Abstract
The utility model relates to an anodizing protective cover of a combustion chamber of a piston. The combustion chamber is arranged at the top end of the piston, and the protective cover is sleeve-like and comprises an upper protective sleeve and a lower protective sleeve, wherein a bump is formed on the inner wall of the upper protective sleeve and the lower protective sleeve is a horn mouth with a downward opening. The anodizing protective cover of the combustion chamber of the piston provided by the utility model is made from an elastic material, can be compactly matched with the piston and is simple in structure and convenient to change within several seconds and low in cost, and satisfies the actual production demand.
Description
Technical field
The utility model relates to a kind of protective sleeve, especially piston combustion bowl anodic oxidation protective sleeve.
Background technology
Piston is the vitals of engine, and during work, because piston is kept in motion always, so it is very easy to damage.Top land is provided with combustion chamber, and in combustion chamber, in gasoline or diesel oil atomization state of combustion, its internal temperature is very high.Therefore, when machining piston, must carry out surface treatment to the combustion chamber of piston, improve that it is high temperature resistant, wear resistance, corrosion resistance, improve its work-ing life.
Conventionally, anodic oxidation need to be carried out in the combustion chamber of piston.But, in surface treatment process, must protect other surfaces of piston.Existing safety guard, in order to improve the work-ing life of safety guard, the metal materials that adopt more, after itself and piston are used in conjunction with, the mating surface of easy damaged piston, the time that clamping need to be longer at every turn (generally needing several hours clampings to change), and safety guard cost is also higher, cannot meet needs of production.
Utility model content
The deficiency that the utility model exists for prior art just, provides a kind of mould sandblast apparatus.
For addressing the above problem, technical solution adopted in the utility model is as follows:
Piston combustion bowl anodic oxidation protective sleeve, described piston tip is provided with combustion chamber, and described protective sleeve is sleeve-shaped, comprises protective sleeve and lower protective sleeve, and upper protective sleeve inwall is provided with protruding block, and lower protective sleeve is downward opening hydraucone.
As the improvement of technique scheme, described upper protective sleeve and piston are shrink-fit, and upper protective sleeve inwall protruding block embeds in the annular groove of piston, and combustion chamber is exposed to top.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Piston combustion bowl anodic oxidation protective sleeve described in the utility model, it adopts elastic material to make, and can closely coordinate with piston, and it is simple in structure, and it is convenient to change, and can complete replacing several seconds, and cost is low, meets needs of production.
Accompanying drawing explanation
Fig. 1 is piston structure schematic diagram described in the utility model;
Fig. 2 is protective sleeve structural representation described in the utility model;
Fig. 3 is that protective sleeve is arranged on the structural representation on piston.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be piston structure schematic diagram described in the utility model.Described piston 10 tops are provided with combustion chamber 11, when anodic oxidation treatment is carried out in combustion chamber 11, need to protect other positions of piston 10.
As shown in Figure 2, be protective sleeve structural representation described in the utility model.Described protective sleeve 20 is made for elastic soft material, can adopt garment bag etc.Protective sleeve 20 is sleeve-shaped, comprises protective sleeve 21 and lower protective sleeve 22.Upper protective sleeve 21 inwalls are provided with protruding block, and lower protective sleeve 22 is downward opening hydraucone.
As shown in Figure 3, for protective sleeve 20 is arranged on the structural representation on piston 10.Upper protective sleeve 21 is shrink-fit with piston 10; piston 10 struts upper protective sleeve 21, and upper protective sleeve 21 inwall protruding blocks embed in the annular groove of piston 10, play like this effect of sealing; the combustion chamber 11 of piston 10 is exposed to top, and other positions of piston 10 are contained in lower protective sleeve 22.
Protective sleeve 20 described in the utility model, can make different size according to the size of piston 10, meets its surface-treated needs.
