However, when cyclone milling ultra-long ball screws, the excessive length of the screw can easily lead to excessive axial runout during rotation, resulting in broken teeth in the machined thread and affecting the smoothness of the screw's operation. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a support device for ultra-long ball screw cyclone milling to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a support device for ultra-long ball screw cyclone milling, including a base fixed on the bed of a cyclone milling machine, a slide block slidably connected to the top of the base, a mounting seat fixed to one side of the slide block by bolts, a mounting groove opened on the top of the mounting seat, two rotating frames rotatably connected between the inner walls of the two sides of the mounting groove, a clamping rod frame fixed to one end of the rotating frame by bolts, an adjustment component that simultaneously drives the two rotating frames to rotate in opposite directions is provided in the mounting groove, and a power component that drives the mounting seat to move up and down is provided on the bottom inner wall of the base.

[0006] As a further embodiment of this utility model, the adjusting component includes a rotating shaft that rotates within the mounting groove. Two symmetrically distributed worm gears are keyed to the outer circumference of the rotating shaft. One end of each of the two rotating frames is welded with a worm wheel that rotates concentrically with the rotating frame, and the worm wheel meshes with the worm gear. A limiting component for auxiliary fixing of the rotating shaft is provided at the bottom of the mounting groove.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-4 This utility model provides a support device for ultra-long ball screw cyclone milling, including a base 1 fixed on the cyclone milling machine bed, a slide 2 slidably connected to the top of the base 1, a mounting seat 5 fixed to one side of the slide 2 by bolts, a mounting groove 10 opened on the top of the mounting seat 5, two rotating frames 15 rotatably connected between the inner walls of the two sides of the mounting groove 10, a clamping rod frame 16 fixed to one end of the rotating frame 15 by bolts, an adjustment component that simultaneously drives the two rotating frames 15 to rotate in opposite directions is provided in the mounting groove 10, a power component that drives the mounting seat 5 to move up and down is provided on the bottom inner wall of the base 1, a fixed frame 3 is provided on one side of the base 1, a support roller 9 is rotatably connected to the top of the fixed frame 3, and the fixed frame 3 is connected to the base 1 by a fixed component;

[0026] Both the support roller 9 and the clamping roller frame 16 are inclined to form a roller shaft similar to a "Mecanum wheel", which allows the shaft to be processed to move back and forth slightly during rotation, thus avoiding scratches on the shaft during movement.

[0027] In use, the base 1 is fixed on the bed of the cyclone milling machine and located on one side of the cyclone tool holder. The two rotating frames 15 are rotated and opened simultaneously by adjusting the components. The mounting base 5 is moved up or down by adjusting the components, so that the shaft to be processed is located between the two clamping roller frames 16.

[0028] Simultaneously, the top of the support roller 9 contacts the shaft to support it. The adjusting assembly drives the two rotating frames 15 to rotate, causing the two clamping roller frames 16 to clamp both sides of the shaft at the same time. The connecting line of the two clamping roller frames 16 is located above the shaft center, providing auxiliary limiting for the shaft. Thus, the clamping roller frames 16 and the support roller 9 assist in clamping the shaft, allowing the shaft to rotate while providing auxiliary limiting for the shaft, reducing the amount of runout during shaft rotation. This ensures that the lead screw is always within the specified error range during lead screw milling, improving the quality of lead screw processing.

[0029] In this utility model, the adjustment component includes a rotating shaft 12 that rotates in the mounting groove 10. Two symmetrically distributed worm gears 13 are keyed to the outer circumference of the rotating shaft 12. One end of the two rotating frames 15 is welded with a worm wheel 14 that rotates concentrically with the rotating frame 15, and the worm wheel 14 meshes with the worm gear 13. The bottom of the mounting groove 10 is provided with a limiting component for auxiliary fixing of the rotating shaft 12.

[0030] Rotating the shaft 12 causes the worm gear 13 to rotate, which in turn drives the worm wheel 14 to rotate, thereby driving the rotating frame 15 to rotate. The two symmetrically distributed worm gears 13 can cause the two worm wheels 14 to rotate in opposite directions, thereby enabling the two rotating frames 15 to rotate towards each other, improving the clamping accuracy of the device.

[0031] Meanwhile, the transmission between the worm gear 14 and the worm 13 is unidirectional, thereby fixing the angle of the rotating frame 15. The worm 13 is also fixed by the limiting component, which can prevent the worm 13 from rotating due to vibration generated by the milling machine itself, thus improving the stability of the device.

[0032] The limiting component includes a fixing plate 17 fixed to the inner wall of the bottom of the mounting groove 10. A plurality of placement grooves 18 are provided on one side of the fixing plate 17. An elastic ball 19 is placed in the placement groove 18. The elastic ball 19 is made of elastic material, preferably elastic rubber. A turntable 20 is welded to one end of the rotating shaft 12. A plurality of arc-shaped grooves 21 are provided on the opposite side of the turntable 20 and the fixing plate 17, and the elastic ball 19 is located in the arc-shaped grooves 21.

[0033] During the rotation of the shaft 12, the shaft 12 drives the turntable 20 to rotate, thereby causing the arc-shaped groove 21 to squeeze the elastic ball 19, causing the elastic ball 19 to deform and detach from the current arc-shaped groove 21. When another arc-shaped groove 21 rotates to the position of the elastic ball 19, the deformed elastic ball 19 resets and re-enters the arc-shaped groove 21, fixing the turntable 20, thereby fixing the shaft 12 and the worm gear 13, preventing the worm gear 13 from rotating due to vibration generated by the milling machine itself, and improving the fixed stability of the device.

[0034] The power assembly includes a threaded rod 4 that rotates on the inner wall of the bottom of the base 1. One end of the threaded rod 4 is inserted into the mounting base 5. A nut 11 is welded to the bottom of the mounting base 5, and the nut 11 is threadedly connected to the threaded rod 4.

[0035] Rotating the threaded rod 4, which engages with the nut 11, allows the nut 11 to move the mounting base 5 up or down, thereby adjusting the height of the mounting base 5. This enables the clamping rod frame 16 to stably clamp the shaft to be processed, improving the applicability of the device.

[0036] The fixing component includes a fixing screw 7 screwed onto one side of the base 1. A plurality of clearance grooves 8 are provided on one side of the fixing frame 3. The length of the clearance grooves 8 is much larger than the diameter of the fixing screw 7, so that the fixing frame 3 can be adjusted slightly, thereby ensuring that the support roller 9 is in contact with the shaft to be processed. When the support roller 9 is in contact with the shaft to be processed, the fixing screw 7 is passed through the clearance groove 8 and screwed into the base 1, so that the fixing screw 7 is fixed to the fixing frame 3, thereby completing the fixing of the fixing frame 3 and further improving the applicability of the device.

[0037] The top of the mounting base 5 is fixed with a baffle 6 by bolts to prevent waste from falling into the mounting groove 10 and causing abnormal wear on the meshing of the worm gear 14 and the worm 13.

[0038] It should be noted that the threaded rod 4, fixing screw 7, support roller 9, nut 11, rotating shaft 12, worm 13, worm wheel 14, clamping rod frame 16, and elastic ball 19 in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods, and will not be elaborated on here.

[0039] Among them, the clamping rod frame 16 is a combination of a connecting frame and a clamping rod, which can be set according to actual needs by those skilled in the art.

[0040] The working principle of this utility model is as follows: The base 1 is fixed on the bed of the cyclone milling machine and located on one side of the cyclone tool holder. The rotating shaft 12 is rotated, which drives the worm gear 13 to rotate, thereby driving the worm wheel 14 to rotate, and thus driving the rotating frame 15 to rotate and open.

[0041] Rotating the threaded rod 4, the threaded rod 4 cooperates with the nut 11 to make the nut 11 drive the mounting seat 5 to move up or down, thereby adjusting the height of the mounting seat 5 so that the shaft to be processed is located between the two clamping rollers 16;

[0042] It should be noted that in this application, the inner wall of the nut 11 is provided with an annular groove, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the annular groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the threaded rod surface at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0043] Adjust the position of the fixed frame 3 so that the top of the support roller 9 contacts the shaft to support it. Rotate the rotating shaft 12, which drives the worm gear 13 to rotate, thereby driving the worm wheel 14 to rotate, which in turn drives the rotating frame 15 to rotate. This allows the two clamping rollers 16 to clamp both sides of the shaft simultaneously, with the connecting line of the two clamping rollers 16 located above the shaft center, thus providing auxiliary limiting for the shaft. This allows the clamping rollers 16 and the support roller 9 to assist in clamping the shaft, enabling the shaft to rotate while providing auxiliary limiting for the shaft, reducing the amount of runout during shaft rotation, and thus ensuring that the lead screw milling always falls within the specified error range, improving the quality of lead screw machining.

[0044] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
