Description

Technical Field

[0001] This utility model relates to the field of steel structure polishing devices, specifically a polishing device for steel structure surfaces. Background Technology

[0002] Steel surface polishing is a process that removes microscopic protrusions from the surface of steel by rubbing with abrasives or polishing tools, thereby improving the smoothness and precision of the surface. Application areas include manufacturing industries such as automobiles and aerospace, where it improves the surface quality and corrosion resistance of parts; medical devices such as surgical instruments and implants, which require high surface smoothness and biocompatibility; and architectural decoration, such as stainless steel decorative panels, where it enhances aesthetics and corrosion resistance.

[0003] Mechanical polishing of cylindrical steel surfaces requires the use of grinding tools to rub the steel surface. Traditional polishing devices for cylindrical steel structures often only polish one side of the steel, and usually do not process the steel from multiple sides at the same time. This makes it impossible to polish the steel thoroughly, and it can also easily change the cylindrical shape of the steel, leading to a reduction in the strength of the steel structure and the assembly accuracy. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, such as the inability to polish steel from multiple surfaces simultaneously or change its shape, which leads to insufficient polishing and reduced strength and assembly precision of the steel structure, this utility model proposes a polishing device for steel structure surfaces.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a polishing device for steel structure surface, including a base, a bracket fixedly connected to the top of the base, a clamping mechanism provided on one side of the bracket, a bottom barrel fixedly connected to one side of the base, a waste bin provided in the inner cavity of the bottom barrel, and a polishing mechanism fixedly connected to the inner wall of the bottom barrel.

[0006] The polishing mechanism includes multiple chip-proof walls. The surfaces of the chip-proof walls are slidably connected to the inner wall of the bottom barrel. A sliding table is fixedly connected to the bottom of the chip-proof wall. A polishing cylinder is rotatably connected to one side of the sliding table. A support platform is rotatably connected to the bottom of the sliding table. A transmission mechanism is provided at the bottom of the sliding table.

[0007] Preferably, the transmission mechanism includes a first motor, which is fixedly connected to the inner wall of the bottom barrel. The output end of the first motor is fixedly connected to a first rotating shaft, and a connecting plate is fixedly connected to the surface of the first rotating shaft. One end of the first rotating shaft is fixedly connected to one side of the support platform. One end of the polishing cylinder is fixedly connected to a second rotating shaft, and the surface of the second rotating shaft is rotatably connected to the inner cavity of the connecting plate. A planetary gear is fixedly connected to the surface of the second rotating shaft. A gear ring is fixedly connected to the inner wall of the bottom barrel, and the teeth of the gear ring mesh with the teeth of the planetary gear.

[0008] Preferably, a slider is fixedly connected to one side of the sliding platform, and a groove is provided on the inner wall of the bottom barrel, with the surface of the slider slidably connected to the inner cavity of the groove.

[0009] Preferably, a partition plate is rotatably connected to the surface of the first rotating shaft, one side of the partition plate abuts against one side of the connecting plate, and a baffle is fixedly connected to the top of the partition plate.

[0010] Preferably, the clamping mechanism includes a first cylinder, which is fixedly connected to the top of the bracket, and a protective shell is fixedly connected to the output end of the first cylinder. A second cylinder is fixedly connected to the inner wall of the protective shell.

[0013] The advantages of this utility model are:

[0014] This invention solves the problem that mechanical polishing of cylindrical steel materials requires friction on the surface of the steel material, which can damage the cylindrical structure and reduce the strength and assembly accuracy of the steel structure. The first motor starts working and drives the first rotating shaft to rotate. The first rotating shaft drives the connecting plate to rotate, causing the planetary gear connected to the connecting plate to rotate along the gear ring track and rotate on its own axis. The rotation of the planetary gear drives the second rotating shaft fixed on one side of the planetary gear to rotate, thereby driving the polishing cylinder to rotate. The friction between the surface of the polishing cylinder and the surface of the raw material achieves the polishing effect. This invention solves the problem that mechanical polishing of cylindrical steel materials requires friction on the surface of the steel material, which can damage the cylindrical structure and reduce the strength and assembly accuracy of the steel structure.

[0023] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a polishing apparatus for steel structure surfaces. (Refer to...) Figure 1 and Figure 2 A polishing device for steel structure surfaces includes a base 1, a bracket 2 fixedly connected to the top of the base 1, a clamping mechanism 3 provided on one side of the bracket 2, a bottom barrel 4 fixedly connected to one side of the base 1, a waste bin 5 provided in the inner cavity of the bottom barrel 4, and a polishing mechanism 6 fixedly connected to the inner wall of the bottom barrel 4.

[0026] The polishing mechanism 6 includes multiple chip-proof walls 601. The surfaces of the chip-proof walls 601 are slidably connected to the inner wall of the bottom barrel 4. A sliding table 602 is fixedly connected to the bottom of the chip-proof walls 601. A polishing cylinder 603 is rotatably connected to one side of the sliding table 602. A support table 604 is rotatably connected to the bottom of the sliding table 602. A transmission mechanism 7 is provided at the bottom of the sliding table 602. By setting up the polishing mechanism 6, the cylindrical steel material to be processed is placed into the bottom barrel 4, positioned and clamped on the support table 604, and then rotates synchronously with the support table 604. At the same time, the polishing cylinder 603, which rubs against the surface of the material, rotates. Since the surface of the polishing cylinder 603 is rough and both the polishing cylinder 603 and the material are cylindrical, the rotation of the polishing cylinder 603 can polish the surface of the material without damaging the structure of the cylindrical material, thus achieving full processing of the material.

[0027] Reference Figure 2 The transmission mechanism 7 includes a first motor 701, which is fixedly connected to the inner wall of the bottom barrel 4. A first rotating shaft 702 is fixedly connected to the output end of the first motor 701. A connecting plate 703 is fixedly connected to the surface of the first rotating shaft 702. One end of the first rotating shaft 702 is fixedly connected to one side of the support platform 604. A second rotating shaft 704 is fixedly connected to one side of the polishing cylinder 603. The surface of the second rotating shaft 704 is rotatably connected to the inner cavity of the connecting plate 703. A planetary gear 705 is fixedly connected to the surface of the second rotating shaft 704. A gear ring 706 is fixedly connected to the inner wall of the bottom barrel 4. The teeth of the gear ring 706 mesh with the teeth of the planetary gear 705. With the transmission mechanism 7 in place, the first motor 701 starts working and drives the first rotating shaft 702 at the output end to rotate, thereby driving the connecting disk 703 fixedly connected to the surface of the first rotating shaft 702 to rotate. Since the second rotating shaft 704 fixedly connected to one side of the planetary gear 705 is rotatably connected to the inner cavity of the connecting disk 703, and the teeth of the planetary gear 705 mesh with the teeth of the gear ring 706, the planetary gear 705 can revolve around and rotate along the track of the gear ring 706. Thus, the rotation of the planetary gear 705 can drive the rotation of the second rotating shaft 704, which in turn can drive the polishing cylinder 603 fixedly connected to the second rotating shaft 704 to rotate, thereby realizing the transmission of power.

[0028] Reference Figure 2A slider 8 is fixedly connected to one side of the sliding table 602. A groove 9 is provided on the inner wall of the bottom barrel 4. The surface of the slider 8 is slidably connected to the inner cavity of the groove 9. By setting the groove 9 and the slider 8, the sliding table 602 is restricted, so that the sliding table 602 can rotate around the center of the bottom barrel 4 instead of the second rotating shaft 704 rotating in the inner cavity of the sliding table 602 causing the sliding table 602 to rotate on its own.

[0029] Reference Figure 2 , Figure 3 and Figure 4 A partition plate 10 is rotatably connected to the surface of the first rotating shaft 702. One side of the partition plate 10 abuts against one side of the connecting plate 703. A baffle 11 is fixedly connected to the top of the partition plate 10. By setting the baffle 11, waste chips will inevitably be generated during the polishing process of the polishing cylinder 603. These waste chips will scatter in the bottom barrel 4. However, the waste chips will fall onto the support plate due to the restriction of the anti-chip wall 601 and gravity. As the support plate rotates, the waste chips are subjected to centrifugal force and move towards the edge of the support plate. Then, the waste chips fall down along the baffle 11 through the gap between the sliding tables 602. Since the sliding tables 602 move synchronously with the planetary gear 705, the waste chips will basically not fall onto the planetary gear 705. The waste chips finally fall into the waste bin 5, realizing the cleaning and collection of waste chips.

[0030] Reference Figure 6 The clamping mechanism 3 includes a first cylinder 301, which is fixedly connected to the top of the bracket 2. A protective shell 302 is fixedly connected to the output end of the first cylinder 301, and a second cylinder 303 is fixedly connected to the inner wall of the protective shell 302. By setting the first cylinder 301, the protective shell 302 fixedly connected to the output end of the first cylinder 301 and the second cylinder 303 inside the protective shell 302 can move vertically, thereby realizing the vertical movement of the clamping device after clamping the raw material.

[0031] Reference Figure 6 The output end of the second cylinder 303 is fixedly connected to a movable ring 304, and a fixed ring 305 is fixedly connected to one side of the protective shell 302. A clamping claw 306 is rotatably connected to the surface of the fixed ring 305, and the surface of the movable ring 304 is rotatably connected to the inner wall of the clamping claw 306. By setting the clamping claw 306, when the second cylinder 303 starts working, it drives the movable ring 304, which is fixedly connected to the output end of the second cylinder 303, to move vertically. Since the fixed ring 305 is fixedly connected to the protective shell 302, and the clamping claw 306 is rotatably connected with the fixed ring 305 and the movable ring 304 as fulcrums respectively, when the second cylinder 303 extends, the movable ring 304 descends vertically, and the clamping end of the clamping claw 306 retracts inward, thereby clamping the raw material.

[0032] Reference Figure 5A collection plate 12 is rotatably connected to the inner wall of the bottom drum 4. A roller 13 is slidably connected to one side of the collection plate 12. The surface of the roller 13 is rotatably connected to the inner wall of the bottom drum 4. By setting the collection plate 12, the waste debris falling into the waste bin 5 can be carried. Since the door of the waste bin 5 only opens to one side, by setting the roller 13, the roller 13 can drive the collection plate 12 to rotate around the center of the bottom drum 4, so that the waste debris accumulated on the collection plate 12 can be rotated to the door for processing.

[0033] Working principle: The second cylinder 303 starts working, driving the movable ring 304, which is fixedly connected to the output end of the second cylinder 303, to move vertically. Since the fixed ring 305 is fixedly connected to the protective shell 302, and the clamping claw 306 is rotatably connected with the fixed ring 305 and the movable ring 304 as fulcrums respectively, when the second cylinder 303 extends, the movable ring 304 descends vertically, and the clamping end of the clamping claw 306 retracts inward, causing the material to be clamped by the clamping mechanism 3. Then, the first cylinder 301 starts working and extends, driving the clamping claw 306 and the clamped material to move vertically until they contact the support plate. The first motor 701 starts working, driving the first rotating shaft 702 to rotate, thereby driving the connecting disk 703, which is fixedly connected to the surface of the first rotating shaft 702, to rotate. Since the second rotating shaft 704, fixedly connected to one side of the planetary gear 705, is rotatably connected to the inner cavity of the connecting disk 703, and the teeth of the planetary gear 705 mesh with the teeth of the gear ring 706, ... The planetary gear 705 can revolve and rotate along the track of the gear ring 706. The rotation of the planetary gear 705 can drive the rotation of the second rotating shaft 704, which in turn can drive the polishing cylinder 603 fixedly connected to the second rotating shaft 704 to rotate. Since the surface of the polishing cylinder 603 is rough and both the polishing cylinder 603 and the raw material are cylindrical, the rotation of the polishing cylinder 603 can polish the surface of the raw material without damaging the structure of the cylindrical raw material. The waste chips generated during the polishing process will fall onto the support plate due to the restriction of the chip-proof wall 601 and gravity. As the support plate is driven to rotate by the first rotating shaft 702, the waste chips are moved towards the edge of the support plate by centrifugal force. Then, the waste chips fall down along the baffle 11 through the gap between the sliding tables 602 to the surface of the collection plate 12 of the waste bin 5, realizing the cleaning and collection of waste chips. Finally, the clamping claw 306 retracts, so that the polished raw material held in the clamp is removed from the bottom barrel 4, completing the processing process.

[0034] 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.
