[0021] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0022] Embodiment 1 like Figure 1-Figure 7 As shown, in this embodiment, a main beam force tube welding platform for an electric tricycle is provided, comprising a frame 1, on which a first fixing assembly 2 for horizontally fixing two vertical beams on both sides of the upper surface of the frame 1 and a plurality of second fixing assemblies 3 for evenly distributing a plurality of cross beams between the two vertical beams are provided, the plurality of cross beams are arranged in parallel, each cross beam is arranged perpendicularly to the two vertical beams, and the connection between the ends of the cross beams and the vertical beams is a welding position; Among them, the first fixed component 2 includes two movable seats 201, and the two movable seats 201 are symmetrically arranged on both sides of the upper surface of the frame 1, and the two movable seats 201 are provided with placement grooves 2011 for placing vertical beams; the two ends of the lower surface of the frame 1 are respectively slidably connected with a slide rod 202, and both ends of each slide rod 202 are fixed with guide columns 2021; the ends of the two movable seats 201 are provided with guide grooves 203, and the guide grooves 203 include a propulsion groove 2031, a transverse groove 2032 and a return groove 2033, and the transverse groove 2032 is arranged between the propulsion groove 2031 and the return groove 2033, and the ends of the propulsion groove 2031 and the return groove 2033 away from the transverse groove 2032 are inclined toward the middle of the frame 1, and the guide column 2021 is slidably connected in the corresponding guide groove 203.

[0023] like Figure 1 , Figure 5 and Figure 6 As shown, a motor 4 is fixedly mounted on the frame 1, and a screw rod 5 is arranged on the output shaft of the motor 4. The screw rod 5 is connected to the side wall of the frame 1 through the rotation of the motor 4, and the two ends of the screw rod 5 are respectively engaged with two slide bars 202. When the motor 4 drives the screw rod 5 to rotate, the screw rod 5 drives the two slide bars 202 to slide relative to or away from each other; During welding, the screw rod 5 is rotated to slide the slide bar 202, and the guide column 2021 is located at the end of the push groove 2031 away from the transverse groove 2032. In this state, the distance between the two movable seats 201 is the largest, which is conducive to placing the crossbeam on the second fixed component 3; The cross beam is placed on the second fixed component 3 and the vertical beam is placed in the placement groove 2011, and the motor 4 is started. The output shaft of the motor 4 drives the screw rod 5 to rotate, and the screw rod 5 leads the two slide bars 202 to slide relative to each other. In this way, the guide column 2021 slides toward the horizontal groove 2032 in the advancement groove 2031, prompting the two movable seats 201 to slide toward the middle of the frame 1. During the sliding process of the guide column 2021 in the advancement groove 2031, the end of the cross beam on the second fixed component 3 can be pushed. After the guide column 2021 slides to the inside of the horizontal groove 2032, the ends of multiple cross beams are automatically corrected to a flush state. As the guide column 2021 continues to slide, the guide column 2021 will slide from the horizontal groove 2032 to the inside of the return groove 2033. In this way, the two movable seats 201 will lead the two vertical beams to move away from each other. In this way, a gap will be generated between the side wall of the vertical beam and the end of the cross beam, and a welding gap between the vertical beam and the cross beam can be reserved.

[0024] Embodiment 2 like Figure 1-Figure 3 As shown, on the basis of embodiment 1, in order to be able to fix the vertical beam inside the placement groove 2011, the present embodiment is provided with a first clamping piece 6 on the movable seat 201, and the first clamping piece 6 includes a columnar sliding column 601, and the sliding column 601 is slidably connected to the side wall of the movable seat 201 through a first spring 602; the upper end of the sliding column 601 is fixedly connected to a connecting block 603, and a handle is fixed to the upper end surface of the connecting block 603; the side wall of the connecting block 603 is fixedly connected to a pressing plate 604 for pressing the vertical beam in the placement groove 2011.

[0025] like Figure 3 As shown, by pulling the connection block 603 upward with the handle, the sliding column 601 compresses the first spring 602 to slide upward, and at this time, the connection block 603 is rotated along the axis of the sliding column 601, and the pressing plate 604 can be removed from the inside of the placement groove 2011. At this time, the vertical beam can be conveniently placed in the inside of the placement groove 2011; When the vertical beam is placed in the placement groove 2011, the connection block 603 is lifted and rotated to cause the pressure plate 604 to rotate to the top of the vertical beam. At this time, the handle is released, and the spring pressure of the first spring 602 can enable the pressure plate 604 to press the vertical beam into the placement groove 2011.

[0026] like Figure 1 and Figure 3 As shown, in order to position the vertical beam in the length direction in the placement groove 2011, one end of the placement groove 2011 is slidably connected with a positioning block 7, and the end of the movable seat 201 close to the positioning block 7 is meshingly connected with an adjusting bolt 8, and the threaded end of the adjusting bolt 8 is rotatably connected to the side wall of the positioning block 7.

[0027] After placing the vertical beam inside the placement groove 2011, move the vertical beam so that one end of the vertical beam rests against the side wall of the positioning block 7, so that the vertical beam can be positioned in the length direction inside the placement groove 2011. Turn the adjusting bolt 8 to make the positioning block 7 slide inside the placement groove 2011 to adjust the position of one end of the vertical beam inside the placement groove 2011.

[0028] Embodiment 3 like Figure 1-Figure 7 As shown, based on the above embodiment, in this embodiment, the second fixing component 3 includes a base plate 301, and the base plate 301 is arranged on the frame 1; a plurality of bases 302 are evenly distributed on the upper surface of the base plate 301; and a support platform 303 for supporting the crossbeam is arranged on the upper part of the base 302.

[0029] A second clamping member 9 is provided on the base 302, and the second clamping member 9 includes a fixed clamping block 901, which is fixedly connected to the base 302 and located on one side of the support platform 303; an electric push rod 902 is fixedly installed on the base 302; a slider 903 is fixedly installed on the output shaft of the electric push rod 902; a movable clamping block 904 is slidably connected to the side wall of the slider 903 through a second spring 905, and the movable clamping block 904 is arranged opposite to the fixed clamping block 901; When placing the crossbeam, the electric push rod 902 is started, so that the output shaft of the electric push rod 902 drives the slider 903 to slide away from the fixed clamp block 901. At this time, the distance between the movable clamp block 904 and the fixed clamp block 901 becomes larger. In this state, the crossbeam is placed on the support platform 303 and close to the side wall of the fixed clamp block 901. Then the electric push rod 902 is operated. At this time, the electric push rod 902 drives the slider 903 to move toward the crossbeam, so that the movable clamp block 904 is pressed against the side wall of the crossbeam. At this time, the second spring 905 is in a compressed state. Under the cooperation of the movable clamp block 904 and the fixed clamp block 901, the crossbeam can be fixed on the support platform 303. In addition, due to the addition of the second spring 905, when a certain thrust is applied to the end of the beam, the beam can slide on the support platform 303. After the thrust disappears, the clamping force of the movable clamp block 904 and the fixed clamp block 901 fixes the beam.

[0030] The second clamping member 9 further includes a rotating plate 906, which is rotatably connected to the side wall of the slider 903, and a gear 9061 is provided on the rotating shaft of the rotating plate 906; a rack 907 is fixedly connected to the movable clamping block 904, and the rack 907 is meshedly connected with the gear 9061; wherein, an elastic arc plate 9062 is provided on the rotating plate 906; like Figure 4 and Figure 7As shown, in the natural state (i.e., the second spring 905 is not compressed), the rotating plate 906 is attached to the side wall of the slider 903. When the movable clamping block 904 compresses the second spring 905 and presses against the side wall of the beam, the movable clamping block 904 moves with the rack 907. At this time, the rack 907 drives the gear 9061 to rotate, that is, drives the rotating plate 906 to rotate, so that the end of the rotating plate 906 is pressed on the upper part of the beam, further increasing the stability of the beam on the support platform 303. When the rotating plate 906 presses the cross beam, the elastic arc plate 9062 produces a certain deformation, and when a certain thrust is applied to the end of the cross beam, it can also allow the cross beam to slide on the support platform 303; When the movable clamp block 904 is opened, the second spring 905 presses the movable clamp block 904 to return to its original position, and also returns the rotating plate 906 to its original position. Figure 4 The state shown is conducive to removing the beam from the support platform 303.

[0031] Two parallel guide rods 10 are provided on the frame 1, and the bottom plate 301 is slidably connected to the two guide rods 10, and the side wall of the bottom plate 301 is meshedly connected with a locking bolt 11, and the threaded end of the locking bolt 11 is movably pressed against the side wall of the frame 1. When the locking bolt 11 is loosened, the bottom plate 301 can slide on the frame 1 through the guide rod 10 to adjust the welding position of the horizontal beam relative to the vertical beam. After tightening the locking bolt 11, the adjusted bottom plate 301 can be fixed to improve the adjustability of welding.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
