Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a stepper motor with an improved mechanism. Background Technology

[0002] As an open-loop control element that converts electrical pulse signals into angular or linear displacement, the stepper motor has advantages such as simple structure, convenient control, and low cost. However, traditional stepper motors often suffer from problems such as large step angle error, frequent step loss, and significant noise and vibration when running at high speed or positioning with high precision, which limits their widespread use in high-end applications. Therefore, developing a stepper motor with an improved mechanism is of great practical significance.

[0003] A stepper motor with an improved mechanism, as described in reference announcement number CN218216970U, includes a motor body, an adjustment mechanism, a mounting plate, and a telescopic rod. The adjustment mechanism is located on the back of the motor body, and telescopic rods are connected to both sides of the mounting plate. The output end of the telescopic rods is connected to the bottom of the adjustment mechanism. The adjustment mechanism includes a mounting shell, an adjusting threaded rod, a threaded sleeve, and a moving column. The adjusting threaded rod is rotatably connected to the center of the inner wall of the mounting shell, and a threaded sleeve is threaded onto the surface of the adjusting threaded rod. A moving column is fixedly connected to the center of the threaded sleeve. A back plate is fixedly connected to the center of the back of the motor body, and one end of the moving column is fixedly connected to the back plate. A lifting stud is rotatably connected to the top of the mounting plate. This stepper motor with the improved mechanism allows for easy fine-tuning of the motor shaft position after installation, facilitating accurate shaft alignment and improving work efficiency. However, while this stepper motor can be widely used, it is generally not convenient to quickly disassemble the motor body, making disassembly and maintenance difficult and causing inconvenience for users.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepper motor with an improved mechanism, comprising a base, a support plate on the top of the base, a vertical plate on one side of the top of the support plate, a belt drive mechanism on the outer wall of one side of the vertical plate, guide rods on the outer walls of the vertical plates on both sides of the belt drive mechanism via brackets, a linkage seat on the outer wall of one side of the belt drive mechanism, the linkage seat being movably connected to the guide rods, an L-shaped component seat on the outer wall of the linkage seat, a motor body mounted at the bottom of the L-shaped component seat, a clamping plate at the bottom of the L-shaped component seat on one side of the motor body, the inner wall of the clamping plate contacting the outer wall of one side of the motor body, a side seat body at the bottom of the L-shaped component seat on the side of the motor body away from the clamping plate, two connecting rods on the outer wall of the side seat body, a side connecting plate at the end of the connecting rod away from the side seat body, a telescopic drive component mounted on the outer wall of the side connecting plate, one end of the telescopic drive component penetrating the side connecting plate and having a clamping block, and the end of the clamping block away from the telescopic drive component penetrating the side seat body.

[0008] Preferably, two L-shaped positioning seats are provided on the outer walls of both sides of the base. Positioning holes are provided on both sides of the interior of the L-shaped positioning seats. Both ends of the positioning holes extend to the outside of the L-shaped positioning seats. The positioning holes are provided so that the base can be bolted and positioned by means of bolts.

[0009] Preferably, the top of the base on both sides of the lead screw is provided with a guide rail, and the top of the guide rail is slidably connected to the bottom of the bearing plate. The guide rail is provided to limit the movement range of the bearing plate.

When the second rotary drive unit drives the belt drive mechanism to operate, the belt drive mechanism drives the L-shaped mounting seat to slide on the outer wall of the guide rod to adjust the motor body by lifting and lowering, thereby achieving the purpose of automatically adjusting and connecting the rotating shaft of the motor body.

[0015] (3) By using bolts to pass through the positioning holes and screw them into the threaded holes reserved on the mounting platform, the base can be positioned and placed on the mounting platform, thus ensuring the stability of the stepper motor after installation. Attached Figure Description
