A limiting component for limiting the anti-collision beam body 101 is provided on one side of the top of the base 301. The limiting component includes two end receiving units and a receiving displacement unit for driving the two end receiving units to move.

[0025] In one embodiment, the end receiving unit includes a sliding seat plate 309, with a receiving push rod 310 fixedly connected to the top of the sliding seat plate 309. An end support plate 311 is fixedly connected to the top of the receiving push rod 310, and an end limiting cover 312 is engaged with the top of the end support plate 311. The inner cavity shape of the end limiting cover 312 is consistent with the end shape of the anti-collision beam body 101.

When the shape of the anti-collision beam body 101 that needs to be limited changes, it can be matched and adapted by replacing the end limiting cover 312 with a different shape.

[0026] In one embodiment, in order to improve the stability of the crash beam body 101 during assembly, a plurality of middle receiving units are arranged between the two end receiving units, and the crash beam body 101 is placed and received by the middle receiving units.

The two clamping plates 3063 are both provided with a through slot at the end close to the overturning motor. The through slot is used to accommodate and limit the vehicle docking plate 203 during the clamping of the clamping plate 3063 on the energy absorption assembly 2, so as to further improve the clamping stability of the energy absorption assembly 2.

The output end of the adjusting motor is fixedly connected with a displacement screw rod 308. The middle part of the displacement screw rod 308 is threadedly connected with two movable blocks. The screw threads in the two movable blocks are opposite in direction. During the rotation of the displacement screw rod 308, the two movable blocks can be synchronously driven to move close to or away from each other. In this way, the positions of the two feeding displacement units can be adjusted, so that the energy absorption assembly 2 sent out can correspond to the position of the docking hole 317. The top of the two movable blocks is fixedly connected with the bottom of the two movable frames 304. The receiving displacement unit is consistent with the feeding displacement unit. The two movable blocks of the receiving displacement unit are respectively fixedly connected with the bottom of the two sliding seat plates 309.

The bottom of the two movable frames 304 is fixedly connected with limiting sliding blocks. The two limiting sliding blocks are in sliding connection with the inner wall of the limiting slot 316.

[0031] In use, the anti-collision beam body 101 is placed on the receiving plate 314 by using external lifting equipment. Then the receiving displacement unit is started to drive the two sliding seat plates 309 to move close to each other, thereby driving the two end seat plates to move close to each other, so as to limit the end of the anti-collision beam body 101. Then the two downward pressing rollers 315 are rotated to push the anti-collision beam body 101 to move downward, so that the bottom of the anti-collision beam body 101 is stably attached to the receiving plate 314, thereby completing the limiting of the anti-collision beam body 101. The state at this time is shown in Figure 8 ; The energy absorption assembly 2 is taken by the mechanical arm of the peripheral device or manually and placed in the mounting cylinder 3061, and the vehicle body docking plate 203 is placed between the two clamping plates 3063 and aligned with the through slot, and then the two clamping plates 3063 are driven by the two clamping push rods 3062 to move close to each other, so that the edge of the vehicle body docking plate 203 penetrates into the through slot, and then the friction pad 3064 is tightly abutted against the outer wall of the energy absorption box 201, thereby realizing clamping of the energy absorption assembly 2. Then the push guide rail 303 is started to drive the feeding frame 305 to move, thereby driving the clamping assembly 306 and the energy absorption assembly 2 to move as a whole to the direction of the anti-collision beam body 101, so that the docking clamping block 205 at one end of the docking rod 204 penetrates into the anti-collision beam body 101 through the docking hole 317, the installation cover is driven to rotate by starting the rotating motor, thereby driving the energy absorption assembly 2 to rotate as a whole, until the docking clamping block 205 is parallel to the docking groove 103, and then the push guide rail 303 continues to push, so that the docking clamping block 205 penetrates through the docking groove 103, and then the clamping assembly 306 is further driven by the turnover motor to turn over by 90 degrees, so that the length direction of the docking clamping block 205 is perpendicular to the docking groove 103; at this time, the push guide rail 303 keeps pushing the feeding frame 305, so that the beam body docking plate 202 of the energy absorption assembly 2 keeps abutting contact with the anti-collision beam body 101. At this time, the welding device of the peripheral device or manual operation is used to weld and fix the beam body docking plate 202 and the anti-collision beam body 101, thereby completing the assembly operation of the anti-collision beam assembly 1 as a whole, and the feeding frame 305 and the clamping assembly 306 are driven by the push guide rail 303 to reset as a whole.
