Description

Technical Field

[0001] This utility model relates to the field of titanium material processing technology, specifically a titanium material weld grinding device. Background Technology

[0002] Titanium and titanium alloys possess a series of excellent properties, including high strength, low density, good corrosion resistance, high temperature resistance, and biocompatibility, leading to their widespread application in numerous fields such as aerospace, shipbuilding, petrochemicals, and medical devices. In these applications, titanium materials are often joined using welding processes to achieve structural integrity and functionality. However, welding inevitably produces some defects at the weld seam, such as uneven weld surface, spatter, and oxide scale. This necessitates grinding the weld seam to improve its quality and appearance. Titanium weld seam grinding equipment is used to grind the weld seam formed after titanium welding, aiming to make the weld seam surface smooth and flat, meeting relevant quality and process requirements.

[0003] During the grinding process of ring-shaped titanium materials, the grinding head or abrasive belt of the grinding tool should be at a certain angle to the weld surface and moved slowly along the weld direction. The grinding speed should not be too fast to avoid oxidation or deformation of the titanium surface due to overheating. The internal space of the titanium ring is relatively small, and the movement space of the grinding equipment and tools is limited. Especially for large-diameter, thick-walled titanium rings, it is difficult for operators to accurately insert the tools into the inner weld for grinding. In addition, during the grinding process, the tools are prone to collision with other parts of the inner wall of the titanium ring, affecting the grinding effect and operational safety.

[0006] The base has an annular groove inside its top end, and multiple first sliders are provided inside the annular groove. A rotating plate is installed on the top end of each first slider, and multiple connecting brackets are installed on the outer side of the top end of the rotating plate. A placement platform is installed on the top end of each connecting bracket.

A second threaded block is threadedly connected to the outer wall of the one-way threaded rod, and multiple push rods are installed on the outer side of the second threaded block. Transverse sliding grooves are opened inside the sides and front and rear ends of the placement platform, and sliding rods are installed inside the transverse sliding grooves. A second slider is slidably connected to the outer wall of the slider, and a fixed support foot is installed at the top of the second slider. A drive motor is installed at the bottom of the base, and a drive gear is installed at the output end of the drive motor. A driven rotating rod is installed at the bottom center of the rotating plate, and a driven gear is installed at the bottom end of the driven rotating rod.

[0024] The grinding structure includes a lifting box 7, which is installed on the side of the lifting assembly 10 near the rotating plate 2. A first servo motor 6 is installed on one side of the lifting box 7. A bidirectional threaded rod 11 is installed at the output end of the first servo motor 6.

[0025] The fixed structure includes a fixed box 18, which is installed at the bottom middle position of the placement platform 4. A second servo motor 17 is installed at the bottom of the fixed box 18, and a one-way threaded rod 22 is installed at the output end of the second servo motor 17. A second threaded block 21 is connected to the outer wall of the one-way threaded rod 22 by a thread, and multiple push rods 19 are installed on the outer side of the second threaded block 21. Transverse sliding grooves 25 are opened in the interior of both sides and the front and rear ends of the placement platform 4, and a sliding rod 24 is installed inside the transverse sliding groove 25. A second slider 23 is slidably connected to the outer wall of the sliding rod 24, and a fixed support foot 5 is installed at the top of the second slider 23.

[0026] A drive motor 12 is installed at the bottom of the base 1, and a drive gear 13 is installed at the output end of the drive motor 12. A driven rotating rod 15 is installed at the middle position of the bottom of the rotating plate 2, and a driven gear 14 is installed at the bottom of the driven rotating rod 15.

[0027] The top end of the one-way threaded rod 22 extends through the fixed box 18 to the top end inside the fixed box 18, and the one-way threaded rod 22 is rotatably mounted on the top end inside the fixed box 18.

[0028] The top of each push rod 19 extends to the bottom of the second slider 23, and each push rod 19 is hinged to the bottom of the second slider 23.

[0029] One end of the bidirectional threaded rod 11 passes through the lifting box 7 and extends to one side inside the lifting box 7, and the bidirectional threaded rod 11 is rotatably installed on one side inside the lifting box 7.

[0030] The bottom end of the driven rotating rod 15 passes through the base 1, and the bottom end of the driven rotating rod 15 extends to the bottom of the base 1;

[0031] Driven gear 14 is located above drive gear 13, and driven gear 14 meshes with drive gear 13;

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when using this mechanism, the second servo motor 17 drives the one-way threaded rod 22 to rotate, causing the second threaded block 21 to move upward on the outer wall of the one-way threaded rod 22. The second threaded block 21 pushes the push rod 19, which in turn pushes the second slider 23, causing the second slider 23 to slide outward on the outer wall of the slide rod 24. The second slider 23 drives the fixed support leg 5, causing the fixed support leg 5 to abut against the inner wall of the annular steel strip. The annular steel strip can then be fixed by the fixed support leg 5.

[0033] Working principle: The operator places the annular titanium material to be leveled on the top of the placement platform 4, then starts the second servo motor 17, which drives the one-way threaded rod 22 to rotate, causing the second threaded block 21 to move upward on the outer wall of the one-way threaded rod 22. The second threaded block 21 pushes the push rod 19, which in turn pushes the second slider 23, causing the second slider 23 to slide outward on the outer wall of the slide rod 24. The second slider 23 drives the fixed support 5, causing the fixed support 5 to abut against the inner wall of the annular titanium material, thus fixing the annular titanium material. Then, the operator starts the lifting assembly 10, causing the lifting box 7 to move downward. Then, the first servo motor 6 is started, which drives the bidirectional threaded rod 11 to rotate. Since the first threaded block 8 is located on the outer wall of the bidirectional threaded rod 11... The two parts of the thread are reversed, so during the rotation of the bidirectional threaded rod 11, the first threaded block 8 can move towards each other on the outer wall of the bidirectional threaded rod 11. The first threaded block 8 drives the grinding column 9 to move closer to each other and fit tightly against the annular titanium material. Then the operator starts the drive motor 12, which drives the drive gear 13 to rotate. Since the drive gear 13 and the driven gear 14 mesh with each other, the drive gear 13 drives the driven gear 14 to rotate. The driven gear 14 drives the driven rotating rod 15 to rotate. The driven rotating rod 15 drives the rotating plate 2 to rotate. The rotating plate 2 drives the first slider 16 to slide inside the annular groove 20, thereby driving the placement platform 4 and the annular titanium material to rotate. Through the rotation of the annular titanium material, the grinding column 9 grinds the weld seams inside and outside the annular titanium material at the same time.
