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 assembly design and relates to an automatic detection device for the appearance of a brazing grid frame. The automatic detection device comprises an automatic feeding device, a mechanical clamping arm which is arranged beside the automatic feeding device and is used for clamping a to-be-detected grid frame and a weld joint detection mechanism which is arranged below the mechanical clamping arm; the automatic feeding mechanism is used for automatically storing and taking the grid frame and is used for taking the grid frame for testing; the mechanical clamping arm is used for clamping the grid frame stored by the automatic feeding mechanism and can freely change the orientation and angle of the clamped grid frame; the weld joint detection mechanism is used for carrying out weld joint detection on the grid frame detected by a material blockage detection mechanism. During weld joint detection, the automatic detection device can quickly and accurately position each square grid of the grid frame. The automatic detection device has the advantages of greater rapidness and comprehensive detection coverage range compared with a manual detection mode. With the automatic detection device adopted, the work of the manual detection of the weld joint of the grid frame is avoided.

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...
