Abstract
Description
Technical Field
[0001] The utility model relates to the field of non-destructive detection of aluminum products, and more specifically, to a novel support structure of a phased array probe and a wedge block. Background Art
[0002] The general non-destructive inspection method for aluminum products is that the robot's sixth axis drives the phased array probe and wedge to perform water immersion inspection, and the existence and location of defects are determined by calculating the ultrasonic beam echo. The existing connection bracket between the robot's sixth axis and the phased array probe and wedge is composed of a connecting rod plus a linear bearing structure. In order to avoid collision between the probe and the object being inspected, a buffer spring is added in the middle.
[0003] However, due to the gap between the connecting rod and the linear bearing of the existing connecting bracket, the probe as a whole shakes after being used for a period of time. In addition, although the spring can be used to absorb impact during the detection process, the existence of the gap makes it inevitable that the probe shakes left and right, resulting in reduced detection accuracy, increased misjudgment rate, and greatly reduced credibility of the detection results.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0021] See also Figures 1 to 4In the utility model, the support structure of the novel phased array probe and wedge block includes a six-axis robot body 1, a connecting flange 2 is fixedly installed at the end of the sixth axis of the six-axis robot body 1, a linear guide connecting mechanism 3 is installed on the connecting flange 2, a probe connecting rod 4 is installed on the linear guide connecting mechanism 3, a mounting groove 5 is opened on the probe connecting rod 4, a wedge block 6 is installed inside the mounting groove 5, and a phased array probe body 7 is installed on the wedge block 6.
[0022] In the utility model, the six-axis robot body 1 is used as the main body of the device, and the linear guide connection mechanism 3 is connected and fixed to the sixth axis of the six-axis robot body 1 through the connection flange 2, so that the probe connecting rod 4 and the six-axis robot body 1 are rigidly connected, and the linear guide connection mechanism 3 makes the phased array probe body 7 and the wedge block 6 slightly touch the outside, resulting in linear displacement, and reset by the self-gravity on the probe connecting rod 4 after separation. When in use, the six-axis robot body 1 is started to drive the phased array probe body 7 to immerse in water, and the moving guide is 1 to 2 mm away from the object to be detected, and then moves along the track to be detected at a set angle, while detecting and outputting data. When the detection is completed, The arm of the six-axis robot body 1 is raised, and the phased array probe body 7 and the wedge block 6 are moved away from the object to be detected and returned to the initial position to complete a detection process, thereby realizing the advantage of the device having a rigid connection support, so that the bracket is linearly connected along the connecting axis, without relying on springs to absorb energy, avoiding shaking, and improving detection accuracy. It solves the problem that the connection bracket in the prior art has a gap between the connecting rod and the linear bearing, which causes the probe to shake as a whole after a period of use. In addition, although the spring can be used to absorb impact during the detection process, due to the existence of the gap, the left and right shaking of the probe is inevitable, resulting in reduced detection accuracy, increased misjudgment rate, and greatly reduced credibility of the detection results.
[0023] See also Figure 2 and Figure 3 , wherein: the linear guide connection mechanism 3 includes a linear guide rail 31, a guide rail mounting seat 32 and a sliding connecting plate 33, one end of the guide rail mounting seat 32 is fixedly connected to the connecting flange 2 by bolts, the linear guide rail 31 is fixedly mounted to one side of the guide rail mounting seat 32, one end of the sliding connecting plate 33 is movably mounted on the linear guide rail 31, and the other end of the sliding connecting plate 33 is fixedly connected to the probe connecting rod 4.
[0024] In the utility model, the linear guide rail 31 is supported and installed by the guide rail mounting seat 32, and the sliding connecting plate 33 slides linearly on the linear guide rail 31, so that when the probe connecting rod 4 is subjected to force, the sliding connecting plate 33 is pushed to move linearly along the linear guide rail 31, and when the probe connecting rod 4 is not subjected to force, it can be reset by its own gravity, avoiding repeated vibration caused by the use of a spring.
[0025] See also Figure 2 and Figure 4 , wherein: a guide rod 321 is fixedly connected to one side of the guide rail mounting seat 32, a strip groove 331 is opened on the sliding connecting plate 33, and the end of the guide rod 321 away from the guide rail mounting seat 32 extends to the inside of the strip groove 331, and the outer side of the guide rod 321 slides with the inside of the strip groove 331.
[0026] In the utility model, the guide rod 321 cooperates with the strip groove 331 to limit and auxiliary support the sliding connection plate 33, so that the movement stability is better.
[0027] See also Figure 2 and Figure 3 , wherein: a roller 41 is installed on one side of the probe connecting rod 4 , and the roller 41 and the phased array probe body 7 are located on the same side of the wedge block 6 .
[0028] In the utility model, the phased array probe body 7 can be brought close to the object to be detected by the roller 41 and moved along the detection line. The roller 41 contacts and rolls with the object to be detected, thereby maintaining the distance between the phased array probe body 7 and the object to be detected and maintaining a stable distance during detection, thereby preventing the phased array probe body 7 from directly contacting the object to be detected.
[0029] See also Figure 2 , wherein: the side view section of the sliding connecting plate 33 is C-shaped.
[0030] In the present invention, the structure of the C-shaped sliding connecting plate 33 reduces the weight of the structure and facilitates the assembly and disassembly operations at the connection points at both ends.
[0031] See also Figure 2 , wherein: the linear guide 31 is a low-friction linear guide.
[0032] In the utility model, the linear guide rail 31 is a low-friction linear guide rail, which reduces friction and ensures sliding linearity and stability.
[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
