Abstract
The utility model provides a guide rail grinding head spindle, which comprises the spindle, a shell, a bearing, a grinding wheel device, a motor stator and a motor rotor, and is characterized in that the spindle is arranged in the shell through the bearing; the grinding wheel device is arranged on a front end of the spindle; a motor is arranged on a rear end of the spindle, and comprises a motor shell, the motor rotor and the motor stator; the shell is fixedly connected with the motor shell; an oil inlet is arranged on an upper end of the shell; oil pump ports are arranged on two sides of the shell. The guide rail grinding head 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 guide rail grinding spindle.
Background technology
Grinder emery wheel grinding-head is the vitals in grinder, and the reasonability of grinding spindle structural design is one of principal element directly affecting its function; Existing grinding spindle structure rotating accuracy is low, supporting rigidity is poor, a little less than bearing capacity, cannot realize high-speed grinding (being that grinding speed is greater than 35m/s-50m/s).Grinding wheel head structure adopts sliding bearing mostly; rotating accuracy is low, main shaft temperature rise under the situation of High Rotation Speed is higher, grinding speed is in 35m/s; main shaft, under the situation of low speed rotation, can not form dynamic pressure between bearing shell and axle journal oil film wedge, therefore processes charging roller variety range little; During due to grinding wheel head structure grinding, can not adopt high-rate cutting technique, so the technical standards such as the dimensional accuracy of charging roller, surface roughness play pendulum in process of production.
Utility model content
The utility model object is for the existing above-mentioned technical problem of prior art, and a kind of guide rail grinding spindle is provided.
Realize above-mentioned purpose, the utility model proposes a kind of guide rail grinding spindle is provided, comprise main shaft, housing, bearing and grinding wheel unit, it is characterized in that: described main shaft is arranged in housing by bearing, described front-end of spindle is provided with grinding wheel unit, and described rear-end of spindle is provided with motor, described motor comprises electric machine casing, rotor and motor stator, described housing is fixedly connected with electric machine casing, and described housing upper end is provided with oil-in, and described housing both sides are provided with oil pumping mouthful.
As preferably, described grinding wheel unit is provided with protective cover.
As preferably, described housing bottom is provided with installing rack.
As preferably, described bearing is dynamic/static piezoelectric bearing.
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 guide rail grinding spindle described in the utility model.
The specific embodiment
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
As shown in Figure 1, a kind of guide rail grinding spindle, comprise main shaft 1, housing 2, bearing 3 and grinding wheel unit 4, it is characterized in that: described main shaft 1 is arranged in housing 2 by bearing 3, described main shaft 1 front end is provided with grinding wheel unit 4, described main shaft 1 rear end is provided with motor 5, described motor 5 comprises electric machine casing 51, rotor 52 and motor stator 53, described housing 2 is fixedly connected with electric machine casing 51, described housing 2 upper ends are provided with oil-in 6, described housing 2 both sides are provided with oil pumping mouth 7, described grinding wheel unit 4 is provided with protective cover 8, described housing 2 bottoms are provided with installing rack 9, described bearing 3 is dynamic/static piezoelectric bearing.
Operation principle of the present utility model is: utilize the grinding wheel unit 4 axial compression power and the revolving force that are ground part and this device to realize ground effect, can select one-sided rotation and two kinds of duties of bidirectional rotation according to the needs of production status.
Specific embodiment described herein is only to the explanation for example of the utility model structure.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
