Abstract
The invention discloses a cutter with an adjustable cutter bar length. The cutter with the adjustable cutter bar length is characterized by comprising a cutter handle, a positioning and adjusting bolt, a cutter bar, a blade and a pressing bolt, wherein a square slot is transversely arranged on the cutter handle; a screwed hole is arranged on an upper surface of the cutter handle; a rear end of the cutter bar is arranged in the square slot of the cutter handle; the blade is fixed on a front end of the cutter bar by the pressing bolt; the positioning and adjusting bolt is installed with the screwed hole on the cutter handle in a matched manner for fixing and pressing the cutter bar. According to the scheme of the invention, the cutter bar and the cutter handle are separate, and are fixed by the positioning and adjusting bolt; the cutter bar can be pulled out a proper distance when a long hole is machined, and can be inwards pushed to an adjusted proper position when a short hole is machined, so that not only can the long hole be machined, but also service life of the cutter can be prevented from being shortened due to a rebounding phenomenon when an extremely long cutter bar machines the short hole.
Description
Technical field
The present invention relates to a kind of cutter, refer in particular to the cutter that a kind of knife bar length can be adjusted the length of knife bar according to the degree of depth of machining hole, belong to the metal cutting tool technical field.
Background technology
Traditional tools, handle of a knife and knife bar are one, the cutter of deep hole processing regular meeting when the processing shallow bore hole occurs sending out the service life that plays phenomenon and reduce cutter, and the precision of processing work also can reduce.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: the cutter that has proposed a kind of knife bar adjustable in length.
Technical solution of the present invention is achieved in that a kind of cutter of knife bar adjustable in length, comprises handle of a knife, location adjusting bolt, knife bar, blade, housing screw; Said handle of a knife laterally has a square groove, has screwed hole on the upper surface; Said knife bar rear end places in the square groove of handle of a knife; Said blade is fixed on the front end of knife bar through housing screw; Said location is regulated bolt and is cooperated installation with screwed hole on the handle of a knife, is used for fixing and compresses knife bar.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The cutter of a kind of knife bar adjustable in length of the present invention separates knife bar and handle of a knife, regulates bolt through the location and fixes, and when the processing slotted hole, pulls out suitable distance to knife bar; When processing weak point hole, push in knife bar, adjust suitable position, can process slotted hole like this, also can when processing weak point hole, knife bar not occur and send out the service life that the bullet phenomenon reduces cutter because of knife bar is long.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of the knife bar of the cutter of a kind of knife bar adjustable in length of the present invention when elongating;
Accompanying drawing 2 is the stereogram of the knife bar of the cutter of a kind of knife bar adjustable in length of the present invention when shortening;
Accompanying drawing 3 is the side sectional view of the cutter of a kind of knife bar adjustable in length of the present invention;
Wherein: 1, handle of a knife; 2, bolt is regulated in the location; 3, knife bar; 4, blade; 5, housing screw; 6, groove; 7, screwed hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
The cutter of the of the present invention a kind of knife bar adjustable in length shown in accompanying drawing 1-3 comprises handle of a knife 1, location adjusting bolt 2, knife bar 3, blade 4, housing screw 5, screwed hole 6; Said handle of a knife 1 laterally has a square groove 6, has screwed hole 7 on the upper surface; Said knife bar 3 rear ends place in the square groove 6 of handle of a knife; Said blade 4 is fixed on the front end of knife bar 3 through housing screw 5; Said location is regulated bolt 2 and is cooperated installation with screwed hole 7 on the handle of a knife 1, is used for fixing and compresses knife bar 3; Can regulate the length that bolt 2 is regulated knife bar 3 through the location according to the degree of depth of machining hole like this.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The cutter of a kind of knife bar adjustable in length of the present invention separates knife bar and handle of a knife, regulates bolt through the location and fixes, and when the processing slotted hole, pulls out suitable distance to knife bar; When processing weak point hole, push in knife bar, adjust suitable position, can process slotted hole like this, also can when processing weak point hole, knife bar not occur and send out the service life that the bullet phenomenon reduces cutter because of knife bar is long.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
