Device and Method for Measuring Dimensions of Back Boring Cutter

摘要

The present invention provides a device and method for measuring dimensions of a back boring cutter. The device is formed by a measuring portion (1), a connecting portion (2) and a clamping portion (6). The measuring portion (1) has a first horizontal through hole (7), a horizontal hole (5) and a vertical hole (4). The clamping portion (6) comprises a second horizontal through hole (7′), a side wall of the second horizontal through hole (7′) is provided with a bolt hole (8), and a bolt (3) passes through the bolt hole (8) to install and fix a to-be-measured back boring cutter. One end of the connecting portion (2) is fixed on the measuring portion (1), while the other end is fixed on the clamping portion (6). The device and the method of the present invention have the advantages that simple measurement of important dimensions of the back boring cutter is realized, and dimension detection of the back boring cutter is simpler and more accurate.

主权项

1. A device for measuring dimensions of a back boring cutter, formed by a measuring portion (1), a connecting portion (2) and a clamping portion (6), and characterized in that: the measuring portion (1) has a first horizontal through hole (7) along a vertical direction of the device for measuring dimensions of a back boring cutter, a horizontal hole (5) perpendicular to the first horizontal through hole (7) and communicating with the first horizontal through hole (7), and a vertical hole (4) perpendicular to and identical with the first horizontal through hole (7) and the horizontal hole (5); the diameter of the first horizontal through hole (7) is set to be greater than the radial diameter of a back boring cutter; the clamping portion (6) comprises a second horizontal through hole (7′) which is set to be aligned with the first horizontal through hole (7); the diameter of the second horizontal through hole (7′) is set to be greater than the radial diameter of a back boring cutter; a side wall of the second horizontal through hole (7′) is provided with a bolt hole (8); a bolt (3) passes through the bolt hole (8) to install and fix a to-be-measured back boring cutter; and one end of the connecting portion (2) is fixed on the measuring portion (1), while the other end is fixed on the clamping portion (6).
