Main shaft handle rapid tool retracting unit

Abstract

The invention discloses a main shaft handle rapid tool retracting unit, and belongs to the machine tool retracting unit design technical field; the main shaft handle rapid tool retracting unit comprises a footstock, a push rod, a locking screw, a compact shaft, an inner hexagonal screw, an embossing handle, a compression spring, a support sleeve, a main shaft, a taper shank and a direction board; the top of the footstock is provided with a transverse through hole; the compact shaft is arranged in the through hole; the right end of the compact shaft is screwed with the embossing handle; the support sleeve is arranged below the footstock transverse through hole; the push rod is sleeved in the hole of the support sleeve; the embossing handle can be rotated to drive the push rod to move downwards; the taper shank arranged in the main shaft can be pushed to a proper position under the indication of the direction board, thus retracting the tool. The main shaft handle rapid tool retracting unit can smoothly dismount the tool without having tool retraction problems, is convenient in compaction, and the direction board on the right end of the embossing handle can accurately position the rotary amplitude of the embossing handle; the whole tool retracting motion is simple, and easy to realize.

Description

technical field [0001] The invention relates to the technical field of design of a tool return device for a machine tool, in particular to a quick tool return device for a spindle tool handle. Background technique [0002] With the development of the machinery industry, the requirements for the shape of the parts vary greatly, and the tools required for different shapes of workpieces are also different when they are processed on the machine tool. This requires frequent replacement of tools during the processing of the workpiece. Traditional tool clamping Most of them use base, pressing blade, bolt and other structures. It is troublesome to disassemble the tool, it is difficult to realize the retracting action, and it is inconvenient to press. The size of the pressing force mainly depends on the experience of the workers and is not accurate enough. It is necessary to have an easy-to-implement and compact device for the fast retraction of the tool holder of the machine tool sp...
