Problems solved by technology

However, this solution cannot clamp tiny parts, and the airbag only squeezes parts in one direction. For low-rigidity parts, one-way extrusion is easy to deform the part, and it is not suitable for non-destructive clamping of low-rigidity skeleton parts.

Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] The invention provides an air bag holder for non-destructive clamping of low-rigidity skeleton parts, see the attached figure 1 and 2 , including: sensor protection fixture 1, six-dimensional force sensor 2, adapter plate 3, air cavity seat 4, cage 6, air bag 8, force monitoring component and air circuit component;

[0034] The parts to be clamped are skeleton parts 7 with low rigidity, and the skeleton parts 7 are integrally formed, see attached image 3 , consisting of two coaxial rings and four support columns connecting the two rings;

[0035] The inside of the air cavity seat 4 is processed with a cylindrical cavity, forming a structure with one end open and one end closed, which plays the role of air path conduction. The lower end surface of the air cavity seat 4 is provided with threaded holes for fixing the air bag 8 And the cage 6, the u...

Abstract

The invention discloses an air bag clamping device used for lossless clamping of a low-rigidity framework type part and belongs to the technical field of microoperation and micro electro mechanical systems. The air bag clamping device comprises an air cavity seat, a holding frame, an air bag and an air way assembly. The air bag is of a structure with one end opened and one end closed, wherein the closed end of the air bag is provided with a cylindrical cavity concave inwards and a circular-ring-shaped cavity coaxial with the cylindrical cavity, the circular-ring-shaped cavity is used for being matched with a ring-shaped face of a framework type part, and the cylindrical cavity is used for being in shaft fit with the assembling position. The shape of the holding frame and the shape of the air bag are consistent, and one or more openings are machined in each of the two opposite circumferential faces of a circular-ring-shaped cavity of the holding frame. The opening end of the air cavity seat is in butt joint with the opening end of the air bag. The holding frame is arranged on the outer surface of the air bag in a sleeving manner and is fixed to the end face of the opening end of the air cavity seat. The air way assembly communicates with a cavity of the air cavity seat through an air pipe connector and is used for inflating and deflating of the air bag. By means of the air bag clamping device, the low-rigidity framework type to-be-assembled part can be extruded in double directions accurately in a lossless manner.

Description

technical field [0001] The invention belongs to the field of micro-operation and micro-electro-mechanical technology, and in particular relates to an air bag holder for non-destructive clamping of low-rigidity skeleton parts. Background technique [0002] At present, low-rigidity skeleton parts are more and more used in the field of high-tech micro-miniature technology. For example, copper alloy skeleton parts with an inner diameter of 26mm, an outer diameter of 28.5m, a height of 11mm, and four support columns with a width of 2mm in the middle, Lossless clamping is an urgent problem to be solved. In addition, for low-rigidity skeleton parts, the fit gap is small and needs to be glued during assembly. How to ensure precise assembly and uniform fit gap requires monitoring the assembly process. In order to complete the non-destructive clamping and precision assembly of low-rigidity skeleton parts , it is urgent to develop a flexible gripper with multi-dimensional force monito...
