The embodiment is based on the method for measuring the full size of the valve seat of the intake valve seat ring of any gasoline engine, and provides an actual embodiment:
the cylinder cover 4 selected by the invention is a 4GA cylinder cover of a certain company, the inclination angle of the axis of the inlet valve guide pipe 10 hole of the cylinder cover is 19.5 degrees, and the inclination angle of the axis of the exhaust valve guide pipe hole is 22 degrees. By adopting the measuring method, the diameter of the position of the valve seat sealing ring of the intake and exhaust valve seat ring can be directly measured. The measurement process of the flexibility measurement method of the present invention is described in detail below by taking the intake valve seat ring and seat measurement as an example.
First, the cylinder head 4 is supported by four conical supports 6,7,8,9 with height adjustable, and the inclination angle of the cylinder head combustion chamber side plane (the contact surface of 3 and 4) is measured by the digital angle measuring instrument 3. Adjusting the side plane of the cylinder cover combustion chamber to be horizontal to the plane of the three-coordinate workbench by adjusting the height of the conical supporting screw rod;
secondly, the three-coordinate measuring probe 2 dispersedly collects 16 points on the plane of the cylinder cover combustion chamber side, the measuring probe is ensured to be vertical to the plane of the cylinder cover combustion chamber side when the points are collected, and the three-coordinate constructs the collected point characteristics into a plane, namely the actual plane of the cylinder cover combustion chamber side;
thirdly, because the inclination angle of the inlet valve guide hole axis 10 and the cylinder cover seat ring valve seat 5 is 19.5 degrees, the adjustable angle interval of the three-coordinate measuring needle seat 1 is 7.5 degrees. We choose to adjust the three coordinate stylus 2 to 22.5 deg. to the three coordinate table plane. In order to ensure that the three-coordinate measuring needle 2 is parallel to the axis of the inlet valve guide pipe hole 10, the cylinder cover 4 needs to be inclined to form an angle of 3 degrees with the three-coordinate workbench. The 3-degree adjustment is realized by heightening two conical supports 6 and 7 on the same side below the cylinder cover 4;
thirdly, the three-dimensional digital analogy of the cylinder cover is led into a three-coordinate measuring program, and the three-coordinate measuring needle 2 scans and collects point cloud data on the upper, middle and lower three sections of the hole 10 of the intake valve guide pipe in a scanning mode. The three-coordinate system constructs an axis, namely the actual axis of the intake valve guide 10, from the acquired point cloud characteristics. Constructing an intersection point of the axis of the hole of the intake valve guide pipe 10 and the side plane of the cylinder cover combustion chamber continuously in a three-coordinate measuring program;
and thirdly, calculating the distance between the intersection point of the axis of the valve guide pipe 10 and the side plane of the cylinder cover combustion chamber on the theoretical drawing and the theoretical sealing ring of the cylinder cover intake valve seat ring valve seat 5. The theoretical distance value is input in a program of the three-coordinate measuring machine, and a self motion control system of the three-coordinate measuring machine is adopted to enable a measuring head of a three-coordinate measuring needle to automatically move to a measuring position of a sealing ring of a valve seat ring 5 of a cylinder cover valve seat ring from a crossing point position constructed in the previous step. Collecting measured section data in a scanning mode, and calculating and evaluating the diameter and the roundness of an actual sealing ring in a data fitting mode of a maximum circumscribed circle;
and finally, in three-coordinate measurement evaluation software, the bounce of the seat ring and the valve seat is evaluated by taking the axis of the point cloud characteristic structure acquired by the intake valve guide 10 as a reference.
