Description

Technical Field

[0001] The present application relates to the technical field of copper wire surface polishing, and in particular to a copper wire surface polishing treatment device. Background Art

[0002] During the continuous production process of copper wire, the copper wire may break or need to be replaced with a new copper wire reel. In order to maintain the continuity of production, it is necessary to weld the two ends of the broken copper wire together, or connect the new copper wire to the old copper wire. In addition, in the multi-pass drawing or twisting process, the copper wire may break at the joint after multiple stretching and deformation. Welding can be used to repair the joint to ensure the continued operation of the production line.

[0003] After soldering the copper wire, the soldering joints need to be polished to ensure the smoothness of the surface of the processed material. During this process, the worker needs to hold a polishing tool to polish the soldering joints. During the polishing process, the worker needs to constantly adjust the polishing angle and the contact distance between the polishing tool and the copper wire.

[0004] Referring to the Chinese patent document with publication number CN211867385U, entitled A surface grinding tool for processing copper alloy welding materials, the device drives the first screw to rotate by a first motor, so that the first movable block moves, driving the connecting cover, the support rod and the grinding motor to move, thereby eliminating the need for manual hand-held grinding back and forth, saving time and effort. When the second movable block is driven to move by the second motor, the movable block drives the connecting rod to pull or push the grinding motor, causing the support rod to swing, adjusting the grinding angle of the grinding motor, and making the grinding of the grinding motor more suitable for processing materials with side grinding.

[0005] According to the above technical solution, when grinding the welding parts of the copper wire, the staff needs to hold the grinding tools to grind the welding parts of the copper wire. When grinding the copper wire, the two ends of the copper wire welding parts need to be pulled to keep the copper wire flat to facilitate observation of the degree of grinding. At the same time, the staff needs to pay attention to the depth of grinding when grinding. If the operation is improper, it is easy to cause excessive grinding of the copper wire welding parts, affecting the quality. In addition, in the process of straightening the copper wire, multiple people are required to cooperate, affecting work efficiency. Summary of the Invention

[0006] In view of this, the present application provides a copper wire surface grinding processing device, which aims to solve the problem of inconsistent grinding depth when grinding the welding parts of the copper wire.

[0007] A copper wire surface polishing processing device provided in the present application adopts the following technical solution, including a support frame and a polishing mechanism arranged on the support frame for polishing 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 storage groove is provided on the rotating block, a control wheel is slidably connected to the rotating block, a connecting spring is fixedly connected to the control wheel, a clamping block is fixedly connected to the end of the connecting spring away from the control wheel, and the clamping block is arranged inside the rotating block.

[0008] This device polishes the surface of a copper wire using a polishing mechanism on a support frame. First, the copper wire is placed in the slot of the rotating block and secured. Then, the control wheel is operated, and the spring-loaded clamping block is pulled closed, clamping the wire. Next, the polishing mechanism is activated, and the rotating block rotates and polishes the copper wire. The polishing effect can be controlled by fine-tuning the clamping force and the rotation of the rotating block using the control wheel. Finally, polishing is stopped and the control wheel is reversed to open the clamping block, releasing the polished copper wire.

[0009] Clamping and rotating the copper wire offers numerous benefits to the welded wire. First, placing and securing the wire in the rotating block's slot ensures its stability during the polishing process, preventing uneven polishing or damage caused by wire movement. Second, operating the control wheel, which pulls the clamping block closed via a spring, secures the wire, ensuring close contact between the wire and the polishing mechanism, improving polishing efficiency and quality. Next, starting the polishing mechanism and rotating the wire with the rotating block ensures uniform contact between the wire surface and the polishing mechanism, preventing damage from excessive polishing in certain areas. By fine-tuning the clamping force of the wheel and the rotation of the rotating block, the polishing intensity and effect can be controlled to achieve the desired surface roughness, improving weld quality. Finally, stopping polishing and reversing the control wheel to open the clamping block and release the polished wire prevents deformation or damage from prolonged clamping.

[0010] Optionally, a pushing rack is fixedly connected to the rotating block, a pushing rack is fixedly connected to the rotating block, and an engaging rack is fixedly connected to the clamping block. The pushing rack can engage with the engaging rack, and when the control wheel moves toward the rotating block, the pushing rack can push the engaging rack to move toward the outer wall of the copper wire.

[0011] When the control wheel moves toward the rotating block, it pushes the rack to drive the meshing rack to move toward 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 wheel, the clamping force can be precisely controlled to avoid damaging the copper wire or causing it to slip, thereby ensuring the quality of polishing; second, the gear rack mechanism has strong rigidity and high stability, which prevents the copper wire from loosening or shifting during high-speed rotation and polishing; third, the mechanism has high transmission efficiency and can respond to operations quickly, thereby improving polishing efficiency; finally, by uniformly clamping the copper wire, excessive local force is avoided, effectively protecting the copper wire. In summary, the gear rack clamping mechanism significantly improves the quality and efficiency of copper wire polishing by precisely controlling the clamping force, enhancing stability, improving efficiency, and protecting the copper wire, ensuring that the surface of the polished copper wire is uniform and smooth, meeting the requirements of subsequent processes.

[0013] By clamping the copper wire and driving it to rotate, the copper wire can be ensured to remain stable during the grinding process, thereby improving the grinding efficiency and quality, making the surface of the copper wire reach the expected roughness, improving the welding quality, and avoiding deformation or damage of the copper wire due to long-term clamping.

[0014] Optionally, an abutment block is fixedly connected to the control wheel, and an abutment groove is provided on the sliding block, and the abutment block can extend into the abutment groove to fix the control wheel.

[0017] Optionally, the grinding mechanism includes a rotating motor fixedly connected to a support frame, and a grinding turntable is fixedly connected to the output shaft of the rotating motor. The grinding turntable is used to grind the welding points of the copper wire, and the grinding turntable is arranged in the middle position of the two connecting blocks, and the grinding turntable and the connecting blocks are rotatably connected.

[0018] Optionally, a buffer rod is slidably connected to the sliding block, a buffer oil cylinder is provided on the connecting block, a buffer pad is fixedly connected to the buffer rod, and a tension spring is fixedly connected to the sliding block, and the tension spring is fixedly connected to the connecting block at one end away from the sliding block.

[0019] By buffering the sliding block, the copper wire damage caused by excessive grinding force during the grinding process can be avoided to a certain extent, especially at the welding point where the diameter changes. It can also reduce the vibration during the grinding process, thereby improving the grinding accuracy.

This ensures close contact between the wire and the polishing mechanism, improving polishing efficiency and quality. Next, starting the polishing mechanism and rotating the wire with the rotating block ensures uniform contact between the wire surface and the polishing mechanism, preventing damage from excessive polishing in certain areas. By fine-tuning the clamping force of the wheel and the rotation of the rotating block, the polishing intensity and effect can be controlled to achieve the desired surface roughness, improving weld quality. Finally, stopping polishing and reversing the control wheel to open the clamping block and release the polished wire prevents deformation or damage from prolonged clamping.

By installing a cleaning brush on the grinding wheel, you can promptly remove copper chips, oxide scale and other residues generated during the grinding process, keeping the work area clean, preventing cross-contamination, improving grinding efficiency, and extending the life of the grinding wheel.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application Figure 1-Figure 7, the technical solutions of the embodiments of the present application are clearly and completely described. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0035] like Figure 1 As shown, this embodiment provides a copper wire surface grinding processing device including a support frame 1, a grinding mechanism 2, a rotating clamping mechanism, a linkage stretching mechanism, a limiting mechanism and a buffer mechanism. The support frame 1 is placed on a horizontal plane, the grinding mechanism 2 is used to grind the welding part 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 straighten during the rotation of the rotating clamping mechanism, the limiting mechanism is used to limit the rotation angle of the rotating clamping mechanism, and the buffer mechanism is used to reduce the occurrence of excessive grinding due to inconsistent diameters of the welding part.

[0036] like Figure 1 and Figure 2 As shown, 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 points of the copper wire.

[0037] When the welding part of the copper wire needs to be polished, the rotating motor 21 is started, and the output shaft of the rotating motor 21 rotates to drive the polishing turntable 22 to rotate, so that the polishing turntable 22 polishes the welding part of the copper wire.

[0038] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the rotating clamping mechanism includes a connecting block 3, a sliding block 31, a rotating block 32, a storage 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, and the rotating block 32 is rotatably connected to the clamping block 36. The storage groove 33 is opened on the rotating block 32, and 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.

[0039] After the copper wire is welded, it is moved into the storage slot 33 and the welded portion of the copper wire is moved to the middle position between the two connecting blocks 3. The clamping block 36 clamps the copper wire and, after clamping, the rotating motor 21 is started to rotate the output shaft of the rotating motor 21. The rotation of the output shaft of the rotating motor 21 drives the grinding turntable 22 to rotate, causing the grinding turntable 22 to grind the welded portion near the grinding turntable 22. After grinding to a certain degree, the control wheel 34 is driven to rotate, causing the axial side walls of the copper wire welded portion to rotate to one end near the grinding turntable 22, and the welding portion is polished under the grinding of the grinding turntable 22.

[0040] like Figure 3 、 Figure 5 and Figure 6 As shown, the linkage stretching mechanism includes a pushing rack 4, an engaging 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 wall of the rotating block 32, the engaging rack 41 is fixedly connected to the sliding block 31, and the engaging rack 41 can engage 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 of two adjacent connecting blocks 3, the driven gear 44 is fixedly connected to the rotating roller 43, and the cleaning brush 63 is fixedly connected to the rotating roller 43.

[0041] After the copper wire is placed, the control wheel 34 is pushed to move toward the copper wire welding position, and due to the fixation of the pushing rack 4, the meshing rack 41 located on the clamping block 36 is blocked by the pushing rack 4 when moving toward the pushing rack 4, so that the meshing rack 41 moves relative to the clamping block 36 toward away from the welding position, and due to the inclination of the teeth on the rack, the meshing rack 41 is further close to the copper wire, and when the control wheel 34 rotates, it drives the rotating gear 42 to rotate, and because the rotating gear 42 and the driven gear 44 are engaged, the rotating roller 43 rotates, so that the connecting block 3 away from the side of the connecting block 3 rotates synchronously with the connecting block 3, and the copper wire is driven to rotate synchronously, and when the grinding turntable 22 grinds the copper wire, the cleaning bristles 63 on the rotating roller 43 clean the grinding turntable 22.

[0042] like Figure 3 and Figure 4 As shown, the limiting mechanism includes an abutment block 5, an abutment groove 51, a control slider 52, a blocking block 53 and a limiting block 54. The abutment block 5 is fixedly connected to the control wheel 34. The abutment groove 51 is opened on the sliding block 31, and the abutment block 5 can extend into the abutment groove 51 to fix the control wheel 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 one hundred and eighty degrees, it will abut against the blocking block 53.

[0043] When the control wheel 34 is rotated, it is necessary to pull the control wheel 34 so that the abutment block 5 on the control wheel 34 moves out of the abutment groove 51. When the control wheel 34 needs to be fixed, the control wheel 34 is pushed to move the control wheel 34 toward the position of the sliding block 31, and the abutment block 5 moves into the abutment groove 51 to fix the control wheel 34. When the control wheel 34 is rotated, the limiting block 54 on the control wheel 34 rotates with the control wheel 34 and abuts against the blocking block 53 after rotating one hundred and eighty degrees, and pushes the control slider 52 to move downward. When the control wheel 34 is reversed, the limiting block 54 reverses, driving the control wheel 34 to rotate, causing the limiting block 54 to rotate in the opposite direction one hundred and eighty degrees and abut against the blocking block 53, and pushing the control slider 52 to move upward.

[0044] Among them, such as Figure 3 As shown, the connecting block 3 is fixedly connected to an auxiliary connecting rod 6, the auxiliary connecting rod 6 is fixedly connected to an auxiliary connecting block 61, the auxiliary connecting block 61 is fixedly connected to an auxiliary roller 62, and the auxiliary roller 62 is used to provide auxiliary support and auxiliary rotation for the copper wire.

[0045] The two copper wires to be welded are placed on the auxiliary rollers 62 at both ends respectively. When the copper wires need to be rotated, the auxiliary rollers 62 can provide a certain supporting force for the copper wires without affecting the rotation of the copper wires.

[0046] like Figure 7 As shown, the buffer mechanism includes a buffer rod 7, a buffer cylinder 71, a buffer pad 72, a tensioning spring 73 and an adjusting wheel 74. The buffer rod 7 is slidably connected to the sliding block 31, the buffer cylinder 71 is arranged on the connecting block 3, the buffer pad 72 is fixedly connected to the buffer rod 7, the tensioning spring 73 is fixedly connected to the sliding block 31, and the end of the tensioning spring 73 away from the sliding block 31 is fixedly connected to the connecting block 3, the adjusting wheel 74 is rotatably connected to the sliding block 31, the adjusting wheel 74 and the buffer rod 7 are connected by a threaded connection, and the adjusting wheel 74 is used to adjust the distance between the sliding block 31 and the buffer rod 7.

[0047] When the surface of the copper wire is polished, due to the different diameters of the welding points, the distance between the copper wire welding points and the polishing turntable 22 can be adjusted by rotating the adjusting wheel 74 when polishing the surface of the copper wire. At the same time, due to the different diameters, after polishing the area with a larger diameter, during the process of rotating the copper wire, due to the lack of support at the welding points, the force of the tensioning spring 73 is greater than the support force of the welding points, so that the tensioning spring 73 drives the sliding block 31 to move toward the side close to the polishing turntable 22. When the sliding block 31 moves, the buffer pad 72 performs a certain buffering in the buffer cylinder 71 to reduce the excessive polishing of the copper wire welding points caused by direct movement. When the present application is in use, after welding the copper wire, the copper wire is moved into the storage slot 33, and the weld of the copper wire is driven to move to the middle position of the two connecting blocks 3. The clamping block 36 clamps the copper wire, and after clamping, the rotating motor 21 is started to rotate the output shaft of the rotating motor 21. 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 weld near the grinding turntable 22. After grinding to a certain extent, the control wheel 34 is driven to rotate so that the axial side walls of the copper wire weld are rotated to one end near the grinding turntable 22, and the welding is polished under the grinding of the grinding turntable 22.

[0048] After the copper wire is placed, the control wheel 34 is pushed to move toward the copper wire welding position, and due to the fixation of the pushing rack 4, the meshing rack 41 located on the clamping block 36 is blocked by the pushing rack 4 when moving toward the pushing rack 4, so that the meshing rack 41 moves relative to the clamping block 36 toward away from the welding position, and due to the inclination of the teeth on the rack, the meshing rack 41 is further close to the copper wire, and when the control wheel 34 rotates, it drives the rotating gear 42 to rotate, and because the rotating gear 42 and the driven gear 44 are engaged, the rotating roller 43 rotates, so that the connecting block 3 away from the side of the connecting block 3 rotates synchronously with the connecting block 3, and the copper wire is driven to rotate synchronously, and when the grinding turntable 22 grinds the copper wire, the cleaning bristles 63 on the rotating roller 43 clean the grinding turntable 22.

[0049] When the control wheel 34 is rotated, it is necessary to pull the control wheel 34 so that the abutment block 5 on the control wheel 34 moves out of the abutment groove 51. When the control wheel 34 needs to be fixed, the control wheel 34 is pushed to move the control wheel 34 toward the position of the sliding block 31, and the abutment block 5 moves into the abutment groove 51 to fix the control wheel 34. When the control wheel 34 is rotated, the limiting block 54 on the control wheel 34 rotates with the control wheel 34 and abuts against the blocking block 53 after rotating one hundred and eighty degrees, and pushes the control slider 52 to move downward. When the control wheel 34 is reversed, the limiting block 54 reverses, driving the control wheel 34 to rotate, causing the limiting block 54 to rotate in the opposite direction one hundred and eighty degrees and abut against the blocking block 53, and pushing the control slider 52 to move upward.

[0050] The two copper wires to be welded are placed on the auxiliary rollers 62 at both ends respectively. When the copper wires need to be rotated, the auxiliary rollers 62 can provide a certain supporting force for the copper wires without affecting the rotation of the copper wires.

[0051] When the surface of the copper wire is polished, due to the different diameters of the welding points, the distance between the copper wire welding points and the polishing turntable 22 can be adjusted by rotating the adjusting wheel 74 when polishing the surface of the copper wire. At the same time, due to the different diameters, after polishing the area with a larger diameter, during the process of rotating the copper wire, due to the lack of support at the welding points, the force of the tensioning spring 73 is greater than the support force of the welding points, so that the tensioning spring 73 drives the sliding block 31 to move toward the side close to the polishing turntable 22. When the sliding block 31 moves, the buffer pad 72 performs a certain buffering in the buffer cylinder 71 to reduce the excessive polishing of the copper wire welding points caused by direct movement.

[0052] In this embodiment, the copper wire is firmly fixed by using precise clamping, and the copper wire is cleverly driven to rotate during the grinding process. This method not only ensures that the grinding work of the weld is carried out evenly and efficiently, but also largely avoids unnecessary damage to the copper wire. This operating method ensures the accuracy of the grinding process, so that the welding point can achieve the expected smoothness and size requirements, while keeping the original structure and shape of the copper wire intact. In addition, this method of rotational grinding significantly reduces the labor intensity of the operator, making long-term work easier, thereby improving the overall safety of the working environment. It improves the mechanical properties and conductivity of the welded joint, and also makes its appearance more beautiful, meets high-standard process requirements, and provides a solid guarantee for the overall quality and service life of the welded part.

[0053] In this embodiment, when polishing the copper wire welding point, pulling the two ends of the welding point to straighten the copper wire can bring many benefits: first, this can make the polishing force evenly distributed, improve the polishing accuracy, and avoid uneven polishing caused by copper wire bending; second, the straightened copper wire helps to fix the polishing area, which is convenient for the operator to accurately control the polishing position and force, and reduce damage to the copper wire; at the same time, this operation method improves the convenience and efficiency of polishing, reduces the need for repeated polishing, maintains the original shape of the copper wire, and reduces the operator's physical exertion and fatigue; finally, the straightened copper wire is more stable during the polishing process, which improves the safety of operation and avoids the potential risk of injury caused by copper wire movement, thereby comprehensively improving the quality and safety of the polishing work.

[0054] In this embodiment, when the copper wire after welding is subjected to rotational grinding, by limiting its rotation angle, precise control of the grinding position and range can be achieved, avoiding excessive grinding or omissions, 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 and protects the integrity of the welding part, but also improves the consistency of the product during the batch grinding process. In addition, limiting the rotation angle can also save grinding time, improve work efficiency, and enhance operational safety by 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, thereby comprehensively improving the accuracy, efficiency and safety of the grinding.

[0055] The working principle of a copper wire surface grinding treatment device in the embodiment of the present application is as follows: after the copper wire is welded, the copper wire is moved into the storage groove 33, and the welded portion of the copper wire is driven to move to the middle position of the two connecting blocks 3. The clamping block 36 clamps the copper wire, and after clamping, the rotating motor 21 is started to rotate the output shaft of the rotating motor 21. 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 portion near the grinding turntable 22. After grinding to a certain extent, the control wheel 34 is driven to rotate, so that the axial side walls of the copper wire welded portion are rotated to one end near the grinding turntable 22, and the welding portion is polished under the grinding of the grinding turntable 22.

[0056] After the copper wire is placed, the control wheel 34 is pushed to move toward the copper wire welding position, and due to the fixation of the pushing rack 4, the meshing rack 41 located on the clamping block 36 is blocked by the pushing rack 4 when moving toward the pushing rack 4, so that the meshing rack 41 moves relative to the clamping block 36 toward away from the welding position, and due to the inclination of the teeth on the rack, the meshing rack 41 is further close to the copper wire, and when the control wheel 34 rotates, it drives the rotating gear 42 to rotate, and because the rotating gear 42 and the driven gear 44 are engaged, the rotating roller 43 rotates, so that the connecting block 3 away from the side of the connecting block 3 rotates synchronously with the connecting block 3, and the copper wire is driven to rotate synchronously, and when the grinding turntable 22 grinds the copper wire, the cleaning bristles 63 on the rotating roller 43 clean the grinding turntable 22.

[0057] When the control wheel 34 is rotated, it is necessary to pull the control wheel 34 so that the abutment block 5 on the control wheel 34 moves out of the abutment groove 51. When the control wheel 34 needs to be fixed, the control wheel 34 is pushed to move the control wheel 34 toward the position of the sliding block 31, and the abutment block 5 moves into the abutment groove 51 to fix the control wheel 34. When the control wheel 34 is rotated, the limiting block 54 on the control wheel 34 rotates with the control wheel 34 and abuts against the blocking block 53 after rotating one hundred and eighty degrees, and pushes the control slider 52 to move downward. When the control wheel 34 is reversed, the limiting block 54 reverses, driving the control wheel 34 to rotate, causing the limiting block 54 to rotate in the opposite direction one hundred and eighty degrees and abut against the blocking block 53, and pushing the control slider 52 to move upward.

[0058] The two copper wires to be welded are placed on the auxiliary rollers 62 at both ends respectively. When the copper wires need to be rotated, the auxiliary rollers 62 can provide a certain supporting force for the copper wires without affecting the rotation of the copper wires.

[0059] When the surface of the copper wire is polished, due to the different diameters of the welding points, the distance between the copper wire welding points and the polishing turntable 22 can be adjusted by rotating the adjusting wheel 74 when polishing the surface of the copper wire. At the same time, due to the different diameters, after polishing the area with a larger diameter, during the process of rotating the copper wire, due to the lack of support at the welding points, the force of the tensioning spring 73 is greater than the support force of the welding points, so that the tensioning spring 73 drives the sliding block 31 to move toward the side close to the polishing turntable 22. When the sliding block 31 moves, the buffer pad 72 performs a certain buffering in the buffer cylinder 71 to reduce the excessive polishing of the copper wire welding points caused by direct movement.

[0060] The above is a preferred embodiment of the present application.
