Abstract

The invention discloses a centering broaching device which comprises a device shell. The device shell is internally provided with a first supporting base used for supporting a transmission shaft and a second supporting base used for supporting a motor which is controlled through a power supply switch on the device shell. A driven gear on the transmission shaft is engaged with a main gear on a motor spindle. A circle of transmission connecting rods are in hinge connection with the front end of the transmission shaft and are divided into two groups which are separately in hinge connection with two symmetrical tool fixing blocks. Two semicircular broaching tools are symmetrically arranged at the front ends of the two tool fixing blocks. By adoption of the centering broaching device, centering and positioning can be achieved in the broaching process, it is ensured that a broached hole is concentric with an original hole and is a regular circular hole, the hole pattern is attractive, the broaching size can be set, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to a centering hole reamer, which belongs to the technical field of mechanical processing. Background technique [0002] The existing hole reamer cannot locate the center of the original hole when reaming the processed hole, resulting in the second reamed hole not concentric with the original hole, irregular in shape, indeterminate in size, and the surface of the inner hole Problems such as unevenness will lead to misalignment of parts during assembly. At the same time, irregular holes will affect the practicability and aesthetics of the product and even produce waste products, which not only wastes manpower and parts, but also increases production costs virtually. Contents of the invention [0003] The purpose of the present invention is to provide a centering hole reamer to solve the problems of irregular shape, variable size, and uneven surface of the inner hole during secondary reaming, thereby improving the work efficiency ...
