Description
Technical field
The utility model relates to a kind of jig, relates in particular to a kind of cylinder sleeve boring machine self-centering fixture.
Background technology
My company, semifinishing equipment thick for cylinder sleeve bore is double-shaft cylinder sleeve boring machine at present, its excircle orientation benchmark is the positioning sleeve endoporus matching with the large cylindrical in cylinder sleeve end, there is following shortcoming in this locate mode: Dui Qian road processing request is high: slightly cutting with scissors operation is with cylinder sleeve big end surface and large excircle orientation, before institute, road cuts off operation cylinder sleeve long head and car location cylindrical together, positioning reference plane while forming bore hole, make like this to cut off operation processing beat long, cause preceding working procedure to become bottleneck operation; Bad surplus of hair causes greatly waste: being the more endoporus of casting flaw owing to cutting off operation workpiece processing location, so rough turn location cylindrical and endoporus axiality is out poor, for ensuring the quality of products, is generally increasing blank cylindrical surplus; Positioning precision is low: fixture centring ring and cylinder sleeve are matched in clearance, the fit clearance of centring ring and workpiece requires at 0.06-0.10mm, because location cylindrical is roughing, workpiece surface roughness and dimensional tolerance stability are bad, make the interior hole dimension of actual location circle bigger than normal; Change kind cost high: when production line is changed product, must change centring ring and foundation ring, and after the cylinder sleeve of processing some, centring ring surface abrasion, also needs to change, these have increased product thread-changing cost.
Utility model content
The utility model provides a kind of and has solved wastage of material, the requirement of Dui Qian road is high, positioning precision is high, change the cylinder sleeve boring machine self-centering fixture of the technical problem that kind cost is high.
The technical scheme that the utility model addresses the above problem is:
A kind of cylinder sleeve boring machine self-centering fixture, comprise base plate, slide block one, slide block two, cushion block, centring ring, line rail one, line rail two, tooth bar one, two and two rotating shafts of tooth bar, described line rail one and line rail two parallel interval are arranged on described base plate, install respectively on online rail one and line rail two at the two ends of described slide block one, and the end of slide block one is provided with tooth bar one, install respectively on online rail one and line rail two at the two ends of described slide block two, and the end of slide block two is provided with tooth bar two, described slide block one is parallel to each other with slide block two, described cushion block is arranged on respectively the inner side of slide block one and slide block two, described centring ring is arranged on base plate between described cushion block, described rotating shaft is arranged on a side of base plate, and in rotating shaft, be separately installed with pitch wheel one and gear two, described gear one is intermeshing with tooth bar one, described gear two is intermeshing with tooth bar two.
On the basis of technique scheme, the utility model can also do following improvement,
Further, have positioning datum hole on described base plate, described positioning datum hole is coaxial with centring ring;
Further, described tooth bar one is relative with tooth bar two positions;
Further, it also comprises oil cylinder, and described oil cylinder arranges the outside of slide block one;
Further, described slide block one and slide block two are wedge shape.
The beneficial effects of the utility model are:
1, process capability promotes: preceding working procedure cylinder sleeve, without processing location cylindrical, cuts off operation and only cuts long head, and process capability promotes;
2, can reduce cylindrical place, location blank allowance: because of blank cylindrical rule relatively, without casting iron knurl defect, can, directly as locating surface, with former processing technology ratio, have surplus to reduce space.
3, cylinder sleeve positioning precision improves: in the time just installing, and axiality, the perpendicularity of proofreading and correct Self-centering device and main shaft with standard gauge, after cylinder sleeve processing, endoporus linearity is less than 0.01mm, Wall-Thickness Difference 0.04mm, cylinder sleeve bore precision meets the requirement of thick hinge operation far away.
4, thread-changing loss is few: when production line changes kind, and when the cylinder sleeve of all external diameters in ￠ 160～￠ 90 scopes, the replacing frock of need not taking time, frock loss while having reduced thread-changing, production capacity loss.
5, the utility model is to utilize the ingenious transmission of dislocation of two groups of gears and rack and pinion and gear to realize self-centering.
