Abstract
A claw pole blank structure of a claw pole type generator with permanent magnet mounting grooves is characterized in that a permanent magnet fixing protrusion blank is arranged on the bottom surface of a base between each claw pole of a claw pole and a magnetic yoke portion and close to the root of each claw pole, the permanent magnet mounting grooves are formed in the side portions of the claw poles, and inclined planes are arranged on the inner sides of the claw poles. The method has the advantages that the claw pole blank with the permanent magnet mounting groove and the inner side magnetic steel fixing protrusion is forged firstly, then a part of the protrusion blank is turned off through machining, and the rest part forms a magnetic steel fixing thin-wall structure. The claw pole of the permanent magnet mounting groove structure with the thin-wall structure meeting the requirement of permanent magnet mounting can be processed by one-time clamping, the processing time is shortened to 20 seconds from the original 20 minutes, the processing efficiency is improved, and the service life of the die is prolonged from the original 3000 to the present 5000.
Description
Technical Field
The utility model relates to a take claw utmost point formula generator claw utmost point blank structure of permanent magnet mounting groove is suitable for the claw utmost point formula generator of various permanent magnets of taking.
Background
Along with the diversified miniaturization of automobile engines, the engine structure is more and more compact, requires claw pole type generator size to be more and more little, and the generated energy is more and more high. In order to meet the requirements, in order to improve the low-speed power generation amount of the generator, permanent magnets are arranged on the claw poles. Traditional generator installation permanent magnet claw utmost point preparation mode has two kinds, and the first kind is in the claw utmost point side, processes out the groove of 12 claw utmost point sides through milling cutter, and this kind of claw utmost point processing cutter requires frequent change position, and processing technology is complicated, and the installation location requires accurately, and permanent magnet mounting groove process time is long, and every claw utmost point milling flutes needs about 15~20 minutes, and production efficiency is not high. The second is directly forged the magnet steel mounting groove on the claw utmost point, because the inside excitation coil that needs equipment of claw utmost point, must have sufficient space, this has just caused the magnet steel standing groove inboard only a very little thin wall, because the claw utmost point blank belongs to the hot forging, and the shape can't be guaranteed in the drawing of patterns during the forging, can guarantee that the shape is cut the claw utmost point mould life-span that directly forges out the location thin wall and is short, only can beat about 3000 probably.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned current problem that exists, provide a take claw utmost point formula generator claw utmost point blank structure of permanent magnet mounting groove.
The utility model discloses a realize like this: the bottom surface of the base between each claw of the claw pole and the magnetic yoke part is provided with a permanent magnet fixing bulge blank close to the root of the claw, the side part of the claw pole is provided with a permanent magnet mounting groove, and the inner side of the claw is provided with an inclined plane.
The utility model has the advantages of, it is complicated to have solved traditional installation permanent magnet claw utmost point processing permanent magnet mounting groove technology, and the problem that processing time is long or direct forging takes magnet steel mounting groove claw utmost point mould life-span to be short. Firstly forging a claw pole blank with a permanent magnet mounting groove and an inner side magnetic steel fixing bulge, turning off a part of the bulge blank in a machining mode, and forming a magnetic steel fixing thin-wall structure on the rest part. The claw pole with the thin-wall permanent magnet mounting groove structure and meeting the requirement of permanent magnet mounting can be processed by one-time clamping, the processing time is shortened, the processing efficiency is improved, the manufacturing cost is saved, the service life of a forging die is prolonged, and the like. Compared with the groove milling process, the processing time is shortened to 20 seconds from the original 20 minutes. Compared with a directly forged die, the service life of the die is prolonged from 3000 original dies to 5000 current dies.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the finished claw pole after processing.
Detailed Description
The following detailed description is made with reference to the accompanying drawings: as shown in the figure, basic bottom surface 2 between every utmost point claw 1 and the yoke portion 7 of claw utmost point is close to the utmost point claw root and is equipped with fixed protruding blank 3 of permanent magnet, the lateral part at utmost point claw 1 of claw utmost point is equipped with permanent magnet mounting groove 4, utmost point claw 1 inboard is equipped with inclined plane 5, the processing of rethread numerical control lathe falls the partly of fixed protruding blank 3 of magnetic steel, it processes to basic bottom surface 2 to follow inclined plane 5 that utmost point claw 1 was equipped with promptly, the lateral part is parallel with the lateral part of permanent magnet mounting groove 4, the remaining part is exactly the fixed thin wall 6 of magnet steel, thereby solve the fixed thin wall 6 problem that forges difficult mould life-span of. The processing time that the processing center needs to process twelve positions for directly milling the magnet fixing groove is shortened, and the production efficiency is improved.
