Pneumatic measuring device for detecting edge processing quality of spool of slide valve

Abstract

The invention relates to the technical field of slide valve core detection devices, and discloses a pneumatic measuring device for slide valve core edge processing quality detection, the pneumatic measuring device comprises a head clamp cover and a displacement mechanism, the interior of the head clamp cover is fixedly connected with a mounting plate, and the outer side of the mounting plate is rotatably connected with a driving lever disc; a center is fixedly connected to the outer side of the shifting rod disc, an electric sliding rail is installed at the bottom of the head clamp cover, a sliding seat is installed on a moving seat of the electric sliding rail, a position top is fixedly connected to the top of the sliding seat, a top head is installed in the position top, and a valve element is arranged between the center and the top head. A main shaft is arranged at one end of the valve element, and the outer side of the main shaft makes contact with one end of a tip. Through cooperation of the ejector head with the spring and the tip, damage to the valve element during clamping is effectively avoided, the integrity of the valve element is ensured, the measuring mode is unique, a throttling opening is formed by a narrow slit in the surface of the measuring head and the edge of the valve element, and edge machining quality information can be accurately obtained.
