Abstract

The invention discloses a clamping device for a pedestal supporting column of a hydraulic punching machine. The clamping device for the pedestal supporting column of the hydraulic punching machine comprises a base and four pedestal columns, wherein a plurality of spring seams are formed in the outer wall of the bottom of each pedestal column; an arc-shaped side edge is arranged on the outward sidewall of each pedestal column. Through adoption of the structure that four clamping slots forming a cross-shaped structure are formed in the base, each pedestal column is mounted inside each clampingslot, a T slot adopting a T-shaped structure is formed in the middle part of the inner wall of each clamping slot and an arc-shaped slot adopting a semicircular structure is formed in the lower side of the T slot, and through cooperation of bulges arranged on the outer walls of the two sides of the bottom of each pedestal column, the pedestal columns can be stably clamped when the pedestal columnsare put into the clamping slots; in addition, lining bars with springs at the two ends are mounted inside the arc-shaped slots in the bottoms of the pedestal columns when the pedestal columns are clamped into the clamping slots, so that the effect of stabilizing the pedestal columns can be achieved, and moreover, the effects of resisting vibration and reducing pressure through the springs when the pedestal columns are impacted are achieved. Therefore, the clamping device effectively guarantees the stability of the supporting column of the punching machine.

Description

technical field

[0001] The invention relates to a clamping device, more precisely, a clamping device for a support column of a base of a hydraulic stamping machine. Background technique

[0002] The support column of the hydraulic press base is used to support the core components of the hydraulic press. In order to ensure the overall stability of the hydraulic press, it is often necessary to install a clamping device at the bottom of the support column to stabilize the support column. However, there are still some deficiencies in the existing clamping device used for the support column of the base of the hydraulic press machine. It only plays the role of fixing the support column, and it is still impossible to avoid the impact of the punching machine when the support column is supported. The force causes the position of the support column to shift, and there are also certain defects in the anti-seismic decompression. Contents of the invention
