Description

Technical Field

[0001] The present invention relates to the field of positioning technology, and in particular to a positioning device for thermal cutting of guardrail plates and a method of using the positioning device. Background Art

[0002] The guardrail is a composite plate movable steel guardrail used at the opening of the central dividing strip of the highway. The guardrail consists of two steel guardrail plates and two columns fixedly clamped between them. The two columns are clamped between the two steel guardrail plates by installing ears and bolts. During the production process of the guardrail plates, it is necessary to cut holes at both ends to facilitate the subsequent connection with the columns. The cutting process of the guardrail plates is processed by a laser cutting machine. During the processing, the guardrail plates need to be clamped and positioned to avoid the guardrail plates from shifting during the processing, which may cause the laser cutting machine to be inaccurately positioned.

[0003] At present, before the guardrail plate is moved to the nail plate for hot cutting, it is necessary to add a positioning device on the nail plate to fix and cut the guardrail plate. After the cutting is completed, the clamping device needs to be removed, which increases the cumbersomeness of the operation and is not conducive to improving production efficiency. At the same time, as the nail plate is used, slag is bound to hang on the nail plate. As the iron slag accumulates, the nail plate is no longer flat. For this reason, we propose a positioning device for thermal cutting of guardrail plates and a method for using the same. Summary of the invention

[0054] A method for using a positioning device for thermal cutting of guardrail plates, the process is as follows:

[0055] S1: transporting the guardrail plate to be cut to the thorn strip 3 via the conveyor belt 9;

[0056] S2: transporting the guardrail plate to the designated position of the mounting frame 4 through the driving mechanism 2 and the barbed strip 3, and stopping the transportation of the guardrail plate;

[0057] S3: The clamping mechanism 6 is turned over 90 degrees through the linkage mechanism 5. During the turning process of the clamping mechanism 6, the vibration mechanism 7 descends, and the striking hammer 72 in the vibration mechanism 7 is embedded between the thorn strips 3;

[0058] S4: The clamping plate 64 in the clamping mechanism 6 is extended through the pushing mechanism 8, and the guardrail plate is clamped by the clamping plates 64 on both sides of the guardrail plate. In the process of extending the clamping plate 64, the striking hammer 72 strikes the barbed bar 3 to clean the iron filings on the barbed bar 3.

[0059] The working process of the present invention is as follows:

[0060] When in use, the guardrail plate is transported to the conveying barbed plate composed of barbed strips 3 on the mounting frame 4 by the conveyor belt 9. When the guardrail plate is transported to the designated position on the mounting frame 4, the slider 1 53 on the bidirectional screw rod 521 is moved inward by starting the driving motor 2 52. When the slider 1 53 moves, the rack 1 531 on the slider 1 53 causes the gear 1 532 to rotate, thereby causing the mounting strip 62 to deflect 90 degrees. When the slider 1 53 moves, the connecting seat 71 is moved downward along the limiting plate 511 by the connecting rod 54 until it stops, and the striking hammer 72 is embedded between the barbed strips 3.

[0061] Then, the cylinder 81 is started to extend the push bar 82, and the push bar 82 is squeezed with the moving block 63, so that the moving block 63 rises, and the slider 2 653 is lifted by the push rod 631, and then the clamping plate 64 is extended through the deflection rod 1 651 and the deflection rod 2 652, so that the relative clamping plate 64 clamps and fixes the guardrail plate. In the process of moving the push bar 82, the push bar 82 rotates the gear 3 831 through the rack 2 83, and then the gear 2 732 rotates, and multiple The vertical rod 731 rotates synchronously through the toothed belt 74. When the vertical rod 731 rotates, the cam 733 on the vertical rod 731 squeezes the upper end of the striking hammer 72, so that the striking hammer 72 strikes the barb 3. When the cam 733 separates from the striking hammer 72, the striking hammer 72 is reset by the spring 2 722. As the cam 733 continuously squeezes the striking hammer 72, the striking hammer 72 continuously strikes the barb 3 when the gear 3 831 rotates, thereby cleaning the iron filings adhering to the barb 3.
