Description
Technical Field
The utility model relates to a composite cutter for processing an axial hole of a camshaft, in particular to a composite cutter for processing a center hole, a counter bore and a threaded bottom hole of the end face of the camshaft.
Background
At present, the processing of a counter bore and a threaded bottom hole of a camshaft needs to be clamped twice, the threaded bottom hole is processed for the first time, the reaming is carried out for the second time, two different drill bits need to be replaced at the same time, the work is complicated, and the processing time is long; in addition, errors are accumulated in the two clamping processes, so that the coaxiality of the threaded bottom hole is difficult to guarantee, and the subsequent coaxiality of the threads is also difficult to guarantee.
Disclosure of Invention
The utility model aims to provide a composite cutter for machining axial holes of a camshaft, which can complete a plurality of procedures of drilling, reaming and central hole finishing in the process of one-time machining and has the characteristics of high efficiency, high precision and high reliability.
In order to achieve the purpose, the composite cutter for machining the axial hole of the camshaft comprises a cutter rod, wherein one end of the cutter rod is arranged as a cutter handle, a central hole trimming area is arranged below the cutter handle, a hole expanding area is arranged below the central hole trimming area, a drilling area is arranged below the hole expanding area, a water outlet hole is arranged in the central area of the end face of the cutter rod, the drilling area, the hole expanding area and the central hole trimming area are respectively provided with a spiral cutting edge, the diameter of the drilling area is smaller than that of the hole expanding area, and the diameter of the hole expanding area is smaller than that of the central hole trimming area.
The cutter bar is connected with the machine tool through the cutter handle, two water outlet holes are formed in the center of the end face of the cutter bar, and the drilling area, the reaming area and the central hole trimming area are combined in a trapezoidal mode to form the combined cutter.
The center of the end surface of the cutter bar is provided with two water outlet holes.
Compared with the prior art, the composite cutter for processing the axial hole of the camshaft has the following excellent effects.
According to the composite cutter for machining the axial hole of the camshaft, the axial hole machining composite cutter can shorten the auxiliary time of tool changing and feeding, and can reduce the varieties and the number of machine tools, clamps and cutters in machining; the machining size is ensured by the composite cutter, the machining of all sizes can be completed by one-time feeding, the size ensuring capability is greatly improved, in addition, the machining of the central hole and the thread bottom hole is completed in one-time clamping, and the subsequent thread coaxiality is favorably ensured.
The composite cutter is made of hard alloy, the composite cutter consists of a drilling area, an expanding area, a central hole trimming area and a water outlet hole, the water outlet hole is formed in the middle of the cutter, and cooling liquid of the composite cutter directly reaches the processing surfaces of the cutter and a workpiece through the water outlet hole to play a cooling role in working, so that the service life of the cutter is prolonged; in addition, the cooling liquid can be used for flushing out scrap iron generated during the working of the composite cutter, so that the composite cutter is prevented from being broken due to the accumulation of the scrap iron.
