Description

Technical Field

[0002] The upper bracket of the automobile slide rail is mainly used to connect the automobile seat and the slide rail to achieve the front and rear adjustment of the seat. The basic shape of the upper bracket of the automobile slide rail is an L-shape with large ends and a small middle. Several reinforcing ribs and reinforcing steps are arranged on the two sides of the L-shape and at the junction of the two sides, as well as several through holes of different sizes (see attached Figure 1 , 2 ). Usually, the four through holes on the short side of the L-shaped automobile slide bracket are called connecting holes, and the planes around the four connecting holes are on the same plane, which are called connecting surfaces; the two through holes on the lower position of the long side of the L-shape are called large mounting holes and small mounting holes respectively. The automobile slide bracket is formed by stamping of metal sheets, and needs to go through processes such as blanking, forming, flanging, shaping, punching, side punching, re-punching and re-side punching, and the processing difficulty is relatively large. Since the automobile slide bracket is mainly used to connect the car seat and the slide rail, in order to ensure the comfort and reliability of the front and rear adjustment of the seat, there are high technical requirements for the spatial shape and geometric dimensions of the automobile slide bracket. Among them, the higher requirement is the dimensional accuracy of the mounting hole surface, and the distance from the mounting hole surface to the reference plane (referred to as the hole surface distance) is required to meet the design requirements, and the error must be less than ±0.25mm. Among them, the mounting hole surface is the plane around the mounting hole, and the reference plane refers to the plane perpendicular to the bottom plane of the automobile slide bracket (i.e., the connecting surface) and close to the back side of the automobile slide bracket (see attached Figure 3 , 4 In the figure, a is the large mounting hole surface, b is the small mounting hole surface, c is the right-angle measuring plate, h1 is the large mounting hole surface distance, and h2 is the small mounting hole surface distance). In order to ensure product quality, the hole surface distance of the bracket on the automobile slide rail needs to be detected after the stamping is completed. The prior art method for detecting the hole surface distance of the bracket on the automobile seat slide rail adopts a right-angle measuring plate to assist in detecting the hole surface distance of the bracket on the automobile slide rail (see the attached Figure 3 ), that is, place the bottom of the upper bracket of the automobile slide rail to be tested on the horizontal plane of the right-angle measuring plate, and at the same time, place the back side of the upper bracket of the automobile slide rail close to the vertical plane of the right-angle measuring plate; then use a measuring tool such as a caliper or a depth caliper to measure the distance from the mounting hole surface to the vertical plane of the right-angle measuring plate (i.e., the reference plane), so as to determine the size of the hole surface distance of the mounting hole of the upper bracket of the automobile slide rail to be tested, and thus judge whether the hole surface distance of the mounting hole of the upper bracket of the automobile slide rail to be tested meets the design requirements.
