This utility model relates to a switch machine friction force testing device, including a base, two sets of sliding sleeves installed at both ends of the base, the sliding sleeves being used for positioning and installation on both sides of the switch machine, a main control box fixed to the top of the base, a connecting rod coaxially arranged with the main control box, and push rod grippers located below the ends of the connecting rods, the push rod grippers being arranged in two sets, the two sets of push rod grippers engaging the switch machine push rod in a circumferential manner, a steering rod passing through the center of the main control box, a rocking disk sleeved at one end of the steering rod, and an adapter ring for testing the friction of the switch machine shaft located below the rocking disk. By designing an integrated rigid base and a double-sided sliding sleeve structure, a stable and reliable installation benchmark is provided for the entire testing device, fundamentally eliminating the problem of force direction deviation caused by the shaking of the loading unit itself in traditional split devices. The adoption of a gripper-type built-in sensing structure and direct transmission with the steering rod greatly shortens the force transmission path and effectively avoids signal attenuation and distortion.
