DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] like Figure 5-Figure 9As shown, the plasma cutting equipment for processing electric tricycles described in the present invention includes a cutting machine body 1, a support structure 3 installed on the cutting machine body 1, a lifting structure 4 installed on the support structure 3, a driving structure 5 connected to the lifting structure 4, a moving structure 6 provided on the support structure 3, an adjusting structure 7 provided on the moving structure 6, and a telescopic structure 8 connected to the adjusting structure 7; the lifting structure 4 includes a mounting seat 401 and a hydraulic rod 402 rotatably connected to the mounting seat 401, the telescopic end of the hydraulic rod 402 is fixedly connected to a connecting piece 406, and both sides of the interior of the load-bearing frame 301 are A plurality of mounting brackets 403 are fixedly connected, and a rotating rod 404 is rotatably connected between the plurality of mounting brackets 403 located on the same side. Both ends of the two rotating rods 404 are rotatably connected to the load-bearing frame 301. The end of one of the rotating rods 404 is fixedly connected to a first swing arm 405, and the first swing arm 405 is rotatably connected to the connecting piece 406. At this time, the end of the hydraulic rod 402 rotates with the mounting seat 401, and the connecting piece 406 at the telescopic end rotates with the first swing arm 405 on the rotating rod 404. At the same time, the rotating rod 404 can be driven to rotate between the plurality of mounting brackets 403 through the first swing arm 405, and the rotating rod 404 drives the plurality of second The swing arm 407 rotates, and the position of the rotating rod 404 near the mounting frame 403 is fixedly connected to the second swing arm 407. The top of the second swing arm 407 is provided with an axis frame 408, and the axis frame 408 is rotatably connected to the second swing arm 407. A roller 409 is rotatably connected between the two symmetrical axis frames 408. At this time, since the rollers 409 and the second swing arms 407 at both ends form a parallelogram structure, the rollers 409 and the axis frames 408 at both ends are always in a horizontal state. Then, multiple rollers 409 need to be lifted upward to the maximum distance so that the metal plates can be quickly placed on the equipment through the rollers 409 to avoid the plates being placed. When the cutting machine 1 is moved, the rollers 409 are directly in contact with the sword fence 303, thereby avoiding the problem of scratching the bottom surface of the plate. It is only necessary to extend the telescopic end of the hydraulic rod 402 outward, thereby driving the multiple rollers 409 to push up to the maximum distance, so that the rollers 409 are higher than the sword fence 303, which is convenient for the subsequent metal plate to move from the end of the cutting machine body 1 to the center position, and avoids the problem of being blocked by the gantry during the placement of the metal plate. In addition, due to the rotational connection between the rollers 409 and the operating table, the friction between the rollers 409 and the metal plate is reduced, which facilitates the pushing of the metal plate to the specified position on the cutting machine body 1 and effectively avoids the surface of the metal plate from being scratched.

[0037] Specifically, such as Figure 1 and Figure 5-Figure 8As shown, a load-bearing frame 301 is fixedly connected to the cutting machine body 1, and the load-bearing frame 301 is installed on the cutting machine body 1 by bolts. Since a cover plate 302 is installed at the end of the load-bearing frame 301, it is convenient to inspect and repair the parts inside the load-bearing frame 301. A plurality of sword grids 303 are engaged on the load-bearing frame 301. Since a plurality of sword grids 303 are equidistantly installed on the load-bearing frame 301, the setting of the sword grids 303 can not only effectively disperse the pressure and improve the bearing capacity of the workbench, but also play a role in shock absorption.

[0038] Specifically, such as Figure 5 、 Figure 8 and Figure 9 As shown, one of the shaft frames 408 near the cover plate 302 is fixedly connected with a connecting frame 501, and one end of the connecting frame 501 near the motor 502 is in a "U" shape. The connecting frame 501 is rotatably connected to the outer wall of the second swing arm 407, and the output shaft of the motor 502 is fixedly connected to the adjacent roller 409. The roller 409 connected to its output shaft can be driven to rotate by the motor 502. Since a belt 504 is installed between the two adjacent rollers 409 through a pulley 503, the two rollers 409 can be rotated at the same time. The transmission drives multiple rollers 409 to rotate. At this time, multiple rollers 409 drive the plate to move to the center position of the load-bearing frame 301, and then the telescopic end of the hydraulic rod 402 is retracted inward to drive the rotating rod 404 to rotate in the opposite direction. At this time, multiple rollers 409 are driven by the second swing arm 407 to move horizontally in the direction away from the motor 502, and the height is reduced at the same time. The rollers 409 drive the plate to drop. When the height of the rollers 409 is lower than the height of the sword grid 303, the metal plate is carried between the multiple sword grids 303, and then the cutting is driven by the gantry. The cutting head cuts the plate to improve the cutting accuracy. Two pulleys 503 are fixedly connected to the two rollers 409 near the two ends, and four pulleys 503 are fixedly connected to the multiple rollers 409 near the center. A belt 504 is wrapped around two adjacent pulleys 503 on different rollers 409. A protective plate 505 is fixedly connected to one side of the load-bearing frame 301 near the belt 504. An "L"-shaped protective plate is installed on the side of the load-bearing frame 301 near the belt 504 by bolts. The guard plate 505 can shield the belt 504, so as to avoid the problem of sparks flying onto the belt 504 and breaking during the cutting process. After the adjustment of the distance between the telescopic plates 802 on both sides of the load-bearing frame 301 is completed, the plate needs to be moved from the end of the load-bearing frame 301 to the center position of the load-bearing frame 301. Since the motor 502 is fixed to the two ends of the shaft frame 408 through the connecting frame 501, the connecting frame 501 and the motor 502 always maintain a horizontal state, which improves stability and avoids the problem of the belt 504 falling off.

[0039] Specifically, such as Figure 5 、 Figure 6 、 Figures 9-11 As shown, both sides of the load-bearing frame 301 are fixedly connected with guide rails 601. The setting of the guide rails 601 facilitates the flexible adjustment of the lateral position of the clamp to adapt to plates of different lengths. The slide 602 is threadedly connected with a screw 603. During the rotation of the screw 603, the limit block 604 will no longer be pressed against the guide rail 601. The guide rail 601 is slidably connected with the limit block 604. The end of the screw 603 is rotatably connected to the limit block 604. The metal plate moves to the center of the load-bearing frame 301 through the roller 409. Before adjusting the position, it is necessary to adjust the position of the telescopic plates 802 on both sides of the load-bearing frame 301 to guide the plate, ensure that the plate moves to the center position of the equipment, improve the cutting accuracy of the plate, and improve the utilization rate of the plate. First, by rotating the screw 603 on the slide 602, since the screw 603 and the slide 602 are threadedly connected, and at this time the upper and lower ends of the limit block 604 are in conflict with the guide rail 601, it is convenient to slide the four slides 602 on the guide rails 601 on both sides to the four corners of the metal plate in turn.

[0040] Specifically, such as Figure 1 、 Figure 5 、 Figure 6 、 Figures 8-11As shown, the slide 602 is fixedly connected to the support frame 701, and the support frame 701 is rotatably connected to the first screw rod 703, and the top of the first screw rod 703 is provided with a driving hole 704. If there is an error between the spacing between the limit holes 807 and the thickness of the plate, it is only necessary to insert the hexagonal wrench into the driving hole 704 at the top of the guide rod 705 to drive the first screw rod 703 to rotate on the support frame 701. The first screw rod 703 can drive the slider 702 and the guide rod 705 to move up and down freely. At this time, the guide rod 705 can drive the pressure plate 706 to adjust the height up and down at will, which is convenient for solving the error problem and has strong flexibility. The slider 702 is threadedly connected to the first screw rod 703, and the upper surface of the slider 702 is fixedly connected to the guide rod 705. The top of the guide rod 705 is slidably connected to the support frame 701. When the first spring 707 is fixedly connected to the upper surface of the support frame 701, the first spring 707 is fixedly connected to the upper surface of the support frame 701. The pressure plate 706 stretches the first spring 707 downward. When the four slides 602 are slid to the appropriate position in turn according to actual conditions, the height of the pressure plate 706 needs to be adjusted according to the thickness of the plate to avoid the problem that the plate is difficult to be quickly placed between the two telescopic plates 802 due to the large height of the telescopic plate 802. By pulling the driving rod 803 outward until the end of the driving rod 803 no longer engages with the limit hole 807 on the guide rod 705, the height of the pressure plate 706 can be freely adjusted downward, and the pressure plate 706 can be pressed downward until the pressure plate 706 slides down to the appropriate distance. At this time, the metal plate is between the pressure plate 706 and the roller 409, thereby clamping and fixing the metal plate.

[0041] Specifically, such as Figure 5 、 Figure 6 、 Figure 8 、 Figure 10 and Figure 11As shown, one end of the pressure plate 706 is rotatably connected to the second screw rod 801, and the inner side of the pressure plate 706 is slidably connected to the telescopic plate 802, and the other end of the pressure plate 706 is slidably connected to the driving rod 803, and the docking block 806 is a hexagonal structure. The docking block 806 and the second screw rod 801 inside the pressure plate 706 are engaged with each other, and the docking block 806 and the groove opened on the second screw rod 801 are engaged with each other. The end of the driving rod 803 near the inner side is fixedly connected to the docking block 806, and the end of the driving rod 803 near the outer side is rotatably connected to the swivel 804, and the second tension spring 805 is fixedly connected between the swivel 804 and the outer wall of the pressure plate 706. To facilitate the resetting of the driving rod 803, and the rotating ring 804 can prevent the second tension spring 805 from being deformed, a plurality of limiting holes 807 are provided on the guide rod 705, and the driving rod 803 and the adjacent limiting holes 807 are engaged with each other. Then, it is necessary to adjust the spacing between the "L"-shaped telescopic plates 802 on both sides according to the width of the metal plate. It is only necessary to rotate the driving rod 803, and then the driving rod 803 also plays the function of driving the second screw rod 801 to rotate. At this time, by rotating the driving rod 803, the telescopic plate 802 can be driven to extend outward along the inner wall of the pressure plate 706 until the telescopic plates 802 on both sides are moved to the appropriate position. It is easy to operate, convenient for guiding metal plates of different widths, and has strong flexibility.

[0042] Specifically, such as Figure 2-Figure 4 As shown, the interior of the cutting machine body 1 is fixedly connected to two load-bearing beams 206, and a blanking plate 207 is fixedly connected between the load-bearing beam 206 and the inner wall of the cutting machine body 1. The cut parts or scraps slide into the storage box 205 through the blanking plate 207 inclined on the load-bearing beam 206, which is convenient for collecting and storing the parts or scraps. The bottom surface of the cutting machine body 1 is fixedly connected to two guide bars 201, and a guide plate 203 is slidably connected between the two guide columns 202. The setting of the two guide plates 203 guides the storage box 205, which facilitates the storage box 205 to slide quickly between the two guide bars 201, simplifying the operation process. , which improves the installation efficiency of the storage box 205. A spring 204 is fixedly connected between the inner side of the guide plate 203 and the guide bar 201. Three storage boxes 205 are clamped between the two guide bars 201. The three storage boxes 205 are clamped head to tail in turn, and then the storage box 205 at the end is aligned with the two guide plates 203 at the bottom of the cutting machine body 1, and the three storage boxes 205 are pushed inward. During the pushing process, the outer wall of the storage box 205 will resist the guide plates 203 on both sides, and drive the guide plates 203 to slide outward along the guide column 202, and compress the spring 204 until the three storage boxes 205 are completely clamped between the two guide bars 201.

[0043] When the present invention is in use, the ends of the three storage boxes 205 are engaged in sequence, and then the storage box 205 at the end is aligned with the two guide plates 203 at the bottom of the cutting machine body 1, and the three storage boxes 205 are pushed inward. During the pushing process, the outer wall of the storage box 205 will resist the guide plates 203 on both sides, and drive the guide plates 203 to slide outward along the guide posts 202, and compress the springs 204 until the three storage boxes 205 are completely engaged between the two guide bars 201, thereby facilitating the cut parts or scraps to slide into the storage box 205 through the blanking plate 207 inclinedly arranged on the load-bearing beam 206, making it convenient for the parts or scraps to be collected and stored. At the same time, the setting of the two guide plates 203 plays a guiding role for the storage box 205, making it convenient for the storage box 205 to slide quickly between the two guide bars 201, simplifying the operation process and improving the installation efficiency of the storage box 205;

[0044] Next, the load-bearing frame 301 needs to be installed on the cutting machine body 1 by bolts. Since a cover plate 302 is installed at the end of the load-bearing frame 301, it is convenient to inspect and repair the parts inside the load-bearing frame 301;

[0045] Then, it is necessary to lift the multiple rollers 409 upward to the maximum distance so that the metal sheet can be quickly placed on the equipment through the rollers 409 to avoid direct contact between the sheet and the sword grid 303 when placing the sheet, thereby avoiding the problem of scratching the bottom surface of the sheet. It is only necessary to extend the telescopic end of the hydraulic rod 402 outward. At this time, the end of the hydraulic rod 402 rotates with the mounting seat 401, and the connecting piece 406 at the telescopic end rotates with the first swing arm 405 on the rotating rod 404. At the same time, the rotating rod 404 can be driven to rotate between the multiple mounting frames 403 through the first swing arm 405, and the rotating rod 404 drives the multiple second swing arms 407 to rotate. At this time, since the supporting rollers 409 and the second swing arms 407 at both ends form a parallelogram structure, the supporting rollers 409 and the shaft frames 408 at both ends are always in a horizontal state, and the supporting rollers 409 are driven to push up to the maximum distance, so that the supporting rollers 409 are higher than the sword fence 303, which facilitates the subsequent movement of the metal sheet from the end of the cutting machine body 1 to the center position, and avoids the problem of being blocked by the gantry during the placement of the metal sheet and inconvenient operation. In addition, since the supporting rollers 409 are rotatably connected to the operating table, the friction between the supporting rollers 409 and the metal sheet is reduced, effectively preventing the surface of the metal sheet from being scratched.

[0046] After the rollers 409 are lifted upward, it is necessary to first adjust the positions of the telescopic plates 802 on both sides of the load-bearing frame 301 so as to guide the plate and ensure that the plate moves to the center position of the equipment, thereby improving the cutting accuracy of the plate and improving the utilization rate of the plate. First, by rotating the screw 603 on the slide 602, since the screw 603 is threadedly connected to the slide 602, and the upper and lower ends of the limit block 604 are in conflict with the guide rail 601 at this time, the limit block 604 will no longer be pressed against the guide rail 601 during the process of rotating the screw 603, thereby facilitating the sliding of the four slides 602 on the guide rails 601 on both sides to the four corners of the metal plate in turn. The setting of the guide rail 601 facilitates the flexible adjustment of the horizontal position of the clamp to adapt to plates of different lengths.

[0047] When the first screw rod 703 is rotated on the support frame 701, the first screw rod 703 can drive the slider 702 and the guide rod 705 to move freely up and down. At this time, the height of the pressing plate 706 can be freely adjusted up and down by the guide rod 705, which is convenient for solving the error problem and has strong flexibility.

[0048] The second spring 805 is fixedly connected to the second screw rod 801 by the rotating ring 804 rotating at the outer end of the driving rod 803 and the pressure plate 706, the second spring 805 facilitates the reset of the driving rod 803, and the rotating ring 804 can prevent the second spring 805 from being deformed. At this time, by rotating the driving rod 803, the telescopic plate 802 can be driven to extend outward along the inner wall of the pressure plate 706 until the telescopic plates 802 on both sides are moved to the appropriate position. The operation is simple, convenient for guiding metal plates of different widths, and has strong flexibility.

[0049] After completing the adjustment of the distance between the telescopic plates 802 on both sides of the load-bearing frame 301, it is necessary to translate the plate from the end of the load-bearing frame 301 to the center position of the load-bearing frame 301. At this time, the roller 409 connected to its output shaft can be driven by the motor 502 to rotate. Since a belt 504 is installed between two adjacent rollers 409 through a pulley 503, multiple rollers 409 can be driven to rotate at the same time. At this time, multiple rollers 409 drive the plate to move to the center position of the load-bearing frame 301, and then the telescopic end of the hydraulic rod 402 is retracted inward to drive the rotating rod 404 to rotate in the opposite direction. At this time, multiple rollers 409 are translated in the direction away from the motor 502 under the drive of the second swing arm 407, and the height is lowered at the same time. The roller 409 drives the plate to descend. When the height of the roller 409 is lower than the height of the sword grid 303, the metal plate is carried between multiple sword grids 303, and then the cutting head is driven by the gantry to cut the plate, which improves the cutting accuracy. In addition, since the motor 502 is fixed to the two ends of the shaft frame 408 through the connecting frame 501, the connecting frame 501 and the motor 502 always maintain a horizontal state, which improves stability and avoids the problem of the belt 504 falling off. At the same time, since the side of the load-bearing frame 301 close to the belt 504 is bolted with an "L"-shaped protective plate 505, the protective plate 505 can shield the belt 504, which can avoid the problem of sparks flying onto the belt 504 and causing it to break during the cutting process.
