Description

Technical Field

[0001] This utility model relates to the technical field of floor processing, specifically to a floor surface polishing device. Background Technology

[0002] In flooring production, sanding is one of the core processes. Floor sanding removes surface imperfections and smooths out raised areas, improving the flatness and durability of the floor, thereby enhancing its practicality and lifespan.

[0003] In practical applications, existing floor surface polishing devices have relatively complete structures and functions, and can basically meet daily usage needs. However, the following problems still exist: In actual use, when the floor surface sanding device clamps and positions the floor, the floor needs to be centered and aligned before the clamp is used to fix the floor. The clamp cannot center the floor on its own, so sanding is quite troublesome. In addition, the clamp will interfere with the sanding of the floor edges. After the two edges of the floor are sanded, the clamp needs to be released, the floor needs to be rotated and then clamped again, and then the unsanded edges of the floor need to be sanded, which is quite troublesome.

[0004] Therefore, this utility model provides a floor surface polishing device. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a floor surface polishing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a floor surface grinding device, comprising a base plate and an angle grinder; The angle grinder is mounted on top of the base plate; An operating table is fixedly connected to the top of the base plate, and a centering positioning structure is provided on the top of the operating table. The central positioning structure includes four slide rails located at the bottom of the operating table. Two slide rails are arranged in a group, and two groups of slide rails are symmetrically arranged at the bottom of the operating table. Each group of slide rails has a slider slidably connected to it. Two sliders are arranged in a group, and each group of sliders is fixedly connected to a sliding platform. A sliding rod is fixedly connected inside each of the two sliding platforms. A bidirectional lead screw is rotatably connected inside each of the two sliding platforms. Two sliders are slidably connected to each of the two sliding rods, and each slider is threadedly connected to the bidirectional lead screw. A sliding seat is fixedly connected to the top of each slider. A rotating seat is rotatably connected to the top of each sliding seat. Two positioning rods are fixedly connected to each of the four positioning rods at the end furthest from the rotating seat. A rotating mechanism is located in the center of the operating table, and a torsion spring is provided between the top of the sliding seat and the rotating seat.

[0007] The technical effect of adopting the above-mentioned further solution is that the second slider can synchronously approach or move away from the middle of the bidirectional lead screw under the action of the bidirectional lead screw, and the second slider can be flexibly adjusted according to the different widths of the base plate. When the sliding seat approaches the floor, the edge of the floor will push the roller to make the rotating seat rotate, and drive the floor to rotate until another roller on it contacts the edge of the floor. At this time, the four sets of eight rollers respectively position the four corners of the floor, thereby achieving the effect of centering the floor. When the floor vibrates under the action of the angle grinder, the vibration will cause the floor to slide slightly on the top of the rotating table, so that the floor will squeeze the roller on the side of the sliding direction. Then the roller drives the rotating seat to rotate through the positioning rod. When the rotating seat rotates, the torsion spring deforms. Then the torsion spring drives the rotating seat to reset under the action of elasticity, so that the rotating seat pushes the roller back through the positioning rod, thereby buffering the floor and keeping the floor centered during the grinding process.

[0008] In a preferred embodiment, a motor is fixedly installed on one side of each of the two sliding tables, and both motors are coaxially and fixedly connected to a bidirectional lead screw. An electric telescopic rod is fixedly installed at the bottom of the operating platform, and the movable end of the electric telescopic rod is fixedly connected to one of the sliding tables. A rotating plate is rotatably connected to the bottom of the operating platform, and connecting rods are rotatably connected to both ends of the rotating plate. The ends of the two connecting rods furthest from the rotating plate are rotatably connected to the sliding tables, and the two connecting rods are centrally symmetrical about the rotating plate.

[0009] The technical effect of adopting the above-mentioned further solution is that when a sliding table moves towards the center of the operating table, the sliding table pushes the rotating plate to rotate through the connecting rod, thereby causing another connecting rod on the rotating plate to pull the sliding table to slide synchronously towards the center of the operating table, thereby clamping and centering the floor.

[0010] In a preferred embodiment, the rotating mechanism includes a rotating platform rotatably connected to the top of the operating table. An electric telescopic rod two is fixedly installed on the bottom of the operating table away from the electric telescopic rod one. A rack is fixedly connected to the movable shaft of the electric telescopic rod two, and a gear is fixedly connected to the side of the electric telescopic rod two. The rack and gear are meshed together.

[0011] The technical effect of adopting the above-mentioned further solution is as follows: Activating the electric telescopic rod two causes its movable end to retract, thereby causing it to slide in the direction of approach. At this time, it rotates under the meshing action. After driving the floor at its top to rotate 90 degrees, the movable end stops retracting, so that the four rollers first contact the edge of the floor. At this time, the workers can polish the previously unpolished edge of the floor.

[0012] In one preferred embodiment, a controller is included, which is electrically connected to a motor, an electric telescopic pole one, and an electric telescopic pole two.

[0013] The technical effect of adopting the above-mentioned further solution is that the controller can control the opening and closing of the motor, electric telescopic pole one, and electric telescopic pole two.

[0014] This utility model provides a floor surface polishing device. It has the following beneficial effects: By setting a centering positioning structure, slider two, driven by a bidirectional lead screw, can synchronously approach or move away from the center of the bidirectional lead screw, thereby achieving flexible movement of slider two. This allows slider two to dynamically adjust according to the difference in the width of the base plate to adapt to the sanding needs of different sized floorboards. When the sliding seat approaches the floorboard, the edge of the floorboard will push the roller, which in turn drives the rotating seat to rotate, causing the floorboard to rotate until the other roller contacts the edge of the floorboard. At this time, the four sets of eight rollers respectively position the four corners of the floorboard, thereby achieving precise centering positioning of the floorboard. Under the vibration of the angle grinder during sanding, the floorboard will slightly slide on the top of the rotating table, causing the floorboard to press against the roller on the side of the sliding direction. The roller drives the rotating seat to rotate through the positioning rod. When the rotating seat rotates, the torsion spring deforms, and then the torsion spring returns to its original position under the action of elasticity, driving the rotating seat to push the roller back through the positioning rod, thereby buffering the floorboard during the sanding process and maintaining its centered state.

[0017] 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 protection scope of the present utility model.

[0018] like Figures 1-5As shown, this embodiment provides a technical solution: a floor surface grinding device, including a base plate 1 and an angle grinder 2. The angle grinder 2 is disposed on the top of the base plate 1, and an operating table 3 is fixedly connected to the top of the base plate 1. A centering positioning structure 4 is disposed on the top of the operating table 3. The centering positioning structure 4 includes four slide rails 41 disposed on the bottom of the operating table 3. The slide rails 41 are arranged in pairs, and the two sets of slide rails 41 are symmetrically disposed on the bottom of the operating table 3. A slider 42 is slidably connected to each set of slide rails 41. Two sliders 42 are arranged in pairs, and each set of sliders 42 is fixedly connected to a sliding table 43. By setting the slide rails 41, the sliding table 43 can slide along the slide rails 41 under the action of the sliders 42, so that the sliding table 43 can adapt to different widths. The floor has two sliding platforms 43, each with a fixed sliding rod 44. Each sliding platform 43 is rotatably connected to a bidirectional lead screw 45. Two sliders 46 are slidably connected to each sliding rod 44, and both sliders 46 are threadedly connected to the bidirectional lead screw 45. By using the bidirectional lead screw 45, the sliders 46 can synchronously move closer to or further away from the center of the bidirectional lead screw 45 under its action, allowing for flexible adjustment based on the floor width. Each slider 46 has a fixed sliding seat 47 at its top, and a rotating seat 48 is rotatably connected to the top of each sliding seat 47. Each rotating seat 48 has two fixed positioning rods 49. The ends of the four positioning rods 49 furthest from the rotating seat 48 rotate... The sliding seat 47 is connected to rollers 410. By setting two rollers 410, when the sliding seat 47 approaches the floor, the edge of the floor pushes the rollers 410, causing the rotating seat 48 to rotate and the floor to rotate until another roller 410 on the rotating seat 48 contacts the edge of the floor. At this point, the four sets of eight rollers 410 respectively position the four corners of the floor, thus achieving a centered positioning effect. A rotating mechanism 5 is set in the middle of the operating table 3. A torsion spring 411 is set between the top of the sliding seat 47 and the rotating seat 48. By setting the torsion spring 411, when the rollers 410 lose external pressure, the torsion spring 411 will drive the rotating seat 48 to reset under the action of elasticity. Motors 412 are fixedly installed on one side of each of the two sliding tables 43. Both motors 412... A motorized telescopic rod 413 is fixedly installed at the bottom of the operating platform 3, coaxially connected to the bidirectional lead screw 45. The movable end of the motorized telescopic rod 413 is fixedly connected to a sliding table 43. When the movable end of the motorized telescopic rod 413 retracts, it will drive the sliding table 43 fixedly connected to it to move towards the center of the operating platform 3. A rotating plate 414 is rotatably connected to the bottom of the operating platform 3. Both ends of the rotating plate 414 are rotatably connected to connecting rods 415. The ends of the two connecting rods 415 away from the rotating plate 414 are rotatably connected to the sliding table 43. The two connecting rods 415 are centrally symmetrical about the rotating plate 414. By setting the rotating plate 414, when one of the sliding tables 43 moves towards the center of the operating platform 3,The sliding table 43 pushes the rotating plate 414 to rotate via the connecting rod 415, thereby causing another connecting rod 415 on the rotating plate 414 to pull the sliding table 43 to slide synchronously towards the center of the operating table 3.

[0019] Going further, such as Figures 2-4 As shown: The rotating mechanism 5 includes a rotating platform 51 rotatably connected to the top of the operating table 3. An electric telescopic rod 52 is fixedly installed on the bottom of the operating table 3 away from the side of the electric telescopic rod 413. A rack 53 is fixedly connected to the movable shaft of the electric telescopic rod 52. A gear 54 is fixedly connected to the side of the electric telescopic rod 52. The rack 53 and the gear 54 are meshed. By setting the rack 53, when the movable end of the electric telescopic rod 52 retracts, it drives the rack 53 to mesh with the gear 54, thereby driving the rotating platform 51 to rotate. The mechanism includes a controller, which is electrically connected to the motor 412, the electric telescopic rod 413, and the electric telescopic rod 52. By setting the controller, the opening and closing of the motor 412, the electric telescopic rod 413, and the electric telescopic rod 52 can be controlled.

[0020] The above solutions also have the problem of vibration occurring at the top of the turntable 51 during floor sanding, such as... Figure 4 as well as Figure 5 As shown: When the worker uses the angle grinder 2 to grind the floor on top of the rotating table 51, the floor vibrates under the action of the angle grinder 2. The vibration causes the floor to slide slightly on the top of the rotating table 51, which in turn presses the roller 410 on the side of the sliding direction. The roller 410 then drives the rotating seat 48 to rotate through the positioning rod 49. When the rotating seat 48 rotates, the torsion spring 411 deforms. Then, under the action of the elastic force, the torsion spring 411 drives the rotating seat 48 to return to its original position, so that the rotating seat 48 pushes the roller 410 back through the positioning rod 49. This buffers the floor and keeps the floor centered during the grinding process.

[0021] The above solutions also have the problem of making it difficult to sand the edges of the floor, such as... Figures 1-5 As shown, after the floor is placed on the rotating table 51, the electric telescopic rod 413 is activated and its movable end is retracted, causing the two sliding tables 43 to slide synchronously toward the center of the operating table 3. This drives the slider 46, sliding seat 47, rotating seat 48, positioning rod 49, and roller 410 to approach the edge of the floor. When the floor just contacts the roller 410, the electric telescopic rod 413 stops retracting its movable end. At this time, the rotating seat 48 does not rotate under the action of the floor pressing the roller 410. Therefore, each rotating seat 48 has a roller 410 that is a certain distance away from the edge of the floor. At this time, the worker can grind the edge of the floor.

[0022] Working principle: like Figure 1-5 As shown: In use: Place the floor on top of the rotating platform 51, then start the two motors 412, so that the two motors 412 drive the bidirectional lead screw 45 to rotate synchronously, thereby driving the two sliders 46 to slide towards the middle of the bidirectional lead screw 45 under the limiting action of the sliding rod 44, until the center of the two rotating seats 48 is roughly aligned with the edge of the floor. At this time, the electric telescopic rod 413 is activated. When the movable end of the electric telescopic rod 413 retracts, it will drive the sliding platform 43, which is fixedly connected to it, to move towards the center of the operating platform 3. When the sliding platform 43 moves towards the center of the operating platform 3, it pushes the rotating plate 414 to rotate through the connecting rod 415. This causes another connecting rod 415 on the rotating plate 414 to pull the sliding platform 43 to slide towards the center of the operating platform 3 simultaneously, so that the four rollers 410 first contact the edge of the floor. At this time, each rotating seat 48 has a roller 410 that is a certain distance away from the edge of the floor. At this time, the staff... The edges of the floor can be sanded. As the electric telescopic rod 413 continues to retract, the sliding table 43 gets closer to the floor. The edge of the floor pushes the roller 410 to rotate the rotating seat 48, which in turn rotates the floor until another roller 410 on the rotating seat 48 contacts the edge of the floor. At this time, the four sets of eight rollers 410 are positioned at the four corners of the floor, thus achieving the effect of centering the floor and making it easier for workers to sand the top of the floor. Then the movable end of the electric telescopic rod 413 extends, allowing the two sliding tables 43 to return to the edge of the operating table 3. At this point, the electric telescopic rod 52 is activated, causing its movable end to retract. This, in turn, causes the rack 53 to slide closer to the rotating platform 51. Meanwhile, the gear 54 rotates under the meshing action of the rack 53. Once the rotating platform 51 has rotated the floor at its top by ninety degrees, the movable end of the electric telescopic rod 52 stops retracting. Then, the two motors 412 are activated again, causing them to synchronously drive the bidirectional lead screw 45 to rotate. Under the limiting action of the sliding rod 44, this drives the two sliders 46 to slide towards the middle of the bidirectional lead screw 45 until... The center of the rotating seat 48 is roughly aligned with the edge of the floor. At this time, the movable end of the electric telescopic rod 413 retracts, driving the sliding table 43, which is fixedly connected to it, to move towards the center of the operating table 3. When the sliding table 43 moves towards the center of the operating table 3, the sliding table 43 pushes the rotating plate 414 to rotate through the connecting rod 415, thereby causing another connecting rod 415 on the rotating plate 414 to pull the sliding table 43 to slide towards the center of the operating table 3 in sync, so that the four rollers 410 first contact the edge of the floor. At this time, the staff can polish the previously unpolished edge of the floor.
