Abstract
The utility model relates to a grinding wheel, which is suitable for being used as a grinding wheel which can reversely grinding the end surface of an inner hole in mechanical process. The utility model is characterized in that the right end of a grinding wheel 1 is provided with an inclined flute, the depth of the flute is t, and the included angle of the flute and the end surface A is beta. The utility model has the advantage of processing more than three step holes and reversal grinding end surfaces without secondary clamping, so the process quality can be assured, and the production rate is high.
Description
The utility model relates to a kind of emery wheel, is specially adapted to have in the machining hole end surface emery wheel in the reverse grinding.
The emery wheel of general grinding step hole, its end face is accomplished the spill (see figure 2), and certain wedge angle is arranged, and does not have the less endoporus of undercut or empty cutter and by face grinding, part as shown in Figure 1 with grinding.
When having three above step holes to need grinding in the endoporus of part to be processed, and the opposite two ends of left and right directions are need be by mill the time, part for example shown in Figure 3.Because of it has strict axiality and perpendicularity requirement, processing technology need be carried out secondary (turning around) clamping routinely, and its machining accuracy has a strong impact on the crudy and the productivity ratio of part because of twice clamping is difficult to guarantee.
The purpose of this utility model, just be to overcome prior art exists because of twice clamping cause of low quality, the shortcoming that productivity ratio is low, and then provide a kind of and do not need twice clamping and can realize the emery wheel of reverse grinding.
The purpose of this utility model is achieved in that
A kind of emery wheel is specially adapted to have in the machining hole end surface emery wheel in the reverse grinding.It is characterized in that it is t that right-hand member at emery wheel 1 is provided with the degree of depth, and with the angle of end face A be the groove of the band gradient of β.
The purpose of this utility model can also further be realized by following technical measures:
Aforesaid emery wheel, angle β=30 °-60 °
Aforesaid emery wheel, the K portion of groove is a wedge angle, or the straight angle of band 1-2mm.
Aforesaid emery wheel, the degree of depth t=2-3mm of groove.
The utility model has the advantages that: solved the technical barrier that present technology has three above step holes and has reverse grinding to require in can not the endoporus to machined part, and emery wheel making is easy, part processing quality secure (clamping need not turn around to carry out twice), the efficient height.
Below in conjunction with Figure of description and embodiment the utility model is further described:
Fig. 1 is the part to be processed figure with a step hole.
Fig. 2 is a grinding endoporus grinding wheel structure schematic diagram commonly used in the prior art.
Fig. 3 is for having the part to be processed figure of a plurality of (three) step hole.
Fig. 4 is grinding wheel structure figure of the present utility model.
Embodiment:
Fig. 4 is embodiment of the present utility model:
It is t that the right-hand member of its medium plain emery wheel 1 is provided with a degree of depth, and with the angle of end face A be the groove of β=45 °: the K portion of groove is a wedge angle, but reach the technological requirement of processing grinding wheel as required, K portion also can be made into the band 1-2mm straight angle (being that end face A is the wide anchor ring of band 1-2mm on the circumference), groove depth t=2mm.
2 for installing the mandrel of emery wheel among the figure, and 3 is trip bolt.
Emery wheel 1 is loaded on the mandrel 2 during use, and it is fastening with screw 3, starting the lathe bistrique and the headstock then also rotates part, bistrique tends to the processing parts endoporus d4 of part (see figure 3) elder generation and oppositely depends on face grinding B with the right side A of emery wheel 1 then by face grinding A1 reprocessing endoporus d3, d2 under feed motion drives.
Claims (4)
1, a kind of emery wheel is specially adapted to have in the machining hole end surface emery wheel in the reverse grinding, it is characterized in that right-hand member at emery wheel (1) be provided with the degree of depth be t and with the angle of end face A be the groove of the band gradient of β.
2, emery wheel according to claim 1 is characterized in that angle β=30 °-60 °.
3, emery wheel according to claim 1, the K portion that it is characterized in that groove is a wedge angle, or the straight angle of band 1-2mm.
4, emery wheel according to claim 1 is characterized in that the degree of depth t=2-3mm of groove.
