Description
Technical field
The utility model relates to special tool for examination and repair technical field, particularly one dismounting electric motor fan draw bench special.
Background technology
Electric motor fan is the thermal component of motor, can have a strong impact on the normal operation of motor, sometimes even also can cause burn-down of electric motor after damage, and therefore the normal operation of maintenance to motor of daily electric motor fan is particularly important.In prior art, fan is disassembled employing from motor shaft and first the set screw on rotating shaft afterbody fan blade or pin is backed out, then beat in fan blade surrounding with hammer.The method, the take-down time is long, inefficiency, and hammer can cause damage to fan blade and bearing, and bearing position gap hour is difficult to operation.
Therefore, develop one and do not limit by place, be applicable to any maintenance place, use flexibly, lightweight, volume is little, service kit easy to carry, be special tool for examination and repair industry in the urgent need to.
Utility model content
Long for solving the above-mentioned dismounting electric motor fan time, inefficiency, hammer can cause damage to fan blade and bearing, and bearing position gap hour is difficult to the problems such as operation, and the utility model adopts following technical scheme:
The utility model provides a kind of dismounting electric motor fan draw bench special, the pulling claw comprising supporting seat, be provided with externally threaded screw mandrel and be arranged in parallel with described screw mandrel, it is characterized in that: in the middle part of described supporting seat, be provided with the screwed hole installing screw mandrel, two ends are provided with baffle plate, described screwed hole coordinates with screw mandrel, described supporting seat is provided with the groove perpendicular to described screw mandrel; Described pulling claw is along described concave slot sports.
Preferably, described supporting seat, screwed hole, baffle plate are integrated casting and form.
Preferably, the other end of described screw mandrel is provided with nut, and described screw mandrel and described nut are integrated casting and form.
Preferably, the other end of described screw mandrel is provided with nut, and described screw mandrel and described nut are integrated casting and form.
Preferably, the external screw thread of described screw mandrel is trapezoidal thread.
Preferably, described pulling claw is provided with two.
Advantage of the present utility model and beneficial effect are: provide a kind of dismounting electric motor fan draw bench special, do not limit by place, be practically applicable to any maintenance place, use flexibly, lightweight, volume is little, service kit easy to carry.
Accompanying drawing explanation
Fig. 1 is the front view of the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the top view of the structural representation of a kind of embodiment of the utility model.
In figure, 1 is supporting seat, and 2 is screw mandrel, and 3 is nut, and 4 is screwed hole, and 5 is baffle plate, and 6 is pulling claw, and 7 is groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described further.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
The technical scheme that the utility model is specifically implemented is:
As shown in Figure 1 and Figure 2, the utility model provides a kind of dismounting electric motor fan draw bench special, the pulling claw (6) comprising supporting seat (1), be provided with externally threaded screw mandrel (2) and be arranged in parallel with screw mandrel, supporting seat (1) middle part is provided with the screwed hole (4) installing screw mandrel, two ends are provided with baffle plate (5), screwed hole (4) coordinates with screw mandrel (2), supporting seat (1) is provided with the groove (7) perpendicular to screw mandrel (2), two pulling claws (6) can along groove (7) freely-movable, to adapt to concrete operations bearing clearance.
In the present embodiment, supporting seat (1), screwed hole (4), baffle plate (5) are integrated casting and form, and screw mandrel (2) and nut (3) are integrated casting and form, and intensity is large, and not easy fracture is easily shaping, and then use casting best.
In the present embodiment, the external screw thread of screw mandrel (2) adopts trapezoidal thread, and intensity is high, and centering is good, and gap is adjustable.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
