[0028] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] An embodiment of the present application provides a generator magnetic pole shaping device, which can solve the problem of low qualification rate of generator magnetic pole manufacturing in related technologies.

[0030] See also Figures 1 to 4 , a generator magnetic pole shaping device, comprising:

[0031] A base 1 is provided with a mounting structure 2, which includes a plurality of chambers 21, and an opening on one side of the chamber 21 for inserting the legs;

[0032] The extrusion plate 3 is disposed opposite to the chamber 21 and can be moved away from or closer to the base 1;

[0033] When the support leg is located in the chamber 21 , the extrusion plate 3 approaches the base 1 , and the extrusion plate 3 squeezes the support leg;

[0034] In this embodiment, the extrusion plate 3 can be controlled to rise and fall vertically by a hydraulic press;

[0035] In this embodiment, the internal structure of the chamber 21 is manufactured according to the standard of the generator pole legs. The number of the chambers 21 is seven, and the seven chambers 21 correspond to the seven legs of the generator pole blank, respectively. Therefore, the positions of the seven chambers 21 need to meet the requirements. The seven legs of the generator pole blank are inserted into the seven chambers 21 from the opening. After the seven legs are inserted into the chambers 21, the generator pole blank is pressed by the extrusion plate 3, so that the legs of the generator pole blank are tightly attached to the chamber 21, and the chamber 21 squeezes the legs, thereby achieving the purpose of shaping the legs through the chamber 21.

[0036] The mounting structure 2 further includes a receiving platform 22, a screw rod 25, and a screw sleeve 26;

[0037] The receiving platform 22 is slidably connected to the mounting structure 2, the screw 25 is connected to the base 1, the screw 25 is threadedly connected to the screw sleeve 26, and the screw sleeve 26 is connected to the receiving platform 22;

[0038] like Figure 2As shown, a cylindrical groove is provided on the upper end surface of the base 1, the mounting structure 2 is located in the cylindrical groove, and the chamber 21 is provided at the bottom of the cylindrical groove to prevent the chamber 21 from being located on the surface of the base 1 and causing accidental wear at the opening of the chamber 21. A sliding groove for the screw sleeve 26 is provided on the bottom of the cylindrical groove. The screw sleeve 26 cannot rotate in the sliding groove. One end of the screw sleeve 26 is connected to the receiving platform 22, and the screw rod 25 is rotatably connected to the screw sleeve 26. The screw sleeve 26 is driven to rise and fall in the sliding groove by the rotation of the screw rod 25, thereby causing the screw sleeve 26 to drive the receiving platform 22 to rise and fall.

[0039] Manually placing the legs of the generator pole blank into the chamber 21 requires the staff to align the legs with the chamber 21 from top to bottom, which is rather troublesome. In this application, before shaping the generator pole, it is necessary to first raise the receiving platform 22 by rotating the screw, and the receiving platform 22 extends out of the cylindrical groove. The generator pole blank is placed on the receiving platform 22, and then the receiving platform is controlled by rotating the screw to insert the legs of the generator pole blank into the chamber 21.

[0040] The base 1 is provided with an engaging groove 4;

[0041] The fitting groove 4 matches the receiving platform 22, and the receiving platform 22 can be inserted into the fitting groove 4;

[0042] Since the generator pole rough blank is on the receiving platform 22, in the absence of the interlocking groove 4, the receiving platform 22 will eventually be close to the bottom of the cylindrical groove, and there will be a gap between the legs of the generator pole rough blank and the chamber 21. Therefore, an interlocking groove 4 is provided at the bottom of the cylindrical groove. When the receiving platform 22 with the generator pole rough blank placed thereon descends, the receiving platform 22 will eventually be interlocked into the interlocking groove 4. At this time, the legs of the generator pole rough blank will be close to the inner wall of the chamber 21, which is convenient for the subsequent extrusion plate 3 to press the generator pole rough blank.

[0043] A plurality of limiting members 23 are provided on the receiving platform 22;

[0044] A plurality of limiting members 23 are arranged circumferentially around the edge of the extrusion plate 3, and there is a limiting space between every two limiting members 23 for clamping the main support leg;

[0045] The receiving platform 22 is provided with a number of bosses 24;

[0046] A plurality of bosses 24 are circumferentially arranged around the center of the receiving platform 22, and the bosses 24 can be closely attached between two adjacent legs;

[0047] In the present application, the receiving platform 22 is a cylindrical structure. A rectangular limiting member 23 is provided on the edge of the receiving platform 22. Every two limiting members 23 clamp a support leg to form a preliminary limit for the rough magnetic pole blank of the generator. A boss 24 is provided above each limiting member 23. In the present application, the space between the two support legs is arc-shaped, so the surface of the boss 24 facing the center of the receiving platform 22 is arc-shaped, and the boss 24 can perfectly fit the connection between the two support legs.

[0048] It should be noted that when the receiving platform 22 is located in the fitting groove 4, the limiting member 23 is also located in the fitting groove 4;

[0049] When placing the generator pole blank on the receiving platform 22, the legs of the generator pole blank need to face downward, and the bottom of the disc of the generator pole blank should be fitted with the receiving platform 22. The legs are located between the two limit members 23, and the boss 24 fits the connection between the two legs. The generator pole blank is fixed on the receiving platform 22, and the receiving platform 22 is subsequently lowered, and the legs are inserted into the chamber 21. At the same time, it is convenient to place the generator pole blank on the receiving platform 22.

[0050] The mounting structure 2 further includes a drive rod 27;

[0051] The driving rod 27 is rotatably connected to the base 1 and is used to drive the screw rod 25;

[0052] In this application, if Figure 2 As shown, the driving rod 27 and one end of the screw rod 25 are both provided with bevel gears, and the two bevel gears are engaged with each other. The driving rod 27 extends from the inside of the base 1 to the outside of the base 1, which makes it convenient to drive the screw rod 25 to rotate by controlling the driving rod 27, and makes it convenient for the staff to operate the driving rod 27 to control the lifting and lowering of the receiving platform 22.

[0053] Here's how this application works:

[0054] Before shaping, the present application needs to first drive the receiving platform 22 to rise from the cylindrical groove on the upper end surface of the base 1 by controlling the driving rod 27, and then place the generator pole rough blank on the receiving platform 22, and the generator pole rough blank support foot is located between the two limit members 23, and the boss 24 is in contact with the connection between the two generator pole rough blank support feet. Then, the receiving platform 22 is controlled to descend by the driving rod 27, and finally the receiving platform 22 and the limit member 23 are located in the interlocking groove 4, and the generator pole rough blank support foot is inserted into the cavity 21, and the support foot is close to the cavity 21. At this time, the extrusion plate 3 is controlled to descend by the hydraulic press to squeeze the generator pole rough blank so that the inner wall of the cavity 21 squeezes the generator pole rough blank support foot and aligns it for shaping.
