Abstract
The invention discloses a novel clamp. Due to the fact that the three-point automatic centering mode is adopted, a large gap is reserved between the outer circle of the shaft segment, to be inserted into a part (8) to be machined, of a positioning base (3) and the inner circle of the part (8) to be machined; in this way, part installation and detachment can be achieved through a mechanical arm instead of manual work under the condition that the mechanical arm does not have high positioning precision, so that the purpose of replacing manual work with the mechanical arm is realized and the increase of investment caused by high requirement for the positioning precision of the mechanical arm is avoided. Therefore, labor cost can be greatly saved for an enterprise, and the competitiveness of products of the enterprise is improved greatly.
