Magnetic shoe is the tile that is applied to have on the motor magnetic, is to make by rare earth material die casting and through grinding, through the formation magnetic shoe that magnetizes.The magnetic shoe of rotor generally is fixed on the rotor core by binding agent, and this kind magnetic shoe fixed structure in use causes magnetic shoe to come off through regular meeting because of factors such as ageing of binders or machine operation heatings.
The utility model content
The technical problems to be solved in the utility model is: a kind of novel motor magnetic tile fixture is provided, has strengthened the fastening performance in location of magnetic shoe greatly, also reduced the step of assembling simultaneously, improved operating efficiency.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of fixture of motor magnetic tile, comprise magnetic core, magnetic shoe, casing and fixture, described magnetic shoe is arranged at the skin of magnetic core, described casing is arranged at the skin of magnetic shoe, be provided with the gluing articulamentum between described magnetic shoe and the magnetic core, be connected by dowel fixes between described magnetic shoe and the casing, described fixture comprises magnetic shoe folder and fixed head, surely connect by the magnetic shoe clamping between the described magnetic shoe, described fixed head is arranged at the magnetic core both sides, connects by rivet between the described fixed head.
According to another embodiment of the present utility model, a kind of fixture of motor magnetic tile comprises that further described fixed head edge bends inwards, and fixedlys connected with magnetic shoe with casing in the edge of described bending.
According to another embodiment of the present utility model, a kind of fixture of motor magnetic tile further comprise be provided with between the described fixed head heat radiation gap.
According to another embodiment of the present utility model, the mode of fixedlying connected between a kind of fixture of motor magnetic tile further comprises described magnetic shoe and magnetic shoe presss from both sides is an interference fit.
According to another embodiment of the present utility model, a kind of fixture of motor magnetic tile comprises that further described magnetic shoe folder is provided with perforate, and described perforate size matches with the pin size.
The utility model has solved the defective that exists in the background technology, adopt gluing that magnetic shoe is fixed in vertical direction, the fixed head that bends inwards by the edge on the circumferencial direction is magnetic shoe fixedly, in addition, also be connected surely between magnetic shoe and the magnetic shoe, so, make the fastening performance in location of magnetic shoe strengthen greatly by the magnetic shoe clamping, also reduce simultaneously the step of assembling, improved operating efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view.
Wherein: 1, magnetic core, 2, magnetic shoe, 3, casing, 4, the gluing articulamentum, 5, pin, 6, the magnetic shoe folder, 7, fixed head, 8, rivet, 9, the edge.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The fixture of a kind of motor magnetic tile shown in Fig. 1-2, comprise magnetic core 1, magnetic shoe 2, casing 3 and fixture, described magnetic shoe 2 is arranged at the skin of magnetic core 3, described casing 1 is arranged at the skin of magnetic shoe 2, be provided with gluing articulamentum 4 between described magnetic shoe 2 and the magnetic core 3, fixedly connected by pin 5 between described magnetic shoe 2 and the casing 1, described fixture comprises magnetic shoe folder 6 and fixed head 7, press from both sides 6 fixedly connected between the described magnetic shoe 2 by magnetic shoe, described fixed head 7 is arranged at the magnetic core both sides, connects by rivet 8 between the described fixed head 7.
As shown in Figure 2, because the edge 9 of fixed head 7 bends inwards, fixedly connected with magnetic shoe 2 with casing 1 in the edge 9 of this bending, and the concrete edge that is connected to this bending 9 is by fixedlying connected with magnetic shoe 2 with being connected further of casing 1.This fixed head 7 adopts the metalwork identical or close with the core material thermal coefficient of expansion simultaneously, when the motor rotary temperature changes, fixed head 7 also can be reliably fixing magnetic shoe 2; In addition, also be provided with the heat radiation gap between the fixed head 7, it makes the heat dispersion of motor improve, and further the fixed performance of magnetic shoe 7 is consolidated.
