Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic flange inspection, in particular to a glass fiber reinforced plastic flange hole position measuring device. Background Art

[0002] Flange is the most widely used detachable connection part in pipes and containers. Flange is just a general term, usually refers to a disk-like metal body with several holes for fixing around it for connecting other things. Flange is widely used in machinery. There are holes on the flange for bolts to make the two flanges closely connected, and the flanges are sealed with gaskets. With the increasing use of FRP pipes and containers, the performance and production of FRP flanges are gradually gaining widespread attention.

[0003] After the FRP flange is manufactured, the vacancies on the flange must be checked to prevent the holes from being misaligned when the bolts are inserted. Currently, the hole positions of the flange are usually measured manually using a caliper to measure the diameter and hole spacing of the holes. Manual measurement is not only time-consuming, but also has large errors and is not conducive to data collection of the hole positions. In this regard, we propose a FRP flange hole position measuring device. Utility Model Content

[0004] The purpose of the utility model is to provide a glass fiber reinforced plastic flange hole position measuring device to solve the above-mentioned shortcomings.

The two ends of the paired connecting rods are rotatably mounted on the clamping seat and the sliding seat respectively. The base is also provided with a guide groove and is located between the limit grooves. The slide is slidably mounted in the guide groove. Racks are fixedly mounted on both sides of the slide. The paired gears are rotatably mounted on the base and are located on both sides of the slide. The gears are meshed with the racks on the slide. A positioning hole is provided at the bottom of the front end of the slide. The measuring needle is fixedly mounted in the positioning hole. The pull rod is fixedly mounted on the upper end surface of the slide.

[0007] Preferably, the threads at both ends of the screw rod have opposite rotation directions.

[0008] Preferably, the measuring needle is cylindrical.

[0009] Preferably, a scale line is provided on one side of the guide groove on the base.

[0010] The beneficial effects that can be achieved by the utility model using the above technical solution are:

[0011] 1. By setting up components such as slides, connecting rods and clamps, the measuring device can be effectively fixed on the flange to prevent shaking during measurement and reduce measurement errors;

[0012] 2. By setting a slide rule, a pair of gears and a circular measuring needle, when measuring the hole diameter, it can fit the inner wall more closely, reduce the error of measuring the hole diameter, and improve the measurement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
