Abstract
The utility model discloses a manufacturing device of a high precision hollow-cup electric machine rotor, characterized in that: the manufacturing device comprises a material chamber (1), a pressure plate (2) in the material chamber and a gating plate (3), wherein the material chamber (1) is in fit connection with a middle ring (5) and the middle ring (5) is in fit connection with a positioning sleeve (6), mold cores (4) penetrate through the positioning sleeve and the middle ring and a fixation plate (7) is set at the lower part of the mold cores and a lower plate is set below the fixation plate and a knockout-pin plate (9) is set below the lower plate and a knockout-pin (10) is set above the knockout-pin plate (9). The hollow-cup electric machine rotor is processed and arranged, the middle ring in the device is used as the reference of the process and arrangement, thus the axiality requirement of the finished products of the electric machine rotor is finely ensured and the rotor radial run-out tolerance is controlled in 0.10mm. After the electric machine is assembled, the dynamic balance is good and the operation of the electric machine is stable and the shock of the electric machine is controlled.
Description
Technical field
The utility model relates to a kind of manufacturing frock hermetically-sealed construction of rotor, particularly a kind of manufacturing frock of high accuracy drag cup rotor.
Background technology
In the manufacturing process of drag cup rotor, the circular runout of rotor is an important indicator that influences motor performance.Present manufacturing frock circular runout is in 0.18～0.25 scope.Because circular runout is bigger, the dynamic balancing of rotor is bad, vibrates during the motor operation.
The principal element that present manufacturing frock influences circular runout has following reason: the one, and the location of rotor in moulds of industrial equipment is to realize by the location hole of armature spindle in the core rod of encapsulating mould, under the condition of high temperature, the wearing and tearing of location hole are very fast.The 2nd, because the diameter of armature spindle is generally in the scope of 3～6mm, and armature spindle length is 8～9 times of diameter, belongs to the processing of overlength aperture, and machining accuracy is difficult to guarantee.The 3rd, axle is difficult to grasp with the reasonable supporting clearance in hole, and the location can not guarantee when the gap was big; The gap is too little, and axle is transferred to from rotor easily during depanning.
The utility model content
The purpose of this utility model is, a kind of manufacturing frock of high accuracy drag cup rotor is provided, and can guarantee the axiality requirement of rotor, the good dynamic balance of rotor, and it is little during the motor operation vibration to take place.
The technical solution of the utility model: a kind of manufacturing frock of high accuracy drag cup rotor, it is characterized in that: comprise the material chamber, expect indoor pressing plate and the gate plate of being provided with, material chamber and centre circle are connected, and centre circle and positioning sleeve are connected, and are installed with core rod in positioning sleeve and the centre circle, the bottom of core rod is provided with fixed head, the fixed head below is provided with lower plate, and the below of lower plate is provided with the push rod plate, and the push rod plate is provided with push rod.
In the manufacturing frock of aforesaid high accuracy drag cup rotor, the axiality of described centre circle and positioning sleeve is not more than 0.02mm.
In the manufacturing frock of aforesaid high accuracy drag cup rotor, described core rod external diameter is less than rotor lining axis hole final size 0.4～0.8mm.
In the manufacturing frock of aforesaid high accuracy drag cup rotor, described core rod external diameter is less than rotor lining axis hole final size 0.6mm.
Compared with prior art, the utility model with the benchmark of the centre circle in the frock as processing and assembling, therefore can well guarantee the axiality requirement of rotor finished product axle and cup all the time when processing and device drag cup rotor.Drag cup rotor runout tolerance of the present utility model can be controlled in the 0.10mm.Motor assembling back good dynamic balance, motor operates steadily, and the vibrations of motor are controlled.
Description of drawings
Fig. 1 is a knot schematic diagram of the present utility model.
Being labeled as in the accompanying drawing: 1-expects the chamber, 2-pressing plate, 3-gate plate, 4-core rod, 5-centre circle, 6-positioning sleeve, 7-fixed head, 8-lower plate, 9-push rod plate, 10-push rod, 11-rotor.
Embodiment
Below in conjunction with drawings and Examples the worker of a kind of high accuracy drag cup rotor of the present utility model is pretended further detailed description, but not as the foundation of the utility model being done any restriction.
Embodiment: the structured flowchart of the manufacturing frock of high accuracy drag cup rotor of the present utility model as shown in Figure 1.Comprise material chamber 1, material is provided with pressing plate 2 and gate plate 3 in the chamber 1, material chamber 1 is connected with centre circle 5, centre circle 5 is connected with positioning sleeve 6, be installed with core rod 4 in positioning sleeve 6 and the centre circle 5, the bottom of core rod 4 is provided with fixed head 7, and fixed head 7 belows are provided with lower plate 8, the below of lower plate 8 is provided with push rod plate 9, and push rod plate 9 is provided with push rod 10.Centre circle 5 is not more than 0.02mm with the axiality of positioning sleeve 6.The external diameter of described core rod 4 is less than rotor lining axis hole final size 0.6mm, and the promptly monolateral surplus that leaves 0.3mm is so that carry out right boring processing.
Operation principle of the present utility model
The utility model is the moulds of industrial equipment that carry out the injection moulding encapsulation on common plastic compression machine, is suitable for the production of be pilot.Centre circle 5 in the mould is the benchmark in processing and when assembling, adds man-hour in that drag cup rotor 11 is carried out right boring, and drag cup rotor 11 will be that benchmark carries out the axiality adjustment with centre circle 5.When guide-localization, be benchmark also with centre circle 5, also be to be benchmark when pressing 11 of drag cup rotors with centre circle 5, because in the processing of drag cup rotor 11 and assembling overall process all is to be benchmark with centre circle 5, so fully guaranteed the axiality of axle to drag cup rotor 11 cups.
