Abstract

The invention discloses a high-precision elastic barrel clamp fixing device. The high-precision elastic barrel clamp fixing device comprises a first fixing piece, a locking piece fixed to the first fixing piece, a clamping piece and a plurality of rolling pieces. The clamping piece and the locking piece are matched and form a roller path. The multiple rolling pieces are contained in the roller path and make contact with the locking piece and the clamping piece. According to the high-precision elastic barrel clamp fixing device, through cooperation of the rolling pieces, the clamping piece and the locking piece, kinetic friction between the first fixing piece and a clamped elastic barrel clamp is avoided, the assembling precision is guaranteed, and the service life is prolonged.

Description

Technical field [0001] The invention relates to the technical field of machine tool assembly, in particular to a high-precision elastic collet fixing device. Background technique [0002] With the demand for economic development and technological take-off, more and more new technologies are emerging, and the machining industry is also emerging, especially the technological innovation in the leading spindle industry. As one of the core accessories of the high-speed electric spindle, the high-precision elastic collet fixing device has become a new bright spot in the development. With the requirements of various industries for machining efficiency and machining accuracy, machine tool processing is developing in the direction of large rough machining torque, strong shock resistance, fast finishing speed and high surface accuracy. The development direction of rough machining and finishing requires that the elastic collet used by the spindle must meet the requirements of large clampin...
