Technical Field
[0001] This utility model relates to the field of turnover box production technology, specifically to a turnover box gripper. Background Technology
[0002] Turnover boxes are widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. They are resistant to acids and alkalis, oil stains, and are non-toxic and odorless. They can be used to hold food, are easy to clean, facilitate the turnover of parts, are neatly stacked, and are easy to manage. During the production process of turnover boxes, robotic arms drive grippers to pick them up and move them to the next production line. Patent publication number CN211768848U discloses a gripper for a turnover box, including a frame and a gripping mechanism mounted on the frame. The frame is rectangular, and the gripping mechanism has hooks at both ends of the frame. The hooks are symmetrically arranged, and their shapes match the handles of the turnover box. The spacing between the hooks corresponds to the size of the turnover box. Each hook is hinged to the frame and is driven to rotate by a gripping cylinder. The gripping mechanism has a pressure block below the frame, which is driven to move vertically by a pressing cylinder. When working, the hooks can clamp onto the handles of the turnover box, and the pressure block applies force in three directions to fix the turnover box, ensuring safe and stable transfer.
[0003] The shortcomings of existing turnover box grippers are that the hooks are fixedly installed on the drive shaft and cannot be adjusted according to the size of the turnover box, thus they cannot grip turnover boxes of different sizes. Therefore, a turnover box gripper is proposed, in which the moving connecting column can adjust the position of the side plate so that the pressure plate can clamp turnover boxes of different sizes. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a turnover box gripper. The movable connecting column can adjust the position of the side plate, so that the pressure plate can clamp turnover boxes of different sizes.
[0005] The technical solution adopted by this utility model to solve its technical problem is a turnover box gripper, including a structural frame and a side plate. The structural frame is provided with connecting columns at equal intervals at both ends. The side plate is fixed between the connecting columns by bolts. A cylinder is installed through a mounting bracket on one side of the side plate. A pressure plate is fixed to the output shaft of the cylinder by bolts. An anti-detachment component is provided on one side of the pressure plate. The anti-detachment component includes a small cylinder mounted on one side of the pressure plate via a mounting bracket. The output shaft of the small cylinder located on the other side of the pressure plate is connected to a locking block via a threaded groove.
[0006] By adopting the above technical solution, the cylinder pushes the pressure plate to move and clamp the turnover box. The small cylinder pushes the locking block to extend and lock the turnover box clamped by the pressure plate to prevent it from falling off between the pressure plates. The movable connecting column can adjust the position of the side plate and the pressure plate, which is convenient for clamping and grabbing turnover boxes of different sizes.
[0007] Specifically, the top of the connecting column is provided with a slot, and the top of the structural frame is connected with fixing bolts corresponding to the slot through threaded grooves at equal intervals.
[0008] Specifically, a mounting block is welded to the top of the structural frame.
[0009] Specifically, anti-slip strips are welded at equal intervals on the side of the pressure plate away from the side plate, and a reserved groove is opened at one end of the pressure plate, with the locking block located inside the reserved groove.
[0010] Specifically, an auxiliary rod is connected to the side of the pressure plate away from the anti-slip strip via a threaded groove, and the auxiliary rod passes through the side plate.
[0011] Specifically, a support rod is fixed between the side plate and the connecting column by bolts.
[0012] The beneficial effects of this utility model are: The present invention describes a turnover box gripper, in which the connecting column is sleeved at both ends of the structural frame and can be extended and retracted. The position of the side plate and pressure plate can be adjusted to facilitate clamping turnover boxes of different sizes. Tightening the fixing bolts so that its bottom end is inserted into the corresponding slot can fix the connecting column after it has been moved.
[0013] The present invention describes a turnover box gripper, in which a cylinder pushes a pressure plate to move, which can clamp the turnover box. A small cylinder pushes a locking block to extend, which can lock the turnover box held by the pressure plate and prevent it from falling off between the pressure plates. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] The movable connecting column allows adjustment of the side plate position, enabling the pressure plate to hold turnover boxes of different sizes, such as... Figure 1-3 As shown, the present invention provides a turnover box gripper, which includes a structural frame 1 and a side plate 3. The structural frame 1 is provided with connecting columns 2 at equal intervals at both ends. The side plate 3 is fixed between the connecting columns 2 by bolts. A cylinder 4 is installed through one side of the side plate 3 by a mounting bracket. A pressure plate 5 is fixed to the output shaft of one side of the cylinder 4 by bolts. An anti-detachment component 6 is provided on one side of the pressure plate 5. The anti-detachment component 6 includes a small cylinder 601 mounted on one side of the pressure plate 5 via a mounting bracket. The output shaft of the small cylinder 601 located on the other side of the pressure plate 5 is connected to a locking block 602 via a threaded groove.
[0018] When in use, cylinder 4 pushes pressure plate 5 to move and clamp the turnover box. Small cylinder 601 pushes the locking block 602 to extend and lock the turnover box clamped by pressure plate 5 to prevent it from falling off between pressure plates 5. The movable connecting column 2 can adjust the position of side plate 3 and pressure plate 5 to facilitate clamping and grabbing turnover boxes of different sizes.
[0019] For example, such as Figure 2 As shown, the present invention also includes a slot 9 on the top of the connecting column 2, and fixing bolts 8 corresponding to the slot 9 are equidistantly connected to the top of the structural frame 1 through threaded grooves.
[0020] When in use, tighten the fixing bolt 8 so that its bottom end is inserted into the corresponding slot 9 to fix the moving connecting column 2.
[0021] For example, such as Figure 1 As shown, the present invention also includes a mounting block 7 welded to the top of the structural frame 1.
[0022] When in use, the mounting block 7 facilitates the installation of this device on an external robotic arm.
[0023] For example, such as Figure 3 As shown, the present invention also includes anti-slip strips 10 welded at equal intervals on the side of the pressure plate 5 away from the side plate 3, and a reserved groove 11 opened at one end of the pressure plate 5, with the locking block 602 located inside the reserved groove 11.
[0024] When in use, the anti-slip strip 10 can improve the anti-slip ability of the pressure plate 5, and the opening of the reserved groove 11 facilitates the entry of the card block 602.
[0025] For example, such as Figure 3 As shown, the present invention also includes an auxiliary rod 12 connected to the side of the pressure plate 5 away from the anti-slip strip 10 through a threaded groove, and the auxiliary rod 12 passes through the side plate 3.
[0026] When in use, the auxiliary rod 12 can improve the structural stability of the pressure plate 5 without affecting its movement.
[0027] For example, such as Figure 1 As shown, the present invention also includes a support rod 13 that is bolted between the side plate 3 and the connecting column 2.
[0028] When in use, the support plate 13 can improve the connection between the side plate 3 and the connecting column 2.
[0029] In use, personnel use bolts to install the device onto an external robotic arm via mounting block 7, and use air pipes to connect cylinder 4 and small cylinder 601 to an external air supply device. An external robotic arm drives the device to move, causing the pressure plate 5 to move to both sides of the turnover box. The cylinder 4 is opened to push the pressure plate 5 to move and clamp the turnover box. Anti-slip strips 10 are equidistantly arranged on one side of the pressure plate 5, which can play an anti-slip role and prevent the clamped turnover box from sliding. When the pressure plate 5 clamps the turnover box, the personnel open the small cylinder 601 to push the locking block 602 out, which can lock the turnover box clamped by the pressure plate 5 to prevent the turnover box from falling off between the pressure plates 5. When the small cylinder 601 is not working, the locking block 602 is located in the reserved slot 11 and will not affect the clamping of the turnover box by the pressure plate 5. The connecting column 2 is sleeved on both ends of the structural frame 1. It can be extended and retracted, and the position of the side plate 3 and the pressure plate 5 can be adjusted to hold turnover boxes of different sizes. Tightening the fixing bolt 8 so that its bottom end is inserted into the corresponding slot 9 can fix the moving connecting column 2.
