Description

[0002] As the name suggests, aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials. After the production of aluminum alloy plates is completed, it is necessary to conduct random inspections on the same batch of aluminum alloy plates to test whether their tensile strength meets the national standard or industry standard. Generally, the tensile strength of aluminum alloy plates is tested using a tensile strength testing machine.

[0003] Some models of tensile strength testing machines currently in use have a closing door installed at the hydraulic stretching part. After the workpiece is placed in, the closing door is closed to prevent workpiece debris from splashing during stretching and injuring the operator. The process generally involves opening the closing door, placing the workpiece in the fixture for clamping, and then closing the closing door. The steps are relatively cumbersome, resulting in slow detection efficiency.

[0036] The lower fixture 6 includes a vertical plate 601, which is fixedly arranged at the upper end of the guide plate 7. A placement slot 602 is opened at the front of the vertical plate 601, and a driving motor 603 is fixedly arranged in the placement slot 602. A worm 604 is fixedly arranged at the output end of the driving motor 603. One side of the worm 604 is meshedly connected to a first worm gear 605. The first worm gear 605 is rotatably connected to the front of the vertical plate 601. A cantilever 606 is fixedly arranged at the front of the first worm gear 605. One end of the cantilever 606 is rotatably connected to a clamping plate 607. The front of the clamping plate 607 is rotatably connected to a limit plate 608. One end of the limit plate 608 is rotatably connected to the front of the vertical plate 601.

[0037] The front portion of the worm 604 is meshedly connected to a second worm gear 8, and a connecting member 9 is fixedly provided inside the second worm gear 8. The connecting member 9 is used to open and close the closed door 10;

[0038] A storage component responsible for collecting workpieces is embedded and connected to the front end of the closed door 10.

[0039] In this embodiment, the drive motor 603 is started, and the drive motor 603 drives the worm 604 to rotate. The worm 604 also drives the two sets of first worm gears 605 to rotate in opposite directions. Under the action of the cantilever 606 and the limit plate 608, the clamping plate 607 approaches and prepares to clamp the aluminum alloy plate. At the same time, the second worm gear 8 rotates accordingly, and the second worm gear 8 drives the connecting member 9. The connecting member 9 pulls the closed door 10, thereby closing the closed door 10 while clamping the workpiece, thereby enhancing its linkage, reducing the number of manual operations, and improving detection efficiency.

[0040] It is worth mentioning that before testing, aluminum alloy parts of different specifications need to be cut into specifications that meet the requirements of the device.

[0041] 1 and 3 , in a preferred embodiment, the storage member includes a collection frame 11 , which is embedded in the front end of the closed door 10 , and a filling pad 12 is fixedly provided on the front of the guide plate 7 near the lower end of the closed door 10 .

[0042] In this embodiment: when the driving motor 603 drives the worm 604 to rotate in the opposite direction and releases the workpiece, the closed door 10 opens and is in a tilted state, and its aluminum alloy plate falls onto the guide plate 7. The filling pad 12 fills the gap between the closed door 10 and the guide plate 7. The workpiece slides along the tilted guide plate 7 to the closed door 10 and slides into the collection frame 11 along the closed door 10, so that the aluminum alloy plate can be collected without manual removal, thereby further improving the degree of automation of the device.

[0043] 1 and 8 , in a preferred embodiment, the second worm gear 8 includes an annular plate 801, which is arranged at the front end of the worm 604. An end plate 802 is fixedly provided on the outer circumferential surface of the annular plate 801. A narrow groove 803 is provided at the upper end of the end plate 802. A spring 804 is fixedly provided on the inner bottom surface of the narrow groove 803. A baffle 805 is fixedly provided on the top of the spring 804. The baffle 805 is slidably connected in the narrow groove 803. Teeth 806 are fixedly provided on the upper end of the baffle 805, and the teeth 806 are meshingly connected to the front end of the worm 604.

[0044] In this embodiment: when the driving motor 603 drives the worm 604 to close the closed door 10, but there is a certain distance between the two sets of clamps 607 and the workpiece, since the closed door 10 has already rested against the front of the vertical frame 2 and cannot rotate any further, the worm 604 will squeeze the teeth 806, and the teeth 806 will be pushed into the narrow groove 803, compressing the spring 804, so that the two sets of clamps 607 can continue to approach and clamp the aluminum alloy plate. When the worm 604 rotates in the reverse direction, the teeth 806 are reset under the action of the spring 804, and will still drive the second worm wheel 8 to rotate in the reverse direction, so that the closed door 10 is opened.

[0045] 1 and 4 , in a preferred embodiment, the connecting member 9 includes a rotating shaft 901, which is fixedly provided on the inner circumference of the annular plate 801, and one end of the rotating shaft 901 is rotatably connected to the inner wall of the vertical frame 2. A transfer arm assembly for receiving the closed door 10 is fixedly provided on the rotating shaft 901, and the transfer arm assembly includes a connecting seat 902, a support arm 903 is fixedly provided in the connecting seat 902, and one end of the support arm 903 away from the connecting seat 902 is rotatably connected to the rotating arm 904, and one end of the rotating arm 904 away from the support arm 903 is rotatably connected to the support seat 905, and a T-shaped slider 906 is fixedly provided below the support seat 905, and the T-shaped slider 906 is slidably connected in the T-shaped slide groove 907, and the T-shaped slide groove 907 is opened in the closed door 10.

[0046] In this embodiment: when the rotating shaft 901 drives the two sets of connecting seats 902 to rotate, the connecting seats 902 drive the support arm 903 to rotate accordingly. While the support arm 903 rotates accordingly, the inclination angle between the support arm 903 and the rotating arm 904 changes. When the inclination angle between the support arm 903 and the rotating arm 904 decreases, the T-shaped slider 906 will be pulled to slide along the T-shaped slide groove 907, thereby rotating the closed door 10 and closing it. Similarly, when the inclination angle between the support arm 903 and the rotating arm 904 increases, the T-shaped slider 906 will be pushed to slide along the T-shaped slide groove 907, thereby pushing the closed door 10 to rotate and open, thereby being able to control the opening and closing of the closed door 10.

[0047] 2 and 3 , a material guide member 13 responsible for isolating workpieces is fixedly provided at the upper end of the closed door 10 near the T-shaped slide groove 907. The material guide member 13 includes a first material separator 1301. The first material separator 1301 is fixedly provided at the upper end of the closed door 10, and a second material separator 1302 is fixedly provided at the upper end of the material guide plate 7 near one end of the first material separator 1301.

[0048] In this embodiment, two symmetrical groups of first separators 1301 and second separators 1302 are provided to prevent the fallen aluminum alloy plates from sliding to other places, so that the fallen aluminum alloy plates can slide into the collection frame 11.

[0049] 1 , 7 and 9 , in a preferred embodiment, a pre-clamping mechanism 14 is fixedly provided on the upper end of the closed door 10 near the first material separator 1301, a partition 1402 is fixedly provided on the upper end of the pre-clamping mechanism 14, a guide hole 1403 is provided in the partition 1402, a guide rod 1404 is slidably connected in the guide hole 1403, a pre-clamping plate 1405 is fixedly provided on one end of the guide rod 1404, a pad 1406 is fixedly provided on one end of the guide rod 1404 away from the pre-clamping plate 1405, a first spring 1407 is fixedly provided on one side of the pad 1406 near one end of the guide rod 1404, the other end of the first spring 1407 passes through the guide rod 1404 and is fixedly provided on one side of the partition 1402, and a pushing member responsible for triggering the two groups of pre-clamps 1405 to move away is fixedly provided on the other side of the pad 1406.

[0050] In this embodiment: before testing, the two sets of pads 1406 are pulled to both sides. The pads 1406 drive the two sets of pre-clamps 1405 away from each other through the guide rods 1404, while stretching the first spring 1407. Then, the aluminum alloy plate that meets the requirements is placed between the two sets of pre-clamps 1405. Then, the two sets of pre-clamps 1405 are released. The two sets of pre-clamps 1405 are reset under the action of the first spring 1407 to pre-clamp the aluminum alloy plate.

[0051] 1 , 3 and 7 , in a preferred embodiment, the pusher includes a first connecting frame 1408 , which is fixedly provided on the other side of the pad 1406 , and one end of a connecting plate 1409 is rotatably connected to the first connecting frame 1408 , and the other end of the connecting plate 1409 is rotatably connected to a second connecting frame 1410 , and a contact plate 1411 is fixedly provided on one side of the second connecting frame 1410 , and a reset component responsible for resetting the pre-clamping plate 1405 is fixedly provided on one end of the contact plate 1411 , and the reset component includes a slide 1412 , and the slide 1412 is fixedly provided on one end of the contact plate 1411 , and the slide 1412 is longitudinally slidably connected to the guide frame 1413 , and the guide frame 1413 is fixedly provided on one side of the first material separator 1301 , and a second spring 1414 is fixedly provided on the lower end of the contact plate 1411 , and the end of the second spring 1414 is fixedly provided on the upper end of the closed door 10 .

[0052] In this embodiment: When the closed door 10 is fully closed, the aluminum alloy plate clamped by the two sets of pre-clamps 1405 is between the two sets of clamps 607, and the contact plate 1411 is against the sealing plate on the back. It moves along the guide frame 1413 through the slide plate 1412, compressing the second spring 1414 while pushing the second connecting frame 1410 to move. The second connecting frame 1410 drives one end of the connecting plate 1409 to move, changing the inclination angle of the connecting plate 1409, thereby pulling the pad 1406 to separate the two sets of pre-clamps 1405 and no longer clamping the aluminum alloy plate. At this time, after the two sets of clamps 607 approach, they clamp the lower end of the aluminum alloy plate to prepare for subsequent detection.

[0053] 1 to 9 , a method for using a device for detecting the tensile strength of an aluminum alloy includes the following steps:

[0054] S1: Place the aluminum alloy plate between the two sets of pre-clamping plates 1405, start the drive motor 603, and the drive motor 603 drives the two sets of first worm gears 605 to rotate toward each other through the worm 604, so that the two sets of clamping plates 607 gradually move closer;

[0055] S2: As the second worm gear 8 drives the rotating shaft 901 to rotate, the angles of the support arm 903 and the rotating arm 904 change, pulling the closed door 10 to rotate, causing the closed door 10 to gradually close. During the gradual closing process of the closed door 10, the workpiece clamped by the pre-clamping plate 1405 moves closer to the lower clamp 6;

[0056] S3: When the closed door 10 is closed, it rests against the front end of the vertical frame 2. At the same time, the clamp 607 clamps the aluminum alloy plate, and its contact plate 1411 is pressed, pulling the two sets of pre-clamps 1405 apart. The upper clamp 5 clamps the upper end of the aluminum alloy plate, and the hydraulic component 3 lifts the upper clamp 5 upward to test the tensile strength of the aluminum alloy plate.

[0057] Working principle: Before use, the aluminum alloy plate is cut into the specifications that meet the clamping requirements of the device. When in use, the two sets of pads 1406 are pulled to both sides. The pads 1406 drive the two sets of pre-clamping plates 1405 to move away from each other through the guide rods 1404, while stretching the first spring 1407. Then, the aluminum alloy plate that meets the requirements is placed between the two sets of pre-clamping plates 1405. Then, the two sets of pre-clamping plates 1405 are released. The two sets of pre-clamping plates 1405 are reset under the action of the first spring 1407 to pre-clamp the aluminum alloy plate. The drive motor 603 is started. The drive motor 603 drives the two sets of first worm gears 605 to rotate in opposite directions at the same time through the worm 604. The two sets When the first worm gear 605 drives the two groups of cantilevers 606 to rotate, under the action of the limit plate 608, the two groups of clamping plates 607 approach each other at the same time. In the process of the two groups of clamping plates 607 approaching each other, the second worm gear 8 follows the rotation, thereby driving the two groups of support arms 903 to rotate. The inclination angle between the support arm 903 and the rotating arm 904 is reduced, and the T-shaped slider 906 is pulled to slide along the T-shaped slide groove 907, so that the closed door 10 is closed while clamping the aluminum alloy plate. At the same time, the vertical seat 1401 rotates following the rotation of the closed door 10. When the closed door 10 is closed, the two ends of the aluminum alloy plate clamped by the two groups of pre-clamping plates 1405 are just placed on the upper clamp 5 and the lower clamp 6 The clamping plates 607 of the upper clamp 5 and the lower clamp 6 are close to each other to clamp the two ends of the aluminum alloy plate. At the same time, the contact plate 1411 is against the sealing plate on the back, and moves along the guide frame 1413 through the slide plate 1412. While compressing the second spring 1414, the second connecting frame 1410 is pushed to move. The second connecting frame 1410 drives one end of the connecting plate 1409 to move, changing the inclination angle of the connecting plate 1409, thereby pulling the pad 1406, separating the two sets of pre-clamps 1405, and no longer clamping the aluminum alloy plate to prevent detection errors. Then, the hydraulic component 3 pulls the upper clamp 5 to move upward until the aluminum alloy plate breaks, and then drives the motor 603. Rotate in the opposite direction, and the clamps 607 move away from each other, loosening the broken aluminum alloy plate. Similarly, the closed door 10 slowly opens, and after the broken aluminum alloy plate is loosened, it falls onto the guide plate 7, and slides along the inclined surface of the guide plate 7 to the connection between the closed door 10 and the guide plate 7. When the closed door 10 is fully opened and in a tilted state, the broken aluminum alloy plate continues to slide into the collection frame 11 along the inclined closed door 10, so there is no need to manually remove the aluminum alloy plates on the upper clamp 5 and the lower clamp 6. The overall linkage is strong, and the manual operation steps are only needed to pre-clamp the aluminum alloy plate between the two sets of pre-clamps 1405, which reduces the steps of manual operation and can effectively improve the detection efficiency.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
