Description

Technical Field

[0001] This utility model relates to the field of brushless motor stator frame installation technology, and in particular to a brushless motor stator frame installation fixture. Background Technology

[0002] A brushless motor stator wire frame is a component used in brushless motors. It mainly consists of the stator body, wire frame sub-rod, fixing plate, wire frame main rod, baffle, rack, rotating rod, gear one, gear two, and gear ring. The design purpose of the brushless motor stator wire frame is to improve the performance and applicability of the brushless motor. Through a series of mechanical structures, such as moving slots, trapezoidal sliders, trapezoidal grooves, throttle, positioning blocks, locking pins, and locking slots, it achieves flexibility and precision in coil winding. This design not only accommodates coils of different diameters but also allows adjustment of the distance between the coil and the rotating shaft as needed, thereby regulating the output current and efficiency of the brushless motor.

[0003] Traditional stator frame installation methods often rely on manual operation, which has several drawbacks. Firstly, the precision of manual installation is difficult to guarantee, easily leading to problems such as frame misalignment and inaccurate angles. This directly affects the motor's electrical performance, for example, causing uneven electromagnetic coupling between windings, thus reducing motor efficiency and power factor, increasing energy consumption and heat generation, and in severe cases, even causing the motor to malfunction. Secondly, manual installation is inefficient and cannot meet the demands of large-scale production, increasing production costs and time, which undoubtedly reduces a company's competitiveness in a fiercely competitive market. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a brushless motor stator mounting bracket fixture to more accurately solve the problems of the aforementioned installation methods. On the one hand, the bracket position is prone to misalignment and inaccurate angles; on the other hand, manual installation is inefficient and cannot meet the needs of large-scale production.

[0005] This utility model is achieved through the following technical solution:

A positioning seat is fixedly connected between the two mounting components on the bottom inner wall of the base, and the positioning seat is located directly below the positioning component.

[0008] Second, the installation components are equipped with guide rails, which allow operators to install the motor wire frame onto the positioning plate along the guide rails. This ensures that the wire frame is accurately placed in the predetermined position on the stator core, greatly improving the convenience and accuracy of installation. It also allows for precise control of the position and angle of the motor wire frame on the stator core, ensuring the uniformity and symmetry of the winding, thereby optimizing the electromagnetic performance of the motor and reducing problems such as motor efficiency loss, torque fluctuation, and vibration noise caused by motor wire frame installation deviations.

[0009] 3. Equipped with an adjustable clamping structure, after the motor wire frame is initially positioned, the clamping seat on the connecting plate is driven by the pressing cylinder to moderately clamp the motor wire frame, so that it fits tightly with the stator core, further ensuring the stability of the motor wire frame in the subsequent winding process, and also providing convenience for subsequent fastening operations.

[0010] Fourth, the dedicated installation structure and simple operation method reduce the time and labor costs required for motor wire frame installation. Operators do not need to have superb professional skills to quickly and accurately complete the installation of motor wire frames, which greatly improves production efficiency, shortens the motor production cycle, and enables enterprises to respond to market demands more quickly, increasing product output and sales.

[0011] Furthermore, the positioning assembly includes a pressing cylinder fixedly connected to the outer wall of one side of the vertical plate by screws, a connecting plate fixedly connected to the piston rod of the pressing cylinder, and a clamping seat fixedly connected to the bottom outer wall of the connecting plate.

[0012] Furthermore, the mounting assembly includes a push cylinder fixedly connected to the inner wall of the bottom of the base by screws, a smooth plate mounted on the piston rod of the push cylinder, and a positioning plate fixedly connected to the outer wall of one side of the smooth plate, with a guide rail provided on the outer wall of the positioning plate.

[0013] Furthermore, a stator core is provided between the clamping seat and the positioning seat.

[0014] Furthermore, a motor cable frame is provided on the guide rail of the positioning disk.

[0015] Furthermore, the top outer wall of the base is provided with an installation opening, and the positioning seat is disposed inside the installation opening.

[0016] Furthermore, symmetrically distributed buttons are installed on the inclined surface of the other side outer wall of the base.

A positioning component 4 is provided on one outer wall of the vertical plate 3, and mounting components 5 are provided on both sides of the inner wall of the base 1. A positioning seat 6 is fixedly connected between the two mounting components 5 on the bottom inner wall of the base 1, and the positioning seat 6 is located directly below the positioning component 4.

[0032] The positioning assembly 4 includes a pressing cylinder 41 fixedly connected to the outer wall of one side of the vertical plate 3 by screws, a connecting plate 42 fixedly connected to the piston rod of the pressing cylinder 41, and a pressing seat 43 fixedly connected to the bottom outer wall of the connecting plate 42.

[0033] The installation assembly 5 includes a flat-push cylinder 51 fixedly connected to the inner wall of the bottom of the base 1 by screws, a smooth plate 52 installed on the piston rod of the flat-push cylinder 51, and a positioning plate 53 fixedly connected to the outer wall of one side of the smooth plate 52, and a guide rail is provided on the outer wall of the positioning plate 53.

[0034] In this embodiment, firstly, by designing a special positioning component 4 and an installation component 5, the installation position accuracy of the motor wire frame 8 is controlled within a very small tolerance range, ensuring that the relative position of each wire slot and winding is accurate, making the air gap magnetic field distribution of the motor more uniform, thereby improving the power density and operating stability of the motor.

[0035] Second, the installation component 5 is equipped with a guide rail, which allows the operator to install the motor wire frame 8 onto the positioning plate 53 along the guide rail. This ensures that the motor wire frame 8 is accurately placed in the predetermined position on the stator core 7, greatly improving the convenience and accuracy of installation. It also allows for precise control of the position and angle of the motor wire frame 8 on the stator core 7, ensuring the uniformity and symmetry of the winding, thereby optimizing the electromagnetic performance of the motor and reducing problems such as motor efficiency loss, torque fluctuation, and vibration noise caused by installation deviations of the motor wire frame 8.

[0036] Third, it is equipped with an adjustable clamping structure. After the motor wire frame 8 is initially positioned, the clamping seat 43 on the connecting plate 42 is driven by the pressing cylinder 41 to moderately clamp the motor wire frame 8, so that it is tightly attached to the stator core 7, which further ensures the stability of the motor wire frame 8 in the subsequent winding process, and also provides convenience for the subsequent fastening operation.

[0037] Fourth, the dedicated installation structure and simple operation method reduce the time and labor costs required for the installation of the motor wire frame 8.

[0040] When using the device, first place the stator core 7 on the arc-shaped groove surface of the positioning seat 6, press the start button 10, and the pressing cylinder 41 drives the clamping seat 43 on the connecting plate 42 to press the motor wire frame 8 appropriately, so that it fits tightly with the stator core 7. Then, install the motor wire frame 8 onto the positioning plate 53 along the guide rail. The flat pushing cylinder 51 drives the smooth plate 52 to move, thereby controlling the motor wire frame 8 on the positioning plate 53 to approach and install onto the stator core 7. After the stator and wire frame of the brushless motor are assembled, the pressing cylinder 41 and the flat pushing cylinder 51 are reset in sequence, and the motor can be removed.
