Compared with the same products, the process equipment has the advantages of simple structure, low abrasion degree between the grinding wheel spindle and a shaft tile, high oil purity of the grinding wheel spindle, higher rigidity when the grinding wheel spindle rotates, smooth working, higher rotary working precision of the grinding wheel spindle, long service life, smooth feeding and reciprocation operation, high size precision, high conduction precision of a piece box, high efficiency for processing the outer surface of the bearing, easy use and easy operation; a guiding track under the grinding wheel frame has good shock resistance after being changed into a static pressure guiding track.
Description
Technical field:
The utility model relates to bearing products process equipment, particularly grinding machine.
Background technology:
The grinding machine that is used for bearing processing at present is a crankshaft grinding machine, and the grinding carriage grinding wheel spindle axial location that emery wheel is installed is a thrust bearing, and running accuracy is low, and grinding wheel spindle is thin and load is big, and service precision is low.Guide rail below the grinding carriage is the roller rolling guide, and vibratility is big, and vibration resistance is poor, and the low feeding dimensional accuracy of grinding carriage stiffness is low, and guide rail is short service life, does not satisfy the service precision of product.Workpiece box is by workpiece grinding wheel spindle conduction, operating difficulties, and the lengthwise movement of platen has manually also motor-driven finishing, and workbench can only crawl when motor-driven, can not move back and forth, and does not satisfy the processing needs of bearing products.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of cylindrical grinder is provided, and is simple in structure, precision height, operation easily, work operation balance and long service life.
The technical scheme that the utility model is adopted for achieving the above object is: cylindrical grinder, grinding wheel spindle is an annular sliding bearing, and grinding wheel spindle one end is contained on the grinding carriage, and the grinding wheel spindle transmission changes the off-load belt pulley into, the other end is equipped with belt pulley by bearing, and grinding carriage is two fuel tank gasoline pumps.
Guide rail below the described grinding carriage is a static pressure slot type hydrostatic slideway.
Described workpiece box connects reductor, and reductor is connected with the motor V-belt, and electromagnetism centreless clamp is housed on the workpiece box, and electromagnetism centreless clamp is in the centreless folder shell iron-core coil and floral disc to be housed.
Described workbench connects the reciprocating motion hydraulic means, and hydraulic means is that hydraulic valve, solenoid directional control valve and flow speed control valve are housed on the oil circuit between hydraulic cylinder and the workbench.
The electromagnetism regulation device is housed on the described console panel, the hydraulic pressure reversing arrangement, the workpiece variable-frequency stepless speed-regulating, emery wheel advance and retreat lubricating arrangement vertically back and forth has time-delay mechanism.
The utility model has outstanding feature compared with similar products, and it is simple in structure, and grinding wheel spindle changes two fuel tank gasoline pumps into, the overstriking of grinding wheel spindle diameter, watt lengthening thickening improves back off-load belt pulley and uses grinding wheel spindle not have load, lubricated cooling, olein filters, and grinding wheel spindle and bearing bush abrasion degree reduce greatly, and the purity of emery wheel axle box oil improves, when rotating, grinding wheel spindle can obtain higher rigidity, stable working makes grinding wheel spindle reach higher rotary work precision, long service life.Guide rail under the grinding carriage changes good anti-vibration behind the hydrostatic slideway into, and feeding back and forth operates steadily, the dimensional accuracy height, and workpiece box conduction precision height, machining bearing outer surface efficient height, easy to use, operation easily; Workbench guarantees vertically back and forth to operate steadily, stepless speed regulation, and time-delay mechanism can guarantee the linearity of bearing outside surface, makes the precision of converted products higher.Console panel improves and makes full use of old equipment body, has reduced cost, and guarantees high accuracy.
