Abstract

The utility model discloses a hybrid stepping motor rotor sheet overlying tool, and belongs to the technical field of tools. The overlying tool comprises a tool base and an upper pressure head, a positioning mandrel matched with a central hole of a rotor sheet is fixed onto the tool base, a mandrel sleeve hole is arranged on the upper pressure head, the diameter of the mandrel sleeve hole is larger than that of the positioning mandrel, at least two baffle plates are fixed onto the tool base, a movable positioning insert is inserted into each baffle plate, and an inserting portion matched with an inter-tooth space of the rotor sheet in contour is arranged at the head end of the positioning insert. The hybrid stepping motor rotor sheet overlying tool is simple in structure, the rotor sheet is accurately positioned, and overlying quality can be ensured.

Description

The laminating tool of composite stepper motor rotor punching
Technical field
The utility model relates to a kind of laminating tool of composite stepper motor rotor punching, belongs to the frock technical field.
Background technology
At present, the composite stepper motor rotor core is to be overrided to form by a plurality of rotor punchings, and one week of composite stepper motor rotor punching external diameter is uniform-distribution with the little tooth of same widths, must guarantee the perpendicularity of little tooth in the process that rotor punching laminates.So in the lamination process of rotor punching, cause easily the phenomenons such as rotor punching inclination or cylindricity are low, it is bad that rotor punching laminates rear little tooth linearity, and affect quality of rotor of motor, can not guarantee motor performance, and cause motor performance not up to standard, reduce rate of finished products.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provide a kind of simple in structure, to the rotor punching registration, can guarantee to laminate the laminating tool of the composite stepper motor rotor punching of quality.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of laminating tool of composite stepper motor rotor punching, comprise tooling base and seaming chuck, be fixed with the positioning core axle that can cooperate with the rotor punching centre bore on the tooling base, have the diameter mandrel trepanning larger than positioning core axle diameter on the seaming chuck, be fixed with at least two baffle plates on the tooling base, all be fitted with on each baffle plate and movably locate plug-in unit, the head end of location plug-in unit is provided with the insertion section that the profile with the rotor punching inter-tooth slots matches.
Further, have the rotor boss on the described tooling base, and the rotor boss is between baffle plate.
After having adopted technique scheme, the engagement limits of positioning core axle and tooling base five degrees of freedom of rotor punching, and the location plug-in unit at least two baffle plates has limited the another one degree of freedom of rotor punching, so just limited the six-freedom degree of rotor punching, in the frock process, the location plug-in unit is directly to be inserted in the inter-tooth slots of rotor punching, and positioning accuracy is fairly good, and rotor punching also is not easy to tilt, and can guarantee the quality that the composite stepper motor rotor punching laminates; The rotor boss can cooperate with the bottom of rotor better, and the rotor boss can utilize grinding machine to grind certain flatness, and positioning accuracy is higher like this.

Fig. 1 is the stereogram of the laminating tool of composite stepper motor rotor punching of the present utility model;
Fig. 2 is the front elevational schematic of the laminating tool of composite stepper motor rotor punching of the present utility model;
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
Shown in Fig. 1 ~ 3, a kind of laminating tool of composite stepper motor rotor punching, comprise tooling base 5 and seaming chuck 6, be fixed with the positioning core axle 4 that can cooperate with rotor punching 3 centre bores on the tooling base 5, have the diameter mandrel trepanning 6-1 larger than positioning core axle 4 diameters on the seaming chuck 6, be fixed with two baffle plates 2 on the tooling base 5, all be fitted with on each baffle plate 2 and movably locate plug-in unit 1, the head end of location plug-in unit 1 is provided with the insertion section 1-1 that the profile with rotor punching 3 inter-tooth slots 3-1 matches.The engagement limits of positioning core axle 4 and tooling base 5 five degrees of freedom of rotor punching 3, and the location plug-in unit 1 on two baffle plates 2 has limited the another one degree of freedom of rotor punching 3, so just limited the six-freedom degree of rotor punching 3, in the frock process, location plug-in unit 1 is directly to be inserted in the inter-tooth slots 3-1 of rotor punching 3, positioning accuracy is fairly good, and rotor punching 3 also is not easy to tilt, and can guarantee the quality that the composite stepper motor rotor punching laminates.
For tooling base 5 can be cooperated with the bottom of rotor better, as shown in Figure 1, 2, have rotor boss 5-1 on the tooling base 5, and rotor boss 5-1 is between baffle plate 2.Rotor boss 5-1 can utilize grinding machine to grind certain flatness, and positioning accuracy is higher like this.
Operation principle of the present utility model is as follows:
The rotor punching 3 of some is enclosed within on the positioning core axle 4, then the location plug-in unit 1 on the baffle plate 2 is inserted in the inter-tooth slots 3-1 of rotor punching 3, rivet is put into first the rivet hole 3-2 of rotor punching 3, then utilize seaming chuck 6 rivet to be pressed in the rivet hole 3-2 of rotor punching 3, such rotor core just machines.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
