[0002] Many existing test equipment and molds do not have centering devices and functions, such as some sheet metal forming test machines and drawing molds. This results in only approximate centering during testing and processing, which takes a lot of time and cannot be accurately aligned, ultimately leading to test errors and failed products in forming tests or processing. Utility Model Content

[0003] In view of the above situation, in order to overcome the existing technical defects, the utility model provides an auxiliary centering device, which can act on metal sheet forming test equipment and some molds to achieve centering assistance, helping operators to complete centering quickly and accurately.

[0004] The technical solution adopted by the utility model is as follows: The utility model provides an auxiliary centering device for a metal sheet forming testing machine, comprising a rotating cover, a block, a main body, a short spring, a handle, a connecting mechanism, a limiting mechanism, a short extension rod, a long spring, and a long extension rod. The rotating cover is arranged on the main body, and four slide grooves are arranged on the rotating cover. The main body is provided with four evenly distributed square holes. The short extension rod and the long extension rod are arranged in pairs on the main body through the square holes. The front end of the long extension rod has a hook, and the ends of the short extension rod and the long extension rod are provided with a baffle. The short extension rod and the long extension rod are provided with a vertical rod, and the vertical rod is located in the slide groove on the rotating cover. The limiting mechanism is located on the main body, and a connecting mechanism is provided on the limiting mechanism. A pair of hooks are provided on the connecting mechanism, and a handle is provided on the connecting mechanism. A groove is provided on the top of the handle for installing a micro laser. The short spring is located between the main body and the limiting mechanism, and the long spring is located between the connecting mechanism and the short extension rod and the long extension rod.

[0005] Furthermore, the four slide grooves on the rotating cover are evenly distributed around the circumference and are equal in size, so that the four extension rods can be extended synchronously to ensure the centering accuracy. There is a cylindrical protrusion in the middle of the rotating cover, and there are striped protrusions outside the cylindrical protrusion to increase friction and facilitate hand-held rotation. The rotation of the slide groove on the rotating cover will drive the four vertical rods in the slide groove to move, thereby driving the short extension rod and the long extension rod to extend in and out.

[0006] Furthermore, the short extension rod and the long extension rod are fixedly connected with the stoppers at their ends by screws.

[0007] Furthermore, the outer surface of the baffle has striped protrusions.

[0008] Furthermore, the limiting mechanism and the connecting mechanism are connected by thread.

[0009] Furthermore, the handle and the connecting mechanism are connected by thread.

[0010] Furthermore, the top diameter of the handle is larger than the diameter of the cylindrical protrusion on the rotating cover, thereby limiting the position of the rotating cover.

[0011] The beneficial effects achieved by the utility model using the above-mentioned structure are as follows: the auxiliary centering device of a metal sheet forming testing machine provided by the present scheme drives the short extension rod and the long extension rod to extend outward through a spring, can adapt to a certain range of installation hole diameters, and be fixed in the installation position; the rotating cover plate can be rotated manually, and the four extension rods can be synchronously retracted through the slide groove and quickly removed; secondly, the rotating mechanism and the long extension mechanism are provided with hooks, which can fix the long extension rod after the long extension rod is manually retracted, and the short extension rod can be fixed by relying on the slide groove on the rotating cover plate; the spring between the limiting mechanism and the connecting mechanism pushes the connecting mechanism upward, ensuring that the hooks between the connecting mechanism and the long extension rod are stuck to each other.
