Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding mechanism for processing metal guardrails. Background Art

[0002] Metal guardrails refer to a general term for guardrails made of metal materials, including wrought iron guardrails, zinc steel guardrails, stainless steel guardrails, cast iron guardrails, aluminum alloy guardrails and other types. These guardrails not only have the characteristics of high strength, corrosion resistance, fatigue resistance, and not easy to deform, but also have simple structures, easy to manufacture and install, and can flexibly adapt to different environmental requirements. Therefore, metal guardrails are widely used in roads, railways, bridges, airports, stadiums and other places.

[0003] When grinding existing metal guardrails, workers usually need to hold the metal rod to operate, which is laborious and has certain safety hazards. Therefore, the existing patent with publication number CN217832951U proposes a grinding mechanism for metal guardrail processing. It places one end of the metal rod into the clamping frame for clamping, and the other end is placed on the top of the rotating seat through the setting of the movable frame, the mounting sleeve and the clamping frame. The motor is turned on to drive the clamping frame and the metal rod to rotate, the driving device is turned on to drive the grinding roller to grind the metal rod, and the mounting sleeve is pushed to move through the movable frame to grind different positions of the metal rod. Then, the position of the metal rod is adjusted and re-clamped to grind the other end again. The structure is reasonable, easy to operate, and the quality of grinding is improved. At the same time, it is easy to push, saving time and effort, and improving the efficiency of the grinding operation.

[0004] However, in the above technical solution, although the metal rod can be clamped by the clamping frame, its clamping plate is flat, and the contact area of ​​the flat clamping on the metal rod is relatively limited, which may cause the metal rod to separate from the clamping frame when the motor rotates, causing damage to the metal rod. Therefore, the utility model aims to provide a more stable grinding mechanism that can clamp the metal rod when grinding the metal rod. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a grinding mechanism for metal guardrail processing, which can clamp the metal rod more stably when grinding the metal rod, so as to solve the problem that the clamping frame in the existing technology is difficult to clamp the metal rod stably when the metal rod is being ground.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a grinding mechanism for metal guardrail processing, comprising a supporting platform and a grinding platform arranged on the supporting platform, a metal rod being placed on the grinding platform, and also comprising a movable seat, which is arranged on the supporting platform, and a motor is provided on the movable seat, and the output end of the motor is relatively fixed to a fixed plate; two clamping plates, which are relatively spaced apart and respectively arranged at the two ends of the fixed plate, and flexible arc-shaped clamping parts are respectively provided on the two clamping plates, and a reset mechanism is also provided between the two clamping plates to drive the two clamping plates to be relatively close; and a locking mechanism, which can selectively fix the two clamping plates relative to each other to limit or allow the two clamping plates to move relative to each other.

[0007] Optionally, the reset mechanism includes a guide rod, two limiting parts and two springs. A T-shaped slot is provided on the fixed plate along its length direction. The clamping plate protrudes toward one end of the fixed plate to form a T-shaped sliding block. The sliding block is arranged in the T-shaped slot. The guide rod movably passes through the two clamping plates. The two limiting parts are respectively arranged at opposite ends of the guide rod. The two springs are respectively mounted on the guide rod and elastically abut against the clamping plates respectively.

[0008] Optionally, the locking mechanism includes a screw and a nut, the screw movably passes through the two clamping plates and is threadedly connected to the two clamping plates, and the nut is threadedly connected to the screw.

[0009] Optionally, a movable groove is provided on the supporting platform along its length direction, a screw rod is rotatably provided in the movable groove, a movable block is protruded from the bottom of the movable seat, and the movable block is threadedly connected to the screw rod.

[0010] Optionally, one end of the screw rod movably passes through the supporting platform, and the free end of the screw rod is provided with an L-shaped handle.

[0011] Optionally, a friction-enhancing sleeve is provided on the free end of the handle.

[0012] Compared with the prior art, the present invention provides a grinding mechanism for metal guardrail processing, which has the following beneficial effects:

[0013] The utility model provides an arc-shaped clamping portion. When the two clamping plates are driven by the reset mechanism to approach each other, the arc-shaped clamping portions on the two clamping plates clamp the metal rod. The arc surface of the arc-shaped clamping portion increases the contact area between the arc-shaped clamping portion and the metal rod. Finally, the locking mechanism is used to relatively fix the two clamping plates, thereby improving the stability of the clamping plates clamping the metal rod.

[0014] The utility model provides a turning handle, and when the user needs to turn the screw rod, the user can turn the screw rod by turning the handle. The turning handle provides the user with a fulcrum for turning the screw rod, making it easier for the user to turn the screw rod.

[0015] The utility model provides a friction-enhancing sleeve. When a user rotates the handgrip, the friction-enhancing sleeve sleeved on the free end of the handgrip increases the friction between the user's palm and the handgrip, thereby increasing the user's stability when rotating the handgrip.

[0024] When the user uses the clamping plates 7 to clamp the metal rod 3, he first pulls the two clamping plates 7 apart so that the distance between the two clamping plates 7 can accommodate the metal rod 3, and then places the metal rod 3 between the two clamping plates 7. At this time, the clamping plates 7 are released, so that the two clamping plates 7 are driven by the reset mechanism 9 to approach each other, so that the arc-shaped clamping parts 8 on the two clamping plates 7 clamp the metal rod 3. The arc surface of the arc-shaped clamping part 8 will increase the contact area between it and the metal rod 3. Finally, the locking mechanism 10 is used to fix the two clamping plates 7 relative to each other, thereby improving the stability of the clamping plates 7 in clamping the metal rod 3.

[0025] In this embodiment, the reset mechanism 9 includes a guide rod 11, two limiting parts 12 and two springs 13. A T-shaped slot 14 is provided on the fixed plate 6 along its length direction. The clamping plate 7 protrudes toward one end of the fixed plate 6 to form a T-shaped sliding block 15. The sliding block 15 is arranged in the T-shaped slot 14. The guide rod 11 movably passes through the two clamping plates 7. The two limiting parts 12 are respectively arranged at the opposite ends of the guide rod 11. The two springs 13 are respectively mounted on the guide rod 11 and elastically abut the clamping plates 7 respectively; when the user pulls apart the two clamping plates 7 and releases his hand, the two clamping plates 7 will be elastically abutted by the springs 13 located at both ends of the guide rod 11 to bring the two clamping plates 7 relatively close.

[0026] In this embodiment, the locking mechanism 10 includes a screw 16 and a nut 17. The screw 16 movably passes through the two clamping plates 7 and is threadedly connected to the two clamping plates 7. The nut 17 is threadedly connected to the screw 16. When the user needs to fix the two clamping plates 7 relative to each other, the screw 16 is threaded through the two clamping plates 7, and then the nut 17 is threadedly connected to the screw 16 to fix the two clamping plates 7 relative to each other.

[0027] In this embodiment, a movable groove 18 is provided on the supporting platform 1 along its length direction, and a wire rod 19 is rotatably provided in the movable groove 18. A movable block 22 is formed on the bottom of the movable seat 4, and the movable block 22 is threadedly connected to the wire rod 19; when one end of the metal rod 3 is polished on the polishing table 2, the movable block 22 is driven to move by rotating the wire rod 19, and the movement of the movable block 22 will drive the movable seat 4 to move, so as to drive the motor 5 to approach or move away from the polishing table 2, thereby controlling the movement of the metal rod 3 along its length, making it convenient for the user to polish various parts of the metal rod 3.

[0028] In this embodiment, one end of the screw rod 19 is movable through the supporting platform 1, and the free end of the screw rod 19 is provided with an L-shaped handle 20; when the user needs to rotate the screw rod 19, the handle 20 is used to rotate the screw rod 19, and the handle 20 will provide the user with a fulcrum for rotating the screw rod 19, making it easier for the user to rotate the screw rod 19.

[0029] In this embodiment, a friction-enhancing sleeve 21 is provided on the free end of the rotating handle 20; when the user rotates the rotating handle 20, the friction-enhancing sleeve 21 provided on the free end of the rotating handle 20 increases the friction between the user's palm and the rotating handle 20, thereby increasing the user's stability when rotating the rotating handle 20.

[0030] Working principle: When the user uses the clamping plates 7 to clamp the metal rod 3, the user first pulls the two clamping plates 7 apart so that the distance between the two clamping plates 7 can accommodate the metal rod 3, and then places the metal rod 3 between the two clamping plates 7. At this time, the clamping plates 7 are loosened, and the two clamping plates 7 are elastically abutted by the springs 13 located at both ends of the guide rod 11, so as to bring the two clamping plates 7 closer together, so that the arc-shaped clamping parts 8 on the two clamping plates 7 clamp the metal rod 3. The arc surface of the arc-shaped clamping part 8 increases the contact area between it and the metal rod 3. Finally, the screw 16 is threaded through the two clamping plates 7, and then the nut 17 is used to thread the screw 16 to fix the two clamping plates 7 relatively, thereby improving the clamping plate 7 to the metal rod 3. Stability of clamping; when one end of the metal rod 3 is polished on the polishing table 2, the moving block 22 is driven to move by rotating the screw rod 19, and the movement of the moving block 22 will drive the moving seat 4 to move, so as to drive the motor 5 to move closer to or away from the polishing table 2, thereby controlling the metal rod 3 to move along its length, which is convenient for the user to polish various parts of the metal rod 3. When the user needs to rotate the screw rod 19, the user rotates the screw rod 19 by turning the hand 20. The hand 20 will give the user a fulcrum for rotating the screw rod 19, which is convenient for the user to rotate the screw rod 19. When the user rotates the hand 20, the friction-increasing sleeve 21 mounted on the free end of the hand 20 will increase the friction between the user's palm and the hand 20, so as to increase the stability of the user when rotating the hand 20.
