External cylindrical superfinishing machine for machining bearing ring

Abstract

The invention provides an external cylindrical superfinishing machine for machining a bearing ring, and belongs to the technical field of bearing machining. The external cylindrical superfinishing machine for machining the bearing ring comprises a machine body and two parallel guide rollers, wherein the two guide rollers are respectively driven by two motors fixed on the machine body; the rotation directions of the two guide rollers are the same; two vertical guide pillars are arranged on the machine body; a guide seat sleeves each guide pillar and slides along the guide pillar in the up-down direction; the inside of each guide seat is in threaded connection with a lead screw; a lifting motor which drives the lead screws to rotate is fixed in the machine body; a plurality of polishing cylinders which are arranged side by side are fixed on each guide seat; an oilstone which is used for polishing the bearing ring is fixed at an end of a push rod of each polishing cylinder; the oilstones are positioned above the guide pillars; an elongated feeding guide track and an elongated discharging guide track which are used for conveying the bearing ring are respectively arranged at two ends of the machine body; and the feeding guide track and the discharging guide track are respectively positioned at two ends of the guide pillars. By the external cylindrical superfinishing machine for machining the bearing ring, the bearing ring can be polished continuously. The external cylindrical superfinishing machine for machining the bearing ring has the characteristics of high machining efficiency and wide application range.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and relates to an outer circle superfinishing machine for processing bearing rings. Background technique [0002] With the continuous development of the machinery industry, the precision requirements for bearing products are also getting higher and higher. The size and surface finish of the bearing outer ring will affect the positioning accuracy of the bearing and the rotation stability of the bearing, so it is very important to improve the dimensional accuracy and surface finish. [0003] In the prior art, the grinding process of the bearing is a single process, such as the Chinese utility model patent application (application number: 200320105331.9) discloses a bearing grinding machine tool, including the bed, the head and the end of the bed: it is characterized in that: A, The head of the bed includes a spindle gearbox and an electromagnetic sucker; the spindle gearbox is set on a ...
