Ball socket machining device for inner ring of socket curved groove ball bearing

Abstract

The utility model discloses a ball socket machining device for an inner ring of a socket curved groove ball bearing, and belongs to the field of mechanical engineering. In order to overcome the defects of low working efficiency, large workload, incapability of effectively ensuring the precision and the like of ball socket machining of the inner ring of the socket curved groove ball bearing. The machining device comprises a base, a rapid clamping device, a set of ball socket milling devices arranged in the circumferential direction, a set of indexing precision control blocks and a feeding precision control mechanism and the like; and an air cylinder is used for independent feeding, and a motor is used for driving a spherical milling cutter to conduct independent milling. The machining device for the inner ring of the socket curved groove ball bearing has the following advantages that (1) a plurality of ball sockets can be machined at the same time at a time, and time is saved; (2) the indexing precision of the ball sockets is improved by using a movable positioning block; and (3) the feeding power of the air cylinder is flexible force, so that the impact of the milling cutter can beavoided.

Description

technical field [0001] The patent relates to a processing device for an inner ring of a ball bearing, which belongs to the field of mechanical parts, and in particular to a processing device for a ball socket of an inner ring of a socket curved groove ball bearing. Background technique [0002] Curve ball bearings are widely used in crop straw extrusion and rubbing equipment, and are often used in the development and design of agricultural equipment; the inner ring of the bearing involved in this design is a ball-and-socket type, so the processing method It is different from the bearing inner ring with traditional groove structure; the traditional ball socket processing method is milling on a vertical milling machine. This processing method has low work efficiency, heavy workload, and the accuracy cannot be effectively guaranteed. and other defects. [0003] Patent No. 201310742174.0 (Application Publication No.: CN103737249A) discloses a method for processing ball sockets ...
