The function of the driving center belongs to a clamping positioning tool of a high-precision processing system, and a clamping mode for processing high-precision parts is formed by center positioning and end face driving.
The traditional driving center is dynamic, and the risk of influencing the machining precision exists; in addition, when the traditional driving center is used for machining, a plurality of driving centers are required to be replaced due to different diameters and sizes of workpieces, positioning correction is also required, the process is complicated, time is wasted, and production efficiency is affected. The designed multifunctional driving center can solve the problems by only adjusting the driving shaft.
Disclosure of Invention
The utility model aims to overcome the defects of the technology and provide a novel driving center which is fixed and can be suitable for multiple middle diameter sizes.
The utility model provides a novel drive is top, includes integrative drive dabber, driving disk and top, the driving disk is between drive dabber and top, the cover is equipped with the drive locating sleeve on the top, drive locating sleeve keeps away from driving disk one end and is equipped with the gland, the top is pointed and is passed drive locating sleeve and gland, be equipped with a plurality of drive shafts that pass the gland on the drive locating sleeve, a plurality of the drive shaft is to use top axis as the centre of a circle, presents a plurality of annular and arranges, the drive shaft equipartition on every annular is arranged.
Further, the driving positioning sleeve is provided with a thick through hole and a thin through hole which are communicated, the thick through hole is close to one end of the driving disc, the thin through hole is close to one end of the gland, the driving shaft is arranged in the thin through hole, the driving shaft is connected with a spring in the thick through hole, one end of the spring is connected to the driving shaft, and the other end of the spring is abutted to the driving disc.
Further, the driving disc is connected with the driving positioning sleeve and the gland is connected with the driving positioning sleeve by adopting inner hexagon screws.
The utility model has the advantages that: the movable center is reasonable in structure, and the center and the driving mandrel are in an integral structure, so that the problem that the movable center has machining precision risks is avoided; the multi-ring driving shafts are uniformly distributed, so that one driving center is suitable for workpieces with various diameters, and the production efficiency is improved.
