Figure 1 The lens barrel 200 shown needs to ensure the perpendicularity of the first end face 201 to the circumferential surface 202, and also the parallelism of the first end face 201 to the second end face 203. To meet these requirements, CNC machining involves simultaneously machining the first end face 201, the circumferential surface 202, and the second end face 203. When machining the circumferential surface 202 and the second end face 203, the chuck extends from the side of the first end face 201 to clamp the area between the first end face 201 and the second end face 203. Therefore, during the machining of the first end face 201... When machining the end face 201, the machining tool cannot be inserted from the side of the first end face 201. To solve this problem, the machining tool is inserted from the side of the circumferential surface 202 to the side of the first end face 201 to machine the first end face 201. Therefore, it is necessary to design a special tool that extends into the lens barrel 20 from the side of the circumferential surface 202 and extends out of the first end face 201 to machine the first end face 201, while ensuring the perpendicularity requirement between the first end face 201 and the circumferential surface 202, and at the same time ensuring the parallelism requirement between the first end face 201 and the second end face 203.

Detailed Implementation Methods

[0026] Please refer to Figures 1-5 This embodiment is a special machining tool 100 for lens barrels, which is used to machine the first end face 201 of the lens barrel 200 and the inner hole of the lens barrel 200. The special machining tool 100 for lens barrels includes a tool holder 1, a mounting head 2 disposed at one end of the tool holder 1 and extending out of the first end face 201, and a machining tool 3 disposed on the mounting head 2. The machining tool 3 is detachably mounted on the mounting head 2 by a locking member 4.

[0027] The tool holder 1 consists of, from bottom to top, a mounting part 11, a middle reinforcing body 12, and an upper contouring part 13. The mounting part 11 is connected to the CNC machine tool, and the contouring part 13 is connected to the mounting head 2. Because the upper end of the lens barrel 200 has a small aperture and the lower end has a large aperture, the contouring part 13 needs to extend into the upper end of the lens barrel 200 with the smaller aperture. Therefore, the diameter of the contouring part 13 is relatively small. To ensure the overall strength of the tool holder 1, the diameter of the reinforcing body 12 is larger than the diameter of the contouring part 13. Since the lower end of the lens barrel 200 has a larger diameter, the diameter of the reinforcing body 12 can be adaptively set according to the diameter of the lower end of the lens barrel.

[0028] When machining the first end face 201 of the lens barrel 200, the end of the tool holder 1 with the machining tool 3 is first inserted into the center of the lens barrel 200, and the mounting head 2 is extended out of the first end face 201. Then, the tool holder 1 is moved axially so that the machining tool 3 contacts the first end face 201. The machining tool 3 processes from the inner circle to the outer circle of the first end face 201. Therefore, during the machining process, the tool holder 1 will move closer to the inner wall of the lens barrel 200. The distance that the tool holder 1 moves is equal to the distance that the machining tool 3 moves from the inner circle to the outer circle of the first end face 201. In order to ensure the strength of the tool holder 1, the diameter of the reinforcing body 12 is enlarged. However, in order to avoid interference between the reinforcing body 12 and the inside of the lens barrel 200 during the movement, the reinforcing body 12 is provided with a clearance notch 121 below the machining tool 3. When the machining tool 3 moves from the inner circle to the outer circle of the first end face 201, the lens barrel 200 is close to the clearance notch 121 and will not interfere with the reinforcing body 12. Because the diameter of the contouring part 13 is small, in order to ensure the strength of the contouring part 13, a contouring reinforcement part 131 is provided below the machining tool 3. The shape of the contouring reinforcement part 131 is contoured to the upper end of the lens barrel 200, but the diameter of the contouring reinforcement part 131 is smaller than the aperture of the upper end of the lens barrel 200, so that the tool holder 1 can be smoothly inserted from the lower end of the lens barrel 200 to the upper end of the lens barrel 200. When the machining tool 3 moves from the inner ring to the outer ring of the first end face 201, the lens barrel 200 approaches the clearance notch 121 and the contouring reinforcement part 131 of the tool holder 1, but the lens barrel 200 will not interfere with the tool holder 1.

[0029] The mounting head 2 protrudes from the outer periphery of the contouring part 13. One side of the mounting head 2 has a contouring mounting groove 21 for mounting the machining tool 3, and the other side has a first mounting hole 22 that fits into the locking member 4 and extends into the contouring mounting groove 21. The machining tool 3 has a second mounting hole 31 that fits into the locking member 4. The locking member 4 is a screw, which passes through the first mounting hole 22 and the second mounting hole 31. Tightening the screw fixes the machining tool 3 onto the mounting head 2, and loosening the screw allows for easy removal of the machining tool from the mounting head 2. This is simple and convenient. In other embodiments, the locking member can also be a pin or bolt, etc., and is not limited here.

[0030] The machining cutter 3 has a hexahedral structure, with the intersection of every two faces forming a straight line and the intersection of every three faces forming a sharp angle. The machining cutter 3 is provided with a first cutting edge 32 for machining the first end face 201 of the lens barrel 200 and a second cutting edge 33 for machining the inner hole of the lens barrel 200.

[0031] The first cutting edge 32 is formed by the intersection of the first plane 34 on the right side and the second plane 35 on the bottom surface, and the second cutting edge 33 is formed by the intersection of the first plane 34 on the right side and the third plane 36 on the rear side. Therefore, the first cutting edge 32 and the second cutting edge 33 are located on adjacent sides of the first plane 34, respectively. Both the first cutting edge 32 and the second cutting edge 33 are straight lines, and the first cutting edge 32 is set at an angle to the central axis of the tool holder 1 and at an angle to the radial line of the tool holder 1. Preferably, the angle between the first cutting edge 32 and the central axis of the tool holder 1 is 80 to 82°, and the angle between the second cutting edge 33 and the radial line of the tool holder 1 is 80 to 82°. This is to ensure that the first cutting edge 32 and the second cutting edge 33 form a natural chip removal space when machining the end face and inner hole of the lens barrel 200, which facilitates the discharge of cutting material. The second plane 35 is set at an angle to the horizontal plane, and the third plane 36 is set at an angle to the vertical plane. The three planes, the first plane 34, the second plane 35, and the third plane 36, intersect to form a cutting tip 37. The cutting tip 37 is in a low position so that the machining can be concentrated on the cutting tip 37, which can improve the machining accuracy.

[0032] When using the lens barrel-specific machining tool 100 provided in this solution, when machining the first end face 201 of the lens barrel 200, first insert the end of the tool holder 1 with the machining tool 3 into the center of the inside of the lens barrel 200, and make the mounting head 2 extend out of the first end face 201. Then, move the tool holder 1 axially so that the machining tool 3 contacts the first end face 201. The machining tool 3 processes from the inner circle to the outer circle of the first end face 201 to complete the machining of the first end face 201. If it is necessary to machine the hole wall of the lens barrel 200, first insert the end of the tool holder 1 with the machining tool 3 into the center of the inside of the lens barrel 200, and make the mounting head 2 extend into the inside of the lens barrel 200. Then, move the tool holder 1 radially so that the machining tool 3 contacts the inner wall of the lens barrel 200. The machining tool 3 processes the inner wall of the lens barrel.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
