Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to an automatic spacer assembly machine with a positioning structure. Background Art
[0002] Bearings are essential components in modern machinery and are widely used across various sectors of the national economy. Their precision, performance, lifespan, and reliability play a decisive role in the accuracy, performance, lifespan, and reliability of the main machine. They are used to determine the relative motion position of rotating shafts and other parts, providing support or guidance. The primary function of a bearing is to support a rotating shaft or other moving object, guiding rotational or translational motion and bearing the loads transmitted by the shaft or parts attached to it.
[0003] When the bearing is connected to other parts, a spacer is involved. Its main function is to prevent friction between the inner ring of the bearing and the connecting parts, thereby reducing friction and wear of the bearing, thereby improving the operating accuracy and reliability of the bearing and extending the bearing life. At the same time, some bearings have a large space reserved in the housing during production, and the purpose of bearing pairing is achieved by grinding the spacer.
[0004] In the process of realizing the present invention, the inventors found that the existing technology had the following problems: 1. Most bearings on the market are not equipped with spacers. Since the external connection equipment to be assembled cannot be paired, users have to do it by themselves when using it. Improper operation can easily cause wear on the internal bearings, so there is an urgent need for a bearing with assembled spacers; 2. Most spacers are installed manually, which cannot be quickly connected. The bearings and spacers are placed one by one, and manual installation and placement reduce installation efficiency.
