The square columns 209 are movably clamped into the inside of the square grooves 210.

[0026] Through the cooperation of the lifting structure 2 and the adjusting structure 3, when the device is in use, several driven gears 203 can be lifted upward by the pneumatic telescopic cylinder 201, so that the lifted driven gears 203 are disengaged from the driving gear 104. At this time, when the driving gear 104 rotates, it will not drive the lifted driven gears 203 to rotate, so that the height of the unidirectional clamping mechanism 4 can be adjusted. Furthermore, the device can be adapted to clamp the special-shaped frame reinforcement 5, and the guide rail plate 303 is driven to move by the electric push rod 302, so that the device can be adapted to clamp the frame reinforcement 5 with different inner diameter sizes for use.

[0027] The adjusting structure 3 includes a lead screw movable sleeve 301, an electric push rod 302, a guide rail plate 303, a positioning table 304, a guide rod 305 and a guide rail groove 306. The outer surfaces of the lifting lead screws 204 are all movably installed with lead screw movable sleeves 301. Electric push rods 302 are fixedly installed on the outer sides of the lead screw movable sleeves 301. The output ends of the electric push rods 302 are fixedly connected with guide rail plates 303. Positioning tables 304 are fixedly installed at the central positions on the outer sides of the guide rail plates 303. Guide rods 305 are movably installed inside the positioning tables 304. The guide rods 305 all movably penetrate through the inside of the positioning tables 304. Two guide rail grooves 306 are provided on both sides of the surface of the guide rail plate 303.

[0028] The sliding plates 402 are all slidably inserted into the inside of the guide rail grooves 306, and the lead screw movable sleeves 301 are all slidably inserted into the inside of the lifting grooves 106.

[0029] The driving gear 104 is meshed and connected with four driven gears 203. A plurality of balls are provided on the outer surfaces of the L-shaped movable plates 206 located on the inner sides of the L-shaped movable ring grooves 205.

[0030] The tooth surfaces of the driving gear 104 and the driven gears 203 are all provided with inclined surfaces, and the bottom ends of the guide rods 305 are all slidably inserted into the inside of the sliding grooves 107.

[0031] When the new energy vehicle frame reinforcement welding anti-misalignment device is in use, first place the frame reinforcement 5 on the surface of the base 101, and make the mounting frame 105 pass through the central position on the surface of the frame reinforcement 5, so that the center of the frame reinforcement 5 is close to the axis position of the central rotating rod 103; When the heights of the four sides of the frame reinforcement 5 are the same, the central rotating rod 103 can be directly driven to rotate by the servo motor 102, so as to drive the driving gear 104 to rotate, and the driving gear 104 drives the four driven gears 203 to rotate simultaneously. At this time, the rotation of the driven gears 203 will drive the lead screw movable sleeves 301 to lift on their surfaces, so as to adjust the height of the lead screw movable sleeves 301 to adapt to the height position of the frame reinforcement 5; When the frame reinforcement 5 has a special-shaped structure with inconsistent heights on all four sides, three of the driven gears 203 can be lifted upward first by the pneumatic telescopic cylinder 201. At this time, the L-shaped movable plate 206 is inserted inside the L-shaped movable ring groove 205, which will drive the driven gear 203 to move upward, thus disengaging the meshing between the driven gear 203 and the driving gear 104. When the servo motor 102 drives the central rotating rod 103 to rotate at this time, the driving gear 104 will only drive the non-moved driven gear 203 to rotate, so that the lead screw movable sleeve 301 connected to the rotatable driven gear 203 is adjusted to the required height position. Subsequently, the adjusted driven gear 203 is lifted upward so that it no longer meshes with the driving gear 104, and one of the lifted driven gears 203 is lowered. Repeat the above operations until all four lead screw movable sleeves 301 are adjusted to the appropriate height positions; After the height of the lead screw movable sleeve 301 is adjusted, the output end is pushed out by the electric push rod 302, so that the guide rail plate 303 drives the positioning table 304 to move, so that the guide rod 305 moves inside the sliding groove 107, and then the distance between the clamping mechanism 4 and the outer side of the frame reinforcement 5 is adjusted to adapt to the positions of frame reinforcements 5 of different sizes; Subsequently, the reduction motor 401 drives the forward rotating shaft 403 to rotate, so that the forward rotating shaft 403 drives the first clamping plate 404 to rotate forward, and at the same time drives the bevel gear 414 to rotate through the reverse gear 413, and drives the reverse gear 413 on the surface of the reverse rotating shaft 410 to rotate through the bevel gear 414, so that the reverse rotating shaft 410 rotates in the reverse direction, so that the first clamping plate 404 and the second clamping plate 405 both rotate toward the outer side position of the frame reinforcement 5 at the same time, so as to clamp the frame reinforcement 5 between the first clamping plate 404 and the second clamping plate 405; At this time, the position of the sliding plate 402 can be moved on the surface of the guide rail plate 303, so as to adjust the positions of the first clamping plate 404 and the second clamping plate 405, align the waist-shaped hole 407 with one of the threaded holes 6 on the surface of the frame reinforcement 5, and insert the limit pin 408 through the inside of the waist-shaped hole 407 and into the inside of the threaded hole 6 at the same time to position and fix the frame reinforcement 5, so as to avoid the situation of the frame reinforcement 5 shifting.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
