[0025] A kind of automatic assembly device of pulley of tensioner, as shown in Figure 1 Including workbench 1 and automatic screw tightening device 2, automatic screw tightening device 2 is set on the table top of workbench 1. Workbench 1 provides the required basis for installing other devices, and automatic screw tightening device 2 realizes automatic tightening screw of tensioner.

[0026] As shown in Figure 1 Workbench 1 is rotatably connected with turntable 11, and the carrier table is arranged on the turntable 11. The carrier table is uniformly arranged along the circumference of the turntable 11. During work, the carrier table carries the tensioner to be assembled, and the turntable 11 rotates to send the carrier table into different stations.

[0027] As shown in Figure 1 And Figure 2 The automatic screw tightening device 2 of the automatic assembly device of pulley of tensioner further includes an automatic screw tightening device 2, which is arranged on the table top of the workbench 1. The automatic screw tightening device 2 tightens the screw of the tensioner to be assembled.

[0028] As shown in Figure 1 And Figure 2 The automatic screw tightening device 2 includes a mounting frame 21 and a tightening manipulator 24, and the tightening manipulator 24 is installed on the mounting frame 21 and performs lifting motion. During work, the tightening manipulator 24 is lowered to tighten the screw into the tensioner.

[0029] As shown in Figure 2As shown, the mounting bracket 21 is fixed to the surface of the workbench 1 and is located outside the turntable 11. A lead screw 211 is rotatably connected to the mounting bracket 21, and the lead screw 211 is arranged vertically. A motor 212 is mounted on the top of the mounting bracket 21, and the motor 212 is connected to the lead screw 211. During operation, the motor starts, driving the lead screw 211 to rotate forward or backward.

[0030] like Figure 2 As shown, the mounting frame 21 is movably equipped with a liftable threaded rod nut 22, which is threadedly engaged with the lead screw 211. A fixing plate 23 is mounted on the threaded rod nut 22, and the fixing plate 23 is horizontally arranged. A tightening robot 24 is mounted on the fixing plate 23.
