The wheel cover assembly basically consists of the wheel cover upper reinforcement plate, suspension shock absorber reinforcement plate, seat pivot mounting reinforcement plate, seat pivot outer mounting bracket, seat cushion mounting bracket, etc.
Generally speaking, the wheel cover assembly inspection is placed according to the Petrol Car coordinate system, and the left and right wheel covers are generally not completely symmetrical. When designing, you must first figure out whether the left and right products are completely symmetrical. Since the inspection of the wheel cover assembly is complicated and the parts are relatively heavy, in order to ensure strength, the base plate is not easily deformed. The base plate for wheel cover assembly inspection generally uses a welded base plate, which can also be used if the customer has requirements. Usually, the wheel cover assembly is equipped with forklift feet under the floor. Since the base plate is placed upright, two lifting ring mounting blocks should be welded on the top of the base plate, so that after the two lifting rings are installed, the installation of the base plate is facilitated.
3. Wheel cover assembly verification positioning mode
Generally speaking, the positioning of wheel cover assembly inspection is shown in the figure, but the details should be based on the GDT drawings provided by the customer. There are two ways to position curved surfaces: patch type or bracket type. b. C positioning pin can be made in two forms: fixed and bolt. General Project B and C pins are usually positioned by two fixed circular pins. Volkswagen projects must decide whether to use tapered pins or direct positioning based on the material thickness of the product and whether there is a positioning surface under the positioning hole of the product. Generally, C is positioned on the back. It is difficult to operate as a bolt, but it is fixed. The C pin is a diamond-shaped pin. Position it on one side and test it on the other side.
