Abstract
The invention relates to a piston rod and a processing method thereof. The piston rod comprises a first end cap and a second end cap, a large steel tube is arranged between the first end cap and the second end cap, a small steel tube which is fixedly connected with the large steel tube is arranged inside the large steel tube, and the small steel tube penetrates through the first end cap. The piston rod and the processing method thereof have the advantages that first, the small steel tube replaces a traditional sensor mounting hole, according to the mode, the small steel tube is welded inside the large steel tube, the process of hole drilling is removed, the quality of the piston rod can be effectively guaranteed, and the processing efficiency is high; second, according to the piston rod, a solid structure is changed into a hollow structure, used materials are saved, meanwhile, according to mechanics, the rigidity of the hollow structure is improved compared with that of the solid structure, and the service life can be prolonged.
Description
Technical field
The present invention relates to a kind of piston rod and processing method thereof, particularly relate to a kind of piston rod and processing method thereof of inner sensor installation.
Background technique
Sensor installation in existing a kind of piston rod, to adapt to the required of some occasions; Existing processing mode will be for will get out the installation of sensors hole in the solid piston rod that is wholely set, owing to installing, need, general aperture, installation of sensors hole is little and dark, this has strengthened difficulty of processing undoubtedly, the coaxality of mounting hole is difficult to be guaranteed, and often understands run-off the straight, causes scrapping of piston rod, the work efficiency of mounting hole is low, extremely uneconomical simultaneously; Due to entity, the first waste of material is serious simultaneously; The second rigidity is poor, easily damages.
Summary of the invention
The present invention is directed to above-mentioned defect, purpose is to provide a kind of processing simple, and can effectively guarantee piston rod and the processing method thereof of piston rod quality of processing.
The technical solution used in the present invention is for this reason: the present invention includes plug one, plug two, between plug one, plug two, establish big steel pipe, in big steel pipe, establish the little steel pipe that is connected with big steel pipe, little steel pipe passes plug one.
Described little steel pipe one end is installed on plug one, and the other end is installed on big steel pipe.
The described little steel pipe the other end arranges near plug two.
The described little steel pipe the other end is installed on big steel pipe by connecting plate.
A kind of processing method of piston rod, according to following steps, carry out:
1) at first little steel pipe one end is passed to plug and be welded in the lump on plug one, the other end is welded on connecting plate;
2) the little steel pipe of above-mentioned processing is put into to big steel pipe, then connecting plate is welded on big steel pipe, little steel pipe is fixed, and big steel pipe one end is welded on plug one simultaneously;
3) the big steel pipe the other end is welded on plug two to machine shaping.
Advantage of the present invention is: 1) the present invention has replaced traditional installation of sensors hole with little steel pipe, its mode be by little steel-pipe welding in big steel pipe, deduct drilling operating, the quality of piston rod is effectively guaranteed, and its work efficiency is high; 2) the present invention changes entity into hollow-core construction, has saved the use of material, and simultaneously according to mechanics, hollow-core construction is improved than its rigidity of solid construction, can improve working life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of prior art.
In figure, 1 is that plug two, 2 is that big steel pipe, 3 is that connecting plate, 4 is that little steel pipe, 5 is plug one.
Embodiment
The present invention includes plug 1, plug 21, between plug 1, plug 21, establish big steel pipe 2, in big steel pipe 2, establish the little steel pipe 4 that is connected with big steel pipe 2, little steel pipe 4 passes plug 1.
Described little steel pipe 4 one ends are installed on plug 1, and the other end is installed on big steel pipe 2.
Described little steel pipe 4 the other ends arrange near plug 21.
Described little steel pipe 4 the other ends are installed on big steel pipe 2 by connecting plate 3.
A kind of processing method of piston rod, according to following steps, carry out:
1) at first little steel pipe 4 one ends are passed to plug 1 and are welded on plug 1, the other end is welded on connecting plate 3;
2) the little steel pipe 4 of above-mentioned processing is put into to big steel pipe 2, then connecting plate 3 is welded on big steel pipe 2, little steel pipe 4 is fixing, and big steel pipe 2 one ends are welded on plug 1 simultaneously;
3) big steel pipe 2 the other ends are welded on plug 21 to machine shaping.
