Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, relates in particular to the oil hydraulic cylinder of a kind of tape guide and detection.
Background technique
The utility model relates to casting equipment industry, is process materials with clay-bonded sand, adopts the functional part of high pressure molding.At present, this functional part both domestic and external has several patterns, mainly is assembled on the integrated package with part.A kind of is that integrated package is processed by cylinder barrel, and with piston-rod assembly, in the integrated package of directly packing into, the upper and lower hydraulic fluid port of oil cylinder all on integrated package, is concentrated for pressure oil a plurality of oil cylinders; Another kind is that integrated package is processed into the logical oil body in bar chamber (near rod end), and the plug chamber connects with oil pipe, uses double sealing between cylinder barrel and integrated package, and is similar with known pull bar cylinder.The former processing charges height, manufacturing cycle are long, and its rod end is installed square ram, has to detect and guiding; The latter has detection and does not have guiding, rod end is installed spherical head, because pull bar is subjected to frequent tensile buckling, there is the microcosmic play in seal ring, produces wearing and tearing, the loss that causes vital part one integrated package to repair between seal ring and integrated package, in addition, when leakage of oil occurring, not only servicing ease is poor, and easily causes hydraulic system pollution.
Summary of the invention
The utility model provides a kind of novel hydraulic cylinder at the deficiencies in the prior art, and it not only reduces manufacture cost effectively, and has improved the availability and the maintainalbility of this functional part widely.
This programme is realized by following technical measures: the oil hydraulic cylinder of a kind of tape guide and detection, it comprises cylinder assembly and the piston-rod assembly that is arranged in the cylinder assembly, it is characterized in that described cylinder assembly comprises integrally welded back cylinder cover and cylinder barrel, front end at cylinder barrel is provided with tubular cylinder head and gland, gland is fixed together cylinder head and integrated package by bolt, and described back cylinder cover is provided with detecting switch and plug chamber hydraulic fluid port; Piston area center at piston rod is provided with pilot hole, built-in piston guide rod in the pilot hole, and piston guide rod one end is fixedly set on the back cylinder cover; Plug head at piston rod is provided with the spline cover, and the spline cover is sleeved on the piston guide rod; The cylinder head sidewall is provided with bar chamber hydraulic fluid port, next-door neighbour's cylinder head position suit oil duct integrated package on cylinder barrel, and bar chamber hydraulic fluid port is communicated with the oil duct integrated package;
The piston rod guide sleeve assembly of band Sealing is set in cylinder head, and piston rod guide sleeve assembly is sleeved on the piston rod, and piston rod guide sleeve assembly has gland to be pressed on the cylinder head.
Be threaded between oil duct integrated package and the cylinder barrel.Be provided with sealing plate between oil duct integrated package and the cylinder head.Piston guide rod is connected with back cylinder cover in the cylinder assembly by pin.
The utility model beneficial effect is: adopt single cylinder integral solder structural type, simple in structure, cost is low, and bar chamber hydraulic fluid port is arranged on the cylinder head sidewall, and is connected with the oil duct integrated package.Adopt the sealing plate of easy convenient for maintaining between bar chamber hydraulic fluid port and oil duct integrated package, under the situation of not exclusively pulling down oil cylinder, replaceable bar chamber hydraulic fluid port Sealing.Not only convenient for maintaining, and hydraulic fluid port down, the contaminated liquid pressing system simultaneously, does not reach the purpose of integrated package easy processing yet.Piston rod is scalable, but does not rotate.The piston guide rod that connects spline at welded structure cylinder barrel top, dress spline cover in the piston, the guide function of realization piston rod.At welded structure cylinder barrel top dress detecting switch, detect the piston-retraction position.Manufacturing cycle is short, uses reliable, easy to maintenance.
