Machining device for joint bearing inner ring

Abstract

The invention discloses a machining device for a joint bearing inner ring. The device comprises a shell and a tool module, wherein the shell comprises a top part, a bottom part and a side part; the tool module comprises a screw rod and a knife rest; the screw rod is in threaded connection with the side part of the shell; the left end of the screw rod is spherical connection with the right end of the knife rest; the upper end of the knife rest is in sliding connection with the top part of the shell; a cavity is formed in the lower part of the knife rest; a push plate is arranged in the cavity;the two ends of the push plate are in sliding connection with the inner walls of the two ends of the knife rest correspondingly; a downward tool is fixedly connected to the left end of the push plate;a group of downward rolling wheel rods are fixedly connected to the push plate; rollers are arranged at the lower ends of the rolling wheel rods correspondingly; the upper end of the push plate is elastically connected with the top part of the shell; a group of upward profiling molds are arranged at the bottom part of the shell; the profiling molds are each provided with a profiling part which isthe same as the inner ring of a joint bearing in shape; the rolling wheels are in one-to-one correspondence with the profiling molds; and the rolling wheels are in rolling connection with the corresponding profiling molds. According to the machining device for the joint bearing inner ring, profiling machining is carried out on a lathe by utilizing the profiling molds, the machining precision is high, operation is convenient, and the economic benefits of enterprises are improved.

Description

technical field [0001] The invention belongs to the technical field of joint bearing processing, and in particular relates to a processing device for the inner ring of a joint bearing. Background technique [0002] Joint bearings are spherical sliding bearings, and the basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. The joint bearing is mainly composed of an outer ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand a large load. According to its different types and structures, it can bear radial load, axial load or combined load in both radial and axial directions. Since the outer spherical surface of the outer ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swinging motion, and can also be used for tilting motion within a certain angle range. When the misalignment between the suppo...

Problems solved by technology

In the process of processing the outer spherical surface of the inner ring of the joint bearing, the workpiece is usually clamped on the three chucks of the lathe, and the boring turning tool is clamped on the square tool table to process the inner spherical surface of the workpiece. The method is difficult to operate and the productivity is low. In order to save production costs and improve production efficiency, it is necessary to design a processing device for the outer ring of spherical plain bearings.
