The gripping arm 20 is attached to a gripping arm mounting seat 22 provided at the other end of the tool post 160 having the x-axis servomotor 16 mounted at one end, as shown in the gripping arm exploded view of the present invention in FIG. A first rotating cylinder 24 and a second rotating cylinder 25 are provided at both ends of the holding arm main body 23, and the first rotating cylinder 24 is mounted on the holding arm mounting seat 22 and The rotary cylinder 25 is fitted to the fixed seat 26A on which the hydraulic gear 26 is fixed. The characteristics of these first and second rotary cylinders 24 and 25 are such that they can perform a semicircular rotation of 180 ° and a swiveling operation of 90 °, respectively, and the hydraulic thrust 26 is formed in two pawls in the present invention. Although the work or the processed product can be held between them, it is naturally possible to form it with two or more claws.

As shown in FIGS. 3 and 4, the table 30 is provided in the vicinity of one side of the lathe body 10 when the holding arm 20 is semi-circularly rotated and pushed out, and the work tray 32 is rotated on the upper surface thereof. Also, it is mounted so that it can be moved up and down, and it has the same function as being able to rotate by a predetermined angle with an internal "indexing device" by hydraulic control, and the column for accommodating five workpieces 33 at equal intervals on the periphery of the work tray 32. 34 and one processed product 33 'are provided with storage columns 34' (more storage columns may be provided at equal intervals), and some wires are erected around the storage columns 34, 34 ', respectively. As a result, the hollow metal column 340 is assembled, and the workpiece 33 left stacked and left in the storage columns 34 and 34 'by the hydraulic slag 26 is scooped out, or the processed product 33' which has been processed is sunk. Figure showing the stool to put and leave It is. That is, the holding arms 20 are piled up in the accommodating column 34, and the workpieces 33 waiting are picked up one by one and sent to the machining, and when the machining is completed, they are returned to be piled up in the container 34 '. As the operation is repeated, the storage column 34, which was originally filled with the workpiece 33, gradually took away the workpiece and became empty, and the other processed product 33 'was emptied. The storage column 34 'is formed, and the workpiece is entirely processed by automatically circulating and rotating in this manner. Alternatively, it is possible to connect a large number of the object stands 30 to assemble the automatic conversion device of the object stand 30. The holding arm 20 and the table 30 are all connected to the hydraulic and electric control devices 40 and 50.

The hydraulic control device 40 is provided between the lathe body 10 and the table 30, and controls the operations of the hydraulic chuck 14, the blade holder 17, the holding arm 20, the table 30, and the like. .. The electric control device 50 is generally provided on the cutting side of the lathe body 10 so as to facilitate the simulated execution and correction of designed program data, and includes an operation panel 51 and a screen display 52. Thus, a number of different program data relating to the workpiece to be machined can be input, and internal control signals are connected to each of the above member devices. The entire mechanism assembled as described above has 90 ° rotation, 180 ° semi-circle rotation, clamping, and opening for the moving and fixing functions set by operating the program of the tool post and feed table of the CNC lathe. By connecting the holding arm 20 capable of performing such operations, the tool rest and the feed rest 160, 150 are orthogonal to the main spindle direction of the lathe body 10 and the main spindle according to the control of the servomotors 16 and 15 of the tool rest and the feed stand, respectively. The work can be moved accurately in the specified direction, and the workpiece can be automatically fed, processed, and fed.

As shown in FIGS. 5 and 6, in the workpiece carrying mechanism of the CNC lathe according to the present invention, before the CNC lathe advances the machining, the tool rest of the lathe and the feed platforms 160 and 150 set the program. The workpiece 33 is moved to a position where the workpiece 33 is to be clamped, and then the hydraulic grip 26 of the clamping arm 20 fixed to the tool rest and feed base is opened from the program control, and at the same time, the work tray 32 is also controlled by the program. When the workpiece 33 receives the rotation and ascends, and moves to a position where the workpiece 33 can be picked up by the hydraulic scoop 26, the hydraulic scoop 26 clamps the workpiece 33 and 180 ° from the program setting. When it rotates a half circle and then rotates 180 ° to reach a predetermined position, the holding arm 20 pivots downward 90 ° according to the set program and the setting position (the hydraulic swash 26 shown in FIG. 5 hangs downward). Position), the tool rest of the lathe body 10 and the feeds 160, 150 are moved by the set program, and the workpiece 33 of the clamping arm 20 can be clamped by the hydraulic chuck 14 of the lathe spindle 13. After moving to the position, the hydraulic chuck 14 of the lathe spindle 13 clamps the workpiece 33 firmly under the control of the program.

Subsequently, the hydraulic engraving 26 of the holding arm 20 is opened from the action of the set program, and at this time, the tool rest, the feed base, and the feed bases 160 and 150 are also controlled by the program so that the holding arm 20 is the original. After moving to a position where it can be returned to the point, the holding arms 20 of the tool rest and the feed rests 160 and 150 are operated under the control of a program to return to the original position.

Then, after the holding arm 20 fixed to the tool rest and the feed bases 160, 150 is operated from the set program and returned to the original position, the spindle 13 receives a program command. At the same time, the blade of the blade holder 17, which is rotated and fixed to the upper surface of the tool rest 160, performs a cutting process on the "workpiece 33" according to a command of the program. At this time, the work tray 32 is rotated by the set program. The processed product 33 'is moved to a position where it can be left in the storage column 34'. That is, when the processed product 33 'is delivered, the spindle 13 stops rotating according to the setting of the program, and at this time, the tool rest and the feed rests 160 and 150 move to the position where the clamping arm 20 is about to operate from the instruction of the program. Then, the holding arm 20 fixed to the turret and the feed bar 160, 150 receives a command from the program to rotate 180 ° and a half turn to reach the position set by the program, and further sets the command by another program. When the tool rests by 90 ° and reaches the set position, the tool rest of the lathe body 10 and the feed stands 160, 150 are moved by the setting of the program, and are fixed to the tool rest, the feed stands 160, 150. The hydraulic clamp 26 of the clamping arm 20 is moved to a position where the machined product 33 'after machining can be clamped. After the clamping arm 20 receives the command of the set program and moves the hydraulic grove 26 to a position where the machined product 33 ′ which has been machined can be clamped, the hydraulic grinder 26 is moved to the hydraulic chuck 14 by the set program. The clamped work product 33 'is picked up. At this time, the hydraulic chuck 14 of the spindle 13 opens according to the command of the program, and then the tool rest and the feed platforms 160, 150 move the clamping arm 20 halfway from the command of the program. Move to a setting position where you can rotate in a circle.

As described above, the present invention is a mechanism for inputting a program to set the number of “workpieces 33” and automatically circulating the feeding, machining, and feeding operations again. This is not a defect such as the tool rest of the lathe body and the feed stands 160 and 150, which are simply provided with the function of cutting, and which feed the workpiece 33 or the machined product 33 'by the independently arranged clamping mechanism. Furthermore, it is also possible to design an automatic transmission by connecting a large number of object stands 30 to promote an unmanned work system.
