Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to piston detection technical field, concretely relates to a piston head volume detection device. BACKGROUND
[0002] Piston head volume is an important item, and influences the compression ratio of the engine. For the head plane and the concave combustion chamber structure, the glass cover plate with holes can be directly covered on the piston top surface, and the titration meter is used for measurement. For the piston head shape as convex, the complex structure, then cannot directly measure. SUMMARY
[0003] The utility model discloses a kind of piston head volume detection devices, to overcome the deficiency of prior art.
[0004] To achieve the above object, the utility model adopts the following technical solutions:
[0005] A kind of piston head volume detection device, including annular volume fixture, transparent cover plate and block gauge, the block gauge is three, three block gauge is equidistantly arranged along the circumferential direction, one end of three block gauge is inserted in the annular groove of the uppermost piston along the circumferential direction, the annular volume fixture is matched and set in the upper end ring bank of piston, the bottom of annular volume fixture is supported on three block gauge, the transparent cover plate has titration hole, transparent cover plate is placed in the top of annular volume fixture, and transparent cover plate and annular volume fixture enclose the head structure of piston.
[0006] Further, the transparent cover plate is glass cover plate.
[0007] The utility model adopts the above technical scheme, and annular volume fixture is positioned in annular groove and ring bank using block gauge, cooperate transparent cover plate, adopt titration measurement to accurately and simply measure the piston head volume of head shape as convex, complex structure. BRIEF DESCRIPTION OF DRAWINGS
[0008] The utility model is further explained in detail as follows in combination with the drawings and specific embodiment:
[0009] Fig. 1 It is front view of the utility model;
[0010] Fig. 2 It is top view of the utility model. DETAILED DESCRIPTION
[0011] As Figs. 1-2As shown, the utility model discloses a piston head volume detection device, including annular volume fixture 1, transparent cover plate 2 and block gauge 3, wherein, transparent cover plate 2 is glass cover plate, and block gauge 3 is three, three block gauge 3 are along the circumferential direction equidistant arrangement, and one end of three block gauge 3 is along the circumferential direction and is matched and is inserted in the ring groove of the uppermost piston 4, and annular volume fixture 1 is matched and is set in the upper end ring bank of piston 4 outside, and the bottom of annular volume fixture 1 is supported on three block gauge 3, and transparent cover plate 2 has titration hole. Transparent cover plate 2 is placed in the top of annular volume fixture 1, and transparent cover plate 2 and annular volume fixture 1 enclose the head structure of piston 4 in.
[0012] The working principle of the utility model: annular volume fixture 1 utilizes block gauge 3 to carry out positioning in the ring groove and ring bank of the uppermost piston, and is matched with transparent cover plate 2 to enclose the head structure of piston 4 in, then adopts titration meter to drop liquid into the titration hole of transparent cover plate 2, after liquid fills the space between annular volume fixture 1 and transparent cover plate 2, the volume of titration liquid consumed is piston 4 head volume.
[0013] The above describes the specific embodiment of the utility model, but the person skilled in the art should understand that this is only illustrative, and the person skilled in the art can make multiple changes or modifications to this embodiment without departing from the principles and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
