Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a motor clamping fixture. Background Technology

[0002] Motor testing technology is widely used in the testing of various motor performance characteristics and belongs to the field of electronic component testing. It is particularly useful for product components requiring high-precision transmission.

[0003] The principle of motor testing is relatively simple. The equipment's workbench fixes the component to be tested to the center of the workbench using various devices. During operation, the rotor contacts the equipment interface, and then the workbench rotates. The sensor transmits the test data back to the computer in real time, and the built-in software performs algorithm calculations to obtain various data of the motor.

[0004] However, during testing, the existing device is prone to wobbling and eccentricity due to unstable clamping during motor testing, which causes deviations in the test data. In addition, positioning requires more time when changing motors for testing. Summary of the Invention

[0005] The main purpose of this utility model is to propose a motor clamping fixture, which aims to solve the technical problems of unstable clamping and long clamping and positioning time.

[0006] To achieve the above objectives, this utility model proposes a motor clamping fixture, including a base. The upper end face of the base is sequentially provided with a fixed clamping plate, a movable clamping plate, a guide sleeve, and a support frame. A handle is hinged to the support frame, and one end of a connecting rod is hinged to the handle. The other end of the connecting rod is hinged to a guide rod, which passes through the guide sleeve.

[0007] In one embodiment, the upper end face of the base is provided with a positioning groove and a sliding groove in sequence. The positioning groove is used to fix the installation of the clamping plate, and the sliding groove is used to move the clamping plate laterally.

[0008] In one embodiment, the guide rod passes through and is coaxial with the guide sleeve, and the outer diameter of the guide rod and the inner diameter of the guide sleeve are clearance-fitted.

[0009] In one embodiment, a top rod is coaxially provided at the front end of the guide rod.

[0010] In one embodiment, a top rod is coaxially provided at the front end of the guide rod, and a limit hole is provided on the movable clamping plate corresponding to the top rod.

[0011] In one embodiment, a semi-circular hole is provided on the adjacent side of the fixed clamping plate and the movable clamping plate, and the size of the circular hole is clearance-fitted with the size of the motor.

[0012] In one embodiment, the gripping end of the handle is provided with anti-slip texture or anti-slip sleeve.

[0013] In one embodiment, the handle and the support frame are connected by end cap anti-loosening pins, the connecting rod and the handle are connected by end cap anti-loosening pins, and the connecting rod and the guide rod are connected by end cap anti-loosening pins.

[0014] The technical solution of this utility model involves a guide rod passing through a guide sleeve, two connecting rods connected to the guide rod, then the two connecting rods connected to the handle, then the handle connected to the support frame, and then the handle rotated clockwise to the rightmost end; select a fixed clamping plate and a movable clamping plate of appropriate size, then first connect the fixed clamping plate to the base, and then place the movable clamping plate between the fixed clamping plate and the guide rod;

[0015] Next, place the motor into the movable clamp and the fixed clamp, and then turn the handle counterclockwise to the leftmost end; this completes the clamping and positioning of the motor. After the test is completed, turn the handle clockwise to the rightmost end to remove the motor. During the test, this device clamps the motor quickly and stably without shaking. At the same time, when changing the motor for testing, the positioning time is shorter, which improves the accuracy of the experimental data and improves the testing efficiency.
