[0002] Stainless steel square tubes are a type of pipe with high strength and corrosion resistance. They are widely used in industrial, construction and medical fields. Specifically, they can be used to make conveying pipelines, stair handrails, window guards, railings, road partitions and so on. In order to remove the burrs on stainless steel square tubes, burr removal equipment is required.

[0003] In actual use, burrs on the outer surface of stainless steel square tubes can generally be easily removed by manual grinding, but burrs on the inner wall of stainless steel square tubes are difficult to remove effectively due to the limitations of tube length and grinding method, which in turn affects the grinding efficiency of the burr removal mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a burr removal mechanism for stainless steel square tubes to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A stainless steel square tube burr removal mechanism includes a base plate, a fixed box fixedly connected to the upper side of the base plate, a groove on one side of the fixed box, a bidirectional threaded rotating rod rotatably connected inside the fixed box via a first servo motor, two symmetrically arranged displacement blocks spirally sleeved on the bidirectional threaded rotating rod, a mounting bracket fixedly connected to one side of each of the two displacement blocks, a reinforcing plate fixedly connected to one end of each of the two mounting brackets, and a grinding block and a U-shaped grinding plate fixedly installed at both ends of the U-shaped vertical plate for moving in opposite directions.

[0007] Both reinforcing plates and mounting brackets have slots on one side, with insert plates inserted inside the slots.

A movable inner ring is rotatably connected inside the rotating groove. A gear ring is fixedly connected to one side of the movable inner ring. A fixed plate is arrayed and connected to the other side of the movable inner ring. A first bolt is threaded to one side of the fixed plate. One side of the first bolt passes through the fixed plate and extends to the other side of the fixed plate. A rotating shaft is rotatably connected to one side of the U-shaped vertical plate through a second servo motor. A drive gear that meshes with the gear ring is fixedly connected to the outer surface of the rotating shaft. The output shaft of the second servo motor is fastened to the rotating shaft.

[0009] Preferably, a pressure plate is fixedly connected to one side of the first bolt, two rubber strips arranged in an array are fixedly connected to one side of the pressure plate, and two parallel connecting rods are fixedly connected to the other side of the pressure plate. Two symmetrically arranged sliding grooves are provided on the fixed plate, and the outer surface of the connecting rod is slidably placed inside the sliding groove.

[0010] Preferably, the grinding block is attached to the upper part of the inner wall of the stainless steel square tube, the U-shaped grinding plate is attached to the upper part of the outer wall of the stainless steel square tube, and a collection box is placed in the middle of the upper side of the base plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6As shown, a stainless steel square tube burr removal mechanism includes a base plate 1, a fixed box 21 fixedly connected to the upper side of the base plate 1, a groove 22 opened on one side of the fixed box 21, a bidirectional threaded rotating rod 23 rotatably connected inside the fixed box 21 via a first servo motor, two symmetrically arranged displacement blocks 25 spirally sleeved on the bidirectional threaded rotating rod 23, and a mounting bracket 26 fixedly connected to one side of each of the two displacement blocks 25. The two displacement blocks 25 can drive the two mounting brackets 26 to move relative to each other or towards each other in the groove 22. At this time, the fixed box 21 can protect the bidirectional threaded rotating rod 23 and prevent burrs and debris from affecting the use of the bidirectional threaded rotating rod 23. A reinforcing plate 14 is fixedly connected to one end of each of the two mounting brackets 26, and a grinding block 15 and a U-shaped grinding plate 16 for moving towards each other are fixedly provided at both ends of the U-shaped vertical plate 2.

[0027] Each of the two reinforcing plates 14 and the mounting bracket 26 has a slot 17 on one side. The slot 17 is fitted with an insert plate 18. One side of the insert plate 18 is fastened to the U-shaped grinding plate 16. Both ends of the other insert plate 18 are fixedly connected to brackets 19. The two brackets 19 are fastened to the U-shaped grinding plate 16. The output shaft of the first servo motor is fastened to the bidirectional threaded rotating rod 23. The two sets of grinding blocks 15 and the U-shaped grinding plate 16 can form a double-sided synchronous grinding mechanism, which can quickly and effectively remove the burrs and rough edges from the outer surface and the upper part of the inner wall of the stainless steel square tube, significantly improving the overall grinding efficiency and work quality of the stainless steel square tube burr removal mechanism.

[0028] A U-shaped vertical plate 2 is fixedly connected to the upper center of the base plate 1. A rotating groove 3 is provided inside the U-shaped vertical plate 2. A movable inner ring 4 is rotatably connected inside the rotating groove 3. A gear ring 5 is fixedly connected to one side of the movable inner ring 4. A fixed plate 6 is arrayed and connected to the other side of the movable inner ring 4. A first bolt 7 is threadedly connected to one side of the fixed plate 6. One side of the first bolt 7 passes through the fixed plate 6 and extends to the other side of the fixed plate 6. A rotating shaft 12 is rotatably connected to one side of the U-shaped vertical plate 2 through a second servo motor. An active gear 13 that meshes with the gear ring 5 is fixedly connected to the outer surface of the rotating shaft 12. The output shaft of the second servo motor is fastened to the rotating shaft 12. The model of the servo motor is SMBL-60P.

[0029] A pressure plate 9 is fixedly connected to one side of the first bolt 7. Two rubber strips 10 arranged in an array are fixedly connected to one side of the pressure plate 9. Two parallel connecting rods 8 are fixedly connected to the other side of the pressure plate 9. Two symmetrically arranged sliding grooves 11 are opened on the fixing plate 6. The outer surface of the connecting rod 8 is slidably placed inside the sliding groove 11. When the two sets of grinding blocks 15 and the U-shaped grinding plate 16 move towards each other again, the outer surface and inner wall of the tube body that were originally in the lower position are ground a second time to ensure that the burrs in this area are completely removed. This step-by-step grinding process design realizes all-round treatment of the inside and outside of the stainless steel square tube.

[0030] The grinding block 15 is attached to the upper part of the inner wall of the stainless steel square tube, and the U-shaped grinding plate 16 is attached to the upper part of the outer wall of the stainless steel square tube. A collection box 27 is placed in the middle of the upper side of the base plate 1. When the two sets of grinding blocks 15 and U-shaped grinding plates 16 move relative to each other, burrs and debris can be pushed out. The collection box 27 can then be used to collect the burrs and debris that have been ground down.

[0031] The fixed box 21 is internally fixedly connected to a limiting rod 24, and the outer surface of the limiting rod 24 is slidably connected to the inside of the displacement block 25.

[0032] Two reinforcing plates 14 and mounting bracket 26 are each secured with a second bolt 20 for fixing the insert plate 18. The lower side of the second bolt 20 passes through the insert plate 18 and extends to the lower side of the insert plate 18. Nuts 28 are threaded onto the outer surface of all four second bolts 20. Both the bolts and nuts 28 use fine threads with a high thread density, resulting in stronger overall self-locking and ensuring stability during use. Then, the first bolt 7 is turned on top of one of the pressure plates 9 of the stainless steel square tube, and the pressure plate 9 is fixed to the left and right sides and top of the stainless steel square tube by the first bolt 7. The rubber strips 10 on the four pressure plates 9 can increase the friction with the stainless steel square tube to securely lock the stainless steel square tube.

[0033] The working principle of the stainless steel square tube burr removal mechanism provided by this utility model is as follows:

[0034] By sequentially inserting the insert plate 18 into the slot 17, the two sets of grinding blocks 15 and the U-shaped grinding plate 16 can be installed in the grinding position to adapt to grinding stainless steel square tubes of matching dimensions. Then, the second bolts 20 are inserted into the insert plate 18 until they are exposed. Next, the nut 28 is tightened so that it is threaded onto the second bolt 20 to lock the positions of the two sets of grinding blocks 15 and the U-shaped grinding plate 16. Then, the first servo motor is started, so that the output shaft of the first servo motor can start the dual... Rotate the threaded rod 23 so that the two displacement blocks 25 on the two-way threaded rod 23 can drive the two displacement blocks 25 on the two-way threaded rod 23 to move towards each other. At this time, the two sets of grinding blocks 15 and the U-shaped grinding plate 16 can simultaneously and effectively grind the outer surface and inner wall of both ends of the stainless steel square tube, so as to quickly remove the burrs on the outer surface and the upper part of the inner wall of the stainless steel square tube, thereby improving the grinding efficiency of the stainless steel square tube burr removal mechanism. At the same time, after the inner wall of the stainless steel square tube is ground, the debris will fall into the bottom of the stainless steel square tube, reducing the impact of debris on the grinding work.

[0035] By restarting the first servo motor, its output shaft can drive the bidirectional threaded rotor 23 to reverse, allowing the two displacement blocks 25 on the bidirectional threaded rotor 23 to move relative to each other. This enables the two sets of grinding blocks 15 and the U-shaped grinding plate 16 to grind the outer surfaces and inner walls of both ends of the stainless steel square tube again, allowing the two sets of grinding blocks 15 and the U-shaped grinding plate 16 to move out of the stainless steel square tube. Then, the second servo motor is restarted, allowing its output shaft to drive the drive gear 13 on the rotating shaft 12 to rotate. Subsequently, the drive gear... Gear 13 can drive the movable inner ring 4 on one side of gear ring 5 to rotate in rotating groove 3, allowing the stainless steel square tube to rotate 180 degrees. Then, the two sets of grinding blocks 15 and U-shaped grinding plates 16 move towards each other again to remove the burrs on the outer surface and the lower part of the inner wall of the stainless steel square tube, achieving comprehensive grinding of the outer surface and inner wall of the stainless steel square tube. Furthermore, the use of upper and lower staged grinding allows the debris to fall to the bottom of the stainless steel square tube, preventing debris from affecting the grinding process and ensuring that the burr removal work is carried out stably and reliably.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
