Abstract
The utility model belongs to the technical field of a tooling, in particular to a motor rotor overlapping punching sheet tooling, which comprises an upper mold and a lower mold, wherein the upper mold is characterized in that a plurality of sections of step-shaped cylindrical holes matched with the diameter of one end of a rotating shaft of a motor rotor are axially arranged on a cylinder with the outer diameter smaller than the outer diameter of a motor rotor punching sheet, the lower mold comprises a base and a guide block, the base is a hollow cylinder, an inner hole of the cylinder is a cylindrical hole matched with the diameter of the other end of the rotating shaft of the motor rotor, more than two arc-shaped through holes which are in axial arrangement and are matched with circular arc sections of grooves uniformly distributed on the outer cylindrical surface formed by the motor rotor punching sheet are uniformly distributed on the base, a guide block matched with the arc-shaped through holes is arranged in the arc-shaped through holes, and one end of the guide block extends out of the base. The motor rotor overlapping punching sheet tooling has the advantages that the positioning is precise, the sheet staggering of the rotor punching sheet can not occur, and the rotor cylindricity is high after the press mounting.
Description
Technical field:
The utility model belongs to the frock technical field, refers in particular to a kind of rotor and laminates the punching frock.
Background technology:
The structure of rotor forms for be arranged with the some punchings that laminate mutually outside rotating shaft.In the rotor punching lamination process, phenomenon such as be easy to generate that wrong sheet or rotor punching tilt or cylindricity is low and influence the quality of rotor even cause motor to be scrapped has reduced rate of finished products, has improved production cost.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, when press-fiting rotor punching can wrong sheet, press-fit the high rotor of back rotor cylindricity and laminate the punching frock.
The utility model is achieved in that
Rotor laminates the punching frock, comprise patrix and counterdie, described patrix is that external diameter is less than axially offering the notch cuttype cylindrical hole that plurality of sections can match with the diameter of motor rotor shaft one end on the cylinder of motor rotor punching sheet external diameter, described counterdie comprises base and guide pad, base is the cylinder of a hollow, the cylindrical hole of this cylindrical endoporus for matching with the other end diameter of motor rotor shaft, axially be provided with being evenly equipped with on the base more than two, the arc-shaped through-hole that matches with the arc section of groove uniform on the external cylindrical surface that motor rotor punching sheet forms, be provided with guide pad with matching in arc-shaped through-hole, an end of guide pad extends outside the base.
Corresponding to all radially offering screwed hole vertically that arrange, that be connected with arc-shaped through-hole more than on the external cylindrical surface at each arc-shaped through-hole place, in screwed hole, be provided with the adjustment screw that can be used to regulate the guide pad position on the above-mentioned counterdie.
Above-mentioned screwed hole is two.
Above-mentioned arc-shaped through-hole and guide pad with matching are two or three or four or five or six or seven or eight.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is made up of patrix and counterdie, and is simple in structure, easy to use;
2, the adjustment screw that is provided with on the external cylindrical surface of the utility model counterdie can be regulated the guide pad position by holding out against guide pad, can prolong the useful life of frock;
3, the utility model location accurately, rotor punching can wrong sheet when press-fiting, and press-fits back rotor cylindricity height.

Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1-6:
Rotor laminates the punching frock, comprise patrix 10 and counterdie 20, described patrix 10 axially offers the notch cuttype cylindrical hole 102 that plurality of sections can match with the diameter of motor rotor shaft one end 302 on the cylinder 101 of external diameter less than the external diameter of motor rotor punching sheet, described counterdie 20 comprises base 201 and guide pad 202, base 201 is the cylinder of a hollow, the cylindrical hole 2013 of this cylindrical endoporus for matching with the other end diameter of motor rotor shaft, axially be provided with being evenly equipped with on the base 201 more than two, the arc-shaped through-hole 2012 that matches with the arc section 301 of groove uniform on the external cylindrical surface that motor rotor punching sheet forms, in arc-shaped through-hole 2012, be provided with guide pad 202 with matching, outside the one end protuberate basic unit 201 of guide pad 202, and the height of its extension is higher than the thickness that laminates of motor rotor punching sheet.
On the above-mentioned counterdie 20 corresponding to all radially offering two screwed holes 2011 vertically that arrange, that be connected with arc-shaped through-hole 2012 on the external cylindrical surface at each arc-shaped through-hole 2012 place, be provided with the adjustment screw 2014 that can be used to regulate guide pad 202 positions in screwed hole 2011, adjustment screw 2014 holds out against the position that fixes guide pad 202 with guide pad 202.
Above-mentioned arc-shaped through-hole 2012 and guide pad with matching 202 are two, it also can be three or four or five or six or seven or eight, cooperate patrix 10, base 201 to locate stator punching, rotor punching can wrong sheet when press-fiting, and press-fits back rotor cylindricity height.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection range of the present utility model.
