Problems solved by technology
However, when the jaws of the manipulator are clamping the workpiece 104 to the destination, the manipulator must use another power source to lift the workpiece 104 after clamping and before displacement, which highlights the defect of insufficient efficiency.
In addition, this patent document has the following defects: the jaws of the manipulator cannot be turned upside down, otherwise the jaws cannot maintain the clamping force
However, when the jaws 111 of the manipulator are in the process of clamping the workpiece 114 to the destination, the manipulator must use another power source to lift the workpiece 114 after clamping and before displacement, which highlights the defect of insufficient efficiency
In addition, this prior patent has the following defects: the structure of the gripper 111 of the manipulator is complicated, and the operation procedure is too complicated
Although the clamping device has the function of lifting upwards while clamping the workpiece 125 in the process of clamping the workpiece 125 to the destination, the clamping device must pass through the gear 121, the lead screw 122 and Link mechanism 123 is achieved, especially by link mechanism 123 as the usefulness of clamping workpiece 125, so as to highlight the defects of complex structure and insufficient structural rigidity. Finally, the link mechanism 123 limits the movement of the jaws 124, making it impossible to change, or to clamp workpieces 125 of other sizes

Embodiment Construction
[0046] refer to Figure 2 to Figure 5 As shown, the clamping jaw 100 with the function of vertically lifting the workpiece provided by the embodiment of the present invention is mainly suitable for being assembled on the robot arm 91 and controlled by the robot arm 91 for actuation. The gripper 100 with the function of vertically lifting the workpiece is mainly composed of a body 20, two opening and closing sliders 30, two fingers 40, and two elastic components 50, wherein:
[0047] The main body 20 is assembled on the mechanical arm 91, and has a sliding direction 21 and a lifting axis 23 forming a first angle 22 with the sliding direction 21; in this embodiment, the first angle 22 is ninety Spend.
[0048] The two opening and closing sliders 30 can be slid on the body 20 along the sliding direction 21 to approach or move away from each other and are respectively located on both sides of the lifting axis 23, and each has a second sliding block forming a second sliding direct...

The invention provides a clamp capable of raising a workpiece vertically. The clamp comprises a body with a sliding direction and a raising axis forming a first included angle with the sliding direction; a plurality of opening and closing slide blocks arranged on the body in a sliding manner in a manner capable of being mutually closing to or far from each other along the slide direction, respectively located at tow sides of the raising axis, and respectively comprising an accommodating groove forming a second included angle with the sliding direction; and a plurality of fingers respectively arranged in the accommodating grooves of the opening and closing slide blocks in a telescoping and movable manner and respectively comprising a finger portion located outside the accommodating groove and used for clamping a workpiece. Therefore, during position raising of the opening and closing slide blocks, the fingers are contracted inwardly in the corresponding accommodating grooves so that each finger portion clamps the workpiece and enables the workpiece to vertically raise a distance towards the direction of the body along the raising axis.
Description
technical field [0001] The present invention relates to a clamping jaw, in particular to a clamping jaw with the function of vertically lifting a workpiece. Background technique [0002] refer to Figure 1A As shown, one of the diagrams of the Japanese patent (JP 2007118148A) is shown. This patent document is a gripper of a manipulator, which mainly uses a spring 101 with a wedge mechanism composed of a finger body 102 and a gripper 103 to increase grip When clamping the workpiece 104, if the workpiece 104 slides downwards, it will drive the jaws 103 of the clamping jaws to move downward together. At this time, an inward clamping force will be generated to ensure that the workpiece 104 does not fall. However, when the jaws of the manipulator are clamping the workpiece 104 to the destination, the manipulator must use another power source to lift the workpiece 104 after clamping and before moving, which highlights the defect of insufficient efficiency. In addition, this paten...
