Example Embodiment
[0017] Example 1:
[0018] like figure 1 As shown, a spindle deformation analysis device includes a shaft sleeve 4 and a sensor 3 arranged on the shaft sleeve 4. There are more than one sensor 3, and the sensors 3 are all fixed on the side wall surface of the shaft sleeve 4, and the sensor 3 are all electric induction sensors 3, the measurement points of each sensor 3 are not located on the same straight line, and an electric heating coil is also provided on the side wall of the shaft sleeve 4.
[0019] In this embodiment, the provided shaft sleeve 4 is used to fix each sensor 3. When the shaft sleeve 4 is sleeved on the main shaft, each sensor 3 forms a plurality of non-contact sensors 3 relative to the measured main shaft, so that , the structure can be easily installed on the main shaft of the lathe to complete the dynamic error and thermal deformation analysis of the main shaft; further, the sensor 3 is further limited by the electric induction sensor 3, which can make th...
Example Embodiment
[0020] Example 2:
[0021] This embodiment is further limited on the basis of Embodiment 1, such as figure 1 As shown in the figure, a further technical solution is: in order to facilitate the replacement of the type or model of the sensor 3 according to specific measurement needs, the sensor 3 is provided with a magnetic base 1, and each sensor 3 is magnetically attached to the magnetic base 1 through the respective magnetic base 1. on the shaft sleeve 4.
[0022] In order to make the structure have the function of spindle rotation braking, to enrich the application range of the structure, such as the test analysis of a single spindle that can be used for disengagement, it also includes the driving part 2 fixed to either end of the shaft sleeve 4 .
[0023] In order to facilitate the fixing of the structure, a base 1 is also fixed on the free end of the driving part 2 .
Example Embodiment
[0024] Example 3:
[0025] This embodiment is further limited on the basis of any one of the solutions provided in the above embodiments. In order to enable this structure to conveniently complete the measurement of the inclination and deflection of the main shaft, the error analysis on the X-axis, the Y-axis and the Z-axis is described. The number of sensors 3 is at least five.
