Embodiment Construction

[0024] The present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0025] Non-limiting and non-exclusive embodiments will be described with reference to the following drawings, wherein like reference numerals refer to like parts unless specifically stated otherwise.

[0026] Figure 1-3 The shown rotary cylinder head fuel hole position measuring device includes a main body and a detection piece. The main body is a cylinder with a small upper part and a larger lower part. The large end is the embedded end 31 and the small end is the assembly end 3. The embedding end 31 and the assembly end 3 are integrally formed, and the center is coaxial, and the connection between the embedding end 31 and the assembly end 3 forms a stepped surface. Th...

Abstract

The invention discloses a position degree measuring device for a fuel hole of a rotary air cylinder cover. The device comprises a main body and two detection parts; the main body is a cylinder with asmall upper part and a large lower part, the large end is an embedded end, the small end is an assembling end, and a stepped surface is formed at the joint of the embedded end and the assembling end;each detection part comprises a positioning seat and a positioning pin, the front end of each positioning seat is vertically fixed with each positioning pin, and the rear end of each positioning seatis in sliding connection with the assembling end; detection lines mutually corrected in position are arranged on the same sides of the rear ends of the two positioning seats so as to serve as a detection reference; axial positioning grooves are formed in the two sides of the embedded end respectively; and the positioning grooves are used for positioning the positioning pins. The device has the advantages that the structure is simple, the detection is accurate, the abrasion of the fuel hole in a measurement process is effectively reduced, and the like.

Description

technical field [0001] The invention relates to the technical field of engine accessory detection, in particular to a rotary cylinder head fuel hole position measuring device and a method for using the same. Background technique [0002] At present, the two φ4 positioning pin holes in the 6 fuel holes on the air intake surface of the 6J cylinder head are deep and small in diameter, so there is no suitable measuring tool on the machining site. When sending the product to the three-coordinate room for measurement, due to the short length and large diameter of the measuring head of the three-coordinate machine, it is impossible to use the three-coordinate machine to directly measure the position of the two φ4 pin holes, which seriously restricts the quality of the cylinder head fuel hole position. Judging and influencing the production of the cylinder head line. It is particularly important to develop a simple, fast and accurate pin hole position measurement tool. [0003] Th...
