CUTTER Russian patent published in 1995 - IPC

FIELD: metal working. SUBSTANCE: cutting plate with a hole is fixed in the groove of the cutter holder by means of a clamping pin and a press screw. An irregularly shaped surface designed for the interaction with the intermediate member made in the form of a cylinder with a recess forming boshes is located in the lower part of the clamping pin. The irregularly shaped surface on the clamping pin is formed by shears from two sides forming a rib and supporting face surfaces. In this case the recess of the intermediate member encompasses the pin rib, and the boshes interact with the supporting face surfaces. A catching whose axle is located in the same axial plane as the rib is made on the head of the clamping pin in order to interact with the front surface of the plate. EFFECT: simpler design. 4 dwg
