Therefore, this invention has the advantages of novel design, simple structure, ensuring that the product's flipping angle does not exceed a negative 3° during the flipping process, effectively preventing product damage, ensuring smooth rotation, ease of use, and improving product yield and quality. Attached Figure Description
[0010] The present invention will be further described below with reference to the accompanying drawings, but the embodiments in the drawings do not constitute any limitation on the present invention.
[0011] Figure 1 This is a schematic diagram of the structure of this utility model.
[0012] exist Figure 1 This includes: 1——Jig base 11——Profiling jig cavity 12 - Positioning Block; 13 - Clearance Slot 14—Anti-rotation block; 141—Anti-rotation inclined plane 15 - Hinge support block 2 - Swivel assembly 21 - Top hinge 22 - Bottom hinge 23 - Shaft 24 - Spring Detailed Implementation
[0013] The present invention will now be described in conjunction with specific embodiments.
[0014] like Figure 1As shown, a flip test fixture for a TWS box hinge assembly includes a fixture base 1 and a hinge assembly 2. The fixture base 1 has a contoured fixture cavity 11 at its upper end, and a convex positioning block 12 at the upper end of the contoured fixture cavity 11. The contoured fixture cavity 11 has a concave clearance groove 13 at its upper end, and an anti-rotation block 14 at the side end of the clearance groove 13. The hinge assembly 2 includes an upper hinge 21 and a lower hinge 22, and the upper hinge 21 and the lower hinge 22 are connected by a shaft 23 and a spring 24. The upper hinge 21 is mounted on the upper end of the contoured fixture cavity 11 and is positioned by the positioning block 12. The lower end of the lower hinge 22 is in contact with the anti-rotation block 14. The spring 24 is disposed in the clearance groove 13.
[0015] Furthermore, the upper end of the contour jig cavity 11 is provided with a hinge support block 15 arranged in a convex shape, which is used to support the upper hinge 21.
