Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring jigs, in particular to a product fixing measuring jig. Background Art
[0002] The shape of the injection molded product is based on the size and assembly, and different draft angles are added, resulting in the product being able to be laid flat only horizontally, not vertically. According to the characteristics of the injection molded product, it is necessary to increase the draft angle on the contact surface between the product and the mold to facilitate the demoulding of the product from the mold. Since the key measurement positions of the injection molded product are on different surfaces, such as Figure 5 As shown, when using projection measuring equipment to measure key positions, it is sometimes necessary to place the product vertically to ensure that the measuring position is perpendicular to the optical axis of the projection measuring equipment. However, the addition of a draft angle on the outside of the product causes the product to be unable to be horizontal or vertical in a free state. Therefore, the projection measuring equipment cannot accurately test some key dimensions of the product, and thus cannot determine whether the product is qualified. Utility Model Content
