Description

Technical Field

[0001] This utility model relates to the field of equipment tooling, and in particular to a tooling tray for off-line testing of coaxial reducers. Background Technology

[0002] A coaxial reducer is a speed reduction device in which the output shaft and input shaft are located on the same straight line. Its power input and output are located on the same center line. Coaxial reducers play an extremely core role in new energy vehicles, especially pure electric vehicles, and are an indispensable component of the electric drive system. Therefore, after the coaxial reducer is manufactured, it must undergo a series of strict technical tests to ensure that its performance, reliability and lifespan meet the design requirements and customer standards.

[0003] The testing of the technical specifications of coaxial reducers mainly includes testing the transmission efficiency, rated output torque and peak torque, no-load starting torque, temperature rise and thermal balance, as well as noise and vibration. These technical specifications are the basis for measuring the capabilities of coaxial reducers. Therefore, for these testing contents, it is necessary to design a tooling pallet that can support the coaxial reducer for testing the relevant technical specifications. In response to this need, this application proposes a solution. Summary of the Invention

[0004] Purpose of the utility model: The purpose of this utility model is to provide a tooling tray for the offline testing of coaxial reducers, which supports the coaxial reducers during the offline testing process to ensure that the coaxial reducers can complete the testing.

[0005] Technical solution: The tooling tray for coaxial reducer offline testing according to this utility model includes a mother tray and a daughter tray. The daughter tray is vertically arranged on the mother tray. The center of the daughter tray is provided with an opening for loading the coaxial reducer. An adapter plate matching the outer periphery of the product is installed on the opening. An oil passage is provided inside the daughter tray, and the oil passage is connected to the oil hole on the coaxial reducer.

[0006] After the coaxial reducer to be tested is installed in the open adapter plate, the sub-plate is fixedly installed on the mother plate, thereby completing the positioning of the coaxial reducer at the test station. Oil is supplied to the coaxial reducer through the oil circuit in the sub-plate to meet the oil requirements of the coaxial reducer during the test.

[0007] Preferably, the sub-tray is provided with a quick-pressing mechanism, which includes a lead screw and a nut. The quick-pressing mechanism includes a lead screw, a nut and a pressure head. The lead screw is vertically arranged on the sub-tray, the nut is rotatably arranged on the lead screw, and the outer wall of the nut is connected to the pressure head, which drives the pressure head to move along the axial direction of the lead screw.

[0008] The coaxial reducer is fixed on the adapter plate by using the nut to drive the pressure head to move along the axial direction of the lead screw, thus completing the axial positioning of the coaxial reducer.

[0009] The quick clamping mechanism is used to fix the coaxial reducer on the adapter plate, thus completing the axial positioning of the coaxial reducer.

[0010] Preferably, the adapter plate is detachably mounted to the sub-tray via bolts.

[0011] The adapter plate is detachably mounted on the sub-tray, which makes it easy to select different models of adapter plates according to different models of coaxial reducers, thus further expanding the scope of application of this application.

[0012] Preferably, a sealing ring is provided on the end face of the adapter disk that contacts the coaxial reducer.

[0013] The sealing ring ensures that any oil that may leak out at the contact point between the sub-pallet and the coaxial reducer will not be exposed.

[0014] Preferably, the adapter plate is provided with a positioning pin, which matches the positioning hole on the coaxial reducer.

[0015] The locating pin is used to prevent the coaxial reducer from rotating inside the adapter, thus completing the radial positioning of the coaxial reducer.

[0016] Preferably, the top of the sub-tray is provided with an oil injection connector and a vent plug, and the bottom is provided with an oil drain connector. The oil injection connector and the oil drain connector block the oil passage inside the sub-tray, and the vent plug is connected to the oil passage inside the sub-tray.

[0017] The oil filling connector is used to introduce oil into the internal oil circuit of the sub-tray, the vent plug is used to balance the air pressure in the oil circuit, and the oil drain connector is used to drain the used oil.

[0018] Preferably, the mother tray is provided with multiple positioning pin holes, and the child tray is provided with multiple positioning pins. The positioning pins and positioning pin holes are provided in a one-to-one correspondence to fix the child tray and the mother tray.

[0019] The positioning pins and positioning pin holes are fitted together to ensure the stable installation of the sub-pallet and the mother pallet, thus ensuring the stability of the tooling pallet throughout the entire testing process.
