Abstract
The utility model discloses a piston rod of a piston cylinder, which comprises a tubular piston rod body, wherein both ends of the piston rod body are provided with a piston rod plug plunger and a piston rod plunger head. The utility model has stronger bending resistant performance, can greatly enhance the quality and prolong the service life of the piston rod of a piston cylinder, and lowers the material consumption.
Description
Technical field
The utility model relates to a kind of piston apparatus, especially relates to a kind of piston rod of piston cylinder.
Background technique
At present, the single action piston cylinder that the dump truck lifting is used on the market, piston rod are all with round steel processing, as the piston rod that adopts very general 45# round steel to process, its structure is respectively equipped with the piston rod column cap and the piston rod plunger of one as shown in fig. 1 at the two ends of piston rod.The piston cylinder piston rod of said structure, it in use has piston rod bending deflection phenomenon, will have influence on piston cylinder and in a single day bending deflection appear in piston rod, and can cause scrapping of piston cylinder, causes waste.
Summary of the invention
Technical problem to be solved in the utility model has provided a kind of stronger bending resistance that has, thereby can improve the quality of piston cylinder piston rod and the piston cylinder piston rod in working life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of piston cylinder piston rod, this piston rod comprise the piston rod body of rod of tubulose, and the two ends of the described piston rod body of rod are respectively equipped with piston rod plunger and piston rod column cap.
As a kind of improvement, an end of described piston rod plunger and piston rod column cap is set in respectively in the described piston rod body of rod tube chamber and with the described piston rod body of rod fixedlys connected.
As further improvement, described piston rod plunger and piston rod column cap and the welding of the described piston rod body of rod are fixing.
As further improvement, the tubular piston club shaft that the described piston rod body of rod is made for the weldless tube that adopts material 27SiMn.
The piston cylinder piston rod of technique scheme, owing to be to have adopted piston rod to comprise the piston rod body of rod of tubulose, the two ends of the piston rod body of rod are respectively equipped with piston rod plunger and piston rod column cap, this structure has not only improved the bending resistance of piston rod, also reduced materials consumption, adopt an end of piston rod plunger and piston rod column cap to be set in respectively in the piston rod body of rod tube chamber and and fixedlys connected, very simple and convenient of processing with the piston rod body of rod.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the structural representation of existing piston cylinder piston rod;
Fig. 2 is the utility model piston cylinder piston rod construction schematic representation.
Embodiment
As shown in Figure 1, the existing piston cylinder piston rod is with 45# round steel processing, and two ends are respectively equipped with piston rod plunger 1 and piston rod column cap 3, and piston rod plunger 1 and piston rod column cap 3 adopt whole processing with the piston rod body of rod.Said structure in use is prone to piston rod bending deflection phenomenon, in case piston rod bending deflection will damage oil cylinder, causes oil cylinder to be scrapped.
As shown in Figure 2, the utility model piston cylinder piston rod, this piston rod comprises the piston rod body of rod 2 of tubulose, the two ends of the piston rod body of rod 2 are respectively equipped with piston rod plunger 1 and piston rod column cap 3, being connected and fixed of the piston rod body of rod 2 of piston rod plunger 1 and piston rod column cap 3 and tubulose, adopt an end of piston rod plunger 1 and piston rod column cap 3 to be set in the piston rod body of rod 2 tube chambers respectively and the mode of fixedlying connected with the piston rod body of rod 2, and piston rod plunger 1 and piston rod column cap 3 can adopt the fixing mode of welding with the piston rod body of rod 2, process simple and convenient.The material of the piston rod body of rod 2 can adopt the weldless tube of 27SiMn to make.Add man-hour, can be according to the needs of producing, selecting material for use is the piston rod body of rod that the thick-wall seamless of 27SiMn is processed into tubulose, then in piston rod body of rod tube chamber behind the car seam, with piston rod plunger 1 and piston rod column cap 3 and tubular piston club shaft hot charging, the assembling back guarantees weldquality with the welding of high strength welding wire, and the postwelding quenching with Subsequent tempering gets final product.The piston cylinder piston rod adopts structure of the present utility model, can reduce materials consumption 20%, and has improved the resistance to flexure of piston rod greatly.
More than be the application's a embodiment, should be understood that these embodiments only are used to the present invention is described and are not used in to limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
