IPC: G01B3/22
Filed: 1985-04-30
Abstract: PURPOSE:To omit milling and facing working by utilizing press working and to reduce the cost of manufacture by using an inexpensive raw material for a main plate. CONSTITUTION:A circular blank conforming with the external diameter of the internal frame of a gauge is formed of the main plate raw material by press forming. Then, the peripheral edge part 11 of the blank is pushed down with a press to form a step connecting with the center part 12 of the blank. At this time, installation plates 13 and 15 for a key 2 for external frame setting and a spring 4 for external frame setting are left at the same plane positions with the center part 12 without being pressed down. Then, a through slot 6 for a stopping screw is bored at the peripheral edge part 11 and a hole 7 where the shaft of a gear, etc., is run is formed at the center part 12. Thus, the main plate is formed by press working, so milling is not necessary and the head of the screw running through the slot 6 need not be faced because of the step between the peripheral edge part 11 and center part 12. Then, a plate member made of brass which is easily pressed and inexpensive is usable as the main plate raw material.
