Technical Field

[0001] This utility model relates to the technical field of stamping part testing and clamping equipment, specifically a fixture for testing anti-deformation stamping parts. Background Technology

[0002] In modern manufacturing, stamped parts are widely used in many fields such as automobiles, aerospace, and electronics. With the continuous advancement of industrial technology, the requirements for the quality and performance of stamped parts are becoming increasingly stringent. Among them, the resistance to deformation has become one of the important indicators for measuring the quality of stamped parts. However, traditional stamped part testing fixtures have certain limitations in design, and cannot fix and clamp stamped parts of different sizes, resulting in poor adaptability. At the same time, when stamped parts are subjected to deformation testing, they may be squeezed, deformed, or even broken, which can easily cause debris to fly and injure workers. To solve the above problems, a fixture for testing deformation-resistant stamped parts is needed.

[0003] An existing fixture for testing anti-deformation stampings cannot meet the requirements for fixing and clamping stampings of different sizes and cannot provide safety protection during operation. Therefore, there is an urgent need for a new fixture for testing anti-deformation stampings. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a fixture for testing anti-deformation stampings, so as to solve the problem that existing fixtures for testing anti-deformation stampings cannot meet the requirements for fixing and clamping stampings of different sizes and cannot provide safety protection when in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for testing anti-deformation stamped parts, comprising a base, a sliding groove formed on the inner wall of the base, a clamping plate installed on the top of the base, a fixed shaft installed on the bottom of the clamping plate, a fixed sleeve installed on the outer wall of the fixed shaft, a gasket installed on the bottom of the fixed sleeve, a pressure rod installed on the inner wall of the clamping plate, a limit sleeve installed on the outer wall of the pressure rod, an anti-slip sleeve installed on the bottom of the pressure rod, a stamped part installed on the inner wall of the clamping plate, a locking rod installed on the side wall of the base, a protective plate installed on the outer wall of the base, and a locking groove formed on the inner wall of the protective plate.

[0006] Preferably, the clamping plate is L-shaped, and the fixing shaft is threadedly connected to the clamping plate.

[0007] Preferably, the fixed shaft is engaged with the base, and the pressure rod is threadedly connected to the clamping plate.

[0008] Preferably, the anti-slip sleeve is sleeved with the pressure rod, and the anti-slip sleeve is tightly fitted with the stamped part.

[0009] Preferably, the clamps are evenly distributed around the central axis of the base sidewall, and the protective plates are symmetrically arranged around the central axis of the base.

[0010] Preferably, the slot is designed in the shape of a water droplet, and the slot is engaged with the lever.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of a sliding groove, clamping plate, fixed shaft, fixed sleeve, gasket, pressure rod, limiting sleeve, anti-slip sleeve and stamping part, adjusts the position of the clamping plate along the sliding groove according to the required length of the stamping part to be tested. Then, the fixed sleeve and fixed shaft are rotated to tighten the threads, thereby fixing the position of the clamping plate. Then, the stamping part is inserted into the clamping plate and the pressure rod is rotated to make the threads of the pressure rod press downward to fix the stamping part. The combined use of the sliding groove, clamping plate, fixed shaft and fixed sleeve can fix stamping parts of any length, making it more versatile.

[0013] 2. This utility model, through the setting of the clamping rod, protective plate and clamping groove, addresses the safety hazards that may occur when stamped parts are subjected to deformation and breakage during deformation resistance testing, resulting in flying fragments. The protective plate is fixed by engaging with the clamping rod through the clamping groove, thus shielding the pressure-bearing area of ​​the stamped part and improving the safety of the stamped part testing process.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figure 1-4 A fixture for testing deformation-resistant stamped parts includes a base 1, a groove 2 on the inner wall of the base 1, a clamping plate 3 mounted on the top of the base 1, a fixing shaft 4 mounted on the bottom of the clamping plate 3, a fixing sleeve 5 mounted on the outer wall of the fixing shaft 4, a gasket 6 mounted on the bottom of the fixing sleeve 5, a pressure rod 7 mounted on the inner wall of the clamping plate 3, a limit sleeve 8 mounted on the outer wall of the pressure rod 7, an anti-slip sleeve 9 mounted on the bottom of the pressure rod 7, and a stamped part 10 mounted on the inner wall of the clamping plate 3. The clamping plate 3 is L-shaped, and the fixing shaft 4 is threadedly connected to the clamping plate 3 and engaged with the base 1. The pressure rod 7 is threadedly connected to the clamping plate 3, and the anti-slip sleeve 9 is sleeved with the pressure rod 7 and the stamped part. The 10 parts fit together tightly. Through the set slide groove 2, clamping plate 3, fixed shaft 4, fixed sleeve 5, gasket 6, pressure rod 7, limit sleeve 8, anti-slip sleeve 9 and stamping part 10, according to the required length of the stamping part 10 to be tested, the clamping plate 3 is adjusted along the slide groove 2, and then the fixed sleeve 5 is rotated to tighten the threads with the fixed shaft 4, thereby fixing the position of the clamping plate 3. Then the stamping part 10 is inserted into the clamping plate 3, and the pressure rod 7 is rotated to make the threads of the pressure rod 7 press downward to fix the stamping part 10. The cooperation of slide groove 2, clamping plate 3, fixed shaft 4 and fixed sleeve 5 can fix stamping parts 10 of any length, making it more versatile.

[0022] Please see Figure 1-4 A fixture for testing deformation-resistant stamped parts includes a base 1 with clamping rods 11 mounted on its side wall and a protective plate 12 mounted on its outer wall. The inner wall of the protective plate 12 has a slot 13.
