Description

Technical Field

[0001] This utility model relates to the field of laser cutting and milling technology, specifically to an integrated device for laser cutting and milling. Background Technology

[0002] Laser cutting uses an invisible beam of light instead of a traditional mechanical blade. It features high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save materials, smooth cuts, and low processing costs. It will gradually improve upon or replace traditional metal cutting equipment.

[0003] A laser cutting and milling integrated device is needed in the laser cutting process. Chinese utility model patent CN221910222U discloses such a device, which includes an operating table. A pull block is fixedly connected to the other side of the first clamping component. A locking rod is movably connected through the upper end of the pull block. A milling assembly is provided on the upper end of the operating table. This utility model separates the locking rod from the lower slot by pulling it. Pulling the pull block moves the first clamping component along the first and second support plates. Due to the presence of the first telescopic rod, the first clamping component simultaneously moves the second clamping component. Under the combined action of the first and second clamping components, the laser-cut part can be moved synchronously.

[0004] However, the switching between the grinding and milling cutters in the laser cutting and milling integrated device requires manually pulling the lever and pull block. This operation method is not convenient enough, which not only increases the labor intensity of the operator, but also easily leads to inaccurate positioning due to human factors, thereby affecting the processing accuracy and efficiency. Therefore, a laser cutting and milling integrated device is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 The laser cutting part grinding and milling integrated device in this embodiment includes an operating table 1, a grinding and milling mechanism 2 disposed on the top of the operating table 1, and a moving mechanism 18 disposed on the top of the operating table 1 for moving the grinding and milling mechanism 2. A switching mechanism for stable switching of the grinding and milling mechanism 2 is disposed on the top of the operating table 1, and a moving clamping mechanism is disposed on the top of the operating table 1.

[0026] The switching mechanism includes a mounting bracket 3 mounted on the top of the operating table 1. A drive motor 4 is fixedly mounted on the back of the mounting bracket 3. A transmission gear 5 is fixedly connected to the output shaft of the drive motor 4. A driven gear 6 that meshes with the transmission gear 5 is rotatably connected to the outside of the mounting bracket 3. A connecting rod 7 is hinged to the outside of the driven gear 6. A swing rod 8 is rotatably connected to the bottom end of the connecting rod 7. A transmission rod 9 is hinged to the bottom of the swing rod 8. A connecting plate 10 is fixedly connected to the bottom of the transmission rod 9.

[0027] Specifically, the middle part of the swing rod 8 is rotatably connected to the mounting frame 3 via a pin. There are two sets of transmission rods 9 and connecting plates 10, which are symmetrically distributed on the bottom of the swing rod 8. The mounting frame 3 has a movable hole that matches the transmission rod 9, and the transmission rod 9 is slidably connected inside the movable hole.

[0028] It should be noted that the milling mechanism 2 includes a milling cutter structure 21 and a grinding cutter structure 22. The milling cutter structure 21 includes a first servo motor fixedly connected to the bottom of the left connecting plate 10, and a milling cutter is fixedly connected to the output shaft of the first servo motor. The grinding cutter structure 22 includes a second servo motor fixedly connected to the bottom of the right connecting plate 10, and a grinding cutter is fixedly connected to the output shaft of the second servo motor. When it is necessary to switch between grinding and milling cutters, the controller starts the drive motor 4, whose output shaft drives the transmission gear 5 to rotate. The transmission gear 5 meshes with the driven gear 6. The rotation of the driven gear 6 will drive the connecting rod 7 to swing, which in turn will drive the swing rod 8 to swing around the pin shaft. The swing of the swing rod 8 will push the transmission rod 9 to slide in the moving hole inside the mounting bracket 3, thereby driving the connecting plate 10 to move up and down. The up and down movement of the connecting plate 10 realizes the position switching of the milling cutter and the grinding cutter in the vertical direction, thus completing the switching operation between grinding and milling cutters.

[0029] Please see Figure 1 and Figure 3 In this embodiment, the movable clamping mechanism includes a telescopic cylinder 11 fixedly installed outside the operating table 1. A placement seat 12 is fixedly connected to the output end of the telescopic cylinder 11, and a mounting seat 13 is fixedly connected to the top of the placement seat 12. An electric push rod 14 is fixedly installed inside the mounting seat 13, and a clamping plate 15 is fixedly connected to the output end of the electric push rod 14. The telescopic cylinder 11 is activated by the controller to extend or retract, and its output end pushes the placement seat 12 forward, moving the placement seat 12 to a suitable position for placing and processing the laser-cut parts.

[0030] The mounting base 13, the electric push rod 14, and the clamping plate 15 are all in two sets, with the two sets of clamping plates 15 symmetrically distributed on the top of the placement base 12. The laser-cut part is placed on the placement base 12, and then the electric push rod 14 is activated by the controller to extend and retract. Its output end pushes the clamping plate 15 towards the center. The two sets of clamping plates 15 cooperate to clamp and fix the laser-cut part, ensuring its stability during subsequent processing.

[0031] Specifically, a slide 16 is fixedly connected to the top of the operating table 1, and a limiting rod 17 extending into the slide 16 is fixedly connected to the bottom of the placement seat 12. The limiting rod 17 and the slide 16 are slidably connected.

[0032] Please see Figure 1 In this embodiment, the moving mechanism 18 includes four fixed seats 181 fixedly connected to the top of the operating table 1. A reduction motor 182 is fixedly mounted on the outside of the right fixed seat 181. A threaded rod 183 is fixedly connected to the output shaft of the reduction motor 182. A threaded sleeve 184 is threadedly connected to the outside of the threaded rod 183. A mounting plate 185 is fixedly connected to the outside of the threaded sleeve 184. The mounting frame 3 is fixedly mounted on the lower surface of the mounting plate 185 through the fixed plate. When it is necessary to perform milling processing on different positions of the laser-cut part, the reduction motor 182 is started by the controller. Its output shaft drives the threaded rod 183 to rotate. The threaded sleeve 184 is threadedly connected to the threaded rod 183. Under the rotation of the threaded rod 183, the threaded sleeve 184 moves linearly along the threaded rod 183. The mounting frame 3 is fixedly mounted on the lower surface of the mounting plate 185 through the fixed plate. Therefore, the mounting frame 3 will move with the movement of the threaded sleeve 184, thereby driving the milling mechanism 2 to move on the operating table 1 as a whole, realizing the processing of different positions of the laser-cut part.

[0033] A guide rod 187 is fixedly connected between the two fixed seats 181 on the left side, and a guide sleeve 186 is fixedly connected to the side of the mounting plate 185 away from the threaded sleeve 184. The guide sleeve 186 is slidably connected to the outside of the guide rod 187. By setting the guide sleeve 186 to slide on the guide rod 187, the guide rod 187 plays a guiding role, ensuring the stability of the movement of the mounting plate 185 and the milling mechanism 2.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the laser-cut workpiece is placed on the placement seat 12. The controller activates the extension and retraction of the electric push rod 14, whose output end pushes the clamping plate 15 to move towards the center. The two sets of symmetrically distributed clamping plates 15 cooperate with each other to clamp and fix the laser-cut workpiece. The controller activates the reduction motor 182 to drive the threaded rod 183 to rotate. The threaded sleeve 184 moves linearly on the threaded rod 183. The mounting plate 185 moves with the threaded sleeve 184. The guide sleeve 186 slides and guides on the guide rod 187, driving the mounting frame 3 and the milling mechanism 2 to move on the operating table 1. The drive motor 4 drives the transmission gear 5 to rotate. The transmission gear 5 drives the driven gear 6 to rotate. The connecting rod 7 swings with the driven gear 6, driving the swing rod 8 to swing around the pin shaft. The transmission rod 9 slides in the moving hole, pushing the two sets of connecting plates 10 to move up and down, realizing the switching between the milling cutter structure 21 and the grinding cutter structure 22. The first servo motor or the second servo motor drives the milling cutter or grinding cutter to rotate, performing milling or grinding processing on the laser-cut workpiece.
