Description

Technical Field

[0001] This invention relates to the field of copper rod processing technology, specifically to an external surface polishing device for copper rod processing. Background Technology

[0002] The external surface polishing device for copper rod processing is a piece of equipment specifically designed for the surface treatment of copper rods. It aims to effectively remove surface oxide layers, burrs, and irregular textures through mechanical, chemical, or electrochemical methods, ensuring a smooth and bright surface.

[0003] Chinese patent publication number CN222843843U discloses an intelligent polishing device for the outer surface of copper rods used in high-efficiency processing. The device includes a body, with the top of the body fixedly connected to the bottom of a polishing wheel and the top of the body fixedly connected to the bottom of a placement wheel. The body is equipped with a positioning mechanism to assist in the polishing and positioning of the copper rod. This positioning mechanism includes a safety mechanism. The positioning mechanism includes a sliding rod, the side wall of which is slidably connected to the inner wall of the body. This intelligent polishing device for the outer surface of copper rods uses a positioning mechanism to control the position of a connecting plate vertically by using the sliding rod. A stabilizing wheel is provided on the inner wall of the connecting plate. The stabilizing wheel works in conjunction with the placement wheel to control and stabilize the position of the copper rod. A return spring at the bottom of the sliding rod provides downward pressure to the connecting plate. This mechanism enables the copper rod to maintain overall rotational stability during polishing.

[0004] However, current polishing devices have the following problems: When polishing copper rods, some longer copper rods do not have a large degree of curvature. If a special straightening device is used for straightening, the straightening effect may be negligible. Furthermore, the time, energy, and human resources spent on using the straightening device may be excessive, as the straightening operation does not produce significant improvement and instead wastes unnecessary time and resources. As a result, the clamped copper rod is in a bent state. Due to the different surface curvature of the bent copper rod, the contact between the polishing tool and the surface is uneven, resulting in over- or under-polishing in some areas, which affects the overall surface quality. Therefore, we propose an external surface polishing device for copper rod processing. Summary of the Invention

[0008] According to the above technical solution, the side of the contact block near the support block is provided with a rough surface, and the support block is located on the displacement trajectory of the rough surface of the contact block.

[0009] According to the above technical solution, the clamping assembly includes a bidirectional threaded rod, both ends of which are rotatably connected to the inner wall of the worktable and driven by a second motor. The second motor is fixed to the worktable. Two threaded sleeves are threadedly connected to the circumferential surfaces of the bidirectional threaded rod with opposite thread directions. The two threaded sleeves are the moving ends of the clamping assembly. The rotating assembly includes a rotating block, which is rotatably connected to the side of a support block. An elastic telescopic rod is fixedly connected to the side of the rotating block. A fifth motor is fixedly connected to the side of the clamping block. One end of the elastic telescopic rod is fixedly connected to the output shaft of the fifth motor.

[0010] According to the above technical solution, the bottom of the support block is in contact with the top of the U-shaped support arc block, and the bottom of the rotating block is in contact with the top of the U-shaped support arc block.

[0011] According to the above technical solution, the top of the movable block is provided with an anti-misalignment device, which includes a connecting block. The bottom of the connecting block is slidably connected to the top of the movable block. A vertical rod is fixedly connected to the bottom of the connecting block on the side away from the movable block. A fixing block is fixedly connected to the outer wall of the support block.

[0012] According to the above technical solution, the vertical rod is slidably connected to the inner wall of the spiral-shaped block.

[0013] According to the above technical solution, a support device is provided on the outer wall of the support block. The support device includes two fixing plates, the sides of which are fixedly connected to the outer wall of the support block. An electric push rod three is hinged to the side of the support block. A connecting plate is hinged to the telescopic end of the electric push rod three. A support plate is fixedly connected to the side of the connecting plate. A support block is fixedly connected to the outer wall of the support block. The bottom of the connecting plate is rotatably connected to the side of the support block.

[0014] This invention provides an outer surface polishing device for processing copper rods. It has the following beneficial effects:

[0015] (1) The present invention uses the cooperation of a support block, a U-shaped block, a contact block, a moving block, an electric push rod one, a loop block, a U-shaped support arc block, an electric push rod two, and an arc-shaped pressure block to make the movement of the loop block drive the contact block to re-abut against the support block through the moving block, thereby fixing the support block. This avoids the problem that when polishing copper rods, the copper rods are in a bent state, which leads to uneven contact between the polishing tool and the surface, which may result in over- or under-polishing in some areas and affect the overall surface quality. At the same time, the cooperation of the rotating block, the U-shaped support arc block, and the arc-shaped pressure block makes the rotation of the rotating block drive the copper rod to rotate, thereby achieving comprehensive polishing. At the same time, the copper rod is restricted by the two rotating blocks, the U-shaped support arc block and the arc-shaped pressure block during the rotation process, so the copper rod is always in a straight state when rotating and will not bend again due to the elasticity of the copper rod itself.

[0016] (2) By setting up an anti-misalignment device, the present invention enables the connection block, vertical rod, fixed block, elastic telescopic rod II, notched ring, L-shaped plate, and spiral inclined block to work together so that the movement of the L-shaped plate will drive the notched ring to move, thereby moving the notched ring to the outer wall of the copper rod close to the rotating block. This avoids the problem that the end of the copper rod close to the rotating block will shift when it is subjected to the pressure of the arc-shaped pressure block, resulting in the overall position of the copper rod shifting. At the same time, by working together with the moving block, connecting block, vertical rod, spiral inclined block, L-shaped plate, and notched ring, the reset of the moving block will drive the connection block, vertical rod, spiral inclined block, L-shaped plate, and notched ring to reset, so that the notched ring is no longer located on the outer wall of the copper rod close to the rotating block. This avoids the copper rod being affected by the notched ring during the polishing process, resulting in incomplete polishing.

[0017] (3) The present invention, through the setting of the support device, enables the fixed plate, electric push rod, connecting plate, support plate and support block to cooperate so that the rotation of the connecting plate will drive the support plate to contact the copper rod, so that the copper rod is always in the position of the rotating block, thereby avoiding the problem that the notched ring cannot move to the copper rod due to the deviation of the copper rod near the rotating block; at the same time, through the cooperation of the notched ring, support plate, rotating block, arc-shaped pressure block and U-shaped support arc block, when the notched ring and support plate support the copper rod near the rotating block at the same time, the stability of the copper rod on the U-shaped support arc block can be further enhanced, so that the arc-shaped pressure block can better straighten the copper rod.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figure 1 - Figure 7One embodiment of the present invention is: a copper rod processing outer surface polishing device, including a worktable 1, a clamping assembly 2 for clamping the copper rod provided on the inner wall of the worktable 1, a moving assembly 3 provided on the inner wall of the worktable 1, the moving assembly 3 consisting of a motor, a screw, and a screw sleeve, which is prior art and therefore will not be described in detail. A rotating assembly 5 for rotating the copper rod is provided on the side of the clamping block 23, and a polishing assembly 4 for polishing the copper rod is provided at the moving end of the moving assembly 3. The polishing assembly 4 consists of an electric push rod, a connecting bracket, a motor, a rotating rod, and a polishing wheel, which is prior art and therefore will not be described in detail. The moving assembly 3 is used to control the movement of the polishing assembly 4. An anti-bending device 6 is provided on the inner wall of the clamping block 23, the anti-bending device 6 including a support Block 61, a support block 61, is slidably mounted on the inner wall of clamping block 23. A spring is provided between the support block 61 and clamping block 23. An abutment block 63 is slidably mounted on the outer wall of clamping block 23. A moving block 64 is fixedly connected to the side of the abutment block 63. An electric push rod 65 is fixedly connected to the top of worktable 1. A U-shaped block 66 is fixedly connected to the telescopic end of the electric push rod 65. The moving block 64 is slidably connected to the inner wall of the U-shaped block 66. A U-shaped support arc block 67 is fixedly connected to the top of the inner wall of worktable 1. An electric push rod 68 is fixedly connected to the upper side of worktable 1. An arc-shaped pressure block 69 is fixedly connected to the telescopic end of the electric push rod 68. A U-shaped block 69 is fixedly connected to the side of clamping block 23 to limit the movement distance of the abutment block 63. 2. The side of the contact block 63 near the support block 61 is roughened. The support block 61 is located on the displacement trajectory of the roughened surface of the contact block 63. The clamping assembly 2 includes a bidirectional threaded rod 21. Both ends of the bidirectional threaded rod 21 are rotatably connected to the inner wall of the worktable 1 and are driven by a motor 2. The motor 2 is fixed on the worktable 1. Two threaded sleeves 22 are threadedly connected to the circumferential surfaces of the bidirectional threaded rod 21 with opposite thread directions. The two threaded sleeves 22 are the moving ends of the clamping assembly 2. The rotating assembly 5 includes a rotating block 52. The rotating block 52 is rotatably connected to the side of the support block 61. An elastic telescopic rod 51 is fixedly connected to the side of the rotating block 52. A motor 5 is fixedly connected to the side of the clamping block 23. One end of the elastic telescopic rod 51 is fixedly connected to the motor 5. On the output shaft, the bottom of the support block 61 contacts the top of the U-shaped support arc block 67, and the bottom of the rotating block 52 contacts the top of the U-shaped support arc block 67. Through this structure, the movement of the loop block 66 will cause the abutment block 63 to re-abut against the support block 61 via the moving block 64, thus fixing the support block 61. This avoids the problem of uneven contact between the polishing tool and the surface during polishing of the copper rod, which could lead to over- or under-polishing in certain areas and affect the overall surface quality, due to the copper rod being in a bent state. Furthermore, during rotation, the copper rod remains straight because it is constrained by the two rotating blocks 52, the U-shaped support arc block 67, and the arc-shaped pressure block 69.It will not bend again due to the elasticity of the copper rod itself.

[0029] A misalignment prevention device 7 is provided on the top of the movable block 64. The misalignment prevention device 7 includes a connecting block 71, the bottom of which is slidably connected to the top of the movable block 64. A vertical rod 72 is fixedly connected to the bottom of the connecting block 71 on the side away from the movable block 64. A fixing block 73 is fixedly connected to the outer wall of the support block 61. An elastic telescopic rod 74 is fixedly connected to the side of the fixing block 73. A notched ring 75 is fixedly connected to one end of the elastic telescopic rod 74. An L-shaped plate 76 is fixedly connected to the side of the notched ring 75. A spiral inclined block 77 is fixedly connected to the side of the L-shaped plate 76. The vertical rod 72 is slidably connected to the inner wall of the spiral inclined block 77. Through the above-mentioned structure... The structure is designed so that the movement of the L-shaped plate 76 will cause the notched ring 75 to move, thus moving the notched ring 75 to the outer wall of the copper rod near the rotating block 52. This prevents the end of the copper rod near the rotating block 52 from shifting when it is subjected to the pressure of the arc-shaped pressure block 69, which would cause the overall position of the copper rod to shift. At the same time, the reset of the moving block 64 will cause the connecting block 71, the vertical rod 72, the spiral inclined block 77, the L-shaped plate 76, and the notched ring 75 to reset, so that the notched ring 75 is no longer located on the outer wall of the copper rod near the rotating block 52. This prevents the copper rod from being affected by the notched ring 75 during the polishing process, which would result in incomplete polishing.

[0030] In use, when placing the copper rod to be polished and bent onto the U-shaped support block 67, with the bent surface of the copper rod facing upwards, the operator starts the motor corresponding to the bidirectional threaded rod 21. The output shaft of the motor causes the bidirectional threaded rod 21 to rotate. The rotation of the bidirectional threaded rod 21 causes the two threaded sleeves 22 to move towards the copper rod. The movement of the two threaded sleeves 22 drives the clamping block 23 to move. The movement of the clamping block 23 drives the abutment block 63 and the support block 61 to move. The movement of the support block 61 drives the rotating block 52 to clamp the copper rod. Only after clamping is complete do the operator release the copper rod and then proceed with the work. When the operator activates electric push rod 2 (68), its telescopic end pushes the arc-shaped pressure block 69 to straighten the bent copper rod. Simultaneously, electric push rod 1 (65) is activated. Its telescopic end moves the U-shaped block 66 away from the U-shaped support arc block 67. This movement of the U-shaped block 66, via the moving block 64, causes the abutment block 63 to no longer contact the support block 61. Therefore, when the arc-shaped pressure block 69 straightens the bent copper rod, both ends of the copper rod push the two rotating blocks 52 towards their respective clamping blocks 23. This movement of the rotating blocks 52 compresses the elastic telescopic rod 1 (51), and simultaneously... The movement of block 52 will cause the support block 61 to move. The movement of support block 61 will compress the elastic force. After the bent copper rod is straightened, the electric push rod 65 will be restarted. The telescopic end of the electric push rod 65 will drive the U-shaped block 66 to move towards the U-shaped support arc block 67. The movement of the U-shaped block 66 will cause the abutment block 63 to abut against the support block 61 again through the moving block 64, thus fixing the support block 61. Therefore, it avoids the uneven contact between the polishing tool and the surface caused by the bent state of the clamped copper rod during polishing, which may lead to over- or under-polishing in some areas and affect the overall surface quality. The issue of quantity is addressed by cooperating with the moving component 3 and the polishing component 4 to polish the copper rod. During the polishing process, the motor 5 corresponding to the elastic telescopic rod 51 is activated. The output shaft of the motor 5 causes the elastic telescopic rod 51 to rotate. The rotation of the elastic telescopic rod 51 drives the rotating block 52 to rotate, which in turn drives the copper rod to rotate, thus achieving comprehensive polishing. At the same time, during the rotation of the copper rod, it is restricted by the two rotating blocks 52, the U-shaped support arc block 67, and the arc-shaped pressure block 69. Therefore, the copper rod remains in a straight state during rotation and will not bend again due to its own elasticity.

[0031] When the moving block 64 causes the abutting block 63 to no longer abut against the supporting block 61, the movement of the moving block 64 will cause the connecting block 71 to move. The movement of the connecting block 71 will cause the vertical rod 72 to move along the inner wall of the spiral inclined block 77, thereby causing the spiral inclined block 77 to move the L-shaped plate 76 away from the clamping block 23. The movement of the L-shaped plate 76 will cause the notched ring 75 to move, thereby moving the notched ring 75 to the outer wall of the copper rod close to the rotating block 52, thus preventing the copper rod from approaching the rotating block when subjected to the pressure of the arc-shaped pressure block 69. One end of 52 will shift, causing the overall position of the copper rod to shift. When the notched ring 75 moves, it will stretch the elastic telescopic rod 74. When the copper rod is pressed, and when the moving block 64 drives the abutment block 63 to reset, the reset of the moving block 64 will drive the connecting block 71, the vertical rod 72, the spiral inclined block 77, the L-shaped plate 76, and the notched ring 75 to reset. This will prevent the notched ring 75 from being located on the outer wall of the copper rod close to the rotating block 52, thus avoiding the copper rod being affected by the notched ring 75 during the polishing process, which would result in incomplete polishing.

[0032] It should be noted that the side of the clamping block 23 has a slot that allows the support block 61 to move all components in the anti-misalignment device 7.

[0033] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, a support device 8 is provided on the outer wall of the support block 61. The support device 8 includes two fixing plates 81. The sides of the two fixing plates 81 are fixedly connected to the outer wall of the support block 61. An electric push rod 82 is hinged to the side of the support block 61. A connecting plate 83 is hinged to the telescopic end of the electric push rod 82. A support plate 84 is fixedly connected to the side of the connecting plate 83. A support block 85 is fixedly connected to the outer wall of the support block 61. The bottom of the connecting plate 83 is rotatably connected to the side of the support block 85. With the above structure, the rotation of the connecting plate 83 will cause the support plate 84 to abut against the copper rod, so that the copper rod is always in the position of the rotating block 52, thereby avoiding the problem that the position of the copper rod near the rotating block 52 is deviated, which would prevent the notched ring 75 from moving to the copper rod.

[0034] During use, before the arc-shaped pressure block 69 presses down on the copper rod, the electric push rod 3 82 is activated. The telescopic end of the electric push rod 3 82 will push the connecting plate 83 to move and rotate along the side of the support block 85. The rotation of the connecting plate 83 will cause the support plate 84 to contact the copper rod, so that the copper rod is always in the position of the rotating block 52, thus avoiding the problem that the notched ring 75 cannot move to the copper rod due to the deviation of the copper rod near the rotating block 52. When the notched ring 75 and the support plate 84 support the end of the copper rod near the rotating block 52 at the same time, the stability of the copper rod on the U-shaped support arc block 67 can be further enhanced, so that the arc-shaped pressure block 69 can press the copper rod straighter.

[0035] It should be noted that the side of the clamping block 23 has a slot that allows the support block 61 to move all components in the support device 8.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
