Description

Technical Field

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

[0002] Laser cutting utilizes a highly focused high-power density laser beam to irradiate a workpiece, causing the irradiated material to rapidly melt, vaporize, or reach the ignition point. At the same time, molten material is blown away by a high-speed air flow coaxial with the beam, thereby realizing cutting the workpiece. In the prior art, due to the strong adaptability of laser cutting, there are laser cutting devices used for cutting large components.

[0003] The Chinese invention patent with the authorization announcement number CN118543989A discloses a split-type laser cutting machine body structure, which relates to the technical field of laser cutting. It includes a main bed body and an auxiliary bed body. The main bed body includes side wall panels and end bed plates arranged at the ends of the side wall panels. The side wall panels are provided with first slide rails for facilitating the sliding of the laser cutting head; the auxiliary bed body includes bellows cover plates and second slide rails arranged on the bellows cover plates. The second slide rails are connected to the first slide rails, and the bellows cover plates are connected to the end bed plates. The structure of the present invention is simple. The main body structure and the auxiliary structure of the machine body are designed in a split manner. The main bed body adopts a semi-hollow structure, avoiding the influence on the strength of the bed body during processing, installation, and transportation, while ensuring that the bed body has high strength and rigidity. The auxiliary structure is detachably arranged, effectively lengthening the sliding stroke of the bellows structure while meeting the effective cutting stroke of the large-format length. However, in actual use, when large components are laser cut, there is a large difference in position between the welding and cutting seams at the front and end of the cutting stroke. Traditional edge-type jigs are prone to causing the collapse of the component towards the welding and cutting gap at the rear end or after cutting, resulting in mutual collision and wear on both sides of the welding and cutting seams, and there is room for improvement. Summary of the Invention

[0010] As a further description of the above technical solution: Guide rods are connected to the four surrounding positions on the inner side of the wedge block. Guide sleeves are slidably connected to the outside of the guide rods. The guide sleeves are connected to the corresponding positions on one side of the inner cavity of the clamping groove. A first spring is sleeved outside the guide rods, and two ends of the first spring are respectively connected to the guide sleeve and the corresponding position on one side of the clamping plate.

[0011] As a further description of the above technical solution: A through groove is formed on one side of the outside of the ferrule, and the through groove is located at the bottom of the clamping groove. A limiting tooth block is slidably connected in the inner cavity of the through groove. A limiting tooth groove is formed at the position corresponding to the limiting tooth block on the outside of the abutting column. The meshing of the limiting tooth block and the limiting tooth groove adjusts the limiting height of the abutting column.

[0012] As a further description of the above technical solution: Both sides of the limit tooth block are connected with a first telescopic rod through a block body. The other end of the first telescopic rod is connected to a groove body opened in the inner cavity of the through groove. A third spring is sleeved on the outer side wall of the first telescopic rod. The third spring is respectively connected to the corresponding positions on one side of the block body and the groove body.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: 1. In the present invention, through the designed coupling mechanism, by driving the knob to drive the threaded seat to rotate outside the threaded barrel, at this time, the threaded seat can move downward through thread cooperation and squeeze the brake rod. When the brake rod is squeezed, the second spring can be compressed under force. When the brake rod moves downward, the end can squeeze the bottom wedge block. When the wedge block is squeezed, it can drive the clamping plate to move radially outward. The movement of the clamping plate can drive the limit meshing teeth to mesh with the limit meshing teeth in the assembly hole. Through the meshing assembly of the circumferential clamping plate and the assembly hole and the axial movement of the limit bushing, the rapid assembly coupling of the butting column can be realized. The assembly position of the butting column on the top of the assembly bed body can be adjusted as needed, which is convenient for multi-point contact matching according to the bottom shape of the cutting member, so that there is still a butting column at the bottom side of the weld after the cutting member is cut for butting support, improving the assembly stability; 2. In the present invention, when it is necessary to adjust the height of the abutting column, the handle is pulled to drive the limiting tooth block to move in the through slot. The movement of the limiting tooth block can separate from the limiting tooth groove on the outer side of the abutting column. At this time, the abutting column is in an unlocked state, and the staff can press the abutting column according to the height of the equipment to make it match the abutting height of the relative position. By adjusting the relative heights of multiple abutting columns, the abutting support of the abutting surfaces of components with different depths can be matched, improving the abutting adaptability. 3. In the present invention, through the designed connection assembly, when expanding the assembled bed body, the two fixed frames can be quickly assembled and expanded through the connection sleeves and limiting screws on both sides. And after the fixed frames are assembled, the two connecting frames can be connected and assembled through the slide rails of the two first linear modules. When the slide rail is connected to the connecting frame, the positioning holes on one side of the slide rail can be positioned and connected with the adjacent positioning pins, which is beneficial to maintaining the assembly stability through the two connecting frames to improve the movement of the second linear module through the bottom moving seat outside the first linear module.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-8 , the present invention provides a technical solution: an assembled laser cutting machine body structure, including a plurality of assembly bed bodies 1, and adjacent assembly bed bodies 1 are connected by a connector 12. Fixed frames 5 are provided on both sides of the assembly bed body 1. A first linear module 7 is provided on the top of the fixed frame 5, and adjacent first linear modules 7 are coupled by a connection component 6. A second linear module 8 is slidably connected between the two first linear modules 7 through a moving part, and a laser cutting machine main body 9 is slidably connected to the top of the second linear module 8 through a moving part; A plurality of detachable contact posts 2 are provided on the top of the assembly bed body 1. The contact post 2 abuts against the edge of the cutting gap of the to-be-welded and cut component. A coupling mechanism 3 is provided at the bottom of the contact post 2. The coupling mechanism 3 is connected to the assembly holes arrayed on the top of the assembly bed body 1. A contact mechanism 4 and a fixture main body 11 are respectively installed on the tops of the plurality of contact posts 2.

[0020] Among them, the fixture main body 11 is a corresponding U-shaped fixture, which is assembled at the edge position of the to-be-processed component. The edge of the to-be-processed component is clamped by the fixture to improve the support stability.

[0021] Please refer to Figures 3-5, the coupling mechanism 3 includes a ferrule 301. A plurality of clamping grooves are formed on the outer peripheral side of the ferrule 301, and clamping plates 302 are slidably connected in the clamping grooves. The clamping plates 302 are in abutting and limiting contact with the inner side of the assembly hole through the movement in the clamping grooves; One side of the clamping plate 302 close to the abutting column 2 is connected with a wedge block 304. The cross-sectional shape of the wedge block 304 is triangular, and the inclined surface side of the wedge block 304 is close to one side of the abutting column 2. A sliding hole is formed at the top of the inner cavity of the clamping groove. A brake rod 308 is slidably connected in the sliding hole, and the bottom end of the brake rod 308 is in contact with the inclined surface of the wedge block 304. A second spring 309 is sleeved outside the brake rod 308, and both ends of the second spring 309 are respectively connected with the outer part of the top end of the brake rod 308 and the top of the ferrule 301; The top of the ferrule 301 is connected with a threaded cylinder 311. A threaded seat is externally threaded to the threaded cylinder 311, and a knob 310 is connected to the top of the threaded column. By driving the knob 310, the threaded seat rotates and moves outside the threaded cylinder 311, and the bottom side of the knob 310 moves to squeeze the brake rod 308 to drive the wedge block 304; The cross-sectional shape of the clamping plate 302 is U-shaped, and a plurality of limiting meshing teeth 303 are connected along the height direction on the inner side of the clamping plate 302, and corresponding limiting meshing teeth 303 are connected at the corresponding positions on the inner side of the assembly hole of the assembly bed body 1.

[0022] Sealing members 312 are connected to both sides of the outside of the ferrule 301, and the sealing members 312 are in fit with both sides of the assembly hole, which is beneficial to improving the assembly sealing performance; Specifically: through the designed coupling mechanism 3, the threaded seat can be driven to rotate outside the threaded cylinder 311 by driving the knob 310. At this time, the threaded seat can move downward through thread cooperation and squeeze the brake rod 308. The second spring 309 can be compressed under force when the brake rod 308 is squeezed. When the brake rod 308 moves downward, the end can squeeze the bottom wedge block 304. When the wedge block 304 is squeezed, the clamping plate 302 can be driven to move radially outward. The movement of the clamping plate 302 can drive the limiting meshing teeth 303 to mesh with the limiting meshing teeth 303 in the assembly hole. Thus, the axial movement of the ferrule 301 can be limited through the meshing assembly of the peripheral clamping plate 302 and the assembly hole, and the rapid assembly coupling of the abutting column 2 can be realized, which is beneficial to adjusting the assembly position of the abutting column 2 at the top of the assembly bed body 1 as needed, facilitating the multi-point contact matching according to the bottom shape of the cutting member, and improving the assembly stability; Through the multi-point supporting and abutting, it can be avoided that after the front cutting stroke of the member is completed, the collapse of the rear side of the member due to no support affects the cutting accuracy.

[0023] To improve the moving stability of the wedge block 304 and avoid fitting deviation, guide rods 305 are also connected to the periphery of the inner side of the wedge block 304. A guide sleeve 306 is slidably connected to the outside of the guide rod 305. The guide sleeve 306 is connected to a corresponding position on one side of the inner cavity of the card slot. A first spring 307 is sleeved outside the guide rod 305. The two ends of the first spring 307 are respectively connected to corresponding positions on one side of the guide sleeve 306 and the clamping plate 302.

[0024] Specifically: Through the designed guide rod 305, the wedge block 304 slides more stably in the guide sleeve 306 through the guide rod 305. When the wedge block 304 moves, it can squeeze the external first spring 307, and the first spring 307 can drive the wedge block 304 to reset by using its own elastic force, which is convenient for the wedge block 304 to drive the clamping plate 302 to reset after reverse selection and rotation.

[0025] A through slot is opened on one side of the outside of the bushing 301, and the through slot is located at the bottom of the card slot. A limit tooth block 313 is slidably connected to the inner cavity of the through slot. A limit tooth groove 320 is opened at the corresponding position of the outside of the abutting column 2 corresponding to the limit tooth block 313. The engagement of the limit tooth block 313 and the limit tooth groove 320 adjusts the limit height of the abutting column 2; Both sides of the limit tooth block 313 are connected with a first telescopic rod 314 through a block. The other end of the first telescopic rod 314 is connected to a groove body opened in the inner cavity of the through slot. A third spring 315 is sleeved on the outer side wall of the first telescopic rod 314. The third spring 315 is respectively connected to corresponding positions on one side of the block and the groove body. A handle is connected to one side of the limit tooth block 313; Specifically: When it is necessary to adjust the height of the abutting column 2, the limit tooth block 313 can be driven to move in the through slot by pulling the handle. The movement of the limit tooth block 313 can be separated from the limit tooth groove 320 on the outside of the abutting column 2. At this time, the abutting column 2 is in an unlocked state. The staff can press the abutting column 2 according to the height of the equipment to make it match the abutting height of the relative position, so that by adjusting the relative height of multiple abutting columns 2, the abutting support of the abutting surface of components with different depths can be matched, and the abutting adaptability can be improved.

[0026] Through the designed first telescopic rod 314, the vibration of the limit tooth block 313 can be absorbed by the third spring 315 outside the first telescopic rod 314, which is convenient to keep the full engagement of the limit tooth block 313 and the limit tooth groove 320; A supporting seat 318 is connected to the bottom of the bushing 301. A second telescopic rod 316 is connected to the top of the supporting seat 318. The top of the second telescopic rod 316 is connected to a chassis. A fourth spring 317 is sleeved outside the second telescopic rod 316. The two ends of the fourth spring 317 are respectively connected to corresponding positions on one side of the chassis and the supporting seat 318. The chassis is slidably connected to the inside of the bushing 301. Both sides of the supporting seat 318 are connected with ear seats. A connecting rod 319 is connected to the top of the ear seat. The other end of the connecting rod 319 is connected to the bottom of the bushing 301; Specifically: through the designed supporting seat 318, when the abutting column 2 is disengaged from the limit, the abutting column 2 can come into contact with the bottom chassis under pressure. When the chassis is stressed, it can squeeze the second telescopic rod 316. The second telescopic rod 316 can pull the external fourth spring 317 when being squeezed. The fourth spring 317 can use its own elastic force to absorb the impact of the abutting column 2, improving the safety and stability of the placement of the top member. And when the limiting tooth block 313 is separated from the limiting tooth groove 320 again, the fourth spring 317 can drive the second telescopic rod 316 and the chassis to drive the top abutting column 2 to reset by its own elastic force, thus facilitating the calibration of the height of the abutting column 2.

[0027] Please refer to Figures 5-6 , the abutting mechanism 4 includes an abutting block 401. A universal ball 403 is connected to the bottom of the abutting block 401. The universal ball 403 is rotatably connected to a ball groove opened at the top of the abutting column 2. A plurality of buffer springs 402 are connected to the bottom of the abutting block 401 at equal intervals along the axis, and the other ends of the buffer springs 402 are connected to the top of the abutting column 2.

[0028] Specifically: through the designed abutting mechanism 4, the abutting block 401 can come into contact with the bottom side of the component at the corresponding position, and when the abutting block 401 contacts the special-shaped surface of the component, it can adjust the fitting angle through the rotation of the universal ball 403 in the ball groove, which is beneficial to improving the abutting and supporting effect and reducing the movement of the cut position of the component.

[0029] Please refer to Figures 7-8 , the connecting component 6 includes a connecting frame 601 and a connecting sleeve 604. Positioning pins 603 are connected to both sides of the connecting frame 601. Corresponding positioning holes are opened on the track side of the first linear module 7. The tracks of the two adjacent first linear modules 7 on both sides are positioned through the positioning holes. Fixing rods 602 corresponding to the positions are opened on both sides of the connecting frame 601, and the fixing rods 602 are inserted into the slot holes opened at the corresponding positions. Limiting screws 605 are threadedly connected to both sides of the connecting sleeve 604, and the limiting screws 605 are threadedly connected to the nut seats arranged inside the fixing frame 5; A supporting block 10 is connected to the side of the fixing frame 5, and the supporting block 10 is connected to the edge of the assembly bed 1 through the assembly hole; Specifically: through the designed connecting component 6, when expanding the assembly bed 1, the two fixing frames 5 can be quickly expanded and assembled through the connecting sleeves 604 and the limiting screws 605 on both sides. And after the fixing frame 5 is assembled, the two connecting frames 601 can be connected and assembled through the slide rails of the two first linear modules 7. When the slide rail is connected to the connecting frame 601, the positioning hole on one side of the slide rail can be positioned and connected to the adjacent positioning pin 603, which is beneficial to maintaining the assembly stability through the two connecting frames 601 to improve the movement of the second linear module 8 through the bottom moving seat outside the first linear module 7.
