Description

Technical Field

[0001] This utility model relates to the field of protective buffer structure technology, specifically to a collision-resistant electromechanical end protective buffer structure. Background Technology

[0002] On automated production lines, various electromechanical equipment such as robotic arms and conveying devices move frequently. When they reach the end of their travel, a collision may occur, potentially causing equipment damage, production stoppage, or even endangering the safety of operators. Protective buffer structures can provide buffering force when the equipment is about to reach the end, reducing the impact of collisions, protecting critical components of the equipment, and ensuring the continuous and stable operation of the production line.

[0003] The existing technology has the following problems: The existing device cannot provide dual shock absorption for the protective plate during use. The lack of dual shock absorption means that when the protective plate is subjected to a collision impact, it can only rely on a single shock absorption mechanism to buffer the energy. This makes the protective plate bear a large instantaneous impact force, which can easily lead to deformation, cracking and other damage to the protective plate. In addition, the existing device cannot replace the protective plate. When the protective plate is worn, deformed or damaged due to a collision, if the protective plate cannot be replaced, maintenance personnel need to disassemble and repair the entire buffer structure. This not only requires removing the components connected to the protective plate, but may also involve disassembling complex components inside the buffer structure, which greatly increases the workload and difficulty of maintenance.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes the utility model in conjunction with specific embodiments.

[0015] like Figure 1 As shown, this utility model provides a collision-resistant electromechanical end protection buffer structure, including a fixed frame 1. Mounting plates 2 are fixedly connected to both the left and right sides of the fixed frame 1. Two fixed posts 3 are fixedly connected to the inner surface of the fixed frame 1. A lifting plate 5 is slidably connected to the outer wall of the fixed posts 3. Two first springs 4 are sleeved on the outer wall of the fixed posts 3. One end of the first spring 4 is fixedly connected to the lifting plate 5, and the other end of the first spring 4 is fixedly connected to the fixed frame 1. Connecting posts 6 are fixedly connected to both the upper and lower sides of the lifting plate 5. A snap-fit ​​mechanism 7 is provided inside the connecting post 6. A protective plate 8 is fixedly connected to the end of the connecting post 6 away from the lifting plate 5. This collision-resistant electromechanical end protection... The buffer structure uses a fixed frame 1 as the main frame, and mounting plates 2 on its left and right sides are used to install the entire structure onto the corresponding electromechanical equipment. Two fixed columns 3 fixed on the inner surface of the fixed frame 1 provide sliding tracks for the lifting plate 5. The first spring 4 sleeved on the outer wall of the fixed column 3 connects the lifting plate 5 and the fixed frame 1 at both ends. When the protective plate 8 is subjected to a collision impact force, the force is transmitted to the lifting plate 5 through the connecting column 6. The lifting plate 5 will slide along the fixed column 3 and compress the first spring 4. The first spring 4 undergoes elastic deformation, converting part of the collision kinetic energy into elastic potential energy, thereby achieving initial shock absorption of the protective plate 8 and playing a buffering role, reducing the instantaneous impact force on the protective plate 8.

[0016] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, two rotating plates 10 are rotatably connected to the upper and lower sides of the inner surface of the fixed frame 1. A moving block 9 is rotatably connected to the other end of the rotating plate 10. A damper 13 is fixedly connected to the opposite face of the two moving blocks 9. A second spring 14 is sleeved on the outer wall of the damper 13. Both ends of the second spring 14 are fixedly connected to the moving block 9. A limit block 11 is fixedly connected to the side of the moving block 9 near the lifting plate 5. Two limit grooves 12 are opened on the upper and lower sides of the lifting plate 5. The outer wall of the limit block 11 is slidably connected to the limit groove 12. The other end of the rotating plate 10 rotatably connected to the upper and lower sides of the inner surface of the fixed frame 1 is rotatably connected to the moving block 9. The two movable blocks 9 are connected face to face with a damper 13, and a second spring 14 is sleeved on the outside. The limiting block 11 of the movable block 9 near the lifting plate 5 slides in cooperation with the limiting groove 12 opened on the lifting plate 5. When the lifting plate 5 moves due to the impact force, the movable block 9 will move through the rotating plate 10. While compressing the second spring 14, the piston inside the damper 13 moves in the hydraulic oil and generates a damping force. The elastic buffer of the second spring 14 and the damping effect of the damper 13 together constitute the second shock absorption, further absorbing the remaining energy of the collision, realizing the double shock absorption of the protective plate 8, effectively preventing the protective plate 8 from being severely deformed or broken due to excessive impact force, and extending its service life.

[0017] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, the protective plate 8 has an opening 15 on the side near the lifting plate 5, the outer wall of the connecting column 6 is movably connected to the opening 15, and slots 16 are provided on both the left and right sides of the inner surface of the opening 15. The locking mechanism 7 includes a knob 71, a worm gear 72 is fixedly connected to the rear side of the knob 71, a worm wheel 73 is meshed with the outer wall of the worm gear 72, a rotating rod 74 is fixedly connected through the upper side of the outer wall of the worm wheel 73, and the outer wall of the worm gear 72 is rotatably connected to the connecting column 6. A first bevel gear 75 is fixedly connected to the upper end of the rotating rod 74. A second bevel gear 76 is meshed with the outer wall of the first bevel gear 75. A threaded rod 77 is fixedly connected through the left side of the second bevel gear 76. Two inserts 79 are threadedly connected to the outer wall of the threaded rod 77. The threads at the left and right ends of the outer wall of the threaded rod 77 are in opposite directions. The outer walls of the inserts 79 are slidably connected to the connecting post 6 and are engaged with the slot 16. Two limiting posts 78 are fixedly connected to the inner surface of the connecting post 6. The outer wall is slidably connected to the insert block 79. The opening 15 on the side of the protective plate 8 near the lifting plate 5 is used for the insertion of the connecting column 6. The slots 16 on both sides of the inner surface of the opening 15 cooperate with the snap-fit ​​mechanism 7 to fix the protective plate 8. In the snap-fit ​​mechanism 7, the worm 72 connected to the rear side of the knob 71 meshes with the worm wheel 73. When the knob 71 is rotated, the worm 72 drives the worm wheel 73 to rotate. The worm wheel 73 causes the first bevel gear 75 to rotate through the rotating rod 74. The first bevel gear 75 then drives the second bevel gear 76 that meshes with it to rotate. The second bevel gear 76 then drives the threaded rod 77 to rotate. Since the threads at both ends of the threaded rod 77 are in opposite directions, the two inserts 79 connected by the thread will slide towards or away from each other along the limiting post 78 on the inner surface of the connecting post 6 when the threaded rod 77 rotates. When it is necessary to replace the protective plate 8, turn the knob 71 to disengage the inserts 79 from the slot 16, and the protective plate 8 can be removed from the connecting post 6, realizing the quick replacement of the protective plate 8, which is convenient for maintenance personnel to replace the damaged protective plate 8 and shorten the maintenance time.

[0018] The working principle of this anti-collision electromechanical end protection buffer structure will be explained in detail below.

[0019] like Figure 1-5As shown, a rotating plate 10 is rotatably connected to the upper and lower sides of the inner surface of the fixed frame 1, and its other end is rotatably connected to a moving block 9. A damper 13 is connected to the opposite faces of the two moving blocks 9, and a second spring 14 is externally sleeved on the damper. A limiting block 11 on the side of the moving block 9 near the lifting plate 5 slides in cooperation with a limiting groove 12 on the lifting plate 5. When the lifting plate 5 moves due to impact, the rotating plate 10 causes the moving block 9 to move, compressing the second spring 14. Simultaneously, the piston inside the damper 13 moves in the hydraulic oil, generating damping force. The elastic buffering of the second spring 14 and the damping effect of the damper 13 together constitute a second shock absorption, further absorbing the remaining energy of the impact and achieving double shock absorption for the protective plate 8. This effectively prevents the protective plate 8 from being severely deformed or broken due to excessive impact force, extending its service life. The opening 15 on the side of the protective plate 8 near the lifting plate 5 is used for inserting the connecting column 6. The slots 16 on both sides of the inner surface of the opening 15 cooperate with the snap-fit ​​mechanism 7 to fix the protective plate 8. In the snap-fit ​​mechanism 7, the worm 72 connected to the rear side of the knob 71 meshes with the worm wheel 73. When the knob 71 is turned, the worm 72 drives the worm wheel 73 to rotate. The worm wheel 73 causes the first bevel gear 75 to rotate through the rotating rod 74. The first bevel gear 75 then drives the second bevel gear 76 that meshes with it to rotate. The second bevel gear 76 then drives the threaded rod 77 to rotate. Since the threads at both ends of the threaded rod 77 are opposite in direction, the two threaded blocks 79 will slide towards or away from each other along the limiting post 78 on the inner surface of the connecting post 6 when the threaded rod 77 rotates. When the protective plate 8 needs to be replaced, the knob 71 is turned to disengage the blocks 79 from the slots 16, and the protective plate 8 can be removed from the connecting post 6, realizing the quick replacement of the protective plate 8, which is convenient for maintenance personnel to replace the damaged protective plate 8 and shorten the maintenance time.
