Description
Technical field
This utility model relates to a kind of disc spring double-acting shock absorber, belongs to and creeps into aid technical field.
Background technology
As shown in Figure 2, existing amortisseur mainly uses hydraulic structure, but hydraulic structure is high to sealing and the requirement of strength of product self, if processing can not meet product design requirement, being easy to affect properties of product, its deficiency shows: 1. the oily plug-hole crudy on fluid cylinder is bad, easily causes leakage of oil, leakage of oil must affect the stroke of piston, causes the elastic deformation of drilling tool to be difficult to control；The oil cylinder of the most existing instrument is up to 3200mm, the place matched with piston in cylinder bore surface have to honing and chromium plating, endoporus necessarily requires smooth and wear-resisting, processing is all brought difficulty by these, and the longest difficulty of processing of part is the biggest, even beyond the ability of common process, the most virtually add the danger of processing；3. filling silicone oil in oil cylinder, silicone oil is compressed in sap cavity, and whole sap cavity can form high pressure chest, and this proposes very high request to comprcssive strength and the material property of fluid cylinder.
Summary of the invention
The purpose of this utility model is: provides and a kind of reduces drilling tool vibrations, extends drilling tool service life, improves the disc spring double-acting shock absorber of drilling efficiency, to overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of disc spring double-acting shock absorber, including shaft assemblies and be arranged on the sleeve assembly on shaft assemblies outer wall, described shaft assemblies is by mandrel and is connected to the washing pipe of mandrel end section and forms, oil cylinder that the spline body that described sleeve assembly is threadeded with righting sleeve by righting sleeve is threadeded with spline body and be threaded in oil cylinder end and the lower contact that is slidably matched with washing pipe forms；Described spline body is connected with piston by spline pair, piston is arranged between the outer wall of shaft assemblies and the inwall of sleeve assembly, piston inner wall one end is connected with mandrel outer wall thread by multithreading big pitch rectangular thread, it is provided with little disc spring between end and the end of washing pipe of the piston other end, between the shoulder and the end of lower contact of washing pipe outer wall, is provided with big disc spring.
Described piston one end is provided with multithreading big pitch rectangle female thread, and piston is connected by multithreading big pitch rectangle female thread pitch big with the multithreading on mandrel outer wall rectangle external screw thread.
Being provided with big nut in the middle part of mandrel in the draw-in groove of outer wall, big nut is together by a threaded connection with semi-ring.The most just can prevent sleeve assembly from exiting from shaft assemblies by the position-limiting action of semi-ring.
The end of described piston is provided with rotating ring, and little disc spring is arranged between rotating ring and the end of washing pipe.
Owing to using technique scheme, the utility model has the advantage of: this utility model have employed disc spring as damper element, when drill bit produces extensional vibration and rotational vibration in drilling process, the extensional vibration of drilling tool acts in big disc spring by lower contact, rotational vibration is then converted into extensional vibration by piston changement and acts in little disc spring by rotational vibration, and little disc spring can effectively absorb the vibrational energy that these are harmful, store or be converted into the energy of other form, reduce the fatigue damage of drilling tool, reach to protect drilling tool, improve rate of penetration, reduce the purpose of drilling cost.Meanwhile, this utility model uses disc spring replacement silicone oil as damper element, fluid pressure type become mechanical type, reduce the internal pressure strength in whole damper oil cylinder, it is to avoid the high internal pressure damage to rubber sealing element, increase the reliability and stability of whole amortisseur.Additionally, due to do not use silicone oil as transmission medium, reduce the oil cylinder requirement to oil plug-hole, even if oil plug-hole leaks also to cause the function of whole amortisseur at work directly affect.Therefore, this utility model not only makes the length dimension of whole amortisseur be greatly shortened, and while having saved processing cost, also reduces difficulty of processing, also reduces the amortisseur dependency to sealing property so that the reliability of product is greatly improved.
Accompanying drawing illustrates,
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of existing amortisseur.
Description of reference numerals: 1 mandrel, 2 righting sleeves, 3 big nuts, 4 semi-rings, 5 spline bodies, 6 pistons, 7 rotating rings, 8 little disc springs, 9 washing pipes, 10 oil cylinders, 11 big disc springs, 12 lower contacts.
Detailed description of the invention,
In order to make this utility model purpose, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
Embodiment of the present utility model: the structural representation of disc spring double-acting shock absorber is as shown in Figure 1, including shaft assemblies and be arranged on the sleeve assembly on shaft assemblies outer wall, described shaft assemblies is by mandrel 1 and is connected to the washing pipe 9 of mandrel 1 end and forms, oil cylinder 10 that the spline body 5 that described sleeve assembly is threadeded with righting sleeve 2 by righting sleeve 2 is threadeded with spline body 5 and be threaded in oil cylinder 10 end and the lower contact 12 that is slidably matched with washing pipe 9 forms；Described spline body 5 is connected by the piston 6 between spline pair with the outer wall being arranged on shaft assemblies and the inwall of sleeve assembly, described piston 6 inwall one end is provided with multithreading big pitch rectangle female thread, piston 6 is connected with the multithreading big pitch rectangle external screw thread on mandrel 1 outer wall by multithreading big pitch rectangle female thread, the end of piston 6 other end is provided with rotating ring 7, little disc spring 8 is arranged between the end of rotating ring 7 and washing pipe 9, is provided with big disc spring 11 between the shoulder and the end of lower contact 12 of washing pipe 9 outer wall.Being provided with big nut 3 in the middle part of mandrel 1 in the draw-in groove of outer wall, big nut 3 is together by a threaded connection with semi-ring 4.The most just can prevent sleeve assembly from exiting from shaft assemblies by the position-limiting action of semi-ring 4.
During use, the mandrel 1 on shaft assemblies is connected with drill string, the lower contact 12 of sleeve assembly end is connected with drill bit；When drill bit is gone into the well and is crept into, just drill bit can be made to produce extensional vibration be transferred in big disc spring 11 by lower contact 12, big disc spring 11 compression absorbs extensional vibration, the rotational vibration that drill bit produces then is delivered on spline body 5 by lower contact 12 and oil cylinder 10, it is delivered on piston 6 by spline body 5 again, now rotational vibration is converted into extensional vibration by the big pitch rectangular thread of the multithreading between mandrel 1 and acts in little disc spring 8 by piston 6, little disc spring 8 is compressed absorbing extensional vibration, thus reaches the purpose of damping.Further, the end of piston 6 is provided with rotating ring 7, little disc spring 8 is arranged between the end of rotating ring 7 and washing pipe 9, the most just rotational vibration can be converted into extensional vibration by piston 6 by multithreading big pitch rectangular thread by the rotational vibration that drill bit produces, and be transferred in little disc spring 8 by rotating 7 rings, rotating ring 7, between piston 6 and little disc spring 8, reaches to reduce the purpose of spin friction damping.
