Crankshaft milling cutter structure

Abstract

The invention discloses a crankshaft milling cutter structure, which comprises a connecting handle, a connecting groove, a main shaft, a crank arm, a crank arm connecting shaft, a fixed plate, a connecting column, a gear, a ferrule, a groove, an operating handle, a shock absorber, a cutter Heads, teeth and drill bits. The beneficial effects of the present invention are: by setting the crankshaft arm on the device, the cutting speed of the milling cutter can be uniform when the milling cutter is working by cooperating with the main shaft and the crankshaft connecting arm, which can make the cutting out The surface smoothness of the workpiece is high. By arranging the fixed plate, in some cases where special high-speed processing is required, the cutter head will not rotate together with the crankshaft, and has its own rotation rate. By setting the shock absorber, the large vibration force brought to the milling cutter due to the excessive cutting speed can be reduced, and the slipping or tilting caused by the vibration force can be avoided. By setting the drill bit and pre-drilling the workpiece in advance, the processing difficulty of the milling cutter is reduced.

Description

technical field [0001] The invention relates to a crankshaft milling cutter, in particular to a crankshaft milling cutter structure, belonging to the field of milling cutter applications. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. When optimizing the milling effect, the blade of the milling cutter is another important factor. In any milling, if more than one blade participates in cutting at the same time, it is an advantage, but too many blades participating in cutting at the same time is a disadvantage. It is impossible for one cutting edge to cut at the same time. The required power is related to the number of cutting edges participating in the cutting. The position of the milling cutter...

Problems solved by technology

[0003] However, the existing crankshaft milling cutter structure still has certain defects in use. Although the existing crankshaft milling cutter structure can perform some simple processing of the workpiece, due to the high cutting speed during processing, it cannot be controlled, and the workpiece often appears The surface is not smooth, and the cutting speed is too high, which makes the vibration force of the milling cutter larger, and the phenomenon of slipping or tilting occurs, which brings inconvenience to the operator.
