Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stacking technology, and in particular relates to a centering positioning tool for a stacker machine. Background Technology
[0002] After processing, goods need to be stacked before transportation or storage. Stacking equipment is usually used for stacking. Stacking equipment that uses robotic arms to perform the grasping action operates smoothly, with high precision, short cycle time, and a high degree of automation during the stacking process.
[0003] Stacking equipment is usually equipped with conveyor systems upstream, which transfer goods to the gripping position. Then, a robotic arm grips and stacks the goods. The neatness of the goods when they arrive at the gripping position has a decisive impact on the neatness of the subsequent stacking. Therefore, a centering positioning fixture for stacking cranes is needed to center the goods at the gripping position, so that the goods are in the center during gripping, thereby ensuring that the goods maintain good neatness after stacking. Utility Model Content
[0004] The purpose of this utility model is to provide a centering positioning fixture for a stacker crane, which centers the goods at the gripping position so that the goods are in the center during gripping, thereby ensuring that the goods after stacking maintain good regularity, thus solving the technical problems mentioned in the background art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A centering positioning fixture for a stacker crane includes a platform: two symmetrically arranged cylinders are fixedly installed at the bottom of the platform by bolts, the output end of the cylinders is fixedly connected to a base plate by a flange, a clamping plate one and a clamping plate two are slidably connected to the top of the base plate, a plate groove adapted to the clamping plate one and the clamping plate two is opened at the top of the platform, a motor is fixedly installed at the bottom of the platform by bolts, a rotating rod is fixedly connected to the output shaft of the motor by a flange, a support rod is rotatably connected to the surface of the rotating rod by a rotating shaft, and a cargo plate is placed on the top of the platform.
[0006] Preferably, a pad is adhered to the surface of the second clamping plate, and the pad is a rubber pad.
[0007] Preferably, both clamping plate one and clamping plate two are rotatably connected to the support rod via a rotating shaft.
[0008] Preferably, the bottom of both the first clamping plate and the second clamping plate are integrally formed with sliders, and the top of the base plate is provided with a groove that matches the sliders.
[0009] Preferably, the outer side of the platform is provided with a stacking device and a conveying device.
[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model uses a motor to drive the rotating rod to rotate, which in turn drives the clamping plate one and clamping plate two to move through the support rod. This allows the clamping plate one and clamping plate two to center the position of the cargo plate, thus achieving the goal of centering the cargo at the gripping position. This ensures that the cargo is in the center during gripping, thereby ensuring that the stacked cargo maintains good regularity.
[0012] 2. This utility model protects the surface of the second clamping plate by setting a protective pad, thus preventing the cargo plate from being damaged by bumps when it comes into direct contact with the second clamping plate;
[0013] 3. This utility model limits the movement of clamping plate one and clamping plate two by using the combination of slider and groove, thus preventing clamping plate one and clamping plate two from shaking during movement. Attached Figure Description

[0020] In the following description, embodiments of the stacker crane centering fixture of the present invention will be described with reference to the accompanying drawings.
[0021] Example 1:
[0022] Figure 1-3This invention illustrates a centering positioning fixture for a stacker crane according to an embodiment of the present invention. It includes a platform 1. Two symmetrically arranged cylinders 2 are bolted to the bottom of the platform 1. A base plate 3 is fixedly connected to the output end of each cylinder 2 via a flange. A clamping plate 4 and a clamping plate 5 are slidably connected to the top of the base plate 3. A groove 6, adapted to the clamping plates 4 and 5, is provided on the top of the platform 1. A rubber pad 7 is adhered to the surface of the clamping plate 5. The pad 7 protects the surface of the clamping plate 5, preventing damage from direct contact between the pallet 13 and the clamping plate 5. A motor 8 is bolted to the bottom of the platform 1. A rotating rod 9 is fixedly connected to the output shaft of the motor 8 via a flange. A support rod 10 is rotatably connected to the surface of the rotating rod 9 via a rotating shaft. Both clamping plates 4 and 5 are rotatably connected to the support rod 10 via rotating shafts. A pallet 13 is placed on the top of the platform 1.
[0023] Example 2:
[0024] Figure 1-3 This invention illustrates a centering positioning fixture for a stacker crane according to an embodiment of the present invention. It includes a platform 1. Two symmetrically arranged cylinders 2 are bolted to the bottom of the platform 1. A base plate 3 is fixedly connected to the output end of each cylinder 2 via a flange. A clamping plate 4 and a clamping plate 5 are slidably connected to the top of the base plate 3. A groove 6, adapted to the clamping plates 4 and 5, is provided on the top of the platform 1. A motor 8 is bolted to the bottom of the platform 1. A rotating rod 9 is fixedly connected to the output shaft of the motor 8 via a flange. The surface of rod 9 is rotatably connected to support rod 10 via a pivot. The bottom of clamping plate 1 4 and clamping plate 2 5 are integrally formed with sliders 11. The top of the base plate 3 is provided with a sliding groove 12 that matches the slider 11. Through the cooperation of slider 11 and sliding groove 12, the movement of clamping plate 1 4 and clamping plate 2 5 is limited, preventing clamping plate 1 4 and clamping plate 2 5 from shaking during movement. A cargo plate 13 is placed on the top of the platform 1. A stacking device 14 and a conveying device 15 are provided on the outside of the platform 1.
[0025] Working principle: When using this utility model, the user transports the pallet 13 to the side of the clamping plate 2 5 through the conveying device 15. Then, the cylinder 2 is turned on, which drives the clamping plates 1 4 and 2 5 to rise one position through the base plate 3. Then, the motor 8 is turned on, which drives the rotating rod 9 to rotate. The rotating rod 9 drives the clamping plates 1 4 and 2 5 to move in the plate groove 6 through the support rod 10. This allows the clamping plates 1 4 and 2 5 to be centered on the position of the pallet 13. Then, the clamping plates 1 4 and 2 5 are reset through the cooperation of the motor 8 and the cylinder 2. Then, the stacking device 14 is turned on to stack the pallet 13. This achieves the centered positioning of the goods at the grab position, so that the goods are in the center position when grabbing, thereby ensuring that the stacked goods maintain good regularity.
[0026] In summary, this stacker crane uses a centering positioning fixture. The motor 8 drives the rotating rod 9 to rotate, which in turn moves the clamping plates 4 and 5 via the support rod 10. This allows the clamping plates 4 and 5 to center the position of the pallet 13, thus achieving the goal of centering the goods at the grab position. This ensures that the goods are in the center during grabbing, thereby guaranteeing that the stacked goods maintain good regularity.
