[0089] Slide the sliding member 12 on the carrier 11 toward the measuring assembly 30 to adjust the positions of the first measuring member 31 and the positioning member 21 so that the fixing member 213 is close to the measuring assembly 30 ;

[0090] The toggle member 326 is rotated, causing the connecting member 325 and the stylus rod 323 to rotate until the stylus 324 is driven by the stylus rod 323 to rotate to the notch 2132a. At this time, the stylus rod 323 is rotated in a plane parallel to the stylus rod 323, so that the protrusion 324a rotates above the workpiece 200 and abuts the workpiece 200.

[0091] The pressing member 22 rotates, extending into the positioning slot 2111 and pressing against the workpiece 200. The first measuring member 31 senses the pressure. When the pressure is within a preset range, the second measuring member 32 measures whether the distance traveled by the workpiece 200 is within a preset range, thereby determining whether the workpiece 200 passes. If so, the workpiece 200 is mounted on the machine. If not, the workpiece 200 is adjusted and measurement continues.

[0092] The above-mentioned detection device 100 can effectively and quickly measure the compressive stroke and pressure of the workpiece 200, reduce the manpower for machine adjustment, and lower the manpower cost; and improve the machine's transfer time, higher production efficiency; eliminate product trial production, and reduce manufacturing costs.
