[0016] The embodiment provides a punch die concentricity gauge, as shown in Figure 1 、 Figure 2 , including the slot 11 that is transversely penetrated in the gauge main body 10, the gauge main body 10 is cuboid as a whole, and the punch slot 20 and the die slot 30 are symmetrically set up in the upper top surface and the lower top surface of the gauge main body 10, and the punch slot 20 and the die slot 30 are concentrically arranged and are communicated through the cuboid slot 11, wherein the upper top surface of the gauge main body 10 is also symmetrically provided with two adjusting grooves 21, and the adjusting grooves 21 are all slidably connected with the pressure pieces.

[0017] As shown in Figure 3 , the pressure piece in the embodiment is specifically H-shaped steel 22, and in other embodiments, it can also be a long strip structure suitable for the depth and width of the adjusting groove 21, and the bolt 23 is threadedly connected on each H-shaped steel 22, and the bolt 23 locks the H-shaped steel 22 when fastened, and in the embodiment, the bolt 23 moves downward and is directed to the bottom of the adjusting groove 21 when fastened, and in other embodiments, if the bolt 23 is designed transversely, the bolt 23 can also be directed to the side wall of the adjusting groove 21 when fastened;Both adjusting grooves 21 are through grooves, and the end close to each other extends to the punch slot 20, and the end away from each other extends to the outside of the gauge main body 10.

[0018] It should be noted that the adjusting groove 21 in the application can also be a I-shaped or inverted T-shaped cross section, so that the H-shaped steel 22 can be slidably connected in the adjusting groove 21 in the horizontal direction.

[0019] The punch die concentricity gauge in the application can place the punch 40 and the die 50 in the gauge main body 10 for size detection when in use. The specific process can be referred to Figure 2First, place the die 50 into the die groove 30 of the fixture body 10 from one side of the slot 11. Then, place the punch 40 directly into the punch groove 20 from above the fixture body 10. Figure 4 As shown, the punch 40 is positioned above the die 50 at this time, allowing the punch 40 or the die 50 to be rotated separately to check and determine the gap between them. It can be understood that when the punch 40 needs to be positioned, the two H-beams 22 can be slid against each other to abut the sides of the punch 40, and then the bolt 23 can be rotated. The bottom of the bolt 23 contacts the bottom surface of the adjusting groove 21, positioning the H-beams 22 and fixing the punch 40 between the H-beams 22.

[0020] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
