Description

TECHNICAL FIELD

[0001] The utility model relates to a welding slag detection technical field, specifically a flywheel gear ring assembly welding slag preliminary cleaning detection device. BACKGROUND

[0002] In the automobile manufacturing process, the flywheel gear ring is an important transmission component between the engine and the transmission, and its quality directly affects the power transmission performance and stability of the automobile. In the production process of the flywheel gear ring, the welding process is widely used, but welding slag is easy to remain on the surface of the gear ring after welding. If these welding slag is not detected and removed in time, it may cause imbalance during engine start or high-speed rotation, causing vibration and noise, and even damage to other related parts, seriously affecting the safety and reliability of the automobile.

[0003] At present, for the detection of flywheel gear ring welding slag, the artificial visual detection method is mostly used. This method is not only inefficient, but also greatly affected by human factors, and is easy to miss and misjudge. At the same time, it is difficult to effectively detect the welding slag hidden in the tooth groove or the small welding slag.

[0017] In order to make the purpose, technical scheme and advantages of the flywheel ring gear assembly welding slag preliminary cleaning detection device more clear and understandable, the following will further detail the flywheel ring gear assembly welding slag preliminary cleaning detection device with reference to the drawings and examples.

[0018] In one embodiment, as shown in Figs. 1-2 A flywheel ring gear assembly welding slag preliminary cleaning detection device, comprising a base 11, a flywheel ring gear assembly 14 and a detection piece 16, a positioning hole 15 is formed through the middle position of the flywheel ring gear assembly 14, a positioning seat 12 is fixed to the middle position of the upper end of the base 11, a positioning shaft 13 matched with the positioning hole 15 is fixed to the middle position of the upper end of the positioning seat 12, the detection piece 16 is used for preliminary cleaning detection of the outer wall ring gear of the flywheel ring gear assembly 14, and the base 11 and the detection piece 16 are steel parts.

[0019] In the embodiment, the tooth profile of the detection piece 16 is determined according to the tooth profile parameter of the flywheel ring gear assembly 14, and the detection piece 16 is positioned through the cooperation of the positioning hole 15 and the positioning shaft 13, vertically moves up and down through the flywheel ring gear assembly 14, and the welding slag is easily scraped off the base 11; if the welding slag is not easy to clean, the detection piece 16 cannot be moved down, and needs to be sent to the existing ring gear cleaning device; if the detection piece 16 can be vertically moved up and down and no welding slag falls on the base 11, the flywheel ring gear assembly 14 has no welding slag residue.

[0020] In an optional embodiment, the detection piece 16 comprises a detection ring 161, the inner wall of the detection ring 161 is fixed with a detection inner gear ring 162 matched with the outer wall gear ring of the flywheel ring gear assembly 14, and the outer wall of the detection ring 161 is symmetrically fixed with a handle 163.

[0021] It should be noted that the detection inner gear ring 162 is matched with the outer wall gear ring of the flywheel ring gear assembly 14, which ensures the close cooperation between the detection piece 16 and the flywheel ring gear assembly 14, and improves the accuracy of detection. The outer wall of the detection ring 161 is symmetrically fixed with the handle 163, which is convenient for the operator to hold and operate the detection piece.

[0022] In an optional embodiment, the outer wall of the handle 163 is fixed with a rubber soft pad, and the surface of the rubber soft pad is provided with anti-skid lines.

[0023] It should be noted that the outer wall of the handle 163 is fixed with a rubber soft pad, which increases the comfort of holding and reduces hand fatigue during long-time operation.

[0024] The surface of the rubber soft pad is provided with anti-skid lines, which improves the safety during operation and prevents accidents caused by hand slipping.

[0025] In an optional embodiment, the bottom end corners of the base 11 are fixed with supporting legs, and the bottom end of the supporting leg is provided with an anti-skid layer.

[0026] It should be noted that the bottom end corners of the base 11 are fixed with supporting legs, which not only provides stable support, but also ensures the balance of the device during use.

[0027] The bottom end of the supporting leg is provided with an anti-skid layer, which further improves the stability of the device during use and prevents sliding or tilting caused by a wet or uneven workbench surface.

[0028] The above embodiment discloses a flywheel ring gear assembly welding slag preliminary cleaning and detection device, wherein the flywheel ring gear assembly 14 is matched with the positioning shaft 13 on the base 11 through the positioning hole 15, and precise positioning is achieved. When the detection piece 16 moves vertically up and down, it will scrape the tooth surface, tooth top and tooth groove of the flywheel ring gear assembly 14.

[0029] If there are easily cleaned welding slag on the ring gear, the welding slag will be scraped off and fall on the upper surface of the base 11.

[0030] If there are not easily cleaned welding slag on the ring gear, the detection piece 16 will not be able to move down smoothly, at which time the flywheel ring gear assembly 14 needs to be sent to the existing ring gear cleaning device for further cleaning.

[0031] If the detection piece 16 can move up and down vertically smoothly, and no welding slag falls on the upper surface of the base 11, it means that the tooth surface, tooth top and tooth groove of the flywheel ring gear assembly 14 are free of welding slag.

[0032] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
