Detailed Implementation

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a fastener testing device for wind power equipment, including a base 1. The upper surface of the base 1 is provided with a sliding groove, and a first sliding seat 2 is slidably connected in the sliding groove. The first sliding seat 2 and the upper surface of the base 1 are provided with a clamping assembly 3. The clamping assembly 3 is used to clamp the fastener body, which includes a bolt and a nut. The clamping assembly 3 is used to clamp and support the bolt and nut. An impact assembly 4 is provided on the upper surface of the base 1 between the clamping assemblies 3. The impact assembly 4 is used to impact the fastener body. After the clamping assembly 3 clamps the bolt and nut, the impact assembly 4 abuts against one side of the nut to impact the nut. The installation condition between the nut and the bolt, as well as the strength of the threads on the bolt and nut, are tested, thereby testing the fastening performance of the fastener body and improving the safety of the fastener body in use.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the clamping assembly 3 includes a first fixing plate 31, which is fixedly connected to the base 1. A second fixing plate 32 is fixedly connected to the upper surface of the first sliding seat 2. A guide rod 33 is fixedly connected to one side of the second fixing plate 32. A third fixing plate 34 is slidably connected to the guide rod 33, passing through the third fixing plate 34. The third fixing plate 34 is located between the first fixing plate 31 and the second fixing plate 32. A fixing ring 35 is fixedly connected to the upper surfaces of the first fixing plate 31, the second fixing plate 32, and the third fixing plate 34. When fixing the fastener body, the nut is placed between the second fixing plate 32 and the third fixing plate 34, and the bolt is pulled from the first fixing plate 31 to the third fixing plate 34. The fixing plate 31 passes through, and the bolt passes through the second fixing plate 32 and the third fixing plate 34. The nut is installed on the bolt. At this time, the third fixing plate 34 is pushed so that the third fixing plate 34 and the second fixing plate 32 abut against the two sides of the nut. The impact component 4 is located between the first fixing plate 31 and the third fixing plate 34. The impact component 4 impacts the third fixing plate 34. The impact force is transmitted to the nut through the third fixing plate 34, and then to the threads on the nut and the bolt. The impact groove is tested to simulate the installation state of the bolt and nut, as well as the pressure on the bolt and nut when the wind power equipment is operating. The bolt and nut are tested.

[0026] like Figure 1 As shown, the first threaded rod 5 is rotatably connected to one side of the second fixing plate 32. The first threaded rod 5 passes through the third fixing plate 34 and is threadedly connected to the third fixing plate 34. When the nut and bolt are installed, the first sliding seat 2 slides, and the fixing ring 35 on the second fixing plate 32 abuts against one side of the nut. Rotating the first threaded rod 5 causes the fixing ring 35 on the third fixing plate 34 to press against the other side of the nut. The bolt is fixed by the fixing ring 35 on the first fixing plate 31, and the nut is fixed by the fixing rings 35 on the second fixing plate 32 and the third fixing plate 34. However, the second fixing plate 32 and the third fixing plate 34 can slide on the first sliding seat 2. When the impact component 4 impacts the third fixing plate 34, most of the impact force can be transferred to the nut, improving the accuracy of the detection.

[0027] like Figure 2As shown, the impact assembly 4 includes a second sliding seat 41 located within a groove and slidably connected to the base 1. A housing 42 is fixedly connected to the upper surface of the second sliding seat 41, and a support plate 43 is fixedly connected inside the housing 42. A drive motor 44 is fixedly connected to the lower surface of the support plate 43. The main shaft of the drive motor 44 is fixedly connected to a circular plate 45. The connection position between the drive motor 44's main shaft and the circular plate 45 is offset from the center of the circular plate 45. When the drive motor 44 drives the circular plate 45 to rotate, the side of the circular plate 45 pushes the sliding cylinder 46 to slide, causing the sliding cylinder 46 to impact the third fixed plate 34, thereby impacting the nut. One rotation of the drive motor 44 impacts the third fixed plate 34 once, thus impacting the nut. The fixed plate 34 is subjected to continuous impact for sustained testing. The side wall of the housing 42 is slidably connected to the sliding cylinder 46, which penetrates the housing 42. Two support plates 47 are fixedly connected to the outer side of the sliding cylinder 46, and two crossbars 48 are fixedly connected to the inner wall of the housing 42. The crossbars 48 penetrate the support plates 47 and are slidably connected to them. A second spring 49 is fixedly connected between the inner wall of the housing 42 and the support plates 47. An arc-shaped block is fixedly connected to one side of the sliding cylinder 46. When the circular plate 45 is at its furthest point from the drive motor 44 and contacts the sliding cylinder 46, it impacts the third fixed plate 34 once. When the circular plate 45 rotates and disengages from the sliding cylinder 46 at its furthest point from the drive motor 44, the sliding cylinder 46 resets under the action of the second spring 49, facilitating continuous testing.

[0028] like Figure 2 As shown, a sliding rod 6 is slidably connected inside the sliding cylinder 46, and a first spring 7 is fixedly connected between the sliding rod 6 and the sliding cylinder 46. One end of the sliding rod 6 is fixedly connected to a contact plate 8. When the sliding cylinder 46 is pushed by the circular plate 45, the sliding cylinder 46 slides, and the contact plate 8 at one end of the sliding rod 6 is always in contact with the third fixed plate 34. The first spring 7 is compressed, and through the reaction force of the first spring 7, the sliding rod 6 impacts the third fixed plate 34. The sliding rod 6 slides inside the sliding cylinder 46, and the first spring 7 is compressed. There is a certain buffer between the sliding cylinder 46 and the sliding rod 6 that impacts the third fixed plate 34, so as to avoid the circular block pushing the sliding cylinder 46 to hit the third fixed plate 34. Due to the obstruction of the third fixed plate 34, an impact occurs between the circular block and the sliding cylinder 46, causing the sliding cylinder 46 to deform.

[0029] like Figure 3 and Figure 4 As shown, a second threaded rod 9 is threadedly connected to the first fixed plate 31. The second threaded rod 9 passes through the first fixed plate 31 and is rotatably connected to the housing 42. The second threaded rod 9 is used to control the distance between the housing 42 and the third fixed plate 34. The first sliding seat 2 and the first threaded rod 5 are used to adjust the position of the second fixed plate 32 and the third fixed plate 34, so that the device can detect bolts of different lengths.

[0030] like Figure 1 and Figure 2 As shown, a horizontal plate 10 is fixedly connected to one side of the second fixing plate 32, and a vertical plate 11 is fixedly connected to the upper surface of the base 1. The horizontal plate 10 passes through the vertical plate 11, and a mounting plate 12 is fixedly connected to one side of the vertical plate 11. The mounting plate 12 has a circular through groove, and a rubber sleeve is fixedly connected in the circular through groove. A marker pen 13 is placed in the rubber sleeve. A white plastic plate 14 is provided on the upper surface of the horizontal plate 10. When the bolt and nut are fixed, the contact plate 8 contacts the third fixing plate 34. At this time, the marker pen 13 is pushed down so that the tip of the marker pen 13 touches the white plastic plate 14 on the horizontal plate 10. When it impacts the third fixing plate 34, it impacts the nut. When the nut falls off or loosens, the nut, the first sliding seat 2, the second fixing plate 32 and the third fixing plate 34 move together, and the horizontal plate 10 moves accordingly. The marker pen 13 leaves a scratch mark on the white plastic plate 14, which is convenient for measuring the distance the nut moves.

[0031] Working principle: The nut is placed between the second fixing plate 32 and the third fixing plate 34. The bolt passes through the first fixing plate 31, and then through the second fixing plate 32 and the third fixing plate 34. The nut is installed on the bolt. The fixing ring 35 on the second fixing plate 32 abuts against one side of the nut. The first threaded rod 5 is rotated, so that the fixing ring 35 on the third fixing plate 34 is pressed against the other side of the nut. The bolt is fixed by the fixing ring 35 on the first fixing plate 31. The second threaded rod 9 is rotated, and the contact plate 8 at one end of the sliding rod 6 is always in contact with the third fixing plate 34. The drive motor 44 drives the circular plate 45 to rotate, pushing the sliding cylinder 46 to slide. The first spring 7 is compressed, impacting the third fixing plate 34. When the nut falls off or loosens, the nut, the first sliding seat 2, the second fixing plate 32 and the third fixing plate 34 move together, and the horizontal plate 10 moves accordingly. The marker pen 13 leaves scratch marks on the white plastic plate 14.
