Description

Technical Field

[0001] The utility model relates to the technical field of a ball screw support seat, in particular to a ball screw support seat which is convenient for connecting a dust cover. Background Art

[0002] The ball screw support seat is divided into a fixed side and a supporting side. It is the core component of precision machinery, usually called a screw support seat. It can give full play to the functional advantages of the ultra-small support unit with its high rigidity, high strength and stability, so that mechanical equipment and bearings have high-precision use effects during operation.

[0003] For example, the publication number CN115319213A discloses a method for processing a ball screw support seat, including a support body, a connecting sleeve, a limiting plate, a mounting plate and a ferrule. First, a relatively rough support body, a connecting sleeve, a limiting plate, a mounting plate and a ferrule are produced through a mold, and then the surfaces and interiors of the support body, the connecting sleeve, the limiting plate, the mounting plate and the ferrule with relatively rough surfaces and inner cavities are initially polished to remove edges and burrs, and then an electric spark die head is produced according to the cavity size of the support body, the connecting sleeve, the limiting plate, the mounting plate and the ferrule. The processing method of the ball screw support seat, the support body, the limiting plate produced by this processing method The plate and the mounting plate are not only meticulously crafted but also highly precise, and can quickly fix the position of the ball screw, thereby ensuring the stability of the ball screw and thereby extending the service life of the ball screw. However, there are other deficiencies when using the ball screw support seat. First, the ball screw support seat limits the position of the bearing by using four screws to tighten the four right-angle mounting structures of the limit plate respectively. The screw tightening process is slow and requires a lot of manual labor, which affects the efficiency of disassembly and assembly and maintenance. In addition, no dust cover structure is provided, and the ball screw support seat cannot be dustproof, thereby reducing the service life. Therefore, there are still certain deficiencies when using the device. Utility Model Content
