Double-piston indexing milling head

Abstract

The invention belongs to the technical field of metal processing, and particularly relates to a double-piston indexing milling head which comprises a top seat, a fixed seat and a main shaft shell. Supporting frames are transversely arranged on the left side and the right side in the top seat; indexing upper fluted discs are installed at the bottoms of the supporting frames; movable seats are arranged at the bottoms of the left side and the right side in the top seat; indexing lower fluted discs matched with the indexing upper fluted discs are mounted at the tops of the movable seats; a rotating rod, a fixed column, a spring, a fixed block, a fluted disc seat, a limiting block, transposition lower fluted discs, moving blocks, a first piston mechanism, a second piston mechanism and transmission rods are sequentially arranged in the fixed seat from inside to outside; the transposition lower fluted discs are arranged on the tops of the left side and the right side of the fluted disc seat;transposition upper fluted discs matched with the transposition lower fluted discs are installed at the bottom of the movable seats; first movable grooves are longitudinally formed in the left side and the right side of the fixed seat; and the indexing fluted discs and the transposition fluted discs can be reliably clamped through a double-piston structure, so that rotation driving of a main shaftis guaranteed to be more stable, and the situation of unstable eccentric-load guiding is improved in a limited mode.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a dual-piston indexing milling head. Background technique [0002] The milling head part of a milling machine or machining center is the final part to realize the cutting of the workpiece by the machine tool. The processing spindle of the existing milling head is generally a single form of horizontal or vertical. The milling head often needs to be equipped with an indexing mechanism to adjust the angle of the spindle. Adjustment, so as to realize multi-faceted processing, the existing milling head parts are often single-piston design, the pre-biased load guide is unstable, and the clamping and fixing of the indexing toothed disc and the indexing toothed disc is not stable enough, which affects the rotation of the spindle. stability. Contents of the invention [0003] The purpose of the present invention is to provide a dual-piston indexing milling head to solve the pr...
