Abstract
The utility model provides an end surface tooth combined broach, which comprises an end surface tooth broach and a chamfer broach, wherein the end surface tooth broach and the chamfer broach are free of tool handles; the end face tooth broach and the chamfering broach without the tool shank are sequentially fixed on the mounting surface of the tool holder through screws, and the front end of the tool holder is provided with a plug pin hole which can be matched with a chuck of a broaching machine. The combined broach with the structure adopts the structure that the tool holder is separated from the tool, the tool holder can be made of common carbon steel, the broach has no tool shank, shortens by 40% compared with the original tool shank, saves a large amount of high-speed steel materials, easily guarantees the manufacturing precision of the broach and facilitates sharpening. On the other hand, one tool holder can be matched with different broaching tools for use, so that the aim of multiple purposes of the tool holder is fulfilled.
Description
Technical field
The utility model relates to horizontal broaching machine end face tooth built-up broach.
Background technology
At present, the end face tooth of broaching bead and flange york on horizontal broaching machine all adopts the solid broach of belt length handle, and pin hole is arranged on handle of a knife, and broach length reaches about 1.5 meters, broaching tool manufacturing expense height, and cost of goods manufactured height.
Summary of the invention
The utility model is at the high deficiency of manufacturing expense of existing horizontal broaching machine upper surface tooth broaching tool, and cancellation broaching tool handle of a knife provides a kind of easier, reliable and stable horizontal broaching machine end face tooth built-up broach.
For this reason, the technical solution of the utility model is as follows: end face tooth built-up broach, comprise end face tooth broaching tool, chamfering broaching tool, and it is characterized in that: described end face tooth broaching tool, chamfering broaching tool are no handle of a knifes; It also has a cutter holder, and end face tooth broaching tool, the chamfering broaching tool of no handle of a knife are fixed on the installed surface of cutter holder by screw successively, and the front end of cutter holder is provided with the pin hole that can cooperate with the broaching machine dop.
The built-up broach of this structure adopts cutter holder and cutter separated structures, and cutter holder can be used the common straightcarbon steel manufacturing, and broaching tool does not have handle of a knife, than original shortening 40%, has saved a large amount of high speed steel materials, guarantees the accuracy of manufacture of broaching tool easily, and makes things convenient for sharpening.On the other hand, on the cutter holder can with the supporting use of different broaching cutters, reach the purpose that a cutter holder is used more.
