Integrated grinding/turning mechanism of grinding lathe for ball valve bodies

Abstract

The invention discloses an integrated grinding/turning mechanism of a grinding lathe for ball valve bodies, which comprises a lathe base (1), a ball-clamping device (51), a ball-jacking device (52) and a grinding-disc rotating control device (53), wherein the lathe base, the opposite surface of the grinding-disc rotating control device and the side edge of the ball-clamping device are respectively provided with a turning device (50); and the turning device is composed of a ball-turning saddle, a ball-turning sliding plate, a turning head assembly, a sliding-plate longitudinal movement control assembly and a saddle horizontal movement control assembly. By using the integrated grinding/turning mechanism disclosed by the invention, the head part of a machined part is clamped by the ball-clamping device, the tail part of the machined part is jacked by the ball-jacking device, the surface of the machined part is ground by the grinding-disc rotating control device, and the surface of the machined part is turned on a same machine by the turning device, thereby eliminating the processing errors caused by respectively carrying out grinding and turning on different machines, improving the surface grinding machining precision and quality of a workpiece (in particular to a ball valve body), and improving the operating efficiency.

Description

1. Technical field [0001] The invention relates to a mechanical processing equipment, in particular to a turning and grinding machine. 2. Background technology [0002] Grinders and lathes are equipment for grinding and turning mechanical products respectively. Generally speaking, if the body surface of a symmetrical ball valve needs to be ground and turned, it needs to be processed by two different equipments of grinding machine and lathe in turn. It is inevitable that there will be processing errors, which will affect the processing accuracy and quality of the ball valve body. It is also less efficient. 3. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a turning-grinding integrated mechanism of a ball valve body turning and grinding machine that can realize grinding and turning on the valve body surface of a symmetrical ball valve on the same machine platform. [0004] The purpose of t...
