DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail. The embodiments described below are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In order to solve the problem that conventional tooling in the prior art cannot adapt to medical drill bits with large heads and tails and small middles, the utility model provides a grinding support tooling for medical drill bits, see Figure 2-Figure 8 As shown, the medical drill 1 in the medical drill grinding support tooling includes an end head 11 and a rod body 12. The diameter of the end head 11 is larger than the diameter of the rod body 12. The medical drill grinding support tooling includes a base 3 and a positioning block 2 for placing the medical drill bit 1. The positioning block 2 is detachably fixed to the base 3, wherein an upper stopper 21 is provided at one end of the positioning block 2, and an avoidance groove 22 for accommodating the end head 11 is provided below the upper stopper 21. The other end of the positioning block 2 is provided with a support seat 23 for supporting the rod body 12; at least one axial positioning structure is provided on the positioning block 2 to realize axial positioning of the medical drill bit 1.

[0029] The medical drill grinding support fixture of the present invention has a wide range of applicability. It is not only suitable for ordinary medical drill bits 1 with a diameter of the end 11 and the rod body 12 of the medical drill bit 1, but can also effectively handle the grinding processing of medical drill bits with large head and tail diameters and small middle diameters. Moreover, the grinding support fixture passes the end 11 of the medical drill bit 1 through the avoidance groove 22, and under the action of the axial positioning structure, the rod body 12 of the medical drill bit 1 is supported parallel and firmly on the support seat 23, thereby ensuring the accuracy and stability during the processing. In addition, the entire clamping process is very simple, and fast clamping can be achieved, which greatly improves the clamping efficiency, thereby optimizing the entire processing process and improving the processing quality.

[0030] Specifically, to ensure the stability and reliability of the medical drill during the grinding process, the preferred axial positioning structure of the present invention is a support groove 231 provided on the support seat 23 for accommodating the rod body 12 .

[0031] Furthermore, in order to provide more precise support, the present invention preferably configures the support groove 231 to be an arc-shaped support groove that matches the shape of the rod body 12 .

[0032] The preferred axial positioning structure of the present invention is an arc-shaped avoidance groove 24 opened above the avoidance groove 22 and connected thereto; and the arc-shaped avoidance groove 24 matches the shape of the rod body 12; it provides better adaptability and stability, ensuring the precise positioning of the medical drill bit 1 during the grinding process.

[0033] Furthermore, the utility model preferably has the above-mentioned two axial positioning structures at the same time, one axial positioning structure is a support groove 231 opened on the support seat 23, and the other axial positioning structure is an arc-shaped avoidance groove 24 opened above the avoidance groove 22 and connected thereto; wherein, the support groove 231 is designed as a lower arc shape, and the arc-shaped avoidance groove 24 is designed as an upper arc shape; during the grinding process, the support groove 231 mainly assumes the supporting function, and together with the arc-shaped avoidance groove 24 constitutes a stable support system, which effectively prevents the movement of parts during the processing process and ensures the accuracy and stability of the processing.

[0034] In order to facilitate processing while providing enough space to allow the end 11 of the medical drill bit 1 to pass through, thereby enhancing the applicability and flexibility of the tooling, the avoidance groove 22 of the present invention is preferably a square groove.

[0035] Since the diameter of the end head 11 of the medical drill bit 1 of the present invention is 6.35 mm, the diameter of the end head 11 at the other end is 7 mm, and the diameter of the middle rod body 12 is 5.08 mm, the size of the avoidance groove 22 of the present invention is preferably 10 mm long, 16 mm wide, and 12 mm deep, which ensures the effectiveness of the avoidance groove 22 and allows the rod body 12 to have enough space to pass through the avoidance groove 22 and lean obliquely on the support seat 23; the size of the avoidance groove 22 can be set according to the specific size of the medical drill bit 1 and the height of the upper stop block 21 and the support seat 23.

[0036] In order to improve the flexibility of operation, the utility model preferably provides a groove 25 between the upper stop block 21 and the support seat 23; the upper plane of the groove 25 is lower than the upper plane of the support seat 23, which helps to provide an additional positioning and fixing space for the medical drill bit 1 after the medical drill bit 1 passes through the avoidance groove 22; further, the utility model preferably has a width of the groove 25 of 20 mm. This size not only ensures sufficient space to accommodate the medical drill bit 1, but also ensures the compactness and stability of the structure.

[0037] Furthermore, in order to facilitate the installation and fixation of the tooling, the present invention preferably has a plurality of fixing holes 251 formed on the groove 25 .

[0038] In the present invention, a mounting groove 31 is preferably provided on the top of the base 3 , and a mounting block 26 matching the mounting groove 31 is provided on the bottom of the positioning block 2 . The bottom surface of the mounting groove 31 is parallel to the upper surface of the base 3 .

[0039] In the present invention, threaded holes 32 corresponding to the fixing holes 251 are respectively opened on both sides of the installation groove 31, thereby enhancing the stability and durability of the tooling.

[0040] like Figure 5-8 As shown, first, the grinding support fixture of the present invention is positioned at the working position of the machine tool, and the end 11 of the medical drill bit 1 to be processed is tilted through the avoidance groove 22, and then the rod body 12 of the medical drill bit 1 is tilted and supported on the support seat 23; then, the position of the medical drill bit 1 to be processed is adjusted so that it is placed flat and fits tightly with the arc-shaped avoidance groove 24 and the support groove 231 to ensure stability during the processing; then, the medical drill bit 1 to be processed is moved backward to the chuck, and the medical drill bit 1 to be processed is fixed with the chuck to complete the clamping; finally, the machine tool is started for grinding until the processing is completed.

[0041] Through the above-mentioned clamping process, the present invention can achieve efficient and precise grinding of medical drill bits 1 while ensuring ease of operation and economy. First, the precise positioning of the fixture ensures stability and accuracy during the processing; furthermore, the oblique support design and tight fit adjustment enhance stability during processing; furthermore, the simplified and fast clamping process reduces clamping time and improves production efficiency, meeting the requirements of simple and fast operation in fixture design.

[0042] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
