ABSTRACT:
A simple method of measuring the height of burrs such as formed in the crimped clamping portion of a crimp-style terminal, without cutting the terminal off from a cable fastened thereto, and a simple, inexpensive burr height measuring head to be used in combination with a displacement measuring device available in the market. The burr height measuring head comprises a grip, a measuring bit having a knife-edged tip and formed integrally with the grip so as to project from one end of the grip, and holding means rotatably joined to the other end of the grip and fixedly joined to the movable measuring member of a displacement measuring device. In measuring the height of a burr, the burr height measuring head is positioned with the knife-edged tip of the measuring bit in parallel contact with the bottom side of the burr, the scale of the displacement measuring device is adjusted so that the zero scale mark thereof coincides with the pointer of the displacement measuring device, the burr height measuring head is turned so that the knife-edged tip of the measuring bit extends substantially perpendicularly to the edge of the burr, the burr height measuring head is positioned so that the knife-edge tip of the measuring bit is in contact with the edge of the burr. The displacement of the burr height measuring head corresponding to the height of the burr is indicated on the scale of the displacement measuring device.
