[0019] The utility model is further described below in connection with the drawings and examples.

[0020] Example 1

[0021] As Figures 1-3 Shown, the utility model discloses a servo motor 1-1, the speed reducer 1-2 that is connected with servo motor 1-1, the drive shaft 1-4 that is connected with speed reducer 1-2 are set from top to bottom in proper order, and thus, through the operation of speed reducer 1-2 and servo motor 1-1 drive shaft 1-4 is rotated;

[0022] In the embodiment, servo motor 1-1 and speed reducer 1-2 adopt the hoop type connection, to eliminate the clearance of servo motor 1-1 and speed reducer 1-2.

[0023] Drive shaft 1-4 is connected with rotary arm 1-6 through key 1-9, to make rotary arm 1-6 synchronous rotation with drive shaft through the operation of drive shaft 1-4 through key 1-9, in the embodiment, the one end of rotary arm 1-6 away from drive shaft 1-4 is connected with mechanical hand claw assembly 1-13.

[0024] The upper and lower ends of the rotary arm 1-6 and the driving shaft 1-4 are provided with upper and lower pressure covers 1-5 and 1-8, and the ends of the upper and lower pressure covers 1-5 and 1-8 away from the rotary arm 1-6 are connected with a guide frame 1-3, so that the rotary arm 1-6 is limited in position on the driving shaft 1-4 through the guide frame 1-3 as a fixed point and through the upper and lower pressure covers 1-5 and 1-8.

[0025] The upper and lower pressure covers 1-5 and 1-8 are connected with the driving shaft 1-4 through bearings 1-7, so that the upper and lower pressure covers 1-5 and 1-8 are fixed with the guide frame 1-3.

[0026] The bearings 1-7 are provided with gap adjusting shims 1-11 between the upper and lower pressure covers 1-5 and 1-8, and in the embodiment, the bearings 1-7 are conical roller bearings, so that the gap between the bearings 1-7 and the upper and lower pressure covers 1-5 and 1-8 is adjusted through the gap adjusting shims 1-1.

[0027] The upper end of the rotary arm 1-6 is connected with a proximity switch 1-12 at one end of the upper pressure cover 1-5, so that when the rotary arm 1-6 rotates, the proximity switch 1-12 ensures that the rotary arm can be lifted only when the mechanical hand is in the turning-out position, thereby ensuring safety.

[0028] The end of the rotary arm 1-6 facing the driving shaft 1-4 is semi-open, the driving shaft 1-4 is sleeved in the semi-open rotary arm 1-6, and the semi-open rotary arm 1-6 fixes the driving shaft 1-4 in the rotary arm 1-6 through fastening bolts 1-10.

[0029] In one embodiment, the servo motor 1-1 comprises a high-precision encoder and a servo controller.

[0030] Therefore, the servo motor 1-1 of the utility model adopts a high-precision encoder and a servo controller, and the rotary arm 1-6 is accurately stopped at different stations through program adjustment of angle parameters. After each replacement of the mold, the accuracy of the mechanical hand is re-confirmed, and the parameters can be adjusted on the control panel, without manual adjustment of the mechanical limiting device, so that working hours can be saved and efficiency can be improved.

[0031] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the technical solutions of the utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
