Micro flexible positioning locking mechanism

Abstract

The invention discloses a micro-motion flexible positioning and locking mechanism, which is used for the positioning and locking of micro parts in micro assembly. The positioning and locking mechanism is composed of three parts: an elastic positioning and locking component (1), a jacking bolt (2) and a fixing bolt (3) for positioning the micro-movement flexible positioning and locking mechanism with the turntable base (4); The positioning locking part (1) is composed of a V-shaped top block (A), an elastic connection block (B), a force transmission block (C), a fixed block (D), a flexible arm (E) and a bolt hole (F); V The top block (A) is connected with the assembled micro parts (5); the fixed block (D) is distributed on both sides of the force transmission block in a wing shape, and has four bolt holes (F); the flexible arm (E) is connected to the force transmission block. block (C) and fixed block (D). The effect and benefit of the present invention are integrated design, simple structure and one-time molding during processing. The V-shaped top block design makes the force more uniform. The leaf spring structure of the elastic connection block improves the assembly accuracy.

Description

technical field [0001] The invention belongs to the technical field of micro-assembly, and relates to a micro-motion flexible positioning and locking mechanism, which is used for positioning and locking micro parts in micro-assembly. Background technique [0002] With the rapid increase in the demand for alignment operations in industrial production and scientific research, it has become an important research field to develop automated and semi-automated micro-assembly systems to free operators from intensive, boring and tedious micro-operations. [0003] The manufacture and assembly of miniature parts requires that the miniature positioning locking mechanism has a compact structure, small dimensions, and can output sufficient clamping force and locking force. Due to the difference in the actual size of the assembled parts and the positioning error of the assembly equipment, it is necessary for the device to be able to adapt to the operated micro-parts and have a certain deg...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the existing flexible positioning and locking mechanism has a complex structure, and the locking and positioning functions are usually composed of multiple components.

In micro-assembly, the assembly accuracy of each component will greatly affect the clamping consistency of micro-parts, which restricts the improvement of micro-assembly accuracy.

At the same time, the realization of flexibility requires outer lining materials, and the contact surface of the jig for assembly of small parts is usually very small, which makes this method not suitable for micro-assembly operations
