Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: the protrusion measuring instrument comprises an instrument base, an instrument frame and a measuring device. The measuring device comprises a measuring base 7, a pull rod 11, a measuring sleeve 6 and a measuring instrument 12. The measuring base 7 is slidably mounted on the instrument base body, the pull rod 11 is mounted in the measuring base 7, the lower end of the pull rod 11 extends into the instrument base body, and the upper end of the pull rod 11 extends out of the measuring base 7. The measuring sleeve 6 is arranged at the upper end of the pull rod 11, the lower end of the measuring sleeve 6 is in an annular shape and used for pressing an inner ring or an outer ring of the piece to be measured 13, the width and the position of the annular shape are consistent with those of the inner ring or the outer ring of the piece to be measured 13, the inner ring measuring sleeve is used when the inner ring is pressed, and the outer ring measuring sleeve is used when the outer ring is pressed. The measuring instrument 12 is mounted on the instrument base body through the instrument stand, and a probe of the measuring instrument 12 is in contact with the upper surface of the measuring sleeve 6.
When the device is used, in order to facilitate installation, the measuring base 7 slides out of the position right below the measuring instrument 12, the measuring sleeve 6 is detached, a bearing inner hole of a semi-finished bearing of the piece to be measured 13 is matched with the pull rod 11 and then placed on a platform of the measuring base 7, the inner ring measuring sleeve is installed, the pull rod 11 is matched with the inner ring measuring sleeve through a middle hole of the measuring base 7 to apply axial load to the inner ring of the bearing of the piece to be measured 13, and the numerical value on the measuring instrument 12 is read; and repeating the operation, replacing the inner ring measuring sleeve with the outer ring measuring sleeve to read the numerical value, wherein the difference value of the two numerical values is the protrusion amount of the inner ring relative to the outer ring. According to different types of bearings, the other matched sleeve (the other row of convex amount) is respectively measured, and the redundant size is ground off, so that the axial load applied by the bearing just eliminates the axial clearance in the matched use process. If the model needs to be replaced in the using process, the measuring base 7, the pull rod 11 and the measuring sleeve 6 can be replaced.
