SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the defects in the prior art and provides a hollow flange type supporter which is supported by oil pressure and supported by a pressing component and a plurality of springs in a buffering way.
The technical problem of the utility model is mainly solved by the following technical scheme:
a hollow flange supporter comprises a cylinder body, wherein a supporting rod for elastically supporting a workpiece is arranged in the cylinder body, the upper end of the supporting rod extends upwards to form the cylinder body, the lower end of the supporting rod extends downwards to form the cylinder body, a pressing assembly for movably holding the supporting rod is arranged on the outer wall of the supporting rod and arranged in the cylinder body, the pressing assembly comprises a conical sleeve which is attached to and sleeved with the supporting rod, a pressing sleeve is sleeved outside the conical sleeve in a hollow mode, and balls in rolling connection are arranged between the pressing sleeve and the conical sleeve; the cylinder body in be equipped with the oil inlet that promotes to compress tightly the cover and carry out the operation of holding tightly to the bracing piece.
Preferably, the pressing sleeve is elastically displaced downwards by oil pressure; the outer wall of the conical sleeve and the inner wall of the pressing sleeve are respectively conical surfaces, and the ball rolls along the conical surfaces.
Preferably, the upper part of the cylinder body is provided with an upper cover which is embedded with the cylinder body, the upper cover is respectively in compression joint distribution with the upper parts of the conical sleeve and the pressing sleeve, and the upper cover is in sleeve joint distribution with the supporting rod; the bottom of the cylinder body is provided with a rear cover, and the bottom of the rear cover and the bottom of the cylinder body are distributed on the same horizontal plane.
Preferably, a compression return spring is arranged between the outer wall of the compression sleeve and the cylinder body, and the compression sleeve is reset along the inner wall of the cylinder body through the compression return spring.
Preferably, the sealing rings are respectively sealed between the rear cover and the cylinder body, between the pressing sleeve and the cylinder body and between the upper cover and the cylinder body.
Preferably, the inner wall of the pressing sleeve is provided with an elastic retainer ring which is in contact with the balls.
The oil of oil inlet gets into to the cylinder body in, forms the oil pressure and promotes to compress tightly the downward elastic displacement of cover, carries out the brute force to the bracing piece and holds tightly, guarantees that the bracing piece possesses the holding power, the protection work piece. Establish the ball between tapered sleeve and compression sleeve, when the bracing piece has decurrent pressure, can play certain rigidity effect, to the dynamics of holding tightly of bracing piece great more, when the bracing piece received decurrent pressure, compress tightly the cover because compress tightly reset spring further dispersed decurrent power way, make support more steady, the effectual work piece of having protected.
The utility model provides a hollow flange supporter which is high in structure compactness, provides better supporting performance and further protects a workpiece.
