[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of a burr-removing device for guardrail production, comprising an I-beam clamp 1 (existing technology, not described in detail) for installation on different work platforms. A threaded rod 2 is threadedly connected to the bottom of the outer wall of the I-beam clamp 1, which is manually rotated to clamp work platforms of different thicknesses. A support plate 3 is fixedly connected to the top of the outer wall of the I-beam clamp 1, providing support and a rotation origin for the grinding frame 4. The rotation angle of the grinding frame 4 is changed by a limiting component. The inner wall of the support plate 3 is connected to the grinding frame 4 via a limiting component. The grinding frame 4 simultaneously drives two sets of grinding blocks 6 to rotate. A motor 5 is fixedly connected to the inner wall of the grinding frame 4 (existing technology, not described in detail), driving the grinding blocks 6 to grind the guardrail cross-section. The output end of the motor 5 is connected to the grinding blocks 6 via a quick-release component. Two sets of grinding blocks 6 are provided, with symmetrical inclined surfaces for grinding guardrail cross-sections of different lengths and widths. The back of the outer wall of the grinding frame 4 is slidably connected to the outer wall of the support plate 3.
[0033] Reference Figures 2-4 The quick-release assembly includes a fixed frame 7, which provides a locking space for the fixed rod 8 to keep the fixed rod 8 stable. The bottom of the outer wall of the fixed frame 7 is fixedly connected to the output shaft of the motor 5. The inner wall of the fixed frame 7 is slidably connected to the fixed rod 8, which is used to extend the grinding block 6 to lock onto the fixed frame 7. The outer wall of the fixed rod 8 is fixedly connected to a guide block 9, which is used to lock onto the inner wall of the fixed frame 7, so that the fixed frame 7 can drive the fixed rod 8 to rotate while sliding on the inner wall of the fixed frame 7. The top of the outer wall of the fixed rod 8 has a fixing hole 10, which is used to lock onto a bolt 11 to fix the fixed rod 8 to the inner wall of the fixed frame 7. The top of the outer wall of the fixed frame 7 is threaded with a bolt 11, which is provided with a short-pitch thread for quick rotation to loosen the fixed rod 8. The outer wall of the guide block 9 is slidably connected to the inner wall of the fixed frame 7. The top of the outer wall of the fixed rod 8 is fixedly connected to the back of the outer wall of the grinding block 6. The bottom of the outer wall of the bolt 11 is locked onto the inner wall of the fixing hole 10.
[0034] Reference Figures 3-5The limiting assembly includes a rotating shaft 12, which provides the rotation origin for the grinding frame 4 and drives it to rotate via a limiting frame 15. The bottom end of the outer wall of the rotating shaft 12 is fixedly connected to the outer wall of the grinding frame 4. A directional block 13 is fixedly connected to the outer wall of the rotating shaft 12, which engages with a directional groove 16 to maintain the stable movement of the limiting frame 15. The top end of the outer wall of the rotating shaft 12 is elastically connected to the limiting frame 15 via a limiting spring 14. The limiting frame 15 is for manual release from the external limiting position and is equipped with a handle for easy manual rotation. A directional groove 16 is formed on the inner wall of the limiting frame 15, which engages with the directional block 13, allowing the limiting frame 15 to slide on the outer wall of the rotating shaft 12 and also drive the rotating shaft 12 to rotate. A limiting block 17 is fixedly connected to the bottom end of the outer wall of the limiting frame 15, which engages with the limiting groove 16. 8. The rotation angle of the fixed rotating shaft 12 is fixed. The top of the outer wall of the support plate 3 is provided with a limiting groove 18. Several sets of limiting grooves 18 are provided for multiple locking limiting blocks 17 to fix the rotation angle of two sets of grinding blocks 6. One end of the limiting spring 14 is fixedly connected to the top of the outer wall of the rotating shaft 12, and the other end of the limiting spring 14 is fixedly connected to the top of the inner wall of the limiting frame 15. Through the object extrusion force between the limiting spring 14 and the rotating shaft 12, the limiting block 17 is always locked on the inner wall of the limiting groove 18 without being affected by external force. The outer wall of the rotating shaft 12 is slidably connected to the top inner wall of the support plate 3. The outer wall of the directional block 13 is slidably connected to the inner wall of the directional groove 16. The inner wall of the limiting frame 15 is slidably connected to the outer wall of the rotating shaft 12. The end of the outer wall of the limiting block 17 is locked on the inner wall of the limiting groove 18.
[0035] Working principle: When grinding guardrail sections of different shapes, the limiting frame 15 is manually pulled to disengage the limiting block 17 from the limiting groove 18 to release the limiting. Then, the limiting frame 15 is rotated to drive the rotating shaft 12 to rotate, which in turn drives the grinding frame 4 to rotate. The grinding frame 4 then drives the motor 5 to rotate, which in turn drives the grinding block 6 to rotate to the required angle. Then, the limiting frame 15 is pushed inward to engage the limiting block 17 into the corresponding limiting groove 18. Finally, the guardrail section is placed against the surface of the grinding block 6, and the motor 5 is turned on to drive the grinding block 6 to perform the grinding operation. This allows for the grinding of guardrail sections of different shapes, reducing errors from manual grinding and improving production quality.
[0036] When disassembling and replacing the grinding block 6, manually rotate the bolt 11 to disengage from the fixing hole 10 to release the limit. Then, manually remove the grinding block 6 and the fixing rod 8 along the fixing frame 7. Align the fixing rod 8 and the guide block 9 on the back of the new grinding block 6 with the fixing frame 7 and insert them so that the fixing hole 10 is quickly aligned with the bottom of the bolt 11. Then, rotate the bolt 11 to lower it and engage it with the inner wall of the fixing hole 10. This allows for quick disassembly and installation of the grinding block 6 and improves grinding efficiency.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
