Abstract
A buffer test adjusting structure of a hydraulic oil cylinder includes a piston rod, a cylinder head, a cylinder body, a buffer jacket, a piston, a sealing element and an auxiliary which are mutually matched, wherein a buffer test adjusting structure communicating internal and external oil circuits of the cylinder is arranged on the cylinder head or the cylinder body and adopts a technical scheme that an adjusting hole communicating the internal and the external oil circuits of the cylinder is formed on the cylinder head or the cylinder body; a stop valve is arranged in the adjusting hole; a spring is arranged in the stop valve; a spring seat is covered above the spring; a plug screw is arranged outside the cylinder body or the cylinder head; the lower end of the plug screw is propped against the spring seat; and an O-shaped ring is sealed between the plug screw and the cylinder head or the cylinder body. A buffer adjusting mechanism is arranged in the corresponding positions of the cylinder head and the cylinder body, so as to facilitate adjusting buffer gap and the need of dismounting the oil cylinder to replace parts is avoided. The buffer adjusting mechanism including the stop valve, the spring, the spring seat, the O-shaped ring and the plug screw facilitates directly adjusting outside the oil cylinder body for an operator.
Description
Technical field:
The utility model belongs to technical field of hydraulic oil cylinder, relates to a kind of design that cushions regulating mechanism, and is especially relevant with a kind of hydraulic jack buffering test adjustment structure in the test phase use.
Background technique:
At present, in construction machinery product, because the continuous upgrading of product is more and more higher to the requirement of hydraulic system.For the excavator product, because the needs of job specification, its operation mechanism will steadily not impact, and this just requires the hydraulic jack in the operation mechanism that good cushioning effect will be arranged.The cushioning effect of excavator oil cylinder all is by drawing through test analysis behind the installation complete machine.Design the early stage can not calculate the buffer gap very accurately, and with a kind of excavator of tonnage type, and what different manufacturers produced also can be because of being not quite similar of product, and cushioning effect also is different.This just requires the excavator oil cylinder to need to adjust buffer parameter according to Measurement results after the installation test.
What adopt mostly at present in the prior art, all is that the dimensional parameters of taking oil cylinder replacing cylinder cap, cushion collar, cylinder bottom cushion hole etc. apart is adjusted cushioning effect.It is roughly in proper order takes cylinder cap-take apart piston-exchange buffering cover, cylinder cap-assembling piston-assembling cylinder cap apart.Carry out the test analysis cushioning effect after assembling again, effect does not reach requirement and just continues to repeat more to change jobs.This kind mode increases the process component cost, and step is many, and efficient is low, and repeatedly dismounting also causes the damage of Sealing easily.
Summary of the invention:
The utility model purpose is to overcome above-mentioned shortcoming, and a kind of compact structure in the test phase use, easy to operate is provided, and the hydraulic jack test buffering that can be fit to different manufacturers type is adjusted structure.
For reaching above-mentioned purpose, the utility model adopts following technological scheme:
The hydraulic jack buffering test is adjusted structure, comprise the piston rod 1 that cooperatively interacts, cylinder cap 2, cylinder body 3, cushion collar 4, piston 5, Sealing 6 and auxiliary 8, be communicated with inside and outside the cylinder buffering test of oil circuit and adjust structure 7 being provided with on cylinder cap or the cylinder body, described buffering test is adjusted structure 7: offering the hole 71 that is communicated with oil circuit inside and outside the cylinder on cylinder cap or the cylinder body, stop valve 72 is arranged in the hole 71, stop valve is provided with adjusts hole 721, spring 73 is arranged in the stop valve 72, spring seat 74 covers above spring 73, plug screw 75 is arranged on outside cylinder body or the cylinder cap, the lower end withstands on spring seat 74 tops and withstands spring seat 74, and O shape circle 76 is arranged between plug screw 75 and cylinder cap or the cylinder body and seals.
Adopt technique scheme, the utility model is adjusted the buffer gap size for convenience, with relevant position on the cylinder body buffering regulating mechanism is set at cylinder cap, need not take oil cylinder apart and change component.Described buffering regulating mechanism is made up of stop valve, spring, spring seat, O shape circle and plug screw, and easy-to-operat personnel directly adjust outside cylinder body.
Description of drawings:
Below with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model structural representation one;
Fig. 2 is the utility model structural representation two;
Fig. 3 is the schematic representation of the utility model buffer structure.
Embodiment:
Below in conjunction with drawings and Examples the utility model is described in detail:
Shown in Fig. 1-3, be embodiment of the present utility model, the hydraulic jack buffering test is adjusted structure, comprise the piston rod 1 that cooperatively interacts, cylinder cap 2, cylinder body 3, cushion collar 4, piston 5, Sealing 6 and auxiliary 8, be communicated with inside and outside the cylinder buffering test of oil circuit and adjust structure 7 being provided with on cylinder cap or the cylinder body, described buffering test is adjusted structure 7: offering the hole 71 that is communicated with oil circuit inside and outside the cylinder on cylinder cap or the cylinder body, stop valve 72 is arranged in the hole 71, stop valve is provided with adjusts hole 721, spring 73 is arranged in the stop valve 72, spring seat 74 covers above spring 73, plug screw 75 is arranged on outside cylinder body or the cylinder cap, the lower end withstands on spring seat 74 tops and withstands spring seat 74, and O shape circle 76 is arranged between plug screw 75 and cylinder cap or the cylinder body and seals.
When carrying out buffering test, according to Measurement results, the technician just can directly take out spring by twisting plug screw outside oil cylinder, change stop valve, assemble buffering more in order and adjust structure, by interporal lacuna 721 sizes of change stop valve, thereby realize that the adjustment of buffer gap reaches the change of cushioning effect.In the time of only can't reaching the cushioning effect requirement all the time, just need tear cylinder exchange buffering cover open and adjust test again in cylinder cap, cylinder body buffer gap.Like this, both need not disassemble oil cylinder from complete machine, also need not want frequent dismounting oil cylinder, reduce the damage of components situation that assembling and dissembling process causes, reduce the auxiliary time and the construction cycle of installation test, improve efficient greatly.
The utility model is applicable to reach when producing in batches in new product installation test in the oil hydraulic cylinder industry and uses; it is a kind of easy to adjust, efficient structure efficiently; utilize the technical solution of the utility model; those skilled in the art designs the similar techniques scheme; reaching above-mentioned technique effect, all is fall into protection domain of the present utility model.
