Abstract
The utility model relates to a kind of locking cutter, comprise knife bar and blade, one end of described knife bar is provided with the sinking portion of installing blade, sinking is provided with tapped blind hole in portion, the sidewall in sinking portion is provided with the spacing preiection parallel with the bottom surface in sinking portion, described blade is bolted and arranges in sinking portion, is provided with the side of the blade of the sidewall contact in sinking portion the stopper slot agreed with mutually with spacing preiection.Further, described spacing preiection is across the whole sidewall in sinking portion.Have employed above-mentioned scheme, the stopper slot of blade and the spacing preiection of knife bar agree with mutually, when there are vibrations in cutter, damping, buffering is carried out by stopper slot and spacing preiection, reduce vibrations to the impact connected between blade and knife bar, thus improve the stability connected between blade and knife bar, improve cutting-tool's used life.
Description
Technical field
The utility model relates to machine tool technical field, is specifically related to a kind of locking cutter.
Background technology
The mode that blade is bolted and knife bar are fixed together, to in the process of workpiece, in the process also namely contacted with each other at cutter and workpiece, cutter shakes, easily make the connection between blade and knife bar loosen, also affect the positioning precision of point of a knife on blade simultaneously.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of locking cutter.
Realize the technical solution of the utility model as follows:
A kind of locking cutter, comprise knife bar and blade, one end of described knife bar is provided with the sinking portion of installing blade, sinking is provided with tapped blind hole in portion, the sidewall in sinking portion is provided with the spacing preiection parallel with the bottom surface in sinking portion, described blade is bolted and arranges in sinking portion, is provided with the side of the blade of the sidewall contact in sinking portion the stopper slot agreed with mutually with spacing preiection.
Further, described spacing preiection is across the whole sidewall in sinking portion.
Have employed above-mentioned scheme, the stopper slot of blade and the spacing preiection of knife bar agree with mutually, when there are vibrations in cutter, damping, buffering is carried out by stopper slot and spacing preiection, reduce vibrations to the impact connected between blade and knife bar, thus improve the stability connected between blade and knife bar, improve cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 exploded view;
In figure, 1 is knife bar, and 2 is blade, and 3 is sinking portion, and 4 is tapped blind hole, and 5 is spacing preiection, and 6 is bolt, and 7 is stopper slot.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1,2, a kind of locking cutter, comprise knife bar 1 and blade 2, one end of described knife bar is provided with the sinking portion 3 of installing blade, tapped blind hole 4 is provided with in sinking portion, the sidewall in sinking portion is provided with the spacing preiection 5 parallel with the bottom surface in sinking portion, and described blade is fixedly installed in sinking portion by bolt 6, is provided with the side of the blade of the sidewall contact in sinking portion the stopper slot 7 agreed with mutually with spacing preiection.
The utility model structure is simple, and easy for installation, the stopper slot of blade and the spacing preiection of knife bar agree with mutually, are fixedly connected with by blade by bolt with knife bar.Stopper slot and spacing preiection carry out the location on vertical direction to blade, and bolt carries out the location on level and vertical direction to blade, improve the stability connected between blade and knife bar.When there are vibrations in cutter, carry out damping, buffering by stopper slot and spacing preiection, reduce vibrations to the impact connected between blade and knife bar, reduce the possibility of bolt looseness, thus improve the stability connected between blade and knife bar, improve cutting-tool's used life.In addition, the utility model also can improve the positioning precision of point of a knife.Horizontal direction described above is the direction of place, the bottom surface horizontal plane being parallel to sinking portion.
During cutter vibrations, spacing preiection and stopper slot stressed, namely for making uniform force on spacing preiection, also damping is even, and described spacing preiection is across the whole sidewall in sinking portion, and so design can improve cutting-tool's used life.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
