Abstract
A hydraulic self-clamping pulling machine for disassembling a belt pulley. The machine body is provided with three movable claws which are uniformly distributed, the movable claws are arranged on the machine body through pin shafts, and the movable claws are always in an inward inclined state under the action of a tension spring connected with the lower end of the movable claws. The middle part of the machine body is fixed with an oil hydraulic cylinder and a top rod of a cock in the cavity of the oil hydraulic cylinder, and the cavity of the oil hydraulic cylinder is communicated with a manual hydraulic pump through a leather hose. The utility model has the characteristics of adopt hydraulic drive, realize automatic dress card, labour saving and time saving alleviates intensity of labour, improves work efficiency. The belt pulley has the advantages of simple structure, lightness, flexibility, convenient operation and capability of disassembling belt pulleys with various specifications.
Description
A kind ofly dismantle the special-purpose machinery that belt pulley is used.
Owing to adopt interference fit between belt pulley and the Pulley shaft, therefore belt pulley being pulled down from axle is a harder job.With the original method that hammer strikes, crowbar is prized, be difficult to prove effective on the one hand, damage belt pulley and other parts on the other hand easily.At present, generally adopt the method for drawing, promptly at first hook around the belt pulley, tie up to rope on the drag hook with the mode hard draw of ceeling car then, belt pulley is pulled out from axle with drag hook with drag hook.This method wastes time and energy, and does not also reach the dismounting purpose sometimes.
The purpose of this utility model provides a kind of hydraulic pressure from the OK a karaoke club machine, accomplishes to dismantle belt pulley easily, alleviates labor strength.
The purpose of this utility model is achieved in that three equally distributed movable claws on body, movable claw is installed on the body by bearing pin, with tension spring effect that its lower end links to each other under, movable claw is in intilted situation all the time; The body middle part is fixed with oil hydraulic cylinder and the push rod of cock in the oil hydraulic cylinder cavity; The cavity of oil hydraulic cylinder is connected with hydraulic hand-pump by leather hose.
Using method is as follows: at first live body with hand rest, make movable claw aim at belt pulley, firmly one push away.At this moment movable claw will outwards open, and belt pulley enters in the movable claw, and movable claw automatically resets under the effect of tension spring immediately, also hook belt pulley tightly toward interior gathering.Meanwhile, push rod and Pulley shaft are close to.Push hand oil pump then, oil enters in the cavity of oil hydraulic cylinder by leather hose, promotes the push rod in the oil hydraulic cylinder, thereby belt pulley is pulled out from axle.
In order to make the utility model can dismantle the belt pulley of plurality of specifications, the pin-and-hole of using for the installation movable claw on the body has more than 2 groups.Movable claw inserts not on the same group the pin-and-hole by bearing pin, can dismantle the belt pulley of different size.
Compared with the prior art, characteristics of the present utility model are to adopt hydraulic drive, realize automatic card-loading, and are time saving and energy saving, reduce labor intensity, and increase work efficiency.It is simple in structure, light and handy flexibly, the belt pulley of easy to operate, detachable various different sizes.
Fig. 1 is that hydraulic pressure is from OK a karaoke club machine structural representation.
Describe concrete structure of the present utility model in detail below in conjunction with Fig. 1 and embodiment.
Three movable claws 1 are installed on the body 9 evenly distributedly by bearing pin 3 respectively, the pin-and-hole 6 that supply and marketing axle 3 inserts on the body 9 has three groups, tension spring 7 one ends are enclosed within on the reference column 5 by pulling-on piece 4, the other end is connected on the outside, movable claw 1 lower end, body 9 middle parts are fixed with oil hydraulic cylinder 10 and the push rod 2 of cock in oil hydraulic cylinder 10 cavitys, and the cavity of oil hydraulic cylinder 10 is connected with hydraulic hand-pump 12 by leather hose 11.
Claims (2)
1, a kind ofly dismantles hydraulic pressure that belt pulley uses from the OK a karaoke club machine, it is characterized in that three movable claws (1) are installed on the body (9) evenly distributedly by bearing pin (3) respectively, tension spring (7) one ends are enclosed within on the reference column (5) by pulling-on piece (4), the other end is connected on the outside, movable claw (1) lower end, body (9) middle part is fixed with oil hydraulic cylinder (10) and the push rod (2) of cock in oil hydraulic cylinder (10) cavity, and the cavity of oil hydraulic cylinder (10) is connected with hydraulic hand-pump (12) by leather hose (11).
2, hydraulic pressure according to claim 1 is characterized in that the pin-and-hole (6) that has two groups of above supply and marketing axles (3) to insert on the body (9) from the OK a karaoke club machine.
