Description

Technical Field

[0001] The utility model relates to the field of arm clamps, in particular to a robot arm clamp. Background Art

[0002] A robotic arm gripper is a device mounted at the end of a robot arm, primarily used to grip and move objects. It typically mimics the movements of human fingers, enabling simple manipulation by gripping objects and helping the robot perform various tasks. Robotic arm grippers can be categorized into several types, including vacuum suction cups, soft grippers, parallel two-finger grippers, and multi-finger dexterous hands. Vacuum suction cups control air pumps to pick up objects and are suitable for smooth, lightweight objects. Soft grippers are made of flexible materials and can adaptively wrap around target objects, making them suitable for odd-shaped and fragile items.

[0003] Most of the robot arm fixtures in the existing technology are controlled by the rear-end arm, but they usually only have one set of mechanical fixtures, and only one model can be selected for the fixture, which has a limited scope of application. When facing different work requirements, they cannot effectively adapt to the corresponding needs, and the equipment or fixtures need to be replaced, which is more troublesome. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and shortcomings. Utility Model Content

The outer shell 31 and the inner shell 52 cooperate with each other to facilitate better external protection and sealing of the motor 4, thereby maintaining the safety of the motor 4.

[0024] Preferably, the clamping assembly 6 includes a fixing base 61, an upper clamp 62 and a lower clamp 63 are respectively installed at the upper and lower ends of the fixing base 61, a second flange 611 is provided on the side of the fixing base 61, and a plurality of connecting bolts 7 are fixed between the second flange 611 and the first flange 51, fixing holes 65 are respectively opened at the upper and lower ends of the fixing base 61, and embedded holes 68 are correspondingly opened on the upper clamp 62 and the lower clamp 63, and fixing bolts 67 are connected between the fixing holes 65 and the embedded holes 68, four groups of positioning holes 64 are respectively opened at the upper and lower ends of the fixing base 61, and four groups of positioning blocks 66 are respectively provided at the bottom of the upper clamp 62 and the lower clamp 63, and the positioning blocks 66 are respectively inserted into the positioning holes 64;
