Background
In turning, the vast majority of clamping products are clamped by three claws, based on the principle that the centers of circles are determined by three points, the three claws are automatically centered and clamped by clamping the outer circle of a blank, the efficiency is high, and the positioning is accurate. But not all the blank clamping surfaces of the parts are cylindrical, and some parts are in square geometrical structures. Whereas the square geometry part is adjusted to correct the clamping by four jaws as shown in figure 1. The four-claw adjustment and correction consumes a long time, and meanwhile, a line marking process needs to be added in front of the vehicle, so that the line pressing correction by a lather is facilitated. The four-jaw alignment needs four chuck jaws to be aligned one by one and repeatedly for several times, so that the clamping time is long, the alignment can be performed only by observing a marked line through naked eyes, and the alignment precision is not high. For parts with large batch and high machining precision requirements, the four-jaw chuck lathe machining square parts not only affects the production efficiency and increases the production cost, but also has correction errors in adjustment and correction, and affects the quality of products.
