[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an indirect speed-changing device that assists the motor. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In automatic control systems, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. However, the servo motor needs to be connected to a screw module, and the screw module is mainly used for part rotation.

[0003] The prior art (patent number: CN209994232U) discloses a novel screw module, including a screw module, a linear motion motor and a rotary motor, wherein the linear motion motor is provided with a base, the base is provided with a rotatable rotary bracket, the screw module is fixed on the rotary bracket, a screw is provided in the screw module, the output shaft of the linear motion motor is connected to the screw, and the output shaft of the rotary motor is connected to the rotary bracket. The beneficial effect of the utility model is that: the output shaft of the linear motion motor is connected to the screw, and the linear motion motor can drive the screw to do linear motion when working; by setting the rotary motor and the rotary bracket, the rotary motor drives the rotary bracket to do circular rotation when working, thereby driving the screw module to do circular rotation; linear motion and circular rotation can be realized on the same screw module, which can not only improve production efficiency but also save costs and use space. The novel screw rod module of the utility model has the characteristics of being able to perform linear motion and circular rotation motion at the same time, having a wide application field, a simple structure, high production efficiency, reduced cost, and reduced use space.

Since the existing equipment has a general fixing effect on the servo motor, the equipment will affect the stability of the servo motor when in use, and the existing equipment is not easy to disassemble. Therefore, we propose a new type of coupling-free servo motor screw module. Utility Model Content
