Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
As shown in Figures 1 to 5, Stator Winding detection stand of the present invention comprises: test board bay 1, back up pad 2, fixture rotor 3, motor 4 and air pump 5.Back up pad 2 be subject to air pump 5 drive can oscilaltion be arranged on test board bay 1, motor 4 drives fixture rotor 3 in the interior rotation of stator 6 to be detected, stator 6 to be detected makes to export electromotive force, qualified thereby whether the winding of judging stator interior after detecting by electronic instrument 7 is wound around.
Wherein, test board bay 1 is rectangular frame structure, and motor 4 is vertically arranged in rectangular frame; Test board bay 1 top has rectangular panel 11, these rectangular panel 11 centers offer the through hole passing through for the lower end input rotating shaft of fixture rotor 3, outer four lower stator locating pieces 12, the arcwall face that the interior side-locating face of this lower stator locating piece 12 is and stator to be detected 6 sides adaptations are located of being circumferentially evenly equipped with of through hole; 11 4 jiaos of ，Qie left and right sides, guide pole hole that offer respectively with boss of rectangular panel offer respectively air pump push-rod hole, and air pump 5 is arranged on respectively the left and right sides of rectangular panel 11, and air pump push rod can be stretched out by air pump push-rod hole.
Back up pad 2 is rectangular slab, center offers the opening (stator 6 to be detected can not pass this opening) that the head for fixture rotor 3 passes, outer four upper stator locating pieces 21 and four the stator briquettings 22 of being circumferentially evenly equipped with of opening, these four upper stator locating pieces 21 and four lower stator locating piece 12 intervals arrange, and interior side-locating face is and the adaptive arcwall face of locating in stator to be detected 6 sides; Stator briquetting 22 is Z-shaped, head front end is used for compressing stator to be detected 6 sides, afterbody offers adjusts waist hole, by bolt can before and after adjust be arranged in back up pad 2, four stator briquettings 22 are disposed between stator locating piece 21 and lower stator locating piece 12; Four jiaos of rectangle back up pad 2 are fixed with respectively the guide pole 23 extending vertically downward, and back up pad 2 is when test board bay 1 oscilaltion, and the guide pole hole that guide pole 23 stretches into rectangular panel 11 play the guiding role.Air pump push rod stretches out after the air pump push-rod hole of rectangular panel 11, is installed to the left and right sides of back up pad 2.
As shown in Figure 1, during beginning, the motor 4 detecting on stand is not switched on, and does not work; Air pump 5 is not ventilated, and does not work yet, and back up pad 2 drops in rectangular panel 11.
As shown in Figure 2, while starting to detect, air pump 5 connects pressurized air, air pump push rod protrudes upward back up pad 2 jack-up, and back up pad 2, along guide pole 23 risings, carries on detection stand by stator 6 to be detected afterwards, be placed in back up pad 2, and position by four upper stator locating pieces 21, make stator 6 to be detected coaxial with fixture rotor 3, and adaptation is inserted in; And then by adjustment waist pore structure being fixed in back up pad 2 stator 6 position accurate adjustments to be detected of four stator briquettings 22.
As shown in Figure 3 and Figure 4, now, air pump push rod shrinks and makes back up pad 2 slow decreasings downwards, when declining near rectangular panel 11, by four lower stator locating pieces 12, carry out secondary location again, when guaranteeing that back up pad 2 is fallen in rectangular panel 11, stator 6 to be detected is inserted in fixture rotor 3 adaptations.This detection stand adopts upper and lower stator locating piece and high-precision guide pole to carry out guide-localization, so that stator to be detected 6 adaptations are difficult for occurring catching phenomenon while being inserted in fixture rotor 3, and then impact detects quality.Follow as shown in Figure 5, then three output lines of the stator of stator 6 to be detected are connected on electronic instrument 7.
Now motor 4 energisings drive fixture rotor 3 to rotate, motor 4 adopts constant rotational speed running, therefore fixture rotor 3 also rotates with constant rotational speed, produce constant electromotive force, and then the magnetic field that produces alternation, three phase windings of stator 6 to be detected are cutting magnetic line successively, will induce equal and opposite in direction, differs the AC electromotive force of 120 ° of electrical angles.Now just can observe out the electromotive force that output line sends from electronic instrument 7 undesirable, qualified thereby whether the winding of judging stator interior is wound around.
After judging that whether stator 6 to be detected is qualified, motor 4 power-off, fixture rotor 3 stops operating, air pump push rod upwards extends back up pad 2 jack-up again, back up pad 2, after guide pole 23 risings, is unclamped four stator briquettings 22, and stator 6 to be detected is lifted away to detection stand, air pump push rod shrinks and makes back up pad 2 slow decreasing returns, completes testing process.
This Stator Winding monitor station shelf structure advantages of simple, detection efficiency is high; After motor stator and rotor are fit into electric machine casing, detect again, avoided there is problem because detecting stator winding, and electric machine casing is disassembled and affected efficiency of assembling.
Disclosed is above only several specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
