An improved ballbar device based on laser ranging, which also includes a magnetostatic ball, a laser ranging mechanism, a telescopic part, a reflecting part, a three-point measuring mechanism, and a distance between the magnetostatic ball and the three-point measuring mechanism One side of the magnetostatic ball is connected to the regulator, and the other side is adsorbed on the magnetic bowl seat; the side of the regulator away from the magnetostatic ball, the laser distance measuring mechanism, the telescopic part, reflection part and three-point measuring mechanism are connected in sequence; the three-point measuring mechanism is sleeved outside the high-precision ball of the machine tool under test, and the three-point measuring mechanism performs interpolation movement with the high-precision ball; one end of the reflecting part Embedded at the end of the telescopic part away from the laser ranging mechanism; the three-point measuring mechanism can drive the reflective part to perform interpolation movement along with the high-precision ball. The invention can measure the accuracy of the whole space range, and the accuracy of the measurement accuracy is high, and the accuracy of the measurement of the precision of the numerical control machine tool is improved.
Description
technical field [0001] The invention relates to the field of error detection of numerical control machine tools, in particular to an improved ballbar device based on laser ranging. Background technique [0002] The machine tool is the main machine in the machinery manufacturing industry, and its precision directly affects the level of the manufacturing industry. Relevant data show that more than 80% of the machine tools must be debugged on site before their performance can reach the technical indicators during installation, and after the machine tool has been used for a period of time, regular inspections are required to ensure the normal working status of the machine tool. The ballbar is an instrument that can quickly, conveniently and economically test the accuracy of CNC machine tools. The ballbar was proposed by James B.Bryan of the Lawrence Livermore National Laboratory (LLNL) in the United States in 1982 and has been widely used. Applied to the evaluation and diagnosi...
