Support feet are installed at the four corners of the bottom of the base. One end of the outer side of the base is embedded with a control panel. A groove is opened at the center of the top of the base. An electric telescopic column is installed inside the groove on the top of the base. Support plates are symmetrically installed at both ends of the top of the base. First electric telescopic rods are installed at the inner tops of the support plates. A detection joint is installed at one end of the first electric telescopic rod. In this utility model, the detection process of the attenuator is completed automatically, with high efficiency and accurate detection and positioning. There is no need for too much operation by the detection personnel, thus greatly improving the detection efficiency of the attenuator.

[0004] Although the above device has an adjustment structure to assist docking, it does not have a compensation structure. Therefore, if there is a position deviation during the operation of the device, it will directly lead to docking errors, and the two interfaces will be directly squeezed and damaged without a compensation effect, resulting in a low fault tolerance rate of the device and easy damage to the device. For this reason, in view of the above defects, this application proposes an attenuator testing device. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 and Figure 2 The present utility model provides a technical solution: including a base 1, a pushing component 2 is arranged at the rear side of the upper end of the base 1, and a first compensation component 3 is arranged on the side of the pushing component 2 close to the central axis of the base 1. The first compensation component 3 includes a connecting frame 301, a connecting block 302, a first spring 303 and a guide rod 304. A connecting block 302 is arranged in the middle of the side of the connecting frame 301 away from the pushing component 2. The front and rear sides of the connecting block 302 are connected with a first spring 303, and a guide rod 304 is arranged inside the first spring 303;

[0021] The connecting block 302 and the connecting frame 301 form an elastic sliding structure through the first spring 303 and the guide rod 304. Through the elastic sliding structure, the first detection joint 4 can move forward and backward, so that when the first detection joint 4 is misaligned, the position of the first detection joint 4 can be compensated by the forward and backward movement effect, making the docking of the device have a certain error tolerance, so that position compensation can also be carried out for alignment work when misaligned, ensuring the normal operation of the device.

[0022] As Figure 1As shown, the pushing component 2 includes a first support frame 201 and a first cylinder 202, and the first cylinder 202 is installed through the upper end of the first support frame 201;

[0023] The first cylinder 202 installed on the first support frame 201 is used to push the first detection joint 4.

[0024] As Figure 1 , Figure 2 and Figure 3 shown, a first detection joint 4 is connected to one side of the first compensation component 3 away from the pushing component 2, and a first auxiliary docking component 5 is arranged around the first detection joint 4. An attenuator body 6 is arranged on the side of the first detection joint 4 away from the first compensation component 3, and a positioning component 7 is arranged below the attenuator body 6. An operation display platform 12 is arranged at the front end above the base 1. A second detection joint 8 is arranged on the side of the attenuator body 6 away from the first detection joint 4, and a second auxiliary docking component 9 is arranged around the second detection joint 8. A second compensation component 10 is connected to the side of the second detection joint 8 away from the attenuator body 6, and a second support frame 11 is connected to the side of the second compensation component 10 away from the second detection joint 8.

[0025] As Figure 2 shown, the first auxiliary docking component 5 includes a mounting block 501, a rotating plate 502, a second spring 503, a mounting frame 504 and a rolling wheel 505. A rotating plate 502 is connected to one side of the mounting block 501 away from the first detection joint 4. A second spring 503 is connected to the middle of the rotating plate 502. A mounting frame 504 is connected to the end of the rotating plate 502 away from the mounting block 501. A rolling wheel 505 is installed at the end of the mounting frame 504 away from the rotating plate 502;

[0026] Relying on the elastic rotating structure formed between the rotating plate 502 and the first detection joint 4 through the mounting block 501 and the second spring 503, the rolling wheel 505 can position the detection head on the attenuator body 6, making it more convenient for the detection head on the attenuator body 6 to be docked with the first detection joint 4, thus facilitating the detection work of the equipment.

[0027] As Figure 3 shown, the positioning component 7 includes a second cylinder 701, a base frame 702, an inlaid positioning block 703, a fixed clamping plate 704, a movable clamping plate 705 and a third cylinder 706. The upper end of the second cylinder 701 is connected to the base frame 702. The inlaid positioning block 703 is installed at the upper end of the base frame 702. A fixed clamping plate 704 is arranged behind the inlaid positioning block 703. A movable clamping plate 705 is arranged in front of the inlaid positioning block 703. A third cylinder 706 is installed at the front end of the movable clamping plate 705;

[0028] The inlaid positioning block 703 is inlaid in the slot below the attenuator body 6 to limit the attenuator body 6. The third cylinder 706 drives the movable clamping plate 705 to move, and the attenuator body 6 is clamped and positioned by the movable clamping plate 705 and the fixed clamping plate 704. The height of the attenuator body 6 can be adjusted by the second cylinder 701.

[0029] Working principle: First, place the attenuator body 6 on the chassis 702, so that the inlaid positioning block 703 is inlaid in the slot below the attenuator body 6, thereby limiting the attenuator body 6. Then, turn on the third cylinder 706 to drive the movable clamping plate 705 to move, so that the attenuator body 6 is clamped and positioned by the movable clamping plate 705 and the fixed clamping plate 704. Then, adjust the height of the attenuator body 6 by the second cylinder 701, so that the detection head on the attenuator body 6 is in line with the first detection joint 4 and the second detection joint 8. Then, turn on the first cylinder 202 installed on the first support frame 201 to push the first detection joint 4, so that the first detection joint 4 is docked with the attenuator body 6. During the docking process, relying on the elastic rotation structure formed by the rotating plate 502, the mounting block 501 and the second spring 503 with the first detection joint 4, the rolling wheel 505 can capture and position the detection head on the attenuator body 6. If there is a position deviation between the detection head on the attenuator body 6 and the first detection joint 4, at this time, the height compensation can be carried out by relying on the lifting of the second cylinder 701. Relying on the elastic sliding structure formed by the connecting block 302, the first spring 303 and the guide rod 304 with the connecting frame 301, the first detection joint 4 can move back and forth to compensate for the front and back positions, so that the first detection joint 4 is aligned with the detection head on the attenuator body 6, and the equipment is docked. When the docking of the first detection joint 4 and the attenuator body 6 is completed, the first cylinder 202 continues to push, and through the slide rail below the positioning assembly 7, the positioning assembly 7 can move, so that the second detection joint 8 is docked with the attenuator body 6 by relying on the second auxiliary docking assembly 9 and the second compensation assembly 10. The first auxiliary docking assembly 5 and the second auxiliary docking assembly 9 have the same structure, and the second compensation assembly 10 and the first compensation assembly 3 have the same structure. When the equipment is detected, the detection results will be displayed on the operation display console 12.
