Abstract
The utility model discloses an efficient eccentric grinding wheel gear grinding device which comprises a grinding wheel main shaft with a main shaft barrel, a grinding wheel piece and a belt wheel. The grinding wheel piece is fixed at one end of the grinding wheel main shaft with the main shaft barrel through grinding wheel piece clamping plates at two sides of the device. The belt wheel is arranged at the other end of the grinding wheel main shaft with the main shaft barrel. An eccentric cushion cover is arranged between the grinding wheel main shaft with the main shaft barrel and the grinding wheel piece, a rotation curve of a grinding wheel is no longer a circle but an oval with tracks changing all the time, accordingly grinding points formed when the grinding wheel and saw teeth make a contact are no longer an unchanged concentric circular line, a sand hole blocking phenomenon is effectively avoided, the movement tracks of the oval with the tracks changing all the time enable the grinding points formed when the grinding wheel and the saw teeth make a contact to intermittently alternate, heating is not prone to occur and the phenomenon that the grinding wheel piece or the saw teeth are damaged due to heat is avoided.
Description
Technical field
The utility model relates to a kind of efficient centering type emery wheel roll flute device, relates to woodworking machinery corollary equipment field, is specially adapted to the saw blade of machine sawmilling prepared material is carried out the gear grinding machines of roll flute.
Background technology
Woodworking machinery saw blade gear grinding machine employing at present all is an aluminium matter down payment emery wheel sheet, and directly installs with one heart, and the characteristics of this type of saw blade are light weight, and sand hole is thin, is applicable to that the sawtooth alloy head to the woodworking machinery saw blade tempers.But often there is following problem in the actual mechanical process:
1, be concentric rotation because of emery wheel transmission main shaft and grinding wheel, when the woodworking machinery saw blade is carried out roll flute, the grinding points that emery wheel contacts with sawtooth also is the concentric circles line of fixing, because the concentric rotation of grinding wheel, the contact point of emery wheel and sawtooth also constitutes a fixing concentric turns because of the rotation of grinding wheel, and the grinding waste material that is produced in the roll flute process very easily is retained in the sand hole, blocks sand hole, cause the grinding wheel surface smoothing, greatly reduce the effect and the work efficiency of saw blade roll flute;
2, the grinding points that contacts with sawtooth of emery wheel is ground under the movement locus of concentric circles line repeatedly fast, is easy to cause grinding wheel and saw bade alloy hair heat, thereby causes burning out the phenomenon of grinding wheel or saw blade.
The utility model content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of efficient centering type emery wheel roll flute device.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: efficient centering type emery wheel roll flute device, the grinding wheel spindle, grinding wheel, the belt pulley that comprise band main shaft tube, described grinding wheel is fixed on an end of the grinding wheel spindle of band main shaft tube by the grinding wheel clamping plate of both sides, belt pulley is arranged on the other end of the grinding wheel spindle of band main shaft tube, it is characterized in that being provided with an eccentric cushion cover between the grinding wheel spindle of described band main shaft tube and the grinding wheel.
Compared with prior art, the utlity model has following outstanding advantage and effect: the utility model is provided with an eccentric cushion cover between the grinding wheel spindle of being with the main shaft tube and grinding wheel, the rotating curve that makes emery wheel then no longer is circular, but the ellipse that track changes at any time, the grinding points that emery wheel is contacted with sawtooth no longer is changeless concentric circles line, has effectively avoided the sand hole clogging; And the movement locus of the ellipse that track changes at any time, the grinding points that allows emery wheel contact with sawtooth has intermittent replacement, is difficult for heating, has avoided burning out the phenomenon of grinding wheel or saw blade.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As Fig. 1, shown in Figure 2, efficient centering type emery wheel roll flute device, the grinding wheel spindle 1 that comprises band main shaft tube, grinding wheel 2, belt pulley 3, described grinding wheel 2 is fixed on an end of the grinding wheel spindle 1 of band main shaft tube by the grinding wheel clamping plate 4 of both sides, belt pulley 3 is arranged on the other end of the grinding wheel spindle 1 of band main shaft tube, belt pulley connects motor by belt, work by the driven by motor grinding wheel, be provided with an eccentric cushion cover 5 between the grinding wheel spindle 1 of described band main shaft tube and the grinding wheel 2, the rotating curve that makes emery wheel then no longer is circular, but the ellipse that track changes at any time, the grinding points that emery wheel is contacted with sawtooth no longer is changeless concentric circles line, has effectively avoided the sand hole clogging; And the movement locus of the ellipse that track changes at any time, the grinding points that allows emery wheel contact with sawtooth has intermittent replacement, is difficult for heating, has avoided burning out the phenomenon of grinding wheel or saw blade.
It should be noted that at last: above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
