Technical Field

The invention relates to a milling cutter and a device for removing laser cutting residues on a workpiece placing plate, belonging to the field of industrial machines.

Background

The existing domestic large-scale laser cutting equipment does not have ready-made equipment for removing the laser cutting residues on the workpiece placing plate at present, and the laser cutting residues are removed in a mode of manually holding an iron hammer for knocking. This removal is not only labor intensive, but also extremely inefficient and inefficient. When the residue is not completely removed, the workpiece is placed on the cutter to be tilted, so that the surface error of the cut workpiece is greatly increased. And when the residue falls off by means of knocking, a part of the material on the workpiece placing plate may be taken away, which reduces the service life of the workpiece placing plate. Therefore, in order to improve the efficiency and accuracy of removing the laser cutting residue and to prevent the life of the workpiece placing plate from being reduced, it is necessary to develop an apparatus that can automatically remove the workpiece placing plate.

The working principle of the invention is as follows:

the horizontal distance between the two vertical cutters is adjusted before machining so as to meet the machining requirement. Firstly, a fastening screw on a bearing seat of a worm 76 is unscrewed, then the worm 76 is driven to rotate by rotating a rotating handle 77, power is finally transmitted to a lower gear 69 of a rotating shaft I and a lower gear 70 of a rotating shaft II through transmission of intermediate gears such as the worm 76, a turbine 75, a turbine shaft transmission gear 74, an auxiliary shaft gear 73 and the like, and the rotation of the lower gear 69 of the rotating shaft I and the lower gear 70 of the rotating shaft II drives a cutter shaft I57 and a cutter shaft II61 which are arranged on a gear bearing seat to move, so that the adjustment of the horizontal distance of the cutters is realized, and the adjusted ideal distance is the initial width of a cross bar on a workpiece placing plate 5. After adjustment, the worm 76 is fastened by screwing the fastening screw, so that self-locking is realized.

At the start of milling, the mills I79, II78, and end mills 87 of the milling cutter box 3 are adjusted to the processing proper positions on the workpiece placement plate 5 by the movement of the three-coordinate moving device 2 in the longitudinal, lateral, and vertical directions. The power of the motor IV52 is transmitted to the drive gear 64 and the drive bevel gear 89 on the shaft through the motor shaft 55. The drive bevel gear 89 is meshed with the driven bevel gear 90, when the drive bevel gear 89 moves, the driven bevel gear 90 is driven to rotate, and because the driven bevel gear 90 is fixedly connected with the end face milling cutter shaft I91, and the end face milling cutter shaft I91 is connected with the end face milling cutter 87, finally the motor IV52 drives the end face milling cutter 87 to do rotary milling movement.

The driving gear 64 transmits power to the gear 68 on the rotating shaft I through the meshing transmission of two intermediate gears, namely the driven gear I65 and the driven gear II 66. A bearing is arranged between the upper gear 68 of the rotating shaft I and the rotating shaft I59, the upper gear 68 of the rotating shaft I is connected with the outer ring of the bearing, and the rotating shaft I59 is connected with the inner ring of the bearing, so that when the upper gear 68 of the rotating shaft I rotates, the outer ring of the bearing is driven to rotate but the shaft does not move, and when the lower gear 69 of the rotating shaft I rotates, the lower gear of the rotating shaft I drives the rotating shaft I59 to rotate, the inner ring of the bearing rotates, and the upper gear 68 of the rotating shaft I does not move. The upper gear 68 of the rotating shaft I is meshed with the gear 67 of the cutter shaft I and the upper gear 72 of the rotating shaft II respectively, the gear 72 of the rotating shaft II is also fixed with the gear moving shaft as the upper gear 68 of the rotating shaft I, and the upper gear 72 of the rotating shaft II is meshed with the gear 71 of the cutter shaft II, so that the power of the motor IV52 is finally transmitted to the gear 67 of the cutter shaft I and the gear 71 of the cutter shaft II through the series of gear transmission. The rotation directions of the cutter shaft I gear 67 and the cutter shaft II gear 71 are opposite, the cutter shaft I gear 67 and the cutter shaft II gear 71 are connected with the cutter shaft I57 and the cutter shaft II61 through flat keys, so that the gears can drive the shafts to rotate together, and the rotation directions of the cutter shaft I57 and the cutter shaft II61 are opposite after the gears are driven, so that the rotation directions of the milling cutter II78 and the milling cutter I79 are opposite. Because the rotation directions of the cutting edges on the milling cutters II78 and I79 are opposite, opposite forces with opposite directions and the same magnitude can be generated in the vertical direction during milling, so that moment balance is achieved in the vertical direction of the milling position, and the transverse strips of the workpiece placing plate are not protruded or recessed upwards so as not to influence the subsequent end face milling.

The hardness and plasticity of the laser cutting residue on the workpiece placing plate are low, so that low-speed milling is selected. The experimental result shows that the milling effect is better when the rotating speed of the milling cutter is 150-200r/min, and the residues can be basically removed without influencing the normal use of the workpiece placing plate.
