[0002] As a system capable of realizing the conversion between mechanical and electrical energy, the structure of an electric machine is composed of electrical systems and mechanical systems such as a stator, a rotor and bearings. The rotor is an important component of a motor and a generator, and functions to provide a rotating magnetic field.

DETAILED DESCRIPTION

[0038] The present application will be further illustrated in conjunction with the drawings and specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the present application and not to limit the scope of the present application.

[0039] As Figure 1 and 2 shown, the permanent magnet motor magnetic pole pushing device of the present application comprises a frame 1, a pole group pairing device 2, a feeding device 3, a whole pole pushing device 4, a rotor rotating device 5, a rotor support frame 6, a hydraulic station and an electric control box. The present application is optimized and improved on the basis of the traditional horizontal magnetic pole box pushing device, designs a pole group pairing module and a feeding device, avoids manual handling of magnetic pole boxes on the table position, greatly increases safety, and greatly improves pushing efficiency through the whole pole pushing device and the rotating device, saves manpower and time cost.

[0040] The working principle is: first, the magnetic poles 32 are assembled into a pole one by one into the magnetic pole box pushing frame 8, the hydraulic cylinder one 9 pushes the assembled magnetic poles to the feeding device, and then the magnetic poles are sent to the pushing frame 18 through the lifting and translation of the feeding device, then the hydraulic cylinder two 19 pushes the whole magnetic poles into the rotor rotating frame, completes the magnetic pole pushing of one pole, and then controls the rotation angle of the rotor rotating frame to enter the next cycle.

[0041] The existing vertical and horizontal magnetic pole box pushing device needs to manually rotate the rotor support or adjust the tool position after pushing a magnetic pole to continue pushing the next magnetic pole. This method needs to consume a lot of manpower to complete the magnetic pole box pushing of a rotor, and it is difficult for the artificial alignment of the rotor support or tool to be in place at one time, and the position needs to be adjusted. The magnetic pole group matching device is designed to solve this problem, and the magnetic pole group matching device 2 is arranged below the frame 1 side, the magnetic pole group matching device 2 comprises a base 7, a magnetic pole box pushing frame 8 and a hydraulic cylinder 9, the magnetic pole box pushing frame 8 is arranged on one side above the base 7, the hydraulic cylinder 9 is arranged on the other side above the base 7, the telescopic rod of the hydraulic cylinder 9 is opposite to the center position of the magnetic pole box pushing frame 8, and the magnetic pole box pushing frame 8 is provided with a longitudinal positioning groove 10; during the magnetic pole pushing process, a plurality of single magnetic poles are loaded in the pushing frame in advance, and after being arranged, the hydraulic cylinder 9 is used for pressing (the positioning groove 1 plays a guiding role), and two connecting rods are loaded to form a magnetic pole group, as shown in Figure 3 This method does not need to separately load the magnetic pole box, saves the labor resources, and improves the work efficiency.

[0042] The front end of the magnetic pole box pushing frame 8 is provided with a baffle 26, the baffle 26 is arranged in a baffle groove 27, as shown in Figure 4 The baffle 26 is pressed at the beginning, and the baffle is taken out after the magnetic pole group is matched, so that the matched magnetic pole group is pushed to the loading device.

[0043] The magnetic pole group matching device 2 is two groups, and the two groups of magnetic pole group matching devices 2 are symmetrically arranged relative to the loading device 3, and the loading is interval, so that the efficiency is improved.

[0044] The rotor is composed of a certain number of magnetic pole boxes with completed magnetization, and the assembly process is that the magnetic pole boxes are sequentially assembled to the rotor barrel type inner frame 24 by using a tool. The existing technical scheme adopts manual loading, that is, the magnetic pole box is transferred to the tool by manpower to complete the process step. Since the magnetic pole box has strong magnetism, there is a risk of magnetic pole box adsorption in the process of manually carrying the magnetic pole box. The improved loading device greatly reduces the adsorption risk.

[0045] The improved loading device 3 is as shown in Figure 5As shown, including lifting frame 11, translation frame 12, motor one 13, flat push hydraulic cylinder 14, the lifting frame 11 is vertically arranged on the frame, lifting frame 11 is provided with guide rail one 15, motor one 13 drives the lifting frame up and down, the translation frame 12 is horizontally arranged in the lifting frame 11, the translation frame 12 is connected with guide rail one 15 through the sliding block, the translation frame is provided with horizontal guide rail two 16, the flat push hydraulic cylinder 14 drives the translation frame 12 to move left and right, the guide rail two 16 is provided with a translation trolley 17, when working, the magnetic pole group in the magnetic pole group device 2 has been assembled to the translation trolley 17, the motor one 13 drives the lifting frame to move upwards (flat with the push frame 18), then the flat push hydraulic cylinder 14 drives the translation frame 12 to move forward, the magnetic pole is sent to the push frame 18, then the translation trolley 17 exits, the magnetic pole remains in the push frame 18, through the improvement, the existing technical scheme is replaced by manpower to carry the magnetic pole box, and the risk of magnetic pole box adsorption is greatly reduced.

[0046] The whole pole pushing device 4 is arranged above the frame 1, the whole pole pushing device 4 is arranged on one side of the feeding device 3, and the whole pole pushing device comprises a push frame 18 and a hydraulic cylinder two 19. Figure 6 As shown, when the magnetic pole group is sent to the push frame 18 during working, the lengthened hydraulic pushing device (hydraulic cylinder two 19) is used in cooperation with the whole pole guiding device (rail three 20), the distance between the whole pole guiding device and the rotor support is increased, the whole pole assembly of the rotor magnetic pole is realized, so that the hydraulic rod only needs to complete a complete pushing process during the magnetic pole pushing process of each pole of the rotor, and the pushing efficiency is greatly improved.

[0047] The present application is provided with a limiting plate 28 at the front end of the push frame 18. Figure 6 And 7 As shown, in the pushing installation process, the magnetic pole can be moved forward along the defined route, and the longitudinal positioning groove two 25 is arranged on the circumferential surface of the cylindrical inner frame 24, which plays a guiding role and ensures that the magnetic pole is smoothly installed.

[0048] In the prior art, the vertical magnetic pole box pushing device pushes the method for placing the rotor support vertically, placing the tool in place and fixing it, first placing the magnetic pole box lower end magnetic pole box pressing plate, installing the square screw rod and other positioning guide components. Then push in the magnetic pole box in turn, while installing the radial bolt or limiting block and other fastening parts, after the whole magnetic pole box pushing is completed, install the remaining parts and tighten the torque; the horizontal magnetic pole box pushing assembly device is placed on the rotor support table in the horizontal state of the rotor support, the magnetic steel pressing plate is placed, then all the magnetic pole boxes are pushed in turn according to the specified order in the drawing, the limiting plate or the radial bolt and other fastening parts are installed, and finally the specified position is welded and other finishing work is carried out. The two prior art solutions have the problem of low efficiency for larger magnetic pole boxes. The present application greatly increases the efficiency of the rotor magnetic pole pushing (from one by one installation to one group direct installation) by improving the magnetic pole box pushing method.

[0049] The pushing and placing frame 18 is arranged on the guide rail three 33 of the frame, can adjust the position up and down, and is suitable for installing rotor magnetic poles of different diameters.

[0050] After the installation of one magnetic pole is completed, then the rotor rotating frame (cylindrical inner frame 24) is rotated by a certain angle to enter the next cycle. The rotating device is driven by a servo motor, is connected with the rotor dummy shaft through a shaft coupling, and has rotating function and angle alignment function.

The two groups of rotor support frames 6 are arranged side by side on the base frame 21. The rotating shaft 23 is horizontally arranged at the two ends of the two groups of rotor support frames 6. The motor three 22 is connected with the rotating shaft 23. The cylindrical inner frame 24 is horizontally fixed on the rotating shaft 23. The axis of the rotating shaft 23 is parallel to the direction of the track three 20. The upper edge of the cylindrical inner frame 24 is flush with the track three 20.

The motor one, the hydraulic cylinder, the motor three and other electric devices are connected with the electric control box.
