Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a forearm component of an industrial robot. Background Art

[0002] Industrial robots are usually auxiliary devices that assist workers in moving or processing objects.

[0003] An industrial robot is generally composed of a base, a support column, a forearm, a control box and a gripper. The parts that make up the forearm include an arm rod, a transmission line and the like. When installing the transmission line of the forearm, the transmission line is usually connected to the arm rod and the control box, and the exposed transmission line is then tied and fixed with a cable tie.

[0004] When the transmission lines in the forearm assembly are bundled and fixed by cable ties, on the one hand, when the transmission lines are subsequently inspected and repaired, the cable ties need to be cut off, and new cable ties need to be used for bundling after the inspection and repair; on the other hand, multiple groups of transmission lines are bundled together. Since the function of the transmission lines is to transmit electric energy, a part of heat will be generated when the electric energy is transmitted in the transmission lines. After the transmission lines are bundled together, the heat is not easy to dissipate, which makes it easy for the transmission lines to age faster due to being in a high temperature environment for a long time. In view of the above problems, the inventor proposes a forearm assembly of an industrial robot to solve the above problems. Utility Model Content

[0028] By adopting the above technical solution, after the transmission line 3 is fitted with the fixed block 6, the transmission line 3 pushes the plug plate 15 and the second limit block 16 in the opposite direction through the obstruction of the fixed block 6, so that the plug plate 15 is inserted into the fixed plate 14 under the limit of the second limit block 16 to compress the first limit block 117.

[0029] The clamping unit includes a rubber pad 18 and a clamping plate 19 , and the middle end of the inserting plate 15 away from the fixing plate 14 is fixedly connected to the rubber pad 18 , and the two ends of the inserting plate 15 away from the fixing plate 14 are fixedly connected to the clamping plate 19 .

[0035] Working principle: when installing the transmission line 3, first connect the transmission line 3 with the gripper 2 and the chassis, and then turn the screw disk 8 to make the screw disk 8 drive the external threaded rod 7 to rotate. After the external threaded rod 7 rotates, it engages with the thread of the fixed block 6, so that the external threaded rod 7 drives the baffle 9 to move under the limit of the limit plate 10 and the first limit block 11. When the first limit block 11 moves, it drives the roller 12 and the limit rod 13 to move, so that the roller 12 rolls against the inner wall of the fixed block 6 under the limit of the limit rod 13, and the rolling of the roller 12 assists the movement of the baffle 9. When the baffle 9 moves to a certain distance, stop turning the screw disk 8, and then A plurality of transmission lines 3 are inserted into the card plate 19, and then the screw disk 8 is screwed in the reverse direction, so that the external threaded rod 7 rotates in the reverse direction to drive the baffle 9 to return. In the process of returning the baffle 9, the fixed plate 14, the plug plate 15, the rubber pad 18 and the second limit block 16 are driven to squeeze the transmission line 3. When the transmission line 3 is fitted with the fixed block 6, the transmission line 3 is squeezed and pushes the plug plate 15 in the reverse direction, so that the plug plate 15 is inserted under the limit of the second limit block 16 with the compression spring 17 in the fixed plate 14. When the baffle 9 is reset, stop screwing the screw disk 8, and fix the transmission line 3 by the elastic potential energy of the spring 17, the rubber pad 18 and the card plate 19.
