Description

Technical Field

[0001] The invention relates to the technical field of metal material detection, in particular to a nondestructive detection device for round bar and round tube metal materials. Background Art

[0002] Nondestructive testing refers to a method of inspecting and testing the structure, properties, state and type, nature, quantity, shape, position, size, distribution and changes of defects inside and on the surface of the test piece by using physical or chemical methods, with the help of modern technology and equipment, without damaging or affecting the performance of the tested object or the internal organization of the tested object. In the process of nondestructive testing of round bar and round tube metal materials, the material needs to be clamped to ensure the stability of the material and the accuracy of the test. However, the existing testing equipment cannot clamp the material to adapt to the diameter of the material, and the detection range is small.

[0003] Patent No. CN201711435418.5 discloses a non-destructive testing device for round rods and round tubes of metal materials. The patent is set on the control machine after connecting the power supply. The material is transported and tested by the material conveyor, and the damaged material is clamped and transferred by the transfer mechanism. When the material is transported to the specified position, it is detected whether there is damaged material. If so, the rotation of the lifting and rotating shaft is realized through the induction setting. After the lifting and rotating shaft rotates, it drives the swing of the driving shaft rod to make the driving block slide downward on the slide frame. When the slide frame moves, it drives the rotation of the threaded ring frame. After the threaded ring frame rotates, it drives the threaded push rod body threadedly connected to it to push, and the threaded push rod body pushes After that, the motor switch is triggered to start the motor running; the threaded push rod body pushes the fixed rotating shaft to rotate, which drives the linked rotating frame to rotate the reverse driving wheel, and the rotation of the reverse driving wheel drives the rotation of the I-beam shaft rod. When the I-beam shaft rod rotates, the rotating rod also rotates, driving the clamping robot to rotate; the threaded ring frame rotates and drives the two pullers to pull at the same time, which is used to clamp the damaged material. After the two pullers pull the connecting cover, the connecting cover is buckled at both ends of the slide frame. This patent makes it difficult to detect the inner and outer surfaces of the metal round tube, and it will also affect the detection of the metal round bar. Therefore, a non-destructive testing equipment for round bar and round tube metal materials is proposed to solve the above-mentioned problems. Summary of the invention

The internal detection module detects the inner wall of the metal round tube. When a batch of metal round bars need to be inspected, the transmission sleeve is slid to the side away from the detection box. The arc groove in the transmission sleeve squeezes the block downward through the guiding force of the arc surface, so that the block is retracted into the connecting shaft. At this time, the connecting shaft cannot be connected to the transmission sleeve through the block, nor can it rotate with the transmission shaft, so that the threaded sleeve and the internal detection module cannot move into the detection box. At this time, the metal round bars can be inspected.

The transmission shaft rotates to drive the eccentric wheel to rotate, and the eccentric wheel drives the driving shaft to rotate circumferentially. When the driving shaft rotates circumferentially, the slide groove transmission frame is driven up and down reciprocatingly by the slide groove transmission frame, and the transmission connecting rod and the sliding bar are driven up and down reciprocatingly. When the sliding bar drives the inclined block to move up, the pushing inclined block pushes the bottom end of the clamping jaw to move forward and backward, so that the top ends of the clamping jaws are close to each other, and the rising distance of the pushing inclined block is different, so that the distance between the top ends of the clamping jaws is different.

When the pusher inclined plate moves downward, the tube and round bar materials that fall onto the placement frame through the feed chute are stuck in the placement frame because of their own arc surface. When the transmission rod rises, the lifting rod, lifting shaft and lifting baffle are lifted up, so that the lifting baffle cannot block the tube and round bar materials. When the transmission rod descends, it drives the lifting rod, lifting shaft and lifting baffle to descend, so that the lifting baffle blocks the front side of the tube and round bar materials.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects:

[0009] 1.

[0010] 2. In the non-destructive testing equipment for round bars and round tubes of metal materials, the top ends of the jaws are close to each other and can clamp the material, so that the material remains stable during testing and the detection accuracy is improved.

[0011] 3. For the non-destructive testing equipment for round bars and round tubes, when the pusher inclined plate moves downward, the round tubes and round rods that fall onto the placement frame through the feed chute are stuck in the placement frame due to their own arc surface, and thus cannot be moved to the fixed frame, thereby achieving uniform feeding and facilitating testing. The lifting baffle blocks the front side of the round tubes and round rods, further preventing the materials from falling in advance, improving the use effect of the device, making the testing time uniform and controllable, and improving the testing effect.
