Introduction and installation of advertising engraving machine ball screw, Jinan Acut CNC Equipment Co.,Ltd based cooperative research and development, promoting high-tech, high-quality concept in the NC field of advertising products, laser, woodworking, etc. in research and manufacturing, with a forge ahead, to share the results of the fighting spirit and the credibility of the first, service-oriented principle of service, steady and sustainable development.
 
        We here want to ask, on a "wood engraving machine engraving machine processing software for what relief?" We all learn it?
? The ad engraving machine ball screw profile and installation, what does Here we have to explain in detail:
Let's look at advertising engraving machine ball screw:
Advertising engraving machine ball screw is rotary motion into linear motion, or linear motion into rotary motion of the ideal product. Advertising engraving machine ball screw deputy has a variety of structural types. Press ball circulation cycle is divided into an outer and inner loop into two categories. Outer loop back to Pearl Used intubation more, the inner loop back to bead-shaped groove slug Used waist style more. Press the cross-sectional shape of the track is divided into single thread and double arc arc two kinds truncate. As the double-arc-shaped cross-section is greater than the axial stiffness of a single arc-shaped cross-section, so now widely used double arc truncate screw. Press preload form can be divided into single nut without preload single nut preload displacement lead, radial ball to increase preload single nut, washer double nut preload, poor teeth double nut preload, double preload nut threads. CNC machine tools commonly used double preload nut, washer type, its preload is generally 1/3 of the axial load. The ball screw nut and slide bars Compare has many advantages: high transmission efficiency, high sensitivity, stable transmission: wear, long life; can eliminate the axial gap and improve the axial stiffness.
Here to introduce installation advertising engraving machine ball screw:
1. Using a screw fixing nut rotatable drive way at this time, WG93UOL nut while rotating, the edge of a fixed screw for axial movement: As the screw does not move, can be avoided by the critical speed limits, avoiding the elongated ball screw high-speed operation when problems arise. Nut inertia, flexible movement, can achieve high speed. This approach may be applied to larger pretension of the screw, screw improve support stiffness, heat distortion compensation screw.
2. Push a double-free way screw end fixed, one end free. Fixed end bearings withstand the axial and radial forces. Short screw --- The advantage of this approach for supporting small stroke: easier assembly, less affected by geometrical accuracy, suitable for short and vertical screw screw; drawback: the distance between the point of smaller, less rigid.
3. Push with a screw manner is supported at one end fixed and the other end of the support. Fixed end bearings withstand the axial and radial forces; supporting end bearings support radial forces only, but also for the small amount of axial float, to avoid or reduce the bending of the screw due to weight appears. Meanwhile screw heat distortion free to stretch to an end.
4. Push one pair of dual-way screw push both ends fixed. Fixed end bearings can withstand axial and radial forces, supported this approach can be applied to the appropriate screw pretension, enhance screw bearing stiffness, thermal compensation can screw portion is deformed. Its advantages are: the larger the distance between the point of rigidity preferred; Disadvantages: more vulnerable to a combination of geometric precision parts affected.
On the final: CNC equipment used in the industry's most widely used in industrial machinery, but also in real life more and more, so it is irreplaceable decided it would play an important role as people's lives ! integral part of advertising engraving machine ball screw installation methods in general there are four, two-way push-bearing screw one end fixed and the other end of the support; fixed by screw, nut rotation transmission mode; double push one pair push mode screw both ends fixed; a free two-way push screw end fixed, one end of freedom, through this article, you also learn a ball screw installation method, then you rush to practice it!
