The magic chuck device
The utility model relates to the very simple magic chuck device of a kind of grip device, particularly structure.
At present, the clamping control system that forms by hydraulic power unit, hydraulic jack of known magic chuck (or mould) device.But, its structure more complicated, reliability is low, and cost is high.
Summary of the invention
Complicated in order to overcome existing magic chuck (or mould) apparatus structure, the deficiency that cost is high, the utility model provides a kind of magic chuck (or mould) device, can make magic chuck (or mould) device very simple.
The utility model solves the technical scheme that its technical problem adopted: clamp fixing plate is fixed by bolts on the platen; Drift is fixed on the cylinder piston rod; Drift and cylinder are fixed on the cylinder holder; The cylinder holder is fixed on the clamp fixing plate; Fixing 2 alignment pins on the clamp fixing plate, 2 magic chuck bodies are through lining on it and alignment pin matched in clearance location; Drive drift through cylinder again, inclined-plane and the inclined-plane on the magic chuck body on the drift are interacted, clamp the magic chuck body; Workpiece is fixed on the magic chuck body; The workpiece that clamps when 1 magic chuck body band and on lathe, add man-hour, 1 magic chuck body good workpiece to be processed of workpiece, clamping of utilizing unload this process time to have processed is waited for upward machine tooling in turn in addition; Reach the purpose of quick replacing anchor clamps.
The beneficial effect of the utility model is both need not increase hydraulic system and just can accomplish the reliable anchor clamps of changing fast.Make the magic chuck system more simple, significantly reduce cost.
