The laminating-type punching axle hole positioning plate provided by the utility model is simple in structure and used for multiple purposes. And the punching processing quality can be improved.
Description
Technical field
The utility model relates to motor and decides the rotor punching, especially the positioning disk in the rotor punching course of processing.
Background technology
The rotor punching is as the important spare part of motor internal, and the precision of its crudy plays a part crucial to the performance of motor; Motor that can not specification, the specification of its rotor punching are generally also different, generally speaking, punch process is carried out in rotor punching to different size, need to change the positioner of different size, certainly will affect production efficiency like this, increase production cost and operating personnel's labour intensity; Present positioner is by the central shaft hole location of rotor punching, for the larger rotor punching of external diameter, when punching press, rotor punching will certainly be with certain the fluctuating of having of drift, keyway easily deforms or burr occurs, is difficult to guarantee that the keyway of going out meets specification requirement, and uses the central shaft hole location to require also higher to the level of skill of operation element, in the situation that the rotor punching location is inaccurate, must there be quality problems in the rotor keyway of going out.
The utility model content
The applicant provides a kind of tabletting type punching axis hole positioning disk for above-mentioned shortcoming of the prior art, and it is simple in structure, can one dish multiplex and improve the punching crudy.
The technical scheme that the utility model adopts is as follows:
Tabletting type punching axis hole positioning disk comprises disk body, and the center of described disk body is provided with positioning round orifice; Be provided with installing hole around the positioning round orifice, between installing hole and disk body edge, have lightening hole; Lightening hole is provided with several square openings each other, and square opening is different respectively from the distance at disk body center; The reverse side of disk body has a boss, and the central authorities of boss are provided with circular groove, and positioning round orifice is positioned at the center of groove;
Further technical scheme is as follows:
Installing hole is evenly distributed on positioning round orifice on every side and is symmetrical about positioning round orifice;
Lightening hole evenly distributes and is symmetrical about positioning round orifice;
The specification of keyway is corresponding on square opening and the rotor punching;
The relative dimensions of centering head is consistent on the size of groove and the lathe;
The position dimension of installing hole and quantity are consistent with located in connection hole dimension and quantity on the lathe fixed core head.
The beneficial effects of the utility model are: by at the disk body center positioning round orifice being set, rotor punching is carried out centralized positioning; A plurality of square openings consistent with rotor punching keyway size are set to be realized the different specification size rotor punching is positioned; Realized that a dish is multiplex, and improved crudy and the efficient of punching.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 to Figure 3, the utility model comprises disk body 15, and the center of described disk body 15 is provided with positioning round orifice 2, and the diameter of positioning round orifice 2 is than the slightly larger in diameter of the location heart 9, be beneficial to the dismounting and change of the location heart 9, the size of the location heart 9 is according to the size customization of rotor punching centre bore; Be provided with installing hole 4 around the positioning round orifice 2, installing hole 4 is around positioning round orifice 2 even distributions and about positioning round orifice 2 symmetries, the position dimension of installing hole 4 and quantity are consistent with located in connection hole dimension and quantity on the lathe fixed core head 12, disk body 15 are fixed in the centering 12 of high-speed machine tool by installing hole 4; Have lightening hole 3 between installing hole 4 and disk body 15 edges, lightening hole 3 evenly distributes and about positioning round orifice 2 symmetries, is conducive to alleviate the weight of disk body 15, and is convenient to the anchor clamps clamping and moves; Lightening hole 3 is provided with several square openings 1 each other, square opening 1 is corresponding from the specification that the distance at disk body 15 centers is distinguished keyway on different and square opening 1 and the rotor punching, square opening 1 that can not the position can be used for locating can not specification rotor punching, realize that a dish is multiplex; The reverse side of disk body 15 is provided with boss 5, the central authorities of boss 5 are provided with circular groove 6, positioning round orifice 2 is positioned at the center of groove 6, on the internal diameter size of groove 6 and the lathe in the centering 12 outside dimension of annular boss 16 consistent, guarantee that disk body 15 can fasten in the centering 12.
Mounting means of the present utility model such as Fig. 4:
The first step, will feel relieved by bolt 13 12 is fixed on the high-speed machine tool 14;
Second step is interlocked the annular boss 16 in the groove 6 of disk body 15 and the centering 12, adjusts the horizontal level of disk body, and the location hole in installing hole 4 and the centering 12 on the disk body 15 is alignd respectively, uses soket head cap screw 7 that disk body 15 and centering 12 is fixed;
The 3rd step, the centre bore of rotor punching 17 is cooperated with the location heart 9, location square hole in the 10 insertion rotor punchings 17 of key drift and the square opening 1 on the disk body 15, then with pad 11 and soket head cap screw 8 that key drift 10 is fixing from the below of disk body 15, compress rotor punching 17, prevent that rotor punching 17 from can move up and down at punching course, affects the jet-bedding quality;
The 4th step, when jet-bedding is carried out in the rotor punching 17 of different size, change the location heart 9 and the 1 pair of rotor punching 17 of square opening by can not the position positions according to the concrete specification of rotor punching 17, realize the multiplex purpose of a dish with this, reduce production costs.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection range of the present utility model, can be done any type of modification referring to claim.
