Electromagnetic and electric push rod mixed-loading tool rest reliability testbed

Abstract

The invention discloses a reliability testing device of a machine tool power tool rest and particularly relates to an electromagnetic and electric push rod mixed-loading tool rest reliability testbed. The problem that the working condition of the tool rest on an oblique bed body cannot be simulated and three-directional tool rest loading cannot be simultaneously conducted on the tool rest in the prior art is solved. The electromagnetic and electric push rod mixed-loading tool rest reliability testbed consists of a tool rest supporting part, a cutting force loading part, a tool rod part and a torque loading part. The tool rest supporting part comprises an X-direction moving unit and a Y-direction moving unit. The tool rod part is fixed to the power tool rest. The power tool rest is fixed to the X-direction moving unit. The cutting force loading part is arranged on one side of the power tool rest. The cutting force loading part comprises X-direction and Y-direction electromagnetic loading units and a Z-direction electric push rod loading unit. A dynamometer in the torque loading part is connected with a power output shaft of the power tool rest. The electromagnetic and electric push rod mixed-loading tool rest reliability testbed is closer to an actual usage state of the tool rest and has the advantages of being high in universality, easy to adjust, simple in structure and small in size.

Description

technical field [0001] The invention relates to a reliability test device for machine tool power tool holders. More precisely, the invention patent relates to a dynamic and static loading of machine tool power servo tool holders through electromagnetic and electric push rods, and then through a dynamometer Realize the reliability test bench of the dynamic tool holder for torque loading. Background technique [0002] CNC lathe is a high-precision, high-efficiency automatic machine tool. Equipped with a multi-station power tool holder, the lathe has a wide range of processing performance, and can realize compound processing such as turning, milling, and drilling, which greatly improves processing efficiency. However, due to the complex structure of the dynamic tool post, there are many types of faults, and its performance and reliability directly affect the operating efficiency of the host machine and the quality of processed products. According to statistics, the maintenanc...
