Description

A kind of decile groove milling attachment

Technical field

The utility model belongs to mechanical field, relates in particular to a kind of decile groove milling attachment.

Background technology

During originally with minute groove such as milling machine milling, without special tooling, the following method of general employing: the outer surface that clamps workpiece to be machined with milling machine dividing head, after centering milling cutter and dividing head centre, start milling the first groove, shake dividing head rotary handle, once often shake a circle workpiece rotation, shake corresponding number of turns milling the second groove, by that analogy all the other decile grooves of milling.Each decile groove of milling needs long-time multi-turn number to shake dividing head handle, and when dividing head clamps in addition, thin-wall workpiece is very easily out of shape, and can have a strong impact on machining accuracy, operates like this that labour intensity is large, production efficiency is low and low precision.

Summary of the invention

The utility model provides a kind of decile groove milling attachment, solved that manual setting method labour intensity in background technology is large, low precision, shortcoming that production efficiency is low.

The technical solution of the utility model is achieved in that a kind of decile groove milling attachment, comprise base, on base, by lock-screw, be equipped with index dial, in the stomidium of base both sides, be respectively equipped with spacer pin I and spacer pin II, base two ends are fixedly equipped with respectively anti-turn screw, anti-turn screw front end inserts in the axial elongated slot of spacer pin I and spacer pin II, in spacer pin I and spacer pin II, be all equipped with spring I, spring I upper end is provided with adjustment screw, spacer pin I and spacer pin II one end are with gradient sharp tooth, and insert in the groove of index dial, spacer pin I and spacer pin II and index dial floating connection, index dial is fixedly connected with axle body by key, axle body is fixedly connected with resilient sleeve by trip bolt, axle body is by spring II and compression tapered sleeve floating connection, compress in tapered sleeve and be provided with housing screw, rotating disk is by two baffle plates and neck bush and axle body floating connection, baffle plate and the nut in outside, locking nut is fixedly connected with,

Compress between tapered sleeve and housing screw and be provided with packing ring;

Handle is fixedly connected with rotating disk.

The beneficial effects of the utility model are: the utility model is easy to operate, and precision is high, and labour intensity is low, and operating efficiency is high, process different equal indicative workpiece and only need change index dial.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described: a kind of decile groove milling attachment, comprise the base 1 being fixedly mounted on milling machine table, on base 1, by lock-screw 7, be equipped with index dial 6, in the stomidium of base 1 both sides, be respectively equipped with spacer pin I 2 and spacer pin II 21, base 1 two ends are fixedly equipped with respectively anti-turn screw 5, anti-turn screw 5 front ends insert in the axial elongated slot of spacer pin I 2 and spacer pin II 21, prevent that spacer pin from rotating, in spacer pin I 2 and spacer pin II 21, be all equipped with spring I 4, spring I 4 upper ends are provided with adjustment screw 3, spacer pin I 2 and spacer pin II 21 one end are with gradient sharp tooth, and insert in the groove of index dial 6, spacer pin head is with gradient sharp tooth, not only can limit index dial 6 rotations but also can drive index dial 6 to rotate, while rotating counterclockwise handle 22, spacer pin II 21 in handle is rotated with handle 22, because spacer pin head is to insert in the groove of index dial 6 with gradient sharp tooth (anti-reversing shape), drive index dial 6 to rotate counterclockwise, spacer pin I 2 and spacer pin II 21 and index dial 6 floating connections, index dial 6 is fixedly connected with axle body 12 by key 20, axle body 12 is fixedly connected with resilient sleeve 13 by trip bolt 14, axle body 12 is by spring II 15 and compression tapered sleeve 16 floating connections, compress in tapered sleeve 16 and be provided with housing screw 18, compress between tapered sleeve 16 and housing screw 18 and be provided with packing ring 17, rotating disk 11 is by two baffle plates 10 and neck bush 19 and axle body 12 floating connections, baffle plate 10 and the nut 9 in outside, locking nut 8 is fixedly connected with, adjusting nut 9, the end play of the adjustable index dial 6 of locking nut 8 and rotating disk 11 and each connector, guarantee to rotate freely, handle 22 front ends screw on rotating disk 11 and are processed with in threaded interior hole.
