[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings, but the embodiments of the present utility model are not limited thereto.

[0024] As Figure 1-Figure 4 shown, this embodiment provides a multi-axis linkage industrial robotic arm, including a robotic arm body 1 and a cylindrical base 2 installed at the bottom of the robotic arm body 1. A fixing plate 3 is horizontally fixed at the bottom end of the cylindrical base 2. Mounting holes are provided at the four corners of the fixing plate 3. C-shaped plates 4 are fixed at the middle positions on the sides of the fixing plate 3. A rotating rod 5 is rotatably installed between the two sides of the C-shaped plate 4. A jaw 6 is fixed on the rotating rod 5. A flipping mechanism for controlling the up and down rotation of the jaw 6 is provided at the bottom end of the jaw 6. A moving mechanism is provided at the bottom of the cylindrical base 2.

[0025] Overall working principle: During the installation of the device, if the outer surface of the mounting seat is smooth and lacks positioning points, clamping fixation at this time will result in poor stability of the device. Therefore, in this case, the bolt fixation method is selected. The fixing plate 3 is attached to the surface of the mounting seat, and the mounting holes are aligned with the through holes on the mounting seat, and fixed with bolts. Additionally, if the surface of the mounting seat is not smooth and has corresponding clamping points, at this time, the fixing plate 3 is attached to the top of the mounting seat, and the flipping mechanism is used to control the jaw 6 to flip downward, and the jaw 6 clamps and limits the outer surface of the mounting seat, enabling rapid disassembly and assembly. The dual installation methods coexist, with stronger applicability. After the device is disassembled, the device can be quickly moved through the moving mechanism at the bottom of the cylindrical base 2 for maintenance.

[0026] In this embodiment, the flipping mechanism includes a groove 7, a worm gear 8 and a worm 9. The groove 7 is opened at the bottom end of the clamping jaw 6. The rotating rod 5 passes through the inside of the groove 7. A worm gear 8 is provided inside the groove 7. The worm gear 8 is fixed on the rotating rod 5. A worm 9 is meshed and installed at the top of the worm gear 8. The worm 9 is rotatably installed at the top of the U-shaped plate 4. A rotating mechanism is provided at the end of the worm 9.

[0027] Local working principle: During the process of controlling the flipping of the clamping jaw 6, by controlling the rotation of the worm 9, the worm 9 will control the rotation of the worm gear 8. The worm gear 8 drives the rotation of the rotating rod 5 and the flipping adjustment of the clamping jaw 6 to clamp and position the device.

[0028] In this embodiment, the rotating mechanism includes a gear 10 and a toothed disc 11. The gear 10 is fixed at the end of the worm 9. The toothed disc 11 is rotatably installed at the bottom end outside the cylindrical base 2. The top of the toothed disc 11 is meshed with the gear 10.

[0029] Local working principle: By controlling the rotation of the toothed disc 11, the simultaneous rotation of multiple groups of gears 10 can be driven. Therefore, the worms 9 on the gears 10 will rotate simultaneously, and multiple groups of clamping jaws 6 will be flipped and adjusted simultaneously.

[0030] In this embodiment, insertion holes are evenly formed in the circumferential direction on the outside of the toothed disc 11, and adjusting rods are inserted into the insertion holes.

[0031] Local working principle: During the rotation adjustment of the toothed disc 11, by inserting the adjusting rod into the insertion hole and拨动 the adjusting rod to drive the rotation of the toothed disc 11. If the position of the adjusting rod is blocked, the position of the insertion hole can be changed, making the operation and use more convenient.

[0032] In this embodiment, there are four groups of clamping jaws 6, and the included angle between adjacent clamping jaws 6 is 90°. Clamping openings are provided on the outside of the top ends of the clamping jaws 6.

[0033] Local working principle: The clamping and fixing are carried out through multiple groups of clamping jaws 6, and the installation stability is higher.

[0034] In this embodiment, the moving mechanism includes an installation groove 12, a strip-shaped groove 13, a cross bar 14, an internal threaded ring 15, an annular groove 16, an installation plate 17 and a universal wheel 18. The installation groove 12 is opened at the bottom end of the cylindrical base 2. Strip-shaped grooves 13 are evenly and vertically formed in the circumferential direction on the outside of the cylindrical base 2. Cross bars 14 are slidably provided inside the strip-shaped grooves 13. One ends of multiple groups of cross bars 14 located inside the installation groove 12 are connected to each other. An internal threaded ring 15 is threadedly installed on the outside of the cylindrical base 2. An annular groove 16 is formed inside the internal threaded ring 15. The ends of the cross bars 14 all extend into the annular groove 16. An installation plate 17 is fixed at the bottom of the cross bars 14 located inside the installation groove 12. Universal wheels 18 are evenly installed at the bottom end of the installation plate 17.

[0035] Local working principle: When the device needs to be controlled to move, the inner screw ring 15 is rotated to control the cross bar 14 to move downward along the strip groove 13. The mounting plate 17 at the bottom of the cross bar 14 moves downward at the same time, and the universal wheel 18 at the bottom of the mounting plate 17 contacts the ground, which can push the device to move.

[0036] In this embodiment, the outer side of the inner screw ring 15 is uniformly provided with anti-slip grooves along the circumferential direction, and the anti-slip grooves are perpendicular to the horizontal plane.

[0037] Partial working principle: in the process of controlling the rotation of the inner screw ring 15 , the setting of the anti-slip pattern can facilitate the adjustment of the inner screw ring 15 .
