The equipment is characterized by the inclusion of a clamping fixture, adjusting screws, shafts, an adjusting screw rod, compressing shafts, positioning pin shafts and a compressed spring, wherein a tail handle is arranged at one end of the clamping fixture, the other end of the clamping fixture is formed into a cylindrical shape, threaded holes for the mounting of the adjusting screws are formed at the upper parts of the two ends of the clamping fixture, unthreaded holes for the mounting of the compressing shafts and an unthreaded hole for the mounting of the compressed spring are formed at one end of the clamping fixture, two unthreaded holes for the mounting of the positioning pin shafts are formed at the lower part of the clamping fixture, two unthreaded holes for the mounting of the shafts are formed at the upper part of the clamping fixture, a threaded hole for the mounting of the adjusting screw rod is formed at the upper part of the clamping fixture, and the lower end of the adjusting screw rod is formed into a cone; and the two positioning pin shafts are mounted in the two unthreaded holes at the lower part of the clamping fixture, and the two shafts, the three compressing shafts, the adjusting screw rod, the compressed spring and the two adjusting screws are mounted sequentially on the clamping fixture. The utility model has the advantages that the processing precision of the bush inner holes is improved, the repairing and processing time is shortened, and the time and the labor are saved.
Description
Technical field: the invention is to be used for the equipment that high-precision grinder main shaft bearing shell is repaired processing.
Background technology: cylindrical grinder such as model is 3151,3161,316M, all be the very high lathes of some machining accuracies, their main shaft bearing shell all is two semicircles, and bearing shell is the critical piece of these lathes, bearing shell is repaired level and crudy, directly influences the machining accuracy of lathe.
During repairing, machine repairing benchwork generally all is to make a dummy shaft, the size that makes dummy shaft than main shaft actual size approximately less than 0.02mm, tint and grinding bearing shell on dummy shaft at inner surface of bearing bush, scrape the grinding point with triangular scraper then, have 4 bearing shells on each lathe, machine repairing benchwork will be finished 4 bearing shells and regard with special esteem and cut general 2～3 days time of needs, promptly wasting man-hour requires great effort again, and be subjected to the restriction of everyone own level, be difficult to again guarantee the scraping quality, directly influence the crudy of grinding machine.
Content when sending out: the purpose of the invention provides a kind of quality that guarantees to repair bearing shell, time saving and energy saving high accuracy two halves bearing shell endoporus process equipment: the purpose of the invention is to realize by following technical scheme: high accuracy two halves bearing shell endoporus process equipment, it is characterized in that by mold, adjust screw, axle, adjust screw rod, compression axis, alignment pin and stage clip constitute, mold one end is shaped on caudal peduncle, the other end is made tubular, make installation on top, mold two ends and adjust the screw thread hole, at one end make unthreaded hole that compression axis is installed and the unthreaded hole that stage clip is installed, make two of the unthreaded holes that alignment pin is installed in the mold bottom, make two of the unthreaded holes of installation shaft on mold top, make installation on mold top and adjust the screw flight hole, adjust the screw rod lower end and make cone, flat is made in the lower end of axle; Two alignment pin are installed in two unthreaded holes of mold bottom, successively two axles, three compression axises, adjustment screw rod, stage clip and two adjustment screws are contained on the mold.
The advantage of the invention: owing to adopted mold, and top bearing shell, lower bearing be contained in the mold endoporus, through adjusting screw rod, axle and alignment pin positioning and fixing, utilize internal grinder to process the endoporus of bearing shell, improved the machining accuracy of bearing shell endoporus, shortened repairing process time again, time saving and energy saving.

The specific embodiment: high accuracy two halves bearing shell endoporus process equipment, it is characterized in that by mold, adjust screw, axle, adjust screw rod, compression axis, alignment pin and stage clip constitute, mold one end is shaped on caudal peduncle, the other end is made tubular, make installation on top, mold two ends and adjust the screw thread hole, at one end make unthreaded hole that compression axis is installed and the unthreaded hole that stage clip is installed, make two of the unthreaded holes that alignment pin is installed in the mold bottom, make two of the unthreaded holes of installation shaft on mold top, make installation on mold top and adjust the screw flight hole, adjust the screw rod lower end and make cone, flat is made in the lower end of axle; Two alignment pin are installed in two unthreaded holes of mold bottom, successively two axles, three compression axises, adjustment screw rod, stage clip and two adjustment screws are contained on the mold.
The diameter of bore size of mold is to determine by the main spindle box body opening of mapping grinding machine.
Operation instruction:
Top bearing shell, lower bearing are contained in the endoporus of mold, alignment pin separates top bearing shell, lower bearing lower end, begin to tighten the adjustment screw rod, compression axis one end contacts with cone on adjusting screw rod, under the effect of cone, promote compression axis, compression axis one end contacts with the flat that make the lower end of axle, the compression axis impeller-hub rotates, axle is fastening with top bearing shell, lower bearing upper end, top bearing shell, lower bearing are just fixedly secured in the endoporus of mold, can process the endoporus of top bearing shell, lower bearing on internal grinder.
