Description

Technical Field

[0001] The utility model relates to the technical field of coated milling cutter fixtures, in particular to a quick locking fixture for coating milling cutter processing. Background Art

[0002] A coated milling cutter is a rotary cutter with one or more teeth used for milling, and during processing, it needs to be clamped and fixed by a fixing device to stabilize its position. After searching, the Chinese patent authorization number CN218983932U discloses a quick locking fixture for coated milling cutter processing, including a machine tool fixing seat, a base, a limit seat, a support plate, a clamping plate, a worm, a linkage screw, a worm wheel, and a positioning rod. The beneficial effect of the utility model is that the worm gear is meshed and linked by rotating the worm in the locking clamp, thereby driving the two linked screws on the left and right to rotate synchronously and in the same direction, thereby making the horizontal plates on both sides of the clamp synchronously threaded and linked, so that the two sides are evenly stressed and quickly slide up and down in the limit seat, thereby quickly clamping and locking the shank of the coated milling cutter between the limit seat and the clamp, and at the same time, after the coated milling cutter is clamped and locked by the self-locking structure of the worm, the worm will not be linked due to the rotation of the worm gear, thereby causing the linked screw to be locked, thereby preventing the coated milling cutter from loosening, and a positioning rod is fixed at the center of the semicircular notch at the bottom of the clamp in the locking clamp, so that the shank of the coated milling cutter can be quickly positioned and docked in the semicircular notch. However, the milling cutter is a cylindrical tool, and when clamping, even if the milling cutter can be clamped stably by two semicircular clamping devices, it is easy to make the milling cutter slightly rotate in the clamped position during processing, making the position of the milling cutter easily offset.
