Analysis of parts processing technology Heat treatment: improve the stability of the material through normalizing, reduce the deformation of the continuation sequence, cutting: correct the clamping; parts left and right, cutting, drilling, machining, slightly turning centering—including Sufficient margins should be left on the top of the tooth and the end face, and the roughness of the surface should meet the requirements of I: art and the inner grid and spline hole of the car did not meet the requirements of the drawing. Insert the spline: Clamp the left end. Be careful of the end face and the end face beating. The high point is in the same direction as the 4 coordinates. Clamp it firmly. Use the inner spline electric paper to roll up and correct. : Carburizing, and quenching to paper requirements.
After heat treatment, precision machining manufacturers can use the V positioning method to ensure the mutual position between the internal spline, the two bearings and the wheel, and the positioning of the internal spline and end face within a degree of 1. The internal spline is a progressive angle with a forced angle of 20 Open-line flower sowing when the centering of the curve is set to 5 positions of the crucible, the spline mandrel moves on, the process economy is good, the general installation rigidity is low, the stability is poor, and it is difficult to control the positional accuracy between the surfaces of the parts The upper part is positioned with a hole at 60°, and the two cars in the internal control are out of 60°. Cone hole, with 60 extrapolated core pomelo Anji zero payment, tighten the front flash firmly. The 60° push hole not only has the requirement of a 3.5 mm ridge, but also needs to match the contact surface with the external taper mandrel, so the process economy of taper hole positioning is more economical. Universal mill: Install the four-claw chuck, clamp the right end, correct the outer hole on the right side and the inner hole on the left side, and put the two bearings on the paper; gears: 4000 mandrels, install it, and adjust the tooth position.
