Abstract
The utility model relates to a grinding head adjusting mechanism. A shaft motor drives a main shaft to rotate. A grinding wheel is arranged on the main shaft. The main shaft is arranged in a main shaft casing, and a bearing is arranged between the main shaft and the main shaft casing. An axial cord of the main shaft is parallel to an axial cord of the main shaft casing to have an eccentricity h. The main shaft casing can be arranged on a machine body in a relative rotating mode. A fine tuning motor drives the main shaft casing to rotate by a synchronized belt. The utility model solves the problem that the existing grinding head adjusting mechanism can not exactly and stably adjust the grinding head, so the adjustment precision of the grinding head of the main shaft is influenced, the precision duration of the grinding machine is decreased, etc. The utility model has the characteristic that the grinding head can be exactly and stably adjusted, so the adjustment precision of the grinding head of the main shaft is improved, the precision duration of the grinding machine is prolonged effectively, etc.
Description
Technical field
The utility model relates to a kind of bistrique governor motion.
Technical background
A kind of bistrique elevating mechanism (patent No.: 98233632.2) of special-shaped edge polisher, comprise body, the bistrique slip cap, elevating endless screw, eccentric bushing, wherein on slip cap, be processed with helical rack, the helical rack engagement on elevating endless screw and the bistrique slip cap, elevating endless screw then is fixed on the body by eccentric bushing.
Technique scheme adopts screw rod and tooth bar etc. that the adjusting of grade form is arranged for regulating the bistrique height, because screw rod and tooth bar etc. all have pitch or tooth pitch, therefore just can't realize the adjustment of bistrique exactly, thereby influence the adjustment precision of main shaft bistrique, reduce the duration of grinding machine precision.
Summary of the invention
The utility model has solved the adjustment that existing bistrique governor motion can't be realized the bistrique exactly, thereby influence the adjustment precision of main shaft bistrique, the problems such as duration of grinding machine precision have been reduced, a kind of adjustment that can realize the bistrique exactly is provided, thereby improve the adjustment precision of main shaft bistrique, effectively prolonged the bistrique governor motion of the duration of grinding machine precision.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the spindle motor drive shaft is rotated, main shaft is provided with emery wheel, main shaft is located in the main shaft housing, is provided with bearing between the two, and the axis of main shaft is parallel with the axis of main shaft housing and have offset h; The main shaft housing is located on the body rotatably, and the fine setting motor is by the rotation of the main shaft of band drive synchronously housing.The fine setting motor changes main shaft bistrique high and low position, and keeps the main shaft depth of parallelism constant by the rotation of the main shaft of band drive synchronously housing, makes the adjustment exactly, thereby improves main shaft bistrique adjustment precision, effectively prolongs the machine tool accuracy duration.
As preferably, described fine setting motor output end is provided with reducing gear, and this reducing gear drives band synchronously.Wherein, reducing gear can reduce the output speed of fine setting motor, drives the speed that the main shaft housing rotates to reduce synchronous band, thereby improves the adjustment precision of main shaft bistrique.
As preferably, described main shaft housing is sheathed on the body, and the main shaft housing is provided with end cover near the emery wheel end, and this end cap is provided with the eccentric through-hole that passes for main shaft.Wherein, end cover can be realized the sealing between body and main shaft housing on the one hand, can realize the sealing between main shaft housing and main shaft on the other hand, prevents that dust and abrasive dust from entering, and guarantees the normal operation of grinding machine.
Therefore, the utlity model has the adjustment that can realize the bistrique exactly, thereby improve the adjustment precision of main shaft bistrique, effectively prolonged the characteristics such as duration of grinding machine precision.The fine setting motor changes main shaft bistrique high and low position, and keeps the main shaft depth of parallelism constant by the rotation of the main shaft of band drive synchronously housing, makes the adjustment exactly, thereby improves main shaft bistrique adjustment precision, effectively prolongs the machine tool accuracy duration.Wherein, reducing gear can reduce the output speed of fine setting motor, drives the speed that the main shaft housing rotates to reduce synchronous band, thereby improves the adjustment precision of main shaft bistrique.Wherein, end cover can be realized the sealing between body and main shaft housing on the one hand, can realize the sealing between main shaft housing and main shaft on the other hand, prevents that dust and abrasive dust from entering, and guarantees the normal operation of grinding machine.
