Technical Field
[0001] This utility model relates to the field of EMU testing technology, specifically to a side-sliding door measuring fixture. Background Technology
[0002] During the opening and closing of the side-sliding doors on high-speed trains, a certain clearance is required between the moving parts on the door panel, the moving parts of the opening and closing mechanism, and the mounting and fixing components of the side-sliding doors. Insufficient clearance can lead to impact and friction between the moving parts and the mounting and fixing components, causing obstruction of the side-sliding doors' opening and closing, increasing passenger boarding and alighting time, and significantly disrupting railway transport order. The main measure to prevent impact and friction between the moving parts of the side-sliding doors and the mounting and fixing components is to ensure that there is a sufficient safety clearance between them. Specifically, during vehicle maintenance, measuring tools are used to measure the clearances of relevant parts to determine whether the clearances meet safety standards.

By placing the measuring feeler gauge 1, the measuring block 2, the measuring rod 3, and the reflector used for testing in different areas of the storage base 4, the tools required for the corresponding measurement positions can be quickly located.
[0020] Preferably, each of the second placement slots 42 has two semi-circular gripping slots 43 symmetrically arranged in the middle. The gripping slots 43 are connected to the corresponding second placement slots 42, facilitating the insertion of fingers to remove the measuring feeler gauge 1, the measuring block 2, and the measuring rod 3 from the corresponding second placement slots 42. The gripping slots 43 are configured as quarter-spherical grooves with a radius of 1 mm.
[0021] like Figure 5 As shown, Figure 5 The image shows a structural view of the measuring feeler gauge 1. The measuring feeler gauge 1 is configured as a strip-shaped plate extending along a straight line. The measuring feeler gauge 1 includes a first measuring segment 11, a second measuring segment 12, and a body segment 13 arranged sequentially.

The measuring block 2 is a cuboid block with a first measuring end and a second measuring end at its two ends. The first measuring end is provided with a first measuring plate 21, and the second measuring end is provided with a second measuring plate 22. The first measuring plate 21 and the second measuring plate 22 have the same thickness. The first measuring plate 21 has a first measuring groove 23 and a first clearance groove 24 on both sides to form the first measuring plate 21 at the first measuring end. The second measuring plate 22 has a second measuring groove 25 and a second clearance groove 26 on both sides to form the second measuring plate 22 at the second measuring end. The first measuring groove 23 and the second measuring groove 25 are located on the same side of the measuring block 2, and the first clearance groove 24 and the second clearance groove 26 are located on the same side of the measuring block 2.
[0025] The thickness of the first measuring plate 21 and the second measuring plate 22 is set to 2mm. The first measuring groove 23 and the second measuring groove 25 are positioned by engaging with the position switch. The first clearance groove 24 and the second clearance groove 26 avoid other components, so as to ensure that the exposed size of the red line of the position switch on the side sliding door meets the requirement of 1mm to 2mm.
[0026] Specifically, the measuring block 2 is a metal block with dimensions of 45mm in length, 15mm in width, and 10mm in height. A first measuring groove 23 and a second measuring groove 25, each 1mm deep and 3.5mm long, are designed at both ends of the upper surface of the metal block. A first clearance groove 24, 7mm deep and 8.5mm long, is designed on the left side of the lower surface of the metal block, and a second clearance groove 26, 7mm deep and 3.5mm long, is designed on the right side of the lower surface of the metal block.

[0032] The storage base 4 is a rectangular plate. The protective box 5 has an installation groove that mates with the storage base 4. The storage base 4 has a positioning groove 44 on its side. The positioning groove 44 extends through the thickness of the storage base 4. A positioning block 51 is provided on the groove wall of the installation groove. The positioning block 51 is located in the positioning groove 44, thereby ensuring that the storage base 4 is stably positioned in the protective box 5.
[0033] Specifically, the storage base 4 is a plastic part with a length, width, and height of 200mm, 60mm, and 16mm respectively. The protective box 5 is a transparent plastic box with a length, width, and height of 202mm, 65mm, and 1.9mm respectively. The protective box 5 can be set to open with a flip-top, and the flip-top has a buckle to lock it closed.
[0034] The measuring feeler gauge 1, the measuring block 2, and the measuring rod 3 are all made of stainless steel, which can improve the problem of easy corrosion and wear of measuring tools.
[0035] The measuring feeler gauge 1, the measuring block 2, and the measuring rod 3 are ingeniously designed to enter specific narrow areas, enabling full-coverage measurement of safety gaps in relevant parts of the EMU side sliding door. The measurement coverage is wide, and it can eliminate human measurement errors in specific parts, greatly improving measurement accuracy.
[0036] This utility model integrates multiple tools into a centralized location, enabling multi-functional testing. It is highly practical, easy to find and use, and allows for more convenient measurement. In actual testing, it can save two-thirds of the measurement time and significantly improve measurement efficiency.
