When the numerical control machine tool with the limiting protection structure is required to be used, the working principle is as follows:
normal processing:
firstly, a user can install and fix a milling machine fixture through a gully of a discharging platform 7, then clamp and fix a workpiece at the fixture, in the using process, the user can close a box cover 13 through a handle 9 and operate at a control panel 11, the left-right movement and the front-back movement of the discharging platform 7 can be controlled through the positive and negative rotations of an X-axis motor 402 and a Y-axis motor 302 through an X-axis screw 405 and a Y-axis screw 303, the height adjustment of a milling cutter structure 201 can be controlled through the positive and negative rotations of a Z-axis motor 202, after the corresponding height is reached, the power inside the milling cutter structure 201 is started to enable the milling cutter to rotate, and then the milling processing of the workpiece can be completed through the left-right movement and the front-back movement of the discharging platform 7.
Limit protection processing:
in the process of processing, a user needs to continuously complete workpiece replacement at the discharging platform 7, and at the moment, the workpiece replacement needs to be performed by continuously stopping and opening the box cover 13, so that the situation that an operator is injured due to out-of-control of the milling cutter structure 201 caused by misoperation or system errors in the workpiece replacement process is likely to occur, therefore, the limit protection structure is designed, that is, before the box cover 13 is opened to replace the workpiece, the control panel 11 is used for controlling the output shaft of the hydraulic cylinder 15 to extend out of the box, so that the hydraulic cylinder 15 can push the discharging platform 7 to move upwards, at the moment, the discharging platform 7 can drive the gear 19 to rotate through the vertical rack 16, meanwhile, the gear 19 drives the transverse rack 21 to drive the friction plate 17 to move, the friction plate 17 is tightly attached to the right end of the friction sleeve 18, the rotation of the friction sleeve 18 and the rotating shaft 505 is limited, because the rotation of the rotation shaft 505 is limited through the coupling assembly 5 and the Z-axis screw 207, the rotation of the rotation shaft 505 is limited, namely, the rotation of the Z-axis screw 207 is limited, the fact that the Z-axis screw 207 cannot rotate is guaranteed, the milling cutter structure 201 cannot change in height is guaranteed, even if the milling cutter structure 201 is out of control, the milling cutter structure 201 cannot move down to cause injury to an operator at a specific height, sufficient time is reserved for the operator when misoperation or system error occurs, the problem that the operator hurts people due to the milling cutter structure 201 due to misoperation or system error is avoided when the workpiece is replaced without stopping is solved, after the workpiece is replaced, the box cover 13 is closed, the discharging platform 7 is controlled to move downwards to reset through the hydraulic cylinder 15, and the rotation limiting between the friction plate 17 and the friction sleeve 18 can be released, so that the rotation capacity of the Z-axis screw 207 can be restored.
Transmission of the coupling assembly:
