Description

Technical Field

[0001] The utility model belongs to the technical field of robot reducer testing, and in particular relates to an RV reducer testing platform. Background Art

[0002] As a high-precision reducer, RV reducer is widely used in robots, robot arms, robot joints and other fields, and is one of the core components of its power joints. The various performance indicators of RV reducer directly affect the robot's technical parameters such as positioning accuracy, grabbing torque and life. With the widespread application of robots, the demand for RV reducers is also increasing. In order to meet the principle of factory inspection for each unit, the demand for rapid automated testing of RV robot reducers is imminent.

[0003] Before the RV robot reducer comes off the production line, it needs to complete the load capacity, input and output efficiency and torque, operation stability and life tests, and each unit must be inspected. At present, the traditional RV reducer test bench adopts manual clamping for the reducer on the test bench, which takes a long time and requires high clamping accuracy; the clamping occupies the test bench station, which invisibly increases the total test time; in addition, the manual disassembly process of the reducer after the test is completed also takes a long time, resulting in a long total inspection time and low test efficiency, which affects the overall output of the RV reducer. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an RV reducer test bench for the problems existing in the loading test of the existing RV robot reducer.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0017] Due to the adoption of the above technical solution, the utility model can test multiple varieties of RV reducers with strong compatibility by setting the first longitudinal movement mechanism, the second longitudinal movement structure and the transverse movement mechanism. The servo motor of the utility model can input the rotational speed and torque parameters through the display screen and the electrical control cabinet, with a large load range, and the maximum torque can be tested up to 2000 N·m, which can be set according to the load required by the product to be tested.

[0019] Figure 1 It is a schematic structural diagram of the RV reducer test bench of the utility model. Detailed Embodiment

[0020] The following further describes the utility model in conjunction with the drawings and specific embodiments.

[0021] See Figure 1 , a kind of RV reducer test bench shown in the figure, including a test bench frame 100, on which an installation platform 200 for the RV robot reducer to be tested, an installation platform 300 for the input rotational speed and torque mechanism, a magnetic powder loader 400, a water chiller 500 and an electrical control cabinet 600 are installed.

[0022] The installation platform 200 for the RV robot reducer to be tested is used to install the RV robot reducer to be tested. The installation platform 200 for the RV robot reducer to be tested is installed on the test bench frame 100 through a first longitudinal movement mechanism 700. The first longitudinal movement mechanism 700 is a conventional linear module, driven by a handwheel 710 to achieve forward and backward, that is, longitudinal movement, so that the output end of the RV robot reducer installed on the installation platform 200 for the RV robot reducer to be tested is docked with the output rotational speed and torque sensor 410 on the magnetic powder loader 400, and the magnetic powder loader 400 loads the output end of the RV robot reducer to be tested through the output rotational speed and torque sensor 410.

[0023] In addition, for different models of RV reducers, the height of the installation platform 200 for the RV robot reducer to be tested can be adjusted so that the output ends of different RV reducers are docked with the output rotational speed and torque sensor 410 on the magnetic powder loader 400. The height adjustment of the installation platform 200 for the RV robot reducer to be tested can be achieved by a lifting mechanism (not shown in the figure).

[0024] The magnetic powder loader 400 is located at the rear end of the installation platform 200 of the RV robot reducer to be measured. An output rotational speed and torque sensor 410 is provided at the loading end where the magnetic powder loader 400 is connected to the output end of the RV robot reducer to be measured. After the RV robot reducer to be measured is installed on the installation platform 200 of the RV robot reducer to be measured, the installation platform 200 of the RV robot reducer to be measured is moved backward through the first longitudinal movement mechanism 700, so that the magnetic powder loader 400 loads the output end of the RV robot reducer to be measured through the output rotational speed and torque sensor 410.

[0025] The installation platform 300 of the input rotational speed and torque mechanism is installed on the test bench 100 through a second longitudinal movement mechanism 800 and a transverse movement mechanism 900.

The second longitudinal movement mechanism 800 and the transverse movement mechanism 900 are conventional linear modules, which are driven by handwheels 810 and 910 to realize forward and backward, longitudinal, left and right, that is, transverse movement.

[0026] An input rotational speed and torque input mechanism 300a is installed on the installation platform 300 of the input rotational speed and torque mechanism; the input rotational speed and torque input mechanism 300a includes a servo motor 310a and an input rotational speed and torque sensor 320a installed on the input shaft of the servo motor 310a. The servo motor 310a and the input rotational speed and torque sensor 320a are installed on the installation platform 300 of the input rotational speed and torque mechanism. The servo motor 300a is controlled by the electrical control box 600, and the input rotational speed and torque sensor 320a is signal-connected to the display screen 1000.

[0027] In addition, for different models of RV reducers, the height of the installation platform 300 of the input rotational speed and torque mechanism can be adjusted. The height adjustment of the installation platform 300 of the input rotational speed and torque mechanism can be achieved by a lifting mechanism (not shown in the figure), so that the input ends of different RV reducers are docked with the input rotational speed and torque sensor 320a on the servo motor 310a. The lifting mechanism can be installed between the installation platform 300 of the input rotational speed and torque mechanism and the transverse movement mechanism 900.

[0028] The position of the input rotational speed and torque sensor 320a on the input servo motor 310a is adjusted through the second longitudinal movement mechanism 800, the transverse movement mechanism 900 and the lifting mechanism, so that it is docked with the input end of the RV robot reducer to be measured installed on the installation platform 200 of the RV robot reducer to be measured, and the RV robot reducer to be measured is driven to work.

[0029] The inlet and outlet water pipes of the water chiller 500 are connected to the magnetic powder loader 400 to cool the magnetic powder loader. The electrical control box 600 controls the servo motor 310a of the input rotational speed and torque input mechanism 300a to input the required rotational speed and torque.

[0030] The display screen 1000 is installed on one side of the test bench 110 through the conduit 1100. The wires for signal connection between the display screen 1000 and the electrical control box 600, the output rotational speed and torque sensor 410, and the input rotational speed and torque input mechanism 300a, as well as the power supply, pass through the conduit 1100. The display screen 1000 is used to input the parameters required for the test and display the test result parameters.
