[0021] The workpiece alignment auxiliary device provided by the utility model is designed to realize the alignment of the U-rib plate unit and the leveling device, but is not only suitable for the alignment of the U-rib plate unit and the leveling device, but also suitable for the alignment of other workpieces and other devices along the horizontal direction.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and an embodiment of the present invention.

[0023] See also Figures 3 to 9 In one embodiment of the utility model, the workpiece alignment auxiliary device of the utility model includes a support frame 1, a fixed stop block 2, a movable stop block 3 and a driving mechanism 4. The upper surface of the support frame 1 is used to support the workpiece. The fixed stop block 2 and the driving mechanism 4 are fixed on the support frame 1. The fixed stop block 2 and the movable stop block 3 protrude from the upper surface of the support frame 1. The movable stop block 3 can move relative to the support frame 1 along the direction of the line connecting it and the fixed stop block 2. The power output rod of the driving mechanism 4 is connected to the movable stop block 3, which is used to drive the movable stop block 3 to move relative to the support frame 1.

[0024] The workpiece is placed on the support frame 1, between the fixed stopper 2 and the movable stopper 3. When the movable stopper 3 moves toward the fixed stopper 2, the workpiece is pushed toward the fixed stopper 2 until the workpiece is close to the fixed stopper 2. The workpiece is aligned by limiting the position of the fixed stopper 2. When the workpiece needs to be aligned to a different position, the position of the fixed stopper 2 can be changed accordingly.

[0025] In order to adjust the position of the fixed stopper 2 and meet various requirements, a plurality of fixing parts 11 are provided on the support frame 1 along the connecting line direction of the fixed stopper 2 and the movable stopper 3. The fixed stopper 2 is fixedly connected to the support frame 1 through the fixing parts 11. After the fixing between the fixed stopper 2 and the support frame 1 is released, the fixed stopper 2 can move relative to the support frame 1 along the connecting line direction between the fixed stopper 2 and the movable stopper 3. In other embodiments of the utility model, if only one size of workpiece needs to be adapted, the position of the fixed stopper 2 relative to the support frame 1 can also be designed to be non-adjustable.

[0026] The multiple fixing parts 11 are provided to achieve discrete adjustment of the position of the fixed stopper 2, and the precision is not high. In order to further improve the adjustment precision, the fixed stopper 2 is fixedly connected to the support frame 1 through the connecting block 5, and the connecting block 5 is fixedly connected to the support frame 1 through the fixing part 11, and the distance of the fixed stopper 2 relative to the connecting block 5 along the connecting direction of the fixed stopper 2 and the movable stopper 3 is continuously adjustable.

[0027] In order to achieve continuous adjustment of the distance between the fixed stopper 2 and the connecting block 5, the connecting block 5 is connected to the fixed stopper 2 by means of an adjusting bolt 51, which is arranged along the connecting line between the fixed stopper 2 and the movable stopper 3, and passes through an adjusting nut 52, a light hole on the connecting block 5 and another adjusting nut 52 in sequence, and is threadedly connected to the fixed stopper 2. The adjusting bolt 51 is threadedly connected to the adjusting nut 52, and the distance between the fixed stopper 2 and the connecting block 5 is adjusted by screwing the adjusting nut 52. After the adjustment is completed, the adjusting nuts 52 on both sides of the connecting block 5 are tightened. In other embodiments of the utility model, the continuous adjustment of the distance between the fixed stopper 2 and the connecting block 5 can also be achieved by means of other structures.

[0028] The fixing part 11 of this embodiment is a through hole opened on the support frame 1, and a clearance hole 53 is correspondingly provided on the connecting block 5. The bolt passes through the clearance hole 53 and the fixing part 11 and is connected with the nut to achieve the fixation between the connecting block 5 and the support frame 1. In this embodiment, four clearance holes 53 are provided on the connecting block 5, two on one side, which can ensure the stability of the connection between the connecting block 5 and the support frame 1. In other embodiments of the utility model, the fixing part 11 can also be other structures, which can achieve multi-level adjustment of the fixed stopper 2 relative to the support frame 1 along the direction of the connection line between it and the movable stopper 3.

[0029] The support frame 1 is provided with a track 12 along the connecting direction of the fixed stopper 2 and the movable stopper 3. The two tracks 12 are arranged opposite to each other. The movable stopper 3 is provided with two first rollers S corresponding to the two tracks 12, respectively, so that the movable stopper 3 can move relative to the support frame 1 under the guidance of the track 12. In this embodiment, four first rollers S are also provided on the fixed stopper 2. The track 12 is divided into two sections, one section is used to accommodate and guide the first rollers S of the movable stopper 3, and the other section is used to accommodate and guide the first rollers S of the fixed stopper 2. The first rollers S can reduce the resistance of the fixed stopper 2 and the movable stopper 3 to move relative to the support frame 1, and the resistance is smaller than the mode in which the slider cooperates with the slide rail. The block is provided with two first rollers S on one side, a total of four first rollers S, which can ensure the stability of the block movement.

[0030] The upper ends of the fixed stopper 2 and the movable stopper 3 protrude toward each other, respectively forming a roller mounting seat, on which a second roller Q is arranged, and the axis of the second roller Q is arranged perpendicular to the upper surface of the support frame 1. Fig.10The workpiece alignment auxiliary device is used to realize the alignment between the U-rib plate unit 100 and the leveling device 200. The conveying device 300 conveys the U-rib plate unit 100 along the first direction d1, and the leveling device 200 corrects the U-rib plate unit 100 section by section. The U-rib plate unit 100 has a large span along the first direction d1. A plurality of conveying devices 300 and workpiece alignment auxiliary devices are arranged at intervals along the first direction d1. The workpiece alignment auxiliary device is used to adjust the position of the U-rib plate unit 100 relative to the leveling device 200 along the second direction d2. Therefore, the connecting direction of the fixed stopper 2 and the movable stopper 3 is parallel to the second direction d2. When the conveying device 300 conveys the U-rib plate unit 100, the U-rib plate unit 100 is first lifted to separate the U-rib plate unit 100 from the upper surface of the support frame 1 to reduce friction resistance and damage. After lifting, the U-rib plate unit 100 is conveyed forward. To avoid hindering the conveying process, the driving mechanism 4 needs to reset the movable block 3 before lifting. During the conveying process, if the U-rib plate unit 100 deflects, the fixed block 2 and the movable block 3 can limit the amplitude of the deflection of the U-rib plate unit 100, and the second roller Q can reduce the friction resistance and damage between the workpiece alignment auxiliary device and the U-rib plate unit 100. In other embodiments of the utility model, if the workpiece does not need to be conveyed along the first direction d1, the roller mounting seat and the second roller Q may not be provided.
