Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an automatic walking roller frame with an anti-collision function. Background Art

[0002] In the process of continuous industrial development, with the increasing demand for large-scale workpiece processing and welding, traditional roller frames are unable to meet the requirements of efficient and precise operations. Therefore, automatic walking roller frames came into being. From the initial simple roller support structure, they gradually developed into those with power drive and automatic control functions. Today, combined with advanced sensor technology and automatic control theory, their accuracy and stability are constantly improving. The advancement of science and technology has promoted innovations in motors, materials and other fields, providing strong support for the development of automatic walking roller frames, making them an important equipment in modern industrial production.

[0003] The automatic rolling frame has performed exceptionally well in practical use. In welding, for large pipes, tanks, and other workpieces, it can automatically rotate the workpiece and move along a preset trajectory, facilitating all-round welding and ensuring uniform and beautiful welds. In machining, it can precisely control the workpiece's rotational speed and movement position, enabling it to cooperate with machine tools for cutting, grinding, and other operations, effectively improving machining accuracy. In assembly, the automatic rolling frame can easily transport and adjust the angle and position of large components, reducing labor intensity, improving assembly efficiency, and ensuring product quality. It plays a key role in numerous industrial scenarios.

[0004] In traditional automatic walking roller frames, the workpiece is placed directly on the roller bracket. Due to the gravitational potential energy when falling, the instantaneous contact with the base frame will generate a large impact force. The base frame is subjected to this impact for a long time, which is prone to metal fatigue, deformation and even breakage. This not only affects the structural stability of the roller frame, but also shortens its service life. Therefore, an automatic walking roller frame with anti-collision function is proposed to solve the above problems. Utility Model Content

[0034] The buffer assembly 11 includes a protective box 12, which is used to protect internal parts. The protective box 12 is fixedly connected to the top of the movable block 3. The protective box 12 is connected to the movable block 3. When the movable block 3 moves, the protective box 12 can be driven to move together. The top of the protective box 12 is slidably connected to a connecting plate 15. The front and rear sides of the bottom of the connecting plate 15 are fixedly connected to damping rods 16. The bottoms of the two damping rods 16 are respectively fixedly connected to the front and rear sides of the interior of the protective box 12. The connecting plate 15 is connected to the damping rod 16. The damping rod 16 is used to provide a buffer to reduce and absorb impact force. There is good pre-tightening force. The top of the connecting plate 15 is fixedly connected to the connecting rod 14, and the top of the connecting rod 14 is fixedly connected to the top plate 13. The connecting rod 14 is used to connect the top plate 13 and the connecting plate 15. The top plate 13 is used to contact the workpiece and transmit the force. The bottom of the connecting plate 15 is fixedly connected to the moving block 17. The left and right sides of the moving block 17 are slidably connected with the trapezoidal blocks 20. The moving block 17 slides with the trapezoidal blocks 20. The shape of the moving block 17 is an isosceles trapezoid, and the trapezoidal block 20 is a single-sided trapezoid. The inclined surfaces of the two trapezoidal blocks 20 are in contact with the inclined surfaces on the left and right sides of the moving block 17. The left and right sides of the movable block 17 are fixedly connected to the wedge blocks 18, and the two trapezoidal blocks 20 are provided with wedge grooves 19 on the opposite sides. The two wedge blocks 18 are slidably connected to the inside of the two wedge grooves 19 respectively. The wedge blocks 18 are used in conjunction with the wedge grooves 19. The angle of the wedge grooves 19 is the same as the angle of the inclined surface of the trapezoidal block 20. The front and rear sides of the trapezoidal block 20 are fixedly connected to the fixed blocks 21. One side of the fixed block 21 is fixedly connected to the protruding rod 22. The fixed block 21 is used to connect the protruding rod 22 and the trapezoidal block 20. When the trapezoidal block 20 moves, the fixed block 21 can be driven to move together, thereby driving the protruding rod 22 to move. The side of the protruding rod 22 away from the fixed block 21 is fixedly connected to a spring 24. The inside of the protruding rod 22 is slidably connected to a sliding rod 23. The spring 24 is sleeved on the outer periphery of the sliding rod 23. The spring 24 is used to disperse and absorb impact force and provide reaction force to make the trapezoidal block 20 move.

[0035] Reference Figure 1 - Figure 3The positioning assembly 4 includes two L-shaped blocks 7, which are fixedly connected to the left and right sides of the movable block 3 respectively. The interiors of the two L-shaped blocks 7 are rotatably connected with screws 6. The L-shaped blocks 7 are connected to the movable block 3. When the movable block 3 moves, the L-shaped blocks 7 can be driven to move together. The screws 6 are threadedly connected to the interior of the L-shaped blocks 7. When the screws 6 rotate, they can move within the L-shaped blocks 7. The two screws 6 are fixedly connected to the opposite sides with positioning plates 8. The two positioning plates 8 are slidably connected to the left and right sides of the base frame 1. One side of the screw 6 The end is connected to the positioning plate 8, and the positioning plate 8 is made of a rubber pad to increase the friction when in contact with one side of the base frame 1. The end of the screw 6 away from the positioning plate 8 is fixedly connected to the handle 5, and the handle 5 is used to facilitate the rotation of the screw 6.

The two convex blocks 9 are respectively slidably connected to the inside of the two convex grooves 10. The convex blocks 9 and the convex grooves 10 are used in conjunction with each other to ensure that the movable block 3 is limited accordingly.

[0036] Working principle: When in use, first adjust the position of the movable block 3 according to the size of the workpiece. Just move the movable block 3, and the convex block 9 slides in the convex groove 10 to change the position of the movable block 3. Then, turn the screw rod 6 by turning the handle 5. When the screw rod 6 rotates, it can drive the positioning plate 8 to rotate together. However, since the position of the L-shaped block 7 is fixed, it can move along the L-shaped block 7 when the screw rod 6 rotates until the positioning plate 8 contacts the side of the base frame 1, thereby fixing the position of the movable block 3.

[0037] When the workpiece is moved, the wedge blocks 18 on the left and right sides will slide in the wedge grooves 19 opened in the two trapezoidal blocks 20, thereby applying thrust to the two trapezoidal blocks 20 to move the trapezoidal blocks 20, and the trapezoidal blocks 20 will drive the fixed block 21 to move together when moving, and the fixed block 21 is connected to the protruding rod 22, so that the protruding rod 22 will move along the sliding rod 23 and squeeze the spring 24, and the spring 24 and the damping rod 16 are squeezed to evenly disperse the pressure of the workpiece on the top plate 13, avoiding direct contact between the workpiece and the base frame 1 and damaging the base frame 1. Then the roller bracket 2 can be controlled to move and contact the workpiece for processing.
