Description

[0002] At present, the significance of component symmetry detection is to ensure the quality and performance of the product, as well as to improve production efficiency and cost-effectiveness. Symmetry detection can help discover possible defects or defects in the component manufacturing process and ensure that the product meets the specified quality standards. Among the valve body components, the symmetry detection of the valve cover, valve stem, and valve core plate is particularly important, especially the valve core plate. If the circumferential surfaces at both ends of the valve core plate are not symmetrical, there is a problem that the valve body cannot completely block the water. The current methods for detecting the symmetry of the valve core plate are: optical image measurement comparison method, three-coordinate measurement method and vibration analysis. The instruments used in the above methods are relatively precise, and subsequent precise calculations are required to obtain the results of whether they are symmetrical. The detection cost and time consumption are high and need to be improved. Therefore, we propose a component symmetry detection tooling. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution: a tool for detecting symmetry of parts, comprising a valve core plate 2, a clamping structure for clamping the valve core plate 2 and a symmetry detection structure, the clamping structure comprising a base 1, two parallel side plates 4, one side plate 4 is threadedly connected with a bolt handle 3, and the other side plate 4 is fixedly provided with a top stop column 301, the tops of the two side plates 4 are fixed to the bottom of a top seat 5, a plurality of square grooves 501 are equidistantly provided on the horizontal surface of the top seat 5, and a plurality of circular grooves 502 connected to the square grooves 501 are equidistantly provided on the vertical surface of the top seat 5, the symmetry detection structure comprises a plurality of test rods 6, the test rods 6 are inlaid in the square grooves 501, two convex columns 8 of the same size are fixedly provided on the vertical surface of the top seat 5, a pressure plate 7 is movably provided on the vertical surface of the top seat 5, a plurality of clamping cones 702 are fixedly provided on the surface of the pressure plate 7, the clamping cone 702 passes through the circular groove 502 and the cone head of the clamping cone 702 contacts the surface of the pressure plate 7.

[0020] In a specific embodiment of the present invention, a butterfly-shaped rotating handle is provided at one end of the bolt handle 3, and the bolt handle 3 can be manually rotated. The bolt handle 3 and the stop column 301 stop and fix the two ends of the vertical line of the valve core plate 2, and align the circumferential surface of one side of the valve core plate 2 with the test rod 6 vertically. The pressure plate 7 is connected with the convex column 8 by interference fitting. The pressure plate 7 is moved to separate the clamping cone 702 from the clamping groove 601 on the surface of the test rod 6. By pressing each test rod 6, the test rod 6 is fitted with the circumferential surface of one side of the valve core plate 2. The test rod 6 is prevented from moving up and down, thereby ensuring the stability of the contour of the circumferential surface on one side of the valve core plate 2. The valve core plate 2 is then rotated 180° to compare the circumferential surface on the other side of the valve core plate 2 with the circumferential surface contour formed by the test rod 6. It can be clearly and intuitively determined whether the circumferential surfaces on both sides of the valve core plate 2 are symmetrical, thereby intuitively determining whether the valve core plate 2 is symmetrical about the two ends of the midpoint line.

[0021] In the preferred technical solution, a circular hole 701 is provided on the surface of the pressure plate 7 for interference fit with the boss 8. The inner diameter of the circular hole 701 is 0.1 mm smaller than the diameter of the boss 8. The pressure plate 7 and the boss 8 have an interference fit, so that when the pressure plate 7 and the boss 8 are fitted together, a greater friction force is provided to fix the pressure plate 7, thereby making the position of the test rod 6 more stable.

[0022] In the preferred technical solution, an arc head 602 is integrally formed at the bottom of the test rod 6, and a plurality of slots 601 for mating with the clamping cone 702 are equidistantly provided on the surface of the test rod 6. When the clamping cone 702 is mated with the slot 601, the vertical position movement of the test rod 6 is restricted, thereby improving the stability of the test rod 6 after being restricted.

[0023] In the preferred technical solution, the bolt handle 3 and the stop column 301 are arranged horizontally aligned with each other, and the ends of the bolt handle 3 and the stop column 301 are provided with conical heads for clamping the valve core plate 2. The bolt handle 3 and the stop column 301 are both provided with conical heads for stable clamping and installation with the end of the vertical line of the valve core plate 2.

[0024] In the preferred technical solution, the number of test rods 6, square grooves 501, circular grooves 502 and cones 702 are consistent with each other, and the spacing between two adjacent test rods 6 is set to 2 mm. The test rods 6 are set smaller, which is conducive to more precise marking of the contour of the circumferential surface on one side of the valve core plate 2.

[0025] In the preferred technical solution, the cone head diameter of the clamping cone 702 is 0.2 mm smaller than the narrow side width of the clamping groove 601 , so that the cone head of the clamping cone 702 can be fully embedded in the clamping groove 601 .

[0026] To summarize, in this embodiment, the valve core plate 2 is clamped, and a number of test rods 6 are in contact with the circumferential surface of the valve core plate 2 to form a circular surface contour with detectable symmetry. After the valve core plate 2 is rotated 180°, the circumferential surface at the other end of the valve core plate 2 is compared with the circular surface contour with detectable symmetry, thereby intuitively obtaining the result of whether the circular surfaces at both ends of the valve core plate 2 are symmetrical.
