Embodiment Construction

[0008] The following structural drawings further describe the present invention: as Figure 1-2 As shown, the non-contact free positioning cylinder deformation measurement method is characterized in that: the cylinder deformation T-shaped fixture 2 is set on the cylinder 4, so that the upper part of the T-shaped fixture 2 rests on the edge of the cylinder 4, and the lower part goes deep into the cylinder. In cylinder 4, fixture 2 is put into the cylinder barrel 4 and pasted with elastic soft medium 3, the width of the medium is about 8-12 mm, and fixture 2 pasted with soft medium 3 is put into engine cylinder barrel 4, so that the inner wall of cylinder barrel 4 Position with the outer edge of the soft medium 3; after positioning, the probe 1 is directly clamped into the cylinder deformation fixture; after the probe 1 is clamped, the probe 1 is concentric with the cylinder 4 and then the measurement starts. Because the positioning of the cylinder itself is currently used, and ...

Abstract

The invention relates to a non-contact freely-locatable method for measuring the deformation of a cylinder, which is characterized in that: the specific measurement process comprises the following steps: a fixture for the deformation of the cylinder is sheathed on the cylinder so that the upper part of the T-shaped fixture is lapped at the edge of the cylinder and the lower part of the T-shaped fixed is extended into the cylinder and is jointed therewith; the fixture is filled into the end of the cylinder and is provided with an elastic soft medium; the fixture is put into the cylinder of an engine after being pasted with the soft medium so that the inner wall and the outer edge of the cylinder are located; after that, a measuring head is directly clamped in the fixture for the deformation of the cylinder; and after ensuring the measuring head is clamped, the measuring head and the cylinder are concentric so as to start to measure. The invention is convenient for free fixation, is not limited by the type of the engine and the length of the cylinder, can measure the cylinders of the any engines, and can save time, labor and great development cost.

Description

Technical field: [0001] The invention relates to a non-contact free positioning cylinder barrel deformation measurement method, which is applied in engine tests. Background technique: [0002] At present, every engine research and development institution and production plant directly uses the purchased engine cylinder deformation measuring instrument to install and clamp on the upper or lower side of the engine cylinder when measuring the deformation of the engine cylinder. The additional deformation caused by the clamping force will seriously affect the accuracy of the data, make the test data unreliable, and cause large test errors. In addition, it is directly installed in the engine cylinder, and the jaws of the cylinder deformation instrument are generally 40mm, which reduces the measurement range of the cylinder by 40mm, and the deformation of the cylinder within 40mm cannot be measured. At present, there are two types of portable cylinder deformers in the world, namel...
