Description
Technical field
The present invention relates to a kind of internal thread grinding machine grinding carriage dip angle adjusting mechanism.
Background technology
Internal thread grinding machine adopts the method for plunge grinding to carry out machining screw usually, by adjusting the angle of grinding wheel spindle axis and workpiece centre of gyration line, meets the internal thread grinding demand of different lead angle.In screw thread process, the lead angle of dissimilar workpiece is scarcely same, then required grinding carriage inclination angle and the angle of main shaft of grinding carriage axis and workpiece centre of gyration line are also not quite similar, so the inclination angle of grinding carriage often needs frequent adjustment, and the speed of grinding carriage Inclination maneuver and whether accurate working (machining) efficiency and the crudy directly affecting workpiece.Existing common internal thread grinding machine, mostly the adjustment of grinding carriage is the adjustment being realized grinding carriage angle by worm and gear or ball-screw-transmission, but all Shortcomings.The feature of Worm Wheel System self, not only rotate not steady when adjusting lead angle, control accuracy is little, and transmission efficiency is low; Ball-screw-transmission is the rectilinear motion rotation of screw rod being converted into nut, so the rotation that the rotation of screw rod will be converted into grinding wheel spindle box is a difficult point, the structure that hinged one end, usual employing screw rod one end is unsettled, obviously, in this structure when bolt rotary, screw rod can depart from home position, therefore rotate not steady when adjusting lead angle, cause control accuracy low, and it is large to take up room, cause structural redundancy, it is actual that this class formation can not meet current production.Grinding machine processing is usually used as last procedure in work pieces process, and its required precision is very important.The angle of conventional threads grinding machine is all visually observed by angle scale high scale, and this localization method is comparatively coarse, and adjustment result varies with each individual, and error is comparatively large, and along with the increase of adjustment number of times, error can be increasing.
Summary of the invention
The object of the invention is the problem solving traditional internal thread grinding machine grinding carriage Inclination maneuver, provide a kind of internal thread grinding machine grinding carriage dip angle adjusting mechanism, realize emery wheel angle and accurately adjust efficiently.
For achieving the above object, the present invention adopts following technical scheme:
A kind of internal thread grinding machine grinding carriage dip angle adjusting mechanism, comprises moving guide rail, grinding carriage base, arc-shaped rail, T-shaped bolt, grinding wheel spindle box, magnetic railings ruler, reading head, nut seat, ball-screw, Multifunction digital indicating meter, described grinding carriage base is bolted on moving guide rail, described arc-shaped rail is arranged on grinding carriage base, described grinding wheel spindle box is arranged on grinding carriage base by T-shaped bolt, grinding wheel spindle box can move along arc-shaped rail relative to grinding carriage base, the rear end face of grinding wheel spindle box is smooth arc surface, and the center of circle of circular arc and grinding wheel center superposition, described magnetic railings ruler is arranged on this smooth arc surface, corresponding reading head is installed on grinding carriage base, and reading head contacts with magnetic railings ruler, Multifunction digital indicating meter is connected with reading head by cable, when grinding wheel spindle box rotates, the inclination angle of reading head and magnetic railings ruler real time record grinding carriage base, and shown by Multifunction digital indicating meter, described ball-screw is arranged on grinding carriage base and grinding wheel spindle box back seat.
Described ball-screw comprises screw rod and nut, for screw pair connects between nut and screw rod; Described screw rod is arranged on grinding carriage base by thrust ball bearing, described grinding wheel spindle box installed surface there is a slide block slot, nut seat is arranged in slide block slot, be connected with grinding wheel spindle box by moving sets, described nut is connected by revolute pair with between nut seat, the rotation of screw rod is converted into the rotation of grinding wheel spindle box by nut seat, thus realizes the adjustment at grinding carriage inclination angle.
Compared with prior art, the invention has the beneficial effects as follows:
Utilize the centering ability of arc-shaped rail, simplify the structure of grinding carriage base and grinding wheel spindle box, make machine tool structure compacter; By magnetic railings ruler and reading head Real-Time Monitoring emery wheel inclination angle, improve Adjustment precision, save regulation time; When screw turns, nut moves around leading screw in the vertical direction, nut seat is driven also to want in the vertical direction to move, again because nut seat can only slide in the slide block slot on grinding wheel spindle box back seat, constraint and power effect under, grinding wheel spindle box will rotate along arc-shaped rail, thus realizes the adjustment at emery wheel inclination angle, has that control realization is simple, stability of rotation, rotating accuracy are high, a feature of compact conformation and good manufacturability.
