Abstract

The invention relates to the field of machining, and particularly discloses a thin-wall cylindrical part clamp which is characterized by comprising a supporting shaft, an annular base coaxial with the supporting shaft is arranged on the supporting shaft, a connecting ring coaxial with the annular base is fixed to the inner side of the annular base, and the connecting ring is fixedly connected with the supporting shaft. A plurality of main supporting blocks are distributed on the peripheral side of the annular base in a circular array mode, each main supporting block is an arc-shaped section, connecting rods are fixed to the inner surfaces of the arc-shaped sections and face the supporting shaft, the connecting rods penetrate through the annular base and are connected to the annular base in a sliding mode, and reset springs are arranged between the connecting rods and the annular base. A nut is in threaded connection with the supporting shaft, a circular-truncated-cone-shaped pushing block is fixed to the end of the nut, and the supporting shaft is sleeved with the pushing block. The invention aims to solve the problems that an existing thin-walled cylinder part clamp is prone to cause clamping deformation of a workpiece and reduce the precision.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, and specifically discloses a thin-walled cylinder fixture. Background technique [0002] Thin-walled cylindrical parts are often used by product designers due to their advantages of light weight, compact structure, and small footprint. However, the processing accuracy of thin-walled cylindrical parts is a thorny problem. The general processing technology of such parts is processed by lathe. The existing processing of thin-walled cylindrical parts generally adopts radial clamping with an elastic sleeve attached to the outer circle of the workpiece or clamping with a three-jaw chuck. This technology is likely to cause clamping deformation of the workpiece, lower precision, and low production efficiency. ; The second is one-piece shaft fixation, so that the workpiece is set on the shaft and fixed at both ends, and the middle is filled with rubber, paraffin and other media. Due to the h...
