With.
Currently used support cylinder all uses welded type cylinder bottom, due to the design feature of the support cylinder, cylinder barrel outside
There is flanged plate to need to weld, if cylinder bottom also welds, must can only just be done due to axial groove along oil cylinder axial direction bevel
Very shallow, weld strength is not usually very high after welding, cannot be satisfied client and actually uses pressure.In addition welded cylinder bottom with
The weld spacing very little of flanged plate, weld seam are concentrated, and cylinder barrel is caused to deform, and welding section performance is insufficient.And in order to ensure flanged plate
Positioning accuracy, before flanged plate weldering must made allowance, and cylinder bottom will also weld preceding made allowance to meet verticality, postwelding vehicle end together
Face, complex procedures.
For this purpose, in some specific implementation modes of the utility model, bottom plate 90 is threadedly coupled with cylinder barrel 10.By bottom plate 90
The design being threadedly coupled with cylinder barrel 10 then avoids this problem, and in actual production, the direct vehicle of flanged plate postwelding positions end face, then
Processing cylinder bottom side screw thread.The installation procedure of the structure is simple, and precision is higher, and connection is also relatively reliable.
It is further to note that traditional support cylinder is all the gusset of first welded flange positioning plate in production, then
Scraping tumbling or hone endoporus, then weld oil pipe.But due to 100 size of the support cylinder of the utility model embodiment that follows up
Greatly, so needing many gussets, gusset postwelding welds oil pipe, therefore, according to the support of the utility model embodiment without space
One section of bottom oil pipe is welded on cylinder barrel 10 by oil cylinder 100 together with connecting seat in advance using connecting seat, then welds gusset, then
Hone endoporus, then some row oil pipes of upper end are welded, it avoids oil pipe and interferes with gusset welding.
To sum up, according to the support cylinder 100 of the utility model embodiment, by the way that traditional is directly installed on cylinder barrel
Guide sleeve on 10 is divided into 50 two parts of guide part 40 and gland, and guide part 40 is for being oriented to piston rod 30, gland 50
It can be used for guide part 40 being fixed on cylinder barrel 10, the two split settings, not only positioning is reliable, avoids stress concentration, and
Big part is greatly small, and the parts after fission are all smaller, do not cause processing difficulties not only, improve parts instead
Machining accuracy, can be applied to the cylinder barrel 10 that internal diameter reaches 250mm.
