High strength sharpening machine bistrique
Technical field
The utility model relates to a kind of sharpening machine, especially relates to a kind of high strength sharpening machine bistrique, belongs to steel-making auxiliary equipment technical field.
Background technology
The sharpening machine specialty is used for the oxide skin and the defective on the circular forging rolling material of grinding surface, reaches the required surface quality requirement of client.Present sharpening machine bistrique; Its spindle pulley directly is set in grinding spindle one end and is fixedly connected with main shaft, is rotated thereby motor drives main shaft through the belt drives spindle pulley, and this moment, spindle nose should carry the moment of torsion that belt pulley transmits; Carry the radially expanding force of belt again; Therefore the spindle precision is low, and the running balance is relatively poor, and service life is shorter.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and the high strength sharpening machine bistrique that a kind of transmission accuracy is high, run stability is good and service life is long is provided.
The purpose of the utility model is achieved in that a kind of high strength sharpening machine bistrique; It comprises grinding head box body and grinding spindle, and said grinding spindle is installed in the grinding head box body, and stretch out outside the grinding head box body at the two ends of grinding spindle; Said grinding spindle one end is installed with the emery wheel cover; Said emery wheel cover outer rim is set with emery wheel, and be characterized in: said grinding head box body rear end is set with the off-load flange shaft, and said off-load flange shaft is hollow structure; Off-load flange shaft outer rim is equipped with spindle pulley; Said spindle pulley front end is set with belt wheel forward flange dish, and the spindle pulley rear end is provided with the belt wheel rear stub, and said belt wheel rear stub is fixedly connected with the grinding spindle other end.
Compared with prior art, the beneficial effect of the utility model is:
A kind of high strength sharpening machine of the utility model bistrique; Its grinding head box body rear end is set with the unloading flange shaft, and spindle pulley is installed on the unloading flange shaft, therefore when sharpening machine is worked; Spindle nose only carries the moment of torsion that belt pulley transmits; And the radially expanding force of belt is delivered on the main shaft casing through the unloading flange shaft, so its transmission accuracy is high, run stability is good, and service life is longer.
