DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application and are not used to limit the utility model.
[0029] Figure 1 This is a schematic diagram of the structure of a skirt clamping and fastening device provided by an embodiment of the utility model. Figure 1 As shown, the skirt clamping and fastening device includes a chuck component 1, a rotating shaft 2, a support seat 3 and a slide rod 4. The chuck component 1 is arranged on the support seat 3 through the rotating shaft 2, one end of the slide rod 4 is movably connected to the support seat 3, and the other end of the slide rod 4 is used to connect with the exciter. The chuck component 1 is used to clamp the skirt of the vehicle body, which avoids the weak characteristics of the vehicle body process hole in the prior art and avoids damaging the vehicle body structure. In the scheme of clamping the vehicle skirt by the chuck component 1, the relatively arranged first clamping member 11 and the second clamping member 12 have a large clamping force, strong reliability, and simple and quick installation. At the same time, when installing the chuck component 1, the installer does not need to drill into the bottom of the vehicle, which improves work efficiency, and the vehicle body excitation skirt clamping and fastening device is compatible with various different vehicle models, and the measured working condition data excitation is more accurate, which improves the reliability and quality of the test.
[0030] The clamping head component 1 includes a first clamping member 11 and a second clamping member 12 which are arranged opposite to each other. The first clamping member 11 and the second clamping member 12 are respectively arranged on the support seat 3 by rotating through the rotating shaft 2. A clamping gap is formed between the first clamping member 11 and the second clamping member 12 at one end away from the support seat 3. The clamping head fastening bolt 13 connects the first clamping member 11 and the second clamping member 12 to adjust the size of the clamping gap and clamp the skirt. The clamping head component 1 is clamped by tightening the clamping head fastening bolt 13, and the first clamping member 11 and the second clamping member 12 which are arranged opposite to each other in the clamping head component 1 are loosened and tightened by the clamping head fastening bolt 13. Among them, the clamping head fastening bolt 13 can be an external hexagonal bolt. The first clamping member 11 and the second clamping member 12 can be rotated based on the rotating shaft 2 to clamp the skirt of the vehicle. By clamping the skirt by the clamping head component 1, the installation is simple and quick, and the installer does not need to drill into the bottom of the vehicle, which can improve the work efficiency.
[0031] Furthermore, the clamping head component 1 may also include two pairs of first clamping members 11 and second clamping members 12 to form a double clamping device, which makes clamping more reliable and firm. Among them, another pair of first clamping members 11 and second clamping members 12 are also respectively rotatably arranged on the support seat 3 through the rotating shaft 2, and a clamping gap is formed between the first clamping member 11 and the second clamping member 12 at one end away from the support seat 3. The clamping head fastening bolt 13 connects the first clamping member 11 and the second clamping member 12 to adjust the size of the clamping gap and clamp the skirt.
[0032] The clamping head component 1 further includes a clamping head fixing pin 14, which axially fixes the first clamping member 11 and the second clamping member 12 to the rotating shaft 2. In this way, the clamping head fixing pin 14 fixes the first clamping member 11 and the second clamping member 12 to the rotating shaft 2, and the skirt of the clamped vehicle can rotate freely based on the rotating shaft 2, and the clamping is more free and flexible.
[0033] The support seat 3 includes a base 31. The base 31 includes a first bottom plate 311, and a first support plate 312 and a second support plate 313 are arranged on the first bottom plate 311. The first support plate 312, the second support plate 313 and the first bottom plate 311 form a first slot for fixing the clamping head component 1 to the first slot through the rotating shaft 2. Further, when there are two pairs of the first clamping member 11 and the second clamping member 12, that is, double clamping, the corresponding base 31 also includes a third support plate 314, and the second support plate 313, the third support plate 314 and the first bottom plate 311 form a second slot. In this way, the other pair of the first clamping member 11 and the second clamping member 12 in the clamping head component 1 is fixed to the second slot through the rotating shaft 2.
[0034] The support base 3 further includes a connecting bracket 32 for supporting the clamping head component 1. The connecting bracket 32 includes a top plate 321, a first bracket 322, a second bracket 323 and a second bottom plate 324, and the top plate 321 and the second bottom plate 324 are vertically fixedly connected through the first bracket 322 and the second bracket 323. In this way, the connecting bracket 32 supports the entire clamping head component 1.
[0035] The first bottom plate 311 and the top plate 321 are rigidly fixed by connecting bolts. The area of the first bottom plate 311 is equal to the area of the top plate 321. The top plate 321 can be rigidly connected by bolts along the four sides.
[0036] The area of the top plate 321 is greater than the area of the second bottom plate 324 .
[0037] The rod body of the slide bar 4 is cylindrical, and the upper end of the rod body of the slide bar 4 passes through the circular opening of the second bottom plate 324 of the support seat 3. The top of the rod body of the slide bar 4 is in a round cover shape to prevent the upper end of the slide bar 4 from sliding out of the support seat 3. A locking mechanism 5 is provided below the slide bar 4 passing through the support seat 3, which is used to fix the locking connection between the slide bar 4 and the support seat 3. In this way, the slide bar 4 can be movably connected to the support seat 3 and will not separate.
[0038] The locking mechanism 5 includes a first annular body 51 and a second annular body 52. A cylindrical rod body is provided under the second annular body 52. The first annular body 51 and the second annular body 52 are both annular and are sequentially looped around the lower end of the slide bar 4. The second annular body 52 is provided with bolts for adjusting the distance between the first annular body 51 and the second annular body 52 to control the distance between the clamping part 1 and the exciter. The connecting bracket 32 supports the entire fixture. The connecting bracket 32 can guide the slide bar 4 to move up and down through the locking mechanism 5, so that the height of the clamping part 1 can be adjusted. The connecting bracket 32 and the slide bar 4 are fastened by a screw. The lower end of the slide bar 4 is fixed on the exciter, and the exciting force of the exciter is transmitted to the clamping part 1 through the slide bar 4 and then to the vehicle body. The data iteration effect of the exciting force is increased from the original 90% to 95%, thereby improving the reliability and quality of the test.
[0039] The clamping surfaces at the top of the first clamping member 11 and the second clamping member 12 are both provided with an anti-slip structure. The anti-slip structure may be an anti-slip layer, anti-slip stripes or an anti-slip cushion layer. The anti-slip structure has the advantages of easy installation, reliable clamping, and firmness, so that the clamping head component 1 is firmly and reliably fixed, and the exciter will not loosen during the vibration process.
[0040] The embodiment of the present application provides a skirt clamping and fastening device, which reduces the whole vehicle clamping and adjustment work from the original 60 minutes of coordination and installation by two people to 30 minutes by one person, thereby improving work efficiency. The skirt of the vehicle is clamped by the first clamping member and the second clamping member of the clamping head component, and the rotating shaft movably fixes the clamping head component on the support seat. In this way, the clamping head component can be rotated based on the rotating shaft to clamp the skirt of the vehicle body, and the clamping is more flexible. The skirt is clamped by the first clamping member and the second clamping member, which avoids the various disadvantages of using the vehicle body process holes for fastening the exciter in the prior art. By not using the vehicle body process holes, the compatibility of the fastening connection device is improved and it is suitable for different vehicle models. The energy of the exciter is better transmitted to the vehicle body, making the excitation of the working condition data more accurate, and improving the reliability and quality of the test.
