The whole service life of individual wheel grinding device.The semicircle that existing product is difficult to be ground two simultaneously with one heart but diameter is different
Body, operating efficiency are relatively low.
The content of the invention
For the present invention in view of the above-mentioned problems, providing a kind of grinder structure, this is simple and reasonable, in use will not be due to mill
Chip enters bearing and causes bearing failure caused by cutting, it is ensured that has sufficiently long service life, while product of the present invention can
To process the semi arch of two concentric different-diameters simultaneously.
According to technical scheme：A kind of grinder structure, including base, it is characterised in that：The base end face peace
Dress mill frame, base top surface reverse mounted grinding head motor install multi-wedge belt pulley on the output shaft of grinding head motor, and mill frame outer end is fixed with
The support shaft being vertically arranged, bistrique are rotated by two bearings and are arranged in support shaft, pass through level Hermetic Package between two bearings
Interval is put, bistrique surface upper end forms polywedge bet installation portion, and the multi-wedge belt pulley sets more wedges with tensioning on polywedge bet installation portion
Band；Bistrique circumferential surface centre position is provided with emery wheel, and bistrique bottom face is equipped with gland, and gland surfaces male cooperation is set
In the groove of bistrique bottom surface.
As a further improvement on the present invention, the gas sealing mechanism includes axial air flue and the footpath being arranged in support shaft
To air flue and the air guide collar being arranged between two bearings, what the air guide collar inwall integrally connected was formed radially extends
Sleeve pipe be connected with radial direction air flue, axial air flue is connected with radial direction air flue.
As a further improvement on the present invention, the axial both ends of the air guide collar set a gas hood, Mei Geqi respectively
The inner edge of cover is pressed on the inner ring and outer ring of corresponding bearing respectively to outside.
As a further improvement on the present invention, correspond on the bistrique at polywedge bet installation portion and band cover is set, band cover is solid
Due on mill frame.
The technical effects of the invention are that：Product structure of the present invention is simple, reasonable, by being set in the installation axle of bistrique
Gas sealing mechanism, the gas sealing mechanism may insure that at work emery wheel abrasive dust will not pollute bearing, it is ensured that bearing operation is suitable
Freely, whole equipment has longer service life；In addition, it is engaged in product using polywedge bet and multi-wedge belt pulley, grinding head motor
Skidding will not occur in bistrique rotation process is driven；And product of the present invention can be ground two simultaneously with one heart but diameter
Different semicircular bodies, operating efficiency are higher.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the working state schematic representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including grinding head motor 1, polywedge bet 2, multi-wedge belt pulley 3, mill frame 4, bistrique 5, polywedge bet installation portion 5-1,
Gas sealing mechanism 6, axial air flue 6-1 and radial direction air flue 6-2, air guide collar 6-3, gas hood 6-4, emery wheel 7, workpiece 8, base 9, branch
Support axle 10, gland 11, band cover 12 etc..
As shown in Figure 1, 2, the present invention is a kind of grinder structure, including base 9, the end face of the base 9 installation mill frame 4, bottom
The seat reverse mounted grinding head motor 1 of 9 top surfaces, multi-wedge belt pulley 3 is installed on the output shaft of grinding head motor 1, and mill frame 4 outer end is fixed with vertically
The support shaft 10 of setting, bistrique 5 are rotated by two bearings and are arranged in support shaft 10, pass through level Hermetic Package between two bearings
6 intervals are put, the surface upper end of bistrique 5 forms polywedge bet installation portion 5-1, and the multi-wedge belt pulley 3 on polywedge bet installation portion 5-1 with being tensioned
Polywedge bet 2 is set；The circumferential surface centre position of bistrique 5 is provided with emery wheel 7, and the bottom face of bistrique 5 is equipped with gland 11, gland 11
Rat is equipped with the groove of the bottom surface of bistrique 5.
Gas sealing mechanism 6 includes axial the air flue 6-1 and radial direction air flue 6-2 that are arranged in support shaft 10 and is arranged at two
Air guide collar 6-3 between bearing, the sleeve pipe radially extended that the air guide collar 6-3 inwalls integrally connected is formed and radial direction
Air flue 6-2 is connected, and axial air flue 6-1 is connected with radial direction air flue 6-2.
Air guide collar 6-3 axial both ends set gas hood a 6-4, each gas hood 6-4 inner edge and outside to distinguish respectively
It is pressed on the inner ring and outer ring of corresponding bearing.
Correspond on bistrique 5 at polywedge bet installation portion 5-1 and band cover 12 is set, band cover 12 is fixed on mill frame 4.
The course of work of the present invention is as follows：Product of the present invention at work, can be ground simultaneously two with one heart but diameter not
Same workpiece 8, grinding area are the arc surface of non-full circle, and grinding is carried out by the way of similar to form grinding.Due to
When in use, base 9 is slidably mounted on working slider, and when being ground workpiece, emery wheel 7 is made past with base 9 on working slider
Multiple motion, an angle then is being rotated, grinding operation is carried out to workpiece 8, so circulation is until the arc surface of workpiece 8 is all ground
Go out.The inside of gas sealing mechanism 6 keeps malleation, can effectively prevent caused mill ash and steam in grinding process from entering in bearing
Portion, while will can also be taken away due to heat caused by high speed rotation, it is ensured that the service life of bearing.
