[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0021] Please refer to Figures 3-4The utility model provides a technical scheme: a press -in part thrust test positioning jig, including test board, backing plate no.
[0022] The base is provided with three convex positioning strips on three continuous edges, and the side of the base without the convex positioning strip is provided with a movable positioning strip; one movable positioning strip and three convex positioning strips form a limiting frame; the test board, the backing plate no.
[0023] The specific operation steps are as follows:
[0024] 1, the press -in part that needs testing is first pressed to the test board;
[0025] 2, the backing plate no.
[0026] 3, the backing plate no.
[0027] 4, if the aperture of the backing plate no.
[0028] 5, the first step press -in good test board is placed on the backing plate no.
[0029] 6, then the assembled jig is limited by clamping the movable positioning strip;
[0030] 7, after assembly, the automatic test bench is placed to test the thrust.
[0031] The test board is provided with a plurality of press -in parts to be tested.
[0032] The backing plate no.
[0033] Through the technical scheme, the press riveting piece to be tested is first press riveted to the test plate (the plate is selected according to test requirements, the press riveting bottom hole is punched according to the size and number of the bottom hole of the press riveting piece, the position, quantity, and edge margin shape are fixed); the base is formed by wood milling, the base via hole (via hole three) on the base is consistent with the position, quantity, and edge margin shape of the hole on the press riveting test plate, the base three edges are designed as positioning bosses, and one edge is left as a notch to facilitate material taking and placing; the first gasket plate is punched or laser cut from stainless steel (the plate thickness is 3.0 mm), the size of the via hole one on the gasket plate is determined according to the size of the press riveting piece to be tested and the via hole required by the PEM, and the via hole on the gasket plate is consistent with the position, quantity, and edge margin shape of the bottom hole on the press riveting test plate; the second gasket plate is punched or laser cut from stainless steel (the plate thickness is 3.0 mm), the size of the via hole two on the gasket plate is larger than that of the via hole one on the first gasket plate and smaller than that of the base via hole (via hole three), and the via hole two is consistent with the position, quantity, and edge margin shape of the bottom hole on the press riveting test plate.
[0034] The function of the second gasket plate is to prevent the via hole one on the first gasket plate from having a large difference in hole diameter with the base via hole (via hole three), so as to avoid the via hole one on the first gasket plate directly bearing on the base via hole and causing deformation of the first gasket plate.
