Abstract

The present invention discloses an assembled laser cutting machine body structure, which belongs to the technical field of laser cutting equipment, and includes a plurality of assembly beds, wherein adjacent assembly beds are connected by connecting parts, and fixed frames are provided on both sides of the assembly beds, and a first linear module is provided on the top of the fixed frames.

The assembly position of the abutment column on the top of the assembly bed is adjusted as needed, and multi-point contact matching is conveniently performed according to the bottom surface shape of the cutting component, so that the cutting component still has the abutment column on the bottom side of the weld after cutting for abutment support, thereby improving the assembly stability.

Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting equipment, and in particular relates to an assembled laser cutting fuselage structure. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize or reach its ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece. In the existing technology, due to the strong adaptability of laser cutting, there are laser cutting equipment used to cut large components.

[0003] The Chinese invention patent with authorization announcement number CN118543989A discloses a split laser cutting machine body structure, which relates to the field of laser cutting technology, including a main bed and an auxiliary bed. The main bed includes side wall panels and end bed panels arranged at the ends of the side wall panels. The side wall panels are provided with a first slide rail for facilitating the sliding of the laser cutting head; the auxiliary bed includes an accordion cover panel and a second slide rail arranged on the accordion cover panel. The second slide rail is connected to the first slide rail, and the accordion cover panel is connected to the end bed panel. The present invention has a simple structure, with the main body structure and the auxiliary body structure designed as a split type. The main bed adopts a semi-hollow structure to avoid the influence on the strength of the bed during processing, installation and transportation, while ensuring that the bed has high strength and rigidity. The auxiliary body structure is detachable and can effectively lengthen the sliding stroke of the accordion structure while meeting the effective cutting stroke of large-format lengths. However, in actual use, when large components are laser cut, the weld seam has a large position difference at the front and end of the cutting stroke. Traditional edge-type clamps can easily cause the component to collapse into the weld gap at the rear end or after cutting is completed, resulting in collision between the two sides of the weld gap and wear. There is room for improvement. Summary of the Invention

[0045] The clamp body 11 is a corresponding U-shaped clamp, which is assembled at the edge of the component to be processed. The clamp clamps the edge of the component to be processed to improve the support stability.

[0046] See also Figure 3-Figure 5 The coupling mechanism 3 includes a ferrule 301, a plurality of slots are provided on the outer peripheral side of the ferrule 301, and a clamping plate 302 is slidably connected in the slot, and the clamping plate 302 moves in the slot to abut against the inner side of the assembly hole for limiting position;

[0047] A wedge 304 is connected to the side of the clamping plate 302 close to the abutment column 2. The cross-section of the wedge 304 is triangular, and the inclined surface of the wedge 304 is close to the side of the abutment column 2. A sliding hole is opened at the top of the inner cavity of the card slot, and a brake rod 308 is slidably connected in the sliding hole. The bottom end of the brake rod 308 contacts the inclined surface of the wedge 304, and a second spring 309 is sleeved on the outside of the brake rod 308. The two ends of the second spring 309 are respectively connected to the outer top of the brake rod 308 and the top of the card sleeve 301;

[0048] The top of the ferrule 301 is connected to a threaded barrel 311, and the outer thread of the threaded barrel 311 is connected to a threaded seat, and the top of the threaded column is connected to a knob 310. The knob 310 drives the threaded seat to rotate outside the threaded barrel 311, and the bottom side of the knob 310 moves to squeeze the brake rod 308 to drive the wedge block 304;

[0049] The cross section of the clamping plate 302 is U-shaped, and a plurality of limiting engaging teeth 303 are connected to the inner side of the clamping plate 302 along the height direction, and corresponding limiting engaging teeth 303 are connected to corresponding positions on the inner side of the assembly hole of the assembly bed 1 .

[0050] The outer sides of the ferrule 301 are connected with seals 312, and the seals 312 fit on both sides of the assembly hole, which is conducive to improving the sealing performance of the assembly;

[0051] When the cam 310 is in the unlock state, the second spring 309 is pressed against the locking cam 308, and the locking cam 308 is in the unlock state, so that the locking cam 308 is locked.

[0052] The support and abutment at multiple points can prevent the cutting accuracy from being affected by the collapse of the rear side of the component due to lack of support after the cutting stroke on the front side is completed.

[0053] In order to improve the movement stability of the wedge block 304 and avoid fitting deviation, guide rods 305 are connected to the four sides of the inner side of the wedge block 304, and a guide sleeve 306 is slidably connected to the outside of the guide rod 305. The guide sleeve 306 is connected to the corresponding position on one side of the inner cavity of the card slot, and a first spring 307 is provided on the outside of the guide rod 305. The two ends of the first spring 307 are respectively connected to the corresponding positions of the guide sleeve 306 and one side of the splint 302.

[0054] Specifically: through the designed guide rod 305, the sliding of the wedge block 304 in the guide sleeve 306 through the guide rod 305 is more stable. When the wedge block 304 moves, it can squeeze the external first spring 307. The first spring 307 can use its own elastic force to drive the wedge block 304 to reset, which makes it convenient for the wedge block 304 to drive the splint 302 to reset after the reverse rotation.

[0055] A penetration groove is provided on one side of the outer portion of the ferrule 301, and the penetration groove is located at the bottom of the ferrule. The inner cavity of the penetration groove is slidably connected to the limit tooth block 313. A limit tooth groove 320 is provided on the outer side of the abutment column 2 at a position corresponding to the limit tooth block 313. The engagement between the limit tooth block 313 and the limit tooth groove 320 adjusts the limit height of the abutment column 2.

[0056] Both sides of the limiting tooth block 313 are connected to a first telescopic rod 314 through a block body. The other end of the first telescopic rod 314 is connected to the slot body provided in the inner cavity of the slot. A third spring 315 is sleeved on the outer wall of the first telescopic rod 314. The third spring 315 is respectively connected to corresponding positions on one side of the block body and the slot body. A handle is connected to one side of the limiting tooth block 313.

[0057] Specifically: when the height of the abutment column 2 needs to be adjusted, the limit tooth block 313 can be driven to move in the penetration groove by pulling the handle, and the limit tooth block 313 can be separated from the limit tooth groove 320 on the outside of the abutment column 2. At this time, the abutment column 2 is in an unlocked state, and the staff can press the abutment column 2 according to the height of the equipment to match the abutment height relative to the position, so that the relative heights of multiple abutment columns 2 can be adjusted to match the abutment support of the abutment surfaces of components with different depths, thereby improving the abutment adaptability.

[0058] The first telescopic rod 314 is designed to absorb the vibration of the limiting tooth block 313 through the third spring 315 outside the first telescopic rod 314, thereby facilitating the full engagement of the limiting tooth block 313 with the limiting tooth groove 320.

[0059] The bottom of the ferrule 301 is connected to a supporting seat 318, the top of the supporting seat 318 is connected to a second telescopic rod 316, the top of the second telescopic rod 316 is connected to a chassis, the outer surface of the second telescopic rod 316 is provided with a fourth spring 317, the two ends of the fourth spring 317 correspond to the chassis and one side of the supporting seat 318 respectively, the chassis is slidably connected to the inner side of the ferrule 301, both sides of the supporting seat 318 are connected to ear seats, the top of the ear seat is connected to a connecting rod 319, and the other end of the connecting rod 319 is connected to the bottom of the ferrule 301;

[0060] Specifically: through the designed supporting seat 318, when the abutment column 2 is out of the limit, the abutment column 2 can be pressed and contacted with the bottom chassis, and the chassis can be forced to squeeze the second telescopic rod 316. The second telescopic rod 316 can pull the external fourth spring 317 when being squeezed, and the fourth spring 317 can use its own elastic force to absorb the impact of the abutment column 2, thereby improving the safety and stability of the placement of the top component, and when the limiting tooth block 313 is separated from the limiting tooth groove 320 again, the fourth spring 317 can use its own elastic force to drive the second telescopic rod 316 and the chassis to drive the top abutment column 2 to reset, thereby facilitating the calibration of the height of the abutment column 2.

[0061] See also Figure 5-Figure 6 The abutment mechanism 4 includes an abutment block 401, and a universal ball 403 is connected to the bottom of the abutment block 401. The universal ball 403 is rotatably connected to the ball groove opened at the top of the abutment column 2. A plurality of buffer springs 402 are equidistantly connected to the bottom of the abutment block 401 along the axis, and the other end of the buffer spring 402 is connected to the top of the abutment column 2.

[0062] Specifically: through the designed abutment mechanism 4, the abutment block 401 can contact the bottom side of the component at the corresponding position, and when the abutment block 401 contacts the special-shaped surface of the component, the universal ball 403 can be rotated in the ball groove to adjust the fitting angle, which is beneficial to improve the abutment support effect and reduce the abnormal movement of the cut position of the component.

[0064] The side of the fixing frame 5 is connected with a supporting block 10, which is connected to the assembly hole on the edge of the assembly bed 1 through the supporting block 10;

[0065] Specifically: Through the designed connecting component 6, when the assembly bed 1 is expanded, the fixed frames 5 on both sides can be quickly expanded and assembled through the connecting sleeves 604 on both sides and the limiting screws 605, and after the fixed frames 5 are assembled, the connecting frames 601 on both sides can be connected and assembled through the sliding rails of the first linear modules 7 on both sides. When the sliding rails are connected to the connecting frames 601, the positioning holes on one side of the sliding rails can be positioned and connected with the adjacent positioning pins 603, which is conducive to maintaining the assembly stability through the connecting frames 601 on both sides, so as to improve the movement of the second linear module 8 outside the first linear module 7 through the bottom movable seat.
