Double-sided milling-machine cutter-fixing device

Abstract

The invention discloses a double-sided milling-machine cutter-fixing device, which comprises a square ram, wherein a cutter-fixing rod which can extend and shrink along the horizontal direction of the ram is arranged in the square ram; a milling cutter is arranged on the cutter-fixing rod; and the outer end of the square ram is provided with a buffering boss. In the double-sided milling-machine cutter-fixing device, when a circular arc at the root of a roll shaft neck is milled by a double-sided milling machine and the shaft neck of a machined roll is longer, milling is carried out according to a normal machining mode; and when the shaft neck of the machined roll is shorter, after the roll is clamped by a double-sided milling-machine clamp, the cutter-fixing rod in the square ram can extend out in the milling process, so that the occurrence of the collision and the interference of the horizontal moving direction of the square ram and the outer side of the clamp is avoided, and the machining can be normally finished. The double-sided milling-machine cutter-fixing device disclosed by the invention has a simple structure and is convenient to use, so that various rolls can be machined by the double-sided milling machine, and the machining range of the double-sided milling machine is enlarged.

Description

technical field [0001] The invention relates to a double-sided milling machine, in particular to a tool fixing device for a double-sided milling machine, and belongs to the technical field of milling machine components. Background technique [0002] The double-sided milling machine has the advantages of high efficiency, high precision, and good processing quality, and plays an important role in roll processing. as attached figure 1 As shown, when the double-sided milling machine is milling the arc at the root of the journal of the roll, because the journal of some rolls 1 is short, when the roll 1 is clamped by the fixture 2 of the double-sided milling machine, the space occupied by the fixture 2 is relatively large. During the process, the horizontal movement direction of the square ram 3 will collide with the outside of the fixture 2, resulting in failure to process. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the...
