Description

Technical Field

[0001] The utility model relates to the technical field of bearing copper sleeve detection, in particular to a flaw detection device for detecting bearing copper sleeves. Background Art

[0002] Copper sleeves are usually made of copper, aluminum and other materials, and have certain wear resistance and heat resistance. They are often used in low-speed, low-load, and low-precision mechanical equipment. They act as bearings and belong to the category of sliding bearings. They are bearings that work at a sliding friction angle and rotate relative to the shaft. They generally need to be assisted by a lubrication system. Therefore, the smoothness of the inner wall of the copper sleeve is also required to be very high. Only by ensuring smoothness can the friction coefficient of the copper sleeve when it rotates be reduced to a minimum. Ultrasonic flaw detectors are portable industrial non-destructive flaw detectors. They use the characteristics of ultrasonic energy penetrating deep into metal materials and reflecting at the edge of the interface when entering another section from one section to another to check part defects. When the ultrasonic beam passes from the surface of the part through the probe to the inside of the metal, reflected waves are generated when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The position and size of the defect are judged based on these pulse waveforms. It can quickly, conveniently, non-destructively, and accurately detect a variety of defects inside the workpiece, so it can quickly detect whether the bearing copper sleeve has defects. The following problems exist in the prior art:

[0003] Because the existing ultrasonic flaw detector requires manual use of the probe to close to the copper sleeve to detect the surface of the copper sleeve, the detection data will be intuitively displayed on the flaw detector, but when the number of copper sleeves produced is large and the volume is large, the number of probes detected and the area required to be detected for a single copper sleeve will increase significantly, which will cause the detection speed to slow down, thereby affecting the detection efficiency of the copper sleeve.

The probe fixing mechanism 41 is fixedly installed on the rear side of the fixed vertical plate 3, and the plurality of positioning mechanisms 22 include a positioning base plate 221, and the plurality of positioning base plates 221 are fixedly installed in a circular array on the side of the rotating disk 21, and the tops of the plurality of positioning base plates 221 are provided with motor slots 222, and the bottoms of the inner walls of the plurality of motor slots 222 are fixedly installed with rotating motors 223, and the output shafts of the plurality of rotating motors 223 are fixedly installed with clamping mechanisms 224, and the tops of the plurality of positioning base plates 221 are provided with forward buttons 225 on one side, and the tops of the plurality of positioning base plates 221 are provided with reverse buttons 226 on the other side;

[0021] By starting the rotating motor 12 in the motor slot 11, the rotating disk 21 is driven to rotate as a whole, so that the multiple positioning mechanisms 22 are rotated one by one to the rear side of the probe fixing mechanism 41 on the rear side of the fixed vertical plate 3, and by starting the rotating motor 223 in the motor slot 222 at the top of the positioning bottom plate 221, the overall clamping mechanism 224 can be driven to rotate, so that the fixed copper sleeve is rotated on the rear side of the flaw detector probe 414 for comprehensive detection.

[0022] like Figure 4 As shown, several clamping mechanisms 224 all include cylindrical boxes 2241, and connecting rods 2242 are fixedly installed on the inner wall sides of several cylindrical boxes 2241, and two-way shaft motors 2243 are fixedly installed on one end of several connecting rods 2242 away from the inner wall side of the cylindrical box 2241, and motor control modules 2244 are fixedly installed on the sides of several two-way shaft motors 2243.

[0026] The following is a detailed description of the working principle of the flaw detection device used to detect bearing copper sleeves.

[0027] like Figure 1-5As shown, during processing, the copper sleeve is evenly placed on the top of the clamping mechanism 224 included in the plurality of positioning mechanisms 22, and then the forward button 225 is pressed to receive the signal using the motor control module 2244, thereby starting the bidirectional shaft motor 2243 in the cylindrical box 2241, driving the two output shafts to rotate in the forward direction, causing the two threaded rods 2245 with opposite threads to rotate at the same time, thereby allowing the two hanging plates 2246 passing through the slide groove 2247 to move in opposite directions, thereby using the arc plate 2248 to clamp the inner ring of the copper sleeve on both sides to fix the copper sleeve, and then the rotating motor 12 in the motor slot 11 is started to drive the rotating disk 21 to rotate as a whole, thereby rotating the plurality of positioning mechanisms 22 one by one to the rear of the probe fixing mechanism 41 on the rear side of the fixed vertical plate 3 By starting the electric telescopic rod 412 on the rear side of the fixed bracket 411, the connecting plate 413 can be used to drive the flaw detector probe 414 to approach the fixed copper sleeve, and finally by starting the rotating motor 223 in the motor slot 222 on the top of the positioning base plate 221, the overall clamping mechanism 224 can be driven to rotate, so that the fixed copper sleeve rotates on the rear side of the flaw detector probe 414 for comprehensive detection.
