Technical field
The present invention relates to a kind of single-spindle drilling machine.
Background technology
Digit Control Machine Tool is the main flow equipment of contemporary machinery manufacturing industry, the development experience of domestic numerical control lathe 30 years fall grand fluctuating, entered the maturity period by the growth stage.No matter be large-sized numerical control equipment or middle-size and small-size numerical control device, more and more to the functional requirement of lathe, also more and more higher to the performance requirement of lathe, particularly the special plane demand of some targeted processing characteristicies is also increasing.A kind of as wherein of numerical control drilling machine faces the requirement that these constantly promote too.Not only require numerical control drilling machine can realize feeding automation control, also require obtained higher concentricity the man-hour that adds of axle class disk-like accessory, easily realize gun drilling.
During traditional single shaft digital-controlled drilling machine processing work, workpiece is fixed, and generally carries out clamping by bench vice, flat-nose pliers, chuck or other special fixtures, and workpiece does not produce relative displacement with base after the anchor clamps clamping.When particularly axle class and disc type work being carried out Drilling operation, even with the higher scroll chuck of relative self-centering ratio of precision, the workpiece after the processing also is difficult to obtain good concentricity.Existing single shaft digital-controlled drilling machine Drilling operation has following deficiency:
1, the product concentricity behind the Drilling operation is poor.Workpiece can't obtain preferably, and concentricity mainly contains following three reasons: affected by the crudy of last process, there is tilt phenomenon in the workpiece cross section.Cause drilling to add man-hour, the firm contact of drill bit surface of the work produces inclination and offset, thereby makes the hole off-centre or the aperture that get out become large, can't guarantee product quality; 2. drilling adds the drilling cuttings that produces man-hour and does not clean out, and causes clamping workpiece integral inclination or off-centre.3. because of mechanical rigid deficiency or low precision, the product that causes processing can't be ensured the quality of products.
2, deep hole machining is very difficult, and drill bit skids easily or twists off.Mainly be that the bit cutting surface is blocked by drilling cuttings because can't in time discharge drilling cuttings during deep hole machining, cutting edge can't work, and simultaneously not smooth because of chip removal, the heat that causes adding man-hour sharply raises, thereby damages drill bit or drill chuck.
3, spindle motor need to be selected the larger motor of power ratio.When boring the workpiece of larger aperture, according to the Cutting Process principle, drilling adds need to select the lower speed of mainshaft man-hour, will obtain larger drilling torque than the slow-speed of revolution, certainly will select the spindle motor of relatively high power, so that hold the also corresponding increasing of main spindle box size of spindle motor.
Summary of the invention
The problems referred to above that exist in order to solve existing single-spindle drilling machine, the invention provides a kind of with the product good concentricity after workpiece slewing equipment, the processing, be easy to deep hole machining, spindle motor power is less, the main spindle box volume is less single-spindle drilling machine.
The present invention adopts following technical scheme:
