Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the deflection instrument, and specifically refers to an automatic detection device for deflection instrument. BACKGROUND

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

[0003] Therefore, the deflection instrument capable of detecting the axial and radial runout at the same time is put into use, and the corresponding translation mechanism and longitudinal movement mechanism are used for moving the probe to detect the axial and radial runout. The translation mechanism and longitudinal movement mechanism are both slide rail and groove structures. The slide block is only supported by the bolt on the slide rail of the longitudinal movement mechanism, and the bolt is longitudinally installed. The repeated upward movement and resetting of the slide block will impact the bolt, which will cause the bolt to loosen and affect the detection of the axial runout.

[0004] Therefore, the purpose of the present utility model is to design an automatic detection device for deflection instrument which can ensure normal installation of the longitudinal movement mechanism, provide strong support, effectively prevent the loosening and falling of the limiting bolt, and ensure the detection accuracy.
