Embodiment Construction
[0025] Such as Figure 1-Figure 5 As shown, the tooling used in the present invention is disc-shaped, and consists of two pieces, which are divided into fixed plate one 1 and fixed plate two 2, and fixed plate one 1 and fixed plate two 2 are equipped with positioning notches, and fixed plate one is upper. The diameter of the positioning slit on the fixed plate is 110-0.05mm, and the diameter of the locating slit on the fixed plate 2 is 180+0.035mm. The fixed plate 1 and the fixed plate 2 are respectively two sets of keyway positioning; 1. Fixed plate 2 2 is respectively set on the outer circles of the left and right shaft ends of the upper roller shaft 3. The installation method of fixed plate 1, fixed plate 2 2 and the outer circle of the shaft ends is a clearance fit installation. The lower end and the upper end of fixing one 1, fixing two 2 are respectively fixing one looking for front 4 and fixing two looking for front 5.

The invention discloses a machining method of shaft part key grooves with multiple specifications and multiple angles. The machining method comprises the steps that tools are installed, and the tools are installed on a workpiece and adjusted; upper roll shafts are erected through V-shaped iron at the two ends, and a dial indicator is pulled by 90 degrees in the two directions for calibration; a stator disk I is installed, a 36P9 key groove is machined on the center line, the upper roll shafts are rotated, and a 36P9 key groove with the included angle of 120 degrees in the other direction is machined; a stator disk II is adjusted and installed accurately, 56P9 key grooves on other two center lines are machined according to the previous steps. According to the machining method of the shaft part key grooves with the multiple specifications and the multiple angles, positioning is accurate, machining precision is high, the production efficiency is improved, the machining cost is reduced, the interchangeability of machined products is good, and the difficulty and cost of maintenance service are greatly reduced.
Description
technical field [0001] The invention relates to a processing method of key grooves, in particular to a processing method of multi-standard and multi-angle key grooves of shaft parts. Background technique [0002] The roll forging machine is mainly used for pre-forging of forgings, and can also be used for final forging. It can realize automatic production with manipulator or other automatic feeding device. The upper and lower roller shafts are the key components of the roll forging machine. This part has keyways with various specifications and sizes and multi-angle distribution on the circumference. In the traditional processing process, after the grinding process is completed, the fitter assembles the mating part and the upper roller shaft together, and makes the keyway processing position line according to the mating part number; the milling and boring machine is aligned according to the line, and the keyway is roughly and finely milled; Reassemble the upper roller shaft,...
