Description
Technical field
The utility model belongs to lathe inner chamber sphere device, particularly a kind of device that utilizes engine lathe car inner chamber sphere.
Background technology
Differential mechanism as automobile has a shell; Differential gear is housed in it; The hole of shell both sides is fitted with semiaxis; In the past owing to the Internal Spherical Surface of processing differential mechanism with machine tool is very difficult; Therefore a kind of pipelining of special production differential mechanism appears on the market; But the cost of this streamline is very expensive; So still adopt the molding cutter of centre numerically controlled lathe to process usually at present; Earlier molding cutter is placed the differential carrier intracoelomic cavity; Pass through digital control system again by servomotor; Feed screw nut drive saddle and lower skateboard move with respect to the bed body knife bar are stretched into the differential carrier intracoelomic cavity, and be fixed on molding cutter on the knife bar this moment again, could process the sphere of differential carrier intracoelomic cavity then; Also need after the processing to unload cutter in the cavity again; The both sides machined surface of inner chamber is also wanted tool changing processing, and operation is many, complex operation; Long processing time; Processing cost is high, the more important thing is because the multiple clamping cutter can't guarantee machining accuracy, thus the poor product quality after the processing.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting the scope of the utility model.
With reference to figure 1: a kind of numerical control car inner chamber sphere device; Comprise knife rest 9 and main shaft; Wherein, Also comprise knife bar 2; Screw rod 4 and motor 5; Knife bar 2 is provided with cutter spare 8 cutter spares 8 upper ends and is arranged at gear; Cutter spare 8 lower ends are provided with lathe tool 7; Have a screwed hole on the described knife bar 2, described screw rod 4 one ends place in the screwed hole, and described motor 5 is connected with screw rod 4; Knife bar 2 upper surfaces are provided with rack bar 3; Rack bar 3 is slidingly connected with knife bar 2, and the tooth portion of an end of described rack bar 3 and the gear 1 of cutter spare 8 are connected with a joggle, and the other end of rack bar 3 is connected with screw rod 4.
With reference to figure 1, specifically, the position of lathe tool cutter spare 8 is adjusted on the axis of knife bar 2 inside that this makes knife bar 2 get into housings.The planker that adds the lathe in man-hour moves to left and makes knife bar 2 get into the inside of housings, and will confirm suitable position this moment: like 01 time-out, then stepper motor 5 is just changeing rack bar 3 reach driven gears 1 is rotated, and lathe tool 7 levels is threaded to stop (B point about 45 degree as schemes).Lathe carriage continues to move to left to 02 and stops, and lathe spindle begins rotation, and stepper motor 5 is just changeing (worker advances) to be rotated tooth bar reach driven gear 1 to realize that turning is machined to the C point, and main shaft stops.Move behind the stepper motor 5 counter-rotating tooth bars 3 and make lathe tool 7 to B points, then planker moves right apart from e, and stepper motor 5 counter-rotatings simultaneously stop lathe tool to A point.Lathe carriage continues to move to right and shifts out the housing appropriate location to knife bar 2 and stop, and promptly accomplishes the processing of sphere.
The above only is the utility model preferred implementation; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why; Can also make some improvement and modification, these improvement and modification also should be considered as the protection domain of the utility model.
