[0034] First embodiment

[0035] See also Figure 1 to Figure 7The present invention provides a multifunctional test device for a reducer, including a base 101, a support frame 102, a placement table 103, a cover plate 104, a lateral moving table 105, an installation component 106, a longitudinal moving table 107, a drive component 108 and a load component 109, wherein the support frame 102 is fixed to the base 101, the placement table 103 is fixed to the support frame 102, the cover plate 104 includes a cover plate 104 body and a test component, the cover plate 104 body is rotatably arranged on the placement table 103, and the test component The components are arranged on the cover plate 104 body, the transverse moving platform 105 is slidably arranged on the placement platform 103, the mounting component 106 is fixed on the transverse moving platform 105, and is used to fix the reducer, the longitudinal moving platform 107 is slidably arranged on one side of the transverse moving platform 105, the driving component 108 is fixed on the longitudinal moving platform 107, and is used to connect with the reducer to drive the reducer to operate, and the load component 109 is arranged on one side of the transverse moving platform 105, and is used to connect with the reducer to apply a load.

[0036] In this embodiment, the base 101 serves as the foundation of the entire device and provides a stable support. The support frame 102 is fixed on the base 101, and a placement table 103 is installed on the base 101 for placing other key components.

[0037] The cover plate 104 includes two parts: the cover plate 104 body and the test assembly. The cover plate 104 body is set on the placement table 103 in a rotating manner, which is convenient for the operator to adjust the position according to needs and facilitates comprehensive testing of the reducer. The test assembly is directly set on the cover plate 104 body and can measure various indicators of the reducer.

[0038] In order to adapt to the test of reducers of different specifications, the lateral moving platform 105 is slidably arranged on the placement platform 103. The mounting assembly 106 is fixed on the lateral moving platform 105. Its main function is to ensure that the reducer to be tested can be firmly mounted on the test platform to provide guarantee for subsequent tests. The position of the mounting assembly 106 and the reducer can be adjusted by the lateral moving platform 105.

[0039] The longitudinal moving platform 107 is slidably arranged along one side of the transverse moving platform 105, and a driving assembly 108 is fixed thereon. By adjusting the longitudinal moving platform 107, the driving assembly 108 and the reducer can be aligned and connected, thereby simulating the power input situation in the actual working environment, so that the reducer can operate under close to real working conditions, thereby accurately evaluating its performance.

[0040] The test component includes multiple noise sensors 110, an infrared camera 111 and a data processor 112. The multiple noise sensors 110 are arranged on the cover plate 104 body, the infrared camera 111 is arranged on one side of the cover plate 104 body, and the data processor 112 is connected to the noise sensors 110 and the infrared camera 111.

[0041] A plurality of noise sensors 110 are cleverly arranged on the cover plate 104 body, and their function is to monitor the noise level generated by the reducer during operation. These noise sensors 110 are not only numerous but also reasonably distributed, and can fully cover the working area of ​​the reducer, thereby obtaining the most accurate noise data.

[0042] In addition, in order to further improve the comprehensiveness of the test, the test assembly also includes an infrared camera 111, which is set on one side of the cover plate 104. The main function of the infrared camera 111 is to monitor the temperature changes of the reducer in real time when it is in operation. By capturing the thermal radiation information on the surface of the reducer, the infrared camera 111 can generate a thermal image to help technicians quickly locate possible hot spots or abnormal heating areas, which is crucial for early detection of potential problems.

[0043] All collected noise and temperature data will be transmitted to the data processor 112, which is a powerful central processing unit responsible for analyzing and processing the received data. The data processor 112 is connected to all noise sensors 110 and infrared cameras 111 to ensure the stability and real-time data transmission. By analyzing the raw data, the data processor 112 can generate intuitive and easy-to-understand reports to provide technicians with important reference information about the reducer performance, such as whether the noise level meets the standard, whether there is abnormal temperature rise, etc.

[0044] The noise sensor 110 includes a mounting seat 113, an adjusting screw 114 and a noise sensor body 115. The mounting seat 113 is slidably arranged on the cover plate 104 body. The adjusting screw 114 is rotatably connected to the cover plate 104 body and is threadedly connected to the mounting seat 113. The noise sensor body 115 is arranged on the mounting seat 113.

[0045] The mounting seat 113 can slide on the cover plate 104 body, so that the operator can flexibly adjust the position of the sensor as needed to better capture the noise source. The adjustment screw 114 is rotatably connected to the cover plate 104 body and connected to the mounting seat 113 through a thread. This design allows the user to fine-tune the height of the mounting seat 113 by rotating the adjustment screw 114 to ensure that the noise sensor body 115 is in the best detection position.

[0046] The mounting assembly 106 includes a clamping plate 116 , a second screw rod 117 and a buffer pad 118 . The clamping plate 116 is slidably disposed on the transverse moving platform 105 . The second screw rod 117 is threadedly connected to the clamping plate 116 and is rotationally connected to the transverse moving platform 105 . The buffer pad 118 is disposed on the clamping plate 116 .

[0047] The clamping plate 116 is a part that directly contacts and fixes the reducer, and is slidably arranged on the transverse moving platform 105. This design allows the operator to flexibly adjust the position of the clamping plate 116 according to the specific size of the reducer to be tested. In order to further enhance the stability of fixation and the convenience of adjustment, the second screw 117 is connected to the clamping plate 116 by a thread, and is rotatably connected to the transverse moving platform 105. This means that the user can accurately control the forward and backward movement of the clamping plate 116 by rotating the second screw 117 to adapt to reducers of different sizes, and at the same time, it can provide sufficient clamping force to ensure that the reducer will not be displaced during the test.

[0048] In order to protect the reducer from physical damage that may be caused by clamping, a buffer pad 118 is provided on the clamping plate 116. This buffer pad 118 can not only provide necessary buffering during clamping to reduce wear on the reducer surface, but also increase friction to prevent the reducer from accidentally sliding.

[0049] The installation assembly 106 also includes a limit rod 119 and a locking rod 120. The limit rod 119 is slidably set on the clamping plate 116, and the locking rod 120 is rotatably set on the limit rod 119 for locking the position of the limit rod 119 after being adjusted into place. A locking groove is set on the clamping plate 116 corresponding to the above-mentioned limit rod 119.

[0050] In addition, in order to meet more complex positioning requirements, the installation assembly 106 is also equipped with a limit rod 119 and a locking rod 120. The limit rod 119 is also slidably set on the clamping plate 116, allowing additional position adjustments according to the specific shape and installation requirements of the reducer, so that the reducer can be fixed more stably. Once the limit rod 119 is adjusted into place, the locking rod 120 plays an important role. The locking rod 120 is rotatably set on the limit rod 119, and the position of the limit rod 119 can be locked to ensure that it remains unchanged during the test. Specifically, a locking groove is set on the clamping plate 116 at the position corresponding to the limit rod 119. When the limit rod 119 is adjusted to a suitable position, the locking rod 120 is rotated to be embedded in the locking groove, which can effectively prevent the limit rod 119 from loosening or shifting during the test.

[0051] The driving assembly 108 includes a driving motor 121 , a connector 122 and a connecting disk 123 . The driving motor 121 is fixed to the longitudinal moving platform 107 . The connector 122 is connected to the output end of the driving motor 121 . The connecting disk 123 is connected to the connector 122 .

[0052] The drive motor 121 serves as a power source and is fixed on the longitudinal moving platform 107. This arrangement not only ensures the stability of the position of the drive motor 121, but also allows the adaption of reducers of different sizes by adjusting the position of the longitudinal moving platform 107. The output end of the drive motor 121 is connected to the connector 122, so as to transmit the rotational force generated by the motor to subsequent components. The connector 122 acts as a bridge in this process. It not only has to withstand the torque from the drive motor 121, but also has to be able to flexibly match with different reducers. The connecting disk 123 is used to achieve a reliable connection with the reducer.

[0053] The connecting disk 123 includes a disk body 124, a plurality of sliding rods 125, a plurality of first springs 126, a plurality of connecting blocks 127, a plurality of connecting rods 128 and a control ring 129. The disk body 124 is fixed to the connecting head 122. The plurality of sliding rods 125 are slidably arranged around the disk body 124. The plurality of first springs 126 are used to respectively support the plurality of sliding rods 125. The control ring 129 is slidably arranged on the connecting head 122. The plurality of connecting blocks 127 are respectively slidably arranged on one side of the plurality of sliding rods 125. One end of the plurality of connecting rods 128 is respectively connected to the plurality of connecting blocks 127, and the other end of the plurality of connecting rods 128 is rotatably connected to the control ring 129.

[0054] The disc body 124 is directly fixed on the connector 122, forming the basic framework of the entire connection structure. In order to adapt to reducer interfaces of different specifications, a plurality of sliding clamps 125 are cleverly slidably arranged around the disc body 124. These sliding clamps 125 can move freely within a certain range to match interfaces of different diameters or shapes.

[0055] In order to ensure that the sliding card rod 125 can apply appropriate pressure when contacting the reducer and can automatically reset when not in use, each sliding card rod 125 is equipped with a first spring 126 as a support. These springs provide the necessary elastic force so that the sliding card rod 125 can fit the reducer interface tightly without causing damage to it.

[0056] In addition, the control ring 129 is slidably arranged on the connector 122, and the plurality of connection blocks 127 are slidably arranged on one side of the sliding clamp rod 125. In this way, the connection block 127 can move with the sliding clamp rod 125 to ensure uniform pressure distribution on the reducer interface. One end of the plurality of connection rods 128 is respectively connected to these connection blocks 127, and the other end is rotatably connected to the control ring 129. This design allows the operator to indirectly control the movement of all the sliding clamp rods 125 by adjusting the position of the control ring 129, thereby achieving a fast and accurate docking process.

[0057] The load assembly 109 includes a moving block 130, a connecting rod 128, a friction disk 132, a pressure plate 133, a second spring 134 and a cylinder 135. The moving block 130 is slidably arranged on the transverse moving platform 105, and the connecting rod 128 is rotatably arranged on the moving block 130 for connecting to the output end of the reducer. The friction disk 132 is fixed on the connecting rod 128, and the cylinder 135 is fixed on the moving block 130. The pressure plate 133 is connected to the output end of the cylinder 135 and is close to the friction disk 132. The second spring 134 is arranged between the pressure plate 133 and the cylinder 135.

[0058] The moving block 130 is slidably arranged on the transverse moving platform 105. This design allows the position to be adjusted according to the specific size and installation requirements of the reducer to be tested. The connecting rod 128 is rotatably arranged on the moving block 130, and its design purpose is to connect with the output end of the reducer to ensure that the power can be smoothly transmitted from the reducer to the load assembly 109. The friction disk 132 is fixed on the connecting rod 128. When the reducer is running, the friction disk 132 can simulate the real load condition, so as to test the actual working capacity of the reducer.

[0059] In order to dynamically adjust the load applied to the reducer, a cylinder 135 and a pressure plate 133 are introduced into the load assembly 109. The cylinder 135 is firmly fixed on the moving block 130, and the pressure plate 133 is connected to the output end of the cylinder 135 and is close to the friction disk 132. By adjusting the pressure of the cylinder 135, the pressing force of the pressure plate 133 on the friction disk 132 can be changed, thereby adjusting the load intensity applied to the reducer. In order to ensure the smoothness and consistency of the action of the pressure plate 133, a second spring 134 is provided between the pressure plate 133 and the cylinder 135. This not only helps to reduce the impact, but also ensures that the pressure plate 133 can maintain an appropriate pressure distribution under different load conditions.

[0060] The load assembly 109 also includes a pressure sensor 136 , a data processing unit 137 and a cylinder controller 138 . The pressure sensor 136 is disposed on one side of the pressure plate 133 , the data processing unit 137 is connected to the pressure sensor 136 , and the cylinder controller 138 is connected to the data processing unit 137 and the cylinder 135 .

[0061] In order to monitor in real time and accurately control the load applied to the reducer, the load assembly 109 is also equipped with a pressure sensor 136, a data processing unit 137 and a cylinder controller 138. The pressure sensor 136 is arranged on one side of the pressure plate 133 to monitor the pressure value applied by the pressure plate 133 to the friction disc 132. These data will be transmitted to the data processing unit 137, which is an intelligent processing center responsible for analyzing and processing the received data and feeding back the results to the operator or the automatic control system. The cylinder controller 138 is connected to the data processing unit 137 and the cylinder 135. Based on the information received from the data processing unit 137, it can accurately adjust the action of the cylinder 135 to ensure that the load applied to the reducer is always kept within a predetermined range.

[0062] In summary, the well-designed load assembly 109 not only takes into account the flexibility and accuracy of load application, but also realizes highly automated and intelligent management of the reducer load test process by integrating advanced sensing technology and intelligent control systems, which makes the test results more accurate and reliable.

[0063] Second embodiment

[0064] See also Figure 8 The present invention also provides a multifunctional test method for a reducer, comprising:

[0065] S201: placing the reducer to be tested on the mounting assembly 106 and fixing it;

[0066] The operator needs to carefully place the reducer to be tested on the pre-adjusted mounting assembly 106 and firmly fix it with components such as the clamping plate 116, the second screw 117 and the buffer pad 118. This step requires precise adjustment of the position of the reducer to ensure the smooth progress of the subsequent connection process. In addition, the use of the buffer pad 118 can avoid damage to the reducer surface and increase friction to prevent sliding.

[0067] S202 moves the transverse moving platform 105 so that the input end of the reducer is aligned with the longitudinal moving platform 107;

[0068] According to the specific size and design parameters of the reducer, the operator needs to properly adjust the position of the transverse moving platform 105 so that the input end of the reducer is accurately aligned with the longitudinal moving platform 107. This adjustment process is crucial to ensure that the drive assembly 108 can be smoothly docked with the input end of the reducer, ensuring a smooth and unobstructed power transmission path.

[0069] S203: Move the longitudinal moving platform 107 so that the driving assembly 108 is aligned with the input end of the reducer and connected;

[0070] After the input end of the reducer is aligned with the longitudinal moving platform 107, the position of the longitudinal moving platform 107 is further adjusted so that the drive assembly 108 (including the drive motor 121, the connector 122 and the connecting plate 123, etc.) is precisely aligned with the input end of the reducer and the physical connection between the two is completed. This step involves meticulous operation to ensure that power can be efficiently transmitted from the drive motor 121 to the reducer.

[0071] S204 moves the load assembly 109 to connect with the output end of the reducer, and then covers the cover plate 104;

[0072] The operator needs to move the load assembly 109 to correctly connect it to the output end of the reducer. This involves the adjustment and positioning of the moving block 130, the connecting rod 128, the friction disc 132 and other components to simulate the load conditions under actual working conditions. After the connection is completed, in order to protect the test environment and ensure the accuracy of data collection, the cover plate 104 should be carefully closed and ready to start the test.

[0073] S205 starts the driving component 108 to perform a test, and then collects test data through the test component for analysis.

[0074] The drive assembly 108 is started to operate the reducer according to the predetermined test plan, and the working status of the reducer is monitored in real time using multiple noise sensors 110, infrared cameras 111 and other test components integrated on the cover 104. These test components will collect a variety of key data including noise levels and temperature changes. All collected data will be transmitted to the data processor 112 for detailed analysis and generate a report for the technician to refer to, so as to identify any potential problems or optimization points.

[0075] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
