BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generator mounting technology field, and more particularly to a magnet steel supply device.

The generator rotor of the permanent magnet wind power generator set is generally fixed to the magnet steel and the magnet steel is fixed to the inner yoke wall of the rotor. Conventionally, such magnet steel is generally fixedly attached to the inner wall of the magnetic yoke by a full infusion method. However, as the wind turbine generator set becomes larger and larger, the magnet steel is fixed in a generally mechanically fixed manner in consideration of the fixed quality and the reliability of the generator set. As shown in FIG. 1, FIG. 1 shows a three-dimensional structure of a rotor to which a magnet steel is fixed. For convenience of illustration, only a partial structure is shown in the drawing, A plurality of second magnet bars 2 are installed on the inner wall 11 in a generally vertical direction and a plurality of screw holes are formed in the inner wall 11 of the magnetic yoke. (21) and through these screw holes to the magnetic yoke inner wall (11). The magnet steel 3 is installed between the second magnet steel stands 2 and the magnet steel 3 absorbs the magnetic yoke inner wall 11 while both sides are pressed by the second magnet steel stall 2. The two sides of the second magnet steel bin 2 are inclined and the space between the sides of the two adjoining second magnet steel bin 2 constitutes a dovetail groove mold cavity and the magnet steel 3 is directly connected to the dovetail groove mold cavity Located. As shown in Fig. 2, the cross section of the magnet steel 3 is a dovetail shape fitted to the dovetail groove mold cavity, and both side surfaces of the magnet steel 3 are inclined surfaces, and the magnet steel 3 does not fall off because it meets the inclined surface of the stand. The number of the magnet steel 3 is plural (only one of which is shown by way of example in Fig. 1). In order to facilitate the processing of the magnetic yoke inner wall 11 in manufacturing the rotor, a generally stepped surface 12 is provided below the magnetic yoke inner wall 11 on the rotor 1, The inner diameter of the yoke inner wall 11 is larger than the inner diameter of the yoke inner wall 11 and no magnet steel is mounted on the stepped surface 12 and the stepped surface 12 has a constant width even in the vertical direction.

As shown in Figs. 3 and 4, in this embodiment, the number of supply grooves 51 provided in the supply stage 5 is four, and simultaneously, through the four supply grooves 51, The magnet steel can be supplied for the purpose of improving the production efficiency. The magnet steel is vertically placed in the feed groove 51, which means that the dovetail-shaped cross section of the magnet steel and the groove bottom of the feed groove 51 are parallel to each other, that is, in a plan view or a bottom view, Is a dovetail type. In the embodiment of the present application, the shape of the magnet steel is a dovetail shape, which indicates a shape or a similar shape as shown in FIG. 2, that is, a cross section has a narrower overall shape and a wider shape, and a dovetail- ). ≪ / RTI > The width of the feed groove 51 is slightly larger than the width of the vertically placed magnet steel so that the magnet steel can be slid in the feed groove 51 and the feed groove 51 is formed in the longitudinal direction of 3 to 3.5 magnet steel packets The magnet steel packet can be made to accommodate a length of 5 or 6 magnet steel in general), and the aligned magnet steel is placed vertically in the feed groove 51 during operation.

The arc-shaped panel 71 of the magnet steel guide mechanism 7 forms an arc-like shape and the center of the arc is the center of the rotor 1 in order to blend with the magnetic yoke of the rotor 1, The guide grooves 73 are also arranged in an arcuate shape so that the four supply grooves 51 can be radially distributed as shown in Fig. 5 in order to realize the coupling between the supply grooves 51 and the guide grooves 73 And the center lines thereof are all passed through the center of the rotor 1, and the four supply grooves 51 are individually connected to the four guide grooves, respectively, so that the magnet strength is constantly arcuate, which is advantageous for pushing operation of the magnet steel pushing device.

A transparent cover plate 52 may be further provided on the supply stage 5 at a position close to the engagement portion of the guide groove 73 and the supply groove 51. [ The transparent cover plate 52 covers the four feed grooves 51 and can prevent the operator from causing operational hazards due to interference of the magnet steel mutual adsorption between the adjacent gaps as a magnetic steel guarantee at the front of the feeder apparatus, The operator can also observe the running state of the magnet steel 3 in the four feed grooves 51 through the transparent cover plate 52. [

The material of the feed stage 5 may be 304 stainless steel, which avoids the feed stage 5 from creating an attraction force for the magnet steel and affecting the supply of magnet steel to the magnet steel pushing device.

2. Specific configuration of the magnet steel pushing mechanism (6)

In this embodiment, the number of the pawls 621 is four, and four feed grooves 51 are provided Thereby pushing the magnet steel (3).

The first driving device 61 drives the push plate 62 to guide the pawl 621 to linearly move in the feed groove 51 and push the magnet steel 3 with the pawl 621 in the feed groove 51 . Here, the first driving device 61 may be a cylinder, or may be a mechanism capable of advancing arbitrary linear driving such as a lead screw that is jointly driven by a motor and a speed reducer. The pawl 621 may be made of a non-magnetic adsorbent material, and the non-magnetic adsorbent material referred to herein refers to a material that is not adsorbed by the magnet or a negligible material (e.g., plastic, rubber, etc.) 621 and the magnet steel 3 can be avoided.

Preferably, the pawl 621 is an elastic wheel. The movement of the four pawls 621 in the four feed grooves 51 is synchronous linear motion, in other words, the movement locus of the four pawls 621 is parallel, When the four pawls 621 push the magnet steel 3 in four rows, the pawl 621 on both sides and the grooves of the supply grooves 51 on both sides interfere with each other, The pushing force against the magnet steel 3 is not affected because it can continue to move through the elastic deformation itself when the groove 621 comes into contact with the groove wall of the supply groove 51.
