Description
Technical field
The utility model relates to a kind of oil cylinder, especially a kind of swinging, telescopic oil cylinder.
Background technique
At present, the effect of oil hydraulic cylinder in hydraulic system changes hydraulic energy into mechanical energy, makes machinery realize to-and-fro motion or oscillating motion.
By hydraulic jack transmitting torque and pivot angle, be that the fluid input with energy is converted into one of method of moment of torsion and pivot angle output, what this kind of swing hydraulic pressure oil cylinder was conventional has two kinds of structural types, that is: gear rack oscillating oil cylinder and blade oscillating oil cylinder.
Gear rack type swing oil cylinder composition comprises: the compositions such as linear oil cylinder, gear, tooth bar, gear rack type swing oil cylinder promotes tooth bar to-and-fro motion by linear oil cylinder, and rack and pinion is meshed thus reaches the output object straight reciprocating motion of oil cylinder being converted into the oscillating motion of gear.
The blade radial of blade oscillating oil cylinder is arranged, on hydraulic oil effect and blade, finally realizes the rotation of live axle.
Current oscillating oil cylinder all can only provide the moment of torsion of a kind of oil cylinder oscillating function, transmission, but can not both swing, again the function of straight line motion.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of can to swing and can the swinging, telescopic oil cylinder of straight line motion.
The utility model solves the swinging, telescopic oil cylinder that its technical problem adopts, comprise oscillating oil cylinder and two-way cylinder, oscillating oil cylinder comprises oscillating oil cylinder cylinder body and swing axis, described swing axis is provided with mounting hole vertically, the axle of described two-way cylinder to be arranged in the mounting hole of swing axis and can axial motion, and the two-way axle of described two-way cylinder coordinates for rotating transmission with between swing axis.
Further, described mounting hole is square hole, and the sectional shape of a section that the two-way axle of described two-way cylinder coordinates with mounting hole and mounting hole match.
Further, the sectional shape of described square hole is square.
Further, described oscillating oil cylinder is blade type oscillating oil cylinder.
The beneficial effects of the utility model are: coordinated by the connection of two-way cylinder and oscillating oil cylinder, can realize oscillating function, also can realize straight line motion function, can realize effect that is in place and clamping like this in machining frock.Be connected with square shaft by square hole between oscillating oil cylinder and two-way cylinder, this connection can be moved to axial and can not relatively rotate, thus oscillating oil cylinder and two-way cylinder are combined, and this simple and reliable for structure, cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A line sectional view of Fig. 1;
Component, position and numbering in figure: oscillating oil cylinder 1, two-way cylinder 2, swing axis 11, oscillating oil cylinder cylinder body 12, mounting hole 13, two-way axle 21.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises oscillating oil cylinder 1 and two-way cylinder 2, oscillating oil cylinder 1 comprises oscillating oil cylinder cylinder body 12 and swing axis 11, described swing axis 11 is provided with mounting hole 13 vertically, the axle of described two-way cylinder 2 to be arranged in the mounting hole 13 of swing axis 11 and can axial motion, and the two-way axle 21 of described two-way cylinder 2 coordinates for rotating transmission with between swing axis 11.Oscillating oil cylinder 1 and the axle both two-way cylinder 2 only transmission rotate and not transmission axial motion, this avoid the interference of two-way cylinder 2 pairs of oscillating oil cylinders 1.In the use of reality, when needs oscillating motion, only open oscillating oil cylinder 1; When needs to-and-fro motion, only open two-way cylinder 2; When to need oscillating motion and to-and-fro motion simultaneously, open oscillating oil cylinder 1 and two-way cylinder 2 simultaneously.The utility model makes oscillating oil cylinder 1 and two-way cylinder 2, and organically combination together, can straight line motion, can swing again, meet different user demands.
Concrete, as shown in Figure 2, described mounting hole 13 is square hole, and the sectional shape of a section that the two-way axle 21 of described two-way cylinder 2 coordinates with mounting hole 13 and mounting hole 13 match.The sectional shape of described square hole is generally square.The connection part of two-way axle 21 penetrates in mounting hole 13, and it can opposing oscillatory axle 11 straight line motion, but can not rotate relative to swing axis 11.Such structure is comparatively simple, and cost of production is low.
Two-way cylinder 2 is made up of two-way cylinder cylinder body, two-way axle 21, A hydraulic fluid port, B hydraulic fluid port, left and right end socket, seal ring and mounting screw.Described two-way cylinder cylinder body is provided with A hydraulic fluid port and B hydraulic fluid port; Left and right end socket is fixedly connected by mounting screw 1 and two-way cylinder cylinder body, and connection place is provided with at seal ring; Seal ring is provided with in left and right end socket; Seal ring 7 is equipped with in the piston outer ring of two-way axle 21, is assemblied in two-way cylinder cylinder body cylinder body; Hydraulic oil enters from A hydraulic fluid port, B hydraulic fluid port goes out, and two-way axle 21 moves right, otherwise two-way axle 21 is moved to the left.
