[0024] As Figures 1 to 3 shown, the utility model relates to a positioning jig for special-shaped magnetic core heat treatment, which comprises a positioning base 1, positioning side plates 2 arranged on both sides and a positioning bottom plate 11.
[0025] The positioning base 1 comprises a horizontally arranged positioning bottom plate 11 and a positioning frame column 12 vertically extending and arranged on the upper side of the center of the positioning bottom plate 11; two groups of plug-in interfaces 13 are symmetrically arranged on both sides of the positioning frame column 12 corresponding to the positioning bottom plate 11. The positioning side plate 2 is straightly and extendingly arranged; two positioning side plates 2 are arranged as a group, and the two positioning side plates 2 in the group are correspondingly inserted into the corresponding plug-in interfaces 13 on both sides, so that the two positioning side plates 2 are vertically extendingly arranged; the lower side of the positioning side plate 2 is plug-in adaptively connected with the plug-in interface 13. The positioning top plate 3 is centrally provided with a frame column interface 31, and a plurality of side plate interfaces 32 are arranged on both sides of the frame column interface 31; the frame column interface 31 is positionally and adaptively connected with the positioning frame column 12, each group of side plate interfaces 32 is positionally adapted with each group of plug-in interfaces 13; and the upper side of the positioning side plate 2 is plug-in adaptively connected with the side plate interface 32.
[0026] When clamping the special-shaped magnetic core, according to the size of the magnetic core, the corresponding type of positioning base 1 is selected, the positioning frame column 12 on the positioning base 1 can form support on the inner side of the special-shaped magnetic core on both sides, and the outer diameter of the magnetic core is adapted, the two positioning side plates 2 of the specified size clamp the outer side position of the special-shaped magnetic core supported on the inner side on both sides, and the inner side and outer side positioning and clamping application requirements of the special-shaped magnetic core are met. In the application process, a plurality of same magnetic cores are connected in the vertical direction of the positioning frame column 12, and the simultaneous positioning and clamping application requirements of the plurality of magnetic cores can be met.
[0027] In this embodiment, for the runway type or rectangular shape, square shape of the special-shaped magnetic core 4, the positioning frame column 12 in the positioning base 1 is arranged in a rectangular column shape, and in the positioning jig of this embodiment, the short side of the positioning frame column 12 is selected to position and support the inner side of the magnetic core 4 on both sides.
[0028] The two insertion interfaces 13 are symmetrically positioned at the short sides of the two ends of the positioning frame post 12. Insertion ends 21 are provided on the lower side of the two positioning side plates 2. The width of the positioning side plate 2 is greater than that of the insertion interface 13, and the width of the insertion end 21 is adapted to fit the insertion interface 13. An inclined guide slope 22 is formed on the insertion end 21. The thickness of the positioning side plate 2 and the insertion end 21 are the same, and the transition between the side surface of the positioning side plate 2 and the side surface of the insertion end 21 is smooth.
