Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a transfer frame for fluorescent penetration testing of precision thin-walled plate-like metal parts. Background Art

[0002] Some precision thin-walled metal parts often use fluorescent penetrant detection for surface defects. For parts with smaller batches, individual parts are tested independently. However, when the batch size of parts is large, in order to improve the detection efficiency, the parts are tied with steel wire or stacked in a plastic frame, and then placed in the penetration tank and cleaning tank. This can easily cause collisions between parts, resulting in scratches and other defects on the surface of the parts, and even deformation or dents of the parts in severe cases; it can also easily cause the penetrant to not fully penetrate the parts or the parts to be insufficiently cleaned, affecting the inspection results.

[0028] The present invention is achieved through the following technical solutions.

[0029] As shown in the figure, the transfer frame for fluorescent penetrant testing of precision thin-walled metal parts includes a frame body 1, a layer partition 2, a transverse partition 3, and a longitudinal partition 4.

[0030] The frame 1 includes a side plate 1-1, a main beam 1-2, a lifting ring 1-3, a bottom plate 1-4, an intermediate baffle 1-5, a small baffle 1-6, a large baffle 1-7, and a reinforcing rod 1-8, wherein the main beam 1-2 is connected to the side plate 1-1 through the square holes at both ends of the upper part of the side plate 1-1, and is fixed with screws through the screw holes on the end surface of the side plate 1-1; a plurality of reinforcing rods 1-8 are connected to the side plate 1-1 through the square grooves on the bottom surface of the side plate 1-1, and are fixed with screws; The plate 1-4 is placed between the two side plates 1-1 and on the reinforcing rod 1-8 at the bottom, and is fixed to the reinforcing rod 1-8 with screws; the middle baffle 1-5 is inserted through the middle vertical grooves on the side plates 1-1 on both sides, and is fixed with screws through the screw holes of the side plates 1-1; the lifting ring 1-3 is connected through the mounting holes on the main beam 1-2 and is locked with nuts; the small baffle 1-6 and the large baffle 1-7 are respectively connected through the mounting holes on the side plates 1-1 on both sides, and are fixed with screws.

[0031] The side panels 1-1 are provided with a number of U-shaped vertical grooves at equal intervals, the purpose of which is to facilitate the rapid insertion of the transverse partition 3 into the side panels 1-1 on both sides, so as to perform transverse division according to the size of the transported parts; similarly, the transverse partition 3 is also provided with a number of U-shaped vertical grooves at equal intervals, the purpose of which is also to facilitate the rapid insertion of the longitudinal partition 4 into the transverse partition 3, so as to perform longitudinal division according to the size of the transported parts.

[0032] There are square holes at both ends of the side plate 1-1, and the main beam 1-2 passes through and is fixed with screws. The purpose is to increase the strength of the transfer frame and facilitate its positioning and installation.

[0033] The side plate 1-1 has three layers of inclined U-shaped transverse grooves in the middle, and the height of the U-shaped transverse grooves on the side plate 1-1 close to the middle baffle 1-5 is higher than the height of the end away from the middle baffle 1-5, so that the adjustment layer partition 2 is inclined after installation. The purpose is to adjust the installation height of the layer partition 2 and make the layer partition 2 appear high in the middle near the transfer frame and low at both ends, so as to facilitate the rapid outflow of the permeate and the cleaning liquid and reduce the generation of liquid accumulation.

[0034] The purpose of the several reinforcing rods 1-8 fixed under the bottom plate 1-4 is to increase the strength of the transfer frame and prevent deformation.

[0035] The lifting ring 1-3 is installed in the middle of the main beams 1-2 on both sides for the purpose of facilitating hanging and transportation.

[0036] The small baffle 1-6 and the large baffle 1-7 are installed on both sides of the side plate 1-1, and their purpose is to increase the strength of the transfer frame.

[0037] The layer partition 2 is inserted from the small baffle 1-6 and the large baffle 1-7 along the transverse groove in the middle of the side plate 1-1, one end is inserted into the middle transverse groove of the middle baffle 1-5, and the other end is blocked on the side of the side plate 1-1, the purpose of which is to divide the transfer frame into two parts, upper and lower parts.

[0038] The partition plate 2 is of T-shaped structure, the purpose of which is to facilitate the insertion and removal of the partition plate 2 and to prevent the intermediate baffles 1-5 from being bent due to excessive force when the partition plate 2 is inserted.

[0039] The transverse partition 3 is inserted into the U-shaped vertical grooves on the side plates 1 - 1 on both sides, and a suitable U-shaped vertical groove position is selected according to the size of the installed parts, and the U-shaped vertical groove is inserted to perform transverse division.

[0040] The longitudinal partitions 4 are inserted through the evenly distributed U-shaped vertical grooves on the transverse partitions 3 according to the size of the loaded parts to perform longitudinal division.

[0041] After a certain number of transverse partitions 3 and longitudinal partitions 4 are inserted according to the size and quantity of the transported parts, an independent square space is formed. The purpose is to place the transported parts in the independent space without contacting each other, thereby preventing the transported parts from being scratched or deformed on the surface due to collision during transportation, and also allowing the transported parts to be completely immersed in the penetrant and cleaning liquid.

[0042] Except for the lifting rings 1-3 and the screws and nuts for fixing, the remaining parts are made of polypropylene (PP) plates, in order to prevent the corrosion of the transfer frame by the penetrating liquid and the cleaning liquid; to reduce the weight of the transfer frame; and to protect the transferred parts from surface scratches or deformation when they collide with the transfer frame during the transfer process.

[0043] A large number of circular holes are opened on the bottom plate 1-4, the middle baffle 1-5, the small baffle 1-6, the large baffle 1-7, the layer partition 2 and the cross partition 3, the purpose of which is to reduce the weight of each part, facilitate the rapid outflow of the penetrating liquid and the cleaning liquid and prevent the generation of liquid accumulation.

[0044] In actual use, the transfer frame for fluorescent penetration testing of precision thin-walled plate-like metal parts of the present invention is used, and its working principle is as follows: 1. Select a certain number of transverse partitions 3 and longitudinal partitions 4 according to the size and quantity of the transferred parts; 2. Select the appropriate U-shaped vertical groove of the side plate 1-1 for the transverse partition 3 according to the thickness of the transferred parts, and insert it along the U-shaped vertical groove; 3. Select the appropriate U-shaped vertical groove of the transverse partition 3 for the longitudinal partition 4 according to the length of the transferred parts, and insert it along the U-shaped vertical groove; 4. Place the transferred parts in the grid formed by the transverse partitions 3 and the longitudinal partitions 4; 5. Insert the layer partition 2 along the middle U-shaped transverse grooves at both ends of the side plate 1-1 according to the actual position, until one end is inserted into the middle U-shaped transverse groove of the middle baffle 1-5, 6. Repeat the above 1 to 5 processes on the upper layer formed by the layer partition 2. 7. After the transfer is completed, take out the transferred parts, and then take out the transverse partition 3, longitudinal partition 4 and layer partition 2.
