[0019] Reference Figures 1 to 4 , a symmetric beam-like structure combination device provided by an embodiment of the present application includes a base 20, a first end seat 30, and a second end seat 40. The first end seat 30 and the second end seat 40 are respectively located at both ends of the length direction of the base 20, wherein the first end seat 30 is located on the central axis of the base 20. At the same time, roller groups 31 are symmetrically arranged on both sides of the first end seat 30 to be able to roll and support the inner groove 112 of the workpiece 10, and the workpiece 10 can be supported at a certain height at the inner groove 112 of the workpiece 10. The second end seat 40 includes two positioning discs 41 and two pressing members 42. The two positioning discs 41 are perpendicular to the base 20 and are symmetrically distributed along the central axis of the base 20. At the same time, the two pressing members 42 are symmetrically arranged outside the two positioning discs 41 to be able to press the workpiece 10 from the outside after the retaining ring 111 of the workpiece 10 is sleeved on the two positioning discs 41. In this way, on the basis of supporting the workpiece 10 at the inner groove 112 through the roller groups 31, positioning is performed at the retaining ring 111 at the other end of the workpiece 10 by the positioning discs 41, and at the same time, the workpiece 10 is pressed by the pressing members 42, so that the workpiece 10 can be well fixed by combining the support, positioning, and pressing of the workpiece 10, which is convenient for quickly assembling and forming this symmetric beam-like structure. At the same time, the workpiece 10 is not likely to change again after being accurately fixed, and the assembling and forming quality can also be ensured.

[0020] In one embodiment, several workpiece support seats 21 are arranged on the top of the base 20 near the middle, such as four workpiece support seats 21. At the same time, several workpiece support seats 21 are arranged at intervals along the central axis of the base 20 and are symmetrically distributed with respect to the central axis. Thus, support can be formed at the bottom of the workpiece 10, which can ensure the consistency of the height of the workpiece 10, or in other words, ensure the levelness of the workpiece 10, and keep the workpiece 10 in a suspended state, facilitating the rapid and accurate assembly and forming of the workpiece 10.

[0021] In one embodiment, side limit seats 22 are symmetrically arranged on both sides of the workpiece support seats 21 on the top of the base 20. At the same time, the side limit seats 22 on the same side are close to the edge of the base 20 and are arranged in sequence along the extension direction of the central axis. The side limit seat 22 includes a support plate 221 and a limit pressing plate 222. Among them, the support plate 221 is vertically connected to the top of the base 20, and at the same time, the limit pressing plate 222 is vertically connected to the upper part of the support plate 221 and faces the central axis. Thus, the workpiece 10 can be limited on both sides by the limit pressing plate 222, which can further improve the stability of the workpiece 10, and then ensure the rapid assembly and forming of the workpiece 10 and ensure the forming quality of the workpiece 10.

[0022] Further preferably, the limit pressing plate 222 is connected to the support plate 221 through a connecting rod 223. One end of the connecting rod 223 away from the limit pressing plate 222 vertically penetrates the support plate 221 and is provided with a pull ring 224 to facilitate the pulling of the limit pressing plate 222 and flexibly adjust the pressing position of the limit pressing plate 222. At the same time, a plurality of positioning holes are uniformly arranged along the length direction of the connecting rod 223. Correspondingly, a positioning member 225 matching with the positioning holes is installed on the support plate 221. In this way, when limiting the workpiece 10 on the outside, the limit pressing plate 222 can be adjusted to an outer position first. After the workpiece 10 is placed in place, the limit pressing plate 222 is pushed inward through the pull ring 224 until it is tightly attached to the outer surface of the workpiece 10, and then the positioning member 225, such as a positioning pin, is inserted into the corresponding positioning hole to fix the limit pressing plate 222 on the support plate 221. In addition, when assembling workpieces 10 of different width specifications, the limit pressing plate 222 can also be applied, and only the limiting position of the limit pressing plate 222 needs to be adjusted, which is convenient to use.

[0023] In one embodiment, the pressing member 42 is sleeved on the central axis of the positioning disk 41, and at least three pressing plates 421 are uniformly arranged around the central axis. At the same time, a pressing nut 43 is sleeved on the outer end of the central axis in a threaded connection manner. Thus, the pressing member 42 can be pressed against the retaining ring 111 of the workpiece 10 by rotating the pressing nut 43, which is convenient for adjustment. The number of the pressing plates 421 can be three, four or six, and the specific number is not limited. At the same time, the pressing nut 43 can be a single nut or a double-nut form.

[0024] In one embodiment, a central positioning frame 23 is arranged at the top of the base 20 near the central position. The central positioning frame 23 includes a positioning bracket 231, a pressing shaft 232 and a fastening shaft 233. The positioning bracket 231 is located on the central axis of the base 20. The pressing shaft 232 is arranged on the upper part of the positioning bracket 231 and faces the central axis, and is used for pressing against the inner plate 113 of the workpiece 10 on the outside. The fastening shaft 232 is arranged at the top of the positioning bracket 231, on the side of the central axis away from the pressing shaft 232, and extends in the same direction as the pressing shaft 232, and is used for connecting the locking block 114 at the top of the workpiece 10. Thus, the workpiece 10 can be fixed at the top near the middle part, which can further ensure the stability of the workpiece 10 and facilitate the quick and accurate assembly and forming of the workpiece 10.
