Description

Technical Field

[0001] The invention relates to the technical field of titanium alloy part detection, and in particular to a titanium alloy part surface defect detection device. Background Art

[0002] Aluminum alloy parts are widely used in the fields of automobiles, ships, construction, machinery manufacturing, aviation and aerospace, but there are often various defects on their surfaces, such as scratches, pores, shrinkage holes, depressions, lines and burrs. Therefore, it is often necessary to detect the surface defects of aluminum alloys to ensure the quality of parts. However, defect detection currently often relies on manual work, which is inefficient and may cause missed detections, making it difficult to meet the needs of large-scale automated production.

[0003] The existing Chinese patent application with publication number CN114778564A discloses a surround-type detection device for surface defects of aluminum alloy parts, including a bracket, a clamping and fixing device, a circular track device, an LED strip light source, an industrial camera fixing device, and an industrial camera moving and fixing device; the clamping and fixing device fixes the detection object by contracting the cylinder, the circular track device is powered by a servo motor, the moving paddle drives the track trolley to move and change the angle, and drives the industrial camera to continuously capture images of the curved surface, and the LED strip light source is distributed on the corresponding inner surface and beam of the bracket; the industrial camera satisfies the needs of the manipulator to place and remove the detection object and collect images through the contraction of the cylinder; finally, the full surface detection is completed, and the manipulator classifies and places the detection object according to the system feedback results. This invention solves the problems of low efficiency and low accuracy of traditional manual detection, and greatly improves the detection efficiency.

[0004] The existing Chinese patent application with publication number CN113281136A discloses a method for detecting arc burn defects on the surface of titanium alloy parts, which belongs to the field of arc burn detection technology. First, the induction coil influence area on the surface of the titanium alloy part is degreased. Because the oil on the surface of the part is not cleanly degreased, the solution will not infiltrate the surface of the part, and the surface arc burn inspection cannot be achieved. Degreasing is to prepare for the subsequent arc burn inspection, that is, to provide a clean surface that can react with the burn inspection solution. The use of chemical methods to inspect areas prone to arc burns can effectively identify and exclude any parts with arc burns, thereby ensuring the reliability and safety of the engine. It avoids installing parts with burn defects into aircraft engines, and eliminates part fatigue fracture failures caused by burns.

[0005] However, the processing platform has the following defects when used:

[0006] 1. When the existing surface defect detection device is used to detect aviation titanium alloy parts, although the titanium alloy parts can be well installed and fixed, the outer wall profile of the clamping block is relatively fixed, and the clamping blocks with different outer wall profiles are not convenient to be assembled and disassembled. As a result, when the surface defect detection device is used to detect surface defects of aviation titanium alloy parts of different shapes, the clamping and fixing effect of titanium alloy parts with different profiles is not high, which affects the stability of the placement of the titanium alloy parts during adjustment and detection, and further causes the titanium alloy parts to loosen, fall, and shake, affecting the stability of surface defect detection of aviation titanium alloy parts;

[0007] 2. When the existing surface defect detection device is inspecting aviation titanium alloy parts, although the industrial camera can be adjusted in a circular manner, the detection distance between the industrial camera and the aviation titanium alloy parts is relatively fixed, and the convenience of adjusting the detection distance between the industrial camera and the aviation titanium alloy parts is not high. In addition, the dust-proof effect of the end face of the industrial camera when not in use is not high, which can easily cause dust to be absorbed on the surface of the industrial camera when not in use, resulting in dust interfering with the picture during the subsequent defect detection of titanium alloy parts, affecting the accuracy of the surface defect detection data of the titanium alloy parts.
