DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: An automatic flipping robot arm for a micro-arc electrophoresis production line of an electric tool comprises a base 1 and a connecting frame 11, wherein a motor 12 is fixedly connected inside the connecting frame 11, a rotating shaft 23 is fixedly connected at the output end of the motor 12, a bevel gear 14 is fixedly connected at the other end of the rotating shaft 23, a positioning plate 13 is fixedly connected inside the connecting frame 11, and the rotating shaft 23 is rotatably connected in the positioning plate 13, a top plate 15 is fixedly connected at the top of the connecting frame 11, mounting plates 16 are fixedly connected at the bottom of both sides of the top plate 15, a bidirectional threaded rod 17 is rotatably connected inside the mounting plate 16, a bevel gear 22 is fixedly connected at the middle of the bidirectional threaded rod 17, and the bevel gear 22 is meshed with the bevel gear 14, connecting blocks 18 are threadedly connected at both ends of the bidirectional threaded rod 17, a clamping plate 19 is fixedly connected to the top of the connecting block 18, an inner groove 20 is provided inside the top plate 15, and the connecting block 18 is slidably connected in the inner groove 20.

[0026] The start of the motor 12 causes the rotating shaft 23 to start rotating. The movement of the rotating shaft 23 drives a bevel gear 14 to start self-rotation. At the same time, the function of the positioning plate 13 is to fix and support the rotating shaft 23 to ensure that it remains stable during the rotation process. The self-rotation of the bevel gear 14 will further drive another bevel gear 22 and the internal bidirectional threaded rod 17 to start self-rotation. The self-rotation of the bidirectional threaded rod 17 will cause the reverse movement of the connecting blocks 18 at both ends. The movement of the connecting block 18 will drive the clamping plate 19 to move accordingly. The design of the inner groove 20 limits the direction of the clamping plate 19 to ensure that it maintains a consistent direction when moving. The workpiece can be clamped and grasped by the movement of the clamping plate 19. This coordinated sequence of actions enables the device to quickly and accurately grasp different workpieces, improving production efficiency and automation.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that, an electric hydraulic rod 2 is fixedly connected to the top of the base 1, a connecting plate 3 is fixedly connected to the output end of the electric hydraulic rod 2, a fixed block 7 is fixedly connected to the top of the base 1, a slide groove 8 is provided inside the fixed block 7, a rack 5 is arranged on the top of the base 1, the rack 5 is fixedly connected to the connecting plate 3 through a latch 4, a slider 6 is fixedly connected to the bottom of the rack 5, and the slider 6 corresponds to the slide groove 8, the slider 6 is slidably connected in the slide groove 8, a pair of fixed frames 9 are fixedly connected to the top of the base 1, a rotating column 21 is rotatably connected between the fixed frames 9 on both sides, a gear 10 is fixedly connected to the outer wall of one end of the rotating column 21, and the gear 10 is meshed with the rack 5, and at the same time, a connecting frame 11 is fixedly connected to the outer wall of the rotating column 21.

[0028] The electric hydraulic rod 2 is fixedly connected to the top of the starting base 1, and the electric hydraulic rod 2 pushes the rack 5 on the connecting plate 3 to move forward. During this movement, the advancement of the rack 5 will drive the gear 10 to start rotating. At the same time, the movement of the rack 5 is ensured to maintain the same direction by limiting the slider 6 in the slide groove 8 of the fixed block 7. The rotation of the gear 10 will also cause the rotating column 21 fixed thereon to start rotating inside the fixed frame 9. The rotation of this rotating column 21 will drive the top plate 15 on the connecting frame 11 to start rotating. This series of movement synergy enables the components on the connecting plate 3 to move in a predetermined manner, providing the necessary power and positioning for subsequent processes.

[0029] During operation, when the staff needs to use the mechanical arm to reverse the workpiece of the micro-arc electrophoresis production line, the electric hydraulic rod 2 is fixedly connected to the top of the starting base 1. Under the action of the electric hydraulic rod 2, the rack 5 on the connecting plate 3 is pushed forward. When the rack 5 moves forward, it will drive the gear 10 to rotate. When the rack 5 moves, it will be limited in the slide groove 8 in the fixed block 7 by the slider 6, so that the rack 5 maintains the same direction when moving. When the gear 10 rotates, it will drive the rotating column 21 to rotate inside the fixed frame 9. At this time, the rotation of the rotating column 21 will drive the top plate 15 on the connecting frame 11 to rotate. When the top plate 15 rotates to one side horizontally, the motor 12 inside the connecting frame 11 is started. When the motor 12 is started, it will drive the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it will drive the bevel gear 14 to rotate. At the same time, the positioning plate 13 plays the role of limiting the support of the rotating shaft 23. When the bevel gear 14 rotates, it will drive the bevel gear 2 22 and the internal two-way threaded rod 17 to rotate. When the two-way threaded rod 17 rotates, it will drive the connecting blocks 18 at both ends to move in the opposite direction. When the connecting block 18 moves, it will drive the clamping plate 19 to move, and through the inner groove 20 to limit, the clamping plate 19 keeps the same direction when moving. The movement of the clamping plates 19 on both sides will clamp and grab the workpiece, and the effect of quickly grabbing different workpieces is achieved through the cooperation between them. After grabbing, one side of the workpiece is processed first. After the processing is completed, the electric hydraulic rod 2 is started in the reverse direction, which will drive the connecting frame 11 on the rotating column 21 to rotate to the other side, thereby driving the workpiece to rotate to the other side for turning over. Through their cooperation, the work efficiency is greatly improved.
