Compound grinding machine

Abstract

The invention discloses a compound grinding machine. The compound grinding machine comprises a machine tool body, a working head assembly, an inner-hole grinding assembly and a top-circle grinding assembly; the working head assembly, the inner-hole grinding assembly and the top-circle grinding assembly are all mounted on the top of the machine tool body, and the inner-hole grinding assembly and the top-circle grinding assembly are located on the same side of the working head assembly; the working head assembly comprises a sliding assembly, a first motor, a second motor, a working head body, a working head spindle and a three-jaw chuck; the working head body is fixed at the output end of the first motor; the first motor is in sliding fit with the machine tool body through the sliding assembly; the working head spindle is pivoted to the working head body; the three-jaw chuck is fixed at one end of the working head spindle and close to the inner-hole grinding assembly and the top-circle grinding assembly; the second motor is fixed on the working head body and in driving connection with the working head spindle. The compound grinding machine is capable of completing the grinding of surfaces of a plurality of types through once clamping, and is high in machining efficiency and machining accuracy.

Description

technical field [0001] The invention relates to a compound grinding machine. Background technique [0002] At present, among the known methods of grinding workpieces, most of them need to process the inner hole and the outer surface of the workpiece through different grinding machine sub-processes, requiring manual secondary clamping, and very few parts can simultaneously perform internal and external grinding of the parts. Circular processing, but these models that can process both internal and external circles still need manual secondary clamping when processing parts with taper, semicircle and irregular circles, which cannot be completed at one time, and the processing efficiency is low. Clamping is easy to cause machining errors, which in turn makes the machining accuracy of parts low. [0003] Existing grinding equipment can only grind: outer circle, inner hole, end face, outer tapered surface, inner tapered hole. Contents of the invention [0004] In order to overc...
