Ultra-precision grinding machine for ball track

Abstract

The invention discloses an ultra-precision grinding machine for a ball track. The grinding machine comprises a base, a camshaft, an emptying swing arm and a material receiving swing arm, wherein feeding components consisting of material hanging rods, feeding guide sleeves, emptying mechanisms, mechanical hands, blanking frames and bearing brackets are arranged on the base; emptying mechanisms are fixed on an emptying shaft; the mechanical hands are fixed on a material receiving shaft; two sides of the mechanical hands are provided with rolling rod mechanisms; grinding heads which swing in a reciprocating mode are arranged above the mechanical hands; ejector rod tools are arranged below the grinding heads; radial cams, a material receiving surface cam and an emptying surface cam are arranged on the camshaft; the ejector rod tools are driven by the radial cams to vertically move; the material receiving surface cam makes the material receiving shaft move transversely through the material receiving swing arm; and the emptying surface cam makes the emptying shaft move transversely through the emptying swing arm. Due to the structure, the ball track can be fully automatically machined, rough ultra-precision machining and finish ultra-precision machining can be performed on the same machine tool, and the quality and machining efficiency of the product are improved; meanwhile, the grinding machine is simple and compact in structure and convenient to operate, and the protection safety is improved.

Description

(1) Technical field [0001] The invention relates to a bearing raceway superfine grinding machine. (2) Background technology [0002] The bearing raceway is the space between the inner sleeve of the bearing and the outer sleeve of the bearing to accommodate the balls. It is the working surface that bears the load when the bearing is working. The quality of the surface of the bearing raceway directly affects the working performance of the bearing. Therefore, the roughness of the bearing raceway surface , roundness, etc. are the key to processing. [0003] Use a kind of manual superfinishing machine to process bearing raceway at present, and it is generally provided with a manual station, then carries workpiece on the station by hand and grinds. This kind of manual equipment has some obvious shortcomings. First, it is a problem of efficiency. Manual equipment needs manual loading and unloading, which takes a lot of time; Slow, low efficiency, and the two processes of rough su...

Problems solved by technology

This kind of manual equipment has some obvious shortcomings. First, it is a problem of efficiency. Manual equipment needs manual loading and unloading, which takes a lot of time; Slow, low efficiency, and the two processes of rough superfinishing and fine superfinishing need to be processed separately by two devices, which is very inconvenient. Moreover, the bearing raceway of manual superfinishing is relatively rough, resulting in low quality. Finally, manual control The ultra-fine grinding machine has no external protection, which is not safe enough
