[0032] Combination Figures 1 to 6 As shown, the present invention provides a gauge for measuring the rebound of a stamped part, comprising a fixed plate 1, a connecting plate 2, and a contact plate 3.

[0033] Combination Figures 1 to 6 As shown, the fixing plate 1 is fan-shaped, and an arc-shaped sliding groove 11 is formed on the fixing plate 1. Each of the two fan-shaped sides of the fixing plate 1 has a sliding groove 11. The connecting plate 2 is embedded and slidably assembled within the sliding groove 11. A scale is provided on both the fixing plate 1 and the connecting plate 2 to mark their positional relationship. A fastening screw 13 is threaded onto the fixing plate 1, and the fastening screw 13 abuts against the connecting plate 2. The fastening screw 13 fixes the positional relationship between the fixing plate 1 and the connecting plate 2, and also limits the movement of the connecting plate 2. Figure 6 The fastening screw 13 shown can prevent the connecting plate 2 from sliding out of the groove 11.

[0034] The position of the adjustable slide groove 11 is on the two sides of the fixed plate 1, that is, the fixed plate 1 has a slide groove 11 on each of the two flat sides, and the connecting plate 2 is embedded and slidably assembled in the slide groove 11; at this time, observation ports can be opened on the fixed plate 1 corresponding to the two connecting plates 2 shown, so as to facilitate the viewing of the scale.

[0035] The number of connecting plates 2 is two, and the two connecting plates 2 are slidably assembled in the slide groove 11 from both sides. The two connecting plates 2 slide in the slide groove 11, which causes the spatial angle between the bottom surfaces of the two contact plates 3 to change. The connecting plates 2 are integrally formed with reinforcing ribs 21, which improves the structural strength and facilitates the assembly of the connecting plates 2 in an embedded manner.

[0036] The number of contact plates 3 is two, and the top surfaces of the two contact plates 3 are respectively fixedly connected to the two connecting plates 2. A first magnet 33 is embedded and fixedly mounted on the contact plate 3, which facilitates the contact plate 3 to adhere to the surface of the metal part being tested. At the same time, a second magnet 12 can be fixedly mounted on one side of the fixing plate 1. The connecting plate 2 can slide on the fixing plate 1, so that the second magnet 12 and the first magnet 33 can attract each other, which facilitates fixing the fixing plate 1 and the connecting plate 2 at the position corresponding to the 0 mark, improving the user experience.

[0037] In some embodiments, combined with Figure 5 As shown, a recessed groove 31 is integrally formed on the bottom surface of the contact plate 3. An extension plate 32 is slidably assembled in the recessed groove 31. The surface of the extension plate 32 is flush with the bottom surface of the contact plate 3. The extension plate 32 can be slid so that one end of it extends out of the contact plate 3. The extension plate 32 enhances the contact capability of the contact plate 3 and improves the overall adaptability to stamped parts of different sizes.

[0038] In this embodiment, the fixing plate 1, the connecting plate 2, and the contact plate 3 are all copper metal parts, and the process of embedding graphite reduces wear and improves service life; at the same time, the fixing plate 1 and the connecting plate 2 are integrally formed with hollow grooves 4, which reduces their own weight and improves the user experience.

[0039] Working process: The bottom surfaces of the two contact plates 3 are placed against the surface being measured. The sum of the corresponding scales of the two connecting plates 2 is the angle between the surfaces being measured. One of the scales corresponding to one of the connecting plates 2 can be selected as 0 or other fixed integer values ​​to reduce the amount of calculation required for summation and improve the user experience.

[0040] Alternatively, the two connecting plates 2 can be fixed in corresponding positions by fastening screws 13, and one contact plate 3 can be pressed against the surface being measured. The other contact plate 3 can be compared to see if it fits the other surface being measured, thereby determining whether the workpiece being measured meets the standard.

[0041] The technical solution of this utility model is to slide the fixed plate and the connecting plate together through an arc-shaped groove, and use the contact plate to abut the measured surface so that the measured angle information can be intuitively reflected in the positional relationship between the fixed plate and the connecting plate. The angle change process between the two contact plates is associated with the sliding process between the fixed plate and the connecting plate. The measurement process is simple and fast, and it is suitable for the preliminary measurement of stamped workpieces.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
