[0002] Pipes are common products ranging from industrial machinery to daily necessities. Industrial pipes are made of a variety of materials, so different pipe manufacturers are required for production. During the production process of pipes, it is necessary to Sampling inspection of the pipeline to check whether the various indicators of the pipeline are qualified, including the actual diameter of the inner diameter of the pipeline. In the prior art, when measuring the inner diameter of a large pipeline, it is extremely inconvenient to measure the inner diameter because the inside is curved, and the measuring tool is in use. When the diameter of the pipe cannot be adjusted, it can only be replaced with other larger gear measuring equipment, which will increase the cost

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] see Figure 1-5 , the present invention provides an extensible clamping measuring device for pipe diameter measurement: it includes a measuring rod 1, the measuring rod 1 is configured as a cylindrical structure, and four placement slots 2 are symmetrically opened on the outer peripheral surface of the center of the measuring rod 1 , both sides of the placement groove 2 of the measuring rod 1 are provided with four chute 3 symmetrically, two sides of th...

The invention relates to the technical field of pipeline diameter measurement, in particular to an extensibility clamping measurement device for pipeline diameter measurement, which comprises a measurement rod. The measurement rod is of a cylindrical structure, four placement grooves are symmetrically formed in the outer circumferential surface of the center of the measurement rod, and four sliding grooves are symmetrically formed in the two sides of each placement groove of the measurement rod. According to the device, four contact heads are controlled to extend outwards at the same time through two lead screws and then make contact with the inner wall of a pipeline, the contact head on one side drives a pull rope to drag a square rod to drive the position of a pointer in a dial drum to change, then the pointer is pulled out for reading, and use is convenient; meanwhile, according to the fact that balls can perform smooth rotation detection on the inner diameter of the pipeline and whether pipeline deformation exists or not, when a sleeve arm slides towards the two sides through a lead screw, an arc-shaped groove of a movable arm extrudes an arc-shaped plate, then the arc-shaped plate is inserted into the other arc-shaped groove through a torsion spring, when the diameter measuring range is extended, positioning use is automatically performed, and operation is simple.

During the production process of pipes, the produced Sampling inspection of the pipeline to check whether the various indicators of the pipeline are qualified, including the actual diameter of the inner diameter of the pipeline. In the prior art, when measuring the inner diameter of a large pipeline, it is extremely inconvenient to measure the inside because of the arc shape, and the measuring tool is in use. At the same time, it cannot be adjusted according to the diameter of the pipeline, and it can only be replaced with other larger gear measuring equipment, which will...
