Abstract

A machining device for a Morse inner taper shank cutter. The traditional machining method of the Morse taper shank cutter has the defects that the quenching deformation of the heat treatment is difficult to control, the end jump and the diameter jump of the cutter end are difficult to guarantee, and the rejection rate is higher. A machining device for a Morse inner taper shank cutter comprises a cutter handle main body (1) and a Morse taper sleeve (2), wherein the Morse taper sleeve is located in the cutter handle main body and is sleeved outside a Morse shank cutter end (8), a belleville spring (3) is fixed between the right end face of the Morse taper sleeve and the cutter handle main body, a blind rivet (4) penetrates through an inner cavity (13) formed in a tapered end (10) of the right end face of the cutter handle main body, the left end of the blind rivet is in threaded connection with the right end face of the Morse shank cutter end, a plurality of positioning threaded holes (11) are formed in the circumference of the tapered end, a locking screw (7) is connected to each positioning threaded hole in an internal thread mode, and the locking screw is inserted into a taper groove face of the blind. The utility model is used for the processing of morse taper shank cutter.

Description

Machining device for Morse inner taper shank cutter

The technical field is as follows:

the utility model relates to a high accuracy fixture device, concretely relates to processingequipment of interior taper shank cutter of morse.

Background art:

morse taper is an international universal standard for taper for precise location of an interference fit. The biggest benefit of taper fit is good centering, and the position at work piece center is not influenced after the work piece is freely dismantled, the clamping of being convenient for very much is dismantled. The morse taper is classified into 0-6, and the morse taper is often used for a spindle hole of a machine tool, machine tool accessories, cutter bars of various tools, and the like.

Generally, the machining method of the Morse taper shank type indexable cutter is that a taper sleeve is arranged on the Morse taper shank or the end of the Morse taper shank is turned into a cylinder, an insert groove is machined by clamping the taper sleeve or the cylinder part, namely the cutter end is generally machined before fire, and then the taper shank part is finely ground through heat treatment. The processing method has the defects that the heat treatment quenching deformation is not easy to control, the end jump and the diameter jump of the cutter end are not easy to guarantee, and the rejection rate is higher.

In addition, because the Morse taper shank type cutting tools have a plurality of specifications and length series, a single clamp can not meet the processing requirement.

The invention content is as follows:

the utility model aims at providing an anchor clamps of clamping convenience, positioning dimension invariant, the fire post-processing of being convenient for, high accuracy.

The above purpose is realized by the following technical scheme:

the machining device for the Morse inner taper shank cutter comprises a cutter handle main body and a Morse taper sleeve, wherein the Morse taper sleeve is located in the cutter handle main body, the Morse taper sleeve is sleeved outside the Morse shank cutter end, a butterfly spring is fixed between the right end face of the Morse taper sleeve and the cutter handle main body, a blind rivet penetrates through an inner cavity formed in the tapered end of the right end face of the cutter handle main body, the left end of the blind rivet is in threaded connection with the right end face of the Morse shank cutter end, a plurality of positioning threaded holes are formed in the circumference of the tapered end, each positioning threaded hole is in threaded connection with a locking screw, and the locking screw is inserted into a taper groove face of the blind rivet.

According to the machining device for the Morse inner taper shank cutter, a fixing threaded hole is formed in the side plane of the cylindrical end of the shank main body, a fastening screw is connected to the fixing threaded hole in an internal thread mode, and the bottom surface of the fastening screw is clamped on the side plane of the Morse taper sleeve.

According to the machining device for the Morse inner conical handle cutter, a round hole is formed in the circumferential surface of the conical end of the right end face of the cutter handle main body, a cylindrical pin is inserted into the round hole and positioned at the end of the Morse inner conical handle cutter

Has the advantages that:

1. the utility model discloses the device adopts handle of a knife main part and the split type structure of morse taper sleeve, has reduced the change handle of a knife main part many times, the error of artificial measuring standard.

The utility model discloses the general interchangeability of device is good, and different specifications are made according to different tapering numbers to morse taper sleeve, can only change morse taper sleeve and blind rivet just can process corresponding morse tapered cutter, need not change the handle of a knife main part.

Description of the drawings:

FIG. 1 is a front view of the present invention;

fig. 2 is a right side view of the present invention;

in the figure: 1. a knife handle main body; 2. a Morse taper sleeve; 3. a belleville spring; 4. pulling nails; 5. a cylindrical pin; 6. fastening screws; 7. locking the screw; 8. a morse shank cutter end; 9. a tapered groove surface; 10. a tapered end; 11. positioning the threaded hole; 12. fixing the threaded hole; 13. an inner cavity.

The specific implementation mode is as follows:

example 1:

the machining device for the Morse inner taper shank cutter comprises a cutter handle main body 1 and a Morse taper sleeve 2, wherein the Morse taper sleeve is located in the cutter handle main body, the Morse taper sleeve is sleeved outside the Morse taper shank cutter end 8, a butterfly spring 3 is fixed between the right end face of the Morse taper sleeve and the cutter handle main body, a blind rivet 4 penetrates through an inner cavity 13 formed in a tapered end 10 of the right end face of the cutter handle main body, the left end of the blind rivet is in threaded connection with the right end face of the Morse taper shank cutter end, a plurality of positioning threaded holes 11 are formed in the circumference of the tapered end, the threaded holes are arranged in a staggered mode, a locking screw 7 is connected to the inner threads of each positioning threaded hole, and the locking screw is inserted into a taper groove face of the blind rivet.

As shown in fig. 1, when adjustment morse taper sleeve right-hand member face and handle of a knife main part internal clearance, adjust through the pulling blind rivet, the blind rivet produces axial tension, taut morse handle cutter end 8, locking screw and positioning screw hole screw-thread fit, the bottom surface is inserted in the taper groove face of blind rivet, as shown in the figure, the locking screw top on upper portion is on the right side of taper groove face, the locking screw top of lower part is on the left side of taper groove face, just so realized the fixed of blind rivet, set up restriction morse handle cutter end axial position through the cylindric lock, the side plane at morse taper sleeve is pushed up to fixed screw hole female connection's fastening screw bottom surface, can fix morse taper sleeve, only need change morse taper sleeve can, need not change the handle of a knife main part.
