The axis of described top center line and described inflatable sleeve is on same straight line.
Described sleeve block is cylindrical or square, thereafter end face is provided with the spacing hole that is used for the gear shaving machine butt, when needing shaving, workpiece adds man-hour, earlier processing work is enclosed within on the inflatable sleeve of elastic shaft sleeve front portion, the sleeve block of elastic shaft sleeve is installed on the gear shaving machine, regulate elastic shaft sleeve and top horizontal throw by gear shaving machine, when top conical tip is inserted in the inflatable sleeve, the inflatable sleeve that has groove will expand outwardly, make the outer wall of inflatable sleeve and the inwall interference butt of processing work, the boss at elastic shaft sleeve middle part and the sidewall of trim ring clamp processing work simultaneously.A set ring annular groove is mainly the inflatable sleeve space of giving up the throne is provided between annular boss and inflatable sleeve, when in the top insertion elastic shaft sleeve, the elastic shaft sleeve of fluting will push backward, to guarantee the tight butt of inflatable sleeve and processing work.
For the processing work of different size, can regulate the fixed position of processing work by the extruding elastic parts, also can rotate nut, be suitable for different processing works by the position that changes nut.
After workpiece machines, withdraw from elastic shaft sleeve by gear shaving machine, make top tip from the inflatable sleeve, extract, the elastic shaft sleeve of distending shrinks automatically, and processing work then can take out easily.
Also be set with packing ring and spring washer on the described top axostylus axostyle, its middle washer is between nut and elastic parts, spring washer is between described nut and top side elevation, and described packing ring and spring washer mainly are to open cushioning effect when gear shaving machine is worked, and reduces mechanical wear.
Have limited impression on described top axostylus axostyle, be installed with dog screw on the described trim ring, this dog screw stretches into described limited impression and connects with axostylus axostyle, prevents to cause the landing of trim ring because of the horizontal movement of lathe or become flexible.
Also be provided with the circular groove of a circle on the front end face of annular boss, this circular groove equates with the radius of described inflatable sleeve.One circle circular groove is set on the front end face of boss, mainly be to avoid the processing work edge burr phenomena to occur, make the maintenance inaccuracy, groove is set, make the burr of processing work edge can fall into groove, guarantee that the processing work sidewall and the boss sidewall of elastic shaft sleeve and the sidewall of trim ring fit tightly, make the workpiece location more firm.
Described elastic parts is a butterfly spring, the convenient installation, and elastic parts also can be selected common spring.
Remarkable result of the present utility model is: a kind of Fixture for Gear-shaving is provided, the not smart shortcoming in location that adopts the elastic shaft sleeve of slotting to avoid the processing work internal diameter size to change and cause, by the elastic parts between the seating surface is set, make processing work fixing more reliable, improved the quality of converted products; When processing a workpiece, only need the control lathe just can realize the installation and the unloading of processing work, reduced the manpower consumption, improved operating efficiency.
