Description

Technical Field

[0001] This invention relates to a milling cutter and a device for removing laser cutting residue from a workpiece placement plate, belonging to the field of industrial machinery. Background Technology

[0002] Currently, there is no readily available equipment in China for removing laser cutting residue from workpiece placement plates in large-scale laser cutting equipment. Removal is still done manually by striking the plates with a hammer. This method is not only labor-intensive but also extremely inefficient and has a very low removal rate. When residue is not completely removed, the workpiece will lift up, significantly increasing the surface defects of the cut workpiece. Furthermore, when residue is knocked off, it may carry away some material from the workpiece placement plate, reducing its lifespan. Therefore, to improve the efficiency and accuracy of laser cutting residue removal and prevent a reduction in the lifespan of the workpiece placement plate, it is essential to develop an automated device for removing the workpiece placement plate. Summary of the Invention

[0003] This invention provides a milling cutter to solve the structural and installation problems of milling cutters capable of multi-directional and different spacing milling; it also provides a device for removing laser cutting residue from a workpiece placement plate. By using the milling cutter of this invention in conjunction with the workpiece support frame and the three-axis moving part, a platform for removing laser cutting residue from the workpiece placement plate is constructed.

This in turn drives the cutter shaft I57 and cutter shaft II61, which are mounted on the gear bearing seat integrated with the incomplete spur gear in the horizontal direction, to revolve around the mounting axis of the incomplete spur gear, thereby adjusting the distance between the milling cutter II78 and the milling cutter I79. The worm 76 is fastened to lock the distance between the milling cutter II78 and the milling cutter I79.

[0006] The power of motor IV52 is transmitted to the driving gear 64 and the transmission bevel gear 89 on the motor shaft 55 respectively.

Detailed Implementation

[0030] The invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of the invention is not limited to the description.

[0031] Example 1: As Figure 1-14As shown, a milling tool is driven by a worm gear 76 to adjust the distance between two parallel milling cutters II78 and I79; it is also driven by a motor IV52 to rotate milling cutters II78 and I79, and simultaneously to enable a face milling cutter 87 perpendicular to milling cutter II78 to perform rotary milling motion.

[0032] Furthermore, the rotation of the worm 76 can be controlled by a fastening screw. The rotation of the worm 76 sequentially drives the turbine 75, the turbine shaft drive gear 74, and the auxiliary shaft gear 73, and transmits power to the incomplete spur gears in the lower gear 70 of shaft II and the lower gear 69 of shaft I. This, in turn, drives the cutter shafts I57 and II61, which are mounted on a gear bearing seat integrated with the incomplete spur gear in the horizontal direction, to revolve around the mounting axis of the incomplete spur gear, thereby adjusting the spacing between the milling cutter II78 and the milling cutter I79. The worm 76 is fastened to lock the spacing between the milling cutter II78 and the milling cutter I79.

[0033] The power of motor IV52 is transmitted to the driving gear 64 and the transmission bevel gear 89 on the motor shaft 55 respectively. The movement of the transmission bevel gear 89 drives the driven bevel gear 90 to rotate. The driven bevel gear 90 is fixedly connected to the end mill shaft I91, and the end mill shaft I91 is connected to the end mill 87, so that the end mill 87 can perform rotary milling motion.

[0034] The driving gear 64 transmits power to the gear 68 on the rotating shaft I through the driven gear I 65 and the driven gear II 66. A bearing is installed between the gear 68 on the rotating shaft I and the rotating shaft I 59, so that the moving shaft of the gear 68 on the rotating shaft I remains stationary. The gear 68 on the rotating shaft I meshes with the cutter shaft I gear 67 and the gear 72 on the rotating shaft II respectively. A bearing is also installed between the gear 72 on the rotating shaft II and the rotating shaft II 60, so that the moving shaft of the gear 72 on the rotating shaft II remains stationary. The gear 72 on the rotating shaft II meshes with the cutter shaft II gear 71, thereby transmitting force to the cutter shaft I gear 67 and the cutter shaft II gear 71, driving the milling cutter I 79, which is coaxially mounted with the cutter shaft I gear 67, and the milling cutter II 78, which is coaxially mounted with the cutter shaft II gear 71, to rotate.

[0035] By designing the auxiliary shaft gear 73, interference between the worm gear 75 and the gear 72 on shaft II can be avoided. Simultaneously, a larger gear size can be used for gear 72 on shaft II, which increases the transmission ratio, thus allowing the milling cutter to achieve a higher rotational speed. A bearing is installed between gear 68 on shaft I and shaft I 59. This allows gear 68 on shaft I to rotate, causing the outer ring of the bearing to rotate while the shaft remains stationary. When gear 69 on shaft I rotates, it causes shaft I 59 to rotate, causing the inner ring of the bearing to rotate while gear 68 on shaft I remains stationary. Furthermore, the worm gear 76 is fixed in place by screws on the bearing housing. This fixes gear 69 on shaft I and gear 70 on shaft II, locking the distance between milling cutters II 78 and I 79 without interfering with their rotation.

[0036] Furthermore, the milling cutter 3 can be configured to include a motor IV52, an upper housing cover 53, a lower housing 54, a motor shaft 55, a motor driven shaft I 56, a cutter shaft I 57, a motor driven shaft II 58, a rotating shaft I 59, a rotating shaft II 60, a cutter shaft II 61, a transmission auxiliary shaft 62, a worm gear 63, a driving gear 64, a driven gear I 65, a driven gear II 66, a cutter shaft I gear 67, a rotating shaft I upper gear 68, a rotating shaft I lower gear 69, a rotating shaft II lower gear 70, a cutter shaft II gear 71, a rotating shaft II upper gear 72, an auxiliary shaft gear 73, a worm gear shaft transmission gear 74, a worm 75, a worm gear 76, and a rotating handle 7. 7.

The other end of the worm 76 is fitted with a bearing. After assembly, it meshes with the turbine 75. The rotating handle 77 is directly fitted into the through hole of the worm gear 76 and fixed with screws. The motor shaft bearing housing 80, motor driven bearing housing I81, motor driven bearing housing II82, cutter shaft bearing housing I83, cutter shaft bearing housing II84, auxiliary shaft bearing housing 85, and turbine shaft bearing housing 86 are all installed on the upper cover 53 with screws and nuts. These bearing housings will cooperate with the shoulders of each shaft to prevent axial movement of the shaft. Taking the motor shaft bearing housing 80 as an example: the upper end of the motor shaft 55 is a stepped shaft, which forms a shoulder that cooperates with the bearing in the bearing housing, thereby fixing the shaft axially.

During assembly, the short shaft is first installed with the bearing in the bearing mounting block 28 for coaxiality. Then, one end of the short shaft is connected to the helical gear II33 by a pin, and the other end of the short shaft is connected to the coupling I25. The shaft assembly II27 is connected to the other end of the drive shaft 26; the upper guide rail 35 and lower guide rail 39 of the crossbeam square tube 14 are assembled in the same way as the parallel beam guide rail I20, the crossbeam helical rack 36 of the crossbeam square tube 14 are assembled in the same way as the parallel beam helical rack I22, and the upper guide rail slider 37, lower guide rail slider 38 and parallel beam slider 29 of the crossbeam square tube 14 are assembled in the same way; the upper plate on one side of the vertical beam mounting plate 15 is connected and fixed to the upper guide rail slider 37 of the crossbeam, and the lower plate on one side of the vertical beam mounting plate 15 is connected and fixed to the lower guide rail slider 38 of the crossbeam.

The output shaft of motor III43 and helical gear 49 are fixed with pins. Helical gear 49 meshes with the crossbeam helical rack 36. When motor III43 rotates, it drives the vertical beam mounting plate 15 to move laterally along the upper guide rail 35 and the lower guide rail 39 of the crossbeam. Motor II41 is mounted on one side of the vertical beam mounting plate 15 with screws. The output shaft of motor II41 extends from the other side of the vertical beam mounting plate 15 and is fitted with a helical gear 50, which is also fixed with pins.

The longitudinal axis sliders I44 and II45 are fixed to the baffle 42 with screws. When the vertical beam mounting plate 15 moves laterally, it drives the vertical beam square tube 16 to move laterally. When the motor II41 rotates, the motor II helical gear 50 drives the vertical beam helical rack 51 to move up and down, thereby driving the vertical beam square tube 16 to move up and down. The bottom of the vertical beam square tube 16 is welded with a box mounting plate 48. The milling cutter 3 is mounted on the box mounting plate 48. The motor IV52 in the milling cutter 3 is directly mounted with screws. The upper box cover 53 in the milling cutter 3 is mounted to the box mounting plate 48 with screws and nuts.

[0043] In this invention, the movement in three degrees of freedom, via guide rails and a helical rack, allows for smoother operation of the entire mechanism. The two sets of guide rails, arranged laterally and longitudinally, ensure more even force distribution and increase the mechanism's reliability, thereby enabling more precise milling cutter operation. Furthermore, the vertical baffle 42 provides both protection and a mounting position for the slider.

[0044] The working principle of this invention is as follows:

[0045] Before machining, adjust the horizontal distance between the two vertical tools to meet machining requirements. First, loosen the fastening screws on the bearing housing of the worm 76. Then, rotate the handle 77 to rotate the worm 76. Through the transmission of intermediate gears such as the worm 76, turbine 75, turbine shaft drive gear 74, and auxiliary shaft gear 73, the power is finally transmitted to the lower gear 69 of shaft I and the lower gear 70 of shaft II. The rotation of the lower gear 69 of shaft I and the lower gear 70 of shaft II will drive the tool shafts I57 and II61 mounted on the gear bearing housing to move, thereby adjusting the horizontal distance between the tools. The ideal distance is the initial width of the horizontal bar on the workpiece placement plate 5. After adjustment, tighten the fastening screws to secure the worm 76 and achieve self-locking.

[0046] At the start of milling, the milling cutters 3, including milling cutter I79, milling cutter II78, and end mill 87, are adjusted to suitable machining positions on the workpiece placement plate 5 by the movement of the three-axis moving part 2 in the longitudinal, transverse, and vertical directions. The power of motor IV52 is transmitted to the driving gear 64 and the drive bevel gear 89 on the motor shaft 55. The drive bevel gear 89 and the driven bevel gear 90 mesh. When the drive bevel gear 89 moves, it drives the driven bevel gear 90 to rotate. Because the driven bevel gear 90 is fixedly connected to the end mill shaft I91, and the end mill shaft I91 is connected to the end mill 87, motor IV52 ultimately drives the end mill 87 to perform rotary milling motion.

[0047] The driving gear 64 transmits power to the gear 68 on shaft I through the meshing of two intermediate gears, driven gear I 65 and driven gear II 66. A bearing is installed between gear 68 on shaft I and shaft I 59. Gear 68 is connected to the outer ring of the bearing, and shaft I 59 is connected to the inner ring of the bearing. Therefore, when gear 68 on shaft I rotates, it drives the outer ring of the bearing to rotate while the shaft remains stationary. When gear 69 on shaft I rotates, it drives shaft I 59 to rotate, causing the inner ring of the bearing to rotate while gear 68 on shaft I remains stationary. Gear 68 on shaft I meshes with gear 67 on cutter shaft I and gear 72 on shaft II. Gear 72 on shaft II, like gear 68 on shaft I, moves the gears while the shaft remains stationary. Gear 72 on shaft II also meshes with gear 71 on cutter shaft II. Therefore, through this series of gear transmissions, the power of motor IV 52 is ultimately transmitted to gear 67 on cutter shaft I and gear 71 on cutter shaft II. The rotation directions of gears 67 and 71 on cutter shaft I and II are opposite. Gears 67 and 71 are connected to cutter shafts I57 and II61 via a key, causing the gears to drive the shafts to rotate together. After transmission through each gear, the rotation directions of cutter shafts I57 and II61 are opposite, resulting in the opposite rotation directions of milling cutters II78 and I79 during milling. Because milling cutters II78 and I79 rotate in opposite directions while their cutting edges rotate in the same direction, they generate opposing forces of equal magnitude and opposite direction in the vertical direction during milling. This achieves torque balance in the vertical direction of the milling position, preventing the crossbars of the workpiece placement plate from bulging or dipping and thus affecting subsequent end-face milling.

[0048] The laser cutting residue on the workpiece placement plate has low hardness and plasticity, so low-speed milling is selected. Experimental results show that milling effect is better when the milling cutter speed is 150-200 r / min, which can basically remove the residue without affecting the normal use of the workpiece placement plate.

[0049] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
