Recently, many industries pursue the goal of automatic high-speed assembly and manufacturing. So how to meet the requirement of high-precision and high-speed automatic assembly equipment is an important issue. In automatic assembly equipment, the high-speed indexing devices have been widely used because of their features of high precision, no backlash, and compactness. With increasing operating speeds, the problems of shortage of motor power, poor indexing accuracy, vibration, and noise shall be solved. The torque compensation mechanism that is to be developed here is applied to keep motors operating at constant speeds by compensating the required torque. In previous researches, the researchers all devote to study torque compensation based on synchronous time chart. In this paper, it is aimed at compensation of the time control chart according the point of view of energy and the system model is built to simulate dynamic response of the system. Through the results of simulation and experiment, we will discover the relations between the compensation time chart and parameters about the high-speed indexing devices. It is expected to improve the precision of indexing devices according to those effective compensation time control charts.

This diploma thesis deals with projection and general design of rotary indexing table for dedicated machine tools. The major attention is given to substitution of hydraulic drive table by table driven by servomotor, namely double axis its positions in vertical and horizontal directions. The total configuration of rotary table is solved as a construction kit, user can used any servomotor and additive gearbox. The work is concentrated to the optimization of table construction for this new designed conception. The positioning and fixing of table plate is solved by couple of Hirth couplings with central hydraulic motor. The computational part of work includes calculations of dynamic of rotary motion of the table and hydraulic system. All important screw connection, gear wheels and Hirth couplings were verified by calculations. Also working lifetime of bearings and strength deformation of major constructional sections of rotary table verification were controlled. Inherent part of work is security analysis, economics analysis, patent search and analysis of construction identity. Presented work contains three-dimensional model, drawing documentation of both variants of configurations and production drawing of major section parts of rotary table.
