Description

Technical Field

[0001] This utility model relates to the field of coaxial reducer testing equipment, and in particular to a device for limiting and loading / unloading sun gear tooling. 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] Therefore, in response to this need, a test tray and sun gear fixture specifically designed for testing coaxial reducers have been developed. However, in actual use, it has been found that the axial positioning of the sun gear fixture using bolts and other structures after it has been installed or removed from the test tray is quite cumbersome, resulting in a long testing time and low efficiency. To address this problem, 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 device for limiting and unloading sun gear fixtures, which completes the axis limiting of the sun gear fixtures and facilitates the installation or disassembly of the sun gear fixtures, thereby reducing the overall inspection time and improving inspection efficiency.

[0005] Technical Solution: The present invention provides a device for limiting and loading / unloading a sun gear tooling, comprising several limiting components evenly installed on the end face of an adapter plate in a test tray, and a quick-release component for opening the limiting components. The quick-release component is disposed on the end face of the limiting component and has several guide grooves, each corresponding to a limiting component. One end of a movable pin in the limiting component extends into the guide groove, and the other end is connected to a spring pressure plate. The spring pressure plate pops out toward the center of the adapter plate.

[0006] The spring plate in the limiting assembly is used to axially limit the sun gear fixture installed in the test tray. At the same time, the guide groove drives the movable pin to rotate, thereby driving the spring plate to move radially towards the adapter plate, and finally opening the limiting assembly to facilitate the installation and removal of the sun gear fixture.

[0007] Preferably, the limiting component also includes a base and a spring. The base is fixedly connected to the adapter plate by bolts. A baffle is provided on the side of the base near the outer circle of the adapter plate. A spring is provided on the baffle plate facing the center of the adapter plate. The other end of the spring is connected to a spring pressure plate.

[0008] The spring is used to reset the spring plate. When the spring plate is in the reset state, it completes the axial limiting of the sun gear tooling.

[0009] Preferably, when the spring plate is fully compressed onto the base, the end of the spring plate does not extend beyond the edge of the inner ring of the adapter disc.

[0010] This design ensures that the spring plate is fully retracted into the base, without affecting the insertion and removal of the sun gear fixture.

[0011] Preferably, the quick-release assembly further includes an annular plate, the plate being the same size as the adapter plate, and the guide groove and the limiting component being respectively disposed on the plate, with the guide groove being tangent to the arc of the plate.

[0012] The guide groove is tangent to the arc of the plate, so that the plate can apply force to the movable pin by the side of the guide groove during rotation, drive the movable pin to move, compress the spring pressure plate, and open the limit assembly.

[0013] Preferably, the outer ring of the plate is provided with a number of external coarse positioning pins. The external coarse positioning pins are evenly distributed on the edge of the outer ring of the plate and are arranged in opposite directions. The external coarse positioning pins facing the adapter disk are in contact with the outer periphery of the adapter disk.

[0014] The external coarse locating pin facing the adapter plate can support the plate to be connected to the adapter plate, while the external coarse locating pin facing the other side can serve as a handle to facilitate the operator to rotate the plate.

[0015] Preferably, the outer wall of the external coarse positioning pin is a smooth outer wall.

[0016] The smooth outer wall allows the plate to rotate more smoothly and will not cause wear against the outer wall of the adapter disc.

[0017] Preferably, the inner ring of the plate is provided with an arc-shaped groove, and the arc-shaped groove contains a protrusion on the adapter plate.

[0018] The arc-shaped groove is designed to accommodate the bumps on the adapter plate, preventing the bumps from obstructing the rotation of the plate during rotation.

[0019] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0020] This application utilizes a spring pressure plate to achieve axial positioning of the sun gear tooling, and uses a guide groove to drive the movable pin to move, thereby realizing rapid adjustment of the position of the spring pressure plate and rapid opening and closing of the limiting component. This makes the sun gear tooling easier to install and disassemble, and improves testing efficiency. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0027] See appendix Figures 1-5 The figure shows a device for limiting and loading / unloading a sun gear fixture, comprising three limiting components 3 evenly installed on the end face of the adapter plate 2 in the test tray 1, and a quick-release component 4 for opening the limiting components 3. The quick-release component 4 is provided on the end face of the limiting components 3, and has three guide grooves 41, each corresponding to a limiting component 3. One end of the movable pin 31 in the limiting component 3 extends into the guide groove 41, and the other end is connected to a spring pressure plate 32. The spring pressure plate 32 pops out towards the center of the adapter plate 2. By using the spring pressure plate 32 in the limiting component 3, the axial limiting of the sun gear fixture 5 installed in the test tray 1 is achieved. At the same time, the guide groove 41 drives the movable pin 31 to rotate, thereby driving the spring pressure plate 32 to move radially towards the adapter plate 2, and finally opening the limiting component 3, facilitating the installation and disassembly of the sun gear fixture 5.

[0028] In this embodiment, the limiting component 3 also includes a base 33 and a spring 34. The base 33 is fixedly connected to the adapter plate 2 by bolts. A baffle 35 is provided on the side of the base 33 near the outer circle of the adapter plate 2. A spring 34 is provided on the baffle 35 facing the center of the adapter plate 2. The other end of the spring 34 is connected to a spring pressure plate 32. The spring 34 is used to reset the spring pressure plate 32. When the spring pressure plate 32 is in the reset state, it completes the axial limiting of the sun gear tooling 5.

[0029] In this embodiment, when the spring pressure plate 32 is fully compressed onto the base 33, the end of the spring pressure plate 32 does not extend beyond the edge of the inner ring of the adapter disc 2. This setting ensures that the spring pressure plate 32 is fully retracted into the base 33 and will not affect the insertion and removal of the sun gear tooling 5.

[0030] In this embodiment, the quick-release assembly 4 also includes an annular plate 42, which is the same size as the adapter plate 2. The guide groove 41 is provided on the plate 42 in a one-to-one correspondence with the limiting assembly 3. The guide groove 41 is tangent to the arc of the plate 42, so that the plate 42 can apply force to the movable pin 31 by the side of the guide groove 41 during rotation, thereby driving the movable pin 31 to move, compressing the spring pressure plate 32, and opening the limiting assembly 3.

[0031] In this embodiment, five external coarse positioning pins 43 are provided on the edge of the outer ring of the plate 42. The external coarse positioning pins 43 are evenly distributed on the edge of the outer ring of the plate 42 and are arranged in opposite directions. The three external coarse positioning pins 43 facing the adapter disk 2 are in contact with the outer periphery of the adapter disk 2, which can support the plate 42 to be connected to the adapter disk 2. The two external coarse positioning pins 43 facing the other side can serve as handles, making it convenient for the operator to rotate the plate.

[0032] In this embodiment, the outer wall of the external coarse positioning pin 43 is a smooth outer wall, which makes the plate 42 rotate more smoothly and will not wear against the outer wall of the outer ring of the adapter plate 2.

[0033] In this embodiment, an arc-shaped groove 44 is provided on the inner ring of the plate 42. The arc-shaped groove 44 contains a protrusion 6 on the adapter disk 2 to prevent the protrusion 6 from hindering the rotation of the plate 42 during rotation.
