Description

Technical Field

[0001] This utility model relates to the field of ball screw processing technology, specifically to a ball screw processing device for preventing axial bending. Background Technology

[0002] A ball screw is a high-precision transmission component that converts rotary motion into linear motion, widely used in machine tools, automation equipment, and precision instruments. It consists of a screw, nut, balls, and a reversing mechanism. Its core principle is that the balls roll between the helical raceways of the screw and nut, achieving relative motion between them, thereby converting rotational torque into axial thrust. A ball screw machining device designed to prevent axial bending of the workpiece during high-precision ball screw machining is a specialized piece of equipment. Its core principle is to optimize the balance of support, positioning, and cutting forces to prevent axial deformation of the screw due to its own weight, cutting forces, or clamping stress.

[0003] In existing technologies, traditional ball screw machining devices cannot guarantee the stability of the ball screw during machining. Due to its own weight, cutting forces, or clamping stress, the ball screw undergoes axial deformation during machining. This axial deformation directly leads to deviations in key precision indicators such as straightness and cylindricity of the finished product, causing problems such as transmission jamming and increased positioning errors after assembly, failing to meet the transmission accuracy requirements of precision equipment. Deformation also causes uneven stress between the ball screw and the cutting tool, accelerating tool wear and even chipping. This not only increases tool replacement frequency and costs but may also leave scratches and other defects on the ball screw surface, leading to increased scrap rates and wasted raw materials. Furthermore, accumulated deformation causes additional vibration during machining, affecting surface roughness and reducing product quality stability. During assembly, deformed ball screws require additional straightening or grinding, increasing labor costs. Forced installation can also exacerbate abnormal wear between components, shortening the overall lifespan of the equipment. Ultimately, this results in poor product consistency, making it difficult to enter high-precision applications and significantly reducing market competitiveness. Utility Model Content

[0004] The purpose of this invention is to provide a ball screw processing device that prevents axial bending, so as to solve the problem mentioned in the background art that ball screw processing devices that cannot guarantee the stability of screw processing lead to transmission jamming and increased positioning errors after assembly, resulting in a significant decrease in product quality stability and market competitiveness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ball screw processing device for preventing axial bending, comprising a processing device body, a connecting mounting cover fixedly connected to the processing device body, a processing cutter head disposed on the processing device body, a cleaning nozzle disposed on the connecting mounting cover, a mounting connecting seat disposed on the connecting mounting cover, a drive assembly disposed on the mounting connecting seat, an adjustment assembly disposed inside the processing device body, a main disc body disposed on the mounting connecting seat, a rotating knob rotatably connected inside the main disc body, a rotating conical shaft fixedly connected to the rotating knob, a rotating gear disc rotatably connected inside the main disc body, a clamping seat slidably connected inside the main disc body, a rotating connecting shaft rotatably connected inside the adjustment assembly, a connecting mounting seat fixedly connected to the rotating connecting shaft, a rotating bolt threadedly connected inside the connecting mounting seat, and a fixed support plate fixedly connected to the rotating bolt.

Operation is convenient, requiring no complex tools to complete clamping and adjustment, saving time and improving efficiency. Precise adjustment also ensures even force distribution on the machining head and lead screw, reducing tool wear, lowering scrap rate, saving costs, reducing vibration, improving surface roughness, ensuring quality stability, and enhancing competitiveness.

The connecting mounting base 812 on the rotating connecting shaft 811, the rotating bolt 813 threaded inside the connecting mounting base 812, and the fixed support plate 814 fixedly connected to the rotating bolt 813 are used to clamp and fix the ball screw to be processed by inserting it into the inside of the clamping seat 810. The rotating knob 807 drives the rotating cone shaft 808 to rotate inside the main disc body 806. The rotating cone shaft 808 drives the rotating gear disk 809 to rotate inside the main disc body 806. With the rotating gear disk 809 meshing with the clamping seat 810, the clamping seat 810 clamps and fixes the ball screw. The other end of the ball screw is inserted into the connecting mounting base 812, and the fixed support plate 814 is clamped and fixed by turning the rotating bolt 813.

[0018] Please see Figure 2-4 A further solution based on this embodiment is as follows: three clamping seats 810 are provided, and the three clamping seats 810 are evenly slidably connected inside the main disk body 806. By evenly slidably connecting the three clamping seats 810 inside the main disk body 806, the ball screw can be clamped and fixed from three different directions. By utilizing the principle of three-point positioning, the clamping stability of the screw is greatly improved, and the screw is prevented from shifting or bending axially due to uneven force during processing.

The sliding connecting seat 907 is slidably connected to the fixed limiting rod 908. By setting an adjustment assembly consisting of a second motor 901, a rotating threaded rod 902, and a sliding support seat 903, multi-dimensional adjustment of the processing head 3 and related components can be achieved. The second motor 901 drives the rotating threaded rod 902 to rotate, which can drive the sliding support seat 903 and the tool support seat 904 to move precisely, thereby achieving fine adjustment of the processing position.

[0024] Please see Figure 5-6 A further solution based on this embodiment is as follows: two fixed limiting rods 908 are provided, and the two fixed limiting rods 908 are symmetrically fixedly connected inside the processing device body 1. By symmetrically setting the two fixed limiting rods 908, the sliding connecting seat 907 can form double-sided support and guidance, so that the sliding connecting seat 907 is subjected to more balanced force during the sliding process, avoiding tilting or jamming, and effectively improving the stability and accuracy of the sliding process.
