[0012] This utility model proposes an avoidance structure 1000.

[0013] Please see Figure 1 and Figure 2In one embodiment of this utility model, the avoidance structure 1000 includes a mounting plate 1, a driving member 2, and a support block 3. The mounting plate 1 is provided with a track block 11, and the track block 11 has a track groove 12. One end of the support block 3 is provided with a cam follower 4, which is connected to the driving end of the driving member 2. The cam follower 4 is movably disposed in the track groove 12. The driving member 2 can drive the cam follower 4 to move the support block 3 along the track groove 12.

[0014] In this embodiment, it is understood that the avoidance structure 1000 can be applied to scenarios such as automated production lines and machining fixtures that require precise positioning and avoidance cooperation, and is not limited here. The mounting plate 1 is used to fix and support the entire avoidance structure 1000. The track block 11 and track groove 12 on the mounting plate 1 provide a precise guide path for the movement of the cam follower 4, ensuring that the cam follower 4 can move along the predetermined track groove 12, thereby achieving precise support and avoidance action of the support block 3. It is understood that the track block 11 can be set on the mounting plate 1 by bolt connection, welding, riveting, etc., or it can be connected to the mounting plate 1 by integral molding. The side wall of the track block 11 has a track groove 12 that penetrates its wall surface, and the shape and size of the track groove 12 are adapted to the size of the cam follower 4. One end of the support block 3 is fitted with the cam follower 4, combined with... Figure 3 It is understood that cam followers 4 are respectively installed at opposite ends of the support block 3, thereby providing stable support and control in two directions. This effectively reduces the tilting or offset of the support block 3 during movement, ensuring the stability of the support block 3 in support and avoidance actions. The cam follower 4 moves within the track groove 12, driven by the movement of the drive member 2. The interference fit (clearance ≤ 0.05 mm) between the cam follower 4 and the track groove 12 ensures the accuracy and reliability of the movement. The cam follower 4 uses a hardened steel roller (hardness HRC60±2). The drive member 2 provides power, driving the cam follower 4 to move along the track groove 12 through the movement of its drive end. The type of drive member 2 includes, but is not limited to, cylinders, motors, etc., with cylinders being preferred here. Figure 1 It should be noted that the avoidance structure 1000 provided by this utility model has three stages: In the support stage, the mounting plate 1 provides a stable mounting platform to ensure the fixation of the track block 11 and the driving component 2; the driving component 2 remains in its initial position; the support block 3 is positioned in the track groove 12 by the cam follower 4, providing a stable support surface. In the avoidance stage, the driving component 2 receives a signal and acts to push the support block 3, thereby pushing the cam follower 4 to move in the track groove 12 to achieve the avoidance action. In the reset stage, after the product leaves, the driving component 2 receives a signal and acts in the opposite direction, causing the cam follower 4 of the support block 3 to descend along the track groove 12 and return to the initial position of the support stage, completing the reset action.

[0015] The obstacle avoidance structure 1000 provided by this utility model adopts a combined design of mounting plate 1, track block 11, driving component 2, cam follower 4, and support block 3. Mounting plate 1 serves as the foundation of the entire obstacle avoidance structure 1000, providing a stable mounting platform for other components. Track block 11 is mounted on mounting plate 1 and has a track groove 12. The track groove 12 guides the movement trajectory of cam follower 4, thereby realizing the obstacle avoidance movement of support block 3. The driving end of driving component 2 is connected to cam follower 4, providing power to cam follower 4 to move along track groove 12. Cam follower 4 is movably mounted within track groove 12, tightly engaging with it to ensure accuracy and stability of movement. Support block 3 is connected to cam follower 4 and moves with cam follower 4, thereby supporting and adjusting the position of materials or other objects. This structural design allows the obstacle avoidance action of support block 3 to achieve complex obstacle avoidance paths based on the shape of track groove 12 and the driving method of driving component 2, improving the flexibility and adaptability of the mechanical system. Meanwhile, the cooperation between the cam follower 4 and the track groove 12 can effectively reduce friction and wear during the motion process, thereby improving the reliability and service life of the system.

[0016] In one embodiment of the present invention, the track groove 12 includes a first groove segment 121, a second groove segment 122 and a third groove segment 123 connected in sequence, wherein the end of the second groove segment 122 near the first groove segment 121 is lower than the end of the second groove segment 122 near the third groove segment 123.

[0017] In this embodiment, combined with Figure 3 and Figure 4 To provide motion accuracy, the trajectory groove 12 is configured as a combination of a first groove segment 121, a second groove segment 122, and a third groove segment 123. The first groove segment 121 is positioned lower than the third groove segment 123. The first groove segment 121 is closer to the drive component 2, while the third groove segment 123 is further away from the drive component 2. The first groove segment 121 is a gentle slope with a small incline, not exceeding 5 degrees, providing a stable support surface to ensure the stability of the support block 3 in its initial position. The second groove segment 122 is a transition zone, generally sloped, to achieve a smooth transition from the support stage to the avoidance stage. The third groove segment 123 is an avoidance zone with a large radius of curvature, such as greater than 50mm, ensuring that the support block 3 can quickly descend or rise to achieve the avoidance action. Understandably, to better adapt to the cam follower 4, the walls of the first groove segment 121 and the third groove segment 123 are curved, allowing the curved walls to better contact the cam follower 4.

[0018] It should be noted that the avoidance structure 1000 provided by this utility model has three stages: In the support stage, the mounting plate 1 provides a stable mounting platform to ensure the fixation of the track block 11 and the driving member 2; the driving member 2 remains in its initial position; the support block 3 is positioned in the track groove 12 by the cam follower 4, providing a stable support surface, at which time the cam follower 4 is limited to the first groove segment 121 of the track groove 12. In the avoidance stage, the driving member 2 receives a signal and acts to push the support block 3, thereby pushing the cam follower 4 to move in the track groove 12, that is, after passing through the second groove segment 122, the cam follower 4 is limited to the third groove segment 123 of the track groove 12, realizing the avoidance action. In the reset stage, after the product leaves, the driving member 2 receives a signal and acts in the opposite direction, causing the cam follower 4 of the support block 3 to descend along the track groove 12, returning to the initial position of the support stage, completing the reset action.

[0019] In one embodiment of the present invention, the connection between the first groove segment 121 and the second groove segment 122 is an arc transition, and the connection between the second groove segment 122 and the third groove segment 123 is an arc transition.

[0020] In this embodiment, combined with Figure 4 To achieve a smooth transition, the connection points between the first groove segment 121 and the second groove segment 122, as well as the connection points between the second groove segment 122 and the third groove segment 123, all employ arc transitions. This ensures a smooth transition for the cam follower 4 between different groove segments, reducing impact and vibration during operation. In the transition area between adjacent groove segments, the arc transition provides a smoother contact surface, reducing wear caused by abrupt changes.

[0021] In one embodiment of this utility model, the mounting plate 1 is provided with a guide rail 13, the driving end of the driving component 2 is connected to a connecting rod 21, and a slider 31 is provided below the support block 3. The slider 31 is slidably connected to the guide rail 13 and connected to the connecting rod 21.

[0022] In this embodiment, combined with Figure 3The guide rail 13 provides a fixed motion trajectory for the slider 31. When the slider 31 slides on the guide rail 13, it is constrained by the guide rail 13 and can only move along the direction of the guide rail 13. This guiding effect can eliminate the degree of freedom of the slider 31 in other directions, ensuring the accuracy and stability of its movement. The driving end of the driving component 2 is connected to the slider 31 through the connecting rod 21. When the driving component 2 works, the force or torque it generates is transmitted to the slider 31 through the connecting rod 21, causing the slider 31 to move along the guide rail 13. It can be understood that the guide rail 13 is horizontally mounted on the mounting plate 1 and set along the driving direction of the driving component 2, so that the driving component 2 can drive the support block 3, thereby driving the cam follower 4 to move in the track groove 12. The guide rail 13 can be fixed to the mounting plate 1 by bolt connection, riveting connection, etc., and the support block 3 and the slider 31 can be connected by bolt connection, snap-fit, etc., which is not limited here.

[0023] In one embodiment of this utility model, the end of the connecting rod 21 away from the driving member 2 is provided with a buckle section 211, and the end of the slider 31 is provided with a slot 311, which engages with the buckle section 211.

[0024] In this embodiment, combined with Figure 3 To enable rapid disassembly and maintenance, the snap-fit ​​joint between the snap-fit ​​segment 211 and the slot 311 simplifies and expedites the connection between the connecting rod 21 and the slider 31, eliminating the need for complex tools or bolts and significantly improving installation efficiency. The snap-fit ​​segment 211 can be integrally formed or bolted together and positioned at the end of the connecting rod 21 furthest from the driving component 2. The snap-fit ​​segment 211 is L-shaped with a small, elastic hook at its tail end. The snap-fit ​​segment 211 typically possesses a certain degree of elasticity or deformability, allowing it to be inserted into the slot 311 during assembly and then locked in place by its elastic restoring force, preventing loosening. The shape and size of the slot 311 match the snap-fit ​​segment 211, providing sufficient space for insertion and sufficient friction and mechanical resistance to prevent it from dislodging.

[0025] In one embodiment of the present invention, a connecting block 33 is provided between the support block 3 and the slider 31, and a guide rod 34 is provided between the connecting block 33 and the support block 3. The guide rod 34 connects the connecting block 33 and the support block 3 respectively.

[0026] In this embodiment, combined with Figure 3The guide rod 34 effectively restricts the relative movement between the support block 3 and the connecting block 33, reducing swaying and vibration during movement and improving the stability of the entire device. The guide rod 34 connects the connecting block 33 and the support block 3, providing stable support for the support block 3 and ensuring that it does not shift or sway during movement. The cooperation between the guide rod 34 and the connecting block 33 further constrains the movement direction of the support block 3, ensuring it moves in a straight line and improving the accuracy and stability of the movement. It is understood that the number of guide rods 34 includes, but is not limited to, one, two, and four. Two guide rods 34 arranged in parallel can further improve the stability and accuracy of the movement. The guide rods 34 pass through the connecting block 33 and the support block 3 respectively, and can be connected by threaded connections, welding, or other methods.

[0027] In one embodiment of the present invention, a plurality of guide rods 34 are provided between the connecting block 33 and the support block 3. The plurality of guide rods 34 are spaced apart along the connecting block 33, and the two ends of each guide rod 34 are respectively connected to the connecting block 33 and the support block 3.

[0028] In this embodiment, combined with Figure 3 To further enhance the stability of the structure, it is understood that there are four guide rods 34 here, each guide rod 34 is set at one corner of the connecting block 33, and every two adjacent guide rods 34 are set in parallel.

[0029] In one embodiment of this utility model, a movable groove 14 is also provided on the side surface of the mounting plate 1 facing the driving member 2. The connecting rod 21 is movably limited within the movable groove 14. Therefore, the movable groove 14 is gradually reduced in size from the end near the driving member 2 to the end away from the driving member 2.

[0030] In this embodiment, combined with Figure 3 To limit the movement trajectory of the connecting rod 21, and consequently the movement trajectory of the support block 3, the moving groove 14 ensures that the connecting rod 21 can only move along a predetermined trajectory and prevents the connecting rod 21 from disengaging from the moving groove 14. The moving groove 14 can be manufactured by machining (such as milling, turning) or CNC machining to ensure its dimensional accuracy and surface quality. The gradually shrinking design prevents the connecting rod 21 from accidentally disengaging from the moving groove 14 during movement, further enhancing the reliability of the structure.

[0031] In one embodiment of the present invention, one end of the support block 3 protrudes in the direction away from the mounting plate 1 to form a contact block 35. The side of the support block 3 away from the mounting plate 1 is provided with a cover plate 32, and the cover plate 32 has a clearance groove. The contact block 35 is movably limited within the clearance groove.

[0032] In this embodiment, combined with Figure 2 and Figure 3The clearance groove is used to prevent the contact block 35 from interfering with the cover plate 32 when the cam follower 4 moves within the track groove 12 under the drive of the drive member 2, along with the support block 3. This ensures the smooth movement of the contact block 35 and avoids jamming or damage caused by interference. Figure 2 The contact block 35 includes a first segment and a second segment connected together. The first segment is inclined and connected to the support block 3. The second segment forms an angle with the first segment, which is an obtuse angle. The extension line of the second segment is parallel to the extension line of the surface of the support block 3. A through groove is provided at the end of the second segment away from the first segment, so that the second segment is generally U-shaped.

[0033] This utility model also proposes an automated device, which includes the aforementioned avoidance structure 1000. The specific structure of the avoidance structure 1000 is as described in the above embodiments. Since this second aspect adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The automated device includes, but is not limited to, CNC machine tools, automated assembly lines, electronic production equipment, etc., and is not limited here. It is understood that the avoidance structure 1000 is installed on the chassis of the automated device and cooperates with other structures.
