Hereinafter, with reference to FIGS. 8 and 10 , the operation of the fixing structure 2 for link assembly pin processing and the metal processing device 1 including the same according to another embodiment of the present disclosure will be described.

First, the processor 3 determines whether the link assembly pin (R) is inserted based on the insertion information of the link assembly pin (R) through the detection sensor 52, and determines whether the link assembly pin (R) is inserted. When inserted, the position sensor 53 is activated to determine the position of the contact part 36, and the position of the contact part 36 determined based on the length information of the link assembly pin (R) entered by the user is compared. The position of the contact part 36 can be adjusted through the driving part.

That is, the processor 3 can first determine whether the link assembly pin (R) is inserted through the detection sensor 52 and then sequentially determine the position of the contact portion 36 by activating the position sensor 53. . Afterwards, the processor 3 can automatically fix the link assembly pins (R) having various lengths by adjusting the position of the contact portion 36 through the drive unit based on the length information of the link assembly pins (R). .

For example, in the case of a link assembly pin (R) having a long length, the processor 3 may determine the position of the contact portion 36 based on the length information of the link assembly pin (R) input by the user. By rotating the position control unit 37 in a direction away from the inside of the body 31 through the drive unit, the contact unit 36 is moved in a direction away from the second fixing space S2, thereby forming the link assembly pin (R). It is possible to form a large space to accommodate.

Thereafter, the processor 3 can stably fix the link assembly pin (R) and then rotate the main support portion 10 to process a connection hole (Ra) in the link assembly pin (R).

In addition, the processor 3 determines the protrusion length and support force of the support plate 51 through the gap support portion 61 based on the diameter information of the link assembly pin (R) input by the user, and The rotation speed and rotation time of the main support part 10 are determined based on the diameter information and length information of the link assembly pin (R), and after the position of the contact part 36 is adjusted, the holding part 62 is used with the determined support force. ) can be extended to protrude the support plate 51 to the determined protrusion length of the support plate 51.

That is, the processor 3 protrudes and retracts the support plate 51 in response to the link assembly pins (R) having various diameters as well as the lengths of the various link assembly pins (R) to form the link assembly pins (R). can be fixed.

For example, the processor 3 may protrude the support plate 51 so that the smaller the diameter of the link assembly pin (R) is, the longer the support plate 51 is based on the diameter information of the link assembly pin (R) input by the user. By deciding to extend the length of the holding part 62 with respect to the spacing support part 61 to protrude the support plate 51 inside the support guider 50, the link assembly pin (R) having a small diameter can be stably fixed. can be supported.

At the same time, the processor 3 determines whether the measured pressure difference is within the preset pressure difference based on the pressure information with the link assembly pin (R) measured through the pressure sensor 57, and determines whether the measured pressure difference is within the preset pressure difference. If the pressure difference is exceeded, the rotation speed of the main support part 10 can be reduced and the rotation time can be adjusted to increase.

For example, if the supporting force of the support plate 51 measured through the pressure sensor 57 is different because the outer diameter of the link assembly pin (R) is uneven, the processor 3 exceeds the preset pressure difference. Accordingly, the processor 3 may determine that the diameter of the link assembly pin (R) to be processed is uneven.

Accordingly, by reducing the rotation speed of the main support portion 10 and adjusting the rotation time to be long, processing stability for the uneven link assembly pin (R) can be improved. That is, when machining link assembly pins (R) with uneven diameters at the same speed, vibration may occur due to the deflection center of the link assembly pins (R), thereby preventing stable processing of the connection groove.

Therefore, by reducing the rotation speed of the main support portion 10 and adjusting the rotation time to be long, processing stability for the uneven link assembly pin (R) can be improved.

In addition, the processor 3 forms various protruding lengths of the gripping part 62 supporting the support plate 51, thereby stably contacting link assembly pins (R) having various diameters to assemble the link. The dragon pin (R) can be supported.

Therefore, the fixing structure 2 for link assembly pin processing and the metal processing device 1 including the same according to another embodiment of the present disclosure stably supports the link assembly pins R having various lengths and diameters, The processing stability of the link assembly pin (R) can be greatly improved.
