Abstract
The utility model relates to a novel pneumatic/hydraulic dual-purpose chuck of a lathe. The inner side of a hydraulic cylinder on a chuck body is provided with a piston, both ends of a spindle type lever are respectively connected with the piston and a jaw, and the piston pushes the jaw to clamp a workpiece by the spindle type lever under the push of the pressure of gas or liquid and resets under the action of the elastic force of a spring by removing the pressure of the gas or the liquid to loosen the clamping of the workpiece; a rotary joint is connected with a joint sleeve, which ensures that the chuck can ensure that the pressure of the gas or the liquid of the outside is connected with the hydraulic cylinder in the chuck at any moment under the condition of rotation; a hole is arranged on the joint sleeve and is communicated with the hydraulic cylinder by a passage; in order to position and restrict the spring, an opening part of a cylinder body in which the piston is arranged is provided with a blocking cover; and the technological blocking cover aims at blocking the relevant passage, which prevents the leakage of compressed air or compressed 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 metal turning lathe, at present, and in the product of chuck, the power resources of its clamping mainly are manpower and two kinds of main method of electric power, end user's masterpiece be the chuck of power because the restriction of people's strength generally is used on the middle-size and small-size lathe, use this chuck labour intensity big and efficient is lower, though the chuck clamping force of electrification is big, efficient is also higher, but its chuck structure is complicated, and cost is higher, because electrification is used as power, its security performance is also lower.
Summary of the invention
The purpose of this utility model is: provide a kind of with hydraulic pressure or the air pressure chuck as power, this chuck has simple in structure, low price, and clamping force is big, the high characteristics of efficient, it can overcome deficiency that available man-power chuck and electric chuck exist and effective effectively.
The technical scheme that its technical problem that solves the utility model adopts is achieved in that it is made up of chuck body, piston, spring, blanking cover, spindle-type lever, claw, top, fitting sleeve, swivel joint, technology blanking cover, piston is equipped with in hydraulic cylinder inboard on chuck body, the two ends of spindle-type lever link to each other with claw with piston respectively, piston passes through spindle-type lever pushing claw clamping work pieces under the promotion of gas or fluid pressure, remove gas or fluid pressure, piston resets under the elastic force effect of spring and loosens clamping to workpiece; Swivel joint links to each other with fitting sleeve, guarantees that chuck can guarantee at any time that under the situation of rotation extraneous gas or fluid pressure link to each other with hydraulic cylinder in the chuck; Have the hole on the fitting sleeve and communicate with hydraulic cylinder by passage; For location and constraint to spring, be provided with blanking cover at the oral area of piston place cylinder body, the purpose of technology blanking cover is to shut related pathways, prevents the leakage of pressure air or pressure fluid.
The beneficial effects of the utility model are: because piston passes through spindle-type lever pushing claw clamping work pieces under the promotion of gas or fluid pressure, so clamping force is big, the efficient height can have the problem of improving present manpower chuck and electric chuck existence.
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 body, 2 pistons, 3 springs, 4 blanking covers, 5 spindle-type levers, 6 claws, 7 top, 8 fitting sleeves, 9 swivel joints, 10 technology blanking covers.
The specific embodiment
Piston (2) is equipped with in hydraulic cylinder inboard on chuck body (1), the two ends of spindle-type lever (5) link to each other with claw (6) with piston (2) respectively, piston (2) promotes claw (6) clamping work pieces by spindle-type lever (5) under the promotion of gas or fluid pressure, remove gas or fluid pressure, piston resets under the elastic force effect of spring (3) and loosens clamping to workpiece; Swivel joint (9) links to each other with fitting sleeve (8), guarantees that chuck can guarantee at any time that under the situation of rotation extraneous gas or fluid pressure link to each other with hydraulic cylinder in the chuck; Have the hole on the fitting sleeve (8) and communicate with hydraulic cylinder by passage; For location and constraint to spring (3), be provided with blanking cover (4) at the oral area of piston (2) place cylinder body, the purpose of technology blanking cover (10) is to shut related pathways, prevents the leakage of pressure air or pressure fluid.
