Abstract
The invention relates to a piston allowing oil to be scraped conveniently. The piston comprises a piston body, wherein two pin holes are formed in a skirt section of the piston body symmetrically, a piston rod inserting hole extending inwards from the rear portion of the piston body is formed in the piston body, a plurality of sealing circular grooves are formed in the front portion of the piston body, first oil scraping grooves are arranged in the certain positions at the rear ends of the sealing circular grooves, sections of the first oil scraping grooves are in isosceles trapezoid shapes, second oil scraping grooves are arranged in the certain positions at the rear ends of the first oil scraping grooves, sections of the second oil scraping grooves are in step shapes, and oil scraping cotton is arranged in the first oil scraping grooves and the second oil scraping grooves in a matching mode. When the piston body moves backwards, the oil scraping cotton arranged in the first oil scraping grooves and the second oil scraping grooves can scrap oil, oil returns to the piston rod inserting hole through an oil hole, therefore, stability of piston motion is strengthened, oil burning and black smoke are avoided, and service life of the piston is greatly prolonged.
Description
Technical field
The present invention relates to a kind of piston, relate in particular to a kind of piston of being convenient to frizing.
Background technique
Piston is one of critical component in mechanical device, and it works for a long time the in the situation that of high temperature, high load, is bearing mechanical load and the heat load of cycle alternation.The existing piston of being made by cast aluminium, its front portion arranges three closure gasket grooves can be for installing seal ring, on piston only, be also provided with the frizing annular groove of the rectangular shape in rear lateral section that is positioned at closure gasket groove, in piston movement process, this frizing annular groove can not be wiped the fluid being attached on casing wall off completely, and frizing effect is undesirable, has burn oil and over-emitting black exhaust phenomenon, not only the stability of piston movement is affected, and has greatly affected the working life of piston.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of piston of being convenient to frizing.
The present invention is achieved through the following technical solutions:
A kind of piston of being convenient to frizing, comprise piston only, the skirt section of described piston only is arranged with two pin shaft holes, piston only is provided with the piston rod jack extending internally from its rear portion, the front portion of described piston only is provided with some closure gasket grooves, the certain position place, rear end of described closure gasket groove is provided with the first wiper groove, the cross section of described the first wiper groove is isosceles trapezoid, a distance, rear end at the first wiper groove is provided with the second wiper groove, the cross section of described the second wiper groove is stepped, in described the first wiper groove and the second wiper groove, be all placed with the frizing cotton adapting.
As the preferred technical solution of the present invention, the quantity of described closure gasket groove is three, and the distance of adjacent closure gasket groove equates.
As the preferred technical solution of the present invention, the front end of described piston only is provided with chamfering.
Compared with prior art, the invention has the beneficial effects as follows: when piston only is during to rear motion, frizing cotton in the first wiper groove and the second wiper groove all plays the effect of frizing, and fluid is back in piston rod jack through oil-through hole, strengthened the stability of piston movement, avoid occurring burn oil and over-emitting black exhaust phenomenon, greatly extended the working life of piston.

Fig. 2 is the A-A sectional view in Fig. 1;
Fig. 3 is axonometric drawing of the present invention.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 2 and Fig. 3, wherein, Fig. 1 is plan view of the present invention, and Fig. 2 is the A-A sectional view in Fig. 1, and Fig. 3 is axonometric drawing of the present invention.
Described a kind of piston of being convenient to frizing, comprise piston only 1, the skirt section of described piston only 1 is arranged with two pin shaft holes 2, piston only 1 is provided with the piston rod jack 3 extending internally from its rear portion, the front portion of described piston only 1 is provided with some closure gasket grooves 4, the certain position place, rear end of described closure gasket groove 4 is provided with the first wiper groove 5, the cross section of described the first wiper groove 5 is isosceles trapezoid, in a distance, rear end of the first wiper groove 5, be provided with the second wiper groove 6, the cross section of described the second wiper groove 6 is stepped, in described the first wiper groove 5 and the second wiper groove 6, be all placed with the frizing cotton adapting.
The quantity of described closure gasket groove 4 is three, and the distance of adjacent closure gasket groove 4 is equal, and the front end of described piston only 1 is provided with chamfering.
In sum, when piston only 1 is during to rear motion, frizing cotton in the first wiper groove 5 and the second wiper groove 6 all plays the effect of frizing, thereby this piston scrape machine oil better effects if, strengthened the stability of piston movement, avoid occurring burn oil and over-emitting black exhaust phenomenon, greatly extended the working life of piston.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
