The bottom of the first spring 610 is connected to the top of the external rod 400, and the top of the first spring 610 is connected to the top inside the internal rod 600. When the pressure rod 700 moves downward, the internal rod 600 also moves downward.

[0026] In a possible implementation manner, a second spring 320 is provided at the bottom of the telescopic hexagonal tenon 300. The second spring 320 is used to reset the telescopic hexagonal tenon 300.

[0027] Specifically, asFigure 1 As shown, in order to enable the telescopic hexagonal tenon 300 to receive pressure and release pressure, a second spring 320 is provided at the bottom of the telescopic hexagonal tenon 300. When the external rod 400 moves downward, the second spring 320 is compressed. Then, when the external rod 400 moves upward, the second spring 320 returns to its original state, releasing pressure and causing the telescopic hexagonal tenon 300 to return to its original position.

[0028] In a possible implementation, the telescopic group further includes a housing and a bearing; the housing is a hollow structure, the housing is arranged on the top of the base, and the lower parts of the external rod 400, the pressure rod 500, and the internal rod 600 are all arranged inside the housing; the bearing is arranged between the housing and the internal rod 600 and is located at the upper part of the housing; a limit plug 310 is arranged at the lower position inside the housing, and the telescopic hexagonal tenon 300 stops rotating when it touches the limit plug 310 during rotation.

[0029] Specifically, as Figure 1 shown, in order to limit the rising height, a limit plug 310 is provided. The limit plug 310 is arranged at the lower position inside the housing and has a preset distance from the telescopic hexagonal tenon 300. The telescopic hexagonal tenon 300 stops rotating when it touches the limit plug 310 during rotation.

[0030] In a possible implementation, the pressure rod 500 has a "T" - shaped structure. The upper part of the pressure rod 500 extends to both sides and coincides with the outer edge of the bottom of the internal rod 600.

[0031] Specifically, as Figure 1 shown, the pressure rod 500 has a "T" - shaped structure. The upper part of the pressure rod 500 extends to both sides and coincides with the outer edge of the bottom of the internal rod 600, so that the internal rod 600 can transmit pressure to the pressure rod 500, and the pressure rod 500 moves downward, driving the external rod 400 to move downward.

[0032] In a possible implementation, the tightening group includes a coupling shaft 810 and a sleeve 820; the coupling shaft 810 is arranged inside the sleeve 820, the bottom of the coupling shaft 810 is connected to the pressure rod 700, an external nut is arranged on the top of the coupling shaft 810, and an external bolt passes through the external nut and is inserted into the top of the coupling shaft 810.

[0033] Specifically, as Figure 1 shown, the external nut is placed inside the sleeve 820 on the top of the coupling shaft 810. The external bolt passes through the external nut and is inserted into the top of the coupling shaft 810. When the telescopic hexagonal tenon 300 moves up and down and rotates, it drives the coupling shaft 810 to move up and down and rotate, enabling tightening between the external bolt and the external nut.

[0034] In a possible implementation, the top of the shaft coupling 810 is lower than the top of the sleeve; with such a setting, it can be achieved that both the external bolt and the external nut are inside the sleeve 820, avoiding the situation where the external bolt and the external nut fall off during tightening.

[0035] In a possible implementation, it further includes a fixing plate 900. The base 100 is arranged on the fixing plate 900, and a tightening gun 910 is arranged on one side of the fixing plate 900. The tightening gun 910 is connected to one of the gears 200.

[0038] Specifically, two telescopic cylinders 920 are set to apply pressure to the pressure rod 700, causing the pressure rod 700 to move downward. After the inner connecting rod 600 senses the pressure, it then moves downward. The inner connecting rod 600 transmits the pressure to the pressure lever 500, and the pressure lever 500 drives the outer connecting rod 400 to move downward. The outer connecting rod 400 transmits the pressure to the telescopic hexagonal tenon 300, and the telescopic hexagonal tenon 300 rotates and moves downward.

[0039] When this application is used, the base 100 is installed above the fixing plate 900, and the tightening gun is installed on one side of the fixing plate 910, so that the tightening gun 910 is connected to the gear 200 inside the base 100. The telescopic cylinder 920 on the fixing plate 900 is connected to the pressure rod 700 to drive the pressure rod 700 to move up and down. The external bolt and the external nut are placed inside the sleeve 820. The tightening gun 910 controls the gear 200, and the telescopic cylinder 920 controls the two pressure rods 700 to move up and down, realizing the tightening component.

[0040] This application is provided with a base 100, a gear 200, a telescopic hexagonal tenon 300, an external connecting rod 400, a pressing rod 500, an internal connecting rod 600, a pressure rod 700 and a tightening group.

The two telescopic groups are connected together through the gear 200, and the two telescopic groups are controlled by the gear 200. The number of telescopic hexagonal tenons 300 is two, which are respectively arranged in the gears 200 on both sides. The telescopic hexagonal tenon 300 rotates to achieve tightening. When pressure is applied to and released from the telescopic hexagonal tenon 300, the telescopic hexagonal tenon 300 starts to rotate. The external connecting rod 400 is arranged above the telescopic hexagonal tenon 300. A first through hole is provided at the bottom of the external connecting rod 400, and a second through hole is provided near the lower part of the external connecting rod 400. The pressing rod 500 is arranged in the second through hole. The pressing rod 500 can pass through the first through hole and be connected to the telescopic hexagonal tenon 300. Such an arrangement enables the telescopic hexagonal tenon 300 to drive the pressing rod 500 to move up and down and rotate, and the pressing rod 500 drives the external connecting rod 400 to move up and down and rotate. The internal connecting rod 600 is a hollow long strip structure. The upper part of the external connecting rod 400 is inserted into the internal connecting rod 600 and can move up and down inside the internal connecting rod 600. The pressure rod 700 is connected to the internal connecting rod 600. The pressure rod 700 can move up and down and rotate to apply pressure to the telescopic hexagonal tenon 300.

[0041] Through the above arrangement of this application, the two telescopic groups work simultaneously and cooperate alternately, one up and one down, to increase the tightening frequency and improve work efficiency, solving the problem that when the tightening method of single-piece picking by a robot cannot meet the beat requirements when the production beat is relatively high, resulting in low production efficiency.
