Problems solved by technology

[0002] In the surface processing of the existing step shaft, one end of the workpiece is generally clamped on the three-jaw chuck, and the other end is positioned by the tip of the tailstock. When the workpiece is rotated, the part clamped by the three-jaw chuck cannot be processed. , after the rest of the processing is completed, the workpiece needs to be disassembled for reverse clamping and positioning, which increases the processing process and prolongs the processing time, and the U-turn processing affects the accuracy of the workpiece processing

Embodiment Construction

[0018] Such as figure 1 , figure 2 , image 3 As shown, the method for one-time processing of the outer surface of the stepped shaft of the present invention is characterized in that it comprises the following steps:

[0019] 1) Process a process hole at the non-center of the end surface of the largest outer circle of the step shaft;

[0020] 2) Clamp a dial with a top on the three-jaw chuck of the lathe, push the left end of the step shaft on the top of the dial, and push the right end on the top of the tailstock of the lathe;

[0021] 3) Install a fixed pin on the dial, insert one end of the fixed pin into the process hole of the step shaft, and fix the other end on the dial;

[0022] 4) Start the lathe, the fixed pin drives the workpiece to rotate, and use the turning tool to process the step shaft once.

[0023] The dial is provided with a bar-shaped groove, and the fixed pin is arranged in the bar-shaped groove and can slide in the bar-shaped groove.

[0024] The to...

Abstract

The invention discloses a method for machining a step shaft surface and with double-top positioning and once machining the step shaft surface, and belongs to the field of machining methods. Accordingto the method for machining the step shaft surface, through a double-top clamping workpiece, a fixing pin is connected with a technology hole in the workpiece surface, the workpiece is guaranteed to rotate, the workpiece surface machining can be completed once. Machining efficiency is improved, and the machining time is shortened. The method can be widely applied to the field of machining.

Description

technical field [0001] The invention discloses a method for processing the outer surface of a stepped shaft at one time, and belongs to the technical field of mechanical processing methods. Background technique [0002] In the surface processing of the existing step shaft, one end of the workpiece is generally clamped on the three-jaw chuck, and the other end is positioned by the tip of the tailstock. When the workpiece is rotated, the part clamped by the three-jaw chuck cannot be processed. , after the rest of the processing is completed, the workpiece needs to be disassembled for reverse clamping and positioning, which increases the processing process and prolongs the processing time, and the U-turn processing affects the accuracy of the workpiece processing. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, and provides a method for positioning the two tops and processing the outer surface of the stepped shaft at one time. ...
