[0023] Embodiment
[0024] As Figures 1-5As shown in the figure, a joint arm loading device includes a pneumatic rotary cylinder 1. A rotary shaft 10 is connected to the driving end of the pneumatic rotary cylinder 1. A striker 2 and a transmission shaft A 18 are respectively connected to both ends of the rotary shaft 10. A rotary arm 20 is connected to the end of the transmission shaft A 18 away from the rotary shaft 10. A transmission shaft B 8 is provided on the rotary arm 20, and a loading box 9 is connected to the transmission shaft B 8.
[0025] A switch 12 is provided at the upper end of the striker 2. The switch 12 is fixedly connected through a bracket 11. A positioning rod 14 and a bracket 2 are also provided at the connection between the rotary shaft 10 and the transmission shaft A 18. The positioning rod 14 is arranged between the transmission shaft A 18 and the rotary shaft 10. After the positioning rod 14 rotates through the rotary shaft 10, it drives the striker 2 to control the opening or closing of the switch 12. When the switch 12 is opened or closed, it can drive the positioning rod 14 to control the stopping of the transmission shaft A 18. Oil-impregnated bearings 16 and 19 are respectively sleeved on the front and rear ends of the transmission shaft A 18. A sleeve 15 is sleeved on the oil-impregnated bearing 16. A dust-proof ring 17 is provided between the sleeve 15 and the transmission shaft A 18. The positioning rod 14 is fixedly connected to the sleeve 15 through a fixing plate 13. The transmission shaft A 18 realizes stable rotation by using the oil-impregnated bearings 16 and 19 and is connected to the rotary arm 20.
[0026] The upper and lower ends of the rotary arm 20 are respectively rotatably connected to the transmission shaft A 18 and the transmission shaft B 8. The rotary arm 20 rotates with the rotation of the transmission shaft A 18. A pulley A 21 and a pulley B 5 are provided inside the rotary arm 20. An idler pulley 23 is provided between the pulley A 21 and the pulley B 5. The pulley A 21, the pulley B 5 and the idler pulley 23 are connected by a timing belt 22. The pulley A 21 and the pulley B 5 are respectively connected to the transmission shaft A 18 and the transmission shaft B 8. An idler pulley shaft 24 rotatably connected thereto is provided inside the idler pulley 23. The idler pulley shaft 24 is fixedly connected to the rotary arm 20. After the transmission shaft A 18 drives the rotary arm 20 to rotate, the pulley A 21 and the pulley B 5 are simultaneously driven to rotate through the timing belt 22, so as to achieve the purpose of simultaneously driving the transmission shaft B 8. A spacer ring 1 and a spacer ring 2 are sleeved on the transmission shaft B 8. The spacer ring 1 and the spacer ring 2 are respectively located on both sides of the pulley B 5. A sleeve 2 is also provided between the transmission shaft B 8 and the rotary arm 20. After the transmission shaft B 5 is connected by the pulley, it rotates in the same direction as the transmission shaft A 18, driving the connected loading box 9 to perform a flipping motion.
[0027] In the present utility model, the transmission shaft A18 and the transmission shaft B5 are connected by a pulley structure to achieve synchronous rotation. One end of the transmission shaft A18 is connected to the rotating shaft 10, and the striker 2 is driven by the rotating shaft 10 to control the opening and closing of the switch 12. The switch 12 controls the positioning rod 14 to control the rotation or stop of the transmission shaft A18. The rotating shaft 10 is driven by the pneumatic rotary cylinder 1. When the transmission shaft B5 rotates, the material receiving box 9 provided on the transmission shaft B5 can perform the operation of flipping and receiving materials. The two-axis joint structure moves simultaneously, and the two axes have their respective rotation angles. When the rotating arm 20 rotates clockwise to the 90-degree position, the material receiving box 9 is linked with the transmission shaft B5 and rotates 180 degrees by itself to reach the material receiving position, reducing the movement trajectory of the material receiving box 9 and avoiding an overly long parabola, which can ensure that the bar stock does not fall stably.
