Description
Technical Field
The utility model belongs to the technical field related to machining tools, and particularly relates to an adjusting tool for efficiently finishing the tooth surfaces of bevel gears and worms.
Background
When the traditional centrifugal barreling and polishing processing equipment is used for processing disk parts such as gears, the axis of the disk parts such as the gears is parallel to the axis of the charging barrel after the disk parts are installed, abrasive flow rotates along with the charging barrel during polishing processing, a streamline formed by flowing of the abrasive flow rotates around the axis of the charging barrel, the processed parts rotate in the opposite direction, and the abrasive flow enters the tooth grooves to perform polishing processing on the surfaces of the gear teeth through the relative motion of the abrasive flow and the processed parts. For the worm shaft and the bevel gear with the small taper angle, the tooth direction of the worm shaft and the bevel gear with the small taper angle gradually shrinks from the large end to the small end, and the tooth width gradually decreases, so that the abrasive flow rotates around the axis of the cylinder to form the finish machining on the top surface of the tooth on one hand, and simultaneously, the abrasive flow flows in the tooth groove to further generate a certain finish machining effect on the tooth surface due to the flow guiding effect of the tooth groove.
The prior centrifugal type barreling and polishing equipment is mainly used for polishing the surfaces of disk parts by forming abrasive material flow under the driving of a charging barrel and then generating micro-cutting action on the surfaces of the processed parts by relative motion between the abrasive material flow and the surfaces of the processed parts, thereby realizing the processing of the surfaces; fig. 1 is a schematic diagram of gear machining movement of a conventional barreling and burnishing machine, in which solid lines with arrows indicate the rotation directions of bevel gears or worms and dotted arrows indicate the flow directions of abrasive streams. However, when the relative movement direction between the abrasive and the surface to be processed is perpendicular or even the structure of the surface to be processed causes the relative movement speed between the abrasive and the surface to be processed to decrease, the processing effect will be significantly decreased, and the conventional method is to increase the processing time to achieve the processing target. However, for parts such as gears, after the machining time is increased, when the target surface machining effect meets the requirement, the rest positions may be over-machined, so as to damage the tooth profile curve or other key parameters of the gear, and further influence the meshing state or transmission precision of the worm or bevel gear in the transmission.
