Abstract
One kind is with sideways against power hydraulic cylinder, rear end of the cylinder block installs rear end cap, cylinder body front end internal clearance is coupled oscillating bearing lid, piston rod is equipped in cylinder body, piston is slidably mounted in cylinder body, and lower part insertion installation upper surface is the bottom fixed block on inclined-plane in piston hole, installs rotational pin on the inclined-plane of bottom fixed block, piston rod rear end and rotational pin clearance fit are installed, and piston rod front end is through oscillating bearing lid and wears the installation of oscillating bearing lid clearance fit.The utility model has the beneficial effects that structure designs advantages of simple, and it is small in size, do not increase oil cylinder dead weight, it is compact-sized, two oil cylinders are not needed laterally realizes side pushing effect；Saving personnel utilize and manufacturing cost in terms of, since oil cylinder is lateral backup, when hanged weight, is easy to be accurately positioned, make to adjust etc. work become more easily effectively.
Description
Technical field
The utility model relates to hydraulic cylinder technical fields.
Background technique
With the fast development of economic construction of China, market is growing for hydraulic cylinder product demand.Currently, large-scale
The high mechanized equipment such as crane, excavator, loading machine is equipped with the engineerings hydraulic cylinder such as lifting, push-and-pull, small-sized to hang
Central role is played during weight, loading etc..The oil cylinders such as straight line push-and-pull, corner, screw thread on hydraulic tool fixture also function to
Vital effect；The problem of lateral backup function of hydraulic cylinder is current puzzlement technical staff, standard hydraulic cylinder is unbearable
Lateral force, it is even more impossible to realize lateral backup function.Standard will use two oil cylinders and carry out function integration when designing, realization laterally pushes away
By effect, structure is complicated, and service performance is poor.
Utility model content
The above problem existing for lateral backup function is realized in order to solve hydraulic cylinder, and the utility model provides a kind of band
Have sideways against power hydraulic cylinder.
The utility model technical solution used for the above purpose is: one kind has sideways against power hydraulic cylinder,
Rear end of the cylinder block installs rear end cap, and cylinder body front end internal clearance is coupled oscillating bearing lid, piston rod is equipped in cylinder body, and piston is sliding
Dynamic to be installed in cylinder body, lower part insertion installation upper surface is the bottom fixed block on inclined-plane, the inclined-plane of bottom fixed block in piston hole
Upper installation rotational pin, piston rod rear end and rotational pin clearance fit are installed, and piston rod front end is through oscillating bearing lid and wears joint
The installation of bearing cap clearance fit.
The oscillating bearing lid clearance fit is sealed on cylinder body and by seal ring assembly.
The hydraulic cylinder piston rod is sealed with oscillating bearing lid clearance fit and by cylinder piston rod seal ring assembly.
The rotational pin is connect with fixed sole piece flute profile.
The utility model has the beneficial effects that structure designs advantages of simple, and it is small in size, do not increase oil cylinder dead weight, structure
It is compact, two oil cylinders are not needed laterally realizes side pushing effect；Saving personnel utilize and manufacturing cost aspect, since oil cylinder is lateral
Backup, be easy when hanged weight to be accurately positioned, make to adjust etc. work become more easily effectively.
Detailed description of the invention
Fig. 1 is that the utility model has sideways against power hydraulic cylinder main view sectional structure chart.
In figure: 1, rear end cap, 2, cylinder body, 3, piston, 4, bottom fixed block, 5, rotational pin, 6, piston rod, 7, oscillating bearing
Lid.
Specific embodiment
The utility model has sideways against power hydraulic cylinder structure as shown in Figure 1, including 2, pistons of a cylinder body
6, one, bar, 7, one, oscillating bearing lid, 3, one, the piston bottom fixed block 4 of rear end cap 1, one and a rotational pin 5, piston 3
Sliding is contained in cylinder body 2, and 7 clearance fit of oscillating bearing lid is sealed on cylinder body 2 and by seal ring assembly, hydraulic cylinder piston
It bar 6 and 7 clearance fit of oscillating bearing lid and is sealed by cylinder piston rod seal ring assembly, rear end cap 1 is threadedly connected to cylinder body 2
On, lower part insertion installation upper surface is the bottom fixed block 4 on inclined-plane in 3 hole of piston, installs rotation on the inclined-plane of bottom fixed block 4
Pin 5, piston rod 6 and 5 clearance fit of rotational pin, rotational pin 5 are linked with fixed 4 flute profile of sole piece.
In use, piston rod 6 push piston 3 slided in cylinder body, due in piston 3 the bottom of the slope fixed block and rotation
Lateral backup is realized in the effect of pin, and when hanged weight is easy to be accurately positioned, make to adjust etc. work become more easily effectively.
The utility model is described by embodiment, and those skilled in the art know, practical new not departing from this
In the case where the spirit and scope of type, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, at this
Under the introduction of utility model, it can modify to these features and embodiment to adapt to particular situation and material without taking off
Spirit and scope from the utility model.Therefore, the utility model is not limited to the particular embodiment disclosed, and is owned
The embodiment fallen within the scope of claims hereof belongs to the protection scope of the utility model.
