Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, specifically referring to an adaptive laser positioning and cutting device for irregularly shaped steel structures. Background Technology

[0002] This invention relates to the field of irregular steel structure cutting and processing technology. In the laser cutting and processing of irregular steel structures such as H-beams and channel steel, the existing clamping and positioning devices are mostly fixed special fixtures. When changing the shape of steel for different cross-sectional dimensions, it is necessary to manually disassemble and replace the clamps and repeatedly adjust the clamping distance and positioning structure. The shape change operation is cumbersome and time-consuming, and it is difficult to adapt to the production needs of irregular steel in small batches of multiple specifications.

[0003] Most existing devices can only clamp and limit the steel profile from the outside, lacking an auxiliary positioning structure for the inner cavity of the steel profile. During the cutting process, the steel profile is prone to lateral displacement and movement, resulting in deviations in the cutting position, which directly affects the processing accuracy and cut quality of the finished product. To achieve multi-faceted circumferential cutting of the steel profile, it is usually necessary to configure an independent positioner or a multi-axis CNC linkage system. This not only increases the overall cost of the equipment, but also separates the clamping mechanism and the positioning mechanism, resulting in redundant equipment layout and occupying a large amount of factory space.

[0004] In addition, some adaptive clamping solutions have complex structures and numerous loading steps. Workers need to adjust multiple locking structures in sequence to complete the clamping, resulting in low loading efficiency and making it difficult to meet the needs of high-efficiency mass production in steel structure processing scenarios. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an adaptive laser positioning and cutting device for irregular steel structures, which effectively solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention provides an adaptive irregular steel structure laser positioning and cutting device, including a worktable, a conveyor belt, a laser cutting mechanism and a clamping frame. The conveyor belt is located on the top of the worktable, and a telescopic rod is provided at the bottom of the conveyor belt. The telescopic rod is electrically controlled. The laser cutting machine is slidably located on the top of the worktable. The clamping frame is located on the top of the worktable and on the side of the laser cutting machine. A driving mechanism is also provided on the worktable.

[0007] Furthermore, the worktable is provided with a driving mechanism, the driving mechanism includes a collar, the clamping frame is rotatably disposed inside the collar, the clamping frame includes a control ring and a clamping mechanism, and the clamping mechanism is symmetrically provided with positioning mechanisms.

[0008] Furthermore, the control ring includes a ring body with symmetrically arranged extension plates at both ends. A sliding groove three is symmetrically arranged inside the ring body, and a slider is slidably arranged in the sliding groove three. A drive wheel is provided on the opposite side of the slider and another slider. The drive wheel is an electric wheel. Limiting rods are symmetrically arranged on both sides of the slider. A passive tooth is provided on the circumferential sidewall of the ring body, and an annular groove is also opened on the circumferential sidewall of the ring body. The collar is fitted onto the annular groove.

[0009] Furthermore, the clamping mechanism includes an adjustment mechanism, which is respectively located inside the extension plate. The adjustment mechanism is connected by adjustment rods, and each adjustment mechanism has two adjustment rods on one side. The two ends of the adjustment rods are respectively hinged to the side wall of the adjustment mechanism. The side wall of the adjustment mechanism has symmetrically arranged hinge rods, which are centrally located and respectively hinged to the extension plate. The adjustment mechanism includes a frame, and the inner side of the frame has symmetrically arranged fixed wheels. The drive wheel is flush with the fixed wheel on the same side. The opposing sides of the adjustment rod and the opposing adjustment rod have a sliding groove four. The limiting rod is slidably arranged in the sliding groove four. The hinge rod and the extension plate are connected by a torsion spring. In the initial state, the torsion spring causes the adjustment mechanism to tilt. The adjustment mechanism and the adjustment rod have a parallelogram structure. This arrangement allows the adjustment mechanism to tilt through the torsion spring. The upper and lower fixed wheels of the adjustment mechanism clamp the upper and lower sides of the steel respectively. At the same time, the sliding groove four on the adjustment rod pulls the slider by limiting the limiting rod, so that the fixed wheel clamps the steel on the inner side, forming a fixed structure.

[0010] The frame has four symmetrically arranged sliding grooves on its top wall and two-way screws symmetrically arranged on its top. The positioning mechanism is slidably disposed within the four sliding grooves. The positioning mechanism includes a positioning rod that fits against the inner wall of the four sliding grooves. The top of the positioning rod has a screw hole that engages with the two-way screw. A ball bearing is rotatably disposed at the bottom end of the positioning rod away from the fixed wheel. A handle is provided in the middle section of the two-way screw. By rotating the two-way screw with the handle, the positioning mechanism can be moved to both sides, thereby pressing against the inner wall of the H-beam or channel steel through the ball bearing, thus centering and fixing the steel.

[0011] Preferably, control rods are provided on both sides of the fixed wheel, and the fixed wheel, control rods and adjacent adjusting rods are coaxially arranged with the hinge shaft of the adjusting mechanism. A motor is provided on the worktable, and a drive gear is provided at the output end of the motor. The driven gear meshes with the drive gear.

[0012] Furthermore, the worktable is symmetrically provided with a sliding groove, the laser cutting machine includes a support, the bottom end of the support is slidably disposed in the sliding groove, the support can slide in the sliding groove through electrical control, the top bottom wall of the support is provided with a sliding groove, and the cutting gun is slidably disposed in the sliding groove.

[0013] During operation, it is only necessary to overcome the torsion spring force by adjusting the tilt angle of the adjustment mechanism through the handle to increase the longitudinal distance between the fixed wheels and feed the steel between the fixed wheels and the drive wheel. After releasing the handle, the torsion spring rebounds, and the fixed wheels and drive wheels adaptively clamp the steel to complete the feeding. The operator only needs to adjust the positioning mechanism according to the distance between the inner walls of the H-beam or channel steel to adapt to various sizes of irregular steel.

[0014] The beneficial effects of the present invention using the above structure are as follows: The adaptive laser positioning and cutting device for irregular steel structures provided by this solution has many practical advantages. Firstly, the clamping mechanism with a parallelogram structure combined with the torsion spring reset design can adaptively clamp irregular steel with different cross-sectional dimensions. When feeding, it is only necessary to overcome the spring force of the torsion spring to adjust the clamping distance to feed the steel. After releasing, the spring rebounds and automatically completes the clamping. The operation is simple and the feeding and clamping time is greatly shortened. It can be adapted to various specifications of H-beams, channel steel and other irregular steel.

[0015] Secondly, the device is equipped with a bidirectional adjustable positioning mechanism. By rotating the bidirectional screw, the positioning rods on both sides can be moved synchronously. The ball bearings at the bottom of the positioning rods press against the inner wall of the steel profile, ensuring that the steel profile is always in the center position. This effectively avoids lateral displacement of the steel profile during processing and significantly improves the cutting positioning accuracy. At the same time, the positioning distance can be flexibly adjusted according to the inner cavity size of the steel profile, and the inner cavity adaptability range is wide.

[0016] Third, the clamping frame is integrated into the rotatable control ring. It can drive the control ring to rotate around the axis of the steel section through gear transmission. In conjunction with the drive wheel in the ring, the steel section is fed axially. The steel section can be cut in multiple circumferential directions without the need for additional independent positioning equipment. The structure is highly integrated and compact, which effectively reduces equipment costs and floor space. The overall processing efficiency and finished product consistency are significantly improved.

[0017] Fourth, the two adjustment mechanisms can independently adjust the spacing between the positioning mechanisms, improving adaptability and enabling clamping and fixing of irregularly shaped steel with inconsistent widths on one side of the slot, thus greatly expanding the scope of application.

[0023] like Figures 1-7As shown, the present invention provides an adaptive irregular steel structure laser positioning and cutting device, including a worktable 1, a conveyor belt 2, a laser cutting machine 3, and a clamping frame 4. The conveyor belt 2 is located on the top of the worktable 1, and a telescopic rod 201 is provided at the bottom of the conveyor belt 2. The telescopic rod 201 is electrically controlled. The laser cutting machine 3 is slidably located on the top of the worktable 1. The clamping frame 4 is located on the top of the worktable 1 and on the side of the laser cutting machine 3. A drive mechanism 5 is also provided on the worktable 1.

[0024] The workbench 1 is provided with a drive mechanism 5, which includes a collar 501. The clamping frame 4 is rotatably located inside the collar 501. The clamping frame 4 includes a control ring 6 and a clamping mechanism 7. The clamping mechanism 7 is symmetrically provided with a positioning mechanism 8.

[0025] The control ring 6 includes a ring body 601, with extension plates 602 symmetrically arranged at both ends of the ring body 601. A sliding groove 605 is symmetrically arranged on the inner side of the ring body 601. A slider 606 is slidably arranged in the sliding groove 605. A drive wheel 607 is provided on the opposite side of the slider 606 and another slider 606. The drive wheel 607 is an electric wheel. Limiting rods 608 are symmetrically arranged on both sides of the slider 606. A passive tooth 603 is provided on the circumferential side wall of the ring body 601. An annular groove 604 is also opened on the circumferential side wall of the ring body 601. A collar 501 is fitted on the annular groove 604.

[0026] The clamping mechanism 7 includes an adjusting mechanism 701, which is located inside the extension plate 602. The adjusting mechanism 701 is connected by adjusting rods 706. Each adjusting mechanism 701 has two adjusting rods 706 on one side, with both ends of each rod hinged to the side wall of the adjusting mechanism 701. Symmetrically arranged hinge rods 703 are located on the side wall of the adjusting mechanism 701, with the hinge rods 703 centrally located and hinged to the extension plate 602. The adjusting mechanism 701 includes a frame 702, with symmetrically arranged fixed wheels 704 on the inner side of the frame 702. A drive wheel 607 is flush with the fixed wheel 704 on the same side. The adjusting rods 706 are connected to the opposite adjusting rods. The section rod 706 has a sliding groove 707 on its opposite side. The limiting rod 608 is slidably disposed in the sliding groove 707. The hinge rod 703 is connected to the extension plate 602 by a torsion spring. In the initial state, the torsion spring causes the adjusting mechanism 701 to tilt. The adjusting mechanism 701 and the adjusting rod 706 form a parallelogram structure. This arrangement allows the adjusting mechanism 701 to tilt through the torsion spring. The upper and lower fixed wheels 704 of the adjusting mechanism 701 clamp the upper and lower sides of the steel respectively. At the same time, the sliding groove 707 on the adjusting rod 706 pulls the slider 606 by limiting the limiting rod 608, so that the fixed wheels 704 clamp the steel on the inside, forming a fixed structure.

[0027] The frame 702 has symmetrically arranged sliding grooves 710 on its top wall, and bidirectional screws 708 are symmetrically arranged on the top of the frame 702. The positioning mechanism 8 is slidably arranged in the sliding grooves 710. The positioning mechanism 8 includes a positioning rod 801, which fits against the inner wall of the sliding grooves 710. The top of the positioning rod 801 has a screw hole 802, which is threadedly engaged with the bidirectional screw 708. A ball bearing 803 is rotatably arranged at the bottom end of the positioning rod 801 on the side away from the fixed wheel 704. A handle 709 is provided in the middle section of the bidirectional screw 708. By rotating the bidirectional screw 708 through the handle 709, the positioning mechanism 8 can be moved to both sides, thereby pressing against the inner wall of the H-beam or channel steel through the ball bearing 803, so that the steel is centered and fixed.

[0028] The fixed wheel 704 is provided with control rods 705 on both sides. The fixed wheel 704, control rods 705 and adjacent adjusting rods 706 are coaxially arranged with the hinge shaft of the adjusting mechanism 701. The worktable 1 is provided with a motor 502. The output end of the motor 502 is provided with a drive gear 503. The driven gear 603 meshes with the drive gear 503.

[0029] The workbench 1 has symmetrically opened slide grooves 101. The laser cutting machine 3 includes a support 301. The bottom end of the support 301 is slidably disposed in the slide groove 101. The support 301 can slide in the slide groove 101 by electronic control. The top and bottom wall of the support 301 has a slide groove 302. The cutting gun 303 is slidably disposed in the slide groove 302.

[0030] During operation, it is only necessary to overcome the torsion spring force by adjusting the tilt angle of the adjustment mechanism 701 through the handle 709 to increase the longitudinal distance between the fixed wheels 704, and then feed the steel between the fixed wheels 704 and the drive wheel 607. After releasing the handle, the torsion spring rebounds, and the fixed wheels 704 and the drive wheel 607 adaptively clamp the steel to complete the feeding. The operator only needs to adjust the positioning mechanism 8 according to the distance between the inner walls of the H-beam or channel steel to adapt to various sizes of irregular steel.

[0031] In practical use, firstly, control motor 502 to adjust clamping frame 4 to a horizontal state via drive gear 503, and turn handle 709 to adjust the spacing of positioning mechanism 8 on adjustment mechanism 701 to the minimum. Place the steel on conveyor belt 2 in the center and transport the steel to clamping frame 4. When placing, the H-beam or channel steel should have its groove facing upward. When the steel is close to clamping frame 4, the operator pulls handle 709 by hand to overcome the resistance of torsion spring and make adjustment mechanism 701 closer to vertical, widening the longitudinal spacing between fixed wheel 704 and drive wheel 607, making it easier for the steel to enter the inner side of clamping frame 4. After the steel is fully inside, release handle 709. 09. The longitudinal distance between the fixed wheel 704 and the drive wheel 607 is reduced, clamping the steel from the top and bottom. Then, the handle 709 is rotated to expand the spacing of the positioning mechanism 8, causing it to expand to both sides. The ball bearings 803 adhere to the inner wall of the steel groove, fixing it laterally. It can only move axially inside the clamping frame 4 via the drive wheel 607. Then, the laser cutting machine 3 can be controlled to cut the steel. If multi-faceted circumferential cutting of the steel is required, the telescopic rod 201 is controlled to retract, and the motor 502 controls the drive gear 503 to drive the clamping frame 4 to rotate through the passive gear 603, thereby rotating the steel to meet the circumferential cutting requirements.
