Abstract

The invention belongs to the technical field of manufacturing of aviation and automobile process equipment and provides a scribing spring graver special for a numerical control machine tool. The scribing spring graver comprises a sleeve 3 which is clamped in a spring clip of a graver handle 2, a step is arranged at the front end of an inner cavity of the sleeve 3, and the back portion of the inner cavity of the sleeve 3 is provided with a thread; an adjusting screw 7 is in threaded connection with the interior of the inner cavity of the sleeve 3 from the back portion of the sleeve 3, and the tail of a graver head 4 extends into the inner cavity of the sleeve 3 from the front portion of the sleeve; a spring 6 is installed in the middle of the inner cavity of the sleeve 3, and the tail of the graver head 4 is provided with a step; after a check ring 5 is arranged at the tail of the graver head 4 in a sleeving mode, the spring 6 is located in the middle of the inner cavity of the sleeve 3, the front end of the spring 6 abuts against the rear surface of the check ring 5, and the rear end of the spring 6 abuts against the front surface of the adjusting screw 7; symmetrical waist-shaped keyways are formed in the side surfaces of the sleeve 3, and symmetrical sliding double keys 9 are arranged in the side direction of the graver head 4, extend into the waist-shaped keyways and are capable of moving front and back in the waist-shaped keyways in the axial direction. The scribing spring graver is used for the numerical control machine tool to carve and draw figure lines and engrave and mill character markers.

Description

The special line spring icking tool of numerically-controlled machine

Technical field

The invention belongs to aviation, automobile technology equipment manufacturing technical field, it relates to a kind of special line spring icking tool of numerically-controlled machine.

Background technology

At present, domestic and international aviation, automobile technology equipment manufacturing technical field, a large amount of use numerically-controlled machine equipment, tooling surface needs delineation figure line, carving milling word marking, and the usual degree of depth of figure line, word marking is 0.06mm to 0.08mm. Delineation figure line, carving milling word marking need cutter high speed rotating and with machine tool chief axis other direction of principal axis move forward into.

Summary of the invention

It is an object of the invention to: a kind of special line spring icking tool of numerically-controlled machine is provided, delineate figure line, carving milling word marking for numerically-controlled machine.

The technical scheme of the present invention is:

A kind of special line spring icking tool of numerically-controlled machine, comprising:

Sleeve 3, described sleeve 3 is stuck in the Spring Card of handle of a knife 1, and sleeve 3 inner chamber front end is provided with step, and sleeve 3 inner chamber rear portion is provided with screw thread, set screw 7 is screwed onto sleeve 3 inner chamber from rear, the afterbody of cutter head 4 stretches into sleeve 3 inner chamber from front, in the middle part of sleeve 3 inner chamber, spring is housed, and cutter head 4 afterbody is provided with step, after back-up ring 5 is enclosed within the step of cutter head 4 afterbody, spring 6 is positioned in the middle part of sleeve 3 inner chamber, and spring 6 front end withstands on back-up ring 5 rear surface, and spring 6 rear end withstands on set screw 7 front surface; Sleeve 3 side has the strong groove of symmetrical waist type, and cutter head 4 side direction is provided with symmetrical slip two strong 9, and described slip two strong 9 is stretched into the strong groove of described waist type and can be moved forward and backward vertically in the strong groove of waist type.

It is an advantage of the invention that:

1 is axially compensated automatically by cutter head, when making cutter head run into " height " point at work, avoided profoundly cutting, thus protects cutter head unlikely impaired;

2 pass through cutter head axially compensates automatically, when making cutter head run into " height " point or " low " point at work, remains even depth of cut, thus reaches the object of workpiece line width, uniform depth;

3 by the built-in initial tension of spring of adjustment, adapts to unlike material workpiece surface groove, carving milling word marking, reaches desirable line width, the degree of depth.

Fig. 1 is scheme of installation of the present invention.

Fig. 2 is local structure schematic diagram one of the present invention.

Fig. 3 is local structure schematic diagram two of the present invention.

Fig. 4 is local structure schematic diagram three of the present invention.

Fig. 5 is working state schematic representation of the present invention.

Embodiment

The present invention provides a kind of special line spring icking tool of numerically-controlled machine, as Figure 1-5, comprising:

During use, as shown in Figure 2, according to workpiece material, can regulating built-in initial tension of spring by screwing out or screw in set screw, initial tension of spring is acted on the cutter head shaft shoulder by back-up ring. As shown in Figure 4, slip double bond is fixedly connected with after being press-fitted with cutter head, and slip double bond and cutter head can slide relative to sleeve trace in sleeve simultaneously vertically. During off working state, by initial tension of spring effect, slip double bond and cutter head are extruded to sleeve sliding keyway one end. When sleeve rotates, the rotary motion of sleeve is delivered to cutter head by slip double bond. As shown in Figure 5, when the special line spring icking tool of numerically-controlled machine runs into workpiece profile degree error on mobile feed-paths, cutter head is by axial counter-force effect, the built-in spring of reverse extrusion, slip double bond and cutter head lift automatically, compensate workpiece profile degree error, reach the object of adjustment line width, the degree of depth. As Fig. 4 shows institute, the special line spring icking tool of numerically-controlled machine mates mutually with numerically-controlled machine standard accessonies BT50M2 handle of a knife, it is not necessary to increase other annexes, identical with rigidity milling cutter installation way.
