Description
Technical field
This utility model relates to levitation device, the levitation device of a kind of grinding wheel spindle.
Background technology
Belt pulley is one of most important part in V belt translation structure, is widely used in the various gearings of the industries such as automobile, lathe, household electrical appliances.At present, domestic most of belt pulley manufacturing enterprise is used mostly traditional brazed shank tool for the processing of its critical process V type wedge groove.
For belt pulley grooving cutter, monodentate cutter can be divided into according to the number of teeth, bidentate cutter, three serrated knife tools, during grooving cutter uses, the cutter tooth part of cutter is easy to wear, thus not and cutting precision is the highest to cause the cutting dynamics of cutter, it is thus desirable to replacing cutter, and cutter is relatively costly, it is thus desirable to cutter is repaired, cutter is repaired and generally uses wheel grinding reparation, but for multitooth tool, need clamping is repeated several times, clamping all has clamping error each time, after multiple clamping, cause Cutting tool installation manner error big, so that the reparation precision of cutter reduces, the serious cutter that will directly result in is scrapped, thus cause production cost higher, and repair the cutter that precision is the highest, the machining accuracy that will also result in belt pulley is the highest, have a strong impact on the quality of product.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of simple in construction, noise be little and the levitation device of the grinding wheel spindle of good anti-vibration.
The purpose of this utility model is achieved through the following technical solutions: the levitation device of a kind of grinding wheel spindle, it includes support, main shaft, emery wheel, drive motor and oil cylinder, described emery wheel is arranged on the outfan of main shaft by locking nut, motor is driven to be connected with the input of main shaft, the two ends of described main shaft are mounted on suspension bearing, fuel feed hole and oil outlet is offered on suspension bearing, between two suspension bearings, bearing mounting base is installed, oil-feed tank is left between described support and bearing mounting base, oil-feed tank connects with fuel feed hole and oil outlet respectively, the oil filler point connected with oil-feed tank and spill port is offered on described support, oil fuel tube it is sealedly connected with on oil filler point, oil return pipe it is sealedly connected with on spill port, oil return pipe is all connected with oil cylinder with oil fuel tube.
Described fuel feed hole and oil outlet are multiple, and are evenly distributed on same circumference.
Described fuel feed hole is symmetrical relative to the axial line of suspension bearing with oil outlet.
This utility model has the advantage that grinding wheel spindle levitation device of the present utility model, it is provided with suspension bearing, thus ensure that the axiality that emery wheel rotates, thus ensure that the grinding accuracy of cutter, and use suspension bearing, noise is little, rotating speed is high, good anti-vibration when rotating to make main shaft, and makes service life of main shaft long.

In figure, 1-locking nut, 2-suspension bearing, 3-fuel feed hole, 4-oil-feed tank, 5-bearing mounting base, 6-oil filler point, 7-oil fuel tube, 8-drives motor, 9-oil cylinder, 10-emery wheel, 11-oil outlet, 12-main shaft, 13-spill port, 14-oil return pipe, 15-support.
Detailed description of the invention
Being further described this utility model below in conjunction with the accompanying drawings, protection domain of the present utility model is not limited to the following stated:
nullAs shown in Figure 1，A kind of levitation device of grinding wheel spindle，It includes support 15、Main shaft 12、Emery wheel 10、Drive motor 8 and oil cylinder 9，Described emery wheel 10 is arranged on the outfan of main shaft 12 by locking nut 1，Motor 8 is driven to be connected with the input of main shaft 12，The two ends of described main shaft 12 are mounted on suspension bearing 2，Fuel feed hole 3 and oil outlet 11 is offered on suspension bearing 2，Bearing mounting base 5 is installed between two suspension bearings 2，Oil-feed tank 4 is left between described support 15 and bearing mounting base 5，Oil-feed tank 4 connects with fuel feed hole 3 and oil outlet 11 respectively，The oil filler point 6 connected with oil-feed tank 4 and spill port 13 is offered on described support 15，Oil fuel tube 7 it is sealedly connected with on oil filler point 6，Oil return pipe 14 it is sealedly connected with on spill port 13，Oil return pipe 14 is all connected with oil cylinder 9 with oil fuel tube 7，By oil cylinder 9 to suspension bearing 2 fuel feeding，So that the two ends of main shaft float in pressure oil all the time，Can ensure that during work and between main shaft and bearing, be in neat liquid Frotteurism，Thus reduce the abrasion of main shaft，Improve the service life of main shaft，And its frictional resistance is little，So that the running accuracy of main shaft is high、The feature that bearing capacity is strong，And adaptability and vibration resistance to rotating speed are the best，So that the emery wheel 10 being connected with main shaft runs the most steady，Thus improve the reparation precision of cutter，And main shaft its noise in rotation process is little，The harm of workshop noise can be reduced.
In the present embodiment, described fuel feed hole 3 and oil outlet 11 are multiple, and be evenly distributed on same circumference, further, described fuel feed hole 3 is symmetrical relative to the axial line of suspension bearing 2 with oil outlet 11, when main shaft run up generation be displaced to a direction time, its corresponding oil pocket dynamic pressure pressure reaches maximum, at this moment its gap is minimum, during its opposite direction oil pocket pressure minimum on the contrary, gap is maximum, at this moment fuel feed hole 3 and oil outlet 11 reduce pressure when just playing gap maximum, main shaft is made to return to bearing centre position, so that main shaft is maintained at the center of bearing in making, reach optimal duty, thus ensure that emery wheel 10 all rotates in a circumference, thus improve the correction precision of cutter.
