[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1:

[0023] like Figure 1 、 Figure 2 As shown, an automatic screw locking machine of the present invention comprises a mounting base 1 docking with the output end of the robot, the mounting base 1 is mounted with a three-part plate 2, and the three-part plate 2 is mounted with three sets of screw locking mechanisms 3;

[0024] The screw locking mechanism 3 comprises a base plate 31, the first telescopic cylinder 32 is installed on the base plate 31, the moving plate 33 is connected to the output end of the first telescopic cylinder 32, the positioning sleeve 34 is installed on the moving plate 33, the support 35 is installed on the base plate 31, the second telescopic cylinder 36 is installed on the support 35, the motor seat 37 is installed on the output end of the second telescopic cylinder 36, the motor 38 is installed on the motor seat 37, the motor 38 is signal connected with the torque detection device, and the screwdriver 39 is connected to the output end of the motor 38.

[0025] In the embodiment, when using an automatic screw locking machine, after the workpiece to be processed is installed and fixed in place, the robot operates to drive the three-part plate 2 to move to the set position, and then the screw locking mechanism 3 operates to start screw locking;

[0026] Under the effect of the three-part plate 2, three screws can be locked at the same time, improving the processing efficiency. Further, under this principle, it is not limited to using a three-part plate, but can be a four-part plate, a five-part plate or other plates, so as to realize the installation of multiple screw locking mechanisms 3 and further improve the screw locking efficiency;

[0027] The operation mode of the screw locking mechanism 3 is as follows: the first telescopic cylinder 32 operates to drive the moving plate 33 to move to the position where the screw is to be locked, so that the positioning sleeve 34 is aligned with the threaded hole in which the screw is pre-placed, then the second telescopic cylinder 36 and the motor 38 operate, the operation of the second telescopic cylinder 36 drives the motor seat 37 to start moving, so that the motor 38 installed on the motor seat 37 starts moving towards the threaded hole, and then the screwdriver 39 installed at the end of the motor 38 advances towards the screw in the threaded hole, and after contacting, automatic locking is realized. Moreover, under the effect of the torque detection device, the torque of the motor 38 can be fed back to the connected system in real time, and the torque of the motor 38 can be traced back from the system for the purpose of tracing.

[0028] Embodiment two:

[0032] Embodiment four:

[0033] As shown in Figure 1 , Figure 2 , the first spring 314 is sleeved on the output shaft of the second telescopic cylinder 36, so that the purpose of buffering is achieved.

[0034] In the embodiment, the first spring 314 also has an effect of assisting the second telescopic cylinder 36 to return, so that the second telescopic cylinder 36 returns faster, and the purpose of accelerating the production efficiency is achieved.
