Description

Technical Field

[0001] The utility model relates to the technical field of copper bushing processing, in particular to a clamp used for copper bushing outer circle processing. Background Art

[0002] A bushing generally refers to a ring sleeve that acts as a gasket. In moving parts, long-term friction causes wear of parts. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. The copper bushing has high requirements on the smoothness of the outer circle and the roundness of the circle, and the side wall of the bushing is thin. During the processing of the bushing, the inner wall of the bushing needs to be supported by a fixture to achieve the purpose of clamping and fixing, which is convenient for processing the outer side of the bushing.

[0003] However, the existing copper bushing clamps usually clamp the outside, and the clamping part of the clamp will block the outer surface of the copper bushing. If the outer surface of the copper bushing is processed, the part clamped by the clamp cannot be processed. The copper bushing needs to be removed and the position of the copper bushing needs to be adjusted so that the clamped part of the copper bushing is offset from the clamp before processing can continue, which reduces the processing speed of the copper bushing. Therefore, a clamp for outer circle processing of the copper bushing is proposed. Utility Model Content

The front side of the rotating column 9 is fixedly provided with a rotating seat 10, and the front side of the rotating seat 10 is overlapped with a cover plate 22. The inner overlap of the cover plate 22 is provided with a bolt 23. The threaded end of the bolt 23 penetrates the cover plate 22 and extends to the inside of the rotating seat 10 and is threadedly arranged with the rotating seat 10. Through the cooperation of the cover plate 22 and the bolt 23, the connection between the bevel gear 13 and the bevel gear 2 14 is Isolation protection is performed at the place to avoid foreign matter being mixed between the bevel gear 13 and the bevel gear 2 14, which may cause reduced accuracy or damage, and reduce the failure rate of the fixture. A rotating assembly is arranged inside the rotating column 9, and the rotating column 9 is provided with a bevel gear 13 through the rotating assembly. The rotating assembly includes a motor 2 11 fixedly arranged inside the rotating column 9, and a rotating rod 2 12 is fixedly arranged at the output end of the motor 2 11. The rotating rod 2 12 is rotatably arranged with the inner wall of the rotating seat 10, and the surface of the rotating rod 2 12 is fixedly arranged with the inner wall of the bevel gear 13. The rotating rod 2 12 is driven by the motor 2 11 to rotate forward and reverse, so that the three bevel gears 2 14 can be driven at the same time according to the size of the inner sleeve, so that the three bevel gears 2 14 can be driven at the same time. The three threaded rods 15 rotate, and the three threaded rods 15 drive the three threaded blocks 16 to approach the inner wall of the copper bushing until the three support bars 21 contact the inner wall of the copper bushing at the same time, thereby ensuring the stable clamping of the inner wall of the copper bushing and avoiding the deformation of the inner wall of the copper bushing due to uneven force. A moving component is arranged inside the bevel gear 13, and the moving component includes a bevel gear 2 14 meshingly arranged inside the bevel gear 13, and the surface of the bevel gear 2 14 is fixedly provided with a threaded rod 15, and the surface of the threaded rod 15 is rotatably arranged with the inner wall of the rotating seat 10, and the surface of the threaded rod 15 is threadedly provided with a threaded block 16, and the surface of the threaded block 16 is slidably arranged with the inner wall of the rotating seat 10, and the front side of the threaded block 16 is fixedly arranged with the rear side of the support frame 17.The threaded rod 15 is driven to rotate forward and reversely by the bevel gear 2 14, so that the threaded rod 15 drives the threaded blocks 16 to move closer or farther away from each other, so as to facilitate stable clamping according to the size of the copper bushing. The bevel gear 13 is provided with a support frame 17 through a moving component, and a support component is provided inside the support frame 17. The support component includes a pressure sensor 18 fixedly arranged on the inner wall of the support frame 17, and a limit plate 19 is fixedly arranged on the input end of the pressure sensor 18.

The surface of the slider 20 is slidably arranged with the inner wall of the support frame 17, and a support bar 21 is fixedly arranged on the front side of the slider 20. When the copper bushing is clamped, the support bar 21 pushes the slider 20, so that the slider 20 pushes the limit plate 19, so that the limit plate 19 presses the pressure sensor 18, which is convenient for the staff to monitor in real time. The clamping force of the copper bushing can be adjusted in time to avoid the occurrence of large quantities of defective products due to uneven clamping force. The fixture used for the outer circle processing of the copper bushing drives the bevel gear 13 to rotate through the rotating assembly, so that the bevel gear 13 drives the bevel gear 2 14 to rotate, and the bevel gear 2 14 drives the threaded rod 15 to rotate, so that the threaded rod 15 drives the threaded block 16 to approach the inner wall of the copper bushing, so that the support frame 17 and the support assembly can support the inner wall of the copper bushing, preventing the existing copper bushing fixture from clamping the outside, causing the clamping part of the fixture to block the outer surface of the copper bushing.

[0026] When in use: the copper bushing is sleeved on the outside of the three support bars 21, so that the three support bars 21 are all inside the copper bushing, and then the motor 2 11 is started to drive the rotating rod 2 12 to rotate, so that the rotating rod 2 12 drives the bevel gear 1 13 to rotate, and the bevel gear 1 13 drives the bevel gear 2 14 to rotate, so that the bevel gear 2 14 drives the threaded rod 15 to rotate, so that the threaded rod 15 drives the threaded block 16 to move away from the bevel gear 2 14, and the threaded block 16 drives the support frame 17 to approach the inner wall of the copper bushing during the movement, so that the support frame 17 drives the pressure sensor 18, the limit plate 19 and the slider 20 to approach the inner wall of the copper bushing, and when the three sliders 20 drive the three support bars 21 to contact the inner wall of the copper bushing, the support is completed. According to the different sizes of the copper bushing, At the same time, it can be adjusted and adapted quickly. At the same time, after the copper bushing is clamped, the three support bars 21 will generate pressure toward the middle, pressing the slider 20 toward the middle, so that the slider 20 presses the limit plate 19 toward the middle, thereby causing the limit plate 19 to press the pressure sensor 18. The pressure sensor 18 is electrically connected to an external controller through a wire, so that the clamping force exerted on the copper bushing can be viewed in real time for timely adjustment to avoid excessive or insufficient clamping force. When processing, start the motor 4 to drive the rotating rod 5 to rotate, so that the rotating rod 5 can drive the active sprocket 6 to rotate, and the active sprocket 6 drives the chain 7 to rotate, so that the chain 7 drives the driven sprocket 8 to rotate, thereby causing the driven sprocket 8 to drive the rotating column 9 to rotate, thereby rotating the copper bushing for processing.
