Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, specifically an online small-diameter welded pipe internal burr cutting tool set. Background Technology

[0002] During the welding process, burrs are generated that affect the smoothness of the joint. The presence of burrs directly affects the quality of the welded pipe. The relevant product standard (GB / T33156—2016) specifies detailed clauses for burrs. At present, the removal of burrs in the welded pipe production line is mainly done by cutting, using carbide tools to scrape off the internal burrs. Especially for welded pipes with small diameter (less than 30mm), the removal of burrs is more difficult due to the small working space and the inability to see the inside. Such difficulties are a high-difficulty technology affecting small-scale welded pipe production lines, so the selection of appropriate cutting tools is crucial.

[0003] However, most traditional online small-diameter welded pipe internal burr cutting tool sets are not convenient for flexible adjustment of tool set size. If the tool set size adjustment depends on manual disassembly or tool replacement, the machine must be stopped every time the type is changed or fine adjustment is made, resulting in frequent production line interruptions. When the size adjustment is not accurate, repeated trial cutting verification is required, which further prolongs the downtime. Moreover, tool sets with inconvenient size adjustment are difficult to integrate with robots or CNC systems and cannot achieve adaptive adjustment. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most traditional online deburring tool sets for small-diameter welded pipes are not convenient for flexible adjustment of tool set size. If the tool set size adjustment depends on manual disassembly or tool replacement, the machine must be stopped every time the type is changed or fine adjustment is made, resulting in frequent production line interruptions. When the size adjustment is not accurate, repeated trial cuts are required for verification, which further prolongs the downtime. This utility model proposes an online deburring tool set for small-diameter welded pipes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an online small-diameter welded pipe internal burr cutting tool set, including a tool holder, a sliding groove is provided on one side of the tool holder, the number of the sliding grooves is four, a cutting tool body is provided at the position of each of the four sliding grooves, and an adjustment structure is provided between the tool holder and the cutting tool body.

[0006] The adjustment structure includes a connecting end, one end of which is fixedly connected to one side of the tool holder. A transmission sleeve is slidably fitted onto the surface of the connecting end. A first connecting block is fixedly connected to the surface of the transmission sleeve. There are four first connecting blocks. A connecting rod is rotatably connected to the inner cavity of each of the four first connecting blocks. A transmission plate is rotatably connected to the other end of each connecting rod. A second connecting block is fixedly connected to one side of each transmission plate. The second connecting blocks are slidably connected to the inner wall of a corresponding slide groove. An installation groove is provided on one side of each transmission plate.

[0007] Preferably, a rake face is provided on one side of the cutting tool body, and a flank face is provided on the other side of the cutting tool body.

[0008] Preferably, an extension rod is fixedly connected to one side of the cutting tool body, and a mounting block is fixedly connected to one side of the extension rod. The surface of the mounting block is slidably inserted into the inner wall of the mounting groove.

[0009] Preferably, a pressure plate is provided on one side of the transmission plate, and one side of the pressure plate abuts against one side of the mounting block. A fixing bolt is inserted into the inner cavity of the pressure plate and the inner cavity of the transmission plate.

[0010] Preferably, a push rod is fixedly connected to the inner wall of the transmission sleeve, and the surface of the push rod is slidably connected to the inner wall of the connecting end and the tool holder.

[0025] The adjusting structure 4 includes a connecting end 401, one end of which is fixedly connected to one side of the tool holder 1. A transmission sleeve 402 is slidably fitted onto the surface of the connecting end 401. A first connecting block 403 is fixedly connected to the surface of the transmission sleeve 402. There are four first connecting blocks 403. A connecting rod 404 is rotatably connected to the inner cavity of each of the four first connecting blocks 403. A transmission plate 405 is rotatably connected to the other end of each connecting rod 404. A second connecting block 406 is fixedly connected to one side of each transmission plate 405. The second connecting blocks 406 are slidably connected to the inner wall of the corresponding slide groove 2. An installation groove 407 is opened on one side of each transmission plate 405. A rake face 301 is provided on one side of the cutting tool body 3, and a flank face 302 is provided on the other side of the cutting tool body 3. An extension rod 303 is fixedly connected to one side of the cutting tool body 3. A mounting block 304 is fixedly connected to one side of the tool. The surface of the mounting block 304 is slidably inserted into the inner wall of the mounting groove 407. In this online small-diameter welded pipe internal burr cutting tool set, the tool holder 1 plays the main connecting role. The cutting tool body 3 is connected to the tool holder 1 through the adjustment structure 4. The connecting end 401 plays the main connecting role. The transmission sleeve 402 can slide up and down along the surface of the connecting end 401. When the transmission sleeve 402 rises and falls, it can drive the first connecting block 403 to move together. When the first connecting block 403 rises and falls, it can pull down or push the connecting rod 404 up. The other end of the connecting rod 404 pulls or pushes the transmission plate 405. The transmission plate 405 slides along the inner wall of the slide groove 2 on one side of the tool holder 1 through the second connecting block 406, thereby flexibly changing the spacing between the four sets of cutting tool bodies 3 and adjusting the outer diameter of the cutting tool body 3.

[0026] In addition, the rake face 301 of the cutting tool body 3 facilitates the feed of the tool set, the flank face 302 facilitates the retraction of the tool set, the extension rod 303 can minimize the collision between the tool holder 1 and the welded pipe, and the cutting tool body 3 is connected to the mounting groove 407 on the side of the transmission plate 405 through the mounting block 304 on one side of the extension rod 303.

[0027] Reference Figure 4 A pressure plate 5 is provided on one side of the transmission plate 405. One side of the pressure plate 5 abuts against one side of the mounting block 304. A fixing bolt 6 is inserted into the inner cavity of the pressure plate 5 and the inner cavity of the transmission plate 405. Through the pressure plate 5, one side of the mounting block 304 can be sealed. The pressure plate 5, together with the fixing bolt 6, can compact one side of the mounting block 304 to ensure the firmness of the cutting tool body 3.

[0028] Reference Figure 1 and Figure 5A push rod 7 is fixedly connected to the inner wall of the transmission sleeve 402. The surface of the push rod 7 is slidably connected to the inner wall of the connecting end 401 and the tool holder 1. A threaded rod 8 is rotatably connected to the inner cavity of the tool holder 1. An adjusting handle 9 is fixedly connected to one end of the threaded rod 8. The surface of the threaded rod 8 is threadedly connected to the inner cavity of the push rod 7. Through the push rod 7, the cutting tool body 3 can be adjusted from the outside of the tool holder 1 through the adjusting handle 9. The adjusting handle 9 can drive the threaded rod 8 to rotate. Since the surface of the threaded rod 8 is threadedly connected to the inner cavity of the push rod 7, the rotation of the threaded rod 8 can drive the push rod 7 to rise and fall. The rise and fall of the push rod 7 pushes the transmission sleeve 402 to rise and fall.

[0029] In addition, the adjusting handle 9 can be connected to an external transmission device to realize the automatic rotation of the adjusting handle 9.

[0030] Reference Figure 4 A limiting plate 408 is fixedly connected to the surface of the connecting end 401. The surface of the limiting plate 408 is slidably connected to the inner cavity of the transmission sleeve 402. Through the limiting plate 408, the transmission sleeve 402 will slide along the surface of the connecting end 401 due to the rise and fall of the push rod 7 under the action of the threaded rod 8. The limiting plate 408 can increase the friction between the transmission sleeve 402 and the connecting end 401 and limit the direction of rotation of the transmission sleeve 402, thereby improving the stability of the transmission sleeve 402 and the connected cutting tool body 3.

[0031] Working principle: The tool holder 1 serves as the main connector. The adjusting handle 9 can be connected to an external transmission device to achieve automatic rotation of the adjusting handle 9. The adjusting handle 9 can drive the threaded rod 8 to rotate. Since the surface of the threaded rod 8 is threadedly connected to the inner cavity of the push rod 7, the rotation of the threaded rod 8 can drive the push rod 7 to rise and fall. The rise and fall of the push rod 7 simultaneously pushes the transmission sleeve 402 to rise and fall. The transmission sleeve 402 can slide up and down along the surface of the connecting end 401. The rise and fall of the transmission sleeve 402 can also drive the first connecting block 403 to move together. When the first connecting block 403 rises and falls, it can pull down or push the connecting rod up. 404. The other end of the connecting rod 404 pulls or pushes the transmission plate 405. The transmission plate 405 slides along the inner wall of the groove 2 on one side of the tool holder 1 through the second connecting block 406, thereby flexibly changing the spacing between the four sets of cutting tool bodies 3 and adjusting the outer diameter of the cutting tool body 3. The front face 301 of the cutting tool body 3 is conducive to the tool group's feed, and the back face 302 is conducive to the tool group's retraction. The extension rod 303 can minimize the collision between the tool holder 1 and the welded pipe. The cutting tool body 3 is connected to the mounting groove 407 on one side of the transmission plate 405 through the mounting block 304 on one side of the extension rod 303.
