Electromagnetic centerless fixture for conical ring machining and positioning and adjusting tool technique thereof

Abstract

The invention discloses a shoe-type centerless fixture for processing a cone ring and its positioning adjustment tooling technology. The support block is movable and set in a machine clamp mode, so that the support surface of the support block can be adjusted radially relative to the workpiece installation area, so that the The crawler type centerless fixture for cone ring processing can process workpieces of various specifications and sizes, and the angle adjustment of the supporting surface of the supporting block can be adjusted clockwise or counterclockwise. Through the adjustment of the angle, the supporting surface can be fully aligned with the outer conical surface of the workpiece. fit, so as to reduce the adhesive wear of the outer cone surface between the support surface and the workpiece and cause the unqualified phenomenon of the workpiece. Further, before processing the workpiece, the positioning body is used to pre-adjust the centerless clamp for cone ring processing. The eccentric direction and eccentric distance between the workpiece of the specified size and the workpiece spindle on the fixture ensure the stability of the workpiece during the grinding process.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a shoe-type centerless clamp for processing a cone ring and a positioning adjustment tooling process thereof. Background technique [0002] In the internal grinding process of metal circular parts or bearing rings, crawler centerless fixtures (also known as electromagnetic centerless fixtures) are commonly used to clamp workpieces. This technology was first used in the 1940s by Barden Corporation of the United States. In order to improve the grinding precision of the bearings used for bomb sights, it has been promoted and improved in the bearing industry of various countries and has been used until now. The characteristics of the trackless centerless fixture are: the center of the workpiece does not coincide with the center of the main shaft, and the end surface magnetic attraction is used for clamping instead of rigid radial clamping, and its machining accuracy is ...
