Abstract
The utility model relates to a novel lathe pneumatic-hydraulic dual-purpose chuck, wherein a proper amount of hydraulic cylinders and pistons are arranged on the chuck, both ends of a spindle type lever are respectively connected with the piston and a chuck jaw, a clamping jaw is pushed by the piston through the spindle type lever under the action of gas or liquid pressure to clamp a workpiece, the gas or liquid pressure is removed, and the piston is reset under the action of the elastic force of a spring to release the clamping force for the workpiece; holes are drilled on a joint sleeve and communicated with the hydraulic cylinders through corresponding passages; a rotary joint is connected with the joint sleeve, so that the gas or liquid pressure is provided for the piston of each hydraulic cylinder through pipelines on the rotary joint and the joint sleeve under the condition of rotating the chuck; and in order to position and restrict the spring, a plug cap is arranged at the mouth of a cylinder body where the piston is positioned, and the process plug cap can close relevant paths to prevent the leakage of pressure air or pressure liquid.
Description
Technical field
The utility model relates to a kind of lathe chuck, and particularly a kind of novel pneumatic-hydraulic dual-purpose lathe chuck belongs to the mechanical ﹠ electrical technology field.
Background technology
Chuck is the indispensable annex of lathe metal cutting, at present, mostly the clamping power of chuck is to come to manpower or two aspects of electric power, end user's masterpiece is that its labour intensity of power is big and efficient is lower, though its chuck clamping force of electrification is big, but the structure of its chuck is comparatively complicated, because electrification is used as power, its security performance is also lower.
Summary of the invention
The purpose of this utility model is that a kind of novel pneumatic-hydraulic dual-purpose lathe chuck will be provided, and the simple clamping force of this chuck structure is big, and it can overcome the deficiency of present manpower or electric chuck existence effectively.
The end scheme that its technical problem that solves the utility model adopts is achieved in that and is provided with an amount of hydraulic cylinder and piston on chuck, the two ends of spindle-type lever link to each other with chuck jaw with piston respectively, piston can clamping work pieces by spindle-type lever pushing claw under the effect of gas or fluid pressure, remove gas or fluid pressure, piston resets under the effect of spring force and loosens clamping force to workpiece; Have the hole on the fitting sleeve and communicate with hydraulic cylinder by corresponding passage; Swivel joint links to each other with fitting sleeve, so, can provide gas or fluid pressure by the pipeline on swivel joint and the fitting sleeve to the piston of hydraulic cylinder under the situation of chuck rotation; For location and constraint to spring, be provided with blanking cover at the oral area of piston place cylinder body, the technology blanking cover can seal relevant path to prevent the leakage of pressure air or pressure fluid.
Operation principle of the present utility model is: owing to be provided with an amount of hydraulic cylinder and piston on chuck, the two ends of spindle-type lever link to each other with chuck jaw with piston respectively, piston passes through spindle-type lever pushing claw and clamping work pieces under the effect of gas or fluid pressure, remove gas or fluid pressure, piston resets under the elastic force effect of spring and loosens clamping force to workpiece.
The beneficial effects of the utility model are: this structure is utilized the effect of air pressure or hydraulic pressure to promote piston and is driven catching and step up or loosen the power of stepping up to workpiece; Manpower that it uses with lathe or electric power chuck compare that to have clamping force simple in structure big, characteristics, so, can overcome the problem of available man-power chuck and electric chuck existence effectively.
Description of drawings
Below in conjunction with accompanying drawing structure of the present utility model is described further.
Fig. 1 is a structure principle chart of the present utility model.
Shown in the figure: 1 chuck; 2 pistons; 3 springs; 4 blanking covers; 5 spindle-type levers, 6 claws; 7 is top; 8 fitting sleeves; 9 swivel joints; 10 technology blanking covers.
The specific embodiment
On chuck (1), be provided with an amount of hydraulic cylinder and piston (2), the two ends of spindle-type lever (5) link to each other with chuck jaw (6) with piston (2) respectively, piston (2) promotes claw (6) by spindle-type lever (5) and can clamping work pieces under the effect of gas or fluid pressure, remove gas or fluid pressure, piston (2) resets under the effect of spring (3) elastic force and loosens clamping force to workpiece; Have the hole on the fitting sleeve (8) and communicate with hydraulic cylinder by corresponding passage; Swivel joint (9) links to each other with fitting sleeve (8), so, can provide gas or fluid pressure by the pipeline on swivel joint (9) and the fitting sleeve (8) to the piston (2) of hydraulic cylinder under the situation of chuck (1) rotation; For location and constraint to spring (3), be provided with blanking cover (4) at the oral area of piston (2) place cylinder body, technology blanking cover (10) can seal relevant path to prevent the leakage of pressure air or pressure fluid.
