Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices for iron tower parts, and particularly relates to an automatic grinding device for iron tower pads. Background Technology

[0002] The installation of steel towers requires numerous shims to support nuts or adjust the tower's verticality. These shims are rectangular plates cut from iron sheets. The edges of these shims are typically quite sharp after cutting. To prevent scratches to workers during installation, the edges need to be ground. Current technology involves workers holding the shims and pressing them against a grinding wheel, constantly adjusting their position to grind the edges. This method is not only inefficient but also generates high temperatures, affecting worker stability and posing a significant safety risk due to close contact with the grinding wheel, potentially causing abrasions. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic grinding device for iron tower blocks, which can automatically grind the edges of the blocks, avoiding the safety issues associated with manual grinding.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: An automatic grinding device for iron tower pads includes: A horizontally mounted plate with a through hole in its middle section along the vertical direction; The material storage assembly includes a limiting plate vertically disposed in the through hole, and four limiting plates are arranged in a circumferential array to limit the four sides of the pad block respectively. The upper and lower ends of the limiting plate protrude from the top and bottom surfaces of the mounting plate respectively. There are four grinding machines, all located below the mounting plate, with each machine positioned between adjacent limiting plates. Each grinding machine has a grinding head on its spindle, used to grind the four edges of the pad. The axis of the grinding head is located above the lower end face of the limiting plate, and the rotation direction of the grinding head in contact with the pad is upward. The minimum distance between the diagonally positioned grinding heads is less than the distance between the diagonals of the pad.

[0005] The beneficial effects of this utility model are as follows: This solution utilizes the weight of the pad to automatically move the pad towards the grinding head, thereby achieving automatic grinding, and can also achieve automatic material replenishment and automatic material discharge; it effectively prevents workers from having close contact with the grinding head, which not only improves the safety of grinding processing, but also grinds the four edges of the pad at the same time, which helps to improve grinding efficiency.

[0015] like Figures 1 to 3 As shown, an automatic grinding device for iron tower pad blocks includes: a mounting plate 1, a material storage assembly, and a grinding machine 3.

[0016] Mounting plate 1 is set horizontally, and a through hole 11 is opened in the middle along the vertical direction. The through hole 11 is a rectangular hole structure.

[0017] The material storage assembly includes a limiting plate 21 vertically disposed in the through hole 11, and the limiting plate 21 is respectively disposed on the four sides of the rectangular hole, and four limiting plates 21 are arranged in a circumferential array to limit the four sides of the pad block. The upper and lower ends of the limiting plate 21 protrude from the top and bottom surfaces of the mounting plate 1, respectively.

[0018] There are four grinding machines 3, all located below the mounting plate 1, and the four grinding machines 3 are respectively positioned between adjacent limiting plates 21. The main shaft of each grinding machine 3 is equipped with a grinding head 31, which is used to grind the four edges of the pad. The axis of the grinding head 31 is located above the lower end face of the limiting plate 21 to ensure that the pad is always within the rectangular cavity enclosed by the limiting plate 21 during the grinding process. This restricts the pad by the limiting plate 21 and prevents the pad from tilting or rotating during the grinding process. The rotation direction of the grinding head 31 in contact with the pad is upward. The minimum distance between the diagonally arranged grinding heads 31 is less than the distance between the diagonals of the pad. The difference between the two distances is the thickness of the material to be removed by grinding.

[0019] Before or during the grinding process, the pad is placed from above into the rectangular space enclosed by the four limiting plates 21, so that the pad is stacked in the rectangular space. Since the minimum distance between the grinding heads 31 set diagonally is less than the distance between the diagonal pads, the grinding heads 31 can be used to limit the pad and prevent the un-grinded pad from falling automatically.

[0020] The weight of the pad block itself will exert downward pressure on the grinding head 31. When grinding, starting the grinding machine 3 will drive the grinding head 31 to rotate rapidly. Since the side of the grinding head 31 used to grind the pad block rotates upwards, it is exactly opposite to the direction of the pressure exerted by the pad block on the grinding head 31, thus allowing the grinding head 31 to grind the pad block smoothly. As the grinding process continues, the edges of the pad block will be gradually ground from bottom to top, and the pad block will also automatically move downwards relative to the grinding head 31 under its own weight. After the entire edge of the pad block is ground, the pad block will automatically fall, achieving the purpose of automatic material discharge. The pad blocks stacked between the limiting plates 21 will also automatically fall, achieving automatic feeding. When grinding the last pad block, if there is concern that the pad block may not be heavy enough to prevent it from being ground smoothly, a rod can be used to apply downward pressure to the pad block, thereby assisting in the grinding process.

[0021] Preferably, the mounting plate 1 is a circular plate structure, the through hole 11 is coaxial with the mounting plate 1, and the limiting plate 21 and the grinding machine 3 are both arranged to move radially along the mounting plate 1 to accommodate pads of different widths, thereby increasing the practicality of the device.

[0022] Preferred, such as Figure 1 , Figure 2 As shown, the mounting plate 1 has a strip groove 12 in the middle of each of the four sides corresponding to the through hole 11, which communicates with the through hole 11. The middle section of the limiting plate 21 has a slider 211, which slides in the strip groove 12. The position of the limiting plate 21 can be adjusted by moving the slider 211 along the strip groove 12, so as to adapt to pads of different widths. More preferably, a screw can be inserted through the slider 211. After adjusting the position of the limiting plate 21, the slider 211 can be locked and fixed in the strip groove 12 by the screw, so as to achieve the purpose of fixing the limiting plate 21.

[0023] Further preferred, such as Figure 1 , Figure 2 As shown, an upper ring 22 is coaxially provided on the top surface of the mounting plate 1. The upper ring 22 is rotatably arranged around the axis. Four hinge rods 23 are arranged in a circumferential array on the inner ring of the upper ring 22. The front end of the hinge rod 23 is rotatably set on the upper ring 22. The ends of the four hinge rods 23 are respectively rotatably connected to four sliders 211. The rotation axes of both ends of the hinge rods 23 are parallel to the axis of the upper ring 22. By rotating the upper ring 22, the four limiting plates 21 can be moved along the strip groove 12 simultaneously through the four hinge rods 23. This structure achieves the purpose of synchronously adjusting the limiting plates 21, and the distance of movement of the limiting plates 21 is the same.

[0024] Preferred, such as Figure 3 As shown, the bottom surface of the mounting plate 1 is provided with guide rails 13 radially between adjacent limiting plates 21. Four grinding machines 3 are slidably mounted on the guide rails 13. The bottom surface of the mounting plate 1 is coaxially provided with a lower ring 32. The inner ring of the lower ring 32 is provided with four connecting rods 33 arranged in a circumferential array. The front end of the connecting rod 33 is rotatably mounted on the lower ring 32. The ends of the four connecting rods 33 are rotatably connected to the four grinding machines 3. The rotation axes of both ends of the connecting rods 33 are parallel to the axis of the lower ring 32. By rotating the lower ring 32, the four grinding machines 3 can be moved radially along the mounting plate 1 simultaneously through the four connecting rods 33. This structure achieves the purpose of synchronously adjusting the grinding machines 3, and the distance the grinding machines 3 are moved is the same.

[0025] In a further preferred embodiment, both the upper ring 22 and the lower ring 32 are fitted with locking screws. By tightening the locking screws, the positions of the upper ring 22 and the lower ring 32 on the mounting plate 1 can be fixed, thereby achieving the purpose of fixing the limiting plate 21 and the grinder 3.

[0026] Preferred, such as Figure 3As shown, the grinding head 31 has a conical structure with the top of the cone facing the middle of the mounting plate 1. The cone has a taper of 90 degrees. The angle between the outer walls of the two sides of the pad edge and the outer conical surface of the grinding head 31 is 45 degrees. This structure allows the axis of the grinding machine 3 to be parallel to the moving direction of the adjacent limiting plate 21, thus avoiding interference between the grinding machine 3 and the lower end of the limiting plate 21.

[0027] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
