Description

Technical Field

[0001] The invention belongs to the field of bearing ring detection, and in particular relates to a bearing ring defect detection device. Background Art

[0002] Common bearings are primarily composed of four basic components: balls, inner rings, outer rings, and cages. Bearing rings, which have raceways on the inner ring surface and outer rings on the outer ring surface, are hollow cylindrical sleeves. Excluding chamfers, they consist of four surfaces: the inner ring surface, outer ring surface, upper end face, and lower end face.

[0003] During the production process, defects such as spots, rolling, peeling, abrasions, burning, corrosion, bumps, dents, indentations, and cracks may appear on the surface of bearing rings, which will reduce their service life and stability. Therefore, before leaving the factory, the products must be strictly inspected for quality and unqualified products with defects must be eliminated.

[0004] In the existing technology, most bearing ring detection devices can only detect one or two surfaces of the bearing ring at the same time. After the detection, they need to be turned over manually. In addition, one device cannot detect the inner ring surface and the outer ring surface of the bearing ring at the same time. Usually, it is necessary to replace the equipment to perform a comprehensive inspection of the bearing ring. The inspection process is cumbersome, which limits the inspection efficiency of the bearing ring. Summary of the Invention

At the same time, the outer transmission component 72 can drive the bearing ring body 4 to rotate horizontally, so that the industrial camera 11 can perform a comprehensive inspection of the bearing ring body 4.

[0044] like Figure 4 and Figure 6-Figure 8 As shown, a bearing ring defect detection device provided by the present invention is provided. In order to improve the installation stability of the bearing ring body 4 and prevent the bearing ring body 4 from falling off the support plate 73, in this embodiment, the inner clamping assembly 71 also includes a limiting mechanism 9, and the limiting mechanism 9 includes a plurality of limiting rod assemblies 91. The plurality of limiting rod assemblies 91 are all installed on the top of the first transmission roller 714, and the plurality of limiting rod assemblies 91 are evenly distributed around the axis of the first transmission roller 714. The distance from the bottom surface of the output end of the limiting rod assembly 91 to the surface of the support plate 73 is equal to the thickness of the bearing ring body 4.

[0045] After the bearing ring body 4 is placed on the support plate 73 and the first transmission roller 714 is in contact with the inner side surface of the bearing ring body 4, the output end of the limiting rod assembly 91 is in contact with the upper surface of the bearing ring body 4, thereby limiting the bearing ring body 4 and preventing the bearing ring body 4 from falling off from above the first transmission roller 714.

[0046] like Figure 4 and Figure 6-Figure 8 The figure shows a bearing ring defect detection device provided by the present invention. In order to more conveniently install the bearing ring body 4, in this embodiment, the limiting rod assembly 91 can be set to be retractable. When the bearing ring body 4 is not clamped, the limiting rod assembly 91 is completely retracted into the first transmission roller 714, thereby facilitating the removal and placement of the bearing ring body 4. When the first transmission roller 714 contacts the bearing ring body 4, the limiting rod assembly 91 extends from the first transmission roller 714 and limits the vertical direction of the bearing ring body 4 to prevent the bearing ring body 4 from falling off. Therefore, in this embodiment, the limiting rod assembly 91 includes a sliding rod 912 slidably connected to the first transmission roller 714, an active cavity 916 is defined inside the first transmission roller 714, a blocking piece 915 is fixedly connected to the side of the sliding rod 912 located in the active cavity 916, a compression spring 914 is connected between the blocking piece 915 and the side wall of the active cavity 916 facing away from the axis of the first transmission roller 714, and one end of the sliding rod 912 extending out of the first transmission roller 714 is rotatably connected to a guide roller 911, a receiving groove 913 adapted to the guide roller 911 is defined on the side of the first transmission roller 714, and initially, the guide roller 911 is located in the receiving groove 913; In order to facilitate the extension of the limit rod assembly 91 from the first transmission roller 714, the limit mechanism 9 also includes a linkage mechanism, which includes a center hole 92 opened on the first transmission roller 714, and the interior of the center hole 92 is slidably connected to a drive rod 93, and the end of the drive rod 93 is provided with a conical surface, and one end of all center holes 92 is in contact with the conical surface.

When the first transmission roller 714 is not blocked, the driving block 97 drives the driving rod 93 to move horizontally under the dead weight of the driving rod 93. The driving rod 93 drives the first transmission roller 714 to move horizontally, so that the first transmission roller 714 approaches the inner side surface of the bearing ring body 4. When the first transmission roller 714 is blocked by the bearing ring body 4, the driving block 97 squeezes the driving rod 93 through the guide inclined surface 96 and drives the driving rod 93 to rise.
