The planetary reducer is arranged on the upper right side of the base, and the locking frame is provided on the upper right side of the base. The locking frame is fixedly connected to the input end of the planetary reducer. Support plates are provided on the front and rear sides of the left side of the base, and the pressing mechanism is provided on the support plates.

A dial indicator is provided on both support plates, and a pointer is provided on the dial indicator. The pointer rests against the lower side of the rotating rod.

[0007] As an improvement to the above solution, the pressing mechanism includes a cylinder, a pressing rod, a pressing block, and an elastic element. Cylinders are installed on the upper part of both support plates. The piston of the cylinder is connected to the pressing rod. The pressing block is slidably provided on the lower side of the pressing rod. An elastic element is connected between the pressing rod and the pressing block. The two pressing blocks abut against the front and rear ends of the rotating rod, respectively.

[0008] As an improvement to the above solution, it also includes a pressing plate. Pressing plates are provided at both ends of the rotating rod, and two pressing blocks abut against the upper side of the two pressing plates respectively.

[0009] As an improvement to the above solution, the connecting rod is fixed to the output shaft of the planetary reducer by a threaded connection.

[0010] As an improvement to the above solution, the input end of the planetary reducer is connected to the locking frame using a clamping device.

[0011] As an improvement to the above solution, the bottom of the base is provided with an anti-slip rubber pad.

[0012] The beneficial effects of this utility model are: 1. This utility model, through the design of the pressing mechanism, rotating rod and dial indicator, uses the dial indicator reading combined with the length of the rotating rod to calculate the angle error, which can accurately measure the accuracy of the planetary reducer. Moreover, the structure is simple and the operation is convenient. After the planetary reducer is installed, it can be tested automatically, which reduces the testing cost.

[0013] 2. This utility model, through the design of the pressing plate, disperses the concentrated pressure of the pressing block over a larger area, which helps to protect the surface of the rotating rod from local indentations or damage and extends the service life of the equipment; the anti-slip rubber pad set at the bottom of the base effectively avoids unnecessary sliding of the equipment during the testing process, thereby ensuring the safety of the testing environment and the reliability of the testing results.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] A precision testing device for planetary gear reducers, such as Figures 1-4 As shown, the system includes a base 1, a planetary reducer 2, a connecting rod 21, a locking frame 3, a support plate 4, a pressing mechanism, a rotating rod 9, a dial indicator 11, and a pointer 111. The planetary reducer 2 is located on the upper right side of the base 1. The left and right sides of the planetary reducer 2 are the output shaft and the input end, respectively. The locking frame 3 is located on the upper right side of the base 1 and is fixedly connected to the input end of the planetary reducer 2. Support plates 4 are located on the front and rear sides of the left side of the base 1. A pressing mechanism is located on the upper part of the support plate 4. The connecting rod 21 is rotatably located in the middle of the upper side of the base 1. The connecting rod 21 is set in the left and right direction, and its central axis is aligned with the output shaft of the planetary reducer 2. A rotating rod 9 is located at the left end of the connecting rod 21. The pressing mechanism is used to press the rotating rod 9. A dial indicator 11 is located on both support plates 4. The dial indicator 11 has a pointer 111, which rests against the lower side of the rotating rod 9.

[0021] In use, the input end of the planetary reducer 2 is connected and fixed by the locking bracket 3. Then, the output shaft of the planetary reducer 2 is connected to the connecting rod 21. Next, the pressing mechanism on one side presses one end of the rotating rod 9 and records the reading of the dial indicator 11 on the same side. Then, the pressing stops, and at the same time, the pressing mechanism on the other side presses the other end of the rotating rod 9 and records the reading of the dial indicator 11 on the same side. The angle error is calculated by combining the values ​​recorded by the two dial indicators 11 and the length of the rotating rod 9.

[0022] like Figures 1-3 As shown, the pressing mechanism includes a cylinder 5, a pressing rod 6, a pressing block 7, and an elastic element 8. Cylinders 5 are installed on the upper part of both support plates 4. The piston of the cylinder 5 is connected to the pressing rod 6. The pressing block 7 is slidably provided on the lower side of the pressing rod 6. An elastic element 8 is connected between the pressing rod 6 and the pressing block 7. The two pressing blocks 7 are respectively pressed against the front and rear ends of the rotating rod 9. When it is necessary to press one end of the rotating rod 9, the piston of the cylinder 5 drives the pressing rod 6 to move downward, and the pressing block 7 presses one end of the rotating rod 9. At this time, the pressing block 7 slides on the pressing rod 6, and the elastic element 8 contracts to apply stable pressure.

[0023] like Figures 1-3 As shown, it also includes a pressing plate 10. The front and rear ends of the rotating rod 9 are provided with pressing plates 10. Two pressing blocks 7 are respectively pressed against the upper side of the two pressing plates 10. The pressing plates 10 disperse the concentrated pressure of the pressing blocks 7 to a larger area, reducing local indentations or damage to the surface of the rotating rod 9.

[0024] The connecting rod 21 is fixed to the output shaft of the planetary reducer 2 by a threaded connection. The threaded connection facilitates the quick installation and disassembly of the planetary reducer 2 and the testing equipment, thereby improving testing efficiency.

[0025] The input end of the planetary reducer 2 is connected to the locking frame 3 by a clamping device. The clamping device can firmly clamp the input end of the planetary reducer 2, eliminate the degree of freedom of the input end, and avoid errors caused by the shaking of the input end during testing.

[0026] The bottom of base 1 is equipped with an anti-slip rubber pad to prevent the equipment from sliding during testing and affecting the test results.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
