Abstract

The invention relates to a reverse boring cutter, and belongs to the technical field of a machining cutter. The reverse boring cutter comprises a cutter bar (1), a cutter body, a slide valve (2), a mandril (4), a blanking cap (5), a spring (6) and a hinge pin (8), wherein the tail part of the cutter bar is provided with a high through cooling fluid through hole (101), the middle part of the cutter bar is provided with a cavity (102) for holding the slide valve and a cavity (103) for holding the cutter body, and the head of the cutter bar is provided with a cavity (104) for holding the mandril, a spring and the blanking cap and a hole for installing the hinge pin (8); the slide valve is arranged in the cavity (102), and can slide axially along the cutter bar, the cutter body is installed in the cavity (103) through the hinge pin and can rotate freely by taking the hinge pin as a shaft in the cavity, the mandril sliding axially along the cutter bar and the spring fixedly connected with the cutter bar are arranged in the cavity (104). According to the reverse boring cutter provided by the invention, the problems that the reverse boring cutter is complicate in structure, high in manufacturing cost and low in durability, and cooling equipment needs to be installed additionally at work can be solved.

Description

technical field [0001] The invention relates to an anti-boring tool, which belongs to the technical field of machining tools. Background technique [0002] The machining of traditional reverse countersinking usually adopts the method that the tool bar passes through the machined through hole and manually loads the boring tool from the opposite direction. Factors such as cavity size make it impossible to manually load the tool. With the development of tool design technology, various forms of counterboring tools have appeared one after another, with the functions of forward feeding and automatic opening and closing of the tool holder, which continuously improves the processing ability of reverse countersinking and realizes high-efficiency machining. . For example, Invention 201010127220.2 discloses a reverse boring tool that utilizes the reverse and forward rotation of the tool holder to realize the recovery and opening of the tool body. However, on the one hand, the design...
