Description

Technical Field

[0001] This utility model belongs to the field of aerospace fastener production technology, and specifically relates to a fastener X-ray inspection device. Background Technology

[0002] In the production of aerospace fasteners, it is necessary to inspect the fasteners using X-ray inspection equipment. While existing X-ray inspection equipment can meet the basic requirements for fastener inspection, it can only inspect one fastener at a time. After each inspection, the inspected fastener must be removed from the storage structure, and a new fastener must be placed on the structure before the next fastener can be inspected. Between each inspection, the inspection structure needs to pause for a period of time until the fastener loading and unloading are completed, thus affecting the overall efficiency of inspecting multiple fasteners.

[0003] For example, the utility model patent with announcement number CN218212718U discloses a fastener X-ray inspection device. In the technical solution of this patent document, the worker places one fastener on the carrier plate at a time, and then uses the second drive mechanism to drive the carrier plate to slide, so that the carrier plate with the fastener is slid between the X-ray machine's emitting end and the detector for inspection. After the inspection is completed, the fastener needs to be unloaded and reloaded before the fastener can continue to be inspected. Therefore, the inspection efficiency of the device is low and cannot fully meet people's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a fastener X-ray inspection device, which not only meets the basic requirements for inspecting fasteners, but also reduces the waiting time for inspected structures by batch loading and unloading fasteners, thereby improving the overall working efficiency of the device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fastener X-ray inspection device, including an inspection table, a vertical rod fixed to the top of the inspection table, a top plate fixedly connected to the vertical rod, a first telescopic push rod vertically arranged on the top plate, an X-ray shield arranged on the output shaft of the first telescopic push rod, a linear slide arranged on the top bottom wall of the X-ray shield along the left and right direction, a second telescopic push rod vertically arranged on the slide of the linear slide, a U-shaped mounting bracket arranged at the lower end of the output shaft of the second telescopic push rod along the front and back direction, an X-ray machine emitting end arranged at one end of the mounting bracket, a detector arranged at the other end of the mounting bracket, and a placement plate snapped onto the top of the inspection table, the placement plate having multiple placement grooves for snapping and fixing the lower end of the fastener.

[0006] As a further improvement of this utility model, a guide insertion hole is also provided on the top plate at the side end of the first telescopic push rod, and a guide rod that is inserted and connected to the guide insertion hole is also provided on the X-ray shield.

[0007] As a further improvement of this utility model, the linear slide table is also provided with a connecting slot on the slide base, and the top of the mounting bracket is also provided with a connecting plate that is plugged into the connecting slide groove.

[0008] As a further improvement of this utility model, the X-ray shield is made of rubber and contains a lead interlayer.

[0009] As a further improvement of this utility model, a fixing slot is provided on the testing platform for securing the placement plate. The fixing slot allows for convenient and flexible fixing of the placement plate to the testing platform.

[0010] As a further improvement of this utility model, a handle is also provided on the side of the placement plate. With the handle, workers can easily move the placement plate, thereby conveniently and flexibly fixing the placement plate to the testing table.

[0011] As a further improvement of this utility model, the bottom of the testing platform is also provided with support legs, and the bottom of the support legs is also provided with anti-slip pads. The support legs can support the testing platform; the anti-slip pads can prevent the device from easily shifting.

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

[0013] Firstly, workers can place the placement plate and multiple fasteners together on the inspection table or remove them together from the inspection table, thereby quickly and in batches loading and unloading multiple fasteners, reducing the waiting time for the inspection structure and improving the overall efficiency of inspecting multiple fasteners.

[0014] Secondly, the horizontal position of the fixture, X-ray machine transmitter, and detector can be easily adjusted by the linear slide, and the vertical position of the fixture, X-ray machine transmitter, and detector can be easily adjusted by the second telescopic push rod, thereby facilitating the inspection of multiple fasteners placed on the placement plate.

[0015] Thirdly, the connection between the guide rod and the guide hole allows the X-ray shield to move smoothly vertically and prevents the first telescopic push rod from being easily damaged by terrain changes.

[0016] Fourth, the connection between the connecting slot and the connecting plate allows the mounting bracket to move vertically smoothly and prevents the second telescopic push rod from being easily damaged by terrain deformation. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] like Figure 1 As shown, an X-ray inspection device for fasteners includes an inspection table 101, a vertical rod 102 fixed to the top of the inspection table 101, a top plate 103 fixedly connected to the vertical rod 102, a first telescopic push rod 104 vertically arranged on the top plate 103, and an X-ray shield 105 arranged on the output shaft of the first telescopic push rod 104; the X-ray shield 105 is made of rubber and contains a lead interlayer.

[0025] A linear slide 106 is installed on the top and bottom wall of the X-ray shield 105 along the left and right direction. A second telescopic push rod 107 is also vertically installed on the slide of the linear slide 106. A U-shaped mounting bracket 108 is provided at the lower end of the output shaft of the second telescopic push rod 107 along the front and back direction. An X-ray machine emitting end 109 is provided at one end of the mounting bracket 108, and a detector 110 is provided at the other end of the mounting bracket 108. A placement plate 111 is also snapped onto the top of the detection table 101. The placement plate 111 has multiple placement grooves 112 for snapping and fixing the lower end of fasteners.

[0026] The worker can snap the placement plate 111, which holds multiple fasteners, onto the testing table 101. Then, the output axis of the first telescopic push rod 104 can be driven to extend downward by a certain length, so that the X-ray shield 105 is fitted over the outside of the placement plate 111 and the multiple fasteners and abuts against the top of the testing table 101. Then, the slide of the linear slide 106 can be driven to move left and right, so that the horizontal position of the fixture, the X-ray machine transmitter 109 and the detector 110 corresponds to a fastener.

[0027] Then, the output axis of the second telescopic push rod 107 is driven to extend downward by a certain length, so that the fixing frame is fitted on the front and rear sides of a fastener, and the X-ray machine transmitter 109 and the detector 110 are respectively located at the front and rear of a fastener. Then, the X-ray machine transmitter 109 can be driven to emit X-rays, which are irradiated onto the fastener. The part of the X-rays that passes through the fastener reaches the detector 110. The vertical position of the fastener is adjusted according to the information fed back by the detector 110, thereby conveniently completing the inspection of multiple fasteners placed on the placement plate 111.

[0028] After the inspection of one fastener is completed, simply drive the slide of the linear slide 106 to move in the left and right directions, so that the fixing frame, X-ray machine transmitter 109 and detector 110 can be moved to the front and rear sides of the next fastener, and then the inspection of the next fastener can continue. After the inspection of multiple fasteners is completed in the above manner, the output axis of the first telescopic push rod 104 can be driven to shorten by a certain length, so that the protective cover can be released from the placement plate 111 and multiple fasteners. Then the placement plate 111 and multiple inspected fasteners can be removed together, and the mounting plate and the new fasteners to be inspected can be placed on the inspection table 101.

[0029] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the top plate 103 is also provided with a guide insertion hole 201 located at the side end of the first telescopic push rod 104, and the X-ray shield 105 is also fixedly connected with a guide rod 202 that is inserted into the guide insertion hole 201.

[0030] During the process of adjusting the X-ray shield 105 by extending and retracting the output shaft of the first telescopic push rod 104, the guide rod 202 can slide vertically relative to the guide hole 201, thereby enabling the X-ray shield 105 to move vertically smoothly and preventing the first telescopic push rod 104 from being easily damaged by non-vertical forces.

[0031] According to another embodiment of the present invention, such as Figure 4 As shown, the linear slide table 106 is also equipped with a connecting slot 203 on its slide base, and the top of the mounting bracket 108 is also equipped with a connecting plate 204 that is plugged into the connecting slide groove.

[0032] During the process of adjusting the height of the mounting bracket 108 by extending and retracting the output shaft of the second telescopic push rod 107, the connecting plate 204 can slide vertically relative to the connecting slot 203, and the second telescopic push rod 107 is prevented from being easily damaged by non-vertical forces.

[0033] According to another embodiment of the present invention, such as Figure 3 As shown, the fixed end of the first telescopic push rod 104 is connected to the top wall of the top plate 103, and the output shaft of the first telescopic push rod 104 passes through the top plate 103. The top of the X-ray shield 105 is provided with a first connecting cylinder 207 that is snapped and fixed to the output shaft of the first telescopic push rod 104. The first connecting cylinder 207 is provided with a first connecting bolt 208 for screwing and fixing the output shaft of the first telescopic push rod 104. The output shaft of the first telescopic push rod 104 is provided with a first threaded connection hole for screwing and connecting to the first connecting bolt 208. By simply snapping and fixing the output shaft of the first telescopic push rod 104 to the first connecting cylinder 207, and then passing the first connecting bolt 208 through the side wall of the first connecting cylinder 207 and screwing it into the first threaded connection hole, the output shaft of the first telescopic push rod 104 and the X-ray shield 105 can be flexibly fixed.

[0034] According to another embodiment of the present invention, such as Figure 4As shown, the fixed end of the second telescopic push rod 107 is connected to the bottom wall of the slide of the linear slide table 106. The top of the mounting bracket 108 is provided with a second connecting cylinder 209 that is snapped and fixed to the output shaft of the second telescopic push rod 107. The second connecting cylinder 209 is provided with a second connecting bolt 210 for screwing and fixing the output shaft of the second telescopic push rod 107. The output shaft of the second telescopic push rod 107 is provided with a second threaded connection hole for screwing and connecting to the second connecting bolt 210. By simply snapping and fixing the output shaft of the second telescopic push rod 107 to the second connecting cylinder 209, and then passing the second connecting bolt 210 through the side wall of the second connecting cylinder 209 and screwing it into the second threaded connection hole, the output shaft of the second telescopic push rod 107 can be flexibly fixed to the mounting bracket 108.

[0035] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the testing table 101 has a fixing slot 205 for engaging with the placement plate 111. The fixing slot 205 allows for easy and flexible fixing of the placement plate 111 to the testing table 101.
