Abstract
The utility model provides a hydraulic oil cylinder with a novel guide sleeve structure, which belongs to the technical field of hydraulic oil cylinder. A threaded cover is arranged on a guide ring to substitute for a bolt group and a cover, so that the problem in preventing looseness of the bolt group consisting of a plurality of bolts is converted to the problem in preventing looseness of a large threaded part; and a set screw is pressed at the joint of the threaded cover and the guide sleeve to prevent the looseness of the threaded cover. The threaded cover is made of copper alloy or copper and is provided with a guide ring to ensure the guide performance and the lateral support capability of the hydraulic cylinder, so that the hydraulic cylinder can effectively resist the lateral load. The production practice proves that the hydraulic oil cylinder has the advantages of high assembly processability, good effect in preventing looseness, low assembly and processing difficulty, improved production efficiency, long service life, and suits occasions with severe conditions, such as frequent operation, large vibration and the presence of lateral force.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, particularly a kind of hydraulic jack with novel guide sleeve structure.
Background technique
The existing hydraulic jack of V-arrangement composite rim that adopts all is provided with an adjustment ring on V-arrangement composite rim side, will adjust ring with gland and bolt group again and compress.But bolt is easily loosening under the situation frequent in work, that vibrations are bigger, produces potential safety hazard.Though can take to strengthen pretightening force, screw thread gluing, add locking cap even wear measure such as steel wire in bolt head punching locking, these methods are not that too complexity is exactly that anti-loosing effect is not good.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of hydraulic jack with novel guide sleeve structure, and the difficulty that can solve the locking thread problem and reduce processing and assembled has improved manufacturing efficiency.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of hydraulic jack with novel guide sleeve structure, comprise cylinder body, piston rod is installed in the cylinder body, piston is installed on the piston rod, between piston rod and the cylinder body guide sleeve is installed, be provided with O shape circle and O shape circle back-up ring between guide sleeve and the cylinder body, be provided with the V-arrangement composite rim between guide sleeve and the piston rod and adjust ring, be provided with union (screwed)bonnet (UB in the guide sleeve, union (screwed)bonnet (UB is provided with Cock screw, and guide sleeve is installed on the cylinder body by card key, baffle ring and back-up ring.
Described union (screwed)bonnet (UB is connected with guide sleeve by screw thread.
Described union (screwed)bonnet (UB is provided with 2～4 tapped hole is installed.
Described union (screwed)bonnet (UB material is a Cuprum alloy system, is provided with dust ring in it.
Described union (screwed)bonnet (UB material is a steel, is provided with dust ring and guide ring in it.
A kind of hydraulic jack that the utility model provides with novel guide sleeve structure, by union (screwed)bonnet (UB being set at guide ring, replace bolt group and gland with union (screwed)bonnet (UB, the locking problem of the bolt group that a plurality of bolts are constituted converts the locking problem of a major thread part to like this, by squeezing into Cock screw, prevent the loosening of union (screwed)bonnet (UB then at union (screwed)bonnet (UB and guide sleeve joint.Union (screwed)bonnet (UB is that Cuprum alloy is made or steel still is furnished with guide ring simultaneously, has so just guaranteed the steering capability and the lateral support ability of oil hydraulic cylinder, can resist lateral load effectively.Prove that through production practices this structure assembly process process is strong, anti-loosing effect is good, and the difficulty that has reduced processing and assembled, improved manufacturing efficiency, long service life, the work that is highly suitable for is frequent, vibrations are big, the comparatively abominable occasion of operating mode such as lateral force is arranged.
Description of drawings
Fig. 1 is the oil cylinder cross-sectional view based on the employing V-arrangement composite rim of prior art:
Fig. 2 is the cross-sectional view that adopts the Cuprum alloy union (screwed)bonnet (UB in the utility model:

Embodiment
In Fig. 1, be provided with V-arrangement composite rim 9 between guide sleeve 12 and the piston rod 1 and adjust ring 8, install by gland 6, packing ring 5 and a plurality of bolt 4 and locking cap 3, when general assembly, regulate pretty troublesomely, and a plurality of bolt 4 is locking also unreliable.
In Fig. 2 and Fig. 3, a kind of hydraulic jack with novel guide sleeve structure, piston rod 1 is installed in the cylinder body 14, piston 15 is installed on the piston rod 1, between piston rod 1 and the cylinder body 14 guide sleeve 12 is installed, be provided with O shape circle 10 and O shape circle back-up ring 11 between guide sleeve 12 and the cylinder body 14, be provided with V-arrangement composite rim 9 between guide sleeve 12 and the piston rod 1 and adjust ring 8, be provided with union (screwed)bonnet (UB 19 in the guide sleeve 12, union (screwed)bonnet (UB 19 is connected with guide sleeve 12 by screw thread, union (screwed)bonnet (UB 19 is provided with Cock screw 16, and guide sleeve 12 is by card key 7, baffle ring 18 and back-up ring 17 are installed on the cylinder body 14.Union (screwed)bonnet (UB 19 is provided with 2～4 tapped hole is installed.
After guide sleeve 12 at first installs guide ring 13, O shape circle 10, O shape circle back-up ring 11, V-arrangement composite rim 9 and adjusts ring 8 during assembling, connect with union (screwed)bonnet (UB 19 by internal thread again, integral body installs on the piston rod 1 then, the piston 15 that then will install Sealing installs on the piston rod 1, again the piston rod 1 that above-mentioned part the is housed cylinder body 14 of packing into, assembling card key 7, baffle ring 18, back-up ring 17 subsequently.According to the situation of delivery test, adjust the tightness that union (screwed)bonnet (UB 19 changes V-arrangement composite rim 9 at last, squeeze into Cock screw 16 again, finish final products.
The material of union (screwed)bonnet (UB 19 can be Cuprum alloy and steel, when union (screwed)bonnet (UB 19 materials are Cuprum alloy, is provided with dust ring 2 in it.When union (screwed)bonnet (UB 19 materials are steel, be provided with dust ring 2 and guide ring 20 in it.Can guarantee steering capability and lateral support ability like this.
The utility model has at first been simplified assembling: need tighten a plurality of bolt parts originally when general assembly, and tighten a thread part in the time of only need adorning in portion now and get final product; Secondly, the adjustment of V-arrangement composite rim is also more easy: need regulate a plurality of bolt parts repeatedly originally when adjusting, and only need to regulate a union (screwed)bonnet (UB now; Last original the locking of a plurality of bolt parts that need to consider only need prevent the loosening of a part union (screwed)bonnet (UB 9 by a Cock screw now, make product reliability improve, and anti-loosing effect is also better.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
