Abstract

The invention discloses a rotor iron core stamped steel pressing ring of a high-pressure three-phase motor. The pressing ring comprises a pressing ring steel plate and a tooth pressing plate; the tooth pressing plate is uniformly welded on the excircle of the pressing ring steel plate; and the tooth pressing plate is integrally formed with the pressing ring steel plate. The pressing ring provided by the invention avoids the influence to an inserted line of the rotor, improves the manufacturing quality of a motor and has a simple structure.

Description

The rotor core punching trim ring of high pressure three phase electric machine

Technical field

The present invention relates to a kind of high pressure three phase electric machine, particularly a kind of rotor core punching trim ring of high pressure three phase electric machine.

Background technology

The rotor core punching trim ring of conventional big-and-middle-sized high pressure three phase electric machine is a circular hole in cutting on a block plate with the Numerical control cutting lathe at present; And the tooth support that equates with rotor punching groove number in steel plate outer circumference portion cutting; Profile of tooth and correction that also must the reconditioning tooth support behind this trim ring blanking; The end face of the whole trim ring of turning, interior circle, chamfering are followed deburring and greasy dirt then, and all process steps finishes the back mopping.Above-mentioned processing technology is complicated, particularly profile of tooth reconditioning, and the waste of material of this trim ring is more, the worker duration, cost is higher.

Summary of the invention

Technical problem to be solved by this invention provides a kind of rotor core punching trim ring of high pressure three phase electric machine, and it has avoided the influence to the rotor rule, improves the motor workmanship, and simple in structure.

For solveing the technical problem, the invention provides a kind of rotor core punching trim ring of high pressure three phase electric machine, it is characterized in that it comprises trim ring steel plate and tooth support, tooth support evenly is welded on the cylindrical of trim ring steel plate, and tooth support and trim ring steel plate become one.

Preferably, the shape of said tooth support is rectangle or isosceles triangle.

Positive progressive effect of the present invention is: the present invention has avoided the influence to the rotor rule, improves the motor workmanship, and simple in structure.

Description of drawings

Fig. 1 is the front view of the rotor core punching trim ring of high pressure three phase electric machine of the present invention.

Fig. 2 is the end view of the rotor core punching trim ring of high pressure three phase electric machine of the present invention.

Embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the present invention that intactly explains.

As depicted in figs. 1 and 2, the rotor core punching trim ring of high pressure three phase electric machine of the present invention comprises trim ring steel plate 1 and tooth support 2, and tooth support 2 evenly is welded on the cylindrical of trim ring steel plate 1, and tooth support 2 becomes one with trim ring steel plate 1.

The manufacture process of the rotor core punching trim ring of high pressure three phase electric machine of the present invention is following: the inside and outside circle of trim ring steel plate is at numerical control cutting machine cutting and blanking; With the end face of lathe turning trim ring steel plate, interior circle and chamfering; On the end face of trim ring steel plate, weld step, tooth support evenly is welded on the cylindrical step of trim ring steel plate, and the good back of welding face work guarantees evenness; Deburring and greasy dirt then, last mopping.

The quantity of tooth support 2 equates that with the quantity of rotor punching groove the shape of tooth support 2 can be different shapes such as rectangle or isosceles triangle.The structure that the present invention does not adopt trim ring steel plate 1 and tooth support 2 to form from the cutting of monoblock steel plate.Trim ring steel plate 1 is the structures that are connected into one after the separate machined with tooth support 2; The rotor core punching trim ring of high pressure three phase electric machine thrust in use reaches requirement; Motor is reliable; The degree of flicking of rotor punching two end tooth portions is no more than the setting of press-loading process, and has avoided the influence of rotor core punching trim ring to the rotor rule, improves the motor workmanship.The rotor core punching trim ring of high pressure three phase electric machine of the present invention simple in structure, processing technology is convenient, and particularly the crudy of tooth support is good, and production efficiency is high, material economy, manufacturing cost reduces.

Though more than described embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these execution modes.Therefore, protection scope of the present invention is limited appended claims.
