Abstract
The utility model discloses a nitrogen spring cylinder body welding structure. The nitrogen spring cylinder body welding structure is characterized in that a cylinder barrel and an end cover are arranged to be of a split structure and are connected in a welding mode. Due to the fact that the cylinder barrel and the end cover of a cylinder body of the nitrogen spring cylinder body welding structure are of the split structure and are connected in the welding mode, after being matched in a threaded mode, the cylinder barrel and the end cover are welded together. The structure is simple, machining is convenient, materials are saved, and cost is low.
Description
Technical field
The utility model relates to nitrogen spring, relates in particular a kind of nitrogen spring cylinder body welded structure.
Background technique
Nitrogen spring is a kind of novel spring that stamping part die ejects workpiece in the machinery industry, and it is sealed in high pressure nitrogen in the fixing container, and external force is compressed nitrogen by piston rod, expands to obtain certain elastic force pressure by high pressure nitrogen when external force is removed.Existing nitrogen spring, its structure generally comprise several parts of cylinder body, piston, piston rod, inflatable component and auxiliary device.Nitrogen spring has the advantages such as volume is little, and elastic force is large, and the life-span is long, and elastic force pressure is constant.
Traditional nitrogen spring cylinder body is that integral body processes, and processing technology is complicated, cost is high and caused the serious waste of material.
The model utility content
The utility model is for avoiding the existing deficiency of above-mentioned prior art, a kind of nitrogen spring cylinder body welded structure is provided, so as effectively economical with materials, simplify technique, save cost.
The utility model is that the technical solution problem adopts following technological scheme:
The welded structural feature of the utility model nitrogen spring cylinder body is: cylinder barrel and end cap are set to Split type structure and by being welded to connect.
The welded structural feature of the utility model nitrogen spring cylinder body also is: described cylinder barrel and described end cap pass through screw-thread fit.
The link position place of described cylinder barrel and described end cap is provided with respectively chamfering and forms soldered, welds at described soldered place.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the steel cylinder of the utility model cylinder body and end cap are set to Split type structure, and be simple in structure by welding together after the screw-thread fit, easy to process, and it is low to save material and cost;
2, the utility model steel cylinder and end cap adopt screw-thread fit, the location when being convenient to weld;
3, the link position place of the utility model steel cylinder and end cap all is processed with chamfering, so that welding is more firm.
Description of drawings
Fig. 1 is the utility model general structure schematic representation;
Fig. 2 is the utility model housing structure schematic representation;
Fig. 3 is the utility model end cover structure schematic representation;
Number in the figure: 1 cylinder body; 2 end caps.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the welded structural feature of nitrogen spring cylinder body is in the present embodiment: cylinder barrel 1 and end cap 2 are set to Split type structure and by being welded to connect.Cylinder barrel 1 and end cap 2 pass through screw-thread fit.The link position place of cylinder barrel 1 and end cap 2 is provided with respectively chamfering and forms soldered, welds at the soldered place.
Cylinder body, end cap adopt the split setting, so that spring simple possible has more in the preparation also been saved simultaneously material.Cylinder body, end cap not only make both connections tightr by screw-thread fit, and the location when being convenient to both and welding.Be processed with 45 ° of chamferings on cylinder body, the end cap, so that both are more firm, attractive in appearance when welding.
