Embodiment Construction
[0022] Embodiment 1 of the present invention provides a valve seat ring inspection tool, which is used to detect the seat ring 2 to be inspected placed on the flat plate 1, such as figure 1 with figure 2 As shown, it includes: a cylinder 4 with a mandrel 3 inside (the diameter of the seat ring gauge), the lower end of the cylinder 4 is in conflict with the flat plate 1, and the lower end of the mandrel 3 is in contact with the tested seat The ring 2 is in conflict, and the other end of the mandrel 3 is connected with the dial gauge 6 through the spring 5 . The bushing 7 is arranged between the cylinder 4 and the mandrel 3 . Among them, the cylinder and the embedded bushing act as a guide, so that the mandrel and the tested seat are coaxial.
[0023] Embodiment 2 of the present invention provides a valve seat ring detection method, such as image 3 shown, including the following steps:
[0024] Step 101, press the bottom end of the inspection tool against the flat plate, a...

The invention discloses a valve seat ring detection tool which is used for detecting seat rings to be detected and arranged on a flat plate. The valve seat ring detection tool comprises a barrel, wherein a mandrel is arranged in the barrel, the lower end of the barrel is contacted with the flat plate in butting mode, the lower end of the mandrel is contacted with the seat rings to be detected in butting mode, and the other end of the mandrel is connected with a dial indicator through a spring. The invention further discloses a valve seat ring detection method which includes the following steps that the seat rings to be detected are placed on the flat plate, the bottom end of the detection tool butts against the flat plate, and the mandrel overcomes elasticity of the spring, moves upwards and drives a pointer of the dial indicator to display the upward moving distance; the detection tool departs from the flat plate, and the seat rings are pushed out of the detection tool through the spring; and the above two steps are repeated, and gauge heights and sizes of all the seat rings are measured. The valve seat ring detection tool is simple to manufacture, can be used for measuring gauge heights and sizes of the seat rings conveniently, is low in detection cost and can completely achieve gradual detection.
Description
technical field [0001] The invention relates to a valve seat ring inspection tool and a detection method. Background technique [0002] The cylinder of diesel engine and gasoline engine is composed of cylinder block and cylinder head. Among them, the height dimension of the valve seat ring gauge is closely related to the working performance and quality of the cylinder. The height dimension of the valve seat ring gauge in the prior art is usually measured with a three-coordinate instrument, which cannot be measured one by one due to the limitation of the number of inspected, and the inspection cost is high, which needs to be improved urgently. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a valve seat inspection tool and detection method. Through the implementation of the present invention, the detection cost and complexity are reduced without being limited by the number of inspections...
