Abstract
The utility model discloses a kind of push-and-pull jockey pulley nylon pin extractor, comprise U-shaped seat, screw rod, it is characterized in that: on two sidewalls of described U-shaped seat, be respectively equipped with through hole, the hole that through hole one is 30mm for diameter, the screwed hole that through hole two is M12, and through hole one and through hole Er center are on the same line, nylon pin is through through hole one, and screw rod is through through hole two, and screw rod is M12 screw rod.This apparatus structure is simple, profile is little, safe and reliable, applicable to the elastic dowel pin shaft coupling nylon pin dismounting that operating space is little, uses.After the utility model is implemented, without dismantling motor, efficiency obviously improves again, and labour intensity reduces.
Description
Technical field
The utility model relates to a kind of push-and-pull jockey pulley nylon pin extractor, belongs to mechanical field.
Background technology
Push-and-pull jockey pulley catcher is elastic dowel pin shaft coupling, and it is mainly with the nylon pin of ￠ 20*60, two half a couplers to be linked up.
Although monthly check and change nylon pin during equipment regular inspection, because it starts frequently aborning.Always have disconnected pin phenomenon, very difficult while changing nylon pin, during operation, because operating space is little, with hand hammer and the punching pin write off period of the day from 11 p.m. to 1 a.m, more than hand hammer and punching pin angle reach 30 degree, substantially do not use strength, so replacing all needs after the dismounting of motor foundation bolt at every turn, and by after its displacement 100mm-300mm, re-use hand hammer and punching pin write off, during recovery, readjust shaft coupling and motor.And the time of adjusting each time shaft coupling and motor is 2 hours.
Summary of the invention
The utility model provides a kind of simple in structure, yielding, not time saving and energy saving push-and-pull jockey pulley nylon pin extractor.
The technical solution adopted in the utility model is: a kind of push-and-pull jockey pulley nylon pin extractor, comprise U-shaped seat, screw rod, it is characterized in that: on two sidewalls of described U-shaped seat, be respectively equipped with through hole, the hole that through hole one is 30mm for diameter, the screwed hole that through hole two is M12, and through hole one and through hole Er center are on the same line, nylon pin is through through hole one, and screw rod is through through hole two, and screw rod is M12 screw rod.
The width of described U-shaped seat is 105mm, is highly 70mm.
The utility model push-and-pull jockey pulley nylon pin extractor device, there is the concentric through hole of ￠ 30 and M12 its U-shaped seat both sides.While using this device, first Building U is stuck on shaft coupling, hole center-aligned, and U-shaped seat both sides ￠ 30 YuM12Kong centers with coupler hole center in 0.05mm tolerance, the hole that the screw by rotating band cross bar M12 is 30mm by the nylon pin that breaks from Building U one side diameter, take out.
The push-and-pull jockey pulley nylon pin extractor that the utility model provides, simple in structure, profile is little, safe and reliable, applicable to the elastic dowel pin shaft coupling nylon pin dismounting that operating space is little, use.After the utility model is implemented, without dismantling motor, efficiency obviously improves again, and labour intensity reduces.
Below in conjunction with drawings and Examples, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state diagram of the present utility model.
In figure, 1 is U-shaped seat, and 2 is that through hole one, 3 is that through hole two, 4 is screw rod, and 5 is nylon pin, and 6 is shaft coupling, and 7 is motor, and 8 is reductor.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of push-and-pull jockey pulley nylon pin extractor, comprise U-shaped seat 1, screw rod 4, is respectively equipped with through hole on two sidewalls of described U-shaped seat 1, the hole that through hole 1 is 30mm for diameter, the screwed hole that through hole 23 is M12, and the center of through hole 1 and through hole 23 is on the same line, and nylon pin is through through hole 1, screw rod 4 is through through hole 23, and screw rod 4 is M12 screw rod.
The width of described U-shaped seat is 105mm, is highly 70mm.
First this device arranges U-shaped seat, then in U-shaped seat both sides, ￠ 30 and M12 through hole is set, and M12*75 screw rod is just joined with nylon pin through M12 through hole, the hole that the screw rod by rotating band cross bar M12 is 30mm by disconnected nylon pin from Building U one side diameter, takes out.
Fig. 2 is use state diagram of the present utility model.Push-and-pull jockey pulley catcher is elastic dowel pin shaft coupling, two half a couplers 6 connect by nylon pin 5, nylon pin 5 is through through hole 1, screw rod 4 is through through hole 23, nylon pin 5 joins with screw rod 4 ends, when nylon pin breaks, by the screw rod to U-shaped seat 1 interior sideway swivel M12, nylon pin 5 is taken out from through hole 1.
