Description

Technical Field

[0001] This invention belongs to the field of automated gripping device technology, and particularly relates to a non-rotating gripper that grips in both directions at 90 degrees. Background Technology

[0002] In high-temperature operating environments such as steel metallurgy, a square component specifically designed for certain equipment—a square fuel tank—is often used as a heat supply unit. This fuel tank has a square cross-section, with an integrated handle along the diagonal of the top surface for easy lifting and handling. Multiple such fuel tanks are typically stored in a dedicated square storage and transport container in a densely packed, staggered arrangement to save space and facilitate bulk transfers.

[0003] Because the fuel tank itself is a square geometry, regardless of its placement within the storage container (i.e., rotation around the vertical axis at any angle), the handle on top has only two possible orientations, and these two orientations are perpendicular to each other, forming a 90-degree angle, as shown in the attached diagram. Figure 7 As shown. Traditional gripping devices often require a rotating mechanism to rotate the jaws 90 degrees to adapt to the direction of the handle when facing handles with different orientations. This not only results in a complex structure and large space occupation, but also usually requires two independent power sources (one for rotation and one for clamping) to complete one gripping cycle, leading to many steps, low efficiency, and high failure rate. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-7 The present invention provides a non-rotating gripper that grips in both directions at 90 degrees, comprising: Mounting rack assembly; The jaw assembly includes two sets of transverse jaws 9 and two sets of longitudinal jaws 13. The two transverse jaws 9 and the two longitudinal jaws 13 are slidably connected to the bottom of the mounting frame assembly, and the opening and closing directions of the two transverse jaws 9 are perpendicular to the opening and closing directions of the two longitudinal jaws 13. A horizontal linkage mechanism is provided between the two opposite side walls of the two transverse jaws 9 and the two opposite side walls of the two longitudinal jaws 13. The horizontal linkage mechanism is used to make the opening and closing movement directions of the two transverse jaws 9 and the two longitudinal jaws 13 opposite. The drive assembly, located within the mounting bracket assembly, is used to actuate the two transverse jaws 9 to perform opening and closing movements.

[0021] The main function of the mounting bracket assembly is to provide structural support and mounting reference for the entire gripper; the main function of the two sets of transverse jaws 9 in the jaw assembly is to perform opening and closing movements along the first direction to clamp or release the handles on the square components in that direction; the main function of the two sets of longitudinal jaws 13 is to perform opening and closing movements along the second direction perpendicular to the first direction to clamp or release the workpiece handles on the square components in that direction; the main function of the horizontal linkage mechanism is to connect the transverse jaws 9 and the longitudinal jaws 13 by hinge, so that the transverse jaws 9 and the longitudinal jaws 13 are linked, and the opening and closing movement of one set of jaws can drive the other set of jaws to perform opening and closing movements in the opposite direction; the main function of the drive assembly is to provide power to drive the two sets of transverse jaws 9 to perform opening and closing movements, and then drive the two sets of longitudinal jaws 13 to achieve linkage through the horizontal linkage mechanism. Overall, this invention achieves the ability to perform gripping and releasing operations in two 90-degree directions without a rotating mechanism by setting up a single drive component, a bidirectional arrangement of the gripper component, and a horizontal linkage mechanism for motion transmission. Furthermore, the gripper does not require overall orientation adjustment, which greatly improves efficiency and simplifies the overall structure.

[0022] Further optimization of the scheme: the mounting bracket assembly includes a connecting plate 4, a cubic connecting block is fixedly connected to the bottom of the connecting plate 4, two horizontal jaws 9 and two vertical jaws 13 are respectively set at the bottom of the connecting plate 4 through the cubic connecting block, a mounting plate 2 is set at the top of the connecting plate 4, and a drive assembly is set between the mounting plate 2 and the connecting plate 4.

[0023] In a further optimized design, several guide screws 11 are horizontally fixedly connected to one set of opposite sidewalls and another set of opposite sidewalls of the cubic connecting block. Two transverse jaws 9 and two longitudinal jaws 13 are slidably connected to the cubic connecting block through several guide screws 11. The two transverse jaws 9 are located on both sides of one set of opposite sidewalls, and the two longitudinal jaws 13 are located on both sides of the other set of opposite sidewalls.

[0024] like Figures 1-2 and Figures 3-4As shown, in this embodiment, eight guide screws 11 are provided, specifically the first guide screw 11-1, the second guide screw 11-2, the third guide screw 11-3, the fourth guide screw 11-4, the fifth guide screw 11-5, the sixth guide screw 11-6, the seventh guide screw 11-7, and the eighth guide screw 11-8, which are fixedly connected in pairs to the four sets of side walls of the cubic connecting block. Meanwhile, the two sets of transverse jaws 9 are respectively configured as the first transverse jaw 9-1 and the second transverse jaw 9-2, and the two sets of longitudinal jaws 13 are configured as the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2. The first transverse jaw 9-1 is slidably sleeved on the first guide screw 11-1 and the second guide screw 11-2; the second transverse jaw 9-2 is slidably sleeved on the third guide screw 11-3 and the fourth guide screw 11-4; the first longitudinal jaw 13-1 is slidably sleeved on the fifth guide screw 11-5 and the sixth guide screw 11-6; and the second longitudinal jaw 13-2 is slidably sleeved on the seventh guide screw 11-7 and the eighth guide screw 11-8.

[0025] Further optimization of the scheme: the horizontal linkage mechanism includes four sets of horizontal linkages 12. The two sides of the two transverse jaws 9 are respectively hinged to one end of the four sets of horizontal linkages 12 through four sets of vertical pins 10. The other ends of the four sets of horizontal linkages 12 are respectively hinged to the two sides of the two longitudinal jaws 13 through another four sets of vertical pins 10.

[0026] As shown in the figure Figure 5 and Figure 6 As shown, the four sets of horizontal links 12 are configured as a first horizontal link 12-1, a second horizontal link 12-2, a third horizontal link 12-3, and a fourth horizontal link 12-4. One end of the first horizontal link 12-1 is hinged to the first transverse jaw 9-1 via a second pin 10-2, and the other end of the first horizontal link 12-1 is hinged to the second longitudinal jaw 13-2 via a third pin 10-3. One end of the second horizontal link 12-2 is hinged to the second longitudinal jaw 13-2 via a fourth pin 10-4, and the other end of the second horizontal link 12-2 is hinged to the second transverse jaw 9-2 via a fifth pin 10-5. One end of the third horizontal link 12-3 is hinged to the second transverse jaw 9-2 via a sixth pin 10-6, and the other end of the third horizontal link 12-3 is hinged to the first longitudinal jaw 13-1 via a seventh pin 10-7. One end of the fourth horizontal link 12-4 is hinged to the first longitudinal jaw 13-1 via the eighth pin 10-8, and the other end of the fourth horizontal link 12-4 is hinged to the first transverse jaw 9-1 via the first pin 10-1. The two sets of transverse jaws 9, the two sets of longitudinal jaws 13, and the four horizontal links 12 form a horizontally closed hinge chain.

[0027] To further optimize the design, the bottom sides of the mounting plate 2 are fixedly connected to the top sides of the connecting plate 4 by several vertical guide posts 3.

[0028] The scheme is further optimized. The driving component includes a sliding guide platform 5 that is slidably connected between several vertical guide columns 3 and a power component set on the mounting plate 2. The power component is used to push the sliding guide platform 5 to move along the vertical guide columns 3. A linkage mechanism is provided between the sliding guide platform 5 and the two transverse jaws 9 to push the two transverse jaws 9 to open and close.

[0029] The scheme is further optimized. The linkage mechanism includes hinge platforms set on both sides of the bottom of the sliding guide platform 5. The connecting line of the two hinge platforms is parallel to the sliding direction of the two transverse jaws 9. One end of the first connecting rod 7 is hinged to one hinge platform through a horizontal pin 6, and one end of the second connecting rod 8 is hinged to the other hinge platform through another horizontal pin 6. The ends of the first connecting rod 7 and the second connecting rod 8 away from the sliding guide platform 5 are respectively hinged to the top of the two transverse jaws 9 through two other horizontal pins 6.

[0030] like Figure 3 and Figure 4 As shown, in this embodiment, there are two first connecting rods 7, which are arranged in parallel to form a double connecting rod structure, and the second connecting rod 8 is located between the two sets of first connecting rods 7.

[0031] In this embodiment, specifically, one end of the first connecting rod 7 is hinged to a hinge platform at the bottom of the sliding guide table 5 via a third pin 6-3, and the other end of the first connecting rod 7 is hinged to the top of the first transverse jaw 9-1 via a fourth pin 6-4. One end of the second connecting rod 8 is hinged to another hinge platform at the bottom of the sliding guide table 5 via a first pin 6-1, and the other end of the second connecting rod 8 is hinged to the top of the second transverse jaw 9-2 via a second pin 6-2. The scheme is further optimized. The power component includes a cylinder 1 that is vertically fixedly connected to the mounting plate 2. The push rod of the cylinder 1 passes through the mounting plate 2 and is fixedly connected to the sliding guide table 5.

[0032] To further optimize the design, U-shaped grooves are provided at the bottom of the two horizontal jaws 9 and the two vertical jaws 13.

[0033] like Figure 1 and Figure 2 As shown, the inner contour of the U-shaped groove is adapted to the handle on top of the square component.

[0034] The design has been further optimized by providing connection holes on the mounting plate 2, which are used to fix the mounting plate 2 to the lifting equipment.

[0035] The working process of this embodiment is as follows: 1. When the handle above the square component is aligned with the line connecting the first transverse jaw 9-1 and the second transverse jaw 9-2, and perpendicular to the line connecting the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2: The initial state of the gripper is set as follows: the cylinder 1 push rod retracts, driving the sliding guide 5 to the top of the vertical direction, the first horizontal gripper 9-1 and the second horizontal gripper 9-2 are in the tightened state, and the first vertical gripper 13-1 and the second vertical gripper 13-2 of the handle perpendicular to the top of the square component are in the open state.

[0036] The gripper is connected to the lifting equipment via mounting plate 2. As the lifting equipment operates, it is positioned directly above the square component. The gripper is then lowered, causing the handle above the square component to engage in the U-shaped grooves of the first transverse jaw 9-1 and the second transverse jaw 9-2. The gripper's positioning and locking are then complete.

[0037] The push rod of the control cylinder 1 extends, and the push rod drives the sliding guide table 5 to the lowest point in the vertical direction. The sliding guide table 5 drives the upper hinge points of the two sets of first connecting rods 7 and second connecting rods 8 to descend. The lower ends of the first connecting rods 7 and second connecting rods 8 drive the first transverse jaw 9-1 and the second transverse jaw 9-2 to move away from each other along the first guide screw 11-1, the second guide screw 11-2, the third guide screw 11-3, and the fourth guide screw 11-4. The first transverse jaw 9-1 and the second transverse jaw 9-2 combine to form an open jaw. When the first transverse jaw 9-1 moves horizontally outward, it reduces the angle between the first horizontal connecting rod 12-1 and the fourth horizontal connecting rod 12-4. When the second transverse jaw 9-2 moves horizontally outward, it reduces the angle between the second horizontal connecting rod 12-2 and the third horizontal connecting rod 12-3. Meanwhile, the first horizontal connecting rod 12-1 and the second horizontal connecting rod 12-2 drive the second longitudinal jaw 13-2. Under the constraint of the seventh guide screw 11-7 and the eighth guide screw 11-8, the second longitudinal jaw 13-2 moves horizontally inward. The third horizontal connecting rod 12-3 and the fourth horizontal connecting rod 12-4 drive the second longitudinal jaw 13-2. Under the constraint of the fifth guide screw 11-5 and the sixth guide screw 11-6, the first longitudinal jaw 13-1 moves horizontally inward. The first longitudinal jaw 13-1 and the second longitudinal jaw 13-2 approach each other, forming a closed state. At this point, the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2 grip the handle above the square component, completing the gripping action. The lifting device is controlled to move the gripper and the square component to the designated position. After the square component is placed and stabilized, the push rod of the control cylinder 1 retracts, and the gripping action is reversed. The combined jaws of the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2 open, and the handle above the square component is released. The combined jaws of the first transverse jaw 9-1 and the second transverse jaw 9-2 close, as they move along the direction of the handle above the square component and do not participate in gripping or releasing the handle. The gripper returns to its initial state, and the lifting device is controlled to disengage the gripper from the handle above the square component, completing the release action of the square component. The gripper is then reset, completing one work cycle.

[0038] 2. When the handle above the square component is perpendicular to the line connecting the first transverse jaw 9-1 and the second transverse jaw 9-2, and aligned with the line connecting the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2, the initial state of the gripper is set as follows: the cylinder 1 push rod extends, the first transverse jaw 9-1 and the second transverse jaw 9-2 perpendicular to the handle above the square component are in the open state, and the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2 are in the tightened state. Referring to the above gripping and releasing operation, the first transverse jaw 9-1 and the second transverse jaw 9-2 complete the gripping and releasing action on the handle above the square component, cooperating with the lifting device to complete the gripping and releasing of the square component.

[0039] Square components are stacked in a dedicated square box. Due to the geometric characteristics of the square components, regardless of the orientation in which they are placed in the box, the handles of the square components will only have two orientations, and they will be at a 90-degree angle. Figure 4 The claw combinations of the first transverse jaw 9-1 and the second transverse jaw 9-2, and the claw combinations of the first longitudinal jaw 13-1 and the second longitudinal jaw 13-2, always have one set parallel to the handle above the square component, while the other set is perpendicular. Therefore, regardless of how the square components are stacked, this gripper always has one set of jaws capable of performing the gripping and releasing actions without requiring rotation of the gripper's overall orientation.

[0040] The alternating opening and closing of two sets of transverse jaws 9 and two sets of longitudinal jaws 13 is achieved by extending and retracting the push rod of a cylinder 1.
