Background
In the pressure vessel manufacturing industry, reference lines, vertical lines, horizontal lines, diagonal lines, bisectors, center lines, etc. of the vessels need to be determined in advance and verified to avoid erroneous marking and to find positions for subsequent processing (e.g., inner and outer vessel assembly).
Existing pressure vessel manufacturers are basically manually site-directed scored by a score line personnel. When the fixed position of the heat-insulating supporting block of the inner container is determined by the inner container and the open position of the heat-insulating supporting block of the outer container is inserted into the inner container, the manual scribing is to measure the arc length of the container body to determine the position, and tools such as a limit ruler, a scriber, a scribing gauge, a line, a heavy cone, a tape measure and the like are needed in the manual scribing process, and the operation steps comprise:
(1) the circumference of the outer wall is read out by encircling the measuring tape along the outer wall of the tank body.
(2) And calculating the corresponding arc length of each degree.
(3) According to the degree of the drawing, the graduation is measured by a tape measure.
(4) The measured graduation marks are connected by a limit ruler and a scriber.
(5) And in the axial direction of the tank body, a tape measure is used for finding the position of each hole from the datum line and proofing and punching holes.
Therefore, the operation method of manual scribing is complicated, and the tool mainly relied on in the whole measuring process is the tape, and the tape have relative errors due to the fact that the precision of the tape is 1mm, and the error of manual scribing is large. In addition, the deformation exists in the prior large and medium pressure tanks, so that the difference value between the scribing position and the theoretical position is further increased. The position matching degree of the inner tank and the outer tank heat insulation supporting blocks is insufficient, and the stability of the container in the transportation and use process is affected. Meanwhile, when the top ends of the medium and large pressure vessels are marked, operators need to ascend, so that potential safety hazards exist.
Although some small containers with high precision are adopted to be scored on a platform, the method has relatively large space limitation and cannot meet the requirements of scoring the conventional containers.
Among the prior art, 104526674A discloses a four-axis numerical control marking machine in 2015.04.22, and it includes parallel arrangement's product guide rail and marking off guide rail, is equipped with the product rolling device that at least two cooperations used on the product guide rail, installs the walking base that strikes a point on the marking off guide rail, is provided with the controller on the base, including along X, Y, Z axle removal's drive arrangement, still include with the rotatory detection device of W axle that the controller corresponds. The guide rail supports the product, when the angle data detected by the W-axis rotation detection device is a required angle, the guide rail can automatically stop, the controller sends a signal, the product stops rolling, the X, Y, Z axis and the corresponding device are started, and the dotting and scribing requirements of the product are completed according to the process requirements set in the controller. The device mainly utilizes the cooperation of inclination angle sensor and inclination angle detection device and controller to realize the dotting marking of product.
The above-described marking machine in patent document is different from the principle and structure of the present application, although it is also capable of marking a dot on the surface of a product.
