Description

Technical Field

[0001] This utility model belongs to the field of titanium tube processing technology, and in particular relates to a polishing device for titanium tube processing. Background Technology

[0002] Titanium tubes are widely used in chemical, aerospace, and medical fields due to their excellent corrosion resistance, high strength, and biocompatibility. Polishing, as a key process in titanium tube manufacturing, directly affects its surface finish, fatigue resistance, and subsequent performance.

[0003] Currently, traditional polishing equipment mostly employs a single inner or outer wall grinding method, requiring step-by-step operation, resulting in low efficiency and difficulty in ensuring the consistency of inner and outer surfaces. Furthermore, existing equipment has poor adaptability to titanium tube diameters and wall thicknesses, with cumbersome adjustment processes that can easily lead to uneven polishing or excessive wear. Therefore, we provide a polishing device for titanium tube processing to solve the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5This utility model is a polishing device for titanium tube processing, including a housing 1, a machine box 2 fixedly connected to the inner cavity of the housing 1, and a clamping mechanism 3 provided on the top of the machine box 2; a drive assembly is provided in the inner cavity of the machine box 2, the drive assembly includes a drive motor 4 fixedly connected to the right side of the machine box 2, a threaded rod 5 fixedly connected to the output shaft of the drive motor 4, a threaded sleeve 6 threadedly connected to the surface of the threaded rod 5, a limiting rod 7 fixedly connected to the surface of the threaded sleeve 6, and a slider 8 fixedly connected to the other end of the limiting rod 7; an adaptive assembly is provided on the top of the slider 8, the adaptive assembly includes a first hydraulic cylinder 9 fixedly connected to the top of the slider 8, a fixed frame 10 fixedly connected to the telescopic end of the first hydraulic cylinder 9, a servo motor 11 fixedly connected to one side of the fixed frame 10 through a mounting block, an inner polishing roller 12 fixedly connected to the surface of the output shaft of the servo motor 11, a support block 13 slidably connected to the inner side of the fixed frame 10, and an outer polishing roller 14 movably connected to the inner wall of the support block 13 through a bearing seat.

[0027] Further details: The housing 1 has a rectangular sealed structure, with the housing 2 welded to the bottom of its inner cavity. The clamping mechanism 3 includes a three-jaw chuck and a rotating module (existing technology), which facilitates clamping and fixing the titanium tube and driving its rotation. The other end of the threaded rod 5 is movably connected to the inner cavity of the housing 2 through a bearing seat. There are three first hydraulic cylinders 9 to ensure that the fixed frame 10 moves up and down more stably. The support block 13 has T-shaped blocks fixedly connected to both the front and back. The support block 13 slides in the inner cavity of the fixed frame 10 through the T-shaped blocks, thereby controlling the distance between the outer grinding roller 14 and the inner grinding roller 12, and adaptively adjusting according to the wall thickness of the titanium tube.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, one end of the limiting rod 7 extends through to the outside of the housing 2. The top of the housing 2 is provided with a limiting groove 15 that matches the limiting rod 7. A first bevel gear 16 is fixedly connected to the surface of the inner grinding roller 12. A second bevel gear 17 meshes with the surface of the first bevel gear 16. A third bevel gear 18 is fixedly connected to the surface of the outer grinding roller 14. A fourth bevel gear 19 meshes with the surface of the third bevel gear 18. A fixing rod 20 is fixedly connected to the shaft of the second bevel gear 17. A fixing cylinder 21 is fixedly connected to the shaft of the fourth bevel gear 19. The fixing cylinder 21 is sleeved on the surface of the fixing rod 20. A locking block 22 is fixedly connected to the surface of the fixing rod 20. A locking groove 23 that matches the locking block 22 is provided in the inner cavity of the fixing cylinder 21. A second hydraulic cylinder 24 is fixedly connected to the inner cavity of the fixing frame 10. The telescopic end of the second hydraulic cylinder 24 is fixedly connected to the bottom of the support block 13. A control panel 25 is provided on the left side of the front of the housing 1. A protective door 26 is slidably connected to the right side of the front of the housing 1.

[0030] Further details: When the limiting rod 7 passes through the limiting groove 15 at the top of the housing 2, it forms a clearance fit to achieve precise guidance, ensuring that the threaded sleeve 6 only moves axially under the drive of the threaded rod 5, eliminating radial swing error. The first bevel gear 16 and the second bevel gear 17 form a 90-degree orthogonal transmission pair. The fixed rod 20 is fixed to the side wall of the fixed frame 10 through a deep groove ball bearing, transmitting the torque of the servo motor 11 to the outer grinding roller 14. The third bevel gear 18 and the fourth bevel gear 19 are the same. The end of the fixed cylinder 21 is connected to the shaft end of the outer grinding roller 14 to form an adjustable transmission structure. The locking block 22 has a cross-shaped key structure, which forms a torque transmission interface with the cross-shaped locking groove 23 in the inner cavity of the fixed cylinder 21, allowing the fixed rod 20 to slide axially in the fixed cylinder 21, allowing free axial extension and contraction while ensuring radial fit accuracy, realizing continuous power transmission of the transmission shaft during the extension and contraction process. The second hydraulic cylinder 24 pushes the outer grinding roller 14 to perform vertical precision positioning within the range, and adaptively adjusts in accordance with the titanium tube wall thickness.

[0031] The working principle of this utility model is as follows: During operation, the titanium tube is horizontally inserted into the box 1, clamped by the three-jaw chuck of the clamping mechanism 3 and driven to rotate. The servo motor 11 is started, which drives the inner grinding roller 12 to rotate at high speed. The inner grinding roller 12 transmits power to the fixed rod 20 through the meshing of the first bevel gear 16 and the second bevel gear 17. The fixed rod 20 cooperates with the slot 23 of the fixed cylinder 21 through the locking block 22, driving the fourth bevel gear 19 and the third bevel gear 18, so that the outer grinding roller 14 rotates synchronously in opposite directions, forming bidirectional grinding inside and outside.

[0032] Subsequently, the first hydraulic cylinder 9 pushes the fixed frame 10 upward, so that the inner grinding roller 12 fits against the inner wall of the titanium tube; the second hydraulic cylinder 24 drives the support block 13 to press down, adjusting the outer grinding roller 14 to the preset pressure on the outer wall of the titanium tube. After the drive motor 4 starts, the output shaft of the drive motor 4 drives the threaded rod 5 to rotate. The threaded rod 5 drives the threaded sleeve 6 and the limit rod 7 to move axially, so that the slider 8 assembly drives the grinding unit to feed from one end of the titanium tube to the other end at a uniform speed, completing the full-section polishing. During the process, the clamping block 22 slides in the clamping groove 23 of the fixed cylinder 21 to ensure stable power transmission during axial movement. The design of the bevel gear set makes the inner and outer rollers rotate at the same speed, avoiding surface texture differences caused by speed differences.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
