Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy detection, in particular to an aluminum alloy brittleness detection component. Background Technique

[0002] Aluminum alloy is a kind of non-ferrous metal structural material most widely used in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. After the production of aluminum alloy is completed, it is necessary to detect the brittleness of the aluminum alloy.

[0003] After retrieval, an alloy coating brittleness detection device with the publication number of CN 216117099 U includes: a detection table and a support plate. On both sides and in the middle between the detection table and the support plate, side plates are welded. In the middle of the opposite side walls of each pair of opposite side plates, a clamping mechanism for clamping the alloy plate is arranged. On both sides of the upper end of the detection table, infrared rangefinders are fixedly connected. On both sides of the bottom end of the support plate, extrusion rods are arranged. At the upper ends of the two extrusion rods, a downward pressing mechanism is arranged. The utility model has the following advantages: by setting the infrared rangefinder, it is more accurate to detect the fracture deformation of the alloy plate through the infrared rangefinder; and the infrared rangefinder can transmit the detection data to the controller of the corresponding motor. When the middle part of the alloy plate is squeezed to have fracture deformation, the corresponding motor will stop running in time. The brittleness of the alloy plate coating can be known through the downward movement distance of the extrusion rod.

[0004] However, there are still some deficiencies in the above detection mechanism during use. There is a lack of overall protection, and debris may fly out during the alloy fracture process. At the same time, the clamping of the alloy is not stable enough, and there will be shaking during the detection process, affecting the detection result. Moreover, it is a slow and continuous downward pressure detection of the alloy, and the brittleness of the alloy under instantaneous impact cannot be detected, and the detection result is not accurate enough. Content of the Utility Model

At the top of each sub-impact column is fixedly connected a connecting screw rod, and the connecting screw rod is matched with the thread groove.

[0008] This solution can adjust the weight of the impact assembly, so as to adjust the impact force on the aluminum alloy and make the test results more accurate.

[0009] Preferred technical solution two: A fixed pulley is installed on one side of the connecting plate. The steel wire rope is arranged on the fixed pulley. The speed at which the first motor rotates and releases the steel wire rope is greater than the falling speed of the impact assembly.

Between the upper surface of the bottom plate and the lower surface of the connecting plate is fixedly connected a group of long rods. On the surface of each long rod is slidably sleeved a movable sleeve. Both of the movable sleeves are fixedly connected with the connecting sleeve.

[0012] This solution can limit the falling position of the impact assembly so that it can accurately impact the aluminum alloy.

Then, drive two pressing plates to press and fix the aluminum alloy by rotating two lead screws, making the fixing effect better and avoiding shaking during the detection process. After the aluminum alloy is fixed, close the protective door. Then, drive the winding roller to rotate by the forward rotation of the first motor, so as to release the steel wire rope, making the impact component fall under the action of gravity and impact the aluminum alloy to realize the brittleness detection of the aluminum alloy. After one impact detection is completed, drive the winding roller to wind up the steel wire rope by the reverse rotation of the first motor, and the impact component returns to its original position to perform the next detection, which is convenient and fast. At the same time, length scale lines can be set on the vertical rod. The impact force on the aluminum alloy can be calculated through the falling height of the impact component and the weight of the impact component, making the detection result more accurate. Moreover, the weight of the impact component can be increased by inserting the connecting screw on the auxiliary impact column into the internal thread groove of the main impact column for connection, and it can be adjusted according to requirements, making the detection result more accurate. When the detection mechanism is in use, the protective cover can effectively prevent aluminum alloy debris from bursting out, and at the same time, the aluminum alloy can be firmly clamped to avoid shaking during the detection process.
