Abstract
The utility model discloses a chip breaking device of superhard lathe tool, characteristics are including chip breaking piece and the blade press plate of fixed mounting on the handle of a knife, the chip breaking piece is located the up end of blade, the blade is fixed on the handle of a knife, be provided with on the chip breaking piece and need not to carry out the chip breaking piece fixing device that changes to original structure of lathe tool, chip breaking piece fixing device includes base and stud, be provided with first screw hole on the base, be provided with the second screw hole on the chip breaking piece, the screw thread opposite direction of first screw hole and second screw hole, stud's both ends correspond ground and first screw hole respectively, second screw hole looks spiro union, the up end of base is provided with the indent, blade press plate's front end stretches into in the indent and pushes down the base, the advantage is that this chip breaking device utilizes superhard lathe tool to be used for fixed blade's blade press plate to fix the up end at the blade with the chip breaking piece from what take, has both realized the chip breaking function of superhard lathe tool, need not again to change original structure of superhard lathe tool.
Description
Technical field
This utility model relates to the chip breaking device in turnery processing, particularly relates to the chip breaking device of a kind of superhard lathe tool.
Background technology
At present, conventional in machining superhard lathe tool has PCD and CBN etc..Chip owing to producing in working angles can bring serious problem to processing; as: affect cutting ability and service life, the defective work piece machined surface of cutter, cause frequent shutdown in the course of processing; affect production efficiency etc.; therefore, the solution of superhard lathe tool chip breaking problem is one of key technology of practical implementation.But owing to the material of superhard lathe tool is difficult to, the superhard lathe tool of current major part does not possess chip breaking function, also having the superhard lathe tool of minority to carry chip-breaker, but difficulty of processing is overall relatively big, processing cost is high；And the thickness of superhard lathe tool is little, superhard lathe tool carries out fluting processing, the intensity of blade can be affected.And current existing turning-tool chip breaker is required for first being modified original structure on lathe tool substantially, just can be arranged on lathe tool by chip breaking device, this is obviously also not suitable for superhard lathe tool；Additionally, its position adjustment function of current turning-tool chip breaker is the most limited.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chip breaking device without the original structure of superhard lathe tool is modified just can being mounted directly fixing superhard lathe tool.
nullThe technical scheme that the above-mentioned technical problem of this utility model solution is used is: the chip breaking device of a kind of superhard lathe tool，Including chip breaking block and the blade pressuring plate being fixedly mounted on handle of a knife，Described chip breaking block is positioned at the upper surface of blade，Described blade is fixed on described handle of a knife，The chip breaking block fixing device without the original structure of lathe tool is modified it is provided with on described chip breaking block，Described chip breaking block fixing device includes pedestal and studs，The first screwed hole it is provided with on described pedestal，It is provided with the second screwed hole on described chip breaking block，The first described screwed hole is contrary with the hand of spiral of the second described screwed hole，The two ends of described studs respectively correspondingly with the first described screwed hole、The second described screwed hole bolt，The upper surface of described pedestal is provided with indent，The front end of described blade pressuring plate is stretched in described indent and pushes down described pedestal，Described pedestal is made to be fixed on the upper surface of described blade.
Described indent is to the chute arranged before and after described blade, unclamp blade pressuring plate, can be according to the different machining condition of superhard lathe tool, chip breaking block is moved, unclamp studs, chip breaking block can be rotated, to regulate chip breaking block position on blade so that the chip breaking effect of chip breaking block reaches optimal.
The lower end of described studs has been wholely set cone-shaped ejecting block, and described cone-shaped ejecting block withstands on the upper surface of described blade so that chip breaking block fixing relatively reliable.
Being arranged with lock washer on described studs, described lock washer is between described pedestal and described chip breaking block.
The anti-angle of considering to be worth doing of chip-breaker formed by the filings-breaking surface of described chip breaking block and the upper surface of described blade is 45 °～80 °.
Compared with prior art, the upper surface that for fixing the blade pressuring plate of blade, chip breaking block is fixed on blade that the utility model has the advantages that this chip breaking device utilizes that superhard lathe tool carries, both the chip breaking function of superhard lathe tool had been achieved, again without the original structure of superhard lathe tool is modified, and it is reliable to location, the clamping of chip breaking block, dismount and easy to use, simple in construction, low cost；Additionally, this chip breaking device applies also on other lathe tool.

Fig. 2 is top view of the present utility model；
Fig. 3 is chip breaking principle schematic of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
nullAs shown in the figure，A kind of chip breaking device of superhard lathe tool，Including chip breaking block 1 and the blade pressuring plate 3 being fixedly mounted on handle of a knife 2，Chip breaking block 1 is positioned at the upper surface of blade 4，The anti-angle α that considers to be worth doing of chip-breaker formed by the upper surface of the filings-breaking surface of chip breaking block 1 and blade 4 is 60 °，Blade 4 is fixed on handle of a knife 2，The chip breaking block fixing device without the original structure of lathe tool is modified it is provided with on chip breaking block 1，Chip breaking block fixing device includes pedestal 5 and studs 6，The first screwed hole (not marking in figure) it is provided with on pedestal 7，The second screwed hole (not marking in figure) it is provided with on chip breaking block 1，The hand of spiral of the first screwed hole and the second screwed hole is contrary，The two ends of studs 6 respectively correspondingly with the first screwed hole、Second screwed hole bolt，Lock washer 61 it is arranged with on studs 6，Lock washer 61 is between pedestal 5 and chip breaking block 1，The lower end of studs 6 has been wholely set cone-shaped ejecting block 62，Cone-shaped ejecting block 62 withstands on the upper surface of blade 4，The upper surface of pedestal 5 is provided with before and after blade 4 to the chute 51 arranged，The front end of blade pressuring plate 3 is stretched in chute 51 and pushes down pedestal 5，Pedestal 5 is made to be fixed on the upper surface of blade 4.
In above-described embodiment, the anti-angle α that considers to be worth doing of chip-breaker formed by the upper surface of the filings-breaking surface of chip breaking block 1 and blade 4 can select in the range of 45 °～80 ° according to the actual cut situation of blade 4.
