Processing device

Abstract

The invention relates to a processing device. The processing device comprises a main shaft locating device, wherein the main shaft locating device is connected with an outer support body which is connected with a power transmission device, the power transmission device is connected with a cutter clamping device which is connected with a cuter, the cutter clamping device comprises a cutter mounting base, an outer sleeve and a locking screw, a radial hole and an axial cutter mounting hole are formed in the cutter mounting base, the radial hole of the cutter mounting base is formed by a straight hole section and a spherical hole section, the spherical hole section is directly communicated with the cutter mounting hole, a steel ball is arranged in the spherical hole section, the outer sleeve sleeves the cutter mounting base, a radial through hole is formed in the outer sleeve, the locking screw stretches into the radial hole of the cutter mounting base to be in threaded connection with the straight hole section of the radial hole after penetrating through the radial through hole of the outer sleeve, and the steel ball can be pressed in the spherical hole. According to the processing device, the assembling precision of the cutter can be improved, and the adverse effect on the cutter during processing can be reduced.

Description

technical field [0001] The invention relates to a processing device. Background technique [0002] The milling cutter of the traditional milling machine is clamped by a collet with a spring, and then tightened and locked by the lock nut. After long-term processing and use, the thread of the lock nut and the collet cooperates to produce a gap, and the nut cannot completely lock the collet. However, the clamping force produced by this structure on the tool is relatively small, so that the tool cannot be completely fixed on the collet, which affects the working stability of the tool. And the milling cutter completely relies on the clamping screw to lock the milling cutter inserted into the tool mounting seat, but because the feed rate of the screws distributed around the milling cutter cannot be completely equal, the axial deviation of the tool from the tool installation is caused. The axial direction of the center hole of the seat has an adverse effect on the milling cutter d...
