[0039] Example 1

[0040] like Figures 1 to 12As shown, a deburring device for angle steel towers includes a workbench 1. Two grinding devices for grinding both sides of angle steel 17 are installed on the workbench 1. The grinding devices include an L-shaped support frame 18 fixedly installed on the workbench 1. A support frame 21 is slidably installed on the L-shaped support frame 18. An adjustment device is provided between the L-shaped support frame 18 and the support frame 21. Operating the adjustment device moves the support frame 21 along the L-shaped support frame 18. Two symmetrical second mounting frames 28 are slidably installed on the support frame 21. An upper grinding roller 33 and a lower grinding roller 32 are rotatably installed on the two second mounting frames 28, respectively. Second driving components 30 for driving the upper grinding roller 33 and the lower grinding roller 32 to rotate are respectively installed on the two second mounting frames 28. A first screw 31 is fixedly installed on each of the two second mounting frames 28. A double-threaded pipe 27 is rotatably installed in the middle of the support frame 21. The two first screws 31 are threaded onto both ends of the double-threaded pipe 27. Operating the double-threaded pipe 27 adjusts the distance between the two first screws 31.

[0041] Specifically: The second mounting bracket 28 has a second mounting hole. The upper grinding roller 33 and the lower grinding roller 32 are both mounted with a coaxial second rotating shaft by bolts and nuts. The second rotating shaft is rotatably installed in the second mounting hole. The second driving component 30 is a drive motor. The output end of the drive motor is connected and fixed to the second rotating shaft. The upper grinding roller 33 is longer than the lower grinding roller 32. When the end of the lower grinding roller 32 contacts the inner surface of the other side of the angle steel 17, the upper grinding roller 33 extends out of the angle steel 17.

[0042] The L-shaped support frame 18 has a second sliding groove 19, and the support frame 21 has a second sliding block 22 fixedly installed on it. The second sliding block 22 is slidably installed in the second sliding groove 19.

[0043] The adjustment device includes a second adjusting screw 23 rotatably mounted on the second sliding block 22. A second screw hole 20 is provided on the L-shaped support frame 18. The second adjusting screw 23 is threaded into the second screw hole 20. Operating the second adjusting screw 23 drives the second sliding block 22 to move along the second sliding groove 19.

[0044] The support frame 21 has two symmetrical third sliding grooves 24, and the two ends of the second mounting bracket 28 are fixedly provided with third sliding blocks 29, which are slidably installed in the third sliding grooves 24.

[0045] Two symmetrical support plates 25 are fixedly installed in the middle of the support frame 21. A first mounting hole 26 is opened between the two support plates 25. The outer wall of the double threaded tube 27 is rotatably installed in the first mounting hole 26. The threads of the two first screws 31 are opposite and correspond to the two internal threads in the double threaded tube 27.

[0046] Specifically: A nut is fixedly installed at the middle position of the outer wall of the double-threaded tube 27, and operating the nut drives the double-threaded tube 27 to rotate.

[0047] In actual operation: the two sides of the angle steel 17 are passed through the upper grinding roller 33 and the lower grinding roller 32 of the two grinding devices respectively. The second drive component 30 is started to drive the upper grinding roller 33 and the lower grinding roller 32 to rotate through the second rotating shaft. The upper grinding roller 33 and the lower grinding roller 32 grind the outer and inner surfaces of the two sides of the angle steel 17 simultaneously. When the double threaded tube 27 is rotated along the mounting hole on the support plate 25, it drives the first screws 31 at both ends to move relative to each other or backward, thereby adjusting the distance between the two first screws 31. The first screws 31 drive the second mounting bracket 28 to move along the support frame 21, so as to adjust the distance between the upper grinding roller 33 and the lower grinding roller 32. At the same time, the second adjusting screw 23 is rotated along the second screw hole 20, which drives the second sliding block 22 to move along the second sliding groove 19 on the L-shaped support frame 18, adjusting the distance between the lower grinding roller 32 and the angle steel 17.

[0048] Example 2

[0049] Based on Example 1, such as Figure 11 and Figure 12 As shown, there is one second drive component 30, which is detachably mounted on one of the second mounting brackets 28.

The two second sprockets 3401 and the tension sprocket 3403 are connected by a second chain 3402. The output end of the second drive component 30 is connected to one of the second sprockets 3401. When the second drive component 30 is started, the upper grinding roller 33 and the lower grinding roller 32 will rotate through the transmission of the second sprocket 3401, the second chain 3402 and the tension sprocket 3403.

[0051] Specifically: the second sprocket 3401 is fixed on the second rotating shaft, the support frame 3404 has a third screw hole, the third adjusting screw 3406 is threaded into the third screw hole, the support frame 3404 has a guide hole, the second mounting base 3405 is fixedly provided with a guide rod, the guide rod is slidably installed in the guide hole, and the guide rod is parallel to the third adjusting screw 3406.

[0052] In actual operation: starting the second drive component 30 drives one of the second sprockets 3401 to rotate. Through the transmission of the tension sprocket 3403 and the second chain 3402, the other second sprocket 3401 will be driven to rotate. The two second sprockets 3401 drive the upper grinding roller 33 and the lower grinding roller 32 to rotate respectively through the second rotating shaft. When it is necessary to adjust the distance between the upper grinding roller 33 and the lower grinding roller 32, the third adjusting screw 3406 is operated to drive the second mounting base 3405 to move along the support frame 3404, thereby adjusting the position of the tension sprocket 3403. This method is suitable for deburring angle steel 17 of different sizes.

[0056] Specifically: the lower drive wheel 3 has annular grooves on both sides, corresponding to the angle steel 17, and the pressure rollers 14 on both sides of the annular groove 15 have grooves corresponding to the angle steel 17.

[0057] In actual operation: Angle steel 17 is placed between the lower drive wheel 3 and the pressure wheel 14 to limit the angle steel 17 and allow the angle steel 17 to slide between the lower drive wheel 3 and the pressure wheel 14, thereby improving the stability of the angle steel 17 during grinding. By adjusting the height of the pressure wheel 14, angle steel 17 of different sizes can be limited.

[0058] Example 4

[0059] Based on Embodiment 3, a first rotating shaft 4 is fixedly installed at one end of the lower drive wheel 3. The first rotating shaft 4 is rotatably mounted on the first mounting base 2 and extends out of the first mounting base 2. A first sprocket 5 is fixedly installed on the first rotating shaft 4. A first drive component 7 is detachably installed on the worktable 1. Two adjacent first sprockets 5 are connected by a first chain 6. The output end of the first drive component 7 is connected and fixed to one of the first sprockets 5. When the first drive component 7 is started, the lower drive wheel 3 will rotate through the transmission between the first sprocket 5 and the first chain 6, which will cooperate with the pressure roller 14 to drive the angle steel 17 to move.

[0060] Specifically: Two identical first sprockets 5 are fixedly installed on the first rotating shaft 4 of the feeding device in the middle position, and the two first sprockets 5 are respectively connected to the first sprockets 5 on the two side feeding devices through the first chain 6. The first driving component 7 is a driving component, and the first driving component 7 is installed on the worktable 1 by bolts and nuts.

[0061] In actual operation: the first drive component 7 is started to drive one of the first sprockets 5 to rotate. Through the transmission between the first sprocket 5 and the first chain 6, the first rotating shaft 4 on the three feeding devices will be driven to rotate. The first rotating shaft 4 drives the lower drive wheel 3 to rotate, which, together with the pressure roller 14, realizes the self-feeding of the angle steel 17.
