As a commonly used shaft product in mechanical transmission, the application of spline shaft can be said to be very extensive. It is indispensable for automobiles, machine tools, and agricultural machinery, and it is even needed on airplanes. The processing order of its surface has a lot to do with the choice of positioning datum. Seeing this, many of my friends are puzzled, how to determine its positioning datum?
Because the structure and characteristics of the spline shaft itself determine that the accuracy of the spindle surface position must be high, and the axis is an ideal processing method. In order to find the positioning reference of the spline shaft, we can do the following What time does it work.
- When designing, it is necessary to ensure that the benchmarks of design, transformation and process extremes are unified.
- The number of clamping times should be reduced as much as possible. After positioning and clamping as much as possible, the complete surface to be processed can be processed.
- Try to avoid the use of manual adjustment processing methods that occupy the machine, so as to give full play to the efficiency and energy efficiency of the machine tool. In order to ensure the accuracy of processing, the center hole design given to you should be consistent with the positioning datum.
Generally speaking, the spline shaft does not need to have too high end face and radial runout requirements for the mating surface and the shaft shoulder facing the reference axis. Therefore, three-jaw automatic centering can be used when clamping and positioning. Way to proceed.
The processing of spline shafts has certain steps and technological processes, which require the use of a lot of professional equipment and technology. Only the products produced by formal manufacturers can meet industry standards, and the quality of the spline shafts produced can also pass the barrier. And meet the actual application requirements.
