Abstract
The utility model provides a turning lathe wheelhead spindle, which comprises the spindle, a shell, a bearing and a grinding wheel device, wherein the spindle is arranged in the shell through the bearing; the grinding wheel device is arranged on a front end of the spindle; a high rigid fixing support structure is arranged on the front end of the spindle; a motor is arranged on a rear end of the spindle, and comprises a revolving shaft, a motor stator and a motor rotor; the revolving shaft and the spindle of the motor are of an integral structure. The turning lathe wheelhead spindle has the beneficial effects that the grinding wheel device can be rotated bi-directionally, the rotation accuracy is high, the linear velocity of a grinding wheel is improved, the grinding capacity is improved, and a foundation is laid for applying heavy cut process on a grinding machine; meanwhile, stepless speed change can be realized on the spindle, and the processing range is enlarged; the processing quality accuracy is improved stably, and the production efficiency is improved.
Description
Technical field
The utility model relates to grinding spindle, especially relates to a kind of lathe grinding spindle.
Background technology
The grinding of workpiece is carried out conventionally on grinding machine, and grinding machine is divided into internal grinder, cylindrical grinder, flat stone mill, end face mill and some other special grinding machine, and staff can choose applicable grinding machine according to the different parts of grinding on workpiece.Aspect bar or tube outer diameter grinding and glossing, conventionally adopt cylindrical grinder corase grind to cut the technique that finishing polish matches with buffing wheel at present.Although cylindrical grinder grinding grinding speed is fast, the surface roughness reaching is very low, and for polishing size, is not easy to control before finishing polish technique.Emery wheel finishing polish technique polishing effect is relatively good, but also has the problem that stock removal is low.In daily production, operating personnel always coordinate and repeatedly work between these two techniques, waste time and energy, and production efficiency is low.Above processing method is also subject to device-restrictive, and the length of work piece is also restricted.
Utility model content
The utility model object is for the existing above-mentioned technical problem of prior art, and a kind of lathe grinding spindle is provided.
Realize above-mentioned purpose, the utility model proposes a kind of lathe grinding spindle is provided, comprise main shaft, housing, bearing, grinding wheel unit, described main shaft is arranged in housing by bearing, described front-end of spindle is provided with grinding wheel unit, and described front-end of spindle is provided with height and rigidly fixes supporting construction, and described rear-end of spindle is provided with motor, described motor comprises rotating shaft, motor stator and rotor, and rotating shaft and the main shaft of described motor are structure as a whole.
As preferably, described housing bottom is provided with lathe mounting bracket.
As preferably, described bearing is dynamic/static piezoelectric bearing.
As preferably, described front casing, motor housing and bonnet, described housing comprises that front casing, motor housing and bonnet are fixedly connected with by screw.
As preferably, described motor adopts high-accuracy frequency control motor.
Compared with prior art, the utility model beneficial effect is: grinding wheel unit can Double-directional rotary, and rotating accuracy is high, has heightened grinding speed, has improved grinding capacity, for implement high-rate cutting technique on grinder, lays the foundation; On this main shaft, can realize infinitely variable speeds, even rolling bearing clearance, still in perfect condition, has expanded the range of work under extremely slow-revving situation simultaneously; The bearing capacity of main axle structure is significantly improved than original structure, and therefore main shaft all energy even runnings under the situation of High Rotation Speed, without the phenomenon of any noise, vibration; Due to the enhancing of this main axle structure function, grinding has in process of production adopted high-rate cutting technique, not only makes crudy stable accuracy promote but also has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of lathe grinding spindle described in the utility model.
