Machining center boring cutter presetter
Technical field:
The utility model relates to a kind of Machining Technology field, particularly a kind of presetter of machining center hole boring cutter.
background technology:
Machining center is a kind of high efficiency in the modern mechanical manufacturing field, high-precision process equipment, can carry out automatic tool changer and processing according to the degree of setting in advance, and can carry out auto-compensation to tool length or radius, but the way automatically do not compensated at present for hole boring cutter, therefore when carrying out Boring, for the size of calibration hole boring cutter, rely on operator's experience, often want the expensive time.Though organic outer tool setting gauge on market, complex structure, expensive.
the utility model content:
The purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of simple in structure, easy to operate, economical and practical, can calibrate easily the tool setting device of hole boring cutter size.
Structure of the present utility model is: on cast iron surface plate, fix one with the measure-alike standard tapered sleeve of machining center hole boring cutter taper shank section, the large end of tapered sleeve upwards, parallel interval 50-60mm with the tapered sleeve center line and fix a column, on column, be equipped with one can upper and lower slip guide pin bushing, perpendicular to the column direction, a single pole micrometer laterally is housed in guide pin bushing.
The beneficial effects of the utility model are: simple in structure, easy to operate, economical and practical, can carry out easily the outer tool setting of machine.
the accompanying drawing explanation:
Accompanying drawing is the utility model cutaway view.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
On cast iron surface plate 1, fix one with the measure-alike standard tapered sleeve 2 of machining center hole boring cutter taper shank section, the large end of tapered sleeve 2 upwards, hole boring cutter rod 3 can be put into wherein easily, with tapered sleeve 2, fit tightly, with tapered sleeve Center Gap 50-60mm, fix a column 5, the column center is parallel with the tapered sleeve center, a guide pin bushing 6 is housed on principal post 5, guide pin bushing 6 is the upper and lower slip of energy on column, perpendicular to the column direction, a single pole micrometer 7 laterally is housed in guide pin bushing 6, the left side of micrometer 7 is near boring cutter 4.Can process the hole of several dress columns along the direction of column 5 every 30-50mm on dull and stereotyped 1, column can be packed in corresponding hole according to the boring cutter size.When the hole of processing work, general minute heavy boring and right boring two steps are carried out, when heavy boring, first on boring cutter bar, load onto boring cutter 4, leave in the situation of allowance for finish, go out with vernier caliper measurement the length that boring cutter should stretch out, install boring cutter, single pole micrometer 7 left sides are contacted with boring cutter, write down the scale value on micrometer, then taking off boring cutter bar 3 from tapered sleeve 2 installs on the machining center main shaft workpiece is processed, hole after processing is measured, calculate the accurately machined surplus of still needing, rotation single pole micrometer right-hand member knob, the distance that the micrometer left end is moved right equals to need accurately machined surplus 1/2 just, taking off knife bar 3 from the machining center main shaft packs in tapered sleeve 2, boring cutter is stretched out, point of a knife is contacted with the micrometer left end, boring cutter has just mixed up like this.
Can correspondingly adjust the position of guide pin bushing 6 on column 5 according to the height of knife bar.
