Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] see Figure 1-10 , a multi-arm multi-degree-of-freedom arm structure, comprising a base plate 1, a first mechanical arm 2 is fixedly connected to the outer surface of the upper end of the base plate 1, and a second mechanical arm 3 is hinged on the outer surface of the upper end of the first mechanical arm 2 through a spherical hinge. A third robotic arm 4 is slidably connected to the outer surface of the right side of the second...

Abstract

The multi-arm multi-degree-of-freedom arm type structure relates to the technical field of arm type structures and comprises a protection mechanism, a motor fixedly connected to the left side position of the inner surface of a second mechanical arm, a rotating shaft fixedly connected to the outer surface of the right side of the motor, and a reciprocating lead screw fixedly connected to the outer surface of the right end of the rotating shaft. The sliding block is slidably connected to the left edge of the outer surface of the reciprocating lead screw, the first spring is fixedly connected to the right outer surface of the sliding block, the push plate is slidably connected to the right edge of the outer surface of the reciprocating lead screw, and the sealing belt is fixedly connected between the sliding block and the outer surface of the push plate. Lubricating liquid stored in the machining box can be discharged through a sealing ring through reciprocating movement of a push plate, the position between the second mechanical arm and the third mechanical arm can be lubricated, and the situation that due to long-time use of an arm type structure, the mechanism is seriously abraded is prevented; and then a reciprocating lead screw can drive a first connecting shaft to move the third mechanical arm, operation is convenient and fast, and meanwhile the mechanical structure can be protected.

Description

technical field [0001] The invention relates to the technical field of arm structures, in particular to a multi-arm multi-degree-of-freedom arm structure. Background technique [0002] With the rapid development of modern science and technology, the requirements for mechanization, automation and intelligence in all walks of life are getting higher and higher. Robot technology will definitely become the core trend of modern science and technology development, and play a prominent role in agriculture, logistics and transportation, automobile manufacturing and other industries. In order to improve agricultural productivity, liberate people's work intensity, and improve the working environment. [0003] In the existing arm structure, there will be friction between many structures in the process of use. If the lubrication cannot be carried out intermittently, it may cause serious wear of the structure, accelerate the aging of the device, and cause the device to be scrapped. [0...
