Abstract

The invention provides a pneumatic self-adaptive clamp and a using method thereof.The pneumatic self-adaptive clamp comprises a left clamp base body, a right clamp base body and at least one pair of clamping contacts, the left clamp base body and the right clamp base body are provided with the same number of clamping contact mounting holes, and the clamping contact mounting holes in the left clamp base body and the right clamp base body are arranged in a one-to-one opposite mode; two clamping contacts in each pair of clamping contacts are installed in two opposite clamping contact installation holes in the left clamp base body and the right clamp base body respectively, a clamping air cylinder is arranged at the rear end of each clamping contact, the two clamping air cylinders at the rear ends of each pair of clamping contacts form a pair of clamping air cylinders, and the clamping air cylinders are connected with a pneumatic system. The pneumatic system independently drives each pair of clamping cylinders to work, and enables the clamping contacts to extend out one by one from a point with high rigidity to a point with low rigidity under the driving of low-pressure gas according to the rigidity of each clamped point on a clamped piece, so that the deformation of the clamped piece caused by the contact between the clamping contacts and the clamped piece is avoided.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a pneumatic self-adaptive clamp and a method for using the same. Background technique [0002] When the workpiece is subjected to machining such as cutting and polishing, in order to prevent the workpiece from shaking during the machining process, a corresponding fixture is often required to fix the workpiece. In the production process of aero-engine, the large fan blade of aero-engine, as an important part in the engine to propel the aircraft forward, requires a series of mechanical processing. For precision thin-walled workpieces such as large-scale fan blades of aero-engines, because the thickness of the clamped point on the workpiece is very thin, and the rigidity of different positions on the workpiece is different, it is easy to be clamped during the clamping process. deformation due to uneven stress. Therefore, it is necessary to design a pneumatic adaptive clamp, which c...
