Abstract

Forces, as illustrated in Fig. 1 and Fig. 2, exerted on the follower of a dial indicator will generally not harm the dial indicator, however, a force illustrated as in Fig. 3 will cause the dial indicator follower to deflect and bind within the housing of the dial indicator follower support.

Device for Applying Radial Force to Tool or Work Piece

Forces, as illustrated in Fig. 1 and Fig. 2, exerted on the follower of a dial indicator will generally not harm the dial indicator, however, a force illustrated as in Fig. 3 will cause the dial indicator follower to deflect and bind within the housing of the dial indicator follower support.

To overcome this difficulty, a retaining collar 10 is mounted do dial indicator follower support 12. The retaining collar 10 contains a cylindrical central opening 14, in which the dial indicator follower 16 is coaxially mounted. Engagement ball 18 is retained by retaining lips 20 of retaining collar 10. In this manner, the ball 18 is allowed to move within the retaining collar 10 but not become dislodged therefrom. Any force as indicated by the two arrows in Fig. 4, can be exerted and any translational movement of ball 18 will result in an exact duplication of that translation in follower 16, but any force exerted on dial indicator follower 16 will be the type of force illustrated in Fig. 1, and will not cause damage to the dial indicator follower shaft 12.
