As a preferred embodiment of the reamer head, an end face screw hole is formed in the end face of the thread section of the reamer head, a center hole is formed in the axis of the reamer handle, and a screw rod of the bolt penetrates through the center hole of the reamer handle to be in threaded connection with the end face screw hole of the reamer head.
As a preferred embodiment of the present utility model, the thread direction of the thread section of the reamer head is opposite to the rotation direction of the reamer.
In a preferred embodiment of the present utility model, the taper angles of the frustum and the taper hole are 120 °.
After the structure is adopted, the utility model has the following beneficial effects:
the reamer handle and the reamer head are of a split structure, a threaded section is arranged at the rear end of the reamer head, a frustum is arranged at the bottom of the threaded section, a screw hole is formed in the front end of the reamer handle, a taper hole is formed in the top of the screw hole, the threaded section of the reamer head is in threaded connection with the screw hole of the reamer handle, and the frustum at the bottom of the threaded section is arranged in the taper hole in the top of the screw hole. When the reamer is in work, the reamer handle can be reused, when part of cutter teeth in the reamer head are damaged, the reamer head does not need to be replaced integrally, and semi-finishing and finishing procedures in the reamer machining process can be realized only by replacing the reamer head, so that the production cost is greatly reduced; moreover, when holes with different sizes and specifications are required to be machined, only different reamer heads corresponding to the holes are required to be replaced, so that the machining time is shortened, and the production efficiency is improved.
According to the reamer head, the end face screw hole is formed in the end face of the thread section of the reamer head, the center hole is formed in the axis of the reamer handle, the screw rod of the bolt penetrates through the center hole of the reamer handle to be in threaded connection with the end face screw hole of the reamer head, and the tightness and reliability of connection between the reamer head and the reamer handle can be improved through the bolt.
The thread direction of the thread section of the reamer head is opposite to the rotation direction of the reamer, so that the reamer rotates more tightly the reamer head is connected with the reamer handle in the using process of the reamer, and the reamer head is effectively prevented from being loosened in the processing process.
The taper angles of the frustum and the taper hole are 120 degrees, so that the contact area between the reamer handle and the reamer head is large, and the reamer head and the reamer handle are connected more stably.
The utility model has simple structure and is convenient for popularization and application.
