Abstract
The invention discloses a magnet leading-in groove tool. The magnet leading-in groove tool comprises a locating permanent magnet and a groove body. A locating groove is formed in the top of the groove body, an attraction area is arranged on the side face of the groove body and a leading-in area is arranged on the lower portion of the groove body. The locating permanent magnet is placed inside the locating groove. The magnet leading-in groove tool realizes the function of recognizing magnet poles easily according to the principle of mutual attraction and repulsion of the magnet poles, improves the working efficiency and lowers the reject ratio.
Description
Technical field
The present invention relates to the frock in a kind of magneto manufacturing process, particularly the magnet lead-in groove frock in a kind of permanent magnet assembling.
Background technology
Magneto is high with its power density, and power factor and efficiency parent higher and that have the wider advantages such as range of operation to be subject to vast motor user compared with induction machine look at.Because this body structure is limit, the permanent magnet technique that magnetizes after assembling completes is more difficult, and therefore charging permanent magnet cartridge rotor manufacturing process has been the subject matter of each factory's production efficiency of restriction and qualification rate always.
Because charging permanent magnet has very strong magnetic, in manufacturing process, ferromagnetism is brought the difficulty of many processing technologys.Consider production efficiency and simplified manufacturing technique, need to make relevant tool supplement production.For preventing that frock and permanent magnet absorption from causing, manufacture difficulty, frock material can not possess magnetic conductivity, considers the quality of frock own and cost simultaneously, considers Hou，Wo company this time fabricating tools employing aluminum material.
It is reported, most of colleague, in manufacturing permagnetic synchronous motor process, all adopts and manually permanent magnet is filled in magnetic groove.Before this, the existing permanent magnet of my company enters groove technique and continues to use direct craft always and enter groove, with workman's identification permanent magnet N/S extremely after, according to permanent magnet magnetic polarity and the pole design of motor own, fill in accordingly that to fill up the Cao Zhong，Wo company existing product number of poles of epoxy resin few, every utmost point permanent magnet quantity is more, in manufacture process, very easily magnet steel is filled less or polarity is counter fills, cause the rising of rotor fraction defective and cost.The defective workmanship that present stage is main and deficiency:
1. workman is not easy the identification permanent magnet N/S utmost point, easily occurs that polarity is anti-loaded, causes motor defective;
2. workman clogs permanent magnet by hand, and inefficiency causes manufacturing cost to rise.
Summary of the invention
Goal of the invention: the object of the invention is in order to solve the deficiencies in the prior art, a kind of magnet lead-in groove frock that can accelerate to clog magnetic pole permanent magnet speed is provided.
Technical scheme: in order to realize above object, a kind of magnet lead-in groove frock of the present invention, comprising: location permanent magnet, cell body; Described cell body top is provided with location notch, and side is provided with adsorption zone, and below is provided with Lead-In Area; Described location permanent magnet; Described location permanent magnet is positioned in location notch.
Magnet lead-in groove frock of the present invention also comprises: for the alignment pin of cell body location.
Described in the present invention, locating permanent magnet is one group, is fixed on the top of location notch; The shape of the rotor that the number of described location permanent magnet and position can be filled is as required determined.
Magnet lead-in groove frock of the present invention is placed a location permanent magnet at cell body top, guarantee that location permanent magnet is placed in place, rotor magnetic pole center, its N/S extremely can be any, by magnetic pole permanent magnet, according to magnetic, there is a natural attraction between the sexes, the principle of same sex mutual exclusion is adsorbed in frock, has so just solved the problem of the N/S utmost point of identification magnetic pole permanent magnet; Grooved and the punching grooved of due to frock, placing magnetic pole permanent magnet are measure-alike, in assembling process, alignment pin is inserted to rotor and carry out positioning tool, and assurance frock can not rotated in assembling magnetic pole permanent magnet process, prevent that magnetic pole is counter to be filled because frock skew causes.
Cell body described in the present invention adopts non-magnetic aluminum material, has avoided production process to occur assembling difficulty.
A method of work for magnet lead-in groove frock, concrete steps are as follows:
(A) according to location permanent magnet pole orientation with insert the principle that permanent magnet magnetizing direction should be consistent, location permanent magnet is positioned in the location notch of cell body top;
(B) then cell body is fixed on to the top of the rotor that magnetic pole permanent magnet need to be installed; The Lead-In Area of cell body and mandrel top offset, and described alignment pin is inserted in location cell body in rotor; Cell body bottom is connected with mandrel;
(C) according to magnetic, there is a natural attraction between the sexes; the principle of same sex mutual exclusion, magnetic pole permanent magnet to be installed clings to adsorption zone surface, after determining and there is no magnetic mutual exclusion; along adsorption zone, gently magnetic pole permanent magnet is entered in rotor, till with flat copper rod, permanent magnet being shifted onto and can not be continued to promote;
(D) after all rotor except the slotting rotor of alignment pin are filled up, fastening screw taken out and keep its invariant position, as step (C), magnetic pole permanent magnet being inserted in the slotting rotor of alignment pin, completing magnetizing of whole rotor.
Beneficial effect: magnet lead-in groove frock of the present invention has the following advantages:
1, magnet lead-in groove frock of the present invention has improved operating efficiency, former every same model rotor is clogged the required time of magnetic pole permanent magnet at 5-8 minute, adopt after magnet lead-in groove frock, every deadline is brought up to 3-4 minute, production efficiency has been improved to 50%, and labor hour cost is obvious;
2, after employing magnet lead-in groove frock, the disqualification rate of product reduces greatly; When disqualification rate is not used frock by original 14%() drop to 3.6%, reduced manufacturing cost.
