Abstract

The invention discloses a clamping tool for a cylinder-type workpiece. When the clamping tool for the cylinder-type workpiece is worked, the cylinder-type workpiece is embedded in a center hole of a tensioning sleeve. When an adjustable bolt is tightened, a piston compresses liquid plastics. The expansion of the liquid plastics forces the inner hole to expand inwards so that the workpiece is clamped. The clamping tool for the cylinder-type workpiece has the advantages of being strong in clamping force and good in centering effects.

Description

technical field [0001] The invention relates to a clamping tool, which belongs to the clamping technology of machine tools, in particular to a cylindrical workpiece clamping tool. Background technique [0002] At present, most of the fixtures commonly used to clamp cylindrical workpieces are centering chucks. Although centering chucks have the advantage of good versatility, they are usually clamped from both ends of the workpiece when clamping the workpiece. Longer workpieces are likely to cause eccentricity and affect the processing quality of the workpiece. There is currently no better solution to this. Contents of the invention [0003] The present invention aims at the defect existing in the existing centering chuck, which is easy to cause eccentricity and affect the processing quality of the workpiece when clamping a long workpiece. The present invention provides a cylindrical workpiece clamping tool. The type workpiece clamping tool has the advanta...
