The specific embodiment
In order further to understand this many kinds of New-energy electric vehicle motor, on assembly line, carry out the clamping device of mechanical overturn, below in conjunction with accompanying drawing, technical scheme of the present invention is elaborated.
In this case, the basic assembly technology of motor is that motor rotor part is assembled together together with back end cover for motor, then jointly packs the downward stator component of front end into; And stator component front end has adopted technique drive end bearing bracket, be assembled together and accept again rotor part with stator component.After above-mentioned assembling content completes, motor is carried out to 180 degree upsets, allow motor front end upwards.Next dismantle processes drive end bearing bracket, mounted motor drive end bearing bracket, is mounted to motor assembly to this motor.Motor assembly is turned over and turn 90 degrees into horizontal putting, carry out before motor assembly dispatches from the factory testing.
Above-mentioned technique is also the motor general assemble technique that comprises common electric machine.In assembling process, motor need to carry out twice upset: one, the motor with technique drive end bearing bracket is carried out to 180 degree upsets; Two, motor assembly is carried out to 90 degree upsets.In this case, need the motor of clamping to be divided into motor with air cooling and water cooled machine, motor with air cooling has A model and Type B number, and water cooled machine has C model and D model.Motor model is from A to D, and power increases successively, and size also increases successively.A model motor is about 6 kilowatts, and D model motor is about 30 kilowatts.
A model motor with air cooling 180 degree turning and clamping devices comprise: fastening positioning sleeve 1, finger plate 2, clamp positioning sleeve 3, fastening bolt 4, upper fixture block 5, plate washer 6, lower fixture block 7; Described upper fixture block is the upper fixture block of the first structure, and lower fixture block is the lower fixture block of the first structure, and described finger plate structure is the finger plate of the first structure, and clamping device is identical with left-half by right half part, and two parts are added together as a set of.Often having put two the first structure finger plates, is rectangle, on finger plate the porose vertical center line of pressing finger plate symmetrical, the horizontal central line of also pressing finger plate is symmetrical up and down.In the geometric center of plate, there is a datum hole, for matching with tipper gyroaxis.Around datum hole, there are eight uniform soket head cap screw holes, for the gyroaxis with flange disc on finger plate and tipper is fixed together with soket head cap screw, when gyroaxis rotates, drive finger plate to rotate.On every finger plate, be provided with Kong1a, hole 1b until 4bBa Ge hole, Kong4a, hole.Zhe Bage hole has respectively coordinate position accurately, and aperture is identical.Cong Kong1aDao hole 4b, porose vertical center line and the horizontal center line symmetry of pressing of institute, the centre-to-centre spacing in each horizontal line Shang Liang hole is identical.Kong1a, Kong2a, Kong3a, hole 4a equates and equals Kong1b, Kong2b, Kong3b, hole 4b to the distance of vertical center line to the distance of vertical center line.The endoporus of fastening positioning sleeve and coaxial for locating Wai garden, internal thread hole and endoporus are coaxial, and endoporus is datum hole, and eight datum holes of 1a to 4b on the outer garden diameter of fastening positioning sleeve and finger plate are interference fit each other.Eight adapter sleeves 1 are pressed into hole 1a, 1b, 3a, 3b from the back side of finger plate respectively.The endoporus of clamp positioning sleeve is coaxial with the clamp positioning sleeve external diameter for feeling relieved, and internal diameter is datum hole, and the locating hole on external diameter and upper fixture block and the locating hole on lower fixture block are interference fit.Four clamp positioning sleeves 3 are pressed into respectively the locating hole on fixture block 5.Four clamp positioning sleeves 3 are pressed into respectively the locating hole on lower fixture block 7.Upper fixture block 5 is two, and basic configuration is " L " shape, and in order to clamp back end cover for motor, because back end cover for motor is circular, upper fixture block 5 is made " V " shape with motor contact site.The bottom surface of upper fixture block 5 contacts with the first structure finger plate 2, is processed with two datum holes on the bottom surface of upper fixture block 5, and pitch of holes equals the spacing between the 1b of Kong1aHe hole.On every, on fixture block 5, be pressed into after two clamp positioning sleeves 3, with two fastening bolts 4, through the clamp positioning sleeve 3 of upper fixture block 5, be fastened on fastening positioning sleeve 1.Because the endoporus of garden outside the location of fastening bolt 4 and clamp positioning sleeve 3 and fastening positioning sleeve 1 coordinates, be reference axis and coordinate with datum hole, when therefore upper fixture block 5 is assembled together with finger plate 2, can on finger plate 2, accurately locate, after the each dismounting of upper fixture block 5, reinstall and can keep original installation site and installation accuracy.Can realize fast assembling-disassembling, meet quick change requirement.Locating hole phase on fastening positioning sleeve 1 and finger plate 2 is interference fit each other, and when fastening bolt 4 is tightened on fastening positioning sleeve 1, fastening positioning sleeve 1 can not rotate loosening, and fastening bolt 4 can fully be tightened.Lower fixture block 7 is two, and basic structure is identical with upper fixture block 5, and difference is the shape of retaining part, due to clamp to as if technique drive end bearing bracket, be square, band groove, lower fixture block 7 is made orthoscopic convex shape with technique drive end bearing bracket contact site.
