Abstract

The invention relates to a vertical type fixed hydraulic power chuck which comprises a chuck body, a wedge catch system, a blocking cover, three claws, three slide carriages and six T-shaped blocks, and is characterized in that an oil cylinder body and a base form an oil cylinder main body; a piston is installed in the oil cylinder body and slides in the oil cylinder body along the direction of aguiding shaft; an upper oil chamber and a lower oil chamber are formed above and below the piston; the control hydraulic oil of the upper oil chamber and the lower oil chamber is controlled by a leftoil inlet and outlet hole or a right oil inlet and outlet hole; the piston is connected with the wedge catch system by a driving connecting screw; under the driving of the piston, the wedge catch system slides up and down in the chuck body; and the chuck body is connected seamlessly and fixedly with the oil cylinder body by a connecting bolt. The structure of the invention is simple, compact and reasonable, the vertical type fixed hydraulic power chuck connects the cylinder body and the chuck integrally and is loaded on a work bench, a workpiece can be loaded and clamped conveniently, and quick die changing can be realized, thereby greatly lightening the labor intensity, shortening the clamping time, improving the productivity, having adjustable clamping force, and being suitable for matching with a numerical control machining center.

Description

technical field [0001] The invention relates to a vertical fixed hydraulic power chuck, which is mainly matched with drilling and milling equipment such as a numerical control machining center, connects an oil cylinder body and the chuck, saves an oil distribution valve device, and belongs to the technical field of machine tool accessories. Background technique [0002] In the prior art, the power chuck and the rotary cylinder system are relatively similar to the present invention. The usual pneumatic (or hydraulic) chuck is installed at the head of the spindle of the CNC machine tool, and the cylinder (or oil cylinder) is installed at the tail. To loosen the workpiece. Since the power chuck and the rotary cylinder are two separate parts, the length of the entire clamping system itself is longer, and drilling and milling equipment such as machining centers require compact automatic fixtures, so the general power chuck and rotary cylinder system cannot Equipped on drilling...
