Abstract
The invention relates to the technical field of motors, specifically a tool for laminating tilted-slot stator cores. The tool comprises a body, and the bottom surface of the body is provided with a bottom plate. The top surface of the body is provided with an upper pressure plate. The bottom plate, the body and the upper pressure plate are fixedly connected through tensioning screw rods. The circumferential surface of the body is uniformly provided with a plurality of positioning ribs, and the body is sleeved by iron cores. The inner peripheries of the iron cores are positioned through the positioning ribs. The body is also provided with tilted keys, and the tilted keys cooperate with tilted slots of the iron cores. The tool is simple and reasonable in structure. The tool can easily guarantee the quality of the iron cores and the angles of the tilted slots when the tool is in use, and is high in laminating efficiency.
Description
Technical field
The present invention relates to technical field of motors, specifically a kind of chute stator iron core laminated frock.
Background technology
In threephase asynchronous machine, there is additional torque, this additional torque is to caused by the effect of rotor by high order harmonic component.Adopt the way increasing air gap that the amplitude of high order harmonic component is significantly reduced, but it is subject to the restriction of motor performance, the amplitude of accommodation is limited.Another way adopts iron core chute, and electric machine iron core skewed slot can improve magnetic circuit, weaken high order electromagnetism harmonic wave, thus it is smooth to reach generator waveform, reduces its noise and vibration, reduces the wastage and raises the efficiency.Relative rotor skewed slot, skewed stator slot is because inner diameter volume is little, and exist and laminate difficulty greatly, angle of bevel is wayward.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of chute stator iron core laminated frock, this frock has two reorientations, ensures skewed stator core slot angle, and handled easily person operates, and enhances productivity.
According to technical scheme of the present invention: a kind of chute stator iron core laminated frock, it is characterized in that: comprise body, described body bottom surface is provided with base plate, end face is provided with top board, and base plate, body and top board three are fixedly connected with by stretching screw, and body circumferential surface is uniform arranges some positioning bars, sheathed iron core on described body, described iron core inner circle is located by positioning bar, and body is also provided with taper key, and taper key matches with the skewed slot of iron core.
As a further improvement on the present invention, described positioning bar has four, and described in every root, positioning bar is all anchored on body by soket head cap screw.
As a further improvement on the present invention, described taper key is fixed on body by baffle plate and guide vane end stop.
As a further improvement on the present invention, the centre of gyration of described body is provided with hanging axis.
As a further improvement on the present invention, described taper key is with step, and taper key has angle of inclination.
Technique effect of the present invention is: product structure advantages of simple of the present invention, and operationally, utilize this frock to laminate chute stator iron core, iron core quality and angle of bevel easily ensure, laminate efficiency high; This frock use safety, easy installation and removal.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 4, comprise stretching screw 1, top board 2, body 3, baffle plate 4, iron core 5, positioning bar 6, guide vane end stop 7, taper key 8, base plate 9, hanging axis 10 etc.
As shown in Fig. 1 ~ 4, the present invention is a kind of chute stator iron core laminated frock, comprise body 3, described body 3 bottom surface is provided with base plate 9, and end face is provided with top board 2, base plate 9, body 3 and top board 2 three are fixedly connected with by stretching screw 1, body 3 circumferential surface is uniform arranges some positioning bars 6, sheathed iron core 5 on described body 3, and described iron core 5 inner circle is located by positioning bar 6, body 3 is also provided with taper key 8, and taper key 8 matches with the skewed slot of iron core 5.In the course of the work, positioning bar 6 plays the effect of main location, locates iron core 5 inner circle by positioning bar 6, and taper key 8 plays the effect of secondary location, and taper key 8 ensures the concentricity of iron core 5.
Positioning bar 6 has four, and positioning bar 6 described in every root is all anchored on body 3 by soket head cap screw; Taper key 8 is fixing on the body 3 by baffle plate 4 and guide vane end stop 7; The centre of gyration of body 3 is provided with hanging axis 10; Taper key 8 is with step, and taper key 8 has angle of inclination.
The assembling process of product of the present invention is as follows: base plate 9 is placed in forcing press center, and body 3 is arranged on base plate 9 by stretching screw 1.As shown in Figure 3, positioning bar 6 is installed on the body 3 by soket head cap screw, positioning bar 6 located stator core 5 inner circle, and ensure the concentricity laminating rear stator core 5, meanwhile, positioning bar 6 produces wearing and tearing after a long time use, is convenient to maintain and replace.Taper key 8 is installed on the body 3 by baffle plate 4 and guide vane end stop 7, and as shown in Figure 4, taper key 8, can spacing stator slot shape with step, and taper key 8 angle of inclination can require to manufacture according to core design, can ensure the angle of bevel of stator core 5.After punching is stacked to design height, be pressed on base plate 9 by stretching screw 1 and top board 2 by stator core 5, stator core 5 and laminating tool can integral lifting, facilitate postorder to process stator core 5.
An above-described approximate suitable application area of the present invention, the invention is not restricted to above field.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
