DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Figure 1 As shown, when processing the collet 4 used in medical devices, it is necessary to process an eccentric angled special-shaped hole inside the collet 4. The existing tooling first fixes the collet 4, and then adjusts the overall angle of the tooling or the angle of the processing head to make the size of the special-shaped hole meet the requirements of the drawing.

[0025] In order to facilitate the processing of special-shaped holes on the collet 4, a vertical processing tool for the collet is designed, such as Figure 2 and 3 As shown, it includes a tooling body and a five-axis disk 1. The tooling body is fixedly set on the five-axis disk 1. The tooling body includes a fixing seat 2 and a positioning column 3. The fixing seat 2 is fixedly set on the five-axis disk 1 by bolts. A through hole 21 for accommodating the positioning column 3 is provided on the fixing seat 2, and a special-shaped hole 31 for accommodating the collet 4 is provided at the end of the positioning column 3.

[0026] During processing, first align the center of the five-axis disk 1, fix the fixing base 2 on the five-axis disk 1, then place the positioning column 3 in the through hole 21 of the fixing base 2, tighten the locking nut 35 screwed on the end of the positioning column 3, and the tightening force is 5N to fix the positioning column 3 in the fixing base 2 to prevent it from falling out. Then, open a special-shaped hole 31 at the processing end 32 of the positioning column 3, take out the collet 4 to be processed and place it in the special-shaped hole 31, and fix the five-axis disk 1 loaded with the collet 4 to the lathe. There is no need to change the angle or position of the working head to complete the processing of the special-shaped hole 31 on the collet 4, which is convenient and quick.

[0027] In order to ensure the stability of the collet 4 processing, a silicone sleeve can be set on the inner wall of the special-shaped hole 31. The silicone sleeve is provided with anti-slip grooves to increase the friction with the outer wall of the collet 4, so that the collet 4 has good stability after it is against the silicone sleeve.

[0028] like Figure 4 and 5As shown, the side of the fixing seat 2 close to the special-shaped hole 31 is the front end face 22, and the side away from the special-shaped hole 31 is the rear end face 23. The positioning column 3 has a processing end 32 and a locking end 33. The positioning column 3 extends from the front end face 22 into the through hole 21 and extends from the rear end face 23. A strip groove 24 is provided on the front end face 22 of the fixing seat 2. The strip groove 24 is connected to the through hole 21. The strip grooves 24 are symmetrically arranged on both sides of the through hole 21. The special-shaped hole 31 is provided at the processing end 32. The locking end 33 is locked to the rear end face 23 of the fixing seat 2 by a positioning piece. The processing end 32 of the positioning column 3 is provided with a positioning head that can be clamped on the outside of the through hole 21, and a positioning wedge surface 34 is provided on the contact surface between the positioning head and the through hole 21.

[0029] After the positioning post 3 is inserted into the through hole 21 of the fixing base 2, the processing end 32 of the positioning post 3 is secured by the cooperation of the positioning wedge surface 34 and the through hole 21. The locking end 33 of the positioning post 3 is then secured by a screwed lock nut 35, thereby confining the positioning post 3 entirely within the through hole 21 and preventing displacement during processing. To better lock the positioning head with the positioning wedge surface 34, strip grooves 24 are further provided on both sides of the through hole 21 on the front end surface 22 of the fixing base 2. When the positioning head is inserted into the through hole 21, the through hole 21 opens outward under the action of the strip grooves 24, thereby better clamping and fixing the positioning head.

[0030] To facilitate the locking of the positioning column 3, a locking nut 35 is used as the positioning member. The locking end 33 of the positioning column 3 is provided with an external thread that mates with the locking nut 35. This provides a strong locking force and prevents loosening. To further secure the positioning column 3, a plurality of screw holes 36 are provided around the locking nut 35. These screw holes 36 are arranged circumferentially around the center of the locking nut 35. Screws are screwed into the screw holes 36 until they contact the outer surface of the positioning column 3, further enhancing the stability of the positioning column 3.

[0031] like Figure 6 and 7 As shown, the collet 4 to be processed is placed in the special-shaped hole 31 of the positioning column 3. Under the action of the special-shaped hole 31, the collet 4 and the working surface are set at an angle. At this time, the working head of the lathe does not need to adjust the angle and can be directly processed horizontally to form the special-shaped hole 31 that meets the requirements of the drawing on the end face of the collet 4.

[0032] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all of them will fall within the scope of protection of the present invention.
