Description

Technical Field

[0001] This invention relates to the field of workpiece rotary surface grinding technology, and in particular to a fully automatic and efficient integrated machine for deburring and polishing stainless steel pipes. Background Technology

[0002] In the stainless steel pipe manufacturing and processing industry, surface deburring and polishing are key processes to ensure product quality and performance. Due to their excellent corrosion resistance and mechanical properties, stainless steel pipes are widely used in fields such as building decoration, machinery manufacturing, automotive industry, and medical devices. These applications have strict requirements for the surface finish, inner wall smoothness, and edge flatness of the steel pipes. End face burrs may cause assembly jamming or sealing failure, while rough inner walls will increase fluid resistance, breed bacteria, or aggravate media wear, directly affecting product service life and safety.

[0003] In traditional processing, deburring and polishing are often done in separate steps: end face deburring relies on manual handling with hand-held grinding wheels or scrapers, which is inefficient and the quality is greatly affected by the operator's skill; inner wall polishing uses simple grinding heads for manual pushing, which makes it difficult to ensure uniformity, especially for the inner walls of small-diameter pipes and long pipes, which are prone to missed polishing and over-polishing. Although some automated equipment can automate a single process, it has functional limitations: it can only process the end face and cannot handle the inner wall, and process switching requires manual intervention, resulting in poor production continuity and low batch processing consistency.

[0004] Furthermore, existing equipment lacks the capability to handle burrs on the rolled edges of the "end face-inner wall transition zone." This area, due to its complex structure, becomes a blind spot for traditional tools, easily leaving burrs that can cause problems in subsequent use. Simultaneously, high manual intervention leads to high labor intensity, rapid material consumption, and difficulty in meeting the stringent surface quality requirements of high-precision fields (such as medical and hydraulic systems). Therefore, developing a highly efficient processing equipment that can achieve fully automated integrated processing and cover the entire surface without blind spots has become an urgent need to address these industry pain points. Summary of the Invention

[0005] Given the existing technical problems such as low efficiency, poor quality stability, poor process connection, difficulty in covering processing dead corners such as end face and inner wall transition area, and high degree of manual intervention, which cannot meet the needs of high-precision fields for full surface treatment without dead corners, a fully automatic and efficient integrated deburring and polishing machine for stainless steel pipes was proposed.

[0006] Its purpose is to provide a device that integrates fully automatic feeding, precise positioning, and multi-area collaborative processing. Through the step-by-step positioning design of the rotating grinding plate and the adaptable polishing of the grinding wheel, it can achieve full-surface treatment without dead corners on the end face, inner side, and inner wall of stainless steel pipes, eliminate the process connection obstacles and drawbacks of manual intervention in traditional processing, and greatly improve processing efficiency and quality stability, so as to meet the stringent requirements of high-precision fields such as construction, medical, and hydraulic for the surface quality of stainless steel pipes.

[0007] The technical solution of the present invention is a fully automatic and efficient stainless steel pipe surface deburring and polishing integrated machine, including a machine body, an installation platform set on one side of the machine body, a polishing seat set on the operating platform, a drive mechanism set on one end of the operating platform, a feeding mechanism set on the side of the operating platform, a steel pipe body set in the feeding mechanism, a limiting mechanism set on the top of the polishing seat, and a working mechanism set on one side of the drive mechanism.

[0008] The working mechanism includes a grinding wheel disposed on one side of the drive mechanism, and the nominal diameter of the grinding wheel is slightly smaller than the nominal inner diameter of the steel pipe body. A burr removal assembly is annularly disposed on the side wall of the grinding wheel. The burr removal assembly includes a folding groove opened on the side wall of the grinding wheel, a rotating grinding plate disposed at one end of the folding groove, a rotating shaft disposed at the bottom of the rotating grinding plate, abutments symmetrically disposed at both ends of the rotating shaft, grooves respectively opened on both sides of the folding groove, and both ends of the rotating shaft and the abutments are disposed in the grooves, and a reset assembly disposed on one side of the grooves.

[0009] Furthermore, the driving mechanism is used to drive the working mechanism to remove burrs from the end face of one end of the steel pipe body and to polish the inner surface of the steel pipe body.

[0010] The feeding mechanism is used for feeding materials, and the limiting mechanism is used to limit the steel pipe body in conjunction with the polishing seat during polishing, so as to facilitate grinding and polishing.

[0011] The reset assembly is used to reset the grinding plate, which is used to grind and remove burrs from the end face of the steel pipe body, and the grinding wheel is used to polish the inner surface of the steel pipe body.

[0012] Furthermore, the groove assembly includes a movable groove formed on the inner wall of the folded groove, an arc-shaped groove formed at the bottom of one end of the movable groove, and an end face grinding point set in the middle of the movable groove.

[0013] Furthermore, the reset assembly includes a sliding groove on one side of the moving groove, a sliding block disposed in the sliding groove, a rotating groove on one side of the sliding block, a mounting groove on one side of the sliding groove, a spring disposed in the mounting groove, one end of the spring being fixedly connected to the sliding block, a rotating rod disposed at one end of the rotating shaft, and a torsion spring disposed between the rotating rod and the rotating groove, wherein the rotating rod is rotatably connected to the rotating groove.

[0014] Furthermore, steel balls are provided at the ends of several of the rotating grinding plates, with the steel balls protruding from one end of the rotating grinding plate.

[0015] Furthermore, the grinding plate has a straight surface on the side near the steel pipe body and an arc-shaped surface on the other side, and the two sides near the top straight surface of the grinding plate are thickened.

[0016] Furthermore, the limiting mechanism includes a cylinder disposed on one side of the machine body, a mounting block disposed at the bottom of the cylinder, a plurality of limiting wheels disposed at the bottom of the mounting block, and a positioning plate disposed on one side of the end limiting wheel. The positioning plate extends to the bottom of the limiting wheel and is used to abut one end of the steel pipe body during polishing.

[0017] Furthermore, one end of the steel pipe body protrudes from one side of the polishing seat.

[0018] Furthermore, when the rotating shaft moves to the end face grinding point, the straight surface of the grinding plate is exactly in contact with the end face of the steel pipe body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Achieve full-process automation and integrated procedures, significantly improving processing efficiency and quality stability. The equipment integrates functions such as feeding, limiting, deburring, polishing, and resetting, completing continuous processing of steel pipe end faces, inner edges, and inner walls without manual intervention. This avoids clamping errors and process waiting times associated with traditional step-by-step processing, resulting in a significant improvement in batch production efficiency. Through the multi-angle adaptation of the rotary grinding plate and the precise fit design of the grinding wheel, it comprehensively covers processing dead corners such as end face burrs, inner edge curls, and inner wall scratches, ensuring uniform processing quality for each steel pipe.

[0021] 2. The ingenious structural design combines processing precision with equipment durability. The step-by-step limiting and coordination of the groove assembly and the backing plate ensures that the grinding plate operates in an orderly manner along the trajectory of the edge, the entire end face, and the inner side. Combined with the straight-face contact, curved surface containment, and thickening treatment of the grinding plate, it not only ensures thorough burr removal but also reduces movement jamming and component wear. The spring and torsion spring of the reset assembly work together to achieve buffer protection during processing and precise reset after completion, reducing drive energy consumption and failure risk, and extending the service life of the equipment.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1, referring to Figures 1-11This invention provides a fully automatic and efficient integrated machine for deburring and polishing stainless steel pipes, comprising a machine body 1, a mounting platform 11 mounted on one side of the machine body 1, a polishing seat 12 mounted on the operating platform, a drive mechanism 13 mounted at one end of the operating platform, a feeding mechanism 14 mounted on the side of the operating platform, a steel pipe body placed in the feeding mechanism 14, a limiting mechanism 15 mounted on the top of the polishing seat 12, and a working mechanism mounted on one side of the drive mechanism 13. The drive mechanism 13 is used to drive the working mechanism to deburr the end face of one end of the steel pipe body and to polish the inner surface of the steel pipe body. The feeding mechanism 14 is used for feeding, and the limiting mechanism 15 is used to limit the steel pipe body in conjunction with the polishing seat 12 during polishing, forming a stable clamp on the steel pipe to avoid tool displacement due to vibration during processing, thus facilitating grinding and polishing. The working mechanism includes a grinding wheel 2 mounted on one side of the drive mechanism 13, wherein the nominal diameter of the grinding wheel 2 is slightly smaller than the nominal inner diameter of the steel pipe body, and the grinding wheel 2 is made of an abrasive material with a certain degree of elasticity (such as a resin-bonded grinding wheel). The outer diameter of the grinding wheel 2 can expand slightly (not exceeding 0.3mm) under its own elasticity and centrifugal force, allowing the sidewall of the grinding wheel to make effective contact with the inner wall of the steel pipe. Simultaneously, the actual diameter tolerance of the grinding wheel 2 is controlled within +0 / -0.2mm. When encountering a small tolerance (±0.2mm) in the inner diameter of the steel pipe, it can still ensure full circumferential grinding coverage through its own elastic compensation. The burr removal component 3 is annularly mounted on the sidewall of the grinding wheel 2. The burr removal component 3 includes a folded groove 31 formed on the sidewall of the grinding wheel 2. The rotating grinding plate 32 is installed at one end of the folding groove 31, the rotating shaft 33 is fixedly connected to the bottom of the rotating grinding plate 32, the abutment plates 34 are symmetrically fixedly connected to both ends of the rotating shaft 33, the groove groups 35 are respectively opened on both sides of the folding groove 31, and both ends of the rotating shaft 33 and the abutment plates 34 are set in the groove groups 35, and the reset component 4 is set on one side of the groove group 35; the reset component 4 is used to reset the rotating grinding plate 32, the rotating grinding plate 32 is used to grind and remove burrs from the end face of the steel pipe body, and the grinding wheel 2 is used to polish the inner surface of the steel pipe body.

[0037] Specifically, when deburring and polishing the steel pipe body, the feeding mechanism 14 places a steel pipe body onto the polishing seat 12, the limiting mechanism 15 is driven to move down and limit the top of the steel pipe body, and the random driving mechanism 13 pushes the working mechanism forward to deburr the end face of the steel pipe body first, and then polishes and grinds its inner surface. The drive mechanism 13 is equipped with a motor and a cylinder. While driving the working mechanism forward, it rotates, causing the grinding wheel 2 to rotate. Simultaneously, it drives several rotating grinding plates 32 to rotate. Initially, the rotating grinding plates 32 are tilted and contact the side of the end face of the steel pipe body for grinding. As the grinding wheel 2 is continuously pushed forward, the end face of the steel pipe body pushes the rotating grinding plates 32 to rotate. The rotating shaft 33 rotates in the groove group 35. When the rotating shaft 33 moves to a certain point in the groove group 35, the rotating grinding plate 32 is just in contact with the end face of the steel pipe body. At this time, the rotating grinding plate 32 continues to grind its end face for a period of time. Then, the rotating grinding plate 32 continues to rotate and grinds the inner side of the steel pipe body. Finally, the grinding wheel 2 enters the steel pipe body and polishes its inner wall. At the same time, the rotating grinding plate 32 rotates and retracts into the folding groove 31, thereby achieving deburring and polishing of the stainless steel pipe.

[0038] For the complex burr distribution on the inner surface and end face of stainless steel pipes (such as end face flash, inner side curling, and fine scratches on the inner wall), the equipment achieves comprehensive processing through the multi-angle adaptation of the rotating grinding plate 32. In the initial tilted state, it can contact the stubborn burrs on the edge of the end face. After rotation, it fits the end face to grind flat burrs. Continued rotation can grind the inner side curling (the dead corner at the junction of the end face and the inner wall), which solves the problem that traditional tools cannot take care of the transition area of ​​"end face and inner side". In addition, the diameter of the grinding wheel 2 is the same as the inner diameter of the steel pipe. After entering the pipe, it can fit the inner wall completely and achieve uniform polishing with the rotational motion, avoiding the problem of "incomplete polishing in the middle" of the inner wall of small diameter pipes.

[0039] Reference Figure 6 , Figure 8 and Figure 11 The groove assembly 35 includes a movable groove 351 formed on the inner wall of the folding groove 31, an arc-shaped groove 352 formed at the bottom of one end of the movable groove 351, and an end face grinding point 353 set in the middle of the movable groove 351.

[0040] Specifically, in the initial state, the abutment plate 34 on one side of the rotating shaft 33 is located in the moving groove 351. When the end face of the steel pipe body is ground and deburred, the rotating grinding plate 32 is squeezed by the end face of the steel pipe body, causing the rotating grinding plate 32 to drive the rotating shaft 33. At the same time, the reset component 4 is slightly stretched. When the abutment plate 34 rotates to abut the bottom wall of the moving groove 351, the rotating shaft 33 is located at the end face grinding point 353, and the abutment plate 34 is limited and no longer rotates, so that the rotating shaft 33 and the rotating grinding plate 32 can no longer rotate. At this time, one side of the rotating grinding plate 32 is in contact with the end face of the steel pipe body for grinding. As the grinding wheel 2 keeps moving forward, the rotating grinding plate 32 begins to continuously stretch the reset component 4, and the rotating shaft 33 continues to move in the moving groove 351. The end face of the steel pipe body is continuously and fully ground. When one side of the abutment plate 34 reaches the arc-shaped groove 352, the abutment plate 34 is no longer subject to abutment limitation, and the rotating grinding plate 32 begins to drive the rotating shaft 33 to rotate. The abutment plate 34 rotates within the arc-shaped groove 352, allowing the rotating grinding plate 32 to rotate and retract into the folding groove 31. This automatic retraction after removing the end face burrs avoids affecting the smooth entry of the grinding wheel 2 into the inner wall of the steel pipe during polishing. Through the cooperation of the groove group 35 and the abutment plate 34, the deburring process is "step-by-step precise control" is achieved, ensuring thorough burr removal. This "step-by-step limiting" design allows the rotating grinding plate 32 to cover all burr areas sequentially from the edge to the entire end face and inner side, ensuring no dead corners in deburring and guaranteeing the quality of burr removal.

[0041] Example 2, refer to Figures 6-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the reset component 4 includes a sliding groove 41 formed on one side of the moving groove 351, a sliding block 42 slidably connected in the sliding groove 41, a rotating groove 43 formed on one side of the sliding block 42, a mounting groove 44 formed on one side of the sliding groove 41, a spring 45 fixedly connected in the mounting groove 44, and one end of the spring 45 fixedly connected to the sliding block 42, a rotating rod 46 fixedly connected to one end of the rotating shaft 33, abutting against a torsion spring disposed between the rotating rod 46 and the rotating groove 43, and the rotating rod 46 rotatably connected to the rotating groove 43.

[0042] Specifically, when the abutment plate 34 rotates and moves within the moving groove 351, the rotating rod 46 rotates within the rotating groove 43 while simultaneously driving the sliding plate to move within the sliding groove 41, and the spring 45 is stretched. When the abutment plate 34 rotates and moves within the arc-shaped groove 352, the rotating rod 46 rotates while simultaneously driving the sliding block 42 to move. A torsion spring (not shown in the figure) provided between the rotating rod 46 and the rotating groove 43 provides a torsional restoring force. When polishing is completed and the grinding wheel 2 is removed, the inner wall of the steel pipe body no longer presses against the rotating grinding plate 32. At this time, the spring 45 and the torsion spring simultaneously reset, causing the abutment plate 34 to rotate and move, resetting within the moving groove 351, completing the reset of the rotating grinding plate 32, which facilitates deburring and polishing of the next steel pipe body. The synergistic elastic force of spring 45 and torsion spring ensures both buffer protection during processing and precise automatic reset after processing, solving the problems of "low efficiency of manual reset and poor reliability of electronic reset". Together with slot group 35, working mechanism, etc., it improves the batch processing capacity and long-term operation stability of the integrated machine.

[0043] Reference Figure 7 Several rotating grinding plates 32 have steel balls 5 rollingly connected to their ends, with the steel balls 5 protruding from one end of the rotating grinding plate 32.

[0044] Specifically, the steel balls 5 engage in rolling contact, which results in less resistance compared to the sliding friction where the grinding plate 32 directly contacts the end face or inner wall of the steel pipe. This not only reduces the power consumption of the drive mechanism 13 but also reduces wear on the end of the grinding plate 32 and the surface of the steel pipe, extending the service life of the grinding plate 32. Simultaneously, it reduces the risk of excessive scratching of the steel pipe surface, facilitates the resetting of the grinding plate 32, reduces frictional and grinding resistance, and enhances grinding efficiency.

[0045] Reference Figures 6-7 The grinding plate 32 has a straight surface on one side near the steel pipe body and an arc-shaped surface on the other side. The two sides of the straight surface near the top of the grinding plate 32 are thickened.

[0046] Specifically, the end face of the steel pipe body is flat. When the straight surface of the grinding plate 32 contacts it, a large area of ​​contact can be formed, avoiding localized missed grinding or uneven grinding problems caused by the curved contact surface. Especially when performing flat grinding on the end face, the straight surface can fully cover the end face area, ensuring that burrs (including edge burrs, end face protrusions, etc.) are completely removed. The curved surface and thickening treatment can enhance structural strength, improve durability and stability, and enhance resistance to deformation. The rest of the structure is the same as that in Example 1.

[0047] Example 3, referring to Figures 1-4This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the limiting mechanism 15 includes a cylinder fixedly connected to one side of the machine body 1, a mounting block fixedly connected to the bottom of the cylinder, a plurality of limiting wheels 6 disposed at the bottom of the mounting block, and a positioning plate 7 fixedly connected to one side of the end limiting wheel 6. The positioning plate 7 extends to the bottom of the limiting wheel 6 and is used to abut one end of the steel pipe body during polishing.

[0048] Specifically, the positioning plate 7 extends to the bottom of the limiting wheel 6 and abuts against one end of the steel pipe body, providing a clear axial reference for the steel pipe body and ensuring that the starting position of each steel pipe is uniform during polishing. This avoids uneven polishing depth of the inner wall or end face due to deviations in the placement of the steel pipe body (such as over-polishing in some areas and under-polishing in some areas), improving the consistency of batch processing. Several limiting wheels 6 form a circumferential constraint on the steel pipe from above, which, together with the axial limiting of the positioning plate 7, can firmly fix the steel pipe on the preset processing trajectory, reducing displacement caused by friction and vibration of the grinding wheel 2 during polishing, and ensuring that the polishing path accurately conforms to the inner wall of the steel pipe.

[0049] Reference Figure 3 One end of the steel pipe body protrudes from one side of the polishing seat 12.

[0050] Specifically, this facilitates the entry and grinding of several rotating grinding plates 32, avoiding interference.

[0051] Reference Figures 9-11 When the rotating shaft 33 moves to the end face grinding point 353, the straight surface of the rotating grinding plate 32 is exactly in contact with the end face of the steel pipe body.

[0052] Specifically, in direct contact, the grinding force is more stable in direction (perpendicular to the end face), allowing it to be applied precisely to the burr area. This reduces "grinding offset" caused by the tilt of the contact surface (such as over-grinding the edge of the end face or omitting the central area), improving the accuracy of deburring. Directional cutting reduces deviation, and continuous grinding improves grinding quality, resulting in more thorough burr removal. The remaining structure is the same as in Example 2.

[0053] Based on embodiments 1-3, the working principle of this invention is as follows: When the integrated machine is working, the feeding mechanism 14 sends the steel pipe body to the polishing seat 12. The cylinder of the limiting mechanism 15 drives the limiting wheel 6 to move down and cooperate with the positioning plate 7 to fix the steel pipe, ensuring axial and radial position stability. The driving mechanism 13 drives the working mechanism to move forward and rotate. In the initial state, the grinding plate 32 is inclined, the end steel ball 5 contacts the edge of the steel pipe end face, and the abutment plate 34 rotates in the moving groove 351 to remove edge burrs. As the grinding wheel 2 advances, the grinding plate 32 is continuously squeezed, the rotating shaft 33 moves along the moving groove 351, and when the abutment plate 34 abuts against the bottom wall of the moving groove 351, the grinding plate 32 is in direct contact with the end face of the steel pipe (located at the end face grinding point 353), continuously grinding the flat burrs, while stretching the spring 45 and torsion spring of the resetting assembly 4. The grinding wheel 2 continues to penetrate deeper, and the abutment plate 34 enters the arc-shaped groove 352. The rotating grinding plate 32 rotates and retracts into the folded groove 31, grinding the inner edge and making room. Then, the grinding wheel 2 (whose diameter matches the inner diameter of the steel pipe) enters the pipe and rotates to polish the inner wall. After polishing, the grinding wheel 2 retracts, the spring 45 and the torsion spring reset, and the rotating grinding plate 32 returns to its initial state, completing one cycle. This achieves fully automated integrated processing of deburring the end face and inner edge of the steel pipe and polishing the inner wall.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
