The precision grinding head is strong in machining capability, convenient to assemble and disassemble, and suitable for efficiently grinding workpieces which are demanding in boring precision and surface roughness.
Description
Technical field
The utility model relates to a kind of bistrique, particularly a kind of high speed and precision internal grinding head.
Background technology
Domestic widely used internal grinding head mainly adopts the sleeve two ends to arrange the structure of a pair of rolling bearing respectively at present.Because the two end supports main shaft, main shaft is when Speed Grinding, and main shaft can produce distortion, produces vibrations simultaneously, causes rotating accuracy low, poor rigidity, thereby the inaccessible very high request of bore area crudy.
The utility model content
The purpose of this utility model provides the high internal grinding head of a kind of machining accuracy, overcomes existing internal grinding head shortcoming, and production efficiency and bore area crudy are significantly improved.
The utility model provides a kind of accurate bistrique, comprises ring flange, main shaft, sleeve, stop collar, spacer and belt pulley; Described ring flange is connected with main shaft by nut; Described main shaft is connected by many strong points of multiple bearing structure with sleeve; Respectively there are two pairs of cylinder roller bearings at described sleeve two ends; A pair of deep groove ball bearing is installed in the middle of the described sleeve; Described sleeve two ends are equipped with seal cover; Described belt pulley is connected by nut with main shaft; Cylinder roller bearing outer ring, described sleeve two ends and sleeve are matched in clearance.
Further, cylinder roller bearing outer ring, described sleeve two ends is spacing by sleeve step and seal cover shoulder face.
Further, separate by spacer between described sleeve two ends cylinder roller bearing and the deep groove ball bearing.
Further, described sleeve two ends cylinder roller bearing inner ring and main shaft are interference fit.
Further, a pair of deep groove ball bearing outer ring and the sleeve of installing in the middle of the described sleeve is interference fits.
Further, described a pair of deep groove ball bearing inner ring and main shaft are interference fits.
Further, described a pair of deep groove ball bearing is separated by stop collar.
Further, between described seal cover and the main shaft sealing ring is installed.
Further, the O RunddichtringO is installed between described seal cover and the sleeve.
The utility model and existing internal grinding head relatively, its rigidity height, the rotating accuracy height, shake little, stable working, suitable high precision inner-pore grinding, alternative import internal grinding head.
