Arc dresser for dressing grinding wheels of groove grinders for deep-groove balls

Abstract

The invention discloses an arc dresser for dressing grinding wheels of groove grinders for deep-groove balls. The particular implementation scheme includes that a driving shaft of a single-phase speed regulating motor (1) is connected with a bearing (3) by a coupler (2), an eccentric gear (4) is connected to the lower end of the bearing (3) and provided with an eccentric seat (41), the left side of the eccentric seat (41) is connected with a fixing pat (42), the lower portion of the fixing part (42) is connected with an adjusting part (43), the right end of the adjusting part (43) is connected with an eccentric part (44), the eccentric part (44) is connected with a grinding head (45) by a transmission oscillating plate (46), the grinding head (45) contacts with a grinding wheel (5), and the single-phase speed regulating motor (1) drives the transmission oscillating plate (46) to rotate in a reciprocating manner by the aid of shaft connection. The arc dresser has the advantages that adjustment is convenient and speedy when the arc dresser is used for trimming the grinding wheel, retardation and stop are avoided during rotation, forming profile of the grinding wheel is excellent, and roughness is low. In addition, the arc dresser is favorable for guaranteeing the quality of products, production efficiency is greatly improved, and production cost is lowered.

Description

technical field [0001] The invention relates to a grinding processing equipment, in particular to an arc corrector for correcting a grinding wheel of a deep groove ball groove grinder. Background technique [0002] The grinding machine is an important equipment in the process of bearing ring processing. The grinding accuracy of the deep groove ball groove directly affects the quality of the bearing. The direct factor of the poor groove grinding is that the grinding wheel corrected by the arc corrector is not good. Due to the hydraulic oscillating oil cylinder corrector used in the original machine tool, the pendulum plate and the cylinder body are seriously worn out after a long time of use, and the precision of the dressing wheel is lost, the size is seriously unstable, and the roughness is not good, which greatly affects the production. Moreover, the original parts are no longer produced, maintenance is quite difficult, and the machine tool is facing scrapping. Must be re...
