Problems solved by technology

[0004] However, during the research and development and trial production of the spindle, there is usually no suitable machine tool to assist in the test of the spindle error; in this case, if there is no suitable device to adjust the positional relationship between the sensor and the test spindle, it will not only cause the test Low efficiency and difficult to guarantee test accuracy

Embodiment Construction

[0021] The invention will be further described below in conjunction with the accompanying drawings. The base 1 is the installation basis of the adjustment device. During the application process, the device is fixed to the test site through the base 1 . The base 1 is equipped with a guide sleeve 16, the guide sleeve 16 and the guide rod 17 fixed on the lifting plate 3 form a sliding pair, the axis of the sliding pair is perpendicular to the horizontal plane; handles 15 are fixed on both sides of the lifting plate 3; Driven by the drive, the height of the lifting plate 3 can be adjusted freely, and a group of “U” shaped spacers 25 with appropriate height can be inserted into the guide rod 17 to support the lifting plate 3 on the guide sleeve 16. One end of the compression screw 2 is fixed on the base 1, and the other end passes through the lifting plate 3, and the lifting plate is compressed by the nut 14. The quantity of compression screw rod 2 and nut 14 can be selected accord...

Abstract

The invention relates to a sensor position adjusting device for spindle rotation error detection. The sensor position adjusting device for the spindle rotation error detection is structurally characterized in that a guide sleeve is installed on a base, the guide sleeve and a guide rod fixed on a lifting plate form a sliding pair, an axis of the sliding pair is perpendicular to the horizontal plane, one end of a compression screw is fixed on the base, a thread is machined at the other end of the compression screw, the compression screw penetrates through the lifting plate and is equipped with a nut, a supporting plate is fixed on the lifting plate and attached to the plane of an installation plate, key grooves are formed in the supporting plate and the installation plate respectively, two sliding flat keys are fixedly combined together to form a crossed shape, and the two sliding flat keys are matched with the corresponding key grooves. A sensor support and a limiting block are installed on the installation plate, a detection stick is connected with a spindle to be measured, and a stepped shaft is arranged in a central hole in the end portion of the detection stick. The sensor position adjusting device can ensure that a laser displacement sensor which is used for measuring radial rotation errors of the spindle and the detection stick are in the correct relative positions through the adjustment of the device.

Description

technical field [0001] The invention relates to a mechanical adjustment device, specifically a device for adjusting the position of the sensor relative to the detection rod in the measurement of the rotation accuracy of the spindle, which can save the dependence on the test machine tool and can ensure good test efficiency and effect . Background technique [0002] Spindle rotation error is a key indicator to reflect the dynamic performance of the spindle, and it is also an important factor affecting the machining accuracy of the machine tool. Through the test of the spindle rotation error, the performance of the spindle can be evaluated, and the minimum shape error, surface quality and roughness that the machine tool can achieve under ideal processing conditions can be predicted; the cause of the processing error can also be traced back, and the error compensation of the machine tool can be performed Control to improve the machining accuracy; and can carry out condition mon...
