Quickly assembled chuck

Abstract

The invention discloses a quickly assembled chuck. The quickly assembled chuck comprises a main body and a carrier, wherein the carrier can be attached to the main body, and is fixedly provided with apop rivet; a first pin hole and a second pin hole are formed in the carrier, and cross sections of the first pin hole and the second pin hole are non-circular along a vertical direction; the main body is provided with a slot along a vertical direction; the pop rivet can be inserted in the slot and is connected with a buckle structure in the slot in a fastened manner; a buckle driving device can drive the buckle structure and the pop rivet to be fastened or unfastened; a fixing pin of which the cross section is non-circular is fixedly arranged on the main body; the fixing pin can be inserted in the first pin hole in a locking manner in a peripheral direction; an inclined hole buoyancy lifting pin is slidably inserted in an inclined hole in the main body, and can extend out of the inclinedhole by a certain height; the cross section of the upper end of the inclined hole buoyancy lifting pin has a non-circular structure; a buoyancy lifting pin driving device drives the inclined hole buoyancy lifting pin to slide; and the inclined hole buoyancy lifting pin can be inserted in the second pin hole in a locking manner in a peripheral direction. By the quickly assembled chuck, machining and manufacturing are facilitated, clamping and positioning speed is high, positioning is accurate, the positioning cost is reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a quick clamping chuck suitable for high-precision product processing. Background technique [0002] Products with small size and high machining accuracy are generally installed on the carrier first, and then the carrier is installed on the processing machine tool by means of screws. The carrier installation efficiency is low, and the positioning accuracy after installation is low. Long-term use After wear, the positioning accuracy will be reduced, resulting in low processing accuracy of the product. At present, there is also a structure that achieves rapid positioning through cylindrical pins on the carrier and the workbench of the extra bed, and then tightens and fixes it through the connecting piece. However, if this structure is cylindrical If the gap between the pin and the pin hole is large, the carrier will shake on the horizontal plane. If the gap between the cylindrical pin and the p...

Problems solved by technology

[0002] Products with small size and high machining accuracy are generally installed on the carrier first, and then the carrier is installed on the processing machine tool by means of screws. The carrier installation efficiency is low, and the positioning accuracy after installation is low. Long-term use After wear, the positioning accuracy will be reduced, resulting in low processing accuracy of the product. At present, there is also a structure that achieves rapid positioning through cylindrical pins on the carrier and the workbench of the extra bed, and then tightens and fixes it through the connecting piece. However, if this structure is cylindrical If the gap between the pin and the pin hole is large, the carrier will shake on the horizontal plane. If the gap between the cylindrical pin and the pin hole is too small, it will be difficult to quickly clamp and use.
