The utility model content
Technical problem to be solved in the utility model is, provides a kind of and can make that processing cost is low, simple to operate, production efficiency is higher, can guarantee the Internal Spherical Surface process equipment of differential casing of the differential casing of high crudy and machining accuracy again.
For solving the problems of the technologies described above, the Internal Spherical Surface process equipment of a kind of differential casing that the utility model provides, it comprises lathe bed, be installed in the gearbox on the lathe bed, the headstock that is connected with gearbox, oil cylinder and the cutter frame mechanism that is fixed on the stretched into differential carrier intracoelomic cavity on the lathe bed are installed on the described headstock, described cutter frame mechanism is a linkage, comprise hinged sliding end and rotate end, described sliding end is connected with oil cylinder, on the free end of described rotation end cutter head is housed, described rotation end is to make the cutter head can be around the mechanism of 360 ° of rotations of the centre of sphere of differential carrier intracoelomic cavity.
After adopting above structure, compared with prior art, cutter frame mechanism the utlity model has following advantage: owing to can freely stretch in the differential casing, therefore, can be installed in cutter frame mechanism in advance on the headstock earlier, more whole cutter frame mechanism be stretched into differential casing and carry out sphere processing, need in cavity, not load and unload cutter like this, thereby save process time, cut down finished cost, the more important thing is the machining accuracy that can guarantee sphere, the quality that guarantees product.
As improvement, the sliding end of described cutter frame mechanism is connected with oil cylinder, is meant that cutter frame mechanism comprises slide bar, and described slide bar is connected with in-oil cylinder piston.After adopting this structure, make the slip of slide bar more steady, more can guarantee the machining accuracy of product.
As further improvement, described cutter frame mechanism also comprises connecting rod, knife rest support plate, knife bar, hinge pin, and described hinged sliding end and rotation end are meant slide bar and rod hinge connection; Described connecting rod and knife bar are hinged, and described knife bar is hinged by hinge pin and knife rest support plate; On the free end of described rotation end cutter head is housed, is meant that described cutter head is fixed on the free end of knife bar.After adopting the cutter frame mechanism of this linkage formula, cutter head can rotate the processing of carrying out Internal Spherical Surface around hinge pin, and can rotate to horizontal positioned to knife bar together with cutter head during feed, thereby, make structure simpler so smoothly by the through hole of differential casing.
The described differential casing that is slidingly connected on the lathe bed is meant that lathe bed is provided with slide rail, and described differential casing is fixed on the link, and described link and slide rail are slidingly matched.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of the Internal Spherical Surface process equipment of the utility model differential casing shown in the drawings as can be known, it comprises this equipment lathe bed 1, is installed in the gearbox 2 on the lathe bed 1, the headstock 4 that is connected with gearbox 2, and oil cylinder 3 and the cutter frame mechanism that is fixed on stretched into differential casing 6 inner chambers on the lathe bed 1 are installed on the described headstock 4.The described differential casing 6 that is slidingly connected on the lathe bed 1 is meant that lathe bed 1 is provided with slide rail 13, and described differential casing 6 is fixed on the link 12, and described link 12 is slidingly matched with slide rail 13.Described cutter frame mechanism is a linkage, comprise hinged sliding end and rotate end, described sliding end is connected with oil cylinder 3, and cutter head 8 is housed on the free end of described rotation end, and described rotation end is to make the cutter head 8 can be around the mechanism of 360 ° of rotations of the centre of sphere of differential carrier intracoelomic cavity.The sliding end of described cutter frame mechanism is connected with oil cylinder 3, is meant that cutter frame mechanism comprises slide bar 5, and the piston in described slide bar 5 and the oil cylinder 3 is connected.
Described cutter frame mechanism also comprises connecting rod 6, knife rest support plate 7, knife bar 9, hinge pin 10, and described hinged sliding end and rotation end are meant that slide bar 5 and connecting rod 6 are hinged; Described connecting rod 6 is hinged with knife bar 9, and described knife bar 9 is hinged by hinge pin 10 and knife rest support plate 7; Cutter head 8 is housed on the free end of described rotation end, is meant that described cutter head 8 is fixed on the free end of knife bar 9.
Before knife rest enters differential casing, can rotate to horizontal level to knife bar 9 around hinge pin 10 earlier, this moment, slide bar 5 and connecting rod 6 were horizontal level too.And then differential casing 11 moved toward headstock 4 directions by link 12 and being slidingly matched of slide rail 13, make whole cutter frame mechanism enter inner chamber by the through hole of differential casing 11 smoothly, the cutter head 8 that be fixed on knife bar 9 free ends this moment also is positioned in the inner chamber.Then, oil cylinder 3 comes into operation, and drives slide bar 5 and moves toward the directions away from differential casing 11, and this moment, drivening rod 6 moved, and makes knife bar 9 around hinge pin 10 rotations, so cutter head 8 also rotatablely moves as the plane around hinge pin 10.Simultaneously headstock 4 rotates around axis under the drive of equipment motor, so also drives whole cutter frame mechanism and cutter head 8 winding apparatus main shafts rotate.Therefore, can utilize the dual rotary of cutter head 8 to move and reach the processing of differential casing Internal Spherical Surface.
