[0017] Explanation of reference numerals in the attached figures Detailed Implementation

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] The polishing auxiliary device of this utility model is described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, this utility model provides a polishing auxiliary device 100, which is used for auxiliary processing of a workpiece 200 to be polished. The polishing auxiliary device 100 includes a planetary wheel 10 and a workpiece clamping assembly 20. The planetary wheel 10 has an installation port 11. The workpiece clamping assembly 20 is rotatably disposed in the installation port 11 and can rotatably between a first polishing position and a second polishing position, so that different surfaces of the workpiece 200 to be polished held by the workpiece clamping assembly 20 can face the opening direction of the installation port 11.

[0021] It should be noted that the polishing auxiliary device 100 of this utility model can be used in polishing equipment to assist in the polishing of workpieces. The workpieces to be polished can be flat workpieces, curved workpieces, or composite surface workpieces, etc. This utility model does not limit the type and shape of the workpieces to be polished. This embodiment of the utility model only uses the polishing auxiliary device 100 to assist in polishing, such as... Figure 8 Taking the polishing part 200 as an example, the polishing part 200 has a first processing surface 201 and a second processing surface 202 arranged opposite to each other, and a processing groove 203 is provided on the polishing part 200. The first processing surface 201, the second processing surface 202 and the groove wall of the processing groove 203 all need to be polished. The polishing auxiliary device 100 of this utility model can assist the polishing equipment in polishing the first processing surface 201, the second processing surface 202 and the groove wall of the processing groove 203 respectively.

[0022] Specifically, the polishing auxiliary device 100 includes a planetary wheel 10 with a mounting port 11, and a workpiece clamping assembly 20 rotatably disposed within the mounting port 11. The workpiece clamping assembly 20 is used to clamp the workpiece 200 to be polished and drive the workpiece 200 to be polished to rotate between a first polishing position and a second polishing position. When the workpiece clamping assembly 20 is rotated to the first polishing position, it drives the first processing surface 201 of the workpiece 200 to rotate toward the opening direction of the mounting port 11, such as... Figure 1As shown, this allows the polishing equipment to polish the first processing surface 201 of the workpiece 200; and when the workpiece clamping assembly 20 is rotated to the second polishing position, it drives the second processing surface 202 of the workpiece 200 to rotate toward the opening direction facing the mounting port 11, as shown. Figure 2 As shown, this allows the polishing equipment to polish the second processing surface 202 of the workpiece 200. In the polishing auxiliary device 100 of this embodiment, the workpiece clamping assembly 20 drives the workpiece 200 to rotate, so that different surfaces of the workpiece 200 can be rotated to face the opening of the mounting port 11, thereby facilitating the polishing of different surfaces of the workpiece 200 separately, meeting the requirements for composite surface polishing of the workpiece 200, and improving the convenience and flexibility of the polishing process. Furthermore, during the rotation of the workpiece clamping assembly 20 between the first polishing position and the second polishing position, the workpiece clamping assembly 20 can synchronously drive the workpiece 200 to rotate, so that the polishing equipment can polish the wall of the processing groove 203, further increasing the polishing area and polishing range.

[0023] Furthermore, such as Figure 7 As shown, the polishing equipment includes a grinding device 300 and a rotation drive mechanism. The rotation drive mechanism is driven to connect with the planetary wheel 10 and is used to drive the planetary wheel 10 to rotate. The grinding device 300 includes a brush disk 301 and a grinding drive mechanism 302. The brush disk 301 is located above the planetary wheel 10. The grinding drive mechanism 302 is driven to connect with the brush disk 301 and is used to drive the brush disk 301 to rotate. The brush disk 301 rotates to polish the workpiece 200 to be polished, which is clamped on the workpiece clamping assembly 20.

[0024] Understandably, during rotation, the brush disk 301 can actuate the workpiece clamping assembly 20, causing the workpiece clamping assembly 20 to swing between the first polishing position and the second polishing position. This allows the workpiece clamping assembly 20 to be driven to swing by the rotation of the brush disk 301, thereby enabling the brush disk 301 to polish the first processing surface 201, the second processing surface 202, and the groove wall of the processing groove 203 of the workpiece 200 respectively. This achieves the polishing of multiple different surfaces of the workpiece 200, greatly improving the convenience and flexibility of polishing.

[0025] In this embodiment of the utility model, the planetary wheel 10 includes a wheel body 12 and a mounting rod 13. The wheel body 12 has a mounting opening 11, and the mounting rod 13 is disposed in the mounting opening 11. The workpiece clamping assembly 20 is rotatably disposed on the mounting rod 13. The mounting rod 13 has a rotatable limiting groove 131, and the workpiece clamping assembly 20 has a sliding pin 21, which is slidably disposed in the rotatable limiting groove 131.

[0026] like Figures 3 to 6 As shown, the wheel body 12 has a mounting port 11 for mounting the workpiece clamping assembly 20, and a mounting rod 13 is provided in the mounting port 11. The workpiece clamping assembly 20 is rotatably connected to the mounting rod 13 so that it can swing between a first polishing position and a second polishing position. The mounting rod 13 has an arc-shaped swing limiting groove 131. A sliding pin 21 is connected to the workpiece clamping assembly 20. The sliding pin 21 extends into the swing limiting groove 131 and can slide along the extension direction of the swing limiting groove 131. The sliding engagement between the sliding pin 21 and the swing limiting groove 131 guides the workpiece clamping assembly 20 to swing. The workpiece clamping assembly 20 can drive the workpiece 200 to be polished to rotate, thereby facilitating the polishing of different surfaces of the workpiece 200, such as the first processing surface 201, the second processing surface 202, and the groove wall of the processing groove 203. Furthermore, the two ends of the swing limiting groove 131 each have two groove sidewalls, and the sliding pin 21 abuts against the two groove sidewalls of the swing limiting groove 131 to restrict the swing of the workpiece clamping assembly 20. This ensures that the workpiece clamping assembly 20 can only swing between the first polishing position and the second polishing position. The swing is stable and reliable, ensuring that the workpiece 200 to be polished can always contact the brush disk 301 and be polished.

[0027] In this embodiment of the utility model, the workpiece clamping assembly 20 includes a swing clamping plate 22 and a connecting clamping plate 23. The swing clamping plate 22 is rotatably mounted on the mounting rod 13, and the sliding pin 21 is mounted on the swing clamping plate 22. The connecting clamping plate 23 is detachably connected to the swing clamping plate 22 and clamps the workpiece 200 to be polished.

[0028] like Figure 3 and Figure 6 As shown, the swaying clamp 22 is swayably mounted on the mounting rod 13 and can sway relative to the mounting rod 13. One end of the sliding pin 21 is connected to the swaying clamp 22, and the other end of the sliding pin 21 extends into the swaying limiting groove 131 and can slide within the swaying limiting groove 131 to guide the swaying path of the swaying clamp 22. The connecting clamp 23 is used to connect with the swaying clamp 22, and the connecting clamp 23 and the swaying clamp 22 respectively abut against the two sides of the workpiece 200 to be polished to cooperate in clamping the workpiece 200 to be polished, so that the swaying clamp 22 can drive the connecting clamp 23 and the workpiece 200 to be polished to sway between the first polishing position and the second polishing position, realizing the polishing of multiple different surfaces of the workpiece 200. The connecting clamp 23 and the swaying clamp 22 are detachably connected, which is convenient and quick to connect and improves the ease of disassembly and assembly of the workpiece 200 to be polished.

[0029] Furthermore, such as Figures 1 to 3As shown, there are two mounting rods 13, which are spaced apart along the length of the mounting opening 11. The two ends of the swing clamp 22 are connected to the two mounting rods 13 respectively, which increases the connection strength and improves the structural stability.

[0030] In this embodiment of the utility model, there is a clamping space between the swing clamping plate 22 and the connecting clamping plate 23 for placing the workpiece 200 to be polished. The side of the swing clamping plate 22 facing away from the clamping space has a first clearance portion 221 arranged in an arc shape, and the side of the connecting clamping plate 23 facing away from the clamping space has a second clearance portion 231 arranged in an arc shape.

[0031] like Figure 3 and Figure 6 As shown, when the connecting clamp 23 is connected to the swing clamp 22, a clamping space is formed between the connecting clamp 23 and the swing clamp 22. The clamping space is used to place the workpiece 200 to be polished, so that the connecting clamp 23 and the swing clamp 22 respectively abut against the two sides of the workpiece 200 to be polished and clamp the workpiece 200 to be polished. The clamping is stable and reliable, effectively preventing the workpiece 200 to be polished from loosening. The swing clamp 22 is provided with a first clearance part 221, and the connecting clamp 23 is provided with a second clearance part 231. The first clearance part 221 and the second clearance part 231 are both arc-shaped and located on the side opposite to the clamping space. This allows the first clearance part 221 and the second clearance part 231 to avoid the brush disk 301 when the brush disk 301 polishes the workpiece 200, increasing the contact area between the brush disk 301 and the workpiece 200 to be polished, which is beneficial to improving the polishing effect.

[0032] Furthermore, the connecting clamp 23 and the corresponding swing clamp 22 cooperate to form a cylindrical shape. For example... Figure 3 and Figure 6 As shown, when the connecting clamp 23 is connected to the swing clamp 22, it forms a cylindrical shape with the swing clamp 22. The cylindrical workpiece clamping assembly 20 can not only avoid the brush disk 301, increase the contact area between the brush disk 301 and the workpiece 200 to be polished, and improve the polishing effect, but also has the advantages of being easy to process and reduce the difficulty of production.

[0033] In this embodiment of the utility model, the mounting rod 13 includes a mounting section 132 and a connecting section 133. A swing limiting groove 131 is formed on the mounting section 132. The mounting section 132 is also provided with a mounting hole 1321. The swing clamp 22 is provided with a rotating pin 222, which is rotatably disposed in the mounting hole 1321. The wheel body 12 is also provided with a groove 121, which communicates with the mounting opening 11. The connecting section 133 is embedded in the groove 121.

[0034] like Figure 4 and Figure 5As shown, the mounting section 132 has an arc-shaped swing limiting groove 131. The swing limiting groove 131 is used for the sliding pin 21 to extend into and cooperate with the sliding pin 21 to guide the swing clamp 22 to swing. The mounting section 132 also has mounting holes 1321. The swing limiting grooves 131 are spaced around the outer periphery of the mounting holes 1321. One end of the rotating pin 222 is connected to the swing clamp 22, and the other end of the rotating pin 222 extends into the mounting hole 1321 and can rotate within the mounting hole 1321, so that the swing clamp 22 can swing. The rotating pin 222 is used as the rotation center to drive the connecting clamp 23 and the workpiece 200 to be polished to swing. The swing is smooth and stable. Furthermore, each end of the mounting section 132 is provided with a connecting section 133. The wheel body 12 is provided with a groove 121 corresponding to each connecting section 133. The groove 121 is connected to the mounting port 11 but does not penetrate the wheel body 12, so that the connecting section 133 can be embedded into the corresponding groove 121 and connected to the bottom wall of the groove 121 by fasteners. The connection is stable and reliable, effectively preventing the mounting rod 13 from loosening.

[0035] Furthermore, a positioning groove 1211 is provided on the bottom wall of the groove 121, a positioning pin 1212 is provided in the positioning groove 1211, and a through hole 1331 is provided on the connecting section 133 for the positioning pin 1212 to pass through. Figure 4 and Figure 5 As shown, a positioning groove 1211 is provided on the bottom wall of the groove 121. A through hole 1331 is provided on the connecting section 133 at the position corresponding to the positioning groove 1211. The positioning pin 1212 passes through the through hole 1331 and extends into the positioning groove 1211. The positioning pin 1212 cooperates with the through hole 1331 and the positioning groove 1211 to play the role of positioning and installing the mounting rod 13, which improves the ease of assembly.

[0036] In this embodiment of the utility model, the workpiece clamping assembly 20 further includes a support pin 24, which is connected between the swing clamping plate 22 and the connecting clamping plate 23 and supports the workpiece 200 to be polished. Figure 6 As shown, one end of the support pin 24 is connected to the swing clamping plate 22, and the other end of the support pin 24 is connected to the connecting clamping plate 23. The workpiece 200 to be polished is supported on the support pin 24 when the connecting clamping plate 23 is connected to the swing clamping plate 22. The support pin 24 plays a role in stably supporting the workpiece 200 to be polished, effectively preventing the workpiece 200 to be polished from falling. In addition, there are multiple support pins 24. Multiple support pins 24 are spaced apart along the length direction of the swing clamping plate 22 and are all used to support the workpiece 200 to be polished. This makes the horizontal height of the workpiece 200 extending out of the clamping space consistent, and the workpiece 200 to be polished is in uniform contact with the brush disk 301 in the length direction of the swing clamping plate 22, which improves the consistency of the polishing process.

[0037] In the embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the mounting port 11 is configured as a through hole penetrating the surface of the planetary wheel 10, that is, the mounting port 11 is configured to penetrate the wheel body 12, so as to facilitate chip removal and prevent polishing waste from accumulating on the surface of the wheel body 12; in addition, the planetary wheel 10 is also provided with a clearance opening 14, which is connected to the mounting port 11, and the number of clearance openings 14 is set to two. The two clearance openings 14 are spaced apart on both sides of the mounting port 11 along the width direction of the mounting port 11. The clearance openings 14 are used to avoid the workpiece clamping assembly 20 and the workpiece 200 to be polished, so that the operator can disassemble and install the workpiece clamping assembly 20 and pick up and put down the workpiece 200 to be polished from the clearance opening 14, which improves the ease of use.

[0038] In this embodiment of the utility model, the number of workpiece clamping assemblies 20 is set to multiple, and the multiple workpiece clamping assemblies 20 are arranged at intervals within the mounting opening 11. For example Figures 1 to 3 As shown, the mounting port 11 is provided with multiple workpiece clamping assemblies 20. The multiple workpiece clamping assemblies 20 are spaced apart in the mounting port 11 along the width direction and are respectively rotatably connected to the mounting rod 13. Each workpiece clamping assembly 20 can be used to clamp the workpiece 200 to be polished so as to simultaneously perform batch polishing of multiple workpieces 200, which greatly improves the polishing efficiency.

[0039] In addition, this utility model also provides a polishing device, which includes a grinding device 300, a rotation drive mechanism, and a fixture module. The fixture module includes multiple polishing auxiliary devices 100 as described above. The planetary wheels 10 of the multiple polishing auxiliary devices 100 are arranged circumferentially at intervals. The rotation drive mechanism can drive the multiple planetary wheels 10 to revolve and drive any one planetary wheel 10 to rotate. The grinding device 300 includes a brush disk 301 and a grinding drive mechanism 302. The brush disk 301 is disposed above the multiple polishing auxiliary devices 100. The grinding drive mechanism 302 can drive the brush disk 301 to rotate and drive any one of the workpiece clamping components 20 to swing between the first polishing position and the second polishing position.

[0040] like Figure 7As shown, the fixture module includes multiple polishing auxiliary devices 100. The planetary wheels 10 of the multiple polishing auxiliary devices 100 are circumferentially spaced and driven by a rotational drive mechanism. This allows the rotational drive mechanism to drive any one planetary wheel 10 to rotate around its own central axis, and to drive multiple planetary wheels 10 to revolve around the central axis of the brush disk 301. The brush disk 301 is positioned above the fixture module. A grinding drive mechanism 302 is driven by the brush disk 301 and can drive the brush disk 301 to rotate. During rotation, the brush disk 301 can actuate the workpiece clamping assembly 20 on any one of the planetary wheels 10, causing the workpiece clamping assembly 20 to rotate and hold the workpiece to be polished. The polishing component 200 rotates between the first polishing position and the second polishing position. During the rotation, the brush disk 301 can contact different surfaces of the workpiece 200 and perform polishing. This allows the composite surfaces of the workpiece 200 to be polished to be polished simply by rotating the brush disk 301, eliminating the need for an additional rotating drive component to drive the workpiece clamping assembly 20. This saves costs and significantly improves the convenience and flexibility of polishing. Furthermore, the specific structure of the polishing auxiliary device 100 is as described in the above embodiments. Since the polishing equipment adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0041] Furthermore, such as Figure 7 As shown, the brush disk 301 is provided with a lifting drive component that is driven to drive the brush disk 301. The lifting drive component is used to drive the brush disk 301 to rise and fall, so that the brush disk 301 is lowered to be driven to connect with the grinding drive mechanism 302 or raised to be disconnected from the grinding drive mechanism 302. When the grinding drive mechanism 302 is driven to connect with the brush disk 301, it can drive the brush disk 301 to rotate to polish the workpiece 200 to be polished. When the brush disk 301 is disconnected from the grinding drive mechanism 302, the brush disk 301 and the grinding drive mechanism 302 are vertically spaced apart to facilitate the picking and placing of the workpiece 200 to be polished.
