Linear motor module with embedded guide rail

Abstract

The invention discloses a linear motor module with an embedded guide rail. The linear motor module comprises the guide rail and a sliding block. Grooves are formed in the inner surface of the sliding block and the two sides of the guide rail respectively, rolling body raceways made of carbon steel or stainless steel are embedded in the grooves, a return hole is formed in the sliding block, return end covers are fixedly installed at the left end and the right end of the sliding block, rotation grooves are formed in the return end covers, and the rolling body raceways, the return hole and the rotation grooves form a rolling circulation rotation channel. A rolling body made of stainless steel is mounted in the rolling circulation rotary channel; the return hole is positioned above the rolling body raceway; the guide rail is provided with a magnetic railing ruler or a grating ruler, and the sliding block is provided with a grating reading head; and a linear motor stator is installed on the guide rail, a linear motor rotor corresponding to the linear motor stator is arranged on the sliding block, and the motor rotor is communicated with a power source. The rolling body does not pass through the magnetic induction line range during rotation, it is guaranteed that the rolling body is not magnetized, and the smoothness of rotation of the rolling body is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of linear motion modules, in particular to a guide rail embedded linear motor module. Background technique [0002] The linear motor module is a transmission device that converts electrical energy directly into linear motion mechanical energy by expanding a closed magnetic field into an open magnetic field without any intermediate conversion mechanism. It is generally composed of guide rails, sliders, screw rods, aluminum alloy parts, etc., and the stators of dynamic and linear motors realize linear motion through the principle of non-contact magnetic induction. [0003] Now, due to the needs of working conditions, in addition to the more compact shape and structure of the linear motor module, the response and operating speed of the linear motor module are required to be higher, and the repeat positioning and position accuracy are also required. Therefore, The current linear motor module structure can no lo...
