Abstract

The utility model discloses a cutter bar with depth adjustable groove, comprising a main body of cutter bar. The utility model is characterized in that tail end of the cutter bar is inserted inside a shaft hole of a connecting pole through a driving button; the tail end of the cutter bar is sleeved in series with a cutting thrust spring and a spring adjusting nut; the top end of the cutter bar is sleeved in serial with an axial direction positioning sleeve, a depth adjusting slide sleeve and a depth adjusting nut; and the other end of the connecting pole is connected with a shaft output end of a combined device tool multi-shaft box. The utility model has the advantages of thrusting the cutter for cutting through the cutting thrust spring, compensating the residual between the processing positioning and the power slide table positioning through the compression of the cutting thrust spring; adjusting the distance t between the axial direction positioning sleeve and the blade of the cutting device through the depth adjusting nut; and making the cutting processing positioning plane of the axial direction positioning sleeve coincident with the size measuring benchmark plane to control the processing depth t. The utility model is combined with multi-shaft box of traditional combined device tool, thereby achieving the processing for groove and seam with depth requirement.

Description

The adjustable knife bar of cutting groove depth

Technical field

The utility model relates to a kind of metal cutting building-block machine knife bar, relates in particular to the adjustable control knife bar of a kind of cutting groove depth.

Background technology

Building-block machine not only requires control diameter D when processing seal groove or scraping seam, will control cutting groove depth size t toward contact, as shown in Figure 1, 2.Adopt traditional cutter and method,, therefore often need complicated unit head or machining center to finish for so processed structure because processing location benchmark and measuring basis disunity are difficult to control cutting groove depth size t.

Summary of the invention

To be solved in the utility model is the above-mentioned defective that prior art exists, provide a kind of cutting groove depth adjustable control knife bar, be intended to adopt simple structure to reach and regulate and control the distance of processing location benchmark and measuring basis, and then control cutting groove depth effectively.

The technical scheme that addresses the above problem employing is: the adjustable knife bar of cutting groove depth, comprise the knife bar body, the end that it is characterized in that described knife bar is plugged in the axis hole of an extension bar by driving key, suit cutting thrust spring and spring adjusting nut successively on it, the top of described knife bar is suit axial location cover, depth adjustment sliding sleeve and depth adjustment nut successively; The other end of described extension bar is connected to the building-block machine axles box and goes out axle head.

The utility model utilization cutting thrust spring advances Tool in Cutting, and by cutting the compression of thrust spring, error between compensation processing location datum level and lathe power slide location datum level, utilize described depth adjustment nut regulate between described axial location cover and cutting tool blade apart from t, the machining locating surface that described axial location is put overlaps with the dimensional measurement datum level, realizes the control of working depth t.The utility model and traditional building-block machine axles box combination can realize the groove of degree of depth requirement and the processing of seam.

Described axial location cover can be done relative revolution with described knife bar, and axially tightly links to each other with described depth adjustment cover and described depth adjustment nut by bearing.

As further improvement of the utility model, also be set with a bearing clearance adjusting nut in the junction of described axial location cover and depth adjustment sliding sleeve.

Further improve as of the present utility model, described depth adjustment sliding sleeve is connected with described knife bar by feather key again, carrying out can doing axially-movable when cutting groove depth is regulated, fixes by hold-down screw and knife bar after regulating end.

The specific embodiment

With reference to Fig. 3, the adjustable knife bar of cutting groove depth of the present utility model, comprise knife bar body 11, the end of described knife bar 11 is plugged in the axis hole 14 of an extension bar 1 by driving key 2, suit cutting thrust spring 3 and spring adjusting nut 4 successively on it, the top of described knife bar 11 is suit axial location cover 12, depth adjustment sliding sleeve 9 and depth adjustment nut 5 successively; The other end of described extension bar 1 is connected to building-block machine axles box 18 and goes out axle head.

When carrying out machining, knife bar 11 rotates, and axial location cover 12 does not rotate.

Described depth adjustment sliding sleeve 9 is connected with described knife bar 11 by feather key 7, and is carrying out can doing axially-movable when cutting groove depth is regulated, fixing with knife bar 11 by hold-down screw 6 after regulating end.Like this, adding man-hour, depth adjustment sliding sleeve 9 and knife bar 11 interlocks.Between described axial location cover 12 and depth adjustment sliding sleeve 9, be provided with bearing 10.Junction at described axial location cover 12 and depth adjustment sliding sleeve 9 is set with a bearing clearance adjusting nut 8.

Operation principle of the present utility model is as follows:

Cutting tool 15 is installed in termination, top at knife bar 11, because knife bar 11 links to each other with extension bar 1 by driving key 2, axially compressible spring 3 produces axial displacement, circumferentially can transmit the cutting moment of torque by driving key 2, utilizes spring thrust to advance cutting during cutting; Axial location cover 12 can relatively rotate with knife bar 11, and the machining locating surface 20 on it is t with the distance of cutter blade, can regulate its size by depth adjustment nut 5.The groove depth measuring basis face 13 of regulating workpiece to be machined 14 overlaps with cutter blade, as shown in Figure 4, begins processing.

When the Tool in Cutting degree of depth reaches t, machining location datum level 20 overlaps with measuring basis face 13, the control of the realization degree of depth, as shown in Figure 5, Ci Shi axial force is passed to main spindle box 18 at last by axial location cover 12, bearing 10, depth adjustment cover 9, depth adjustment nut 5, knife bar 11, spring adjusting nut 4 compression cutting thrust springs 3.Error can take place in the location of the axial location of building-block machine and axial location cover 12, and by the compression of cutting thrust spring 3, driving key 2 slides in the keyway 16 of extension bar 1 and is compensated.

What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
