Description

Technical Field

[0001] The utility model relates to a clamping claw, in particular to a clamping claw used for loading and unloading materials. Background Art

[0002] During the riveting process of parts, some parts require multiple rivets for multiple riveting. Before the last riveting action is completed, the parts need to be loaded, and after the riveting is completed, the parts need to be unloaded. In the existing technology, some loading and unloading processes are performed manually, which is not only inefficient but also dangerous. Generally, a robotic arm is used with a set of grippers to perform the loading and unloading process. The existing robotic arm unloads the parts after the last riveting is completed, and then moves to the previous process to transport the parts to the last riveting station, which results in relatively low efficiency.

[0016] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0017] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0018] In this application, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0019] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0020] Furthermore, the terms "installed," "disposed," "provided with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] See also Figure 1-Figure 3 This embodiment provides a clamp for loading and unloading materials, including an L-shaped mounting bracket 10. A mounting hole 11 is set at the corner of the L-shaped mounting bracket 10 for connecting to a robotic arm. A loading mechanism 30 and a unloading mechanism 20 are respectively set at both ends of the L-shaped mounting bracket 10. Since the structures of the loading mechanism 30 and the unloading mechanism 20 are consistent, this embodiment is described using the loading mechanism 30 as an example.

[0023] The feeding mechanism 30 includes a feeding cylinder 31. Two sets of sliders 32 are set at the output end of the feeding cylinder 31. Clamps 33 are respectively set on the two sets of sliders 32. The feeding cylinder 31 drives the two sets of clamps to move outward so that the clamps clamp the parts from the inner hole of the parts.

[0024] Specifically, the splint 33 includes a connecting portion 331 and a clamping portion 332. The connecting portion 331 is used to connect the slider 32. The clamping portion 332 is provided with a clamping groove 333. The two groups of clamping grooves 333 are provided in opposite directions, that is, they are respectively provided on the outside of the splint to Figure 1For example, a limiting step 334 is provided at the upper position of the clamping groove 333, so that when the clamping jaws descend, the limiting step 334 contacts the part from above, and then the clamping plate 33 moves to both sides.

[0025] In order to facilitate the positioning of parts, a plurality of first positioning columns 34 are also provided on the mounting bracket 10 for positioning the inner hole position of the parts, wherein the first positioning column 34 is the positioning column of the loading mechanism. Since the loading mechanism transports the parts to the last riveting station and then rivets different workpieces together, the positions of the first positioning column 34 and the second positioning column in the unloading mechanism are different.

[0026] In order to detect whether the clamping jaws have moved to the correct position, a clamping jaw detection sensor 35 is provided on the mounting bracket 10. At the same time, in order to detect whether the clamping jaws have clamped the workpiece, a workpiece detection sensor 36 is also provided on the mounting bracket. When the workpiece touches the touch switch of the workpiece detection sensor 36, it indicates that the workpiece has been grasped.

[0027] The clamp of the present application is installed on the robotic arm. When the last riveting process needs to be loaded and unloaded, the robotic arm drives the clamp to move to the previous process, the clamp 33 extends into the inner hole of the part, the loading cylinder 31 is started, and drives the clamp to move to both sides to clamp the workpiece, and then the robotic arm moves the workpiece to the riveting position. First, the unloading mechanism is started to grab the workpiece, and then the robotic arm drives the mounting bracket to rotate, and the clamp of the loading mechanism places the workpiece in the riveting position, and then the unloading mechanism completes the unloading.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
