Yet existing oil hydraulic cylinder generally can not be measured the movement travel of piston rod, and the movement travel of piston rod is fixed, and flexibility is relatively poor.
Summary of the invention
The technical problem that the present invention mainly solves provide a kind of simple in structure, flexibility good, Installation and Debugging are convenient, can intuitively read the displacement amount of piston rod and the novel hydraulic oil cylinder of working position effectively.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of novel hydraulic oil cylinder is provided, comprises casing; Be provided with the hydraulic jack cylinder body in the said casing, be provided with piston and piston rod in the said cylinder body, the cylinder body two ends are connected with cylinder head and cylinder tail respectively; Said cylinder head one end is connected with and hangs head, and said cylinder tail is fixed with displacement transducer, and said displacement transducer is connected with piston; Said piston rod one end is fixed with slide bar, is provided with Sealing between said slide bar and the casing, and the slide bar end is fixed with slip ring; Said cylinder body one side rigid rod bar, said slip ring and scale bar are slidingly connected.
In preferred embodiment of the present invention, said Sealing is fixedly connected with casing through screw.
In preferred embodiment of the present invention, said slide bar is fixedly connected with piston rod through connecting rod.
In preferred embodiment of the present invention, said scale bar two ends are connected with cylinder head and cylinder tail respectively through fixed block.
In preferred embodiment of the present invention, said piston is provided with magnet ring, and said displacement transducer is electrically connected with magnet ring.
In preferred embodiment of the present invention, said slide bar is the hollow Stainless Steel Tube.
The invention has the beneficial effects as follows:
1, this novel hydraulic oil cylinder can accurately be measured the displacement amount of piston rod, and the signal that records is sent to control gear owing to be fixed with displacement transducer at cylinder tail one end;
2, because piston rod one end is fixed with slide bar, slip ring and scale bar, and in the Installation and Debugging stage, displacement transducer can't directly be read numerical value, this moment is reading numerical values on scale bar directly, has simplified installation and debugging work;
3, owing to be provided with Sealing between slide bar and the casing, under the situation of work under bad environment, Sealing can prevent that pollutant is along with slide bar gets in the casing together;
4, this novel hydraulic cylinder structure is simple, flexibility good, Installation and Debugging are convenient, has popularizing value.
Description of drawings
Fig. 1 is the perspective view of novel hydraulic oil cylinder one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, displacement transducer, 2, the cylinder tail, 3, piston, 4, slip ring, 5, cylinder body, 6, piston rod, 7, slide bar, 8, scale bar, 9, cylinder head, 10, Sealing, 11, casing, 12, connecting rod, 13, hang head, 14, fixed block.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of novel hydraulic oil cylinder comprises casing 11, is provided with hydraulic jack cylinder body 5 in the said casing 11; Be provided with piston 3 and piston rod 6 in the said cylinder body 5, cylinder body 5 two ends are connected with cylinder head 9 and cylinder tail 2 respectively, and said cylinder head 9 one ends are connected with and hang 13; Said cylinder tail 2 is fixed with displacement transducer 1, and said displacement transducer 1 is connected with piston 3, and said piston rod 6 one ends are fixed with slide bar 7; Be provided with Sealing 10 between said slide bar 7 and the casing 11; Slide bar 7 ends are fixed with slip ring 4, said cylinder body 5 one side rigid rod bars 8, and said slip ring 4 is slidingly connected with scale bar 8.
Said Sealing 10 is fixedly connected with casing 11 through screw; Because some is exposed at slide bar 7 outside the casing 11; When piston rod 6 was made the front and back ahead running, ahead runnings before and after slide bar 7 is done with piston rod 6 can be brought pollutant in the casing 11 into; To hydraulic oil pollution, can prevent effectively that through sealing part 10 this phenomenon from taking place.
Said slide bar 7 is fixedly connected with piston rod 6 through connecting rod 12, connect more firm, convenient disassembly.
Said scale bar 8 two ends are connected with cylinder head 9 and cylinder tail 2 respectively through fixed block 14, the slip ring 4 corresponding settings on scale bar 8 and the slide bar 7.
Said piston 3 is provided with magnet ring, and said displacement transducer 1 is electrically connected with magnet ring, and displacement transducer 1 is measured the displacement amount of piston rod 6 through the magnet ring on the piston 3.
Said slide bar 7 is the hollow Stainless Steel Tube, and processing is simple, long service life, and cost is lower,
Add man-hour; Ahead running before and after piston rod 6 is done, displacement transducer 1 comes the accurately displacement amount of measurement piston rod 6 through the magnet ring that induction is fixed on the piston 3, and measured signal is sent to control gear; Simultaneously; Piston rod 6 drives slide bars 7 and seesaws, and the Sealing 10 between slide bar 7 and the casing 11 can prevent that slide bar 7 from bringing casing 11 pollutants outward in the casing 11 into, owing to slide bar 7 ends are fixed with slip ring 4; Slip ring 4 is slidingly connected with scale bar 8, and the distance of on scale bar 8, sliding through slip ring 4 also can be read the displacement amount of current piston rod 6 intuitively.
