Description
Technical field
The utility model relates to a kind of oil cylinder or cylinder as coupler, is a kind of drive disk assembly can be used on the equipment such as metallurgical machinery, construction machinery and equipment, lathe.
Background technology
At present, the harmomegathus mode that unreels head of the rolling head of the winder on strip processing line, unreeling machine has two kinds: a kind of is the automatic harmomegathus of hydraulic pressure, and another kind is artificial harmomegathus.
Adopt the automatic harmomegathus mode of hydraulic pressure, reductor and rolling head or unreel head and be connected, the reductor of the reductor criteria of right and wrong, the shaft of substandand reductor adopts quill shaft, the harmomegathus that realizes rolling head or unreel head by common oil cylinder and axial-rotation joint (can buy on market) are installed at substandand reductor shaft afterbody.Because need to make substandand reductor, its price, fabrication cycle is long, quality is unstable, and commonality is not strong.
Adopt artificial harmomegathus mode, reductor is with rolling head or unreel and be connected, what install is the reductor of standard, the reductor of standard is because shaft is solid axle, common oil cylinder and axial-rotation joint cannot be installed, need employing manpower is pulled rolling head or is unreeled the screw mandrel of a leading section, by screw thread type of drive, realize rolling head and the harmomegathus that unreels head, due to rolling head with after unreeling head work, the predetermincd tension of screw thread is large, so people's labour intensity is large, and adopts artificial harmomegathus mode, speed is slow, is difficult for adjusting in work.
In addition, current many construction machinery and equipments, machine equipment needs long distance work (active force part and execution head distance, as dredge engineering equipment, deep-hole boring machine etc.), carry out head and not only need spinning movement, and there are feed and a withdrawing, gripping and unclamping, the additional move such as harmomegathus, the method adopting is now: quill shaft connecting device active force part and execution head, end face (near active force part) at quill shaft arranges common oil cylinder and axial swivel coupling, by the little axle in common oil cylinder pushing quill shaft (connecting common oil cylinder and head), realize additional move.This mode has limited operation distance: 1, if the restriction of quill shaft actual condition is less, little axle is also smaller, is unfavorable for that little axle (depression bar) is stable, and little axle can not be oversize; 2, bearing is set in quill shaft and supports little axle, quill shaft neck bearing installation position needs very high concentricity, processing difficulties, otherwise the spinning movement of execution head will exert an influence to additional move.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of oil cylinder that can be used as coupler, not only possesses the function of known oil cylinder, can use transmitting torque as coupler simultaneously.
The utility model is as the oil cylinder of coupler, this oil cylinder comprises cylinder body 7, cylinder body 7 is provided with oil inlet and outlet 101, this oil cylinder also comprises radial rotary connection and is connected in the flange 1 at described cylinder body 7 two ends, described radial rotary connection comprises fixed cover 6 and is arranged at the bearing 4 at fixed cover 6 two ends, fixed cover 6 is provided with into oil out port 107, along fixed cover 6 inwalls, is provided with turnover oil groove 106, described turnover oil groove 106 and oil inlet and outlet 101 with enter oil out port 107 and be communicated with.
Described cylinder body 7 is provided with keyway 103 with flange 1 end face.Flange 1 end face has seam.
Described radial rotary connection is also provided with back-up ring 3 and seal ring 5.
Described flange 1 is fixing with cylinder body 7 by holding screw 2.
Described fixed cover 6 is provided with the installation position 104 of bearing 4, the mounting groove 105 of seal ring 5.
This oil cylinder also comprises circular cone rod bearing 11 and the bearing seat 10 being arranged between flange 1 and radial rotary connection.
The utility model also provides a kind of cylinder that can be used as coupler, not only possesses the function of known cylinder, can use transmitting torque as coupler simultaneously.
The beneficial effects of the utility model are:
(1) cylinder body can be used as coupler use, is connected to standard reductor and rolling head or unreels 360 ° of rotation transmitting torques between head;
(2) setting of radial rotary connection, makes oil cylinder (cylinder) possess the function of known oil cylinder (cylinder), realizes rolling head or unreels the automatic harmomegathus mode of hydraulic pressure of head;
(3) cylinder body is used as coupler, is connected to quill shaft and carries out transmitting torque between head, realizes the additional move of carrying out head, has evaded the deficiency that little axle is set in quill shaft, has avoided the restriction to operation distance.
Accompanying drawing explanation
Fig. 1 is the shaft side figure of a specific embodiment of the utility model.
Fig. 2 is the axial section constructional drawing of Fig. 1.
Fig. 3 is the axial section of fixed cover 6.
Wherein, 1 flange, 2 holding screw 3 back-up rings, 4 bearings, 5 seal rings, 6 fixed covers, 7 cylinder bodies, 8 piston rods, 9 pistons, 10 bearing seats, 11 tapered roller bearings, 101 turnover oilholes, 102 inner chambers, 103 keyways, 104 bearing 4 installation positions, 105 seal ring 5 mounting grooves, 106 turnover oil grooves, 107 enter oil out port.
The specific embodiment
Cylinder of the present utility model is identical with cylinder structure, and the oil cylinder of take below describes as example.
As shown in Figure 1 and 2, oil cylinder of the present utility model comprises: cylinder body 7, piston rod 8, piston 9, flange 1, and radial rotary connection.On cylinder body 7, there is oil inlet and outlet 101.Two flanges 1 are connected in cylinder body 7 two ends, can be fixing with cylinder body 7 by holding screw 2.
Cylinder body 7 turnover oilhole 101 places, two ends arrange respectively a radial rotary connection, and described radial rotary connection comprises fixed cover 6 and is arranged at the bearing 4 at fixed cover 6 two ends.In reality, also can be provided with back-up ring 3 in a side, on bearing 4 sides, seal ring 5 is set, can be rotary seal ring.
Fixed cover 6 is provided with into oil out port 107 and the turnover oil groove 106 that arranges along inwall.Enter oil out port 107 connected pipes.Pass in and out oil groove 106 with oil inlet and outlet 101 and enter oil out port 107 and be communicated with.As shown in Figure 3, fixed cover 6 is provided with the installation position 104 of bearing 4, the mounting groove 105 of seal ring 5.
Can, by feather key being set on the parts that connect at piston rod 8, flange 1, realize between cylinder body 7 and piston rod 8, piston 9 without relatively rotating.
Cylinder block 7 forms coupler with flange 1.Cylinder body 7 processes keyway 103 with flange 1 end face, and flange 1 end face is processed with seam.Using cylinder body 7, flange 1 connection standard reductor and rolling head or unreel head and use 360 ° of rotation transmitting torques as coupler.During work, cylinder body 7, flange 1, piston rod 7 can synchronously rotate, and fixed cover 6 does not rotate, thereby the oil pipe of avoiding being connected on fixed cover 6 is wound around.Owing to being provided with radial rotary connection, no matter whether cylinder body 7 rotates, and pressure oil can, by entering oil out port 107 and turnover oil groove 106 turnover cylinder body 7 inner chambers 102 smoothly, promote piston rod 8, piston 9 actions, thereby the function with known oil cylinder, realize rolling head or unreel head harmomegathus.
While moving under piston rod 8, the effect of piston 9 at fluid pressure, when if the equipment component that flange 1 two ends connect can not bear the axial force of this action generation, can be by setting up bearing seat 10 between flange 1 and radial rotary connection, tapered roller bearing 11 bears axial force.
