[0002] In the manufacturing industry, polishing is a key process for improving the surface quality of products and is widely used in the processing of materials such as metals, glass, and ceramics.

[0003] Traditional polishing equipment typically uses a fixed mounting method for the workpiece to be polished, along with polishing tools that have a single movement mode and a relatively fixed path. This operating mode results in poor polishing uniformity, with inconsistent polishing effects in different areas; at the same time, the polishing efficiency is also relatively low. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a polishing device, the specific solution of which is as follows:

[0005] A polishing apparatus, comprising:

[0017] In an optional embodiment, the mounting component further includes:

[0018] The locking part is rotatably connected to the mounting part and is used to fasten the connection between the workpiece to be polished and the mounting part.

[0019] In an optional embodiment, the polishing assembly further includes:

[0031] Beneficial effects: This application, by setting a polishing component that can be switched to be close to or far from the mounting part, can flexibly adjust the contact state between the polishing part and the workpiece to be polished, improving the flexibility and convenience of the polishing operation. By driving the mounting component and the polishing component separately, the mounting part and the polishing part can be driven to rotate synchronously.

[0046] Example 1

[0047] As per the instruction manual Figure 1 Included with instruction manual Figure 2 As shown, the polishing device provided in this embodiment includes: a mounting component 1, a polishing component 2, and a driving component 3. The components work together to achieve efficient polishing of the workpiece to be polished.

[0048] The mounting assembly 1 is provided with a mounting part 10 for mounting the workpiece to be polished;

[0049] The polishing assembly 2 is provided with a polishing part 20 for polishing the workpiece to be polished in an area near the mounting assembly 1; the polishing assembly 2 can switch between positions close to and far from the mounting assembly 10, and when the polishing assembly 2 is close to the mounting assembly 10, the polishing part 20 abuts against the workpiece to be polished to form a polishing contact;

[0050] The driving component 3 drives the mounting component 1 and the polishing component 2 respectively. When the polishing part 20 comes into contact with the workpiece to be polished, the driving component 3 synchronously drives the mounting part 10 and the polishing part 20 to rotate, thereby polishing the workpiece to be polished.

[0051] Specifically, in some embodiments, the mounting component 1 is highly adjustable, and the material (e.g., high-strength aluminum alloy), size, and shape of the mounting part 1 can be adjusted according to actual needs to adapt to polishing parts of different shapes and sizes.

[0052] Optionally, the mounting part 1 may be provided with a pin hole for mounting the workpiece to be polished. After the workpiece to be polished is inserted into the pin hole, it is fastened by the locking part 14 to achieve stable mounting of the workpiece to be polished.

[0053] Mounting component 1 provides a stable mounting platform for the workpiece to be polished, ensuring its stability during the polishing process and avoiding uneven polishing or damage caused by vibration or displacement, thereby improving polishing quality and efficiency.

[0054] As a key component for performing the polishing action, the polishing assembly 20 is made of a highly wear-resistant and high-hardness material (e.g., high-hardness diamond). Optionally, the polishing part 20 can be a polishing wheel structure, an abrasive belt structure, or other polishing structures to ensure a uniform and efficient polishing effect when in contact with the workpiece. In some embodiments, the rotational speed and pressure of the polishing part 20 can be controlled and adjusted by an adjusting device, allowing the polishing parameters to be adjusted according to the material and surface condition of the workpiece, thereby improving polishing efficiency and quality.

[0055] Furthermore, the polishing component 2 can flexibly switch between being close to and far from the mounting part 10. When the polishing component 2 is close to the mounting part 10, the polishing part 20 can precisely abut against the surface of the workpiece to be polished, forming a stable polishing contact surface, thereby achieving precise control of the polishing process and improving polishing efficiency and quality.

[0056] The drive assembly 3 is connected to both the mounting assembly 1 and the polishing assembly 2. When the polishing part 20 comes into contact with the workpiece to be polished, the drive assembly 3 can synchronously drive the mounting part 10 and the polishing part 20 to rotate at a coordinated speed. This synchronous rotation ensures that the workpiece to be polished receives uniform and continuous friction during the polishing process, thereby achieving a highly efficient and uniform polishing effect. It also reduces polishing defects such as scratches and burns caused by mismatched speeds or asynchronous drives, further improving polishing quality and product qualification rate.

[0057] In some embodiments, the drive component 3 may include a motor and a reducer. The motor may be a high-performance servo motor, characterized by stable speed and rapid response. The reducer may be a planetary gear reducer, capable of converting the high speed of the motor into a low speed suitable for polishing operations.

[0058] Furthermore, a synchronization controller can be set in the drive assembly 3 to monitor the rotation speed of the mounting part 10 and the polishing part 20 in real time, and ensure that the mounting part 10 and the polishing part 20 rotate synchronously at the same speed by adjusting the output power of the motor, thereby achieving a high-efficiency and uniform polishing effect.

[0059] During use, the user lifts the polishing component 2 to the preset polishing position using the handheld part 4, so that the polishing part 2 and the surface of the workpiece to be polished come into contact, and the drive component 3 is activated to drive the mounting part 10 and the polishing part 20 to rotate synchronously, thereby achieving efficient polishing of the workpiece to be polished; after the polishing action is completed, the user lowers the polishing component 2 to the starting position using the handheld part 4, which is easy to operate and improves polishing efficiency.

[0060] In an optional embodiment, the driving component 3 includes:

[0061] The first driving unit 30 is connected to the mounting assembly 1 and is used to drive the mounting unit 10 to rotate the workpiece to be polished in a preset first direction.

[0062] The second drive unit 31 is connected to the polishing assembly 2 and is used to drive the polishing unit 20 to rotate in a preset second direction.

[0063] In an optional embodiment, the preset first direction is opposite to the preset second direction.

[0064] In some embodiments, to achieve precise driving of the mounting section 10 and the polishing section 20, the drive assembly 3 can adopt a dual-drive structure. Specifically, the first drive section 30 can be composed of a servo motor and connected to the mounting section 10 via a coupling. The servo motor features high torque output, low noise operation, and fast response, ensuring the stability and accuracy of the mounting section 10 during rotation. Furthermore, to further improve transmission efficiency, a reduction gear set can be provided between the coupling and the mounting section 10 to adjust the speed and torque according to actual polishing requirements, ensuring that the workpiece to be polished can contact the polishing section 20 evenly, thereby significantly improving polishing quality and efficiency.

[0065] Furthermore, the second drive unit 31 can be composed of a high-performance variable frequency motor. Variable frequency motors have the characteristics of wide speed range, stable operation, and convenient maintenance, and can adjust the speed in real time according to the actual needs during the polishing process. The variable frequency motor allows the speed of the polishing unit 20 to be flexibly adjusted according to factors such as polishing material, polishing fluid concentration, and polishing time, thereby further optimizing the polishing effect.

[0066] Furthermore, the rotation directions of the mounting part 10 and the polishing part 20 can be opposite (for example, the first driving part 30 drives the mounting part 10 to rotate clockwise, and the second driving part 31 drives the polishing part 20 to rotate counterclockwise). The opposite rotation directions increase the relative motion speed between the workpiece to be polished and the polishing part 20, which can remove impurities from the workpiece surface more quickly, shorten the polishing time, and thus improve the polishing efficiency.

[0067] In an optional embodiment, as shown in the appendix to the specification... Figure 3 As shown, the installation component 1 further includes:

[0068] The first drive wheel 11 drives the drive assembly 3;

[0069] The first driven wheel 12 is drivenly connected to the first driving wheel 11, and the first driven wheel 12 is drivenly connected to the mounting part 10;

[0070] The transmission belt 13 is respectively sleeved around the first driving wheel 11 and the first driven wheel 12. The transmission belt 13 is used to drive the first driven wheel 12 to rotate under the drive of the first driving wheel 11, thereby driving the mounting part 10 to rotate.

[0071] In some embodiments, the first drive pulley 11 is typically made of a high-strength, wear-resistant metal (such as 45# steel), and its surface is precision-machined to ensure a good coefficient of friction with the transmission belt 13. The first drive pulley 11 can be connected to the drive assembly 3 via a coupling to ensure efficient power transmission. The first driven pulley 12 is also made of metal and is matched with the first drive pulley 11 and the transmission belt 13 to ensure smooth transmission. Simultaneously, the first driven pulley 12 and the mounting portion 10 can be connected via bearings.

[0072] Furthermore, the transmission belt 13 can be made of high-strength, high-elasticity rubber or polyurethane material, and its surface is specially treated to improve the friction between it and the first driving pulley 11 and the first driven pulley 12. The width and thickness of the transmission belt 13 can be reasonably selected according to parameters such as transmission power and speed to ensure the reliability and stability of the transmission.

[0073] In an optional embodiment, the mounting component 1 further includes:

[0074] The locking part 14 is rotatably connected to the mounting part 10 and is used to fasten the connection between the workpiece to be polished and the mounting part 10.

[0075] In some embodiments, the locking part 14 may be a threaded rotary handle or knob structure, and its interior may be threadedly connected to the corresponding threaded hole on the mounting part 10 through the thread. By rotating the locking part 14, its axial movement relative to the mounting part 10 can be realized.

[0076] After the workpiece to be polished is installed in the mounting part 10, the locking part 14 is rotated to move it toward the mounting part 10. The end of the locking part 14 will gradually press against the workpiece to be polished, thereby generating a clamping force between the two. This can effectively eliminate the small gap between the workpiece to be polished and the mounting part 10, ensuring that the workpiece to be polished will not shake or shift during the polishing process, thus improving the stability and accuracy of the polishing operation.

[0077] In an optional embodiment, as shown in the appendix to the specification... Figure 4 As shown, the polishing assembly 2 further includes:

[0078] The second drive wheel 21 drives the drive assembly 3;

[0079] The second driven wheel 22 is driven by the second driving wheel 21, and the second driven wheel 22 is driven by the polishing part 20, so as to drive the polishing part 20 to rotate under the drive of the second driving wheel 21.

[0080] In some embodiments, the second driving wheel 21 and the second driven wheel 22 can be made of a high-strength, wear-resistant metal material (such as 45# steel). Depending on different polishing requirements, the rotational speed and torque of the polishing section 20 can be adjusted by changing the transmission ratio of the second driving wheel 21 and the second driven wheel 22. For example, when fine polishing of the workpiece is required, the transmission ratio can be appropriately increased to reduce the rotational speed of the polishing section 20 while increasing the torque, allowing the polishing section 20 to process the workpiece surface more gently and precisely, resulting in a higher surface finish.

[0081] In an optional embodiment, the polishing section 20 includes an abrasive belt;

[0082] The polishing assembly 2 further includes a tensioning wheel 23, which is connected to the abrasive belt to form a preload on the abrasive belt.

[0083] Abrasive belts, as flexible polishing tools, are composed of a substrate, abrasive particles, and a binder. The substrate is typically made of a soft yet strong material, such as cloth, paper, or polyester film, providing the belt with the necessary flexibility and load-bearing capacity. The abrasive particles are crucial for achieving the polishing function; common types include alumina, silicon carbide, and diamond, with different particle sizes suitable for varying polishing precision requirements. The binder securely holds the abrasive particles to the substrate. The flexible nature of abrasive belts allows them to closely conform to the surfaces of workpieces with various complex shapes, achieving uniform and effective polishing whether flat, curved, or irregularly shaped.

[0084] In some embodiments, the tensioning wheel 23 may include a wheel body and bearings. The wheel body is typically made of metal with a precision-machined surface to ensure uniform friction and minimal wear when in contact with the sanding belt. The bearing may be a rolling bearing to ensure that the tensioning wheel 23 can rotate freely and reduce rotational resistance. Specifically, the tensioning wheel 23 is connected to the sanding belt, for example, with single-sided or double-sided tensioning, thereby applying a preload to the sanding belt. The stable preload ensures a constant contact pressure between the sanding belt and the workpiece surface, thus achieving a uniform polishing effect.

[0085] In an optional embodiment, the polishing apparatus further includes:

[0086] The handheld part 4 is fixedly mounted on the polishing component 2. The handheld part 4 is used to drive the polishing component 2 to switch between approaching and moving away from the mounting part 10 under the action of external force.

[0087] In some embodiments, the handgrip 4 typically employs an ergonomic structure, such as an arc-shaped grip or a straight handle with anti-slip texture. The handgrip 4 is fixedly connected to the polishing assembly 2 (e.g., by bolts, welding, or snap-fit) to ensure a tight fit during operation of the polishing device, preventing loosening or displacement. By applying external force through the handgrip 4, the operator can easily and precisely control the polishing assembly 2 to move closer to and further away from the mounting portion 10, simplifying operation and improving polishing efficiency.

[0088] In an optional embodiment, the polishing apparatus further includes:

[0089] The processing platform 5, and the mounting component 1 is fixedly mounted on the processing platform 5;

[0090] The fixing component 6 is fixedly disposed on the processing platform 5, and the side of the fixing component 6 away from the processing platform 5 is movably connected to the polishing component 2.

[0091] The processing platform 5 is the basic support structure of the entire polishing device, providing a reliable mounting position for other components and ensuring that polishing operations can be carried out in a stable environment. In some embodiments, the processing platform 5 can be made of high-strength, wear-resistant metal materials, such as cast iron or stainless steel. Furthermore, the processing platform 5 is generally rectangular or square in shape to ensure that the components mounted on it remain level, preventing the entire device from shaking due to vibration or external forces during polishing, thereby guaranteeing the stability and consistency of polishing quality.

[0092] Furthermore, the polishing component 2 is mounted on the processing platform 5 via the fixing component 6 and is movably connected to the fixing component 6, for example, through a sliding connection or a rotary connection. In an optional embodiment, the polishing component 2 is rotatably connected to the fixing component 6, thereby enabling the polishing component 2 to switch between being closer to or farther from the mounting part 10. Furthermore, to achieve precise adjustment and fixation of the position of the polishing component 2, the fixing component 6 may also be equipped with an adjustment and locking mechanism (e.g., a manual adjustment knob or handle, or an electric adjustment device such as a stepper motor or servo motor), thereby ensuring that the polishing component 2 remains stable during high-speed polishing.

[0093] In an optional embodiment, the polishing apparatus further includes:

[0094] A switch assembly 7 is electrically connected to the drive assembly 3.

[0095] In some embodiments, the switch assembly 7 may include a mechanical switch (e.g., a push-button, toggle, or knob structure) that is easy to operate and saves time; or it may include an electronic switch (mostly based on touch sensing, infrared sensing, or wireless remote control technology) that improves the flexibility and convenience of operation.

[0096] Furthermore, the switch assembly 7 and the drive assembly 3 are electrically connected to form a complete electrical control circuit. When the operator operates the switch assembly 7 to the on state, current flows from the power source through the switch assembly 7 into the drive assembly 3. After being energized, the drive assembly 3 starts to operate, driving the mounting part 10 and the polishing part 20 to perform polishing operations. When the operator switches the switch assembly 7 to the off state, the circuit is cut off, the drive assembly 3 stops operating, and the polishing operation also stops.

[0097] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model.
