Abstract

The main characteristics of a new automatic device for the fixation of objects in executive links of technological equipment, which determine its suitability for use, are considered. The device is based on a new structure that ensures its self-braking after the process of object fixation and increases the reliability of holding the objects, which is especially important in safety-critical applications. The proposed structure can be implemented for use in various types of executive links of technological equipment, and in the paper, it is considered the most complex application of the device—as part of a spindle assembly. For the proposed design, the method of calculating the main parameters of this type of mechanism is presented. Based on the results of the research, analytical and graphical dependencies have been obtained describing the change of the clamping force from 45 to 15 kN when increasing the spindle speed up to 10000 rpm, and the dependence of the clamping force on the torque at the input link. Based on the results of the research, a preliminary conclusion has also been drawn regarding the possibility of using electromechanical clamping mechanisms of the proposed type as a part of spindle units of machine tools, also because the rotor diameter of the mechanism is within 100 mm and the stator is within 200 mm.
