Description
Technical field
The utility model relates to a kind of fuel tank, specifically refers to the whole brace panel of fuel tank mounting hole.
Background technology
The function of fuel tank is mainly to store fluid, plays in addition the effects such as bubble in heat radiation, oil and water separation, precipitated impurities.Fuel tank in hydraulic efficiency pressure system has two kinds of overall formula and separation types, and overall formula is to utilize machinery and equipment fuselage inner chamber as fuel tank (such as die-cast machine, injection machine etc.), compact conformation, and leakage of oil is everywhere easy to reclaim, but inconvenient maintenance, radiating condition is bad; Separation type is that an independent fuel tank is set, separate with main frame, reduce fuel tank heating and the impact of hydraulic power source vibration on operating accuracy, therefore obtained general application, particularly on unit type machine, automation line and accurate mechanical equipment, mostly adopted separation type fuel tank.
Fuel tank must have enough Rigidity and strengths, generally uses the Plate Welding of 2.5 ~ 4mm to form, and the tall and big fuel tank of size will be welded with gusset, strengthening rib increases rigidity.When fuel tank upper cover plate is installed electric motor drive device, Hydraulic Pump and other Hydraulic Elements, the upper and lower two-part mounting hole place of fuel tank can cause because of vibration stress dispersion, the local stress around mounting hole higher, make the sheet material at mounting hole place occur fatigue cracking, crackle is spread to surrounding by the fillet surfaces externally and internally of mounting hole, finally cause fuel tank leak tightness to weaken, casing top and the bottom connect unstable.
Utility model content
The utility model provides fuel tank mounting hole whole brace panel, solves the problem that fuel tank mounting hole surrounding structural strength causes leak tightness to weaken not, the object that reach protection fuel tank, increases the service life.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises upper box and lower box, the equal corresponding a plurality of mounting holes that are provided with in two ends of upper box and lower box, upper box is connected by mounting hole bolt with lower box, also comprise the brace panel that end, lower box two ends is set, on brace panel, have a plurality of through holes, through hole and described mounting hole coaxially arrange, the end welding of described brace panel and lower box.The casing of fuel tank is bolted and is formed by upper box and lower box, and the two ends of upper box and lower box are corresponding is provided with a plurality of mounting holes, and bolt seals casing through mounting hole; Top at upper box is typically provided with the Hydraulic Elements such as oil pump, for avoiding Hydraulic Elements to occur because vibration causes the phenomenon that the leak tightness between upper box and lower box weakens, end, two ends at lower box is welded with brace panel, end construction is carried out to consolidation process, a plurality of through holes that have on brace panel are corresponding one by one with the mounting hole of upper box, lower box end, and convenient operation personnel are fixed and seal fuel tank rapidly and accurately; The brace panel arranging is as a whole; can reinforce the end, two ends of whole lower box; improving all mounting holes stress around concentrates; but not under single mounting hole, carry out independent reinforcing; thereby the whole working strength of hermetic unit is increased; avoid local stress higher and cause the junction of upper box and lower box to occur crackle, protected well fuel tank, extended its service life.
Further, the size of described mounting hole and through hole is measure-alike.On brace panel, the setting of a plurality of through holes has higher alerting ability, applicable to the bolt in the situations such as spacing varies in size between mounting hole quantity difference, mounting hole, connects, and practicality is high; The size of mounting hole is identical with clear size of opening, is convenient to lower box in the quick connection of bolt, is convenient to sealing.
Further, the junction between described upper box and lower box is also provided with packing seal.Upper box is connected with lower box bolt, gets final product good seal fuel tank, between upper and lower casing junction, packing seal is set, and can when strengthening fuel tank sealing property, protect the physical construction of upper and lower tank ends end, avoids it impaired.
Further, described brace panel is circular arc.Because fuel tank profile is different, brace panel is welded on the end of lower box, and its shape can be circular arc, also can be ellipse or I-shape.
Further, as preferably, the material of described brace panel is PH15-7Mo steel.PH15-7Mo steel is to separate out fine intermetallic compound and some a small amount of carbide metal to produce precipitation hardening by heat treatment, and the high strength stainless steel that acquisition high strength and certain corrosion stability combine, belong to semiaustenitic precipitation-hardening stainless steel, this steel obtains austenite structure in room temperature after solution treatment, be easy to machine-shaping, and there is high tenacity, the high corrosion-resistant of austenitic stainless steel.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises upper box and lower box, the equal corresponding a plurality of mounting holes that are provided with in two ends of upper box and lower box, upper box is connected by mounting hole bolt with lower box, also comprise the brace panel that end, lower box two ends is set, on brace panel, have a plurality of through holes, through hole and described mounting hole coaxially arrange, the end welding of described brace panel and lower box.The brace panel arranging is as a whole; can reinforce the end, two ends of whole lower box; improving all mounting holes stress around concentrates; but not under single mounting hole, carry out independent reinforcing; thereby the whole working strength of hermetic unit is increased; avoid local stress higher and cause the junction of upper box and lower box to occur crackle, protected well fuel tank, extended its service life.
2, the material of brace panel of the present utility model is PH15-7Mo steel.PH15-7Mo steel is to separate out fine intermetallic compound and some a small amount of carbide metal to produce precipitation hardening by heat treatment, and the high strength stainless steel that acquisition high strength and certain corrosion stability combine, belong to semiaustenitic precipitation-hardening stainless steel, this steel obtains austenite structure in room temperature after solution treatment, be easy to machine-shaping, and there is high tenacity, the high corrosion-resistant of austenitic stainless steel.
