The measuring range of the dial indicator refers to the maximum movement of the measuring rod, yes. A 3 mm,. One 5 mm, 0 ~ 10 mm three specifications.
Ordinary machine tool lever dial indicator structure
The lever-type dial indicator is small and flexible, and is often used in lathes and grinders to correct the installation position of workpieces, or in places where ordinary dial indicators are inconvenient. The structure principle of the lever dial indicator. The contact 1 is connected with the sector tooth plate 2 by the plate 11. When the contact swings up or down, the collapsing tooth plate drives the pinion 3 to rotate, and the end gear 4 coaxial with the pinion 3 also rotates accordingly, thereby Drive pinion 5. When the pinion 5 rotates, the coaxial pointer 6 also rotates, and the reading can be read on the dial. Rotate the bezel 7． The relative position of the dial scale and the hands can be adjusted. Since the contact between the contact 1 and the plate" is only connected by friction, the contact can swing from top to bottom or from bottom to top. This makes it possible to place the contact in any position when measuring surfaces that are difficult to access. When it is necessary to change the direction of the contact, just swing the wrench 8 on the side of the watch case, through the steel wire 9 and the stop pin 10, the sector tooth plate can be biased to the bottom or the top, so that the contact is in the desired position. direction.
