Description

Technical Field

[0001] This utility model relates to the field of motor assembly, and in particular to a motor assembly and testing device. Background Technology

[0002] The motor consists of a stator, a rotor, and a control board. During assembly, the rotor needs to be placed into the stator and then connected to the control board. The mechanical and electronic parts of the motor need to be tested during the process. Because the motor is heavy, it is easy to drop and damage the appearance during the assembly and testing process. Moreover, moving it for a long time will cause operator fatigue and reduce efficiency. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a device that facilitates positioning during motor assembly and allows for rapid docking with external testing equipment during the assembly process.

[0004] To achieve the above objectives, embodiments of this utility model provide a motor assembly and testing device, comprising:

[0005] Base: It is provided with a first through hole, and on both sides of the through hole, there are limit cylinders protruding upward along the direction perpendicular to the base;

[0006] Rotating disk: The side in contact with the base forms a sliding limiting groove for the limiting cylinder to slide in; the rotating disk forms a second through hole coaxially with the first through hole, the sliding groove is arc-shaped, and the center of the arc coincides with the second through hole; the top surface of the rotating disk surrounds the second through hole and forms several annular steps downward; several motor positioning grooves are formed along the tangent direction of the annular steps.

[0007] According to the motor assembly and testing device of this utility model embodiment, when in use, the motor is placed on the rotating disk, and each part of the motor is respectively inserted into the motor positioning groove and the annular step. The rotating disk rotates relative to the base. The two are cooperated by the limiting cylinder and the sliding limiting groove, so that the motor can rotate and move at the set rotation angle without manual flipping, and the positioning is accurate.

[0008] In addition, the motor assembly and testing device proposed in the above embodiments of this utility model may also have the following additional technical features:

[0009] Optionally, it also includes a clamping assembly that clamps the motor axially, thereby driving the motor and the rotating disk to rotate.

[0010] Optionally, it also includes a lifting cylinder and a lifting plate. The lifting cylinder has a lifting plate at its movable end. The size of the lifting plate is smaller than the first through hole and the second through hole. When the movable end of the lifting cylinder moves, it drives the lifting plate to abut against the motor, thereby pushing the motor to separate from the rotating disk.

[0011] Optionally, the circular steps may have three tiers.

[0012] Furthermore, the motor positioning groove includes a first positioning narrow groove, a second positioning wide groove, and a third positioning through groove.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] When using this invention, the motor is placed on the rotating disk, and each part of the motor is respectively inserted into the motor positioning groove and the annular step. The rotating disk rotates relative to the base, and the two are connected by the limiting cylinder and the sliding limiting groove, so that the motor can rotate and move at the set rotation angle without manual flipping, and the positioning is accurate.

[0022] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Figures 1 to 4 A motor assembly and testing device according to an embodiment of the present utility model includes:

[0025] Base 1: It is provided with a first through hole 11, and on both sides of the through hole, a limiting cylinder 12 is provided to protrude upward along the direction perpendicular to the base 1;

[0026] Rotating disk 2: The side in contact with the base 1 forms a sliding limiting groove 22 for the limiting cylinder 12 to slide in; the rotating disk 2 forms a second through hole 21 coaxially with the first through hole 11, and the sliding groove is arc-shaped with the center of the arc coinciding with the second through hole 21; by limiting the length of the groove through the arc-shaped sliding limiting groove 22, the rotation angle of the rotating disk 2 can be precisely controlled.

[0027] The top surface of the rotating disk 2 forms several annular steps 23 around the second through hole 21. Several motor positioning grooves 24 are formed along the tangent of the annular steps 23. One purpose of the second through hole 21 is to place the motor shaft. Another purpose, specifically, is to set up a structure that facilitates lifting the motor. For example, it includes a lifting cylinder and a lifting plate. The moving end of the lifting cylinder is provided with a lifting plate. The size of the lifting plate is smaller than the first through hole 11 and the second through hole 21. When the moving end of the lifting cylinder moves, it drives the lifting plate to abut against the motor and pushes the motor to separate from the rotating disk 2. With this solution, the effort required to manually remove the motor from the rotating disk 2 can be reduced when the test is completed.

[0028] In use, the motor is placed on the rotating disk 2, which can easily drive the motor to rotate. The limiting groove can accurately rotate the motor to the set position, making it convenient to use external instruments to test the various contacts of the motor.

[0029] In some embodiments, a clamping assembly is also included, which clamps the motor axially and drives the motor and the rotating disk 2 to rotate. The clamping assembly may have several jaws, which are controlled to open and close to clamp the motor housing. These jaws may be mounted on a rotary motor, which drives the jaws to rotate, thereby driving the motor to rotate. This solution can further automate the process of detecting the motor.

[0030] Optionally, the annular step 23 is three-tiered. One purpose of the annular step 23 is to accommodate the motor. Although there are many existing motor housing sizes, three steps can be set to achieve maximum compatibility with motors within a specific range. The steps need to be of a certain height. Too many steps will increase the thickness of the rotating plate. Furthermore, the minimum diameter annular step 23 is too far from the maximum diameter step, making operation inconvenient.

[0031] Furthermore, the motor positioning groove 24 includes a first positioning narrow groove, a second positioning wide groove, and a third positioning through groove. The three grooves are parallel to each other. The first positioning narrow groove and the second positioning wide groove contact the annular step 23. The positioning groove can be slid into the motor terminals and other parts. In addition, the motor positioning groove 24 can also make the annular step 23 slightly deformed, so that the annular step 23 can be made slightly smaller than the motor housing and fixed with the motor housing by interference fit. Without this positioning groove, the motor would be too tight, making it difficult to place or remove.

[0032] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
