Abstract
The invention discloses an ejector pin pivot for batch machining of sheet gears. The ejector pin pivot comprises a headstock ejector pin, a core bar, a discharge sleeve, a tailstock ejector pin, a lifting pin and a set screw, wherein, the headstock ejector pin is arranged on a headstock spindle of an automatic hobbing machine; the core bar, the lifting pin and the set screw are arranged in the tailstock ejector pin; one end of the lifting pin props against the core bar, and the other end of the lifting pin is propped against the set screw; the tailstock ejector pin is arranged on a tailstock of the automatic hobbing machine; and the discharge sleeve is sheathed on a headstock of the automatic hobbing machine and is sheathed on the tailstock ejector pin. The ejector pin pivot has the advantages of simple design and high positioning accuracy, and is easy to manufacture, thus meeting the requirement for coaxiality between pitches and inner bores of the sheet gears, and improving batch machining efficiency; and as the pivot is damageable, the pivot is made into a detachable part so as to facilitate replacement, and meanwhile the pivot can be assembled reliably and is flexible and convenient in use.
Description
Technical field
The present invention relates to machining equipment, relate in particular to a kind of thimble mandrel of batch machining plate gear.
Background technology
In machinery, the consumption of web gear is very big, but because workpiece is thinner, yield rate is very low when the processing tooth, and we just consider the stack of gear embryo is conspired to create string, have not only increased the thickness of workpiece, and have formed batch machining.
Summary of the invention
The objective of the invention is provides a kind of thimble mandrel of batch machining plate gear in order to overcome the problem that existing processing web gear exists.
The thimble mandrel comprises headstock thimble, plug, discharging cover, tailstock thimble, ejector pin and marks closely screw; Headstock thimble is installed on the headstock spindle of automatic hobbing machine, plug, ejector pin, mark closely screw and all be contained in the tailstock thimble, ejector pin one end heads on plug, the ejector pin other end is marked closely screw and is headed on, the tailstock thimble is installed on the tailstock of automatic hobbing machine, discharging is sleeved on the headstock of automatic hobbing machine, and is enclosed within on the tailstock thimble.
Positioning accuracy height of the present invention has guaranteed the requirement of plate gear pitch circle and centre bore axiality, forms batch machining and has improved efficient, because mandrel is a consumable accessory, makes detachablely, be convenient to change, and clamping is reliable, uses flexibly, convenient.
Description of drawings
The structural representation of Fig. 1 thimble mandrel;
Among the figure: headstock thimble 1, plug 2, discharging cover 3, tailstock thimble 4, pin 5 and mark closely screw 6.
The specific embodiment
As shown in Figure 1, the thimble mandrel of batch machining plate gear comprises headstock thimble 1, plug 2, discharging cover 3, tailstock thimble 4, ejector pin 5 and marks closely screw 6; Headstock thimble 1 is installed on the headstock spindle of automatic hobbing machine, plug 2, ejector pin 5, mark closely screw 6 and all be contained in the tailstock thimble 4, ejector pin 5 one ends head on plug 2, ejector pin 5 other ends are marked closely screw 6 and are headed on, tailstock thimble 4 is installed on the tailstock of automatic hobbing machine, discharging cover 3 is contained on the headstock of automatic hobbing machine, and is enclosed within on the tailstock thimble 4.
Headstock thimble 1 is the cover parts of a hollow, is installed on the headstock spindle of automatic hobbing machine, by four installing holes on it, fix tightly; Plug 2, ejector pin 5, mark closely screw 6 and all be contained in the tailstock thimble 4, plug 2 is the thick axial workpieces of the thin end of an end, a thin end diameter is relevant with the centre bore size of the plate gear that will process, a thick end and the internal diameter of tailstock thimble 4 are complementary, it stretches out the length L of tailstock thimble 4 by thickness of workpiece and material decision, being no more than 17mm generally speaking, is 14mm because the YZM3602 automatic hobbing machine requires maximum lamination length, and its thick end contacts with ejector pin 5; Ejector pin 5 is cylinders, at plug 2 with mark closely between the screw 6, is marked closely jail, screw 6 top; Tailstock thimble 4 is sleeve parts of a hollow, and an end of centre bore has internal thread, is used for loading oncomelania nail 6, and four installing holes are arranged on its convex edge, is installed in by the screw of packing on the tailstock of automatic hobbing machine; Discharging cover 3 is cover parts of a band crank, and crank end is contained on the headstock of automatic hobbing machine, and the lasso end is contained on the tailstock thimble 4; Marking closely screw 6 is flat-top screws of hexagonal in the band.
The course of work of this device: when the processing plate gear, earlier with plug 2, ejector pin 5, mark closely screw 6 and pack into successively in the tailstock thimble 4, and tighten and mark closely screw 6, then with headstock thimble 1, tailstock thimble 4 is installed on the headstock and tailstock spindle of automatic hobbing machine by screw respectively, and correction puts in place.The gear embryo that the manipulator that starts automatic hobbing machine will conspire to create string deliver to headstock thimble 1 and tailstock thimble 4 between center line on, tailstock spindle advances, drive tailstock thimble 4, plug 2 is inserted in the centre bore of lamination gear, and enter 2～3mm place in the centre bore of headstock thimble 1, at this moment lamination gear indusium is located, start automatic hobbing machine and begin to add work gear, after processing a string workpiece, tailstock spindle is return, and tailstock thimble 4 withdraws from thereupon, and discharging cover 3 stops that the lamination gear moves with plug 2, be removed from plug 2, fall into following hopper.Manipulator again the gear embryo of bunchiness is delivered to headstock thimble 1 and tailstock thimble 4 between center line on, descend a string processing.Each processing is a string, and a string have 10 to 20, and what of quantity are relevant with the thickness of plate gear.
