Abstract

This utility model discloses a nut detection device with positioning function to prevent leaks in the weld. It includes a clamping cylinder, a clamping arm, a first connecting member, a second connecting member, and a three-way positioning mechanism. The clamping arm is fixed to the output end of the clamping cylinder. The clamping arm, the first connecting member, and the second connecting member are connected sequentially from top to bottom. The three-way positioning mechanism is located on the first and second connecting members to position the workpiece in the X, Y, and Z directions. A clamping detection mechanism with a guide post is provided at the end of the second connecting member away from the first connecting member. The clamping cylinder has a built-in magnetic switch for detecting the position of the piston and providing a first clamping signal. The clamping detection mechanism has a proximity switch for detecting the position of the guide post and providing a second clamping signal. This device can simultaneously achieve positioning and prevent leaks in the weld, thus preventing nuts from being installed incorrectly.
