[0022] This utility model provides a fixing device for conveying bar stock, the structure of which is as follows: Figures 1-4As shown, the device includes a workbench 1. One end of the top surface of the workbench 1 has a groove 2 and a lifting mechanism. The bottom surface has a feed inlet 4 and a lifting plate 5. A U-shaped carrying plate 6 is fixed to the top of the lifting plate 5. The U-shaped carrying plate 6 has two support plates 7, and each of its two inner walls has two straight slots 8. Each of its two outer sides has a connecting plate 12, and each is fixed with a mounting block 13. Several connecting columns 9 are fixed to the bottom surface of each of the two support plates 7, and both ends of each column 9 are fixedly connected to the connecting plate 12 via sliding rods 11. A pressure plate 10 is fixed to the bottom of each connecting column 9. The sliding rods 11 are slidably connected to the straight slots 8. A first bearing 14 is fixed to the bottom of each of the two mounting blocks 13, and a first screw 15 is connected to the bottom of each of the two first bearings 14. Each first screw 15 is threadedly connected to two connecting plates 12, and its bottom end passes through the lifting plate 5 and is connected to a first pulley 16. A support block 18 is fixed to the bottom end of the lifting plate 5 via a cylinder 17. A first motor 19 is mounted on the top of the support block 18, and its output end is connected to a second pulley 20. The second pulley 20 is connected to the two first pulleys 16 via a track 21. The output end of the first motor 19 drives the second pulley 20 to rotate, causing the second pulley 20 to drive the two first pulleys 16 to rotate via the track 21. At this time, the two first screws 15 rotate and drive the two connecting plates 12 to move downwards. Finally, the two support plates 7 drive several pressure plates 10 to move downwards, pressing and fixing several bars. Using a bar conveying fixing device provides good fixing effect for batch bars and prevents slippage during conveying.

[0023] Specifically, the lifting mechanism includes a moving block 3 and a second motor 27. A first cylinder 22 is installed on the top surface of the moving block 3, and its piston rod is connected to a straight plate 23. A vertical rod 24 is fixed to the bottom surface of the other end of the straight plate 23, and a horizontal plate 25 is fixed to the bottom end of the vertical rod 24. The horizontal plate 25 and the top surfaces of the U-shaped material carrier plate 6 are both fixedly connected by columns 26. The second motor 27 is fixed to the side of the workbench 1, and its output end extends to the groove 2 and is connected to a second screw 28. A limiting block 29 that matches the groove 2 is fixed to the bottom surface of the moving block 3. The limiting block 29 is also threadedly connected to the second screw 28. The piston rod of the first cylinder 22 drives the straight plate 23, the vertical rod 24, the horizontal plate 25 and the U-shaped material carrier plate 6 to move upward through the feed port 4. Then, the output end of the second motor 27 drives the second screw 28 to rotate, so that the limiting block 29 drives the U-shaped material carrier plate 6 to move horizontally for feeding.

[0024] Furthermore, a second bearing 30 is fixed to the side wall of the groove 2. The second bearing 30 is connected to the other end of the second screw 28 to support the rotation of the second screw 28.

[0025] Furthermore, the bottom surface of the workbench 1 is provided with a material box 31, which contains several rods 32 and has fixing blocks 37 fixed on both sides of its top. The fixing blocks 37 are connected to the workbench 1 by screws 38. An L-shaped rod 34 is fixed on the side of the bottom of the material box 31. A second cylinder 35 is installed on the outer side of the other end of the L-shaped rod 34. Its piston rod passes through the L-shaped rod 34 and is connected to a push plate 36. The bottom sides of the material box 31 have discharge ports 33 through which the push plate 36 can pass. The piston rod of the second cylinder 35 drives the push plate 36 to move and push the several rods 32 into the U-shaped carrier plate 6 to fix them and feed them.

[0026] Furthermore, the bottom end of the pressure plate 10 has a V-groove 40 for better fixing effect.

[0027] Furthermore, each of the four corners at the bottom of the workbench 1 is fixed with a support column 39 for support.

[0028] The working principle of this utility model is as follows: First, the second cylinder 35 is started, and its piston rod drives the push plate 36 to move and push several bars 32 into the U-shaped carrier plate 6. Then, the output end of the first motor 19 is started to drive the second pulley 20 to rotate, so that the second pulley 20 drives the two first pulleys 16 to rotate through the track 21. At this time, the two first screws 15 rotate and drive the two connecting plates 12 to move downward. The two support plates 7 drive several pressure plates 10 to move downward to press and fix several bars. Next, the first cylinder 22 is started, and its piston rod drives the straight plate 23, vertical rod 24, horizontal plate 25 and U-shaped carrier plate 6 to move upward and pass through the feed port 4. Finally, the second motor 27 is started, and its output end drives the second screw 28 to rotate, so that the limiting block 29 drives the U-shaped carrier plate 6 to move horizontally to feed materials.
