Description

The motor disassembling jig

Technical field

The utility model relates to the motor disassembling jig, and particularly a kind of axle center of can removing is not at the motor disassembling jig of the motor of center.

Background technology

Motor is an instrument commonly used in the factory, often is used to drive other machine run.And in real work, motor will be fixed usually, and the rotation of motor self is passed to other machine.As shown in Figure 1, it is a kind of motor schematic diagram on the existing factory streamline.The integral body of this motor 103 is enclosed within on the fixed axis 105, and the steel plate 107 of four angles of motor 103 by the centre is fixed on the pedestal 109, and motor 103 just can not rock like this.During work, motor 103 runnings drive fixed axis 105 rotations, and fixed axis 105 rotations drive chain and rotate, thus the rotation of guide roller, and so streamline has just formed.

But after the increase and machine long-time running along with service life, motor can occur that some are unusual sometimes, and is not smooth etc. as leakage of oil, different sound, operation, thereby influenced the operation of equipment integral.So need in the case of necessary motor to be dismantled and cleaned replacing, and for some integrated mills, under the motor quantity situation how, the instrument of dismounting motor is necessary.

The instrument of dismounting motor commonly used is to draw horse in the factory now, as shown in Figure 2, it is existing a kind of Three-claw pull-horse, when the utilization Three-claw pull-horse is dismantled motor, fasten the motor edge with three jaws 203 that draw horse, withstand fixed axis with its driving screw 205 by the axle center of motor then, rotation driving screw 205, and the little progress by driving screw 205, three jaws are slowly extracted motor from fixed axis.

But the axle center of motor is not necessarily to be in the center on its surface, and the angle between three jaws of Three-claw pull-horse is 120 degree, and its perspective plane is an equilateral triangle, and its driving screw is to be in the center of drawing horse.And Three-claw pull-horse not just, two most pawls, four paws etc. draw the driving screw of horse also all to be in the center of drawing horse.Therefore, if the axle center of motor is not under the situation of center, after driving screw inserts motor, the position of its jaw with regard to bad fixing, even if fixed, draws the driving screw of horse will be askew to fall at the edge of motor, its function can't normally be put to good use, and motor also can't be extracted naturally.

The utility model content

The purpose of this utility model provides a kind of motor disassembling jig, existingly draws horse can't extract the axle center not in the problem of the motor of center to solve.

The utility model proposes a kind of motor disassembling jig, in order to motor is removed from base, this motor bottom is connected with steel plate, be provided with around it in order to being fixed at least two fixing holes on the base, the motor disassembling jig comprises fixed mechanism, in order to motor and fixed mechanism are locked at least two bolts, driving screw and the driving screw rotating mechanism on the steel plate.Fixed mechanism is provided with in order to the screwed hole that runs through driving screw and in order at least two through holes of through bolt, and the position of screwed hole is corresponding with the shaft core position of motor, and the position of through hole is corresponding with the position of fixing hole.

According to the described motor disassembling jig of the utility model preferred embodiment, its driving screw rotating mechanism is a spanner.

According to the described motor disassembling jig of the utility model preferred embodiment, the position corresponding to four angles of motor on its fixed mechanism is provided with four through holes.

With respect to prior art, the utility model has the advantages that: the utility model can be not only laborsaving but also dismantle following axle center apace not at the motor of center, improved the efficient of changing unusual motor in the factory, also guaranteed the production efficiency of factory.

Embodiment

Below in conjunction with accompanying drawing, specify the utility model.

Motor disassembling jig of the present utility model is in order to remove motor from base, see also Fig. 3, it is a kind of motor disassembling jig schematic diagram of the utility model embodiment, and it comprises fixed mechanism 301, two bolts 303, driving screw 305 and driving screw rotating mechanisms 307.Wherein, four angles of fixed mechanism 301 are provided with four through holes 309, and the centre is provided with screwed hole 311.Two bolts 303 run through two through holes 309 at diagonal angle.Driving screw 305 screws in the screwed hole 311.Rotary screw 307 is arranged on the driving screw 305.

See also Fig. 4, the schematic diagram when it is motor disassembling jig of the present utility model dismounting motor.When motor need be dismantled, bolt 303 penetrated through hole 309 on the fixed mechanism 301 after, run through fixing hole and steel plate 107 on the motor 103 again, and fixed mechanism 301, motor 103 and steel plate 107 locked.Then driving screw 305 is screwed in the screwed hole 311 on the fixed mechanisms 301, and withstand the fixed axis that motor 103 is overlapped.Then utilize rotary screw 307 rotation driving screws 305, the screw thread of fixed mechanism 301 on driving screw 305 outwards moved, and it is outwards mobile with steel plate 107 to drive motor 103, because driving screw 305 withstands fixed axis, thereby the rotation driving screw 305 fixed axis is separated gradually with motor 103, thereby motor 103 is extracted from base 109.

In actual applications, the shape of fixed mechanism 301 can cooperate motor setting, and when being circular as motor, fixed mechanism 301 also can be circle, and when motor was square, fixed mechanism 301 also can be for square.And through hole 309 also can be adjusted according to actual needs with the position of bolt 303.As shown in Figure 5, it is a kind of fixed mechanism schematic diagram of the utility model embodiment.This fixed mechanism 301 is provided with four through holes 309, and equally according to actual needs, through hole 309 also can be six or eight.And being shaft core positions according to motor, the position of the screwed hole 311 on the fixed mechanism 301 is provided with, the screwed hole 311 of Fig. 5 is in the position of fixed mechanism 301 centers under taking back, so this fixed mechanism 301 can be used to dismantle the take back motor of upper/lower positions of axle center.

The shape of driving screw 305 can be provided with according to screwed hole 311 and fixed axis that motor overlapped, as shown in Figure 6, the bottom of this driving screw 305 is divided into the part that screws in fixed mechanism 301, and because of need withstanding fixed axis in its lower end, thereby its lower end can be arranged to and the corresponding shape of fixed axis.The mid portion of driving screw 305 is provided with screw thread, and the screw thread on the screwed hole 311 of this screw thread and fixed mechanism 301 is corresponding.The upper end of driving screw 305 is used for contacting with rotary screw 307, and in actual applications, rotary screw 307 can be a spanner.

More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection range of the present utility model.
