[0024] This device includes:

[0025] A workbench 10;

[0026] A pair of clamping seats 21 movably arranged on the top of the workbench 10;

[0027] A cleaning structure, which is arranged on one of the clamping seats 21. The cleaning structure includes a rotating rod 31, the rotating rod 31 is rotatably arranged on the top of the clamping seat 21, a second driving member 32 is arranged on the rotating rod 31, the output end of the second driving member 32 is horizontally arranged and connected with a brush holder 33, and a rotatable brush roller 34 is arranged on the brush holder 33;

[0028] Rotate the rotating rod 31 to rotate the brush roller 34 to the position where the workpiece is located. The rotating brush roller 34 sweeps the dust attached to the workpiece, and the second driving member 32 drives the brush roller 34 to move horizontally to change the cleaning position.

[0029] Through a pair of movably arranged clamping seats 21, the clamping and fixing of the pump casting to be tested can be realized. Through the arranged cleaning structure, the dust on the detection surface of the pump casting can be cleaned, so as to avoid the influence of dust attached to the detection surface on the flaw detection process and results, and ensure the sensitivity of flaw detection and the accuracy of detection results.

[0030] Specifically, the cleaning method of the arranged brush roller 34 is relatively gentle, avoiding possible damage to the pump casting during the cleaning process; on the other hand, the bristles of the brush roller 34 can also extend into the gaps for cleaning, and the cleaning effect is good.

[0031] The second driving member 32 is an electric telescopic rod. The telescopic movement of the output end of the second driving member 32 can drive the brush roller 34 to reciprocate horizontally, which can change the cleaning position of the brush roller 34 and make the device more flexible.

[0032] The rotating rod 31 is rotatably arranged on the clamping seat 21 through a turntable on the top of the clamping seat 21, and can be rotated by an external force. Thus, after the pump casting is cleaned by the brush roller 34, the brush roller 34 can be rotated to the other side to ensure the normal progress of the flaw detection work; and when the cleaning work is carried out under normal conditions, the brush roller 34 is in a stable state, that is, the rotating rod 31 and the turntable can be driven to rotate only under a certain external force.

[0033] A third driving member 35 is further provided on the brush holder 33. The output end of the third driving member 35 is connected to the brush roller 34, and the third driving member 35 drives the brush roller 34 to rotate. The third driving member 35 is a motor, which functions to drive the brush roller 34 to rotate.

[0034] As Figure 1 , Figure 2 , Figure 3 shown, Figure 1 The figure shows a schematic diagram of the structure of the flaw detection device in the embodiment Figure One ; Figure 2 The figure shows a schematic diagram of the structure of the flaw detection device in the embodiment Figure Two ;

[0035] An installation frame is provided at the top end of the workbench 10. The installation frame includes vertical frames 11 arranged oppositely and a horizontal frame 12 located between the two vertical frames 11. A first driving member 22 is provided at one end of the two vertical frames 11 close to each other. The output ends of the first driving member 22 are respectively connected to the L-shaped clamping seats 21 on the corresponding sides. After the workpiece to be tested is placed on the two clamping seats 21, they move closer to each other to clamp the workpiece.

[0036] A guide rod 23 is horizontally arranged between the two vertical frames 11 and below the clamping seats 21. Sliders 24 are provided at the bottom ends of the clamping seats 21, and the sliders 24 are slidably sleeved on the guide rod 23.

[0037] The guide rod 23 and the slider 24 slidably engaged therewith are provided to guide the clamping seat 21, so that the clamping seat 21 remains stable during the moving process. Specifically, the guide rod 23 is rectangular, and the first driving member 22 is an electric telescopic rod.

[0038] A flaw detector 40 is movably provided at the bottom end of the horizontal frame 12 and corresponding to the workpiece to be tested.

[0039] The flaw detector 40 is a prior art and will not be elaborated here. It is installed through a moving module provided on the horizontal frame 12. The moving module can drive the flaw detector 40 to move in the horizontal and vertical directions, so as to adjust the detection position according to actual needs.

[0040] Working principle: When the device is in use, first place the pump casting to be tested on the two clamping seats 21, then turn on the first driving member 22 to make the two clamping seats 21 move closer to each other, so as to clamp and fix the pump casting. Then, rotate the rotating rod 31 by an external force to rotate the brush roller 34 to the position of the workpiece, and start the second driving member 32 to adjust the brush roller 34 to the specific cleaning position. Finally, turn on the third driving member 35 to make the brush roller 34 rotate to achieve cleaning.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
