Adjustable top

The column of the rocker drill of our factory is made of cast iron. Because the workpiece is long and heavy, the outer circle of the car needs to be machined with the top end of the inner hole. The inner holes of the castings are generally irregular. Therefore, the wall thickness of the rear pillars is not uniform, making it difficult to meet the processing requirements. To this end, we have designed an adjustable top. It consists of two fixed top teeth and one adjustable top tooth, which can not only play the role of turning the workpiece, but also adjust the adjustable top teeth with the change of the irregular inner hole, so that it is no longer in the outer circle of the car. Affected by the irregular shape of the inner hole.
