Abstract
The utility model discloses a reduce welding deformation's pneumatic cylinder cylinder, include the cylinder, treat that welding piece and welding link up the piece, the welding links up the piece and fixes on the cylinder, wait to weld a welding on the welding links up the piece. The utility model discloses at the cylinder with treat that the welding has set up the welding between and has linked up, the welding links up the follow -up finish machining that the piece can not influence the cylinder, consequently, the cylinder that causes when fixed welding links up the piece warp can be eliminated at subsequent finish machining in -process, treat after the finish machining, it welds to treat the welding piece again, thereby avoid producing and warp, effective adverse effect who causes the pneumatic cylinder that eliminates, and can replace general pneumatic cylinder with the thin wall pneumatic cylinder under certain condition, and then raw materials for production have been practiced thrift greatly.
Description
Technical field
This utility model relates to a kind of Barrel of Hydraulic Cylinders reducing welding deformation.
Background technology
Some kinds of hydraulic cylinder needs to weld the parts such as oil pipe on cylinder barrel.But cylinder barrel can be caused deform when welding the part such as oil pipe, and owing to the part often structures such as welding oil pipe are complicated, volume relatively greatly, wants that to carry out shaping the most relatively difficult follow-up.
The deformation that welding causes can cause be substantially reduced the service life of hydraulic cylinder, and particularly thin wall type hydraulic cylinder is more prone to be deformed.In order to solve this problem, the cylinder barrel wall of hydraulic cylinder typically can be thickeied by people, not only causes raw-material waste, and affects it and use function.
Utility model content
Barrel of Hydraulic Cylinders that technical problem to be solved in the utility model is to provide a kind of simple in construction, that welding deformation can be reduced.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that the Barrel of Hydraulic Cylinders reducing welding deformation, including cylinder barrel, to-be-welded pieces and welding convergence piece, described welding convergence piece is fixed on cylinder barrel, and described to-be-welded pieces is welded in welding convergence piece.
Further, described to-be-welded pieces is oil pipe, and described welding convergence piece is provided with through hole, and described welding convergence piece is stuck in the outer wall of cylinder barrel and is welded and fixed with cylinder barrel, described cylinder barrel is provided with the oilhole connected with through hole, and one end of described to-be-welded pieces is stretched into through hole and is welded and fixed with welding convergence piece.
Further, described to-be-welded pieces is limiting plate, described welding convergence piece curved curved surface tabular, and described welding convergence piece is welded on the outer wall of cylinder barrel, and described to-be-welded pieces is welded in welding convergence piece.
Further, one end of described cylinder barrel is provided with earring seats.
The beneficial effects of the utility model are:
This utility model is provided with welding convergence piece between cylinder barrel and to-be-welded pieces, welding convergence piece does not interferes with the subsequent fine processing of cylinder barrel, therefore the cylinder barrel deformation caused when fixing welding convergence piece can be eliminated in follow-up finishing passes, after treating polish, again to-be-welded pieces is welded, thus avoid being deformed, effectively eliminate the adverse effect that hydraulic cylinder is caused, and general hydraulic cylinder can be replaced with thin-walled hydraulic cylinder under certain condition, and then it is greatly saved raw materials for production.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1.
Fig. 2 is the structural representation of this utility model embodiment 2.
Being labeled as of each parts in accompanying drawing: 1 cylinder barrel, 11 oilholes, 2 to-be-welded pieces, 3 welding convergence piece, 31 through holes, 4 earring seats.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
See Fig. 1.
The Barrel of Hydraulic Cylinders reducing welding deformation of this utility model embodiment 1, including cylinder barrel 1, to-be-welded pieces 2 and welding convergence piece 3, described welding convergence piece 3 is fixed on cylinder barrel 1, and described to-be-welded pieces 2 is welded in welding convergence piece 3.
This utility model is provided with welding convergence piece 3 between cylinder barrel 1 and to-be-welded pieces 2, during fabrication, first welding convergence piece 3 is fixed on cylinder barrel 1, and to-be-welded pieces 2 is welded on welding convergence piece 3 the most again；When fixing welding convergence piece 3, no matter use which kind of fixed form, such as welding, mechanical attachment etc., can inevitably cause cylinder barrel 1 to deform equally, but owing to cylinder barrel 1 is also had follow-up finishing passes, such as cutting, tumbling, hone etc., comprehend the eliminating deformation that will produce above at these, after treating polish, again to-be-welded pieces 2 is welded in welding convergence piece 3, now weld, be not directly contacted with cylinder barrel 1, thus avoid being deformed.
This utility model welding convergence piece 3 is to play welding linking effect, and its general simple in construction, volume is typically small, and shape and size are as the criterion with the polish not affecting cylinder barrel 1 follow-up.
In the present embodiment, described to-be-welded pieces 2 is oil pipe, described welding convergence piece 3 is provided with through hole 31, described welding convergence piece 3 is stuck in the outer wall of cylinder barrel 1 and is welded and fixed with cylinder barrel 1, described cylinder barrel 1 is provided with the oilhole 11 connected with through hole 31, and one end of described to-be-welded pieces 2 is stretched into through hole 31 and is welded and fixed with welding convergence piece 3.The welding convergence piece 3 of the present embodiment is fixed with cylinder barrel 1 by clamping and welding, more firm than single fixed form, and it is high, more rationally with the fitness of oil pipe.
In the present embodiment, one end of described cylinder barrel 1 is provided with earring seats 4.Earring seats 4 is fixed for carrying out hydraulic cylinder installing.Embodiment 2
See Fig. 2.
The present embodiment is similar to embodiment 1 structure, therefore illustrates only for deviation.Their difference is: described to-be-welded pieces 2 is limiting plate, described welding convergence piece 3 curved curved surface tabular, and described welding convergence piece 3 is welded on the outer wall of cylinder barrel 1, and described to-be-welded pieces 2 is welded in welding convergence piece 3.
The to-be-welded pieces 2 of the present embodiment can form preferable compatible degree with circular cylinder barrel, is that connection between the two is more firm, thus ensures the stability of to-be-welded pieces 2.Limiting plate is equally used for the installation of hydraulic cylinder and fixes.
The most as required, to-be-welded pieces 2 and the welding convergence piece 3 of above two version can be simultaneously used on a cylinder barrel, and this utility model is not limited with above-mentioned.
Be to be understood that example as herein described and embodiment only for explanation, those skilled in the art can make various amendment or change according to it, in the case of without departing from this utility model spirit, broadly falls into protection domain of the present utility model.
