Description
Technical field
The utility model relates to lathe headstock, especially a kind of multiaxis hole processing special purpose transfer machine main spindle box.
Background technology
In the drilling processing of traditional porous part,, generally be the drilling processing in hole once to be finished simultaneously with building-block machine if the position accuracy demand between the hole is higher.The hole that the processing of existing multi-spindle drilling processes with building-block machine, its positional precision reach ± and 0.25mm is generally no problem, and manufacturing and designing also of building-block machine is easy to.But, the producer that has is in order to improve the quality of products, the position accuracy demand height in hole, and the centre-to-centre spacing between the hole is very little (for example to connect the blast pipe between silencer and the engine on the general gasoline engines, position accuracy demand between steam vent on it and two installing holes is just very high), once finish drilling processing simultaneously if still adopt building-block machine to carry out porous, the minimum distance between axles of the main shaft in each hole of inevitable requirement is less than 24mm (usually between 20～23mm), recommendation according to present building-block machine design manual, also can only reach 24mm even adopt the needle bearing main shaft that staggers to arrange its minimum distance between axles minimum, if adopt Hooks coupling universal coupling or template type structure, then the reliability of lathe is low.Thereby, be regarded as design " forbidden zone " usually in the industry less than the design of the main spindle box of 24mm distance between axles.When processing such porous part, generally be by mould at present, each hole is processed in drilling respectively, wastes time and energy very much, and production efficiency is low, and processes hole quality instability like this, is not suitable for the production of scale in enormous quantities.
The utility model content
Problem to be solved in the utility model provides a kind of minimum distance between axles of its main shaft of each machining hole that realizes less than 24mm, particularly the processing of the multiaxis hole between 20～23mm special purpose transfer machine main spindle box.
For addressing the above problem, multiaxis described in the utility model hole processing special purpose transfer machine main spindle box, comprise casing and be installed in case lid on the casing, lead and oil pump shaft are arranged on the casing, by bearing four main shafts and two intermediate propeller shafts are installed on the casing, they radially, cod is all staggered, first main shaft links by shaft coupling and power input shaft, described shaft coupling is made of intermeshing shaft coupling gear ring and joint shaft gear, joint shaft gear is fixed on first main shaft and meshes with first intermediate propeller shaft and second intermediate propeller shaft simultaneously, first intermediate propeller shaft and second main shaft and the 3rd main shaft pass through gears engaged, second intermediate propeller shaft and four main and oil pump shaft are by gears engaged, and the middle part of first main shaft is provided with the step shaft part of stepping down.
For implementation structure transmission in less space, reduce drive path in the utility model, first main shaft placed in the middle in four main shafts is not only made main shaft but also make power transmission shaft, and two intermediate propeller shafts are set, make the transmission scheme compactness back row.With axle radially, cod is staggered, can avoid each between centers radial dimension to interfere.By shaft coupling power is delivered on first main shaft and two intermediate propeller shafts simultaneously, it is little not only to take up room, and transmission is easy for installation, damping, has also improved the main shaft stressing conditions of serving as transmission.Under the limited situation of structure space, in order to improve the rigidity of main shaft, intermediate propeller shaft, structurally main shaft, intermediate propeller shaft are got as far as possible big external diameter, but, the stressed first less relatively main shaft of cutting middle part is got than the small stair diameter of axle in order to prevent that meshing gear and main shaft diameter from bumping.
The beneficial effects of the utility model are: can realize distance between axles less than 24mm, particularly processing is once finished in a plurality of holes of distance between axles between 20～23mm simultaneously, the hole site precision height that processes, and reliable in structure, working stability.
Description of drawings
Fig. 1 is the utility model cross sectional representation;
Fig. 2 is an expansion schematic diagram of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, drilling processing when the utility model is used to into three holes that isosceles triangle arranges, by casing 1, case lid 2, lead 12, oil pump shaft 13 and main shaft and intermediate propeller shaft constitute, case lid 2 places casing 1 side and top, oil pump shaft 13 is installed on the antetheca of casing 1, two leads 12 be supported on casing 1 before, on the back antetheca, by bearing four main shafts and two intermediate propeller shafts are installed on the casing 1, they radially, cod is all staggered, wherein first main shaft 6 links by shaft coupling and power input shaft, this shaft coupling is made up of intermeshing shaft coupling gear ring 7 and joint shaft gear 8, joint shaft gear 8 is fixed on first main shaft 6 by collar and meshes with first intermediate propeller shaft 9 and second intermediate propeller shaft 10 simultaneously, shaft coupling gear ring 7 is fixed on the power input shaft 14 by radial peg 3, first intermediate propeller shaft 9 and second main shaft 4 and the 3rd main shaft 5 pass through gears engaged, second intermediate propeller shaft 10 and four main 11 and oil pump shaft 13 are by gears engaged, and the middle part of first main shaft 6 is provided with the step shaft part 6a that steps down.See into from lathe the place ahead, transmission between second intermediate propeller shaft 10 and four main 11 and the oil pump shaft 13 is in I row, transmission between first intermediate propeller shaft 9 and second main shaft 4 and the 3rd main shaft 5 is in II row, and the transmission between first main shaft 6 and first intermediate propeller shaft 9 and second intermediate propeller shaft 10 is in III row.
As Fig. 2, the journal bearing of each main shaft is a ultralight series of balls bearing, for distance between axles is reduced, journal bearing all trends towards adopting needle bearing traditionally, in actual use, the service behaviour of needle bearing is stable inadequately, has therefore selected for use 1000902 ultralight series of balls bearings to replace needle bearing in the utility model, make its compact conformation, and stable work in work.The journal bearing of second main shaft 4 and the 3rd main shaft 5 is arranged in the centre of casing 1 front and back walls, interferes to avoid that radial dimension takes place between them.
