The electric hydraulic cylinder 203, the clamping mechanism 3 and the precision reducer 4 fixed by the clamping can be controlled to move horizontally and linearly. The electric hydraulic cylinder 203 can be used to control the clamping mechanism 3 and the precision reducer 4 fixed by the clamping to move vertically. The clamping mechanism 3 includes a U-shaped plate 301, two first electric telescopic rods 302 and two clamping plates 303. The U-shaped plate 301 is fixedly mounted on the output shaft end of the electric hydraulic cylinder 203. The two first electric telescopic rods 302 are respectively fixedly mounted on the front inner wall and the rear inner wall of the U-shaped plate 301 and are symmetrically distributed. The two clamping plates 303 The precision reducer 4 is located between the two clamping plates 303. The clamping plates 303 can be controlled to move linearly by the first electric telescopic rod 302. The precision reducer 4 can be clamped and fixed by the cooperation of the two clamping plates 303. The mounting head 5 is detachably mounted and fixed on the output shaft end of the precision reducer 4. It should be noted that the mounting head 5 can be fixed on the output shaft end of the precision reducer 4 by the existing screw assembly or other connector assembly methods. The induction target 6 is fixedly mounted on the mounting head 5 away from the precision reducer On one side wall of the speed reducer 4, a vertical plate 7 is fixedly installed on the top right side of the workbench 1. The spectrum sensor 8, the height limiting mechanism and the spacing measuring piece are all arranged on the left side wall of the vertical plate 7.

[0026] Through the above structure, the detection device for the transmission accuracy of the precision reducer provided by the utility model is convenient for adjusting the vertical spacing between the sensing target body 6 and the spectrum sensor 8 and the height position of the sensing target body 6 when in use. When the transmission accuracy of precision reducers 4 of different sizes is detected, it can ensure that the sensing target body 6 is accurately aligned with the spectrum sensor 8, and can ensure that the distance between the sensing target body 6 and the spectrum sensor 8 is constant and accurate. The operation is simple and convenient, and the accuracy of the transmission accuracy detection of the precision reducer 4 is improved. In specific operation, the precision reducer 4 is placed between the two clamping plates 303 in the U-shaped plate 301, and the operation of the two first electric telescopic rods 302 is controlled. By controlling the two clamping plates 303 to move toward each other, so that the two second anti-skid pads 305 are in tight contact with the outer walls of both sides of the precision reducer 4, the two first electric telescopic rods 302 are stopped. At this time, the stable and reliable clamping and fixing of the precision reducer 4 is completed. Then, the mounting head 5 is fixed to the output shaft end of the precision reducer 4, and the top rod 9 is vertically facing upward and the reflecting plate 10 is vertically facing downward. By controlling the extension of the second electric telescopic rod 11, the connecting plate 12 and the baffle 13 can be controlled to move horizontally and linearly to the left. Then, by controlling the electric slide 202 to slide horizontally and linearly on the electric guide rail 201, the electric hydraulic cylinder 203, the clamping mechanism 3, and the clamping mechanism 3 can be controlled. The fixed precision reducer 4, mounting head 5 and sensing target 6 move horizontally and linearly, and the push rod 9 on the mounting head 5 can be adjusted to the bottom of the baffle 13. The clamping mechanism 3, the clamped precision reducer 4, the mounting head 5 and the sensing target 6 can be controlled to rise and fall vertically by controlling the retractable characteristics of the electric hydraulic cylinder 203, and the top of the push rod 9 can be adjusted to conflict with the bottom surface of the baffle 13. At this time, the sensing target 6 can be accurately aligned with the spectrum sensor 8, and then the infrared rangefinder 14 is turned on to detect the vertical distance between the infrared rangefinder 14 and the reflector 10. Then, the electric slide 202 is controlled to move horizontally and linearly on the electric guide rail 201 to move the infrared rangefinder 14 to the reflector 10. When the vertical spacing dimension between the line rangefinder 14 and the reflector 10 is adjusted to the specified value, the vertical spacing dimension between the sensing target 6 and the spectral sensor 8 also reaches the required distance. Then turn off the infrared rangefinder 14, and control the second electric telescopic rod 11 to retract and reset, so that the connecting plate 12 and the baffle 13 can be horizontally moved right back to their original positions. By turning on the precision reducer 4, the sensing target 6 and the spectral sensor 8, the transmission accuracy detection operation can be carried out. After the detection is completed, turn off the precision reducer 4, the sensing target 6 and the spectral sensor 8, remove the mounting head 5, and remove the detected precision reducer 4 by controlling the two first electric telescopic rods 302 to retract and reset.
[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
