Description

Technical Field

[0001] This utility model belongs to the technical field of polishing devices, specifically relating to a surface polishing device for hardware products. Background Technology

[0002] Hardware products refer to various parts or tools made from metal materials such as iron, copper, aluminum, and stainless steel as the main raw materials, and processed through processes such as forging, stamping, cutting, welding, and surface treatment. They are widely used in construction, machinery, electronics, home furnishing and other fields.

[0003] Polishing is a process that uses mechanical, chemical, or electrochemical methods to refine the surface of an object. Its core purpose is to reduce surface roughness and improve smoothness and aesthetics.

[0004] After the hardware products are processed, they usually need to be processed by the interaction of abrasives, polishing tools or chemical media with the surface of the workpiece to remove microscopic protrusions or defects and make the surface smooth and bright.

[0005] Currently, polishing devices for large sheet metal parts generally suffer from a single polishing angle, typically only able to grind and polish the upper surface of the workpiece. If the other side needs to be processed, the workpiece must be manually flipped, which not only increases the difficulty of operation but also affects polishing efficiency. To address this issue, we propose a surface polishing device for hardware products to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a surface polishing device for hardware products to solve the problems existing in the background art.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0020] Furthermore, the mounting bracket is provided with a protective cover on its outer side, and the transmission belt and the two transmission wheels are both located inside the protective cover.

[0021] Further specifying, the pushing component includes two sets of transmission components, two pushing plates, a push rod, a push handle, and a clamping plate;

[0022] The two sets of transmission components are symmetrically arranged on both sides of the platform, and each set of transmission components includes:

[0023] The gear has symmetrical mounting slots inside the mounting frame and is located above the platform. The gear is rotatably mounted inside the mounting slot.

[0024] Two push rods are slidably disposed inside the mounting groove and are rotationally symmetrical about the gear as the center.

[0025] A plurality of locking teeth, each of the locking teeth being fixedly connected to the side of the two push rods near the gear and meshing with the gear;

[0026] The two push plates are respectively fixedly connected to the two push rods on the same side of the two sets. The middle part of the end of any push plate away from the mounting frame is fixedly connected to the push rod. The end of the push rod that passes through the platform is fixedly connected to the push handle. The end of the other push plate facing the mounting frame is fixedly connected to the clamping plate.

[0027] Further, the platform is provided with a groove, the lower side of the clamp is located inside the groove, and the inner wall of the clamp is provided with a rubber strip.

[0028] Further specified, the platform is provided with a reinforcing plate, and the four corners of the reinforcing plate are fixed with supporting feet.

[0029] Further, the reinforcing plate is symmetrically fixed with baffles on its underside, and the two baffles are located on both sides of the polishing wheel on the lower side. The mounting frame has a placement groove on its lower wall and a sliding groove communicating with the placement groove. A storage box is placed inside the placement groove, and a handle is provided at one end of the storage box that extends out of the sliding groove.

[0030] The beneficial effects of this utility model are:

[0047] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] like Figures 1-7 As shown, a surface polishing device for hardware products includes:

[0049] Mounting bracket 100, the mounting bracket 100 is set in a square shape;

[0050] The platform 101 is installed inside the mounting frame 100. A through slot 102 is provided in the middle of the platform 101, and the through slot 102 is located in the middle of the mounting frame 100.

[0051] Two rotating shafts 103 are rotatably connected to the inner wall of the mounting bracket 100;

[0052] Two polishing wheels 104 are respectively wrapped around the outside of two rotating shafts 103;

[0053] A power assembly is installed on one side of the mounting bracket 100 and is used to drive the rotating shaft 103 to rotate.

[0054] A push component is mounted on the mounting frame 100 and located above the platform 101, and is used to push the product to move on the platform 101.

[0055] Mounting bracket 100 serves as the basic framework of the entire device, providing mounting support for other components. Its U-shaped structure creates a stable spatial layout, facilitating the arrangement of polishing-related components inside and on both sides.

[0056] The bottom of the mounting bracket 100 can be placed directly on the ground, providing a supporting foundation for the entire device.

[0057] The stage 101 is used to place the hardware products to be polished, providing a flat surface for the products so that they can maintain a relatively stable posture during the polishing process.

[0058] The through groove 102 provides a channel for polishing hardware products;

[0059] The through groove 102 is located in the middle of the stage 101 and is on the same vertical plane as the two polishing wheels 104. When the product is pushed through the through groove 102, its upper and lower surfaces will be exposed within the working range of the two polishing wheels 104, so that the two polishing wheels 104 can process both sides of the product at the same time.

[0060] The rotating shaft 103, as the mounting carrier of the polishing wheel 104, can not only transmit the driving force of the power component, but also drive the polishing wheel 104 to rotate.

[0061] Polishing wheel 104 comes into direct contact with the surface of hardware products. Through rotational motion, it grinds and polishes the product surface, removes surface imperfections, and improves the smoothness.

[0062] Two polishing wheels 104 are located on the upper and lower sides of the stage 101, respectively, and are on the same vertical plane as the through groove 102. When the rotating shaft 103 drives the polishing wheel 104 to rotate, the high-speed rotating polishing wheel 104 rubs against the product surface passing through it, thereby achieving polishing treatment on both sides of the product.

[0063] The uppermost end of the polishing wheel 104 on the lower side is on the same horizontal plane as the surface of the stage 101. This can prevent the end of the product that passes through the polishing wheel 104 from tilting, thus affecting the polishing of the product.

[0064] The power unit provides power for the rotation of the shaft 103 and the polishing wheel 104, and is the power source for the entire device.

[0065] The power components include:

[0066] Mounting box 200 is mounted on one side of mounting bracket 100;

[0067] Servo motor 201 is installed inside the mounting box 200, and the output shaft of servo motor 201 is fixedly connected to the rotating shaft 103 that passes through the mounting box 200.

[0068] Two drive wheels 202 are fixedly connected to the ends of two rotating shafts 103 that are away from the servo motor 201, respectively.

[0069] The transmission belt 203 is wrapped around the outside of the two transmission pulleys 202 in a closed loop structure.

[0070] The mounting box 200 provides installation space and protection for the servo motor 201, while isolating the servo motor 201 from the external environment, reducing the impact of external factors such as dust and polishing debris on the servo motor 201, and also avoiding the risk of direct contact between the servo motor 201 and the operator when it is running.

[0071] The mounting box 200 is fixed to one side of the mounting bracket 100, and its interior forms a closed or semi-closed cavity structure. The servo motor 201 is installed in the cavity, and the structural strength of the box stably supports the servo motor 201, ensuring that the servo motor 201 will not shift due to vibration during operation.

[0072] The servo motor 201, as a power source, provides driving force for the rotation of the shaft 103. It can precisely control the speed to ensure the stable rotation speed of the polishing wheel 104, thereby improving the consistency of polishing quality.

[0073] The transmission wheel 202 transmits power, enabling the two rotating shafts 103 to rotate synchronously, ensuring that the rotation direction and speed of the two polishing wheels 104 are consistent, and ensuring that the polishing effect on both sides of the product is uniform.

[0074] The transmission belt 203 connects the two transmission wheels 202 to realize the transmission of power, so that the two rotating shafts 103 can rotate simultaneously under the drive of the servo motor 201, ensuring the coordinated work of the two polishing wheels 104.

[0075] The mounting bracket 100 is provided with a protective cover 204 on the outside, and the transmission belt 203 and the two transmission wheels 202 are located inside the protective cover 204.

[0076] The protective cover 204 isolates and protects the transmission belt 203 and the two transmission pulleys 202. On the one hand, it prevents external objects such as the operator's hands and tools from accidentally coming into contact with the high-speed rotating transmission belt 203 and transmission pulleys 202, thus avoiding safety accidents. On the other hand, it reduces the entry of debris and dust generated during the polishing process into the working area of ​​the transmission belt 203 and transmission pulleys 202, thereby reducing the probability of them malfunctioning due to impurities getting stuck or wear.

[0077] The pushing assembly includes two sets of transmission components, two pushing plates 300, a push rod 301, a push handle 302, and a clamping plate 303;

[0078] Two sets of transmission components are symmetrically arranged on both sides of the stage 101. Each set of transmission components includes:

[0079] The gear 304 has symmetrically provided mounting slots 305 inside the mounting bracket 100, and is located above the platform 101. The gear 304 is rotatably disposed inside the mounting slots 305.

[0080] Two push rods 306 are slidably disposed inside the mounting groove 305 and are rotationally symmetrical about the gear 304 as the center.

[0081] Several locking teeth 307 are fixedly connected to the side of two push rods 306 near the gear 304 and mesh with the gear 304.

[0082] Two push plates 300 are fixedly connected to two push rods 306 on the same side of the two sets, respectively. The middle part of the end of one push plate 300 away from the mounting frame 100 is fixedly connected to the push rod 301. The end of the push rod 301 that passes through the platform 101 is fixedly connected to the push handle 302. The end of the other push plate 300 facing the mounting frame 100 is fixedly connected to the clamping plate 303.

[0083] The push plate 300 directly contacts the hardware product and pushes or clamps the product by moving synchronously on both sides, thereby ensuring the stability of the product during the polishing process.

[0084] The push rod 301 transmits the operator's pushing force, driving the connected push rod 306 and push plate 300 to move; it is the medium for force transmission.

[0085] The push handle 302 provides the operator with a point of force to push the push rod 301 and subsequent components, thereby improving the ease of operation.

[0086] The clamp 303 is fixed to the end of the push plate 300 facing the mounting bracket 100 away from the push rod 301, and cooperates with the other push plate 300.

[0087] The clamping plate 303 has a small opening and faces the polishing wheel 104, which can clamp and fix the polished product, making it convenient to pick up the product later.

[0088] When the staff pushes the push handle 302, push rod 301 and push plate 300, the product enters the polishing area of ​​the polishing wheel 104. After the product is polished, another push plate 300 will pick up the product with the clamping plate 303, so that the product can pass smoothly through the polishing area.

[0089] Gear 304, as the core of the transmission, realizes the reverse linkage of the two sets of push rods 306, ensuring that the push rods 306 on both sides move closer or further away at the same time, driving the push plate 300 to move in coordination.

[0090] The mounting slot 305 provides installation space for the transmission component. It has a limiting strip inside to restrict the push rod 306 and prevent the push rod 306 from deforming, which would affect the movement of the push rod 306 and thus affect the pushing of the product.

[0091] The push rod 306 transmits power and drives the push plate 300 to move, thereby clamping or pushing the hardware products.

[0092] The locking tooth 307 is fixed on the push rod 306 and meshes with the gear 304 to transmit force and ensure stable meshing transmission between the push rod 306 and the gear 304.

[0093] The stage 101 has a groove 308, the lower side of the clamping plate 303 is located inside the groove 308, and the inner wall of the clamping plate 303 is provided with a rubber strip 309.

[0094] The groove 308 provides movement space and limiting guidance for the clamping plate 303, ensuring that the clamping plate 303 will not rub against the surface of the stage 101 when clamping or moving with the push plate 300. At the same time, it can also allow the product to enter the interior of the clamping plate 303, thereby realizing the receiving of the push plate 300.

[0095] Rubber strip 309 increases the friction between the inner wall of clamping plate 303 and the hardware product, improves the clamping firmness, and allows the product to be smoothly removed.

[0096] The stage 101 is provided with a reinforcing plate 400, and each of the four corners of the reinforcing plate 400 is fixed with a support foot 401.

[0097] The stage 101 is provided with a reinforcing plate 400, and each of the four corners of the reinforcing plate 400 is fixed with a support foot 401.

[0098] The reinforcing plate 400 enhances the structural strength and stability of the platform 101, preventing the platform 101 from deforming or shaking due to force during the placement of hardware products or polishing, and ensuring that the platform 101 can stably support the product to be polished.

[0099] The reinforcing plate 400 is installed below the stage 101. Through its connection with the stage 101, such as a fixed connection, it uses its own rigid structure to distribute the pressure borne by the stage 101, and evenly transmits the weight of the product and the force generated during polishing, thereby improving the load-bearing capacity and deformation resistance of the stage 101.

[0100] Support foot 401 provides support for the entire device, ensuring its stability when placed.

[0101] Among them, the support feet 401 are fixed at the four corners of the reinforcing plate 400. The height of the support feet 401 supports the reinforcing plate 400 and the platform 101 above it. The structure of the four corners makes the center of gravity of the device fall stably within the support range, preventing the device from tilting or sliding during operation.

[0102] A baffle 402 is symmetrically fixed under the reinforcing plate 400, and the two baffles 402 are located on both sides of the polishing wheel 104 on the lower side. A placement groove 403 is provided on the lower wall of the mounting bracket 100. A sliding groove communicating with the placement groove 403 is provided on the mounting bracket 100. A storage box 404 is placed inside the placement groove 403. A handle 405 is provided at one end of the storage box 404 that extends out of the sliding groove.

[0103] The baffle 402 protects and limits the polishing wheel 104 on the lower side, preventing the debris generated during polishing from splashing to both sides, reducing the pollution of the surrounding environment by the debris, and preventing operators from accidentally coming into contact with the high-speed rotating lower polishing wheel 104, thus improving operational safety.

[0104] The placement slot 403 provides installation space for the storage box 404 and limits the placement position of the storage box 404. After being blocked and intercepted by the baffle 402, it can ensure that the storage box 404 can accurately connect with the debris generated during the polishing process, making it easy to collect.

[0105] The slide provides a channel for the storage box 404 to be pulled out, allowing the storage box 404 to move in and out of the placement slot 403 along the slide, making it convenient for staff to take out the storage box 404 for cleaning.

[0106] The 404 stainless steel storage box directly collects the debris generated during the polishing process (such as metal powder, abrasive residue, etc.), preventing the debris from falling to the bottom of the device or the ground, and facilitating subsequent centralized processing.

[0107] The handle 405 provides a leverage point for staff to pull out the storage box 404, making the removal and placement of the storage box 404 more convenient and effortless.

[0108] The slide is connected to the placement slot 403, and its extension direction is consistent with the pull-out direction of the storage box 404. When the staff pulls the handle 405, the storage box 404 can move smoothly along the track of the slide, realizing the operation of taking it out or putting it in the placement slot 403.

[0109] When polishing hardware products:

[0110] The servo motor 201 in the power assembly is started. The output shaft of the servo motor 201 drives the rotating shaft 103 connected to it to rotate. Through the cooperation of the transmission wheel 202 and the transmission belt 203, the other rotating shaft 103 is rotated synchronously, thereby driving the two polishing wheels 104 to rotate at high speed.

[0111] At the same time, the staff placed the hardware products on one side of the platform 101 with the push rod 301. The staff pushed the push handle 302 to move the push rod 301, the push plate 300 and the product closer to the polishing wheel 104. When the product entered the polishing range of the polishing wheel 104, the product could be polished.

[0112] Since the two polishing wheels 104 are located on the upper and lower sides of the platform and are on the same vertical plane as the through groove 102, the high-speed rotating polishing wheel 104 above will contact the upper surface of the product, while the high-speed rotating polishing wheel 104 below will pass through the through groove 102 and contact the lower surface of the product. In this way, when the product passes between the two polishing wheels 104, both sides of the product can be polished simultaneously.

[0113] The lower polishing wheel 104 is made of hard material. While polishing the lower surface of the product, it can effectively support the product passing through the through groove 102 by its own rigidity. This support can prevent the product from sagging or deviating due to gravity or uneven force during the process of pushing. It ensures that the product can move stably along the platform 101 and smoothly pass from one end to the other end through the through groove 102. This ensures that the product is within the effective range of the two polishing wheels 104 throughout the entire process after entering the mounting frame 100, thus ensuring the continuity and integrity of the polishing process.

[0114] The upper polishing wheel 104 is made of a soft material, which ensures that the product can pass between the two polishing wheels 104.

[0115] When pushing the product close to the polishing wheel 104, the operator pushes the push rod 301 through the push handle 302, causing the push rod 306 on one side to slide. The gear 304 rotates under the action of the clamping tooth 307, driving the push rod 306 on the other side to move in the opposite direction and synchronously, so that the push plates 300 on both sides (including the clamping plate 303) move closer or further away at the same time.

[0116] When the two push plates 300 are close together, one push plate 300 can push the product to move, while the clamping plate 303 on the other push plate 300 will clamp and fix the product, so that the product can pass smoothly through the polishing wheel 104 and complete the polishing process.

[0117] When the two push plates 300 move away from each other, the clamping plate 303 on the other push plate 300 can indirectly move the product away from the polishing wheel 104 when the push plate 300 moves, so that the product can pass smoothly through the polishing area.

[0118] After the product has completely passed through the two polishing wheels 104, turn off the servo motor 201 to stop the polishing wheels 104 from rotating, remove the polished product from the stage 101, check the polishing quality, and if the expected effect is not achieved, repeat the above polishing steps.

[0119] When it is necessary to clean the inside of the storage box 404, use the handle 405 to pull the storage box 404 out of the placement slot 403 along the slide, pour out the polishing debris collected inside the storage box 404, clean it, put the storage box 404 back in its original position, perform a simple cleaning of the device surface to ensure that there is no obvious debris residue on each part, and prepare for the next use.

[0120] In this embodiment, the polishing wheel is rotated at high speed by starting the servo motor. When the worker places the product on the platform, the pusher and the product are pushed together towards the polishing wheel by the pusher handle and pusher rod. After the product passes through the two polishing wheels, the two sides of the product can be polished simultaneously. When the product is pushed close to the polishing wheel, the clamping plate will also move close to the polishing wheel to provide a receiving operation for the polished product, thereby improving the product polishing efficiency.

[0121] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
