However, with the development of industry, people have higher and higher requirements for the outer diameter accuracy of tubular materials. Low-precision tubular materials can no longer meet people's daily needs. High-precision tubular materials often become people's new favorites. Therefore, manufacturers need to continuously measure the outer diameter of continuous tubular materials during the processing and production of tubular materials to ensure that they can meet certain accuracy requirements. However, the current technical level of measuring the outer diameter of tubular materials is still limited to accurate size measurement by calipers or go / no-go gauges in static state, and it is impossible to measure the accurate circumferential outer diameter of tubular materials during non-stop continuous production. Even by laser caliper, it can only measure the size of a specific position and cannot measure the size of the entire circumference. Therefore, it is an inevitable trend for technicians in this field to develop an online continuous round tube accurate diameter measuring device that can measure the accurate outer diameter of tubular materials during non-stop continuous production of the production line.

[0030] Figure 4 It is a structural schematic diagram of the annular frame hj of the first embodiment of the utility model.
[0031] like Figure 3 and Figure 4As shown, according to one aspect of the specific implementation of the first embodiment of the utility model, the laser rangefinder jcc is configured as a combination of a laser transmitter and a laser receiver capable of emitting a parallel planar laser beam, and two devices are arranged oppositely on both sides of the part to be measured to block the parallel planar laser beam to produce a shadow area, and the laser receiver identifies the size of the shadow area to calculate the precise size of the part to be measured. In this embodiment, the laser rangefinder jcc is distributed on both sides of the tube gc, and the tube gc blocks the parallel planar laser beam to produce a shadow area so that the laser rangefinder jcc can measure the precise outer diameter size of the tube gc.
