Problems solved by technology

Due to the small space of the grid grid, the manual visual inspection of the quality of the brazing seam of the grid is extremely low in detection efficiency, heavy in the detection workload, increases the production cost, and is prone to false detection and missed detection.
[0003] The appearance inspection of the grid has always been carried out by manual visual inspection, the detection efficiency is not high, and it is easy to cause visual fatigue of the inspectors, resulting in missed inspections and false inspections

Embodiment Construction

[0047] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0048] Such as figure 1 As shown, the detection device includes an automatic feeding device 2, a mechanical clamping arm 3 installed next to the automatic feeding device 2 for clamping the grid 1 to be detected, and a positioner installed at the output end of the automatic feeding device 2 in turn. Mechanism 5 and blockage detection mechanism 6, and weld seam detection mechanism 4 below the mechanical clamping arm 3.

[0049] The automatic feeding mechanism 2 is used for automatic access to the grid and for detection and access;

[0050] The mechanical clamping arm 3 is used to clamp the grid stored in the automatic feeding mechanism and can freely change the orientation and angle of the clamped grid;

[0051] The positioning mechanism 5 is used to identify the surface with lettering on the grid clamped by the mechanical clamping arm from the automat...

Abstract

The invention belongs to the technical field of nuclear fuel component design, and specifically relates to an automatic detection device for the appearance of a brazing grid, including an automatic feeding device, a mechanical clamping arm and a mechanical The welding seam detection mechanism under the clamping arm; the automatic feeding mechanism is used for automatic access to the grid and used for inspection, and the mechanical clamping arm is used to clamp the grid stored in the automatic feeding mechanism and can freely change the clamped With the orientation and angle of the grid, the weld detection mechanism is used to detect the weld of the grid after the detection of the blocking material detection mechanism. During the weld detection, it can quickly and accurately locate each grid of the grid, which is relatively The manual inspection method is faster and the inspection coverage is comprehensive, thereby eliminating the need for manual inspection of the grid welds.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel assembly design, and in particular relates to a grid appearance detection device in the assembly. Background technique [0002] The grid in the component is a special-purpose metal workpiece. In order to meet the requirements of welding strength and surface smoothness, the grid adopts a brazing process, and each grid of the grid needs to be inspected for welds. Due to the small space of the lattice grid, manual visual inspection of the quality of the brazing seam of the grid is extremely low in detection efficiency, heavy in the detection workload, increases in production costs, and is prone to false detection and missed detection. [0003] The visual inspection of the grid has always been carried out by manual visual inspection, which is not efficient, and it is easy to cause visual fatigue of the inspectors, resulting in missed inspections and false inspections. [0004] It is necessary to...
