Description

Technical Field

[0001] This invention relates to the field of motor performance, durability and calibration testing, and in particular to a device and method for assembling a motor, adapter plate and test bench. Background Technology

[0002] When conducting various motor performance, durability, and calibration tests in the new energy electric drive laboratory, it is necessary to frequently disassemble and reassemble the motor body and motor adapter plate, as well as adapt and reassemble the overall dynamometer test bench. To ensure the coaxiality accuracy, installation stability, and accuracy of test data, a series of replacement procedures, including motor positioning and fixing, adapter plate matching and docking, and bench coaxial calibration, need to be completed in a standardized manner. This places strict requirements on the assembly process, alignment accuracy, and operation procedures of the overall replacement. Currently, the traditional bench replacement operation in the laboratory adopts a manual step-by-step disassembly and assembly, and one-by-one alignment and debugging operation mode, which cannot achieve integrated and rapid adaptation and replacement of the motor, adapter plate, and dynamometer test bench. At the same time, in scenarios where multiple motors are tested in batches and test samples are frequently changed, it is difficult to quickly complete tooling matching and accuracy calibration. The overall replacement operation is time-consuming, labor-intensive, and has poor operability. Manual alignment deviations are large, assembly accuracy is difficult to control, and problems such as coaxiality deviation and uneven docking gaps are very likely to occur. If the replacement accuracy is not up to standard, it will directly cause problems such as abnormal motor vibration, data deviation, and equipment wear during the test. This necessitates repeated disassembly, assembly, and recalibration, significantly increasing the operation time for bench replacement and reducing the overall efficiency of motor testing. Furthermore, frequent disassembly and assembly pose a risk of damaging the motor shaft, adapter plate, and the precision structure of the dynamometer bench, further delaying the test schedule and increasing costs. Therefore, it is necessary to develop a simple, easy-to-operate, precise, safe, and reliable motor and dynamometer bench replacement architecture that enables efficient replacement and adaptation.

[0003] To solve at least one of the above problems, the present invention provides a device for assembling a motor and adapter plate with a test bench, comprising: Motor support section; The adapter plate support is connected to the motor support, the height of the motor support is adjustable, and the axis of the motor support and the axis of the adapter plate support are located in the same plane in the vertical direction. A locking assembly connects the motor support portion and the adapter plate support portion. The locking assembly locks the height of the motor support portion, thereby locking the motor support portion in a preset position.

[0004] Furthermore, the motor support portion includes: The first fixing rod is fixed to one side of the adapter plate bearing part; The fixed rod shaft is fixed on the other side of the adapter plate bearing part; The second fixing rod is sleeved outside the fixing rod pivot, and the second fixing rod can rotate on the fixing rod pivot; The flexible support body has one side fixed to the first fixing rod and the other side wrapped around the second fixing rod.

[0005] Furthermore, the motor support portion includes: The first fixed rod shaft is fixed to one side of the bearing part of the adapter plate; The second fixing rod shaft is fixed on the other side of the adapter plate bearing part; The first fixing rod is sleeved outside the first fixing rod pivot, and the first fixing rod can rotate on the first fixing rod pivot; The second fixing rod is sleeved outside the pivot of the second fixing rod, and the second fixing rod can rotate on the pivot of the second fixing rod; A flexible support body, one side of which is wrapped around the first fixing rod, and the other side of which is wrapped around the second fixing rod; The flexible support body is wound around the first fixed rod and the second fixed rod as it rotates on the first fixed rod and the second fixed rod, and the axis of the flexible support body rises as it is wound.

This invention not only achieves efficient changeover of motors and dynamometer test benches but also effectively ensures coaxial assembly accuracy, avoiding equipment damage and abnormal test data.

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please refer to Figures 1-3 In one embodiment of the present invention, the assembly device for the motor and adapter plate and the test bench includes: Motor support section; The adapter plate support is connected to the motor support, the height of the motor support is adjustable, and the axis of the motor support and the axis of the adapter plate support are in the same plane in the vertical direction; A locking assembly connects the motor support portion and the adapter plate support portion. The locking assembly locks the height of the motor support portion, thereby locking the motor support portion in a preset position.

[0017] In this embodiment, the motor support unit includes: The first fixing rod 3 is fixed to one side of the bearing part of the adapter plate; The fixed rod pivot (not shown in the figure) is fixed on the other side of the adapter plate bearing part; The second fixing rod 9 is sleeved outside the fixing rod pivot, and the second fixing rod 9 can rotate on the fixing rod pivot; The flexible support body 4 has one side fixed to the first fixing rod 3 and the other side wrapped around the second fixing rod 9. The axis of the flexible support body 4 rises as it rotates on the second fixed rod 9 and wraps around the second fixed rod 9.

[0018] The flexible support body 4 is wound around the second fixed rod 9 as it rotates on the second fixed rod 9, and the axis of the flexible support body 4 rises as it is wound. In use, by continuously rotating the second fixed rod 9 clockwise or counterclockwise, the flexible support body 4 is wound or unwound around the second fixed rod 9. Since the other end of the flexible support body 4 is fixed to the first fixed rod 3, the flexible support body 4 becomes shorter or longer, and its bottom rises or falls, thereby driving the motor located on the flexible support body 4 to rise or fall, thereby achieving alignment with the adapter plate located in the adapter plate support part. In this embodiment, in order to ensure that the axes of the motor and the adapter plate are always located in the same plane in the vertical direction, the first fixed rod 3 and the second fixed rod 9 in this invention are located on the same horizontal plane.

[0019] In the above embodiments, a manual fine-tuning method is used, that is, the height of the motor is adjusted by manually cranking the rotating handle 10. However, this is not a limitation, and those skilled in the art can use other driving methods according to actual needs. For example, electric servo fine-tuning or pneumatic adjustment, etc. Although the adjustment driving methods are different, the core of achieving automated coaxial calibration through an electronic control system still relies on the core principle of "baseline positioning + deviation fine-tuning" to achieve high-precision replacement, all of which fall within the scope of protection claimed by this invention.

[0020] In this embodiment, the locking component includes: The locking gear 8 is fixed to one end of the second fixing rod 9; The limit lock 7 is rotatably mounted on the adapter plate bearing part, and the locking gear 8 meshes with the limit lock 7.

[0021] In this embodiment, only one of the fixed rods can rotate. However, for greater precision and speed, in other embodiments of the invention, both fixed rods can rotate to simultaneously raise or lower the motor. In this example, the motor support includes: The first fixed rod shaft is fixed to one side of the bearing part of the adapter plate; The second fixing rod shaft is fixed on the other side of the adapter plate bearing part; The first fixing rod is sleeved outside the first fixing rod pivot, and the first fixing rod can rotate on the first fixing rod pivot; The second fixing rod is sleeved outside the pivot of the second fixing rod, and the second fixing rod can rotate on the pivot of the second fixing rod; A flexible support body, one side of which is wrapped around the first fixing rod, and the other side of which is wrapped around the second fixing rod; The flexible support body is wound around the first fixed rod and the second fixed rod as it rotates on the first fixed rod and the second fixed rod, and the axis of the flexible support body rises as it is wound.

[0022] In this embodiment, the locking component includes: The first locking gear is fixed to one end of the first fixing rod; The second locking gear is fixed to one end of the second fixing rod; A first limiting lock is rotatably mounted on the adapter plate bearing portion, and the first locking gear meshes with the first limiting lock. The second limiting lock is rotatably mounted on the adapter plate bearing portion, and the second locking gear meshes with the second limiting lock.

[0023] In the above embodiment, the locking assembly further includes a support rod 13, fixed to the outside of the adapter plate bearing portion and located between the limiting lock and the locking gear. The function of the support rod 13 is to share the force transmitted from the locking gear to the locking device when the locking device and the locking gear are engaged, thereby extending the life of the locking device.

[0024] The locking gear engages with the limit lock via manual rotation, but this is not a limitation. Those skilled in the art can use any known engagement and drive method according to actual needs, all of which fall within the scope of this invention. For example, magnetic / clamp-type locking. Simultaneously, the mechanical quick-release structure of the quick-locking assembly can be replaced with different locking structures such as magnetic locking, self-locking clips, or hydraulic clamping, eliminating the need for bolt fastening. Although the structural form is modified, the core purpose of quick locking and simplifies the replacement process is achieved, and all fall within the scope of this invention.

[0025] In one embodiment of the present invention, the adapter plate carrier includes: Adapter plate 5 connects the motor bearing part and the locking assembly; The slot 6 is located on the inner side of the adapter plate frame 5, and the slot 6 supports the adapter plate.

[0026] In this embodiment, the adapter plate bearing part further includes: rolling limiting rods 14, 15, and 16, which are disposed inside the slot 6, and the axis of the rolling limiting rods 14, 15, and 16 is parallel to the axis of the adapter plate frame 5.

[0027] In this embodiment, the motor support unit further includes: The rotating handle 10 is fixed to the other end of the second fixed rod 9. The rotating handle 10 drives the second fixed rod 9 to rotate, thereby causing the flexible bearing body 4 to wrap around the second fixed rod 9 as the second fixed rod 9 rotates.

[0028] In other embodiments of the present invention, the assembly device for the motor and adapter plate and the test bench further includes: Base 2, the adapter plate bearing part is fixed on the base; Roller 11 is fixed to the bottom of the base 2; Push rod 1 is fixed on the base 2.

[0029] An embodiment of the present invention also provides a method for assembling a motor and adapter plate with a test bench, using the motor and adapter plate and test bench assembly device described in any of the above claims.

[0030] In the above embodiments of the present invention, the motor is adjusted to align with the adapter plate before the entire assembly is aligned with the test bench. However, this is not a limitation. For motors and adapter plates of the same specification, the relative positions of the motor support portion and the adapter plate support portion after alignment can be fixed. Then, the motor and adapter plate can be aligned with the test bench as a whole, reducing the alignment steps.

[0031] Furthermore, in this invention, the alignment of the motor and the adapter plate is determined manually. However, this is not a limitation; those skilled in the art can modify the alignment determination method according to actual needs, and all such modifications fall within the scope of protection claimed by this invention. For example, a digitally assisted alignment alternative can be used. This involves adding digital auxiliary modules such as visual recognition and laser alignment, which, in conjunction with the tooling structure, complete coaxial calibration. Compared to purely mechanical alignment, this adds digital assistance. Of course, regardless of the method used, the corresponding additional components and methods also fall within the scope of protection claimed by this invention.

[0032] This invention discloses a universal motor and adapter plate and test bench assembly structure and usage method. The whole assembly is composed of four core components: a reference positioning component, a coaxial fine adjustment component, a quick locking component, and an adapter tooling. Each component is independently formed and cooperates with each other, with clear spatial relationship. It does not rely on external auxiliary equipment and can independently complete the precise and rapid replacement of the motor and dynamometer test bench. Those skilled in the art can directly assemble, implement and test the solution.

[0033] This invention enables two methods for changing the test bench. Method 1 allows for the installation and connection of the motor and adapter plate to the test bench as a whole. The specific operation steps are as follows: place the motor and adapter plate as a whole on 4, with both ends of 4 fixed on 3 and 9. Rotating 10 can raise and lower 4. The adapter plate is locked in 6. Push this device to dock with the test bench. 8 and 9 are an integral structure, and 5 is a bearing fit. Rotating 10 again allows for height adjustment and locking through the locking mechanism of the 8 and 7, so as to achieve shaft alignment and connection with the test bench.

[0034] Option 2 allows for the connection between the motor and the adapter plate. The specific operation is as follows: place the motor on plate 4, with both ends of 4 fixed to plates 3 and 9. Rotating plate 10 raises and lowers plate 4. Place the adapter plate on plate 6, and then rotate plate 10 to adjust and lock the height using the locking mechanism at plates 8 and 7, thus adjusting the motor's vertical height. With the adapter plate in plate 6, plates 14, 15, and 16 support it. Simultaneously, rotating the adapter plate allows for the corresponding connection between the adapter plate and the motor's mounting holes.

[0035] The standardized, integrated assembly process for the universal motor and adapter plate with the test bench employs the following steps: First, the positioning fixture is fixed to the reference end face of the dynamometer bench to complete the reference calibration. Second, the motor to be tested and the adapter plate are pre-positioned and quickly aligned using the fixture's limiting structure. Finally, the locking mechanism quickly locks the motor in place and performs minor coaxiality adjustments, eliminating the need for repeated disassembly and adjustment. Compared to the traditional manual, step-by-step disassembly and multiple calibration methods, this embodiment enables rapid assembly and adaptation of various new energy drive motors of different specifications, and is compatible with mainstream test models such as conventional permanent magnet synchronous motors and flat wire motors in the laboratory.

[0036] Through actual bench testing, the replacement scheme of this invention can reduce the replacement time of a single motor bench by more than 60%, increase the assembly coaxiality qualification rate to 99%, and completely avoid problems such as motor vibration, test data distortion, wear of precision bench structure, and motor shaft damage caused by alignment deviation. It balances replacement efficiency and assembly accuracy and is suitable for high-frequency, batch motor testing operations in the laboratory.

[0037] Compared with the prior art, the present invention has the following beneficial effects: 1. Modular integrated architecture protection: This invention adopts a modular assembly structure integrating a reference positioning component, a coaxial fine-tuning component, a quick-locking component, and an adapter tooling, replacing the traditional scattered manual disassembly and assembly structure. This enables the integrated and rapid adaptation and replacement of the motor, adapter plate, and dynamometer stand, solving the defects of the traditional replacement process being messy and having poor adaptability, and providing protection for the core structure.

[0038] 2. High-precision positioning and fine-tuning protection: The addition of a precision reference limit structure and a multi-dimensional coaxial fine-tuning structure controls the assembly positioning accuracy to 0.02mm, effectively corrects manual alignment deviations, ensures the coaxiality of the motor and dynamometer spindle, and eliminates test vibration, data deviations and equipment wear problems. This is a core protection point for precision optimization.

[0039] 3. Quick-locking and replacement process protection: The quick-release locking structure is combined with a standardized replacement process, which abandons the traditional multi-bolt step-by-step tightening and repeated calibration operation mode, greatly reducing the replacement time and improving the efficiency of test replacement. The standardized operation process and quick-release locking structure provide dual protection for both method and structure.

[0040] 4. Universal compatibility and protection for multiple models: The adapter tool 10 of this invention can be adapted to a variety of mainstream new energy drive motors such as permanent magnet synchronous motors and flat wire motors, without the need for separate customized tooling. This solves the problems of poor universality and high adaptation cost of traditional replacement tooling, and has universal protection value.
