Oilstone rocking mechanism for ultra-precise grinding process of bearing outer ring channel

Abstract

The invention discloses an oilstone rocking mechanism for an ultra-precise grinding process of a bearing outer ring channel, and relates to the technical field of bearing processing. The oilstone rocking mechanism comprises a pull rod, a swing rod, a supporting base and a motor; a rotating block is mounted at one end of the output shaft of the motor; the rotating block and the output shaft of themotor are arranged coaxially; one end of the pull rod is movably connected to an edge of the bottom of the rotating block; the other end of the pull rod is movably connected to a swing block; the rotating block, the pull rod and the swing block constitute an eccentric transmission mechanism; one end of the swing rod is connected with the swing block; the other end of the swing rod passes through the supporting base and used for mounting a grinding device; when the output shaft of the motor rotates, the pull rod moves back and forth and pushes the swing block to swing, and further drives the swing rod to swing along the shaft, therefore, the grinding device is driven to swing; a first spring is arranged on the swinging rod; one end of the first spring is connected to the swinging rod; and the other end of the first spring is fixed directly below the swinging rod. The oilstone rocking mechanism is relatively high in swing frequency, uniform in swing speed and stable in oilstone pressure,and can improve the qualification rate of products.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to an oilstone rocking mechanism used in the ultra-precision grinding process of the groove of the bearing outer ring. Background technique [0002] The ultra-precision grinding process of the bearing outer ring groove is usually carried out by using oil stone combined with the method of low-pressure and high-frequency vibration grinding of the rocking mechanism. The swing frequency of the oilstone swing head is not high, and can only reach 400~600 times per minute. Not only that, if the hydraulic pressure and air pressure are unstable, the swing speed of the swing mechanism will be uneven, and the pressure of the oilstone will be unstable. directly affect the quality of the product. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and to provide a whetstone rocking mechanism used in the u...
