Detailed implementation manner

[0042] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. Among them, the accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0043] Please refer to Figures 1 to 3 , this vibration exciter mounting device 100 includes a base 1, a tray 3 and a lifting structure 4; a lifting platform 2 is provided at intervals on the upper side of the base 1, the lifting platform 2 is movably arranged in the up and down direction and is provided with an adjusting part 21; the tray 3 is provided with a fixing part 31, and the fixing part 31 is used to cooperate with the matching part provided on the vibration exciter 200, so that the vibration exciter 200 is fixed on the tray 3 and the fixed angle between the vibration exciter 200 and the tray 3 can be adjusted. Moreover, the tray 3 is further provided with a mounting part 32 corresponding to the adjusting part 21, and the mounting part 32 cooperates with the adjusting part 21 to fix the tray 3 on the lifting platform 2 and make the rotation angle of the tray 3 around the up and down axis adjustable when the tray 3 is fixed on the lifting platform 2; the lifting structure 4 is arranged on the base 1 and is drivingly connected to the lifting platform 2 to drive the lifting platform 2 to move.

[0044] For the vibration exciter mounting device 100 provided by the present invention, when a test needs to be carried out, the fixed angle between the vibration exciter 200 and the tray 3 can be adjusted through the fixing part 31. At the same time, the rotation angle of the tray 3 in the circumferential direction can be adjusted by the cooperation of the mounting part 32 and the adjusting part 21, that is, the rotation angle of the vibration exciter 200 can be adjusted, so that the angle adjustment of the vibration exciter 200 is more flexible; it can also adjust the height of the lifting platform 2 through the lifting structure 4, and then the height of the vibration exciter 200 can be correspondingly adjusted to adapt to the vibration test points at different height positions. In this way, with the help of this vibration exciter mounting device 100, the angle and height of the vibration exciter 200 can be adjusted conveniently and flexibly, so that objects at different angles and heights can be tested, improving the practicability.

[0045] It should be noted that in the attached drawing examples, the up - down direction, the width direction and the length direction of the lifting platform 2 are respectively shown as F1, F2 and F3.

[0046] Furthermore, the adjusting part 21 is a plurality of adjusting holes 21a penetrating through the lifting platform 2 in the up - down direction. The plurality of adjusting holes 21a are arranged at circumferential intervals. The tray 3 is provided with a plurality of mounting holes 3a corresponding to the adjusting holes 21a; the mounting part 32 is a plurality of mounting screw - connectors 321 arranged corresponding to the plurality of mounting holes 3a. Each mounting screw - connector 321 is detachably passed through the corresponding mounting hole 3a and adjusting hole 21a, so that the rotation angle of the tray 3 around the up - down axis can be adjusted when the tray 3 is fixed to the lifting platform 2.

[0047] In this embodiment, both the plurality of adjusting holes 21a and the plurality of mounting holes 3a are arranged at circumferential intervals. Thus, when it is necessary to adjust the rotation angle of the vibrator 200, the tray 3 is rotated by a certain angle. At this time, the plurality of mounting holes 3a and the plurality of adjusting holes 21a can still correspond, and the tray 3 and the lifting platform 2 are fixed by the mounting screw - connectors 321. This solution realizes the adjustment of the rotation angle of the vibrator 200 through the cooperation of the adjusting holes 21a, the mounting holes 3a and the mounting screw - connectors 321, with a simple and reliable structure and convenient operation.

[0048] Furthermore, the tray 3 includes a mounting table 33 and a rotating table 34 detachably connected in the up - down direction; among them, the mounting holes 3a are arranged on the rotating table 34, so that the rotating table 34 is detachably fixed to the lifting platform 2, and the fixing part 31 is arranged on the mounting table 33. In this embodiment, the rotating table 34 can be first fixed to the lifting platform 2 at the rotation angle corresponding to the test piece to be tested. After the rotating table 34 is fixed, the mounting table 33 provided with the vibrator 200 is then fixed on the rotating table 34, so as to avoid the operator having to carry the vibrator 200 to adjust the rotation angle together, which increases the working intensity and makes the adjustment of the rotation angle more convenient.

[0049] Specifically, the rotating table 34 is provided with a plurality of screw - connection holes 34a, and the mounting table 33 is provided with a plurality of through - holes 33a corresponding to the screw - connection holes 34a; the vibrator mounting device 100 further includes a plurality of limiting screw - connectors 5. The limiting screw - connectors 5 are passed through the screw - connection holes 34a and the through - holes 33a, so that the mounting table 33 and the rotating table 34 are detachably connected. That is, this solution realizes the detachable connection between the rotating table 34 and the mounting table 33 through the limiting screw - connectors 5, the screw - connection holes 34a and the through - holes 33a, with a simple and reliable structure.

[0050] Further, there are multiple mounting platforms 33, and the sizes of the multiple mounting platforms 33 are different. Among them, the sizes of the through holes 33a corresponding to each mounting platform 33 are different; there are multiple groups of screw holes 34a corresponding to the through holes 33a, and the sizes of each group of screw holes 34a are different. There are multiple types of limiting screw connectors 5 corresponding to the screw holes 34a. In this embodiment, when exciters 200 of different specifications and sizes are needed, select the mounting platform 33 of the corresponding size. After installing the exciter 200 on the corresponding mounting platform 33, use the limiting screw connector 5 of the corresponding size and the screw hole 34a to fix the mounting platform 33 on the rotating platform 34, further improving the practicability of the device.

[0051] Furthermore, please refer to Figure 4 and Figure 5 , the rotating platform 34 further includes a main body platform 341 provided on the lifting platform 2 and a transition platform 342 provided between the main body platform 341 and the mounting platform 33.

The transition platform 342 is detachably connected to the main body platform 341, and multiple groups of screw holes 34a are provided on the transition platform 342, so that the transition platform 342 is detachably connected to each mounting platform 33; among them, the transition platform 342 is also provided with a connection hole 342a adapted to the adjustment hole 21a. Thus, in this embodiment, when the rotation angle of the exciter 200 does not need to be adjusted, the rotating platform 34 may not be installed on the lifting platform 2. Instead, after the exciter 200 is fixed on the mounting platform 33, the mounting platform 33 is fixed on the transition platform 342, and the transition platform 342 is directly fixed on the lifting platform 2 by means of the mounting screw connector 321 and the transition hole on the transition platform 342 that is adapted to the adjustment hole 21a, further simplifying the installation steps and making the test more convenient. Specifically, the transition platform 342 and the main body platform 341 are detachably connected by screw connectors.

[0052] Further, please refer to Figure 6 , the mounting platform 33 includes a first platform body 331 detachably connected to the rotating platform 34 and a second platform body 332 provided on the side of the first platform body 331 away from the rotating platform 34. The second platform body 332 is provided with a fixing hole 332a penetrating in the horizontal direction; the fixing portion 31 includes a fixing screw connector 311, and the fixing screw connector 311 is used to pass through the fixing hole 332a and be screwed to the exciter 200 so that the fixed angle between the exciter 200 and the first platform body 331 can be adjusted. In this solution, after adjusting the fixed angle between the exciter 200 and the first platform body 331, through the cooperation of the fixing screw connector 311, the fixing hole 332a and the corresponding hole positions provided on the exciter 200, the exciter 200 is fixed on the second platform body 332 at a preset fixed angle, and the operation is simple. It should be understood that the mating portion on the exciter 200 is the corresponding hole position provided corresponding to the fixing hole 332a. Specifically, the through hole 33a is provided on the first platform body 331.

[0053] It should be noted that, in this embodiment, the first body 331 is horizontally arranged, and the second body 332 is vertically arranged with respect to the first body 331. That is, when adjusting the fixed angle between the vibrator 200 and the first body 331, in essence, the fixed angle between the vibrator 200 and the horizontal plane is adjusted. In addition, the first body 331 is provided with an avoidance opening 331a corresponding to the vibrator 200.

[0054] Further, please refer to Figure 7 , the lifting structure 4 includes a first driving arm 41, a second driving arm 42 and a driving part 43; the upper end of the first driving arm 41 is rotatably arranged on the lifting platform 2 around an axis located in the width direction of the lifting platform 2, and the lower end is provided with a first rolling part 411, and the first rolling part 411 rolls and abuts against the base 1 along the length direction of the lifting platform 2; the second driving arm 42 is arranged in a cross shape with the first driving arm 41, and a rotating shaft is arranged between the middle parts of the second driving arm 42 and the first driving arm 41, and the rotating shaft extends along the width direction of the lifting platform 2.

[0055] In this solution, when the driving part 43 drives the first rolling part 411 to move along the length direction of the lifting platform 2, the first driving arm 41 drives the second driving arm 42 to move through the rotating shaft, so that the second rolling part 421 also moves along the length direction of the lifting platform 2, so as to realize the approach and separation of the first rolling part 411 and the second rolling part 421, that is, to realize the lifting of the lifting platform 2. Specifically, the first rolling part 411 and the second rolling part 421 are arranged in the form of rollers.

[0056] Furthermore, two first driving arms 41 are arranged at intervals along the width direction of the lifting platform 2, a first connecting rod 44 is connected between one ends of the two first driving arms 41, and a transmission rod 46 is arranged between the other ends; correspondingly, two second driving arms 42 are provided, a second connecting rod 45 is connected between one ends of the two second driving arms 42, and a mounting rod 47 is arranged corresponding to the transmission rod 46; the driving part 43 is a driving cylinder 431 rotatably arranged on the mounting rod 47 around an axis in the width direction of the lifting platform 2, and the telescopic end of the driving cylinder 431 is rotatably connected to the transmission rod 46 around an axis in the width direction of the lifting platform 2.

By providing the counterweight bin 6 and the counterweight blocks in this solution, the center of gravity of the vibrator mounting device 100 is lowered to ensure stability. Specifically, in this embodiment, the counterweight bin 6 is detachably connected to the base 1 through a screw connector.
