Device for detecting angle deviation of plane plate on web surface of T section quickly

Abstract

The invention discloses a rapid detection device for detecting the deviation of the angle between the T-shaped flat plate and the web surface. Above the positioning plate, there is a scale plate (10) which is fixedly connected by surrounding columns and is parallel to the back plate. Angle engraved on it; a semicircle protractor angle indicator plate (9) with a shaft hole formed on the central axis, which is movably connected to the fork lug shaft (6) of the bracket (2) through the semicircle hole slot , one end of the bracket is vertically fixed on the bottom plate, and one end is formed with a fork ear, and the protractor angle indicating plate on the same plane as the scale plate is rotatably connected to the outer plane of the bracket fork ear through a movable joint bearing (7), and rotates around the axis of the rotating shaft . The invention solves the problems of cumbersome detection operation, low efficiency and inaccurate detection results in the prior art.

Description

technical field [0001] The invention relates to a rapid detection device for detecting the angle value of a T profile. Background technique [0002] In a large number of T-shaped profiles in the machinery manufacturing industry, the upper plane of the T-shaped profile usually has a certain angle requirement for the web surface on the vertical plane. Since the angle deviation between the upper plane of the T-shaped bar and the web surface cannot be observed with the naked eye, it is difficult to use general measuring tools, the test results are unstable, and the test is labor-intensive and the efficiency is very low. In the prior art, the angle detection of the web surface of the T profile generally adopts a universal angle ruler and a series of transfer auxiliary devices for identification and detection. During the detection process, the positioning reference plane of the positioning side of the universal angle ruler is extremely small. Since the T-shaped web surface does ...

AI Technical Summary

Problems solved by technology

During the detection process, the positioning reference plane of the positioning side of the universal angle ruler is extremely small. Since the T-shaped web surface does not have a suitable positioning reference surface, an indirect transfer device is required for the contact of the T-shaped material web surface during detection. In addition, it is necessary to constantly adjust the positioning edge of the universal angle ruler and the detection position of the upper plane of the T profile. The measured angle value of the T profile is not necessarily accurate. The indirect operation is very cumbersome, the efficiency is very low, and the detection results are not accurate. Quality progress is difficult to grasp

If the number of T-shaped profiles to be detected is large, there are many varieties, and the shapes are similar, the detection workload and labor intensity are very large.
