Processing device and processing method for spherical pit of piston of automobile air conditioner

Abstract

The invention discloses a processing device for a spherical pit of a piston of an automobile air conditioner, which comprises a milling machine rack. A spindle box is arranged on the rack; the front end of the spindle box is provided with a spindle; the front end of the spindle is provided with a workpiece clamping tool; the workpiece clamping tool comprises a workpiece connecting disk, a clamp body, a radial clamping device and an axial positioning device; the clamp body is connected with the workpiece connecting disk; the radial clamping device is arranged on the end face of the clamp body; the axial positioning device is vertical to the radial clamping device to be arranged on the end face of the clamp body; a tool transverse feeding device and a tool longitudinal feeding device arranged on a machine tool body; a milling mechanism is arranged on the tool transverse feeding device; a milling cutter is arranged on the milling mechanism; and the milling cutter is of an olive shape. The invention also discloses a processing method for the spherical pit of the piston of the automobile air conditioner. The accurate positioning and clamping of a workpiece can be implemented by the processing device. By the processing device and the processing method, not only are the surface quality and the geometric tolerance of a processed surface of the spherical pit improved, but also the processing efficiency is improved.

Description

Technical field [0001] The invention relates to a mechanical processing device and a processing method, and in particular to a processing device and a processing method of an automobile air-conditioning piston ball pit. Background technique [0002] At present, in the process of processing automobile air-conditioning piston ball pits, the surface quality of the ball pit surface processed by the existing processing device and processing method is not high, the geometric tolerance accuracy is not high, and the processing efficiency is low. The workpiece fixture is positioned Insufficient precision, insufficient clamping reliability, time-consuming and laborious installation of the workpiece.
