Barrel close mouth fixture

Abstract

The invention discloses a barrel close mouth fixture, which comprises a left bracket [1], a right bracket [10] and a close mouth screw rod mechanism. The center of the left bracket [1] and the center of the right bracket [10] are provided with an axial hole [15] respectively; the close mouth screw rod mechanism comprises a close mouth screw rod [3], a left-hand nut [4] and a right-hand nut [9], and the turning directions of threads at both ends of the close mouth screw rod [3] are opposite; the left-hand nut [4] and the right-hand nut [9] are positioned in the axial holes [15] of the left bracket and the right bracket respectively; the corresponding positions on the left bracket [1] and the right bracket [10] are provided with radial holes respectively; the left-hand nut [4] and the right-hand nut [9] are provided with a rotating shaft [2] respectively; the rotating shafts [2] are positioned in the radial holes; the other end of the left bracket [1] and the other end of the right bracket [10] are provided with a jaw [5] respectively; the side walls of the jaws [5] are provided with screw holes; and fastening screws are arranged in the screw holes. The fixture has the advantages ofconvenient adjustment, improvement on production efficiency, and high quality during barrel welding.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp for closing a cylinder after being rolled by a plate rolling machine. Background technique [0002] Cylindrical metal components (referred to as cylinders) are widely used in factories, such as metal flues, alloy shells, etc. The cylinder is cylindrical and is formed by welding the interface after being rolled by a plate rolling machine. In the process of rolling seam butt joint, due to factors such as equipment and human factors, it is difficult to make an accurate seam joint butt joint at one time. The common situation is that there is a high and low error in the seam joint, and there is an up and down deviation on the joint surface. The commonly used adjustment method is to tap with a hammer or gradually adjust with tools such as crowbars. First spot welding is in place, and then continuous welding. The disadvantages of the above adjustment method are: it is easy to cause local unevenness ...
