Description

Technical Field

[0001] The invention relates to the technical field of three-way grooved pipe fittings, in particular to a three-way grooved pipe fitting wall thickness uniformity detection device. Background Art

[0002] Tee pipe fittings are a type of pipe connector, used at the main pipe and branch pipe, and are divided into equal diameter and different diameter. During the production process of existing three-way grooved pipe fittings, it is necessary to measure the wall thickness of the three-way grooved pipe fittings to prevent the thickness from not meeting the standard, which may cause leakage and rupture of the three-way grooved pipe fittings during subsequent use, resulting in production accidents and losses. The existing three-way grooved pipe fittings measure the wall thickness manually by measuring the wall of the pipe fittings one-sided multiple times, and then calculate the average value after recording the data. Manually measuring the wall thickness of the pipe fittings multiple times is likely to result in multiple measurements near the same position, and the difference in data cannot be distinguished, resulting in deviations in the recorded data.

[0003] To this end, a new type of three-way groove pipe wall thickness uniformity detection equipment (China Patent Publication No.: CN209166299U) is proposed in the market, which includes a measuring plate and a three-way groove pipe body. The device inserts the measuring plate into the three-way groove pipe body, pulls the limit block on the measuring plate, and deforms the telescopic rod and the reset spring connected to the limit block. The elastic potential energy of the deformation of the reset spring is used to drive the limit block to limit the inner wall of the three-way groove pipe body, and then rotates the handle to drive the threaded rod to rotate, and the threaded rod drives the measuring block to reciprocate up and down, wherein the movable block assists the measuring block to reciprocate up and down, and then calculates the thickness of the three-way groove pipe body wall by reading the scale corresponding to the level of the measuring block and the scale. When it is necessary to calculate the average value of the three-way groove pipe body wall thickness, the device is rotated to measure the thickness of different unknown three-way groove pipe body walls.

[0004] However, in the above-mentioned disclosed technical solution, the detection equipment does not have a structure to support the pipeline. When detecting the pipe wall thickness at different positions, it is necessary to hold the pipe and move it forward and backward. If the pipe is not in a horizontal straight line during movement, it is necessary to readjust the position of the measuring block, which not only reduces the measurement efficiency but also affects the measurement accuracy. For this reason, there are improved technologies in the market, especially a new type of three-way grooved pipe wall thickness uniformity detection equipment (China Patent Publication No.: CN220356242U), including a mounting plate and a measuring plate, the top and bottom of the measuring plate are fixed with connecting blocks, and the top of the mounting plate is fixed with a connecting block. A connecting frame is fixedly provided, the connecting frame is fixedly connected to one side of the connecting block, two threaded rods are movably provided in the connecting block, and measuring blocks are movably provided on the two threaded rods. The improved technology, by providing components such as a vertical plate, a first supporting block, a spring and an arc plate, places the pipeline to be tested in the through groove when measuring the inner wall thickness of the pipeline, and the arc plate is pushed by a plurality of springs to move in a direction close to the pipeline, and drives a plurality of ball bearings to fit the outer wall of the pipeline, and the vertical plate and the first supporting block can support the pipeline, and when measuring the inner wall thickness at different positions, the pipeline will be displaced on the same horizontal line, and there is no need to adjust the position of the measuring block, thereby improving the measurement efficiency; However, the existing three-way grooved pipe wall thickness uniformity detection equipment, including the aforementioned public technology and the above-mentioned improved technology, still has the following disadvantages: First, the structure for measuring thickness requires manual operation and manual visual reading, which is inefficient and prone to errors; Second, the three-way grooved pipe has three pipe openings, and the wall thickness of the three pipe openings needs to be measured. Each measurement requires manual reversal or re-clamping, which is very inconvenient.
