The utility model relates to the technical field of machine tools, in particular to a four-station power turret tool rest of a numerical control lathe.
Background art:
CNC turret tool rest is a necessary machine tool accessory for machining center and CNC lathe, especially for full-function CNC lathe. At present, CNC machine tools are developing rapidly. On the one hand, they are developing towards high speed, high efficiency and high precision. At the same time, there are also many problems in manufacturing industry, such as CNC transformation of original equipment and system upgrade. As a key accessory, the high-performance CNC turret tool rest is of great significance for improving the reliability, stability and efficiency of the whole machine tool operation. CNC turret tool rest realizes automatic tool change and rotary power tool transmission through rotary indexing, which has high technical content and tends to professional development and production. Therefore, the research, development and application of CNC turret tool rest have attracted the attention of CNC machine tool industry. The existing turret tool rest has low positioning accuracy, low transmission efficiency and great noise, vibration and impact during transmission.
In order to solve the shortage in the current market, it is urgent to improve the technology of turret tool rest device, so that it can better process workpieces and promote the development of machine tool industry.
Technical realization elements:
The utility model aims to provide a four-station power turret tool rest of a numerical control lathe, so as to solve the problems of low positioning accuracy, low transmission efficiency and large noise, vibration and impact during transmission of the existing turret tool rest in the above background technology.
In order to achieve the above purpose, the utility model provides the following technical scheme: a four-station power turret tool rest of a numerical control lathe comprises a spindle box, a cutter head, a servo motor and a spindle, wherein a dust cover is fixed at the upper end of the spindle box through bolts, a driving motor is installed at the front of the spindle box, a positioning hydraulic cylinder is installed at the lower end of the spindle box, the spindle is installed in the spindle box through bearings, a first steering worm wheel is installed in the middle of the spindle box, and a cutter head is installed at the front end of the spindle box. The first steer worm gear is meshed with a second steer worm gear installed on a driving shaft, that driving shaft is installed on the headstock through a bearing, and the front end of the drive shaft is connected with a driving motor; The second steering worm gear and the first steering worm gear are installed in the oil tank; The auxiliary gear is installed on the main shaft behind the cutter head through a bearing, and the auxiliary gear is meshed with the transmission gear slidably installed on the cutter head; A cutter is installed at the front end of a rotatable rotating shaft on the cutter head, and a transmission gear is fixed at the rear end of the rotating shaft; A transition shaft rod is installed on the spindle box at the upper end of the spindle through a bearing; A first transition gear is installed on the transition shaft; The first transition gear is meshed with the driving gear; The servo motor is fixed on the spindle box through a bracket; A dust cover is installed on the spindle box outside the servo motor; A driving gear is installed on the output shaft at the front end of the servo motor.
Preferably, the upper end of the spindle box is provided with a sealed upper cover, which is detachable on the spindle box, and the dust cover installed on the sealed upper cover is detachable at the same time.
Preferably, both the driving motor and the servo motor are HD70 adjustable servo motors, and the positioning hydraulic cylinder is PL-GSX servo cylinder.
Preferably, four groups of rotating shafts are uniformly installed on the cutter head, the rotating shafts can be fixed inside the cutter head, and the transmission gear is fixed at the rear end of the rotating shaft; At the same time, there are eight groups of positioning holes on the cutter head on the rotating shaft side, and the positions of the positioning holes correspond to the positioning shaft rods on the positioning hydraulic cylinder.
Preferably, the second transition gear is installed at the front end of the transition shaft, and the second transition gear is meshed with the auxiliary gear, while the second transition gear is not in contact with the transmission gear.
Preferably, the joint between the drive shaft and the headstock is provided with a gasket, and the joint between the spindle and the headstock is sealed, and the lubricating oil level filled in the oil tank is located below the drive shaft and contacts with the second steering worm wheel.
Compared with the prior art, the utility model has the advantages that the four-station power turret tool rest of the numerical control lathe is provided with a servo motor matched with the steering worm, and the steering worm is arranged in the oil tank, thus prolonging the service life; A pair of high-precision involute cylindrical steering worms has high transmission efficiency, is suitable for short-distance transmission, reduces vibration and impact between gear transmissions and reduces noise generation; At the same time, the tool is driven by the servo motor next to it. Machining workpiece, using positioning hydraulic cylinder and positioning hole to fix cutter head, can realize accurate positioning, which can better process workpiece and promote the development of machine tool industry.
