[0025] See also Figure 1-5 The utility model provides an embodiment of a copper tube surface rotary polishing device, comprising a machine base 1, a polishing table 2 is fixedly mounted on the upper surface of the machine base 1, a horizontally arranged guide groove 3 is opened at the center position of the upper surface of the polishing table 2, a first-level screw rod 4 is mounted in the guide groove 3 through a bearing, the first-level screw rod 4 is a forward and reverse screw rod, the bottom end of the first-level screw rod 4 is fixedly connected to the output shaft of the first-level motor 5, the first-level motor 5 is fixedly mounted on the side wall of the polishing table 2, and the forward and reverse threads on both sides of the first-level screw rod 4 are threadedly connected to the first-level thread seat 6;

[0026] This structural design allows the primary motor 5 to rotate. Since the primary screw 4 is a forward and reverse threaded screw, when the primary motor 5 rotates, the two primary threaded seats 6 threadedly connected thereto move relative to each other, thereby driving the structural assembly thereon to move relative to each other through the primary threaded seats 6.

[0027] A secondary guide rail 7 is fixedly mounted on the primary threaded seat 6. The secondary guide rail 7 is perpendicular to the guide groove 3. A secondary screw rod 8 is mounted in the secondary guide rail 7 through a bearing. A secondary threaded seat 9 is threadedly connected to the secondary screw rod 8. One end of the secondary screw rod 8 is fixedly connected to the output shaft of the secondary motor 10. In order to better perform comprehensive servo control on the motor, both the primary motor 5 and the secondary motor 10 are servo motors.

[0028] An upper fixing seat 11 is fixedly mounted on the upper surface of the secondary threaded seat 9, and a mounting inclined plate 12 is fixedly mounted on the upper surface of the upper fixing seat 11. A polishing motor 13 is fixedly mounted on the inclined surface of the mounting inclined plate 12 by bolts, and a polishing disc 14 is fixedly mounted on the output shaft of the polishing motor 13 through the mounting inclined plate 12;

[0029] According to the above structure, the polishing motor 13 can drive the polishing disc 14 to rotate at high speed through its output shaft, thereby ensuring the polishing of the outer surface of the copper tube through the high-speed rotation of the polishing disc 14;

[0030] At the same time, the above-mentioned structure of the present invention is provided with a secondary motor 10, which can drive the secondary screw rod 8 to rotate through the output shaft through the secondary motor 10. When the secondary screw rod 8 is rotating, the secondary threaded seat 9 threadedly connected thereto will drive the polishing motor 13 and the polishing disk 14 on the upper fixed seat 11 to perform forward and backward displacement work, thereby effectively moving the polishing disk 14, thereby completing the forward and backward displacement polishing process of the outer surface of the copper tube, increasing the polishing mobility, improving the polishing coverage area, and having good practicality.

[0031] In this embodiment, in order to clamp and rotate the copper tube, please refer to the attached manual for details. Figure 5 As shown, a cylinder seat 15 is fixedly mounted on the middle position of the polishing table 2 and on both sides of the guide groove 3 by fixing bolts, and a vertical mounting plate 16 is fixedly mounted on the cylinder seat 15;

[0032] Furthermore, a driving cylinder 17 is fixedly mounted on the outer wall of one side of the mounting plate 16 by fixing bolts. A driving rod is telescopically movable at the output end of the driving cylinder 17. A rotating motor 18 is fixedly mounted on the top end of the driving rod. A clamping disc 19 is fixedly mounted on the output shaft of the rotating motor 18.

[0033] In this structural design, the driving cylinder 17 is provided to drive the driving rod at the top to move. When the copper tube to be polished is placed between the two clamping plates 19, the driving cylinder 17 drives the rod body to extend, thereby driving the clamping plates 19 to move by the extension of the driving rod. The displacement of the clamping plates 19 can clamp and fix the ends of the copper tube on both sides, facilitating the subsequent polishing process.

[0034] A rotating motor 18 is provided on the outer surface of the clamping disc 19 , so that the rotating motor 18 can drive the copper tube on the clamping disc 19 to rotate slowly, thereby achieving the effect of fully polishing the outer surface in actual use.

[0035] In this embodiment, in order to facilitate the programming or function setting of the polishing device, a bracket 20 is fixedly installed on one side of the outer surface of the machine base 1, and a control panel 21 is fixedly installed on the top upper surface of the bracket 20. The control panel 21 consists of a shell, a display screen and physical buttons, and is used for programming or function setting operations of the utility model.

[0036] Working principle: When it is necessary to perform rotary polishing on the outer surface of a small copper tube, the staff can hold the copper tube and place it between the clamping plates 19 of the two sets of cylinder-driven clamping structures. At this time, the driving cylinder 17 can work. When the driving cylinder 17 works, it drives the top end to extend. When the two sets of rods extend relative to each other, the clamping plates 19 can complete the fixed clamping work of the two ends of the copper tube. It has a certain cylinder-driven clamping effect, which is convenient for subsequent polishing processing. The copper tube can be loosened after the clamping plates 19 are clamped.

[0037] At this time, the two rotating motors 18 are started, and the rotating motors 18 can drive the copper tube between the two clamping plates 19 to rotate slowly, thereby assisting in the subsequent comprehensive polishing of the outer surface of the copper tube;

[0038] Afterwards, the primary motor 5 is rotated, and when the primary motor 5 rotates, the primary screw rod 4 is driven to rotate. Since the primary screw rod 4 is a forward and reverse threaded screw rod, when the primary motor 5 rotates, the two primary threaded seats 6 threadedly connected thereto will move relative to each other, that is, move away from or closer to each other (this effect depends on the forward and reverse rotation of the primary motor 5), thereby driving the structural assembly thereon to move as a whole through the primary threaded seats 6;

[0039] When the two primary threaded seats 6 approach each other, the polishing discs 14 move synchronously relative to each other, so that the polishing discs 14 can contact the outer surface of the copper tube. At this time, the polishing motor 13 can drive the polishing discs 14 to rotate at high speed through its output shaft, so that the outer surface of the copper tube is polished by the high-speed rotation of the polishing discs 14 and the rotation of the copper tube.

[0040] At the same time, the utility model is provided with a secondary motor 10, which can drive the secondary screw 8 to rotate through the output shaft. When the secondary screw 8 rotates, the secondary threaded seat 9 threadedly connected thereto drives the polishing motor 13 and the polishing disc 14 on the upper fixed seat 11 to perform forward and backward displacement work, thereby effectively moving the polishing disc 14. In actual use, the forward and backward displacement polishing process of the outer surface of the copper tube can be completed, the mobility of the polishing position is increased, the overall coverage area of ​​the polishing work is improved, and it has good practicality.

[0041] After the polishing of a single copper tube is completed, the various structures are reset by relative movement. At this time, the staff removes the polished copper tube, places a new copper tube for clamping, and performs polishing processing in the above manner, thereby completing the cyclic polishing processing of the utility model.

[0042] In summary, the polishing device of the present invention can perform positioning and clamping work on both ends of the copper tube by means of oil cylinder drive, which is convenient for subsequent polishing processing, and the telescopic clamping structure can be applied to positioning and clamping of copper tubes of different lengths, which greatly improves the length application range of the present invention, reduces the limitation of use, and can perform positioning and clamping processing on copper tubes of different lengths;

[0043] At the same time, the positioning and clamping structure is provided with a rotating motor. The rotating motor 18 can drive the copper tube between the two clamping disks 19 to rotate slowly, thereby assisting in the subsequent comprehensive polishing of the outer surface of the copper tube, avoiding the occurrence of polishing dead corners, and having the use characteristics of comprehensive polishing of the outer surface;

[0044] Finally, the polishing disc provided can be used to grind and polish the outer surface of the copper tube, and the polishing disc can be displaced under the drive of the secondary motor and the secondary screw rod, so that the displacement of the polishing disc can effectively increase the overall coverage area of ​​the polishing, effectively complete the comprehensive polishing process from the tail end to the top end of the copper tube, increase the mobility of the polishing position, and improve the overall polishing quality of the polishing work. It has good practicality, and the utility model can effectively improve the outer surface polishing efficiency of small copper tubes by replacing manual labor with machinery to perform rotational polishing of the outer surface of the copper tube, reduce labor cost investment, thereby reducing the processing cost of the copper tube and improving the economic benefits of the enterprise, and the polishing force is controllable, effectively avoiding the uneven phenomenon of manual polishing, improving the product production quality of the copper tube, and is suitable for promotion and use.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
