Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the invention as set forth in the preamble of claim 1, that is, a plurality of side-openings into which tool holders can be inserted one by one so that the axis is parallel to the main axis of a machine tool. At least one tool holder hook having a tool holder receptacle is provided on the machine frame, said tool holder being locked in the inserted state by at least one locking member provided on the tool holder hook, in particular automatically movable into the locking position. The tool holder hanger and the spindle can be moved appropriately in order to change tools in the axial direction of the spindle and to attach and detach the tool holder from the tool holder receiver. After the holder has been inserted into the spindle, the locking member can be moved to the release position to release the tool holder by means of an abutment piece that is movable relative to the tool holder, so that the tool holder can be moved in particular to the conical clamp shaft. In the front, the tool holder is provided with an engaging flange that fits into the corresponding tool holder receiver of the tool holder hanger when the tool holder is stored, and at the periphery thereof, when the tool holder is inserted into the main shaft. The present invention relates to a tool holder storage magazine equipped with tools for a boring machine or a milling machine, which is provided with two grooves at mutually opposing positions on the periphery into which an engaging piece provided on the front surface of the main shaft is appropriately fitted.

A magazine of this type as part of a machine tool is already known (brochure "Compact Center nb-h65" of Hüller-Hill GmbH, Werkzueikmasinen).

In this known magazine, the tool holder hook consists of a horizontally supported disk. A tool holder receptacle is provided at the periphery of this disk, which is open laterally, that is, in the circumferential direction.

The tool holders stored in the tool holder receiver are each locked to the tool holder receiver by a locking member. The locking member abuts against the peripheral edge of the tool holder protruding from the tool holder receptacle to achieve the purpose of locking.

The locking member is constructed and arranged to be automatically held in the locked position. In this case, only tool holders that have already been moved into a certain exchange position are automatically released.

In particular, during the exchange operation of tool holders that can hold large and therefore heavy tools, the engagement piece provided on the front surface of the spindle may fit into the groove provided on the periphery of the engagement flange of the tool holder to be exchanged. The tool holder hook must be held in correct alignment by the locking member until the coaxial alignment of the replacement tool holder with the spindle that was previously maintained by the locking member is taken over.

This problem can be solved by the present invention, which is characterized in that the locking member is provided on the retaining plate provided on the front surface of the tool holder hanger, and the locking member is provided on the retaining plate provided on the front surface of the tool holder hanger, and the locking member is provided on the retaining plate provided on the front surface of the tool holder hanger. After the engagement piece of the spindle is inserted into the flange notch from the front and inserted into the groove of the engagement flange of the tool holder inserted into the spindle, the holding member is held in order to release the locking member from the flange notch by the abutment piece. The solution is a tool holder storage magazine equipped with a tool that allows the plate to be moved to the release position.

Therefore, in the magazine configuration of the present invention, the locking member and the holding plate are installed apart from the periphery of the tool holder hook.

Since the locking element is inserted into the engaging flange of the tool holder, in particular from the front side of this flange, the locking element can act not only as alignment means but also as holding means. Therefore, even when a heavy tool is mounted on the tool holder hook and the spindle receives the tool from below the tool holder hook, there is an advantage that the tool holder can be correctly aligned and held in the tool holder receiver of the tool holder hook.

Even if the tool holder hook is not formed in the form of a disk, but is configured as a linear elongated block that can be displaced both parallel and perpendicular to the spindle axis, individual locking mechanisms can act, unlike known configurations. .

It is also possible for the locking member associated with each tool holder receiver to consist of, for example, a cylindrical pin that fits into a corresponding hole in the engagement flange.

In another preferred embodiment of the present invention, two locking members are provided on a common holding plate for each tool holder receptacle, and these locking members are connected to mutually opposing flange notches. The stop member is configured to fit therein.

If the size of the locking member is set to correspond to the groove of the engagement flange, there is no need to form a cutout in the engagement flange of the tool holder. In this case, an existing tool holder can be stored in the magazine without modifying its engagement flange.

As described in claim 4, the locking members of at least two adjacent tool holder receivers are provided on the same holding plate so that they can be moved together to the locking position or the release position. It is also possible to configure

In a preferred embodiment of the invention, the tool holder hook is supported with its axis parallel to the main axis and forms a circular magazine disk which is at least axially displaceable and rotatable. in this case,
It is preferable to provide a locking member on the holding plate of each tool holder receiver as described in claim 5.

As described in claim 6, the edge of the holding plate on the peripheral edge side of the disk is formed into a fork shape, so that the forks can sandwich a part of the tool holder inserted into the tool holder receiver from both sides. It's convenient if you do. A locking member that fits into the engagement flange groove of the tool holder to be locked can be formed by simply bending the ends of the forks.

Claim 7 describes a preferred configuration of the retaining plate. As stated in claim 7, an abutment piece is fixed to the machine frame that biases the holding plate associated with the tool holder receiver to its release position when the tool holder receiver comes to the exchange position. I can do it.

It is particularly preferred to arrange and construct the abutment pieces as described in claim 9. In this case, after the tool holder is transferred from the tool holder receiver to the spindle, the associated holding plate is released from the abutment piece again, and this holding plate immediately returns to the standby position where it holds the locking member in the locking position. be able to.

Other preferred configurations and arrangements of the retaining plate are described in claims 10 and 11.

If the locking member is configured as described in claim 12, when the tool holder moves to the main shaft, the engagement piece on the main shaft side will move the locking member away from the flange groove and return to its release position. It is in a state where it can be fitted into the engagement flange groove of the tool holder to be moved before being moved. The tool holder can thus be held in coaxial alignment with the associated tool holder receiver while the spindle moves axially relative to the tool holder to receive the tool.

As already mentioned, it is also possible to construct the retaining plates of the locking element in particular as sector-shaped elements, which can be attached one by one to the tool holder hook. however,
When the magazine is constructed in the form of a disk, the embodiment described in claim 13 is particularly preferred. That is, the holding plate is made of a steel plate with slits attached to the front surface of the tool holder hook.

Another preferred embodiment of the magazine is that the tool holder can be manually inserted and removed from the tool holder receptacle in order to replace a damaged tool, for example while the spindle is operating with a tool holder removed from the tool holder receptacle. A configuration that allows this can be considered. For this purpose, claim 15
An operating device is provided as described in Section 1, and the tool holder hook or magazine disk is moved in advance so that the tool holder receiver of the tool holder to be replaced is in front of the operating device, and then held by the operating device. Simply move the plate to its released position.

The present invention will be described in detail below with reference to embodiments illustrated in the accompanying drawings.

FIG. 1 shows a machining center equipped with a magazine according to the present invention and having a known configuration except for the magazine. 20 is a machine frame to which a column 22 is attached at the rear. In front of the column, a work table 24, preferably constituted by a cross carriage, is arranged on the machine frame.

In front of the column, a headstock 3 is movable up and down along a vertical guide frame 26 and a guide column 28 parallel to this.
Provided to guide 0. 32 is a bellows provided above the headstock to cover the guide frame and guide column.

34 is the main shaft of the headstock. The main shaft is driven by the second
As is clear from the above, this is done via the DC gear motor 36.

Referring again to FIG. 1, the headstock 30 can be moved up and down in the Y-axis direction using a not-shown up-down screw.

38 is a switchboard which houses electrical circuit elements and, for example, a CNC control device configured to suit the machining operations that can be performed with this machining center, including a process computer to simplify programming, machine operation and maintenance. do.

A magazine 40 is attached to the column 22 so as to be located above the headstock 30.

As shown in FIG. 2, the magazine 40 includes a known disk-shaped tool holder hook 42, which is rotatably supported by a magazine carriage 44 so that its axis is parallel to the main axis of the headstock. . The magazine/carriage 44 is the guide rod 4
6 and 48, the column guide body 50 is adjustable.
A gear motor 52 is used to move the magazine carriage 44 and tool holder hook 42 in the axial direction.
and a crank gear 54.

The disc-shaped tool holder hanger 42 has a plurality of tool holder receivers 58 opened in the circumferential direction on its periphery.
are provided at equal angular intervals, and the tool holder receivers 58
The tool holder 60 is installed with the axis parallel to the main shaft.
You can insert them one by one. The tool holder receiver 58 is moved to the exchange position by rotating the tool holder hook 42, and in this position the corresponding tool holder can be taken out by the spindle.
In this exchange position, the tool holder is adjacent to the headstock in the vertical movement plane of the headstock.

In order to move each tool holder receiver to the exchange position, the tool holder hook 42 is attached to a ball bearing 64.
The inner ring 66 is supported on the magazine carriage 44.

A toothed rim 68 that meshes with the drive pinion 71 of the gear motor 73 is provided on the outer peripheral edge of the outer ring 62 on the back side of the disk-shaped tool holder hook 42 .
This gear motor, which can be controlled by a CBC control device, can be used to rotate the tool holder hook.

Individual tool holder receiver for tool holder hook 5
A tool holder 8 is linked to a lock 70, and this safety device prevents the tool holder 60 inserted into each tool holder receptacle from falling off and is held parallel to the spindle axis.

The individual tool holder locks 70 are provided with a flat retaining plate 72, preferably sector-shaped, for each individual tool holder receptacle, the inner end of which is located at a radial distance from the axis of the tool holder hook 42. There is a mounting screw 74 so that the tool holder hanger 42 can be lifted from the front (Fig. 7).
And it is attached to the tool holder hook by a disc spring 76 attached thereto.

The end of the holding plate facing the periphery of the tool holder hook is formed into a fork shape, and the prongs 78 and 80 of the fork hold the tool holder 60 inserted in the corresponding tool holder receiver 58 at a part of the periphery. (Fig. 6 and Fig. 7a).

The tool holder receiver 58 is a tool holder hook 42
A partially circular notch is formed on the periphery of the inner surface 8.
It is constructed in a known manner by forming a seam piece 84 having a trapezoidal cross section along 2.

The tool holder 60, which is inserted into the tool holder hook for storage, is equipped with an engaging flange 86, and a flange notch 8 is formed on the periphery of the tool holder on opposite sides of the diameter.
8 and 90 (FIG. 6) are uniformly sized holders. The engagement flange 86 is provided with a circumferential groove 92 (FIG. 7a), and the centering piece 84 positively engages with the circumferential groove when the tool holder is inserted into the tool holder receiver.

When the tool holder is inserted into the main shaft 34, the engaging piece 94 arranged next to the main shaft engages the flange notch 88,
90 and locks the tool holder onto the main shaft so that it cannot be rotated.

When the tool holder is in storage, the flange notches 88, 90 work together with the individual tool holders and the locks 70 to prevent them from falling out of the tool holder receivers, and work with the joint pieces 84 to maintain the axis. Align parallel to the principal axis.

For this purpose, the forks 78, 80 of the fan-shaped retaining plate 72 of the tool holder lock are provided with claw-like locking members 96, 98 formed by bending the tips of the forks at approximately right angles before being hooked onto the tool holder.

These claw-like locking members 96 and 98 are attached to the tool holder 6.
0 flange notches 88 and 9 of the engagement flange 86
0 to press the engaging flange against the joining piece 84, and since the joining piece has a prismatic cross section and engages with the peripheral groove 92 of the engaging flange, the main axis and the axis are parallel to each other. Align the tool holders.

The length of the claw-like locking members 96, 98 is such that the claw-like locking members 96, 98 are
It is set to engage with the engagement groove over its partial length at the engagement position shown by the dotted line in Figure A. With this configuration, as will be described in detail later, when the tool holder moves to the main spindle, the main spindles can be engaged with each other facing each other without coming into contact with the locking members 96 and 98 that are still in the locked position in the flange notch. It is advantageous that the pieces 94 can fit into the flange recesses 88, 90 of the engagement flange 86.
A special advantage resulting from this is that, during the transition of the tool holder onto the spindle, the engagement flange 86 is first moved only by the pawl-like locking elements 96, 98, and then by the engagement piece of the spindle and said engagement piece. Finally, the engagement piece 84 of the tool holder receiver 58 is pressed into contact with the engagement piece 84 of the tool holder receiver 58 by the stop member.
The corresponding tool holder is completely transferred to the spindle,
It is held in a coaxial relationship with the main shaft until it is tightened.

Therefore, the claw-like locking members of the fan-shaped holding plate 72 also serve as an alignment device that aligns the flange notches 88, 90 with the engagement pieces 94 on the main shaft side.

As already mentioned, only the engagement piece 94 serves to hold the engagement flange 86 during the final stage of the transition of the tool holder to the spindle. This is because while the engaging piece is fitted into the flange notch of the engaging flange 86, the claw-like locking members 96, 98 of the fan-shaped retaining plate 72 are released from the flange notch. Because the tool holder or its engagement flange can be radially separated from the corresponding tool holder receiver 58 of the tool holder hanger 42 when the tool holder is transferred to the spindle, only the engagement piece is removed from the engagement flange at the final stage of the transfer. It is necessary to hold the

Locking member 9 from flange notches 88, 90
6.98's withdrawal will be forced. For this purpose, on the back side of each holding plate 72, for example, a bolt-shaped stopper piece 10 is screwed onto the holding plate and passes through the hole 102 of the tool holder hook 42 with some play left in the radial direction.
0 is set.

An adjustable abutment screw 10 provided on an abutment piece support 106 fixed to the entire abutment piece 100 of the holding plate 72
By coordinating common abutment members formed as 4,
The abutting screw 104 is positioned within the vertical movement plane of the main shaft.

To carry out a tool holder exchange, the disc-shaped tool holder hook 42 is moved axially to the left in FIG. The mating piece 100 is aligned with the mating screw 104.

When the tool holder shaft 108 enters the main shaft due to this axial movement of the tool holder hook, the abutment piece 10
0 approach the abutment screws 104 and abut each other at the final stage of this axial movement. As a result, the retaining plate 72 is lifted off the tool holder hook 42 in a biased manner as seen in FIG. This is made possible by the inherent elasticity of the retaining plate 72 held by the mounting screws 74.

As already mentioned, when the engagement piece 94 of the main shaft fully fits into the flange notch, separates from the engagement flange, and comes into pressure contact with the seam piece 84, the locking members 96, 98
The abutting screw 104 is arranged so that it first leaves the flange notch.

The process of replacing the tool holder will be described in detail below with reference to FIGS. 2 to 5.

If there is no tool holder in the spindle and the CNC control device is used to move the tool holder 60, which holds, for example, a drill stored in the magazine 40, to the lower exchange position, the desired work program will be started. The first step must be carried out. At this point, the main shaft 30 is still in its initial downward position (FIGS. 1 and 2).

In order to transfer the tool holder to the spindle, first the magazine 40 is moved to the left in FIG. 3 to a standby position by a carriage drive 56 controlled by a CNC controller. Next, the headstock 3
0 moves to the transition position and the main shaft 34 aligns with the tool holder 60 in the standby state (FIG. 3).

The magazine 40 then moves to the right in FIG. 4 under the action of the carriage drive 56 in order to transfer the tool holder 60 to the spindle.
0 axis 108 enters the main axis.

During this operation, when the main shaft side engaging piece 94 (FIG. 7) fits into the flange notches 88, 90 (FIG. 6), the locking members 96, 98 also engage the flange notches 8.
It is within 8,90. At the end of this movement of the magazine 40, the abutment piece 100 abuts the abutment screw 104, so that the locking members 96, 98 are lifted out of the flange notches (FIG. 4).

A tool holder shaft 108 is clamped within the main shaft. Since the tool holder is released from the holding plate or its locking member, the headstock can now be moved downwards into the working position and the engagement flange of the tool holder is released from the tool holder receiver (FIG. 5). ).

As can be seen from FIG. 5, the tool holder hook 42 remains in the transfer position until the tool of the tool holder transferred to the spindle is removed and the holder is returned to the magazine. That is, after the corresponding machining is completed, the headstock is moved again into the magazine 40, and the engaging flange of the tool holder is positively engaged with the tool holder receiver 58 hooked to the tool holder. After the tool holder shaft is released within the main shaft, the tool holder is removed by moving the magazine 40 to the left in FIG. The tool holder is fixed to the tool holder receiver by engaging the notches 88 and 90. Next, the gear motor 73 drives the tool holder hook to the standby position for the next tool scheduled to be inserted according to the work program, and the above-described operation for delivering the next tool holder to the spindle is repeated.

As is apparent from FIG. 1, the magazine 40 is housed within a housing 110 that surrounds most of the tool holder hanger 42.

Further, as is clear from FIG. 5, the holding plate 72 of the tool holder receiver 58 which occupies the exchange position is attached to the tool holder 6 taken out from the tool holder receiver.
As long as the tool 0 is within the spindle, it remains lifted from the tool holder hanger 42.

In FIG. 1, the lower part of the housing 110 has arcuate guard rails 112 and 11 connected to the tool holder hook.
4 to shield the lower part of all tool holder receivers except the tool holder receiver at the exchange position. This guardrail must be constructed in such a way that it does not impede the axial movement of the tool holder hook 42 and is therefore attached in a suitable manner, for example to the magazine carriage 44, the details of which are not shown in the drawings.

FIG. 9 shows a configuration in which, unlike the configuration shown in FIG. 7, an abutment piece 116 that cooperates with an abutment piece 100 of the holding plate 72 is formed directly on the headstock. This abutment piece 116 has an inclined surface 118 which runs onto the abutment piece of the holding plate 72 in the exchange position as soon as the headstock reaches the exchange position above it. That is, when the headstock is lowered to the initial position again after the tool holder is delivered, the holding plate 72 is released from the abutment piece 116 again and can come into contact with the front surface of the tool holder hook.

In another embodiment of the magazine, each retainer plate 72 is associated with a recovery spring 120. This spring always holds the retaining plate in the locked position. That is, the entire surface is brought into pressure contact with the tool holder hanger. To obtain this configuration, the spacer bolt 12 screwed into the tool holder hook
2 through a retaining plate, a recovery spring 120 in the form of a compression spring is wound around this bolt, one end of the recovery spring is placed outside the associated retaining plate, and the other end is secured to a screw nut 124.
The base plate 126 is fixed to the base plate 126, respectively.

However, if the recovery spring 120 is attached directly to the abutment piece 100 of the holding plate 72 as shown in FIGS. 7 and 7a,
One end may be brought into contact with the back side of the holding plate, and the other end may be brought into contact with the shoulder of the abutment piece.

FIG. 10 shows a configuration in which the recovery spring configuration of FIG. 9 is modified. In this case, they are arranged at intervals of 90°, for example. An abutment ring 130 is attached to the front of the retaining plate 72 with four spacer bolts 128 similar to the arrangement shown in FIG. Between the retaining plate and the abutment ring there are individual compression springs 132 which act to keep the individual retaining plate pressed against the front surface of the tool holder hanger at all times.

The magazine can also be constructed so that the tool holder can be manually moved into and out of the tool holder receptacle. For this purpose, for example, the abutment piece support 106
(Fig. 7, Fig. 7a) Or, the operating device is fixedly installed near the replacement position. This operating device is, for example, a first
As shown in Figure 1, an abutting piece 1 is attached to the piston rod 136.
It consists of a compressed air-operated cylinder device equipped with 38. Guide rod 14 passing through the abutment piece
0 prevents the piston rod from rotating.

To manually change the tool holder, the operating device is actuated in such a way that the holding plate 72 holding the tool holder to be replaced is moved via the abutment piece 138 to the release position. After the tool holder is inserted into the corresponding tool holder 58, the abutment piece 1
38 is returned to the released position, in which case the corresponding retaining plate 72 automatically returns to the locked position under the action of the compression spring 132.
