As shown in fig. 1 to 8, the present application provides a height difference measuring device 1 including a knob 11, a dial 12, a support bar 14, a depth probe 15, and a positioning bracket 13. The supporting rod 14 is fixedly arranged below the dial 12, the depth probe 15 is telescopically arranged on the supporting rod 14, and the supporting rod 14 is fixedly connected with the positioning support 13. The dial 12 is used to display the amount of expansion and contraction of the depth probe 15, and the connection elements and connection relationship between the depth probe 15 and the dial 12 are not particularly limited in this application. The knob 11 is provided on the dial 12 for adjusting the amount of expansion and contraction of the depth probe 15. When the measuring device 1 is not measuring, the zero setting can be carried out by the adjusting knob 11, so that the bottom end of the positioning bracket 13 and the bottom end of the depth probe 15 are in the same plane.

Further, the positioning bracket 13 includes at least three supporting legs 131, the supporting legs 131 are disposed at an interval to each other outside the supporting bar 14, and the supporting legs 131 are L-shaped and extend downward, and bottom ends of the supporting legs 131 are on the same plane to collectively determine the reference plane.

Further, the support rod 14 has an accommodating cavity 141 extending up and down for accommodating the depth probe 15 therein, and the shape of the lower surface of the depth probe 15 is not particularly limited in the present application.

The measuring device 1 can be used in particular for measuring the height difference of a rubber suction cup 2 workpiece. The rubber sucker 2 comprises a base plate 21, a rubber pad 22 and a sucker hole 23, wherein the sucker hole 23 is arranged in the center of the base plate 21 and extends upwards, and the rubber pad 22 is arranged on the base plate 21 in a circular ring shape. The lower surface of the suction cup hole 23 is a first plane 231, the upper surface of the base plate 21 is a second plane 211, and the measuring device 1 can measure the height difference a between the first plane 231 and the second plane 211.

Further, the rubber pad 22 has a certain elasticity, so that the fitting of the rubber pad 22 and the positioning bracket 13 can be made tighter at the time of measurement.
