Description

Technical Field

[0001] This invention belongs to the field of polishing technology, and in particular relates to a stainless steel pipe processing device. Background Technology

[0002] Stainless steel pipe processing equipment is a specialized industrial device for grinding and polishing stainless steel pipe workpieces. This equipment mainly removes defects such as burrs, oxide layers, and scratches from stainless steel pipes, improving surface smoothness, flatness, or roughness, while meeting the requirements of subsequent processing or usage scenarios.

[0003] Currently, when polishing stainless steel pipes, they are usually fixed on polishing equipment so that they come into contact with the grinding rollers before polishing. However, the drawback of the existing technology is that the grit of the grinding rollers cannot be changed during the polishing process. Manually changing the grit of the grinding rollers wastes a lot of manpower and resources and may also affect the production schedule. Moreover, in the process of batch polishing, it may be possible for the inner and outer walls of multiple batches of stainless steel pipes to fail to meet the smoothness standard, resulting in a large number of defective products that need to be reworked multiple times, thus greatly increasing the processing cost of stainless steel pipes.

[0004] Therefore, it is urgent to improve the polishing equipment used for stainless steel pipe processing in order to solve the above-mentioned problems. Summary of the Invention

The rotation of the switching wheel aligns several grinding rollers with the grinding groove one by one. The pressing drive mechanism and the clamping and pushing mechanism cooperate to make the stainless steel pipe to be processed repeatedly contact the grinding rollers with different grit sizes.

[0018] This invention has at least the following beneficial effects:

[0019] 1. In this invention, the grit number of the grinding rollers on the switching wheel gradually increases. The dual-shaft motor drives the grinding rollers to rotate via a belt, and drives the switching wheel to rotate via the motor. The rotation of the switching wheel aligns several grinding rollers with the grinding groove one by one.

[0020] 2. The present invention drives the cylinder to rotate the feeding plate through the meshing of the rack and gear. When the feeding plate rotates to the top, it can support the stainless steel tube and make it contact the grinding roller to prevent the stainless steel tube from slipping off during the polishing process. After polishing, the feeding plate rotates to the bottom through the drive cylinder, so that the stainless steel tube falls through the discharge chute. No manual material handling is required, which greatly reduces the labor intensity of workers.

[0021] 3. The damping plate of the present invention, through the action of the damping spring, abuts against the damping teeth on the damping ring, which can prevent the switching wheel from shaking during the operation of the grinding roller, improve the stability of the stainless steel pipe polishing process, and help improve the polishing accuracy of the polishing device for stainless steel pipe processing.

[0022] 4. The material collection box and the box cover of the present invention are rotatably connected by a connecting rod. The box cover extends to the bottom of the polishing groove. After the stainless steel tube is polished, it falls from the discharge groove onto the box cover. The box cover has a certain inclination, so the stainless steel tube can roll down the inclination of the box cover into the inside of the material collection box, preventing the stainless steel tube from falling to the outside of the material collection box.

[0045] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0046] like Figures 1-11 As shown, the stainless steel pipe inner and outer wall polishing equipment provided in this embodiment has a fixed stand 3 fixedly installed on one side of the lathe 1. A switching wheel mounting sleeve 301 is fixedly installed inside the fixed stand 3. Several evenly distributed damping plate rotating grooves 302 are opened on the outer side of the switching wheel mounting sleeve 301. A damping plate 303 is rotatably connected inside the damping plate rotating groove 302 through a hinge. A grinding roller conversion mechanism 4 is fixedly installed inside the fixed stand 3. Several evenly distributed fixed frames 5 are fixedly installed on the grinding roller conversion mechanism 4. Grinding rollers 6 are rotatably arranged on the fixed frames 5. The mesh count of the grinding rollers 6 gradually increases.

[0047] The grinding roller conversion mechanism 4 includes a motor 401 and a switching wheel 402. The switching wheel 402 has several evenly distributed grooves 403. A fixing frame 5 is fixedly mounted on the grooves 403 by bolts. The grinding roller conversion mechanism 4 has several evenly distributed heat dissipation windows 404. Damping rings 405 are fixedly installed on both sides of the grinding roller conversion mechanism 4. Several damping teeth 406 are provided on the inner side of the damping rings 405, corresponding to the damping plates 303. A limiting groove 304 is provided on the side of the fixing frame 3 away from the motor 401. Four extension rods are fixedly installed on the shaft of the switching wheel 402. The telescopic sleeve 407 has a limiting rod 408 slidably installed inside by a spring. The limiting rod 408 corresponds one-to-one with the grinding roller 6 and corresponds to the limiting groove 304. The four limiting rods 408 abut against the four corners of the limiting groove 304. The damping tooth 406 cooperates with the damping plate 303 to prevent the switching wheel 402 from rotating clockwise. The limiting rod 408 cooperates with the limiting groove 304 to prevent the switching wheel 402 from rotating counterclockwise. In addition, the limiting rod 408 is fitted with a spring to buffer the switching wheel 402 and prevent the rotational inertia of the switching wheel 402 from damaging the limiting rod 408.

[0048] A dual-axis motor 7 is fixedly installed inside the heat dissipation window 404. The output end of the dual-axis motor 7 extends to both sides of the grinding roller conversion mechanism 4 and is rotatably connected to a belt 8. The end of the belt 8 away from the dual-axis motor 7 is rotatably connected to the grinding roller 6 through a pulley. A clamping drive mechanism 9 is slidably arranged on the lathe 1, which corresponds to the grinding roller 6. A clamping and pushing mechanism 10 is slidably arranged on one side of the lathe 1, which corresponds to the grinding groove 2. The dual-axis motor 7 drives the grinding roller 6 to rotate through the belt 8, and drives the switching wheel 402 to rotate through the motor 401. The rotation of the switching wheel 402 makes several grinding rollers 6 align with the grinding groove 2 one by one. The clamping drive mechanism 9 and the clamping and pushing mechanism 10 cooperate to make the stainless steel pipe to be processed repeatedly contact the grinding roller 6 with different grit numbers, realizing the purpose of changing the grit number of the grinding roller 6 during the polishing process, thereby greatly improving the processing quality of the stainless steel pipe and thus greatly reducing the processing cost of the stainless steel pipe.

[0049] Specifically: When the motor 401 is started, the switching wheel 402 rotates, and the grinding rollers 6 with different grit sizes come into contact with the grinding groove 2 in sequence, achieving the purpose of quickly switching between different grit grinding rollers 6 for polishing. During the rotation of the switching wheel 402, the damping teeth 406 cooperate with the damping plate 303 to prevent the switching wheel 402 from rotating clockwise. When the grinding roller 6 is aligned with the grinding groove 2, the limiting rod 408 is stopped by the four slots of the limiting groove 304 through the spring, preventing the switching wheel 402 from rotating counterclockwise. While buffering the inertia of the switching wheel 402, it can also improve the stability of the grinding roller switching mechanism 4.

[0050] Furthermore, such as Figures 1-11 As shown, the grinding groove 2 has a fixed groove 201 and a discharge groove 202. The grinding roller 6 and the pressing drive mechanism 9 are respectively arranged on both sides of the fixed groove 201. The lathe 1 has a drive cylinder 203 fixedly installed on the outside of the grinding groove 2. A rack 204 is fixedly installed on the output end of the drive cylinder 203. The rack 204 passes through the grinding groove 2 and extends into the interior of the grinding groove 2. The discharge groove 202 has a discharge plate 205 rotatably arranged inside through a shaft. A gear 206 is fixedly connected to one end of the shaft. The rack 204 meshes with the gear 206, and the drive cylinder 203 drives the feeding plate 205 to rotate through the meshing of the rack 204 and the gear 206. When the feeding plate 205 rotates to the top, it can support the stainless steel tube and make it contact the grinding roller 6 to prevent the stainless steel tube from slipping during the polishing process. After polishing, the feeding plate 205 rotates to the bottom through the drive cylinder 203, so that the stainless steel tube falls through the discharge chute 202. There is no need for manual material handling, which greatly reduces the labor intensity of workers.

[0051] Furthermore, such as Figures 1-11 As shown, a damping spring 305 is fixedly installed inside the damping plate rotation groove 302. The end of the damping spring 305 away from the damping plate rotation groove 302 is fixedly connected to the damping plate 303. A polishing agent addition port is opened at the upper end of the fixed bracket 3. The polishing agent addition port corresponds to the grinding roller 6. The damping spring 305 is used to drive the damping plate 303 to abut against the damping tooth 406, thereby improving the stability of the switching wheel 402 in the clockwise direction. The polishing agent addition port makes it convenient to add polishing agent to the grinding roller 6 in advance. Adding polishing agent when polishing is not required is beneficial to improving the safety of the polishing device.

[0052] At the same time, such as Figures 1-11As shown, the two sides of the switching wheel 402 are fixedly connected to the output end of the motor 401 via shafts. The shafts are rotatably set inside the switching wheel mounting sleeve 301. A connecting rod 409 is rotatably connected to the inner side of the limiting rod 408. The end of the connecting rod 409 away from the limiting rod 408 is rotatably connected to the shaft of the switching wheel 402. The connecting rod 409 can prevent the limiting rod 408 from breaking during the rotation of the limiting groove 304. When the switching wheel 402 rotates counterclockwise, the limiting rod 408 will retract to a certain extent. The connecting rod 409 is used to pull the limiting rod 408. When the limiting rod 408 retracts to a certain extent, it will enter the groove on the other side of the limiting groove 304 through the pull of the connecting rod 409. Therefore, the switching wheel 402 can not only rotate, but also automatically point. This is more reliable than the existing method of increasing rotational friction to maintain stability. It makes the docking of the grinding roller 6 and the grinding groove 2 more secure, improves the stability of the stainless steel pipe polishing process, and also improves the polishing accuracy of the stainless steel pipe inner and outer wall polishing equipment.

[0053] Furthermore, such as Figures 1-11 As shown, several mounting posts 501 are fixedly installed on one side of the fixed frame 5, and the mounting posts 501 correspond to the grooves 403. A tripod 502 is fixedly installed on the side of the fixed frame 5 away from the mounting posts 501. The grinding roller 6 is rotatably installed inside the fixed frame 5 via a shaft, which facilitates the replacement of the grinding roller 6. Four fixed frames 5 are fixedly installed on the grinding roller conversion mechanism 4, which can replace the grinding roller 6 on the other side during the operation of the stainless steel pipe inner and outer wall polishing equipment. This greatly improves the maintenance and upkeep efficiency of the stainless steel pipe inner and outer wall polishing equipment, and allows for timely detection and correction of problems, thereby greatly improving the flexibility of the stainless steel pipe inner and outer wall polishing equipment.

[0054] Furthermore, such as Figures 1-11As shown, two sliding rails 101 are fixedly installed on the lathe 1. The clamping drive mechanism 9 is slidably disposed on the upper side of the lathe 1 via the sliding rails 101. An elastic telescopic rod 11 is fixedly installed between the two sliding rails 101, and the output end of the elastic telescopic rod 11 is fixedly connected to the clamping drive mechanism 9. The clamping drive mechanism 9 includes a slide plate 901, a second motor 902, and a clamping roller 903. The slide plate 901 is slidably disposed on the sliding rails 101. The second motor 902 is fixedly installed on the upper end of the slide plate 901. The clamping roller 903 is rotatably disposed on the slide plate 901. A gearbox 904 is fixedly installed on the slide plate 901. The gearbox 904 is a current... The technology is described in detail here. The output end of motor 2 902 passes through gearbox 904 and extends to the outside of gearbox 904. Belt 2 905 is rotatably installed at the output end of motor 2 902. The end of belt 2 905 away from slide plate 901 is rotatably connected to pressure roller 903 through pulley. Elastic telescopic rod 11 is used to drive slide plate 901 to slide on slide rail 101. Motor 2 902 is used to drive pressure roller 903 to rotate. During operation, pressure roller 903 can fit as close as possible to the surface of stainless steel pipe through the resilience of elastic telescopic rod 11, thereby greatly improving the applicability of stainless steel pipe inner and outer wall polishing equipment.

[0055] At the same time, such as Figures 1-11 As shown, an electric telescopic rod 12 is fixedly installed on the lathe 1. The clamping and pushing mechanism 10 includes a support plate 1001, a motor 1002, and a push block 1003. A slide rod 1004 is fixedly installed at the bottom of the support plate 1001. The slide rod 1004 is slidably disposed inside the lathe 1. The output end of the electric telescopic rod 12 is fixedly connected to the support plate 1001 through a fixing block. The motor 1002 is fixedly installed on the support plate 1001. The push block 1003 is fixedly connected to the output end of the motor 1002. The push block 1003 corresponds to the grinding groove 2. A three-toed pneumatic gripper 1005 is slidably disposed on the push block 1003. The three-toed pneumatic gripper 1005 is used for clamping and pushing stainless steel tubes. The three-toed pneumatic gripper 1005 is existing technology and will not be described in detail here. The contact area between the three-toed pneumatic gripper 1005 and the stainless steel tube is made of rubber material, which can prevent the stainless steel tube from being pinched and play an anti-slip role. The motor 1002 is used to drive the push block 1003 to rotate.

[0056] In addition, such as Figures 1-11As shown, a material collection box 13 is fixedly installed below the lathe 1. A box cover 1302 is rotatably connected to one side of the material collection box 13 via a support rod 1301. The box cover 1302 extends below the grinding groove 2. After the stainless steel tube is polished, it falls from the discharge groove 202 onto the box cover 1302. The box cover 1302 is made of rubber, which can buffer the impact of the falling stainless steel tube and prevent the stainless steel tube from being scratched or deformed. The box cover 1302 has a certain inclination, so the stainless steel tube can roll down the inclination of the box cover 13 into the inside of the material collection box 13, preventing the stainless steel tube from falling to the outside of the material collection box 13.

[0057] The shaft is existing technology and will not be described in detail here, nor is it shown in the figure.

[0058] like Figures 1-11 As shown in the figure, the principle of the stainless steel pipe processing device provided in this embodiment is as follows:

[0059] A fixed support 3 is fixedly installed on one side of the lathe 1. A grinding roller conversion mechanism 4 is fixedly installed inside the fixed support 3. Several evenly distributed fixed brackets 5 are fixedly installed on the grinding roller conversion mechanism 4. Several evenly distributed damping plate rotation slots 302 are opened on the outer side of the switching wheel mounting sleeve 301. Damping plates 303 are rotatably connected to the inside of the damping plate rotation slots 302 via hinges. The grinding roller conversion mechanism 4 is fixedly installed inside the fixed support 3. Several evenly distributed fixed brackets 5 are fixedly installed on the grinding roller conversion mechanism 4. Grinding rollers 6 are rotatably mounted on the fixed brackets 5. The mesh size of the grinding rollers 6 gradually increases. The fixed brackets 5 are fixedly installed on the grooves 403 by bolts. Damping teeth 406 correspond to damping plates 303. Limiting rods 408 correspond one-to-one with grinding rollers 6 and correspond to limiting grooves 304. The four limiting rods... The four corners of the control rod 408 and the limiting groove 304 abut against each other. The damping teeth 406 and the damping plate 303 cooperate to prevent the switching wheel 402 from rotating clockwise. The limiting rod 408 and the limiting groove 304 cooperate to prevent the switching wheel 402 from rotating counterclockwise. A spring is sleeved on the limiting rod 408 to buffer the switching wheel 402 and prevent the rotational inertia of the switching wheel 402 from damaging the limiting rod 408. The switching wheel 402 is driven to rotate by the motor 401. The rotation of the switching wheel 402 causes several grinding rollers 6 to align with the grinding groove 2 one by one. The pressing drive mechanism 9 and the clamping and pushing mechanism 10 cooperate to make the stainless steel pipe to be processed repeatedly contact the grinding rollers 6 with different grits. This achieves the purpose of changing the grit of the grinding rollers 6 during the polishing process, thereby greatly improving the processing quality of the stainless steel pipe and thus greatly reducing the processing cost of the stainless steel pipe.
