Detailed description of the invention
Below in conjunction with the accompanying drawings the invention is described in further detail.The invention is a kind of disc tool magazine for horizontal Machining centers, has tool magazine body, the cutter conveyer coordinated with tool magazine body, and cutter-exchange mechanism.
As shown in figures 1 and 3, the tool magazine body concrete structure of the invention is: have a disk 1 to be arranged on fixed support I 5, disk 1 can be rotated around its center by rotary shaft, disk 1 edge is provided with several cutter holder 2, each cutter holder 2 is each parallel to the axis of disk 1 and uniform along the edge of disk 1.The axis of the part of holding knife position of cutter holder 2 is parallel with the card of disk 1, after ensureing that cutter 3 is installed on cutter holder 2, cutter 3 axis is parallel to the card of disk 1, cutter 3 is arranged on disk 1 by the part of holding knife position on cutter holder 2, and the point of a knife of cutter 3 points to the center of circle of disk 1, owing to cutter 3 axis is parallel with the card of disk, therefore the width of tool magazine body is not limited by cutter 3 length, can compress further;Disk 1 is driven by servomotor I 4 and rotates, and controls the anglec of rotation of disk 1, makes the cutter 3 specified rotate to the position specified.Tool magazine body is attached to horizontal Machining centers lathe bed side by fixed support I 5 by screw, and the axis of disk 1 is parallel with horizontal Machining centers X-axis.
Also there is shown in Fig. 2 and Fig. 4 cutter conveyer be arranged on fixed support II18, there is servomotor II6, servomotor II6 is fixed on the top of fixed support II18 upper support frame I 15 by screw, line slideway I 16 is installed below bracing frame I 15, slide plate 17 is arranged in the slider I of line slideway I 16, equipped with ball-screw 10 on slide plate 17, one end of ball-screw 10 is equipped with Toothed belt pulley II9, the synchronous pulley I 7 installed with servomotor II6 axle head transmits moment of torsion by Timing Belt 8, servomotor II6 passes through Timing Belt 8 swing roller leading screw 10, thus drive slide plate 17 to prolong axis direction (i.e. the X-direction of the machining center) motion of disk 1, ensure that cutter 3 is transported to tool changing point;The lower surface of slide plate 17 is provided with line slideway II11, broach shell seat 12 is arranged on the slide block II of line slideway II11, cylinder 19 it is also equipped with below slide plate 17, for driving broach shell seat 12 prolong parallel with disk 1 card and point to direction, disk 1 center of circle (i.e. machining center Z-direction) motion, it is achieved broach shell advances and grabs the action of cutter;Being also equipped with rotary cylinder 13 on broach shell seat 12, broach shell 14 is installed on rotary cylinder 13, it is achieved 90 degree of rotations of broach shell 14, and broach shell 14 is rotated by machining center Z-direction machining center Y direction, and broach shell 14, when Y direction is downward, waits manual upper slitter.This cutter conveyer can realize the independence in three directions and drive: one is parallel with disk 1 and point to direction, disk 1 center of circle (i.e. the Z-direction of machining center) and driven by cylinder 19;Two, the axis direction (i.e. the X-direction of machining center) of disk 1 is driven by servomotor II6;Three, the Z-direction of machining center and Y direction 90 degree rotation, driven by rotary cylinder 13.
The most also there is cutter-exchange mechanism particularly as follows: cutter-exchange mechanism and cutter conveyer are separately fixed on bracing frame II23 and the bracing frame I 15 of both sides on same fixed support II18, both cooperate, this cutter-exchange mechanism includes servomotor III20 and the cam mechanism 21 being fixed on bracing frame II23, has the mechanical hand 22 that cam mechanism 21 controls.Carry out rising-rotate-tool changing action that falls by servomotor III20 driving cam means 21 driving mechanical hands 22, it is achieved Tool changeover.Cutter-exchange mechanism and cutter conveyer are arranged on the side of horizontal machining center machine, with tool magazine body homonymy.
Owing to each axle independently drives, preliminary election cutter function can be realized, shorten tool change time.
Work process: starting servomotor I 4, the disk 1 of tool magazine body is rotated around self center of circle by rotary shaft, servomotor I 4 controls the anglec of rotation of disk 1, makes cutter 3 rotate to specify position.Starting cutter conveyer, cylinder 19 drives broach shell seat 12 prolong parallel with disk 1 and point to direction, disk 1 center of circle (i.e. machining center Z-direction) motion, it is achieved broach shell advances and captures the action of cutter;Moved along the axis direction (i.e. machining center X-direction) of disk 1 by the lower broach shell 14 driving slide plate and slide plate 17 to connect that drives of servomotor II6 again, cutter 3 is made to be transported to tool changing point, start servomotor III20 driving cam means 21 driving mechanical hands 22 to carry out rising the tool changing action that rotation falls, realize changing to cutter 3 in broach shell 14.Realizing 90 degree of rotations of broach shell 14 under the driving of rotary cylinder 13, broach shell 14 to 90 degree of rotations of Y direction, is waited manual installation cutter by machining center Z-direction.
The invention has the feature of compact conformation, is particularly suited for into the machining center of line, and meanwhile, each axle independently drives, and can realize preliminary election cutter function, shortens tool change time.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all within the invention spirit and principle, any amendment made, equivalent, improvement etc., within should be included in the protection domain of the invention.
