Technical Field
[0001] The utility model belongs to the technical field of casting sample clamping tooling, and in particular relates to a sample clamping tooling for testing the air permeability of a coating. Background Art
[0002] As we all know, the lost foam casting process requires the use of water-based paint to paint the model, and then put it into the sandbox for casting after drying. Whether the air permeability of the paint meets the technical requirements becomes a key factor affecting the quality of casting products. Therefore, the detection of paint permeability in the foundry industry is listed as an important quality control method. At present, different companies in the industry use different testing equipment and testing tools to meet the corresponding testing needs, and the testing efficiency and convenience are very different. Utility Model Content
[0003] In order to facilitate disassembly and installation, facilitate standardization of the detection process, improve detection efficiency, and reduce human detection errors, the utility model proposes a coating air permeability detection sample clamping tooling.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A coating permeability testing sample clamping tool comprises a loading sleeve, an upper pressure cover and a positioning pin.
[0006] The carrier sleeve is located at the test end of the air permeability tester, the upper pressure cover is located on the upper side of the carrier sleeve, the positioning pins are located in the positioning holes of the carrier sleeve and the upper pressure cover, and the carrier sleeve and the upper pressure cover are fixed by the positioning pins.
[0007] The sample to be tested is placed in the center of the carrier sleeve.
[0008] The above-mentioned coating permeability test sample clamping tool, the carrier sleeve and the upper pressure cover are both cylindrical with a base, including a base and a barrel; the carrier sleeve and the upper pressure cover have the same base, which is a circular ring with two symmetrical notches, and part of the circular ring is cut off along the line parallel to the two notches; the inner diameter and outer diameter of the barrel of the carrier sleeve and the upper pressure cover are respectively the same; the height of the barrel of the carrier sleeve is greater than the height of the barrel of the upper pressure cover.
[0009] The above-mentioned coating permeability test sample clamping tool has a height of 91.5mm for the carrier sleeve, an inner diameter of 58mm for the carrier sleeve, an outer diameter of 65mm for the carrier sleeve, a height of 31.5mm for the upper pressure cover, a base thickness of 6mm, a notch depth of 8mm, a notch root chamfer of R3.5, an outer diameter of 113.2mm for the base, and a distance from the chord of the cut-off portion of the ring to the center of the circle of 45mm.
[0010] In the above-mentioned coating permeability test sample clamping tool, the positioning pin is a cylinder.
[0011] In the above-mentioned coating permeability test sample clamping tool, the positioning pin has a diameter of 6 mm and a length of 20 mm.
[0012] The beneficial effects of the utility model are:
[0013] A coating permeability test sample clamping tool. After the load sleeve is installed on the test end of the permeability tester, the permeability sample can be quickly placed in the center of the sleeve, and then the upper pressure cover is placed and the positioning pin is inserted to fix it. At this time, the permeability test can be carried out, and the tool is disassembled in reverse order after the test. The test process is standardized, the test efficiency is high, and the human influence factor is small. BRIEF DESCRIPTION OF THE DRAWINGS
