Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1-3, a displacement measuring device comprises a cylinder 1, an ear plate cover 2, a spring 3, a roller 4, a support frame 5 and a sensor 6, wherein the cylinder 1 is hollow, the ear plate cover 2 seals the upper opening of the cylinder 1, the ear plate cover 2 is provided with a connecting ear plate I21, and the ear plate I21 is provided with an ear hole. One end of the support frame 5 is provided with a slide block 51, the slide block 51 is in clearance fit with the inner side of the cylinder body, the slide block 51 is positioned in the cylinder body 1 and can move up and down in the cylinder body 1, and the movement direction of the slide block is carried out along the central axis of the cylinder body. A spring 3 is provided between the slider 51 and the ear plate cover 2 in the cylinder 1. The other end of the support frame 5 is provided with a through cutting groove, the two sides of the cutting groove are provided with roller wheel brackets 52, each roller wheel bracket 52 is provided with a bearing hole, a bearing is placed in the bearing hole, the rotating shaft 41 in the middle of the roller wheel 4 is tightly matched with the bearing, and the roller wheel 4 is partially positioned in the cutting groove. The sensor 6 is mounted on the outside of the rotating shaft 41. The sensor 6 in this embodiment is shaft mounted and contains an encoder. The roller 4 is a rubber roller. The spring 3 is selected to have elasticity according to its actual condition.
As shown in fig. 3, end caps 7 are provided at two axial ends of the rotating shaft 41, the end caps 7 are fixed on the roller bracket 52, and the sensor 6 passes through one of the end caps 7 and is fixedly connected with one end of the rotating shaft 41.
