Claims

[Scope of utility model registration request]

The shaft part of the engine valve is held on an immovable holding stand facing in the longitudinal direction, movable in the axial direction but immovable in the direction perpendicular to the axis, and the piston rod of the extended first air cylinder is extended. , the engine valve is fixed in a predetermined position by pressing the umbrella part of the engine valve and bringing the tip of the shaft part into contact with a positioning device whose longitudinal position can be adjusted;
Then, on both sides of the engine valve head, the piston rods of a pair of second air cylinders coaxially facing each other are extended, and the pressure contact plates fixed to the tips of both piston rods are brought into pressure contact with the head of the first air cylinder.・Use a second measuring device to measure the difference in the amount of expansion and contraction of the first and second air cylinders when the engine valve is a standard product and when it is the product to be measured, and check the dimensional accuracy of the product to be measured. In this device, a V-shaped groove for placing an engine valve shaft is cut in the upper end face facing upward.
A swinging air cylinder is provided on the side of a holding base having a pair of rising pieces, with a piston rod that both stands up and faces in one direction, and that swings up and down using the base end as a fulcrum. , and the center of a rocking plate with its lower end as a fulcrum is pivotally mounted, and a pressure roller facing left and right is pivoted to the upper end of the rocking plate, and when the piston rod in the swinging air cylinder is extended, the pressure roller holds the piston rod. An engine valve holding device in an engine valve accuracy measuring device, in which the dimensions of each part are determined so as to press the shaft portion of the engine valve on the table from above.
