Embodiment Construction

[0027] 1. Specific implementation mode one: combining figure 1 , figure 2 , image 3 As shown, the present invention is a high-efficiency vertical milling cutter head and a special blade. The center of the top of the cutter head (6) is provided with a main fastening bolt hole (5) and a keyway (2). The disc (6) is fixedly installed on the power shaft; the secondary mounting hole group (1) is provided around the main fastening bolt hole (5), so that the cutter head can be better connected and fixed with the power shaft; it can avoid the cutting vibration caused by the cutting tool The disk (6) is loosely connected with the power rotating shaft, thereby improving the tool life.

[0028] 2. Specific implementation mode two: combining figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 As shown, a plurality of grooves (11) are arranged on the outer periphery of the cutterhead (6) in this embodiment, and locking screw holes (13) are ...

Abstract

The invention relates to a high-efficiency vertically-arranged milling cutterhead and special blades, and belongs to the technical field of cutters for metal cutting machining. A main fastening bolt hole is formed in the top of the cutterhead, the cutterhead is connected with a power transmission shaft through a bolt, the cutterhead is positioned through a key slot, so that the cutterhead can be well mounted and fixed on the main shaft, and machining vibration is reduced; a plurality of cutter grooves of vertically-arranged cutter clamps are uniformly formed in the periphery of the cutterhead,and the cutter clamps are locked in the cutter grooves through locking screws; and each cutter clamp is provided with a cutter holder for installing the special blades, the special blades are fixed in cutter holders through pressing screws, and the axial cutting depth of the special blade can be adjusted through eccentric adjusting pins. The special blades and the cutter clamps adopt a vertical installation mode, the operation is simple and convenient, the service life of a cutter can be prolonged, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a high-efficiency vertical milling cutterhead and a special blade, belonging to the technical field of metal cutting cutters. Background technique [0002] During the cutting process of key parts of large-scale equipment such as automobiles, airplanes, and nuclear power plants, due to the high hardness of the workpiece material, irregular structural shape, and defects in the machined surface, vibrations are likely to occur during cutting, which makes the compression of the fixed cutting tool The screw becomes loose, which in turn aggravates the vibration of the insert, and milling is an intermittent cutting, with frequent cyclic shock loads on the tip and edge of the tool, as well as rapid thermal-mechanical alternating loads, which can easily cause the tool to form thermal-mechanical stress in the cutting zone. Fatigue cracks lead to chipping of the blade and wear and damage of the cutting disc, which reduces the service life ...
