Description

Technical Field

[0001] The utility model relates to the technical field of ball screws, in particular to a wear-resistant ball screw positioning structure. Background Art

[0002] Ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or to convert torque into axial repetitive force, and it has the characteristics of high precision, reversibility and high efficiency. Due to its small friction resistance, ball screw is widely used in various industrial equipment and precision instruments. Ball screw consists of screw, nut, steel ball, preload plate, reverser and dust collector. Its function is to convert rotary motion into linear motion, which is a further extension and development of Aikem screw. The important significance of this development is to change the bearing from sliding motion to rolling motion. The history of people using screw for transmission is not very long. Traditional screws have always been poorly positioned and easy to damage. It was not until 1898 that people first tried to put steel balls between the nut and the screw to replace sliding friction with rolling friction to improve its poor positioning and easy damage. In 1940, ball screws were placed on automobile steering devices, which was a huge revolution in the application of ball screws and gradually replaced the traditional ACME screws. Until recently, ball screws have become one of the most widely used components in the industry.

[0003] The application number is CN201621447226.7, which discloses a highly wear-resistant ball screw, including a screw and a sleeve sleeved on the screw and capable of sliding axially with the screw, a first spiral groove is circumferentially arranged on the surface of the screw, the sleeve is axially transmitted to the first spiral groove, a clearance groove is arranged in the inner groove of the first spiral groove, and a second spiral groove for reducing friction and being misaligned with the first spiral groove is also arranged on the surface of the screw; it also includes a first electroplating layer electroplated on the surface of the screw, a nickel-plated layer electroplated on the surface of the electroplating layer, a second electroplating layer electroplated on the nickel-plated layer, and a polishing layer covering the second electroplating layer; a waterproof film for preventing water from entering the base is adhered to the side surface of the slide rail; the utility model has good wear resistance and a long service life.

[0004] Although the above utility model is electroplated on the surface of the screw rod with a first electroplating layer, electroplated on the surface of the electroplating layer with a nickel layer, electroplated on the second electroplating layer, and covered with a polishing layer on the second electroplating layer; the side surface of the slide rail is adhered with a waterproof film for preventing water from entering the base; the utility model has good wear resistance and a long service life, but there is a disadvantage that when the middle device is in use, it is unable to limit the distance position positioning, so that when the position management is required when using the device, manual measurement is required, which is time-consuming and labor-intensive, thereby reducing efficiency.

[0005] Therefore, it is necessary to install a positioning component on the device so that when using the device, the position distance and other parameters can be adjusted according to different usage scenarios. This can make the use of the device more flexible and more widely used without limitations. Utility Model Content
