Description

Decile groove milling attachment

Technical field

The invention belongs to mechanical field, relate in particular to 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 the milling machine dividing head, start milling the first groove after centering milling cutter and dividing head centre, shake the 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 the dividing head handle, and when dividing head clamps in addition, thin-wall workpiece very easily is 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 invention provides a kind of decile groove milling attachment, solved that manual setting method labour intensity in the background technology is large, low precision, shortcoming that production efficiency is low.

Technical scheme of the present invention is achieved in that decile groove milling attachment, comprise base, be equipped with index dial by lock-screw on base, be respectively equipped with spacer pin I and spacer pin II in the stomidium of base both sides, the base two ends fixedly are equipped with respectively anti-turn screw, the anti-turn screw front end inserts in the axial elongated slot of spacer pin I and spacer pin II, all be equipped with the spring I on spacer pin I and spacer pin II, 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 the axle body by key, the axle body is fixedly connected with resilient sleeve by trip bolt, the 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 the 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 invention has the beneficial effects as follows: the present invention is easy to operate, and precision is high, and labour intensity is low, and high efficiency is processed different equal indicative workpiece and only need be changed index dial and get final product.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described: decile groove milling attachment, comprise the base 1 be fixedly mounted on milling machine table, be equipped with index dial 6 by lock-screw 7 on base 1, be respectively equipped with spacer pin I 2 and spacer pin II 21 in the stomidium of base 1 both sides, base 1 two ends fixedly are 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, all be equipped with spring I 4 on spacer pin I 2 and spacer pin II 21, spring I 4 upper ends are provided with adjustment screw 3, spacer pin I 2 and spacer pin II 21 1 ends are with gradient sharp tooth, and insert in the groove of index dial 6, the 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 the 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 the outside, locking nut 8 is fixedly connected with, adjusting nut 9, locking nut 8 can be regulated the end play of index dial 6 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.

Workpiece is contained in resilient sleeve 13, workpiece is located on resilient sleeve 13 and axle body 12 with endoporus and end face, tighten housing screw 18, interior male cone (strobilus masculinus) by compressing tapered sleeve 16 and resilient sleeve 13 is from endoporus swelling workpiece, first unclamp lock-screw 7 during calibration, handle 22 respective angles turn left, under the fixation of spacer pin I 2, the conical surface of spacer pin II 21 slides along the conical surface of index dial 6, the groove that makes spacer pin II 21 overcome spring force disengagement index dial 6 enters in next groove, respective angles again turns right handle 22, under the fixation of spacer pin II 21, spacer pin I 2 is under the rotary actuation of index dial 6, overcoming spring force throws off former indexing trough and enters in the next groove turned over, complete calibration one time, tightening lock-screw 7 can be processed, unclamp housing screw 18 after all groove completion of processing, under 15 effects of spring II, compressing tapered sleeve 16 is upspring, resilient sleeve 13 is shunk, tension force disappears, can easily change workpiece.
