The invention relates to the technical field of measuring devices, in particular to a device for measuring the symmetry of a keyway on a high speed tool holder. The device comprises a fixed block, a movable block, a cavity, a slider, a connecting block, a fixed spiral, a through hole, an inner screw rod, a measuring button, a stopper, an outer screw rod, a measuring block, and a spring. The measuring device is simple and reasonable in structure. The steps of using the device comprises: placing the high speed tool holder that needs to be measured on the movable block; fixing the high speed toolholder through the fixed block by means of lifting the connecting block; making the keyway right below the through hole in the measurement process of the keyway; adjusting the measuring block to be on the same horizontal plane as the bottom surface of the fixed block; measuring the height of the button such that the distance between the measuring button and the stopper is a predicted value; pressing the measuring button to determine whether the keyway of the high speed tool holder meets the machining requirements, thereby greatly reducing the operation difficulty and the labor intensity of workers.
Description
technical field [0001] The invention relates to the technical field of measuring devices, in particular to a high-speed tool shank keyway symmetry measuring device. Background technique [0002] The tool holder is a tool, which is the connection between the mechanical spindle and the tool and other accessories. At present, the main standards are BT, SK, CAPTO, BBT, HSK and other spindle models. High-speed toolholders are toolholders for high-speed machining with extremely high rotational speed. Some high-speed toolholders have precision keyways, which require high keyway symmetry. If the symmetry of the keyway is not high, it will cause great centrifugal force. [0003] Therefore, it is necessary to measure the symmetry of the tool shank keyway after the tool shank is manufactured. At present, it is necessary to provide a platform, a V-shaped block, a keyway measuring block and a double-column dial gauge height gauge. Put the block on the platform, then put the high-speed ...
