Multifunctional mechanical arm

Abstract

The invention relates to the technical field of industrial machines, in particular to a multifunctional mechanical arm. The multifunctional mechanical arm comprises a mechanical arm body and further comprises a plurality of work heads and a coupling device matched with the work heads. The mechanical arm body outputs power to the work heads through the coupling device, and the work heads are telescopically mounted on a mounting rack. The coupling device comprises a fixed barrel arranged at one end of the mechanical arm body, an air pump arranged in the fixed barrel and a coupler with one end connected to the air pump, and the other end of the coupler is matched with the work heads. According to the technical scheme, the multifunctional mechanical arm has the following beneficial effects that the structure is simple, the technology is reasonable, and use is convenient; the mechanical arm body is connected with the work heads with different functions through displacement of the coupler, and multiple functions of the mechanical arm are achieved; and an elastic element of the coupler is long in service life, excellent weather fastness, bending fatigue resistance, fire resistance and corrosion resistance are achieved, and therefore use is facilitated, and the service life of the mechanical arm is prolonged.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, in particular to a multifunctional mechanical arm. Background technique [0002] At present, with the continuous development of industrial machinery, many equipment can realize automatic operation, and many products can be produced through automation. And mechanical arm is indispensable in industrial mechanical equipment, but the function of existing mechanical arm is all comparatively single, generally a kind of mechanical arm can only realize a kind of function. [0003] Most of the elastic elements of the existing shaft couplings for manipulators are cast from polyurethane monomers. Polyurethane has excellent elasticity and abrasion resistance. However, the flex fatigue resistance is poor. Due to the high cohesive energy of polyurethane, internal heat is generated during compression by external force, which makes the internal temperature of the component rise, and the molecular...

Problems solved by technology

At the same time, the service life of existing polyurethane (TPU) elastomer components is generally 2 months, which is short

But the replacement of this component is troublesome, which greatly increases the workload of the staff
