Specific embodiment
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to the utility model
Work more comprehensively, meticulously describes, but the protection scope of the utility model is not limited to embodiment in detail below.
As shown in Fig. 1-Fig. 3, a kind of dual robot bolt automatic tightening system being arranged symmetrically of the present embodiment, including
It is two multi-axis robots, 1, two walking track 2, automatic tool change station 3, vision positioning system 4, servo tightening tool 5, total
Control system.For two multi-axis robots 1 in being arranged symmetrically on two walking tracks 2 setting up and down up and down, robot 1 can
It is moved along walking track 2, the automatic tool change station 3 is arranged in walking 2 end of track.
As shown in Fig. 2, it has been fixed by the bracket vision positioning system 4 and servo tightening tool 5 in the end of robot 1,
The vision positioning system 4 includes 3D camera；The servo tightening tool 5 includes servo motor 51, speed reducer 52, shaft coupling 54
With torque sensor 53,51 output shaft of servo motor is connected with 52 input shaft of speed reducer, shaft coupling 54 and 52 output shaft of speed reducer
Be connected, shaft coupling 54 for picking up and driving bolt collar, the setting of torque sensor 53 shaft coupling 54 and speed reducer 52 it
Between.
As shown in figure 3, the automatic tool change station 3 includes Working gantry 31, servo turntable 32, receiver 33, it is more
A receiver 33 is evenly arranged on the circumference of 32 end face of servo turntable, can place the spiral shell of different size on receiver 33 respectively
Bolt sleeve, laying is had vacant position detection sensor on receiver 33, and servo turntable 32 is fixed on Working gantry 31, can will be right
It answers the bolt collar of specification to rotate to robot and picks up station.
The operation at the turn-key system control robot and automatic tool change station.Turn-key system controls Liang Tai robot 1
