A guide bush 102 is fixed to the cylinder 87a. A key groove 102a is formed in the guide bush 102 in the vertical direction in the figure, that is, in the direction of the arrows ■ and J. A piston 92 is provided in the cylinder 87a, and a key 92a fixed to the piston 92 is inserted into the key groove 102a. In this way, they are fitted and engaged so that they can be freely projected and driven only in the directions of arrows 1 and J. Note that 93.95 is a port for supplying pressure oil to the cylinder 81c, 96.97 is a port for supplying pressure oil to the cylinder 87a, and 99.100 is a pressure oil supply port for driving the hydraulic morph.

On the other hand, a support stand 72 is provided on the left side of the bed 60 in FIG. 1, and a replenishment tool magazine 73 having the same configuration as the tool magazine 65 is installed on the support stand 72. In the tool magazine 73, tools 43.49 of tg number are detachably installed in a tool head 35.50, and a predetermined number of tools are provided by driving a swing vane 69 via a sprocket 66.67. At tool change position Z1,
The tool 43,49 to be replaced can be positioned.

Complex machining turning F! Since X1 has the above configuration, when processing a workpiece, the cylinder 47 is driven,
The tool holding stand 2 is moved and retracted in the direction of arrow S in FIG. In this state, the sprockets 66 and 67 of the tool magazine 65
The tool magazine pawl 69 in the chain 69
Among the tools set in a, the tool to be used for machining is positioned at the tool indexing position X corresponding to the head hole 3 of the tool holder 2. When the tool is positioned at the index position x and the tool and the head hole 3 are aligned as shown in FIG. Force them to retreat and evacuate in the direction of the arrow.

In this state, the tool head 35, which rotatably supports the main shaft 42, is inserted into the hole 3 of the holder 2 in order to cause the tool holder 2 to protrude in the direction A by driving the cylinder 47.

At this time, the dog clutch pawl 19a of the transmission shaft 19 and the main shaft 4
2 clutch pawls 45 engage, but both clutch pawls 19
Even if the protrusions of 1.45 come into contact with each other, the transmission shaft 19 retracts against the spring 20, so the tool head 3
5, and even if the protrusions of the clutch pawls engage with each other, both clutch pawls 19a and 45 mesh simultaneously with the rotation of the transmission shaft 19.

Next, when the supply of pressure oil from the boat 26 is stopped and pressure oil is supplied from the boat 27 into the cylinder 25, the rod 29 protrudes 1' in the direction of arrow C together with the elastic restoring force of the spring 31, and the rod 29 The 29 serrations 30 engage the 13 fillets 39 on the straight shank 37 of the tool head 35.

In this state, when the qrad 29 is further moved in the direction of arrow C, the shank 37 is pushed in the C direction and moved in the S direction by the wedge action of the serenoyons 30 and 39.

Then, by pressing the shank 37 in the C direction, the shank 37 comes into contact with the boundary points PKI and PK2 between the escape part 3b and the inner part 3a of the hendo hole 3, and contacts the points PKI and PK2 and the rod 29 at three points. Based on the fact that the shank 37 is securely held in the head hole 3 and the shank 37 moves in the S direction,
The mold on the head hole 3 side of the tool holding stand 2 is pressed against the end surface 36a of the boss portion 36 of the sole head 35 by a predetermined contact pressure, and as a result, the sole head 35 is pressed against the head hole 3 side.
It is accurately installed and held in the specified position within the device.

Further, the tool 43 is attached to the chain 69 via the tool head 35, but the tool 43 can move to some extent in the directions of arrows C and D in FIG. 2 and the directions Q and R in FIG. If this is not allowed, machining A43 will result in the rod 29 being misaligned between the tool head 35 and the head hole 3 when the tool 43 is mounted on the tool holder 2.
During clamping, a force mainly in the direction D is received from the chain 69 side, causing positional deviation, making it impossible to clamp the tool 43 at an accurate cutting edge position. Therefore, when the tool holder 2 is moved in the direction A to clamp the tool 43 and the shank 37 of the tool head 35 is inserted into the head hole 3, the tool holder 69b is moved as shown in FIG.
The tip of the stopper pin 69r contacts the block 2b provided on the tool holder 2, and the stopper pin 69r is moved in the S direction against the elasticity of the coil spring 69t. Then, the tapered portion 69s, which had been in abutting engagement with the tapered hole 69'' of the bushing 691 due to the elasticity of the coil spring 69t, is released from the abutting engagement state, and a gap is formed between the tapered portion 69s and the tapered hole G9j. A slight gap will appear. Then, the stopper pin 69r becomes free to move to some extent in the directions of arrows C, D, Q, and R in the tapered hole 69j, and the stopper pin 69r engages through both ends of the tool magazine claw 69a1, and thus the tool magazine claw 69a.
The tool 43 held by the tool head 35 can be moved in the C, D, Q, and R directions via the four legs 69k. Then, when the tool head 35 is held by the clamping rod 29, even if the tool head 35 is moved in the C or S direction, the tool magazine claw 69
Since a is free to move with respect to the chain 69 together with the tool head 35, no force is exerted on the tool head 35 from the chain 69 side, and the tool 43 is accurately mounted and held on the tool holder 2. Note that by moving the stopper pin 69r in the S direction, the tool magazine claw 69
a can be moved to an extent that can compensate for the misalignment between the tool head 35 and the head hole 3 (i.e., when the tool head 35 is installed in the head hole 3, the tool head 35 is moved from the chain 69 side to C, D). and (to the extent that no force is applied in the Q and R directions) is sufficient.

Furthermore, before the stopper pin 69r comes into contact with the block 2b, or when the stopper pin 69r separates from the block 2b and the contact engagement relationship is released, the stopper pin 69r is moved in the T direction by the elasticity of the coil spring 69t. Since it is biased, the tapered portion 69s and the tapered hole 69J come into close contact with each other, and the tool magazine claw 69a and the tool 43 are securely held against the chain 69 and move inadvertently in the C, D, Q, and R directions. There's nothing wrong with that. In addition, since the pushin 691 is made of an elastic material such as rubber, the tool magazine claw 69a
The tool head 35 can be elastically moved in C, D, Q, and R directions relative to the chain 69, so when inserting the tool head 35 into the head hole 3,
Even before the tool head 35 becomes completely free to move due to the movement of the stopper pin 69r in the S direction, some movement in the C1D, Q, and R directions is possible due to the elastic deformation of the bushing 69i. The attachment to the tool holding table 2° can be carried out more smoothly without applying excessive force to the chain 69.

When the motor 16 is rotated in this state, the rotation of the motor 16 is caused by the drive pulley 15,
Belt 13, driven pulley 12, pulley shaft 10, transmission shaft 1
9 and the clutch pawls 19a, 45 to the main shaft 42 to rotate the rotary tool 43 provided on the main shaft 42,
Desired rotation work can be performed.

At this time, the tool head 35 is processed while being attached to the chain 69 of the chain-type one-tool magazine 65, but the indexing point fiX is set at the bent part where the chain 69 is wound around the sprocket 66. In that part, the chain 69 is bent in an arc shape, so that the space between adjacent tool heads 35 and 50 attached to the chain 69 is wider than in other straight parts. Chain type 1 tool magazine 65
Even if machining is performed with the work piece attached to the chain 69, there will be no interference between adjacent tools on the chain 69, or between the workpiece and other tools on the chain 69.

When the work is completed, the rotation of the motor 16 is stopped and pressure oil is supplied from the boat 26 to the cylinder 2 as described above.
5, the clamping rod 29 is retracted in the direction of the arrow, and the tool holding table 2 is retracted in the S direction by the cylinder 47, so that the tool head 35 is removed from the head hole 3 together with the tool 43. It will be done.

Therefore, by immediately driving the sprockets 66, 6 and 7, the tool used for the next machining is positioned at the indexing position Mx. The tool selection operation by the magazine 65 is performed smoothly.

In the above embodiment, the tool head 35 with a built-in spindle 42 was selected and inserted into the tool holder 2, but as shown in FIG. 6, a tool head 50 having a turning tool 49 was selected and inserted. Of course, it may also be used.

In this way, the tools 43 and 49 in the tool magazine 65 are successively mounted on the tool holder 2 to perform predetermined machining, but as many types of workpieces are being machined, only the tools stored in the tool magazine 65 are used. In this case, a situation arises in which proper processing cannot be performed. In that case, before machining a new workpiece, move the carriage 46 in the A and B directions and the cross slide 63 in the E and F directions, and move the tool magazine 65 on the cross slide 63 to the specified tool exchange position. position. In this state, the chain 69 is rotated via the sprocket 66.67 of the tool magazine 65, and the tool 43 or 49 to be replaced in the tool magazine 65 is moved to the tool exchange position UZ together with the tool head 35.50.
2, and then move it to sprocket 6 of tool magazine 73.
6.67 is driven to rotate the chain 69, and the tool 43 or 49 to be replaced in the tool magazine 73 is moved together with the tool head 35.50 to the tool changing position Z1.

When the tool 43 or 49 to be replaced is positioned at position Z2 and Zl, respectively, the ATC device 71 is driven and the pressure oil supply port 10 of the hydraulic motor 91 is activated.
Pressure oil is supplied to the hydraulic motor 91, and the output shaft 91 of the hydraulic motor 91 rotates. Then, the shaft cylinder 87 rotates via the key 90, and the guide bushing 102 and the key 92 are rotated.
The piston 92 rotates by the same angle via a, so the main body 81a also rotates through the slide arm 83 and the tool holder 82A18.
2B, as shown in FIG. 10 ta+, the main body 81a and the slide arm 83 are moved from the previously retracted position ES to a tool exchange position where the tool is exchanged;
That is, each holding part 82A, 82B is connected to each tool magazine 65.7.
The tool is positioned at a position that matches the tool exchange positions Z2 and Zl of No. 3. As a result, the tool holder 82A, 82B and the tool 43 or 49 positioned at the tool exchange position Z2, Zl of each tool magazine 65.73 have their holding tube 82d and shank 37 aligned with the imaginary line in FIG. Figure 10tbl, (
Match as shown in cl. In this state, when pressure oil is supplied from the boat 97 to the cylinder 87a of the shaft cylinder 87, the piston 92 is pushed up in the direction of the arrow 1, and the main body 81a fixed to the piston 92 also moves in the 1 direction. Then, the slide arm 83 and tool holding parts 82A, 8
2B also rises in one direction, and the tool 43 at positions Z2 and Zl
Or the shank 37 of 49 is shown in FIGS. 9 and 10 [dl
As shown in the figure, it fits into the intermediate holding cylinder 82d. When the shank 37 is fitted into the holding cylinder 82d, the shank 37
The lock pinot 82e is attached to the small diameter portion 37b of the coil spring 82f.
The elasticity of the tool 43 or 49 prevents the tool 43 or 49 from accidentally falling off from the holding parts 82A, 82B together with the tool holder 35.50.

Now, for example, as shown in FIG.
Assuming that A is positioned at position Z2 and the holding part 82B is positioned at position Z1, the tool holder 6 is placed in the holding part 82A.
The tool 43 or 49 to be replaced is held in the holding part 82B, and the tool 43 or 49 that will be used in the next machining of the tool holder 73 is held in the holding part 82B. 93, and drive screws 1 to 85.
85 is moved backward in the G direction, and therefore the tool holding portion 82A1
82B is moved in the G direction together with slide arms 83 and 83. Then, the tool 4 in the tool holding parts 82A and 82B
3 or 49 is the magazine claw 6 of each tool magazine 65.73
9a, as shown in FIG. 10, tel. Therefore, pressurized oil is supplied to the supply port 99 of the hydraulic motor 91, and the ATC arm 81 is now reversed by 180 degrees in the opposite direction to the previous direction, and the tool holder 82A is positioned as shown in FIG. 10 (fl). z1, the tool holder 82B is positioned at a position corresponding to position Z2.Furthermore, pressurized oil is supplied to the port 95, and each tool holder 82A, 82B is moved in the H direction via the piston 85.85. Make it stand out.Then,
As shown in FIG.
The tool A 43 or 49 held in the tool A 43 or 49 held in the tool holding part 82A of the tool magazine 65 is stored in the magazine claw 69a that had been held until then, and the tool 43 or 49 in the tool holding part 82B is stored in the tool holding part 82A of the tool magazine 65. 49 is stored in the magazine claw 69a where it was held until then. Next, pressure oil is supplied to the port 96 to move the ATC arm 81 to the piston 9.
2, each tool 43 or 49 is pulled out from the holding cylinder 82d of each tool holding part 82A, 92B in such a way that the lock pin 82e is retracted against the elasticity of the coil spring 82f, and each tool 43 or 49 is removed from each magazine. In the claw 69a, the 10th
It is retained as shown in the figure (hl).

In this way, the chains 69 of the tool magazines 65 and 73 are driven to rotate, and the unnecessary tools and new tools used for the next machining are sequentially moved to the exchange positions Z2 and Zl.
The tools are exchanged between the magazines by positioning the ATC arm 5 81 and inverting it 180 degrees at a time. When the replacement of tools according to the prescribed provisions is completed, connect the supply port 99 or 10 of the hydraulic motor 91.
Supply pressure oil to the ATC arm 81 as shown in Fig. 10.
It is driven to retreat to the retreat position ES shown in +. Next, the gear 9 is moved in the E and F directions to begin machining operation for the next workpiece. At this time, since the ATC arm 81 is at the predetermined retracted position ES, the tool magazine 73 and the ATC arm 81 will not interfere with each other and normal machining operation will be hindered, and the machining operation will be performed smoothly.

Furthermore, in the above embodiment, the case was described in which the tool holding stand 2 was provided so as to be movable and retractable with respect to the tool magazine 65 in the directions of arrows A and B using the cylinder 47, but the tool holding stand 2 and the tool magazine 65 is the tool holding stand 2 when exchanging tools.
Needless to say, any configuration may be used as long as it is movable and retractable relative to the tool magazine 65. For example, the tool holding base 2 may be fixedly provided on the cross slide 63, and the tool magazine 65 may be mounted on a cylinder. Of course, it is also possible to provide it movably with respect to the tool holding table 2 in the directions of arrows A and B using an appropriate reciprocating drive handle such as the above.

Furthermore, when the tool magazine 65 side is provided movably in the directions of arrows A and B, as shown in FIG. A dustproof cover 65b that can cover the noyank 37 is provided, and when the tool magazine 65 is moved in the direction B, that is, when the tools 43 and 49 are held on the tool holder 2, the third image 1g! As shown by the lines, the yanks 37 of the tools 43 and 49 other than the tools 43 and 49 held on the tool holding table 2 are stored in the dust-proof cover 65b, and the yanks 37 are free from chips and the like generated during machining. When configured to prevent the tool heads 35, 50 from accumulating.
Since the tool holding operation between the head hole 3 and the head hole 3 is performed under a clean noyank 37, it is possible to maintain a smooth tool exchange operation over a long period of time. In addition, the dust cover 65
b is a chain 69 as shown in FIGS. 3 and 13.
