Abstract
The invention relates to an anti-loose and anti-drop tool which comprises a cutter bar and a blade, wherein a sinking part used for mounting the blade is arranged at one end of the cutter bar, a threaded blind hole is formed in the sinking part, two intercrossed limiting grooves are arranged on the bottom surface of the sinking part, the blade is fixedly arranged in the sinking part through a bolt, and limiting projections matched with the limiting grooves are arranged on the bottom surface of the blade. Further, the end parts of the two intercrossed limiting grooves do not touch the periphery of the sinking part. Further, the section of each limiting groove is square. By adopting the above scheme, the limiting projections of the blade and the limiting grooves of the cutter bar are mutually matched, when the tool shakes to loosen the bolt and the depart the blade from the cutter bar, the limiting grooves can prevent the blade from departing from the cutter bar on a certain degree, the limiting grooves and the limiting projections are arranged to relieve the shake on a certain degree, in order to effectively improve the connection stability of the blade and the cutter bar and prolong the service life of the tool.
Description
Technical field
The present invention relates to machine tool technical field, be specifically related to a kind of locking anticreep cutter.
Background technology
The mode that blade is bolted and knife bar are fixed together, to in the process of workpiece, also in the process namely contacted with each other at cutter and workpiece, cutter shakes, the connection between blade and knife bar is easily made to loosen, blade has the trend departing from knife bar, and the connection between blade and knife bar is unstable, also affects the positioning precision of point of a knife on blade simultaneously.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of locking anticreep cutter.
Realize technical scheme of the present invention as follows:
A kind of locking anticreep 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 bottom surface in sinking portion is provided with two crossing stopper slots, described blade is bolted and is arranged in sinking portion, and the bottom surface of blade is provided with the spacing preiection agreed with mutually with stopper slot.
Further, the end of described two crossing stopper slots does not contact with the periphery in sinking portion.
Further, the cross section of described stopper slot is square.
Have employed above-mentioned scheme, the spacing preiection of blade and the stopper slot of knife bar agree with mutually, when there are vibrations and make bolt looseness, blade for departing from knife bar in cutter, stopper slot can stop blade to depart from knife bar to a certain extent, stopper slot and being arranged on of spacing preiection can slow down vibrations to a certain extent, the stability connected between effective raising blade and knife bar, improves cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
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 stopper slot, and 6 is bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
See Fig. 1,2, a kind of locking anticreep 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 bottom surface in sinking portion is provided with two crossing stopper slots 5, and described blade is fixedly installed in sinking portion by bolt 6, and the bottom surface of blade is provided with the spacing preiection agreed with mutually with stopper slot.
Structure of the present invention is simple, and easy for installation, the spacing preiection of blade and the stopper slot of knife bar agree with mutually, are fixedly connected with by blade by bolt with knife bar.When there are vibrations and make bolt looseness, blade for departing from knife bar in cutter, it is spacing that stopper slot and spacing preiection carry out in horizontal direction to blade, prevent blade from departing from knife bar, stopper slot and being arranged on of spacing preiection can slow down vibrations to a certain extent, the stability connected between effective raising blade and knife bar, improves cutting-tool's used life.Horizontal direction described above is the direction of place, the bottom surface horizontal plane being parallel to sinking portion.
For improving stopper slot and spacing preiection further to blade restraining ability, the end of described two crossing stopper slots does not contact with the periphery in sinking portion, and the cross section of described stopper slot is square.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention 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 invention.
