[0021] like Figure 1 and Figure 3 As shown, a workpiece flexible clamping automatic centering mechanism includes a base plate 1 and a processing table 3 located above the base plate 1, the base plate 1 and the processing table 3 are fixedly connected by two side plates 2, a placement seat 4 is fixedly connected to the middle of the upper surface of the processing table 3, a placement hole 5 is provided inside the placement seat 4, a circular hole matched with the placement hole 5 is provided inside the processing table 3, the circular hole is concentric with the placement hole 5, and the placement hole 5 is used for the workpiece to be processed.

[0022] like Figure 1 , Figure 2 and Figure 5As shown, a clamping mechanism for positioning the workpiece is arranged above the base plate 1, and the clamping mechanism includes a motor plate installed on the bottom surface of the processing table 3, a double-axis motor 6 is installed on one side of the motor plate, two output ends of the double-axis motor 6 are fixedly connected with threaded rods 7, and the ends of the two threaded rods 7 away from each other are rotatably installed inside the two side plates 2, the outer surfaces of the two threaded rods 7 are threadedly connected with threaded members 8, and movable plates 9 are fixedly installed on the two threaded members 8, and slides 10 are fixedly installed on the upper surfaces of the two movable plates 9. A first through groove for horizontal sliding of the slide 10 is provided inside the processing table 3, and the threads provided on the two threaded rods 7 are in opposite directions. When the double-axis motor 6 is started, the two threaded rods 7 can be driven to rotate at the same time, and the rotation of the two threaded rods 7 can drive the two threaded members 8 to move horizontally in opposite directions, and the movement of the threaded members 8 can drive the movable plate 9 and the slide 10 to move accordingly.

[0023] like Figure 5 As shown, the first right-angle plate 11 is fixedly installed on the sides of the two slides 10 that are close to each other, and the flexible clamping members 12 are fixedly installed on the sides of the two first right-angle plates 11 that are close to each other, and the two flexible clamping members 12 are respectively located on both sides of the placement seat 4, and a V-shaped groove is provided on the sides of the two flexible clamping members 12 that are close to each other. The movement of the slide 10 can drive the first right-angle plate 11 and the flexible clamping members 12 to move accordingly. By providing a V-shaped groove on the flexible clamping members 12, when the two flexible clamping members 12 move inward to clamp the workpiece, the workpiece can be centered at the same time. The flexible clamping members 12 are made of rubber material.

[0024] like Figure 1 , Figure 7 and Figure 8As shown, the conveying mechanism includes a conveying plate 27 located above the placement seat 4, a through hole 28 adapted to the placement hole 5 is opened inside the conveying plate 27, a third right-angle plate 29 is slidably arranged on the bottom surface of the conveying plate 27, a second support plate 30 is fixedly connected to the bottom surface of the conveying plate 27, the second support plate 30 and the third right-angle plate 29 are connected by a second spring 31, and the side of the third right-angle plate 29 away from the conveying plate 27 is slidably connected to the processing table 3, the conveying mechanism also includes a first conveying line 13 and a second conveying line 14, the first conveying line 13 is located above the conveying plate 27, The second conveyor line 14 is located on the upper surface of the processing table 3 and is flush with the placement seat 4. Two first baffles 43 are fixedly connected to the first conveyor line 13, and a second baffle 44 is fixedly connected to the upper surface of the conveying plate 27. The first conveyor line 13 is used to convey the workpiece before processing, and the second conveyor line 14 is used to transport the workpiece after processing. When the workpiece on the first conveyor line 13 falls onto the conveying plate 27, the two first baffles 43 can position the workpiece, and then drive the conveying plate 27 to move in the direction away from the placement seat 4. At this time, the workpiece is blocked by the first conveyor line 13 and will not The conveying plate 27 moves, and when the conveying plate 27 moves to the maximum extent, the workpiece will fall into the inside of the through hole 28. At this time, the second spring 31 will push the third right-angle plate 29 to move into the inside of the through hole 28, thereby blocking the workpiece to prevent the workpiece from falling completely from the conveying plate 27. When the conveying plate 27 is driven to move in the direction of the placement seat 4, the workpiece in the through hole 28 will be driven to move together. At this time, the first conveying line 13 can be started to make the next workpiece fall onto the conveying plate 27. When the third right-angle plate 29 moves to contact with the placement seat 4, the conveying plate 27 continues to move, which will cause the third right-angle plate 29 to move in contact with the placement seat 4. The plate 29 compresses the second spring 31. When the conveying plate 27 moves to the maximum extent in the direction of the placement seat 4, the third right-angle plate 29 will be completely removed from the bottom of the through hole 28. At this time, the workpiece in the through hole 28 will fall into the inside of the placement hole 5. The distance between the conveying plate 27 and the placement seat 4 is less than the length of the workpiece, so that the through hole 28 and the placement hole 5 can guide the workpiece, thereby ensuring that the workpiece can fall into the inside of the placement hole 5. A guide column 32 is fixedly connected to the back side of the third right-angle plate 29. The guide column 32 passes through the second support plate 30 and is slidably connected to the second support plate 30.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the conveying mechanism also includes a driving rod 15 rotatably installed between the two side plates 2, the outer surface of the driving rod 15 is fixedly connected to the second synchronous wheel 18, the outer surface of the threaded rod 7 is installed with a one-way bearing 16, the first synchronous wheel 17 is installed on the one-way bearing 16, and the first synchronous wheel 17 and the second synchronous wheel 18 are connected through a synchronous belt transmission. When the dual-axis motor 6 drives the two threaded rods 7 to rotate forward to clamp the workpiece, the threaded rod 7 will only drive the one-way bearing 16 to rotate, and the first synchronous wheel 17 will not rotate. When the dual-axis motor 6 drives the two threaded rods 7 to rotate in the opposite direction to control the reset of the two flexible clamping members 12, the threaded rod 7 will drive the first synchronous wheel 17, the second synchronous wheel 18 and the driving rod 15 to rotate accordingly.

[0026] like Figure 2 and Figure 6 As shown, a group of first support plates 22 are rotatably installed on the outer surface of the driving rod 15, and the bottom surface of the first support plate 22 is fixedly connected to the bottom plate 1, the outer surface of the driving rod 15 is threadedly connected to a threaded block 23, the upper surface of the threaded block 23 is fixedly connected to a first triangular block 24, the inside of the circular hole is slidably connected to a top plate 19, the bottom surface of the top plate 19 is fixedly connected to a second right-angle plate 20, and a second through groove for the second right-angle plate 20 to slide up and down is opened inside the processing table 3, the outer surface and bottom surface of the second right-angle plate 20 are respectively fixedly connected to a first spring 21 and a second triangular block 25 adapted to the first triangular block 24, and the other end of the first spring 21 is fixedly connected to the processing table 3, the inclined surface of the second triangular block 25 is fitted with the inclined surface of the first triangular block 24, the number of a group of first support plates 22 is two, the driving rod 15 is composed of a reciprocating screw between the two first support plates 22 and a round rod connected to both ends of the reciprocating screw, the round rods at both ends of the reciprocating screw are connected to the first support The support plate 22 is rotatably connected, so that when the driving rod 15 rotates, the reciprocating screw rod between the two first support plates 22 can drive the threaded block 23 to reciprocate between the two first support plates 22, and the movement of the threaded block 23 can drive the first triangular block 24 to move accordingly. When the first triangular block 24 moves to the left, it can squeeze the second triangular block 25 to move upward. The upward movement of the second triangular block 25 can drive the second right-angle plate 20 and the top plate 19 to move upward and compress the first spring 21. The upward movement of the top plate 19 can lift the workpiece inside the placement hole 5. When the top plate 19 completely pushes the workpiece out of the placement hole 5, the push plate 38 will move to contact the workpiece. When the threaded block 23 moves to the right, under the action of the first spring 21, the second triangular block 25 and the top plate 19 will move downward to reset. When the top plate 19 moves downward to reset, the third right-angle plate 29 will move away from the bottom of the through hole 28, so that the workpiece in the through hole 28 will fall into the placement hole 5.

[0027] like Figure 6As shown, a first baffle 26 is fixedly connected to one side of the first triangular block 24. By setting the first baffle 26, when the first triangular block 24 moves to the left side and is not in contact with the second triangular block 25, the first baffle 26 can block the second triangular block 25 to prevent it from falling. When the second triangular block 25 is about to contact with the first baffle 26, the push plate 38 also contacts with the workpiece, and the driving rod 15 continues to rotate. Through the driving rod 15, when the second triangular block 25 moves to the end of the first baffle 26, it will move in the reverse direction until the second triangular block 25 moves in the reverse direction to separate from the first baffle 26. At this time, the push plate 38 also pushes the workpiece to separate from the top plate 19.

[0028] like Figure 1 , Figure 2 and Figure 7 As shown, both sides of the conveying plate 27 are fixedly connected with fourth right-angle plates 33, the interior of the processing table 3 is provided with a third through groove for the fourth right-angle plates 33 to slide horizontally, the bottom surfaces of the two fourth right-angle plates 33 are fixedly connected with toothed plates 34, the outer surfaces of the two threaded rods 7 are fixedly connected with gears 35, the two gears 35 are respectively meshed with the two toothed plates 34, the outer surfaces of the two fourth right-angle plates 33 are fixedly connected with a plurality of third support plates 36 distributed up and down, and the upper and lower third support plates 36 are respectively in contact with the upper surface and the bottom surface of the processing table 3, the third support plates 36 are used to support the fourth right-angle plates 33 and the conveying plate 27, and lift them during movement. Stability, when the dual-axis motor 6 drives the two threaded rods 7 to rotate forward to clamp the workpiece, the threaded rod 7 can drive the gear 35 to rotate forward, and the forward rotation of the gear 35 can drive the toothed plate 34, the fourth right-angle plate 33 and the conveying plate 27 to move horizontally away from the placement seat 4 to prevent the workpiece from being blocked and affecting the processing of subsequent processing equipment. When the dual-axis motor 6 drives the two threaded rods 7 to rotate reversely to control the reset of the two flexible clamps 12, the threaded rod 7 can drive the gear 35 to rotate reversely, and the reverse rotation of the gear 35 can drive the toothed plate 34, the fourth right-angle plate 33 and the right-angle seat 37 to move horizontally toward the placement seat 4 to realize automatic placement of the workpiece.

[0029] like Figure 1 , Figure 7 , Fig. 9 and Fig.10As shown, the outer surface of the fourth right-angle plate 33 is fixedly connected to a right-angle seat 37, and a rotating shaft 40 is rotatably installed inside the right-angle seat 37. The outer surface of the rotating shaft 40 is fixedly connected to a push plate 38, and the top of the rotating shaft 40 is fixedly connected to a cylinder 39, and a torsion spring 41 is fixedly connected to the inside of the cylinder 39, and the other end of the torsion spring 41 is fixedly connected to the right-angle seat 37. One side of the gear 35 is fixedly connected to a second baffle 42 for blocking the push plate 38. The rotation of the push plate 38 can drive the torsion spring 41 to deform, and the second baffle 42 can block the push plate 38. Under the action of the second baffle 42, the two push plates 38 can form an eight-shaped push workpiece, thereby preventing the workpiece from deviating from the direction. When the push plate 38 is reset from front to back, it will be blocked by the workpiece and will rotate in the direction away from the second baffle 42. After passing through the workpiece, the torsion spring 41 will reset the push plate 38.

[0030] Working principle: When processing the workpiece, first start the dual-axis motor 6, so that the dual-axis motor 6 drives the two threaded rods 7 to rotate in the forward direction. The forward rotation of the two threaded rods 7 can drive the two flexible clamps 12 to move in the direction of the workpiece, so as to clamp the workpiece. At the same time, the forward rotation of the threaded rod 7 can also drive the gear 35 to rotate in the forward direction. The forward rotation of the gear 35 can drive the tooth plate 34, the fourth right-angle plate 33 and the conveying plate 27 to move horizontally in the direction away from the placement seat 4. When the conveying plate 27 moves to the maximum extent in the direction away from the placement seat 4, the flexible clamp 12 will move to just clamp the workpiece, and the workpiece on the conveying plate 27 will fall into the through hole 28. At this time, the third right-angle plate 29 under the conveying plate 27 will block the workpiece to prevent the workpiece from falling completely from the conveying plate 27.

[0031] After the processing of the workpiece is completed, the dual-axis motor 6 is started, so that the dual-axis motor 6 drives the two threaded rods 7 to rotate in the opposite direction. The reverse rotation of the threaded rod 7 can drive the gear 35, the first synchronous wheel 17, the second synchronous wheel 18 and the driving rod 15 to rotate in the opposite direction. The rotation of the driving rod 15 can drive the threaded block 23 to move back and forth between the two first support plates 22. The movement of the threaded block 23 can drive the first triangular block 24 to move accordingly. When the first triangular block 24 moves to the left, it can squeeze the second triangular block 25 to move upward. The upward movement of the second triangular block 25 can drive the second right-angle plate 20 and the top plate 19 to move upward and compress the first spring 21. The upward movement of the top plate 19 can lift the workpiece inside the placement hole 5. When the first triangular block 24 moves to the left and does not contact the second triangular block 25, the first baffle plate 26 can block the second triangular block 25 to prevent it from falling. The gear 35 rotates in the opposite direction to drive the toothed plate 34, the fourth right-angle plate 33 and the conveying plate 27 to move in the direction of the placement seat 4. The movement of the conveying plate 27 can drive the workpiece in the through hole 28 to move together. At this time, the first conveyor line 13 can be started to make the next workpiece fall onto the conveying plate 27. When the push plate 38 moves to contact the workpiece, the second triangular block 25 is about to contact the first baffle plate 26. The top plate 19 completely pushes the workpiece out of the placement hole 5. Then the conveying plate 27 continues to move to push the workpiece to the second conveyor line 14. When the conveying plate 27 continues to push the workpiece, the driving rod 15 first drives the first baffle plate 26 to move to the left, and returns to the right after reaching the appropriate position. During this period, the first baffle plate 26 has been blocking the second triangular block 25 to ensure that the top plate 19 is always flush with the placement seat 4 to facilitate the pushing of the workpiece. When the first baffle plate 26 returns to the point of being about to disengage from the second triangular block 25, the workpiece is just pushed away from the top plate 19, and at this time the third right-angle plate 29 also moves to contact the placement seat 4.

[0032] Then the conveying plate 27 continues to move, causing the third right-angle plate 29 to compress the second spring 31. At the same time, the threaded block 23 also drives the first triangular block 24 to continue to move to the right, causing the top plate 19 to fall. When the conveying plate 27 moves to the maximum extent in the direction of the placement seat 4, the workpiece is also pushed onto the second conveyor line 14, and then transported to the designated position by the second conveyor line 14. At the same time, the top plate 19 falls to the initial position under the action of the first spring 21. At this time, the third right-angle plate 29 will be completely removed from the bottom of the through hole 28, and the workpiece in the through hole 28 will fall into the inside of the placement hole 5. After that, the dual-axis motor 6 can be started to clamp the workpiece. By repeating the above steps, the automatic placement and clamping of the workpiece can be realized, thereby not only ensuring the processing efficiency but also reducing the production cost.
