Self-adaptive flexible clamp

Abstract

The invention discloses a self-adaptive flexible clamp which comprises a plurality of electromagnetic locking devices arranged in an array, wherein each electromagnetic locking device comprises a cylinder barrel assembly, a sliding assembly hermetically and slidably mounted in the cylinder barrel assembly in a fit manner, a magnet exciting coil arranged on the cylinder barrel assembly, a clampingpart connected to the sliding assembly and extending outside the cylinder barrel assembly and a magnetorheological fluid filling the cylinder barrel assembly. The sliding assembly at least divides thecylinder barrel assembly into two chambers in a sliding direction, an overflow channel through which the magnetorheological fluid flows in each chamber is arranged on the sliding assembly, and the magnet exciting coil controls the viscosity of the magnetorheological fluid, so that the sliding assembly is in a locked state or a sliding state. The clamp is designed as the electromagnetic locking devices by means of the magnetorheological fluid and the electromagnetic locking devices are combined to form the array clamp to clamp a precision workpiece with a complex surface contour. The self-adaptive flexible clamp is self-adaptive to various complex surface contours.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to an adaptive flexible clamp. Background technique [0002] Precision workpieces need to be clamped by fixtures during processing. Traditional clamping tools are not suitable for workpieces with complex curved surfaces. Therefore, when clamping workpieces with complex curved surfaces, the force is often uneven, which easily leads to insufficient clamping force, which makes the workpiece Displacement, or easy to cause excessive local clamping stress, deform the workpiece, reduce the accuracy of the workpiece, and even cause structural damage. In order to improve the above-mentioned technical defects, combined or assembled fixtures or casting mold fixtures are usually used to clamp such workpieces. However, there are many types of combined and assembled fixtures, and the assembly is complicated. One mold of the pouring mold fixture corresponds to one workpiece. , long processing cycl...

Problems solved by technology

[0002] Precision workpieces need to be clamped by fixtures during processing. Traditional clamping tools are not suitable for workpieces with complex curved surfaces. Therefore, when clamping workpieces with complex curved surfaces, the force is often uneven, which easily leads to insufficient clamping force, which makes the workpiece Displacement, or easily lead to excessive local clamping stress, deforming the workpiece, reducing the accuracy of the workpiece, and even causing structural damage

In order to improve the above-mentioned technical defects, combined or assembled fixtures or casting mold fixtures are usually used to clamp such workpieces. However, there are many types of combined and assembled fixtures, and the assembly is complicated. One mold of the pouring mold fixture corresponds to one workpiece. , long processing cycle and high cost;
