TECHNICAL FIELD

[0001] The utility model relates to the processing field of precision valve, especially a small plane roughness detection frock of spherical part. BACKGROUND

[0002] The valve core of precision valve is a spherical part with a small plane, and the surface roughness of the small plane needs to be detected in the manufacturing process. The small plane roughness of the spherical part must be detected after the small plane is leveled and fixed, but the existing roughness measurement adopts V-block positioning, and the existing known technology cannot quickly level and fix the small plane of the spherical part, which limits the small plane roughness detection of the spherical part and causes unqualified product quality. SUMMARY

[0003] In order to eliminate the quality unqualification caused by the inability to detect the surface roughness of the small plane of the spherical part with a small plane, the utility model provides a small plane roughness detection frock of spherical part, which can not only level the small plane of the spherical part, but also quickly fix the spherical part, and realize the small plane roughness detection of the spherical part.

[0004] The utility model solves the technical scheme that a small plane roughness detection frock of spherical part adopts, frock design has a parallel plane with the spherical part mounting surface, and the parallel plane is used for quick leveling of the spherical part; the frock is made of spring steel material, and is designed with an elastic through hole, the elastic hole diameter is slightly smaller than the diameter of the spherical part in the natural state, one side of the elastic through hole is opened into a straight groove, the other side is provided with a water drop groove, the hole is used for mounting the spherical part, and the elastic hole is used for fixing the part after leveling the part; the spherical part mounting surface of the frock is designed with a sunken plane, which is convenient for removing the spherical part.

[0005] Compared with the prior art, the utility model has the beneficial effects that the frock scheme with the elastic through hole realizes the leveling and quick fixing of the small plane of the spherical part, realizes the detection of the surface roughness of the small plane of the spherical part, and the frock structure is simple and convenient to use.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0019] As shown in Figures 1-3 , the technical solution provided by the present application is a small plane roughness detection tool for a ball part, which is designed with a surface parallel to the mounting surface of the ball part; the tool has an elastic through hole, the diameter of the elastic hole in a natural state is slightly smaller than the diameter of the ball part, one side of the elastic through hole is provided with a straight slot, and the other side is provided with a water droplet groove; the ball part mounting surface of the tool is designed with a sunken surface.

[0020] As shown in Figures 4-9 , the detection process of the small plane roughness detection tool for the ball part includes four steps of leveling the small plane ball part, leveling and fixing the small plane roughness detection tool, turning over the tool and detecting, and discharging, which are as follows:

[0021] Leveling the small plane ball part, as shown in Figure 4 and Figure 5 , the small plane of the small plane ball part (1) is placed downward on the marble surface of the detection machine base (4), so as to realize the leveling of the small plane ball part (1).

[0022] Leveling and fixing the small plane roughness detection tool, as shown in Figure 4 , the small plane ball part (1) is placed downward on the marble surface of the detection machine base (4), so as to realize the leveling of the small plane ball part (1).As shown, the surface of the roughness inspection fixture (2) is facing down and pressed down on the spherical surface of the small flat spherical part (1). The spherical surface guides the small flat spherical part (1) to be pressed into the elastic hole of the roughness inspection fixture (2). When the bottom of the roughness inspection fixture (2) contacts the marble plane of the inspection base (4), the small flat surface of the small flat spherical part (1) is flush with the installation surface of the fixture. At the same time, the elastic hole uses elasticity to fix the position of the small flat spherical part (1).

[0023] Tooling flipped and inspected, such as Figures 7-9 As shown, first flip the roughness inspection fixture (2) so that the mounting surface of the small flat spherical part (1) is facing upwards. Place the roughness inspection fixture (2) with the plane parallel to the mounting surface as the bottom surface on the marble plane of the inspection base (4). At the same time, move the roughness inspection fixture (2) to move the small flat surface of the small flat spherical part (1) under the roughness inspection head (3) to start the roughness inspection.

[0024] After the material is unloaded and the inspection is completed, the roughness inspection fixture (2) is removed from the roughness inspection head (3), and then the part with small flat sphere (1) is taken out from the sunken plane of the roughness inspection fixture (2).
