Based on the arrangement rule of the placement holes 302, a plurality of rows may be provided, wherein each row of placement holes 302 corresponds to one set of locking mechanisms.
In addition, in another alternative embodiment of the present invention, a detection switch 305 is disposed in the placement hole 302, and the detection switch 305 is used for detecting the condition of the sleeve 106 in the placement hole 302. For example, when the detection switch 305 detects that the sleeve 106 is present in the corresponding placement hole 302, the detection switch 305 turns on, and when the detection switch 305 detects that the sleeve 106 is not present in the corresponding placement hole 302, the detection switch 305 turns off. The detection switch 305 may be electrically connected to a control module of the robot 200 and a control module of the unlocking mechanism 303. The detection switch 305 may be a sensor, a limit switch, or the like.
According to the tightening shaft replacing device 100 provided by the invention, two groups of tightening shaft assemblies are arranged on the bracket 120, each group of tightening shaft assemblies are automatically connected through the first quick-change piece 103 and the execution end of the robot 200, the tightening shafts 101 of each group of tightening shaft assemblies are different, the robot 200 is automatically matched with different tightening shafts 101 to be replaced according to requirements by forming different tightening shaft assemblies by the first quick-change piece 103 and different tightening shafts 101, and the working efficiency is improved.
Further, the tightening shaft exchanging device 100 according to the present invention has various advantages as described above.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
