Description

Technical Field

[0001] This utility model relates to the field of motor installation technology, specifically a high-strength lightweight stepper motor support frame. Background Technology

[0002] Currently, a stepper motor is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacements. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, stepper motors are also called pulse motors.

[0003] For example, the utility model patent with publication number CN209608436U discloses an external support mounting bracket for a stepper motor, including a fixed plate and a support plate. The support plate has four strip-shaped openings, each with a movable block. A clamping plate is installed on one end face of each movable block, and a first connecting ear is welded and fixedly installed on the other end face of each movable block. A cylinder is welded and fixedly installed in the middle of the four strip-shaped openings on the support plate. A screw is threadedly connected inside the cylinder. A bearing is welded and fixedly installed on the outer end of the screw. One or more second connecting ears are welded and fixedly installed on the outer ring face of the bearing. A steel wire rope is installed between each of the second connecting ears and the first connecting ears. This utility model has a simple structure and can quickly clamp or remove motors of different sizes through forward and reverse rotation. The rotation can also synchronously drive four clamping plates, greatly increasing the efficiency of disassembly and installation. At the same time, the height of the motor can be adjusted according to the installation environment, increasing its practicality. However, there is a problem that when the screw is directly rotated by the handle, the vibration of the stepper motor is transmitted to the handle during operation. This causes the handle to rotate on its own during the use of the stepper motor, which eventually leads to the steel wire rope loosening the clamping plates and reducing the stability of the stepper motor clamping. To address this, we propose a high-strength and lightweight stepper motor support frame. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, lightweight stepper motor support frame to solve the problems mentioned in the background art.

A multi-directional limiting mechanism and a motor front-end limiting mechanism are provided on the vertical plate. The motor front-end limiting mechanism is located below the multi-directional limiting mechanism. The multi-directional limiting mechanism includes multiple circumferentially distributed motor outer end limiting arc plates. A motor body is disposed between the multiple motor outer end limiting arc plates. The multi-directional limiting mechanism is used to perform a centering and clamping action on motor bodies with different outer diameters. The motor front-end limiting mechanism is used to perform a front-end limiting action on the motor body.

[0009] Preferably, the output end of the rotating shaft is rotatably connected to the vertical plate via a bearing, and the output end of the rotating shaft passes through the vertical plate.

[0026] Specifically, the rotating shaft 53 can be rotated by the front limiting mechanism 6 of the motor. At this time, the rotating shaft 53 drives the first pulley 61 to rotate. The first pulley 61 drives the second pulley 62 to rotate through the belt 63. The second pulley 62 drives the second rotating rod 64 to rotate. The second rotating rod 64 drives the slide plate 65 to slide relative to the guide post.

The second rotating rod 64 causes the slide plate 65 to slide relative to the guide post. The slide plate 65 then drives the front fixed arc plate 68, spring 69, and front moving arc plate 610 to move. The front moving arc plate 610 then causes the second guide post 611 to slide relative to the front fixed arc plate 68. Once the front moving arc plate 610 comes into contact with the front end of the motor body 7, the stability of the motor body 7 during operation is further improved.
