[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 4 The transducer vibration test fixing structure in this embodiment includes a vibration plate 1 and a fixing plate 2 fixedly connected to the top side of the vibration plate 1. The vibration plate 1 is provided with a clamping assembly, which includes two positioning plates 3 fixedly installed on the top of the vibration plate 1 and two adjusting plates 4 movably installed on the top of the vibration plate 1.
[0027] In this embodiment, adjustment components are provided on the outer sides of both adjustment plates 4. The adjustment components include a mounting plate 5 fixedly installed on the top of the vibration plate 1, an adjustment screw 6 threadedly connected to the inner side of the mounting plate 5, one end of the adjustment screw 6 being rotatably connected to the outer wall of the adjustment plate 4, and a handle 7 fixedly connected to the other end of the adjustment screw 6.
[0028] The adjusting screw 6 is fixedly connected to a connecting shaft 10 at one end near the adjusting plate 4. A bearing 11 is fixedly installed on the adjusting plate 4 near the connecting shaft 10. The inner ring of the connecting shaft 10 and the bearing 11 is interference-fitted. The cooperation between the bearing 11 and the connecting shaft 10 provides rotational support for the adjusting screw 6, preventing the adjusting plate 4 from interfering with the rotation of the adjusting screw 6. A slider 8 is fixedly connected to the bottom of the adjusting plate 4. A groove 9 is opened on the surface of the vibrating plate 1. The slider 8 slides in the inner side of the groove 9. The cooperation between the slider 8 and the groove 9 guides the adjusting plate 4, enabling the adjusting plate 4 to maintain a stable movement trajectory and improving the stability of the structure.
[0029] In this embodiment, a clamping assembly is provided on the outer side of the fixing plate 2. The clamping assembly includes a top plate 12 fixedly connected to the upper part of the fixing plate 2. A hydraulic rod 13 is fixedly installed on the top of the top plate 12. A clamping plate 14 is fixedly installed on the output shaft of the hydraulic rod 13. A guide rod 15 extending through to the upper side of the top plate 12 is fixedly connected to the top of the clamping plate 14. The outer wall of the guide rod 15 slides with the inner side of the top plate 12. There are two guide rods 15, which are symmetrically distributed on both sides of the hydraulic rod 13. The height of the clamping plate 14 can be adjusted by driving the hydraulic rod 13. The guide rod 15 guides the clamping plate 14, which improves the stability of the structure.
[0030] It should be noted that rubber pads 16 are fixedly connected to the opposite surfaces of the positioning plate 3, the adjusting plate 4 and the clamping plate 14. The rubber pads 16 play a buffering and protective role, thus protecting the converter.
[0031] It should be noted that the two positioning plates 3 are distributed at an angle on the top of the vibration plate 1, and the two adjusting plates 4 are distributed at an angle on the top of the vibration plate 1. The two adjusting plates 4 correspond to the two positioning plates 3 respectively. By setting the two positioning plates 3 and the two adjusting plates 4 to correspond to the four sides of the converter respectively, it is convenient to clamp the converter. At the same time, the clamping plate 14 is located at the bottom of the top plate 12 and is positioned above the two positioning plates 3 and the two adjusting plates 4. The clamping plate 14 can press the top of the converter, improving the fixing effect.
[0032] The working principle of the above embodiments is as follows:
[0033] In use, the converter to be tested is placed between two positioning plates 3 and two adjusting plates 4. Two adjacent sides of the converter are engaged with the two positioning plates 3. By rotating the handle 7, the adjusting screw 6 is rotated and moved, which pushes the adjusting plates 4 to move, so that the two adjusting plates 4 can engage with the other two adjacent sides of the converter to clamp the converter. In addition, by activating the hydraulic rod 13, the clamping plate 14 is moved downward, so that the clamping plate 14 is engaged with the top of the converter to reinforce the converter. In subsequent testing, the adjusting plates 4 and clamping plates 14 can be adjusted to the appropriate positions according to the size of the converter to install and fix converters of different sizes.
[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. It should be noted that the orientation or positional relationship indicated herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
