Embodiment Construction

[0150] figure 1 shows an example for checking the Figure 4 The schematic process of an embodiment of the method 101 for the pre-installation of the cutting ring 1 on the pipe 2 is shown in FIG. Does it meet the requirements in order to achieve a sealed cutting ring screw joint (not shown) and the necessary tightening force for the pipe 2 . Method 101 is carried out with device 3 having at least one optical detection device 4 for detecting 102 image data in detection region 5 (see Figure 4 ).

[0151] according to figure 1 , the method 101 comprises at least the method steps described below, namely first detecting 102 at least first image data of the pipe 2 with the pre-mounted cutting ring 1 introduced at least partially into the detection region 5 . At least a part of the first image data is then evaluated 103 with respect to the position of the cutting ring 1 relative to the pipe 2 and / or the geometrical properties of the pipe 2 and / or the geometrical properties of the...

Abstract

The present invention relates to a method (101) and a device (3) for checking the pre-assembly of a cutting ring (1) on a tube (2). The method (101) comprises: checking the pre-assembly of a cutting ring (1) on a tube (2) with a device (3) having at least one optical detection device (4) for capturing (102) image data in a detection region (5); detecting (102) at least first image data of at leastone tube (2) with the pre-assembled cutting ring (1) partially inserted into the detection area (4); evaluating (103) at least a part of the first image data with respect to a position of the cuttingring (1) to the tube (2) and / or geometric properties of the tube (2) and / or geometric properties of the cutting ring (1).

Description

technical field [0001] The invention relates to a method for checking, in particular for optically checking, the pre-assembly of cutting rings and to a device for checking the pre-assembly of cutting rings. Background technique [0002] Cutting ring screw joints generally have a coupling sleeve, a union nut that can be screwed onto the coupling sleeve, and a cutting ring arranged between the coupling sleeve and the union nut. The cutting ring is firstly pre-mounted on the pipe, in particular in a defined position in the end region of the pipe, before the final installation of the cutting ring screw joint. At least one cutting surface of the cutting ring penetrates at least partially into the surface of the pipe during pre-installation. [0003] The quality of the cutting ring helical engagement can be affected to a significant extent by pre-installation. Important factors determining the quality are the cutting path in the axial direction, the cutting depth in the radial d...
