Abstract
The utility model discloses a hydraulic oil cylinder piston, which comprises a piston body and a cam. One end face of the cam is fixed at one end of a piston body, and the end portion of the other end of the cam is provided with threaded holes. A location hole of the cam is communicated with a location hole of the piston body, and the central axes are on the same horizontal line. The cam is arranged on the piston body which is in high strength connection with a piston rod through the cam, and therefore, connection is more reliable, larger pull force can be transmitted, damages such as fatigue and the like can not appear during working projects, service life of the piston is prolonged, simultaneously the piston consumes less energy during use process, and accordingly energy is saved. The surface of the piston body is further provided with an annular sealing groove, and a sealing ring is arranged in the sealing groove, thereby being good in sealing effect and reducing energy consumption. The cam and the piston body are integrally formed, thereby facilitating large-scale industrial production and having high application and popularization value.
Description
Technical field
The utility model relates to a kind of hydraulic jack, particularly a kind of hydraulic cylinder piston.
Background technique
Hydraulic jack is the actuator in the hydraulic system, and generally by cylinder body, piston rod and Sealing are formed; Cylinder interior is divided into two parts by piston, and logical respectively oilhole is because the compression ratio of liquid is very little; So when one of them oilhole oil-feed; Piston will be pushed and make another oilhole fuel-displaced, piston drive piston rod do stretch out, retraction movement, otherwise still.In hydraulic transmission; Its actuator generally is hydraulic jack or oil hydraulic motor; Can convert hydraulic pressure into mechanical energy, in the time of for needs hydraulic pressure being converted into the machinery swing or reverses power, then often need adopt hydraulic jack to realize through corresponding mechanical structure.Most important component are exactly piston in the hydraulic jack; Simultaneously piston also is one of worst key components and parts of operating conditions in the motor, so to the having relatively high expectations of piston, existing piston in use consumes energy more; Waste energy, and the working life of existing piston is shorter.
Summary of the invention
The purpose of the utility model just is a kind of long service life is provided, the hydraulic cylinder piston of less energy intensive in the using process.
To achieve these goals; The technological scheme that the utility model adopts is such: the hydraulic cylinder piston of the utility model, comprise piston only, and also comprise a cam; Cam one end face is fixed on piston only one end; Cam the other end end has screw, and the positioning hole of cam communicates with the positioning hole of piston only, and central shaft is on same horizontal line.
As preferably, said piston only surface is provided with annular seal groove, is provided with seal ring in the seal groove.
As preferably, said annular seal groove is two, is separately positioned on the two ends of piston only.
As preferably, said cam and piston only are one-body molded.
Compared with prior art, the advantage of the utility model is: piston only is provided with cam, and piston only is connected with piston rod high tenacity through the screw on the cam; Connect more reliable; Can transmit bigger pulling force, but in the work engineering, not be prone to strain phenomenons such as fatigue, increased the working life of piston; Make the piston minimizing of in use consuming energy simultaneously, energy saving; The piston only surface is provided with annular seal groove, is provided with seal ring in the seal groove, and good sealing effect reduces power consumption, and seal groove is two, makes the sealing effect of piston better; Cam and piston only are one-body molded, are convenient to large-scale industrial production, have very high use promotional value.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of Fig. 1.
Among the figure: 1, piston only; 2, seal ring; 3, cam; 4, screw.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1 and Fig. 2, the hydraulic cylinder piston of the utility model comprises piston only 1; Also comprise a cam 3, cam 3 one end faces are fixed on piston only 1 one ends, and cam 3 the other end ends have screw 4; The positioning hole of cam 3 communicates with the positioning hole of piston only 1, and central shaft is on same horizontal line, and said piston only 1 surface is provided with annular seal groove; Be provided with seal ring 2 in the seal groove; Said annular seal groove is two, is separately positioned on the two ends of piston only 1, and said cam 3 is one-body molded with piston only 1.
When feeding hydraulic oil in the oil cylinder, piston is outside oil extraction under the promotion of hydraulic oil, because piston only 1 is provided with annular seal groove and seal ring 2, the phenomenon of leakage of oil can not occur; Reduced certain power consumption, piston only 1 is provided with cam 3, and piston only 1 is connected with piston rod high tenacity through the screw 4 on the cam 3; Connect more reliably, can transmit bigger pulling force, be not prone to strain phenomenons such as fatigue in the engineering of but working; Increased the working life of piston, make the piston minimizing of in use consuming energy simultaneously, energy saving; Piston only 1 surface is provided with annular seal groove, is provided with seal ring 2 in the seal groove, good sealing effect; Reduce power consumption, seal groove is two, makes the sealing effect of piston better; Cam 3 is one-body molded with piston only 1, is convenient to large-scale industrial production, has very high use promotional value.
Claims (4)
1. a hydraulic cylinder piston comprises piston only, it is characterized in that: also comprise a cam; Cam one end face is fixed on piston only one end; Cam the other end end has screw, and the positioning hole of cam communicates with the positioning hole of piston only, and central shaft is on same horizontal line.
2. a kind of hydraulic cylinder piston according to claim 1 is characterized in that: said piston only surface is provided with annular seal groove, is provided with seal ring in the seal groove.
