Abstract

The invention belongs to the technical field of mechanical equipment reliability testing, and particularly relates to a motorized spindle reliability test bed based on twin trawling loading. The testbed comprises spindle installing parts, a mechanical loading part, a status monitoring part and a circuit control part. According to the spindle installing parts, due to V-shaped structure positioning, the spindle installing part A and B and horizontal iron are matched and adjusted, and positioning and centering between motorized spindles of different outer diameters can be achieved. According tothe mechanical loading part, a main loading block and a slave loading block transmit torque through conical surface contact, additional radial force and additional axial force are generated at the same time, and the actual tool cutting working condition can be simulated. According to the status monitoring part, the status of the motorized spindles is monitored by installing sensors on two supports. According to the circuit control part, a direct current bus is adopted between a frequency converter A and a frequency converter B for feeding back current to achieve the energy recycling purpose. The problems that an existing motorized spindle reliability test bed is poor in reliability, low in testing efficiency, high in testing cost and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of mechanical equipment, in particular to an electric spindle reliability testing platform based on dragging. Background technique [0002] As the industrial mother machine of the machinery manufacturing industry, CNC machine tools are an important cornerstone of modern development. Compared with imported CNC machine tools, the reliability level of domestic high-end CNC machine tools is relatively low, resulting in a low market share of domestic high-end CNC machine tools, which restricts the development of domestic CNC machine tool industry. As one of the key functional components of the CNC machine tool, the electric spindle's reliability level directly affects the reliability of the CNC machine tool. [0003] In the actual cutting process, the electric spindle is mainly subjected to three dynamic forces: radial force, axial force and torque, and the changes of the three dynamic for...
