxiliary connecting rod 6, and an auxiliary rotating roller 62 is fixedly connected to the auxiliary connecting block 61. The auxiliary rotating roller 62 is used for auxiliary support and auxiliary rotation of the copper wire.

[0038] Place the two copper wires to be welded together on the auxiliary rotating rollers 62 at both ends respectively. When it is necessary to drive the copper wire to rotate, the auxiliary rotating roller 62 can provide a certain supporting force to the copper wire and will not affect the rotation of the copper wire.

[0039] As Figure 7 shown, the buffer mechanism includes a buffer rod 7, a buffer oil cylinder 71, a buffer pad 72, a tension spring 73 and an adjusting rotating wheel 74. The buffer rod 7 is slidably connected to the sliding block 31. The buffer oil cylinder 71 is arranged on the connecting block 3. The buffer pad 72 is fixedly connected to the buffer rod 7. The tension spring 73 is fixedly connected to the sliding block 31, and the end of the tension spring 73 away from the sliding block 31 is fixedly connected to the connecting block 3. The adjusting rotating wheel 74 is rotatably connected to the sliding block 31. The adjusting rotating wheel 74 and the buffer rod 7 are connected by a threaded connection. The adjusting rotating wheel 74 is used to adjust the distance between the sliding block 31 and the buffer rod 7.

[0040] When grinding the surface of the copper wire, due to the different diameters at the welding joints, when grinding the surface of the copper wire, the distance between the welding joint of the copper wire and the grinding turntable 22 can be adjusted by rotating the adjustment wheel 74. At the same time, due to the different diameters, after grinding the area with a larger diameter, when rotating the copper wire, due to the lack of support at the welding joint, the force of the tension spring 73 is greater than the supporting force at the welding joint, causing the tension spring 73 to drive the sliding block 31 to move towards the side close to the grinding turntable 22. When the sliding block 31 moves, the buffer pad 72 undergoes a certain buffer in the buffer oil cylinder 71 to reduce the situation of excessive grinding at the welding joint of the copper wire caused by direct movement. When this application is in use, after welding the copper wire, move the copper wire into the placement groove 33 and drive the welding joint of the copper wire to the middle position between the two connecting blocks 3. The clamping block 36 clamps the copper wire, and after clamping, start the rotating motor 21 to make the output shaft of the rotating motor 21 rotate. The rotation of the output shaft of the rotating motor 21 drives the grinding turntable 22 to rotate, so that the grinding turntable 22 grinds the welding joint close to the grinding turntable 22. When grinding to a certain extent, by driving the control wheel 34 to rotate, the axial side walls of the copper wire welding joint are all rotated to the end close to the grinding turntable 22, and the welding joint is ground under the grinding of the grinding turntable 22.

[0041] After placing the copper wire, push the control wheel 34 towards the welding joint of the copper wire. Due to the fixation of the push rack 4, when the meshing rack 41 located on the clamping block 36 moves towards the push rack 4, it is blocked by the push rack 4, causing the meshing rack 41 to move away from the welding joint relative to the clamping block 36. And due to the inclination of the teeth on the rack, the meshing rack 41 moves closer to the copper wire. When the control wheel 34 rotates, it drives the rotating gear 42 to rotate. And because the rotating gear 42 meshes with the driven gear 44, the rotating roller 43 rotates, causing the connecting block 3 on the side away from this connecting block 3 to rotate synchronously with this connecting block 3, synchronously driving the copper wire to rotate. And when the grinding turntable 22 grinds the copper wire, the cleaning brush bristles 63 on the rotating roller 43 clean the grinding turntable 22.

[0042] When rotating the control rotating wheel 34, it is necessary to pull the control rotating wheel 34 to move the abutting block 5 on the control rotating wheel 34 out of the abutting groove 51. When it is necessary to fix the control rotating wheel 34, push the control rotating wheel 34 to move it towards the position of the sliding block 31, and move the abutting block 5 into the abutting groove 51 to fix the control rotating wheel 34. When rotating the control rotating wheel 34, the limiting block 54 on the control rotating wheel 34 rotates with the control rotating wheel 34, and after rotating 180 degrees, it abuts against the blocking block 53 and pushes the control slider 52 to move downward. When reversing the control rotating wheel 34, the limiting block 54 reverses, driving the control rotating wheel 34 to rotate, so that the limiting block 54 rotates 180 degrees in the reverse direction and abuts against the blocking block 53, and pushes the control slider 52 to move upward.

[0043] Place the two copper wires to be welded together on the auxiliary rotating rollers 62 at both ends respectively. When it is necessary to drive the copper wires to rotate, the auxiliary rotating rollers 62 can provide a certain supporting force for the copper wires and will not affect the rotation of the copper wires.

[0044] When polishing the surface of the copper wire, since the diameters of the welding joints are different, when polishing the surface of the copper wire, the distance between the welding joint of the copper wire and the polishing turntable 22 can be adjusted by rotating the adjusting rotating wheel 74. At the same time, due to the different diameters, after polishing the area with a larger diameter, when rotating the copper wire, due to the lack of support at the welding joint, the force of the tension spring 73 is greater than the supporting force at the welding joint, causing the tension spring 73 to drive the sliding block 31 to move towards the side close to the polishing turntable 22. When the sliding block 31 moves, the buffer pad 72 buffers in the buffer oil cylinder 71 to reduce the over-polishing of the welding joint of the copper wire caused by direct movement.

[0045] In this embodiment, the copper wire is firmly fixed by precise clamping, and the copper wire is skillfully driven to rotate during the polishing process. This method can not only ensure that the polishing work at the welding joint is carried out evenly and efficiently, but also largely avoid unnecessary damage to the copper wire. This operation method ensures the accuracy during the polishing process, enables the welding point to reach the expected smoothness and dimensional requirements, while keeping the original structure and shape of the copper wire undamaged. In addition, this method of rotating polishing significantly reduces the labor intensity of the operator, makes the long-term work easier, thus improving the overall safety of the working environment. It enhances the mechanical properties and electrical conductivity of the welded joint, and also makes its appearance more beautiful, meeting the high-standard process requirements, and providing a solid guarantee for the overall quality and service life of the welded part.

[0046] In this embodiment, when grinding the welded joint of the copper wire, pulling both ends of the welded joint to straighten the copper wire can bring many benefits: First, this can make the grinding force evenly distributed, improve the grinding accuracy, and avoid uneven grinding caused by the bending of the copper wire. Second, the straightened copper wire helps to fix the grinding area, facilitating the operator to precisely control the grinding position and force, and reducing the damage to the copper wire. At the same time, this operation method improves the convenience and efficiency of grinding, reduces the need for repeated grinding, maintains the original shape of the copper wire, and reduces the physical consumption and fatigue of the operator. Finally, the straightened copper wire is more stable during the grinding process, improving the safety of the operation, avoiding the potential injury risk caused by the movement of the copper wire, and thus comprehensively improving the quality and safety of the grinding work.

[0047] In this embodiment, when rotating and grinding the welded copper wire, by restricting the rotation angle, precise control of the grinding position and range can be achieved, avoiding over-grinding or omission, while maintaining the original shape and structure of the copper wire and preventing deformation caused by excessive rotation. Such an operation not only reduces the potential damage to the copper wire or solder near the welding point, protecting the integrity of the welded part, but also improves the consistency of the product during batch grinding. In addition, restricting the rotation angle can save grinding time, improve work efficiency, and enhance the safety of the operation, preventing the copper wire from loosening during the grinding process. It is convenient for the operator to check the grinding effect and ensure that each welding point meets the predetermined grinding standard, thus comprehensively improving the grinding accuracy, efficiency, and safety performance.

[0048] The implementation principle of a copper wire surface grinding and processing device in the embodiment of the present application is as follows: After the copper wire is welded, the copper wire is moved to the placement groove 33, and the welded joint of the copper wire is driven to move to the middle position between the two connecting blocks 3. The clamping block 36 clamps the copper wire, and after clamping, the rotation motor 21 is started, so that the output shaft of the rotation motor 21 rotates. The rotation of the output shaft of the rotation motor 21 drives the grinding turntable 22 to rotate, so that the grinding turntable 22 grinds the welded joint close to the grinding turntable 22. When grinding to a certain extent, by driving the control runner 34 to rotate, the axial side walls of the welded joint of the copper wire are all rotated to the end close to the grinding turntable 22, and the welded joint is ground under the grinding of the grinding turntable 22.

[0049] After placing the copper wire, push the control rotating wheel 34 towards the copper wire welding point. Due to the fixation of the push rack 4, when the meshing rack 41 located on the clamping block 36 moves towards the push rack 4, it is blocked by the push rack 4, causing the meshing rack 41 to move away from the welding point relative to the clamping block 36. And due to the inclination of the teeth on the rack, the meshing rack 41 moves closer to the copper wire. When the control rotating wheel 34 rotates, it drives the rotating gear 42 to rotate. And because the rotating gear 42 meshes with the driven gear 44, the rotating roller 43 rotates, causing the connecting block 3 on the side away from the connecting block 3 to rotate synchronously with the connecting block 3, synchronously driving the copper wire to rotate. And when the grinding turntable 22 grinds the copper wire, the cleaning brush hairs 63 on the rotating roller 43 clean the grinding turntable 22.

[0050] When rotating the control rotating wheel 34, it is necessary to pull the control rotating wheel 34 so that the abutting block 5 on the control rotating wheel 34 moves out of the abutting groove 51. When it is necessary to fix the control rotating wheel 34, push the control rotating wheel 34 so that the control rotating wheel 34 moves towards the position of the sliding block 31, and make the abutting block 5 move into the abutting groove 51 to fix the control rotating wheel 34. When rotating the control rotating wheel 34, the limiting block 54 on the control rotating wheel 34 rotates with the control rotating wheel 34, and after rotating 180 degrees, it abuts against the blocking block 53 and pushes the control slider 52 to move downward. When reversing the control rotating wheel 34, the limiting block 54 reverses, driving the control rotating wheel 34 to rotate, so that the limiting block 54 reversely rotates 180 degrees and abuts against the blocking block 53, and pushes the control slider 52 to move upward.

[0051] Place the two copper wires to be welded together on the auxiliary rotating rollers 62 at both ends respectively. When it is necessary to drive the copper wire to rotate, the auxiliary rotating rollers 62 can provide a certain supporting force for the copper wire and will not affect the rotation of the copper wire.

[0052] When grinding the surface of the copper wire, due to the different diameters of the welding points, when grinding the surface of the copper wire, the distance between the copper wire welding point and the grinding turntable 22 can be adjusted by rotating the adjusting rotating wheel 74. At the same time, due to the different diameters, after grinding the area with a larger diameter, when rotating the copper wire, due to the lack of support at the welding point, the force of the tension spring 73 is greater than the supporting force at the welding point, causing the tension spring 73 to drive the sliding block 31 to move towards the side close to the grinding turntable 22. When the sliding block 31 moves, the buffer pad 72 buffers in the buffer oil cylinder 71 to reduce the situation of excessive grinding at the copper wire welding point caused by direct movement.

[0053] The above are the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
