Description
Technical field
The utility model relates to a kind of fixture, and 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 by the simple frock of the corresponding screw mandrel of common left and right nut screw connection, 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 (paying special attention to is support diameter of stator bore) of stretching motor wound stator by the left and right nut on screw mandrel, reach the object that (axial line of stator and horizontal vertical shape) lifts by crane stator.Owing to being be rotate the motion of main screw mandrel to realize its tensioner (relying on the friction plate on connecting rod and diameter of stator bore to there is certain frictional force) by operator in whole operating process, so, whether the size of the size (frictional force) of its expanding force is said to a certain extent does not have certain safety final conclusion, will easily cause like this occurring there is no certain pretightning force due to the not in place of frictional 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 have employed friction plate, friction plate, after employing a period of time, is easy to wearing and tearing, cause connecting rod and the fastening screw of friction plate outside exposed.As changed not in time, easily by stator inner hole plucking, affecting the quality of fit of stator and support, having 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 cause screw pair heavy wear, replacement cost is larger.So also cause certain economic loss to enterprise and job security is less.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus 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 operator stator press-loading specially and adjustment expanding force time operative employee labour intensity.
According to the technical scheme that the utility model provides, 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 right-handed thread is connected respectively a feed screw nut, each feed screw nut lower end connects 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; Flap seat is connected by alignment pin in the middle part of described main screw mandrel.
Further, feed screw nut connects 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 utility model has the following advantages:
The utility model structure is simple, compact, reasonable, guarantee safety and meet technological operation requirement easily under prerequisite, improve the overall work speed of stator press-loading process, greatly reduce operator stator press-loading specially and adjustment expanding force time operative employee labour intensity; Advantageously in operation, improve stator press-loading quality, provide necessary qualified quality to later process.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
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
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model 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 right-handed thread is connected respectively a feed screw nut 4, each feed screw nut 4 lower end connects a clamp system 8.Rotate main screw mandrel 1 thus drive the feed screw nut 4 on left hand thread and right-handed thread to draw close mutually or disconnected from each other, thus driving clamp system 8 clamp or unclamp motor stator.
Feed screw nut 4 connects dog screw 5, when screwed in place screw 5, feed screw nut 4 is position locking on main screw mandrel 1, can not move left and right; When 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 nut 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 end is connected by screw the clamping plate 11 of circular arc.
Described clamping plate 11 front end is provided with the wearing layer 10 of circular arc, and wearing layer 10 adopts soft rubber material to make.
Described clamping bar 9 lower end connects locking nut 15, is locked by rotary sleeve 12 by locking nut 15.
Described main screw mandrel 1 two ends connect handwheel 7 by flat key 6, rotate main screw mandrel 1 by handwheel is convenient.
Connect flap seat 2 by alignment pin 3 in the middle part of described main screw mandrel 1, flap seat 2 conveniently carries out handling.
Operation principle of the present utility model is: during 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 to be sling motor stator by flap seat.Because axis stator is horizontal, while lifting after clamping it, 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 the wearing layer of soft rubber material making is set in clamping plate front end, its frictional force is increased greatly, not easily makes 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, make clamping bar clamp or unclamp motor stator.Without the need to using too much instrument, (when motor stator specification is larger, two operative employees can be had to operate rotate rotate the handwheel at main screw mandrel two ends, to guarantee enough clamping forces) simultaneously so, operation is also very simple, and time shorten, improves productivity ratio.
The utility model structure is simple, compact, reasonable, guarantee safety and meet technological operation requirement easily under prerequisite, improve the overall work speed of stator press-loading process, greatly reduce operator stator press-loading specially and adjustment expanding force time operative employee labour intensity; Advantageously in operation, improve stator press-loading quality, provide necessary qualified quality to later process.
