CLAMPING UNIT HAVING HIGH DURABILITY

摘要

PURPOSE: A tool clamping unit with high durability is provided to improve the durability of a clamping unit which is worn away by impact friction by reducing pressure transmitted to each contact point into half. CONSTITUTION: A tool clamping unit with high durability comprises a gripper(1). Power is dispersed so that the conical oblique plane of a radial inner head portion(1a) and the conical oblique plane of a tail portion(1b) generate clamping force. Inclines reduce abrasion by dispersing the power.
