A clamping device and clamping method for self-centering adjustable machine

Abstract

The invention relates to a clamping device for self-centering and adjustable machines, comprising a base plate (1) and a plurality of sets of clamping toolings arranged on the base plate, each assembled clamping tooling includes an upper pressing plate (2), a lower pressing plate (6) ), upper positioning block (10), forward and reverse screw (11), polished rod (12) and lower positioning block (15); forward and reverse screw (11) and polished rod (12) are arranged side by side and pass through sequentially from top to bottom Passing through the upper positioning block (10), the upper pressing plate (2), the lower pressing plate (6), and the lower positioning block (15), the present invention effectively solves the problem of wing and rudder parts by using a self-centering adjustable machine to add a clamping device The problem of too long preparation time for clamping and processing also solves the problem that the deformation of the parts leads to the difficulty of clamping, and the alignment accuracy cannot be guaranteed, which greatly improves the clamping efficiency, while the clamping is firmer and the accuracy and reliability are further improved.

Description

technical field [0001] The invention belongs to the field of mechanical clamping, in particular to a clamping device and a clamping method for a self-centering adjustable machine. Background technique [0002] Wing parts and rudder surface parts, the shape surface is aerodynamic shape structure, the curvature of the surface is complex, the use of machined general pressure plate and jack to clamp parts, the parts alignment adjustment time is long, the adjustment is inconvenient and other problems make the parts clamp to find The positive time is difficult to control, and the processing efficiency of the parts is difficult to guarantee. At the same time, the wing and rudder parts often cause large deformation of the parts under the action of welding force and heat, and even the deformation of individual parts can reach 4mm. The original clamping tool adopts rigid connection. When the deformation of the product is large, it is often difficult to adjust the clamping position of ...
