Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to an apparatus and method for producing automotive anti-collision beams. Background Technology

[0002] A crash beam typically consists of a main beam, an energy-absorbing box, and a mounting plate. The main beam and the energy-absorbing box, as well as the energy-absorbing box and the mounting plate, are fixedly connected by welding to form a complete crash beam assembly. Welding the energy-absorbing box to both ends of the main beam is one of the key processes in the production of the crash beam assembly.

[0003] Different vehicle models use main beams with different curvature and width dimensions. However, the existing clamping mechanisms are mostly fixed structures, and the clamping position and angle cannot be adjusted. A set of clamps can only be adapted to a single model of main beam, resulting in poor versatility. When it is necessary to produce anti-collision beam assemblies of different specifications, the entire set of clamps or even the entire production line must be replaced, resulting in high equipment investment costs and long changeover time. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus and method for producing automotive anti-collision beams, which can be adapted to clamp main beams of different specifications for welding operations.

[0005] To achieve the above objectives, the present invention provides an automotive anti-collision beam production device, comprising a base, an intermediate frame, two displacement mechanisms, two side frames, two rotation mechanisms, three mounting seats, and three clamping mechanisms; The intermediate frame is fixedly mounted on the top of the base; the two displacement mechanisms are mounted on the base; the two side frames are respectively mounted on the two displacement mechanisms and are driven to move by the two displacement mechanisms; a rotation mechanism is provided on the top of each side frame; a mounting base is provided on the top of the intermediate frame and the top of each of the two rotation mechanisms; the rotation mechanism can drive the mounting base to rotate; a clamping mechanism is provided on each mounting base. The clamping mechanism includes two clamping blocks and a bidirectional lead screw; The two clamping blocks are slidably disposed on the mounting base; the bidirectional lead screw is rotatably disposed on the mounting base and is threadedly connected to the two clamping blocks respectively.

[0006] The clamping block includes a slider, two support blocks, and a pressure wheel; The slider is slidably mounted on the mounting base and threadedly connected to the bidirectional lead screw; the two support blocks are fixedly mounted on the top of the slider; the pressure wheel is rotatably mounted between the two support blocks.

[0007] The clamping mechanism further includes a support plate, an electric push rod, a pressure block, and a friction pad; The support plate is fixedly mounted on one side of the mounting base; the electric push rod is fixedly mounted on the support plate; the pressure block is fixedly mounted on the output end of the electric push rod; and the friction pad is fixedly mounted on the bottom of the pressure block.

[0008] The displacement mechanism includes a sliding seat and a drive screw; The sliding seat is slidably mounted on the base and fixedly connected to the side frame; the drive screw is rotatably mounted on the base and threadedly connected to the sliding seat.

[0009] The rotating mechanism includes a turntable, a rotating shaft, a worm gear, and a worm. The turntable is rotatably mounted on the top of the side frame and is fixedly connected to the corresponding mounting base; the rotating shaft is rotatably mounted on the top of the side frame, the top end of the rotating shaft is fixedly connected to the turntable, and the bottom end of the rotating shaft is fixedly mounted with the worm gear; the worm is rotatably mounted on the side frame and meshes with the worm gear.

[0010] The automobile anti-collision beam production device also includes a synchronous drive mechanism; The synchronous drive mechanism is mounted on the base and is used to drive the two drive screws to rotate synchronously.

[0011] The synchronous drive mechanism includes a drive shaft, a double-row sprocket, two driven sprockets, and two drive chains. The drive shaft is rotatably mounted on the base; the double-row sprockets are fixedly mounted on the drive shaft; the two driven sprockets are respectively fixedly mounted on the two drive screws; and the two drive chains are respectively mounted on the double-row sprockets and the two driven sprockets.

[0012] The automobile anti-collision beam production device also includes two lifting mechanisms; The two lifting mechanisms are mounted on the base to lift the finished anti-collision beam.

[0013] The lifting mechanism includes two guide rods, a lifting plate, and a hydraulic cylinder. The two guide rods are slidably mounted on the base and pass through the base; the lifting plate is fixedly mounted on the top of the two guide rods; the hydraulic cylinder is fixedly mounted on the top of the base, and the output end of the hydraulic cylinder is fixedly connected to the lifting plate.

[0014] This invention also provides a method for producing an automotive anti-collision beam, comprising the following steps: According to the length and curvature of the main beam to be processed, two displacement mechanisms are driven to move the two side frames back and forth to the predetermined positions, so that the clamping mechanisms on the two side frames and the clamping mechanism on the middle frame form a position difference in the front and back direction that matches the curvature of the main beam. Two rotating mechanisms are driven to rotate the corresponding mounting bases, so that the clamping mechanisms on the two side frames rotate to a predetermined angle that matches the curvature of the main beam. Place the main beam on the three mounting bases; rotate the two-way lead screws of the three clamping mechanisms respectively to drive the two clamping blocks of each clamping mechanism to move closer to each other and clamp the main beam from both sides; install the energy-absorbing boxes at both ends of the main beam respectively and perform welding operations.

[0015] This invention discloses an apparatus and method for producing automotive anti-collision beams. The base serves as the supporting foundation for the entire apparatus, bearing all other components. An intermediate frame is fixedly mounted on the top of the base, acting as a support carrier in the middle position. Two displacement mechanisms are mounted on the base, and two side frames are each driven by one of these mechanisms. Through the independent drive of the two displacement mechanisms, the two side frames can move along the front-rear direction on the base, thereby changing the relative position between the two side frames and the intermediate frame. Each side frame has a rotating mechanism at its top, which drives the component it carries to rotate around a vertical axis. When the operator drives the bidirectional lead screw to rotate, because the bidirectional lead screw has two external threads with opposite directions, the two clamping blocks move closer or further apart along the mounting base under the action of the threaded engagement, thereby clamping or releasing the main beam. In use, based on the length and curvature of the main beam to be processed, the two displacement mechanisms are driven to move the two side frames back and forth to predetermined positions, so that the clamping mechanisms on the two side frames and the clamping mechanism on the middle frame form a positional difference in the front-back direction that matches the curvature of the main beam; the two rotation mechanisms are driven to rotate the corresponding mounting seats, so that the clamping mechanisms on the two side frames rotate to a predetermined angle that matches the curvature of the main beam; the main beam is placed on the three mounting seats; the bidirectional lead screws of the three clamping mechanisms are rotated to drive the two clamping blocks of each clamping mechanism to move closer together and clamp the main beam from both sides; the energy-absorbing boxes are installed at both ends of the main beam for welding operations; The main beam is supported and clamped at three points by three clamping mechanisms. The middle clamping mechanism is fixed to the middle part of the main beam, while the left and right clamping mechanisms move the side frame back and forth through the displacement mechanism. This creates a positional difference in the front-back direction between the left and right clamping mechanisms and the middle clamping mechanism that matches the curvature of the main beam. At the same time, the left and right clamping mechanisms drive the mounting base to rotate through the rotation mechanism, so that the clamping angle of the left and right clamping mechanisms is consistent with the tangent direction of the arc surface of the main beam at the clamping point. Each clamping mechanism drives the two clamping blocks to move closer or further apart through the bidirectional lead screw to adapt to different thicknesses of the main beam, thereby enabling the clamping of main beams of different specifications for welding operations.

[0025] This invention provides an automotive anti-collision beam production device: comprising a base 1, an intermediate frame 2, two displacement mechanisms 3, two side frames 4, two rotating mechanisms 5, three mounting seats 6, and three clamping mechanisms 7; each clamping mechanism 7 includes two clamping blocks 701 and a bidirectional lead screw 702; each clamping block 701 includes a slider 70101, two support blocks 70102, and a pressure wheel 70103; the clamping mechanism 7 also includes a support plate 703, an electric push rod 704, a pressure block 705, and a friction pad 706; each displacement mechanism 3 includes a sliding seat 301 and a drive... The lead screw 302; the rotating mechanism 5 includes a turntable 501, a rotating shaft 502, a worm gear 503, and a worm 504; the automotive anti-collision beam production device also includes a synchronous drive mechanism 8; the synchronous drive mechanism 8 includes a drive shaft 801, a double-row sprocket 802, two driven sprockets 803, and two drive chains 804; the automotive anti-collision beam production device also includes two lifting mechanisms 9; the lifting mechanism 9 includes two guide rods 901, a lifting plate 902, and a hydraulic cylinder 903; the aforementioned scheme can be adapted to clamp main beams of different specifications for welding operations.

[0026] Furthermore, the intermediate frame 2 is fixedly mounted on the top of the base 1; two displacement mechanisms 3 are mounted on the base 1; two side frames 4 are respectively mounted on the two displacement mechanisms 3, and are respectively driven to move by the two displacement mechanisms 3; a rotating mechanism 5 is provided on the top of each side frame 4; a mounting base 6 is provided on the top of the intermediate frame 2 and the top of the two rotating mechanisms 5; the rotating mechanism 5 can drive the mounting base 6 to rotate; a clamping mechanism 7 is provided on each mounting base 6; two clamping blocks 701 are slidably mounted on the mounting base 6; the bidirectional lead screw 702 is rotatably mounted on the mounting base 6 and is threadedly connected to the two clamping blocks 701 respectively.

[0027] In this embodiment, the base 1 serves as the supporting foundation for the entire device, supporting all other components. The intermediate frame 2 is fixedly mounted on the top of the base 1, acting as a supporting carrier in the middle position. Two displacement mechanisms 3 are mounted on the base 1, and the two side frames 4 are driven by the two displacement mechanisms 3 respectively. Through the independent drive of the two displacement mechanisms 3, the two side frames 4 can move along the front-back direction on the base 1, thereby changing the relative position between the two side frames 4 and the intermediate frame 2. Each side frame 4 has a rotating mechanism 5 at its top, which drives the component supported above it to rotate around a vertical axis. One end of the bidirectional lead screw 702 is equipped with a knob. When the operator drives the bidirectional lead screw 702 to rotate, because the bidirectional lead screw 702 has two external threads with opposite directions, the two clamping blocks 701 move closer or further apart along the mounting base 6 under the action of the threaded engagement, thereby clamping or releasing the main beam. In use, according to the length and curvature of the main beam to be processed, the two displacement mechanisms 3 are driven to move the two side frames 4 back and forth to a predetermined position, so that the clamping mechanisms 7 on the two side frames 4 and the clamping mechanism 7 on the middle frame 2 form a positional difference in the front-back direction that matches the curvature of the main beam; the two rotation mechanisms 5 are driven to rotate the corresponding mounting seats 6, so that the clamping mechanisms 7 on the two side frames 4 rotate to a predetermined angle that matches the curvature of the main beam; the main beam is placed on the three mounting seats 6; the bidirectional lead screws 702 of the three clamping mechanisms 7 are rotated to drive the two clamping blocks 701 of each clamping mechanism 7 to move closer to each other and clamp the main beam from both sides; the energy-absorbing boxes are installed at both ends of the main beam for welding operations; The main beam is supported and clamped at three points by three clamping mechanisms 7. The middle clamping mechanism 7 is fixedly clamped to the middle part of the main beam. The left and right clamping mechanisms 7 drive the side frame 4 to move back and forth through the displacement mechanism 3, so that the left and right clamping mechanisms 7 and the middle clamping mechanism 7 form a positional difference in the front-back direction that matches the curvature of the main beam. At the same time, the left and right clamping mechanisms 7 drive the mounting base 6 to rotate through the rotation mechanism 5, so that the clamping angle of the left and right clamping mechanisms 7 is consistent with the tangent direction of the arc surface of the main beam at the clamping point. Each clamping mechanism 7 drives the two clamping blocks 701 to move closer or further away through the bidirectional lead screw 702 to adapt to different thicknesses of the main beam, so as to be able to clamp main beams of different specifications for welding operations.

[0028] Furthermore, the slider 70101 is slidably disposed on the mounting base 6 and threadedly connected to the bidirectional lead screw 702; the two support blocks 70102 are fixedly disposed on the top of the slider 70101; and the pressure wheel 70103 is rotatably disposed between the two support blocks 70102.

[0029] In this embodiment, the slider 70101 is slidably disposed on the mounting base 6, and the slider 70101 is threadedly connected to the bidirectional lead screw 702. When the bidirectional lead screw 702 rotates, the slider 70101 slides along the mounting base 6 under the threaded drive. Two support blocks 70102 are fixedly disposed on the top of the slider 70101, and the two support blocks 70102 are spaced apart on the slider 70101 to form a support structure. The pressure wheel 70103 is rotatably disposed between the two support blocks 70102, that is, both ends of the pressure wheel 70103 are rotatably connected to the two support blocks 70102 respectively, and the pressure wheel 70103 can rotate freely around its own axis. When clamping the main beam, the wheel surface of the clamping wheel 70103 contacts the surface of the main beam. Since the clamping wheel 70103 can rotate, scratches on the surface of the main beam can be avoided during clamping. At the same time, a rolling friction fit is formed between the wheel surface of the clamping wheel 70103 and the main beam, which ensures the stability of clamping and reduces clamping resistance. Especially for main beams of the same specifications in the same batch, after adjusting the distance between the two clamping wheels 70103 to a clamping distance that matches the thickness of the main beam by using the bidirectional lead screw 702 during the first clamping, subsequent loading only requires directly aligning the main beam from above and inserting it between the two clamping wheels 70103 to complete the clamping, without having to repeatedly rotate the bidirectional lead screw 702. When unloading, only the main beam needs to be lifted upwards to be removed from between the two clamping wheels 70103, without having to rotate the bidirectional lead screw 702 again to release the clamping wheels 70103, which greatly simplifies the loading and unloading operations and improves the work efficiency in batch production. When it is necessary to replace the main beam with a different thickness, simply rotate the bidirectional lead screw 702 again to adjust the distance between the two clamping rollers 70103.

[0030] Furthermore, the support plate 703 is fixedly disposed on one side of the mounting base 6; the electric push rod 704 is fixedly disposed on the support plate 703; the pressure block 705 is fixedly disposed on the output end of the electric push rod 704; and the friction pad 706 is fixedly disposed on the bottom of the pressure block 705.

[0031] In this embodiment, after the main beam is clamped from both sides by the two clamping blocks 701, the electric push rod 704 is activated, driving the pressure block 705 to move downwards, causing the friction pad 706 to press against the top surface of the main beam, thereby applying a downward clamping force to the top of the main beam. The friction pad 706 is made of elastic friction material, which can increase the friction between the main beam and the main beam, preventing the main beam from shifting during welding, and avoiding surface damage to the main beam caused by rigid contact between the pressure block 705 and the main beam. Through the combined action of the horizontal clamping of the two clamping blocks 701 and the vertical clamping driven by the electric push rod 704, multi-directional limiting and fixing of the main beam is achieved, ensuring the positional stability of the main beam during welding.

[0032] Furthermore, the sliding seat 301 is slidably disposed on the base 1 and fixedly connected to the side frame 4; the drive screw 302 is rotatably disposed on the base 1 and threadedly connected to the sliding seat 301.

[0033] In this embodiment, when the drive screw 302 rotates, the sliding seat 301 slides along the base 1 under the threaded drive, thereby driving the side frame 4 to move in the front-back direction. A knob is provided at one end of the drive screw 302.

[0034] Furthermore, the turntable 501 is rotatably mounted on the top of the side frame 4 and is fixedly connected to the corresponding mounting base 6; the rotating shaft 502 is rotatably mounted on the top of the side frame 4, the top end of the rotating shaft 502 is fixedly connected to the turntable 501, and the bottom end of the rotating shaft 502 is fixedly mounted with the worm gear 503; the worm 504 is rotatably mounted on the side frame 4 and meshes with the worm gear 503.

[0035] In this embodiment, a knob is provided at one end of the worm gear 504. When the operator rotates the worm gear 504, the worm gear 504 drives the meshing worm wheel 503 to rotate. The worm wheel 503 drives the turntable 501 to rotate through the rotating shaft 502, which in turn drives the mounting base 6 and the clamping mechanism 7 disposed on the mounting base 6 to rotate, thereby adjusting the clamping angle of the clamping mechanism 7. Through the self-locking characteristics of the worm wheel 503 and the worm gear 504, the clamping mechanism 7 can maintain its position locked after rotating to a predetermined angle, preventing deflection due to vibration during the welding process.

[0036] Furthermore, the synchronous drive mechanism 8 is mounted on the base 1 and is used to drive the two drive screws 302 to rotate synchronously.

[0037] In this embodiment, since the main beam is symmetrical, the displacements of the two side clamping mechanisms 7 should be consistent. Therefore, the synchronous drive mechanism 8 simultaneously drives the two drive screws 302 to rotate at the same speed and in the same direction, thereby causing the two side frames 4 to move symmetrically relative to the middle frame 2, ensuring the positioning accuracy of the main beam in the width direction.

[0038] Furthermore, the drive shaft 801 is rotatably mounted on the base 1; the double-row sprocket 802 is fixedly mounted on the drive shaft 801; the two driven sprockets 803 are respectively fixedly mounted on the two drive screws 302; and the two drive chains 804 are respectively mounted on the double-row sprocket 802 and the two driven sprockets 803.

[0039] In this embodiment, a crank is provided at one end of the drive shaft 801; when the drive shaft 801 rotates, the double-row sprocket 802 drives the two driven sprockets 803 to rotate synchronously through the two drive chains 804, and the two driven sprockets 803 drive the two drive screws 302 to rotate synchronously, thereby realizing the synchronous displacement of the two sliding seats 301.

[0040] Furthermore, two lifting mechanisms 9 are mounted on the base 1 to lift the finished anti-collision beam.

[0041] In this embodiment, after the welding operation is completed and the pressure block 705 is released, the two lifting mechanisms 9 lift upwards simultaneously, lifting the welded anti-collision beam assembly from the clamping mechanism 7, so that the anti-collision beam assembly is disengaged from the clamping mechanism 7, making it easier for operators or robots to remove the workpiece, thereby improving production efficiency.

[0042] Furthermore, the two guide rods 901 are slidably disposed on the base 1 and pass through the base 1; the lifting plate 902 is fixedly disposed on the top of the two guide rods 901; the hydraulic cylinder 903 is fixedly disposed on the top of the base 1, and the output end of the hydraulic cylinder 903 is fixedly connected to the lifting plate 902.

[0043] In this embodiment, when the hydraulic cylinder 903 is activated, its output end extends upward, pushing the lifting plate 902 upward. The two guide rods 901 slide upward synchronously with the lifting plate 902, providing guidance and ensuring the lifting plate 902 remains horizontal during lifting. Guided by the two guide rods 901 and driven by the hydraulic cylinder 903, the lifting plate 902 can smoothly lift the anti-collision beam assembly from the clamping mechanism 7 for easy removal.

[0044] In this embodiment, an automotive anti-collision beam production device is used such that, according to the length and curvature of the main beam to be processed, two displacement mechanisms 3 are driven to move two side frames 4 back and forth to predetermined positions, so that the clamping mechanisms 7 on the two side frames 4 and the clamping mechanism 7 on the intermediate frame 2 form a positional difference in the front-back direction that matches the curvature of the main beam; two rotation mechanisms 5 are driven to rotate the corresponding mounting seats 6, so that the clamping mechanisms 7 on the two side frames 4 rotate to a predetermined angle that matches the curvature of the main beam; the main beam is placed on three mounting seats 6; the bidirectional lead screws 702 of the three clamping mechanisms 7 are rotated to drive the two clamping blocks 701 of each clamping mechanism 7 to move closer together and clamp the main beam from both sides; energy-absorbing boxes are installed at both ends of the main beam for welding operations; The main beam is supported and clamped at three points by three clamping mechanisms 7. The middle clamping mechanism 7 is fixedly clamped to the middle part of the main beam. The left and right clamping mechanisms 7 drive the side frame 4 to move back and forth through the displacement mechanism 3, so that the left and right clamping mechanisms 7 and the middle clamping mechanism 7 form a positional difference in the front-back direction that matches the curvature of the main beam. At the same time, the left and right clamping mechanisms 7 drive the mounting base 6 to rotate through the rotation mechanism 5, so that the clamping angle of the left and right clamping mechanisms 7 is consistent with the tangent direction of the arc surface of the main beam at the clamping point. Each clamping mechanism 7 drives the two clamping blocks 701 to move closer or further away through the bidirectional lead screw 702 to adapt to different thicknesses of the main beam, so as to be able to clamp main beams of different specifications for welding operations.

[0045] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 6 ,in, Figure 6 This is a flowchart illustrating the second embodiment of the present invention.

S2: Drive the two rotating mechanisms 5 respectively to drive the corresponding mounting bases 6 to rotate, so that the clamping mechanisms 7 on the two side frames 4 rotate to a predetermined angle that matches the curvature of the main beam; S3: Place the main beam on the three mounting seats 6; rotate the two-way lead screws 702 of the three clamping mechanisms 7 respectively, driving the two clamping blocks 701 of each clamping mechanism 7 to move closer to each other and clamp the main beam from both sides; install the energy-absorbing boxes at both ends of the main beam respectively and perform welding operations.
