[0002] Oxygen-free copper tube is a high-performance thermal conductive material. Because of its good high thermal conductivity, processing performance, corrosion resistance and high temperature stability, it plays a vital role in many high thermal conductivity applications. During the processing of oxygen-free copper tube, the inner wall of the low-tooth oxygen-free copper tube is provided with threads, and the outer surface of oxygen-free copper has high requirements for smoothness and needs to be polished and ground. A copper tube polishing machine is needed in this process.

[0003] The inventor found that when using a polishing machine to grind a steel pipe, the steel pipe itself is a smooth column. When the operator is polishing the steel pipe, it is very easy to shift on the processing table, causing the grinding position to shift and causing processing errors.

[0004] In order to solve the problem that when workers polish and grind steel pipes, it is very easy for them to shift on the processing table, resulting in the deviation of the grinding position and the occurrence of processing errors, the prior art solves the problem by using a multi-person collaboration method in which different workers are responsible for the work of limiting and grinding respectively. The present invention adopts another solution. Summary of the invention

The threaded rod 72 will drive the rectangular plate 73 to move synchronously during the extension and retraction process, and the rectangular plate 73 will drive the half ring 75 connected to the round rod 74 to move synchronously. When the two half rings 75 completely clamp the oxygen-free copper tube body 12 placed on the operating plate 11 under the action of the threaded rod 72, the two half rings 75 can effectively limit the oxygen-free copper tube body 12, which is beneficial to prevent the oxygen-free copper tube body 12 on the processing table from shifting, thereby preventing the grinding position from shifting and causing processing errors, thereby improving the overall practicality.

[0041] Reference Figure 3As shown in FIG. 7 , this embodiment discloses that one end of the threaded rod 72 is fixedly connected to a bearing 76, and the outer surface of the bearing 76 is fixedly connected to the inner wall of the rectangular plate 73. By setting the bearing 76, the inner ring of the bearing 76 is fixed to the outer surface of one end of the threaded rod 72, and the outer ring of the bearing 76 is fixed to the inner wall of the rectangular plate 73. When the threaded rod 72 rotates, the inner ring of the bearing 76 will drive the inner ring of the bearing 76 to rotate, and the inner ring of the bearing 76 will rotate on the inner wall of the outer ring, thereby effectively reducing the friction between the threaded rod 72 and the inner wall of the rectangular plate 73 during the rotation of the threaded rod 72.

By providing the operating block 77, rotating the operating block 77 can drive the threaded rod 72 to rotate. At the same time, the outer surface of the operating block 77 is provided with bumps, which can effectively increase the roughness of the outer surface of the operating block 77, and thus can reduce the friction of the outer surface of the operating block 77, which has an anti-slip effect when the operating block 77 is rotated, thereby facilitating the rotation of the threaded rod 72 through the operating block 77.

[0042] Reference Figure 3-Figure 5 As shown, the present embodiment discloses that a slider 78 is fixedly connected to the bottom of the rectangular plate 73, and a slide groove 79 is provided on the top of the box body 1. The outer surfaces of the two sliders 78 are slidably connected to the inner wall of the slide groove 79. By providing the sliders 78 and the slide groove 79, when the rectangular plate 73 moves on the top of the box body 1 under the action of the threaded rod 72, the rectangular plate 73 will drive the slider 78 to slide synchronously on the inner wall of the slide groove 79, thereby limiting the rectangular plate 73 and preventing the threaded rod 72 from rotating. The rectangular plate 73 is driven to rotate synchronously, so that the rectangular plate 73 is more stable during the movement; the inner wall of the semi-ring 75 is fixedly connected with a rubber block 710, and a plurality of grooves are evenly arranged on one side of the rubber block 710. By setting the rubber block 710, the outer surface of the rubber block 710 is provided with grooves, thereby effectively increasing the friction force on the inner side of the semi-ring 75, and thus when the semi-ring 75 clamps the oxygen-free copper tube body 12, it has an anti-slip effect, preventing the oxygen-free copper tube from easily escaping from the clamping of the two semi-rings 75.

[0043] Reference Figure 6 and Figure 7 As shown, this embodiment discloses that the easy-to-disassemble device 9 includes a circular hole block, a middle portion of one side of the circular hole block is fixedly connected to one end of the round rod 74, a threaded pin 92 is symmetrically inserted into the inner wall of the circular hole block, one end of the threaded pin 92 is fixedly connected to one side of the rectangular plate 73, and one side of the circular hole block abuts against one side of the rectangular plate 73. By providing the circular hole block and the threaded pin 92, the half ring 75 can be disassembled at the same time, thereby facilitating the maintenance and replacement of the half ring 75.

[0044] Reference Figure 6 and Figure 7As shown, this embodiment discloses that a screw hole block 93 is provided on the outer surface of the threaded pin 92, and the outer surface of the threaded pin 92 is threadedly inserted into the inner wall of the screw hole block 93, and one side of the screw hole block 93 abuts against one side of the rectangular plate 73. By providing the screw hole block 93, the screw hole block 93 is sleeved on the outer surface of one end of the threaded pin 92, and the screw hole block 93 is rotated so that one side of the screw hole block 93 abuts against one side of the circular hole plate 91, then the screw hole block 93 can fix the circular hole block and the threaded pin 92 to prevent the circular hole block from shifting on the outer surface of the threaded pin 92.

[0045] Reference Fig. 9 and Fig.10 As shown, this embodiment discloses that the height adjustment device 8 includes two rectangular rods 81, one end of the two rectangular rods 81 is symmetrically fixedly connected to the bottom of the operating panel 11, the outer surface of the rectangular rod 81 is slidably connected with a sleeve 82, and one end of the sleeve 82 is fixedly connected to the top of the box body 1. By arranging the rectangular rod 81 and the sleeve 82, the rectangular rod 81 can slide on the inner wall of the sleeve 82, thereby facilitating the adjustment of the height of the operating table according to actual needs, and making it more convenient to grind the oxygen-free steel pipe body.

[0046] Reference Fig. 9 and Fig.10 As shown, the present embodiment discloses that a threaded telescopic rod 83 is fixedly connected to the bottom of the operating panel 11, and a threaded barrel 84 is threadedly connected to the outer surface of the threaded telescopic rod 83, and one end of the threaded barrel 84 is rotatably connected to the top of the box body 1. By setting the threaded barrel 84 and the threaded telescopic rod 83, the threaded barrel 84 is rotated, and the threaded barrel 84 will drive the threaded telescopic rod 83 to extend and retract on the inner wall of the threaded barrel 84. During the extension and retraction process, the threaded telescopic rod 83 will drive the operating panel 11 to slide synchronously in the vertical direction. At the same time, when the threaded barrel 84 stops rotating, the threaded barrel 84 can fix the threaded telescopic rod 83, thereby facilitating the height adjustment of the operating panel 11 through the threaded barrel 84; a rubber sleeve 85 is fixedly connected to the outer surface of the threaded barrel 84, and grooves are evenly opened on the outer surface of the rubber sleeve 85. By setting the rubber sleeve 85 with grooves, the friction force of the outer surface of the threaded barrel 84 can be increased, thereby having an anti-slip effect when the threaded barrel 84 is rotated.

[0047] The working principle is as follows: when it is necessary to install the half ring 75, the threaded pin 92 is inserted into the inner wall of the circular hole block so that one side of the circular hole block abuts against one side of the rectangular plate 73, and the circular hole block can limit the threaded pin 92, thereby connecting the round rod 74 and the rectangular plate 73, that is, connecting the half ring 75 and the rectangular plate 73, and then the screw hole block 93 is sleeved on the outer surface of one end of the threaded pin 92, and the screw hole block 93 is rotated so that one side of the screw hole block 93 is in contact with one side of the circular hole plate 91, then the screw hole block 93 can fix the circular hole block and the threaded pin 92 to prevent the circular hole block from shifting on the outer surface of the threaded pin 92, and the installation is completed. At the same time, the half ring 75 can also be disassembled, thereby facilitating the maintenance and replacement of the half ring 75; when it is necessary to repair the operating panel 11 When adjusting the height of the operating table 11, the rubber sleeve 85 is held to drive the threaded cylinder 84 to rotate, and the threaded cylinder 84 will drive the threaded telescopic rod 83 to extend and retract on the inner wall of the threaded cylinder 84. The threaded telescopic rod 83 will drive the operating panel 11 to slide synchronously in the vertical direction during the extension and retraction process. At the same time, when the threaded cylinder 84 stops rotating, the threaded cylinder 84 can fix the threaded telescopic rod 83, thereby facilitating the height adjustment of the operating panel 11 through the threaded cylinder 84, thereby facilitating the height adjustment of the operating table according to actual needs, and making it easier to grind the oxygen-free steel pipe body. At the same time, the rubber sleeve 85 with grooves can increase the friction force of the outer surface of the threaded cylinder 84, thereby having an anti-slip effect when the threaded cylinder 84 is rotated. When it is necessary to place the operating panel 11 on the operating panel 11, The operation block 77 is rotated to limit the oxygen-free steel pipe body. Since the operation block 77 can drive the threaded rod 72 to rotate, and the outer surface of the operation block 77 is provided with a protrusion, the roughness of the outer surface of the operation block 77 can be effectively increased, thereby the friction of the outer surface of the operation block 77 can be prevented from slipping when the operation block 77 is rotated, thereby facilitating the rotation of the threaded rod 72 by the operation block 77. The threaded rod 72 will drive the inner ring of the bearing 76 to rotate when rotating, and the inner ring of the bearing 76 will rotate on the inner wall of the outer ring, thereby effectively reducing the friction between the threaded rod 72 and the inner wall of the rectangular plate 73 during the rotation of the threaded rod 72, thereby making it more labor-saving when rotating the threaded rod 72, and the threaded rod 72 will extend on the inner wall of the auxiliary plate 71 The threaded rod 72 will drive the rectangular plate 73 to move synchronously during the extension and retraction process, and the rectangular plate 73 will drive the semi-ring 75 connected to the round rod 74 to move synchronously. When the rubber blocks 710 on the inner sides of the two semi-rings 75 completely clamp the oxygen-free copper tube body 12 placed on the operating plate 11 under the action of the threaded rod 72, the two semi-rings 75 can effectively limit the oxygen-free copper tube body 12. At the same time, the rubber blocks 710 with grooves can effectively increase the friction force on the inner side of the semi-rings 75, and then when the semi-rings 75 clamp the oxygen-free copper tube body 12, it has an anti-slip effect, which is beneficial to prevent the oxygen-free copper tube body 12 on the processing table from shifting, and then prevent the grinding position from shifting, resulting in processing errors, thereby improving the overall practicality.
