The moving component is installed on the lower end surface of the work box. A screw pipe is rotatably provided between the corresponding first shaft seat and the second shaft seat. The driving component is installed inside the work box. The upper end of the screw rod passes through the lower end surface of the work box, and multiple groups of screw rods are respectively threadedly connected with multiple groups of screw pipes. The square ring plate is fixedly installed at the lower ends of the multiple groups of screw rods. The chip removal component is installed on the upper end surface of the work box, and the inclined-rail double-spindle turning and milling compound machining center body is installed on the chip removal component;

[0004] When this structure is in use, multiple groups of first bevel gears drive multiple groups of screw pipes to rotate respectively, so that multiple groups of screw rods drive the square ring plate to move downward. When the square ring plate contacts and presses against the ground, under the connection action of the first shaft seat and the second shaft seat, the work box moves upward. At this time, the moving wheels are separated from the ground. Under the connection action of the collection box and the support plate, the working height of the inclined-rail double-spindle turning and milling compound machining center body is adjusted. However, this structure is not easy to meet the multi-angle and range machining requirements of workpieces during use, and it is not easy to achieve the function of comprehensively machining the outer side of workpieces, and it is not convenient enough during use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a double-spindle turning and milling compound machining center, aiming to solve the problems proposed in the above background art.

[0006] The present invention provides the following technical solutions: A double-spindle turning and milling compound machining center, including a protective shell, and a machining component is arranged on the protective shell;

[0007] The processing assembly includes a base disposed within the protective housing. One end of the base is mounted with a first limit seat through bolts, and a second limit seat with adjustable position is disposed on one side of the first limit seat;

[0008] On one side of the top of the base, there is a slidable seat with adjustable position. An enhancement frame with adjustable position is arranged on the slidable seat. A processing disk is rotatably connected to one side of the enhancement frame. A plurality of mounting holes are penetrated through the processing disk, and inner bushings for milling cutter limit are arranged in each of the mounting holes. Limit slots for clamping the milling cutter are opened on both sides of the surface of each mounting hole. An installation plate is mounted on one side of the processing disk through bolts. A plurality of marks are distributed on the installation plate, and each of the marks is located on one side of the corresponding mounting hole. The first limit seat and the second limit seat are arranged oppositely and are on the same axis line. Chucks for clamping the workpiece are arranged at one ends of the first limit seat and the second limit seat;

[0009] It can be seen that in the above technical solution, the workpiece is placed between the second limit seat and the first limit seat and is respectively clamped at both ends of the workpiece by each chuck, which is conducive to workpiece positioning to ensure the stability of the workpiece during processing. At the same time, the positions of the slidable seat, the enhancement frame, and the processing disk are adjusted by the second lead screw drive module. The enhancement frame is driven by the third lead screw drive module to drive the processing disk to displace on the slidable seat, so that the processing disk can approach the workpiece.

[0011] It can be seen that in the above technical solution, the second pulley is driven to rotate by the driving motor, and the first pulley is driven to rotate by the reinforced belt. When the first pulley rotates, it drives the worm to rotate, and the worm is meshed with the worm wheel, and then the worm wheel drives the second transmission shaft to rotate, and then the processing disk drives the milling cutter to rotate to process the workpiece. At the same time, the self-locking of the worm and the worm wheel can effectively prevent the worm wheel from rotating. At the same time, when the milling cutter is installed in the mounting hole, it is convenient to mark and calibrate the milling cutter during installation to ensure the accuracy of the milling cutter installation.

[0016] 4. In the present invention, the first pulley is driven to rotate by the reinforcing belt. When the first pulley rotates, the worm is driven to rotate. The worm meshes with the worm gear, and then the worm gear drives the second transmission shaft to rotate. Then the processing disc drives the milling cutter to rotate to process the workpiece. At the same time, due to the self-locking of the worm and the worm gear, the phenomenon that the worm gear rotates back can be effectively avoided. At the same time, when the milling cutter is installed in the installation hole, it is convenient to calibrate the installation of the milling cutter through the marking to ensure the accuracy during the installation of the milling cutter;

[0017] In summary, through the corresponding cooperation of each structure, each chuck clamps the two ends of the workpiece respectively, which is easy to position the workpiece to ensure the stability of the workpiece during processing.
