Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and in particular to a follow-up adaptive online fully automatic grinding device for large-diameter circular workpieces. Background Art

[0002] The roller press is designed based on the principle of bed grinding. It consists of two synchronously rotating extrusion rollers—one fixed and one movable—rotating in opposite directions. Key features include high pressure, full speed, full material, and bed crushing. Material is fed from above the rollers and continuously drawn between them. Subjected to high pressures of 100-150 MPa, it is transformed into a dense cake and discharged from the bottom of the machine. Roller wear is a combination of high-stress abrasive wear on the roller surface and fatigue wear in the subsurface layer. Shallow cracks typically develop about 10 mm from the roller surface, while deeper cracks can extend 20-30 mm, sometimes reaching 50-60 mm in depth. With extended use, cracks extend outward along the circumference of the roller, causing partial or complete peeling of the roller. In addition to normal wear, foreign metal objects such as bolts and iron blocks entering the material bed can also damage the roller surface, requiring repair. Drilled, glued, and inlaid carbide stud rollers with clearance fit are also a type of stud roller.

[0003] After searching, the patent with application number CN202310584958.9 discloses "a method for surfacing welding of stud wheels and a welding device thereof", including a welding robot and a portal frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the sliding plate is driven to slide to the left (in the direction of the stud roller) on the bottom plate by rotating the threaded rod, and the sliding plate drives the fixed plate, the rotating motor and the rotating frame to slide to the left synchronously, and the rotating frame drives the hydraulic cylinder and the grinding motor to move synchronously, and then the rotating motor is started to drive the rotating frame, the hydraulic cylinder, the connecting plate and the grinding motor to rotate synchronously, so that the grinding block is aligned with the stud to be ground after welding, and the hydraulic cylinder is started to drive the grinding motor to approach the stud to be ground, and at the same time, the grinding motor is started to drive the grinding block to rotate, and the grinding block contacts the stud, which is convenient for grinding the redundant part of the stud after welding, thereby ensuring the automatic grinding of the studs on the stud roller, improving work efficiency and saving labor.

[0021] When the cam is in contact with the guide rail, the two guide rails are in contact with each other, and the two guide rails are in contact with each other, so that the guide rails are in contact with each other, and the two guide rails are in contact with each other, so that the guide rails are in contact with each other, and the two guide rails are in contact with each other, so that the guide rails are in contact with each other, and the two guide rails are in contact with each other, so that the guide rails are in contact with each other, and the two guide rails are in contact with each other, so that the guide rails are in contact with each other,

[0022] When the cam limit plate is moved closer to the clamping pin, the front end of the cam limit plate will be in contact with the cam roller, and as the connecting plate, bracket and grinding motor continue to move forward, the support rod and the cam limit plate will slide adaptively on the bracket, and the compression spring 2 will be compressed. When the cam limit plates on both sides are close to each other to clamp the cam limit plate, the magnetic strip will move synchronously, and the magnetic strip will pass the lower side of the magnetic block rod. Under the action of magnetic repulsion, the magnetic strip and the cam limit plate will rotate on the support rod, and the compression spring 1 will facilitate the cam limit plate to clamp the cam limit plate, adaptively avoid the excess welding slag protrusion on the surface of the cam limit plate, and avoid the situation that the cam limit plate is normally and stably clamped on the surface of the cam limit plate. In addition, the through groove also reduces the clamping area between the cam limit plate and the surface of the cam limit plate, thereby reducing the situation that the cam limit plate is clamped on the welding slag protrusion, thereby ensuring the subsequent grinding quality of the cam limit plate.

[0023] 4. In the present invention, after the arc-surface limit plate has completed clamping the column nail, the electric push rod is started to drive the anti-drop blocks on both sides to approach each other, so that the anti-drop blocks are clamped and fixed on the surface of the column nail. The anti-drop blocks and oblique grooves are convenient for limiting the column nail. The oblique grooves will be stuck on the texture of the outer surface of the column nail, reducing the excessive pressure of the grinding block on the column nail, which causes the glued column nail to sink into the inside of the column nail roller and become unstable after grinding, thereby ensuring that the column nail will not be affected in normal use after grinding.

[0024] 5. In the present invention, when the anti-drop blocks are close to each other and clamp the column nail, the positioning hole will maintain the same level as the positioning rod. When the connecting plate moves forward, it will also drive the positioning rod to move forward synchronously, so that when the grinding block grinds the column nail, the positioning rod will also be inserted into the positioning hole, avoiding the failure of the anti-drop blocks on both sides to collapse outward when the column nail is subjected to excessive pressure from the grinding block, thereby ensuring the firm clamping of the anti-drop blocks.

[0025] 6. In the present invention, when the turret rotates, it also drives the guide rod to rotate in the stabilizing ring, thereby ensuring the stability of the turret when rotating to adjust the angle of the grinding motor.

[0026] 7. In the present invention, the starting cylinder drives the stabilizing plate to approach the stabilizing ring, and the stabilizing plate is tightly abutted against the stabilizing ring, ensuring the stability of the grinding motor when grinding the studs when the rotating frame is stationary, thereby ensuring the grinding quality of the studs.

[0027] 8. In the present invention, the connecting rod is pulled outward to separate the clamping plate from the fixed plate, and then the fixed plate is slid out of the slide plate to disassemble the entire grinding device, which facilitates the convenient disassembly and assembly of the grinding device without affecting the normal use of the post nail roller after grinding.

The rear end of the arc limit piece 7 is slidably installed with an anti-drop block 17, and the anti-drop block 17 is provided with an oblique slot 1701 at the end close to each other to prevent the drop. An electric push rod 18 is fixedly installed on the upper end of the block 17, and the electric push rod 18 is fixedly connected to the end away from the arc limit piece 7. The front end of the connecting plate 4 is fixedly installed with a positioning rod 19 symmetrically on the left and right, and a positioning hole 20 is opened on the middle part of the anti-drop block 17 corresponding to the positioning rod 19. A guide rod 23 is fixedly installed on the front side of the right end of the rotating frame 6, and a stabilizing ring 24 is fixedly installed on the left end of the fixed plate 22 corresponding to the guide rod 23.

A cylinder 26 is fixedly installed on the front side of the left end of the rotating frame 6, and a stabilizing plate 25 is fixedly installed on the right end of the cylinder 26 corresponding to the stabilizing ring 24;

[0044] During operation, the threaded rod 28 is rotated to drive the slide plate 27 to slide to the left (pole roller 2) on the bottom plate 1, and the slide plate 27 drives the fixed plate 22, the rotating motor 21 and the rotating frame 6 to slide to the left synchronously, and the rotating frame 6 drives the hydraulic cylinder 5 and the grinding motor 3 to move synchronously, and then the rotating motor 21 is started to drive the rotating frame 6, the hydraulic cylinder 5, the connecting plate 4 and the grinding motor 3 to rotate synchronously, so that the grinding block is aligned with the column nail to be ground after welding, and the hydraulic cylinder 5 is started to drive the grinding motor 3 to approach the column nail to be ground, and at the same time, the grinding motor 3 is started to drive the grinding block to rotate, and the grinding block contacts the column nail, which is convenient for grinding the excess part of the column nail after welding, thereby ensuring the automatic grinding of the column nail on the column nail roller 2, improving work efficiency and saving labor. At the same time, when the connection When the plate 4 moves toward the column nail direction, it will also drive the bracket 12, the passive rod 15, the support rod 8, and the cambered surface limiting piece 7 to move synchronously, and the passive rod 15 will be squeezed by the inclined thrust of the inclined block plate 16, forcing the passive rods 15, the bracket 12, the support rod 8 and the cambered surface limiting piece 7 on both sides to approach each other synchronously, and the bracket 12 will slide on the connecting plate 4, compressing the spring three 14, and the cambered surface limiting piece 7 will gradually clamp the two sides of the column nail to be ground, and when the first grinding block contacts the grinding column nail, it will first abut and be clamped on the surface of the column nail roller 2. After clamping is completed, the passive rod 15 just slides to the horizontal surface of the side where the inclined block plate 16 is close to each other, and will not continue to push the passive rods 15, the bracket 12, the support rod 8 and the cambered surface limiting piece 7 on both sides to approach each other, thereby making the cambered surface limiting piece 7 The side of the positioning pieces 7 that are close to each other will clamp and limit the two sides of the column nail, avoiding the situation that when the subsequent grinding block grinds the column nail, the excess irregular welding materials on the column nail are squeezed and pushed to tilt and deflect, and then deform, thereby ensuring the quality of the column nail grinding. After the column nail is clamped and limited, the front end of the arc-shaped limiting piece 7 will abut and fit on the column nail roller 2. As the connecting plate 4, bracket 12, and grinding motor 3 continue to move forward, the support rod 8 and the arc-shaped limiting piece 7 will slide adaptively on the bracket 12, compressing the spring 2 13. When the arc-shaped limiting pieces 7 on both sides are close to each other to clamp the column nail, the magnetic strip 10 will be driven to move synchronously. The magnetic strip 10 will pass the lower side of the magnetic block rod 11, and under the action of the magnetic repulsion, it will drive The magnetic strip 10 and the arc-surface limiting piece 7 rotate on the support rod 8 and compress the spring 19, so that when the arc-surface limiting piece 7 clamps the column nail, it adaptively avoids the excess welding slag protrusions on the surface of the column nail, thereby avoiding the situation that the arc-surface limiting piece 7 is normally and stably clamped on the surface of the column nail. In addition, the through groove 701 provided also reduces the clamping area between the arc-surface limiting piece 7 and the surface of the column nail, thereby also reducing the situation that the arc-surface limiting piece 7 is clamped on the welding slag protrusion, thereby ensuring the subsequent grinding quality of the column nail. When the arc-surface limiting piece 7 has completed clamping the column nail, the electric push rod 18 is started to drive the anti-drop blocks 17 on both sides to approach each other, so that the anti-drop blocks 17 are clamped and fixed on the surface of the column nail. The anti-drop blocks 17 and the oblique slots 1701 are convenient for limiting the column nail.The oblique slot 1701 will be stuck on the texture of the outer surface of the column nail, reducing the excessive pressure of the grinding block on the column nail, which will cause the glued column nail to sink into the inside of the column nail roller 2 and become unstable after grinding, thereby ensuring that the column nail will not be affected in normal use after grinding. When the anti-drop blocks 17 are close to each other and clamp the column nail, the positioning hole 20 will be kept at the same level as the positioning rod 19. When the connecting plate 4 moves forward, it will also drive the positioning rod 19 to move forward synchronously, so that when the grinding block grinds the column nail, the positioning rod 19 will also be inserted into the positioning hole 20, avoiding the failure of the anti-drop blocks 17 on both sides to limit the column nail when the column nail is subjected to excessive pressure from the grinding block, resulting in the failure of the anti-drop blocks 17 on both sides to collapse outward, thereby ensuring the firm clamping of the anti-drop blocks 17. When the rotating frame 6 rotates, it will also drive the guide rod 23 to rotate in the stabilizing ring 24, ensuring the stability of the rotating frame 6 when rotating to adjust the angle of the grinding motor 3.

[0045] As an embodiment of the present invention, a disassembly and assembly mechanism for quickly disassembling and assembling the fixed plate 22 is further provided. The disassembly and assembly mechanism includes a slide plate 27 slidably mounted on the lower end of the fixed plate 22. The lower end of the slide plate 27 is slidably mounted on the base plate 1. A threaded rod 28 is threadedly mounted on the middle portion of the slide plate 27. The threaded rod 28 is rotatably mounted on the base plate 1. A clamping plate 29 is abutted against the lower side of the rear end of the fixed plate 22. A connecting rod 30 is fixedly mounted on the right end of the clamping plate 29. The middle portion of the connecting rod 30 passes through and is slidably mounted on the slide plate 27. A spring 4 31 is sleeved on the outer side of the connecting rod 30.

[0046] During operation, the cylinder 26 is started to drive the stabilizing plate 25 to approach the stabilizing ring 24. The stabilizing plate 25 is tightly abutted against the stabilizing ring 24, ensuring the stability of the grinding motor 3 when grinding the studs when the rotating frame 6 is stationary, thereby ensuring the grinding quality of the studs. The connecting rod 30 is pulled outward to drive the clamping plate 29 to separate from the fixed plate 22, and then the fixed plate 22 is slid out of the slide plate 27, and the entire grinding device can be disassembled, which is convenient for the disassembly and assembly of the grinding device and will not affect the normal use of the stud roller 2 after grinding.

[0047] Working principle:

[0048] When the present invention is used, the threaded rod 28 is rotated to drive the slide plate 27 to slide in the left direction (towards the nail roller 2) on the bottom plate 1, and the slide plate 27 drives the fixed plate 22, the rotating motor 21 and the rotating frame 6 to slide to the left synchronously, and the rotating frame 6 drives the hydraulic cylinder 5 and the grinding motor 3 to move synchronously, and then the rotating motor 21 is started to drive the rotating frame 6, the hydraulic cylinder 5, the connecting plate 4 and the grinding motor 3 to rotate synchronously, so that the grinding block is aligned with the nail to be ground after welding, and the hydraulic cylinder 5 is started to drive the grinding motor 3 to approach the nail to be ground, and at the same time, the grinding motor 3 is started to drive the grinding block to rotate, and the grinding block contacts the nail, which is convenient for grinding the redundant part of the nail after welding, thereby ensuring the automatic grinding of the nail on the nail roller 2, improving work efficiency, and saving labor. At the same time, when When the connecting plate 4 moves toward the column nail direction, it will also drive the bracket 12, the passive rod 15, the support rod 8, and the arc surface limiting piece 7 to move synchronously, and the passive rod 15 will be squeezed by the inclined thrust of the inclined block plate 16, forcing the passive rod 15, the bracket 12, the support rod 8 and the arc surface limiting piece 7 on both sides to approach each other synchronously, and the bracket 12 will slide on the connecting plate 4, compressing the spring three 14, and the arc surface limiting piece 7 will gradually clamp the two sides of the column nail to be ground, and when the first grinding block contacts the grinding column nail, it will first abut and be clamped on the surface of the column nail roller 2. After clamping is completed, the passive rod 15 just slides to the horizontal surface of the side where the inclined block 16 is close to each other, and will not continue to push the passive rod 15, the bracket 12, the support rod 8 and the arc surface limiting piece 7 on both sides to approach each other, thereby making the arc surface The side where the limiting pieces 7 are close to each other will clamp and limit the two sides of the column nail, avoiding the situation that when the subsequent grinding block grinds the column nail, the excess irregular welding materials on the column nail are squeezed and pushed to tilt and deflect, and then deform, thereby ensuring the quality of the column nail grinding. After the column nail is clamped and limited, the front end of the arc-shaped limiting piece 7 will abut and fit on the column nail roller 2. As the connecting plate 4, bracket 12, and grinding motor 3 continue to move forward, the support rod 8 and the arc-shaped limiting piece 7 will slide adaptively on the bracket 12, compressing the spring 2 13. When the arc-shaped limiting pieces 7 on both sides are close to each other to clamp the column nail, the magnetic strip 10 will be driven to move synchronously. The magnetic strip 10 will pass the lower side of the magnetic block rod 11 and, under the action of the magnetic repulsion, will drive The magnetic strip 10 and the arc-surface limiting piece 7 rotate on the support rod 8 and compress the spring 19, so that when the arc-surface limiting piece 7 clamps the column nail, it adaptively avoids the excess welding slag protrusions on the surface of the column nail, thereby avoiding the situation that the arc-surface limiting piece 7 is normally and stably clamped on the surface of the column nail. In addition, the through groove 701 provided also reduces the clamping area between the arc-surface limiting piece 7 and the surface of the column nail, thereby also reducing the situation that the arc-surface limiting piece 7 is clamped on the welding slag protrusion, thereby ensuring the subsequent grinding quality of the column nail. When the arc-surface limiting piece 7 has completed clamping the column nail, the electric push rod 18 is started to drive the anti-drop blocks 17 on both sides to approach each other, so that the anti-drop blocks 17 are clamped and fixed on the surface of the column nail. The anti-drop blocks 17 and the oblique slots 1701 are convenient for limiting the column nail.The oblique slot 1701 will be stuck on the texture of the outer surface of the column nail, reducing the excessive pressure of the grinding block on the column nail, which will cause the glued column nail to sink into the inside of the column nail roller 2 and become unstable after grinding, thereby ensuring that the column nail will not be affected in normal use after grinding. When the anti-drop blocks 17 are close to each other and clamp the column nail, the positioning hole 20 will be kept at the same level as the positioning rod 19. When the connecting plate 4 moves forward, it will also drive the positioning rod 19 to move forward synchronously, so that when the grinding block grinds the column nail, the positioning rod 19 will also be inserted into the positioning hole 20, avoiding the anti-drop blocks 17 on both sides from failing to limit when the column nail is subjected to excessive pressure from the grinding block, resulting in the anti-drop blocks 17 on both sides collapsing and failing, thereby ensuring the anti-drop The block 17 is firmly clamped. When the rotating frame 6 rotates, it also drives the guide rod 23 to rotate in the stabilizing ring 24, ensuring the stability of the rotating frame 6 when adjusting the angle of the grinding motor 3. After the adjustment is completed, the cylinder 26 is started to drive the stabilizing plate 25 to move closer to the stabilizing ring 24. The stabilizing plate 25 is tightly abutted against the stabilizing ring 24, ensuring the stability of the grinding motor 3 when grinding the studs when the rotating frame 6 is stationary, thereby ensuring the grinding quality of the studs. The connecting rod 30 is pulled outward to drive the clamping plate 29 to separate from the fixed plate 22, and then the fixed plate 22 is slid out of the slide 27 to disassemble the entire grinding device, which is convenient for the convenient disassembly and assembly of the grinding device and will not affect the normal use of the stud roller 2 after grinding.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
