The implementation conditions used in the examples can be further adjusted according to the specific conditions of the manufacturer, and the implementation conditions not specified are usually the conditions in the conventional experiments.

[0025] A copper alloy surface polishing device, as shown in Figures 1-7 , includes a support bottom plate 1, a support arm 2 fixedly connected to the support bottom plate 1, an AC motor 3 fixedly connected to the support arm 2, a positioning disc 41 fixedly connected to the output shaft of the AC motor 3, a threaded rotating rod 42 threadedly connected to the upper part of the positioning disc 41, a gasket 43 fixedly connected to the lower end of the threaded rotating rod 42, a double-shaft motor 5 fixedly connected to the support bottom plate 1, a mobile polishing mechanism provided on the support bottom plate 1, the mobile polishing mechanism being used for polishing the side wall of a copper bar, a rotary polishing mechanism provided on the support bottom plate 1, the rotary polishing mechanism being used for polishing the top surface and the bottom surface of the copper bar, and the rotary polishing mechanism being connected to the mobile polishing mechanism.

[0026] The mobile polishing mechanism comprises two supporting rods 61, a rotating long rod 62 rotatably connected between the two supporting rods 61, a two-way threaded sleeve 63 fixedly connected to the rotating long rod 62, a transmission assembly 64 connected between one rotating shaft of the double-shaft motor 5 and one side of the rotating long rod 62, a sliding rail 65 fixedly connected to the supporting bottom plate 1, a supporting frame 66 slidably connected to the sliding rail 65, a polishing plate 67 slidably connected to the upper portion of the supporting frame 66, a connecting spring 671 connected between the polishing plate 67 and the supporting frame 66, a threaded block 68 fixedly connected to one side of the supporting frame 66, and the threaded block 68 is threadedly connected with the two-way threaded sleeve 63, an inclined curved rod 69 fixedly connected to the supporting bottom plate 1, and a side circular rod 610 fixedly connected to one side of the polishing plate 67.

[0027] The transmission assembly 64 comprises a transmission wheel one, a transmission wheel two and a transmission belt, the rotating long rod 62 is connected with the transmission wheel one, one rotating shaft of the double-shaft motor 5 is connected with the transmission wheel two, and the transmission belt is wound between the transmission wheel one and the transmission wheel two.

[0028] The rotating polishing mechanism comprises a guide frame 71 fixedly connected to the supporting bottom plate 1, a sliding frame 72 slidably connected to the guide frame 71, a polishing disc 73 rotatably connected to the upper portion of the sliding frame 72, a guide rod 74 fixedly connected to one side of the sliding frame 72, a connecting block 75 fixedly connected to one side of the supporting frame 66, the guide rod 74 penetrating through the connecting block 75, a tension spring 76 connected between the connecting block 75 and the guide rod 74, a supporting plate 77 fixedly connected to the supporting bottom plate 1, a multi-edge rod 78 rotatably connected to the supporting plate 77, the multi-edge rod 78 being connected with the other rotating shaft of the double-shaft motor 5, a linkage assembly 79 connected between the multi-edge rod 78 and the polishing disc 73, the multi-edge rod 78 being used for ensuring the horizontal movement of the linkage assembly 79 while realizing transmission, a clamping frame 710 fixedly connected to one side of the sliding frame 72 away from the guide rod 74, and two ball bearings 711 rotatably connected to the clamping frame 710, the two ball bearings 711 being respectively in contact with two sides of the linkage assembly 79.

[0029] The linkage assembly 79 comprises a driving wheel, a driven wheel and a linkage belt, the multi-edge rod 78 is connected with the driving wheel, the polishing disc 73 is connected with the driven wheel, and the linkage belt is wound between the driving wheel and the driven wheel.

[0030] In actual work, the surface of the copper bar needs to be polished. First, the operator places one end of the copper bar horizontally on the positioning disc 41, then rotates the threaded rotating rod 42, which will drive the gasket 43 to move vertically, thereby causing the gasket 43 to press the one end of the copper bar and fix it. Then the operator starts the alternating current motor 3 first, and then starts the double-shaft motor 5, which rotates in the opposite direction of the alternating current motor 3. The alternating current motor 3 will drive the positioning disc 41 to rotate quickly, which will drive the copper bar to rotate. The rotation of the double-shaft motor 5 will drive the rotating long rod 62 and the polishing disc 73 to rotate through the transmission assembly 64 and the linkage assembly 79, respectively. The rotation of the rotating long rod 62 will drive the bidirectional threaded sleeve 63 to rotate, which will drive the threaded block 68 to move horizontally. Then the horizontal movement of the threaded block 68 will drive the support frame 66 and the polishing plate 67 to move horizontally. The horizontal movement of the polishing plate 67 will first contact the side wall of the copper bar, and then the inclined bent rod 69 will press the side circular rod 610 to drive the polishing plate 67 to move downward, so that the polishing plate 67 generates a pressure on the side wall of the copper bar. Then the polishing plate 67 moving horizontally in combination with the rotating copper bar can polish the side wall of the copper bar. When the support frame 66 moves horizontally towards the support arm 2, it will drive the guide rod 74 to move horizontally through the connecting block 75 and the tension spring 76. The horizontal movement of the guide rod 74 will drive the sliding frame 72 and the polishing disc 73 to move towards the side of the copper bar. The horizontal movement of the sliding frame 72 will drive the clamping frame 710 to move horizontally, thereby driving the linkage assembly 79 to move horizontally, ensuring the transmission of power. The guide bead 84 is used to contact the linkage assembly 79 without interfering with its operation. When the polishing disc 73 contacts the side of the copper bar, the guide frame 71 clamps the sliding frame 72, so that the sliding frame 72 no longer moves towards the support arm 2 with the support frame 66. The tension spring 76 is stretched. In this way, the rotating polishing disc 73 polishes the side of the copper bar. After the copper bar is polished once, the copper bar is removed and placed on the positioning disc 41 to fix the polished side of the copper bar. Then the other side of the copper bar is polished. In this way, the surface of the copper bar can be polished more fully.

[0031] Example 2

[0032] Based on example 1, as Figure 5 and Figure 6As shown, the device further comprises a scraping mechanism arranged on the support base plate 1, which is connected with the sliding frame 72 and used for cleaning impurities on the polishing plate 67 and the polishing disc 73. The scraping mechanism comprises a support rod 81 fixedly connected with the support base plate 1, a rotating block 82 rotatably connected with the support rod 81, a torsion spring 83 connected between the rotating block 82 and the support rod 81, a guide bead 84 fixedly connected with one side of the rotating block 82, an inclined chute rod 85 fixedly connected with one side of the sliding frame 72, a guide groove formed in the inclined chute rod 85, the guide bead 84 located in the guide groove on the inclined chute rod 85, an arc-shaped scraping rod 86 fixedly connected with the rotating block 82, and a straight scraping rod 87 slidably connected with the arc-shaped scraping rod 86.

[0033] When the sliding frame 72, the polishing plate 67 and the polishing disc 73 move horizontally towards the support arm 2, the sliding frame 72 drives the inclined chute rod 85 to move horizontally, the polishing plate 67 moves horizontally by a distance and is scraped by the arc-shaped scraping rod 86 to remove polishing impurities adhered to the lower surface, then one side of the polishing disc 73 contacts the straight scraping rod 87, since the polishing disc 73 rotates, the straight scraping rod 87 removes the impurities on the polishing disc 73 after the polishing disc 73 contacts the straight scraping rod 87, then the polishing disc 73 and the inclined chute rod 85 continue to move horizontally, the reset spring 88 is compressed, the inclined chute rod 85 continues to move horizontally and drives the guide bead 84 and the rotating block 82 to rotate by 90° through the guide groove, the torsion spring 83 is twisted, the rotating block 82 drives the arc-shaped scraping rod 86 and the straight scraping rod 87 to swing downward by 90°, the straight scraping rod 87 swings downward by 90° and is separated from the polishing disc 73, then the polishing disc 73 and the polishing plate 67 continue to move horizontally to polish the surface of the copper bar, when the polishing disc 73 moves horizontally by a distance away from the support arm 2, the guide bead 84 and the rotating block 82 are rotated to reset through the guide groove, and then the arc-shaped scraping rod 86 and the straight scraping rod 87 swing upward to reset, so that the residual impurities on the polishing device can be cleaned in time, and the surface of the copper bar is not easily damaged by the impurities.

[0034] Example 3

[0035] On the basis of Example 2, as Figure 7As shown, the correction mechanism is arranged on the support bottom plate 1, and is used for correcting the position of the copper bar. The correction mechanism comprises a stand 91 fixedly connected to the support bottom plate 1, a rotating frame 92 rotatably connected to the stand 91, a torsion spring 93 connected between the rotating frame 92 and the support bottom plate 1, a rod frame 94 fixedly connected to the rotating frame 92, two rotating rollers 95 rotatably connected to the rod frame 94, a bent rod 96 fixedly connected to one side of the rod frame 94 close to the support arm 2, a fixed rod 97 fixedly connected to the support bottom plate 1, an indicator lamp 98 fixedly connected to the upper portion of the fixed rod 97, and an electrified rod 99 fixedly connected to the side of the bent rod 96 away from the rod frame 94 and in contact with the lower portion of the indicator lamp 98.

[0036] Initially, the indicator lamp 98 is in a bright state. After the copper bar is horizontally placed on the positioning disc 41, the bottom of the copper bar is in contact with the two rotating rollers 95. When the axial direction of the copper bar is not coincident with the rotating axial direction of the alternating-current motor 3, the copper bar is in a deflected state with the two rotating rollers 95. The deflection of the two rotating rollers 95 drives the rod frame 94 and the rotating frame 92 to deflect together, the torsion spring 93 is twisted, and the deflection of the rod frame 94 by a certain angle drives the bent rod 96 and the electrified rod 99 to deflect together. When the electrified rod 99 and the bent rod 96 are deflected by a certain angle, the upper portion of the electrified rod 99 is out of contact with the lower end of the indicator lamp 98, so that the state of the indicator lamp 98 is changed, and the indicator lamp 98 changes from the bright state to the extinguished state. Then, the operator can adjust and correct the axial position of the copper bar, so that the indicator lamp 98 changes to the bright state. In this way, the operator can more conveniently adjust the position of the copper bar, so that the copper bar is not prone to uneven surface polishing due to inaccurate position.

[0037] The above has carried on the detailed introduction to the application, the principle and the implementation mode of the application have been described in this paper by applying specific examples, and the above embodiment description is only used to help understand the method and the core idea of the application; at the same time, for the general technical personnel in the art, according to the idea of the application, the specific implementation mode and the application range will be changed; in view of the above, the content of the specification should not be understood as the limitation of the application.
