Description

Tool magazine

The invention relates to a kind of tool magazine, more particularly, is the tool magazine that is used on milling machine and the drilling machine, and it comprises a horizontal tool head, and this knife rest has row's blade clamping apparatus and swings on workbench.

A kind of tool magazine in this type is known (" KIWA " Maxzenter MM brochure), and wherein, a kind of knife rest with row's blade clamping apparatus is mounted in the stand, and this stand is together moved with workbench.To a side, knife rest can be swung according to the longitudinal axis of stand from a kind of inactive state, thereby its blade clamping apparatus is taken on the cutter changing position of headstock front.Yet on the resting position of the side of work package knife rest, this knife rest has occupied a sizable space, thereby has reduced the free lateral region of the work that is directly used in process.In addition, if the work package that clamps is bigger, just can not carry out cutter changing, this is owing to can bump with workpiece at knife rest pendulum cutter when changing state.

The objective of the invention is to provide a kind of tool magazine, more specifically say so and be used for the tool magazine of milling machine and drilling machine, utilize this tool magazine, can change level and vertical milling head, and need not distinguish more changing device, even also be so under the bigger situation of clamping work, also can not occupy the free space that is directly used in workpiece in addition.

According to the present invention, this purpose can reach through the following steps, and knife rest hingedly is installed in the end of at least one swing arm, and this swing arm is hinged on the workbench, and it can be swung according to a horizontal axis like this.

The mode that knife rest is installed on the workbench according to the present invention provides this useful possibility: when knife rest time spent not, knife rest together can be gone to workbench one side together with cutter or the front is lower than on the level of workbench, like this, just, can not occupy the free space all around of the work of being directly used in.Favourable situation is can select swing arm and its anglec of rotation like this, so that the replacing of cutter can be carried out outside the space of any clamping work package.

A preferred embodiment of the present invention is characterized in that: knife rest is fixing by its two ends, and each end is installed in the swing arm, and swing arm is to be hinged on two sidewalls of workbench, so that swing around a common trunnion axis.Like this, this knife rest constitutes the arc framework of U word with two swing arms, this framework can be changed the position pendulum from top to a resting position, this position is in the diagonal below of workbench front end arm, here, knife rest is loaded in the toolbox together with the cutter that is fixed on its blade clamping apparatus, and this toolbox can cut out with an end baffle, like this, just, can prevent because the pollution of stream of drill cuttings, metal fillings and thing like that.

Like this, when knife rest pendulum time-out, cutter can form straight line with headstock feathering axis or vertical rotating shaft, knife rest can utilize a motor to swing with respect to the swing arm end according to a horizontal axis, like this can be with the axis levelling of corresponding tool axis and feathering axis or vertical rotating shaft.For this reason, except that the swing of knife rest, also need on three axis directions, carry out laterally moving of workbench and moving of corresponding cutters rotating shaft, after alignment, utilize rotating shaft along the level of its longitudinal axis or move both vertically provide once feed action, finish actual cutter changing.

In the cutter changing process of feathering axis, bump for fear of rotating shaft and/or workpiece and contiguous cutter, preferably tool clamp is installed on the knife rest, they can be swung according to a trunnion axis respectively like this.

In order to ensure can be for workpiece provides enough big free space in changing the cutter process, a useful embodiment feature of the present invention be as follows: swing arm (one or more) is installed on workbench top edge bearing one side.So just, can utilize long arm swing, thereby make the replacing position of cutter be enough to surpass or even maximum workpiece.

An alternative embodiment of the invention is characterised in that: a single swing arm is hinged on the front end of workbench, and this swing arm is according to horizontal axis swing, like this, superincumbent knife rest is in workbench when its inactive state together with cutter a side is installed at right angles.

At last, thereby for the range of movement that increases swing arm increases the range of movement of knife rest, movable joint lever or tube-in-tube structure (for example making the steam-cylinder piston device) are adopted in swing arm, a kind of like this embodiment may be useful.So just, can be also can carry out cutter changing under the superhuge situation at folded workpiece not according to a kind of circle swing motion.

Below, with reference to the accompanying drawings, give detailed description to one exemplary embodiment of the present invention, wherein:

It is the unitary side view of energy milling machine about one that Fig. 1 is one, and its tool magazine forwards its initial position (being resting position) to;

Fig. 2 has illustrated when feathering axis cutter changes the universal milling machine according to Fig. 1;

Fig. 3 has illustrated when vertical rotating shaft cutter changes the universal milling machine according to Fig. 1;

Fig. 4 has illustrated a kind of tool magazine on the basis of amplifying former figure, this tool magazine has two row's tool clamp and movable joint lever linkage devices;

Fig. 5 is a kind of universal milling machine according to Fig. 1, has a tool magazine to be hinged on its front end.

Illustrated universal milling machine comprises a fixing antitorque bearing 1, and this bearing has a top horizontal guide rail 2, and along this guide rail, the same CD-ROM drive motor of headstock 3 companies is guided and carries out lengthwise movement.In that being installed on the front end of bearing, 4, one work consoles 5 of vertical guide rail are in vertical motion through being guided on this guide rail.Have a workbench 6 on this work console 5 again, this workbench can with the perpendicular horizontal guide rail (not giving diagram) in the plane of this figure on move.The workspace of cutter and workpiece are sandwiched in zone on the workbench 6, and to constitute border 7 by a chain-dotted line represented.

From Fig. 1 to Fig. 3 as can be seen, lateral edges place at the close milling machine in the top of workbench 6 has connected a swing arm, and this swing arm is swung according to a trunnion axis 9 at the side of workbench 6, at its free end a knife rest 10 has been installed, it can 11 rotations around an axle center like this.At this above knife rest 10, one row swing blade clamping apparatus 19 separately is installed, the one end opens wide, this device can make cutter 12 insert feathering axis 13 automatically, or in the vertical rotating shaft 14 of vertical working end 15, Fig. 2 (is seen, Fig. 3) according to 45 ° of surfaces of headstock 3 for basal plane rotates in working end 15.A transmission device 16(as shown in Figure 1, this device can adopt the piston cylinder formula) be hinged on the workbench 6, its piston rod acts in the swing arm 8.Below overhanging workbench 6, a toolbox 17 is arranged, it has an end baffle 18, and knife rest is in resting position in toolbox, can protect knife rest to make it avoid contacting metal bits and stream of drill cuttings like this.

In order to change the feathering axis cutter, knife rest 10 is become replacing position shown in Figure 2 from position horizontal hunting shown in Figure 1, be to drive here by drive transmission 16, the baffle plate 18 of toolbox 17 is opened.Swing arm 8 anglec of rotation with respect to the horizontal plane is approximately 45 °, and the long-armed of this swing arm should be selected like this, bumps with workbench 6 and certain workpiece of being clipped in the workspace in oscillating motion at the knife rest 10 of a side and cutter 12 avoiding.When the upper stages edge of milling machine one side is transferred in swing arm 8 (as shown in the figure), the length of this swing arm is greater than the degree of depth of workbench 6 and the catercorner length in zone 7.Workbench 6 is along making the knife rest 10 of going up pendulum locate in such a way with the translation and the work console 5 of the perpendicular direction of drawing along vertical the moving on the guide rail 4: specific empty blade clamping apparatus 19 and feathering axis 13 are in line.This sky blade clamping apparatus 19a carries out horizontal hunting according to axis 11, thereby the axis of its center line and feathering axis forms straight line.Afterwards, the feasible used cutter 12a of action that once feeds that has the headstock 3 of feathering axis 15 transfers on the blade clamping apparatus 19a.Return after headstock 3 loosens cutter 12b in utilization, blade clamping apparatus 19a puts back, and like this, used cutter 12a just is in plumbness.For inserting a new cutter 12b, need repeat this operation, promptly, utilize travelling table 6 and gone up the toolframe of putting 10, blade clamping apparatus 19b and feathering axis 13 are formed straight line, and utilize blade clamping apparatus 19b to forward new cutter 12b to horizontal level from its upright position, and form straight line with rotating shaft axis according to the swing of axis 11.The action that further feeds of headstock 3 makes new cutter 12b transfer on the feathering axis 13 from blade clamping apparatus 19b.After this replacing process, utilize swing arm 8 knife rests 10 pendulum to get back in the toolbox 17, get back to its resting position.

Fig. 3 has illustrated a vertical rotating shaft cutter changing.The same with cutter changing shown in Figure 2, move and separately carry out, the adjustment of cutter 12 is that the rotation corresponding to the termination of swing arm 8 realizes by knife rest 10, like this, the cutter furnishing vertical direction that need be changed, its center line forms straight line with the longitudinal axis of vertical milling head 15.In this embodiment, the motion process that the cutter used is unloaded from vertical rotating shaft and the motion process that new cutter is installed on this rotating shaft do not realized by headstock 15, but finish by moving both vertically of work console 5.Yet, send under the sufficient situation at rotating shaft, in addition can by send to return headstock 15 in vertical rotating shaft 14 realize this motion process that is connected.

In tool magazine shown in Figure 4, two swing arms are hinged on the both sides of workbench, each swing arm all is made up of two

levers

30 and 31, and they connect by coupling arrangement 32 in the middle of.Linear actuator 33(i.e. a cylinder) be connected with a support 34, this support is installed in down on the lever 30, and also (the figure shown in the solid line) puts to chain-dotted line replacing position this device 33 from following position with lever 30.Another linear actuator 35 is hinged on down on the lever 30, and its piston rod is connected on the support 36, and this support stretches out from the side of upper lever 31.At the free end of this upper lever 31, a knife rest 37 has been installed so that can be once according to its longitudinal axis Rotate 180 °.In this tool magazine embodiment, this knife rest 37 has two row's blade clamping apparatus 39, and they are installed axisymmetricly, and this design is compared with the tool magazine of Fig. 1 to Fig. 3, and the

cutter

40 and 41 of twice can be arranged.As shown in the figure, utilize this tool magazine, only the cutter changing on the vertical rotating shaft 14 is fallen, this practice provides a kind of simplification of replacing mechanism of substantial, structure.In fact as can be seen, in practice, the cutter on the vertical rotating shaft 14 that need change usually will be more than the required cutter of changing on the feathering axis 13.Therefore, for the operation of a kind of automaton, utilizing programme controlled mode just to change cutter on the vertical rotating shaft, usually is more favourable, and can increase the capacity of tool magazine and be twice.Because vertical headstock will be narrower than headstock 3 usually in order to hold the fore-end of feathering axis 13, therefore, that blade clamping apparatus 39 can be installed on knife rest 37 is compacter, and in the process of cutter changing, vertical headstock 15 can not collide with the cutter on the adjacent blade clamping apparatus among the same row.For feathering axis and the cutter that need change at any special time, adopt same compactness to install to blade clamping apparatus, must need the cutter changed together to move on to one respectively so at any time and change on the position, bump with cutter adjacent in the tool magazine with the headstock of avoiding broad together with their blade clamping apparatus.Yet moving respectively of this blade clamping apparatus needs a kind of comparatively complicated transmission mechanism.For the blade clamping apparatus that will be fixed on the rotatable 180 ° knife rest is located exactly, this knife rest also can have a matrix part (for example, part shown in the dotted line when knife rest swings in inactive state).

Embodiment in 5 with reference to the accompanying drawings, being some blade clamping apparatus that a row is installed on the knife rest 20 can be rotated respectively according to the axis 22 along this knife rest longitudinal extension.Knife rest 20 is installed on the beveled end member 23 of a swing arm 24, and the free end of this swing arm is hinged on the front bulkhead 25 of workbench 6, and it can be swung according to a trunnion axis 26 like this.In order to change a cutter, this swing arm 24 can utilize a transmission device (not shown, for example a kind of piston cylinder) horizontal pendulum to a vertical means according to Fig. 1, thus knife rest 20 is together with flatly launching before headstock once row's blade clamping apparatus 21 and cutter in the above 12.Utilize suitably moving of work console 5, workbench 6 and headstock 3 and moving respectively of rotating

shaft

13 and 14, and utilize the rotation of each blade clamping apparatus 21 to move, in each case, the cutter of having used can be taken off and change a new cutter from level or vertical rotating shaft.

The present invention is not limited only to the scope of above-mentioned example embodiment.For example, swing arm can comprise two or more parts, and this part can adopt the telescopic interlocking thus can its length of conversion, has so just improved the stationkeeping ability in original state and cutter changing state.At last, in order to ensure reliable cutter changing process, provide a kind of locking or clamping device, this device acts on (for example) swing arm and the knife rest and (at its initial position, especially puts at it and carry out on the position of cutter changing).
