Technical Field

The invention belongs to the technical field of machining inverted cone teeth of a gear shaping machine, and relates to a mechanism and a method capable of quickly and accurately adjusting the turnover angle of a workbench of the gear shaping machine.

Background

Inverted cone teeth are used in many parts of automobile transmissions. When machining inverted bevel teeth with gear shaping, it is common to use a table mechanism that is rotatable through an angle. At present, the structure of a domestic rotation angle workbench is shown in figure 1, and a worm 1 ' is manually rotated in the whole process to drive a worm wheel 2 ' to rotate, so that the workbench and a base 3 ' rotate together for a certain angle. The structure and the angle adjusting method have the following defects:

the operation is troublesome; because the square head is manually rotated in the whole course during adjustment, when a large angle is met, the manual rotation operation is time-consuming and labor-consuming.

The adjustment precision is poor; the worm gear pair with the structure has small reduction ratio, cannot be finely adjusted when the angle is manually adjusted, and has poor angle precision. And the device needs to be adjusted and measured repeatedly, thereby wasting time and labor. If a worm gear pair with a large reduction ratio is adopted, the manual operation intensity is increased, the external dimension of the mechanism is increased, and even the bearing capacity of the teeth is reduced.

The operation is inconvenient; the square head is far away from an operator and is vertically arranged upwards, so that the requirements of human engineering are not met.
