Description

Technical Field

[0001] This invention relates to the field of metal polishing technology, specifically to a device for polishing the end and outer surface of stainless steel handles. Background Technology

[0002] When polishing L-shaped stainless steel grips, existing technologies typically focus on processing the main gripping areas, such as the vertical outer surface and bottom surface. These areas are not only directly in contact with the hands, but their smoothness directly affects the user experience. Moreover, these areas often need to be assembled with additional grip shells or protective covers, so the surface quality requirements are high. Traditional polishing devices mostly use fixed clamps or polishing wheels with a single movement trajectory. For example, they use a rotating base with a nozzle for sandblasting, or use a vertically movable polishing disc to treat the surface of the fixedly clamped handle. However, such devices generally suffer from the following problems when dealing with the unique geometry of L-shaped grips: they struggle to efficiently process the end arc surface, chamfered surface, and complex transition area where the outer surface meets the end of the grip simultaneously, resulting in these areas becoming polishing dead zones and poor polishing uniformity; in addition, traditional equipment often lacks self-adaptability, failing to intelligently adjust the polishing surface or automatically adapt to grips of different sizes. When polishing L-shaped structures, the operation is cumbersome, requiring multiple clamping or manual intervention, resulting in low efficiency. Furthermore, continuous friction at a single point can easily cause overheating damage or uneven wear to the polishing surface, affecting the final product quality and production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a polishing device for the end and outer surface of stainless steel handles, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a polishing device for the end and outer surface of a stainless steel handle, comprising a support ring and an L-shaped handle. Six sliding frames are fixedly connected in an array to the inner wall of the support ring. A slider is slidably connected in the cavity of each sliding frame. A central rod is fixedly connected to the lower end of each slider. A rotating shaft is installed between the central rod and the slider. A polishing sponge is sleeved on the outer wall of each central rod. Several pins are inserted into the lower end of each polishing sponge. The lower ends of the pins at the lower end of each polishing sponge are fixedly connected to a support ring, which is sleeved on the outer wall of the central rod. A steering structure is provided at the lower end of each support ring, which can push the central rod to rotate and tilt. The outer side wall of the support ring is rotatably connected to a toothed ring. The upper surface of the toothed ring is provided with six guide grooves at equal intervals. Each guide groove is slidably connected to an L-shaped push rod. The side surface of each L-shaped push rod is fixed to the corresponding slider. At the same time, the L-shaped push rod is slidably connected to the support ring. The outer wall of the support ring is fitted with a protective shell, and the inner wall of the protective shell is provided with a rotating structure, which can rotate the polishing sponge.

[0005] The preferred steering structure includes a connecting plate, the upper end of which is fixedly connected with a plurality of inserts, each insert being inserted into a support ring. The outer side wall of the support ring is provided with a plurality of sliding cavities, and the sliding cavities are longitudinally slidably connected to the inner wall of the connecting plate.

[0006] Preferably, each of the connecting plates has a rotating plate rotatably connected to its side surface. A washer is slidably inserted between the support ring and the protective shell. A spring is fixedly connected to the upper end of the washer, and an abutment ring is fixedly connected to the upper end of the spring. The inner wall of the abutment ring is slidably connected to the rotating plate at the corresponding position. An elastic rotating rod is rotatably connected between the washer and each connecting plate. A collar is rotatably connected to the outer wall of the abutment ring. Several pressure plates are fixedly connected to the outer wall of the collar, and the pressure plates are slidably connected longitudinally to the outer wall of the protective shell.

[0007] The preferred rotating structure includes a second abutment ring, which is disposed at the upper end of the first abutment ring. The second abutment ring is fixed to the inner wall of the protective shell, and the inclined surfaces of the second abutment ring and the first abutment ring are adjacent to each other.

[0008] Preferably, a main motor is fixedly connected to the outer wall of the protective shell, a gear is fixedly connected to the output end of the main motor, and the gear meshes with a gear ring, and a guide ring is sleeved on the lower end of the protective shell.

[0009] Preferably, the outer wall of the protective shell is fixedly connected to two symmetrically positioned extension shells. A rotating shaft is rotatably connected inside the cavity of each extension shell. A limiting plate is sleeved on the outer wall of the rotating shaft, and the limiting plate abuts against the lower end of the washer. A torsion spring is sleeved on the outer wall of the rotating shaft, and the torsion spring is fixedly connected to the extension shell.

[0010] Preferably, an electric slide rod is installed on the side surface of the protective shell, and a base is fixedly connected to the lower end of the electric slide rod. Several brackets that can slide towards the center of the base are installed in a row along the center of the upper end of the base. An L-shaped pressure block is rotatably connected in the cavity of each bracket, and each L-shaped pressure block can abut against the upper surface of the pressure plate at the corresponding position.

[0011] Preferably, each of the L-shaped pressure blocks is rotatably connected to an end support plate. A second spring is fixedly connected to the lower end of the end support plate. An auxiliary motor is also fixedly connected to the lower end of the end support plate, and the output end of the auxiliary motor extends through to the upper end of the end support plate. An end polishing sponge is fixedly connected to the output end of the auxiliary motor, and the end polishing sponge can abut against the lower end of the L-shaped handle. A clamp is provided at the end of the L-shaped handle away from the end support plate, and the clamp clamps the L-shaped handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This device uses a main motor to drive a gear-meshing ring to rotate, causing a guide groove to push an L-shaped push rod, which in turn moves a slider within a sliding frame. This allows the polishing sponge on the outer side of the central rod to adapt to and polish L-shaped handles of different diameters without manual adjustment. When the support ring rotates, the inclined surfaces of the second and first contact rings collide, driving the polishing sponge to automatically change sides, reducing single-sided wear and overheating, and extending its service life. The lever action of the limiting plate within the extension housing and the rotating shaft allows for quick disassembly and replacement of the polishing sponge, reducing maintenance costs. When the electric slide rod moves the protective housing downwards, the guide ring pushes the end support plate, causing the L-shaped pressure block to press down on the pressure plate, causing the polishing sponge to tilt around the rotating shaft. This, combined with the auxiliary motor-driven end polishing sponge, eliminates the polishing blind spot at the intersection of the L-shaped handle's end face and outer surface, improving polishing integrity and quality.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-10 The present invention provides a technical solution: a polishing device for the end and outer surface of a stainless steel handle, comprising a support ring 1 and an L-shaped handle 26. Six sliding frames 2 are fixedly connected to the inner wall of the support ring 1 in an array. A slider 3 is slidably connected in the cavity of each sliding frame 2. A central rod 5 is fixedly connected to the lower end of each slider 3. A rotating shaft 6 is installed between the central rod 5 and the slider 3. A polishing sponge 7 is sleeved on the outer wall of each central rod 5. Several pins 9 are inserted into the lower end of each polishing sponge 7. The lower ends of the pins 9 at the lower end of each polishing sponge 7 are fixedly connected to a support ring 8. The support ring 8 is sleeved on the outer wall of the central rod 5. A steering structure is provided at the lower end of each support ring 8, which can push the central rod 5 to rotate and tilt. A toothed ring 21 is rotatably connected to the outer wall of the support ring 1. Six guide grooves 22 are equidistantly opened on the upper surface of the toothed ring 21. An L-shaped push rod 4 is slidably connected in the cavity of each guide groove 22. The side surface of each L-shaped push rod 4 is fixedly connected to the corresponding slider 3. At the same time, the L-shaped push rod 4 is slidably connected to the support ring 1. The outer wall of the support ring 1 is fitted with a protective shell 25, and the inner wall of the protective shell 25 is provided with a rotating structure, which can rotate the polishing sponge 7.

[0017] Specifically, by rotating the gear ring 21, the position of the guide groove 22 changes, thereby causing the L-shaped push rod 4 to move. During the movement of the L-shaped push rod 4, the corresponding slider 3 will move within the cavity of the slide frame 2. During the movement of the slider 3, the center rod 5 and the polishing sponge 7 will move together, allowing the side surface of the polishing sponge 7 to contact the L-shaped handle 26 and polish its outer surface. The steering structure can increase the resistance generated when the support ring 1 needs to rotate initially, so that when the gear ring 21 rotates, it will first drive the polishing sponge 7 to move towards the L-shaped handle 26. Then, when the polishing sponge 7 contacts the L-shaped handle 26 and can no longer move, the rotation of the L-shaped handle 26 will overcome the resistance of the steering structure, so that the gear ring 21 will start to drive the support ring 1 to rotate together. This allows the gear ring 21 to automatically adapt to the outer diameter of the L-shaped handle 26 when polishing the outer wall of the L-shaped handle 26 with different diameters. At the same time, it will drive the single surface of each polishing sponge 7 to polish the outer wall of the L-shaped handle 26.

[0018] In this embodiment, the steering structure includes a connecting plate 10, with a plurality of inserts 11 fixedly connected to the upper end of the connecting plate 10, and each insert 11 is inserted into the support ring 8. The outer side wall of the support ring 8 is provided with a plurality of sliding cavities 81, and the sliding cavities 81 are longitudinally slidably connected to the inner wall of the connecting plate 10.

[0019] In this embodiment, a rotating plate 13 is rotatably connected to the side surface of each connecting plate 10. A washer 18 is slidably inserted between the support ring 1 and the protective shell 25. A spring 17 is fixedly connected to the upper end of the washer 18. An abutment ring 14 is fixedly connected to the upper end of the spring 17. The inner wall of the abutment ring 14 is slidably connected to the rotating plate 13 at the corresponding position. An elastic rotating rod 12 is rotatably connected between the washer 18 and each connecting plate 10. A collar 16 is rotatably connected to the outer wall of the abutment ring 14. Several pressure plates 19 are fixedly connected to the outer wall of the collar 16, and the pressure plates 19 are longitudinally slidably connected to the outer wall of the protective shell 25.

[0020] In this embodiment, the rotating structure includes a second abutment ring 15, which is disposed at the upper end of the first abutment ring 14. The second abutment ring 15 is fixed to the inner wall of the protective shell 25, and the inclined surfaces of the second abutment ring 15 and the first abutment ring 14 adjacent to each other abut against each other.

[0021] In this embodiment, a main motor 24 is fixedly connected to the outer wall of the protective shell 25, a gear 23 is fixedly connected to the output end of the main motor 24, and the gear 23 meshes with the gear ring 21. A guide ring 20 is sleeved on the lower end of the protective shell 25.

[0022] Specifically, when the toothed ring 21 pushes the polishing sponge 7 to contact the outer wall of the L-shaped handle 26, the rotation of the toothed ring 21 will cause the support ring 1 to rotate along with it via the L-shaped push rod 4. During the rotation of the support ring 1, the first abutment ring 14 will also rotate. As the abutment ring 14 rotates within the inner wall of the collar 16, the upper inclined surface of the first abutment ring 14 will contact the lower inclined surface of the second abutment ring 15 every half turn. The second abutment ring 15 is fixed to the inner wall of the protective shell 25. Therefore, whenever the upper inclined surface of the first contact ring 14 abuts against the lower inclined surface of the second contact ring 15, a certain rotational resistance is generated, causing the toothed ring 21 to preferentially push the L-shaped push rod 4 to move during rotation. Then, when the inclined surfaces of the first contact ring 14 and the second contact ring 15 abut against each other, generating assistance, the two inclined surfaces abut against each other, causing the first contact ring 14 to move downward. During the downward movement of the first contact ring 14, the spring 17 is compressed, and at the same time, the position of the washer ring 18... While remaining unchanged, as spring 17 moves downward, it drives rotating plate 13, connecting plate 10, and sliding cavity 81 to move downward together. During this movement, elastic rotating rod 12 rotates synchronously and shortens. Meanwhile, sliding cavity 81 is always fitted onto the outer wall of support ring 8. However, insert block 11 disconnects from support ring 8 at this time, allowing support ring 8 to rotate around center rod 5. During the disconnection of insert block 11, support ring 1 continues to rotate. During the rotation of support ring 1, polishing sponge 7, through friction with the surface of L-shaped handle 26, begins to rotate around center rod 5, and support ring 8 rotates along with it. When contact ring 14 returns to its original position and moves upward, insert block 11 re-inserts into support ring 8. This allows polishing sponge 7 to automatically change polishing surfaces when polishing the outer wall of L-shaped handle 26, thereby reducing wear on one side and preventing heat generation on a single side due to long-term polishing.

[0023] In this embodiment, two symmetrically positioned extension shells 37 are fixedly connected to the outer wall of the protective shell 25. A rotating shaft 39 is rotatably connected inside the cavity of the extension shell 37. A limiting plate 38 is sleeved on the outer wall of the rotating shaft 39, and the limiting plate 38 abuts against the lower end of the washer 18. A torsion spring 40 is sleeved on the outer wall of the rotating shaft 39, and the torsion spring 40 is fixedly connected to the extension shell 37.

[0024] In this embodiment, an electric slide bar 28 is installed on the side surface of the protective shell 25. The lower end of the electric slide bar 28 is fixedly connected to a base 29. Several brackets 30 that can slide towards the center of the base 29 are installed in a row along the center of the upper end of the base 29. Each bracket 30 is rotatably connected to an L-shaped pressure block 31 in its cavity, and each L-shaped pressure block 31 can abut against the upper surface of the pressure plate 19 at the corresponding position.

[0025] In this embodiment, each L-shaped pressure block 31 is rotatably connected to an end support plate 32. A spring 33 is fixedly connected to the lower end of the end support plate 32. An auxiliary motor 35 is also fixedly connected to the lower end of the end support plate 32, and the output end of the auxiliary motor 35 extends through to the upper end of the end support plate 32. An end polishing sponge 34 is fixedly connected to the output end of the auxiliary motor 35, and the end polishing sponge 34 can abut against the lower end of the L-shaped handle 26. A clamp 27 is provided at the end of the L-shaped handle 26 away from the end support plate 32, and the clamp 27 clamps the L-shaped handle 26. Specifically, the worker can manually press down the end of the limiting plate 38 away from the washer ring 18, and use the lever principle of the rotating shaft 39 to make the limiting plate 38 lift the washer ring 18. At the same time, the spring 17 is compressed until the limiting plate 38 rotates into the interior of the extension shell 37. At this time, the elastic return of the spring 17 will push the washer ring 18 to move downward. At the same time, the lower end of the washer ring 18 is not restricted by the limiting plate 38. Through the inertia generated by the downward movement of the washer ring 18, the washer ring 18 can drive the spring 17, as well as the support ring 8 connected to the contact ring 14 and the polishing sponge 7, to move downward together. The polishing sponge 7 is separated from the outer wall of the center rod 5. By opening the guide ring 20, the polishing sponge 7 can be replaced. Furthermore, as the L-shaped handle 26 is polished from top to bottom, the protective shell 25 is continuously moved downwards by the electric slide rod 28, causing the polishing sponge 7 to continuously polish the surface of the L-shaped handle 26. During the polishing process of the polishing sponge 7, the auxiliary motor 35 also drives the end polishing sponge 34 to polish the lower end of the L-shaped handle 26. When the guide ring 20 moves with the protective shell 25 to contact the end support plate 32, it pushes the end support plate 32 downwards. At the same time, each bracket 30 also moves towards the protective shell 25, and the L-shaped pressure block 31 also rotates around the bracket 30, so that the L-shaped pressure block 31 abuts against the upper surface of the pressure plate 19. As the protective shell 25 descends, the polishing sponge 7 gradually detaches from the side surface of the bottom of the L-shaped handle 26. At this point, the L-shaped pressure block 31 pushes the pressure plate 19 downwards, which in turn pushes the collar 16 and the contact ring 14 downwards together. When the contact ring 14 moves beyond the longitudinal sliding range of the connecting plate 10 and the sliding cavity 81, the downward movement of the contact ring 14 pushes the rotating plate 13, the connecting plate 10, the support ring 8, and the polishing sponge 7 downwards together, causing a portion of the polishing sponge 7 to detach from the outer wall of the central rod 5. Simultaneously, the rotating shaft 6 moves to a position above the polishing sponge 7. At this point, when the elastic rotating rod 12 retracts beyond its limit, refer to... Figure 6The elastic rotating rod 12 will push the support ring 8, polishing sponge 7, and center rod 5 to rotate counterclockwise around the rotating shaft 6, causing the polishing sponge 7 to tilt. At this time, the rotation of the support ring 1 will drive the polishing sponge 7 to polish the chamfered or arc surface of the lower end of the L-shaped handle 26. Furthermore, it transitions with the end polishing sponge 34 on the lower surface of the L-shaped handle 26, reducing the problem of ineffective polishing at the intersection point when polishing both the end face and outer surface of the L-shaped handle 26 simultaneously.

[0026] Working principle: The main motor 24 drives the gear 23 to mesh with the gear ring 21 and rotate. The guide groove 22 on the gear ring 21 pushes the L-shaped push rod 4, causing the slider 3 to slide within the slide frame 2. This drives the polishing sponge 7 on the outside of the center rod 5 to move radially until it contacts the outer surface of the L-shaped handle 26. When the polishing sponge 7 contacts the handle, the rotating surface structure increases the resistance, and the torque forces the support ring 1 to rotate as a whole for polishing. This process has the characteristic of adapting to handles of different diameters. When the support ring 1 rotates, the fixed abutment ring 2 15 will periodically abut against the inclined surface of the abutment ring 1 14 connected to the support ring 1, forcing the abutment ring 1 14 to compress the spring 17 and move downward. The rotating plate 13 and the connecting plate 10 pull the support ring 8 down, causing the insert block 11 to separate from the support ring 8. At this time, the polishing sponge 7 can rotate around the central rod 5 under the friction force on the handle surface, realizing automatic replacement of the polishing surface and avoiding single-point overheating and wear. When the device is driven down by the electric slide rod 28 to polish the outer wall of the lower end of the handle, the guide ring 20 contacts the end support plate 32, pushes the L-shaped pressure block 31 to press down the pressure plate 19, and then further presses down the collar 16 and the abutment ring 14. Finally, the elastic rotating rod 12 drives the polishing sponge 7 to tilt around the rotating shaft 6, thereby connecting with the end polishing sponge 34 and completing the coordinated polishing of the outer surface and the end transition area.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
