Description

Technical Field

[0001] The utility model relates to a hole position detection technology for an automobile seat pan installation hole, in particular to a hole position detection tool for an automobile seat pan installation hole. Background Art

[0002] In order to improve the comfort and durability of car seats, a seat basin is used to replace the steel mesh of traditional seats, so as to increase the strength of the car seat cushion and improve the riding comfort. The seat basin is a sheet metal stamping structure, and its appearance is similar to the seat cushion of the seat, like a basin; therefore, it is called a seat basin. The seat basin is made of metal sheet after more than 10 stamping processes, and contains several complex structures or shapes such as step holes, flanges, hems, folded tongues and side through holes. The entire seat basin is stamped with more than 40 through holes distributed on the surfaces in different spaces, which are used to install the seat basin on the car seat frame, or to install accessory components on the seat basin, such as; slide rails and handles, etc. (see attached Figure 1 , 2 ). Usually, the through holes on the seat basin used to install the seat basin on the car seat frame, or the through holes on the seat basin for installing accessory parts are collectively referred to as mounting holes. After the seat basin is stamped, it is necessary to detect the hole position of each mounting hole. The hole position refers to the spatial position of each mounting hole, and the hole position detection refers to the detection of whether the position of each mounting hole meets the design requirements. Since there are a large number of seat basin mounting holes and they are distributed on the surfaces of different spaces, it is difficult to detect their spatial positions using traditional gauges; especially for the hole positions of some mounting holes, due to the limited detection space, traditional gauges are almost impossible to detect; or, the detection results are not accurate enough, especially for some mounting holes with angle requirements.
