The utility model relates to micromachining in the field of mechanical processing, and discloses a tool for repairing precision thin-walled step parts, a base, a positioning bolt and a grinding sleeve. The center of the base has a threaded through hole, and the positioning The bolt passes through the center hole of the thin-walled stepped part and is screwed to the threaded through hole. The grinding sleeve is a concave cylindrical structure, and the concave hole of the grinding sleeve is adapted to the step of the thin-walled stepped part. On the steps of the stepped parts, the front end of the grinding sleeve is pressed against the upper surface of the flange of the thin-walled stepped parts. The utility model effectively avoids the shortcomings of long manual blade repairing time, large errors, and uneven processing surface, reduces rework and scrapping, reduces production cost and labor intensity, greatly improves processing quality and efficiency, and is easy to implement.
Description
Technical field:
The utility model relates to a kind of instrument that grinds precise thin-wall step class part for repairing and especially repaiies the instrument that grinds micro-workpiece polishing wheel.
Background technology:
Grind precise thin-wall step class part repairing, during as step surfaces such as micro-workpiece polishing wheels, by the manual concrete steps of repairing while grinding of conventional blades be:
(1) pass Central of the parts hole by an elongate rod, part is suspended on accurate lock smith's clamp, rotary handle, makes vice jaw clamp gently part.
(2) vice and part are put under zoom stereomicroscope, under 80 times of multiplication factors, removed gently burr with blade, rotating part repeatedly, until jagged being removed.
(3) repair and be ground into, take off part.
In this process, blade very easily destroys the flatness of step surface, and processing time consuming effort, has higher requirements to operator's level of skill, and unstable product quality and production efficiency are low, are difficult to promote on a large scale.
Summary of the invention
The utility model, for existing methodical deficiency, provides a kind of and can significantly shorten traditional-handwork blade and repair the process time of grinding step surface for repairing the instrument that grinds precise thin-wall step class part, and can guarantee that working face point limit is without burr.
The technical solution adopted in the utility model is, a kind of for repairing the instrument that grinds precise thin-wall step class part, comprising: pedestal, bolt and grinding sleeve,
Described pedestal center has tapped through hole, described bolt is spirally connected through thin-walled step class Central of the parts hole and described tapped through hole, grinding sleeve is shrinkage pool cylindrical-shaped structure, the step adaptation of grinding sleeve shrinkage pool and thin-walled step class part, described grinding sleeve is enclosed within on the step of thin-walled step class part, and grinding sleeve front end is pressed in the lug upper surface of thin-walled step class part.
Compared with original processing method, use the utility model without repeatedly repairing with blade, without doing over again, only grinding sleeve need be buckled to the rotation of part step and can complete to repair several weeks and grind; And can Reusability, save material; Compared with original processing method, the utility model has avoided repairing the phenomenon that the time of grinding is long, error is large, finished surface is inhomogeneous effectively, and sharp limit is good and without burr, minimizing is done over again and scraps, reduce production cost and labour intensity, significantly promoted crudy and efficiency.
Accompanying drawing explanation

Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
In order better to implement the utility model, below in conjunction with Figure of description, the utility model is elaborated, refer to Figure of description 1,2,3.
For repairing an instrument that grinds precise thin-wall step class part, comprising: pedestal 1, bolt 3 and grinding sleeve 2,
Described pedestal center has tapped through hole 4, described bolt 3 is spirally connected through thin-walled step class Central of the parts hole and described tapped through hole 4, grinding sleeve 2 is shrinkage pool cylindrical-shaped structure, the step adaptation of grinding sleeve 2 shrinkage pools and thin-walled step class part, described grinding sleeve 2 is enclosed within on the step of thin-walled step class part, and grinding sleeve 2 front ends are pressed in the lug upper surface of thin-walled step class part.
For the ease of user's operation, grinding sleeve 2 ends are provided with handle.
In use procedure, determine hole size in grinding sleeve according to the diameter at part step place, grinding sleeve internal diameter is greater than the external diameter 0.01～0.02mm of step place.Grinding sleeve and submount material are all selected pure cast iron, and mating surface flatness is less than 0.002mm, are applicable to repairing grinding stepped diameters:
flange wall thickness: 0.01mm～0.5mm, repaiies and grinds the upper and lower plane parallelism requirement of front flange: 0.01mm～0.015mm.
Thin-walled step class part (such as polishing wheel) is fixed on base with bolt, grinding sleeve is shrinkage pool cylindrical-shaped structure, hole depth is greater than shoulder height, aperture is slightly larger than step place diameter, end face flatness is good, and grinding sleeve is put to polishing wheel, gently rotates several weeks with have gentle hands, can remove the burr of lug upper surface, complete to repair and grind.
Embodiment mono-
In the time of processing micro-workpiece polishing wheel, technological requirement flange keeps sharp limit and without burr, chamfering is less than 0.01mm, upper and lower plane parallelism reaches in 5um, but because thickness of flange only has 0.02mm, easily distortion, traditional milling tool cannot grind with repairing by clamping, uses this instrument to be easy to realize.
(1) polishing wheel is fixed on pedestal by bolt, clamps;
(2) grinding sleeve of the utility model instrument is placed on polishing wheel step, grinding sleeve machined surface contacts completely with lug upper surface;
(3) left hand is held up steady pedestal, and the right hand gently spin finishing overlaps a few;
(4) take off part, process finishing.
