Embodiment Construction

[0024] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0025] attached Figure 1-3 It can be seen that a gear tooth bottom forming milling cutter includes a milling cutter body 1 and a cemented carbide blade, and the cutter body 1 is composed of several cemented carbide blades and fixing screws; the cutting position of the cutter body 1 is provided with a chip groove and cemented carbide blade assembly groove; cutter body 1 is provided with assembly shaft hole, radial positioning keyway, wheel hub 2 and fixed blade bolt hole; cemented carbide blade is fixed on the groove of cutter body by screws, and the blade is While finishing the bottom 12, the involute profile 13 of the tooth shape is rough cut; the top of the cutter body is provided with a top blade 10; the two sides of the cutter body are provided with side blades 6; The top blade 10 is provided with a straight cutting edge and an arc cutting edge; the arc cutt...

Abstract

The invention relates to a gear tooth bottom forming milling cutter, which comprises a milling cutter body and a carbide blade, wherein a chip groove and a carbide blade assembling groove are arranged in the cutting position of the cutter body; an assembling axle hole, a radial positioning key groove, a hub, a chip flute, a blade assembling groove and a fixed blade bolt hole are arranged in the cutter body; and the carbide blade is fixedly arranged on a cutter-body groove through screws. The blade completes finish machining for a tooth bottom and carries out rough cutting machining for the involute profile of a tooth form at the same time. The gear tooth bottom forming milling cutter can decrease the tooth form cutting machining procedure, increase the cutting machining speed, reduce the cutting resistance of finish-milling teeth and finish-hobbing teeth, and increase the production efficiency. The gear tooth bottom forming milling cutter particularly increases the machining speed of the machining procedure of the finish-hobbing teeth and the finish-milling teeth of a gear and ensures that the machined gear has the stable and ideal precision and quality.

Description

technical field [0001] The invention relates to a gear machining tool, in particular to a gear tooth bottom forming milling cutter. Background technique [0002] At present, gear milling and hobbing with a large modulus use formed tools to cut the full tooth profile. The tool shape design and processing concept follow the cutting process of peeling the full tooth profile layer by layer in each process. Its cutting resistance changes with the amount of cutting and the change of feed speed, and the surface quality of the tooth surface contour also changes with the change of feeding speed of the cutting amount, and cannot be changed according to the precision requirements of the tooth surface on the working state of the tooth surface . In particular, the fine milling and hobbing of gears are particularly prominent, which limits the efficiency of gear processing and makes gear processing unable to reduce processing costs. Contents of the invention [0003] Aiming at the defi...
