Abstract

The utility model relates to a gear hobbing clamp which comprises a conical casing and a tail stock which can be adjusted outward. An elastic clamp sleeve and a transition sleeve are arranged in the conical casing; the elastic clamp sleeve is connected with the transition sleeve through threads; a guiding screw and an adjusting screw are arranged on the conical casing; a cross block with a cross sleeve is arranged in the tail stock; a push rod is arranged on the tail stock; the transition sleeve is connected with the conical casing through a tightening bolt; and the conical casing and the tail stock are tightly fixed into a whole through a connecting screw. The gear hobbing clamp has a simple structure and low manufacturing cost, and is convenient to disassemble; and the gear machining accuracy can be ensured, and for workpieces with different sizes, the only thing to do is to change the elastic clamp sleeves with corresponding sizes, the changing time is short, the machining efficiency of gears is improved, and the manufacturing cost of the gears is reduced.

Description

The gear hobbing anchor clamps

Technical field

The utility model relates to a kind of anchor clamps, specifically relates to a kind of gear gear hobbing anchor clamps.

Background technology

Gear hobbing is the basic operation of Gear Processing, adopts to roll and shaves the processes gear, and the gear hobbing precision plays a decisive role to the final precision of gear, generally adopts Digit Control Machine Tool to add work gear at present, effectively raises the machining accuracy and the working (machining) efficiency of gear.But present numerical control gear hobbing clamp structure complexity, required precision height, involve great expense, loading and unloading are inconvenient; Process the gear of different size simultaneously, need the anchor clamps of different size, the time of changing anchor clamps is long, also causes the manufacturing expense height of gear, is unfavorable for that fast quick change produces.

Summary of the invention

The purpose of this utility model is the shortcoming that overcomes prior art, and the gear hobbing anchor clamps that a kind of simple in structure, easy to manufacture, easy to loading and unloading, replacing time is short, the Gear Processing cost is low are provided.

Gear hobbing anchor clamps of the present utility model comprise conical shell and the dead head of can transfering to other localities, and it is characterized in that being provided with elastic jacket and spacer shell in the described conical shell, and elastic jacket and spacer shell are threaded, and conical shell is provided with guider screw and adjusts screw; Can transfer to other localities is provided with the cross piece of band cross cover in the dead head, and the dead head of can transfering to other localities is provided with push rod; Spacer shell is connected by turnbuckle with conical shell; The conical shell and the dead head of can transfering to other localities are tightened up by attachment screw and are one.

Gear hobbing clamp structure of the present utility model is simple, low cost of manufacture, easy to loading and unloading; Can guarantee the Gear Processing precision, for the workpiece of different size, only need to change the elastic jacket of correspondingly-sized, the replacing time is short, has improved the working (machining) efficiency of gear, has reduced the manufacturing cost of gear.

Accompanying drawing is a structural representation of the present utility model.

Among the figure 1, elastic jacket, 2, conical shell, 3, guider screw, 4, spacer shell, 5, push rod, 6, the dead head of can transfering to other localities, 7, turnbuckle, 8, the cross piece, 9, the cross cover, 10, pull bar adapter sleeve, 11, hold-down screw, 12, adjust screw, 13, attachment screw.

The specific embodiment

Below in conjunction with accompanying drawing and example the utility model is done detailed description.

Gear hobbing anchor clamps of the present utility model comprise the conical shell 2 and the dead head 6 of can transfering to other localities, and are provided with elastic jacket 1 and spacer shell 4 in the conical shell 2, and elastic jacket 1 and spacer shell 4 are threaded, and conical shell 2 is provided with guider screw 3 and adjusts screw 12; Can transfer to other localities is provided with the cross piece 8 of band cross cover 9 in the dead head 6, and the dead head 6 of can transfering to other localities is provided with push rod 5; Spacer shell 4 is connected by turnbuckle 7 with conical shell 2; The conical shell 2 and the dead head 6 of can transfering to other localities are tightened up by attachment screw 13 and are one.

Only need the cross cover 9 of gear hobbing anchor clamps and the pull bar adapter sleeve 10 centerings embedding mouth of lathe oil cylinder during installation, angle of gear hobbing anchor clamps rotation just can be finished connection, be fixed on the platen by hold-down screw 11, workpiece inserts in the elastic jacket 1, by guider screw 3 with adjust screw 12 and adjust the axiality that can transfer to other localities between dead head 6 and the conical shell 2, the cross cover of the pull bar adapter sleeve 10 of lathe oil cylinder and gear hobbing anchor clamps 9 is fixed on workpiece in the elastic jacket 1 by turnbuckle 7.Workpiece completion of processing, the pull bar adapter sleeve 10 of lathe oil cylinder with the push rod 5 on the cross of gear hobbing anchor clamps cover 9, the dead head 6 of can transfering to other localities, spacer shell 4 and elastic jacket 1 jack-up upwards, are unclamped workpiece successively.

When diameter of work not simultaneously, only need to change a correspondingly-sized elastic jacket 1 and get final product.
