Description

Technical Field

[0001] This utility model belongs to the technical field of tilting impact testing machines, and specifically relates to an adjustable tilting impact composite testing machine. Background Technology

[0002] The inclined impact composite tester is a testing device used to simulate the inclined impact force that a product is subjected to during transportation or use. It is mainly used to evaluate the impact resistance of products such as packaging, electronic products, and automotive parts.

[0003] During the test, in order to obtain the ultimate impact resistance data of the sample, the impact intensity needs to be gradually increased. When the impact stress exceeds the sample's strength limit, the cracks rapidly propagate along the grain boundaries or defects, leading to sudden fracture and forming sharp fragments. These sharp fragments can easily fly out and cause injury. Utility Model Content

[0004] To address the problem that when the impact stress exceeds the sample's strength limit, cracks rapidly propagate along grain boundaries or defects, leading to sudden fracture and the formation of sharp fragments that can easily fly out and cause injury, this invention proposes an adjustable tilting impact composite testing machine to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adjustable tilting impact composite testing machine, including a base. An impact component and a buffer baffle are respectively arranged on the top of the base. A first protective component and a second protective component are respectively arranged inside the impact component. An opening and closing component is arranged on the top of the first protective component. The impact component is used to move the test sample. The first and second protective components are used to prevent fragments of the test sample from splashing. The opening and closing component is used to open the first protective component.

[0007] Furthermore, the impact assembly includes a guide frame, which is rotatably connected to the base. An electric push rod is rotatably connected to the outer surface of the guide frame, and the fixed end of the electric push rod is rotatably connected to the base. A drive box is fixedly installed on the top of the guide frame, and a drive screw is drivenly connected to the outer surface of the drive box. The drive screw is rotatably connected to the guide frame, and a movable stage is threadedly connected to the outer surface of the drive screw. An electromagnet is fixedly installed on the outer surface of the movable stage, and a sample platform is slidably connected to the outer surface of the guide frame.

[0008] Furthermore, the first protective component includes an adjusting screw, which is rotatably connected to the sample platform. A protective cover is threadedly connected to the outer surface of the adjusting screw, and the protective cover is slidably connected to the sample platform. A handwheel is fixedly connected to the outer surface of the adjusting screw.

[0009] Furthermore, the second protective component includes a protective plate, which is slidably connected to the protective cover and the sample platform respectively. A spring is fixedly connected inside the protective plate, and a sliding plate is fixedly connected to the upper end of the spring. A ball bearing is rotatably connected inside the sliding plate, and the sliding plate is slidably connected inside the protective plate. A square rod is fixedly connected to the outer surface of the protective plate.

[0010] Furthermore, the opening and closing assembly includes a rotating plate, which is rotatably connected to the protective cover. An ear plate is fixedly installed on the outer surface of the rotating plate, and a bolt is threaded onto the outer surface of the ear plate.

[0011] Furthermore, handles are fixedly connected to the outer surfaces of both the protective plate and the rotating plate.

[0012] Furthermore, a support column is fixedly connected to the top of the base, and the support column is fixedly connected to the buffer baffle.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects the first protective component and the second protective component.

This allows the system to protect samples of different sizes and prevent fragments from flying out and injuring people when testing the ultimate impact resistance of the sample.

[0015] 2. This utility model uses the connection between the protective plate and the square rod. During the test, the protective plate and the protective cover can prevent the fragments from flying out. After the test is completed, the protective plate is pulled to move it away from the test sample. During the movement, the protective plate drives the square rod to push the fragments to move, so that the fragments are moved to the bottom of the rotating plate. Then the rotating plate is rotated to open, and the fragments can be cleaned up.

[0026] 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.

[0027] 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.

[0028] Please see Figures 1-6 As shown, this utility model is an adjustable tilting impact composite testing machine, including a base 1. An impact component 2 and a buffer baffle 3 are respectively arranged on the top of the base 1. A first protective component 4 and a second protective component 5 are respectively arranged inside the impact component 2. An opening and closing component 6 is arranged on the top of the first protective component 4. The impact component 2 is used to move the test sample. The first protective component 4 and the second protective component 5 are used to prevent fragments of the test sample from splashing. The opening and closing component 6 is used to open the first protective component 4.

[0029] Adjust the first protective component 4 and the second protective component 5 to increase the distance between the first protective component 4 and the second protective component 5 and the impact component 2. Place the sample to be tested between the impact component 2, the first protective component 4 and the second protective component 5, and then move the first protective component 4 and the second protective component 5 in the opposite direction to bring them closer to the sample. Adjust the angle of the impact component 2 and move the sample so that the sample collides with the buffer baffle 3. The test result is obtained based on the data from the force sensor inside the buffer baffle 3. The fragments generated by the impact will be blocked by the first protective component 4 and the second protective component 5. Move the second protective component 5 to push the fragments to the bottom of the opening and closing component 6. After opening and closing component 6 is opened, the fragments can be removed.

[0030] This invention connects the first protective component 4 and the second protective component 5, both of which can slide on the surface of the impact component 2. This allows for adjustment of the gap between the impact component 2, the first protective component 4, and the second protective component 5, enabling protection of samples of different sizes and preventing fragments from flying out and injuring people when testing the ultimate impact resistance of the sample.

[0031] In one embodiment, the impact assembly 2 includes a guide frame 201, which is rotatably connected to a base 1. An electric push rod 202 is rotatably connected to the outer surface of the guide frame 201, and the fixed end of the electric push rod 202 is rotatably connected to the base 1. A drive box 203 is fixedly installed on the top of the guide frame 201, and a drive screw 204 is drively connected to the outer surface of the drive box 203. The drive screw 204 is rotatably connected to the guide frame 201, and a moving stage 205 is threadedly connected to the outer surface of the drive screw 204. An electromagnet 206 is fixedly installed on the outer surface of the moving stage 205, and a sample platform 207 is slidably connected to the outer surface of the guide frame 201.

[0032] After the sample is placed on top of the sample platform 207, the motor in the drive box 203 is started. The motor in the drive box 203 drives the drive screw 204 to rotate. The rotation trend of the moving stage 205 on the drive screw 204 is blocked by the guide frame 201. At this time, the drive screw 204 can drive the moving stage 205 to move along the guide frame 201. When the moving stage 205 approaches the sample platform 207, the electromagnet 206 is activated to attract the sample platform 207. Then the drive screw 204 drives the moving stage 205 and the sample platform 207 to the high position of the guide frame 201. Then the electromagnet 206 is de-energized and releases the sample platform 207. The sample platform 207 drives the test sample to slide down along the guide frame 201 and collide with the buffer baffle 3. The force sensor in the buffer baffle 3 records the data.

[0033] In one embodiment, the first protective component 4 includes an adjusting screw 401, which is rotatably connected to the sample platform 207. A protective cover 402 is threadedly connected to the outer surface of the adjusting screw 401, and the protective cover 402 is slidably connected to the sample platform 207. A handwheel 403 is fixedly connected to the outer surface of the adjusting screw 401.

[0034] Rotating the handwheel 403 causes the adjusting screw 401 to rotate. The rotational tendency of the protective cover 402 on the adjusting screw 401 is blocked by the sample platform 207. At this time, the adjusting screw 401 can drive the protective cover 402 to slide up and down, thereby adjusting the gap between the protective cover 402 and the sample platform 207, so as to facilitate the placement of test samples of different sizes between the protective cover 402 and the sample platform 207.

[0035] In one embodiment, the second protective component 5 includes a protective plate 501, which is slidably connected to the protective cover 402 and the sample platform 207 respectively. A spring 502 is fixedly connected inside the protective plate 501, and a sliding plate 503 is fixedly connected to the upper end of the spring 502. A ball bearing 504 is rotatably connected inside the sliding plate 503, and the sliding plate 503 is slidably connected inside the protective plate 501. A square rod 505 is fixedly connected to the outer surface of the protective plate 501.

[0036] Pushing the protective plate 501 to move it allows both sets of protective plates 501 to simultaneously approach the test sample from both sides and cooperate with the protective cover 402, preventing fragments of the test sample from flying out. When the protective cover 402 moves upward, the spring 502 compressed by the protective cover 402 gradually pushes the sliding plate 503 upward, so that the sliding plate 503 always presses against the protective cover 402, preventing the gap between the sliding plate 503 and the protective cover 402 from being too large and causing fragments to fly out.

[0037] In one embodiment, the opening and closing component 6 includes a rotating plate 601, which is rotatably connected to the protective cover 402. An ear plate 602 is fixedly installed on the outer surface of the rotating plate 601, and a bolt 603 is threadedly connected to the outer surface of the ear plate 602.

[0038] After the test is completed, pull the protective plates 501 away from each other. The protective plates 501 drive the square rod 505 to move. The square rod 505 pushes the fragments between the protective cover 402 and the protective plates 501 to the bottom of the rotating plate 601. The rotating bolt 603 removes it from the surface of the ear plate 602, releasing the limiting fixation between the ear plate 602 and the protective cover 402. The rotating plate 601 and the ear plate 602 can be pulled to rotate and open. At this time, the fragments can be cleared out.

[0039] In one embodiment, for the aforementioned protective plate 501, both the outer surfaces of the protective plate 501 and the rotating plate 601 are fixedly connected with handles 7.

[0040] The handle 7 provides a point of leverage for pulling the protective plate 501 and the rotating plate 601. The outer surface of the handle 7 is covered with a rubber layer to increase friction and improve grip comfort.

[0041] In one embodiment, for the base 1, a support column 8 is fixedly connected to the top of the base 1, and the support column 8 is fixedly connected to the buffer baffle 3.

[0042] There are multiple sets of support pillars 8. These multiple sets of support pillars 8 serve to connect the buffer baffle 3 and the base 1 and support the buffer baffle 3 to prevent the buffer baffle 3 from tilting due to excessive impact force.

[0043] In summary, the working principle of this utility model is as follows: Rotating the handwheel 403 causes the adjusting screw 401 to rotate, which in turn drives the protective cover 402 to slide up and down, thereby adjusting the gap between the protective cover 402 and the sample platform 207. After placing the test sample between the protective cover 402 and the sample platform 207, the protective plate 501 is pushed to move, causing both sets of protective plates 501 to simultaneously approach the test sample from both sides. The motor inside the drive box 203 is activated, driving the drive screw 204 to rotate. The rotational tendency of the moving stage 205 on the drive screw 204 is blocked by the guide frame 201. At this time, the drive screw 204 can drive the moving stage 205 to move along the guide frame 201. When the moving stage 205 approaches the sample platform 207, the electromagnet 206 is activated to attract the sample platform 207. Subsequently, the drive screw... Rod 204 moves the moving stage 205 and sample platform 207 to the high position of guide frame 201. Then, electromagnet 206 is de-energized and releases sample platform 207. Sample platform 207 moves the test sample down along guide frame 201 and collides with buffer baffle 3. Force sensor in buffer baffle 3 records data. Two sets of protective plates 501 and protective cover 402 cooperate to prevent fragments of test sample from flying out. After the test, the protective plates 501 are pulled away from each other. Protective plates 501 move square rod 505. Square rod 505 pushes the fragments between protective cover 402 and protective plate 501 to the bottom of rotating plate 601. Rotating bolt 603 removes it from the surface of ear plate 602, releasing the limiting fixation between ear plate 602 and protective cover 402. Rotating plate 601 and ear plate 602 can be pulled to rotate and open, at which time the fragments can be cleared out.

[0044] Through the above technical solution, 1. through the connection of the first protective component 4 and the second protective component 5, both the first protective component 4 and the second protective component 5 can slide on the surface of the impact component 2, thereby adjusting the gap between the impact component 2, the first protective component 4 and the second protective component 5, so that it can protect samples of different sizes and prevent fragments from flying out and injuring people when testing the ultimate impact resistance performance of the sample.

[0045] 2. Through the connection of the protective plate 501 and the square rod 505, the protective plate 501 and the protective cover 402 can prevent the fragments from flying out during the test. After the test is completed, the protective plate 501 is pulled to move it away from the test sample. During the movement, the protective plate 501 drives the square rod 505 to push the fragments to move, so that the fragments move to the bottom of the rotating plate 601. Then, the rotating plate 601 is rotated to open, and the fragments can be cleaned up.
