It is widely used in the fields of aviation, aerospace, navigation, machine tools, electronic equipment, textile machinery and medical equipment.

[0003] Although the harmonic reducer has excellent high-precision characteristics, it is difficult to fully demonstrate its performance by providing data only in market promotion. Customers need more intuitive ways to see the actual performance of the product, especially in high-tech industries, where the error range must be very small.

[0004] The existing detection method is mainly to detect the speed reducer by large detection equipment, and the output is in the form of a waveform diagram, so that people can clearly see how much the transmission error is. Since the harmonic reducer is a precision mechanical product, its transmission error is difficult to directly reflect. The existing detection method is to detect the speed reducer by large detection equipment, but this detection method is not suitable for use when going out for exhibition, because such high-precision equipment must be operated indoors, and has related requirements for temperature, humidity and other external environments. At the same time, disassembly, transportation and other factors may affect the detection accuracy, so when going out for exhibition, a device is needed to more intuitively display the precision of the speed reducer.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Embodiment: A transmission precision display stand for a reducer, such as Figures 1-4 As shown, it includes a base 1, a slide rail 6, a sliding seat 7, a fixed seat 8, a second motor 9, a first reducer 10, a first turntable 11, a probe 12, a moving component and a transmission component. A moving component is provided on the left side of the top of the base 1. The slide rails 6 are symmetrically installed on the front and back of the top of the base 1. The sliding seat 7 is slidingly connected between the slide rails 6. The fixed seat 8 is installed on the top of the sliding seat 7 by bolts. The second motor 9 is installed on the left side of the right end face of the fixed seat 8 by bolts. The first reducer 10 is fixed on the right side of the right end face of the fixed seat 8. The output end of the second motor 9 is fixedly connected to the input end of the first reducer 10. The right end of the output end of the first reducer 10 is fixedly connected to the first turntable 11. Four probes 12 are evenly connected to the end face of the first turntable 11. The probes 12 are made of a material with a certain flexibility, which can not only ensure the accuracy of the detection, but also avoid damage caused by slight deviations to a certain extent. A transmission component is provided on the right side of the top of the base 1.

[0021] like Figures 1-2As shown, the moving assembly includes a first motor 2, a shaft coupling 3, a support seat 4 and a threaded rod 5, the first motor 2 is installed on the top left side of the base 1 through bolts, the threaded rod 5 is connected to the output shaft of the first motor 2 through the shaft coupling 3, the support seat 4 is installed on the top of the base 1 near the left and right ends of the threaded rod 5 through bolts, the threaded rod 5 is rotatably connected to the two support seats 4, the support seat 4 is used to provide stable support for the threaded rod 5, and the threaded rod 5 is prevented from being eccentric during operation, and the threaded rod 5 is threadedly connected with the sliding seat 7 to drive the sliding seat 7 to move left and right to adjust the position.

[0022] As shown in Figure 1 , Figure 3 and Figure 4 , the transmission assembly includes a mounting seat 13, a third motor 14, a second speed reducer 15, a second rotating disc 16 and a sensing assembly, the mounting seat 13 is installed on the top right side of the base 1 through bolts, the third motor 14 is installed on the right side of the left end face of the mounting seat 13 through bolts, the second speed reducer 15 is arranged on the left side of the left end face of the mounting seat 13, the output end of the third motor 14 is fixedly connected with the input end of the second speed reducer 15, the second rotating disc 16 is fixedly connected with the output end of the second speed reducer 15 on the left side, the second rotating disc 16 is in position correspondence with and parallel to the first rotating disc 11, the second rotating disc 16 is provided with four positioning holes 17 penetratingly arranged therein, the probe 12 is in plug-in cooperation with the positioning holes 17, and whether the probe 12 can smoothly enter the positioning holes 17 can show whether the transmission precision of the speed reducer is qualified when the display stand is running. The first rotating disc 11 and the second rotating disc 16 are provided with the sensing assembly.

[0023] As shown in Figure 3 and Figure 4 , the sensing assembly includes a position sensor 18 and a sensing block 19, the sensing block 19 is fixedly connected to the end face of the first rotating disc 11 and the second rotating disc 16, the position sensor 18 is arranged on the same height of the fixed seat 8 and the mounting seat 13, the height of the position sensor 18 is consistent with the height of the sensing block 19, and the position sensor 18 and the sensing block 19 are electrically connected, the position sensor 18 can sense the sensing block 19 when the sensing block 19 is opposite to the position sensor 18, and when both of the position sensors 18 sense the sensing block 19, it indicates that the first rotating disc 11 and the second rotating disc 16 are in the same position.

[0024] As shown in Figure 1 , Figure 3 and Figure 4 , the first motor 2, the second motor 9 and the sensing assembly are designed with standardized interfaces, which are convenient for disassembly and replacement. When a certain component fails, the user can quickly replace the corresponding module, reducing maintenance time and cost.

[0025] The base 1 serves as a fixed end and plays a role of fixing and supporting. After the first motor 2 is started, the threaded rod 5 is rotated through the shaft coupling 3, and under the action of the threaded rod 5, the whole sliding seat 7 moves left and right on the slide rail 6, so as to realize horizontal position adjustment. After the second motor 9 and the third motor 14 are started, the first speed reducer 10 and the second speed reducer 15 are driven to rotate, respectively, so as to convert high rotation speed into low speed output suitable for the operation of the first rotating disc 11 and the second rotating disc 16. Since the first rotating disc 11 and the second rotating disc 16 are connected with the output ends of the first speed reducer 10 and the second speed reducer 15, respectively, they will rotate at the same speed. Under the control of the program, the first rotating disc 11 and the second rotating disc 16 will operate at the same speed in the same direction. When the first motor 2 operates in the forward direction, the control probe 12 is inserted into the positioning hole 17. When the first motor 2 operates in the reverse direction, the control probe 12 is separated from the positioning hole 17. Although the probe 12 has a certain flexibility, the material is relatively fragile. If there is a difference in the output rotation speed of the two speed reducers, that is, the transmission accuracy is not synchronized, the probe 12 may be broken, thereby directly showing the transmission accuracy problem. When only one speed reducer operates, the other speed reducer is stationary, and the probe 12 can easily enter and exit the positioning hole 17, proving the repeated positioning accuracy of the single speed reducer. When the two speed reducers operate simultaneously, the probe 12 can smoothly enter and exit the positioning hole 17, thereby showing the transmission accuracy of the two speed reducers. The size of the positioning hole 17 is 0.02-0.05mm larger than that of the probe 12, so as to ensure that the probe 12 can smoothly enter and exit, and at the same time, ensure the detection effect. The first rotating disc 11 and the second rotating disc 16 are provided with sensing blocks 19 on the end faces. When the sensing blocks 19 are opposite to the position sensors 18, the position sensors 18 can sense the sensing blocks 19. When both of the position sensors 18 sense the sensing blocks 19, it is indicated that the first rotating disc 11 and the second rotating disc 16 are at the same position.

[0026] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
