Description

Technical Field

[0001] This utility model relates to the field of coil clamping technology, and to a cylindrical material clamping fixture, and particularly to a cylindrical material clamping fixture that can make full use of the space between densely arranged cylindrical materials. Background Technology

[0002] Robotic arms are widely used in industrial manufacturing, and when used in conjunction with industrial robots, they greatly improve production efficiency and product quality.

[0003] Existing industrial robot manipulators are typically single-headed, with multiple grippers per head. For example, two symmetrical grippers may be used to hold sheet-like or cylindrical objects, while multiple enclosing grippers may be used to grasp round or other irregularly shaped objects. However, for larger cylindrical objects, such as gas canisters or rolled materials, conventional single-headed manipulators not only struggle to achieve stable gripping but also suffer from low gripping efficiency due to their complex structure.

[0004] CN 210500309 U discloses a six-axis dual-head manipulator. Its dual-head design is well-suited for gripping large cylindrical materials, and the rotatable cylinder configuration allows for a wider swing range of the grippers, accommodating materials of various sizes with more stable gripping. It boasts advantages such as a reasonable structural design, convenient installation and use, and high positioning and gripping accuracy and efficiency. Its widespread use will greatly improve production efficiency and product quality. However, while it can solve the problem of gripping and unloading cylindrical materials, its operating space requirement is too large, making it difficult to apply to dense storage facilities for cylindrical materials.

[0005] Therefore, it is of great practical significance to develop a cylindrical material clamp that requires little space for operation and is particularly suitable for dense storage of cylindrical materials. Utility Model Content

[0006] Due to the aforementioned deficiencies in the existing technology, this utility model provides a cylindrical material clamp that requires little operating space and is particularly suitable for cylindrical material storage warehouses, thereby solving the problem that existing cylindrical material clamps require a large operating space and are not suitable for cylindrical material storage warehouses.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cylindrical material clamp includes an X-shaped frame;

[0009] The X-shaped frame includes four outwardly extending extensions distributed in an X shape. The difference between the X-shaped frame and the X-shaped frame is that there are reinforcing connecting parts between adjacent extensions.

[0010] The extension portion has a space for arranging clamping claw drive devices along the length direction of the extension portion, and clamping claw drive devices are provided in the space for arranging clamping claw drive devices.

[0011] The drive end of the gripper drive device is fixedly connected to the material gripper, and the material gripper extends from the gripper drive device arrangement space and passes under the X-shaped frame.

[0012] The gripper drive device of this utility model can adopt a distributed design, that is, each gripper is equipped with a power source, or multiple grippers can be driven simultaneously by one power source.

[0013] This utility model discloses a cylindrical material clamp with a reasonable structural design. The presence of an X-shaped frame is extremely well-suited to the densely arranged cylindrical materials, making full use of the gaps between them. The working space is small, and the clamp can reach the lower part of the material, facilitating loading and unloading. Combined with a dense storage system for cylindrical materials, it overcomes the honeycomb effect of stacked cylindrical materials, greatly improving the effective volume ratio and space utilization of the storage system. The reinforced connection between adjacent extensions in the X-shaped frame significantly improves the overall structural reliability of the frame compared to the standard X-shaped frame, enhancing its load-bearing capacity. Multiple gripping claw drive devices operate simultaneously, causing four material gripping claws to tighten or open synchronously, clamping or releasing the cylindrical materials. The four gripping claws are centered on the X-shaped frame, making them particularly suitable for cylindrical materials. The overall structure is relatively simple, low-cost, small in size, and easy to operate, making it highly promising for application.

[0014] As a preferred technical solution:

[0015] As described above, a cylindrical material clamp has a gripping claw friction-enhancing part on the inner side of the material gripping claw to ensure reliable gripping of the material.

[0016] As described above, in a cylindrical material clamp, the clamping claw driving device is a clamping claw driving cylinder. Only one feasible technical solution is given here; those skilled in the art can also use other linear driving devices, such as drive motors, to achieve linear drive of the clamping claws according to actual needs.

[0017] As described above, a cylindrical material clamp has a hydraulic oil tank and a hydraulic oil pump at the top of an X-shaped frame;

[0018] The gripper drive cylinder is powered by hydraulic oil supplied from the hydraulic oil tank by a hydraulic oil pump.

[0019] As described above, a cylindrical material clamp has a top fixing frame at the top of the X-shaped frame;

[0020] The hydraulic oil tank and hydraulic oil pump are fixed to the top mounting bracket by bolts.

[0021] As described above, in a cylindrical material clamp, the drive end of the clamping claw drive device is fixed to the clamping claw motion guide frame, and the material clamping claw is fixed on the clamping claw motion guide frame. The presence of the clamping claw motion guide frame reduces the load force on the clamping claw drive device in the vertical direction, avoids damage to the clamping claw drive device from long-term clamping of heavy materials, and improves the service life of the equipment.

[0022] As described above, a cylindrical material clamp has clamping claw motion guide frame guide wheels on both sides of the clamping claw motion guide frame;

[0023] The X-shaped frame and the guide wheels of the gripper's motion guide frame are equipped with guide rails at corresponding positions, allowing the gripper's motion guide wheels to slide along the guide rails. The presence of the gripper's motion guide wheels and guide rails provides guidance for the movement of the gripper.

[0024] As described above, a cylindrical material clamping device is a motor-driven device, which includes a lead screw and a lead screw slider threadedly connected to the lead screw, and the lead screw slider is fixedly connected to the material clamping claw.

[0025] The top of the X-shaped frame is equipped with a drive motor, and a drive gear is mounted on the drive shaft of the drive motor. The drive gear meshes with a screw drive gear fixed to the center end of the screw near the X-shaped frame. The drive gear drives the screws of the four sets of gripper drive devices to rotate synchronously, thereby causing the screw slider to move linearly on the screw, which in turn drives the four grippers to move synchronously in a linear fashion, completing the gripping and releasing actions. This provides another form of gripper drive device; of course, other devices capable of linearly driving the grippers can also be applied to this invention. Furthermore, a speed reducer or other transmission device can be installed between the drive motor and the drive gear.

[0026] As described above, in a cylindrical material clamp, the lead screw has guide rails on both sides, and the lead screw slider has grooves on both sides that match the guide rails, with the grooves of the lead screw slider engaging with the guide rails. The cooperation between the guide rails and the grooves of the lead screw slider provides guidance for the linear motion of the lead screw slider, ensuring the smoothness and continuity of its linear motion.

[0027] As described above, in a cylindrical material clamp, the bottom and sides of the clamping claw drive device arrangement space are connected to the outside, and the side connected to the outside is located in the extension portion away from the X-shaped frame end.

[0028] The extension portion is provided with a frame end cap for closure at the end away from the X-shaped frame.

[0029] As described above, the cylindrical material clamp has an X-shaped frame whose orthographic projection is a square with four corners cut off. The cuts are made with the four corners of the square as the center and the cut shape is a quarter circle. This type of frame design can make full use of the gaps between densely arranged cylindrical materials. The clamp can extend into the lower part of the material for loading and unloading. Combined with a dense cylindrical material storage warehouse, it can greatly improve the space utilization of the material storage warehouse.

[0030] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0031] The above-mentioned utility model has the following advantages or beneficial effects:

[0032] (1) The cylindrical material clamp of this utility model has a reasonable structural design. The existence of the X-shaped frame is extremely compatible with the densely arranged cylindrical materials.

Combined with the cylindrical material dense warehouse, it can overcome the honeycomb effect of cylindrical material stacking and greatly improve the effective volume ratio and space utilization of the material warehouse.

[0033] (2) The cylindrical material clamp of this utility model, the reinforced connection between the adjacent extensions in the X-shaped frame can greatly improve the overall structural reliability of the frame and improve the load-bearing capacity of the clamp compared with the X-shaped frame.

[0034] (3) The cylindrical material clamp of this utility model has a clamping claw movement guide frame that reduces the load force of the clamping claw drive device in the vertical direction, avoids damage to the clamping claw drive device by long-term clamping of heavy materials, and improves the service life of the equipment.

Detailed Implementation

[0043] The structure of this utility model will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the utility model.

[0044] Example 1

[0045] A cylindrical material clamp, such as Figures 1-2 As shown, it includes an X-shaped frame 3;

[0046] The X-shaped frame 3 includes four outwardly extending extensions 15 distributed in an X shape. The difference between the X-shaped frame 3 and the X-shaped frame is that there is a reinforcing connection 16 between adjacent extensions 15. The orthographic projection of the X-shaped frame 3 is a square with four corners cut off. The cutting is centered on the four corners of the square and the cutting shape is a quarter circle.

[0047] The extension 15 has a clamping claw drive device arrangement space 7 arranged along the length of the extension 15. The clamping claw drive device arrangement space 7 is equipped with a clamping claw drive device (clamping claw drive cylinder 9). The top of the X-shaped frame 3 is equipped with a hydraulic oil tank 4 and a hydraulic oil pump 5 (the top of the X-shaped frame 3 is equipped with a top fixing frame 6, and the hydraulic oil tank 4 and the hydraulic oil pump 5 are fixed to the top fixing frame 6 by bolts). The clamping claw drive cylinder 9 is driven by hydraulic oil supplied from the hydraulic oil tank 4 by the hydraulic oil pump 5. The bottom and sides of the clamping claw drive device arrangement space 7 are connected to the outside, and the side connected to the outside is located at the end of the extension 15 away from the X-shaped frame 3. The end of the extension 15 away from the X-shaped frame 3 is equipped with a frame end cap 10 for closure.

[0048] The driving end of the gripper drive cylinder 9 is fixed to the gripper motion guide frame 8, and the material gripper 1 is fixed on the gripper motion guide frame 8. Gripper motion guide frame guide wheels 11 are provided on both sides of the gripper motion guide frame 8. The X-shaped frame 3 is provided with guide rails 12 at the corresponding positions of the gripper motion guide frame guide wheels 11. The gripper motion guide frame guide wheels 11 can slide along the guide rails 12. The material gripper 1 extends from the gripper drive device arrangement space and passes under the X-shaped frame. The inner side of the material gripper 1 is provided with a gripper friction-enhancing part 2.

[0049] The application process of the above-mentioned cylindrical material clamp is as follows:

[0050] Use a lifting device to move the cylindrical material clamp directly above the cylindrical material to be clamped. At this point, if... Figure 3 As shown, the outer extension of the cylindrical material clamp 13 is located within the diagonal gap of the cylindrical material 14. The vertical movement of the cylindrical material clamp will not affect other materials stacked adjacent to it. Then, it is lowered down, and the hydraulic pump 5 is controlled to supply oil to the clamping claw drive cylinder 9. The clamping claw drive cylinder 9 drives the clamping claw movement guide frame 8 to slide along the guide slide rail 12, which drives the four material clamping claws 1 to tighten synchronously (the presence of the guide slide rail 12 and the clamping claw movement guide frame 8 can greatly reduce the force on the clamping claw drive cylinder 9 in the vertical direction and avoid damage to the clamping claw drive cylinder 9), thus completing the clamping of the cylindrical material 14.

[0051] Example 2

[0052] A cylindrical material clamp, such as Figures 4-5As shown, it is basically the same as Embodiment 1, except for the gripper drive device. The gripper drive device includes a lead screw 20 and a lead screw slider 21 threadedly connected to the lead screw 20. The lead screw slider 21 is fixedly connected to the material gripper 1. A drive motor 17 is provided on the top of the X-shaped frame 3. A drive gear 18 is mounted on the drive shaft of the drive motor 17. The drive gear 18 meshes with a lead screw drive gear 19 that is fixedly mounted on the lead screw 20 near the center end of the X-shaped frame 3. Guide rails 23 are provided on both sides of the lead screw 20. Slots 22 that match the guide rails 23 are opened on both sides of the lead screw slider 21, and the slots 22 of the lead screw slider 21 are engaged with the guide rails 23. Here, a vertically arranged drive motor design is given. Of course, the drive motor can also be arranged horizontally, and the direction change can be achieved by using a transmission structure.

[0053] Verification has shown that this utility model's cylindrical material clamp has a reasonable structural design. The presence of the X-shaped frame is extremely well-suited to densely arranged cylindrical materials, making full use of the gaps between them. The working space is small, and the clamp can reach into the lower part of the material, facilitating loading and unloading. Combined with a dense storage silo for cylindrical materials, it overcomes the honeycomb effect of stacked cylindrical materials, greatly improving the effective volume ratio and space utilization of the storage silo. The reinforced connection between adjacent extensions in the X-shaped frame significantly improves the overall structural reliability of the frame compared to the standard X-shaped frame, increasing its load-bearing capacity. The presence of the clamping claw movement guide reduces the load on the clamping claw drive device in the vertical direction, preventing damage from prolonged clamping of heavy materials and extending the equipment's service life. The overall structure is relatively simple, the cost is low, the size is small, and the operation is convenient, making it highly promising for application.
