Cylinder clamping frame

Abstract

The invention provides a cylinder clamping frame which comprises a clamping platform and a clamping base fixedly arranged on the upper surface of the clamping platform. A V-shaped clamping groove withan upward opening is formed in the clamping base. Supporting bases are symmetrically arranged on the two sides of the clamping base and perpendicularly fixed to the clamping platform. A clamping armis slidingly arranged on the supporting base on each side in the horizontal direction. An inclined clamping face is arranged on the inner end face of each clamping arm. The clamping faces on the two sides form a reversed V shape. The outer end face of the clamping arm on each side is rotationally provided with the upper end of a driving arm. The middle of each driving arm is rotationally connectedwith the supporting base on the corresponding side. The bottom of the clamping platform is slidingly provided with a first sliding rod and a second sliding rod in the horizontal direction. The lowerends of the driving arms on the two sides are hinged to one end of the first sliding rod and one end of the second sliding rod correspondingly. Driving mechanisms for driving the ends, connected withthe lower ends of the driving arms, of the two sliding rods to synchronously get close to get away are arranged between the clamping platform and the first sliding rod and between the clamping platform and the second sliding rod.

Description

Technical field [0001] The invention relates to a cylindrical clamping frame. Background technique [0002] In the prior art, when processing a cylindrical workpiece, it needs to be clamped and positioned by a special fixture. However, the current practical fixture usually includes a first card seat and a second card seat. The first card seat and the second card seat are respectively A V-shaped positioning groove is provided, and the first card seat is fixedly arranged, and the second card seat is slid or rotated. When positioning, the cylindrical workpiece is placed in the V-shaped positioning groove of both the first card seat and the second card seat In this way, the cylinder is positioned and clamped by the four sections of the cylinder. The stability is good. However, there is a defect that a set of special fixtures can only be used for cylindrical workpieces of one diameter. Diameter workpieces need to be equipped with different sizes of fixtures, so the versatility is poo...
