Description

Technical Field

[0001] The utility model is applied to the technical field of loading and unloading clamps, and particularly relates to a loading and clamping mechanism. Background Art

[0002] In the production of new energy vehicles, different component modules, such as batteries, powertrain motors, and fuel tanks, need to be assembled and connected. During the installation of the powertrain motors, components such as wave washers need to be installed. Currently, these components are mainly installed manually, which results in high labor costs and high workload. Long production hours can easily lead to fatigue, low efficiency, and insufficient production line utilization. Manual labor leads to poor production process stability, unstable production efficiency, and high defect rates. Alternatively, the components are clamped and installed using a robot-driven gripper. However, existing grippers primarily utilize a dual-jaw structure, which compresses the outer edge of the wave washers for transfer and assembly. Due to the unique shape of the wave washers, this dual-jaw structure is prone to slippage or displacement during the gripping process, causing the wave washers to fall off. Furthermore, the gripper is not adaptable to a wide range of products of different specifications, resulting in low efficiency. A simple, compatible, and adaptable clamping mechanism capable of adjusting the clamping force according to the cylinder diameter, a modular design that allows for rapid jaw replacement, and a multi-jaw design that ensures efficient product clamping could address these issues.

[0019] like Figures 1 to 6As shown, in this embodiment, the utility model includes a base 1, a driving module 2 and a clamping module 3, the driving module 2 includes a plurality of driving cylinders 4 and a plurality of pressure blocks 5, the plurality of driving cylinders 4 are evenly arranged at the upper end of the base 1, the clamping module 3 is arranged at the lower end of the base 1, the clamping module 3 includes a balance plate 6 and a plurality of clamping modules 7, the driving ends of the plurality of clamping modules 7 are connected to the lower end surface of the balance plate 6, the base 1 is connected to the fixed ends of the plurality of clamping modules 7 through a plurality of guide rods 8, the plurality of driving cylinders 4 drive the plurality of pressure blocks 5 to cooperate with the upper end surface of the balance plate 6 so that the clamping ends of the plurality of clamping modules 7 are synchronously opened or restored. It can be seen that the clamping jaw module 3 is a three-claw design, and several of the driving cylinders 4 drive the pressure block 5 to make the balance plate 6 rise or fall. The balance plate 6 drives the three groups of the clamping jaw modules 7 to open, press or restore synchronously. The three-claw positioning and clamping on the inner diameter of the product can effectively prevent the product from sliding and deflecting and causing it to slip. It has a simple structure, strong applicability, and higher clamping efficiency.

[0020] like Figures 3 to 5 As shown, in this embodiment, the clamping jaw module 7 includes a clamping jaw cylinder 9, an ejector pin 10, and an L-shaped clamping jaw 11. A first hinge hole 12 and a second hinge hole 13 are respectively provided in the middle portion and at the end away from the clamping position of the L-shaped clamping jaw 11. The first hinge hole 12 is hinged to the lower end of the clamping jaw cylinder 9, and the ejector pin 10 passes through a through hole 14 in the middle portion of the clamping jaw cylinder 9 and is hinged to the second hinge hole 13. It can be seen that the second hinge hole 13 is hinged to the lower end of the clamping jaw cylinder 9, allowing the L-shaped clamping jaw 11 to rotate around the middle angle as the center. The lifting and lowering of the ejector pin 10 drives the L-shaped clamping jaw 11 to rotate, thereby achieving clamping and loosening.

[0021] like Figure 1 and Figure 2 As shown, in this embodiment, a plurality of guide rods 8 are evenly spaced and arranged at the upper end of the base 1. A plurality of first springs 15 are also provided at the lower end of the base 1. The upper end of the clamping jaw cylinder 9 is fixed in place by the guide rods 8 and the first springs 15 in a floating engagement with the base 1. Thus, the plurality of first springs 15 provide downward pressure cushioning and recovery effects during the raising and lowering of the plurality of clamping jaw modules 7.

[0022] like Figures 3 to 5 As shown, in this embodiment, a second spring 16 is further provided between the ejector pin 10 and the upper end of the clamping jaw cylinder 9. The ejector pin 10 is in floating engagement with the clamping jaw cylinder 9 via the second spring 16. Thus, when the ejector pin 10 presses downward to drive the L-shaped clamping jaw 11 to rotate and press together, the second spring 16 provides a buffering effect to prevent over-pressing of the product.

[0023] like Figure 3 and Figure 4 As shown, in this embodiment, the outer contact surface of the L-shaped clamping jaw 11 is provided with an anti-slip groove 17. It can be seen that the anti-slip groove 17 can increase the pressing friction force and prevent the product from shifting during the clamping process.

[0024] like Figure 1 and 6 As shown, in this embodiment, the base 1 is provided with a plurality of limiting holes 18 on its side, and the guide rod 8 is provided with a limiting slot 19 in the middle thereof, and the limiting holes 18 cooperate with the limiting slot 19. Thus, it can be seen that the limiting holes 18 and the limiting slot 19 cooperate with each other via the limiting pin, thereby preventing the L-shaped clamping jaw 11 from rotating and deviating during operation of the device.

[0025] like Figure 1 As shown, in this embodiment, the upper end surface of the base 1 is further provided with a plurality of fixing blocks 20, and the base 1 is connected to the external lifting module via the fixing blocks 20. Thus, the fixing blocks 20 can be equipped with a variety of external lifting mechanisms, and the installation and operation are convenient.

[0026] like Figure 1 As shown, in this embodiment, a bushing 21 is provided between the guide rod 8 and the upper end surface of the base 1. It can be seen that the bushing 21 provides protection for the guide rod 8 during the operation of the equipment.

[0027] The working principle of the present utility model is as follows: before the equipment is started, the fixed block 20 is connected to the external manipulator or lifting mechanism, and some of the L-shaped jaws 11 are in a retracted state. When the equipment is started, the external manipulator or lifting mechanism transfers some of the L-shaped jaws 11 to the product loading position and penetrates into the interior of the product. Some of the driving cylinders 4 drive the pressing blocks 5 to descend, and some of the pressing blocks 5 contact the balance plate 6 and drive the balance plate 6 to descend synchronously. The balance plate 6 drives the three groups of the ejectors 10 to descend, and the three groups of the ejectors 10 drive the three groups of the L-shaped jaws 11 to rotate synchronously with the lower end of the clamping cylinder 9 as the center. The three groups of the L-shaped jaws 11 contact the inner diameter of the product and continue to press. After completing the pressing, the product is transferred. After reaching the assembly position, the movable ends of the driving cylinders 4 are reset, and the three groups of the L-shaped jaws 11 are reset synchronously to complete the unloading. Repeat the above steps to achieve clamping of the inside of the product.

[0028] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
