Resetting device using flexible positioning and rigid clamping in combination and positioning method thereof

Abstract

The invention relates to a resetting device using flexible positioning and rigid clamping in combination and a positioning method thereof. The invention is characterized in that a cartridge comprises two to four radially-arranged positioning gears, the lateral side of each positioning gear is provided with a positioning slant surface, Z-direction stopping planes are arranged between two adjacent positioning gears, a workpiece supporting board is provided with positioning slots fit with the positioning gears and positioning planes fit with the Z-direction stopping planes, a pop-rivet comprises a pop-rivet body which is connected with the workpiece supporting board by bolts, the pop-rivet orifices on the cartridge is provided with positioning cone surfaces, the lateral side of the pop-rivet body is provided with cone-shaped positioning contact planes fit with the positioning cone surfaces. The device can simultaneously realize precise resetting and rigid clamping, and ensure high safety and reliability of mechanical processing and high manufacture preciseness and efficiency of the processed object.

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 flexible positioning rigid clamping repeat positioning device and a positioning method that can be used in combination. Background technique: [0002] The connection device is most commonly used to clamp a connection with one or more workpieces. The workpiece is located at a precise position in the machining area of ​​the machine tool. The connection with the workpiece is the carrier or pallet of the workpiece. Chuck. [0003] Chinese patent CN1443620A discloses a connecting device. The device includes a chuck and a detachable workpiece holder clamp connected to the chuck. The workpiece holder with the clamping pin is fixed in the fixture of the chuck, the chuck is provided with a central hole and a clamping mechanism, the former is used to accommodate the clamping pin, and the latte...

AI Technical Summary

Problems solved by technology

The problem with this connecting device is that it can only be positioned in one direction in the X or Y directions. If simultaneous positioning in the X and Y directions is required, two or more connecting devices must be combined and used together, and the combined device High installation requirements

In this invention, the rigidity of the connection without the driving pin is often very low, and only small parts can be processed. At the same time, the driving pin is very easy to wear due to the wear and tear caused by friction.

[0005] To sum up, the disadvantage of the existing connection device is that it is difficult to realize the use of large and small parts on a set of universal fixtures at the same time, and at the same time ensure high rigidity and durability, especially the accuracy of repeated positioning and repeated positioning of circulation. hard to guarantee
