Abstract
The main purpose of this paper is to design a large numerical control sleeve rotary tailstock. Large numerical control sleeve rotary tailstock has the function of rotating the core shaft with the workpiece, the pressure gauge shows pressure, and the gear shifting gear which is changed manually. This paper designs and introduces the general working mode of the tail seat, the installation process of the gear shift gear shift, and the analysis and the strength and stability of the rear seat. Ordinary cylindrical worm drive bearing capacity calculation including the worm drive force analysis, the worm gear tooth surface contact fatigue strength calculation, the worm gear tooth root bending fatigue strength calculation, the calculation of the rigidity for the worm and worm drive the accuracy grade of choice. The strength calculation of the bevel gear transmission includes the force analysis of the gear teeth, the calculation of the fatigue strength of the tooth root and the fatigue strength of the tooth surface. The calculation of the shaft includes the strength of the shaft and the calculation of the rigidity of the shaft. Analyzing design process and making summary and improvement. According to the design scheme, the general assembly drawing and some main parts drawings are drawn by CAD, and the tail-seat structure is drawn with Solidworks software.
