The four iron blocks 8 are matched with four electromagnetic components respectively. The four electromagnetic components all include a frame body 31. The four frame bodies 31 are respectively fixedly connected in the two main tilt adjustment frames 4 and the two auxiliary tilt adjustment frames 5. The four frame bodies 31 are all fixedly connected with conductor posts 32, and spiral wires 33 are all wound around the four conductor posts 32. The four spiral wires 33 are all equipped with external lead wires 34. Through the design of the base, a mounting structure of the main clamping structure and the auxiliary support structure is formed, which ensures that the main clamping structure and the auxiliary support structure are used normally while improving the coupling effect between the two. The practicality is further enhanced. The main downward bending mounting frame 2 and the auxiliary downward bending mounting frame 3 are both slidably connected to two sliding adjustment frames 51, and the main downward bending mounting frame 2 and the auxiliary downward bending mounting frame 3 are both rotatably connected to two adjustment threaded rods 52. The four adjusting threaded rods 52 are respectively threadedly connected to the four sliding adjustment frames 51, and the two main adjusting springs 6 and the two auxiliary adjusting springs 7 are respectively fixedly connected to the four sliding adjustment frames 51, so as to facilitate the adjustment of the relative distance between the two main oblique adjustment frames 4 and the relative distance between the two auxiliary oblique adjustment frames 5.

The two main downward bending mounting frames 2 and the two auxiliary downward bending mounting frames 3 are each provided with two operating notches 55, and the four operating notches 55 are respectively used for the auxiliary adjustment operations of the four auxiliary rotating frames 53.

[0043] It should be further explained that the top of the frame bracket 1 is equipped with a finishing auxiliary component, which includes a cross-mounting frame 21. The top of the frame bracket 1 is fixedly connected to two track frames 22, and the two track frames 22 are slidably connected to the sliding frames 23. The two sliding frames 23 are fixedly connected to the cross-mounting frame 21. A displacement servo motor 24 is installed on the cross-mounting frame 21. A displacement gear 56 is installed on the output shaft of the displacement servo motor 24. The displacement gear 56 is matched with a displacement rack 57. The displacement rack 57 is fixedly installed on the top of the frame bracket 1. The displacement servo motor 24 is used to cross the mounting frame 21 relative to the front of the frame bracket 1. After the adjustment, a feed electric telescopic rod 25 is installed on the cross-mounting frame 21, and a sliding sleeve 26 is installed on the telescopic rod of the feed electric telescopic rod 25.

A pressure sensor is installed in the sliding sleeve 26, and a detection surface matching the center rod 30 is arranged at the bottom end of the pressure sensor. When in use, the detection information of the pressure sensor is connected to the external intelligent control terminal. When the external lead wire 34 is connected to the intelligent control terminal, the current size in the spiral wire 33 can be adjusted in accordance with the detection value of the matching pressure sensor. When the machining feed force of the finishing tool 28 on the forklift accessory rod head is large, that is, the relative force of the finishing tool 28 on the forklift accessory rod head is large, the corresponding detection value of the pressure sensor is also large, and the current value in the spiral wire 33 is also large, thereby increasing the magnetic attraction of the electromagnetic component on the iron block 8. This will cause the two main oblique adjustment frames 4 to move downward relative to the main lower bending mounting frame 2, and will also cause the two auxiliary oblique adjustment frames 5 to move relative to the auxiliary lower bending mounting frame 2. The bent mounting frame 3 is driven downward, and then the relative positions of the two support shafts 9 are brought closer, thereby increasing the supporting strength of the two fixed support rollers 11 and the multiple auxiliary support rollers 12 relative to the forklift accessory rod head, ensuring that the forklift accessory rod head has sufficient auxiliary supporting effect during the fine machining process, reducing the machining deformation of the forklift accessory rod head, and when the machining feed force of the fine machining tool 28 acting on the forklift accessory rod head is small, the supporting strength of the two fixed support rollers 11 and the multiple auxiliary support rollers 12 relative to the forklift accessory rod head is reduced, thereby reducing the occurrence of support deformation of the forklift accessory rod head caused by excessive supporting force.

[0044] It should be further explained that the auxiliary support structure includes two support shafts 9, the rear ends of the two support shafts 9 are respectively rotatably connected to the two main oblique adjustment frames 4, the two auxiliary oblique adjustment frames 5 are each provided with a rotating hole, the two support shafts 9 are respectively rotatably connected in the two rotating holes, the front ends of the two auxiliary oblique adjustment frames 5 are each installed with a cooperative servo motor 10, the output shafts of the two cooperative servo motors 10 are respectively transmission-connected to the two support shafts 9, the two support shafts 9 are each fixedly connected with a fixed support roller 11, and the two support shafts 9 are each installed with a plurality of auxiliary support rollers 12. Through the design of the auxiliary support structure, a covering support structure is formed by matching the forklift accessory rod head, which can be combined with the actual situation of fine machining to form a full-coverage positioning, and the positioning effect is further improved. Power systems are installed in the plurality of auxiliary support rollers 12, and the plurality of power systems include a built-in servo motor 35. A spur gear 36 is installed on the output shaft of the plurality of built-in servo motors 35, and the plurality of built-in servo motors 35 are respectively installed in the plurality of auxiliary support rollers 12. A stepped notch 37 is provided on the two support shafts 9. Each stepped notch 37 is fixedly connected with a recessed rack 38, and a plurality of spur gears 36 are respectively meshed with the two recessed racks 38. An embedding groove is provided on the two support shafts 9, and a feed electrode strip 39 and a return electrode strip 40 are embedded and installed in the two embedding grooves. The two feed electrode strips 39 are each equipped with a plurality of feed connection electrodes 41, and the two return electrode strips 40 are each equipped with a plurality of return connection electrodes 42. The plurality of feed connection electrodes 41 are respectively installed in a plurality of auxiliary support rollers 12, and the plurality of return connection electrodes 42 are respectively installed in a plurality of auxiliary support rollers 12. The feed electrode 41 and the return electrode 42 located in the auxiliary support roller 12 are electrically connected to the built-in servo motor 35 in the auxiliary support roller 12, and the return electrode ring 43 and the feed electrode ring 44 are fixedly connected in the rotating hole.

The guide sleeve 49 is inside A guide rod 50 is slidably connected, and the guide rod 50 is fixedly connected between the main downward bending mounting frame 2 and the auxiliary downward bending mounting frame 3.

The two direct-drive servo motors 20 are respectively used for the rotation drive of the two main shaft frames 18. Through the design of the main clamping structure, the rod heads at both ends of the matching forklift accessory rod head form corresponding clamping structures to facilitate the auxiliary positioning of the finishing operation link of the forklift accessory rod head and the necessary rotation movement drive.
