An adjustable bearing processing device

Abstract

An adjustable bearing machining device comprises a machining base, an adjustable sleeve, an adjustable core rod, a downward-pressing device, a pin and a rotation device. The machining base is provided with kidney-shaped grooves and reinforcing ribs. The adjustable sleeve is composed of sleeve limiting pieces. The adjustable core rod is composed of core rod limiting pieces. The sleeve limiting pieces and the core rod limiting pieces are of arc shapes, and the bottoms of the sleeve limiting pieces and the core rod limiting pieces are connected with limiting blocks. Concave-convex channels are formed in the surface, close to the center of the machining base, of the core rod limiting pieces. The limiting blocks are installed in the kidney-shaped grooves in a sliding mode. The downward-pressing device is of a right-angle shape and is fixed to the edge of the machining base. The pin is installed at the upper end of the downward-pressing device. The rotation device is connected with the pin. According to the adjustable bearing machining device, forming dies are not needed, so that the cost of investment is saved; the problem that the numerous forming dies in the past occupy a large area of a field is solved, and the working environment is improved. The adjustable bearing machining device has the advantages of being high in transfer printing efficiency of bearings and suitable for machining the various bearings and components of other types.

Description

technical field [0001] The invention belongs to the field of processing and assembly equipment, and in particular relates to an adjustable processing device capable of processing bearings of different sizes according to requirements. Background technique [0002] The hydrodynamic bearing is a sliding bearing in which the liquid film formed by the dynamic pressure of the liquid lubricant separates the two friction surfaces and bears the load. The most important condition for generating the hydrodynamic pressure is that the two friction surfaces have sufficient relative motion speed. Therefore, the inner surface of the hydrodynamic bearing is often designed with concave-convex channels. In order to process the concave-convex groove on the inner surface of the bearing, the traditional method is: firstly, the upper and lower punches are used to clamp the bearing, the forming die is inserted into the inner circumference of the bearing, and then the bearing is inserted into a diam...

Problems solved by technology

[0003] It can be seen that the traditional method needs to select a suitable mold according to the size of the required bearing, and the wall thickness of the processed bearing needs to be considered when marking. If the wall thickness of the bearing is thin, it is not enough to support its elastic deformation; if The thicker the wall thickness of the bearing, the shallower the embossed grooves will be transferred.

[0004] And because the size of the bearings to be processed is different, the number of forming molds required is large, but only one forming mold is used for each processing, which easily leads to placing the forming molds everywhere, not only the site occupies a large area, but also the working environment Complicated, and the forming mold is easy to lose
