[0002] Screw machining rotary milling equipment is a high-efficiency and precise CNC machine tool, widely used in industries such as machine tool lead screws, valve lead screws, injection molding machine extrusion screws, and packaging machine metering screws. This equipment achieves efficient and high-precision machining of screw-type parts through rotary milling technology.

[0003] When machining screw threads, rotary milling equipment is used. However, when using rotary milling equipment, one end of the screw needs to be clamped and fixed before the screw can be slotted. During rotary milling, a certain amount of compressive force is applied to the screw, which may cause one end of the screw to loosen, thus affecting the machining accuracy. Therefore, we propose a rotary milling equipment that facilitates screw thread machining. Utility Model Content

[0017] 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 protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a rotary milling device for easy screw thread processing, including a work plate 1, a support platform 2 fixedly installed at the bottom of the work plate 1, an end clamping mechanism 3 fixedly installed on one side of the top of the work plate 1 to clamp and rotate one end of the screw, an end positioning mechanism 4 for contacting and supporting the other end of the screw on the other side of the top of the work plate 1, a rotary milling mechanism 5 for external rotary milling of the screw on the work plate 1, and a support mechanism 6 for supporting and limiting the rotary milling position of screws of different diameters on one side of the rotary milling mechanism 5.

[0019] The end clamping mechanism 3 can clamp and rotate one end of the screw to be processed. The end positioning mechanism 4 can support and limit the other end of the screw. The milling mechanism 5 is set outside the screw, which facilitates thread milling of the screw. When the milling mechanism 5 moves to mill, the support mechanism 6 can move with it. This can prevent the milling mechanism 5 from applying excessive pressure to the screw during operation, which would cause the screw to loosen and detach from the end clamping mechanism 3, thus ensuring the accuracy of screw processing.

[0020] Please see Figure 1 and Figure 2The end clamping mechanism 3 includes a first mounting frame 7, a drive motor 8, a three-jaw chuck 9, and a clamping block 10. The first mounting frame 7 is fixedly mounted on the working plate 1. The drive motor 8 is fixedly mounted on one side of the first mounting frame 7. The output end of the drive motor 8 is fixedly connected to the three-jaw chuck 9. The clamping block 10 is fixedly mounted at the jaw position of the three-jaw chuck 9.

[0021] The screw to be processed is placed between three sets of clamping blocks 10. Then, the three-jaw chuck 9 works to clamp and fix the screw using the three sets of clamping blocks 10. The drive motor 8 can drive the three-jaw chuck 9 and the screw to rotate.

[0022] Please see Figure 1 The end positioning mechanism 4 includes a second mounting bracket 11, a drive cylinder 12, a moving plate 15, a rotating seat 16, and a positioning pin 17. The top of the working plate 1 is fixedly mounted with the drive cylinder 12 via the second mounting bracket 11. Two sets of slide rails 13 are fixedly mounted on the top of the working plate 1. The moving plate 15 is slidably connected to the slide rails 13 via a slider 14. The positioning pin 17 is rotatably connected to one side of the moving plate 15 via the rotating seat 16. The output end of the drive cylinder 12 is fixedly connected to the moving plate 15.

[0023] After one end of the screw is clamped and fixed, the drive cylinder 12 operates, pushing the moving plate 15 to move forward through the slide rail 13 and the slider 14. At this time, the positioning pin 17 can contact the other end of the screw, thus completing the support and positioning of the other end of the screw. Subsequently, as the screw rotates, the positioning pin 17 can rotate along the rotating seat 16.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The rotary milling mechanism 5 includes a first screw slide 18, a connecting plate 19, a second screw slide 20, and a milling cutter disc 21. Two sets of first screw slides 18 are fixedly installed on one side of the working plate 1. The connecting plate 19 is fixedly installed on the top of the first screw slide 18. The second screw slide 20 is fixedly installed on one side of the connecting plate 19. The milling cutter disc 21 is fixedly installed on one side of the second screw slide 20.

[0025] The milling cutter disc 21 can be set outside the screw. The first screw slide 18 can drive the milling cutter disc 21 to contact the outside of the screw. Then the milling cutter disc 21 works to mill the screw thread. The second screw slide 20 can drive the milling cutter disc 21 to move left and right, so that the screw can be milled in all directions.

[0026] Please see Figure 1 and Figure 4The support mechanism 6 includes a fixed plate 22, a connecting seat 23, an adjusting screw 24, a connecting rod 26, and a support sleeve 27. Two sets of connecting seats 23 are fixedly installed on the second screw slide table 20 through the fixed plate 22. The adjusting screw 24 is rotatably connected to the connecting seat 23. The adjusting screw 24 is threadedly connected to the outside of the threaded sleeve 25. The support sleeve 27 is fixedly connected to the outside of the threaded sleeve 25 through the connecting rod 26. One side of the connecting rod 26 is in contact with the fixed plate 22.

[0027] The support sleeve 27 can move synchronously with the second screw slide 20, and the two sets of support sleeves 27 are set on both sides of the milling cutter disc 21. This can support the screw when the milling cutter disc 21 applies pressure. Then, when the diameter of the screw to be milled is different, the screw 24 is rotated to adjust the screw, which drives the threaded sleeve 25, the connecting rod 26 and the support sleeve 27 to move up and down. This allows the inside of the support sleeve 27 to contact the outer wall of the screw, thereby preventing the screw from disengaging from the three-jaw chuck 9 and the clamping block 10 when applying pressure.

[0028] Please see Figure 1 and Figure 3 A support base 28 is fixedly installed on the top of the working plate 1. The top of the support base 28 is rotatably connected to a plurality of support balls 29 that contact the bottom of the three-jaw chuck 9. The support balls 29 rotatably installed on the support base 28 can contact the bottom of the three-jaw chuck 9, so that there will be no shaking or displacement when the three-jaw chuck 9 rotates.

[0029] In use, firstly, the end clamping mechanism 3 clamps and rotates one end of the screw to be machined. Then, the end positioning mechanism 4 supports and limits the other end of the screw. Next, the milling mechanism 5 is located outside the screw, facilitating thread milling. While the milling mechanism 5 moves, the support mechanism 6 moves accordingly to prevent excessive pressure on the screw, which could cause it to loosen and detach from the end clamping mechanism 3, ensuring the machining accuracy. The screw to be machined is positioned between three sets of clamping blocks 10. Then, the three-jaw chuck 9 operates, using the three sets of clamping blocks 10 to clamp and fix the screw. The drive motor 8 drives the three-jaw chuck 9 and the screw to rotate. After one end of the screw is clamped and fixed, the drive cylinder 12 operates, pushing the moving plate 15 forward via the slide rail 13 and slider 14. At this point, the positioning pin 17 contacts the other end of the screw, thus allowing the screw to be milled. After the other end of the screw is supported and positioned, the positioning pin 17 rotates along the rotating seat 16 as the screw rotates. The milling cutter disc 21 can be set outside the screw. The first screw slide 18 can drive the milling cutter disc 21 to contact the outside of the screw. Then the milling cutter disc 21 works to mill the screw thread. The second screw slide 20 can drive the milling cutter disc 21 to move left and right, so that the screw can be milled in all directions. The support sleeve 27 can move synchronously with the second screw slide 20. The two sets of support sleeves 27 are set on both sides of the milling cutter disc 21. This can support the screw when the milling cutter disc 21 applies pressure. Then, when the diameter of the screw to be milled is different, the screw 24 is rotated to adjust the screw, which drives the threaded sleeve 25, connecting rod 26 and support sleeve 27 to move up and down. This allows the inside of the support sleeve 27 to contact the outer wall of the screw, thus preventing the screw from disengaging from the three-jaw chuck 9 and clamping block 10 when pressure is applied.
