Description

Technical Field

[0001] This utility model belongs to the field of aluminum ingot casting technology, specifically a device for testing the hardness of aluminum ingots after casting. Background Technology

[0002] Aluminum ingots are an industrial raw material, which should be called "aluminum ingots for remelting" according to national standards. They are produced by electrolysis of alumina-cryolite. Aluminum ingot casting is the process of injecting liquid aluminum into a mold and cooling and solidifying it into a solid aluminum ingot. After casting, the hardness of the aluminum ingot needs to be tested by a hardness testing device to see if it meets the standard.

[0003] In existing technology, an aluminum plate hardness testing mechanism with application number CN202021574843.X uses a fixing mechanism to clamp and fix the aluminum plate, and uses two hydraulic cylinders to drive a moving stage to fully compress and contact the aluminum plate substrate with the pressure block. The pressure block, in conjunction with a connecting plate, transmits the pressure to a pressure sensor for data detection. However, when performing multi-sided hardness testing on aluminum ingots, after testing one side, the aluminum ingot needs to be removed from the fixing mechanism, manually flipped, and then placed back into the fixing mechanism for clamping and fixing. This flipping and testing process involves many steps and has low work efficiency. Therefore, we provide a hardness testing device for aluminum ingots after casting. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that when performing multi-face hardness testing on aluminum ingots, after testing one side of the ingot, it is necessary to remove the ingot from the fixing mechanism, manually flip the ingot, and then put it back into the fixing mechanism for clamping and fixing. This involves many flipping and testing steps and low work efficiency. Therefore, a hardness testing device for aluminum ingots after casting is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a device for testing the hardness of aluminum ingots after casting, comprising:

[0006] The base is fixedly installed on the top plate at the upper end of the base.

[0007] A rotation limiting component is installed on the left and right sides of the upper end of the base and is used to drive the aluminum ingot to rotate for detection.

[0008] A testing component, installed at the lower end of the top plate, is used to test the hardness of aluminum ingots;

[0009] An aluminum ingot limiting component is installed at the middle of the upper end of the base and is used to limit and lock the aluminum ingot.

[0010] Preferably, the rotation limiting assembly includes: a fixed plate fixedly installed on the left and right sides of the upper end of the base; a first lead screw is rotatably connected inside the fixed plate; a slider is rotatably connected outside the first lead screw; a turntable is rotatably connected to the side of the slider near the central axis; a first hydraulic rod is fixedly installed in the middle of the turntable near the central axis; a push plate is fixedly installed on the side of the first hydraulic rod near the central axis; a sleeve is fixedly installed at the front and rear ends of the turntable near the central axis; a support column is slidably connected inside the sleeve; and one side of the support column is welded to the push plate.

[0011] Preferably, the detection assembly includes: a slide rail fixedly installed at the lower end of the top plate; a slide table slidably connected to the outer side of the slide rail; a stabilizing plate fixedly installed on the front and rear sides of the lower end of the slide table; a second lead screw rotatably connected between the middle of the stabilizing plates; a movable platform rotatably connected to the outer side of the second lead screw; a second hydraulic rod fixedly installed at the lower end of the movable platform; a detection head fixedly installed at the lower end of the second hydraulic rod; and slide rods fixedly installed on the left and right sides between the stabilizing plates.

[0012] Preferably, the aluminum ingot limiting assembly includes: a sliding groove formed in the middle of the upper end of the base, a double-ended lead screw rotatably connected inside the sliding groove, a moving block rotatably connected to the outside of the double-ended lead screw, a clamping plate fixedly installed on the upper end of the moving block, and a rubber pad adhered to the side of the clamping plate near the central axis.

[0013] The beneficial effects of this utility model are:

[0014] The rotation limiting component of this utility model drives the slider to slide upward through the first lead screw, and at the same time activates the electric motor inside the slider to drive the turntable to rotate, thereby driving the aluminum ingot to rotate and realize the flipping of the aluminum ingot, which facilitates the surface inspection of the aluminum ingot and improves the accuracy of the aluminum ingot hardness test results. By activating the first hydraulic rod on the turntable, the push plate is driven to move closer to the aluminum ingot and fit, realizing the left and right side limiting of the aluminum ingot and improving the stability of the aluminum ingot hardness test.

[0015] The detection component of this invention uses a second lead screw and a slide rail to drive the detection head to slide, thereby adjusting the position of the detection head. This facilitates more comprehensive hardness testing of the aluminum ingot. At the same time, the double-headed lead screw in the aluminum ingot limiting component works with the clamping plate to limit the aluminum ingot in front and behind, preventing the aluminum ingot from sliding during hardness testing and affecting the accuracy of the test results.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Specific implementation examples are given below.

[0029] Example 1:

[0030] Please see Figures 1 to 5 This utility model provides a device for testing the hardness of aluminum ingots after casting, comprising:

[0031] Base 1, top plate 2 fixedly installed on the upper end of base 1;

[0032] Rotation limit component 3 is installed on the left and right sides of the upper end of the base 1 and is used to drive the aluminum ingot to rotate for detection;

[0033] Detection component 4 is installed at the lower end of the top plate 2 and is used to test the hardness of aluminum ingots;

[0034] Aluminum ingot limiting component 5 is installed at the upper middle part of the base 1 and is used to limit and lock the aluminum ingot.

[0035] In this embodiment, after the aluminum ingot is placed on the base 1, the aluminum ingot limiting component 5 is activated to limit and lock the front and rear sides of the aluminum ingot, so as to prevent the aluminum ingot from moving during the test and affecting the test results. Then, the rotation limiting component 3 is activated to limit the left and right sides of the aluminum ingot, further improving the stability of the aluminum ingot during the test. Then, the test component 4 is activated to perform hardness test on the aluminum ingot. After one side of the aluminum ingot is tested, the rotation limiting component 3 is activated to drive the aluminum ingot to flip, thereby performing the test on the flipped aluminum ingot and improving the accuracy of the hardness test results.

[0036] Example 2:

[0037] Based on Embodiment 1, a rotation limiting component 3 is further disclosed.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the rotation limiting assembly 3 includes: a fixed plate 301 fixedly installed on the left and right sides of the upper end of the base 1; a first lead screw 302 rotatably connected inside the fixed plate 301; a slider 303 rotatably connected outside the first lead screw 302; a turntable 304 rotatably connected to the side of the slider 303 near the central axis; a first hydraulic rod 305 fixedly installed in the middle of the turntable 304 near the central axis; a push plate 306 fixedly installed on the side of the first hydraulic rod 305 near the central axis; and sleeves 307 fixedly installed at the front and rear ends of the turntable 304 near the central axis. A support column 308 is slidably connected inside the sleeve 307, and one side of the support column 308 is welded to the push plate 306.

[0039] In this embodiment, the aluminum ingot is placed on the base 1 and the aluminum ingot limiting component 5 is activated to initially limit the aluminum ingot. Then, the first hydraulic rod 305 on the turntable 304 is activated, driving the push plate 306 to approach the aluminum ingot and fit against it, thus limiting the left and right sides of the aluminum ingot. When the push plate 306 slides, the support column 308 also slides within the sleeve 307, improving the stability of the push plate 306 during sliding. After one side of the aluminum ingot is inspected, the aluminum ingot limiting component 5 is activated to release the limiting lock on the aluminum ingot. Then, the motor on the fixed plate 301 is activated, driving the first lead screw 302 to rotate. The rotation of the first lead screw 302 drives the slider 303. The aluminum ingot slides upward within the fixed plate 301, thereby causing the aluminum ingot held between the turntable 304 and the push plate 306 to slide upward. When the aluminum ingot slides to a certain height, the motor inside the slider 303 is activated, thereby causing the turntable 304 to rotate. The rotation of the turntable 304 causes the first hydraulic rod 305 and the push plate 306 to rotate, thereby causing the aluminum ingot to rotate and achieve the flipping of the aluminum ingot. Then, the motor is activated to drive the first lead screw 302 to rotate, causing the slider 303 to slide downward, so that the aluminum ingot is in contact with the base 1, and the aluminum ingot limiting assembly 5 is restarted to limit the aluminum ingot, which facilitates multi-face inspection of the aluminum ingot and improves the accuracy of the aluminum ingot hardness test results.

[0040] Example 3:

[0041] Based on Example 1, the detection component 4 is further disclosed.

[0042] like Figure 1 and Figure 2 As shown, the detection component 4 includes: a slide rail 401 fixedly installed at the lower end of the top plate 2; a slide table 402 slidably connected to the outside of the slide rail 401; a stabilizing plate 403 fixedly installed on the front and rear sides of the lower end of the slide table 402; a second lead screw 404 rotatably connected between the middle of the stabilizing plates 403; a movable table 405 rotatably connected to the outside of the second lead screw 404; a second hydraulic rod 406 fixedly installed at the lower end of the movable table 405; a detection head 407 fixedly installed at the lower end of the second hydraulic rod 406; and slide rods 408 fixedly installed on the left and right sides between the stabilizing plates 403.

[0043] In this embodiment, after the aluminum ingot is locked by the aluminum ingot limiting component 5 and the rotation limiting component 3, the second hydraulic rod 406 is activated, causing the detection head 407 to slide down and contact the aluminum ingot. The detection head 407 is a Rockwell hardness tester. By contacting the aluminum ingot with the detection head, the hardness of the aluminum ingot is detected. When it is necessary to change the detection position of the aluminum ingot, the slide rail 401 is activated, causing the slide table 402 to slide on the slide rail 401. At the same time, the motor on the stabilizing plate 403 is activated, causing the second lead screw 404 to rotate, thereby causing the movable table 405 to slide on the slide table 402. When the movable table 405 slides on the slide table 402, it also slides synchronously on the slide rod 408, improving the stability of the movable table 405 during sliding. This causes the second hydraulic rod 406 to slide with the detection head 407, realizing the adjustment of the position of the detection head 407, which facilitates a more comprehensive hardness test of the aluminum ingot.

[0044] Example 4:

[0045] Based on Example 1, the aluminum ingot limiting component 5 is further disclosed.

[0046] like Figure 1 and Figure 5 As shown, preferably, the aluminum ingot limiting component 5 includes: a slide groove 501 opened in the middle of the upper end of the base 1, a double-ended lead screw 502 rotatably connected inside the slide groove 501, a moving block 503 rotatably connected to the outside of the double-ended lead screw 502, a clamping plate 504 fixedly installed on the upper end of the moving block 503, and a rubber pad 505 glued to the side of the clamping plate 504 near the central axis.

[0047] In this embodiment, after the aluminum ingot is placed on the base 1, the motor is started to drive the double-headed lead screw 502 to rotate, which drives the moving block 503 to slide in the slide groove 501, thereby driving the clamping plate 504 to slide, so that the clamping plate 504 gradually fits into the aluminum ingot, realizing the limiting and locking of the aluminum ingot, avoiding the aluminum ingot sliding during hardness testing from affecting the accuracy of the test results. The design of the rubber pad 505 improves the tightness of the fit between the clamping plate 504 and the aluminum ingot, thereby improving the clamping effect of the aluminum ingot.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
