Description

Technical Field

[0001] This utility model belongs to the field of phased array ultrasonic non-destructive testing technology, and in particular relates to a scraping device for plate phased array flaw detectors. Background Technology

[0002] Currently, in actual production processes, the phased array flaw detection method for sheet metal is the water immersion method. The water layer acts as a coupling medium, allowing ultrasonic waves to smoothly travel from the probe to the workpiece, reducing wear between the probe and the workpiece, and minimizing requirements on the surface finish of the workpiece. Furthermore, the thickness of the water layer can be adjusted to control the propagation path and reflection of the sound waves, thereby optimizing the detection results.

[0003] However, the problem with the water immersion method is that after the test is completed, moisture will remain on the surface of the board as a coupling agent. If the moisture is not removed in time, it will cause the board to rust and be damaged. Utility Model Content

[0004] The purpose of this invention is to solve the problem of corrosion damage caused by coupling agent residue on the surface of the plate after existing flaw detection. It provides a plate scraping device for a phased array flaw detector, which can remove moisture from the surface of the plate in a timely manner, improve the water removal effect without damaging the surface of the plate, ensure the normal use of the plate in the future, and avoid corrosion damage to the plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plate scraping device for a plate phased array flaw detector includes an upper mounting beam and a lower mounting beam that span the plate conveying line. The two beams are parallel to each other, and both ends of the upper and lower mounting beams are fixed to columns on both sides.

[0007] The upper mounting beam is connected to a lifting assembly, a linkage mechanism, an upper wiper pressure plate, and an upper wiper blade that cooperate with each other. The lifting assembly is connected to the upper wiper pressure plate through the linkage mechanism, and the upper wiper blade is fixed to the front end of the upper wiper pressure plate to realize the lifting and lowering of the upper wiper blade.

[0008] A row of scraper hinge seats is connected to the lower mounting beam. The scraper hinge seats are connected to the matching lower wiper pressure plate and lower wiper blade. The lower wiper pressure plate is connected to the wiper shaft. The shaft end of the wiper shaft is connected to the cylinder swing assembly. The cylinder swing assembly is connected to the drive cylinder. Both the cylinder swing assembly and the drive cylinder are located on the outside of the column to realize the rotation and lifting of the lower wiper blade.

[0009] The upper squeegee, upper squeegee, lower squeegee, and lower squeegee are all parallel to each other and the squeegee shaft.

[0010] Furthermore, the lifting assembly includes an L-shaped bracket and a lifting cylinder. The vertical end of the L-shaped bracket is fixed to the upper mounting beam, and the horizontal section extends out and is connected to the lifting cylinder. The telescopic rod at the lower end of the lifting cylinder is vertically downward and connected to the linkage mechanism. A hanging pin is also provided on each side of the horizontal section of the L-shaped bracket.

[0011] Furthermore, the linkage mechanism is a parallelogram structure, comprising a fixed rod, a pair of upper connecting rods, a pair of lower connecting rods, and a mounting rod. The fixed rod and the mounting rod are parallel to each other, and the upper connecting rods and the lower connecting rods are parallel to each other. The fixed rod is connected to the front side of the upper mounting beam. The two upper connecting rods are respectively hinged to the two sides of the upper end of the fixed rod, and the outer side of the upper connecting rod is provided with a fixing pin one and a hanging pin two. The two lower connecting rods are respectively hinged to the two sides of the lower end of the fixed rod, and a horizontal synchronization plate is fixed on the lower connecting rod of each linkage mechanism. The front side of the mounting rod is connected to the upper scraper pressure plate.

[0012] Furthermore, a vertical tension spring connects the first hanging pin on the corresponding side to the first fixing pin, and an oblique tension spring connects the second hanging pin to the back of the upper wiper plate.

[0013] Furthermore, the cylinder swing assembly includes a swing block, a limiting shaft, and an arc-shaped groove. The central axis of the swing block passes through the column and is connected to the wiper shaft. The swing block is provided with a protruding U-shaped seat. The telescopic rod of the drive cylinder is vertically inserted into the U-shaped opening of the U-shaped seat. The U-shaped seat and the telescopic rod end of the drive cylinder are hinged together by the limiting shaft. The shaft end of the limiting shaft passes through the U-shaped opening and is embedded in the arc-shaped groove. The two form a sliding guide fit. The arc-shaped groove is opened on the outside of the column to convert the lifting and lowering movement of the cylinder into the rotational movement of the wiper shaft through the cylinder swing assembly.

[0014] Furthermore, the length of the upper squeegee pressure plate is not less than the length of the upper squeegee, and the hardness of the upper squeegee pressure plate is higher than that of the upper squeegee, so as to press the upper squeegee down through the upper pressure plate to ensure uniform force distribution.

[0015] Furthermore, the length of the lower wiper pressure plate is not less than the length of the lower wiper blade, and the hardness of the lower wiper pressure plate is higher than that of the lower wiper blade, so as to press the lower wiper blade down through the lower pressure plate and ensure uniform force distribution.

[0016] Compared with the prior art, the advantages of the technical solution of this utility model are as follows:

[0017] (1) This utility model can effectively remove the coupling water on the plate after the plate phased array flaw detector is completed, thus improving the water removal effect;

[0018] (2) The present invention provides a fixed squeegee pressure plate on the squeegee so that the materials of different widths can maintain uniform stress when squeegeeing, avoid the squeegee from being excessively worn in some areas, and the force is uniform, which alleviates the phenomenon that the squeegee is not tightly attached to the material due to excessive damage in some areas.

The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0024] See Figure 1 A plate scraping device for a plate phased array flaw detector includes an upper mounting beam 1 and a lower mounting beam 2 spanning the plate conveying line. The two beams are parallel to each other, and both ends of the upper and lower mounting beams are fixed to columns 3 on both sides. Its characteristic is that:

[0025] See Figure 1 and Figure 2 The upper mounting beam 1 is connected to a lifting assembly 4, a linkage mechanism 5, an upper wiper plate 6, and an upper wiper blade 7 that cooperate with each other. The lifting assembly 4 is connected to the upper wiper plate 6 through the linkage mechanism 5. The upper wiper blade 7 is fixed to the front end of the upper wiper plate 6 to realize the lifting and lowering of the upper wiper blade.

[0026] There are two lifting components 4. Each lifting component 4 includes an L-shaped bracket 41 and a lifting cylinder 42. The vertical end of the L-shaped bracket 41 is fixed to the upper mounting beam 1, and the horizontal end extends out and is connected to the lifting cylinder 42. The telescopic rod at the lower end of the lifting cylinder 42 is vertically downward and connected to the linkage mechanism 5. The horizontal section of the L-shaped bracket 41 is also provided with a hanging pin 43 on both sides.

[0027] The linkage mechanism 5 has five components, which are parallelogram structures, including a fixed rod 51, a pair of upper connecting rods 52, a pair of lower connecting rods 53, and a mounting rod 54. The fixed rod 51 and the mounting rod 54 are parallel to each other, and the upper connecting rods 52 and the lower connecting rods 53 are parallel to each other. The fixed rod 51 is connected to the front side of the upper mounting beam 1. The two upper connecting rods 52 are respectively hinged to the two sides of the upper end of the fixed rod 51, and the outer side of the upper connecting rod 52 is provided with a fixing pin 1 55 and a hanging pin 2 56. The two lower connecting rods 53 are respectively hinged to the two sides of the lower end of the fixed rod 51, and a horizontal synchronous plate 57 is fixed on the lower connecting rod 53 of each linkage mechanism 5. The front side of the mounting rod 54 is connected to the upper scraper pressure plate 6.

[0028] A vertical tension spring 14 connects the corresponding hanging pin 43 and the fixing pin 55, and an oblique tension spring 15 connects the second hanging pin 56 and the back of the upper wiper plate 6.

[0029] See Figure 1 and Figure 3 Five scraper hinge seats 8 are connected to the lower mounting beam 2. The scraper hinge seats 8 are connected to the matching lower scraper pressure plate 9 and lower scraper 10. The lower scraper pressure plate 9 is connected to the scraper shaft 11. The shaft end of the scraper shaft 11 is connected to the cylinder swing assembly 12. The cylinder swing assembly 12 is connected to the drive cylinder 13. The cylinder swing assembly 12 and the drive cylinder 13 are both located on the outside of the column 3.

[0030] The cylinder swing assembly 12 includes a swing block 121, a limiting shaft 122, and an arc groove 123. The central axis of the swing block 121 passes through the column 3 and is connected to the wiper shaft 11. The swing block 121 is provided with a protruding U-shaped seat 121a. The telescopic rod of the drive cylinder 13 is vertically inserted into the U-shaped opening of the U-shaped seat 121a. The U-shaped seat 121a and the telescopic rod end of the drive cylinder 13 are hinged together through the limiting shaft 122. The shaft end of the limiting shaft 122 passes through the U-shaped opening and is embedded in the arc groove 123. The arc groove 123 is opened on the outside of the column 3 to convert the lifting and lowering movement of the cylinder into the rotational movement of the wiper shaft through the cylinder swing assembly.

[0033] This invention can effectively remove coupled water from sheet metal after phased array flaw detector testing. Furthermore, because the scraper has a fixed pressure plate, it maintains uniform force on sheet metal of different widths during scraping, mitigating the problem of excessive damage to the scraper causing poor adhesion to the sheet metal. The scraper can also be used in conjunction with a drying device, resulting in faster and more effective water removal compared to existing dewatering devices on the market.

[0034] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
