Embodiment

[0023] A processing method suitable for stepped shafts of the present invention comprises the following steps:

[0024] A: Select a forging 45 steel, process the forging 45 steel into a bar of Φ35mm×250mm, and heat treat the bar;

[0025] B: Clamp the heat-treated bar, correct the clamped bar, and ensure that the bar is clamped;

[0026] C: Then rough turn the left and right end surfaces of the bar, turn the left end surface into a cylinder with a size of Φ33mm×60mm, and ensure that the right end surface has a length of 1mm, and then drill a center hole on the right end surface;

[0027] D: Withstand the center hole, rough out the outer circles with dimensions of Φ26mm×166±0.5mm, Φ23mm×155±0.5mm, and Φ21mm×29±0.5mm from the left end to the right end; Carry out semi-finishing rounds, and finish the outer circles with dimensions of Φ25.5±0.5mm×166mm, Φ22.5±0.5mm×88mm, Φ20.5±0.5mm×29mm in turn; Finish turning, followed by finish turning out the outer circles with dimensions of ...

Abstract

The invention discloses a processing method suitable for stepped shafts, which comprises the following steps: A: select a 45 steel forging, process the 45 steel forging into a bar, and heat-treat the bar; B: heat-treat the bar Clamp the clamped bar, correct the clamped bar, and ensure that the bar is clamped; C: Then rough turn the left and right end faces of the bar, turn the left end face into a cylinder, and ensure that the right end face remains There is a length of 1mm, and then drill a center hole on the right end face; D: Hold the center hole, and turn three sections of outer circles with different sizes from the left end to the right end face; Turning; E: Then, the three outer circles after finishing turning in step D are polished; the present invention solves the problems of too low rigidity of the existing stepped shaft and low machining accuracy.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method suitable for stepped shafts. Background technique [0002] Shaft, the mechanical part that supports the rotating part and rotates with it to transmit the motion, generally in the shape of a metal round rod, each section can have different diameters, and the parts that make the rotary motion in the machine are mounted on the shaft. According to the shape of the shaft, the shaft can be divided into two types: crankshaft and straight shaft; according to the bearing capacity of the shaft, it can be divided into: rotating shaft, mandrel and transmission shaft. Rotating shaft: It bears both bending moment and torque during work. It is the most common shaft in machinery, such as the shaft in various reducers, etc.; mandrel: it is used to support rotating parts and only bears bending moment without transmitting torque. Some mandrels Rotation, such as the shaft of...
