Abstract

The invention discloses a diamond pen microscale feed mechanism for bearing grinder interpolation and finishing. The diamond pen microscale feed mechanism comprises a diamond pen, a diamond pen rack, a fixed seat, a large gland, a connecting sleeve and a drive device, wherein the connecting sleeve comprises a connecting part and a lead part with a cylindrical surface; the connecting part is connected with the drive end of the driving device; the lead part is connected with the diamond pen rack; the large gland is sleeved outside the lead part; one end of the large gland is fixed on the fixed seat; a gap is formed between the other end of the large gland and the connecting part; a group of symmetric stepped holes are formed in the large gland; push rods are mounted in the stepped holes; the front end of each push rod is connected with the connecting sleeve through a bolt; and a pre-tightening component is arranged on the rear end of each push rod. The diamond pen microscale feed mechanism for bearing grinder interpolation and finishing has the advantages that the structure is simple and compact, parts are easy to manufacture, the design is convenient, the stroke can be simply controlled within a certain range, a pre-tightening force exists in the workable stroke, and the feed precision is higher.

Description

technical field [0001] The invention relates to the technical field of bearing grinding machines, in particular to a simple diamond pen micro-feeding mechanism used for interpolation and dressing of grinding wheels during the grinding process of bearing raceway convexity. Background technique [0002] In the crown grinding of the bearing raceway, sometimes it is necessary to trim the grinding wheel into the required convex shape, and then use the trimmed grinding wheel to grind the bearing ring to make the ring reach the required convex shape. When dressing grinding wheels, interpolation dressing with dual servos is sometimes used. Since the effective feed stroke in the direction of the diamond pen is generally only about 0.01mm, there are many forms of its stroke control on the market, such as ordinary steel guide rails, linear guide rails, spring sheets, etc. Their general disadvantages are complex structures, or difficult mechanical stroke control, or no pre-tightening f...
