The indexing head is a machine accessory that holds the workpiece with a chuck or with a top and dial and rotates it and divides it. If you do not understand the indexing of the indexing of the way, the following Xiaobian to introduce you to the indexing of the sub-way:
1, simple indexing method Simple sub-index method is also called single-type indexing method, he is the indexing plate fixed, indexing the handle relative to the dial to turn a certain number of revolutions, so that the workpiece through the required equal score Or degrees. This is the most commonly used method of indexing. The following are the same as the "
2, the angle of the degree of grading method is another method of the degree of sub-indexing method, but one is the workpiece equal score Z as a basis for calculation, one is the angle of the workpiece as an equal basis, Head gear ratio of 1:40, that is to say turn the handle turn, the workpiece only turn one quarter turn. The following are the same as the "
3, differential indexing method Differential indexing method is to split the head of the spindle and the exchange side of the wheel with the exchange of teeth to connect, that is, connected with the indexing plate, and release the indexing plate of the solid screws. So that when the indexing of the indexing of the handle, the actual number of revolutions of the handle will be equal to the relative degree of the handle relative to the degree of dial and the degree of rotation of the index plate to achieve the value can not be similar and sub-fragrance on the corresponding hole The The following are the same as the "
4, the linear distance from the degree of linear shift from the spindle exchange gear method and the side of the exchange gear method of two sub-degree method. He is the use of exchange gear so that the dividing head spindle and longitudinal table screw connection, turn the indexing handle, and the empty can make the table for accurate movement.
