Technical Field

[0001] This utility model belongs to the technical field of multi-hole drilling processing devices, specifically referring to a cam multi-hole drilling processing device for sewing equipment. Background Technology

[0002] The cam in a sewing machine controls the movement of the needle. Through the design and movement of the cam, the sewing machine can make the needle move up and down in specific ways to complete different types of sewing operations, such as straight stitching, sewing buttons, and buttonholes. The shape and size of the cam affect the needle's trajectory and speed, thus affecting the sewing effect and quality.

[0003] Existing cams require drilling during processing. These holes allow the cam to be fixed to other components, enabling the cam's motion to be transmitted to other components to achieve specific sewing actions. However, the spacing between the drill rods in existing drilling devices is not easy to adjust, reducing efficiency. Furthermore, the drill rods are not easy to disassemble and replace.

The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, this utility model proposes a cam-based multi-hole drilling device for sewing equipment, comprising a worktable 1, a support 2, a telescopic component 3, and a drilling assembly 4. The support 2 is mounted on the worktable 1, the telescopic component 3 is slidably mounted on the support 2, and the drilling assembly 4 is mounted on the telescopic component 3. The drilling assembly 4 includes a support frame 5, a fixed shaft 6, drill rods 7, and a spacing adjustment component 8. The support frame 5 is mounted on the telescopic component 3, the spacing adjustment component 8 is mounted on the support frame 5, the fixed shaft 6 is mounted on the spacing adjustment component 8 and has two sets, the drill rods 7 are detachably mounted on the fixed shaft 6, and the spacing adjustment component 8 can adjust the distance between the two drill rods 7.

[0021] The spacing adjustment component 8 includes a lead screw 9 and a lead screw pair 10. The inner side wall of the support frame 5 is provided with a fixing plate 11. The two ends of the lead screw 9 are rotatably disposed between the support frame 5 and the fixing plate 11. A sliding rod 12 is provided between the fixing plate 11 and the support frame 5. The lead screw pair 10 is threadedly connected to the lead screw 9 and slidably sleeved on the sliding rod 12. There are two sets of fixed shafts 6. The top ends of the two sets of fixed shafts 6 respectively rotatably pass through the lead screw pair 10 and the fixing plate 11 and extend out. The side wall of the support frame 5 is provided with a handle 13. The end of the handle 13 rotatably passes through the support frame 5 and is connected to the lead screw 9. Rotating the handle 13 drives the lead screw 9 to rotate, thereby changing the distance between the two fixed shafts 6 driven by the lead screw pair 10. The distance between the drill rods 7 on the two fixed shafts 6 can be adjusted.

[0022] The fixed shaft 6 is provided with a linkage 14, which includes a first linkage 15 and a second linkage 16. One end of the first linkage 15 and the second linkage 16 are respectively rotatably sleeved on the extended ends of the two fixed shafts 6 through bearings. The other ends of the first linkage 15 and the second linkage 16 are rotatably connected by shafts. Gear 17 is fixedly sleeved on both fixed shafts 6. Gear 28 is rotatably mounted on the other end of the first linkage 15 and the second linkage 16. Gear 218 meshes with both gears 17. The support frame 5 is provided with a drive motor 19. The output end of the drive motor 19 rotatably passes through the support frame 5 and is connected to the fixed shaft 6 on the fixed plate 11. When the drive motor 19 is started, the fixed shaft 6 can be driven to rotate. The other fixed shaft 6 rotates synchronously through the transmission of gear 17 and gear 218. The drill rod 7 on the two fixed shafts 6 can drill holes. When the lead screw pair 10 moves, the included angle between the first linkage 15 and the second linkage 16 changes to adjust the distance.

[0023] The bottom wall of the fixed shaft 6 is provided with a through hole 20, and the side wall of the fixed shaft 6 is provided with a positioning groove 21. The positioning groove 21 is connected to the through hole 20. The side wall of the drill rod 7 is fixed with a stud 22. The top of the drill rod 7 is inserted into the through hole 20, and the stud 22 is inserted into the positioning groove 21. A positioning cap 23 is threaded onto the stud 22. The end of the positioning cap 23 is rotated into the positioning groove 21. The positioning cap 23 is T-shaped. The top of the positioning groove 21 is round and the bottom is rectangular. When replacing the drill rod 7, the positioning cap 23 can be unscrewed from the positioning groove 21, that is, the drill rod 7 can be taken out from the through hole 20. The number of drill rods 7 can be adjusted as needed, and replacement is also convenient.

[0024] The bracket 2 is provided with an electric slide rail 24 at the top, and an electric slide rail 25 is provided on the slide base of the electric slide rail 24. The telescopic member 3 is provided on the slide base of the electric slide rail 25. The front and rear positions of the drill rod 7 can be adjusted by the electric slide rail 24, and the horizontal position of the drill rod 7 can be adjusted by the electric slide rail 25.

[0025] The telescopic component 3 includes an electric telescopic rod 26. The fixed end of the electric telescopic rod 26 is located on the slide seat of the electric slide rail 25, and the movable end of the electric telescopic rod 26 is located on the top wall of the support frame 5. The electric telescopic rod 26 can drive the support frame 5 to move up and down, thereby driving the drill rod 7 to move up and down to drill.

[0026] In practical use, starting the drive motor 19 can drive the fixed shaft 6 to rotate, while the other fixed shaft 6 rotates synchronously through gear 17 and gear 28. Then the drill rod 7 on the two fixed shafts 6 can rotate, the electric telescopic rod 26 extends, and the drill rod 7 moves down to drill the cam.

[0027] When adjusting the distance between the two drill rods 7, rotate the handle 13 to drive the lead screw 9 to rotate. The lead screw pair 10 then changes the distance between the two fixed shafts 6, thus adjusting the distance between the drill rods 7 on the two fixed shafts 6. When the lead screw pair 10 moves, the included angle between connecting rod 15 and connecting rod 2 16 changes, and gear 17 and gear 2 18 remain engaged, thus completing the adjustment of the distance between the two drill rods 7.

[0028] When replacing the drill rod 7, the positioning cap 23 can be unscrewed from the positioning groove 21, that is, the drill rod 7 can be taken out from the through hole 20. The number of drill rods 7 can be adjusted as needed, and replacement is also convenient.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
