In the grinding process of bearing ring, its required precision is very high, and the centering of machine tool compresses the precision needs of the grinding that can not meet bearing, thus numerical control bearing grinding machine in, generally all adopt the grinding method of electromagnetic type centerless fixture structure.
Electric magnetic no-core clamp by clamping fixture seat, solenoid, magnetic pole and be not in the mood for supporting form.Solenoid is equipped with in rotating shaft outside at workpiece spindle front end, on the end face of workpiece spindle front end, magnetic pole is installed, in grinding process, solenoid energising, the magnetic force producing on magnetic pole, makes workpiece under the effect of workpiece spindle and supporting absorption of workpieces, around the centre of gyration rotation of self.
Under the effect of supporting, the centre of gyration of the centre of gyration of workpiece skew workpiece spindle, two centres of gyration have certain distance, i.e. and offset, because offset and eccentric direction guarantee that outer surface of workpiece is reliably positioned not to be in the mood on bearing-surface.
Summary of the invention
The object of the invention is that supporting arrangement positioning support precision was low in the past in order to solve, supporting rigidity is low, adjust problem often, provide the outer presetting circular arc of a kind of bearing grinder machine not to be in the mood for supporting arrangement, the present invention is fixedly installed by the angle of the gathering sill of left circular arc supporting guide pad and right circular arc supporting guide pad, adopt the outer preset mechanism of machine to adjust location outward at machine simultaneously, positioning precision is high, owing to having changed, support rotary design in the past, thereby increased supporting rigidity, lighter supporting cut, wearing and tearing have been alleviated, thereby reduced adjustment number of times, and adopt to be that machine is outer presettingly can improve grinding accuracy, improved greatly grinding efficiency.
The present invention is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
The outer presetting circular arc of a kind of bearing grinder machine is not in the mood for supporting arrangement, comprise base, also be provided with the L-type plate and the outer preset mechanism of machine that are fixed on base, the outer preset mechanism of described machine positions and is fixedly mounted on L-type plate by the locating pin on L-type plate, the outer preset mechanism of described machine comprises bearing plate, left circular arc supporting and the supporting of right circular arc, on bearing plate, be installed with left circular arc supporting guide pad and right circular arc supporting guide pad, on described left circular arc supporting guide pad and right circular arc supporting guide pad, all offer along bearing to be processed gathering sill radially, left circular arc supporting and the supporting of right circular arc are slidably arranged in respectively in the gathering sill of left circular arc supporting guide pad and right circular arc supporting guide pad, to adapt to processing parts the eccentric adjustment amount of different-diameter, and by securing member, fix to limit the supporting of left circular arc and right circular arc and be bearing in gathering sill and be free to slide.
Described locating pin is provided with three, and wherein two are arranged on one end that L-type plate is connected with base, and another is arranged on the other end of L-type plate.
Described left circular arc supporting and the supporting of right circular arc are arc-shaped surface with workpiece to be processed contact-making surface.
The gathering sill of described left circular arc supporting guide pad and right circular arc supporting guide pad is 0-90 ° of angle.
The invention has the beneficial effects as follows: the present invention is fixedly installed by the angle of the gathering sill of left circular arc supporting guide pad and right circular arc supporting guide pad, adopt the outer preset mechanism of machine to adjust location outward at machine simultaneously, positioning precision is high, owing to having changed, support rotary design in the past, thereby increased supporting rigidity, lighter supporting cut, wearing and tearing have been alleviated, thereby reduced adjustment number of times, and adopt to be that machine is outer presettingly can improve grinding accuracy, improved greatly grinding efficiency.
