[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] The utility model provides a motor encoder detection device, including a base plate 1, a linear guide rail 2 is symmetrically arranged on the base plate 1, a large-scale horizontal moving platform 3 is slidably arranged on the linear guide rail 2, and the large-scale horizontal moving platform 3 is driven by a crank mechanism 6 to quickly move to the detection area position through the setting of the large-scale horizontal moving platform 3, thereby improving the movement efficiency of the detection mechanism, a height lifting platform 4 is installed above the large-scale horizontal moving platform 3, and the setting of the height lifting platform 4 makes the indicator 501 above the measured position adjustable up and down, thereby improving the flexibility of the overall detection mechanism, a slide rail 401 is provided on the height lifting platform 4, and a small-scale horizontal moving platform 402 is slidably arranged on the slide rail 401, and the small-scale horizontal moving platform An indicator clamping block 5 is fixedly connected to the table 402, and an indicator 501 is fixedly connected to the indicator clamping block 5. A crank mechanism 6 is provided on the right side of the guide rail. The crank mechanism 6 is connected to the large-scale horizontal movable platform 3 through a compressed gas spring handle 601. The large-scale horizontal movable platform 3 is pressed onto the linear guide rail 2 through the compressed gas spring handle 601. The height lifting platform 4 is a scissor-like 403 lifting structure. The left side of the scissors 403 is fixed, and the right side is driven by the screw rod 404 and limited by the slider 405. By rotating the screw rod 404, the linear motion is converted into the horizontal movement of the slider 405. The horizontal movement of the slider 405 will drive the height of the scissors 403 arm to change, thereby realizing the longitudinal displacement of the small-scale horizontal movable platform 402.

[0021] When the motor encoder detection device is actually used, the motor to be tested 8 is placed on the motor positioning platform 7, and the dial block 704 is turned to drive the motor clamp 702 to rotate on the motor positioning platform 7 until the motor to be tested 8 in the motor positioning platform 7 is clamped and limited to the right side of the positioning block 703. The crank mechanism 6 is turned to make the large-scale horizontal moving platform 3 enter the measuring position, and the small-scale horizontal moving platform 402 and the height lifting platform 4 are adjusted to make the detection head of the indicator 501 contact the measured position of the motor encoder 801. The indicator 501 displays the reading and the reasonable range. The motor spindle 802 is driven by the external drive mechanism to rotate the motor spindle 802. Turn, at this time record the maximum and minimum values ​​of the indicator table 501, calculate the difference between the maximum and minimum values, which is the motor encoder 801 jitter value. The utility model has a simple structure, stable performance, and accurate measurement. Compared with the conventional method for detecting the jitter of the motor encoder 801, the detection efficiency is low, and it is suitable for measuring the jitter of various motor encoders 801. The motor encoder 801 jitter can be measured through the flexible clamping component 701 and the lifting platform and the mobile platform, reducing the risk of measurement failure and meeting the detection of various motor encoders 801 jitter. It has reliable accuracy, fast measurement, and can adjust the measuring height and probe position. It is convenient and quick to use.

[0022] like Figure 1-3 As shown, the sliding amplitude of the large-amplitude horizontal moving platform 3 is smaller than the sliding amplitude of the small-amplitude horizontal moving platform 402, and the right side of the base plate 1 is fixedly connected to the motor positioning platform 7, and multiple groups of clamping components 701 are provided on the motor positioning platform 7. The motor 8 to be tested is restricted on the motor positioning platform 7 by the mutual cooperation of the multiple groups of clamping components 701. The motor 8 to be tested is installed on the motor positioning platform 7, and the motor 8 to be tested is fixedly connected to the motor 8 to be tested. The indicator table 501 is located above the encoder 801, and a main shaft 802 is passed through the motor 8 to be tested, and the main shaft 802 is embedded in the motor positioning platform 7. The driving rotation of the main shaft 802 is driven by an external driving mechanism.

[0023] The clamping assembly 701 includes a motor holder 702, which is threadedly connected to the motor positioning platform 7. A positioning block 703 is installed on the motor positioning platform 7. The motor 8 to be tested is set to the right of the positioning block 703. The motor holder 702 is set to the right of the motor to be tested 8. A shift block 704 is set at the end of the motor holder 702.

[0024] The effect achieved by the entire embodiment 1 is that by setting the positioning block 703 on the motor positioning platform 7, the motor to be tested 8 is abutted against the positioning block 703, and then the staff manually operates the shift block 704 to drive the motor clamp 702 to be screwed on the motor positioning platform 7 until the motor clamp 702 clamps the motor to be tested 8 to a limited position on the motor positioning platform 7. The entire motor positioning platform 7 can adapt to the limited clamping of motors of different sizes.

[0025] like Figure 1-3 As shown, the crank mechanism 6 includes a fixed block 602, which is fixedly connected to the base plate 1 by fasteners. A rotating shaft 603 is passed through the fixed block 602. A driving handle 604 is fixedly connected to the right side of the rotating shaft 603, and a driven handle 605 is fixedly connected to the left side of the rotating shaft 603. The driven handle 605 is connected to the compressed gas spring handle 601 through a crank connecting arm 606.

[0026] The effect achieved by the entire embodiment 2 is that the staff manually shakes the driving handle 604 to drive the driven handle 605 on the opposite side of the rotating shaft 603 to rotate, and the driven handle 605 is connected to the compressed gas spring handle 601 through the crank connecting arm 606. Finally, the driven handle 605 drives the crank connecting arm 606 to move, and then drives the large-scale horizontal moving platform 3 to move on the slide rail 401, completing the rapid movement of the detection mechanism. The crank mechanism 6 drives the large-scale horizontal moving platform 3 to slide, reducing the labor intensity of the staff.

[0027] Working principle: The motor to be tested is placed on the motor positioning platform, and the dial block is turned to drive the motor clamp to rotate on the motor positioning platform until the motor to be tested in the motor positioning platform is clamped and limited to the right side of the positioning block. The crank mechanism is turned to make the large-scale horizontal moving platform enter the measuring position, and the small-scale horizontal moving platform and the height lifting platform are adjusted to make the detection head of the indicator touch the measured position of the motor encoder. The indicator displays the reading and the reasonable range. The external drive mechanism drives the motor spindle to rotate the motor spindle. At this time, the maximum and minimum values ​​of the indicator are recorded, and the difference between the maximum and minimum values ​​is the motor encoder runout value.
