The mechanical manufacturing industry is the most basic industry of a country and also determines the overall level of the manufacturing industry of the country, and the development level of the mechanical manufacturing industry directly influences the improvement of the national economic level.
Turning, i.e., lathe machining, is a part of machining, and turning is mainly performed on a rotating workpiece with a turning tool. With the development of industry, people have higher and higher requirements on a lathe, and in order to perform corresponding processing on a workpiece to be processed on the lathe by using a drill bit, a reamer, a screw tap, a die, a knurling tool and the like, the probability of moving the workpiece to be processed in the process is reduced, the size error is reduced, and a tool turret is gradually derived. The tool turret greatly shortens the tool changing time in the production and machining process, and the number of the tools is greatly increased compared with the tools on the traditional lathe, so that the production efficiency of enterprises can be effectively improved.
The traditional tool turret (also called a tool rest) can only be provided with a turning tool or a boring tool to carry out the most basic turning processing on a workpiece to be processed, the tool turret has a single functional structure, the indexing accuracy of the tool turret is low, and the speed is slow, so that the requirements on the tool turret in practical application cannot be met.
In order to solve the problem of single function structure, the patent with the Chinese patent publication No. CN101633050A provides a power turret integrating turning and milling, which comprises a box body, wherein a motor is arranged in the box body, the motor comprises a motor electron and a motor rotor, the motor electron is fixedly arranged on the box body, a hollow spline shaft is fixedly connected in the middle of the motor rotor, one end of the hollow spline shaft is in transmission connection with a clutch, the clutch comprises a clutch movable rotating tooth and a clutch fixed rotating tooth, the clutch movable rotating tooth is connected with the hollow spline shaft, the clutch movable rotating tooth can move along the axial direction of the hollow spline shaft, the clutch fixed rotating tooth is in transmission connection with a first transmission shaft, the first transmission shaft penetrates through the hollow spline shaft, and the other end of the first transmission shaft is in transmission connection with a first spiral bevel gear; one end of the box body is relatively and rotatably connected with a cutter disc, a rotary cutter is installed on the cutter disc, one side of the rotary cutter is in transmission connection with a second transmission shaft, the other end of the second transmission shaft is in transmission connection with a second spiral bevel gear, and the second spiral bevel gear is meshed with the first spiral bevel gear. The single servo motor is utilized to realize two possibilities of controlling accurate transposition (also called tool changing) of the tool turret and controlling high-speed rotation of the rotary tool, the turning and milling processing functions are integrated, and the problems are reasonably solved.
However, the operation of the turret is controlled only by the servo motor, when the turret is used for processing a workpiece, the tool continuously cuts the workpiece to generate impact, so that the cutting force of the tool is periodically changed, the vibration of the workpiece is easily caused in the periodic continuous cutting process, and when the impact, the vibration or the resonance of the impact and the vibration are too large, the surface precision and the quality of the processed workpiece are reduced, and the processing efficiency is affected.
