Numerical control piston inner diameter processor

Abstract

The invention relates to a numerical control piston inner diameter processor, comprising a machine tool body, a fixed main shaft, a rotating main shaft and feeding mechanisms, wherein the fixed main shaft and the rotating main shaft are arranged on the feeding mechanisms; the feeding mechanism of the fixed main shaft is connected on the machine tool body longitudinally and movably; the fixed mainshaft is provided with a fixture for piston workpieces; the feeding mechanism of the rotating main shaft is connected on the machine tool body laterally and movably; the rotating main shaft is provided with a cutter fixing structure and a pneumatic pre-tightening mechanism and connected with a power transmission mechanism; the feeding mechanism is a ball screw transmission mechanism of a two-spindle servo control system; and the cutter fixing structure of the rotating main shaft is fixed with a cutter which can process the central dead head, inner diameter, end face and chamfer of the piston simultaneously. By adopting the technical scheme, piston workpieces and a cutting tool only need one time of clamping, the central dead head, inner diameter, end face and chamfer of the piston can be processed one time through the numerical control of the two-spindle servo control system, thus improving the processing precision of the piston workpieces, and the inner diameter processor has convenient operation and debuging and high machining efficiency.

Description

technical field [0001] The invention relates to a metal processing machine tool, in particular to a numerically controlled piston inner diameter processing machine. Background technique [0002] Existing piston processing machine tools are generally single-process machine tools. The main shaft adopts low-precision and low-speed main shaft with hydraulic automatic feed, and the clamping of the processed workpiece adopts special clamps driven by hydraulic pressure. The riser, inner diameter, end face and chamfer have poor machining accuracy and low machining efficiency. Contents of the invention [0003] The object of the present invention is to provide a numerical control piston inner diameter processing machine which can simultaneously process the center riser, inner diameter, end face and chamfer of the piston and improve the machining accuracy. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: the piston inner dia...
