[0002] Before implementing TOFD detection technology, the welds of steel spherical tanks with painted surfaces must be polished to reveal the original color of the metal. Therefore, it is necessary to study the TOFD detection method for high-strength steel spherical tank butt welds with paint.

[0003] Studying the feasibility of TOFD detection under unpainted conditions to verify the validity of the detection data under painted conditions is a prerequisite for studying the TOFD detection method applied to painted conditions of high-strength steel spherical tank butt welds. Therefore, comparative testing is required, so the outer wall of the steel spherical tank body sample needs to be polished. Since it is local polishing, the polishing method is mostly manual polishing with sandpaper or grinder, but this method is not only labor-intensive, but also easily causes uneven polishing, reducing the quality of polishing.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 The invention discloses a sample processing device for TOFD detection and calibration of welds of steel ball tanks, comprising a guide seat 1, which is arranged in a rectangular body. A guide hole penetrating the left and right outer walls of the guide seat 1 is provided on the guide seat 1, and four guide grooves are provided in an array on the inner wall of the guide hole. The guide grooves all penetrate the left and right outer walls of the guide seat 1, and one of the guide grooves penetrates the upper side wall of the guide seat 1 outwardly. A sleeve 2 is slidably inserted in the guide hole, and an insert plate 3 slidably inserted in the corresponding guide groove is fixedly connected to the outer wall of the sleeve 2. The insert plate 3 limits the sleeve 2 to prevent the sleeve 2 from rotating in the guide hole. A tooth plate 4 is fixedly provided on the insert plate 3 located in the guide groove penetrating the upper wall of the guide seat 1, and the tooth plate 4 is arranged in a strip shape along the outer wall of the insert plate 3. An adjustment mechanism is provided on the upper wall of the guide seat 1.

[0020] The adjusting mechanism comprises two rotating seats 7 symmetrically arranged on the upper side of the guide seat 1, and the two rotating seats 7 are arranged front and back. A slide groove 8 is provided on the upper wall of the guide seat 1 and is located on the lower side of the rotating seat 7. The slide groove 8 is arranged in the left and right directions. Slide blocks are slidably arranged in the slide groove 8, and the slide blocks are respectively fixedly connected with the corresponding rotating seats 7. A rotating shaft 9 is inserted between the two rotating seats 7 for common movement. A gear 10 is fixedly sleeved in the middle of the rotating shaft 9. The gear 10 extends into the guide groove and meshes with the gear plate 4. Threaded holes are provided on the rotating seats 7, and studs are inserted in the threaded holes. The inner ends of the studs are in contact with the outer walls of the rotating shaft 9. The outer ends of the studs are fixedly connected with a rotating handle 11 located on the outer side of the rotating seat 7. After tightening the rotating handle 11, the inner end of the stud will squeeze the rotating shaft 9, so that the rotating shaft 9 is fixed to the rotating seat 7. At the same time, the gear 1 0 is fixed, a fixing rod 12 located on the left side of the rotating seat 7 is fixedly provided on the upper wall of the guide seat 1, and a spring 13 is connected between the rotating seat 7 and the fixing rod 12. The outer wall fixing sleeve of the rotating shaft 9 is provided with two anti-skid sleeves 16, and the two anti-skid sleeves 16 are respectively located on both sides of the gear 10. The anti-skid sleeves 16 are conducive to driving the rotating shaft 9 to rotate, and can also limit the rotating shaft 9 to reduce the sliding of the rotating shaft 9 along the axial direction. The gear 10 is driven to rotate by the rotating shaft 9, and the gear 10 is meshed with the tooth plate 4. The tooth plate 4 will drive the sleeve 2 to move on the guide seat 1 to adjust the position of the sleeve 2. When the gear 10 is fixed, the rotating shaft 9 can push the rotating seat 7 to move downward by a certain distance under the push of external force, that is, the sleeve 2 has a small degree of elasticity in the axial direction, and the spring 13 is compressed at this time.

[0021] The left and right ends of the sleeve 2 are respectively opened and sealed. A motor 5 is fixedly arranged inside the sleeve 2. The driving end of the motor 5 points to the open end of the sleeve 2. The driving end of the motor 5 is fixedly connected to a grinding disc 6 located on the left side of the guide seat 1. The outer wall of the steel ball tank is grinded by the rotation of the grinding disc 6.

[0022] The left side wall of the guide seat 1 is provided with four supporting mechanisms located on the outside of the grinding disc 6. The supporting mechanisms include supporting seats 14 fixed at each corner of the left wall of the guide seat 1. Rollers 15 are provided on the supporting seats 14, and the rollers 15 are rotatably arranged at the left end of the supporting seats 14. The axes of the rollers 15 are arranged parallel to each other. The guide seat 1 is pressed against the outer wall of the steel ball tank through the supporting mechanism, and the rollers 15 are squeezed and contacted with the outer wall at the weld. The position of the sleeve 2 is adjusted to make the grinding disc 6 approach the outer wall of the steel ball tank, the motor 5 is started, and the grinding disc 6 rotates. A gasket 17 is fixedly provided in the middle of the left side wall of the sleeve 2. The sleeve 2 is pressed down to move the sleeve 2 toward the outer wall of the steel ball tank. The grinding disc 6 will contact the outer wall at the weld and grind and remove the paint. The guide seat 1 can be moved by the rollers 15 for mobile grinding, and the grinding is relatively uniform, which improves the quality of grinding and reduces the labor of workers.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
