Description
Technical field
The utility model relates to a kind of benchmark blade cutting edge corner cutting off apparatus of doing for oneself.
Background technology
Impact resistance when superhard material blade (as ceramic tip, cubic boron nitride blade) cuts in order to strengthen cutting edge will carry out chamfered edge (being sharpening) at the cutting edge place.Because of size, the angle of cutting edge closely related with different machining conditions, so the required precision of cutting edge is higher behind the chamfered edge.
Understand according to the applicant, still do not have special-purpose blade cutting edge chamfering device now.So the chamfered edge of blade cutting edge can only adopt free-hand sharpening processing mode, transition relies on operating personnel's sharpening experience, and this makes that the required precision of cutting edge is difficult to up to standard behind the chamfered edge.
The utility model content
The technical problems to be solved in the utility model provides a kind of benchmark blade cutting edge corner cutting off apparatus of doing for oneself, and adopts this corner cutting off apparatus, can make behind the chamfered edge precision of cutting edge higher.
For solving the problems of the technologies described above, the utility model provides a kind of benchmark blade cutting edge corner cutting off apparatus of doing for oneself, it comprises knife bar, support chip, pad, there is first extension board width both sides of knife bar one end, second extension board, length direction first extension board along knife bar exceeds second extension board, one segment distance, one end of support chip and the exposed junction of first extension board join, pad is stacked on the end face of second extension board by the securing member level, the end face of pad is an inclined-plane that has a down dip near that side of support chip, the length of support chip makes its other end surpass first extension board and extends to the pad place, that side near pad on the support chip is a vertical plane, the height of support chip makes its downside be higher than the lower side on described inclined-plane, form between support chip and the pad and settle the cardinal principle V-arrangement of blade recessed, and the recessed lower end of V-arrangement forms the strip slit of exposing for blade cutting edge.
For can concise description for the purpose of the problem, below the benchmark blade cutting edge corner cutting off apparatus of doing for oneself described in the utility model be all abbreviated as this corner cutting off apparatus.
The other end of knife bar is located clamping on the two-way of knife sharpener or three-dimensional vice.During use, that side near pad on the rake face of blade and the support chip is reclined, the back knife face of blade and the bottom incline on the pad is reclined, like this, blade just be placed in V-arrangement recessed in, and blade cutting edge exposes from the strip slit of the recessed lower end of V-arrangement.Allow the emery wheel of knife sharpener near blade cutting edge, start knife sharpener, and with hand light push type broach sheet downwards, the rotation blade cutting edge by emery wheel carries out sharpening, thus with the rake face of blade itself and after knife face be benchmark, finish the chamfered edge of cutting edge.As seen, this corner cutting off apparatus becomes a kind of blade cutting edge chamfering device of special use.
Adopt this corner cutting off apparatus, can avoid adopting free-hand sharpening processing mode, no longer transition relies on operating personnel's sharpening experience, thereby makes that the precision of cutting edge is higher behind the chamfered edge.
In addition, simple and reasonable, the reliable advantage of handling safety that this corner cutting off apparatus also has.
Angle between described inclined-plane and the horizontal plane is 1～45 degree.Like this, can be according to the size of blade cutting edge and angle different, select suitable pad for use, to satisfy the needs of settling blade before the sharpening.
One end of described support chip and the exposed junction of first extension board join by securing member.Like this, be convenient to change support chip.
Described knife bar is a square bar, and the length of support chip is identical with the width of knife bar, and the length of pad is identical with the width of second extension board, and is mutually concordant with pad along the other end of the width support chip of knife bar.

Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a user mode schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is specifically described:
Referring to Fig. 1, Fig. 2: this corner cutting off apparatus comprises knife bar 1, support chip 2, pad 3, there is first extension board 11 the width both sides of knife bar 1 one ends, second extension board 12, length direction first extension board 11 along knife bar 1 exceeds second extension board, 12 1 segment distances, one end of support chip 2 and the exposed junction of first extension board 11 join by trip bolt 4, pad 3 is stacked on the end face of second extension board 12 by trip bolt 5 levels, the end face of pad 3 is an inclined-plane that has a down dip 31 near that side of support chip 2, angle between inclined-plane 31 and the horizontal plane is 31 degree, the length of support chip 2 makes its other end surpass first extension board 11 and extends to pad 3 places, that side near pad 3 on the support chip 2 is a vertical plane, the height of support chip 2 makes its downside be higher than the lower side on described inclined-plane 31, form to settle the cardinal principle V-arrangement of blade recessed 6 between support chip 2 and the pad 3, and the lower end of V-arrangement recessed 6 form for the exposed strip slit 61 of blade cutting edge.
The length ratio of first extension board 11 and second extension board 12 is 1.17: 1, and the ratio of the width of first extension board 11 and second extension board 12 is 1: 2.49.Knife bar 1 is a square bar, and the length of support chip 2 is identical with the width of knife bar 1, and the length of pad 3 is identical with the width of second extension board 12, and is mutually concordant with pad 3 along the other end of the width support chip 2 of knife bar 1.
