TECHNICAL FIELD
[0001] The utility model relates to work piece detection technical field especially relates to a frock for detecting work piece center line deflection angle. BACKGROUND
[0002] The cross tie spring seat assembly includes a shell, the shell is a groove type, two opposite circular arc grooves are formed in the edge of the shell, a pin shaft is welded on the side of the shell, the axis of the pin shaft is perpendicular to the surface of the shell, that is, the axis of the pin shaft is perpendicular to the line connecting the center points of the two circular arc grooves.
[0003] When detecting whether the pin shaft is perpendicular to the line connecting the center points of the circular arc grooves, a test column with the same curvature as the circular arc groove and a level are needed. First, the test column is vertically placed on the base so that the two circular arc grooves of the shell embed the test column, thereby the workpiece is properly positioned, the line connecting the center points of the two circular arc grooves of the workpiece is perpendicular to the horizontal plane, and the side of the shell where the pin shaft is located is on the vertical plane. Then, glue is filled between the circular arc groove and the edge of the test column to fix the workpiece and the test column, simulating the installation process of the workpiece. Then, the level is placed on the side wall of the pin shaft and made parallel to the pin shaft. The reading on the level is the reading of the included angle formed by the axis of the pin shaft and the horizontal plane. When the degree is zero, it indicates that the axis of the pin shaft is perpendicular to the line connecting the center points of the two circular arc grooves, that is, the pin shaft is perpendicular to the side of the shell where it is located. However, when the workpiece is glued to the test column, one person needs to hold the test column and the workpiece to prevent them from separating, and the other person needs to use glue to stick them together. The labor utilization rate is relatively low, and the stability is not high when holding the test column and the workpiece with hands. During the gluing process, the test column and the workpiece may move relative to each other, resulting in errors in the cooperation between them. After gluing them together, the detection result will be wrong. CONTENT OF THE UTILITY MODEL
