Description
Technical field
The utility model relates to mechanical part connection area, relates in particular to oil cylinder piston rod connecting device.
Background technique
Oil cylinder is power plant common in machinery, and cylinder piston rod is the power output position of oil cylinder.Common is fixedly connected with piston rod about being connected to directly of cylinder piston rod with the mechanical part that will drive.This Placement defines the moving direction of cylinder piston rod.When oil cylinder and the mechanical part that will drive, install while there is among a small circle deviation, the moving direction of cylinder piston rod also there will be deviation, and long-term work in this case can be caused the oil cylinder shortening in working life.When the driving force of oil cylinder is excessive, the reaction force of driving force directly acts on cylinder piston rod, causes the damage of cylinder piston rod.
Summary of the invention
Problem to be solved in the utility model is the transmission direction that the connection set of existing cylinder piston rod defines piston rod, can not correct the deviation among a small circle occurring in installation, has shortened the working life of oil cylinder.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: oil cylinder piston rod connecting device is provided.Described oil cylinder piston rod connecting device comprises connecting base.The mechanical part that described connecting base connection cylinder piston rod and oil cylinder will drive.
Described connecting base comprises fixed end and connecting end, and described fixed end is fixedly connected with described connecting end.Described fixed end has tapped hole.Described connecting end has the first hole.
Preferably, described fixed end has fastener hole, and the opening direction of described fastener hole and the axial direction of described tapped hole are perpendicular, and described fastener hole ends at the outer wall of described tapped hole.Described connecting base also comprises fastening piece, and described fastening piece and described fastener hole match.
Preferably, in described the first hole, be provided with bearing.
Preferably, described connecting base also comprises the axle matching with described bearing.Described axle is bolt or bearing pin.
Described axle, through described bearing, allows the rich described axle of described connecting base to rotate.Described bearing makes connecting base more flexible around the rotation of axle, and in addition, bearing also can reduce the wearing and tearing of rotating axle, increases the working life of axle.
Advantage and the good effect that the utlity model has are:
(1) the oil cylinder piston rod connecting device that uses the utility model to provide, cylinder piston rod is more fastening with being connected of connecting base.
(2) when oil cylinder and the mechanical part that will drive are installed while there is among a small circle deviation, this oil cylinder piston rod connecting device can, by the transmission direction that cylinder piston rod is corrected in rotation voluntarily among a small circle around axle, stop the damage of installation deviation to cylinder piston rod when oil cylinder is worked.
(3) when hydraulic oil cylinder driving power is excessive, the oil cylinder piston rod connecting device that the utility model provides can alleviate by the rotation around axle the reaction force of driving force, thereby prevent the damage of the reaction force of driving force to cylinder piston rod, extend the working life of cylinder piston rod.
(4) the utility model is simple in structure, and simple and fast is installed, easy to use.

Embodiment
In order better to understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is conducted further description.
Embodiment 1
As depicted in figs. 1 and 2, oil cylinder piston rod connecting device, comprises connecting base 1.Connecting base 1 comprises fixed end 11 and connecting end 12, and fixed end 11 and connecting end 12 are one-body molded, are fixedly connected with.In the present embodiment, oil cylinder piston rod connecting device connects cylinder piston rod 3 and ingot cover 2.Oil cylinder piston rod connecting device is fixedly connected with cylinder piston rod 3, is flexibly connected with ingot cover 2.
Fixed end 11 has the tapped hole 113 that the front end outside thread with cylinder piston rod 3 matches, and fixed end 11 is spirally connected by tapped hole 113 and cylinder piston rod 3.On fixed end 11, have the fastener hole 111 for further fixed oil cylinder piston rod 3.The opening direction of fastener hole 111 and cylinder piston rod 3 axial directions are perpendicular, and fastener hole 111 ends at the outer wall of tapped hole 113.Connecting base 1 also comprises the fastening piece 112 matching with fastener hole 111.Fastening piece 112, through fastener hole 111, ends at cylinder piston rod 3.Fixed end 11 is spirally connected with cylinder piston rod 3, but when the driving force of oil cylinder is excessive sometimes, is spirally connected that it is a little loosening to there will be, and makes the connection of cylinder piston rod 3 and connecting base 1 no longer so tight.Fastening piece 112 ends at the leading portion outside thread of cylinder piston rod 3, and fastening piece 112 destroys the screw thread of tapped hole 113, makes the connection of cylinder piston rod 3 and connecting base 1 more firm.
Connecting end 12 has in 121, the first holes 121, the first hole and is provided with bearing 122.Connecting base 1 also comprises the axle matching with bearing 122.The present embodiment axis is bolt 123, and axle can also be that other plays the part that is similar to rotating shaft effect, as bearing pin.There is the nut matching with it bolt 123 lower ends.In the present embodiment, connecting base 1 is flexibly connected with ingot cover 2, and ingot cover 2 has the groove matching with connecting end 12.On ingot cover 2, have the second hole 21 matching with the first hole 121.Bolt 123 is through the second hole 21 and the first hole 121, connecting end 12 and ingot cover 2 are flexibly connected, in the first hole 121, be provided with bearing 122, make connecting base 1 more convenient around the rotation of bolt 123, bearing 122 also can alleviate the damage of rotating bolt 123 and connecting end 12.
