Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a flipping and positioning device for machining and inspecting mechanical parts, which can solve the problem that commonly used flipping and positioning devices in the current field of machining and inspecting mechanical parts have significant limitations in their limiting design when performing the clamping and flipping operation. Due to the lack of an effective and stable limiting structure, mechanical parts are very easy to detach from the clamping device during the flipping process, which may not only cause damage to the parts, but also cause equipment failure, and even threaten the safety of operators, seriously affecting the stability of the machining and inspection process and production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a flipping and positioning device for processing and inspecting mechanical parts, which adopts the following technical solution: it includes a platform, and a clamping and positioning component is provided on the top of the platform;

[0007] The clamping and positioning assembly includes a robotic arm. A fixed base is fixedly mounted at the rear end of the robotic arm. A bidirectional lead screw is rotatably connected between the inner walls of the two sides of the fixed base. Both ends of the bidirectional lead screw are threadedly connected to sliders. A clamping arm is fixedly mounted on the rear side of each slider. Four adjustment ports are equally spaced from front to back on the surface of the two clamping arms. An adjustment rod is inserted into each adjustment port. One end of each adjustment rod is fixedly provided with a threaded wire, and each adjustment rod is fastened to the adjustment port by a corresponding bolt. The other end of each adjustment rod is fixedly provided with a connection port, and a suction cup is fixedly provided at the end of each connection port away from the adjustment rod.

[0008] Optionally, a connecting plate is fixedly provided on the side of each of the two clamping arms that is far apart from each other, and a vacuum generator is fixedly provided on the top of each of the two connecting plates by bolts. The top output ends of the two vacuum generators are respectively connected to the corresponding connecting ports through four connecting pipes.

[0009] Optionally, a motor is fixedly mounted on one side of the fixed base, and the output end of the motor is fixedly connected to one end of the bidirectional lead screw through the fixed base.

[0010] Optionally, a first support base and a second support base are fixedly provided at both ends of the top of the platform, and a rotating shaft is rotatably connected between the first support base and the second support base. The robotic arm is fixedly mounted outside the rotating shaft by a mounting base.

[0012] Optionally, one end of the rotating shaft extends to the outside of the first support base, and a gear is fixedly installed at one end of the rotating shaft. The gear meshes with a rack, and two conveyor belts with the same conveying direction are provided on both the front and rear sides of the platform.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By driving two sliders with a bidirectional lead screw, the clamping arms move towards or away from each other, achieving initial clamping and positioning of mechanical parts. Simultaneously, the adjusting rod, in conjunction with the adjusting port, allows for flexible adjustment of the suction cup spacing according to the part size, enabling the suction cups to precisely conform to the surfaces of mechanical parts of different specifications. Combined with a vacuum generator connected to the connecting port via a connecting pipe, the negative pressure principle enhances the suction force of the suction cups on the parts, forming a multi-level, multi-directional stable clamping structure.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0022] Example 1, refer to Figure 1-4In this embodiment, to address the significant limitation design flaws in commonly used flipping and positioning devices in the current field of mechanical parts processing and inspection, which have significant limitations when performing parts clamping and flipping operations, this invention discloses a flipping and positioning device for mechanical parts processing and inspection. Due to the lack of an effective and stable limiting structure, mechanical parts are prone to detaching from the clamping device during the flipping process, potentially causing damage to the parts, equipment malfunctions, and even threatening operator safety. This severely impacts the stability of the processing and inspection process and production efficiency.

[0023] Includes a platform 1, with a clamping and positioning component located on the top of the platform 1;

[0024] The clamping and positioning assembly includes a robotic arm 2. A fixed base 3 is fixedly installed at the rear end of the robotic arm 2. A bidirectional lead screw 4 is rotatably connected between the inner walls of the two sides of the fixed base 3. A slider 5 is threadedly connected to both ends of the bidirectional lead screw 4. A clamping arm 6 is fixedly installed on the rear side of each slider 5. Four adjustment ports 7 are opened at equal intervals from front to back on the surface of the two clamping arms 6. An adjustment rod 8 is inserted into each adjustment port 7. A threaded wire 9 is fixedly installed at one end of each adjustment rod 8. Each adjustment rod 8 is fastened to the adjustment port 7 by a corresponding bolt. A connection port 10 is fixedly installed at the other end of each adjustment rod 8. A suction cup 11 is fixedly installed at the end of each connection port 10 away from the adjustment rod 8.

[0025] Specifically, after the operator places the mechanical parts in a suitable position between the two clamping arms 6, the external drive source is activated to rotate the bidirectional lead screw 4. Since the threads at both ends of the bidirectional lead screw 4 rotate in opposite directions, the rotation causes the sliders 5 at both ends to move towards or away from each other along the bidirectional lead screw 4, thereby moving the two clamping arms 6 closer or further apart, achieving initial clamping and fixing of mechanical parts of different sizes. When it is necessary to adjust the position of the suction cup 11 to accommodate different adsorption points of the mechanical parts, the bolt on the adjusting rod 8 can be loosened, and the adjusting rod 8 can be moved to a suitable position in the front-back direction within the adjusting port 7. Then, the bolt is tightened, and the adjusting rod 8 is fixed using the fastening action of the bolt and the adjusting port 7, thus achieving flexible adjustment of the position of the suction cup 11. The suction cup 11 is connected to the adjusting rod 8 through the connecting port 10. When adsorbing mechanical parts, a negative pressure is formed inside the suction cup 11, tightly adsorbing the surface of the mechanical parts. Combined with the clamping force of the clamping arms 6, this achieves double stable fixing of the mechanical parts. The robotic arm 2 is connected to the bidirectional lead screw 4 via the fixed base 3. When it is necessary to flip the mechanical parts, the robotic arm 2 can drive the fixed base 3 and the bidirectional lead screw 4, slider 5, clamping arm 6, adjusting rod 8, connecting port 10 and suction cup 11 on the fixed base 3 to rotate together under the command of the control system. Since the suction cup 11 and clamping arm 6 provide a stable limit and fixation for the mechanical parts, it can effectively prevent the mechanical parts from falling off the clamping device during the flipping process, ensuring the stability of the mechanical parts during the processing and inspection flipping process, thereby ensuring the smooth progress of the processing and inspection process, improving production efficiency, and reducing equipment failure and safety risks caused by the falling off of parts.

[0026] A connecting plate 12 is fixedly installed on the side of each of the two clamping arms 6 that is far apart from each other, and a vacuum generator 13 is fixedly installed on the top of each of the two connecting plates 12 by bolts. The top output ends of the two vacuum generators 13 are respectively connected to the corresponding connecting ports 10 through four connecting pipes 14.

[0027] Specifically, the vacuum generator 13 is bolted to the connecting plate 12 for easy disassembly and maintenance. During operation, the vacuum generator 13 activates, drawing air from the suction cups 11 through the connecting pipes 14, creating a negative pressure inside the suction cups 11, thus tightly adsorbing the mechanical parts. The four connecting pipes 14 correspond to the four suction cups 11, ensuring that each suction cup 11 can stably generate suction, guaranteeing a firm grip on the mechanical parts and preventing them from detaching due to insufficient suction during flipping.

[0028] A motor 15 is fixedly mounted on one side of the fixed base 3, and the output end of the motor 15 is fixedly connected to one end of the bidirectional lead screw 4 through the fixed base 3.

[0029] Specifically, motor 15 is fixed to one side of the fixed base 3, providing power for the rotation of the bidirectional lead screw 4. When motor 15 starts, its output end drives the bidirectional lead screw 4 to rotate. Since the threads at both ends of the bidirectional lead screw 4 rotate in opposite directions, under the action of thread transmission, the two sliders 5 will move towards or away from each other along the bidirectional lead screw 4. By controlling the forward and reverse rotation and speed of motor 15, the positions of the two sliders 5 can be precisely adjusted, thereby driving the two clamping arms 6 to move closer or further away synchronously, realizing adaptive clamping of mechanical parts of different sizes and improving the versatility of the device.

[0030] A first support base 16 and a second support base 17 are fixedly installed at both ends of the top of the platform 1, and a rotating shaft 18 is rotatably connected between the first support base 16 and the second support base 17. The robotic arm 2 is fixedly installed outside the rotating shaft 18 through a mounting base 25.

[0031] Specifically, the first support base 16 and the second support base 17 provide a stable support structure for the rotating shaft 18, ensuring its smooth rotation. The robotic arm 2 is tightly connected to the rotating shaft 18 via the mounting base 25, allowing it to rotate synchronously with the rotation of the rotating shaft 18. This structural design lays the foundation for the flipping operation of mechanical parts. When it is necessary to inspect or process mechanical parts at different angles, the rotating shaft 18 drives the robotic arm 2 and the clamped parts to flip, thus meeting diverse production needs.

[0032] A cylinder 19 is fixedly installed at one end of the top of the platform 1. A drive rod 20 is fixedly connected to the output end of the front side of the cylinder 19. A rack 21 is fixedly installed at the front end of the drive rod 20. A limit groove 22 is fixedly installed on the top of the platform 1. The rack 21 is slidably installed outside the limit groove 22.

[0033] Specifically, cylinder 19 serves as the power component. Upon receiving a control signal, the piston inside cylinder 19 moves linearly under gas pressure, pushing the front drive rod 20 forward or backward. The drive rod 20 drives the rack 21 at its front end to slide within the limiting groove 22. The limiting groove 22 guides and limits the rack 21, ensuring the linearity and stability of its movement and preventing it from deviating or wobbling during operation, thereby ensuring the accuracy and reliability of power transmission.

[0034] One end of the rotating shaft 18 extends to the outside of the first support base 16, and a gear 23 is fixedly installed at one end of the rotating shaft 18. The gear 23 meshes with the rack 21. Two conveyor belts 24 with the same conveying direction are provided on both the front and rear sides of the platform 1.

[0035] Specifically, the gear 23 at one end of the rotating shaft 18 meshes with the rack 21. When the rack 21 moves in a linear reciprocating motion under the drive of the cylinder 19, it drives the gear 23 to rotate, thereby causing the rotating shaft 18 to rotate and realizing the flipping action of the robotic arm 2. The conveyor belts 24 on the front and rear sides of the platform 1 are used for conveying mechanical parts, transporting the parts to be inspected or processed to the area below the clamping and positioning assembly. After the mechanical parts have completed the flipping operation, they are then transported to the subsequent processing or inspection station, realizing the automated connection of the entire processing and inspection process and improving production efficiency.

[0036] The specific working principle is as follows: When the mechanical parts are conveyed to the bottom of the device via the conveyor belt 24, the motor 15 starts, driving the bidirectional lead screw 4 to rotate, causing the two sliders 5 to move towards each other along the bidirectional lead screw 4, thereby driving the two clamping arms 6 to approach the mechanical parts. When the clamping arms 6 move to the appropriate position, the adjusting rod 8 adjusts its position in the adjusting port 7 and is tightened by bolts, so that the suction cup 11 can fit against the appropriate position on the surface of the mechanical parts. At this time, the vacuum generator 13 starts, and the air in the suction cup 11 is extracted through the connecting pipe 14 to form a vacuum, so that the suction cup 11 tightly adheres to the mechanical parts, completing the clamping operation. Subsequently, the cylinder 19 receives a signal, and the internal piston pushes the drive rod 20 under the action of compressed air. The drive rod 20 drives the rack 21 to move forward in the limiting slide groove 22. Since the gear 23 meshes with the rack 21, the linear motion of the rack 21 drives the gear 23 to rotate, which in turn causes the rotating shaft 18 to rotate, and the mechanical arm 2 mounted on the rotating shaft 18 flips accordingly. By controlling the extension and retraction length and movement speed of cylinder 19, the rotation angle and speed of gear 23 can be precisely controlled, thereby achieving precise control of the flipping angle and speed of robotic arm 2, meeting the requirements for flipping angle and speed during the processing and inspection of different mechanical parts. After the mechanical part completes the flipping operation, vacuum generator 13 stops working, the vacuum state in suction cup 11 is released, and the mechanical part separates from suction cup 11. Motor 15 restarts, controlling the bidirectional lead screw 4 to reverse, causing clamping arm 6 to open, and the mechanical part continues to be transported to the next processing and inspection station via conveyor belt 24, completing the entire flipping and positioning operation process for mechanical part processing and inspection. Through the coordinated work of its components, this device effectively solves the defects in the limit design of existing flipping and positioning devices, improves the stability and safety of mechanical parts during the flipping process, and ensures the efficient execution of the processing and inspection process.

The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor and cylinder will not be explained in detail.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
