Locking a Manufacturing Adjustment in Place

An adjustment screw is locked in place by welding to it a small sphere located in a hole in a frame through which the screw is threaded.

A U-shaped frame 10 (seen from the top in the drawing) has an upstanding arm 11 carrying a threaded setscrew 12. Rotation of screw 12 moves face 13 in the direction 14 to provide an adjustable stop for the travel of a machine member (not shown). When screw 12 has been adjusted, welding electrodes 15 are placed against arm 11 and a small spherical ball or bearing 16 that has been inserted into hole 17. Then a 0.016 second or less low-voltage high ampere current is passed through arm 11, screw 12 and ball or bearing 16. An electrode follow-up force is applied, causing ball 16 to fuse to screw 12 and to the side of hole 17 in arm 11. This locks screw 12 firmly into position without applying excessive force to arm 11, which might destroy the setting by warping the arm.
