Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-10 In this embodiment of the utility model, an RC model motor life testing fixture includes a base plate 1. Through holes for fixing the base plate 1 are provided at the four corners of the base plate 1. A long strip-shaped guide rail mounting groove 11 is provided at one end of the top of the base plate 1. A guide rail 5 is fixedly installed inside the guide rail mounting groove 11 by screws. The housing 2 is installed and fixed at the other end of the top of the base plate 1. The housing 2 is an open-top housing, and a first-stage reduction gear set 3 is installed inside the housing 2. One end of the input shaft and one end of the output shaft of the first-stage reduction gear set 3 extend outside the base plate 1. A motor mounting bracket 6 is slidably mounted on the guide rail 5 along the length of the guide rail 5. An RC model motor is mounted on the upper end of the motor mounting bracket 6. The guide rail 5 carries the RC model motor to move along the length of the guide rail 5 to adjust the distance between the output shaft of the RC model motor and the input shaft of the first-stage reduction gear set 3, so as to adapt to the transmission connection form of different types of connectors 9. The top of the base plate 1 is symmetrically provided with two sets of multiple threaded mounting holes 12 arranged at equal intervals on both sides of the guide rail 5, which are used to fix the motor mounting bracket 6 to the base plate 1 with screws in different positions. The lower end of the motor mounting bracket 6 has a cross-shaped through hole 61 for screws to pass through, which is used to align with a threaded mounting hole 12 below the corresponding position so that the screw can limit and fix the motor mounting bracket 6. The bottom of the motor mounting bracket 6 has a sliding groove 62 that matches the guide rail 5.
[0020] In this embodiment: the fixture can accurately simulate the actual operating conditions of the RC model, and has a high degree of versatility, automation and testing accuracy. It can efficiently and accurately evaluate the life of the RC model motor, and provide strong support for product development, quality control and performance optimization. Compared with the traditional life testing method of RC model motor, it is compatible with direct drive and multi-stage reduction tests, which reduces the testing difficulty and improves the testing efficiency.
[0021] Specifically, the RC model motor life testing fixture mainly includes a base plate 1, a housing 2, a first-stage reduction gear set 3, a cover plate 4, a guide rail 5, a motor mounting bracket 6, and connecting parts 9. The base plate 1 is used to assemble the housing 2, the motor mounting bracket 6, and the guide rail 5. The RC model motor is installed on one side of the upper end of the motor mounting bracket 6 and fixed with screws. The output shaft of the RC model motor passes through the upper outer wall of the motor mounting bracket 6 and extends to the other side of the upper end of the motor mounting bracket 6. A sliding groove 62 is opened at the lower end of the motor mounting bracket 6, which can move along the length direction of the guide rail 5. When different types of transmission connection tests are required for the RC model motor, the position of the motor mounting bracket 6 is first adjusted, that is, the motor mounting bracket 6 is pushed to move along the length direction of the guide rail 5, so that the output shaft of the RC model motor and the input shaft of the first-stage reduction gear set 3 can be easily installed and connected with different types of connecting parts 9. There is no need for cumbersome installation and debugging, which reduces the difficulty of testing and improves the efficiency of testing. It can be tested 24 hours a day without interruption, which is closer to the actual application of RC model cars. It should be noted that the first-stage reduction gear set 3 in this solution is an existing first-stage reduction gear set structure, mainly including a drive gear, a driven gear, two main shafts, and bearings and bearing sleeves that match the main shafts, which will not be described in detail here; the structure of the housing 2 is designed to match the first-stage reduction gear set 3, by opening corresponding mounting holes for mounting bearings and bearing sleeves on both ends of the housing 2. The installation process of housing 2 and first-stage reduction gear set 3 is as follows: first, assemble housing 2 on base plate 1, install first-stage reduction gear set 3 into housing 2, install bearings and bearing sleeves in the mounting holes opened on both ends of housing 2, install oil seals at the output shaft position of first-stage reduction gear set 3, and install plugs at other positions. In addition, the upper opening of the enclosure 2 is sealed by the cover plate 4, and the sealing environment inside the enclosure 2 is further improved by filling the sealing groove 21 with silicone.
[0022] Please refer to this carefully. Figures 1-10 The connector 9 includes a coupling for the transmission connection between the output shaft of the RC model motor and the input shaft of the first-stage reduction gear set 3, so as to enable the RC model motor to perform direct drive testing.
[0023] In this embodiment, the connecting component 9 mainly includes a coupling, which connects the output shaft of the RC model motor to the input shaft of the first-stage reduction gear set 3 to achieve direct drive testing of the RC model motor. Before installing the coupling, it is only necessary to push the motor mounting bracket 6 along the length direction of the guide rail 5 to adjust the position of the RC model motor, which will satisfy the installation of the coupling. After the coupling is installed, the position of the motor mounting bracket 6 can be fixed with screws to prevent the RC model motor from moving during the test.
[0024] Please refer to this carefully. Figures 1-10 The connector 9 includes a gear pair for transmission connection between the output shaft of the RC model motor and the input shaft of the first-stage reduction gear set 3, so as to enable the RC model motor to perform multi-stage reduction test.
[0025] In another embodiment, the connector 9 mainly includes a gear pair, which consists of two or more meshing gears that transmit power and motion through continuous contact between the teeth. The driving gear of the gear pair is mounted on the output shaft of the RC model motor, and the driven gear is mounted on the input shaft of the first-stage reduction gear set 3, thereby cooperating with the first-stage reduction gear set 3 to perform multi-stage reduction tests. It should be noted that after the multi-stage reduction test is completed, when a direct drive test is required, simply loosen the screws that restrict the movement of the motor mounting bracket 6, release the restriction on the movement of the motor mounting bracket 6, and at the same time remove the gear pair to make the transmission connection for the subsequent direct drive test. The operation is simple and convenient, and only the position of the motor mounting bracket 6 needs to be adjusted to meet the replacement requirements.
[0026] Please refer to this carefully. Figures 1-10 A sealing groove 21 is provided at the outer edge of the upper opening of the box 2. The sealing groove 21 is filled with silicone. A cover plate 4 is fixedly installed on the top of the box 2 by screws. An oil filling hole 41 is provided in the middle of the cover plate 4. The oil filling hole 41 is located above the cover plate 4, and a sealing screw 7 is threadedly connected to the upper opening of the oil filling hole 41. A vent hole 42 is provided at one end of the cover plate 4. A waterproof vent valve 8 is threadedly connected to the upper opening end of the vent hole 42.
[0027] In this embodiment: by opening an oil filling hole 41 and a vent hole 42 on the cover plate 4, the oil filling hole 41 is located directly above the meshing point of the drive gear and driven gear in the first-stage reduction gear set 3. By injecting oil into the oil filling hole 41, good lubrication between the drive gear and driven gear in the first-stage reduction gear set 3 can be ensured, avoiding severe wear of the drive gear and driven gear after long-term testing, which would affect the test accuracy. After the oil filling is completed, the oil filling hole 41 can be sealed with a sealing screw 7. In addition, a waterproof and breathable valve 8 was added at the vent 42, which can ensure that the box 2 can be ventilated to the outside while effectively preventing water from entering the box 2.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
