Description

Technical Field

[0001] The present invention relates to the technical field of frame processing, and particularly relates to a cutting device for frame production. Background Art

[0002] An automobile frame is a basic structural component of an automobile and is the skeleton of the automobile. It is used to support and install assemblies and components such as the automobile engine, body, and chassis, bear the load of the automobile, and ensure the accurate relative positions between the assemblies and components. The main raw materials of the automobile frame include high-strength steel plates, galvanized thin steel strips, aluminum alloys, and carbon fibers. When producing an automobile frame using steel plates, it is necessary to splice two steel plates or connect the two ends of one steel plate. Therefore, a welding device is required to weld the steel plates. Before welding, in order to ensure the welding quality, it is necessary to cut the ends of the two steel plates.

[0003] The Chinese patent application document with the publication number CN119609206A discloses a metal sheet cutting device. The metal sheet cutting device includes a workbench. Two cutting tables are arranged on the top of the workbench. A metal sheet is placed above the cutting tables. A cutting knife plate is arranged directly above the metal sheet. Mounting frames are fixedly installed on both sides of the workbench. A fixed table is fixedly connected between the two mounting frames. A hydraulic cylinder is fixedly installed on the top of the fixed table. The output end of the hydraulic cylinder is fixedly connected to the top of the cutting knife plate. Connecting rods are fixedly connected to both sides of the cutting knife plate. One end of each connecting rod is fixedly connected to an inner slider one. The two inner sliders one are respectively slidably connected to the two fixed tables. Lifting components are arranged on both sides of the cutting knife plate. The lifting components are used to drive the two cutting tables to tilt. A vibration component is arranged inside the lifting components. The vibration component is used to vibrate the cutting tables during the tilting process. An external positioning component is arranged above the cutting tables.

[0004] However, the structural design of the above related technology: Although it can clean up the slag after cutting, the angle of the cutting knife plate for cutting the sheet is fixed. During cutting, it is inconvenient to detect the inclination of the end of the steel plate, so it is inconvenient to adjust according to the inclination of the end of the other sheet, resulting in the need to cut the ends of both sheets before welding, which is likely to cause waste of materials and thus increase the production cost.

[0005] Therefore, we propose a cutting device for frame production to facilitate solving the problems raised above. Summary of the Invention

[0006] The present invention provides a cutting device for frame production, aiming to solve the problem in the related technology that when cutting steel plates, both steel plates need to be cut, which is likely to cause waste of materials.

[0007] The cutting device for frame production of the present invention includes a base, a welding assembly provided on the base, and two feeding assemblies. A guiding plate is provided between the two feeding assemblies, and a support frame located above the guiding plate is arranged at the tops of the two feeding assemblies. The cutting device for frame production further includes:

[0008] An angle detection mechanism, which includes a lifting plate guidingly assembled on the support frame in the up-and-down direction, and further includes a rotating rod rotatably installed on the lifting plate around an axis extending in the up-and-down direction. Two detection rods are provided on the rotating rod, and the two detection rods are used to be pushed by both sides of the end of one of the steel plates to drive the rotating rod to rotate. Installation boxes are installed on both sides of the lifting plate, and detection plates are elastically slidably connected in the transverse direction on the two installation boxes. The detection plates are in contact with the top of the guiding plate to detect the position of the end of the other steel plate;

[0009] A cutting mechanism, which is guidingly assembled on the support frame in the up-and-down direction. The cutting mechanism is used to cut the end of the other steel plate. The cutting mechanism includes a cutting knife for rotating around an axis extending in the up-and-down direction;

[0010] A transmission assembly, connecting the rotating rod and the cutting knife. When the rotating rod rotates, the cutting knife is driven to rotate synchronously through the transmission assembly.

[0011] The ends of the two steel plates are conveyed to the guiding plate through the two feeding assemblies. During the conveying process, the two detection rods are pushed by both sides of the end of one of the steel plates to drive the rotating rod to rotate. At the same time, the rotating rod drives the cutting knife to rotate so that the angle of the cutting knife is the same as the inclination angle of the end of the detected steel plate. During the detection process, the two detection plates detect the position of the end of the other steel plate. When both detection plates are in contact with the end of the other steel plate, the cutting knife cuts the end of the other steel plate so that the inclination angles of the ends of the two steel plates are the same.

[0012] Preferably, a driving assembly is arranged on one side of the top of the support frame. A locking assembly is connected to the driving assembly, and the locking assembly is arranged on the top of the cutting knife. The driving assembly drives the cutting knife to lift through the locking assembly;

[0013] The locking assembly includes a connecting seat arranged on the top of the cutting knife. The driving assembly includes a connecting shaft located at the bottom. The connecting shaft is rotatably connected to the connecting seat. The locking assembly further includes two limiting members arranged on the connecting seat. The two limiting members clamp the connecting shaft after the cutting knife rotates in place to prevent the cutting knife from rotating.

[0014] When both detection plates are in contact with the end of the steel plate, the driving assembly drives the cutting knife to move downwards to cut the end of the steel plate. During the downward movement of the cutting knife, the two limiting members clamp the connecting shaft to prevent the cutting knife from rotating.

[0015] Preferably, a horizontal plate is fixedly installed on the support frame. A fixed cylinder is fixed on the horizontal plate. A rotating rod is fixed at the top of the cutting knife. The connecting seat is fixed on the rotating rod, and the rotating rod penetrates into the fixed cylinder;

[0016] The limiting member includes a limiting rod slidably inserted into the inner wall of the connecting seat. A clamping plate is fixed at one end of the limiting rod located inside the connecting seat. An elastic member II is press-fitted between the clamping plate and the connecting seat. When the connecting seat moves down to the fixed cylinder, the limiting rod is pressed by the inner wall of the connecting seat, causing the clamping plate to clamp the connecting shaft.

[0017] During the downward movement of the cutting knife, the connecting seat gradually enters the fixed cylinder. The fixed cylinder presses the limiting rod, and the limiting rod drives the clamping plate to approach the connecting shaft to clamp the connecting shaft.

[0018] Preferably, the transmission assembly includes a first transmission wheel, a second transmission wheel, a rotating shaft, a first gear, a second gear, and a third gear. The first transmission wheel is installed on the outside of the rotating rod. The first transmission wheel and the second transmission wheel are connected by a belt drive. The rotating shaft is installed in the middle of the second transmission wheel. The rotating shaft is rotatably connected to the bottom side of the lifting plate. The first gear is installed at the bottom end of the rotating shaft;

[0019] The second gear is fixed on the rotating rod. The third gear is rotatably installed on the horizontal plate. The third gear meshes with both the first gear and the second gear.

[0020] Preferably, a driven assembly is drivingly connected to the driving assembly, and the driven assembly is connected to the top of the lifting plate.

[0021] Preferably, the driven assembly includes a second lead screw drivingly connected to the driving assembly. A second threaded plate is threadedly connected to the outside of the second lead screw. A third sliding rod is installed at the bottom of the second threaded plate. The third sliding rod is vertically slidably connected to the support frame. A connecting frame is sleeved on the outside of the second lead screw. The top of the second threaded plate is in contact with the inner top wall of the connecting frame. The bottom of the connecting frame penetrates the top of the support frame and is installed on the top of the lifting plate.

[0022] When the driving assembly drives the cutting knife to move down, the second lead screw drives the second threaded plate to move down. At this time, supported by the detection rod and the installation box, the connecting frame connected to the lifting plate does not move. After the cutting knife cuts the steel plate, the driving assembly first drives the cutting knife to move up until it returns to its original position, and then the driving assembly continues to drive the cutting knife to move up. When the cutting knife continues to move up after returning to its original position, the second threaded plate drives the lifting plate to move up through the connecting frame. The lifting plate drives the detection rod and the detection plate to move up, avoiding affecting the subsequent conveying of the steel plate.

[0023] Preferably, the driving assembly includes a first lead screw. Transmission wheels III are installed on the outer sides of the top ends of the first lead screw and the second lead screw respectively. The two transmission wheels III are connected by a belt drive.

[0024] Preferably, a first slide bar is installed on the inner wall of the installation box. A slide sleeve is slidably connected to the outer side of the first slide bar. An elastic member I is arranged between the inner wall of the installation box and the slide sleeve. The slide sleeve is installed on the top of the detection plate to drive the detection plate to reset.

[0025] During the process of the detection plate contacting the steel plate, the elastic member I will be gradually compressed. When the detection plate moves upward, the detection plate gradually disengages from the end of the steel plate. At this time, the elastic member I resets, and at the same time, the elastic member I drives the detection plate to reset through the slide sleeve, so as to facilitate the next detection.

[0026] By adopting the above technical solution, the beneficial effects of the present invention are as follows: During the process of the two feeding components driving the ends of the two steel plates to be conveyed to the guide plate, the two detection rods are pushed by the two sides of the end of one of the steel plates to drive the rotating rod to rotate. At the same time, the rotating rod drives the cutting knife to rotate, so that the angle of the cutting knife is the same as the inclination angle of the end of the steel plate to be detected. During the detection process, the two detection plates detect the position of the end of the other steel plate. When both detection plates are in contact with the end of the other steel plate, the driving component drives the cutting knife to cut the end of the other steel plate, so that the inclination angles of the ends of the two steel plates are the same, which is convenient for splicing the two steel plates. And during cutting, only one steel plate needs to be cut, thereby reducing material loss. Description of the Drawings

[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0042] As Figures 1 to 7As shown in the figure, the cutting device for the frame production of the present invention includes a base 11. On one side of the top of the base 11, a welding component 21 is installed. In this embodiment, the welding component 21 is a welding robot. In other embodiments, the welding component 21 is a handheld welding gun for welding steel plates. On the other side of the top of the base 11, two feeding components 31 are provided to drive two steel plates to approach each other. A guiding plate 33 is arranged between the two feeding components 31. On the top of the two feeding components 31, a support frame 34 is provided. An angle detection mechanism is arranged on the support frame 34. The angle detection mechanism includes a first detection component 41 and a second detection component 44. The first detection component 41 and the second detection component 44 are respectively arranged on both sides of the top of the guiding plate 33 to detect the end faces of the steel plates. On one side of the inner wall of the support frame 34, a cutting mechanism is provided to cut the ends of the steel plates. A driving mechanism is arranged on the cutting mechanism.

[0043] The two feeding components 31 transport the ends of the two steel plates to the guiding plate 33. During the transportation process, the first detection component 41 detects the end of one of the steel plates, and at the same time adjusts the angle of the cutting mechanism so that the angle of the cutting mechanism is the same as the inclination angle of the end of one of the steel plates. Then, the driving mechanism drives the cutting mechanism to cut the end of the other steel plate, so that the inclination angles of the ends of the two steel plates are the same, which is convenient for splicing the two steel plates. And during cutting, only one steel plate needs to be cut, thus reducing material loss.

[0044] As Figures 1 to 2 shown in the figure, the first detection component 41 includes a mounting plate 411, a rotating rod 413, and two detection rods 412. The mounting plate 411 is installed at the bottom end of the rotating rod 413. The two detection rods 412 are respectively installed on both sides of the bottom of the mounting plate 411. The two detection rods 412 can rotate along the axis of the rotating rod 413. The top end of the rotating rod 413 is rotatably connected to a lifting plate 43. A torsion spring (not shown in the figure) is arranged between the rotating rod 413 and the lifting plate 43 to drive the detection rod 412 to reset.

[0045] As Figures 2 to 3 shown in the figure, a transmission component 42 is arranged on the outside of the rotating rod 413. The transmission component 42 includes a first transmission wheel 421, a second transmission wheel 422, a rotating shaft 423, and a first gear 424. The first transmission wheel 421 is installed on the outside of the rotating rod 413. The first transmission wheel 421 and the second transmission wheel 422 are connected by a belt drive. The middle of the second transmission wheel 422 is installed with a rotating shaft 423. The top end of the rotating shaft 423 is rotatably connected to one side of the bottom of the lifting plate 43. The first gear 424 is installed at the bottom end of the rotating shaft 423.

[0046] During the conveying process of the steel plate, when the end of the steel plate is tilted, the steel plate first contacts one of the detection rods 412. As the steel plate continues to move, the steel plate drives the mounting plate 411 to rotate through the detection rod 412, so that both detection rods 412 contact the end of the steel plate, thereby detecting the tilt angle of the steel plate. At this time, the conveying of the steel plate stops. When the ends of the steel plate are flush, the mounting plate 411 does not rotate.

[0047] As Figure 1 , Figure 2 and Figure 4 shown, the second detection assembly 44 includes two detection plates 444. In the advancing direction of the end of the steel plate, the detection rod 412 and the detection plate 444 are located on the same straight line. The bottom of the detection plate 444 is in contact with the top of the material guiding plate 33. A sliding sleeve 443 is installed on the top of the detection plate 444, and a first sliding rod 441 is slidably connected inside the sliding sleeve 443.

[0048] As Figure 2 and Figure 4 shown, an installation box 445 is arranged on the outer side of the first sliding rod 441. The two ends of the first sliding rod 441 are respectively installed on both sides of the inner wall of the installation box 445. A sliding groove 448 for the detection plate 444 to slide is opened on one side of the installation box 445. A first elastic member 442 is arranged on the outer side of the first sliding rod 441. In this embodiment, the first elastic member 442 is a spring. The first elastic member 442 is arranged between the inner wall of the installation box 445 and the sliding sleeve 443 to drive the detection plate 444 to reset. A pressure sensor (not shown in the figure) is arranged at the end of the first elastic member 442. When both detection plates 444 contact the end of the steel plate, the driving mechanism drives the cutting mechanism to cut the steel plate in contact with the detection plate 444.

[0049] Continue to refer to Figure 2 and Figure 4 shown, a fixing rod 446 is installed on the top of the installation box 445, a fixing plate 447 is installed at the top of the fixing rod 446, and the fixing plate 447 is installed on one side of the lifting plate 43.

[0050] As Figure 1 and Figure 2 shown, the cutting mechanism includes a cutting assembly 61. A locking assembly 62 is arranged on the top of the cutting assembly 61, and a supporting assembly 63 is arranged on the outer side of the cutting assembly 61.

[0051] As Figure 1 , Figure 2 and Figure 5 shown, the cutting assembly 61 includes a cutting tool 611. A rotating rod 612 is installed on the top of the cutting tool 611, a second gear 613 is installed on the outer side of the top of the rotating rod 612, and the cutting tool 611 is arranged between two installation boxes 445.

[0052] AsFigure 2 , Figure 5 and Figure 6 As shown, the locking assembly 62 includes a connecting seat 621 and two limit members. The connecting seat 621 is installed at the top of the rotating rod 612. The connecting seat 621 is rotatably connected to the driving mechanism. The driving mechanism drives the cutting knife 611 to move downward through the connecting seat 621. When the cutting knife 611 moves downward, the limit members enter the supporting assembly 63. At this time, under the action of the supporting assembly 63, the two limit members clamp the driving mechanism to prevent the adjusted cutting knife 611 from rotating.

[0053] like Figure 6 As shown, the limiting member includes a limiting rod 622, a clamping plate 623 and an elastic member 624. The clamping plate 623 is arc-shaped and is located inside the connecting seat 621. One end of the limiting rod 622 is installed on the outside of the clamping plate 623. The other end of the limiting rod 622 passes through the connecting seat 621 and extends to the outside of the connecting seat 621. The other end of the limiting rod 622 has an arc surface. The elastic member 624 is arranged between the outside of the clamping plate 623 and the inner wall of the connecting seat 621 to drive the clamping plate 623 to reset. In this embodiment, the elastic member 624 is a spring. In other embodiments, the elastic member 624 is an elastic sheet.

[0054] like Figure 2 and Figure 5 As shown, the support assembly 63 includes a fixed cylinder 631, a horizontal plate 632 and a gear three 633. The horizontal plate 632 is installed on the outer side of the top of the fixed cylinder 631, and one side of the horizontal plate 632 is installed on the inner wall side of the support frame 34. The gear three 633 is rotatably connected to the bottom side of the horizontal plate 632. The gear three 633 can be engaged with the gear one 424 and the gear two 613 respectively.

[0055] When the cutting blade 611 moves downward, the connecting seat 621 enters the interior of the fixing tube 631 , and at this time, the fixing tube 631 squeezes the limiting rod 622 , and at the same time, the limiting rod 622 drives the clamping plate 623 to clamp on the driving mechanism.

[0056] like Figure 2 , Figures 5 to 7 As shown, the driving mechanism includes a driving component 51 arranged on one side of the top of the support frame 34, one side of the driving component 51 is transmission-connected with a driven component 52, the driving component 51 is rotationally connected to the connecting seat 621, and the driven component 52 is arranged on the other side of the top of the support frame 34.

[0057] like Figure 2 and Figure 7As shown, the driving assembly 51 includes a fixing frame 511, a driving member 512, a first lead screw 513, and a connecting shaft 517. The fixing frame 511 is installed on one side of the top of the support frame 34. In this embodiment, both the support frame 34 and the fixing frame 511 are U-shaped. In other embodiments, the fixing frame 511 is L-shaped. The driving member 512 is installed on the top of the fixing frame 511. The top end of the first lead screw 513 is rotatably connected to the inner top wall of the fixing frame 511, and the driving shaft of the driving member 512 is installed at the top end of the first lead screw 513. In this embodiment, the driving member 512 is a servo motor.

[0058] As Figure 2 , Figure 6 and Figure 7 shown, a first threaded plate 514 is threadedly connected to the outside of the first lead screw 513. Two second sliding rods 515 are installed at the bottom of the first threaded plate 514. The bottom ends of the second sliding rods 515 are installed with a connecting plate 516. The connecting plate 516 is located below the inner top wall of the support frame 34. The second sliding rods 515 are slidably connected to the support frame 34 in the vertical direction. The connecting shaft 517 is installed at the bottom of the connecting plate 516, and the connecting shaft 517 is rotatably connected to the middle of the inner bottom wall of the connecting seat 621.

[0059] The driving member 512 drives the connecting shaft 517 on the connecting plate 516 to move downward through the first threaded plate 514 on the first lead screw 513. At this time, the connecting shaft 517 drives the cutting knife 611 to move downward through the rotating rod 612 on the connecting seat 621 to cut the steel plate. After cutting, the waste is taken out to facilitate subsequent operations. When the connecting seat 621 enters the fixed cylinder 631, the fixed cylinder 631 presses the limiting rod 622, and at the same time, the limiting rod 622 drives the clamping plate 623 to clamp on the connecting shaft 517.

[0060] As Figure 2 and Figure 7 shown, the driven assembly 52 includes a second lead screw 521 rotatably connected to the top of the support frame 34. Transmission wheels three 518 are installed on the outer sides of the top ends of the first lead screw 513 and the second lead screw 521, and the two transmission wheels three 518 are connected by a belt drive.

[0061] Continue to refer to Figure 2 and Figure 7 shown, a second threaded plate 522 is threadedly connected to the outside of the second lead screw 521. A third sliding rod 524 is installed at the bottom of the second threaded plate 522. The third sliding rod 524 is slidably connected to the support frame 34 in the vertical direction. A connecting frame 523 is sleeved on the outside of the second lead screw 521. The top of the second threaded plate 522 is in contact with the inner top wall of the connecting frame 523. The bottom of the connecting frame 523 penetrates through the top of the support frame 34 and is installed on the top of the lifting plate 43.

[0062] During the downward movement of the cutting knife 611, the lead screw one 513 drives the lead screw two 521 to rotate. At the same time, the lead screw two 521 drives the threaded plate two 522 to move downward. When the cutting knife 611 resets, the threaded plate two 522 resets simultaneously. Then, the driving member 512 drives the cutting knife 611 to continue moving upward through the lead screw one 513. At this time, the threaded plate two 522 drives the connecting frame 523 to move upward. During the upward movement of the connecting frame 523, it drives the mounting plate 411 and the mounting box 445 to move upward simultaneously through the lifting plate 43, so that the detection rod 412 and the detection plate 444 are separated from the steel plate, enabling the two steel plates to be spliced.

[0063] As Figure 1 and Figure 2 shown, the feeding assembly 31 includes a fixed frame 311 and a plurality of conveying rollers 313. The bottom of the fixed frame 311 is installed on one side of the top of the base 11. The plurality of conveying rollers 313 are rotatably connected inside the fixed frame 311. The plurality of conveying rollers 313 are drivingly connected to each other. One end of one of the conveying rollers 313 is connected to a first motor. The first motor on the conveying roller 313 is installed on one side of the fixed frame 311. The plurality of conveying rollers 313 are evenly distributed along the length direction of the fixed frame 311. An opening 312 is provided on one side of the fixed frame 311 to facilitate the removal of the welded steel plate.

[0064] Continuing to refer to Figure 1 and Figure 2 shown, a pressing component 32 is provided on the fixed frame 311. The pressing component 32 includes a telescopic member 321, a mounting frame 322, and a plurality of connecting rollers 323. The telescopic member 321 is installed on the top of the fixed frame 311. In this embodiment, the telescopic member 321 is a cylinder. In other embodiments, the telescopic member 321 is a hydraulic cylinder or an electric telescopic rod. The mounting frame 322 is installed at the movable end of the telescopic member 321. The shape of the mounting frame 322 is U-shaped. The mounting frame 322 is located inside the fixed frame 311 and above the conveying rollers 313. The plurality of connecting rollers 323 are rotatably connected inside the mounting frame 322. The plurality of connecting rollers 323 are drivingly connected to each other. The plurality of connecting rollers 323 are evenly distributed along the length direction of the mounting frame 322. One of the connecting rollers 323 is connected to a second motor. The second motor on the connecting roller 323 is installed on one side of the mounting frame 322.

[0065] Working principle: By rotating the conveying roller 313 and the connecting roller 323, two steel plates can be driven to move onto the guide plate 33. During the movement of the two steel plates, the end of one of the steel plates is detected by the detection rod 412. At the same time, the rotating rod 413 drives the gear three 633 to rotate through the gear one 424, and the gear three 633 drives the cutting knife 611 on the rotating rod 612 to rotate through the gear two 613, so that the inclination angle of the cutting knife 611 is the same as that of the end of the detected steel plate. During the process of the detection rod 412 contacting one of the steel plates, if the end of the other steel plate is inclined, it will first contact one of the detection plates 444. When both detection plates 444 contact the steel plate, the driving member 512 drives the connecting shaft 517 on the connecting plate 516 to move downward through the threaded plate one 514 on the lead screw one 513. At this time, the connecting shaft 517 drives the cutting knife 611 to move downward to cut the other steel plate, and at this time, the inclination angles of the ends of the two steel plates are the same.

[0066] After the steel plate is cut, the driving member 512 drives the cutting knife 611 to move upward by rotating the lead screw one 513. After the cutting knife 611 is reset, the driving member 512 continues to drive the cutting knife 611 to move upward through the lead screw one 513. At the same time, the lead screw one 513 drives the threaded plate two 522 on the lead screw two 521 to move upward through the transmission wheel three 518. During the upward movement of the threaded plate two 522, it drives the lifting plate 43 to move upward through the connecting frame 523. At this time, the lifting plate 43 drives the detection rod 412 and the detection plate 444 to move upward above the steel plate.

[0067] Then, the two steel plates are continuously conveyed by the conveying roller 313 and the connecting roller 323 so that the two steel plates can be aligned. After the two steel plates are aligned, the two steel plates are welded by the welding assembly 21 to realize the butt joint of the two steel plates. After the steel plates are welded, the steel plates are taken out from the opening 312 of the fixed frame 311.
