Description

Technical Field

[0001] The utility model relates to the technical field of boring and polishing heads, in particular to an adjustable boring and polishing head. Background Art

[0002] Existing rolling polishing tools mostly use gears to adjust their size. Two sets of external gears are installed on the mandrel, and two sets of internal gears are installed in the inner hole of the outer sleeve. The internal gears mesh with the external gears for adjustment. The coaxiality of the internal and external gears is extremely poor, and the adjustment is not flexible, which can easily lead to the scrapping of the two sets of gears and the mandrel, making the entire tool unusable. In addition, the processing of internal and external gears is difficult and costly; in addition, the existing rolling polishing tools cannot bore the excess before polishing, which invisibly increases the difficulty of the previous processing steps, has low processing efficiency, and cannot guarantee the high-precision processing requirements of the workpiece.

[0003] The boring diameter of the existing boring and polishing head is fixed, which is inconvenient to process borings of different coarseness and fineness, affecting the working range of the device. In view of the above situation, technical innovation is carried out on the basis of the existing boring and polishing head. For this purpose, we propose an adjustable boring and polishing head.
