[0002] Before the harmonic reducer leaves the factory, various working indicators of the harmonic reducer need to be tested, among which the transmission accuracy between the input shaft and the output shaft of the harmonic reducer is one of them.

[0003] In the existing transmission accuracy detection of harmonic reducers, it is usually necessary to connect the input shaft and the output shaft to the motor and the encoder through a coupling transmission, drive the input shaft and the output shaft to rotate through the motor, and use the encoder to record the rotation difference between the two to obtain the transmission accuracy of the harmonic reducer.

[0004] However, in such testing work, the staff needs to disassemble and assemble the two couplings for each test of the harmonic reducer. Such a testing process is cumbersome, increases the workload of the staff, and reduces the factory testing efficiency of the transmission accuracy of the harmonic reducer. Utility Model Content

[0005] In view of the above problems, the utility model provides a harmonic reducer transmission accuracy factory test device, the purpose of which is to improve the test efficiency of the harmonic reducer transmission accuracy factory.

[0013] The beneficial effects of the utility model are as follows: in the utility model, the input shaft of the harmonic reducer is directly clamped and held tightly by the clamping component.

DETAILED DESCRIPTION

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application discloses a factory test device for the transmission accuracy of a harmonic reducer, comprising: a placement table 1 for carrying a harmonic reducer; a motor 2; a clamping component 3, which is transmission-connected to the output shaft of the motor 2 and can clamp the input shaft of the harmonic reducer; an encoder 4, which is transmission-connected to the output shaft of the harmonic reducer through a coupling; and a test host, which is electrically connected to the motor 2 and the encoder 4.

[0019] During specific use, the staff places the harmonic reducer to be tested on the storage table 1, and then starts the clamping component 3 to clamp the input shaft of the harmonic reducer. Finally, the staff manually connects the output shaft of the harmonic reducer to the encoder 4, and then starts the test host for testing.

[0020] In the utility model, the input shaft of the harmonic reducer is directly clamped and held tightly by the clamping component 3. During the test operation, the staff only needs to disassemble and assemble the coupling of the output shaft of the harmonic reducer, which simplifies the test process of the harmonic reducer, reduces the workload of the staff, and can effectively improve the factory test efficiency of the transmission accuracy of the harmonic reducer.

[0021] Preferably, in this embodiment, the clamping component 3 is a pneumatic chuck with a built-in pneumatic rotary chuck; the rotary chuck can be quickly clamped on the harmonic reducer by inflating air into the pneumatic chuck, which is convenient and quick.

[0022] Specifically, the device also includes: a slide rail 7, which is arranged on the storage table 1 and extends toward the harmonic reducer; a mobile platform, which is slidably mounted on the slide rail 7, and includes a first platform 81 and a second platform 82 for carrying the clamping component 3 and the encoder 4 respectively; a lead screw 83, which is installed parallel to the slide rail 7 and is transmission-connected to the mobile platform; and a driving component 84, which is used to drive the lead screw to rotate.

[0023] It is worth mentioning that the driving component 84 can be a servo motor 2 . The driving component 84 is also electrically connected to the test host. The housing of the pneumatic chuck is fixedly disposed on the first platform 81 .

[0024] In specific use, before conducting the test, the driving component 84 drives the lead screw 83 to rotate, thereby driving the driving platform to slide along the slide rail 7, thereby driving the encoder 4 and the clamping component 3 to approach the harmonic reducer, so that the input shaft of the harmonic reducer passes through the clamping component 3, and the staff can connect and install the output shaft of the harmonic reducer and the encoder 4; similarly, after the test, the driving component 84 drives the lead screw 83 to rotate, thereby driving the driving platform to slide along the slide rail 7, thereby driving the encoder 4 and the clamping component 3 away from the harmonic reducer, making it convenient for the staff to disassemble and assemble the harmonic reducer from the storage table 1, thereby improving the test efficiency.

[0025] Specifically, the device also includes: a plurality of telescopic components 5 (cylinders can be selected), which are installed on the storage platform along the outer contour of the harmonic reducer; a plurality of pressure blocks 6, which are arranged on the piston rod of each telescopic component 5 and can approach / move away from the harmonic reducer with the telescopic movement of the telescopic component 5.

[0026] Specifically, the device also includes: a bearing seat, the outer shell of the bearing seat is fixedly arranged on the first movable platform; a transmission shaft, which is rotatably arranged in the bearing seat, one end of which is connected to the motor 2, and the other end is connected to the clamping component 3; of course, the motor 2 is also fixedly installed with the outer shell of the bearing seat, and the motor 2 and the clamping component 3 are transmission-connected, so that the motor 2 can drive the input shaft of the harmonic reducer to rotate.

[0027] Specifically, the device further includes: a first coupling for transmission connection between the transmission shaft and the output shaft of the motor 2; and a second coupling for connection between the encoder 4 and the output shaft of the harmonic reducer.

[0028] In this embodiment, the telescopic component 5 is installed vertically. When it needs to be used, the telescopic component 5 is first inflated, and the piston rod extends to push the pressure block 6 away from the storage table 1 by a certain distance; the staff places the harmonic reducer on the storage table 1, and then cancels the inflation. The spring built into the telescopic component 5 drives the telescopic rod to contract, driving the pressure block 6 to approach the harmonic reducer and press the harmonic reducer, thereby ensuring the stability of the harmonic reducer on the storage table 1 and the accuracy of the transmission precision test.
