The positioning component 5 can lift the baffle 7 while pushing the steel structure to move on the placement platform 2, so that the steel structure contacts the baffle 7. When the baffle 7 is lifted or lowered, the baffle 7 moves on the limit T-pillar 6, and the limit T-pillar 6 limits the baffle 7, so that the baffle 7 can only move up and down; The positioning assembly 5 includes an ejection mechanism 56 , and a pushing mechanism 57 is provided on the right side of the ejection mechanism 56 ; In the above structure, through the setting of the ejection mechanism 56, when the ejection mechanism 56 moves to the left, the ejection mechanism 56 can push the baffle 7 upward so that the top of the baffle 7 is not flush with the top of the placement platform 2. At this time, the steel structure on the placement platform 2 can contact the baffle 7. When the ejection mechanism 56 moves, the pushing mechanism 57 also moves to the left. At this time, the pushing mechanism 57 can push the steel structure on the placement platform 2 toward the baffle 7, so that the steel structure can contact the baffle 7. The pushing mechanism 57 includes a fixed bracket 5701, a connecting plate 5702 is installed on the outer edge of the fixed bracket 5701, a front sleeve 5703 and a rear sleeve 5715 are installed on the inner wall of the connecting plate 5702, a front screw rod 5704 and a rear screw rod 5716 are installed on the inner walls of the front sleeve 5703 and the rear sleeve 5715 respectively, and the outer edges of the front screw rod 5704 and the rear screw rod 5716 are respectively threadedly connected to the front moving cylinder 5705 and the rear moving cylinder 5717.

Gradually, the front contact piece 5710 and the rear contact piece 5722 on the front sleeve 5703 and the rear sleeve 5715 come into contact with the steel structure on the placement platform 2, pushing the steel structure toward the baffle 7 so that the steel structure comes into contact with the baffle 7. At this time, the front support spring 5713 and the rear support spring 5725 are both squeezed, and the front support spring 5713 and the rear support spring 5725 are squeezed. The elastic force of the spring 5713 and the rear support spring 5725 supports the front circle 5708 and the rear circle 5720 respectively, so that the front contact piece 5710 and the rear contact piece 5722 on the front circle 5708 and the rear circle 5720 can fully contact the steel structure. The elastic force of the front support spring 5713 and the rear support spring 5725 clamps the steel structure so that the steel structure cannot move, thereby improving the flexibility and diversity of use of the device.

When the length of the steel structure at the rear sleeve 5715 end is longer than the length of the steel structure at the front sleeve 5703 end, the front support spring 5713 on the rear sleeve 5715 is compressed first, and then the front support spring 5713 on the front sleeve 5703 is compressed again, so that the device can position and clamp two steel structures of different lengths, further improving the flexibility of the device.

At this time, the top of the baffle 7 and the top of the placement platform 2 are no longer on the same plane, so that the baffle 7 can block the steel structure on the placement platform 2. When the top of the baffle 7 and the top of the placement platform 2 are on the same plane, they are in the loading state. At this time, the steel structure can be placed on the placement platform 2, and then the steel structure can be pushed into the space formed by the positioning pins 4.

When the height of the flat plate 5604 becomes higher, the distance between the top of the baffle 7 and the top of the placement platform 2 can be increased, so that the baffle 7 can contact the higher steel structure. When the top of the steel structure is longer than the bottom of the steel structure, the baffle 7 needs to be raised so that the top of the steel structure contacts the baffle 7, thereby improving the flexibility of the device.

[0033] Working principle: When in use, place the steel structure in the positioning pin 4 that determines the spatial position. At this time, the steel structure is located in the middle position of the placement platform 2. The head screw 53, the middle connecting rod 54 and the tail screw 55 are driven to rotate by the reduction servo motor 52. When the head screw 53 and the tail screw 55 rotate, they will respectively drive the mobile bracket 5601 and the fixed bracket 5701 to move to the left. When the mobile bracket 5601 moves to the left, it will drive the bottom bracket 5602 and the inclined plate 5603 The inclined plate 5603 is tilted to move with the flat plate 5604. Since the inclined plate 5603 is tilted, the inclined plate 5603 can gradually push the roller 9, the bracket 8 and the baffle 7 upward, so that the top of the baffle 7 is not on the same plane as the top of the placement platform 2. When the height of the baffle 7 needs to be increased, the flat plate 5604 is pushed upward by rotating the screw 5607. When the screw 5607 rotates, it drives the internal thread block 5608 to move to the left. When the baffle 7 is pushed out, the bracket 5701 and the connecting plate 5701 are fixed. 02. The front sleeve 5703 and the rear sleeve 5715 also move to the left, and gradually the front contact piece 5710 on the front sleeve 5703 contacts the steel structure, the front end steel structure is pushed, and gradually the front end steel structure contacts the baffle 7. At this time, the front support spring 5713 is compressed by the front circle 5708, and the front circle 5708 is supported by the elastic force of the front support spring 5713, so that the front end steel structure can be clamped, and the rear contact piece 5722 on the rear sleeve 5715 contacts the steel structure, and the rear end steel structure The structure is pushed, and gradually the rear end steel structure contacts the baffle 7. At this time, the rear support spring 5725 is compressed by the rear left baffle 5718, and the rear end steel structure is clamped by the elastic force of the rear support spring 5725, so that the front and rear end steel structures can be positioned. When the automatic positioning function is not needed, the front moving cylinder 5705, the front circle 5708, the front connecting bracket 5709 and the front contact piece 5710 are driven to move by rotating the front screw rod 5704, and gradually contact and clamp the steel structure.
