Technical Field

[0001] This application belongs to the technical field of motor production and testing, and more specifically, it relates to a motor support testing fixture. Background Technology

[0002] Motor supports typically refer to structures that provide rotational support for the installation of motors. In some large motors or long-shaft motors, two or more motor supports are required for rotational support. In the production of motors of the same model, it is also necessary to test the coaxiality of motor supports produced in batches to ensure motor performance and service life.

[0003] Existing motor supports include a support cover and a support shaft, with the support shaft coaxially fixed to one end face of the support cover. Currently, when testing the coaxiality of two motor supports, a benchtop coaxiality testing instrument with high-precision sensors, data acquisition, and processing systems is typically used. However, this instrument is expensive, and it is particularly difficult to implement when multiple instruments are needed to test a large number of motor supports. Utility Model Content

[0004] The purpose of this application is to provide a motor support testing fixture to solve the technical problem that the testing instruments in the prior art are expensive, especially when multiple instruments are needed to test a large number of motor supports, which is difficult to achieve.

[0005] To achieve the above objectives, the technical solution adopted in this application is: providing a motor support testing fixture, wherein the motor support includes a support cover and a support shaft, and the support shaft is coaxially fixed to one end face of the support cover; the motor support testing fixture includes: The housing has mounting ports at both ends, and the two mounting ports are coaxially arranged; and A sliding sleeve is disposed inside the housing, and its axis is parallel to the axis of the mounting port; The two ends of the housing are respectively used to connect with the two support covers, and the two support covers are respectively connected with the two mounting ports; When the support cover is fixed to the housing, the corresponding support shaft can extend into the housing for inserting the sliding sleeve.

[0006] In conjunction with the above technical solutions, in one possible implementation, the motor support testing fixture further includes: A lifting plate is disposed within the housing; and A lifting assembly, disposed within the housing, is used to drive the lifting plate to move up and down; The sliding sleeve is slidably disposed on the lifting plate along its own axial direction.

[0007] In one possible implementation, based on the above technical solutions, a slide bar parallel to the axis of the sliding sleeve is fixed on the lifting plate, and a groove adapted to the slide bar is formed at the bottom of the sliding sleeve along its own axis.

[0008] In one possible implementation, based on the above technical solutions, the cross-sections of the slider and the groove are dovetail-shaped or T-shaped.

[0009] In one possible implementation, based on the above technical solutions, a sliding hole is vertically formed in the bottom wall of the housing; the lifting assembly includes: The screw, with its bottom vertically slidably connected within the sliding hole, and its top fixed to the lifting plate; and A driving component is disposed on the housing and threadedly connected to the screw. The driving component drives the screw to move up and down by rotating itself.

[0010] In one possible implementation, based on the above technical solutions, the driving component includes: The worm gear is rotatably connected within the housing and threadedly connected to the screw; and The worm gear is horizontally rotatably connected inside the housing and meshes with the worm wheel.

[0011] In one possible implementation, based on the above technical solutions, one end of the worm gear extends out of the housing and is equipped with a handwheel.

[0012] In one possible implementation, based on the above technical solutions, a connecting plate is fixed to the top of the screw, and the connecting plate is detachably connected to the lifting plate by bolts.

[0014] In one possible implementation, based on the above technical solutions, the top of the housing is provided with an opening.

[0015] The beneficial effects of the motor support testing fixture provided in this application are as follows: Compared with the prior art, when testing the coaxiality of two motor supports, this application first fixes the two motor supports at the corresponding mounting ports so that the two support shafts are aligned. At the same time, the two support shafts are inserted into the sliding sleeve. Utilizing the cooperation between the sliding sleeve and the support shafts, when the coaxiality of the two motor supports is good, the sliding sleeve can slide smoothly on the two support shafts; if there is a deviation in coaxiality, the sliding of the sliding sleeve will be hindered. This allows for direct determination of whether the two motor supports are coaxial. The structure is simple and the operation is convenient, greatly reducing the testing cost. It is especially suitable for scenarios that require testing a large number of motor supports, improving testing efficiency and economy. Furthermore, depending on the different dimensions of the support shaft in motor supports of different specifications, the sliding sleeve can be replaced according to the required support shaft dimensions, thereby enhancing the versatility and practicality of the testing fixture.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] It should be further noted that the accompanying drawings and embodiments of this application mainly describe the concept of this application. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of this application, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0021] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0022] In a conventional motor support 1 structure, there is a disc-shaped support cover 11 and a support shaft 12 coaxially fixed to one end face of the support cover 11.

[0023] The testing fixture for the motor support provided in this application will now be described.

[0024] like Figure 1 As shown, one embodiment of this application provides a motor support testing fixture, including a housing 2 and a sliding sleeve 3; both ends of the housing 2 are provided with mounting ports 21, and the two mounting ports 21 are coaxially arranged; the sliding sleeve 3 is disposed inside the housing 2, and its axial direction is parallel to the axial direction of the mounting ports 21. The housing 2 has two ends for connecting to two support covers 11 respectively, and the two support covers 11 are respectively connected to two mounting ports 21; when the support cover 11 is fixed to the housing 2, the corresponding support shaft 12 can extend into the housing 2 for inserting the sliding sleeve 3.

[0025] Specifically, the support cover 11 is detachably connected to one side of the housing 2 by multiple bolts, which are threaded through the support cover 11 and tightened into the housing 2.

[0026] Compared with the prior art, the motor support testing fixture provided in this embodiment, when testing the coaxiality of two motor supports 1, first fixes the two motor supports 1 at the corresponding mounting ports 21 so that the two support shafts 12 are aligned. At the same time, the two support shafts 12 are inserted into the sliding sleeve 3. Utilizing the cooperation between the sliding sleeve 3 and the support shafts 12, when the coaxiality of the two motor supports 1 is good, the sliding sleeve 3 can slide smoothly on the two support shafts 12; if there is a deviation in coaxiality, the sliding of the sliding sleeve 3 will be hindered. It can directly determine whether the two motor supports 1 are coaxial. The structure is simple and the operation is convenient, which greatly reduces the testing cost. It is especially suitable for scenarios that require testing a large number of motor supports 1, improving testing efficiency and economy. Furthermore, depending on the different dimensions of the support shaft 12 in the motor support 1 of different specifications, the sliding sleeve 3 can also be replaced according to the required dimensions of the support shaft 12 to be tested, thereby enhancing the versatility and practicality of the testing fixture.

[0027] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The motor support testing fixture also includes a lifting plate 4 and a lifting assembly 5; the lifting plate 4 is installed inside the housing 2 and located below the sliding sleeve 3; the lifting assembly 5 is installed inside the housing 2 and is used to drive the lifting plate 4 to move up and down; The sliding sleeve 3 is slidably mounted on the lifting plate 4 along its own axis.

[0028] The sliding sleeve 3 slides on the lifting plate 4, which improves the stability and accuracy of the sliding sleeve 3 along its own axis. By adjusting the height of the lifting plate 4 through the lifting assembly 5, and by replacing the sliding sleeve 3 with different sizes, it can adapt to motor supports 1 of different sizes and specifications, further enhancing the versatility and practicality of the testing fixture.

[0029] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A slide bar 41 parallel to the axis of the slide sleeve 3 is fixed on the lifting plate 4, and a slide groove 31 adapted to the slide bar 41 is opened at the bottom of the slide sleeve 3 along its own axis.

[0030] The cooperation between the slide bar 41 and the slide groove 31 provides excellent guidance, ensuring that the sliding sleeve 3 slides more stably and smoothly on the lifting plate 4. During the inspection process, the sliding sleeve 3 needs to slide frequently on the lifting plate 4. This stable sliding cooperation reduces wobbling and deviation during the sliding process, improving the accuracy of the inspection. In addition, the slide bar 41 and the slide groove 31 are easy to manufacture and maintain, reducing the manufacturing cost and maintenance difficulty of the inspection tooling.

[0031] like Figures 2 to 3As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The cross-sections of the slider 41 and the groove 31 are dovetail-shaped or T-shaped.

[0032] The dovetail or T-shaped cross-section has excellent self-locking properties, preventing the sliding sleeve 3 from falling off the slide bar 41 during sliding, thus improving the safety of the inspection fixture. In actual inspection processes, various vibrations and external forces may be encountered; the dovetail or T-shaped structure can effectively resist these disturbances, ensuring that the sliding sleeve 3 always remains in the correct position during sliding.

[0033] like Figure 2 and Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottom wall of the housing 2 has a vertical sliding hole 22; the lifting assembly 5 includes a screw 51 and a drive component 52; the bottom of the screw 51 is vertically slidably connected in the sliding hole 22, and the top is fixed to the lifting plate 4; the drive component 52 is set on the housing 2 and threadedly connected to the screw 51, and the drive component 52 drives the screw 51 to lift by rotating itself.

[0034] The sliding hole 22 provides guidance for the lifting and lowering of the screw 51, ensuring that the screw 51 can lift and lower vertically, preventing the screw 51 from tilting or wobbling during the lifting and lowering process, and improving the stability of the lifting and lowering. The threaded connection between the drive component 52 and the screw 51 has good transmission accuracy. By controlling the rotation angle and speed of the drive component 52, the lifting and lowering height of the screw 51 can be precisely controlled, thereby achieving precise adjustment of the height of the sliding sleeve 3.

[0035] When inspecting motor supports 1 of different sizes and specifications, this precise height adjustment ensures a more accurate fit between the sliding sleeve 3 and the support shaft 12, improving the accuracy of the inspection. Furthermore, this structure is simple, reliable, easy to manufacture and maintain, reducing the manufacturing cost and maintenance difficulty of the inspection tooling. like Figure 2 and Figure 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The drive component 52 includes a worm gear 521 and a worm 522; the worm gear 521 is rotatably connected inside the housing 2 and threadedly connected to the screw 51; the worm 522 is rotatably connected horizontally inside the housing 2 and meshes with the worm gear 521.

[0036] First, the worm gear 521 and worm 522 transmission has a large transmission ratio, enabling a small input force to generate a large output force. This allows for easy lifting and lowering of the screw 51, reducing operational difficulty. Second, the worm gear 521 and worm 522 transmission has a self-locking function. When the driving component 52 stops rotating, the worm gear 521 and worm 522 automatically lock together, preventing the screw 51 from lifting or lowering itself due to external forces. This ensures that the sliding sleeve 3 remains stable after being adjusted to the appropriate height, improving the reliability of the detection.

[0037] Furthermore, the worm gear 521 and worm shaft 522 transmission structure is compact and occupies little space, making it suitable for use in space-constrained equipment such as testing fixtures, thus improving the space utilization rate of the equipment. At the same time, this transmission structure operates smoothly and with low noise, providing a quiet environment for testing and reducing the impact of external interference on the test results.

[0038] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: One end of the worm gear 522 extends out of the housing 2 and is equipped with a handwheel 5221.

[0039] The operator can directly control the rotation of the worm gear 522 by rotating the handwheel 5221, which in turn drives the worm wheel 521 and the screw 51 to raise and lower the sliding sleeve 3. The manual operation method is highly flexible and intuitive. The operator can adjust the height of the sliding sleeve 3 at any time according to the actual testing situation without the need for other complicated equipment or tools.

[0040] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A connecting plate 511 is fixed to the top of the screw 51, and the connecting plate 511 is detachably connected to the lifting plate 4 by bolts. Specifically, the bolts pass through the connecting plate 511 from bottom to top and are threadedly connected to the lifting plate 4.

[0041] The connecting plate 511 can be easily separated from the lifting plate 4 by means of detachable bolt connection, which facilitates the replacement or repair of the lifting plate 4 or the lifting assembly 5, reducing maintenance costs and maintenance time.

[0042] Furthermore, the detachable connection facilitates upgrades and improvements to the testing fixture. For example, when the lifting plate 4 needs improvement or replacement with a more suitable model, it can be easily disassembled and a new lifting plate 4 installed, improving the adaptability and performance of the testing fixture. Meanwhile, the bolted connection provides high connection strength, ensuring a secure and reliable connection between the connecting plate 511 and the lifting plate 4, thus guaranteeing the stability and reliability of the testing fixture.

[0043] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A guide bar is vertically fixed to the inner wall of the sliding hole 22, and a guide groove is vertically opened on the outer circumference of the screw 51, with the guide bar always located in the guide groove.

[0044] The cooperation between the guide bar and the guide groove effectively prevents the screw 51 from rotating or deviating during lifting and lowering, ensuring that the screw 51 always lifts and lowers vertically along the axis of the sliding hole 22. This improves the smoothness of the screw 51's lifting and lowering, reduces errors caused by screw 51 wobbling, and thus improves the accuracy of the inspection. In addition, the guide bar and guide groove have a simple and practical structure, are easy to manufacture and install, and reduce the manufacturing cost of the inspection tooling.

[0045] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The top of housing 2 has an opening.

[0046] The top opening design allows operators to more easily observe the operation of components inside housing 2, such as the sliding state of sliding sleeve 3 and the working status of lifting assembly 5. During inspection, any abnormalities in components can be detected in a timely manner, allowing for prompt adjustment or repair and improving the reliability of the inspection work.

[0047] Furthermore, the top opening facilitates the cleaning and maintenance of components within housing 2, extending their lifespan. When replacement or repair of components within housing 2 is required, the top opening provides greater operating space, making it easier for operators to perform tasks and reducing maintenance difficulty and costs.
