Abstract

PURPOSE:To make it possible to positively perform the operation of a tool changing arm at high speeds by performing reciprocating and turning motions of the tool changing arm, and clamping and unclamping of a tool in a machine tool by one driving system. CONSTITUTION:An arm supporting shaft 12 for giving reciprocating and turning motions to a tool changing arm 43 interlocked, by a sliding mechanism 18 and a rolling mechanism 29, with a double face positive motion cam 9 having a forward-reverse operating cam shaft 4 is provided in the automatic tool changing device 2. Further, main and slave arm bodies 48, 49 of the tool changing arm 43 having fan gear tooth parts 53a, 53b are respectively engaged and linked with each other, and can be opened and closed through a transmission gear 61. And a rocking mechanism abutting on the end face 53c of the mating fan gear tooth parts 53a, 53b is provided in conjunction with front-back motion of the tool changing arm. Accordingly, a tool T can be stored in a spindle head 1 and a tool magazine by giving a front-to-back motion and turning motion to the tool changing arm 43 by means of one driving source.

I l! i'l) However, performing the reciprocating and turning operations for the tool exchange arm using separate drive systems requires time loss due to the start command, stop confirmation detection, and startup and stop of the power system for each operation. In addition, when clamping and unclamping tools using a tool exchange arm using spring force, this can be done easily, but requires a special drive source. Although there is an advantage of not
On the other hand, if you try to operate the tool change arm at high speed, the inertia force acting on the tool will increase rapidly, the gripping force of the tool will become unstable, and the problem of tool release will occur. If the setting is too large, it will be difficult to freely attach and detach the tool, so those with a spring-based gripping structure naturally have problems such as putting a limit on tool exchange time. Therefore, in order to speed up tool changing, a cam is used to operate the reciprocating and rotating movements of the tool changing arm with a single power source, while the tool is reliably clamped and unclamped using a separate drive system. Although some devices have been developed, the present invention ensures the operation of the tool exchange arm by performing the reciprocating movement, rotational movement, and clamping/unclamping of the tool in one drive system. It is an object of the present invention to provide an automatic tool changer that can increase speed and reduce tool change time. (Means for Solving the Problems) In order to solve the above-mentioned technical problems, the present invention provides an automatic tool changer that is interposed between a machine tool and a tool magazine, and includes a cam that is rotated forward and backward by a drive source. An arm support shaft is provided on the double-sided positive cam having a shaft, which is connected by a slide mechanism and a rotation mechanism to provide reciprocating and rotating motion to the tool exchange arm installed at the tip. The pair of main and slave arm bodies each have fan-shaped teeth and are interlocked and connected, and the left and right master and slave arm bodies are provided so that they can be opened and closed jointly via a transmission gear. An automatic tool changer with a small number of main and slave arms (both of which are equipped with a locking mechanism having a lock bar that comes into contact with the end surfaces of the respective fan-shaped teeth in relation to the back and forth movement of the tool change arm) (Function) The left and right main and slave arm bodies of the tool exchange arm each have fan-shaped teeth and are interlocked and connected.
The slave arm body is provided so as to be able to be opened and closed jointly via a transmission gear, and is provided with a lock n#i having a lock bar that comes into contact with the end surfaces of mutual fan-shaped teeth of the left and right main and slave arm bodies, Immediately before retracting the tool exchange arm and storing the tool in the spindle head and tool magazine, the lock is released to allow the main and slave arms to be opened, and the tool exchange arm is moved forward to remove the tool from the spindle head and tool magazine. It locks instantly at the initial stage, making it impossible to open the main and slave arms. (Embodiment) Next, an embodiment of the present invention will be described according to the drawings. In the figure, 1 is a spindle head of a machine tool, and an automatic tool changer 2 is removably attached to the spindle head 1. The spindle head 1 is configured to move together with the spindle head 1. Reference numeral 3 denotes a main body frame of the device 2, which is formed into a substantially housing shape, and a cam is disposed between a front frame 3a on the left side of the main body frame 3 in the drawing and an upper support frame 3c provided in a manner hanging down from the upper frame 3b. A shaft 4 is rotatably supported, and the shaft 4 serves as a drive shaft for the mounting E2.
For example, it is directly connected to a hydraulic motor or an electric motor and rotated forward and backward at a predetermined rotation angle, or forward and reversed by a rack or the like, and in this example, a rack is used as an example. Reference numeral 5 denotes a driving fluid cylinder that is installed in the body frame 3 at a predetermined position on the upper frame 3b with its piston rod 6 facing downward and extending through the body frame 3, and the tip of the piston rod 6. A rack 7 having a predetermined length is attached to the rack 7, and the rack 7 is meshed and connected to a pinion 8 keyed to the cam @4. The camshaft 4 has a substantially disk-like shape having a predetermined diameter in the center thereof, and a rotating cam groove 10 on the front side surface 9a for giving rotation to the arm support shaft 12, which will be described later.

<Angle position 1. '. (Stopped i'-1-11-shi4', se16 shim member; press j()) The main and slave arm bodies 48 and 49 of the JEE L T tool exchange arm 43 are expanded and moved to the unclamped position. , the locking member 69 of the locking mechanism 65 is brought into contact with the side surface of the fan-shaped toothed portions 53a and 53b, and the stopper rod 76 of the lock release mechanism 72 is brought into contact with and engaged with the side surface of the lock lever 68 of the locking mechanism 65. In this state, when the driving fluid cylinder 5 is operated to change the tool, the camshaft 4
Then, the positive cam 9 is rotated in the direction of the solid line arrow (forward rotation). During the rotation process of the positive cam 9, the trochanter 22 moves in an angular range aO to a1-β1 from the starting point aO of the longitudinal cam groove 10.
The slide mechanism 18 and the rotation mechanism 29 are
is in the stop area, and during this time the roller 4 of the arm opening/closing part 27
2 is rotated in the direction of the arrow, and as shown in FIGS. 9(a) and 9(b), the pressure on the cam member 56 is released and a torsion coil spring 59 (in the drawings, the road body is illustrated as a tension spring)
Due to the restoring force, the main/slave arm bodies 48, 49 are closed from the expanded state and clamp the tool T. Due to this clamping operation, the locking member 69 that is in contact with the side surfaces of the fan-shaped teeth 53a, 53b is released, and is guided by the guide frame 70 by the restoring force of the torsion coil spring 59, and the locking surface 69aG is fixed to the fan-shaped teeth 53a, 53b. The main/slave arm bodies 53a, 53b are locked by coming into contact with the end face 53c of the arm 53b. In the process of the trochanter 22 moving through the angular range a1 to a3=β2+β3, the arm support shaft 12 is moved forward by a distance S. Along with this forward movement, the tool exchange arm 4 attached to the same tip
3 is also moved, and the spindle head 1 and the tool T of the tool magazine M are removed, resulting in the state shown in FIG. 10 (aHb). With this forward movement, the stopper door 6 of the lock release mechanism 72 is disengaged from the lock lever 68, and the release lever 75 is returned by the restoring force of the torsion coil spring 78, and the stopper rod 67 is moved from the lock lever 6 of the lock mechanism 65.

In other words, as shown in Fig. 3, the rotation cam groove 1
Since the rotation mechanism 29 is activated when the trochanter 36 transferring 0 passes the terminal end b1 of the stop E area γ1, the tool exchange arm 43 moves forward and rotates within the angle range a3 to bl=01. At the time when the tool exchange arm 43 starts rotating, both the left and right drawing tools have been removed and advanced to a position where they can be rotated, and the slide n mechanism 18 is stopped at the forward end position a3. Then, in the process of the trochanter 36 rolling through the angular range b1 to b3-γ2+γ3 of the rotating cam groove 10, the tool exchange arm 43 is rotated 180 degrees, and the first
In the state shown in FIGS. 0(a) and 0(b), the left and right tools T are exchanged. During this time, the slide mechanism 18 moves in the angular range a3 to a4 = β
4 is stopped, and then activated again from the end a4 of the stop area β4, the arm support shaft 12 starts to move backward, and in the angle range a4 to b3 = 02, the tool exchange arm 43 is rotated and retreated at the same time. is given, and the rotation mechanism 29 is stopped at position b3. Then, when the arm support shaft 12 is retreated from the state shown in FIG. 10 (aHb) and the tool exchange arm 43 approaches the main body frame 3 as shown in FIGS. 11 (a) and (b), the stopper of the lock release mechanism 72 During the process in which the rod 75 is brought into contact with the end 68b of the lock par 68 of the lock mechanism 65 and then retracted by 11, the lock lever 68 is rotated about the shaft 67, thereby the lock par 69 is pulled out, and the main/slave The locked state of the arm bodies 48 and 49 is released. Therefore, the tool T is completely removed from the spindle head 1.
The lock will be released before the tool T is fully inserted into the tool pot (not shown) of the tool magazine M. For example, if the weight of the tool T is greater than the spring force of the torsion coil spring 59, the main and slave arms 48 and 49 try to open, but since the shank portion 83 of the tool T is inserted a considerable length into the spindle head 1 and tool pot, the displacement of the tool T is restricted, and the main and slave arms Body 48.
The expansion of 49 is very slight, and the main/slave arm body 48.4
9 and the gripping groove 84 of the shank portion 83 never come out of engagement. Therefore, with this lock released, the tool T can be inserted by retracting the tool exchange arm 43, and when the trochanter 22 reaches position a6, the slide mechanism 18 is stopped and the tool T is fully inserted. When the tool T is inserted, a pull rod (not shown) operates in the spindle head 1 to fix the tool "1".
