Abstract
The utility model provides a special tool for dismantling the gas valve of an internal combustion engine, which is characterized in that the special tool includes a lever, a vertical rod fixed on the front end of the lever and a bushing which is movably connected with the lower end of the vertical rod, wherein, the lever behind the vertical rod is movably provided with another vertical rod, and the lower end of the vertical rod has a gas valve pressing disc. The center of the gas valve pressing disc has a through hole. When disassembling the gas valve, the bushing is sleeved on a bolt at a cylinder head of the internal combustion engine, and then a screw cap is screwed to form a pivot. The gas valve pressing disc is put on a spring tray above a gas valve spring, and the lever is pressed down by one hand, thus the gas valve spring is pressed down by the gas valve pressing disc, and a tapered block is picked out by a screwdriver on the other hand. When in assembly, most procedures are similar to the foresaid ones, whereas, the different procedures include that when the spring is pressed down, the tapered block is recovered into a choke of a valve rod of the gas valve, so that the processes of both assembly and disassembly take little time and labor and can be done by one person.
Description
Affiliated technical field
The utility model relates to a kind of specific purpose tool of dismounting Diesel Engine's Air Valve, specifically to the improvement of existing dismantling device structure.
Background technology
In the maintenance work of internal combustion engine, generally need dismounting inlet and outlet valve down, grind, to keep air-tightness.In disassembly process, need earlier spring for valve to be depressed, take out the circular cone in the valve rod, just air valve and spring can be pulled down.Because spring force is very big, during dismounting, must adopt specific purpose tool just can finish.And existing dismantling device as shown in Figure 1, during dismounting, needs two people to assist to cooperate and just can finish, and wherein a people with the hands is held in pressing spring under the specific purpose tool two ends, and another human screwdriver is chosen circular cone, time-consuming, the effort of disassembly process, inefficiency.For this reason, service worker repeatedly reflects, wishes the technical scheme that design as early as possible makes new advances.
Summary of the invention
The utility model is to solve problems such as the dismounting air valve circular cone that prior art exists is time-consuming, effort.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is: a kind of Diesel Engine's Air Valve tool specially for attaching and detaching, it is characterized in that: it comprises a lever, the front end of lever is fixed with a vertical bar, one sleeve pipe is connected vertical bar lower end versatilely, on vertical bar lever backward a vertical bar is housed versatilely also, this vertical bar lower end is the air valve platen, is through hole in the middle of the air valve platen.
Distance between the described two vertical bars and suitable by the distance between dismounting air valve and the cylinder head bolt.
Be fixed with a U-loop on union body, sleeve pipe is connected on the vertical bar by this U-loop.
Be fixed with a U-loop on lever, vertical bar is connected on this U-loop.
Below the air valve platen, rubber blanket is housed.
The utility model compared with prior art has the following advantages and good effect: when 1, pulling down air valve, with casing pipe sleeve on the IC engine cylinder hook bolt, the nut of screwing on then, form a fulcrum, the air valve platen is placed on the spring holder above the spring for valve, proficiency is depress lever firmly, and the air valve platen is depressed spring for valve, and another hand can be chosen circular cone with screwdriver.Equally, during installation, all the other steps are the same, and different step is behind the pressing spring, circular cone to be reset in the necking down of air valve valve rod instantly.This shows that whole dismounting process is laborsaving, save time, and need only a people just can finish.2, at air valve platen lower surface rubber blanket is installed, can protects spring holder not to be damaged.3, simple and practical, processing and manufacturing is easy, and cost is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the front view of prior art;
Fig. 2 is a front view of the present utility model.
1, lever; 2, vertical bar; 3, sleeve pipe; 4, vertical bar; 5, air valve platen; 6, cylinder head bolt; 7, U-loop; 8, U-loop; 9, rubber blanket; 10, through hole; 11, air valve tool specially for attaching and detaching.
The specific embodiment
Referring to Fig. 2, air valve tool specially for attaching and detaching of the present utility model mark 11.In order to overcome prior art dismounting air valve defective such as waste time and energy, an embodiment of the present utility model is as follows: the front end of lever 1 is fixed with a vertical bar 2, one sleeve pipe 3 that can be sleeved on the cylinder head bolt 6 is arranged, be welded with a U-loop 7 on these sleeve pipe 3 bodies, sleeve pipe 3 is enclosed within vertical bar 2 lower ends versatilely by this U-loop 7.Be fixed with a U-loop 8 on the lever 1 of a segment distance backward at vertical bar 2, vertical bar 4 is enclosed within on this U-loop 8 versatilely, vertical bar 4 lower ends are air valve platen 5, it is an annular, in the middle of the air valve platen 5 is through hole 10, rubber blanket 9 is housed below air valve platen 5, and rubber blanket 9 has elasticity like this, can avoid damaging by pressure spring holder.For the fulcrum (being vertical bar 2) and the distance between the air valve (platen 5) that make lever 1 front end just right, the distance between the two vertical bars 2,4 with should be approximately identical by the distance between dismounting air valve and the cylinder head bolt 6.
When need are pulled down air valve, sleeve pipe 3 is enclosed within on the IC engine cylinder hook bolt 6, the nut of screwing on then forms a fulcrum, and air valve platen 5 is placed on the spring holder above the spring for valve, be held in the handheld terminal of lever 1 on the other hand, depress lever 1 firmly makes air valve platen 5 that spring for valve is depressed, circular cone on the valve rod is exposed after, another hand can be chosen circular cone with screwdriver, so just spring and air valve can be pulled down.The air valve installation process repeats no more.
