Abstract
The utility model discloses a machine frame balancing shaft window part of the plate type water tank of the single cylinder diesel engine. The foresaid structure consists of a tank body. A protuberance protruding towards cavity of the tank body which is integrated with the tank body is arranged on bottom of the tank body which is opposite to the balancing shaft window. A through hole is arranged on edge of the protuberance and opposite to screw hole which is used in connecting the balancing shaft window and the tank body. The utility model also comprises a cover plate which can cover the balancing shaft window on machine body. The cover plate is provided with a protuberance as well. The cover plate covers the protuberance of the tank. Holes which penetrate the cover plate corresponding to the through holes which are arranged around the protuberance of the tank body are arranged on edges of the protuberance of the cover plate. Characteristically, the utility model of proper structure can prevent the water from leaking into the water tank from dropping into the machine body.
Description
Technical field
The utility model relates to the structure at a kind of single cylinder diesel sheet material tank box reply trunnion shaft window position, belongs to the diesel engine manufacturing technology.
Background technique
The succession particularly horizontal single cylinder diesel water tank of single cylinder diesel for a long time all is to adopt cast iron or cast aluminium water tank.
With respect to fuselage trunnion shaft window, be equipped with the projection that is used for not hindering fitting machine body trunnion shaft window cover plate in the bottom surface of existing said water tank.This is for the foundry goods water tank, and its reparation technology is simple and easy and ripe.
Along with the research and development of lightweight in modern age, technology single cylinder diesel, said water tank substitutes foundry goods by the sheet metal product has become developing trend.Such as Chinese patent notice of authorization CN1077647C, adopt sheet metal to make tank box through cold punching technology.The patented product can directly cover organism balance axle window, and former trunnion shaft window covers plate can remove, and is reducing weight, saves cost and improves aspects such as water tank and body connection reliability, all has tangible good effect.But, just because it is to adopt sheet metal to make through cold punching technology, at the pit position that said casing upwards swells with respect to fuselage trunnion shaft window, factors such as tensile buckling that is taken place in the cold punching technology process and existing stress are concentrated, and problems such as casing pit position cracking, perforation can take place inevitably, especially under diesel engine work situation, owing to reasons such as vibrations, it is serious that the cracking problem at said pit position will more become.And the cracking at said casing pit position even the finest crack, all will cause the seepage of water tank, and the cooling water in the water tank will advance in the body by drip, influences the proper functioning of single cylinder diesel.
Summary of the invention
The purpose of this utility model is, a kind of deficiency that can overcome above-mentioned prior art is provided, and prevents that the radiator leak drip from going into the structure at the single cylinder diesel sheet material tank box reply fuselage trunnion shaft window position in the body,
The utility model realizes that the technological scheme of its purpose is:
The structure at a kind of single cylinder diesel sheet material tank box reply fuselage trunnion shaft window position comprises casing; In tank floor with respect to fuselage trunnion shaft window position, be provided with to cabinets cavity protuberance and with the casing projection of one each other, be provided with the through hole of tackling mutually with the set screw that is used for connecting with casing of fuselage trunnion shaft window around projection, its innovative point is: the cover plate that also comprises capping fuselage trunnion shaft window; Cover plate is provided with the cover plate projection, and said cover plate posts at the set boss of casing and with the set boss of casing and fits; Around the set cover plate projection of cover plate, be provided with the cover plate through hole of tackling perforation mutually with the set projection of casing through hole all around.
Can understand by above given technological scheme, the utility model is because it is on the basis of prior art, added the cover plate of capping trunnion shaft window, and especially be provided with under the situation of sealing gasket at cover plate and fuselage trunnion shaft window peripheral bond position, it is exactly the pit position that casing upwards swells with respect to fuselage trunnion shaft window, be the utility model said to cabinets cavity protuberance and with the casing boss of one each other, ftracture, bore a hole, the cooling water in the water tank can not advance in the body by drip yet.That is to say that said water clock water can drop down the outside of body from cover plate.Thereby realized the purpose of this utility model.
Prevent that for further improving the effect that the radiator leak drip is gone in the body from considering that the utility model also is provided with sealed material layer between cover plate and casing.Said sealed material layer can be a rubber gasket, also can be the coating sealer.
In order to make cover plate and casing can be coupled to one, to be easy to install and maintain, the utility model is also with its cover plate and casing welded connection.Said welded connection can be that spot welding connects, when reducing welding consumables and Welder.
After technique scheme was implemented, what the utility model had was rational in infrastructure, and characteristics such as can prevent that the radiator leak drip from going in the body are conspicuous.
Description of drawings

Fig. 2 is the schematic top plan view (slightly amplifying) of the utility model structure position shown in Figure 1.
Embodiment
Shown in accompanying drawing 1,2, the structure at a kind of single cylinder diesel sheet material tank box reply fuselage trunnion shaft window position comprises casing 1; In casing 1 bottom surface with respect to fuselage trunnion shaft window position, be provided with to casing 1 inner chamber protuberance and with casing 1 projection 2 of one each other, around projection 2, be provided with the through hole 3 of tackling mutually, also comprise the cover plate 4 of capping fuselage trunnion shaft window with the set screw that is used for connecting with casing 1 of fuselage trunnion shaft window; Cover plate 4 is provided with cover plate projection 5, and said cover plate 4 posts to account for mutually at set projection 2 positions of casing 1 and with casing 1 set protruding 2 positions and closes; Around cover plate 4 set cover plate projectioies 5, be provided with casing 1 set protruding 2 through hole 3 all around and tackle the cover plate through hole 6 that connects mutually; Between cover plate 4 and casing 1, also be provided with sealed material layer rubber pad 7; Cover plate 4 connects with casing 1 spot-welded on.
Above-mentioned embodiment casing 1 and cover plate 4 material therefors all are sheet metals.But be not limited.Adopt alloy aluminum board making casing 1 selectively and adopt high-temperature resistance plastice to make cover plate 4, also all be fine.
The utility model lab scale first sample was tried out 2000 hours on horizontal evaporation-type single-cylinder diesel engine continuously, and diesel-engine body water inlet problem does not take place.
