Fig. 1 is a schematic structural diagram 1 of an embodiment of the present invention.

Fig. 2 is a schematic structural diagram 2 of an embodiment of the present invention.

FIG. 3 is a state diagram illustrating the use of the embodiment of the present invention;

in the figure: 1. a mechanical arm fixing end; 2. a cable fixing end; 3. a hexagonal counter bore is arranged in the arm end; 4. hexagonal counter bores are formed in the end terminals; 5. a circular hole at the end of the wire; 6. a circular hole at the arm end; 7. a cylindrical counter bore at the end of the wire; 8. a cylindrical counter bore at the arm end; 9. a cylindrical head bolt; 10. a hexagonal nut; 11. a cable; 12. and a mechanical arm.

Detailed description of the preferred embodiments.

As shown in fig. 1 and fig. 2, the manipulator arm cable fixing device of the present embodiment includes a manipulator arm fixing end 1 and a cable fixing end 2, wherein the manipulator arm fixing end 1 is provided with an arm end circular hole 6, an arm end hexagon socket counterbore 3 and an arm end cylindrical counterbore 8; the cable fixing end 2 is provided with a wire end circular hole 5, a wire end inner hexagonal counter bore 4 and a wire end cylindrical counter bore 7.

As shown in fig. 3, the two legs at the arm end of the arm cable fixing device are bent at a certain angle and placed on the mechanical arm 12, so that the circular hole 6 at the arm end is attached to the mechanical arm 12, and then the cable 11 to be fixed passes through the circular hole 5 at the wire end. Further put into arm end hexagon socket head cap counter bore 3 and terminal end hexagon socket head cap counter bore 4 respectively with 2 hexagon nuts 10, insert 2 cylinder head bolts 9 respectively from terminal end cylinder counter bore 7 and 8 departments of arm end cylinder counter bore to screw in corresponds hexagon nut 10 and screw up, can realize fixing the cable. Otherwise, the cylindrical head bolt 9 is loosened reversely and taken out, and the two legs at the arm end of the cable fixing device are broken by a certain angle, so that the cable fixing device can be taken out.

Preferably, when the cable fixing device is fixed to the robot arm through the hexagon socket head cap screw 9 and the hexagon nut 10 at the opening side of the robot arm cable fixing device, the cable fixing device structure itself allows a certain degree of deformation, and the position is not strictly locked, so that the position can be adjusted by axial movement.

The preferred end of wire hexagon socket counterbore 4 and end of wire cylinder counterbore 7 are located between the end of wire circular bore 5 and the arm end circular bore 6. When the hexagon socket head hole 4 and the end terminal cylindrical counterbore 7 are not fixed through the cylindrical head bolt 9 and the hexagon nut 10, the end terminal circular hole 5 can enable the cable 11 to smoothly pass through. On the contrary, in the process of fastening the stud bolt 9 and the hexagon nut 10, the wire end circular hole 5 and the arm end circular hole 6 are deformed by stress and reduced, and the cable fixing device and the cable 11 are fastened to the robot arm.

Optionally, the cable fixing of the mechanical arms with different specifications can be realized by changing the suitable hole diameters of the wire end circular hole 5 and the arm end circular hole 6 and the number and distribution of the mechanical arm cable fixing devices.

To sum up, the manipulator cable fixing device of this embodiment is simple in structure, small in occupied space, low in manufacturing cost and convenient to install. In the motion process of the existing mechanical arm, the cable can synchronously move along with the mechanical arm, and the mechanical arm is suitable for automatic work of the mechanical arm.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
