我厂自制车床时,因批量大,加工齿轮倒角发生了困难。老师傅们发扬自力更生精神,设计制造了一种齿轮倒角工具。此工具安装于滚齿机上,使一台滚齿机既能滚切齿型,又能进行齿轮倒角,并具有与齿轮倒角机相同的生产率和加工质量,制造成本也较低。齿轮倒角工具结构如图1所示,连接座6(图3)靠螺栓13将齿轮倒角工具固定在滚齿机刀具托架滑动导轨上。其一端装有电动机,并通过三角皮带轮18、28带动刀具26旋转(电机转速为2790转/分,皮带轮减速比为1.73);另一端有一燕尾导轨,其上装有能带动刀具沿工件轴心线上下移动的活动架10(图4),活动架10左侧的方槽与轴承座30左侧的方槽要装配后再一起加工。在方槽内装有活动座5。铜质的活动块4为半圆形凸块,与活动座5的半圆槽相配(图1
I plant self-made lathe, due to bulk, processing gear chamfering difficulties. Old masters who carry forward the spirit of self-reliance, design and manufacture of a gear chamfering tools. The tool is mounted on a gear hobbing machine so that a hobbing machine can be hobbed and chamfered with the same productivity and processing quality as a gear chamfering machine with lower manufacturing costs. Gear chamfering tool structure shown in Figure 1, the connector 6 (Figure 3) by the bolt 13 gear chamfering tool fixed to the gear hobbing tool holder sliding rail. One end of which is equipped with a motor and driven by a V-belt pulley 18,28 knife 26 rotation (motor speed of 2790 rev / min, the pulley reduction ratio of 1.73); the other end of a dovetail guide rail, which is equipped with a tool that can drive the workpiece along the axis Move the movable frame 10 up and down (Fig. 4). The left square groove of the movable frame 10 and the square groove on the left side of the bearing seat 30 should be assembled before processing together. In the square slot with a movable seat 5. The copper movable block 4 is a semi-circular convex block, which matches with the semi-circular slot of the movable seat 5 (FIG. 1)
