Elastic rolling floating support for centerless grinding of outer circle of annular part

Abstract

The invention discloses an elastic rolling floating support for centerless grinding of an outer circle of an annular part. The elastic rolling floating support comprises elastic supporting bodies, supporting sleeves, compressed springs, transition blocks and a supporting seat; the elastic supporting bodies press the supporting sleeves through T-shaped bolts to be connected to the transition blocks, the transition blocks are connected and fixed on the supporting seat of a machine tool shell, one end of each elastic supporting body is provided with a plurality of pairs of supporting heads, alloyballs are correspondingly arranged at the end parts of the supporting heads, and the other ends of the elastic supporting bodies are fixed on the supporting seat; and a coil shell is arranged on theinner side of the supporting seat, a coil is arranged in the coil shell, a sealing body is arranged outside the coil, a magnetic pole is arranged on the outer side of the coil shell, and the magneticpole is fixed on a workpiece shaft. According to the elastic rolling floating support, non-supporting mark grinding is achieved through rolling friction between supporting points and the surface of the workpiece, and follow-up treating matters caused by support marks and even burn are greatly reduced, the influence of the elastic deformation of the workpiece on the grinding efficiency and the quality is reduced, the stress of the elastic supporting points tends to be consistent, and all the points are always in effective supporting states.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for cylindrical grinding of workpieces, in particular to an elastic rolling floating support for centerless grinding of circular parts. Background technique [0002] The support of the workpiece in the centerless grinding of the outer circle of the existing ring parts mainly includes rigid supports such as Image 6 As shown, the floating support is as Figure 7 As shown, because the existing rigid support and floating support are in sliding contact with the processing surface of the workpiece, it is inevitable to produce support marks or even burns on the surface of the workpiece, and because the fulcrum wears quickly, the actual support position gradually changes during processing, which affects the processed products. Consistency of quality; secondly, there are few support points, and the elastic deformation of the workpiece under the action of grinding force greatly affects the grindi...

[0002] The support of the workpiece in the centerless grinding of the outer circle of the existing ring parts mainly includes rigid supports such as Image 6 As shown, the floating support is as Figure 7 As shown, because the existing rigid support and floating support are in sliding contact with the processing surface of the workpiece, it is inevitable to produce support marks or even burns on the surface of the workpiece, and because the fulcrum wears quickly, the actual support position gradually changes during processing, which affects the processed products. Consistency of quality; secondly, there are few support points, and the elastic deformation of the workpiece under the action of grinding force greatly affects the grinding accuracy level and production efficiency; moreover, because the alloy rods of the support points are mostly welded, the fulcrum is replaced after wear Or it is difficult to adjust; with the development of product technology level, the inadequacies and contradictions of the above-mentioned various supports are highlighted, and it is difficult to adapt to the requirements of high-end product grinding supports
