Description

Technical Field

[0001] The utility model relates to the field of detection, in particular to the technical field of coaxiality detection and trimming of left and right round rods of a screw nut seat, and specifically provides a screw nut seat assembly detection and trimming platform. Background Art

[0002] After the existing screw nut seat is assembled, it needs to be connected to the simulated mounting table with bolts, and the maximum outer diameters of the left and right outer walls of the round rod passing through the center of the screw nut seat are detected by a dial indicator to determine whether the bottom surface of the assembly center of the screw nut seat is flat. If the dial indicator detection readings of the round rods on both sides are out of tolerance, the technician needs to remove the screw nut seat from the simulated mounting table and clamp it on the bench vise, and then use a file to trim it before installing it on the simulated mounting table. If the amount of trimming required is not large, it is easy to trim too much with a file, and it is very troublesome to carry the parts back and forth for installation. Summary of the Invention
