Short shaft part milling machining method

Abstract

The invention relates to a short shaft part milling machining method which is characterized in that a multi-station four-shaft rotary milling machining pneumatic tool is adopted to perform operation and is installed on four shafts of a CNC machine tool, the free end of a cylinder is retracted, and a pull rod drives a pressure plate to ascend, so that a part, to be processed, of a valve element isplaced in each V-shaped groove of a V-shaped block assembly, self-centering is performed on the parts depending on the corresponding V-shaped grooves, then the free end of the cylinder extends out, the pull rod drives the pressure plate to descend, the pressure plate compresses the parts, and the positioning of the parts is completed. Therefore, loading and unloading of the parts can be controlledthrough a pneumatic switch, and milling machining is started; and through rotation of a four-shaft central shaft, the four-shaft central shaft needs to be rotated by plus / minus 90 degrees only whilemilling machining is performed on the two end surfaces of each part. The short shaft part milling machining method provided by the invention is convenient to operate, can be suitable for workpieces with different outside diameters, needs clamping at one time only when milling machining needs to be performed on all of an excircle and the two end surfaces of each part and has the advantages of improving the processing efficiency and processing precision.

Description

technical field [0001] The invention relates to a milling method for short-axis parts. Background technique [0002] The traditional milling of the end face groove of the short-axis part relies on the three-jaw clamping end milling. Whenever the part needs to be milled on the outer circle and both ends of the part, it is necessary to repeat the clamping of the part three times to complete the milling process, but the repeated clamping of the part affects the part. The processing efficiency, the precision of milling and the turnover of parts. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages, provide a milling method for short-axis parts that is easy to operate, and can be clamped once when the parts need to be milled on both the outer circle and both ends of the parts, so as to improve the processing efficiency and processing accuracy. [0004] The purpose of the present invention is achieved like this...
