Abstract
The utility model discloses a kind of cylinder barrel welded flange hydraulic fluid ports, including being equipped with the cylinder barrel of hydraulic fluid port, the flange connected firmly with cylinder barrel, flange is equipped with oilhole corresponding with hydraulic fluid port and several connecting screw holes, it is characterized in that the flange is connected firmly by the circular weld on the outside of its oilhole with cylinder barrel welding, several connecting screw holes are through-hole and the outside for being located at circular weld；The utility model has the advantages that easy to process, weld seam stress is small, safety is good, and can reduce cost.
Description
Technical field
The utility model relates to a kind of cylinder barrel welded flange hydraulic fluid ports.
Background technique
Currently, cylinder tube mostly uses welded flange hydraulic fluid port to couple oil pipe；Existing cylinder barrel welded flange hydraulic fluid port is such as schemed
1, shown in Fig. 2, including being equipped with the cylinder barrel 7 of hydraulic fluid port, the flange 9 connected firmly with cylinder barrel 7 by the weld seam 8 of edge, flange 9 is equipped with
Oilhole 10 corresponding with hydraulic fluid port and several connecting screw holes 11；The structure since there are a large amount of weld seams on flange 9 periphery, not only process compared with
To be cumbersome, oil liquid enters cylinder barrel 7 and 9 gap of flange, is also subjected to the power of Flange Plane entire area, and the receiving pressure of weld seam 8 is big,
Safety is poor；Flanged joint screw hole 11 cannot be attacked and be worn, and be worn once attacking, oil liquid can by cylinder barrel 7 and 9 gap of flange, connect spiral shell
Hole 11 causes to leak, therefore the thickness of flange 9 is larger, at high cost.
Summary of the invention
The purpose of this utility model is In view of the above shortcomings of the prior art, to provide a kind of cylinder barrel welded flange oil
Mouthful, it has the advantages that, and easy to process, weld seam stress is small, safety is good, and can reduce cost.
In order to achieve the above objectives, a kind of cylinder barrel welded flange hydraulic fluid port of the utility model, including be equipped with hydraulic fluid port cylinder barrel, with
The flange that cylinder barrel connects firmly, flange are equipped with oilhole corresponding with hydraulic fluid port and several connecting screw holes, it is characterised in that the flange passes through
Circular weld on the outside of its oilhole is connected firmly with cylinder barrel welding, and several connecting screw holes are through-hole and the outside for being located at circular weld.
The utility model since flange by circular weld on the outside of its oilhole and cylinder barrel is welded and is connected firmly, not only weld seam it is few,
It is easy to process, and flange is subjected only to the pressure of circular weld inner area, weld seam stress is small, safety is good；And No leakage, Shuo Gelian
Connecing screw hole and caning be processed reduces cost for through-hole to reduce flange thickness；
The flange and cylinder barrel also pass through the sealing weld seam at edge as a further improvement of the utility model, or spotweld is consolidated
Connection；It can play a part of to be auxiliarily fixed, convenient for the welding of circular weld；
The end face of the circular weld and flange as a further improvement of the utility model,；It is easily installed, even
It connects；
In conclusion the utility model has the advantages that easy to process, weld seam stress is small, safety is good, and can reduce into
This.
Detailed description of the invention
Fig. 1 is the main view of existing cylinder barrel welded flange hydraulic fluid port.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the main view of the utility model embodiment.
Fig. 4 is the top view of Fig. 3.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 3, Figure 4, a kind of cylinder barrel welded flange hydraulic fluid port of the embodiment, cylinder barrel 1 and cylinder including being equipped with hydraulic fluid port
The flange 2 that cylinder 1 connects firmly, flange 2 are equipped with oilhole 3 corresponding with hydraulic fluid port and several connecting screw holes 4, and the flange 2 passes through its oilhole 3
The circular weld 5 in outside is connected firmly with the welding of cylinder barrel 1, and the end face of circular weld 5 and flange 2, several connecting screw holes 4 are logical
Hole and the outside for being located at circular weld 5, flange 2 are also connected firmly by the spotweld 6 at edge with cylinder barrel 1.
The utility model is connected firmly since flange 2 is welded by the circular weld 5 in its 3 outside of oilhole with cylinder barrel 1, not only weld seam
Less, easy to process, and flange 2 is subjected only to the pressure of circular weld inner area, weld seam stress is small, safety is good；In addition several companies
Connect the outside that screw hole 4 is respectively positioned on circular weld 5, and No leakage, several connecting screw holes 4 can be processed as through-hole, in connecting screw hole 4
Depth to reduce the thickness of flange 2, reduces cost under the same conditions；Spotweld 6 can play a part of to be auxiliarily fixed, convenient for annular
The welding of weld seam 5.
