When using lathe in machining, except control system can provide the control corresponding instruction, the very important point be numerically controlled lathe need be equipped be easy to control, the cutter tower of tool changing rapidly and accurately, so that with the required various cutters of clamping, finish flexibly, the processing of various geometries easily, vertical solution push type broach tower is the essential functional part of Digit Control Machine Tool, directly influence the Performance And Reliability of Digit Control Machine Tool, it is the fault point occurred frequently of lathe, it is fast that vertical solution push type broach tower should have a transposition, characteristics such as positioning accuracy height.In the prior art, the drive unit of the axially-movable of vertical solution push type broach tower cutter axis is a hydraulic cylinder, and the drive unit that cutter axis rotatablely moves is a hydraulic motor.Vertical solution push type broach tower is to use fluid motor-driven because rotatablely move when allowing the used new swivel of next procedure of processing to the operating position at cutter axis, the speed of fluid motor-driven is not very fast, the used new cutter of next procedure of processing is forwarded to the operating position neither be very accurate, it is longer to produce time, labor productivity is not very high
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, it is fast to propose a kind of transposition, the vertical hydraulic servo turret that positioning accuracy is high.
The present invention is achieved using the following method.
Vertical hydraulic servo turret has housing, circular cylindrical cavity is arranged in the housing, the cavity mouth of housing front end has axis and the cavity axis annular stiff end fluted disc on same straight line, the annular hydraulic cylinder is arranged between stiff end fluted disc and the cavity, axis and the cutter axis of cavity axis on same straight line are arranged in the cavity, the front end of cutter axis stretches out before the stiff end fluted disc, the front end of cutter axis is connected with cutterhead, cutterhead is connected with the annular movable end fluted disc with the engagement of stiff end fluted disc, the cavity mouth of the rear end of cutter axis behind the cavity stretches out, the rear end of cutter axis is connected with the cutter axis spur gear, on cutter axis a section in cavity the annular piston that matches with annular hydraulic cylinder is arranged, the axis worm-wheel shaft parallel with the axis of cutter axis arranged on the housing, the worm-wheel shaft spur gear that worm gear is arranged on the worm-wheel shaft and mesh with the cutter axis spur gear, the worm screw that is meshed with worm gear on the worm-wheel shaft is arranged on the housing, the servomotor that links to each other with transmission device with worm screw is arranged on the housing.
The present invention adopts electric liquid in conjunction with driving, when numerically controlled lathe in use needs tool changing, travel forward vertically with the annular piston on the annular hydraulic cylinder promotion cutter axis of vertical solution push type broach tower earlier, driving cutter axis and cutterhead travels forward vertically, make movable end fluted disc on the cutterhead break away from engagement with the stiff end fluted disc, then with the rotation of driven by servomotor cutter axis, allow the used new cutter of next procedure of processing forward the operating position exactly to, the annular piston that promotes on the cutter axis with annular hydraulic cylinder moves vertically backward again, allow movable end fluted disc and stiff end fluted disc on the cutterhead recover engagement, compress end-toothed disc, cutterhead is located accurately and realize tool changing.
The present invention is with the rotation of driven by servomotor cutter axis, the speed of driven by servomotor is fast, it is very accurate that the used new cutter of next procedure of processing is forwarded to the operating position, because transposition is fast, the positioning accuracy height can be raised labour productivity effectively, shortens and produces time, particularly when processing geometry than complicated parts, the ability to work of processing technology adaptability and continous-stable obviously improves; Speed with the rotation of driven by servomotor cutter axis is very fast, servo motor shaft and cutter axis need bigger rotating ratio, the present invention has worm gear, worm gearing between servo motor shaft and cutter axis, when bigger gearratio, the deflecting force that can bear is bigger, can the bigger workpiece of workhardness.
Below in conjunction with accompanying drawing, the present invention is further described.
