DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will describe the present utility model in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-4 shown, the utility model provides a flexible positioning, conveying and displacement device for structural parts, including: a fixed conveying frame 1, a conveying positioning support 2, and a pneumatic displacement device 3. Among them:

[0020] A rotatable conveying positioning support 2 is installed on the fixed conveying frame 1, and a pneumatic displacement device 3 for pushing the conveying positioning support 2 is installed on one side of the conveying positioning support 2; a plurality of groups of conveying rollers 21 are arranged on the conveying positioning support 2, and a flexible fixing platform 23 for fixing structural parts is fixedly installed below the conveying rollers 21.

[0021] Specifically, the conveying and positioning bracket 2 includes: a rotating frame 22 rotatably mounted on the fixed conveying frame 1. A plurality of groups of conveying rollers 21 with uniform spacing are uniformly mounted on the rotating frame 22. The top surfaces of the plurality of groups of conveying rollers 21 form a conveying surface, and the flexible fixing platform 23 is fixed below the conveying surface. Preferably, fixed bottom frames 13 are installed on both sides of the fixed conveying frame 1. Two groups of guiding conveying rollers 11 are arranged on the fixed bottom frames 13. The two groups of guiding conveying rollers 11 are respectively arranged at both ends of the conveying and positioning bracket 2, and the conveying surfaces of the guiding conveying rollers 11 and the conveying rollers 21 are at the same horizontal height. Structural members can be conveyed through the conveying rollers 11 and the conveying rollers 21.

[0022] Exemplarily, a plurality of positioning holes 231 for installing accessories are uniformly arranged on the flexible fixing platform 23. The flexible fixing platform 23 is located below the conveying surface of the conveying rollers 21. There are multiple groups of uniformly distributed positioning holes 231 on the flexible fixing platform 23. The structural members are fixed by accessories that can be installed in the positioning holes 231. The flexible fixing platform 23 is processed by grinding, with precise dimensions. The pitch of the positioning holes 231 is equal, and the hole diameters are the same. It is processed by a machining center, providing precise positioning for the installation and fixation of the accessories. The installation accessories are installed in different positioning holes 231 to adapt to the positioning and clamping requirements of different structural members.

[0023] In the present utility model, a left rotating shaft 24 and a right rotating shaft 25 are respectively installed on both sides of the rotating frame 22. The left rotating shaft 24 and the right rotating shaft 25 are installed on the fixed conveying frame 1 through bearing seats 12.

[0024] The pneumatic displacement device 3 includes: a cylinder 31. The fixed end of the cylinder 31 is fixedly installed on the fixed conveying frame 1 through a cylinder mounting seat 33.

[0026] During work, when the cylinder 31 retracts, the conveying surfaces of the conveying rollers 21 installed on the rotating frame 22 and the conveying rollers 11 installed on the fixed bottom frames 13 are on the same horizontal plane. The structural members enter above the flexible fixing platform 23 through the conveying surface. At the same time, the structural members are fixed by accessories that can be installed in the positioning holes 231. After the structural members are fixed, they can be welded in the horizontal position. At the same time, after welding is completed, the cylinder 31 extends, pushing the conveying and positioning bracket 2 to rotate and displace. After displacement, the structural members can be welded in the vertical position. After welding is completed, the cylinder 31 retracts, releasing the fixed accessories, and the structural members enter the next working station through the conveying rollers.
