Self-balancing rotation and swing mechanism for bearing channel superfinishing

Abstract

The invention provides a self-balancing rotation and swing mechanism for bearing channel superfinishing. The mechanism comprises a rocker arm, a swing generation amplitude adjusting mechanism, a swing self-balancing mechanism and a reset clearance elimination mechanism, a swing shaft is sleeved with the rocker arm, the rocker arm swings around the swing shaft, a balance structure is arranged at the upper end of the rocker arm, and the lower end of the rocker arm slides with the swing generation amplitude adjusting mechanism in a matched mode. The swing generation amplitude adjusting mechanism and the swing self-balancing mechanism are arranged in a dovetail groove of a circular seat disc at the upper end of the rotating shaft, the swing self-balancing mechanism comprises an adjusting body, an adjusting screw rod, a balancing body and the like, a pressing block is used for pressing, and the adjusting screw rod is twisted to adjust the mutual position relation between the adjusting body and the balancing body. An elastic body is arranged between a pendulum shaft seat and the rocker arm. Through the rocker arm symmetry balance structure and the swing self-balancing mechanism, the force transmission process is stable and reliable, and the problem of superfinishing adaptability of different types of bearing channels is solved through the swing generation amplitude adjusting mechanism. The reset clearance elimination mechanism ensures that the swing generation amplitude adjusting mechanism timely resets to eliminate the clearance. The rotating shaft and the circular seat disc are designed into a whole, transmission links are reduced, and occupied space is small.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and relates to a bearing channel ultra-precision self-balancing rotating and rocking mechanism. Background technique [0002] The superfinishing of the bearing ring groove is one of the key processes of the bearing ring finishing, and the superfinishing machine is the key equipment for realizing the superfinishing of the bearing ring. Reciprocating grinding on the surface of the bearing ring channel to achieve the forming process of the surface of the bearing ring channel, mainly to improve the surface roughness, waviness, geometric shape and other accuracy of the bearing ring channel, to ensure the assembly of the bearing ring and the ball The rotation accuracy reduces the vibration, noise and temperature rise of the bearing during high-speed rotation, and improves the service life and reliability of the bearing. In order to improve the precision of the raceway of the bearing ring, t...

Problems solved by technology

[0003] Aiming at the defects and technical problems existing in the processing process of the existing bearing ring channel superfinishing machine, a bearing channel superfine self-balancing rotary rocking mechanism is provided. Reduce; set up the amplitude modulation mechanism for swing generation, adjust the swing amplitude of the swing shaft, and solve the adaptability of different types of bearing ring channels for superfinishing; set up a swing self-balancing mechanism to solve the problem of unbalance generated when the swing generation amplitude modulation mechanism is adjusted; A reset and anti-backlash mechanism is installed between the swing generation amplitude modulation mechanism and the swing shaft. When the superfinishing of the bearing ring is adjusted or finished, the swing generation amplitude modulation mechanism is reset and the gap of the swing pair is eliminated in the whole process, reducing the commutation impact and avoiding vibration ripples; The design of the rotating shaft and the circular seat plate is integrated to reduce the transmission link and improve the stability and reliability of the transmission
