Description
Technical field
The present invention relates to a kind of fixture, a kind of motor stator press-fits special alignment jig specifically, belongs to motor production equipment technical field.
Background technology
At present, general motor stator press-fits, normally coordinate the simple frock of corresponding screw mandrel with common left and right nut, first stretch into stator inner hole (axial line of stator becomes horizontal and is lying on workbench), rotate its screw mandrel, drive corresponding connecting rod to carry out the internal diameter (pay special attention to is support diameter of stator bore) of stretching motor wound stator by the left and right nut on screw mandrel, the object that reaches (axial line of stator and horizontal vertical shape) and lift by crane stator.Because in whole operating process being is to rotate main screw mandrel to move to realize by its tensioner (relying on friction plate and diameter of stator bore on connecting rod to have certain frictional force) by operator, so, whether the size of the size (frictional force) of its expanding force is said does not to a certain extent have certain safety final conclusion, will easily cause like this occurring because frictional force not in place do not have certain pretightning force, and appear at coming off of workpiece stator and tension tool in whole lifting process, cause safe mass accident.In addition, again owing to having adopted friction plate, friction plate used after a period of time, was easy to wearing and tearing, caused the screw of connecting rod and the fastening use of friction plate outside exposed.As changed not in time, easily by stator inner hole plucking, affect the quality of fit of stator and support, have a strong impact on the overall assembly quality of motor.Moreover, because left and right screw mandrel rotary moveable is frequent, as easy as rolling off a logly causing screw pair heavy wear, replacement cost is larger.So also to enterprise cause certain economic loss and job security less.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of motor stator to press-fit special alignment jig, guarantee safety and meet technological operation requirement easily under prerequisite, improve the overall work speed of stator press-loading process, greatly reduce the labour intensity of operator stator press-loading operative employee specially and while adjusting expanding force.
According to technical scheme provided by the invention, motor stator press-fits special alignment jig and comprises main screw mandrel, it is characterized in that: main screw mandrel is provided with left hand thread and the right-handed thread of symmetrical distribution, the left hand thread of main screw mandrel with on right-handed thread, be connected respectively a feed screw nut, each feed screw nut lower end connect a clamp system; Described clamp system comprises clamping bar, clamping bar upper end connection wire rod nut, and lower end connects rotary sleeve, and rotary sleeve connects bracket by the stop screw of both sides, and bracket front end is connected by screw the clamping plate of circular arc; Described main screw mandrel middle part connects flap seat by alignment pin.
Further, the upper connection of feed screw nut dog screw.
Further, clamping plate front end is provided with the wearing layer of circular arc, and wearing layer adopts soft rubber material to make.
Further, clamping bar lower end connects locking nut.
Further, main screw mandrel two ends connect handwheel by flat key.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, rationally, guarantee safety and meet technological operation requirement easily under prerequisite, improve the overall work speed of stator press-loading process, greatly reduce the labour intensity of operator stator press-loading operative employee specially and while adjusting expanding force; More be conducive to operation, improve stator press-loading quality, provide necessary qualified quality to later process.

Fig. 2 is clamp system structural representation.
The main screw mandrel of description of reference numerals: 1-, 2-flap seat, 3-alignment pin, 4-feed screw nut, 5-dog screw, 6-flat key, 7-handwheel, 8-clamp system, 9-clamping bar, 10-wearing layer, 11-clamping plate, 12-rotary sleeve, 13-stop screw, 14-bracket, 15-locking nut.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises main screw mandrel 1, main screw mandrel 1 is provided with left hand thread and the right-handed thread of symmetrical distribution, the left hand thread of main screw mandrel 1 with on right-handed thread, be connected respectively a feed screw nut 4, each feed screw nut 4 lower ends connect a clamp system 8.Drive feed screw nut 4 on left hand thread and right-handed thread to draw close mutually or disconnected from each other thereby rotate main screw mandrel 1, thereby drive clamp system 8 to clamp or unclamp motor stator.
On feed screw nut 4, connect dog screw 5, in the time of screwed in place screw 5, feed screw nut 4 is position locking on main screw mandrel 1, can not move left and right; In the time unclamping dog screw 5, feed screw nut 4 can move freely on main screw mandrel 1.
Described clamp system 8 comprises clamping bar 9, clamping bar 9 upper end connection wire rod nuts 4, and lower end connects rotary sleeve 12, and rotary sleeve 12 connects bracket 14 by the stop screw 13 of both sides, and bracket 14 front ends are connected by screw the clamping plate 11 of circular arc.
Described clamping plate 11 front ends are provided with the wearing layer 10 of circular arc, and wearing layer 10 adopts soft rubber material to make.
Described clamping bar 9 lower ends connect locking nut 15, by locking nut 15, rotary sleeve 12 are locked.
Described main screw mandrel 1 two ends connect handwheel 7 by flat key 6, are facilitated and are rotated main screw mandrel 1 by handwheel.
Described main screw mandrel 1 middle part connects flap seat 2 by alignment pin 3, and flap seat 2 conveniently carries out handling.
Operation principle of the present invention is: when work, rotates main screw mandrel both sides handwheel, drives clamp system to adjust spacing by the feed screw nut on main screw mandrel, thus clamping motor stator.Then by the flap seat motor stator of slinging.Because axis stator is horizontal, when lifting after it is clamped, due to rotary sleeve and bracket assembly connection, the middle stop screw that adopts can carry out radial rotating.Owing to adopting the clamping plate of circular arc, and at clamping plate front end, the wearing layer that soft rubber material is made is set, its frictional force is increased greatly, be difficult for making motor stator landing easily from clamp system.
Owing to unloading in the middle of process in whole installation, only need rotate rotation hand wheel with hand, clamping bar is clamped or unclamp motor stator.Without using too much instrument, (in the time that motor stator specification is larger, can have two operative employees to operate the handwheel that rotates rotation main screw mandrel two ends, to guarantee enough clamping forces) simultaneously so, operate also very simply, time shorten, has improved productivity ratio.
The present invention is simple in structure, compact, rationally, guarantee safety and meet technological operation requirement easily under prerequisite, improve the overall work speed of stator press-loading process, greatly reduce the labour intensity of operator stator press-loading operative employee specially and while adjusting expanding force; More be conducive to operation, improve stator press-loading quality, provide necessary qualified quality to later process.
