Description

Technical Field

[0001] The present application belongs to the technical field of automobile parts cleanliness detection, and more specifically, to a particle cleanliness shaking test device. Background Art

[0002] At present, when conducting particle contamination detection on automobile function-related parts based on the shaking cleaning method, it is necessary to first pour the cleaning liquid into the inner cavity of the test sample, and then continue to shake the test sample after the test sample is sealed, so that the impurities on the inner cavity wall of the test sample gradually fall off into the cleaning liquid in an agitated state. Finally, the test sample is opened and the cleaning liquid is discharged, and the impurities therein are filtered and collected, so as to observe and record information such as the particle composition, quantity and specifications.

[0003] However, in the above-mentioned detection process, most of the test samples are manually shaken by manual operation. When the size of the test sample is large (for example, the length exceeds 30cm, or the weight exceeds 10kg), the manual shaking of the test sample is time-consuming and labor-intensive, and sometimes even requires the cooperation of multiple people to complete the detection, which affects the detection efficiency.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0035] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0036] Please refer to Figure 1 and Figure 2 . Now, a particle cleanliness shaking test device 10 provided in an embodiment of the present application will be described. The above-mentioned particle cleanliness shaking test device 10 includes a fixed support bracket 100, a first movable bracket 200, a second movable bracket 300, and a bracket connection rotating shaft 400. The particle cleanliness shaking test device 10 further includes a rotating shaft locking assembly (not shown in the figure). Among them, the first movable bracket 200 has a first fixed area 201, the second movable bracket 300 has a second fixed area 301. The first movable bracket 200 is rotationally connected to the fixed support bracket 100 through the bracket connection rotating shaft 400 and rotates along the self-rotation direction of the bracket connection rotating shaft 400. The rotating shaft locking assembly is used to lock or unlock the rotation of the bracket connection rotating shaft 400. The first movable bracket 200 and the second movable bracket 300 are hingedly movably connected. In this way, by relatively rotating the first movable bracket 200 and the second movable bracket 300 around the hinge, the first movable bracket 200 and the second movable bracket 300 can be relatively unfolded, and further the first fixed area 201 and the second fixed area 301 are connected to form a sample fixing area 600 for supporting and fixing a test sample (not shown in the figure), or the first movable bracket 200 and the second movable bracket 300 can be relatively folded, and further the first fixed area 201 and the second fixed area 301 are separated to release the sample fixing area 600.

[0037] The beneficial effect of the particle cleanliness shaking test device 10 provided by this application is that, compared with the prior art, the above-mentioned particle cleanliness shaking test device 10 includes a fixed support bracket 100, a first movable bracket 200 with a first fixed area 201, a second movable bracket 300 with a second fixed area 301, and a bracket connection rotating shaft 400. Among them, the first movable bracket 200 is movably connected to the fixed support bracket 100 through the bracket connection rotating shaft 400, and the first movable bracket 200 and the second movable bracket 300 are hingedly movably connected. In this way, during the relevant detection process, by relatively rotating the first movable bracket 200 and the second movable bracket 300 around the hinge, the first movable bracket 200 and the second movable bracket 300 are relatively unfolded, so that the first fixed area 201 and the second fixed area 301 are connected to form a sample fixing area 600. Then, after supporting and fixing the test sample in the sample fixing area 600, the first movable bracket 200 and the second movable bracket 300 are synchronously flipped through the bracket connection rotating shaft 400, so as to shake the test sample located in the sample fixing area 600. It can be seen that the above test process avoids manually shaking the test sample by manual operation, effectively improving the detection efficiency. Moreover, after the relevant detection is completed, by relatively rotating the first movable bracket 200 and the second movable bracket 300 around the hinge, the first movable bracket 200 and the second movable bracket 300 are relatively folded, so that the first fixed area 201 and the second fixed area 301 are separated to release the sample fixing area 600, thereby reducing the floor space size of the particle cleanliness shaking test device 10, which is effectively beneficial to the storage and transportation of the particle cleanliness shaking test device 10.

[0038] Further, in this embodiment, when the first movable bracket 200 and the second movable bracket 300 are relatively unfolded so that the first fixed area 201 and the second fixed area 301 are connected to form a sample fixing area 600, the length extension direction of the sample fixing area 600 is parallel to the first direction, the width extension direction of the sample fixing area 600 is parallel to the second direction, the height extension direction of the sample fixing area 600 is parallel to the third direction, and the axial direction of the bracket connection rotating shaft 400 is parallel to the second direction. Among them, the first direction is parallel to the arrangement direction of the first fixed area 201 and the second fixed area 301 in the sample fixing area 600, the second direction is perpendicular to the arrangement direction of the first fixed area 201 and the second fixed area 301 in the sample fixing area 600, and the third direction is perpendicular to the first direction and the second direction respectively.

[0039] It can be understood that in this embodiment, the above-mentioned first direction, second direction, and third direction all change in real time based on the synchronous flipping angle of the first movable bracket 200 and the second movable bracket 300. However, the first direction is always parallel to the arrangement direction of the first fixing area 201 and the second fixing area 301 in the sample fixing area 600, the second direction is always perpendicular to the arrangement direction of the first fixing area 201 and the second fixing area 301 in the sample fixing area 600, and the third direction is always perpendicular to the first direction and the second direction respectively.

[0040] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , in this embodiment, the above-mentioned first movable bracket 200 includes a first support platform 210 and a first adjustment fence 220 arranged on a part of the edge of the first support platform 210. The first support platform 210 and the first adjustment fence 220 cooperate to enclose a first fixing area 201. The second movable bracket 300 includes a second support platform 310 and a second adjustment fence 320 arranged on a part of the edge of the second support platform 310. The second support platform 310 and the second adjustment fence 320 cooperate to enclose a second fixing area 301, and taking the perspectives in Figure 4 and Figure 6 as examples, one side of the bottom of the first support platform 210 adjacent to the second support platform 310 is rotationally connected to the fixed support bracket 100 through a bracket connection rotating shaft 400. One side of the edge of the first support platform 210 adjacent to the second support platform 310 is hinge-connected to one side of the edge of the second support platform 310 adjacent to the first support platform 210. When the first movable bracket 200 and the second movable bracket 300 are in a relatively unfolded state, the corresponding first support platform 210 and the second support platform 310 are relatively connected and communicated. When the first movable bracket 200 and the second movable bracket 300 are in a relatively folded state, the corresponding first support platform 210 and the second support platform 310 are respectively inclined downward and relatively separated.

[0041] Furthermore, in this embodiment, the above-mentioned particle cleanliness shaking test device 10 further includes a bracket locking assembly 500. The bracket locking assembly 500 is used to lock the first support platform 210 and the second support platform 310 when the first support platform 210 and the second support platform 310 are relatively connected and communicated, so that the first support platform 210 and the second support platform 310 remain relatively fixed during the synchronous flipping process through the bracket connection rotating shaft 400.

[0042] Specifically, in this embodiment, the above-mentioned bracket locking assembly 500 includes a first bracket locking portion 510 and a second bracket locking portion 520. Among them, the first bracket locking portions 510 are arranged in pairs along the second direction on opposite sides of the edge of the first support platform 210, and the second bracket locking portions 520 are arranged in pairs along the second direction on opposite sides of the edge of the second support platform 310. Each first bracket locking portion 510 and each second bracket locking portion 520 are used for fixedly connecting in one-to-one correspondence when the first support platform 210 and the second support platform 310 are relatively connected and communicated with each other.

[0043] More specifically, in this embodiment, the above-mentioned first bracket locking portion 510 includes a connecting cantilever. The connecting cantilevers of each first bracket locking portion 510 are respectively arranged on opposite sides of the edge of the first support platform 210 along the second direction, and respectively extend along the side facing the second support platform 310 in the first reverse direction. A first connecting pin hole is provided at one end of each connecting cantilever adjacent to the second support platform 310. The second bracket locking portion 520 includes a second connecting pin hole and a locking connecting pin shaft. The second connecting pin holes of each second bracket locking portion 520 are respectively arranged on opposite sides of the edge of the second support platform 310 along the second direction. And when the first support platform 210 and the second support platform 310 are relatively connected and communicated with each other, the locking pin shafts respectively pass through the corresponding first pin holes and the corresponding second pin holes in sequence along the second direction to lock the first support platform 210 and the second support platform 310. The above-mentioned locking structure is relatively simple and easy to operate, which is beneficial to the quick locking and unlocking of the first support platform 210 and the second support platform 310.

[0044] Please refer to Figure 3 and Figure 4 , in this embodiment, the above-mentioned first support platform 210 is provided with a first avoidance through groove 211. The first avoidance through groove 211 avoids the first adjustment fence 220 along the third direction and extends through opposite sides of the edge of the first support platform 210 along the second direction. The second support platform 310 is provided with a second avoidance through groove 311. The second avoidance through groove 311 avoids the second adjustment fence 320 along the third direction and extends through opposite sides of the edge of the second support platform 310 along the second direction.

[0045] It should be noted that, in this embodiment, the functions of the above-mentioned first avoidance through groove 211 and the second avoidance through groove 311 are to facilitate the picking and placing of test samples by a forklift (not shown in the figure). Specifically, when it is necessary to place the test sample into the sample fixing area 600, it is necessary to relatively connect and communicate the first support platform 210 and the second support platform 310, lock the first support platform 210 and the second support platform 310 through the bracket locking assembly 500, and then synchronously flip the first support platform 210 and the second support platform 310 through the bracket connecting rotating shaft 400, so that the first support platform 210 and the second support platform 310 are in the shape ofFigure 4 In the horizontal setting as shown, then the test sample is placed downward along the third direction into the sample fixing area 600 by a forklift. During the above operation process, the cantilevers of the forklift used to support the test sample respectively fall into the first avoidance through groove 211 and the second avoidance through groove 311 after passing through the sample fixing area 600 along the third direction. And when the test sample is completely placed in the sample fixing area 600, the cantilevers of the forklift used to support the test sample respectively leave the first avoidance through groove 211 and the second avoidance through groove 311 along the second direction. When it is necessary to take out the test sample from the sample fixing area 600, the cantilevers of the forklift used to support the test sample are respectively extended into the first avoidance through groove 211 and the second avoidance through groove 311 along the second direction, and then the test sample can be taken out upward along the third direction.

[0046] Further, in this embodiment, the first adjustment fence 220 includes a first fence unit 230 and a second fence unit 240, and the second adjustment fence 320 includes a third fence unit 330 and a fourth fence unit 340. Among them, the first fence unit 230 is arranged along the first direction on the side of the edge of the first support platform 210 far from the second support platform 310, and the third fence unit 330 is arranged along the first direction on the side of the edge of the second support platform 310 far from the first support platform 210. And the first fence unit 230 and the third fence unit 330 are relatively movable along the first direction, so as to adjust the length dimension of the sample fixing area 600. The second fence unit 240 is arranged in pairs along the second direction on the opposite sides of the edge of the first support platform 210, and the paired second fence units 240 are relatively movable along the second direction. The fourth fence unit 340 is arranged in pairs along the second direction on the opposite sides of the edge of the second support platform 310, and the paired fourth fence units 340 are relatively movable along the second direction, so as to cooperate to adjust the width dimension of the sample fixing area 600.

[0047] Further, in the present embodiment, the second fence unit 240 includes a second fence fixing portion 241, a second fence flipping portion 242, and a second fence locking assembly 243. Among them, the second fence fixing portions 241 of each second fence unit 240 are arranged in pairs on opposite sides of the edge of the first support platform 210 along the second direction. The second fence fixing portions 241 of the paired second fence units 240 are relatively movable along the second direction and avoid the test samples located in the sample fixing area 600 along the second direction. And the second fence fixing portion 241 of each second fence unit 240 is hinge-connected to the corresponding second fence flipping portion 242, so that the second fence flipping portions 242 of each second fence unit 240 are used to limit the test samples located in the sample fixing area 600 along the second direction respectively, or avoid the test samples located in the sample fixing area 600 along the second direction respectively. The second fence locking assembly 243 is used to lock and connect the corresponding second fence fixing portion 241 and the second fence flipping portion 242 when the second fence flipping portion 242 limits the test samples located in the sample fixing area 600 along the second direction, so that the corresponding second fence fixing portion 241 and the second fence flipping portion 242 are kept fixed.

[0048] Further, in the present embodiment, the fourth fence unit 340 includes a fourth fence fixing portion 341, a fourth fence flipping portion 342, and a fourth fence locking assembly 343. The fourth fence fixing portions 341 of each fourth fence unit 340 are arranged in pairs on opposite sides of the edge of the second support platform 310 along the second direction.
