Embodiment

[0022] Embodiment: According to the raceway shape and technical requirements of the bearing, choose the oilstone with corresponding particle size and hardness, and put it into the superfinishing component; according to the specifications and models of different superfinishing products, select the corresponding online equipment and the corresponding workpiece Tooling, set system program. The running trajectory of the superfine device is controlled online through the system. The superfinisher can realize the superfinishing of any shape of the raceway, because of its own flexibility, it can be mounted on any CNC machine tool, the horizontal slide rail and the horizontal carriage control the Z-axis direction feed, the longitudinal slide rail and the longitudinal slide The block controls the X-axis feed, which is realized by the synchronous cross-feed of the X-axis and Z-axis. When superfinishing the outer raceway of the superfinished workpiece, it is only necessary to reverse the ...

Abstract

The invention discloses a bearing raceway superfinishing device, and relates to the technical field of bearing superfinishing. The bearing raceway superfinishing device comprises a machine tool body, a headstock is arranged on one side of the machine tool body, a tool clamp is arranged on the headstock, a workpiece is arranged in the tool clamp, a transverse sliding rail is arranged on the machine tool body, and a transverse sliding frame is arranged on the transverse sliding rail. The transverse sliding frame is provided with a superfine component through a longitudinal sliding component. The bearing raceway superfinishing device can completely cover any raceway shape, such as a conical raceway or an eccentric R raceway, can superfinish an outer raceway and an inner raceway of a bearing product, can be connected with any numerical control system machine tool for use, the bearing raceway superfinishing device can be used on a small numerical control machine tool, such as CJK6120, can further be used on a two-meter vertical lathe, is not restricted by specifications and models of processed products, realizes superfinishing process processing, has high maneuverability, is convenient and flexible to mount and dismount, and can cover superfinishing work of bearing raceways with more than 90% of specifications.

Description

technical field [0001] The invention relates to the technical field of bearing superfinishing, in particular to a bearing raceway superfinishing device. Background technique [0002] Bearing products have certain standards for the roughness of the raceway, and the normal raceway grinding process can only reach the roughness of Ra0.4. In order to obtain better surface roughness, ultra-finishing processing is required. [0003] Superfinishing refers to a process in which the workpiece rotates at a certain speed under good lubrication conditions, and at the same time, a fine-grained grindstone is pressed against the workpiece processing surface with a certain pressure, and a reciprocating vibration is performed perpendicular to the rotation direction of the workpiece. method. [0004] The design and use of the superfinisher can not only meet the requirements of the traditional superfinishing process, but also solve the bottleneck problem of superfinishing caused by the large ...
