Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, specifically a quick clamp changing device for screw tapping. Background Technology

[0002] The screw tapping quick-change chuck device is a high-efficiency tooling equipment for automated thread processing. It is designed to solve the efficiency bottleneck of frequent chuck changes in traditional tapping operations. The device adopts a modular quick-change structure, which can quickly switch between different specifications of taps, greatly improving the continuous tapping efficiency of multi-specification screws. It is suitable for precision thread processing scenarios such as automotive parts.

[0003] In existing technologies, screws typically require tapping during use, which necessitates machining using mechanical equipment. Screw tapping devices are commonly used for this purpose, and their applications are quite widespread. A screw tapping device usually works by feeding the screw to be tapped into a guide sleeve below the tap. A tapping motor drives a tapping shaft to rotate, which in turn rotates the tap, thus completing the tapping operation. A typical device consists of a frame, tapping motor, worktable, support base, tapping bottom support, tapping shaft, and tap. The tapping motor drives the tapping shaft, which in turn rotates the tap. The tapping bottom support ensures the stability of the worktable, and a support cylinder works in conjunction with the machine to complete the tapping process on the surface of the metal screw, thereby finishing the machining of the metal screw.

[0004] In current technology, screw tapping devices on the market typically operate using a tapping motor mounted on the bottom. The tapping motor drives a tapping shaft to rotate, which in turn drives a tap to rotate. This is achieved through the cooperation of a support cylinder seat, completing the tapping process on the surface metal screw. However, during the screw tapping process, traditional tapping devices are usually fixed in one place and cannot quickly adjust the tapping position for different screw models. This often requires stopping the machine for adjustments, resulting in wasted machine capacity and reduced work efficiency. Therefore, to address the above problems, a screw tapping quick clamp changing device is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a quick-change clamping device for screw tapping includes a worktable 3. A tapping frame 11 is mounted on one side of the worktable 3. A longitudinal guide rail 34 is mounted on one side surface of the tapping frame 11. A longitudinal screw 33 is mounted in the middle of the longitudinal guide rail 34. A longitudinal screw seat 32 is mounted in the middle of the longitudinal screw 33. A longitudinal clamping plate 31 is mounted on the surface of the longitudinal screw seat 32. A slide rail mounting base 18 is mounted on the other side surface of the tapping frame 11. A first slide rail 19 is mounted on the surface of the slide rail 18. A first slider 20 is mounted on the surface of the first slide rail 19. A middle layer plate 21 is mounted on top of block 20. A longitudinal coupling 29 is mounted on one end of the longitudinal lead screw 33, and a longitudinal motor 30 is mounted on one end of the longitudinal coupling 29. A transverse guide rail 26 is mounted on the surface of the middle layer plate 21. A transverse lead screw 22 is mounted in the middle of the transverse guide rail 26. A transverse lead screw seat 25 is mounted in the middle of the transverse lead screw 22. A transverse clamping plate 36 is mounted on the surface of the transverse lead screw seat 25. A transverse coupling 27 is connected to one end of the transverse lead screw 22. A transverse motor 28 is mounted on one end of the transverse coupling 27. A drag chain 24 is mounted on the top of the middle layer plate 21.

[0023] In current technology, screw tapping devices on the market typically operate using a tapping motor 49 mounted on the bottom. The tapping motor 49 drives a tapping shaft 54 ​​to rotate, which in turn drives a tap 53 to rotate. This, in conjunction with a support cylinder seat 16, completes the tapping of the surface metal screw. However, during the tapping process, traditional tapping devices are usually fixed in one place, making it impossible to quickly adjust the tapping position for different screw types. This often requires stopping the machine for adjustments, resulting in wasted machine capacity and reduced work efficiency. Therefore, to address these issues, a new... A quick-change clamping device for screw tapping operates by placing the screw in the middle of the clamp 52 above the worktable 3. The horizontal motor 28 rotates the horizontal lead screw 22, which in turn adjusts the position of the horizontal lead screw holder 25. This, in turn, causes the horizontal clamping plate 36 to move laterally, thus changing the lateral position of the tapping device. When the longitudinal position of the tapping device needs to be adjusted, the vertical motor 30 rotates the vertical lead screw 33 connected to the end of the motor shaft. The vertical lead screw holder 32 in the middle engages with the vertical lead screw 32 to complete the displacement of the tapping device.

[0024] Furthermore, a second slide rail 37 is installed below the middle layer plate 21, and a second slider 35 is mounted on the surface of the second slide rail 37. A front panel 17 is installed on one side surface of the tapping machine frame 11, a front mounting plate 13 is installed on the surface of the front panel 17, a connecting back plate 44 is installed on the surface of the front mounting plate 13, a vertical guide rail 55 is mounted on one side surface of the connecting back plate 44, a vertical lead screw 38 is installed in the middle of the vertical guide rail 55, a vertical lead screw seat 39 is installed in the middle of the vertical lead screw 38, a vertical clamping plate 40 is installed on the surface of the vertical lead screw seat 39, a vertical coupling 42 is connected to one end of the vertical lead screw 38, and a vertical motor 41 is installed at one end of the vertical coupling 42. A frame 2 is installed below the worktable 3, a universal wheel 8 is mounted at the bottom of the frame 2, and a support foot pad 1 is mounted on one side of the universal wheel 8. A support base 7 is installed on one side of the workbench 3. A straightening frame 6 is mounted on the top of the support base 7. A base 15 is installed in the middle of the workbench 3. A tapping bottom support 14 is installed on the surface of the base 15. A support cylinder seat 16 is mounted on one side of the tapping bottom support 14. A middle support 12 is installed in the middle of the tapping machine frame 11. A top cover plate 5 is installed on the top of the middle support 12. A tapping back plate 48 is installed on the surface of the vertical clamping plate 40. Limit seats 46 are mounted on both sides of the tapping back plate 48. A motor mounting plate 50 is mounted on the top of the limit seats 46. A tapping motor 49 is mounted on the surface of the motor mounting plate 50. A tapping shaft 54 ​​is installed at the end of the tapping motor 49. A tap 53 is mounted below the tapping shaft 54. A tapping base plate 51 is installed below the limit seats 46. A clamp 52 is mounted in the middle of the tapping base plate 51.

[0025] During operation, when performing tapping operations, the tapping device often needs to be adjusted due to different screw types. The output end of the vertical motor 41 is rotated, which drives the vertical coupling 42 below to work, thereby driving the vertical clamping plate 40 below to move up and down repeatedly. This causes the tapping device mounted on the surface of the vertical clamping plate 40 to adjust its position, thus completing the overall tapping operation.

[0026] Working principle: In current technology, screw tapping devices on the market typically operate using a tapping motor 49 mounted on the bottom. The tapping motor 49 drives the tapping shaft 54 ​​to rotate, which in turn drives the tap 53 to rotate. This, in conjunction with the support cylinder seat 16, completes the tapping of the surface metal screw. However, during screw tapping, traditional tapping devices are usually fixed in one place, making it impossible to quickly adjust the tapping position for different screw types. This often requires stopping the machine for adjustments, resulting in wasted machine capacity and reduced work efficiency. Therefore, to address these issues, a quick-change clamping device for screw tapping is proposed. During screw tapping, the screw is placed in the center of the clamp 52 above the worktable 3, and the horizontal motor 28 operates, driving the horizontal lead screw 2... 2. Rotation causes the horizontal thread holder 25 to adjust its position, which in turn causes the horizontal clamping plate 36 to move laterally, thus changing the lateral position of the tapping device. When the longitudinal position of the tapping device needs to be adjusted, the longitudinal motor 30 is used. The rotation of the motor shaft causes the longitudinal thread rod 33 connected to the end to rotate, which is coordinated with the longitudinal thread holder 32 in the middle to complete the displacement of the tapping device. During tapping operations, the tapping device often needs to be adjusted due to different screw types. The output end of the vertical motor 41 is rotated, which drives the lower vertical coupling 42 to operate, thereby causing the lower vertical clamping plate 40 to move up and down repeatedly, thus adjusting the position of the tapping device mounted on the surface of the vertical clamping plate 40, thus completing the overall tapping operation.
