Description

Technical Field

[0001] This utility model belongs to the field of building material testing technology, and specifically relates to a shear test fixture for aluminum alloy thermal insulation profiles. Background Technology

[0002] Aluminum alloy thermal insulation profiles are composite profiles made by connecting aluminum alloy profiles with thermal insulation materials. They achieve thermal insulation by interrupting the heat transfer between metals. The production process is divided into casting type and strip type. The casting type involves injecting liquid thermal insulation material and solidifying it to form a composite structure. The strip type involves inserting toothed strips and then rolling them to fix the strip thermal insulation material.

[0003] By cutting appropriately sized specimens from standard-compliant aluminum alloy thermal insulation profiles, ensuring the integrity and consistency of the specimens, and then clamping and fixing the specimens in a test fixture, shear force is applied to the specimens according to the test standards until the specimens break. The shear strength and performance of the specimens are evaluated by recording various data during the test process.

[0004] In existing technologies, the sample is usually placed inside the fixture, and then the fixture is used to clamp and fix the upper and lower ends of the sample. However, during the clamping and fixing process, the position of the sample is easily offset from the horizontal plane between the fixture, and the center of the sample is easily deviated from the plane on which the shear force is applied. This makes it easy for the sample to shift during the shear force test, affecting the test data of the sample. Utility Model Content

[0005] To address the problem that placing the sample inside a fixture and then clamping and fixing the upper and lower ends of the sample during the clamping and fixing process can easily cause the position of the sample to shift from the horizontal plane between the fixture and the sample, and can easily cause the center of the sample to deviate from the plane on which the shear force is applied, thus causing the sample to shift during the shear force test and affecting the test data, this utility model proposes a shear test fixture for aluminum alloy thermal insulation profiles to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a shear test fixture for aluminum alloy thermal insulation profiles, including a base plate: The base plate is respectively provided with a first clamping assembly, a support assembly, a transmission assembly, a second clamping assembly, and an adjustment assembly; The first clamping assembly has its bottom end slidably disposed inside the base plate, so that the first clamping assembly can move along the direction of the base plate to adjust the position of the first clamping assembly; A support component is fixedly installed on one side of a transmission component so that the transmission component is moved when the support component moves. The second clamping assembly is fixedly mounted on one side to the side of the transmission assembly so that the second clamping assembly is driven to move when the transmission assembly moves. An adjusting component is fixedly mounted on one side of a second clamping component to adjust the clamping distance of the second clamping component.

[0007] Furthermore, the first clamping assembly includes a support platform, the bottom end of which is slidably disposed with the interior of the base plate, a fixing bolt is threadedly connected to the interior of the support platform, and a clamping block is rotatably disposed at the bottom end of the fixing bolt.

[0008] Furthermore, the support assembly includes a mounting bracket, one side of which is fixedly mounted to one side of the support platform. A telescopic rod is fixedly mounted on one side of the mounting bracket, a push plate is fixedly mounted on one end of the telescopic rod, a spring is fixedly mounted on one side of the push plate, and one end of the spring is fixedly mounted to one side of the mounting bracket.

[0009] Furthermore, the transmission assembly includes a connecting seat, one side of which is fixedly installed with one side of the push plate. A transmission rod is rotatably mounted inside the connecting seat, and a connecting frame is rotatably mounted at one end of the transmission rod.

[0010] Furthermore, the second clamping assembly includes a movable plate, the outer surface of which is slidably disposed with the interior of the mounting frame, one side of which is fixedly mounted with one side of the connecting frame, a guide rod slidably disposed inside the movable plate, and a clamping plate fixedly mounted at one end of the guide rod.

[0011] Furthermore, the adjustment assembly includes a rotating seat, one side of which is fixedly installed with one side of the movable plate. A threaded rod is rotatably provided inside the rotating seat, and a handle is fixedly installed at one end of the threaded rod. A threaded seat is threadedly connected to the threaded surface of the threaded rod, and one side of the threaded seat is fixedly installed with one side of the clamping plate.

[0012] Furthermore, the adjustment assembly also includes a support base, one side of which is fixedly installed with one side of the mounting bracket. A connecting cylinder is rotatably arranged inside the support base, and a hexagonal block is slidably arranged inside the connecting cylinder. One side of the hexagonal block is fixedly installed with one end of the threaded rod.

[0013] This utility model has the following beneficial effects: 1. This utility model moves a support component that drives a transmission component mounted on one side to move. During the movement of the transmission component, the second clamping component mounted on the same side moves, thereby gradually increasing the distance between the second clamping components. This allows the sample to be placed inside the first clamping component, with one side of the sample fitting against one side of the support component. Then, the support component is released to reset, causing the support component to drive the transmission component to reset as well. This allows the transmission component to drive the second clamping component to clamp both sides of the sample. During the clamping process, the sample is pushed towards the center of the first clamping component, thus facilitating the restriction of the sample's position within the first clamping component and preventing sample displacement during clamping from affecting the test data.

[0014] 2. This utility model moves the connecting seat installed on one side by pushing the push plate, so that the connecting seat pushes the internally rotating transmission rod to move, thereby causing the other end of the transmission rod to move the internally rotating connecting frame. This allows the connecting frame to move the movable plate installed on one side along the inside of the mounting frame, so that the movable plate, in conjunction with the internally sliding guide rod, moves the clamping plate to position and clamp the sample.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-6 As shown, this utility model is a shear test fixture for aluminum alloy thermal insulation profiles, including a base plate 1: The base plate 1 is respectively provided with a first clamping assembly 2, a support assembly 3, a transmission assembly 4, a second clamping assembly 5, and an adjustment assembly 6; The first clamping component 2 has its bottom end slidably disposed inside the base plate 1 so that the first clamping component 2 can move along the direction of the base plate 1 for adjusting the position of the first clamping component 2; The support component 3 is fixedly installed on one side of the transmission component 4 so that the transmission component 4 is moved when the support component 3 moves. The second clamping assembly 5 is fixedly installed on one side of the transmission assembly 4 so that the second clamping assembly 5 is driven to move when the transmission assembly 4 moves. The adjusting component 6 is fixedly installed on one side of the second clamping component 5 so that the adjusting component 6 can adjust the clamping distance of the second clamping component 5.

[0022] In use, the first clamping assembly 2 is fixed to the base plate 1, and the base plate 1 is installed on the shear testing device. Then, the support assembly 3 is pushed to move the transmission assembly 4 installed on one side. During the movement of the transmission assembly 4, the second clamping assembly 5 installed on one side is moved, thereby gradually increasing the distance between the second clamping assemblies 5. This allows the sample to be placed inside the first clamping assembly 2, with one side of the sample adhering to one side of the support assembly 3. Then, the support assembly 3 is released to reset, allowing the support assembly 3 to drive the transmission assembly 4 to reset as well. This allows the transmission assembly 4 to drive the second clamping assembly 5 to clamp both sides of the sample, and during the clamping process, it can push the sample towards the center of the first clamping assembly 2. Then, the first clamping assembly 2 is rotated, causing it to move downwards during rotation, so that the first clamping assembly 2 clamps and fixes the upper and lower ends of the sample. By rotating the adjustment assembly 6, the second clamping assembly 5 installed on one side can be moved, thereby adjusting the clamping width range of the second clamping assembly 5. This invention moves the support component 3, causing the transmission component 4 mounted on one side to move. During this movement, the transmission component 4 moves the second clamping component 5 mounted on the other side, gradually increasing the distance between the second clamping components 5. This allows the sample to be placed inside the first clamping component 2, with one side of the sample aligning with one side of the support component 3. The support component 3 is then released for resetting, causing it to move the transmission component 4 back to its original position. This allows the transmission component 4 to move the second clamping components 5 to clamp both sides of the sample. Furthermore, during clamping, the sample is pushed towards the center of the first clamping component 2, thus restricting the sample's position within the first clamping component 2 and preventing sample displacement during clamping that could affect the test data.

[0023] In one embodiment, the first clamping assembly 2 includes a support platform 201, the bottom end of which is slidably disposed with the interior of the base plate 1, a fixing bolt 202 is threadedly connected to the interior of the support platform 201, and a clamping block 203 is rotatably disposed at the bottom end of the fixing bolt 202.

[0024] By placing the sample inside the support platform 201 and then rotating the fixing bolt 202 to move it downward along the direction of the support platform 201, the fixing bolt 202 drives the clamping block 203 with its bottom end to move downward, and the bottom end of the clamping block 203 is in contact with the top surface of the sample, thereby clamping and fixing the sample with friction.

[0025] In one embodiment, the support component 3 includes a mounting frame 301. One side of the mounting frame 301 is fixedly mounted to one side of the support platform 201. A telescopic rod 302 is fixedly mounted to one side of the mounting frame 301. A push plate 303 is fixedly mounted to one end of the telescopic rod 302. A spring 304 is fixedly mounted to one side of the push plate 303. One end of the spring 304 is fixedly mounted to one side of the mounting frame 301.

[0026] By pushing the push plate 303 to compress the spring 304 and telescopic rod 302 fixed on one side, the push plate 303 moves towards the mounting bracket 301 along the direction of the telescopic rod 302. When the force applied to the push plate 303 disappears, it can cooperate with the spring 304 to release the compressive stress and drive the push plate 303 to reset along the direction of the telescopic rod 302, which is quite convenient.

[0027] In one embodiment, the transmission assembly 4 includes a connecting seat 401, one side of which is fixedly installed with one side of the push plate 303. A transmission rod 402 is rotatably disposed inside the connecting seat 401, and a connecting frame 403 is rotatably disposed at one end of the transmission rod 402.

[0028] When the push plate 303 moves closer to one side of the mounting frame 301 along the direction of the telescopic rod 302, it can drive the connecting seat 401 mounted on one side to move, so that the connecting seat 401 pushes the internally rotating transmission rod 402 to move, thereby causing the other end of the transmission rod 402 to drive the internally rotating connecting frame 403 to move. Since the transmission rod 402 is set at a certain angle with the connecting seat 401 and the connecting frame 403, when the transmission rod 402 drives the connecting frame 403 to move, the connecting frame 403 can move along the horizontal direction of the mounting frame 301.

[0029] In one embodiment, the second clamping assembly 5 includes a movable plate 501, the outer surface of the movable plate 501 is slidably disposed with the interior of the mounting bracket 301, one side of the movable plate 501 is fixedly mounted with one side of the connecting bracket 403, a guide rod 502 is slidably disposed inside the movable plate 501, and a clamping plate 503 is fixedly mounted at one end of the guide rod 502.

[0030] When the connecting frame 403 moves along with the transmission rod 402, it can drive the movable plate 501 installed on one side to move along the inside of the mounting frame 301. This causes the movable plate 501 to move in conjunction with the guide rod 502 that is slidably set inside, thereby driving the clamping plate 503 to move so that the clamping plate 503 can position and clamp the sample.

[0031] In one embodiment, the adjustment component 6 includes a rotating seat 601, one side of which is fixedly installed with one side of the moving plate 501. A threaded rod 602 is rotatably provided inside the rotating seat 601. A handle 603 is fixedly installed at one end of the threaded rod 602. A threaded seat 604 is threadedly connected to the threaded surface of the threaded rod 602. One side of the threaded seat 604 is fixedly installed with one side of the clamping plate 503. The adjustment assembly 6 also includes a support base 605, one side of which is fixedly installed on one side of the mounting bracket 301. A connecting cylinder 606 is rotatably arranged inside the support base 605, and a hexagonal block 607 is slidably arranged inside the connecting cylinder 606. One side of the hexagonal block 607 is fixedly installed on one end of the threaded rod 602.

[0032] By rotating the handle 603, the threaded rod 602 installed on one side is rotated, so that the threaded rod 602 drives the threaded seat 604 connected to the threaded surface to move, thereby enabling the threaded seat 604 to drive the clamping plate 503 installed on one side to move, so as to adjust the clamping width of the clamping plate 503. Since both the adjusting component 6 and the second clamping component 5 are provided with two sets, the two sets of threaded rods 602 cooperate with the hexagonal block 607 fixed at one end and the connecting cylinder 606 to transmit power. When one set of threaded rods 602 rotates, it can drive one set of hexagonal blocks 607 to drive the connecting cylinder 606 to rotate. Thus, the connecting cylinder 606, together with the other set of hexagonal blocks 607, drives the other set of threaded rods 602 to rotate synchronously. Moreover, the internal sliding arrangement of the hexagonal block 607 and the connecting cylinder 606 allows the two sets of threaded rods 602 to move synchronously in opposite directions, thereby improving the practicality of the aluminum alloy thermal insulation profile shear test fixture.

[0033] Through the above technical solution, 1. By pushing the support component 3 to move the transmission component 4 installed on one side, the transmission component 4 moves and drives the second clamping component 5 installed on one side to move, thereby gradually increasing the distance between the second clamping components 5. This allows the sample to be placed inside the first clamping component 2, and one side of the sample to be in contact with one side of the support component 3. Then, the support component 3 is released to reset, and the support component 3 drives the transmission component 4 to reset during the reset process. This allows the transmission component 4 to drive the second clamping component 5 to clamp both sides of the sample, and pushes the sample towards the middle of the first clamping component 2 during the clamping process. This makes it easier to limit the position of the sample in the first clamping component 2 and avoid the sample shifting during the clamping process, which would affect its test data. 2. By pushing the push plate 303, the connecting seat 401 installed on one side is moved, so that the connecting seat 401 pushes the internally rotating transmission rod 402 to move, so that the other end of the transmission rod 402 drives the internally rotating connecting frame 403 to move, so that the connecting frame 403 drives the movable plate 501 installed on one side to move along the inside of the mounting frame 301, so that the movable plate 501, in conjunction with the internally sliding guide rod 502, drives the clamping plate 503 to move, so that the clamping plate 503 positions and clamps the sample.
