Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a flat processing device for mechanically processed parts. Background Art

[0002] The flattening of machined parts refers to a treatment of the workpiece surface during the machining process, which aims to eliminate or reduce the unevenness of the workpiece surface and improve its machining accuracy and surface quality. The role of flattening is mainly reflected in the following aspects: 1. Through flattening, the defects such as ripples, depressions, and protrusions on the workpiece surface can be eliminated or reduced, thereby improving the dimensional accuracy and shape accuracy of the workpiece; 2. Flattening can make the workpiece surface smoother and reduce surface roughness, which is particularly important for improving the fatigue strength and corrosion resistance of parts; 3. The surface of the workpiece after flattening is more uniform, which helps to improve the mechanical properties of the material, such as improving hardness, toughness and fatigue fracture resistance; 4. Flattening can be used as a preparation for subsequent processing procedures. By pre-flattening the workpiece surface, the adjustment and correction during subsequent processing can be reduced, thereby improving production efficiency; 5. Some parts in the field of precision machinery or aerospace have extremely high requirements for surface flatness, and flattening can meet these special technical requirements; 6. Flattening can reduce subsequent surface treatment procedures such as grinding and polishing, reducing production costs and processing time.

[0003] For example, a flattening device for machined parts disclosed in a Chinese patent document (Announcement No.: CN219234910U) starts the micro motor on the top of the connecting plate through a controller. At this time, the micro motor drives the rotating shaft to rotate. The rotating shaft and the nylon rope are used in conjunction to move the transmission rod upward. The transmission rod and the slide rod are used in conjunction to drive the lifting plate between the connecting plates to move. At this time, the height of the workpiece can be adjusted to prevent the grinding wheel from colliding with the limit block and causing damage to the flattening device.

[0004] However, it only bears the gravity of the lifting plate and the workpiece through the nylon rope. When the mass of the workpiece is large, the lifting plate will be suspended in the air for too long, which will cause the nylon rope to break due to the long-term force, resulting in low processing efficiency, damage to the leveling processing equipment and safety hazards to surrounding personnel.

[0028] The outer surface of the bidirectional threaded shaft 4 is threadedly sleeved with symmetrically distributed moving blocks 6, and the two side surfaces of the moving blocks 6 are respectively in contact with the inner walls on both sides of the moving groove 5. The threads of the bidirectional threaded shaft 4 are bidirectionally symmetrically distributed. When the servo motor 3 is started, the servo motor 3 drives the bidirectional threaded shaft 4 to rotate, thereby driving the two moving blocks 6 to move toward each other.

[0029] A movable plate 7 is fixedly connected to the upper surface of the movable block 6, a slide groove 8 is provided on the upper surface of the movable plate 7, a height adjustment block 9 is slidably sleeved on the inner wall of the slide groove 8, and the height adjustment block 9 is respectively provided with a low upper surface 10, a slope 11 and a high upper surface 12. The setting of the slope 11 can adjust the height of the limit clamp 21, so that the height can be adjusted according to the specific conditions of different workpieces, and the adaptability is stronger.

[0030] A force-bearing push plate 13 is fixedly connected to one side surface of the height adjustment block 9, and a mounting plate 14 is fixedly connected to the upper surface of the movable plate 7. A height adjustment groove 15 is provided on one side surface of the mounting plate 14, and one end of the height adjustment groove 15 passes through and extends to the other side surface of the mounting plate 14. A hydraulic cylinder piston rod 16 is fixedly installed on the inner wall of the mounting plate 14, and one end of the hydraulic cylinder piston rod 16 is fixedly connected to one side surface of the force-bearing push plate 13. The hydraulic cylinder piston rod 16 pushes the height adjustment block 9 to move through the force-bearing push plate 13. The movement of the height adjustment block 9 makes the adjusting wheel 19 no longer contact with the high upper surface 12 of the height adjustment block 9, but contacts with the inclined surface of the height adjustment block 9 under the action of gravity, so that the height of the limit clamp 21 is adjusted through the square column 18 and the connecting rod 20.

[0031] A limiting plate 17 is fixedly connected to the surface of one side of the mounting plate 14, and a square column 18 is slidably sleeved on the inner wall of the limiting plate 17. Under the limiting action of the limiting plate 17, the square column 18 can only move in the up and down directions. An adjusting wheel 19 is connected to one end of the square column 18 through a pin shaft, and the outer surface of the adjusting wheel 19 contacts the high upper surface 12 of the height adjusting block 9. When the height adjusting block 9 moves, the height of the adjusting wheel 19 is adjusted by the ramp 11, thereby adjusting the height of the limiting clamp 21.

[0033] One end of the connecting rod 20 is fixedly connected to a limit clamp 21, and the servo motor 3 drives the moving block 6 to move toward each other through the bidirectional threaded shaft 4, thereby driving the limit clamp 21 to move toward each other to clamp the workpiece. The upper surface of the base 1 is fixedly connected to a processing table 22, and the upper surface of the base 1 is fixedly installed with a leveling processing device body 23.

[0034] By setting the height adjustment block and the height adjustment wheel, the height of the limit clamp can be adjusted according to the specific conditions of different workpieces, effectively preventing the collision between the grinding wheel and the limit clamp, which may cause damage to the leveling processing device. In addition, the processing table is fixedly connected to the base and will not be damaged due to long-term stress. This improves the processing efficiency, effectively prevents damage to the leveling processing device, and reduces safety hazards for surrounding workers.

[0035] Working principle: Step 1, place the workpiece on the upper surface of the processing table 22, observe the height between the upper surface of the limit clamp 21 and the upper surface of the workpiece, if it is found that the height of the upper surface of the limit clamp 21 is higher than the upper surface of the workpiece, during the leveling process, it may cause the grinding wheel to collide with the limit clamp 21, resulting in damage to the leveling processing device, at this time, the height of the limit clamp 21 can be adjusted, the hydraulic cylinder piston rod 16 is started, and the height adjustment block 9 is pushed to move through the force-bearing push plate 13, and the movement of the height adjustment block 9 makes the adjusting wheel 19 no longer contact with the high upper surface 12 of the height adjustment block 9, but contacts with the inclined surface of the height adjustment block 9 under the action of gravity, so that the height of the limit clamp 21 is reduced through the square column 18 and the connecting rod 20, and the height between the upper surface of the limit clamp 21 and the upper surface of the workpiece is observed again. If it is found that the height of the upper surface of the limit clamp 21 is lower than the upper surface of the workpiece, the hydraulic cylinder piston rod 16 can be stopped, and at this time, during the leveling process, the grinding wheel will not collide with the limit clamp 21;

[0036] Step 2. After the height adjustment of the limit clamp 21 is completed, start the servo motor 3 to drive the bidirectional threaded shaft 4 to rotate, and drive the two moving plates 7 to move toward each other through the moving block 6. The two moving plates 7 move toward each other through the mounting plate 14, the limit plate 17, the square column 18 and the connecting rod 20, so that the workpiece is firmly fixed. At this time, the workpiece is leveled by the leveling device body 23.
