Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a cloth wheel polishing device. Background Technology

[0002] Cloth wheel polishing equipment, a type of mechanical device that uses a cloth wheel as the core abrasive tool to polish, deburr, and finish workpiece surfaces through high-speed rotation, has been widely used in many industries such as metals, jewelry, ceramics, and furniture. Its technological development stems from the increasingly stringent requirements of modern manufacturing for product surface finish, processing precision, and appearance consistency. In traditional production models, manual polishing methods suffer from low efficiency and inconsistent processing quality, making them unsuitable for the demands of industrialized mass production. This has driven the research and application of mechanized and automated polishing equipment.

[0003] With advancements in materials science, the materials used for cloth wheels have become increasingly diverse, including cotton, fleece, and non-woven fabrics. Combined with different structural designs, hardness levels, and bonding agents, these materials can meet the needs of various processes, from rough grinding to fine polishing. In terms of mechanical structure, the equipment typically employs a motor drive, coupled with belt, gear, or direct drive to achieve high-speed rotation of the cloth wheels. Its core technologies involve motor speed control, spindle system design, and vibration control; advancements in these technologies have significantly improved the stability of equipment operation and processing efficiency.

[0004] In recent years, cloth wheel polishing equipment has gradually developed towards automation, digitalization, and intelligence. For example, by introducing robotic arms, automatic loading and unloading systems, and intelligent sensors, processing parameters can be automatically adjusted; by combining machine vision and artificial intelligence algorithms, the process can be further optimized and online surface quality detection can be achieved. In addition, in terms of safety and environmental protection, modern equipment also pays more attention to operator protection, dust collection, and noise control to meet increasingly stringent occupational health and environmental regulations.

[0005] However, despite significant advancements in the aforementioned areas, most cloth wheel polishing equipment still faces several key unresolved issues in actual production. Specifically, the polishing process still relies on manual waxing, making it difficult to precisely control the timing and amount of wax applied, thus affecting process consistency and processing quality. Furthermore, the high degree of manual involvement throughout the polishing process not only leads to high labor intensity and costs but also increases safety risks due to frequent operations. Waxing operations, especially near the high-speed rotating cloth wheel, pose a potential danger to operators.

[0006] Therefore, how to design a cloth wheel polishing equipment that can automatically control the waxing cycle, realize automatic waxing of the cloth wheel, and further complete the fully automatic polishing process has become a technical problem that the industry urgently needs to solve.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] Reference Figures 1-3As shown in the preferred embodiment of this utility model, a cloth wheel polishing device includes a machine base 1. The machine base 1 is equipped with a polishing mechanism 2, a waxing mechanism 3, and a clamping mechanism 5. The clamping mechanism 5 is used to clamp the workpiece to be polished and can drive the workpiece to be polished to the polishing station of the polishing mechanism 2. The waxing mechanism 3 is connected to a driving mechanism 4, which drives the waxing mechanism 3 to move to the cloth wheel of the polishing mechanism 2, and makes the wax block on the waxing mechanism contact the cloth wheel to achieve waxing. This achieves fully automated integration of polishing and waxing. The clamping mechanism automatically moves the workpiece to the polishing station, and the dedicated driving mechanism drives the waxing mechanism to wax the cloth wheel, completely replacing the traditional operation mode that relies on manual waxing and handling. This results in a significant increase in production efficiency, a substantial reduction in labor costs, and eliminates problems such as uneven waxing and workpiece damage caused by manual operation, ensuring the consistency and stability of product polishing quality.

[0022] As a preferred embodiment of this utility model, it may also have the following additional technical features: the polishing mechanism 2 includes a motor 201 mounted on the machine base 1, the output end of the motor 201 is connected to a rotating shaft 202, the end of the rotating shaft 202 is fixed to the cloth wheel 203, and a wax block limiting plate 204 is provided on the side of the cloth wheel 203 for positioning and cooperating with the wax block during waxing by the waxing mechanism. Thus, when the wax pushing mechanism pushes the wax block towards the cloth wheel, the wax block limiting plate acts as a sturdy support point, resisting the impact force generated by the rotation of the cloth wheel, preventing the wax block from tilting, shaking, or being damaged, thereby ensuring that the wax can be evenly and stably applied to the surface of the cloth wheel, providing structural assurance for the quality of waxing.

[0023] In this embodiment, the waxing mechanism 3 includes a slide plate 301 slidably mounted on the machine base 1 via a guide rail. A support column 302 is vertically mounted on the slide plate 301, and a fixing plate 303 is fixed to the top of the support column 302. A wax-pushing mechanism for pushing wax blocks toward the cloth wheel is mounted on the fixing plate 303. Thus, the combination of the guide rail, slide plate, support column, and fixing plate forms a rigid support frame, ensuring the stability of the entire waxing mechanism during movement and operation. This structure effectively absorbs vibration and provides a stable mounting platform for the wax-pushing mechanism, thereby ensuring the accuracy of the wax block pushing action.

[0024] In this embodiment, the wax-pushing mechanism 6 includes a cylinder 601 mounted on the fixed plate 303. A wax block holder 602 is mounted on the output end of the cylinder, and the wax block holder 602 is used to fix the wax block. The wax block fixed by the wax block holder 602 corresponds to the position of the wax block limiting plate 204. Thus, the waxing action is automated, programmed, and controllable. The wax block holder can firmly fix the wax block and prevent it from loosening during operation.

[0025] In this embodiment, the drive mechanism 4 is a slide module, which is mounted on the machine platform and connected to the slide plate 301, and is used to drive the waxing mechanism 3 to move in the horizontal plane. This allows the waxing mechanism to quickly and accurately reach the designated waxing position in front of the cloth wheel, ensuring that the waxing position remains consistent each time, thereby ensuring the uniformity of the waxing effect.

[0026] In this embodiment, the slide module includes a support frame 401 mounted on the bottom of the machine base. The support frame 401 is provided with a first linear module 402 and a second linear module 403 arranged perpendicularly to each other in a horizontal plane. This allows the equipment to flexibly adjust the waxing contact point according to the wear condition of the cloth wheel or different process requirements, greatly enhancing the equipment's process adaptability and flexibility.

[0027] In this embodiment, a partition plate is provided between the first linear module 402 and the second linear module 403. Both the first and second linear modules include a servo motor and a ball screw assembly driven by the servo motor. The partition plate is connected to the nut of the ball screw assembly. This effectively isolates the two linear modules, preventing dust and debris generated by one module (especially the module near the grinding area) from contaminating and intruding into the other module. This protects precision transmission components, reduces the failure rate, and extends the service life of the entire drive mechanism.

[0028] In this embodiment, the clamping mechanism 5 is a multi-joint robot mounted on the machine base 1. The end effector of the multi-joint robot is equipped with a workpiece fixture for clamping the workpiece to be polished. Thus, it can mimic human arm movements and, through programming, realize complex, multi-angle polishing paths, easily handling work with complex curved surfaces.

[0029] In this embodiment, a dust emission pipe 7 is also included. The dust emission pipe 7 is installed at the bottom of the machine base 1 and is connected to a perforated hole 8 opened on the machine base. The perforated hole 8 is located directly below the cloth wheel. Thus, the dust is collected and treated at the source during the grinding process.

[0030] The working principle of this invention is as follows: During use, the positional relationship between the wax and the cloth wheel is achieved through PLC control of the sliding table module. First, the PLC controls the sliding table module to make the wax block hit the wax limiting plate, thus achieving the reference position positioning of the wax. Then, the PLC controls the sliding table module to move the wax pushing mechanism towards the cloth wheel. When the wax pushing mechanism reaches the waxing position, the cylinder of the wax pushing mechanism is activated, pushing the wax block to make contact between the wax block and the cloth wheel, thereby increasing the contact force between the wax block and the cloth wheel, thus achieving the waxing function. After waxing is completed, the PLC controls the sliding table module to make the wax pushing mechanism return to the rear of the wax limiting plate, which is the initial position of the wax pushing mechanism. Then, the robot clamps the product for uniform and efficient polishing. This process continues until the next push-pull cycle, repeating continuously. Through PLC control, the waxing cycle is controlled, ensuring automatic and uniform waxing each time.

[0031] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0032] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
