[0002] The dual-spindle compound machine tool of the automated unit is a unit controller that logically processes programs specified by control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically processes parts according to the shape and size required by the drawing.
[0003] When processing the bearing workpiece, since the bearing is composed of an outer ring, an inner ring, a retaining frame and a ball, the outer ring and the inner ring are collectively referred to as a ferrule. The ferrule is formed by casting and forging, and then turned to become a finished product. At present, the turning of the ferrule is generally completed by a CNC lathe, but when processing the outer ring of the ferrule, it is generally necessary to perform two processes. First, one end of the ferrule is clamped on the rotating spindle of a CNC lathe, and the outer wall of the other end of the ferrule is turned. Then it flows into the next CNC lathe, and then the ferrule is clamped on the rotating spindle of the next CNC lathe, and the outer wall of the unprocessed end and the inner wall of the ferrule are turned. However, this method requires two CNC lathes, which is costly and will occupy a large space in the workshop. Summary of the invention

[0028] In actual operation, when this device is used, before processing the workpiece, the workpiece needs to be transported to one side of the drill bit 43. At this time, the workpiece can be placed between the two clamping blocks 513, and the connecting plate 512 is moved so that the connecting plate 512 drives the second T-shaped plate 5106 to slide in the second T-shaped groove 514. After the two clamping blocks 513 firmly clamp the two ends of the workpiece, the slide plate 517 is moved so that the slide plate 517 slides in the slide groove 518. At the same time, the slide plate 517 can drive the telescopic plate 516 to be inserted into the limiting groove 5104. In the later stage, it is only necessary to move the locking block 5101 so that the locking block 5101 and the hinge block 519 are hinged and both are in a folded state. At the same time, the locking block 5101 can drive the clamping block 5105 to be clamped in the clamping groove 5102, and the motor 527 is started again.

When the electric push rod 42 is started, the operation of the electric push rod 42 can drive the top block 44. The top block 44 can drive the second support block 48 to move out of the rectangular groove 49, while the second support block 48 can also drive the first T-shaped plate 47 to slide in the first T-shaped groove 46. On the other hand, the top block 44 can drive the drill bit 43 to perform processing operations on the workpiece. When processing the workpiece, debris will be generated. At this time, the debris will fall into the collection box 78 through the long groove 77. Later, it is only necessary to move the third T-shaped plate 71 so that the third T-shaped plate 71 moves in the third T-shaped slot 72. At the same time, the third T-shaped plate 71 can also drive the inserting plate 74 to move out of the slot 75, and the collection box 78 can directly drive the fourth T-shaped plate 76 to slide out of the fourth T-shaped slot 79.
