Technical Field

[0001] The utility model relates to the technical field of casting compressive strength detection, in particular to a magnesium-aluminum alloy top cover casting compressive strength detection device. Background Art

[0002] Castings refer to equipment components made of pure aluminum or aluminum alloys by casting. Generally, a sand mold or metal mold is used to pour the heated liquid aluminum or aluminum alloy into the mold cavity. The parts of various shapes and sizes obtained are usually called die castings. Die castings made of magnesium-aluminum alloy are also called magnesium-aluminum alloy castings.

[0003] Magnesium-aluminum alloy can be used to prepare top cover castings due to its advantages of low density and high strength. Compared with other materials, it is lighter. Top cover castings need to be pressed with high strength when used, so the top cover castings need to be tested for compressive strength during production. However, in the existing technology, the top cover castings can only be tested one by one sequentially, resulting in low testing efficiency. In addition, if the test fails, it may cause fragments to fly on the top of the top cover casting, which poses certain safety hazards.

[0004] Therefore, it is necessary to provide a magnesium-aluminum alloy roof casting compressive strength detection device to solve the above technical problems. Utility Model Content

[0005] The purpose of the present invention is to provide a device for detecting the compressive strength of a magnesium-aluminum alloy roof casting to solve the problems existing in the above-mentioned background technology. The technical solution of the present invention is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for detecting the compressive strength of a magnesium-aluminum alloy top cover casting, comprising a base plate, a support plate being equidistantly installed on the top of the base plate, a groove being provided in the top center of the base plate, a clamping mechanism being equidistantly installed inside the groove, a baffle mechanism being equidistantly provided on the top of the base plate, a support seat being installed on the top of the base plate, and a detection mechanism being equidistantly installed on the top of the support seat.

[0009] Preferably, the baffle mechanism also includes two slots equidistantly opened at the front and rear ends of the top of the base plate and located on both sides of the support plate, the extension direction of the two slots is parallel to the extension direction of the groove, and the inside of the two slots is connected to the side away from the support plate with the second electric telescopic rod, the other end of the two electric telescopic rods is connected to the second movable block, and the top of the two movable block is connected to the second baffle.

[0010] Preferably, a through hole for accommodating the movement of the arc block is opened on one side of the second baffle.

[0011] Preferably, the detection mechanism includes a hydraulic rod equidistantly installed on the top of the support seat, the telescopic end of the hydraulic rod passes through the support seat and is connected to a pressure sensor, the bottom of the pressure sensor is connected to a pressure plate, and the bottom of the pressure plate is equidistantly installed with a detection head.

[0012] Anything not described in detail in the present invention is well known to those skilled in the art.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model controls the rotation of the rotating rod, thereby controlling the two threaded seats to move toward or away from each other through the bidirectional thread, thereby clamping and fixing the top cover placed on the top of the support plate, and during the clamping process, the top cover tends to the center position of the support plate, and can clamp top cover castings of the same width at the same time, making it convenient to perform compression resistance testing on multiple groups of top cover castings at the same time, thereby improving the testing efficiency;

[0015] After the top cover casting is clamped, the utility model drives the movable block 1 to move toward the support plate by extending the first electric telescopic rod, so that the first baffle can be attached to the front and rear ends of the support plate. The second electric telescopic rod can be extended to drive the movable block 2 to move toward the support plate, so that the second baffle can be attached to the front and rear ends of the support plate, and cooperate with the first baffle to seal the outer side of the support plate. When the top cover casting is subjected to a pressure test and the top cover casting fails, when debris splashes in the top area of ​​the top cover casting, the debris can be blocked on the top of the support plate, thereby avoiding the safety hazard caused by the splashing of debris.

[0016] When the utility model performs a compressive strength test on the top cover casting, the hydraulic rod is controlled to extend so that the detection head just fits against the top of the top cover casting. At this time, the value of the pressure sensor is zero, and multiple points of the top of the top cover casting can be detected at the same time, which has a better effect. Then the hydraulic rod drives the detection head to squeeze the top cover casting until the pressure sensor reaches a preset pressure value to ensure that the top cover casting is qualified. After the pressure sensor reaches the preset pressure value, the pressure value is maintained for a period of time. If the top cover casting is not damaged, it can be said to be qualified. If damage occurs, it can be said to be unqualified and needs to be re-prepared. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The following describes the embodiments of the present invention based on its overall structure.

[0024] See also Figure 1-4 A device for detecting the compressive strength of a magnesium-aluminum alloy top cover casting comprises a substrate 1, a support plate 2 is equidistantly installed on the top of the substrate 1, a groove 3 is opened in the top center of the substrate 1, a clamping mechanism 4 is equidistantly installed inside the groove 3, a baffle mechanism 5 is equidistantly provided on the top of the substrate 1, a support seat 6 is installed on the top of the substrate 1, and a detection mechanism 7 is equidistantly installed on the top of the support seat 6.

[0025] like Figure 1-4 As shown, the clamping mechanism 4 includes a rotating rod 401 rotatably installed inside the groove 3, and the outer wall of the rotating rod 401 is equidistantly provided with bidirectional threads 402, and threaded seats 403 are installed at both ends of the outer wall of the bidirectional threads 402, and the top of the threaded seat 403 is connected to an arc block 404, and one end of the arc block 404 is connected to a clamping plate 405. The rotation of the rotating rod 401 can be controlled by a motor with existing technology, so that the two threaded seats 403 can be controlled to move toward or away from each other through the bidirectional threads 402, so that the top cover placed on the top of the support plate 2 can be clamped and fixed, and the top cover is moved toward the center position of the support plate 2 during the clamping process, and the top cover castings of the same width can be clamped at the same time, which is convenient for the subsequent compression resistance testing of multiple groups of top cover castings at the same time.

[0026] like Figure 1-4As shown, the baffle mechanism 5 includes a slot 501 equidistantly arranged at the front and rear ends of the top of the base plate 1 in the direction of the vertical groove 3, and an electric telescopic rod 502 is installed on the side of the inside of the slot 501 away from the support plate 2. The other end of the electric telescopic rod 502 is connected to a movable block 503, and the top of the movable block 503 is connected to a first baffle 504. After the top cover casting is clamped, the movable block 503 can be driven to move toward the direction of the support plate 2 by extending the electric telescopic rod 502, so that the first baffle 504 can be attached to the front and rear ends of the support plate 2.

[0027] like Figure 1-4 As shown, the baffle mechanism 5 also includes a second slot 505 equidistantly opened at the front and rear ends of the top of the base plate 1 and located on both sides of the support plate 2. The extension direction of the second slot 505 is parallel to the extension direction of the groove 3. The inside of the second slot 505 is connected to the side away from the support plate 2 with an electric telescopic rod 506, and the other end of the electric telescopic rod 506 is connected to a movable block 507. The top of the movable block 507 is connected to a second baffle 508. The extension of the second electric telescopic rod 506 can drive the movable block 507 to move toward the support plate 2, so that the second baffle 508 can be attached to the front and rear ends of the support plate 2, and cooperate with the first baffle 504 to seal the outside of the support plate 2. When the top cover casting is subjected to a pressure test, if the top cover casting fails, when debris splashes in the top area of ​​the top cover casting, the debris can be blocked at the top of the support plate 2 to avoid the safety hazards caused by the splashing of debris.

[0028] like Figure 1-4 As shown, a through hole 8 for accommodating the movement of the arc block 404 is opened on one side of the second baffle 508, and the movement of the arc block 404 is facilitated by the opened through hole 8.

[0029] like Figure 1-4 As shown, the detection mechanism 7 includes a hydraulic rod 701 equidistantly installed on the top of the support seat 6, the telescopic end of the hydraulic rod 701 passes through the support seat 6 and is connected to a pressure sensor 702, the bottom of the pressure sensor 702 is connected to a pressure plate 703, and the bottom of the pressure plate 703 is equidistantly installed with a detection head 704. When the compressive strength of the top cover casting is tested, the hydraulic rod 701 is first controlled to extend through the PLC system of the prior art so that the detection head 704 just fits the top of the top cover casting. At this time, the value of the pressure sensor 702 is zero, and multiple points on the top of the top cover casting can be detected at the same time, which is more effective. Then the hydraulic rod 701 drives the detection head 704 to squeeze the top cover casting until the pressure sensor 702 reaches the pre-set pressure value to ensure that the top cover casting is qualified. After the pressure sensor 702 reaches the pre-set pressure value, the pressure value persists for a period of time. If the top cover casting is not damaged, it can be said to be qualified. If it is damaged, it can be said to be unqualified and needs to be re-prepared.

[0030] Working principle: When in use, the motor of the existing technology can control the rotation of the rotating rod 401, thereby controlling the two threaded seats 403 to move toward or away from each other through the bidirectional thread 402, so that the top cover placed on the top of the support plate 2 can be clamped and fixed, and the top cover is moved toward the center position of the support plate 2 during the clamping process, so that top cover castings of the same width can be clamped at the same time, which is convenient for the subsequent simultaneous pressure resistance testing of multiple groups of top cover castings. After the top cover casting is clamped, the electric telescopic rod 1 502 is extended to drive the movable block 1 503 to move toward the direction of the support plate 2, so that the first baffle 504 can be attached to the front and rear end of the support plate 2. The electric telescopic rod 2 506 is extended to drive the movable block 2 507 to move toward the direction of the support plate 2, so that the second baffle 508 can be attached to the front and rear end of the support plate 2, and cooperate with the first baffle 504 to seal the outer side of the support plate 2. When the top cover casting is subjected to a pressure test and the top cover casting fails to meet the requirements, when fragments splash in the top area of ​​the top cover casting, the fragments can be blocked on the top of the support plate 2 to avoid safety hazards caused by the splashing of fragments. When the top cover casting is subjected to a compressive strength test, the hydraulic rod 701 is first controlled to extend through the PLC system of the prior art so that the detection head 704 just fits the top of the top cover casting. At this time, the value of the pressure sensor 702 is zero, and the top of the top cover casting can be tested at multiple points at the same time, which is more effective. Then the hydraulic rod 701 drives the detection head 704 to squeeze the top cover casting until the pressure sensor 702 reaches the pre-set pressure value to ensure that the top cover casting is qualified. After the pressure sensor 702 reaches the pre-set pressure value, and the pressure value persists for a period of time, if the top cover casting is not damaged, it can be said to be qualified. If damage occurs, it can be said to be unqualified and needs to be re-prepared.
