Abstract

The invention relates to a centrifugal ball clamping fixture comprising an expanding sleeve type mandrel. One end of the coupling mandrel is connected to a housing, the coupling mandrel is provided with a first cavity fulfilled with steel balls, one end of the first cavity, at the connecting position with the housing, is provided with a limit step inside, and the other end of the expanding sleeve type mandrel seals the first cavity through a movably-connected moving part; the housing is provided with a second cavity inside; the first cavity and the second cavity are connected through a first ball, and the first ball and the limit step form a partitioning wall partitioning the first cavity and the second cavity; the second cavity is provided with an automatic extruding device used for extruding the first ball to move in a reciprocating manner. The centrifugal ball clamping fixture has the advantages that the fixture is simple in structure and convenient to use and is capable of clamping thin-wall cylindrical workpieces rapidly and tightly.

Description

technical field [0001] The invention relates to the technical field of tooling, in particular to a centrifugal force ball clamping fixture. Background technique [0002] The thin-walled cylinder is rolled from a thin steel plate, so the thin-walled cylinder is very easy to deform. The two ends of the thin-walled cylinder need to be machined. Since the thin-walled cylinder is a deformable part, the thin-walled cylinder cannot be directly clamped on the machine tool. This requires the design of special fixtures to solve the problem of deformation of the existing thin-walled cylinder. To sum up, there is no special tooling and fixture for thin-walled cylinders in machining, which leads to easy deformation of thin-walled cylinders. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a steel ball clamping fixture with simple structure and convenient use for quickly clamping thin-walled cylindrical workpieces.
