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.

[0030] Please see Figure 1 - Figure 7 The present invention provides a technical solution: a small billet cutting and positioning device, comprising a traveling carriage 1 and telescopic rods 2 symmetrically fixedly installed on both sides of the traveling carriage 1, wherein a side plate 4 is slidably installed on one side of the telescopic end of the telescopic rod 2.

[0031] A fixing strip 9 is slidably installed on one side of the side plate 4, and a counterweight 10 is fixedly connected to the other side of the side plate 4.

[0032] The top surface of the sleeve of the telescopic rod 2 is threaded with an upper bolt 3. The side plate 4 is provided with a side groove 5 on the side near the telescopic rod 2. The inner bottom surface of the side groove 5 is rotatably connected with a lead screw 6. The top end of the lead screw 6 passes through the side plate 4 and is fixedly connected with a top block 7.

[0033] When the telescopic rods 2 on both sides extend to the same length, the traveling carriage 1 is located at the top center of the billet body 26. When the telescopic rods 2 on both sides extend to different lengths, it is easy to adjust the position of the traveling carriage 1 to adapt to cutting at different positions.

[0034] The telescopic part of the telescopic rod 2 is fixedly connected to a slide plate 8. The slide plate 8 is threadedly connected to the lead screw 6. The slide plate 8 fits against the inner wall of the side groove 5 and is slidably connected to the side groove 5.

[0035] A rotating shaft 13 is vertically rotatably connected to the side of the fixing strip 9 away from the side plate 4. The bottom end of the rotating shaft 13 passes through the fixing strip 9 and is fixedly connected to a side roller 14. A scraping rod 15 is symmetrically fixedly connected to the outside of the rotating shaft 13.

[0036] An adjustment groove 11 is provided on the side of the side plate 4 near the fixing strip 9. The fixing strip 9 is slidably connected to the adjustment groove 11. A lower bolt 12 is threadedly connected to the bottom end of the side plate 4. The top end of the lower bolt 12 abuts against the fixing strip 9.

[0037] The scraping rod 15 has a bottom groove 16 on the side away from the rotating shaft 13. A spring 17 is fixedly connected to one side of the bottom groove 16. An adjusting rod 18 is fixedly connected to one end of the bottom groove 16. The adjusting rod 18 is slidably connected to the bottom groove 16.

[0038] There are no fewer than four scraping rods 15. A limiting groove is provided on the inner side wall of the bottom groove 16. A limiting block is fixedly connected to the outer side of the adjusting rod 18. The limiting block is slidably connected to the limiting groove.

[0039] The operator places the traveling carriage 1 at the top center of the billet body 26 to be cut, loosens the upper bolt 3, pulls the telescopic rod 2, and adjusts the position of the side plate 4 so that the side roller 14 is in contact with the outer side of the billet body 26. Then, the upper bolt 3 is tightened to fix the telescopic rod 2. Next, the top block 7 is rotated, and the positions of the telescopic rod 2 and the slide plate 8 remain unchanged. The rotation of the top block 7 adjusts the vertical height of the side plate 4. The side plate 4 drives the fixing strip 9 to move, and the fixing strip 9 drives the scraping rod 15 to move, so that the bottom surface of the scraping rod 15 is in contact with the top surface of the billet body 26. Then, the clamping bolt 19 is loosened, and the adjusting rod 18 is pulled. The adjusting rod 18 slides inside the bottom groove 16, and the adjusting rod 18 stretches the spring 17, so that the rotation of the two adjusting rods 18 can cover the top surface of the billet body 26. Then, the clamping bolt 19 is tightened to fix the adjusting rod 18.

[0040] Finally, the operator starts the traveling carriage 1, which moves the telescopic rod 2, side plate 4, and flame cutting gun 25. The flame cutting gun 25 cuts the billet body 26. The side plate 4 moves the fixing bar 9 and side roller 14. The side roller 14 contacts the lead screw 6 and rotates. The side roller 14 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the scraping rod 15 and adjusting rod 18 to rotate. Through the scraping rod 15 and adjusting rod 18, it is convenient to scrape and clean the top surface of the billet body 26 before cutting, thereby reducing the residue of impurities and reducing the situation of impurities splashing and clogging the flame cutting gun 25, thus maintaining the cutting effect.

[0041] A clamping bolt 19 is threadedly connected to the top side of the scraping rod 15, and the clamping bolt 19 abuts against the adjusting rod 18.

[0042] By loosening the lower bolt 12, the fixing strip 9 is pulled to move. The fixing strip 9 slides inside the adjustment groove 11, which facilitates the adjustment of the scraping rod 15 to the side plate 4, thereby adapting to the extension and retraction adjustment of the adjustment rod 18. This ensures that the side plate 4 does not obstruct the adjustment rod 18 when it rotates. After adjustment, tighten the lower bolt 12 to fix the fixing strip 9.

[0043] A fixed ring 20 is fixedly connected to the top center of the traveling vehicle 1. An electric push rod 22 is rotatably connected inside the fixed ring 20. A side bolt 21 is threaded inside the fixed ring 20. The side bolt 21 passes through the fixed ring 20 and abuts against the electric push rod 22.

[0044] The telescopic end of the electric push rod 22 is fixedly connected to a top plate 23, and a bending plate 24 is fixedly connected to one side bottom of the top plate 23. A flame cutting gun 25 is vertically fixedly installed inside the bending plate 24.

[0045] Working principle:

[0046] Before using this small billet cutting and positioning device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 7 As shown, the operator places the traveling carriage 1 at the top center of the billet body 26 to be cut, loosens the upper bolt 3, pulls the telescopic rod 2, and adjusts the position of the side plate 4 so that the side roller 14 is in contact with the outer side of the billet body 26. Then, the upper bolt 3 is tightened to fix the telescopic rod 2. Next, the top block 7 is rotated, and the positions of the telescopic rod 2 and the slide plate 8 remain unchanged. The rotation of the top block 7 adjusts the vertical height of the side plate 4. The side plate 4 drives the fixing strip 9 to move, and the fixing strip 9 drives the scraping rod 15 to move, so that the bottom surface of the scraping rod 15 is in contact with the top surface of the billet body 26. Then, the tightening bolt 19 is loosened, and the adjusting rod 18 is pulled. The adjusting rod 18 slides inside the bottom groove 16 and is adjusted. The rod 18 stretches the spring 17, allowing the rotation of the two adjusting rods 18 to cover the top surface of the billet body 26. Then, the clamping bolt 19 is tightened to fix the adjusting rod 18. Finally, the operator starts the traveling carriage 1, which moves the telescopic rod 2, the side plate 4, and the flame cutting gun 25. The flame cutting gun 25 cuts the billet body 26. The side plate 4 moves the fixing strip 9 and the side roller 14. The side roller 14 contacts the lead screw 6 and rotates. The side roller 14 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the scraping rod 15 and the adjusting rod 18 to rotate. Through the scraping rod 15 and the adjusting rod 18, it is convenient to pre-scrape and clean the area to be cut on the top surface of the billet body 26.
