Abstract

The invention provides a device for repeatedly positioning a workpiece and retaining the free form of the workpiece. The device comprises retainers (2), and each retainer (2) includes a first clamping piece (12), a second clamping piece (13) and a third clamping piece (14) which are tightly and fixedly connected with one another. The invention further provides a method for repeatedly positioning the workpiece and retaining the free form of the workpiece. According to the device for repeatedly positioning the workpiece and retaining the free form of the workpiece, during the multiple times of clamping, the workpiece is mechanically connected with a tool, the relative position is fixed, the tool and a machining actuating station such as a manipulator are connected through a zero point positioning system, and thus, the effect that the repeatedly installed workpiece is consistent with the machining actuating station in posture can be ensured.

Description

technical field [0001] The invention relates to a clamping device, in particular to a free-form holding device for repetitively positioned workpieces. Background technique [0002] In some mechanical processing and assembly processes, based on space, economy, and technical realization factors, the processing execution end (such as a manipulator) completes each process in sequence, and sometimes the same workpiece needs to be clamped repeatedly, requiring the processing execution end and the workpiece to be clamped multiple times. Maintain a fixed relative position, that is, a positioning relationship. When the workpiece is a bellows workpiece, due to the lack of positioning structure of the bellows, it is difficult to ensure the relative positioning of the processing execution end and the workpiece in multiple clampings. In addition, the bellows itself has poor rigidity, and additional stiffness needs to be enhanced during processing. Therefore, it is necessary to enhance t...
