Specific embodiment
To make the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this practicality
New specific embodiment is described in further detail.
Shown in reference picture 1, the present embodiment internal expansion type scraper includes bulging bar 1, elastic cutter holder 2, stop collar 3 and holding screw
4。
Shown in reference picture 2, the right-hand member of bulging bar 1 is the first Handheld Division, and without hardness requirement, left end has been the work of bulging effect
Portion, the cylindrical upper processing long striped groove in the middle part of bulging bar 1, the length direction of long striped groove is axially parallel with bulging bar 1.Bullet
Property cutter holder 2 and after holding screw 4 is arranged on bulging bar 1, in the end of holding screw 4 insertion long striped groove, to limit bullet
Property cutter holder rotate in a circumferential direction, axially simultaneously length controls its shift motion, i.e., by holding screw 4, the elastic cutter holder 2 of control is relative
The stroke of bulging bar 1 and relative rotation.
The left end head of bulging bar 1 be outer cone head part, the present embodiment set cone angle be 50 °, its hardness requirement HRC58~
Between 62, for strutting elastic cutter holder.
Stop collar 3 is set on bulging bar 1, between long striped groove and the first Handheld Division.
Shown in reference picture 3, the right-hand member of elastic cutter holder 2 is the second Handheld Division, on the cylindrical arbitrarily angled circumference in the second Handheld Division
One radial direction internal thread hole of processing, installs holding screw 4 in internal thread hole, after elastic cutter holder 2 is assembled with bulging bar 1, clamp screw
Nail 4 is fixed in the long striped groove of bulging bar 1.Elastic cutter holder 2 is along central shaft to opened hole, and elastic cutter holder 2 is logical by this
Borehole jack is located on bulging bar 1, positioned at the left side of stop collar 3.
Through hole includes straight hole and the internal taper hole positioned at left end head, and internal taper hole is engaged with the outer cone head part of bulging bar, this reality
Apply example and internal taper hole is set to 70 ° of internal taper holes, with the 50 ° of taper fit motions of bulging bar, serve and strut.In addition, in elastic blade
The left end work department of folder 2, is provided with the cross recess with gap vertically, and the length of cross recess is the 40% of elastic cutter holder total length
~60%, preferably 50%, so, elastic blade chuck portion is bisected into the quartering, and each decile is taper cutter tooth, in elastic cutter holder 2
Left end forms a Phillips-type and can rise formula taper cutter tooth, and tapered knife addendum angle is 90 °, anterior angle is 0 °, relief angle is 12 °.
Shown in reference picture 4, through hole is processed at the center of stop collar 3, and aperture is cylindrical with bulging bar 1 to be engaged, and plays position-limiting action.
When using, stop collar 3 is enclosed within support bar 1 first, then by the elastic cutter holder 2 of left end insertion of bulging bar 1
In through hole, during holding screw 4 screwed in into the handle part internal thread hole of elastic cutter holder 2, it is fixed in bulging bar long striped groove, prevents
Only bulging bar 1 and the mutual rotation and disengaging of elastic cutter holder 2, the first Handheld Division of bulging bar 1 is held into the palm of the hand, and two fingers catch on
Second Handheld Division of elastic cutter holder 2, the insertion of the left end cutting tip of elastic cutter holder 2 need to be gone in the hole in piece part of flash removed, and finger is slow
Slowly pull back the second Handheld Division of elastic cutter holder 2, the left end external taper part of bulging bar 1 is pressed into the elastic left end internal taper hole of cutter holder 2, with
Finger constantly to pull back, bulging bar 1 is further moved to right, make the taper cutter tooth spreading of the left end of elastic cutter holder 2, be pulled to elastic cutter holder 2
The second Handheld Division contacted with stop collar 3, the left end taper cutter tooth of elastic cutter holder 2 rises to maximum, at this moment, scraper is integrally pulled back,
The taper cutter tooth of the left end of elastic cutter holder 2 is set to be contacted with aperture, and the internal expansion type scraper that integrally turns clockwise, you can realize to aperture
The removal of burr.After removal, two fingers decontrol the second Handheld Division of elastic cutter holder 2, and the left end outer cone bar part of bulging bar 1 is from elasticity
Exited in the internal taper hole of the left end of cutter holder 2, the taper cutter tooth of the left end spreading of elastic cutter holder 2 recovers to normal condition, at this moment, you can will
Elastic toolholder portion takes out from hole in piece part, completes the process of aperture deburring.
By above-mentioned technical proposal as can be seen that the utility model simple structure, easy to operate, laborsaving, can realize to deeper
Orifice part, the particularly removal of closing space aperture burr.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model know-why is not departed from, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
