Therefore, bolts undergo ultrasonic testing before use. However, dust often adheres to the bolt surface, which can obscure tiny cracks, affecting the accuracy of the testing results and leading to poor coupling between the ultrasonic probe and the bolt surface, further reducing the reliability of the testing. Most existing bolt testing methods do not fully consider the importance of surface cleaning for testing effectiveness, thus affecting the efficiency and accuracy of bolt testing and posing potential risks to equipment maintenance and safe operation. Therefore, an ultrasonic testing device for bolt testing is needed. Utility Model Content

[0003] The purpose of this invention is to address the problem in the existing technology where dust adhering to the surface of bolts affects the accuracy of flaw detection, and to propose an ultrasonic flaw detection device for bolt flaw detection.

The flaw detection assembly includes a flaw detection host, a wire connected to the flaw detection host, and a flaw detection head connected to one end of the wire. A horizontally movable brush is installed on the side of the L-shaped bracket. A stepper motor is fixedly connected to the top of the L-shaped bracket. The piston rod of the stepper motor is fixedly connected to the flaw detection head. A support base is fixedly connected to the base. A funnel is fixedly connected to the support base. A filter screen is detachably installed inside the funnel. A negative pressure fan is connected to the side of the funnel. A turntable is rotatably connected to the funnel.

Detailed Implementation

[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures. They should not be construed as limiting the utility model. To better illustrate the embodiments of this utility model, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the figures for those skilled in the art.

[0020] like Figure 1 As shown, this utility model discloses an ultrasonic flaw detection device for bolt flaw detection, including a base 1 and an L-shaped bracket 2. A flaw detection component is fixedly installed on the L-shaped bracket 2. The flaw detection component includes a flaw detection host 201, a wire connected to the flaw detection host 201, and a flaw detection head 221 connected to one end of the wire. The flaw detection component adopts Zhongke Hanwei H700. The flaw detection host 201 sets the data and uses the flaw detection head 221 to detect flaws in the bolt. A horizontally movable brush 211 is installed on the side of the L-shaped bracket 2. A cylinder 210 is fixedly connected to the side of the L-shaped bracket 2. The piston rod of the cylinder 210 is fixedly connected to the brush 211. The cylinder 210 pushes the brush 211 to clean the surface of the bolt.

[0021] like Figure 2 , Figure 3 As shown, a stepper motor 220 is fixedly connected to the top of the L-shaped bracket 2. The piston rod of the stepper motor 220 is fixedly connected to the flaw detector head 221. The stepper motor 220 pushes the flaw detector head 221 to contact the surface of the bolt for flaw detection. Compared with manual force, the machine applies force more evenly, allowing the flaw detector head 221 to better contact the bolt surface for flaw detection. A support base 3 is fixedly connected to the base 1, and a funnel 4 is fixedly connected to the support base 3 to facilitate dust falling onto the filter screen 401. The filter screen 401 is detachably installed inside the funnel 4. The inner wall of the funnel 4 has a screw groove. The filter screen 401 is removed and installed by bolts and screw grooves. When too much dust accumulates on the filter screen 401, it is replaced to avoid affecting subsequent use. A negative pressure fan 6 is connected to the side of the funnel 4. A hose 601 is fixedly connected between the negative pressure fan 6 and the funnel 4. The rotation of the negative pressure fan 6 adsorbs the cleaned dust onto the filter screen 401, preventing it from affecting equipment performance and causing environmental pollution.

[0022] like Figure 3 , Figure 4As shown, a turntable 5 is rotatably connected to the funnel 4, a servo motor 301 is fixedly connected to the bottom of the support base 3, and a rotating rod 302 is rotatably connected to the support base 3. A rotating opening is opened at the bottom of the funnel 4, and a bearing is installed inside the rotating opening. The rotating rod 302 is fixedly connected to the inner ring of the bearing and rotatably connected to the servo motor 301. A cross support rod 303 is fixedly connected to the rotating rod 302. The rotating rod 302 rotates through the filter screen 401, so that the rotating rod 302 does not affect the dust collection of the filter screen 401. The cross support rod 303 is fixedly connected to the inner wall of the turntable 5. The servo motor 301 drives the turntable 5 to rotate, which is used to rotate the bolts. The rotating cleaning follows the threads to clean them, preventing dead corners from being missed, thus affecting the accuracy of the flaw detection. At the same time, rotating the bolts during flaw detection allows for better flaw detection of the bolts.

[0023] like Figure 1 As shown, the turntable 5 is equipped with a clamp, which includes two cylinders 501 fixedly connected to the outer curved surface of the turntable 5. The turntable 5 is equipped with two clamping plates 502. The piston rod of the cylinder 501 is fixedly connected to the clamping plate 502. The double-sided clamping provides a more secure fixation for the bolt, preventing the bolt from shaking and affecting the flaw detection. The flaw detection head 221 is located above the clamp. The two cylinders 501 push the clamping plate 502 to fix the bolt. The double-sided clamping provides a more secure fixation for the bolt, preventing the bolt from shaking and affecting the flaw detection.

[0024] In this embodiment, the flaw detection host 201 adjusts the data, causing two cylinders 501 to push the clamping plate 502 to clamp the bolt. Double-sided clamping provides a more secure fixation of the bolt, preventing bolt wobbling from affecting the flaw detection. The servo motor 301 starts, driving the turntable 5 to rotate. Cylinder 210 pushes the brush 211 to clean the bolt surface, rotating and cleaning along the threads to prevent blind spots from affecting the accuracy of the flaw detection. The negative pressure fan 6 rotates, generating airflow that adsorbs the cleaned dust onto the filter screen 401, preventing dust from scattering and affecting equipment performance and causing environmental pollution. After cleaning, cylinder 210 pulls the brush 211 away from the turntable 5, and then the stepper motor 220 pushes the flaw detection head 221 to fit against the bolt surface for ultrasonic flaw detection to check for defective products. Treating the bolt surface increases the accuracy of the flaw detection results and enhances the coupling effect between the ultrasonic probe and the bolt surface.

[0025] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
