Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0013] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so as to implement the embodiments of this application described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.
[0014] In this application, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation or be constructed and operated in a specific orientation.
[0015] Moreover, in addition to being able to represent an orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.
[0016] In addition, the terms "installed", "set up", "provided with", "connected", "linked", "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0017] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.
[0018] See Figures 1 - 2 , this embodiment provides a jaw applicable to a robotic arm, including a connecting plate 10. A male connector 11 is provided on one side of the connecting plate 10, and the male connector 11 is used to connect with a female connector on the robotic arm. A clamping cylinder 12 is provided on the other side of the connecting plate 10. Both ends of the clamping cylinder 12 are output ends and are respectively provided with a first clamping plate 13 and a second clamping plate 14. Among them, a clamping groove 131 is formed on the first clamping plate 13, and two groups of positioning pins 141 are provided on the second clamping plate 14.
[0019] An installation plate 17 is provided on the body of the clamping cylinder 12 between the first clamping plate 13 and the second clamping plate 14. A detection device 15 is provided on the installation plate 17. The detection device 15 includes a detection sensor 151, and a touch probe 152 is provided on the detection sensor 151. The touch probe 152 is used to touch the touch switch on the detection sensor so that the detection sensor can receive a signal.
[0020] Two groups of support columns 16 are also provided on the installation plate 17. A pressing component is provided at the machining position of the part to press the clamped part against the support columns 16. At the same time, in order for the part to contact the touch probe 152, the touch probe 152 protrudes from the supporting end face of the support column 16. After the part is clamped, the part presses the touch probe 152 inward, causing the touch probe to contact the touch switch. At this time, the detection sensor receives the signal that the jaw has clamped the part.
[0021] When the part needs to be grasped, the robotic arm drives the jaw to move to the position of the part. The clamping cylinder 12 is activated, driving the first clamping plate 13 and the second clamping plate 14 to open, and then the part is clamped through the clamping groove 131 and the positioning pins 141. When the jaw needs to be replaced, only the male connector 11 needs to be removed from the female connector on the robotic arm.
[0022] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
