Description

Technical Field

[0001] This utility model belongs to the field of aerospace fastener technology, and specifically relates to an anti-loosening test device. Background Technology

[0002] Aerospace fasteners require high-frequency vibration testing during production to simulate aircraft operation and assess their anti-loosening performance. While existing anti-loosening testing equipment can meet the basic requirements for testing bolts and nuts, the fasteners are typically directly exposed to the external environment during testing. This can lead to some fasteners detaching and flying off, posing a significant safety hazard and thus failing to fully meet user needs.

[0003] For example, the utility model patent with announcement number CN222049500U discloses an anti-loosening test device for aerospace standard parts. In the technical solution of this patent document, multiple fasteners are installed on the test seat. During the operation of the device, the test seat and fasteners are directly exposed to the outside, which may cause some loose fasteners to fall off the test seat and fly away, thereby causing damage to surrounding objects or people, and thus causing great inconvenience to people's use. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an anti-loosening test device, which not only meets the basic requirements for testing fasteners against loosening, but also prevents the fasteners being tested from breaking off due to insufficient anti-loosening performance, thereby improving the safety of the device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an anti-loosening test device, including a test platform, an anti-loosening test module is provided on the test platform, a telescopic push rod is vertically provided on the test platform, a top plate is provided on the output shaft of the telescopic push rod, a guide tube is provided on the test platform, a guide rod is provided at the bottom of the top plate and is connected to the guide tube, and a protective cover is provided at the bottom of the top plate to cover the anti-loosening test module.

[0006] As a further improvement of this utility model, the anti-loosening detection module includes a linear slide table set on the detection table. A fixed plate that slides and connects to the detection table is provided on the slide base of the linear slide table. Multiple springs are vertically arranged on the mounting plate. A mounting bracket is provided at the upper end of the multiple springs. A connecting sleeve is also provided on the mounting plate. A connecting plate that is plugged into and connected to the connecting sleeve is provided at the bottom of the mounting bracket. A vibration motor is provided on the mounting bracket. A mounting shaft is rotatably arranged on the mounting bracket. A drive module for driving the rotation of the mounting shaft is provided on the mounting bracket. A mounting plate for mounting fasteners is provided on the mounting shaft. Multiple mounting holes for fasteners to pass through are provided on the mounting plate.

[0007] As a further improvement of this utility model, the testing platform is provided with a connecting groove parallel to the running direction of the linear slide table, and the bottom of the fixed plate is provided with a connecting slider that is slidably connected to the connecting groove. The vertical cross-section of both the connecting groove and the connecting slider is T-shaped. Through the sliding cooperation of the connecting groove and the connecting slider, the fixed plate can be assisted in sliding. Because the vertical cross-section of both the connecting groove and the connecting slider is T-shaped, vertical displacement of the connecting slider relative to the connecting groove can be avoided, thereby improving the stability of the device.

[0008] As a further improvement of this utility model, the mounting bracket is U-shaped and has two mounting shafts, which are respectively transversely connected and rotatably mounted on the side end of the mounting bracket.

[0009] As a further improvement of this utility model, the drive module includes a drive motor horizontally disposed on one side of the mounting bracket, a drive gear disposed on the drive motor, and a driven gear meshing with the drive gear disposed near the output shaft of the drive motor. Through the cooperation of the drive motor, the drive gear, and the driven gear, the mounting shaft and the mounting plate can be rotated.

[0010] As a further improvement of this invention, a transparent observation window is also provided on the protective cover. Through the transparent observation window, workers can easily observe the situation inside the protective cover.

[0011] As a further improvement of this utility model, the bottom of the testing platform is provided with support legs, and the side ends of the support legs are also provided with extension plates, on which anchor bolts for connecting to the ground are provided. The support legs can support the device, making it easier for workers to use the device; the extension plates and anchor bolts can prevent the device from easily shifting during operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, workers can open the protective cover, install the fasteners onto the anti-loosening detection module, and then place the protective cover over the outside of the anti-loosening detection module and press it against the detection table. This effectively prevents some fasteners from flying off due to insufficient anti-loosening performance during the loosening test, thereby improving the safety of the device.

[0014] Secondly, users only need to pass the bolt through the mounting hole and connect it with the nut to fix the fastener to the mounting plate. Then, the mounting plate and fastener can be translated by the linear slide, vertically vibrated by the vibration motor and spring, and rotated by the drive module and mounting shaft, thereby simulating the high-frequency oscillation test of the fastener by aircraft operation.

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 3 As shown, an anti-loosening test device includes a test platform 101, an anti-loosening detection module is provided on the test platform 101, a telescopic push rod 102 is vertically installed on the test platform 101, a top plate 103 is installed on the output shaft of the telescopic push rod 102, a guide tube 104 is fixed on the test platform 101, a guide rod 105 that is inserted and connected to the guide tube 104 is fixed at the bottom of the top plate 103, and a protective cover 106 that can cover the anti-loosening detection module is provided at the bottom of the top plate 103.

[0023] The worker can first drive the output axis of the telescopic push rod 102 to extend upward by a certain length, causing the protective cover 106 to move upward and remove the cover from the anti-loosening detection module. Then, the fastener to be tested can be installed on the anti-loosening detection module. Subsequently, the output axis of the telescopic push rod 102 is driven downward to shorten by a certain length, causing the protective cover 106 to be re-covered on the outside of the anti-loosening detection module and abut against the detection table 101. After that, the fastener can be loosened and tested, thereby effectively preventing some fasteners from breaking off due to insufficient anti-loosening performance during the loosening and loosening test, thus improving the safety of the device.

[0024] During the process of raising and lowering the protective cover 106 by adjusting the telescopic push rod 102, the outgoing insertion rod will be vertically connected relative to the guide tube 104, thereby guiding the vertical movement of the top plate 103 and the protective cover 106, so that the top plate 103 and the protective cover 106 move vertically smoothly and avoid the telescopic push rod 102 from being easily damaged by terrain deformation.

[0025] According to another embodiment of the present invention, such as Figure 2 As shown, the anti-loosening detection module includes a linear slide 201 mounted on a detection table 101. A fixed plate 202 is mounted on the slide of the linear slide 201 and is slidably connected to the detection table 101. Multiple springs 203 are vertically mounted on a mounting plate 209. A mounting bracket 204 is mounted on the upper end of the multiple springs 203. A connecting sleeve 205 is also mounted on the mounting plate 209. A connecting plate 206 is mounted at the bottom of the mounting bracket 204 and is inserted into the connecting sleeve 205. A vibration motor 207 is mounted on the mounting bracket 204. A mounting shaft 208 is rotatably mounted on the mounting bracket 204. A drive module for rotating the mounting shaft 208 is mounted on the mounting bracket 204. A mounting plate 209 for mounting fasteners is mounted on the mounting shaft 208. Multiple mounting holes 210 are provided on the mounting plate 209 for fasteners to pass through.

[0026] The testing table 101 is provided with a connecting groove 211 parallel to the running direction of the linear slide table 201. The bottom of the fixed plate 202 is provided with a connecting slider 212 that is slidably connected to the connecting groove 211. Both the connecting groove 211 and the connecting slider 212 have T-shaped vertical cross-sections. Through the sliding engagement of the connecting groove 211 and the connecting slider 212, the fixed plate 202 can be assisted in its sliding movement. Because both the connecting groove 211 and the connecting slider 212 have T-shaped vertical cross-sections, vertical displacement of the connecting slider 212 relative to the connecting groove 211 can be avoided, thereby improving the stability of the device.

[0027] After the fasteners are installed and the protective cover 106 is installed, the slide block of the linear slide table 201 can be driven to move left and right. Under the guidance of the connecting slide groove 211 and the connecting slider 212, the mounting plate 209 and the fasteners are translated. The vibration motor 207 can be started, and under the guidance of multiple springs 203 and the connection between the connecting insert plate 206 and the connecting insert 205, the mounting plate 209 and the fasteners are driven to vibrate vertically. The mounting plate 209 and the fasteners can also be rotated through the drive module and the mounting shaft 208, thereby simulating the high-frequency oscillation test of the fasteners during aircraft operation.

[0028] According to another embodiment of the present invention, such as Figure 2 As shown, the mounting bracket 204 is U-shaped, and there are two mounting shafts 208. The two mounting shafts 208 are transversely connected and rotatably mounted on the side end of the mounting bracket 204. Bearings 213 are respectively provided on both sides of the mounting bracket 204. The outer ring of the bearing 213 is connected to the side wall of the mounting bracket 204, and the inner ring of the bearing 213 is connected to the outer wall of the mounting shaft 208.

[0029] The drive module includes a drive motor 301 that is horizontally arranged on one side of the mounting bracket 204. The drive motor 301 is provided with a drive gear 302, and a driven gear 303 that meshes with the drive gear 302 is provided on the output shaft of the drive motor 301.

[0030] The worker only needs to start the drive motor 301, and the mounting shaft 208 and mounting plate 209 can be rotated through the transmission action of the drive gear 302 and the driven gear 303.

[0031] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a transparent observation window 107 is also provided on the protective cover 106. Through the transparent observation window 107, workers can easily observe the inside of the protective cover 106 to understand the experimental status of the fasteners.

[0032] According to another embodiment of the present invention, such as Figure 3 As shown, the bottom of the testing platform 101 is provided with a support leg 108, and the side end of the support leg 108 is also provided with an extension plate 109. Anchor bolts 110 for connecting to the ground are provided on the extension plate 109. The support leg 108 can support the device, making it easier for workers to use the device; workers can pass the anchor bolts 110 through the extension plate 109 and connect them to the ground, thereby preventing the device from easily shifting during operation.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
