Description

Technical Field

[0001] This invention relates to the field of motor stators, specifically to a motor stator coil shaping device. Background Technology

[0002] The stator is the stationary part of the electric motor. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field, thereby generating current. There are many types of stators. According to the manufacturing process, they can be divided into: wound stators, three-piece stators, and solid stators. According to the motor operating type, they can be divided into: synchronous motor stators and asynchronous motor stators. According to the motor type, they can be divided into: generator stators and starter stators.

[0003] In existing motor stator coil shaping equipment, stator coils need to be replaced one-to-one during each shaping process. Each time a stator coil is replaced, the shaped stator coil needs to be taken out and the unshaped stator coil needs to be put into the equipment. The material taking and putting out cannot be done at the same time, which is time-consuming and reduces work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a motor stator coil shaping device to solve the problem mentioned in the background art that each time the stator coil is replaced, the shaped stator coil needs to be taken out and the unshaped stator coil needs to be put into the device. The material taking and putting out cannot be done at the same time, which is time-consuming and reduces work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor stator coil shaping device, comprising a stator coil shaping machine frame, a tray, a stator coil replacement rotating frame, and a center of gravity balance disc. A protective cover is provided above the stator coil shaping machine frame. An upper shaping pressure plate is provided at the top of the interior of the protective cover, and a lower shaping pressure plate is provided at the bottom of the interior of the protective cover. The tray is connected to the lower front end of the stator coil shaping machine frame via a mounting base. A support frame is provided above the tray, and an adjustment seat is provided at the top of the support frame. The stator coil replacement rotating frame is connected to the upper interior of the adjustment seat via a fixed slider and a fixed slide groove. The center of gravity balance disc is connected to the top of the stator coil replacement rotating frame via a rotating sleeve. A U-shaped connecting frame is provided on one side of the center of gravity balance disc, and a stator coil positioning ring is provided at one end of the U-shaped connecting frame.

[0006] In a further embodiment, the top of the center of gravity balance disc is provided with a ring handle, and the cross-section of the center of gravity balance disc is designed as a circular structure.

[0007] In a further embodiment, one end of the U-shaped connecting frame is fixedly connected to the stator coil positioning ring by a second fixing bolt, and the other end of the U-shaped connecting frame is welded to the center of gravity balance plate.

[0008] In a further embodiment, the number of stator coil positioning rings is at least four.

[0009] In a further embodiment, the fixed slider is fixedly connected to one side of the fixed groove by fastening bolts.

[0010] In a further embodiment, the stator coil positioning sleeve is provided with a bearing inside, the inner wall of the bearing is provided with anti-slip strips, and the bearing and the stator coil positioning sleeve are fixedly connected by a first fixing bolt.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In this invention, a stator coil replacement rotating frame is added to the front end of the equipment. The stator coil replacement rotating frame can assemble four sets of stator coil positioning rings into one unit, allowing four sets of stator coils to be placed at once. The stator coil replacement rotating frame can rotate parallel through the rotating sleeves. When one set of stator coil positioning rings is rotated to the position directly below the upper forming pressure plate, the stator coils can be pressed and flattened by the combination of the upper and lower forming pressure plates. After the stator coils are formed, the stator coil replacement rotating frame is rotated clockwise to align the next set of stator coils with the upper forming pressure plate. At the same time, the formed stator coils are rotated to one side, and the worker takes them out. Then, the unformed stator coils are replaced. A certain amount of time can be reserved between the two processes of picking up and placing materials, which facilitates operation and allows for simultaneous picking up and placing of stator coils, thereby saving at least half the time and improving work efficiency.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figure 1-4 An embodiment of the present invention provides a motor stator coil shaping device, comprising a stator coil shaping machine frame 4, a tray 5, a stator coil replacement rotating frame 13, and a center of gravity balance plate 17. A protective cover 1 is provided above the stator coil shaping machine frame 4. An upper shaping pressure plate 8 is provided at the top of the interior of the protective cover 1, and a lower shaping pressure plate 9 is provided at the bottom of the interior of the protective cover 1. The tray 5 is connected to the lower front end of the stator coil shaping machine frame 4 via a mounting base 3. A support frame 16 is provided above the tray 5, and an adjustment seat 6 is provided at the top of the support frame 16. The stator coil replacement rotating frame 13 is connected to the fixed slide groove 15 via a fixed slider 19 and is located inside the upper part of the adjustment seat 6. The center of gravity balance plate 17 is connected to the top of the stator coil replacement rotating frame 13 via a rotating sleeve 12. A U-shaped connecting frame 11 is provided on one side of the center of gravity balance plate 17, and a stator coil positioning ring 2 is provided at one end of the U-shaped connecting frame 11.

[0020] The protective cover 1 seals and protects the shaping space. The upper shaping plate 8 and the lower shaping plate 9 work together to shape the stator coil. The support plate 5 increases the stability of the stator coil replacement rotating frame 13. The support frame 16 connects the adjusting seat 6 and the support plate 5 into one unit. The adjusting seat 6 is used to install the fixing slide 15, which is used to adjust the position of the fixing slider 19, thereby adjusting the position of the stator coil replacement rotating frame 13. The stator coil replacement rotating frame 13 is used to assemble multiple stator coil positioning rings 2 into one unit. The stator coil positioning rings 2 are used to place and fix the stator coil. The mounting base 3 fixes the support plate 5 to the lower front end of the stator coil shaping machine frame 4, allowing the adjustment... Align the joint 6 with the table surface, loosen the fastening bolt 14, and move the stator coil replacement rotating frame 13 by fixing the slider 19 so that the stator coil positioning ring 2 is located directly below the upper shaping pressure plate 8. Tighten the fastening bolt 14 to fix the position of the stator coil replacement rotating frame 13. Place the stator coil in each stator coil positioning ring 2, hold the ring handle 7 and rotate the center of gravity balance plate 17 clockwise so that the stator coil is located below the upper shaping pressure plate 8. Drive the upper shaping pressure plate 8 to slide downward through the drive device to press and shape the stator coil. After shaping, rotate the center of gravity balance plate 17 again to replace the next set of unshaped stator coils below the upper shaping pressure plate 8 and shape the next set. At the same time, replace the shaped stator coil.

[0021] Furthermore, the top of the center of gravity balance disc 17 is provided with a ring handle 7, and the cross-section of the center of gravity balance disc 17 is designed as a circular structure.

[0022] The ring handle 7 facilitates handheld operation.

[0023] Furthermore, one end of the U-shaped connecting frame 11 is fixedly connected to the stator coil positioning ring 2 by the second fixing bolt 18, and the other end of the U-shaped connecting frame 11 is connected to the center of gravity balance plate 17 by welding.

[0024] Welding allows the other end of the U-shaped connecting frame 11 to be installed as a single unit with the center of gravity balance plate 17, making it more robust.

[0025] Furthermore, the number of stator coil positioning rings 2 is at least four.

[0026] The four stator coil positioning rings 2 can be used to install and position four sets of stator coils simultaneously.

[0027] Furthermore, the fixed slider 19 is fixedly connected to one side of the fixed slide groove 15 by fastening bolts 14.

[0028] The position of the adjusted fixed slider 19 can be fixed by tightening bolt 14.

[0029] Furthermore, the stator coil positioning sleeve 2 is provided with a bearing 20 inside, the inner wall of the bearing 20 is provided with an anti-slip strip 21, and the bearing 20 and the stator coil positioning sleeve 2 are fixedly connected by a first fixing bolt 10.

[0030] The bearing 20 is used to increase the internal rotational flexibility, making the connection between the stator coil and the upper shaping plate 8 and the lower shaping plate 9 more coordinated.

[0031] Working principle: In use, the mounting plate 5 is fixed to the lower front end of the stator coil shaping machine frame 4 via the mounting base 3, so that the adjusting seat 6 is aligned with the table surface. Loosen the fastening bolt 14, and move the stator coil replacement rotating frame 13 via the fixed slider 19, so that the stator coil positioning ring 2 is located directly below the upper shaping pressure plate 8. Tighten the fastening bolt 14 to fix the position of the stator coil replacement rotating frame 13. Place the stator coil in each stator coil positioning ring 2. Hold the ring handle 7 and rotate the center of gravity balance plate 17 clockwise, so that the stator coil is located below the upper shaping pressure plate 8. The driving device drives the upper shaping pressure plate 8 to slide downward, pressing and shaping the stator coil. After shaping, rotate the center of gravity balance plate 17 again to replace the next set of unshaped stator coils below the upper shaping pressure plate 8, and shape the next set. At the same time, replace the shaped stator coil.
