The content of the invention
It is the main error in machine tool motion for the above-mentioned thermal deformation errors of main shaft in the prior art, accounts for the 50%-70% of lathe whole error rate, eliminate these errors or reduce these errors, may be such that the machining accuracy of numerical control machining center is greatly improved.Further optimize the 26S Proteasome Structure and Function of existing analyzer, will further facilitate the problem of progress of the Digit Control Machine Tool in high accuracy manufacture field, the invention provides a kind of analytical equipment for machine tool chief axis dynamic error.
To solve the above problems, a kind of analytical equipment for machine tool chief axis dynamic error that the present invention is provided is by following technical essential come solve problem：A kind of analytical equipment for machine tool chief axis dynamic error, including shaft sleeve and the sensor being arranged on shaft sleeve, the sensor more than one, sensor is each attached on the side wall of shaft sleeve, and sensor is electric induction sensor, the measurement point of each sensor is not located along the same line.
Specifically, the shaft sleeve of setting is used to fix each sensor, when shaft sleeve is sheathed on main shaft, each sensor then forms the multiple noncontacting proximity sensors relative to tested main shaft, so, this structure conveniently can be installed on the main shaft of lathe, to complete the dynamic error and thermal deformation analysis of main shaft；Further, this sensor may be such that sensor is appointed in wet environment and so ensure that good certainty of measurement using the further restriction of electric induction sensor；The sensor mounting location that the measurement point of each sensor is not located along the same line is limited, it is intended to be easy to efficiently measure the inclination of main shaft, deflection, the error analysis on X-axis, Y-axis and Z axis etc..
Further technical scheme is：
For ease of needing to change sensor type or model according to specific measurement, magnetic bases are provided with the sensor, each sensor is adhered on shaft sleeve by the magnetic bases magnetic on respective.
To cause that this structure has main shaft rotation brake function, to enrich the operation strategies of this structure, such as can be used in the test analysis of the single main shaft for departing from, also including being fixed on the drive division of shaft sleeve either end.
For ease of the fixation of this structure, base is further fixed on the free end of the drive division.
To enable that this structure is conveniently accomplished the inclination of measurement main shaft, deflection, the error analysis on X-axis, Y-axis and Z axis, the quantity of the sensor is at least five.
The invention has the advantages that：
The shaft sleeve of setting is used to fix each sensor, when shaft sleeve is sheathed on main shaft, each sensor then forms the multiple noncontacting proximity sensors relative to tested main shaft, so, this structure conveniently can be installed on the main shaft of lathe, to complete the dynamic error and thermal deformation analysis of main shaft；Further, this sensor may be such that sensor is appointed in wet environment and so ensure that good certainty of measurement using the further restriction of electric induction sensor；The sensor mounting location that the measurement point of each sensor is not located along the same line is limited, it is intended to be easy to efficiently measure the inclination of main shaft, deflection, the error analysis on X-axis, Y-axis and Z axis etc..
