Description
Technical Field
The invention relates to the field of mining motors, in particular to a permanent magnet separation clamping fixture.
Background
In recent years, with the rapid development of power electronic technology, novel control theory and rare earth permanent magnet materials, permanent magnet motors can be rapidly popularized and applied. The permanent magnet motor has the advantages of small volume, low loss, high efficiency and the like. At present, energy conservation and environmental protection are increasingly paid attention to, and development of environment-friendly 'green motors' is important in the market.
The permanent magnet motor provides excitation by the permanent magnet, so that the structure of the motor is simpler, a collecting ring and an electric brush which are easy to cause problems are omitted, the possibility of motor operation is improved, and the efficiency and the power density of the motor are improved because excitation current is not needed and excitation loss does not exist. However, the attraction force between the permanent magnets is large and difficult to separate, and the attracted permanent magnets are broken off by hands in the process of installing the permanent magnets in the rotor slot by an operator, so that the operation is very difficult.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a permanent magnet motor permanent magnet separation mould.
The specific technical scheme is as follows:
a permanent magnet separation mould of a permanent magnet motor is provided with two supports, a base is fixedly arranged between the two supports, a cutter is connected to one side of the base through a stud in a shaft mode, two ends of the stud are fixed through hexagon nuts, the base is further provided with a long hole on one side of the cutter, and a net bag is hung on the long hole; a stop block is arranged on one side of the cutter and above the net bag, and the stop block is fixed with the cutter through a screw; the base is provided with a vertical port for placing the permanent magnet, and the shape of the vertical port and the shape of the permanent magnet are arranged along with the shape.
The bearing surface in the vertical port and the horizontal plane of the base form an included angle of 30-45 degrees.
And a circular groove is arranged at the joint of the two bearing surfaces of the vertical port.
The utility model has the advantages that: the clamping fixture has a simple structure, is convenient to manufacture, can separate the permanent magnet by one operator, is convenient to operate, prevents the permanent magnet from being damaged in the separation process, and saves the production time.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a front view of FIG. 1;
FIG. 3 is a top view of FIG. 1;
fig. 4 is a front view of the base.
Detailed Description
The utility model is described in detail with reference to the drawings, as shown in the figures, a permanent magnet motor permanent magnet separation clamping fixture is provided with two supports 4, a base 3 is fixedly arranged between the two supports, a cutter 1 is coupled on one side of the base through a stud 7, two ends of the stud are fixed through a hexagon nut 6, the base is also provided with a strip hole 13 on one side of the cutter, and a net bag 5 is hung on the strip hole; a stop block 2 is arranged on one side of the cutter, the stop block 2 is arranged above the net bag 5, and the stop block 2 is fixed with the cutter 1 through a screw 10; the base is provided with a vertical port 11 for placing the permanent magnet, and the shape of the vertical port 11 is arranged along with the shape of the permanent magnet.
The bearing surface in the vertical port and the horizontal plane of the base form an included angle of 30-45 degrees, namely alpha is more than 30 degrees and less than 45 degrees.
In order to make the permanent magnet completely abut against the bearing surface, a circular groove 12 is arranged at the joint of the two bearing surfaces of the vertical port;
the device adopts a non-magnetic structure, for example, non-magnetic stainless steel materials can be adopted;
in order to prevent the permanent magnet from being scraped and collided with the vertical port when the permanent magnet is separated, a rubber sheet 8 is arranged on the vertical port;
in order to prevent the cutter 1 from scraping and colliding with the permanent magnet when the cutter is fed, a gasket 9 is arranged on one side of the cutter, which is close to the base 3;
the utility model discloses a theory of operation is: prevent earlier waiting two permanent magnets of separation in bearing perpendicular mouthful department, aim at the lower extreme department of cutter at the butt joint department of two permanent magnets, push down the permanent magnet on the perpendicular mouth after that, use the cutter to cut downwards, the cutter produces shear stress to the permanent magnet in the process of the sword down to separate two permanent magnets, because the magnetic force between two permanent magnets that temporarily separate is great, consequently the permanent magnet of cutter below still can adsorb in the below of dog, remove behind the permanent magnet on the perpendicular mouth, the permanent magnet of cutter below is owing to not receive magnetic force, and drop in the string bag, accomplishes the separation of two permanent magnets so far.
Claims (3)
1. A permanent magnet motor permanent magnet separation mould is characterized in that: the cutting device is characterized in that two supports are arranged, a base is fixedly arranged between the two supports, a cutting knife is connected to one side of the base through a stud in a shaft mode, two ends of the stud are fixed through hexagon nuts, the base is further provided with a strip hole on one side of the cutting knife, and a net bag is hung on the strip hole; a stop block is arranged on one side of the cutter and above the net bag, and the stop block is fixed with the cutter through a screw; the base is provided with a vertical port for placing the permanent magnet, and the shape of the vertical port and the shape of the permanent magnet are arranged along with the shape.
