Technical field
The utility model relates to a kind of vertical type fixed hydraulic power chuck, and brills such as main and numerical control machining center mill coordinative composition of equipments, and cylinder block is linked to each other with chuck, save the oil distributing valve device, belong to the machine tool accessories technical field.
Background technology
In prior art, comparatively close with the utility model is power chuck and angling cylinder system.Common pneumatic (or surging) chuck is contained in the main shaft of numerical control machine tool head, and cylinder (or oil cylinder) is contained in afterbody, and the two couples together with pull bar, by moving axially of piston chuck jaws is produced and moves radially, with pine folder workpiece.Because power chuck is two parts of separating with angling cylinder, cause whole clamping system self length longer, and brills such as machining center mill the automatic fixture that equipment needs compact conformation, so general power chuck and angling cylinder system can't be equipped in brills such as numerical control machining center and mill on the equipment.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of automatic clamping system of compact conformation, by several these system clamps being fixedly installed in the equipment that mills that bores, it is fast to save time, reaching the purpose of quick die change, is a kind of vertical type fixed hydraulic power chuck of enhancing productivity.
According to the technical scheme that the utility model provides, vertical type fixed hydraulic power chuck comprises chuck body, wedge-catch system, door, three claws, three slides, six T type pieces, cylinder body, piston, base, the axis of guide; Described chuck body, door connect forms chuck main body, offer three straight troughs at the chuck body front end, article three, three slides are installed in the straight trough, three slides connect with wedge-catch system by skewed slot, three slides are connected with three claws by broach outside the disk body front end face, and fix by six T type pieces and three claws, and connect with wedge-catch system with the claw mounting screw; Feature is: cylinder body and base are formed the oil cylinder main body, and piston is installed in the cylinder body, and slides in cylinder body along axis of guide direction, and lower oil cavitie in the formation up and down of piston, the control hydraulic oil of last lower oil cavitie are by left side turnover oilhole or the control of right turnover oilhole; Described piston links to each other by driving attachment screw with wedge-catch system, and under the drive of piston, wedge-catch system slides up and down in chuck body; Chuck body and cylinder body are fixedly connected with joint bolt is seamless.
Be provided with seal ring seal between described cylinder body and the base; Be provided with seal ring seal between described cylinder body and the piston;
Described wedge-catch system front end and three slide contact positions are provided with skewed slot, and sliding in the front and back of wedge-catch system to convert moving radially of claw to.
Described cylinder body cylindrical is provided with left side turnover oilhole or right turnover oilhole.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; This vertical type fixed hydraulic power chuck is linked to be an integral body with cylinder body and chuck, is loaded on the work top, and clamping workpiece is convenient, can realize quick die change, can reduce labor intensity greatly, shorten clamping time, boost productivity, and clamping force can adjust, be fit to match with numerical control machining center.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure vertical view.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
