A flexible fixture with integrated assembly force detection

Abstract

The invention belongs to the technical field of processing and manufacturing, and particularly relates to a flexible clamp capable of avoiding assembly damage of a thin-walled workpiece with a sealingstructure inside. A pressure sensor is arranged on the flexible clamp to measure the assembly force of the workpiece during an assembly process, so as to indirectly monitor the assembly condition ofthe internal sealing structure and to prevent the sealing structure inside the workpiece from being damaged by assembly. In addition, a multi-dimensional force sensor is arranged on the clamp to measure the stress of a clamped point of the thin-walled workpiece, and an electric cylinder is controlled to make the clamping force in a proper range to prevent the thin-walled workpiece from being crushed. The flexible clamp comprises a clamp A (1), a clamp B (2), a supporting tooling (3) and a mounting base. The clamp A (1) and the clamp B (2) are arranged on the base. The supporting tooling (3), the clamp A (1) and the clamp B (2) are used in conjunction. The clamp A (1) comprises an electric cylinder (1.1), a three-dimensional force sensor (1.2), a clamp upper cover (1.3), a support column (1. 4) and a clamp A base (1.5).

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing, and in particular relates to a flexible fixture for integrated assembly force detection. Background technique [0002] A flexible fixture with integrated assembly force detection in the present invention is used on a high-reliability assembly device, and cooperates to realize the automatic assembly of large-size components of the servo mechanism. [0003] There are multiple sealing structures inside the large-size components of the servo mechanism. During the press-fitting process, it is necessary to monitor the assembly force of the workpiece and the force in other directions of the workpiece to judge the assembly quality of the workpiece and whether the sealing ring is damaged; secondly, there are Thin-wall shaft hole parts have higher requirements on clamping force. In addition, large-size components are mainly hole-shaft workpieces, but the size span is large, and the fi...

Problems solved by technology

In addition, large-size components are mainly hole-shaft workpieces, but the size span is large, and the fixture needs to have certain versatility

[0004] At present, the fixtures for shaft and hole parts are commonly used as special fixtures. More commonly, there are three-jaw chucks plus mandrel fixing or sleeve fixing. They are mainly used in mechanical processing and can adapt to the clamping of shaft and hole workpieces within a certain size range. Tight positioning, but unable to measure and control the clamping force; the fixtures for small and large shaft and hole parts generally use mechanical clamps or adsorption clamps, which have strong adaptability
