Technical Field
[0001] This utility model relates to a cylinder head combustion chamber depth inspection tool, belonging to the technical field of workpiece quality inspection, specifically to a tool used for detecting the depth of the cylinder head combustion chamber. Background Technology
[0002] The combustion chamber is a device in which fuel or propellant burns to generate high-temperature gas. It is a combustion device made of high-temperature resistant alloy materials. The fuel burns in this chamber, and it is an important component of gas turbine engines, ramjet engines, and rocket engines.
[0003] If the combustion chamber dimensions are not up to standard, it will affect the engine's combustion compression ratio and thus its performance. Therefore, the dimensions of the combustion chamber components need to be inspected during production.
[0004] A cylinder head has multiple combustion chambers, requiring inspection of all of them. This is often done using depth measurement to calculate the volume and determine if the combustion chamber dimensions are up to standard. Currently, the method of measuring and recording each chamber sequentially is inefficient and prone to errors. Utility Model Content
[0005] To address one of the aforementioned technical deficiencies, this utility model provides a cylinder head combustion chamber depth inspection tool that is easy to use, highly efficient, accurate, and less prone to errors.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cylinder head combustion chamber depth inspection tool, including a main beam, positioning beams, a flat positioning head, an X positioning head, a Y positioning head, and a dial indicator. At least three positioning beams are provided on both sides of the main beam along its length. A flat positioning head is fixedly installed on the bottom surface of each positioning beam. An X positioning head is provided on the bottom surface of the end of at least two positioning beams on one side of the main beam along its length. At least one Y positioning head is provided on the bottom surface of one end of the main beam along its length. Multiple dial indicators are fixedly installed on the main beam. The sleeves of all dial indicators are fixed in the vertical through holes opened on the main beam. The measuring rod of the dial indicator is located below the main beam and its body is located above the main beam. When the flat positioning head, X positioning head, and Y positioning head are positioned on the cylinder head, the measuring head of each dial indicator contacts the bottom end of a cylinder head combustion chamber.
[0007] At least three placement support rods are fixedly installed on the top surface of the main beam and the positioning beam, and a support cap is provided at the top of the placement support rod.
[0008] The main beam has handles fixedly installed laterally on both sides along its length.
[0009] The cylinder head combustion chamber depth inspection tool provided by this utility model can perform three-dimensional positioning on the surface of the cylinder head where the combustion chamber is located. It is efficient and convenient, and can directly locate and measure and record the depth of all combustion chambers in one go. The measurement is efficient, accurate and not prone to errors.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] like Figure 1-3 As shown, this utility model's cylinder head combustion chamber depth inspection tool includes a main beam 1, positioning beams 2, a planar positioning head 3, an X-positioning head 4, a Y-positioning head 5, and a dial indicator 6. At least three positioning beams 2 are provided on both sides of the main beam 1 along its length. A planar positioning head 3 is fixedly installed on the bottom surface of each positioning beam 2, meaning at least three planar positioning heads 3 contact the reference plane of the cylinder head combustion chamber surface for Z-axis positioning. An X-positioning head 4 is provided on the bottom surface of at least two positioning beams 2 on one side of the main beam 1 along its length, and at least one Y-positioning head 5 is provided on the bottom surface of one end of the main beam 1 along its length. Moving this utility model allows for the inspection of the depth of the cylinder head combustion chamber depth of the cylinder head combustion chamber. Without detaching from the reference plane, the two X-positioning heads 4 perform X-axis positioning and the Y-positioning head 5 performs Y-axis positioning, thereby realizing the three-dimensional positioning of the quality inspection tool. Multiple dial indicators 6 are fixedly installed on the main beam 1. The sleeves of all dial indicators 6 are fixed in the vertical through holes opened on the main beam 1. The measuring rod of the dial indicator 6 is located below the main beam 1 and its body is located above the main beam 1. When the plane positioning head 3, X-positioning head 4, and Y-positioning head 5 are positioned on the cylinder head, the measuring head of each dial indicator 6 contacts the bottom end of a cylinder head combustion chamber, and the depth of the corresponding combustion chamber can be measured and recorded by each dial indicator 6. Figure 1-3The diagram only shows four dial indicators 6, corresponding to the measurement of the four combustion chambers of the cylinder head. In actual use, different numbers of positioning beams 2 and dial indicators 6 can be set according to the size of the workpiece and the number of combustion chambers. The setting position of the positioning beams 2 is specifically designed according to the reference surface selected according to the different layout of the cylinder head.
[0016] At least three placement support rods 7 are fixedly installed on the top surface of the main beam 1 and the positioning beam 2. The top of the placement support rod 7 is provided with a support cap 8. When the present invention is not in use, the main beam 1 can be flipped over and the present invention can be supported and placed by the at least three placement support rods 7 without affecting the dial gauge 6.
[0017] The main beam 1 has handles 9 fixed laterally on both sides along its length. When measuring, the quality inspection tool can be moved by holding the handles, which is convenient to use.
[0018] The top of the X positioning head 4 is movably installed in the vertical through hole provided on the positioning beam 2 and is fixed with side bolts. The top of the Y positioning head 5 is movably installed in the vertical through hole provided on the main beam 1 and is fixed with side bolts, so that the downward length of the X positioning head 4 and the Y positioning head 5 can be adjusted to match the depth of the side positioning surface of the workpiece.
[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model. The workpiece in the dotted line portion in the drawings is only for illustration, and the four holes in the combustion chamber are actually provided on the side wall of the combustion chamber, but are shown as perfect circles in the figures.
