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.Beneficial effects of the present invention: structure designs advantages of simple, small in size, does not increase oil cylinder dead weight, compact-sized, does not need two oil cylinders laterally and 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 present invention 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.
Summary of the invention
The above problem existing for lateral backup function is realized in order to solve hydraulic cylinder, and the present invention provides one kind to have side
To motive force hydraulic cylinder.
Present invention technical solution used for the above purpose is: one kind is with sideways against power hydraulic cylinder, cylinder body
Rear end cap is installed in rear end, and cylinder body front end internal clearance is coupled oscillating bearing lid, and piston rod, piston sliding peace are equipped in cylinder body
Loaded in cylinder body, lower part insertion installation upper surface is the bottom fixed block on inclined-plane in piston hole, is pacified on the inclined-plane of bottom fixed block
Rotational pin is filled, piston rod rear end and rotational pin clearance fit are installed, and piston rod front end is through oscillating bearing lid and wears oscillating bearing
The installation of lid 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.
Beneficial effects of the present invention: structure designs advantages of simple, small in size, does not increase oil cylinder dead weight, compact-sized,
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 the present invention with 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
It is of the invention with sideways against power hydraulic cylinder structure as shown in Figure 1, include 2, piston rods 6 of a cylinder body,
One 7, one, oscillating bearing lid, 3, one, piston rear end cap, 1, bottom fixed block 4 and a rotational pin 5, piston 3 slide
It is contained in cylinder body 2,7 clearance fit of oscillating bearing lid is sealed on cylinder body 2 and by seal ring assembly, hydraulic cylinder piston rod 6
With 7 clearance fit of oscillating bearing lid and sealed by cylinder piston rod seal ring assembly, rear end cap 1 is threadedly connected on cylinder body 2,
Lower part insertion installation upper surface is the bottom fixed block 4 on inclined-plane in 3 hole of piston, installs rotational pin on the inclined-plane of bottom fixed block 4
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 present invention is described by embodiment, and those skilled in the art know, is not departing from spirit of the invention
In the case where range, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in religion of the invention
It leads down, can modify to these features and embodiment to adapt to particular situation and material without departing from essence of the invention
Mind and range.Therefore, the present invention is not limited to the particular embodiment disclosed, fallen with claims hereof
Embodiment in range belongs to protection scope of the present invention.
