The semicircle aperture at half earrings position of 11 other end of bar is abutted with hinged shaft 8, and first connecting rod 4, second connecting rod 11 and hinged shaft 8 connect
The both ends of the surface of half earrings of touching have the first convex shoulder 15 and the second convex shoulder 17 of semi-annular shape, the position Wai Yuan of the first convex shoulder 15 respectively
It being slidably matched with the inner hole of the first retaining ring 7, the position Wai Yuan of the second convex shoulder 17 and the inner hole of the second retaining ring 16 are slidably matched,
The thickness of first retaining ring 7 is equal with the height of the first convex shoulder 15, the height of the thickness of the second retaining ring 16 and the second convex shoulder 17
It is equal；One end that crank 6 and hinged shaft 8 cooperate is that ears are cyclic annular, and crank 6 is with the both ends of the surface on the inside of ears looped end respectively with the
One convex shoulder 15, the second convex shoulder 17 both ends of the surface be slidably matched, the other end that crank 6 is not connect with hinged shaft 8 pass through key 9 and drive shaft
5 cooperations.The semicircle aperture at half earrings position of first connecting rod 4, second connecting rod 11 and hinged shaft 8 contact pressure-bearing in the present invention, lead to
Cross the first retaining ring 7, the second retaining ring 16 makes first connecting rod 4, second connecting rod 11 and crank 6 and hinged shaft 8 remains hinge-like
State.
As shown in Figure 3, Figure 4, first connecting rod 4, second connecting rod 11 initial stage blank be a disjunctor connecting rod shape casting, should
Casting both ends are the earrings connecting with first piston axis 3, second piston axis 12, and central location is the earrings cooperated with hinged shaft 8.
As shown in figure 5, central location round earrings after processing is completed, with cutting tool in the position of disjunctor connecting rod symmetrical center line d
Set the top of central earrings is cut off to be formed two parallel and symmetrical first sides 18, by central earrings axial line and with
Central earrings lower part is cut into two symmetrical second sides 19 at the position that disjunctor connecting rod symmetrical center line d makes an angle alpha,
A piece disjunctor connecting rod Mechanical processing of casting is divided into two shapes and size is identical, one end is in the first connecting rod 4 of half earrings shape and the
Two connecting rods 11.
Specific work process of the invention is as follows:
Shown in solid line figure as shown in figure 1, crank 6 when with the first oil cylinder 1, the second 14 symmetrical middle position of oil cylinder,
The axis of symmetry b of crank 6 is overlapped with executing agency symmetrical center line a, and axis of symmetry b and the first oil cylinder 1, the second oil cylinder 14
Axial line it is vertical, the folder of first connecting rod 4, the axis of symmetry c of second connecting rod 11 and the first oil cylinder 1,14 axial line of the second oil cylinder
Angle is maximum (angle is 10 ° ± 3 °), there are 2 α of angle between first connecting rod 4, each first side 18 of second connecting rod 11, each the
There are gaps between two side faces 19.
Shown in double dot dash line figure as shown in figure 1, crank 6 is when 90 ° of angle strokes play (end) point position, axis of symmetry b
It is in 45 ° of angles, the first connecting rod 4 of the location point, the axis of symmetry c of second connecting rod 11 and the with executing agency symmetrical center line a
One oil cylinder 1,14 axial line of the second oil cylinder angle be 0 ° or so, deposited between first connecting rod 4, each first side 18 of second connecting rod 11
There are 2 α of angle between gap, each second side 19, first connecting rod 4, second connecting rod 11 half earrings end in 90 ° of angle stroke works
It will not be interfered with each other during work.
As shown in Figure 1, the drive shaft 5 of executing agency is connect with the main shaft of angular travel valve, when valve needs to make positive turn
When dynamic, the high pressure oil from external hydraulic power supply enters the first oil cylinder 1 from oil connection A and acts on first piston 2, by the
One piston shaft 3 drives the semicircle osseotomy site at half earrings end of first connecting rod 4 to push hinged shaft 8, and passes through crank 6, key 9, drive
Moving axis 5 is rotated forward with movable valve.Meanwhile hinged shaft 8 is contacted with the semicircle osseotomy site at half earrings end of second connecting rod 11,
It pushes second connecting rod 11, second piston axis 12 and second piston 13 is driven to move right, pass through the oil liquid in the second oil cylinder 14
The oil pipe of pipe fitting B returns to the low pressure oil pocket of external hydraulic power supply.
As shown in Figure 1, when valve needs to make counter motion, the high pressure oil from external hydraulic power supply is from oil connection
B enters the second oil cylinder 14, acts on second piston 13, and the semicircle at half earrings end of second connecting rod 11 is driven by second piston axis 12
Shape osseotomy site pushes hinged shaft 8, and makees counter motion with movable valve by crank 6, key 9, drive shaft 5.Hinged shaft 8 and first simultaneously
The semicircle opening contacts at half earrings end of connecting rod 4 push first connecting rod 4, first piston axis 3 and drive first piston 2 to the left
It is mobile, so that the oil liquid in the first oil cylinder 1 is returned to the low pressure oil pocket of external hydraulic power supply from the oil pipe of pipe fitting A.Knot of the present invention
Structure is simple, easy to use, low in cost, and first connecting rod and second connecting rod using a disjunctor connecting rod Mechanical processing of casting and are divided into two
Root one end is the connecting rod of half earrings shape, so that the connecting portion small volume of first connecting rod, second connecting rod and crank and hinged shaft,
Since the axis of symmetry of first connecting rod and second connecting rod and the angle of oil cylinder axial line are small, oil cylinder piston in the stroke course of work of angle
Action of hydraulic force it is smaller in the radial component of cylinder body, reduce related components structure and in terms of design want
It asks.
Above description is explanation of the invention, is not intended to limit the invention, and limited range of the present invention is referring to right
It is required that the present invention can make any type of modification without prejudice to basic structure of the invention.
