In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of composite hard alloy brazed shank tool, be intended to solve existing cutter complex procedures when processing automobile part rear braking cam supporting bore, locate easy deviation, the problem such as of low quality of institute's machining hole.
The technical solution of the utility model is as follows:
A kind of composite hard alloy brazed shank tool, comprise connection handle, ream cutter hub and expand sharpener body, described connection handle is connected by transfer neck one end with ream cutter hub, the other end of ream cutter hub is connected with expansion sharpener body, one end in reamer surface away from connection handle is provided with ream cutter head, the surface expanding sharpener body is provided with the first expansion sharpener head and second and expands sharpener head.
Preferably, axially gib block is provided with on the surface of ream cutter hub along it.
Preferably, described ream cutter head, first expands sharpener head and second and expands sharpener head and be all made up of carbide alloy, and ream cutter head is welded on ream cutter hub, and the first expansion sharpener head and second expands sharpener head and is welded on and expands on sharpener body.
Preferably, described gib block is connected with ream cutter head head and the tail, and described first expansion sharpener head and second expands sharpener head head and the tail and is connected.
Preferably, be provided with arch brace between described gib block and ream cutter head, described first expands sharpener head and second expands between sharpener head and is provided with bar shaped contiguous block.
Preferably, the cross section of described ream cutter head is ratchet-like.
Preferably, the described first cross section expanding sharpener head is made up of a cylindrical cross-section and a ring surface, and cylindrical cross-section is arranged on inner ring one end of ring surface, and the described second cross sectional shape expanding sharpener head expands sharpener head with first.
Beneficial effect:
(1) the processed hole of part can be expanded sharpener head and once be machined on an equipment by the ream cutter head in the utility model, the first expansion sharpener head and second, being concentrated by 3 operations of original dispersion is 1 operation, save equipment, avoid the machining deviation repeating to process, resetting causes, machining accuracy is high.
(2) set up gib block on the surface of ream cutter hub, be conducive to improving positioning precision.
(3) ream cutter head, the first expansion sharpener head and second expand sharpener head and are all made up of carbide alloy, and be welded on ream cutter hub respectively and expand on sharpener body, add and can improve working (machining) efficiency man-hour, tool life also increases.
(4) shape that sharpener head and second expands sharpener head is expanded to ream cutter head, first and carry out particular design, be convenient to the crudy in raising hole.
In sum, the utility model can make the processing technology of hole in piece part be optimized lifting, saves equipment, and avoid the machining deviation repeating to process, resetting causes, machining accuracy is high.
