Description

Technical Field

[0001] This utility model relates to the field of plastic fuel tank testing technology, and in particular to a plastic fuel tank impact testing device. Background Technology

[0002] After production, automotive plastic fuel tanks need to undergo impact tests to measure their crash resistance. However, conventional testing equipment, due to structural and design limitations, is often large in size and occupies a large area, and the steps and preparations for impact testing are quite complicated.

[0003] The existing patent CN209181990U describes a plastic fuel tank impact testing device, comprising a support and a base. A left and right vertical plate are connected to the base, with a front baffle connecting the front ends of the left and right vertical plates and a rear baffle connecting their rear ends. A right vertical plate opening is provided on the right vertical plate. An impact block is located on the base between the left and right vertical plates. The bottom of the impact block has multiple bottom universal rollers, and the front and rear ends of the impact block each have multiple front and rear universal rollers. A steel wire rope is connected to the right end of the impact block, with the other end passing through the right vertical plate opening and connected to a pull ring. Multiple helical springs are also connected between the impact block and the right vertical plate. By adopting this structure, the present invention is simple and quick to operate, thus greatly ensuring the efficiency and effectiveness of the impact test.

[0004] However, in the process of using the above method, the distance between the front baffle and the rear baffle of the fuel tank is fixed, which means that the device can only be used to conduct impact tests on fuel tanks of the same size. For fuel tanks of different sizes, the test device must be replaced, which increases the test cost. Utility Model Content

[0005] The purpose of this invention is to provide a plastic fuel tank impact testing device, which solves the problem of the aforementioned device that uses a fixed distance between the front and rear baffles of the fuel tank, which limits the impact test to fuel tanks of the same size. For fuel tanks of different sizes, the testing device must be replaced, increasing the testing cost.

[0006] To achieve the above objectives, this utility model provides a plastic fuel tank impact testing device, including a test platform, a side plate, and an impact device. The side plate is fixedly installed on the test platform, and the impact device is installed on the test platform. It also includes a limiting device, which comprises a limiting plate, a roller, an adjusting rod, a guide rod, and a rotating assembly. The adjusting rod is threadedly engaged with the side plate, and the limiting plate is rotatably connected to the adjusting rod. The guide rod is fixedly installed on the limiting plate and slidably engaged with the side plate. The limiting plate has a mounting groove, and the roller is rotatably installed on the limiting plate and located within the mounting groove. The rotating assembly is disposed on the adjusting rod.

[0007] The rotating assembly includes a connecting rod and a rotating ring, wherein the connecting rod is fixedly mounted on the adjusting rod, and the rotating ring is fixedly mounted on the connecting rod.

[0008] The test bench is also equipped with a buffer plate, which is fixedly installed on the test bench.

[0009] The impact device includes an impact block, a guide rail, an energy storage spring, and a moving component. The guide rail is fixedly installed on the test bench. The impact block is provided with a roller, which is located inside the guide rail. The energy storage spring is provided with a connecting block one and a connecting block two at its two ends, and the connecting block one and the connecting block two are detachably connected to the impact block and the test bench, respectively. The moving component is set on the test bench.

[0010] The moving component includes a moving frame, a drive frame, and a cylinder. The cylinder is mounted on the test bench. The moving frame is fixedly mounted on the output end of the cylinder. The drive frame is slidably mounted on the moving frame and contacts the impact block.

[0011] This utility model discloses an impact testing device for a plastic oil tank. In use, the oil tank is placed on the left side of the test bench, positioned between the limiting plates on both sides. The rotating ring then rotates, and the rotating ring, via the connecting rod, drives the adjusting rod to rotate. Since the adjusting rod is threadedly connected to the side plate, it moves towards the side of the test bench during rotation, causing the limiting plates on both sides to move closer together, thus bringing the roller into contact with the oil tank. The cylinder is then activated, and through the moving frame and the driving frame, the cylinder drives the impact block along the guide rail... The side away from the fuel tank slides, causing the energy storage spring to compress and store elastic potential energy. Then, it pulls the drive frame outward, causing the drive frame to disengage from the impact block. At this point, the impact block is no longer restrained and, driven by the energy storage spring, moves rapidly towards the fuel tank and impacts it, completing the impact test. The rotation of the adjusting rod by the rotating assembly causes the adjusting rod to drive the limiting plate to move and adjust on the side plate via the guide rod. This allows the limiting plate to fix fuel tanks of different sizes, enabling the entire device to meet the impact test requirements of fuel tanks of different sizes. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a plastic fuel tank impact testing device according to this utility model. Figure 2 This is a schematic diagram of the rotating assembly of this utility model. Figure 3 This is a schematic diagram of the limiting plate of this utility model.

[0020] This utility model provides a plastic fuel tank impact testing device, including a test platform 101, a side plate 102, and an impact device. It also includes a limiting device, which comprises a limiting plate 103, a roller 104, an adjusting rod 105, a guide rod 106, and a rotating assembly. The rotating assembly includes a connecting rod 108 and a rotating ring 109. A buffer plate 110 is also provided on the test platform 101. The impact device includes an impact block 111, a guide rail 112, an energy storage spring 113, and a moving assembly. The moving assembly includes a moving frame 116, a drive frame 117, and a cylinder 118. This solution solves the problem in the aforementioned device where the distance between the front and rear baffles of the fuel tank is fixed, limiting the impact test to fuel tanks of the same size. For fuel tanks of different sizes, the test device must be replaced, increasing testing costs.

[0021] In this embodiment, by moving and adjusting the limiting plate 103 on the side plate 102, the limiting plate 103 can fix oil tanks of different sizes, so that the whole device can meet the impact test of oil tanks of different sizes.

[0022] The adjusting rod 105 is threadedly engaged with the side plate 102, the limiting plate 103 is rotatably connected to the adjusting rod 105, the guide rod 106 is fixedly mounted on the limiting plate 103 and slidably engaged with the side plate 102, the limiting plate 103 is provided with a mounting groove 107, the roller 104 is rotatably mounted on the limiting plate 103 and located within the mounting groove 107, the rotating assembly is disposed on the adjusting rod 105, and the mounting grooves 107 on the limiting plate 103 are symmetrically arranged. The cylinder 104 is a hollow cylindrical structure. The adjusting rod 105 is threaded. The axis of the guide rod 106 is parallel to the axis of the adjusting rod 105. By placing the oil tank between the limiting plates 103 on both sides, the rotating assembly drives the adjusting rod 105 to rotate. The adjusting rod 105, through threaded transmission, causes the limiting plates 103 and the roller 104 to clamp the oil tank. This allows the limiting plates 103 to fix oil tanks of different sizes, enabling the entire device to meet the impact test requirements of oil tanks of different sizes.

[0023] Secondly, the connecting rod 108 is fixedly installed on the adjusting rod 105; the rotating ring 109 is fixedly installed on the connecting rod 108, the connecting rod 108 is arranged in a ring at the end of the adjusting rod 105, and the rotating ring 109 is welded to the outer end of the connecting rod 108. By rotating the rotating ring 109, the rotating ring 109 drives the connecting rod 108 to rotate, and the connecting rod 108 further drives the adjusting rod 105 to rotate.

[0024] Furthermore, the buffer plate 110 is fixedly installed on the test bench 101. The buffer plate 110 is made of rubber. By setting the buffer plate 110, the oil tank can be buffered, thus preventing the oil tank from damaging the side of the test bench 101.

[0025] Furthermore, the guide rail 112 is fixedly mounted on the test bench 101; the impact block 111 is provided with a roller 119, which is located inside the guide rail 112; the energy storage spring 113 has a connecting block 114 and a connecting block 115 at both ends, which are detachably connected to the impact block 111 and the test bench 101, respectively; the moving component is disposed on the test bench 101; the guide rail 112 is disposed on the upper and lower sides of the side of the test bench 101; and the impact block 111 is located on the upper and lower sets of the guide rail 112. Between them, the connecting block 114 and the connecting block 215 are respectively welded to both ends of the energy storage spring 113. The connecting block 114 and the connecting block 2 are disassembled and engaged with the impact block 111 and the test bench 101 by screws, so as to facilitate the replacement of the energy storage spring 113. The moving component drives the impact block 111 and the roller 119 to move along the guide rail 112, so that the impact block 111 compresses the energy storage spring 113, so that the energy storage spring 113 stores elastic potential energy, and drives the impact block 111 to impact the oil tank through the energy storage spring 113.

[0026] Finally, the cylinder 118 is mounted on the test bench 101; the movable frame 116 is fixedly mounted on the output end of the cylinder 118; the drive frame 117 is slidably mounted on the movable frame 116 and contacts the impact block 111. The cylinder 118 is fixed to the side of the test bench 101 by screws. The movable frame 116 has a square frame structure, and the drive frame 117 has a T-shaped structure. The output end of the cylinder 118 drives the movable frame 116 to move, so that the movable frame 116 drives the impact block 111 to move through the drive frame 117.

[0027] In this embodiment, during use, the oil tank is placed on the left side of the test bench 101, positioned between the limiting plates 103 on both sides. Then, the rotating ring 109 is rotated, and the rotating ring 109 drives the adjusting rod 105 to rotate via the connecting rod 108. Since the adjusting rod 105 is threadedly connected to the side plate 102, the adjusting rod 105 moves towards the side of the test bench 101 during rotation, causing the limiting plates 103 on both sides to move closer together, thus bringing the roller 104 against the oil tank. Then, the cylinder 118 is activated, and the cylinder 118 drives the impact block 111 along the guide rail 1 via the moving frame 116 and the driving frame 117. 12 slides away from the fuel tank, causing the energy storage spring 113 to compress and store elastic potential energy. Then, it pulls the drive frame 117 outward, causing the drive frame 117 to disengage from the impact block 111. At this time, the impact block 111 is no longer restricted and, driven by the energy storage spring 113, moves rapidly toward the fuel tank and impacts it, completing the impact test. The rotation of the adjusting rod 105 by the rotating assembly causes the adjusting rod 105 to drive the limiting plate 103 to move and adjust on the side plate 102 via the guide rod 106. This allows the limiting plate 103 to fix fuel tanks of different sizes, enabling the entire device to meet the impact test requirements of fuel tanks of different sizes.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
