Problems solved by technology

[0003] 1. After the spline is pulled, the runout of the large end face of the connecting flange is unqualified, which affects the runout of the small end face of the connecting flange.
[0004] 2. The axial reference of the product cannot be guaranteed to be consistent, and the precision of the processed connecting flange is low
However, tool setting is required before each connecting flange is turned, resulting in low work efficiency

specific Embodiment 1

[0043] see Figure 3 to Figure 7 As shown, a processing equipment for rear axle connection flanges includes a lathe and a broaching machine for pulling splines. The broaching machine is provided with a positioning block 1 for positioning the small end face of the connecting flange blank 3. The positioning block 1 Instead of the positioning block on the existing broaching machine that is positioned on the large end face of the connecting flange blank 3, the positioning block 1 on the small end face of the broaching machine is provided with a positioning groove 1-1 for positioning the small end face of the connecting flange blank 3. The broach and other structures of the broaching machine are the same as those of the existing broaching machine, so this embodiment is omitted here.

[0044]The main shaft of the lathe is provided with a spline expansion fixture 2, and the spline expansion fixture 2 is used to cooperate with the internal spline of the connecting flange blank 3 to cl...

Abstract

The invention discloses a processing technology and equipment for a rear axle connecting flange. The technology comprises the following steps: a connecting flange blank is obtained by forging, electrophoretic paint processing is carried out on the connecting flange blank, and then the connecting flange blank is processed by the following steps of: 1, processing a small end surface of the connecting flange blank; 2, adopting a broaching machine, arranging a small end surface positioning block on the broaching machine, mounting the small end surface of the connecting flange blank processed in the step 1 on the small end surface positioning block of the broaching machine as a positioning surface, carrying out spline broaching on an inner hole of the connecting flange blank through a broaching tool of the broaching machine, and processing an internal spline of the connecting flange blank; and 3, adopting a lathe, taking the small end surface of the connecting flange blank processed in the step 2 as the positioning surface, clamping the connecting flange blank on the lathe, and processing a large end surface and a large end surface spigot of the connecting flange blank through a lathe tool of the lathe. According to the processing technology and equipment, the processing accuracy and the working efficiency of the connecting flange are improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing technology and equipment for connecting flanges of rear axles. Background technique [0002] The connecting flange of the rear axle is used to connect the drive shaft and the gear of the main reducer. Since both the drive shaft and the gear of the final drive are in high-speed operating conditions, in order to ensure the reliability of the connection, the precision of the connecting flange is required to be high. The existing rear axle connecting flanges are usually made of forgings. In order to protect the connecting flanges, each connecting flange needs to be treated with electrophoretic paint before turning the end face and pulling the splines. The manufacturing and processing methods of the end face and the drawing spline are as follows, see figure 1 Shown: First use the large end face of the connecting flange for positioning, use the broaching machine to pu...
