Description

Technical Field

[0001] The utility model relates to the technical field of motor testing, and particularly relates to a general motor testing tooling. Background Art

[0002] At present, there are mainly two fixing methods during motor testing. One is to clamp and fix according to the hole pitch of the motor, and the other is to clamp and fix according to the external dimensions of the motor. During the testing process, there are many types and models of motors, and due to different design schemes of the motors, the sizes and hole pitches of the motors are diverse. The versatility of the existing tooling is poor. Since the motor and the tooling need to be tightly fitted during the testing process, when the hole pitch and the motor size change, it is difficult for the same tooling to be adapted, and it is necessary to disassemble and replace the corresponding tooling according to the hole pitch of the motor for testing.

[0003] A tooling structure is disclosed in a Chinese patent (Publication No. CN210010785U), which adopts a structure combined with a bottom plate and a support plate, enabling the orientation of the conductor to be consistent with the installation position of the tooling structure, and can improve the assembly accuracy of the product. However, it is applicable to the installation of GIS products. When testing motors, not only the stability of the support plate directly connected to the motor stator needs to be considered, but also the avoidance of other component structures on the testing device by the support plate needs to be considered. During motor testing, the support plate connecting the motor stator is located between the fixing plate and the abutting plate. One end face of the motor stator is installed on the support plate, and the other end contacts the abutting plate. A hole for the rotor shaft to pass through is opened on the fixing plate. After the rotor shaft passes through the hole on the fixing plate, it is connected to the testing element. When the models of the motors are different, not only the support plate with different connection holes needs to be replaced, but also the position of the abutting plate needs to be adjusted so that the distance between the support plate and the abutting plate can accommodate the motor stator. The distribution position of the support plate affects the distribution of the position adjustment mechanism of the abutting plate, resulting in that the abutting plate can only be adjusted in a disassembly and assembly manner, affecting the installation efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a general motor testing tooling aiming at the defects existing in the prior art. A support plate is used as the structure for installing the motor stator to be tested. Multiple groups of mating holes are arranged along the axial direction of the through hole. Each group of mating holes is combined with fasteners to realize the installation and fixation of the motor. A through groove is arranged at the bottom of the support plate for the adjustment mechanism of the abutting plate to pass through, enabling the abutting plate to be adjusted flexibly as required, jointly adapting to different models of motors, and meeting the testing requirements of multiple models of motors.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

There are feet at the bottom of the support plate, and fixing holes for mating with fixing components are provided on the feet.

[0007] Further, there are three through slots, namely a first through slot for a lead screw to pass through and two second through slots for guide rods to pass through. The second through slots are located on the sides of the first through slot.

[0008] Further, there are limiting holes between adjacent through slots to form an abutment in cooperation with an external pressing rod.

[0011] Further, there are two feet on the support plate, and the two feet are symmetrically distributed with respect to the axis of the through hole.

[0012] Further, the mounting holes corresponding to the same group of mating holes are circumferentially and uniformly distributed along the axis of the through hole.

[0025] In a typical embodiment of this utility model, as Figure 1 - Figure 2 shown, a general motor test tooling is proposed.

[0026] Currently, when testing a motor, it is necessary to fix the motor on the bottom plate 12 through a support structure, connect the rotor shaft of the motor to an external test device, and measure parameters such as torque and speed during the rotation of the motor. However, the sizes of different motors and the hole pitches of the installation positions are different, resulting in difficulty for traditional support structures to adapt to the test requirements of various motors. Based on this, this embodiment provides a general motor test tooling, which is provided with a support plate 1 with multiple sets of mating holes. The support plate 1 can cooperate with different models of motors through different mating holes to realize the fixation during motor testing. At the same time, through slots are provided as avoidance structures to meet the installation requirements of adjusting elements passing through the support plate 1.

[0027] During motor testing, the support plate 1 connected to the motor stator is located between the fixed plate 9 and the abutting plate 10. One end face of the motor stator is mounted on the support plate 1, and the other end contacts the abutting plate 10. A hole for the rotor shaft to pass through is provided on the fixed plate 9. After the rotor shaft passes through the hole on the fixed plate 9, it is connected to the test element. When the motor models are different, the mating holes matched with the motor can be adjusted so that the motor can be fixed on the corresponding mating holes to achieve connection with the support plate 1.

[0028] In order to adjust the position of the abutting plate 10 so that the distance between the support plate 1 and the abutting plate 10 can accommodate the motor stator, the support plate 1 can be configured with a corresponding lead screw adjustment mechanism. The lead screw and the guide rod 11 of the lead screw adjustment mechanism pass through the through slot on the support plate 1 and are connected to the fixed plate 9. The distribution position of the support plate 1 does not affect the working process of the lead screw and the guide rod 11, ensuring the smooth execution of the adjustment work of the abutting plate 10, so that the distance between the support plate 1 and the abutting plate 10 can adapt to the motor to be tested.

[0029] As Figure 1 shown, the general motor test tooling includes a support plate 1. The support plate 1 is provided with a through hole 3 and a through slot. The through hole 3 is a through hole for the stator shaft of the motor to pass through. A plurality of groups of mating holes are circumferentially arranged outside the through hole 3. Each group of mating holes respectively includes a plurality of mounting holes 2 distributed around the axis of the through hole 3. The stator part of the motor is fixed to the support plate 1 through the mounting holes 2.

[0030] The through slot is located at the bottom of the support plate 1 and serves as a passage for external components to pass through. In this embodiment, the through slot can serve as a passage for the lead screw and the guide rod 11 to pass through the support plate 1. The bottom of the support plate 1 is provided with floor feet 5, and the floor feet 5 are provided with fixing holes 4 for mating with fixing parts, so as to stably mount the support plate 1 on the bottom plate 12.

[0031] The support plate 1 is the basic structure of the entire test tooling and is used to install and support the motor stator to be tested. The through hole 3 is a through hole for positioning the axis of the motor to ensure accurate centering of the motor during installation. The multiple groups of mating holes circumferentially arranged outside the through hole 3 are used to achieve the installation and fixation of the motor. Each group of mating holes contains a plurality of mounting holes 2 distributed around the axis of the through hole 3, enabling the tooling to adapt to motor stators with different diameters and installation requirements. By selecting the appropriate combination of mounting holes 2 and cooperating with fasteners, the motor stator can be firmly mounted on the support plate 1.

[0032] Traditional tooling often can only adapt to motors of specific models or sizes. However, the design of multiple sets of mating holes breaks this limitation, enabling the tooling to be adapted to a variety of different models of motors, thus improving the versatility and flexibility of the tooling. By designing multiple sets of mating holes, each set containing multiple mounting holes 2, different positions and numbers of mounting holes 2 can be flexibly selected to install the motor, meeting the installation requirements of motors of different models. Fasteners can be bolts, screws, etc. When using bolts as fasteners, the mounting holes 2 are through holes penetrating the support plate 1, and bolts are used in combination with nuts to install and fix the motor; when using screws as fasteners, the mounting holes 2 are threaded holes, and the screws pass through the holes on the motor stator housing and then cooperate with the mounting holes 2.

[0033] In this embodiment, the axes of the mounting holes 2 are parallel to the axis of the through holes 3. Along the axial direction of the through holes 3, the openings of the mounting holes 2 are flush with the end face of the support plate 1. Additionally, when the mounting holes 2 are threaded holes, the mounting holes 2 can be configured as blind holes. Along the axial direction of the through holes 3, the two end faces of the support plate 1 are respectively distributed with mounting holes 2, increasing the form of the mating holes distributed on the support plate 1 and adapting to more models of motors. The use of threaded holes for the mounting holes 2 enables the fasteners to cooperate with the mounting holes 2 more conveniently, improving the convenience and stability of installation.

[0034] The parallelism between the axes of the mounting holes 2 and the axes of the through holes 3 ensures that fasteners (such as bolts, nuts, etc.) can be installed vertically and stably into the mounting holes 2, avoiding loosening or damage caused by angular deviation.

[0035] The through slot is located at the bottom of the support plate 1 and serves as a passage for external components (such as the adjustment mechanism of the abutting plate 10) to pass through, enabling the abutting plate 10 to be adjusted flexibly as needed. By opening a through slot at the bottom of the support plate 1, sufficient space for movement is provided for the adjustment mechanism of the abutting plate 10, thereby allowing the abutting plate 10 to adjust its position according to the different models and sizes of the motors, ensuring stability and accuracy during the testing process.

[0036] The floor feet 5 are arranged at the bottom of the support plate 1 and are used to stably fix the tooling on the workbench or other supporting surfaces. The floor feet 5 are provided with fixing holes 4 for mating with fixing components, facilitating the use of fixing components such as bolts and screws to firmly fix the tooling. By opening fixing holes 4 on the floor feet 5 and using fixing components (such as bolts, nuts, etc.) to connect the tooling with the workbench or other supporting surfaces, the stability and safety of the tooling during use are ensured.

[0037] Due to the high versatility of the tooling, the need to design special tooling for different models of motors is reduced, thereby lowering costs and maintenance difficulties. By quickly and conveniently installing and adjusting motors of different models for testing, work efficiency and testing efficiency are improved.

[0038] Such as Figure 1As shown in the figure, there are three through slots, namely a first through slot 7 for the lead screw to pass through and two second through slots 6 for the guide rods 11 to pass through. The second through slots 6 are located on the sides of the first through slot 7. Among them, a lead screw nut is provided on the abutting plate 10. The lead screw is matched with the lead screw nut. The two ends of the lead screw are respectively installed through rotating supports. When the lead screw is rotated, the abutting plate 10 can be driven to translate along the bottom plate 12 through the lead screw nut, so as to adjust the position of the abutting plate 10. During the movement of the abutting plate 10, in order to maintain the stability of its movement, a structure of a guide rod 11 cooperating with a linear bearing is set. The linear bearings are installed on the abutting plate 10 on both sides of the lead screw nut. The guide rod 11 is distributed parallel to the lead screw. When the abutting plate 10 moves, the linear bearing can slide along the guide rod 11 to prevent deviation, improving the accuracy and reliability of the adjustment.

[0039] Limit holes 8 are provided between adjacent through slots for forming an abutment in cooperation with an external pressing rod. The fixing plate 9 can perform abutting restraint from one side of the support plate 1, and the abutting plate 10 performs abutting restraint from the other side of the support plate 1. The pressing rod is fixed on the abutting plate 10 and moves with the abutting plate 10. The combined use of the limit hole 8 and the pressing rod can provide additional stability and support for the tooling during the adjustment process, preventing accidental movement or deformation caused by external forces. Enhancing the overall stability and safety of the tooling and improving the reliability of the test.

[0040] The through slots axially penetrate the support plate 1 along the axis of the through hole 3, and the bottom openings of the through slots are coplanar with the bottom surface of the support plate 1. This ensures that external components (such as the lead screw, guide rod 11, etc.) can smoothly pass through the support plate 1 and will not be hindered by the thickness of the support plate 1.

[0041] One end of the floor foot 5 extends outside the support plate 1, and the fixing hole 4 is opened in the part of the floor foot 5 located outside the support plate 1. This enables the fixing parts (such as bolts, nuts, etc.) to be more conveniently installed and disassembled, and at the same time provides a more stable support point for the fixation of the tooling, improving the convenience and stability of the tooling installation.

[0042] There are two floor feet 5 on the support plate 1, and the two floor feet 5 are symmetrically distributed with respect to the axis of the through hole 3. The symmetrically distributed floor feet 5 can ensure that the tooling is evenly stressed during the working process, reducing deformation or damage caused by eccentric stress. Improving the stability and durability of the tooling.

[0043] As Figure 1 shown, the corresponding mounting holes 2 of the same group of mating holes are circumferentially and evenly distributed along the axis of the through hole 3. The evenly distributed mounting holes 2 can provide a more balanced fixing force, ensuring that the motor will not shift or deform due to uneven stress during the installation process. Improving the stability and accuracy of the motor installation.

[0044] The mating holes of different groups are misaligned and distributed on the support plate 1. Engineering problem solved: The misaligned distribution avoids interference between mating holes of different groups, enabling each group of mating holes to function independently and effectively. This improves the rationality and practicality of the tooling design.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
