Abstract

By designing a ball socket with its ball center located at the part- clamping surface, stresses in the element are eliminated due to the natural ability of the clamp surface to conform to the clamping surface. The arrangement consists of a type element clamping mechanism 10 which will not stress or distort the element when inspecting the character locations on the ball or type element 12. The most important characteristic stems from the ball-socket clamping mechanism 14 centerline being located precisely in-line with the clamping surface 16 of the type element 12. If the ball socket 14 were positioned back in the clamp mechanism 10, as shown in Fig. 4, a slipping action of the clamp 10 and the part-clamping surface 16 would result when clamped.

Non-Stressing Type Element Clamping Mechanism

By designing a ball socket with its ball center located at the part- clamping surface, stresses in the element are eliminated due to the natural ability of the clamp surface to conform to the clamping surface. The arrangement consists of a type element clamping mechanism 10 which will not stress or distort the element when inspecting the character locations on the ball or type element 12. The most important characteristic stems from the ball-socket clamping mechanism 14 centerline being located precisely in-line with the clamping surface 16 of the type element 12. If the ball socket 14 were positioned back in the clamp mechanism 10, as shown in Fig. 4, a slipping action of the clamp 10 and the part-clamping surface 16 would result when clamped. This is due to the swinging action at the clamp surface when trying to conform to the part clamping surface 16 which is not always parallel from one part to another. As part of the inspection procedure, the element 12 is rotated from one character row to another. Therefore, a thrust bearing 18 is incorporated for minimum torque and also to prevent the ball 12 from slipping on its locating surface 16. The ball socket diameter 24 is made to its maximum to provide as much surface area as possible for driving friction to insure rotation of the thrust bearing 18 and no slippage of the ball socket 14.
