[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0023] Please see Figure 1-6The present invention provides the following technical solution: a U-shaped iron groove turning device, including a base 1, a support leg 3 fixedly connected to the lower corner of the base 1, a support rod 7 fixedly connected to the upper side of the base 1, a top plate 6 fixedly connected to the upper end of the support rod 7, four sets of positioning grooves 2 opened at the center of the upper end of the base 1, the U-shaped iron body 4 is placed inside the positioning groove 2, a U-shaped iron positioning and fixing mechanism 8 is provided at the upper end of the base 1 near the positioning groove 2, and an automatic U-shaped iron processing mechanism 5 is provided at the upper end of the top plate 6.

[0024] Specifically, the U-shaped iron automatic processing mechanism 5 includes a hydraulic cylinder 51, a grinding wheel 54, a drive shaft 55, a motor 56, an automatic processing control system 57, and a mounting plate 58. The hydraulic cylinder 51 is mounted on the upper end of the top plate 6. The output end of the hydraulic cylinder 51 is equipped with the mounting plate 58. Four motors 56 are mounted on the lower end of the mounting plate 58, directly above the four positioning slots 2. The output end of each motor 56 is equipped with a drive shaft 55. The lower end of the drive shaft 55 is fixedly connected to the grinding wheel 54. The automatic processing control system 57 is located on the upper end of the mounting plate 58, near the hydraulic cylinder 51.

[0025] By adopting the above technical solution, when processing the U-shaped iron, the hydraulic cylinder 51 is opened, the hydraulic cylinder 51 drives the mounting plate 58 to descend, the mounting plate 58 descends and drives the grinding wheel 54 to insert into the groove inside the U-shaped iron body 4, and then the motor 56 is opened, the motor 56 drives the drive shaft 55 to rotate through the output end, and the drive shaft 55 rotates and drives the grinding wheel 54 to process the U-shaped iron body 4.

[0026] Specifically, the U-shaped iron automatic processing mechanism 5 also includes a buffer spring 52 and a telescopic rod 53. The telescopic rod 53 is installed on the upper side of the mounting plate 58. The upper end of the telescopic rod 53 is fixed to the lower end face of the top plate 6. The buffer spring 52 is sleeved on the surface of the telescopic rod 53. The upper and lower ends of the buffer spring 52 are welded to the lower surface of the top plate 6 and the upper end face of the mounting plate 58.

[0027] By adopting the above technical solution, when the mounting plate 58 descends, it will cause the telescopic rod 53 to extend. The extension of the telescopic rod 53 will cause the buffer spring 52 to extend, thereby buffering the descent process of the mounting plate 58 and improving the stability of the descent process of the mounting plate 58.

[0028] Specifically, the automatic processing control system 57 includes a PLC controller 571, an infrared receiver 572, and an infrared transmitter 573. The infrared receiver 572 is installed on the upper end of the mounting plate 58 near the hydraulic cylinder 51, and the infrared transmitter 573 is installed on the lower end of the top plate 6 corresponding to the position of the infrared receiver 572. The PLC controller 571 is installed at the upper corner of the base 1. The PLC controller 571, the infrared receiver 572, and the infrared transmitter 573 are all electrically connected by wires.

[0029] By adopting the above technical solution, when the mounting plate 58 descends, the infrared rays emitted by the infrared transmitter 573 will be received by the infrared receiver 572. When the mounting plate 58 descends to the groove inside the U-shaped iron body 4 where the grinding wheel 54 is inserted, the PLC controller 571 receives the signal and controls the hydraulic cylinder 51 to shut down and the motor 56 to start, thereby automatically processing the U-shaped iron body 4.

[0030] In this embodiment, when processing the U-shaped iron, the hydraulic cylinder 51 is opened, causing the mounting plate 58 to descend. The descent of the mounting plate 58 causes the grinding wheel 54 to insert into the groove inside the U-shaped iron body 4. Then, the motor 56 is turned on, and the motor 56 drives the drive shaft 55 to rotate through its output end. The rotation of the drive shaft 55 drives the grinding wheel 54 to process the U-shaped iron body 4. When the mounting plate 58 descends, it causes the telescopic rod 53 to extend. The extension of the telescopic rod 53 causes the buffer spring 52 to extend, thereby buffering the descent of the mounting plate 58 and improving the stability of the descent process. When the mounting plate 58 descends, the infrared rays emitted by the infrared transmitter 573 are received by the infrared receiver 572. When the mounting plate 58 descends to the point where the grinding wheel 54 is inserted into the groove inside the U-shaped iron body 4, the PLC controller 571 receives the signal and controls the hydraulic cylinder 51 to shut down and the motor 56 to start, thereby automatically processing the U-shaped iron body 4. Example

[0031] The difference between this embodiment and Embodiment 1 is that the U-shaped iron positioning and fixing mechanism 8 includes a fixing component 81, a T-shaped slide groove 82, a positioning plate 83, screws 84, a slot 85, and a T-shaped slider 86. A T-shaped slide groove 82 is provided at the upper end of the base 1 near the positioning groove 2. A T-shaped slider 86 is slidably connected inside the T-shaped slide groove 82. The positioning plate 83 is fixed to the upper end of the T-shaped slider 86. The T-shaped slider 86 and the positioning plate 83 are fixedly connected by screws 84. A slot 85 is provided on the side of the T-shaped slider 86, and a fixing component 81 is provided inside the side of the T-shaped slide groove 82.

[0032] By adopting the above technical solution, when processing the U-shaped iron body 4, the U-shaped iron body 4 is first placed entirely into the positioning groove 2. Then, by sliding the positioning plate 83, the positioning plate 83 drives the T-shaped slider 86 inside the T-shaped groove 82 until the T-shaped slider 86 slides to the other end of the T-shaped groove 82. At this time, the positioning plate 83 can fix the upper edge of the U-shaped iron body 4, thus facilitating the processing of the U-shaped iron body 4.

[0033] Specifically, the fixing component 81 includes an adjusting groove 811, an adjusting block 812, a locking block 813, a limiting plate 814, and a compression spring 815. A compression spring 815 is installed inside the side of the T-shaped slide groove 82. A limiting plate 814 is installed at the other end of the compression spring 815, and a locking block 813 is installed at the other end of the limiting plate 814. One side of the locking block 813 has an arc-shaped structure. An adjusting block 812 is installed at the upper end of the limiting plate 814. An adjusting groove 811 corresponding to the adjusting block 812 is opened at the upper end of the base 1.

[0034] By adopting the above technical solution, when the T-shaped slider 86 slides in the T-shaped groove 82, since one side of the locking block 813 is set with an arc structure, the T-shaped slider 86 will squeeze the locking block 813. After the locking block 813 is squeezed, it will compress the limiting plate 814 and the compression spring 815, and make the locking block 813 embedded in the interior of the base 1. When the locking block 813 is aligned with the slot 85, the compression spring 815 will rebound, thereby driving the locking block 813 to insert into the interior of the slot 85, so as to fix the T-shaped slider 86. When it is necessary to control the T-shaped slider 86 to reset, the adjusting block 812 in the sliding adjusting groove 811 will slide. The adjusting block 812 will drive the limiting plate 814 to slide and compress the compression spring 815, while controlling the locking block 813 to slide out from the interior of the slot 85, thereby controlling the T-shaped slider 86 to reset.

[0035] In this embodiment, when processing the U-shaped iron body 4, the entire U-shaped iron body 4 is first placed into the positioning groove 2. Then, the positioning plate 83 is slidable, which drives the T-shaped slider 86 inside the T-shaped groove 82 until the T-shaped slider 86 slides to the other end of the T-shaped groove 82. At this point, the positioning plate 83 can fix the upper edge of the U-shaped iron body 4, thus facilitating the processing of the U-shaped iron body 4. When the T-shaped slider 86 slides in the T-shaped groove 82, because one side of the locking block 813 is set with an arc-shaped structure, the T-shaped slider 86 will squeeze the locking block 813. When squeezed, the limiting plate 814 and the compression spring 815 are compressed, causing the locking block 813 to embed into the interior of the base 1. When the locking block 813 is aligned with the slot 85, the compression spring 815 rebounds, thereby driving the locking block 813 to insert into the interior of the slot 85 to fix the T-shaped slider 86. When it is necessary to control the T-shaped slider 86 to reset, the adjusting block 812 in the sliding adjusting groove 811 is slidable. The adjusting block 812 drives the limiting plate 814 to slide and compresses the compression spring 815, while controlling the locking block 813 to slide out from the interior of the slot 85, thereby controlling the T-shaped slider 86 to reset.

[0036] The PLC controller 571 in this utility model is a previously disclosed technology, and the selected model is Siemens S7-300.

[0037] The infrared transmitter 573 in this utility model is a previously disclosed technology, and the selected model is VSLB9530S.

[0038] The infrared receiver 572 in this utility model is a previously disclosed technology, and the selected model is the TSOP33 series.

[0039] The working principle and usage process of this utility model are as follows: When processing the U-shaped iron, the hydraulic cylinder 51 is opened, causing the mounting plate 58 to descend. The descent of the mounting plate 58 causes the grinding wheel 54 to insert into the groove inside the U-shaped iron body 4. Then, the motor 56 is activated, and the motor 56 drives the drive shaft 55 to rotate via its output end. The rotation of the drive shaft 55 causes the grinding wheel 54 to process the U-shaped iron body 4. When the mounting plate 58 descends, it causes the telescopic rod 53 to extend, which in turn causes the buffer spring 52 to extend. This buffers the descent of the mounting plate 58 and improves its stability. As the mounting plate 58 descends, the infrared radiation emitted by the infrared transmitter 573 is received by the infrared receiver 572. When the mounting plate 58 descends to the groove inside the U-shaped iron body 4 where the grinding wheel 54 is inserted, the PLC controller 571 receives a signal and controls the hydraulic cylinder 51 to shut down and the motor 56 to start, thus automatically processing the U-shaped iron body 4. During processing, the entire U-shaped iron body 4 is first placed into the positioning groove. In step 2, the sliding positioning plate 83 then drives the T-shaped slider 86 inside the T-shaped groove 82 until the T-shaped slider 86 slides to the other end of the T-shaped groove 82. At this time, the positioning plate 83 can fix the upper edge of the U-shaped iron body 4, thus facilitating the processing of the U-shaped iron body 4. When the T-shaped slider 86 slides in the T-shaped groove 82, because one side of the locking block 813 is set with an arc structure, the T-shaped slider 86 will squeeze the locking block 813. After the locking block 813 is squeezed, it will compress the limiting plate 814 and the compression spring. Spring 815 causes the locking block 813 to be embedded inside the base 1. When the locking block 813 is aligned with the slot 85, the compression spring 815 rebounds, thereby driving the locking block 813 to be inserted into the slot 85 to fix the T-shaped slider 86. When it is necessary to control the T-shaped slider 86 to reset, the adjusting block 812 in the sliding adjusting groove 811 slides. The adjusting block 812 drives the limiting plate 814 to slide and compresses the compression spring 815. At the same time, it controls the locking block 813 to slide out from the slot 85, thereby controlling the T-shaped slider 86 to reset.
