て刃部割出し回転させるようになっている。Conventional Technology and Problems Automatic lathes such as NC lathes usually have a housing attached to a compound rest that feeds biaxially on a bed, and a cutting tool is attached to the tip of the compound rest. It is equipped with a turret equipped with a rotating platform. However, conventional turrets generally have a rotary table with a single radial shape or a polygonal outer periphery to which several to 12 blades can be attached, and a housing holds a rotary transmission shaft and is driven by a hydraulic motor. The blade is indexed and rotated via a gear mechanism.

はいえない。However, in order to increase the number of installed cutters, it is often thought that the dimensions of the turntable should be increased, but this takes up space, makes designing the entire lathe difficult, and increases costs. Also,
Even if the above-mentioned problems are overcome, the problem of mutual interference between the attached blades occurs, which increases the difficulty in speeding up indexing. On the other hand, a proposal was made to add one more turret, but although it would be possible to double the number of blades, the problem of space occupancy and high cost still exists, and it cannot be said to be satisfactory in terms of practicality.

ことを可能にする。According to the means of the present invention having the above-mentioned characteristics, two rotary tables are provided in a single housing so as to be able to coaxially contact each other in the front and back so as to be able to rotate independently. Through this, it is possible to selectively drive and rotate one of the rotary tables using a conventional hydraulic motor, making it possible to form approximately the same number of cutter mounting seats on each of the two rotary tables, and also to form a three-piece cup. Two coupling members with the concave and convex tooth surfaces of the rings facing the same side are attached to the rear rotary table and the housing, respectively, and another coupling in which the concave and convex tooth surfaces of the rings face the side opposite to the two coupling members. If the member is attached to the front rotary table which can be shifted in the axial direction, the coupling member will also move with the shift of the rotary table and engage and disengage from the two coupling members, so that the coupling member can be engaged with and disengaged from the two coupling members. When fitted, the rear rotary table and housing are integrally engaged 1. If you shift in the opposite direction, the coupling will be disengaged and disengaged from each other, allowing both the front and rear rotary tables to rotate relative to the housing. Either of the mounts can be selectively rotated to allow indexing of the blade.

うになる。When indexing a cutter with the above configuration of the present embodiment, the hydraulic circuit system receives a command from the computer and operates the valve Sl and one of the valves S2 and S3, and the valve Sl is operated by the hydraulic motor 21. is switched to rotate from the current position of the indexing cutter in either the forward or reverse rotation direction selected so that the minimum rotation angle is required. On the other hand, a radial rotary table 11 is attached with a predetermined cutter determined by the cutting process.
Or valve S2 corresponding to either polygonal rotary table 12
or 83, depending on the operation of either plunger valve 31 or 3.
2 to move backward, thereby retracting either the pawl 311 or 321, and the corresponding transmission shaft 111 or 112 rotates in a predetermined direction at an appropriate speed via the differential gear mechanism 22. At the same time, the conduit for moving the hydraulic operating mechanism 4 of the first transmission shaft 11 forward is opened to pump hydraulic fluid. For this,
Since the transmission shaft 111 is moved forward, the coupling member 52 forming the three-piece coupling 5 is moved forward by the coupling member 51.
.. By releasing the mesh with 53, the radial rotating table 11
The polygonal rotary table 12 is released from the engagement with the housing 1 and can rotate freely, and is rotationally driven by the hydraulic motor 21, so that the predetermined rotary table 11 or 12 quickly rotates, and the cutter is placed in the cutting position. I will put it out. After the predetermined blade is indexed, the solenoid switches the valve Sl according to a command from the computer, stops the hydraulic oil in the pipe t1, and stops the hydraulic motor 21, and at the same time switches the valve S2 or S3 which was switched above. is switched and restored by the operation of the solenoid so that the plunger valve 31 or 32 advances, so that the pawl 311 or 321 bites into the split cam 1111A or 1112A again, and at the same time the plunger valve 31 or 32 moves forward. 1st
The hydraulic actuating mechanism 4 of the transmission shaft 11 is brought into communication with the conduit through which it moves backward. As a result, the first power transmission shaft 11 retreats in the axial direction, and the radial rotary table 11 retreats to move the coupling member 52 of the three-piece coupling 5 to the coupling member 5.
1.53, and the radial rotary table 11 and the polygonal rotary table are both fitted and fixed to the housing.

構成は極めて簡単で装置全体に対し場所をとらない。Invention Zero Effect According to the above embodiment of the present invention, the radial rotary table and the polygonal rotary table are used so that the turret dimensions do not change much and a number of blades can be attached to the cutter rotary table which is twice as many as the cutter rotary table in a conventional NC lathe. A rotary table turret, which is adjacent to each other on the same axis and is selectively and independently rotated by two separate transmission shafts by a hydraulic motor via a differential gear mechanism, making it possible to index the cutter, is installed on one side of both rotary tables. The transmission shaft can be moved in the axial direction together with the transmission shaft, and its axial movement can be fixed by integrally connecting with the housing by engaging or disengaging the three-piece coupling, or detaching it when indexing. By separating both rotary tables and allowing them to rotate independently, the blade and rotary table are fixed in a fixed position in the housing during each cutting operation, and at the same time, the other rotary table is also fixed. When the process changes and the cutter is changed, the control operation for indexing the cutter, that is, retracting the pawl of the split cam and using the hydraulic motor to operate the differential gear mechanism, is performed. In conjunction with the operation of selectively rotating the turntable through the
The first transmission shaft is also moved by a hydraulically actuated mechanism and can be released from its engagement with the housing, making it possible to quickly index the blade, and once indexing is completed, it can be used reliably during machining. The rotary table can be fixed to prevent the blade from moving. Furthermore, the configuration for doing this is extremely simple and does not take up much space in the overall device.

を特徴とする自動旋盤における複回転台付ターレツト。(1) Two parts are placed on the bed of an automatic lathe using a two-part feed stand, etc.
In an automatic lathe, the housing is provided with a housing so as to be fed in the axial direction, and a rotary table is provided in the housing, to which a cutter is attached and rotated by a hydraulic motor via a transmission gear mechanism, and capable of performing a predetermined indexing operation of the cutter. The turret is provided with two rotary tables arranged in front and back of each other along the same axis so that they can rotate independently, and the front rotary table is shiftable in the axial direction with respect to the rear rotary table and the housing, Each of the three coupling members has a concave and convex tooth surface formed on one side, two of which have concave and convex tooth surfaces inscribed in concentric circles on the same plane, and the other one has a concave and convex tooth surface that is inscribed in a concentric circle on the same plane. One of the three-piece couplings, which can be engaged and disengaged by shifting in opposition to the two, is installed, and the other two couplings, which can be engaged and locked at the same time, are connected to the rotating table at the rear. A turret with a double rotary table for an automatic lathe, characterized in that the front and rear rotary tables are respectively attached to a housing and are locked to and released from the housing by shifting the front rotary table.
