Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

A multi-degree-of-freedom component height detection device as described in FIGS. 1 to 4 includes a base plate 1 , a base 2 , a first scale 3 , a connecting rod 4 and a second scale 5 .

The bottom plate 1 is provided with guide rails 14 and a protruding reference plane 6 . The guide rail is arranged on one side of the reference plane 6, and the reference plane 6 is used for placing the workpiece to be inspected. The base 2 is slidably connected to the guide rail 14 to facilitate the measurement of multiple detection points of the workpiece to be detected. The base 2 is provided with a fixing cylinder 7 extending upward, and the first scale 3 is slidably connected to the fixing cylinder 7 . The lower end of the base 2 is slidably connected to the guide rail 14, and the base 2 is provided with a third top wire 15, which can be connected with the upper surface of the bottom plate 1 by pressing, and thus the base 2 is fixed. on base plate 1. The first scale 3 is provided with several fixing holes 8 along the vertical direction, the fixing cylinder 7 is connected with a first top wire 9 , and the first top wire 9 can be connected with any one of the fixing holes 8 . The scale lines on the first scale 3 correspond to the fixing holes one by one. The scale on the first scale 3 close to the top surface of the fixed cylinder 7 is the size A described in FIG. 4 .
