In the machining process of the traditional turning-milling combined numerical control machine tool, the working process is usually as follows: first, an operator manually clamps the workpiece to be machined into a clamp on the machine tool workbench; after the workpiece is fixed, the machine tool needs to perform a tool setting operation to determine the relative position relationship between the machining reference point of the workpiece and the machine tool coordinate system through a measuring head or a trial cutting; after the tool setting is completed, the numerical control system of the machine tool can drive the tool to perform turning or milling machining according to the preset machining program; after the machining of a single workpiece is completed, the operator needs to manually unload the completed work and clamp the next workpiece to be machined, and then repeat the above tool setting and machining steps.

[0020] By integrating the machine tool, turning-milling, feeding and discharging, cleaning, filtering and feeding six core assemblies, the whole process integration is realized. The machine tool assembly adopts a wrapped design of baffle + door plate, cooperates with the inclined stepped plate of the turning-milling assembly, and reduces the splashing of debris; each assembly is fixedly connected or cooperates with a structure (such as the spacing arrangement of the spindle box and the feeding box), so as to ensure the running stability and lay a foundation for subsequent subdivision function optimization. The design breaks the problem of dispersion and independence of each link of "feeding, feeding and discharging, machining, cleaning and filtering" in traditional turning and milling processing, so that the rod to be processed forms a continuous process from feeding, feeding, turning and milling processing, to discharging after processing, chip cleaning and cutting fluid filtering without interruption. The chips generated by turning and milling processing are intercepted by the wrapping structure and cannot splash outside the machine tool or on the track, making it difficult to clean. At the same time, the inclined step plate guides the chips to the internal filtering assembly, reducing environmental pollution and the workload of cleaning the outside of the machine tool. The feeding and discharging assembly can also clean the filtering component when feeding and discharging the three-jaw chuck, achieving resource saving.

[0021] In this embodiment, the clamping and taking component includes a rotating column 408 and a first spring jaw 409. The top surface of the feeding seat 405 is rotationally connected with the rotating column 408. The surface of the rotating column 408 is fixedly connected with a rotating gear 410.

The first spring jaw 409 is meshingly connected with the rotating gear 410. One side of the first spring jaw 409 is fixedly connected with a first unlocking lever 414.

[0022] Through the meshing cooperation of the rotating column, the rotating gear and the rotating rack, combined with the unlocking / locking function of the first spring jaw, the pneumatic clamp jaw is switched in the direction of 180 degrees rotation. The front extension track drives the pneumatic clamp jaw to extend and retract, which can complete the continuous actions of "machining piece discharging to the feeding assembly" and "taking the piece to be processed from the feeding assembly", improving the coherence of the feeding and discharging process.

[0023] In this embodiment, the receiving component includes an arc block 415. One side of the feeding seat 405 is fixedly connected with the arc block 415.

The bottom surface of the second spring jaw 419 is fixedly connected with a second unlocking lever 420.

[0024] Through the meshing locking of the second spring jaw and the deflection gear, combined with the unlocking action of the first auxiliary unlocking lever, the extension rod can be deflected to one side to avoid.

[0026] The groove structure of the Y-shaped frame can accurately receive the dropped machining parts, ensuring positioning accuracy; the retractable pneumatic rod drives the Y-shaped frame to retract, the inclined smooth groove cooperates with the column rod to realize the action of “first horizontally taking out the workpiece, and then obliquely moving down”, which not only avoids the dropping of the workpiece, but also quickly avoids the subsequent feeding path, improving the feeding and discharging connection speed.
