Body, operating efficiency are relatively low.
The content of the invention
For the utility model in view of the above-mentioned problems, providing a kind of grinder structure, this is simple and reasonable, in use will not be by
Enter bearing in chip caused by grinding and cause bearing failure, it is ensured that there is sufficiently long service life, while this practicality is new
Type product can process the semi arch of two concentric different-diameters simultaneously.
According to the technical solution of the utility model：A kind of grinder structure, including base, it is characterised in that：The base end
Face, which is installed, grinds frame, the reverse mounted grinding head motor of base top surface, installs multi-wedge belt pulley on the output shaft of grinding head motor, mill frame outer end is consolidated
Surely there is the support shaft being vertically arranged, bistrique is rotated by two bearings and is arranged in support shaft, by airtight between two bearings
Seal apparatus interval, bistrique surface upper end form polywedge bet installation portion, and the multi-wedge belt pulley is set with being tensioned on polywedge bet installation portion
Polywedge bet；Bistrique circumferential surface centre position is provided with emery wheel, and bistrique bottom face is equipped with gland, gland surfaces male cooperation
It is arranged in the groove of bistrique bottom surface.
As further improvement of the utility model, the gas sealing mechanism includes the axial air flue being arranged in support shaft
And radial direction air flue and the air guide collar that is arranged between two bearings, the air guide collar inwall integrally connected are formed radially
The sleeve pipe of extension is connected with radial direction air flue, and axial air flue is connected with radial direction air flue.
As further improvement of the utility model, the axial both ends of the air guide collar set a gas hood respectively, often
The inner edge of individual gas hood is pressed on the inner ring and outer ring of corresponding bearing respectively to outside.
Correspond to as further improvement of the utility model, on the bistrique at polywedge bet installation portion and band cover, band are set
Cover is fixed on mill frame.
It is of the present utility model to have technical effect that：The utility model product structure is simple, reasonable, passes through the installation in bistrique
Gas sealing mechanism is set on axle, and the gas sealing mechanism may insure at work, and emery wheel abrasive dust will not pollute bearing, it is ensured that bearing
Smooth movements, whole equipment have longer service life；In addition, being engaged in product using polywedge bet and multi-wedge belt pulley, grind
In bistrique rotation process is driven skidding will not occur for head motor；And the utility model product can be ground two simultaneously
Concentric but different diameter semicircular body, operating efficiency are higher.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is working state schematic representation of the present utility model.
Embodiment
Specific embodiment of the present utility model 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 utility model is a kind of grinder structure, including base 9, the end face of the base 9 installation mill frame
4, the top surface of base 9 reverse mounted grinding head motor 1 installs multi-wedge belt pulley 3 on the output shaft of grinding head motor 1, and mill frame 4 outer end is fixed with
The support shaft 10 being vertically arranged, bistrique 5 is rotated by two bearings and is arranged in support shaft 10, by airtight between two bearings
Seal apparatus 6 is spaced, the surface upper end of bistrique 5 formation polywedge bet installation portion 5-1, on the multi-wedge belt pulley 3 and polywedge bet installation portion 5-1
Tensioning sets polywedge bet 2；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, pressure
The rat of lid 11 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 utility model is as follows：The utility model product at work, can be ground two simultaneously with one heart
But the different workpiece 8 of diameter, grinding area are the arc surface of non-full circle, grinding is carried out by the way of similar to form grinding and is added
Work.Because when in use, base 9 is slidably mounted on working slider, when being ground workpiece, emery wheel 7 is with base 9 in working slider
It is upper reciprocating, 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 complete
Portion is ground.The inside of gas sealing mechanism 6 keeps malleation, can effectively prevent caused mill ash and steam in grinding process from entering axle
Inside is held, while will can also be taken away due to heat caused by high speed rotation, it is ensured that the service life of bearing.
