Bearing processing device

Abstract

The invention belongs to the technical field of bearing equipment, in particular to a bearing processing device. The bearing processing device comprises a rack, a processing unit and a fastening unit,wherein the processing unit comprises a drive part, a processing part and a locking part; the drive part comprises a servo motor, a drive synchronous pulley and a driven synchronous pulley; a first rotary shaft is fixedly arranged between the step motor and the drive synchronous pulley; the center line of the drive synchronous pulley is mutually perpendicular to that of the driven synchronous pulley; an arc-shaped locking hole is axially formed in the teeth of the driven synchronous pulley; the processing part comprises a fixed block, wherein a gear and two racks are arranged in the fixed block, the gear is fastened with the driven synchronous pulley, the racks are engaged with the gear, and tools are arranged on the racks; the locking part comprises a cam and a pin roll, the cam and thedrive synchronous pulley are coaxially arranged, on end of the pin roll abuts against the cam, and the other end of the pin roll is opposite to the locking hole; and the fastening unit comprises a clamping jaw and a drive part used for controlling the clamping jaw to clamp and rotate. The bearing processing device realizes that a plurality of grooves with depths and widths are processed in a bearing at the same time, so that processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment, and in particular relates to a bearing processing device. 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 diameter smaller than the bearing. In the second mold of the circumference diameter, the ...

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 If the wall thickness of the bearing is thicker, the concave-convex grooves transferred will be shallower. At the same time, because the size of the mold is fixed, it is necessary to replace different molds to process grooves with a wide width, and the demand for molds also increases.
