[0028] By Figures 1 - 8Provided is a blanking device for a double-spindle turning and milling compound machine according to the present utility model, which includes a movable blanking table 1. Two sliders 11 at the bottom of the movable blanking table 1 slide in the slideways on the top surface of the machine tool 2. A double-spindle turning and milling machine frame 21 is installed on both sides of the machine tool 2. The support plate at the top of the movable blanking table 1 is rotatably connected to both sides of one end of the processing table 12. The top of the movable blanking table 1 and the bottom end of the processing table 12 are rotatably connected to both ends of two hydraulic rods 13. A second guard plate 15 is jointly installed between two first guard plates 14 symmetrically fixed on the top of the processing table 12. The machine tool 2 is provided with a first blanking inclined plate 4 and a second blanking inclined plate 5 with the same inclination on both sides of the processing table 12, and the height of the first blanking inclined plate 4 is higher than that of the second blanking inclined plate 5. Both sides of the processing table 12 can be rotated to fit the side walls of the first blanking inclined plate 4 and the second blanking inclined plate 5, and at this time, the surfaces of the three are on the same inclined plane. Two conveyor belts 3 are provided on both sides of the machine tool 2 at the position of the movable blanking table 1. The side of the second guard plate 15 is close to the second blanking inclined plate 5.

[0029] Through the above structural design, the blanking device is composed of the first blanking inclined plate 4, the second blanking inclined plate 5, two conveyor belts 3 and the components installed on the top of the movable blanking table 1. In terms of design, the upper end of the inclined surface of the second blanking inclined plate 5 is slightly lower than the conveying surface of the conveyor belt 3 and is located on one side of it, while the lower end of the inclined surface of the second blanking inclined plate 5 is at a position above the conveyor belt 3. Then during operation, the hydraulic rods 13 are started. The output ends of the hydraulic rods 13 are rotatably connected to the bottom end of the processing table 12. Then when the main body ends of the hydraulic rods 13 rotate on the top of the movable blanking table 1, the output ends will also rotate while extending, thereby causing the processing table 12 to rotate away from the rotation point of the hydraulic rods 13, so that both sides of the processing table 12 are rotated to fit the side walls of the first blanking inclined plate 4 and the second blanking inclined plate 5, and the surfaces of the three are on the same inclined plane. Then a lifting conveyor can be installed on the side of the conveyor belt 3 on one side of the first blanking inclined plate 4, which is more labor-saving for placement. The workpiece is transported to the conveyor belt 3 by the lifting conveyor and then transported to the first blanking inclined plate 4. The workpiece slides down to the processing table 12 through the inclined plane and is intercepted by the second guard plate 15 jointly installed between the first guard plates 14, so that it cannot slide onto the second blanking inclined plate 5. Then the processing table 12 is restored to horizontal, and it slides to the position below the double-spindle turning and milling machine frame 21 through the sliders 11 for processing. After processing, it is reset. At this time, the second guard plate 15 is removed, and the processing table 12 is tilted again. The workpiece can automatically slide onto the second blanking inclined plate 5 and finally fall onto the conveyor belt 3 below the second blanking inclined plate 5 and be transported away. Then the second guard plate 15 is installed and the cycle is repeated, realizing semi-automatic double blanking operation, effectively improving the work efficiency, and the overall operation is safer and more stable. It should be noted that when the processing table 12 is horizontal, the hydraulic rods 13 are still in an inclined state.

[0030] On one side of the processing table 12, a convex block 16 is fixed, and the convex block 16 is in contact with the bottom surface of the first blanking inclined plate 4. At this time, the processing table 12 is aligned with the surfaces of the first blanking inclined plate 4 and the second blanking inclined plate 5. Rubber pads 7 are adhered to the sides of the first blanking inclined plate 4 and the second blanking inclined plate 5, and the rubber pads 7 are in close contact with both sides of the movable blanking table 1. On both sides of the top of the first blanking inclined plate 4 and the second blanking inclined plate 5, two third guard plates 6 are symmetrically fixed respectively, and the distance between the two third guard plates 6 is the same as the distance between the first guard plates 14. Both sides of the first guard plates 14 are close to one side of the third guard plates 6. Insertion slides 111 are provided on both sides of the second guard plate 15, and the insertion slides 111 are inserted from the sockets provided at the inner tops of the two first guard plates 14. A handle is provided on the top of the second guard plate 15, and an elastic silica gel pad 110 is adhered to the surface of the second guard plate 15 close to the first blanking inclined plate 4.

[0031] In the further optimization of the blanking device, the convex block 16 can play a limiting role. When the convex block 16 is in contact with the bottom surface of the first blanking inclined plate 4, the processing table 12 cannot rotate, and the planes of the three are just aligned. A touch shutdown system can be configured to make the hydraulic rod 13 automatically close when the convex block 16 touches the first blanking inclined plate 4, which is very convenient. Moreover, when both sides of the processing table 12 are in contact with the side walls of the first blanking inclined plate 4 and the second blanking inclined plate 5 through rotation, collisions will inevitably occur. Therefore, the rubber pads 7 are designed. By using their own deformation ability, collisions can be avoided. The rubber pads 7 replace the first blanking inclined plate 4 and the second blanking inclined plate 5 to contact the processing table 12, avoiding the workpiece being stuck due to gaps. The second guard plate 15 can be quickly disassembled and assembled by pulling up or inserting through the design of the slides 111 on both sides. At the same time, the elastic silica gel pad 110 can play a buffering role when intercepting the workpiece. Finally, the third guard plates 6 can cooperate with the first guard plates 14 to block and protect the workpiece when it moves along the inclined plane, increasing stability.

[0032] Two support blocks 17 are symmetrically fixed at the bottom of the processing table 12. A rubber block 18 is fixed at the bottom of the support blocks 17. The support blocks 17 are designed at the bottom surface position of one end far from the rotation point of the processing table 12, and the rubber block 18 is in contact with the top surface of the movable blanking table 1 when the processing table 12 is in a horizontal position.

[0033] As described above, when the processing table 12 is in a horizontal position, the rubber block 18 at the bottom of the support blocks 17 is in contact with the top surface of the movable blanking table 1, which can then play a very good role in strengthening the support, avoiding the vibration force during processing from affecting the shaft connection points between the processing table 12, the movable blanking table 1, and the hydraulic rod 13, which is very practical.

[0034] A lead screw 22 is rotatably connected between two support plates on the top surface of the machine tool 2, and a motor 23 for driving the rotation of the lead screw 22 is installed on the top of the machine tool 2. The lead screw 22 is in threaded connection with a square block 19 welded to the bottom of the movable blanking table 1.

[0035] During the working process, the lead screw 22 is rotated by starting the motor 23, and then the square block 19 is driven to drive the movable blanking table 1 to move, so that the movable blanking table 1 can be conveniently driven to switch between the blanking area and the processing area, which is very convenient.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
