| 摘要 |
A stop device that can be readily interconnected with a variety of commercially available vertical milling machines to precisely control the vertical travel of the quill mechanism of the milling machine. The bolt-on stop device of the invention includes three vertically adjustable stop mechanisms, each of which includes adjustable slide elements that can be horizontally extended or retracted relative to the quill mehanism of the milling machine. When extended the slide element moves directly into the path of vertical travel of a follower member, or depth indicator, provided on the quill mechanism of the machine. When retracted, the slide will clear the follower member of the quill mechanism so as to enable its engagement with the next adjacent stop or slide element of the device.
