In the automatic feeding and discharging processing equipment, automatic feeding, clamping of the workpiece 101, loosening of the workpiece 101 and automatic discharging are realized to achieve the automatic feeding and discharging function, manual tightening of workers is not required, and the labor intensity of workers is reduced, the production efficiency is improved, and the yield is improved.

[0046] Specifically, referring to Figure 7 、 Figure 8 and Figure 9 , the first pivot shaft 117 is inserted into the clamping arm 113, and the clamping arm 113 rotates about the central axis of the first pivot shaft 117. It can be understood that the first pivot shaft 117 is close to the first end 1131, so that the pivot center axis of the clamping arm 113 is close to the first end 1131, so that the pivot center axis of the clamping arm 113 is away from the first elastic member 114, that is, the clamping force of the first end 1131 clamping the workpiece 101 is improved by increasing the vertical arm for pushing the clamping arm 113 to rotate the first elastic member 114, and the stability of clamping is effectively improved.

[0047] It can be understood that the body 111 is provided with a clamping piece 116, and the clamping piece 116 has a cavity 1161 for accommodating the workpiece 101. When the workpiece 101 is clamped, the two side inner walls of the cavity 1161 press against the two side outer walls of the workpiece 101. When the first elastic piece 114 pushes the clamping arm 113 to rotate, the first end 1131 of the clamping arm 113 can push the clamping piece 116 to deform, thereby clamping the workpiece 101. Specifically, the clamping piece 116 includes an elastic part 1162. When the first end 1131 pushes the clamping piece 116, the elastic part 1162 can be elastically deformed. When the first end 1131 leaves the clamping piece 116, the elastic part 1162 can be elastically reset, thereby releasing the workpiece 101. Further, the clamping piece 116 is provided with a hollow part 1163 located below the workpiece 101 and communicating with the cavity 1161. By providing the hollow part 1163, the elastic part 1162 can be elastically deformed, thereby clamping and releasing the workpiece 101.

When the pulling cylinder 121 is started and pulls the pushing block 122, the pushing block 122 rotates, and the pressing end 124 presses the second end 1132 of the clamping arm 113, so that the clamping arm 113 rotates and the first end 1131 leaves the clamping piece 116, thereby realizing the opening process. When the piston rod of the pulling cylinder 121 is extended to push the pulling end 125 and drive the pushing block 122 to rotate, the pressing end 124 leaves the second end 1132, so that the clamping arm 113 can be reset under the driving of the first elastic member 114, thereby realizing the clamping of the workpiece 101.

[0051] It can be understood that the second pivot shaft 123 is close to the pressing end 124, so that the distance between the pivot center axis of the pushing block 122 and the pressing end 124 is less than the distance between the pivot center axis of the pushing block 122 and the pulling end 125, thereby increasing the rotating torque by increasing the vertical arm driven by the pushing block 122 to rotate, so that the pushing block 122 can smoothly drive the clamping arm 113 to rotate, which is beneficial to improve the efficiency.
