Description

Technical Field

[0001] The utility model relates to the field of bearing manufacturing, in particular to an inspection tool for preventing a rivet retainer from lacking nails. Background Art

[0002] As a deep groove ball bearing, the internal cage is the most important component, and its main functions are:

[0003] 1. Separate the rolling elements of each bearing to prevent direct contact with the rolling elements, so as to minimize friction and heat generation;

[0004] 2. Guide the rolling elements to run on the raceway; 3. Provide lubrication space;

[0005] At present, the types of bearing cage materials include: low carbon steel / stainless steel cage, bakelite / plastic (nylon) cage, brass / bronze / aluminum alloy cage, etc. The most common cage material (low carbon steel) is the rivet cage structure, which is widely used in bearing types. Its characteristics are light weight, high strength, high shock and acceleration resistance, and no operating temperature limit;

[0006] If there are fewer rivets in the rivet cage during press-fitting, the corresponding ball pocket holes cannot be properly fixed after the rivet cage is pressed. The steel balls wrapped in the cage will directly cause the cage ball pockets to rupture when the bearing runs at high speed, causing the bearing to get stuck or fail.

[0007] The tooling designed this time can detect whether there are any missing nails before the rivet retainer is pressed, ensuring the actual correct press-fitting. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide an inspection tool for preventing the rivet retainer from being short of nails.

[0010] An inspection tool for preventing a rivet retainer from lacking nails, comprising:

[0011] A tool body, the tool body comprising a middle kit cavity, wherein a plurality of sleeves are arranged in the middle kit cavity;

[0015] Both ends of the guide cavity are provided with guide holes;

[0016] A cover body is provided at the upper end of the middle sleeve cavity;

[0017] The cover body, the middle sleeve cavity and the lower cavity are assembled up and down by fasteners;

[0018] The tool body is made of energized metal;

[0019] An upper electrical connection port and a lower electrical connection port are respectively arranged on the outer periphery of the tool body.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following structure, the description of the well-known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] like Figure 1 An inspection tool for preventing a rivet retainer from lacking nails as shown in or 2 includes a tool body 100, and the tool body 100 is made of electrified metal material.

[0029] The tool body 100 includes a middle kit cavity 110 , in which a plurality of sleeves 120 are arranged vertically, and in which a conductive pin 130 with a spring 131 is arranged.

[0030] The lower end of the conductive needle 130 extends out of the spring 131 and is connected to the upper end of the conductive aluminum block 140. The conductive aluminum block is arranged in the guide cavity 151 of the lower cavity 150. The two ends of the guide cavity 151 are provided with guide holes 1511. The rivet to be detected extends into the guide hole 1511 at the lower end of the conductive aluminum block 140 and contacts the conductive aluminum block 140.

[0031] A cover body 160 is provided at the upper end of the middle kit cavity 110; the cover body 160, the middle kit cavity 110 and the lower cavity 150 are assembled up and down by fasteners 170; specifically, the fasteners 170 are a first fastener 171 for fixing the cover body 160 and the middle kit cavity 110, and a second fastener 172 for fixing the middle kit cavity 110 and the lower cavity 150.

[0032] An upper electrical connection port 101 and a lower electrical connection port 102 are respectively provided on the outer periphery of the tool body 100 .

[0033] Because of the above structure, the working principle of the utility model is:

[0034] Before the actual press-fitting of the rivet holder, the rivets and the mounting holes will be matched so that the rivets evenly distributed on the holder will be placed upwards. When the upper electrical port 101 and the lower electrical port 102 are normally installed and powered on, the tooling will fall from a high place under the command of the equipment program when passing through the inspection station, so that the evenly distributed conductive needles in the guide cavity 151 will contact the evenly distributed rivets on the holder. If it is found that the rivets on the holder are evenly distributed without missing rivets, the evenly distributed conductive needles 130 and the spring 131 will be lifted up together, and the lower ends of the evenly distributed conductive needles 130 will be disconnected from the conductive aluminum block 140, so that the current will not flow.

[0035] On the contrary, if there is a lack of nails, the conductive needle 130 will not be lifted up by the spring 131, and will contact and energize the conductive aluminum block 140. At this time, the equipment program will determine that it is unqualified and will be ejected.

[0036] It is determined by whether the tooling is powered on. If the equipment program shows that the station is not powered on and the current cannot pass through this tooling, the rivet holder is judged to be qualified as it does not have a missing rivet phenomenon; on the contrary, if the equipment program shows that the station is powered on and the current passes through the tooling, the rivet holder is judged to be unqualified as it has a missing rivet phenomenon, and the program setting will automatically remove the unqualified holder in the subsequent process.

[0037] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above.

[0038] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected. The scope of protection of the present invention shall be defined by the attached claims and their equivalents.
