Improved mechanical hand

Abstract

The invention discloses an improved mechanical hand. The improved mechanical hand is characterized in that a hand part comprises a palm and knuckles; the knuckles include the upper knuckles and the lower knuckles; a transmission mechanism, the palm, the upper knuckles and the lower knuckles are sequentially connected; a palm limiting sliding rail is arranged in the palm; the upper knuckles are installed in the palm limiting sliding rail; a knuckle limiting sliding rail is arranged in each upper knuckle; the lower knuckles are installed in the knuckle limiting sliding rails; each lower knuckle comprises a lower knuckle upper half part and a lower knuckle lower half part, wherein a linking part is arranged between the lower knuckle lower half part and the lower knuckle upper half part and is used for inwards bending the lower knuckle lower half part; and an electromagnetic suction cup is arranged on the lower side of the palm. The improved mechanical hand has the beneficial effects that clamping and electromagnetic attraction can be conducted by the mechanical hand at the same time, mechanical hand fingers can be retracted inside when objects cannot be clamped, iron objects are transferred through electromagnetic attraction, and the objects can be transported more safely and stably and more conveniently.

Description

technical field [0001] The invention relates to an improved manipulator and belongs to the technical field of machinery. Background technique [0002] The manipulator is a very common tool in today's society. It is not only used in industrial production, but also in medical care, education and other aspects. Common manipulators often can only carry out single clamping or adsorption to carry items. When carrying heavy iron items, the items may fall due to overweight. Even if some manipulators have more functions, when encountering iron objects that are not easy to clamp, the manipulator fingers are often in the way, and the manipulator fingers cannot be removed. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide an improved manipulator, which can not only carry out clamping and electromagnetic adsorption at the same time, but also retract the fingers of the manipulator insi...
