Turning is a lathe process, primarily used for machining workpieces with rotating surfaces such as shafts, disks, and sleeves. During the turning process, the workpiece rotates, while the turning tool moves in a straight line or curve within a plane for cutting. Turning can be divided into rough turning and fine turning. Rough turning pursues efficiency, while fine turning focuses on machining accuracy and surface quality.

The moving control component includes a sliding base installed on the top of the machine tool body. This invention, through the mounting base at the bottom end of the movable spindle part and each Each slide rail is connected by three sliding blocks to ensure that the cutting rigidity is sufficient, and the moving accuracy of the movable spindle is more stable and the efficiency is higher. At the same time, the bed adopts a flat bed and an inclined saddle, which can effectively release the stress caused by cutting and improve the cutting processing effect of the machine tool. This technical solution still has some shortcomings in the process of application.

A driving wheel B is sleeved on the torsional shaft of the workpiece rotating mechanism, and the same driven belt B is sleeved between the driving wheel B and the driving wheel A.
[0026] A method for using a high-stability turning machine tool, comprising:
[0027] S1: First, the workpiece to be turned is clamped and connected to the workpiece rotating mechanism, and the built-in control system of the turning machine is started. On the one hand, the control system controls the workpiece rotating mechanism to drive the workpiece to be turned to rotate quickly and uniformly. On the other hand, the control system controls the turning mechanism to drive the tool to operate to process the rotating workpiece to produce a spherical workpiece;
[0028] S2: The built-in torsion shaft of the workpiece rotation mechanism drives the workpiece fixture to rotate rapidly, and also drives the driving wheel B to rotate. The driving wheel B drives the driven wheel B to rotate through the transmission belt B. During the rotation process, the driven wheel drives the transmission rod to rotate through the transmission sleeve. The other end of the transmission rod applies the torsion force on the torsion shaft to the support sleeve through the driving wheel A, transmission belt A and driven wheel A. The support sleeve rotates under the drive of the torsion force.
[0029] S3: When more than half of the turning process of the spherical workpiece is completed, the control system controls the motor to operate, and the motor drives the threaded rod to rotate. During the rotation of the threaded rod in the threaded barrel, the threaded barrel will drive the track seat to slide on the slide rail through the side connecting plate toward the spherical workpiece. During this process, the track seat drives the transmission rod to retract in the transmission sleeve through the wheel frame A. Under the action of the transmission assembly, the support sleeve and the workpiece to be turned, which are clamped and connected by the workpiece rotating mechanism, rotate synchronously;
[0030] S4: When the multiple spherical connection components are pushed to the spherical workpiece, the control system controls the hydraulic cylinder to perform a retraction movement, and the hydraulic cylinder drives the multiple adapter frames B to move synchronously through the driving disk. During the movement of the adapter frame B, the end of the driving rod will rotate inside, and the other end of the driving rod will apply an upward thrust to the end of the telescopic head. When the telescopic head is subjected to the upward thrust, on the one hand, it will drive the tooth surface telescopic rod B to perform an extension movement in the adapter sleeve, and on the other hand, it will drive the adapter sleeve to rotate inside the adapter frame B. The tooth surface telescopic rod A performs an extension movement in the adapter sleeve, which will drive the transmission gear to rotate. The transmission gear drives the tooth surface telescopic rod A to perform an extension movement in the adapter sleeve. During this process, the tooth surface telescopic rod A slides on the slider A through the slide groove A, and causes the support spring A to undergo elastic deformation. The other end of the tooth surface telescopic rod A drives the spherical connection component to approach the spherical workpiece;
[0031] S5: When the track seat moves toward the spherical workpiece on the slide rail, the piston plate will be pulled by the piston rod. The piston plate will squeeze the air in the high-pressure box, and the air pressure inside the high-pressure box will increase. The valve will open when the spherical connection assembly approaches the spherical workpiece. The air in the high-pressure box will enter the diversion box through the pressure relief pipe. After being diverted by the diversion box, it will flow into multiple rubber bags through the booster pipe. Part of the high-pressure air entering the rubber bag will be sprayed onto the spherical workpiece through the capillary pores, which can remove the dust generated by turning attached to the surface of the spherical workpiece before the rubber bag comes into contact with the spherical workpiece.
[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0033] 1. In the present invention, a spherical workpiece is clamped by a plurality of elastic clamps, and a rubber bag is padded between the elastic clamps and the spherical workpiece to increase the friction between the elastic clamps and the spherical workpiece. The rotation speed of the plurality of spherical connection components is consistent with that of the spherical workpiece, that is, the spherical workpiece and the spherical connection components are in a relatively static state. When clamping the spherical workpiece, there is no need to stop the machine, and vibration and deflection will not occur when rotating at high speed or being pushed by turning equipment, thereby ensuring the processing accuracy of the spherical workpiece. At the same time, the spherical workpiece will not be thrown out due to rotation at the moment of cutting, thereby protecting the spherical workpiece and the internal facilities of the machine tool.
[0034] 2. In the present invention, the air in the high-pressure box enters the diversion box through the pressure relief pipe, and after being diverted by the diversion box, it flows into multiple rubber bags through the boost pipe. Part of the high-pressure air entering the rubber bags is sprayed onto the spherical workpiece through the capillary pores. Before the rubber bags come into contact with the spherical workpiece, dust generated by turning attached to the surface of the spherical workpiece can be removed, thereby preventing the rubber bags from scratching the surface of the spherical workpiece due to relative movement when squeezing the spherical workpiece, which is conducive to the high-stability production of high-precision spherical workpieces.
