Problems solved by technology

[0002] For parts that need to be positioned by the inner hole of the blank, the internal structure is complex, the size of the blank is unstable, it is difficult to ensure the size of the part to be processed by ordinary three-jaw clamping, there may be deviations in the depth of the end face, and the ellipse of the inner hole is large, etc.
It is more convenient to make three claws in operation, and the cost is low, but the actual scrap rate is high, and the frequency of repair is more
When producing parts in large quantities, the cost of scrap products increases, the labor intensity of repair is high, and the quality of products cannot be controlled

Abstract

The invention relates to the technical field of adoption of blank holes for positioning of complex parts, in particular to a double-self-centering peripheral float clamping mechanism which is capable of conveniently realizing positioning stability, efficiency improvement and guarantee of product quality. The peripheral float clamping mechanism comprises a base, a mandrel middle seat is mounted on the base, the outer side of the mandrel middle seat is provided with an annular boss, a bolt is mounted in the mandrel middle seat, the lower end of the bolt is in threaded connection with a positioning mandrel, and two positioning devices sleeve the bolt. Each positioning device comprises a cylindrical compression spring, a bushing and movable positioning plates, wherein the cylindrical compression spring and the bushing sleeve the bolt, the movable positioning plates are connected with the mandrel middle seat through a top pressure spring, the cylindrical compression spring is arranged at the lower end of the bushing, the movable positioning plates are arranged at the upper end of the bushing, the lateral side of the upper end of the bushing is provided with an annular slope, and one end of each movable positioning plate is provided with a slope matched with the annular slope while the other end of each movable positioning plate penetrates through the mandrel middle seat.

Description

technical field [0001] The invention relates to the technical field of positioning complex parts by using blank inner holes, in particular to a double self-centering outer circle floating clamping mechanism. Background technique [0002] For parts that need to be positioned by the inner hole of the blank, the internal structure is complex, the size of the blank is unstable, and it is difficult to ensure the size of the part to be processed by ordinary three-jaw clamping. There may be deviations in the depth of the end surface, and the ellipse of the inner hole is large. It is more convenient to make three claws in operation, and the cost is low, but the actual scrap rate is high, and the frequency of repair is more. When parts are produced in large quantities, the cost of waste products increases, the labor intensity of repair is high, and the quality of products cannot be controlled. Contents of the invention [0003] In order to solve the above problems, the present inv...
