However, the present application can be practiced according to other embodiments that do not require the specific details described in this description. Therefore, the present application is not limited to the embodiments described herein and can be practiced according to other embodiments that do not require the specific details described in this description.

[0025] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0026] Embodiments

[0027] Reference Figures 1-6 For the embodiment of the present application, the embodiment provides a groove polishing device for medical accessory processing, comprising,

[0028] The polishing machine body 100 comprises a workbench 101, a polishing head 102 adaptedly installed on the outer surface of the workbench 101, and a workpiece clamp 103 arranged on the outer surface of the workbench 101 and cooperating with the polishing head 102;

[0029] It should be noted that the workbench 101 is used to provide an installation platform for components such as the polishing head 102 and the workpiece clamp 103, to ensure that the polishing operation is stable, the polishing head 102 is used to directly polish the groove of the medical accessory, and the high-speed rotating mode is used to remove the surface material of the accessory, so that the required smoothness is achieved, the workpiece clamp 103 is used to firmly fix the medical accessory, to prevent displacement of the accessory during polishing, and to ensure that the polishing head 102 can accurately process the groove.

[0030] The protection mechanism 200 comprises a cleaning assembly 201 arranged on the surface of the workbench 101 for protecting the operator and having a self-cleaning function, and a locking assembly 202 for preventing the position of the cleaning assembly 201 from deviating.

[0031] Specifically, the cleaning assembly 201 comprises a first support block 201a fixedly connected to the outer surface of the workbench 101, a first connecting column 201b fixedly installed on the inner surface of the first support block 201a through a bearing, a splash plate 201c fixedly connected to the outer end surface of the first support block 201a, and a sun gear 201d fixedly sleeved on the outer surface of the splash plate 201c.

[0032] It should be noted that the first support block 201a is used to support the first connecting column 201b. The first connecting column 201b is the basic support component for the rotation of the splash guard 201c, allowing the splash guard 201c to rotate flexibly around it. The splash guard 201c is used to block debris, abrasive and other splashes generated during the polishing process, thereby protecting the safety of the operator. The stellar gear 201d can rotate synchronously when the splash guard 201c rotates.

[0033] Furthermore, the cleaning assembly 201 also includes a planetary gear 201e meshing with the outer surface of the sun gear 201d, a gear disk 201f fixedly mounted on the outer surface of the worktable 101 and used in conjunction with the planetary gear 201e, a reciprocating roller 201g fixedly connected to the inner surface of the planetary gear 201e, a movable sleeve 201h slidably sleeved on the outer surface of the reciprocating roller 201g, and a scraper 201i fixedly connected to the outer surface of the movable sleeve 201h and used in conjunction with the splash guard 201c.

[0034] It should also be noted that when the planetary gear 201e rotates, it can drive the sun gear 201d to roll along the inner surface of the toothed disk 201f. At the same time, the sun gear 201d drives the reciprocating roller 201g to roll synchronously. The rotation of the reciprocating roller 201g drives the movable sleeve 201h and the scraper 201i to move back and forth linearly along the outer surface of the splash guard 201c, so as to achieve the effect of cleaning the surface of the splash guard 201c.

[0035] Preferably, the cleaning assembly 201 further includes a limiting rod 201j fixedly connected to the outer surface of the splash guard 201c, a limiting groove 201k formed on the outer surface of the splash guard 201c and used in conjunction with the limiting rod 201j, a fixing block 201l fixedly installed on the outer surface of the splash guard 201c and used in conjunction with the reciprocating roller 201g, a second connecting post 201m fixedly connected to the side of the splash guard 201c away from the first connecting post 201b, and a second support block 201n fixedly installed on the surface of the workbench 101 away from the first support block 201a and used in conjunction with the second connecting post 201m.

[0036] The limiting rod 201j and the limiting groove 201k work together to limit the movement trajectory of the scraper 201i during reciprocating movement, ensuring that the splash guard 201c can be effectively cleaned. The fixing block 201l provides support and positioning for the reciprocating roller 201g, ensuring its rotational stability. The second connecting column 201m and the second support block 201n work together to assist in supporting the splash guard 201c and ensuring its rotational stability.

[0037] It should be noted that the outer surface of the planetary gear 201e meshes with the inner surface of the gear disk 201f, the outer surface of the limiting rod 201j slides in contact with the inner wall of the limiting groove 201k, the outer surface of the reciprocating roller 201g rotates in contact with the inner surface of the fixed block 201l, and a rotating bearing sleeve is installed at the connection between the second connecting column 201m and the second support block 201n.

[0038] Furthermore, the locking assembly 202 includes a turntable 202a fixedly sleeved on the outer end face of the second connecting post 201m, positioning holes 202b arranged in a circumferential array on the outer surface of the turntable 202a, a fixed sleeve 202c fixedly connected to the outside of the worktable 101, a positioning rod 202d movably connected to the inner surface of the fixed sleeve 202c and used in conjunction with the positioning hole 202b, a slider 202e fixedly sleeved on the outer surface of the positioning rod 202d, and a spring 202f sleeved on the outer surface of the positioning rod 202d and used in conjunction with the slider 202e.

[0039] It should be explained that the turntable 202a can rotate synchronously with the positioning hole 202b driven by the second connecting column 201m. Through the cooperation of the positioning hole 202b and the positioning rod 202d, the turntable 202a and the second connecting column 201m can be positioned, thereby keeping the splash guard 201c at a suitable angle. The fixed sleeve 202c is used to provide the positioning rod 202d with a space for movement, ensuring that it can move axially. The positioning rod 202d can be inserted into or pulled out of the positioning hole 202b on the turntable 202a, thereby realizing the locking and unlocking function of the splash guard 201c. The slider 202e is used to transmit the linear power of the positioning rod 202d when it moves to the spring 202f, so that the spring 202f can automatically insert the positioning rod 202d into the positioning hole 202b through the reaction force, ensuring the stability of the position of the splash guard 201c.

[0040] Specifically, the outer surface of the slider 202e slides in contact with the inner wall of the fixed sleeve 202c, and the outer end face of the spring 202f is fixedly connected to the inner wall of the fixed sleeve 202c.

[0041] In use, place the medical accessory on the workpiece clamp 103 and secure it firmly to prevent displacement during polishing. Manually pull out the positioning rod 202d to overcome the elastic force of the spring 202f. At this time, the turntable 202a and the second connecting column 201m are unlocked, and the splash guard 201c is adjusted to a suitable protective position. Release the positioning rod 202d, and under the reaction force of the spring 202f, insert the positioning rod into the corresponding positioning hole 202b on the turntable 202a to lock the position of the splash guard 201c.

[0042] The grinding head 102 is activated, and its high-speed rotation polishes the groove of the medical accessory fixed on the workpiece fixture 103, removing surface material and achieving the required smoothness. During this process, the splash guard 201c prevents debris and abrasive particles from flying off, protecting the operator's safety.

[0043] After polishing: Manually pull out the positioning rod 202d again to unlock the splash guard 201c, and manually rotate the splash guard 201c. The rotation of the splash guard 201c drives the sun gear 201d to rotate synchronously. The sun gear 201d drives the planet gear 201e to rotate around the sun gear 201d, and at the same time, it also drives the reciprocating roller 201g to rotate synchronously. Through the cooperation of the limiting rod 201j and the limiting groove 201k, the movable sleeve 201h and the scraper 201i are limited, so that the movable sleeve 201h and the scraper 201i move back and forth in a straight line along the surface of the splash guard 201c through the rotation of the reciprocating roller 201g, and clean its surface to remove surface stains.

[0044] After cleaning: Loosen the positioning rod 202d so that it can be inserted into the positioning hole 202b on the turntable 202a under the elastic force of the spring 202f, and re-lock the position of the splash guard 201c.

[0045] In summary, the cleaning component 201 automatically removes impurities from the surface of the splash guard 201c during the opening process after polishing. This prevents operators from coming into contact with harmful substances such as chemical polishing agents and metal dust when manually cleaning the splash guard 201c, thus protecting the health of operators and preventing scratches on the surface of the splash guard 201c caused by improper use of manual cleaning tools or excessive force. This ensures that the protective performance of the splash guard 201c is not affected while extending its service life. At the same time, the locking component 202 allows for flexible adjustment and precise locking of the position of the splash guard 201c, ensuring its stable protective function during polishing operations.
