Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and particularly relates to a pulse stroke detection tooling for a motor speed reducer. Background Art

[0002] A stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates by an angle or advances by one step. Its output angular displacement or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, only by controlling the pulse signal can the stroke be controlled, so stepper motors are often used in precise stroke control.

[0003] However, during production, the output shafts and positions of each motor are not fixed. Therefore, after installation, errors will occur in the stroke. Therefore, after the motor is produced, it is necessary to initialize the position and initialize the motor output shaft to a unified position. However, the current adjustment method is very cumbersome and requires a lot of testing equipment. Summary of the Utility Model

[0004] To solve the above technical problems, one technical solution adopted by the utility model is as follows:

[0005] A pulse stroke detection tooling for a motor speed reducer includes the motor speed reducer to be tested, and also includes a frame body and several detection mechanisms installed on the frame body. A sensor is provided on the motor speed reducer.

[0006] The detection mechanism includes at least two sets of fixing components and a detection component arranged between the two sets of fixing components; the fixing components are used to fix the motor speed reducer, and the detection component is used to detect the pulse stroke of the motor speed reducer.

[0007] The detection component includes a connecting seat and a fixing seat arranged in the connecting seat. An adjusting member is rotatably connected in the fixing seat. The fixing seat is fixedly connected to the motor speed reducer, and the adjusting member is connected to the output shaft of the motor speed reducer. When the output shaft of the motor speed reducer rotates, it can drive the adjusting member to rotate in the fixing seat.

[0008] Further, the fixing component includes an equal-height seat fixedly connected to the frame body and a base installed on the equal-height seat. A pressing rod and a driving rod are rotatably connected to the base. The pressing rod and the driving rod are hinged by a connecting rod. A pressing block is provided at one end of the pressing rod away from the base, and the pressing block is used to press the motor speed reducer.

[0009] Further, the adjusting member is provided with a groove for accommodating the output shaft of the motor speed reducer, and the output shaft of the motor speed reducer is clamped in the groove. When the motor speed reducer rotates, the output shaft drives the adjusting member to rotate.

[0010] Furthermore, the pressing block and the pressing rod are fixedly connected by screws. The pressing block includes a pressing head and a threaded rod, the pressing head and the threaded rod are fixedly connected, and the threaded rod is used to adjust the position of the pressing head.

[0011] Furthermore, the sensor is an orpiment sensor.

[0012] Advantages of the present utility model:
