Problems solved by technology

[0002] Thread detection is an important task after thread processing, and it is also an important basis for evaluating the quality of threads. The existing thread detection device needs workers or mechanical transmission to transport the threaded pipe to the corresponding detection position, and then Manually clamp the workpiece and use inspection tools to inspect the threaded pipe. The process requires a lot of manual labor and the inspection efficiency is low.

Abstract

The invention relates to an automatic external thread detection device and a detection method. For the existing thread detection device, a threaded pipe is conveyed to a corresponding detection position by a worker or a mechanical transmission mode, a workpiece is clamped manually, a detection tool is used for detecting the threaded pipe, and the detection efficiency is low. The device in the invention comprises a rear fixed plate (29), the rear fixed plate is respectively connected with three linear optical axes (26) through optical axis support seats (25), the linear optical axes penetrate through a movable connecting plate (27) and are connected with a fixed plate (23), the movable connecting plate is connected with a push air cylinder (30) through a bolt A (21), the push air cylinder is connected with the floating connector (32) through a mandrel (31) at the front end, the floating connector is fixed on the fixed plate, a locking air cylinder (24) is installed on the right side ofthe middle position of the fixed plate, the left side of the fixed plate is connected with a three-jaw fixing assembly (24), and the fixed plate is connected with a cubic frame (13) through a bolt B (22). The detection method in the invention is used for the automatic external thread detection device.

Description

Technical field: [0001] The invention relates to an automatic external thread detection device and a detection method. Background technique: [0002] Thread detection is an important work that needs to be done after thread processing, and it is also an important basis for evaluating the quality of the thread. The existing thread detection device requires workers or mechanical transmission to transport the threaded pipe to the corresponding detection position, and then Manually clamping the workpiece and inspecting the threaded pipe with inspection tools requires a lot of manual labor, and the inspection efficiency is low. Invention content: [0003] The purpose of the present invention is to provide an automatic external thread detection device and detection method. When the device senses the threaded pipe to be tested, it automatically stops the movement and fixes and clamps it, and uses a CCD camera to shoot the workpiece and transmit the photo to the upper position. Th...
