Description

Technical Field

[0001] This invention relates to the field of workpiece grinding technology, and in particular to a universal grinding device for grinding oxide scale on the vertical surface of workpieces. Background Technology

[0002] When laser (or plasma, or flame) cutting steel plates, oxide scale is generated on the cut surface. This oxide scale is a processing residue that seriously affects the quality of subsequent welding and needs to be removed. Existing grinding heads, when grinding the sides of steel plates, only achieve a grinding effect when the grinding head moves close to the surface due to the directional nature of the workpiece's surface. The grinding head is driven by a drive mechanism, ensuring that its rotation is always in the same direction. A single grinding head can only grind one side of the workpiece, and its outer peripheral wall remains in contact with the workpiece's outer surface. The grinding head is driven by the drive mechanism to move slowly along the workpiece's side to complete the side grinding. However, during the grinding process, the workpiece exerts a reaction force on the grinding head, causing damage and affecting its service life. Summary of the Invention

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] To better understand the above technical solution, the following will provide a detailed explanation of the technical solution in conjunction with the accompanying drawings and specific testing methods.

[0034] Reference Figure 1As shown, a universal grinding device for oxide scale on the vertical surface of a workpiece according to the present invention includes: a frame 1; a magnetic conveying mechanism 2, disposed on the frame 1 for conveying the workpiece to be ground; a lifting mechanism 3, disposed on the frame 1 via a fixed bracket 4; a large revolution drive assembly 5, disposed on the lifting mechanism 3 via a lifting support 8; a small revolution drive assembly 6, driven by the large revolution drive assembly 5 to achieve horizontal rotation; and a grinding assembly 7, disposed on the small revolution drive assembly 6 and driven by the large revolution drive assembly 5. The grinding assembly 7 is driven simultaneously with the small revolution drive component 6 to achieve dual rotation; the grinding assembly 7 includes multiple grinding heads 71, each grinding head 71 including a grinding motor 711, a connecting shaft 712, a fixed base 713, a clearance shaft 714, and a grinding disc 715. The connecting shaft 712 is connected to the output shaft of the grinding motor 711 via a coupling 716; the clearance shaft 714 is obliquely disposed at the bottom end of the connecting shaft 712 via the fixed base 713, and the root of the grinding disc 715 is rotatably disposed on the outside of the clearance shaft 714, as shown below. Figure 5 As shown.

[0035] like Figure 2 As shown, the lifting mechanism 3 includes a motor 31, a chain synchronous transmission mechanism 100, and a lifting assembly. The lifting assembly includes four identical lifting devices: a first lifting device 32, a second lifting device 33, a third lifting device 34, and a fourth lifting device 35. The output shaft of the motor 31 is connected to the first lifting device 32 via the chain synchronous transmission mechanism 100. The first lifting device 32 and the second lifting device 33 are driven by a first connecting rod 36, and the third lifting device 34 and the fourth lifting device 35 are driven by a second connecting rod 37. The second lifting device 33 and the fourth lifting device 35 are connected by the chain synchronous transmission mechanism 100. When the motor 31 starts, it drives the four lifting devices to move simultaneously through the chain synchronous transmission mechanism, thereby controlling the grinding assembly 7 to contact or move away from the workpiece to be ground.

[0036] As a further improvement of the present invention, a tensioning wheel 38 is also provided on the chain synchronous transmission mechanism 100 between the second lifting device 33 and the fourth lifting device 35. The tensioning wheel 38 is mounted on the fixed bracket 4 via a support seat 39. The tensioning wheel 38 is used to tension the chain synchronous transmission mechanism 100 to prevent the chain on the chain synchronous transmission mechanism 100 from becoming loose and affecting the transmission effect.

[0037] like Figure 3As shown, the lifting device 32 includes a lifting rod 321, a rotating rod 322, a first bevel gear, and a second bevel gear. The bottom end of the lifting rod 321 is connected to the lifting support base 8. The rotating rod 322 is connected to the output shaft of the motor 31 via a chain synchronous transmission mechanism 100. The first bevel gear is mounted on the lifting rod 321, and the second bevel gear is mounted on the rotating rod 322. The first bevel gear and the second bevel gear mesh. When the motor 31 starts, the rotating rod 322 rotates, and the meshing of the two bevel gears drives the lifting rod 321 to achieve vertical lifting, thereby controlling the lifting support base 8 to move up and down.

[0038] In this embodiment, the four lifting devices are provided with protective shells on their outer sides, which can enclose the lifting rod 321, bevel gear one, and bevel gear two.

[0039] like Figure 4 As shown, the large revolution drive assembly 5 includes a large revolution motor 51, a chain synchronous transmission mechanism 100, a large revolution shaft 52, and a large revolution disk 53. The top end of the large revolution shaft 52 is rotatably connected to the lifting support base 8, and the bottom end of the large revolution shaft 52 is connected to the large revolution disk 53. The output shaft of the large revolution motor 51 is connected to the large revolution shaft 52 through the chain synchronous transmission mechanism 100.

[0040] The chain synchronous transmission mechanism 100 described in this embodiment includes a driving gear, a driven gear, and a chain, wherein the driving gear and the driven gear are driven by the chain.

[0041] The small revolution drive assembly 6 includes a small revolution motor 61, a small revolution shaft 62, and a small revolution disk 63. The small revolution motor 61 is mounted on the large revolution disk 53. The output shaft of the small revolution motor 61 is connected to the top end of the small revolution shaft 62, and the bottom end of the small revolution shaft 62 is connected to the small revolution disk 63.

[0042] like Figure 8 As shown, the magnetic conveying mechanism 2 includes a feeding motor 21, a drive roller 22, a driven roller 23, a conveyor belt 24, a support frame 25, and a magnetic platform 26. The output shaft of the feeding motor 21 is connected to the drive roller 22. The conveyor belt 24 is located outside the drive roller 22 and the driven roller 23. The magnetic platform 26 is mounted at the bottom of the conveyor belt 24 via the support frame 25. The design of the magnetic platform 25 allows the workpiece to be attracted to the conveyor belt 24, preventing it from shifting during the grinding process.

[0043] like Figure 5As shown, the bottom of the connecting shaft 712 is provided with a connecting seat 7121 for mounting a fixing seat 713. The connecting seat 7121 has several inclined mounting surfaces 7122. The fixing seat 713 is disposed on the inclined mounting surfaces 7122, and the clearance rotating shaft 714 is parallel to the inclined mounting surfaces 7122. Preferably, the fixing seat 713 is a U-shaped seat. The U-shaped seat has mounting holes and rotating shaft mounting holes. The U-shaped seat is locked and fixed to the connecting seat 7121 by fasteners, and the clearance rotating shaft 714 is rotatably mounted in the rotating shaft mounting holes.

[0044] like Figure 6 As shown, the grinding disc 715 includes a wire fixing block 7151 and a wire brush block 7152 composed of multiple strands of steel wire. The wire fixing block 7151 is provided with a rotating connection part 7153 and a mounting groove. The root of the wire brush block 7152 is fixed in the mounting groove, and the length of the wire brush block 7152 gradually shortens along the direction away from the magnetic conveying mechanism 2. This design makes the tail end of the wire brush block 7152 inclined, and only the head of the wire brush block 7152 contacts the vertical surface of the workpiece to strike the oxide scale on the workpiece, reducing the impact area between the wire brush block 7152 and the workpiece, further reducing the reaction force of the workpiece on the wire brush block 7152, effectively avoiding damage to the grinding disc 715, greatly extending the service life of the grinding head 71, and ensuring the grinding effect.

[0045] During operation, the large revolution drive assembly 5 and the small revolution drive assembly 6 drive the grinding assembly 7 to rotate in a dual manner, controlling the grinding head 71 to move in multiple directions instead of always moving in one direction. This enables omnidirectional grinding of multiple surfaces of the workpiece. While rotating, the grinding disc 715 swings around the avoidance axis 714 to avoid the workpiece, allowing the grinding disc 715 to slide over the upper surface of the workpiece. The grinding disc 715 then strikes and grinds the side of the workpiece to remove oxide scale, reducing the reaction force of the workpiece on the grinding disc 715 and effectively improving the service life of the grinding disc 715. The workpiece is conveyed on the magnetic conveying mechanism 2. When the workpiece passes through the grinding area, the grinding disc 715 grinds the vertical (side) surfaces of the workpiece while avoiding the workpiece, allowing the workpiece to pass smoothly through the grinding area. This simultaneous conveying and grinding greatly improves grinding efficiency.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
