Abstract
A floating type buffering oil cylinder belongs to the technical field of oil cylinders and in particular relates to a floating type buffering oil cylinder, which comprises a cylinder barrel, a piston and an oil cylinder tail seat with an oil cylinder tail seat hole. The piston is fixedly connected with a buffering valve core with guiding taper, a buffering valve body is fixedly arranged in the oil cylinder tail seat hole through an annular pressing plate, the buffering valve body can slide in a plane toward any direction, and a plurality of springs are evenly arranged on the lateral face of the buffering valve body. During working of the floating type buffering oil cylinder, the valve core and the buffering valve body are coaxial all the time, thereby fundamentally avoiding the phenomenon of rigid friction especially of a horizontal oil cylinder due to the fact that the buffering core and the buffering valve body are not coaxial. The floating type buffering oil cylinder is reasonable in design, and service life of the oil cylinder is prolonged.
Description
Technical field
The invention belongs to the oil cylinder technical field, be specifically related to a kind of floating-type cushion cylinder.
Background technique
Existing product be generally cone plug directly with the oil cylinder tailstock on cylindrical hole contact, when cone plug entering cylindrical hole, the principle that the sideshake through conical surface and cylndrical surface becomes more and more littler realizes the purpose that cushions.
The damping device of present most oil cylinders is the structures that adopt the tapering spool to cooperate with cylindrical hole; Because oil cylinder is in processing and assembly process; Disalignment error between piston and the oil cylinder tailstock is inevitably, particularly horizontal oil cylinder in use for some time, this phenomenon is more outstanding; Disalignment between the two will inevitably cause the serious friction of surface of contact, even causes pooling feature to lose efficacy.
Summary of the invention
The objective of the invention is: the floating-type cushion cylinder that a kind of long service life is provided.
The objective of the invention is to realize like this: floating-type cushion cylinder; Comprise cylinder barrel, piston and be provided with the oil cylinder tailstock in oil cylinder tailstock hole; Be fixedly connected the buffering spool that has the tapering that leads on the piston; Fixedly install a buffering valve body through annular pressing plate in the oil cylinder tailstock hole, and cushion valve body and can planar do any direction slip, said trimmer valve body side surface evenly is provided with some springs.
Buffering valve body of the present invention is contained in the oil cylinder tailstock hole, fixes through annular pressing plate, and the buffering valve body is the sliding state of joining in the oil cylinder tailstock; Planar can make any direction slides; The trimmer valve body sidewall is uniformly distributed with several radial holes on the surface, in each hole spring is housed, and keeps buffering valve body and oil cylinder tailstock hole coaxial state under the spring normal condition; When skew took place at buffering valve body center, spring can be made tolerant accordingly.Detailed process is: begin after buffering spool tapering microcephaly that piston moved right, was installed in piston end surface gets in the buffering valve body because cushion valve body and spool microcephaly matching gap bigger, at this moment cushion the valve body center and can not produce skew; Suppose that there are disalignment in buffering spool and buffering valve body; When the buffering spool continues operation to the right; Thereby the buffering valve body will overcome the pressure of spring do to float adjustment guarantee the buffering valve body all the time with the coaxality of buffering spool, greatly reduce buffering spool and the frictional force that cushions between the valve body.
In this device busy process; Solved the buffering spool and remained coaxial problem with the buffering valve body; Fundamentally avoided the buffering spool to produce the phenomenon of serious friction with buffering valve body disalignment; Particularly horizontal oil cylinder, the design of this device seems more reasonable, has prolonged the working life of oil cylinder.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the local section sectional view of buffering spool of the present invention.
Embodiment
Like Fig. 1, shown in 2; Floating-type cushion cylinder; Comprise cylinder barrel 1, piston 2 and be provided with the oil cylinder tailstock 7 in oil cylinder tailstock hole, be fixedly connected the buffering spool 3 that has the tapering that lead on the piston 2, fixedly install one through annular pressing plate 4 in the oil cylinder tailstock hole and cushion valve body 6; And buffering valve body 6 can planar be made any direction and slide, and buffering valve body 6 sides evenly are provided with some springs 5.
