Abstract

Disclosed is an ACT quick cutter changing device. The ACT quick cutter changing device comprises a cutter disc body, a main shaft and a stand column, and is characterized in that the cutter disc body and the stand column are fixed; a plurality of first cutter clamping mechanisms are arranged at the edge of the cutter disc body at equal intervals; cutters are mounted on the inner sides of the first cutter clamping mechanisms through clamping mechanisms; pulleys are disposed at the edges of the first cutter clamping mechanisms; the main shaft is located inside the cutter disc body; a second cutter clamping mechanism is mounted on the lower portion of the main shaft; the top of the main shaft is connected with a cutter hitting cylinder; the cutter hitting cylinder is connected with the stand column through a first sliding way. The ACT quick cutter changing device has the beneficial effects that the main shaft is driven to move up and down in the axis direction so that the cutters can be clamped and reset; when another cutter needs to be used, the cutter disc body rotates, the cutter to be used rotates to the position below the main shaft, and cutter changing time is greatly shortened; besides, cutter changing accuracy is increased, and errors of cutter positions and main shaft cutter clamping positions are reduced.

Summary of the invention
The invention provides a kind of ACT tool changing device, be intended to the tool-changing speed and the precision that improve lathe tool magazine.
In order to solve the problem, a kind of ACT tool changing device provided by the invention, its technical scheme is as follows:
A kind of ACT tool changing device, comprise cutterhead body, main shaft, column, it is characterized in that: described cutterhead body and column are fixed, described cutterhead body edge is equally spaced is provided with multiple first swaging clamp mechanism, by clamping body, cutter is installed in the first described swaging clamp mechanism, swaging clamp mechanism edge is provided with pulley, described main shaft is positioned at the inside of cutterhead body, described main shaft bottom is provided with the second swaging clamp structure, the top of described main shaft is connected with knife striking cylinder, and described knife striking cylinder is connected with column by the first slide rail.
Preferably, for hollow is arranged in described knife striking cylinder, comprise locking device, track and cylinder, described locking device is connected on cylinder by track.
Preferably, the track of described track is not straight, connects two sections of straight rails form by one section of curved rail.
Preferably, described swaging clamp mechanism is connected with cutterhead body by spring.
Beneficial effect of the present invention is: by drive shaft moving up and down at axis direction, complete the clamping of cutter and the reset of cutter simultaneously, when needing to use different cutters, cutterhead body rotates, cutter to be used turns to below main shaft, shorten the time of tool changing greatly, and improve the precision of tool changing, decrease the error of tool position and main shaft swaging clamp position.

Detailed description of the invention
Below in conjunction with specific embodiment, invention is described further.
A kind of ACT tool changing device of embodiment
See Fig. 1, Fig. 2 (a), Fig. 2 (b), Fig. 2 (c), Fig. 3, the invention provides a kind of ACT tool changing device, it comprises cutterhead body 1, main shaft 2, column 3, it is characterized in that: described cutterhead body 1 is fixed with column 3, described cutterhead body 1 edge is equally spaced is provided with multiple first swaging clamp mechanism 120, by clamping body, cutter 130 is installed inside the first described swaging clamp mechanism 120, first swaging clamp mechanism 120 edge is provided with pulley 121, described main shaft 2 is positioned at the inside of cutterhead body, described main shaft 2 bottom is provided with the second swaging clamp structure 210, the top of described main shaft 2 is connected with knife striking cylinder 220, described knife striking cylinder 220 is connected with column 3 by the first slide rail 221.
Preferably, for hollow is arranged in described knife striking cylinder 220, comprise locking device 222, track 223 and cylinder 224, described locking device 222 is connected on cylinder 224 by track 223.
Preferably, described track 223 is not straight, connects two sections of straight rails form by one section of curved rail.
Preferably, the first described swaging clamp mechanism 120 is connected with cutterhead body 1 by spring 110.
Operation principle of the present invention is:
When needing tool changing, cutterhead body 1 rotates, stop at immediately below main shaft 2 to required cutter, the angle that cutterhead body 1 rotates when rotating each time is identical, then the cylinder 224 of knife striking cylinder 220 drives locking device 222 to move downward (micromotion is shown in that Fig. 3 from right to left) along track 223, main shaft 2 is driven to move downward, after main shaft 2 contacts with the first swaging clamp mechanism 120, second swaging clamp mechanism 210 of main shaft 2 lower end starts working, cutter 130 departs from from the first swaging clamp mechanism 120, be fixed in the second swaging clamp mechanism 210 of main shaft 2, main shaft 2 continues to move downward, first swaging clamp mechanism 120 changes at the relative position with cutterhead body 1, pulley 121 prevents the first swaging clamp mechanism 120 from scratching main shaft 2.After machining, main shaft 2 reposition (micromotion is shown in that Fig. 3 from left to right), first swaging clamp mechanism 120 sets back under the effect of spring 110, when the first swaging clamp mechanism 120 is with main shaft 2 flat contact, second swaging clamp mechanism 210 of main shaft 2 removes fixing cutter 130, first swaging clamp mechanism is fixed cutter 130, and main shaft 2 sets back under the effect of knife striking cylinder 220, completes a tool changing action.
Beneficial effect of the present invention is: by drive shaft moving up and down at axis direction, complete the clamping of cutter and the reset of cutter simultaneously, when needing to use different cutters, cutterhead body rotates, cutter to be used turns to below main shaft, shorten the time of tool changing greatly, and improve the precision of tool changing, decrease the error of tool position and main shaft swaging clamp position.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
