[0035] Specifically, in the existing pipeline inner wall polishing process, the metal dust generated by polishing slides along the inner wall of the pipeline to the bottom wall, which will have many adverse effects on the polishing operation itself. On the one hand, the metal dust that slides will re-attach to the polished area, obscuring the polishing marks, making it difficult for the operator to accurately judge the polishing effect, which may lead to insufficient or excessive polishing in local areas, affecting the flatness and smoothness of the pipeline inner wall, and reducing the polishing quality.

[0036] On the other hand, the metal dust accumulated on the bottom wall of the pipeline will hinder the smooth movement of the polishing tool, increase the polishing resistance, not only reduce the polishing efficiency, but also may cause uneven force on the polishing tool, accelerate the wear and damage of the tool, shorten its service life, increase the cost of equipment replacement and maintenance, and these dust may also interfere with the line of sight during polishing, causing inconvenience to the operator, increasing the difficulty and safety risk of the operation.

[0037] Therefore, the present application is set according to the above problems, first, one end of the metal pipe to be polished is clamped between the limiting groove formed between the limiting ring and the limiting plate, then the first guide rail is started, the sliding table below the limiting plate is moved, and the other sliding table is approached, so that the other end of the metal pipe is clamped between the connecting ring groove on one side of the positioning ring, thereby completing the limiting of the metal pipe. At this time, the polishing wheel is also inserted into the inner wall of the metal pipe, the motor is started, the rotation of the motor drives the positioning gear to rotate, the rotation of the positioning gear drives the rotating gears to rotate, the rotation of the rotating gears drives the gear ring engaged therewith to rotate, the rotation of the gear ring drives the polishing wheel engaged with the circumference to rotate, thereby enabling the polishing wheel to polish the inner wall of the pipeline. While the polishing wheel is polishing, the first hydraulic cylinder is started to push the polishing wheel gradually into the inner wall of the pipeline, and the entire inner wall of the pipeline is polished. During the polishing process, the adsorption roller made of polyester fiber material is rotatably arranged in the arc-shaped groove of the polishing wheel circumference, so that the metal dust generated during polishing can be adhered to prevent the dust from accumulating on the inner wall of the pipeline, affecting the polishing quality of the polishing wheel, and avoiding the interference of the metal dust with the movement of the polishing wheel.

[0038] The metal pipe is limited by the limiting ring, the limiting plate and the positioning ring, ensuring stable polishing, the motor drives the polishing wheel to rotate, and the first hydraulic cylinder is pushed to realize comprehensive polishing. At the same time, the adsorption roller made of polyester fiber material on the polishing wheel can effectively adhere to the metal dust generated during polishing, avoid the accumulation of dust affecting the polishing quality and interfering with the movement of the polishing wheel, and improve the polishing effect and efficiency.

[0039] For example, Figure 8 And Figure 9As shown, the circumferential surface of the gear ring of the embodiment is provided with a plurality of clamping grooves, the inner wall of the clamping groove is provided with a clamping piece, the inner wall of the polishing wheel is fixedly connected with a plurality of clamping plates, and the two ends of each clamping plate are provided with a clamping groove. The clamping groove can be clamped with the clamping piece; the clamping piece comprises a first groove body provided on the inner wall of the clamping groove, a compression spring is fixedly connected to the inner wall of the first groove body, one end of the compression spring is fixedly connected with a plug, the bottom wall of the clamping groove is provided with a second groove body, a spring is fixedly connected in the second groove body, and the top end of the spring is fixedly connected with a protrusion. A plug is also provided on one side of the protrusion, and the two plugs are inserted into the grooves on the two sides of the clamping plate.

[0040] Specifically, before polishing, the clamping plates on the inner wall of the polishing wheel are aligned with the clamping grooves on the circumferential surface of the gear ring, the clamping plates are slid into the clamping grooves, the clamping plates press the protrusions, the protrusions move into the second groove body, the springs are compressed, and the end of the clamping plate is inserted with the plug. When the grooves on the two sides of the clamping plate move to the corresponding position of the plug, the plug is inserted into the groove under the elastic force of the compression spring and the spring, the clamping and fixing of the polishing wheel and the gear ring are completed, when disassembling, the protrusion is pressed inward, the protrusion is retracted into the second groove body, the protrusion is removed, and then the polishing wheel is slid out, so that the polishing wheel can be taken out.

[0041] This clamping structure makes the installation and disassembly of the polishing wheel very convenient, can quickly complete the replacement, saves time, improves work efficiency, the compression spring and the spring provide stable elastic force, ensure that the plug is tightly clamped with the groove, the polishing wheel is firmly connected with the gear ring when rotating at high speed to polish the inner wall of the pipeline, and will not be loose or fall off, so as to ensure that the polishing work is stable and improve the polishing quality and safety.

[0042] Embodiment two: as shown in Figures 1 to 9 Compared with embodiment one, another embodiment of the application is: the pretreatment assembly further comprises a rotating block slidingly arranged on the circumferential surface of the reciprocating screw, a telescopic pipe is connected between the rotating block and the positioning disc, two connecting rods are fixedly connected to one side of the rotating block, an auxiliary roller is fixedly connected to the end of each connecting rod, the auxiliary roller is used for spraying cooling liquid on the inner wall of the pipeline and the inner wall of the gear ring, an adding opening is formed in the circumferential surface of the positioning disc, two positioning rods are fixedly connected to one side of the storage box, one end of the two positioning rods is fixedly connected with the same positioning ring, a connecting ring groove is formed in one side of the positioning ring, an adding groove corresponding to the adding opening is formed in the inside of the positioning ring, the adding opening and the adding groove are both in the shape of a nozzle and are connected after being pressurized.

[0043] Specifically, when the grinding wheel is rotating for grinding work, the rotation of the rotating gear drives the reciprocating screw rod fixedly connected thereto to rotate, the rotation of the reciprocating screw rod drives the rotating block slidingly connected to the circumferential surface thereof to slide along the reciprocating screw rod, and the rotating block pushes the auxiliary roller on one side thereof to move toward one side of the gear ring, so that the gear ring inner wall range can be moved. When the auxiliary roller moves, the pressurizing pump on the inner wall of the positioning disc pressurizes the cooling liquid in the interior, so that the cooling liquid is sprayed out of the auxiliary roller spray port to adhere to the metal dust on the inner wall of the gear ring. When the auxiliary roller moves out of the inner wall of the gear ring, the spray port pre-sprays the inner wall of the pipeline to cool the dust generated during grinding, so that the dust is adhered to the cooling liquid, the dust flying is reduced, the grinding quality is improved, and then when the cooling liquid in the positioning disc is sprayed out, the first hydraulic cylinder drives the positioning disc to retreat and abut against the positioning ring, the filling port is aligned with the filling groove, the pressure pump in the storage tank pressurizes to pressurize the cooling liquid in the storage tank to the positioning ring along the positioning rod, the cooling liquid in the positioning ring is extruded and sprayed out of the filling groove to impact the filling port, so that the cooling liquid is supplemented into the positioning disc, the heat generated during grinding is effectively reduced, the deformation of the pipeline and the gear ring caused by high temperature is reduced, the service life is prolonged, meanwhile, the cooling liquid can play a lubricating role, the friction between the grinding wheel and the inner wall of the pipeline is reduced, the grinding efficiency and quality are improved, the positioning disc can be automatically supplemented after the cooling liquid is used up, manual frequent operation is not needed, manpower and time are saved, continuous and stable operation of the equipment is ensured, and the overall production efficiency is improved.

[0044] The working principle is that first, one end of the metal pipeline to be ground is clamped between the limiting slots formed between the limiting ring and the limiting plate, and then the first guide rail is started to move the sliding table below the limiting plate to move close to the other sliding table, so that the other end of the metal pipeline is clamped between the connecting ring slots on one side of the positioning ring, thereby completing the limiting of the metal pipeline. At this time, the grinding wheel is also inserted into the inner wall of the metal pipeline. The motor is started, the rotation of the motor drives the positioning gear to rotate, the rotation of the positioning gear drives the rotating gears to rotate, the rotation of the rotating gears drives the gear ring engaged therewith to rotate, the rotation of the gear ring drives the grinding wheel clamped on the circumferential surface thereof to rotate, so that the grinding wheel performs the grinding work on the inner wall of the pipeline. While the grinding wheel is grinding, the first hydraulic cylinder is started to push the grinding wheel to gradually penetrate into the inner wall of the pipeline to grind the entire inner wall of the pipeline. During the grinding process, the arc-shaped groove in the circumferential surface of the grinding wheel is provided with an adsorbing roller made of polyester fiber and rotating in the arc-shaped groove. Therefore, the metal dust generated on the inner wall of the pipeline can be adhered while grinding to prevent the dust from accumulating on the inner wall of the pipeline and affecting the grinding quality of the grinding wheel, and the movement of the grinding wheel is not disturbed by the metal dust.

[0045] The metal pipeline is limited by the limiting ring, the limiting plate and the positioning ring, etc., to ensure stable polishing, the motor drives the polishing wheel to rotate, and the first hydraulic cylinder is pushed to realize overall polishing. Meanwhile, the adsorption roller made of polyester fiber material on the polishing wheel can effectively adhere to the metal dust generated during polishing, avoiding dust accumulation affecting the polishing quality and interfering with the movement of the polishing wheel, thereby improving the polishing effect and efficiency.

[0046] In addition, before polishing, the clamping plate on the inner wall of the polishing wheel is aligned with the clamping groove on the circumferential surface of the gear ring, the clamping plate is slid into the clamping groove, the clamping plate extrudes the protrusion, the protrusion moves into the second groove body, the spring is compressed, and the end of the clamping plate is inserted into the block. When the insertion grooves on both sides of the clamping plate move to the corresponding position of the block, the block is inserted into the insertion groove under the elastic force of the compression spring and the spring, the clamping of the polishing wheel and the gear ring is completed, and the clamping is fixed. When disassembling, press the protrusion inward to make the protrusion retract into the second groove body, remove the limiting and shielding of the protrusion on the polishing wheel, and then slide out the polishing wheel. The polishing wheel can be removed.

[0047] This clamping structure makes the installation and disassembly of the polishing wheel extremely convenient, can quickly complete replacement, saves time, improves work efficiency, the compression spring and the spring provide stable elastic force, ensures that the block is tightly clamped with the insertion groove, and the polishing wheel is firmly connected with the gear ring during high-speed rotation and polishing of the inner wall of the pipeline, and will not loosen or fall off, ensuring stable polishing work and improving polishing quality and safety.

[0048] When the polishing wheel rotates and polishes, the rotation of the rotating gear drives the reciprocating screw fixedly connected thereto, the rotation of the reciprocating screw drives the rotating block slidingly connected to the circumferential surface thereof, the rotating block slides along the reciprocating screw and pushes the auxiliary roller on one side thereof to move toward one side of the gear ring, so that the inner wall of the gear ring can be moved. At the same time that the auxiliary roller moves, the pressurizing pump in the inner wall of the positioning disc pressurizes the cooling liquid in the interior, so that the cooling liquid is sprayed from the auxiliary roller spray port, adheres to the metal dust on the inner wall of the gear ring, and when the auxiliary roller moves out of the inner wall of the gear ring, the spray port cools and pre-sprays the inner wall of the pipeline, so that the dust generated during polishing is adhered to the cooling liquid, reducing dust flying and improving polishing quality. Then, when the cooling liquid in the positioning disc is sprayed, the first hydraulic cylinder drives the positioning disc to retract and butt joint with the positioning ring, the filling port is aligned with the filling groove, the pressure pump in the storage tank pressurizes the cooling liquid in the storage tank to the positioning ring along the positioning rod, the cooling liquid in the positioning ring is extruded and sprayed into the filling groove and then impacts the filling port, so that the cooling liquid is supplemented into the positioning disc, effectively reducing the heat generated during polishing, reducing the deformation of the pipeline and the gear ring caused by high temperature, prolonging the service life, and at the same time, the cooling liquid can play a lubricating role, reducing the friction between the polishing wheel and the inner wall of the pipeline, improving the polishing efficiency and quality. The positioning disc can automatically butt joint with the positioning ring for replenishment after the cooling liquid is used up, without frequent manual operation, saving manpower and time, ensuring continuous and stable operation of the equipment, and improving overall production efficiency.

[0049] The foregoing merely illustrates the principles of the application and application of its more prominent features. Those skilled in the art will appreciate that the application is not limited to the embodiments described and illustrated and that many changes and modifications will occur to them without departing from the spirit and scope of the present application.
