Abstract
The utility model discloses the structure of pin for convenience detach on a kind of coupling, coupling is circumferentially evenly equipped with one group of conical bore, each conical bore coordinates with the conical surface in the middle part of pin, coupling between adjacent two conical bores has a tapped hole, and these tapped holes are uniform along the circumference of coupling; The end face of the little head end of pin and the bulb end in contact of ejector pin, and the blind hole drive fit on the roundlet shell of column of ejector pin and pressing plate; The both sides of pressing plate have a screw via hole, and after two attachment screws are each passed through the screw via hole on pressing plate, the tapped hole corresponding with on coupling is connected.The utility model moves to make pressing plate by tightening two attachment screws together with ejector pin, thus the conical surface in the middle part of pin and the conical bore on coupling are disengaged, thus pin of can dismantling quickly and easily, but this structure needs to tighten two attachment screws and just to dismantle pin, operation or some inconvenience, adopt when being therefore specially adapted to narrow space.
Description
Technical field
The utility model belongs to gas compressor transmission of power field, particularly relates to the structure of pin for convenience detach on a kind of coupling.
Background technique
At present, gas compressor is generally connected with the output shaft of motor by flywheel, coupling, to accept the power of motor.Meanwhile, coupling is connected with flywheel by the pin of taper, and is set with elastic washer at the stub end of pin, and the tapered portion in the middle part of pin coordinates with the cone shape hole on coupling, and the little head end of pin is connected with locking nut.
When elastic washer changed by needs, just need pin of first dismantling, and pin and coupling are coordinated by conical surface, this conical surface coordinates with self-locking performance, and the side of coupling is the end cap of motor, this spatial position is not easy to again use the instruments such as hammer to beat the little head end of pin, so just can not facilitate, be pulled down by pin effortlessly, is badly in need of solving above-mentioned technical barrier for this reason.
Model utility content
Technical problem to be solved in the utility model is the structure providing pin for convenience detach on a kind of coupling, for pin of dismantling conveniently, effortlessly.
The technical solution of the utility model is as follows: the structure of pin for convenience detach on a kind of coupling, coupling (1) is circumferentially evenly equipped with one group of conical bore (1a), each conical bore (1a) coordinates with the conical surface at pin (2) middle part, it is characterized in that: the coupling (1) between adjacent two described conical bores (1a) has a tapped hole (1b), and these tapped holes are uniform along the circumference of coupling (1); The end face of described pin (2) little head end and the bulb end in contact of ejector pin (3), the shaft axis of the shaft axis of this ejector pin and pin (2) is on same straight line, and the blind hole drive fit on the roundlet shell of column of ejector pin (3) and pressing plate (4); The both sides of described pressing plate (4) have a screw via hole, the shaft axis of this screw via hole and the axis parallel of described pin (2), and after two attachment screws (5) are each passed through the upper corresponding screw via hole of pressing plate (4), connected with the upper corresponding tapped hole (1b) of described coupling (1).
Adopt above structure, the utility model makes pressing plate (4) and ejector pin (3) move together by tightening two attachment screws (5), thus the conical bore (1a) on the conical surface at pin (2) middle part and coupling (1) is disengaged, thus pin (2) of can dismantling quickly and easily, but this structure needs to tighten two attachment screws (5) and just to dismantle pin (2), operation or some inconvenience, adopt when being therefore specially adapted to narrow space.Dismantle after a pin (2), first pull down an attachment screw (5), then rotary pressure plate (4), after being rotated in place, then the attachment screw of dismantling (5) is loaded onto, to dismantle next root pin (2).
In order to ensure join strength, the specification of described attachment screw (5) is M20.
Beneficial effect: the utility model moves to make pressing plate by tightening two attachment screws together with ejector pin, thus the conical surface in the middle part of pin and the conical bore on coupling are disengaged, thus pin of can dismantling quickly and easily, but this structure needs to tighten two attachment screws and just to dismantle pin, operation or some inconvenience, adopt when being therefore specially adapted to narrow space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, the structure of pin for convenience detach on a kind of coupling, is formed primarily of coupling 1, pin 2, ejector pin 3, pressing plate 4 and attachment screw 5.Wherein, coupling 1 is circumferentially evenly equipped with one group of conical bore 1a, each conical bore 1a coordinates with the conical surface in the middle part of pin 2.Coupling 1 between adjacent two conical bore 1a has a tapped hole 1b, and these tapped holes 1b is uniform along the circumference of coupling 1, and these tapped holes 1b is distributed in circumferentially same, and is positioned at the outside of conical bore 1a.
The end face of the little head end of described pin 2 and the bulb end in contact of ejector pin 3, the shaft axis of this ejector pin 2 and the shaft axis of pin 2 are on same straight line, and the blind hole drive fit on the roundlet shell of column of ejector pin 3 and pressing plate 4.The number of described pressing plate 4 is one piece, and the both sides of this pressing plate 4 have a screw via hole, the shaft axis of this screw via hole and the axis parallel of described pin 2.After two attachment screws 5 are each passed through screw via hole corresponding on pressing plate 4, a tapped hole 1b corresponding with on coupling 1 is connected, and the specification of attachment screw 5 is M20.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
