Description

Technical Field

[0001] This invention relates to the field of laser non-destructive testing equipment technology, specifically to a laser non-destructive testing equipment for industrial parts and its usage method. Background Technology

[0002] Laser non-destructive testing (NDT) devices utilize laser scanning technology to perform non-destructive testing on industrial parts. These devices are specifically designed for rapid, non-contact measurement of critical linear dimensions such as length, thickness, height, and flatness. By accurately capturing three-dimensional morphological data, they provide a reliable basis for product quality control and process improvement.

[0003] However, in the existing technology, when laser non-destructive testing devices inspect the same batch of products, the position and angle of the workpiece may vary, which will cause changes in the laser beam irradiation and reflection angle, thus introducing measurement errors in linear dimensions and affecting the consistency and accuracy of the measurement results.

The inner wall of the semi-circular ring 13 is fixedly connected to the surface of the infrared measuring instrument 12, and the inner walls of the several semi-arc support blocks 14 are in contact with the surface of the semi-circular ring 13.

[0039] The positioning component 9 includes a positioning vertical shell rod 901 threadedly connected to the inner wall of the positioning perforated plate 8, and an adjusting threaded vertical rod 902 rotatably installed on the lower side of the inner wall of the positioning vertical shell rod 901.

Three lifting blocks 904 are fixedly installed on the cylinder wall of the movable cylinder 903. A lifting port 905 is opened on one side of the three lifting blocks 904 on the inner wall of the positioning vertical shell rod 901. The upper end of the adjusting threaded vertical rod 902 extends through to the top surface of the positioning vertical shell rod 901. The three lifting blocks 904 are equidistantly distributed on the periphery of the cylinder wall of the movable cylinder 903, and the surface of the lifting blocks 904 extends to the surface of the positioning vertical shell rod 901 through the lifting port 905.

[0040] The inner wall of the lifting cylinder 906 is in contact with the surface of the positioning vertical shell rod 901, and the lifting cylinder 906 is fixedly installed on the outermost side of the three lifting blocks 904.

A central electrode strip 21 is provided at the center of the top surface of the disc 19, and an outer ring electrode strip 22 is provided on the periphery of the central electrode strip 21 on the top surface of the disc 19. A conductive ball 23 is provided at the center of the top surface of the disc 19. After the operator sees the alarm, the angle of the infrared measuring instrument 12 is finely adjusted by adjusting the semi-circular support block 14. The alarm indication is observed until it disappears, and the calibration is completed.

[0044] A method for using a laser non-destructive testing device for industrial parts, comprising the following steps:

[0045] Step 1: Processing preparation. Processing preparation includes the calibration of the infrared measuring instrument 12 and the installation of the positioning vertical shell rod 901. The calibration of the infrared measuring instrument 12 involves installing the infrared measuring instrument 12 inside the storage tank block 5 and placing the conductive ball 23 at the center of the disk 19. The installation of the positioning vertical shell rod 901 is based on the shape of the measured part. The installation requirement of the positioning vertical shell rod 901 is that it is adapted to the surface of the part to be tested, and several positioning vertical shell rods 901 abut against different outer peripheral positions of the part to be tested, so as to limit the installation posture of the part to be tested during the testing process, so that the part to be tested is in the same preset position each time it is tested.

[0046] Step 2: Component processing. Component processing involves inserting the components to be processed into the internal positions of several positioning vertical shell rods 901 through the positioning perforated plate 8. Then, the infrared measuring instrument 12 is used to measure the placed components, thus completing the component measurement process and the use of the device.

[0047] The working principle of the above embodiments is as follows:

[0048] During the use of the device, the infrared measuring instrument 12 needs to be calibrated and the positioning vertical shell rod 901 needs to be installed. The calibration of the infrared measuring instrument 12 involves installing the infrared measuring instrument 12 inside the storage tank block 5 and placing the conductive ball 23 at the center of the disk 19. The criterion for determining whether the infrared measuring instrument 12 is in a vertical position is the centering effect of the conductive ball 23. When the conductive ball 23 is not centered, it will press on the central electrode strip 21 and the outer ring electrode strip 22. In this way, the conductivity of the conductive ball 23 will energize the two electrode strips. When the electrode strips are energized, the alarm will be activated to ensure the verticality of the infrared measuring instrument 12. Both the alarm and the infrared measuring instrument 12 are existing mature technologies. This application emphasizes the innovative structure and does not elaborate on the existing mature technologies.

[0049] After the infrared measuring instrument 12 is calibrated, the positioning vertical shell rod 901 needs to be installed. The installation of the positioning vertical shell rod 901 is determined according to the shape of the measured part. The installation requirement of the positioning vertical shell rod 901 is to adapt to the surface of the part to be tested, so that the contact surface of each positioning vertical shell rod 901 adapts to the surface contour of the part to be tested, and several positioning vertical shell rods 901 abut against different outer peripheral positions of the part to be tested, so as to limit the installation posture of the part to be tested during the testing process, so that the part to be tested is in the same preset position each time it is tested, ensuring that the position of the part is the same every time, thereby avoiding the problem of inaccurate measurement caused by different placement positions of the part;

[0050] After the positioning vertical shell rods 901 are installed, the parts to be processed are inserted into the internal positions of several positioning vertical shell rods 901 through the positioning perforated plate 8. Since the installation position of the positioning vertical shell rods 901 can ensure that the measurement position of the parts is the same, and the rotation effect of the feeding wheel 907 ensures the smooth output of the parts. Before processing, the dust collection device needs to be connected to the conical connecting pipe 7. This ensures that the suction groove 6 generates suction force, which can then perform dust collection on the surface of the positioning perforated plate 8, avoiding dust and impurities from affecting the accuracy of the measurement. Under the suction output of the dust collection device, the fan blades 1507 will rotate. The rotation of the fan blades 1507 can not only stir the fluid in the chamber, thus preventing dust from accumulating in other positions of the suction groove 6, but also ensure that the dust in the suction groove 6 can better enter the dust collection device through the conical connecting pipe 7 through the gas mixing. The dust collection device of this device is also a mature existing technology. After the parts are installed, the infrared measuring instrument 12 is used to measure the placed parts, thus ending the part measurement process.

[0051] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
