Driven to achieve rotation, the first disc 104 is provided with an arc groove 1042 that facilitates the movement of the limiting rod 110, one end of the arc groove 1042 is close to the center of the first disc 104, and the other end is close to the edge of the first disc 104, and the top surface of the first disc 104 is provided with a top block 111, the top block 111 is in a "human" shape, and three straight grooves 1111 are provided on the top block 111, and the straight grooves 1111 are sleeved on the limiting rod 110, and the circular workpiece is placed on the top surface of the top block 111, and one or more can be stacked together, and the top block 111 is driven by the third driving component to achieve up and down sliding.

[0029] Furthermore, a positioning groove 1041 is provided on the first disc 104, and a U-shaped block 105 matching the positioning groove 1041 is fixedly connected to the bottom surface of the annular block 103, so that the loading fixture cannot rotate on its own, and the loading fixture can be fixed in the horizontal direction; this device is provided with two sets, when in use, one set is used for the unloading machine tool in workshop No. 1, and the other set is used for the loading machine tool in workshop No. 2. The specific operation is to first use the unloading machine tool in workshop No. 1 to stack the circular workpieces together, place the circular workpieces on the top surface of the top block 111, and one or more stacks can be placed together, and then through the second drive component The incomplete gear 308 is driven to rotate, and then the incomplete gear 308 drives the gear ring 302 to rotate, and then the gear ring 302 drives the first gear 301 to rotate through meshing transmission, and then the first gear 301 drives the rotating shaft 108 to rotate, and then the rotating shaft 108 drives the connecting rod 109 to rotate, and then the connecting rod 109 drives the limiting rod 110 to move, and then the limiting rod 110 is guided by the arc groove 1042 to approach each other toward the center of the first disc 104, so as to adapt to different diameters of circular workpieces, and at the same time, the limiting rod 110 can also move the circular workpiece with the first disc 104. The center points of the disks 104 are aligned. If the circular workpieces are stacked together, the limit rods 110 can also tidy up the stacked circular workpieces and prevent the circular workpieces from shifting during loading. In this way, the circular workpieces are placed on the loading jig to complete the operation of placing the circular workpieces. Then, the loaded loading jig is transported to the loading machine tool in the No. 2 workshop by a manipulator or a manual handling device, the positioning groove 1041 is aligned with the U-shaped block 105, and the loaded loading jig is directly placed into the circular groove 1021. Since the inner diameter of the annular block 103 is provided with a step groove 1031, it can Directly place the loading fixture into the circular groove 1021, and then drive the top block 111 through the third driving component, so that the top block 111 slides upward, and then the top block 111 drives the circular workpiece to move upward, and then the top block 111 can drive the circular workpiece to move to the top of the limit rod 110 so that the next process can be automatically loaded. After the loading of the circular workpiece in one of the circular grooves 1021 is completed, start the first motor 201, and then the output shaft of the first motor 201 drives the rotating shaft 202 to rotate, and then the rotating shaft 202 drives the turntable 102 to rotate, so that continuous loading can be achieved.

[0030] Furthermore, the loading jig also includes a magnetic spreader 601, and the magnetic spreader 601 is installed on the top of the limit rod 110. When the top block 111 drives the circular workpiece to move to the top of the limit rod 110, the magnetic spreader 601 can adsorb the circular workpiece through magnetic force and spread the circular workpiece in the process. This can avoid the phenomenon of circular workpieces sticking together, thereby improving the efficiency of the loading process.

[0031] Furthermore, the feeding jig also includes a locking assembly for locking the incomplete gear 308, the locking assembly includes a concave block 501, a wedge block 502, an elastic member 503, a fixing pin 504 and a fixing plate 505, the bottom surface of the first disc 104 is fixedly connected with the concave block 501, the concave block 501 is slidably connected with the wedge block 502, the wedge block 502 is made of rubber, and the bottom surface of the wedge block 502 is coated with a high-friction lubricant, an elastic member 503 is arranged between the wedge block 502 and the concave block 501, and the elastic member 503 is specifically a spring. Initially, the elastic member 503 is compressed, and the bottom surface of the wedge block 502 is fixedly connected with the fixing pin 504. The fixed plate 505 is provided with a movable groove 5051 for the movement of the U-shaped block 105, and a fixing pin 504 is fixedly connected in the movable groove 5051. The U-shaped block 105 is provided with an inclined surface 1051 matching with the fixing pin 504. The bottom surface of the incomplete gear 308 and the top surface of the second disc 107 are both provided with meshing teeth 506 for locking the incomplete gear 308. Specifically: when the loading fixture with loaded materials is transported to the loading machine tool in the No. 2 workshop by a robot or a manual transport device, a locking assembly is designed to prevent the incomplete gear 308 from rotating and causing the limit rod 110 to move. Since the incomplete gear 308 is connected to the outer wall of the gear ring 302 by a sliding key, when the feeding jig moves upward, the incomplete gear 308 will move downward under the influence of gravity until it contacts the top surface of the second disc 107, so that the meshing teeth 506 on the bottom surface of the incomplete gear 308 mesh with the meshing teeth 506 on the top surface of the second disc 107, thereby preventing the incomplete gear 308 from rotating, and thereby preventing the limit rod 110 from moving. At the same time, since the U-shaped block 105 no longer restricts the fixing plate 505, the elastic member 503 is reset, thereby driving the wedge block 502 to move in the direction of the incomplete gear 308, and then the bottom surface of the wedge block 502 is meshed with the incomplete gear 308. 08, so it can prevent the incomplete gear 308 from moving up and down during transportation. When placing the loading jig, that is, placing it on the loading machine in workshop No. 2, align the positioning groove 1041 with the U-shaped block 105, and directly put the loaded loading jig into the circular groove 1021. Since the U-shaped block 105 is provided with an inclined surface 1051 that cooperates with the fixing pin 504, the fixing pin 504, under the action of the U-shaped block 105, drives the fixing plate 505 and the wedge block 502 to move away from the incomplete gear 308, and then the wedge block 502 squeezes the elastic member 503, so that the elastic member 503 stores elastic potential energy, thereby completing the transfer work, and the operation is simple and convenient.

[0032] Specifically, the second driving assembly includes a driving box 303, a large gear 307, a small gear 306, a second motor 304 and a second gear 305.

The large gear 307 and the small gear 306 are both sleeved on the rotating shaft 202, and the incomplete gear 308 is meshed with the large gear 307. It also includes a baffle 604, the bottom surface of the large gear 307 is fixedly connected to the baffle 604, and the top surface of the baffle 604 contacts the bottom surface of the incomplete gear 308, so that a gap is set between the incomplete gear 308 and the top surface of the second disk 107; Specifically: start the second motor 304, the output shaft of the second motor 304 drives the second gear 305 to rotate, and then the second gear 305 drives the small gear 306 to rotate through meshing transmission, and then the small gear 306 drives the large gear 307 to rotate, and the large gear 307 drives the incomplete gear 308 to rotate through meshing transmission, so that the limit rod 110 can be moved to align the circular workpiece with the center point of the first disc 104. At the same time, due to the provision of the baffle 604, when the feeding fixture is placed, the baffle 604 will support the incomplete gear 308 upwards, so that the incomplete gear 308 and the top surface of the second disc 107 are set with a gap, so that the meshing teeth 506 on the bottom surface of the incomplete gear 308 and the meshing teeth 506 on the top surface of the second disc 107 are separated from each other, and when the feeding fixture is lifted, the incomplete gear 308 will slide downward, and cooperate with the wedge block 502 and the meshing teeth 506 to achieve locking and limiting.

[0033] Specifically, the third driving assembly includes a mounting seat 401 and an electric telescopic rod 402.
