Positioning device with flexible structure and positioning method of positioning device

Abstract

The invention discloses a positioning device with a flexible structure and a positioning method of the positioning device. The positioning device with the flexible structure is placed on a clamping disc, the positioning device with the flexible structure is in contact with the positioning bevel of a positioning tooth through the groove edge of a positioning groove 5, and a small gap is kept between the Z positioning surface 3 of the positioning device with the flexible structure and the Z positioning surface of the clamping disc; and a threaded through hole is formed in the middle of the positioning device with the flexible structure, a pull nail is mounted in the threaded through hole, a tensioning device is used to pull the nail, the positioning device moves towards the direction of theclamping disc until the Z positioning surface of the clamping disc is closely attached to the Z positioning surface 3 of the positioning device with the flexible structure, a U-shaped notch 10 is deformed in the moving process of the direction of the groove bottom of the positioning groove 5 of the positioning device with the flexible structure to the positioning tooth, the opening in the bottom of the positioning groove is expanded, the part below the U-shaped 10 notch on the positioning bevel of the positioning groove 5 is closely fitted with the positioning bevel of the positioning teeth, and the positioning teeth are clamped. The high precision positioning of the positioning device with the flexible structure and the clamping disc is realized.

Description

technical field [0001] The invention relates to the technical field of positioning and clamping between a machine tool and a workpiece in precision machinery manufacturing, in particular to a positioning device with a flexible structure and a positioning method thereof. Background technique [0002] If the devices in the prior art need to be positioned in two directions at the same time, it is necessary to combine two or more connecting devices for use together, and the installation requirements of the combined devices are high. And it is only suitable for medium and large parts with low precision. Secondly, because the above-mentioned positioning is a rigid positioning, the clamping pin and the center hole wear a lot, and the service life is low. There are also disadvantages in the prior art that the area of ​​the finished surface is large, the processing is difficult and the cost is high, and the stress concentration will be generated when the avoidance groove is deformed,...

Problems solved by technology

[0002] If the devices in the prior art need to be positioned in two directions at the same time, it is necessary to combine two or more connecting devices to use together, and the installation requirements of the combined devices are high

And it is only suitable for medium and large parts with low precision. Secondly, because the above positioning is rigid positioning, the clamping pin and the center hole wear a lot, and the service life is low

There are also disadvantages in the prior art that the finishing surface area is relatively large, the processing is difficult and the cost is high, and the avoidance groove will generate stress concentration when deformed, which will affect the service life

[0003] In summary, the disadvantages of the existing devices are that the finished surface area is large and the processing is difficult; when the tensioning device is working, it will easily cause wear or stress concentration during the simultaneous positioning and assembly process, which will affect the service life of the pallet
