Abstract

828,551. Broaching. DETROIT BROACH & MACHINE CO. Jan. 2, 1957 [Jan. 3, 1956], No. 157/57. Class 83 (3). A machine-tool comprises a work-holder having a member 27 movable with the holder over a predetermined path to actuate a clamping-device 21, 22, on the holder, means 32 positioned along the path to move the member to operative position, and means 50 further along the path to stop the holder if the clamping- device has not been correctly actuated. Several holders are carried by chains 17 past broaching tools 12, which operate on the top or side of the workpieces W. The work-holders each consist of a fixed jaw 21 and a jaw 22 moved to clamping position by a wedge-bar 27 moved longitudinally by a striking-cam 32. The cam is pivoted on a pin 33, and is urged towards the path of the holders by a spring housed in a casing 35 having means for adjusting the spring tension. As the holder progresses past the cam, the bar is pushed inwardly until the edge slips past a recess 43 in the cam, and receives a final clamping blow. If the bar 27 is not moved inwardly for any reason and merely pushes aside the cam 32, it engages a plunger 50, which actuates a switch to brake and stop a motor driving the chains 17. A cam 54 at the exitend of the machine abuts and releases the wedge bars 27.
