DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] The present utility model provides an automatic screw-locking positioning jig as shown in Figures 1-3 and includes:

[0020] A positioning base 1, one end of the positioning base 1 is rotatably connected to a positioning cover plate 3 through a rotating shaft 2. A buckle member is connected to the front end of the positioning base 1. A slot 5 is provided at the front end of the positioning cover plate 3. After the positioning cover plate 3 is flipped and closed with the positioning base 1 through the rotating shaft 2, the buckle member is engaged with the slot 5 to clamp and fix the positioning cover plate 3.

[0021] Two groups of profiling grooves 6 are provided, and both groups of profiling grooves 6 are arranged on the surface of the positioning base 1. The profiling grooves 6 can be set according to the simulation model of the shell of the product 8. A number of positioning holes 7 are annularly arranged on the surface of the positioning cover plate 3, and the positions of the positioning holes 7 match the screw holes on the surface of the product 8 placed in the profiling grooves 6.

[0022] The buckle member is an elastic clamping block 4, and the elastic clamping block 4 is engaged with the slot 5.

[0023] Two groups of height-limiting columns 9 are connected to the front end of the positioning base 1. Two groups of slots 10 are provided at the front end of the positioning cover plate 3. After the positioning cover plate 3 is flipped and closed with the positioning base 1, the two groups of height-limiting columns 9 are respectively inserted into the two groups of slots 10 to make the positioning cover plate 3 in a horizontal state after flipping. When the positioning cover plate 3 is in a horizontal state after flipping, the product 8 can be limited and fixed in the profiling grooves 6 to avoid the problem that the product 8 is placed offset and cannot be accurately aligned, resulting in the screw being misaligned and scratching the shell of the product 8.

A tail wire 12 is connected to one end of the product 8, and the tail wire 12 is placed in the tail wire positioning groove 11, so that the tail wire 12 can be correctly fixed in the tail wire positioning groove 11 to avoid displacement during processing.

[0025] This automatic screw-locking positioning jig can open the positioning base 1 by flipping the positioning cover plate 3 upwards, so that one end of the positioning cover plate 3 rotates at one end of the positioning base 1 through the rotating shaft 2. Then, two sets of products 8 to be processed are placed in the profiling grooves 6. After that, the positioning cover plate 3 is flipped back to its original position. When the positioning cover plate 3 is flipped, the card slot 5 on its surface contacts the elastic clamping block 4, causing the card slot 5 to slide along the inclined slot on the surface of the elastic clamping block 4 and squeeze the elastic clamping block 4. After the card slot 5 disengages from the extrusion of the elastic clamping block 4, the elastic clamping block 4 rebounds and engages with the card slot 5, thus clamping and fixing the positioning cover plate 3 and the positioning base 1. When the positioning cover plate 3 and the positioning base 1 are clamped, the height-limiting column 9 on the surface of the positioning base 1 will insert into the slot 10 on the surface of the positioning cover plate 3, so that the positioning cover plate 3 is in a horizontal state after flipping, limiting and fixing the product 8 in the profiling groove 6, avoiding the problem that the product 8 is placed offset and cannot be accurately aligned, resulting in the screw being misaligned and scratching the outer shell of the product 8. Then, the screw is inserted into the positioning hole 7 arranged in a ring shape on the surface of the positioning cover plate 3, and then the inserted screw is tightened into the screw hole of the product 8 by a screw machine, thus fixing the product 8 by screwing. With two profiling grooves 6, two sets of products 8 can be processed simultaneously, greatly improving the processing efficiency of the product 8;

[0026] Moreover, when opening the positioning cover plate 3, only need to push the elastic clamping block 4 towards the end close to the positioning hole 7, so that the elastic clamping block 4 disengages from the engagement with the card slot 5, and then lift the positioning cover plate 3 upwards to open the positioning base 1, take out the product 8 in the profiling groove 6 of the positioning base 1 and replace it with the next set of products 8 for processing, which is relatively convenient.
