Abstract
The utility model discloses a hydraulic chunk and belongs to drill carriage matching parts. The hydraulic chunk is composed of a clamping tile base, a chunk base, screws, a sealing ring, a cover plate, a sealing ring, a clamping tile, a steel wire baffle ring, a pressing plate, screws, screws, a wear-resisting ring, a sealing ring, a piston, springs and a piston base. The clamping base is connected with the pressing plate through the screws to form a rectangular slide, and the clamping tile is arranged in the slide and can perform in linear motion; four piston cavities are arranged in the clamping tile base, and the piston can perform linear motion in the clamping tile base; the chunk base is connected with the cover plate through the screws; the steel wire baffle ring is arranged in an inner-wall groove of the clamping tile; and the screws are used for connecting the pressing plate and the piston base, and a plurality of springs are respectively arranged between the piston and the piston base. The hydraulic chunk solves the problem that the existing normally-opened hydraulic chunk adopts a rubber sleeve which is damaged or leak oil easily, and failure of the chunk can be caused.
Description
Technical field
The utility model belongs to the drill carriage auxiliary component, is specifically related to a kind of oild chuck.
Background field
Before the utility model was made, traditional chuck of often opening was rubber or built-in cylinder type.But the rubber cracky of rubber chuck, application life is short.Built-in cylinder type chuck when changing slips, need to all just can be changed the slips operation after the dismounting with chuck, and required time is long, inefficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of good sealing effect is provided, and slips is changed convenient and the time spent weak point, a kind of oild chuck of chuck long service life.
The purpose of this utility model is achieved in that a kind of oild chuck, it is characterized in that it is comprised of a watt seat, chuck seat, screw, sealing ring, cover plate, two sealing rings, slips, elastic spring, pressing plate, three screws, wear ring, piston, spring, piston seats.
Described slip spider and pressing plate are connected by screw and consist of a rectangle slideway, and slips can be done rectilinear motion in slideway; Four plunger shaft are arranged in the slip spider, and piston is arranged in the slip spider and can does rectilinear motion in slip spider;
Described chuck seat 2 is connected with cover plate 5 by screw 3; Be provided with sealing ring 4 between chuck seat 2 and the cover plate 5; Be provided with sealing ring 6 between cover plate 5 and the piston seat 16; Be provided with sealing ring 13 and wear ring 12 between piston and the piston seat 16; Elastic spring is arranged in the inner wall groove of slips, when needs unclamp slips, relies on the elasticity of elastic spring that slips is strutted;
Screw 11 is used for connecting pressing plate (9) and piston seat (16), and some springs 15 arrange respectively between piston and the piston seat.
Described slip spider (1) and pressing plate (9) connect and compose slideway by screw II (10), and slips (7) can move in slideway.
Slideway of the present utility model can provide the slips mobile space, only need unload lower platen when changing slips and slips can be extracted out in slip spider, need not to take apart whole oild chucks.Adopt hydraulic jack to clamp slips, solved present open type oild chuck and adopted easily damaged, leakage of oil of rubber sleeve, the problem that causes chuck to lose efficacy.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 be Fig. 1 along A-A to sectional view.
Among the figure, 1, slip spider, 2, chuck seat, 3, screw, 4, sealing ring, 5, cover plate, 6, sealing ring, 7, slips, 8, elastic spring, 9, pressing plate, 10, screw, 11, screw, 12, wear ring, 13, sealing ring, 14, piston, 15, spring, 16, piston seat, 17, hydraulic fluid port, 18, hydraulic cavities.
The specific embodiment
Embodiment: Fig. 1, shown in Figure 2, it is comprised of present embodiment slip spider 1, chuck seat 2, screw 3, sealing ring 4, cover plate 5, sealing ring 6, slips 7, elastic spring 8, pressing plate 9, screw 10, screw 11, wear ring 12, sealing ring 13, piston 14, spring 15, piston seat 16.
Described slip spider 1 and pressing plate are connected by screw and consist of a rectangle slideway, and slips is arranged in the slideway can do rectilinear motion;
Four plunger shaft are arranged in the slip spider, and piston can be done rectilinear motion in slip spider;
Be provided with sealing ring 6 between cover plate 5 and the piston seat 16; Be provided with sealing ring 13 and wear ring 12 between piston and the piston seat 16; Screw 11 is used for connecting pressing plate 9 and piston seat 16.
Some springs 15 arrange respectively between piston and the piston seat.
The course of work of the utility model embodiment is as follows: hydraulic oil enters hydraulic cavities 18 by hydraulic fluid port 17 during clamping, hydraulic oil pushing piston 14, and piston 14 promotes slips 7 and clamps drilling rod.Lay down hydraulic oil when unclamping, spring 15 pushing pistons 14, elastic spring 8 promote slips 7 and unclamp drilling rod.
Unclamp screw 10 when changing slips, screw 11 unloads lower platen 9, pulls out slips 7, changes suitable slips with screw 10 clamping platens 9, usefulness screw 11 is connected with piston seat 16.
