Rapid clamping and precise positioning device and method thereof

Abstract

The invention provides a rapid clamping and precise positioning device. The rapid clamping and precise positioning device comprises a positioning and clamping part (1), a workpiece clamping part (2) and a connecting mechanism. The positioning and clamping part (1) comprises a zero point positioning pin (5), and has a rapid, repeated and precise positioning function; and the workpiece clamping part(2) comprises two flaps of open-close type clamping pieces, and the tightening degree is adjusted through a rotary knob. According to a method of the rapid clamping and precise positioning device, repeated and rapid clamping and precise positioning of a thin-walled bent pipe are achieved, the clamping and dismounting efficiency is high, the response speed is high, and the repeated positioning precision is high; and automatic positioning and rapid and repeated clamping can be achieved under the effect of a mechanical arm, the structural adaptability is high, and rapid and repeated clamping andhigh-precision repeated positioning of the thin-walled bent pipe are achieved.

Description

technical field [0001] The invention relates to a clamping device, in particular to a quick clamping and precise positioning device and a method thereof. 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 tubular workpiece, it is often difficult to ensure the relative positioning of the processing execution end and the workpiece in multiple clampings due to the lack of positioning design of the tubular workpiece itself. However, designing a high-precision positioning structure in the tubular workpiece cannot be realized through the existing forming pr...

When the workpiece is a tubular workpiece, it is often difficult to ensure the relative positioning of the processing execution end and the workpiece in multiple clampings due to the lack of positioning design of the tubular workpiece itself

However, designing a high-precision positioning structure in the tubular workpiece cannot be realized through the existing forming processes of the tubular workpiece, such as pipe bending, half-side press welding, expansion, and drawing.
