At.
The beneficial effects of the utility model are: can prevent error caused by excessive polishing from increasing by the utility model,
The precision of inner hole polishing is greatly improved, has ensured the consistency of the inner hole precision of bulk article.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is status diagram when the utility model is mounted on cylindrical workpiece；
Fig. 2 is the perspective view structural schematic diagram of cylindrical workpiece in the utility model.
Specific embodiment
Referring to figs. 1 to 2, a kind of inner hole of the cylindrical workpiece with 8-shaped inner hole polishes structure, including with cylindrical workpiece 1
11 side inner ring of 8-shaped inner hole adaptation guide post 2,2 side of guide post is provided with a through slot, and the through slot is provided with fits therewith
The intermediate connection part of the polishing base item 21 matched, the width and 8-shaped inner hole 11 of the polishing base item 21 is wide, and lateral surface is set
It is set to the circular arc concave surface 22 for requiring internal diameter corresponding and concentric with 11 side of 8-shaped inner hole of its direction, the circular arc concave surface
22 are equipped at least two bolt holes 23, and the guide post 2 inside the through slot is equipped with threaded hole corresponding with bolt hole 23,
The polishing base item 21 is adapted to out of bolt hole 23 with threaded hole by hexagon socket head cap screw to be mounted in through slot；Polish base item
21 hardness is greater than cylindrical workpiece 1, and specifically, the cylindrical workpiece 1 is made of common carbon structural steel, the polishing base item
21 are made of stainless steel.1 liang of outside of the cylindrical workpiece is set as burnishing surface, in order to clamping position, before polishing, passes through workpiece
Positioning fixture carries out positioning clamping to cylindrical workpiece 1, and the auxiliary mould of the utility model is then installed to the 8 of cylindrical workpiece 1
In 11 side of font inner hole, polishing base item 21 polishes base item 21 and exposes guide post 2 towards the other side of 8-shaped inner hole 11
It is partially embedded into the intermediate connection part of 8-shaped inner hole 11, makes 11 1 side of 8-shaped inner hole of its circular arc concave surface 22 Yu its direction
Point a circular hole is formed, when polishing, rubbing head, which enters in the circular hole, polishes the side inner wall of 8-shaped inner hole 11, polishes
The material of head is less than stainless steel, the material greater than common carbon structural steel using hardness, when it is polished to the circle of polishing base item 21
When arc concave surface 22, that is, show that having reached polishing requires, and continues to rotate the 8-shaped inner hole that polishing also can not again to cylindrical workpiece 1
11 operation side plays a role, and withdrawing removes guide post 2 and 21 entirety of polishing base item at this time, reinstalls to one polished
Side makes its circular arc concave surface 22 and unpolished 11 1 side section of 8-shaped inner hole form a circular hole, continues the polishing of the other side；
It by the polishing structure of the utility model, can prevent error caused by excessive polishing from increasing, greatly improve inner hole polishing
Precision, ensured the consistency of the inner hole precision of bulk article.
Further, 22 both ends of circular arc concave surface are equipped at least two bolt holes 23, and the through slot both ends are corresponding
Guide post 2 on be also respectively equipped at least two threaded holes corresponding with bolt hole 23；The circular arc of 23 two sides of bolt hole
22 end of concave surface is additionally provided with the fastening counterbore 24 that internal diameter is less than bolt hole 23, is equipped in the through slot corresponding with fastening counterbore 24
Fastening thread hole, and be equipped with fastening bolt locked by fastening counterbore 24 with fastening thread hole.There is company by both ends
Binding structure, and the connection structure two sides at both ends are provided with and are fastenedly connected facility, polishing base item 21 can be firmly installed in
