Problems solved by technology

The existing mechanical arm is generally composed of three parts, the big arm, the small arm and the finger part. In different application fields, according to the nature of their work, these three parts of the robot mechanical arm need to be specially designed, such as large The length of the arm and the forearm, as well as the degree of bending and rotation, etc., which make the use range of a robot arm narrow, the use area is limited, the application function is single, and its maintenance and replacement costs are also high

Embodiment 1

[0024] Such as Figure 1~2As shown, a robot modular assembly mechanical arm of the present invention includes an arm body, and the arm body includes a plurality of interconnected arm sections 1, and each section arm section 1 includes a rectangular block 2, on opposite sides of the rectangular block 2 One end is respectively provided with a bump 3, and one of the bumps 3 is fixed with a fixed shaft 4, and one end of the fixed shaft 4 is provided with a driving installation hole 5 communicating with the outside world, and the other end is provided with a fixing hole 6, and in the fixing hole The inner wall of 6 is provided with at least one annular groove 7 and chute 8, one end of said chute 8 communicates with the annular groove 7, the other end is flush with the mouth of the fixing hole 6, and a moving shaft is arranged in the other protruding block 3 9. One end of the moving shaft 9 protrudes from the surface of the bump 3, and the protruding end matches the fixing hole 6 an...

Embodiment 2

[0028] Such as Figure 1~2 As shown, on the basis of Embodiment 1, the end of the fixed shaft 4 or the moving shaft 9 having the drive installation hole 5 is a spherical body, and the diameter of the spherical body is 1.25 of the diameter of the wall of the fixed shaft 4 or the moving shaft 9. ~1.55 times. The above structure can effectively prevent the fixed shaft and the moving shaft from falling off from their respective protrusions; Disperse the external axial stress on the rotor, reduce the radial deformation of the connecting section of the rotor, and improve the service life of the fixed and moving shafts.

[0029] In addition, the inventor tested the relationship between the diameter of the spherical end of the rotor and the radial deformation of the rotor, and applied an axial stress test of 170MP to the rotor. Some test results are as follows:

[0030]

[0031] From the table above, it can be seen that if the diameter of the spherical body is designed to be 1.25...

Embodiment 3

[0033] Such as Figure 1~3 As shown, on the basis of Embodiment 1, a positioning rod 12 is also provided on the bump 3 where the fixed rotating shaft 4 is located, and an annular positioning groove 13 is also opened on the convex block 3 where the moving rotating shaft 9 is located. The centerline coincides with the central axis of the moving shaft 9, and the annular positioning groove 13 is filled with lubricating oil. There are several threaded holes 14 on the bottom surface of the annular positioning groove 13, and the threaded holes 14 are equidistantly arranged around the centerline of the annular positioning groove 13, and also include two stop screws 15, the diameter of the stop screw 15 is the same as that of the ring. The inner diameters of the positioning grooves 13 are equally large. The above structure helps the fixed shaft 4 and the moving shaft 6 to be aligned and connected, and limits the position after the fixed shaft 4 and the moving shaft 6 are connected. m...

Abstract

The invention discloses a robot modular assemble mechanical arm. The robot modular assemble mechanical arm comprises an arm body which includes a plurality of arm sections connected with one another;each arm section comprises a rectangular block, the opposite ends of the rectangular block are each provided with a convex block, a fixed rotation shaft is fixed into one of the convex blocks, one endof the fixed rotation shaft is provided with a driving installation hole communicating with the outside, the other end of the fixed rotation shaft is provided with a fixing hole, the inner wall of the fixing hole is provided with at least one annular groove and a slide groove, one end of the slide groove communicates with the annular grooves, the other end of the slide groove is flush with an opening of the fixing hole, a moving rotation shaft is arranged in the other convex block, one end of the moving rotation shaft protrudes out of the surface of the convex block, and the protruding end ismatched with the fixing hole, can enter the annular grooves along the slide groove and is limited in the annular grooves. The robot modular assemble mechanical arm is formed by assembling the moduledetachable structure, can be freely assembled and lengthened according to the operation environment and is high in flexibility and universality and capable of adapting to various operations.

Description

technical field [0001] The invention relates to the field of robot arms, in particular to a robot modular assembly robot arm. Background technique [0002] Robotic manipulator is a mechanical device that can automatically complete the transmission or operation of objects (such as materials, workpieces, parts or tools, etc.) according to established procedures or requirements. It can partially replace human manual labor and complete more complex tasks. Operation. Robotic manipulators are widely used in semiconductor manufacturing, industry, medical, military, and space exploration and other fields. The existing mechanical arm is generally composed of three parts, the big arm, the small arm and the finger part. In different application fields, according to the nature of their work, these three parts of the robot mechanical arm need to be specially designed, such as large The length of the arm and forearm, as well as the degree of bending and rotation, etc., make a robot arm ...
