[ detailed description ] embodiments

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to 9, a universal shaping jig includes a base 10, an upper press plate 20, a plurality of press blocks 30, and a locking assembly 40. Wherein, a supporting and positioning structure 50 for hanging the product 100 is arranged on the base 10; the upper pressure plate 20 is horizontally arranged above the base 10, and one end of the upper pressure plate is rotatably connected with the base 10 through a rotating shaft 11; each pressing block 30 is arranged on the upper pressing plate 20; the pressing head end of each pressing block 30 is positioned between the upper pressing plate 20 and the base 10 and can move towards or away from the base 10 relative to the upper pressing plate 20; the locking assembly 40 is capable of locking the upper platen 20 to the base 10.

Specifically, in the universal-type shaping jig, the structure of the base 10 is shown in fig. 4. The supporting and positioning structure 50 includes a plurality of spacers 51, a gap 52 is opened on the top surface of each spacer 51, and a positioning groove is formed between each gap 52 for positioning and placing the product 100 to be reshaped and suspending the central portion of the product 100 to be reshaped.

In order to position the products 100 with different specifications and sizes, a plurality of cushion blocks 51 can be arranged, wherein one cushion block 51 is fixedly connected with the base 10, and the rest cushion blocks 51 can move relative to the base 10. The number and the adjusting direction of the cushion blocks 51 can be set correspondingly according to actual requirements. In the present invention, four spacers 51 are provided, a first spacer 51 is fixedly connected to the base 10, a second spacer 51 and a third spacer 51 are movably adjusted in the X-axis direction and the Y-axis direction, respectively, and a fourth spacer 51 is movably adjusted in a direction inclined with respect to the X-axis and the Y-axis.

As shown in fig. 5, a plurality of adjusting holes 21 are formed on the upper press plate 20, and one press block 30 is located in one adjusting hole 21. Wherein, the outer side of each pressing block 30 is provided with an external thread; two ends of the adjusting hole 21 are respectively provided with a nut, and the pressing block 30 positioned in the adjusting hole 21 is in threaded connection with the two nuts. Furthermore, a part of the adjusting holes 21 on the upper platen 20 are opened along the X-axis direction, and the other part thereof is opened along the Y-axis direction.
