Abstract

The invention discloses a large turning angle positioning vacuum chuck which comprises a chuck base, a positioning ball, a turning block A, a turning block B, a bolt A, a sealing rubber cup, a bolt B, a sealing strip A and a sealing strip B. The chuck base is connected with the positioning ball, the turning block A and the turning block B are connected together by the bolt A, the inner surfaces thereof form a spherical surface which slide coordinately with the positioning ball. The turning block A and the turning block B are sealed by the sealing strip B, the turning block A, the turning block B and the positioning ball are spherically sealed by the sealing strip A. The sealing rubber cup is connected with the turning block A and the turning block B by the bolt B. The chuck adopts the positioning ball to carry out point positioning so as to ensure positioning accuracy, thereby realizing large angle turning of the chuck, being suitable for the process of sheet metal parts with different curvatures, enlarging the serviceable range of machine tools, solving the problem of numerous tooling during process of edge trimming of the sheet metal parts and the like, increasing the flexibility of tooling, and improving the production efficiency.

Description

Technical field:

[0001] The invention relates to a suction cup, in particular to a large-rotation-angle positioning vacuum suction cup, which belongs to the field of machining tools, in particular to a suction cup device used in the field of flexible support tooling with large-rotation angle and high-precision positioning requirements. Background technique:

[0002] Ensuring the processing precision of thin-walled parts mainly depends on two factors, one is high-precision machine tools, such as CNC milling, laser cutting machines, etc.; the other is fixtures. Among them, high-precision trimming machine tools are already available, and the fixtures need to be designed and manufactured. Among them, suction cup flexible tooling is an optimized choice. There are many types of thin plate structures, and the traditional method is to use special mold tires for support and fixation. The number of molds is large, the cost is high, and the preparation period is long. Therefore, the ...
