Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of deflection instrument, concretely points to a kind of supporting device of detection equipment for deflection instrument. BACKGROUND

[0002] Deflection instrument is the equipment for measuring the radial runout error of shaft parts. The instrument uses two tips to position the shaft parts, and measures the radial runout error of the parts directly in the radial direction of the measured parts by rotating the measured parts. The traditional deflection instrument can only detect the radial runout of the measured parts, and cannot detect the axial runout of the measured parts at the same time. Additional equipment is needed for detection, which is very troublesome.

[0003] Therefore, a deflection instrument capable of detecting axial and radial runout at the same time is put into use, and a corresponding supporting device is used to adjust the installation position of the detection equipment left and right and up and down to adapt to the detection of measured parts of different sizes. The supporting device uses a lead screw assembly to adjust the position, and the lead screw assembly is mainly used to position the slide on the lead screw assembly by clamping with a clamp. In this way, the installation position of the detection equipment can be adjusted and fixed. However, the clamping tightness is affected by the deformation of the lead screw surface due to wear and tear caused by pure clamping with a clamp. In particular, the lead screw assembly for longitudinal adjustment is also affected by the gravity of the slide, so it is more likely to move downward due to reduced tightness, which affects the detection of axial runout.

[0004] Therefore, the purpose of the present utility model is to design a supporting device for detection equipment for deflection instrument that can fix the lead screw assembly by flexible compression of rubber parts, effectively avoiding the wear and tear caused by traditional rigid clamping, and further ensuring the detection accuracy of the measured parts.
