[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A metal guide wire end grinding device includes a worktable 1, a Z-axis lead screw module 2 vertically mounted on the top of the worktable 1, an X-axis lead screw module 3 mounted on the side of the Z-axis lead screw module 2, a bearing plate 4 mounted on the side of the X-axis lead screw module 3, a rotary drive seat 5 mounted on the side of the bearing plate 4 away from the X-axis lead screw module 3, a rotary motor 6 mounted on the output end of the rotary drive seat 5, a guide tube 7 fixed to the output shaft of the rotary motor 6, and a guide wire to be processed passing through the guide tube 7, a rotary chuck 8 fixedly connected to one end of the guide tube 7, the rotary chuck 8 being used to clamp and fix the guide wire to be processed, a grinding disc drive platform 9 provided on the top of the worktable 1, and a grinding disc 10 horizontally mounted on the output shaft of the top of the grinding disc drive platform 9.

[0025] By adopting the above technical solution, the worktable 1 provides a stable bearing foundation, the Z-axis lead screw module 2 and the X-axis lead screw module 3 cooperate to realize the precise bidirectional movement of the bearing plate 4 in the X / Z axis, the rotary drive seat 5 can drive the rotary motor 6, the guide tube 7 and the rotating chuck 8 to rotate as a whole, the rotating chuck 8 can firmly hold the guide wire to be processed, the grinding disc drive table 9 drives the grinding disc 10 to rotate at high speed, and the coordinated action of each component not only meets the position adjustment requirements of guide wire grinding, but also ensures the synchronization of guide wire rotation and grinding, which greatly improves the accuracy and adaptability of guide wire grinding;

[0026] Among them, the rotating chuck 8 adopts a tapered clamping plate structure commonly used in the field of medical guidewire processing. In actual applications, this type of chuck has multiple tapered clamping plates inside that are adapted to medical metal guidewires. After the guidewire is inserted, the chuck's built-in adjustment mechanism (such as a manual tightening component or a small pneumatic drive) can drive the clamping plates to retract synchronously along the axis. The precise fit between the clamping plates and the guidewire surface achieves stable clamping, which can adapt to medical metal guidewires of different diameters and avoid excessive clamping force that could damage the guidewire surface. This rotating chuck structure is existing technology, so it will not be described in detail.

[0027] Both the Z-axis lead screw module 2 and the X-axis lead screw module 3 are slidably fitted with slides 11. The X-axis lead screw module 3 is fixed to the slide 11 of the Z-axis lead screw module 2 by detachable screws, and the bearing plate 4 is fixed to the slide 11 of the X-axis lead screw module 3 by detachable screws.

[0028] Using the above technical solutions, the slide table 11 of the Z-axis lead screw module 2 and the X-axis lead screw module 3 adopts a sliding fit design and a detachable screw connection method. This not only makes the installation, disassembly and position adjustment of the X-axis lead screw module 3 and the bearing plate 4 more convenient, but also ensures the stability of the slide table 11 during the sliding process, reduces module transmission error, further improves the positioning accuracy of the guide wire in the X / Z axis direction, and facilitates the later maintenance and component replacement of the equipment.

[0029] The rotary drive base 5 is mounted on the side of the support plate 4 by detachable screws. A rotary disk 12 is mounted on the output end of the rotary drive base 5 away from the support plate 4. An L-shaped bracket 13 is mounted on the side of the rotary disk 12 by detachable screws. The rotary motor 6 is fixedly mounted on the L-shaped bracket 13.

[0030] Using the above technical solution, the rotary drive seat 5 is fixed to the bearing plate 4 by detachable screws. The detachable connection structure between the rotary disk 12 and the L-shaped bracket 13 not only ensures the firmness of the connection between the rotary drive seat 5, the rotary disk 12, the L-shaped bracket 13 and the rotary motor 6, but also drives the entire motor mounting assembly to rotate stably through the power output of the rotary drive seat 5, accurately adjusts the relative angle between the guide wire and the grinding disk 10, and adapts to the grinding requirements of different guide wires.

[0031] Among them, the rotary drive seat 5 is existing technology. It usually achieves rotational power output through a built-in drive motor and transmission structure such as gears. The specific driving principle is not described in detail because the existing technology has been disclosed.

[0032] The L-shaped bracket 13 includes an integrally formed horizontal section and a vertical section. The horizontal section is fixed to the rotating disk 12 by detachable screws, and the rotating motor 6 is fixed to the inner side of the vertical section by detachable screws. A round hole is provided on the vertical section corresponding to the position of the output shaft of the rotating motor 6.

[0033] Using the above technical solutions, the L-shaped bracket 13 adopts an integrally formed horizontal and vertical section, which greatly improves its structural strength and load-bearing stability; the horizontal section is fixed to the rotating disk 12 by detachable screws to ensure the installation accuracy of the bracket; the round hole of the vertical section is precisely matched to the output shaft of the rotary motor 6, while providing a reasonable channel for the conduit 7 to pass through, avoiding interference between the conduit and the bracket, ensuring the installation compatibility between the motor and the conduit, and indirectly ensuring the stable operation of guide wire rotation grinding.

[0034] The rotary motor 6 is a hollow shaft motor, and the conduit 7 is coaxially inserted through the hollow shaft of the rotary motor 6, and the conduit 7 is fixedly connected to the hollow shaft.

[0035] By adopting the above technical solution, the rotary motor 6 is a hollow shaft motor, and the conduit 7 is coaxially inserted through the hollow shaft and fixedly connected. This design simplifies the installation structure of the conduit 7 and the rotary motor 6, and allows the power of the rotary motor 6 to be directly and without deviation transmitted to the conduit 7, driving the guide wire to rotate at high speed. At the same time, the coaxial design avoids eccentric oscillation when the guide wire rotates, effectively improving the surface smoothness and dimensional accuracy of the guide wire grinding.

[0036] The top of the grinding disc drive table 9 is fixed with a protective sleeve 14 with the opening facing upward. The output shaft of the grinding disc drive table 9 moves through the bottom end of the protective sleeve 14 and extends to the inside of the protective sleeve 14. The outer diameter of the grinding disc 10 is smaller than the inner diameter of the protective sleeve 14, and the grinding disc 10 is located inside the protective sleeve 14.

[0037] With the above technical solution, the protective cover 14 at the top of the grinding disc drive table 9 is designed with the opening facing upwards, and the grinding disc 10 is located inside the protective cover 14. This can effectively block the flying debris generated during the grinding process, protect the safety of the operators and the surrounding environment of the equipment, and also provide lateral protection for the grinding disc 10, preventing external debris from interfering with the operation of the grinding disc 10. At the same time, the design that the outer diameter of the grinding disc 10 is smaller than the inner diameter of the protective cover 14 does not affect the normal rotation of the grinding disc 10.

[0038] A washer 15 is fixedly sleeved on the outside of the output shaft of the grinding disc drive table 9. Fastening bolts 16 are installed through both sides of the bottom end of the washer 15. The grinding disc 10 is sleeved on the outside of the output shaft of the grinding disc drive table 9, and the bottom end of the grinding disc 10 is in contact with the top end of the washer 15. A reserved hole adapted to the fastening bolt 16 is opened on the grinding disc 10. After the fastening bolt 16 passes through the reserved hole, a nut is threadedly connected to it, and the grinding disc 10 is locked and fixed by the nut.

[0039] Using the above technical solution, the washer 15 provides a stable support surface for the grinding disc 10. The fastening bolt 16 passes through the reserved holes of the washer 15 and the grinding disc 10 and is locked by the nut. This fixing structure can firmly fix the grinding disc 10 on the output shaft of the grinding disc drive table 9, preventing the grinding disc 10 from slipping, shifting or vibrating when it is running at high speed, and ensuring the consistency of grinding accuracy. At the same time, the detachable bolt and nut structure makes the replacement operation of the grinding disc 10 more convenient and adapts to the grinding needs of guide wires of different materials and specifications.

[0040] Working principle:

[0041] After the guide wire to be processed is inserted into the guide tube 7 and clamped and fixed by the chuck 8, the Z-axis lead screw module 2 and the X-axis lead screw module 3 drive the bearing plate 4 and related components to move, determining the horizontal and vertical positions of the guide wire and the grinding disc 10. Then, the rotary drive seat 5 adjusts the overall tilt angle of the rotary motor 6 and the guide wire through the rotary disc 12, so that the area of ​​the guide wire to be processed and the grinding disc 10 form the required processing angle. After the equipment is started, the grinding disc drive table 9 drives the grinding disc 10 to rotate, and at the same time, the rotary motor 6 drives the guide wire to rotate to adjust its contact position with the grinding disc 10, so as to achieve uniform grinding. When processing the conical surface, the overall tilt angle of the guide wire remains unchanged. The rotary motor 6 continuously drives the guide wire to rotate, and in conjunction with the rotation of the grinding disc 10, the conical surface of the guide wire can be accurately processed. The protective sleeve 14 simultaneously blocks the flying of grinding debris.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
