Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing equipment technology, and in particular to a dry grinding and polishing equipment. Background Technology

[0002] In modern manufacturing, surface finishing of workpieces such as metals, ceramics, glass, or composite materials is a crucial process. Grinding and dry polishing (i.e., polishing without coolant) are key means to achieve high surface quality. Pneumatic polishing heads polish product surfaces by rotating at high speed, improving surface smoothness, reducing surface roughness, and increasing surface brightness to meet usage requirements.

[0003] However, traditional structures have significant technical drawbacks. For designs where the workpiece is fixed and the polishing head moves, the drive system needs to support the entire polishing mechanism and its drive components through a wide range of reciprocating motions. This design results in large masses and high inertia in the moving parts, leading to high energy consumption and significant mechanical vibration and impact during start-up, stopping, and reversal. These vibrations are directly transmitted to the contact point between the polishing head and the workpiece, causing unstable polishing pressure and resulting in chatter marks on the workpiece surface, affecting surface finish and generating significant noise pollution in the working environment. While designs with a fixed polishing head and a moving workpiece may reduce vibration, the clamping mechanism still needs to drive the workpiece through complex movements. For large or irregularly shaped workpieces, their mass and inertia may be even greater, similarly causing systemic vibration problems and placing extremely high demands on the rigidity and drive power of the clamping mechanism, resulting in less stable equipment operation.

[0004] Therefore, there is an urgent need in this field for a new type of dry polishing equipment that can effectively distribute the mass of moving parts, reduce the range of motion and inertia of the polishing mechanism, enhance the rigidity of key connection parts, fundamentally suppress vibration and reduce noise from the structural design, and improve the flexibility and efficiency of processing. Utility Model Content

[0005] Therefore, it is necessary to provide a dry polishing equipment to address the technical problem of excessive noise during the operation of existing grinding and polishing equipment.

[0006] A dry polishing and grinding device includes a frame, a worktable, a first drive mechanism, a second drive mechanism, a clamping mechanism, and a polishing mechanism. The worktable is disposed on the top side surface of the frame. The first drive mechanism is disposed on the top side surface of the worktable. The clamping mechanism is installed on the drive end of the first drive mechanism. The second drive mechanism spans the top side of the first drive mechanism and the clamping mechanism. The polishing mechanism is disposed on the drive end of the second drive mechanism.

[0007] The first driving mechanism includes a first linear guide rail, which is laid on the top surface of the worktable along a preset direction. A clamping mechanism is installed on the driving end of the first linear guide rail, enabling the clamping mechanism to reciprocate along the first linear guide rail. The second driving mechanism includes a gantry frame, a second linear guide rail, and a third linear guide rail. The gantry frame is erected perpendicular to the first linear guide rail on the top side of the first linear guide rail and connected to the worktable. The second linear guide rail is installed perpendicular to the first linear guide rail on the top of the gantry frame. The third linear guide rail is installed perpendicular to the driving end of the second linear guide rail on the top surface of the worktable. A polishing mechanism is installed on the driving end of the third linear guide rail.

[0008] In one embodiment, the above-mentioned polishing mechanism includes a first polishing head, which is mounted on the drive end of the third linear guide.

[0009] In one embodiment, the above-mentioned grinding and polishing mechanism further includes a first fixing seat with reinforcing ribs. The first fixing seat is disposed between the first grinding head and the drive end of the third linear guide rail for fixing and installing the first grinding head.

[0010] In one embodiment, the above-mentioned polishing mechanism further includes a fourth linear guide, a second fixed base, and a second polishing head. The fourth linear guide is disposed on the adjacent side of the first fixed base and connected to the drive end of the third linear guide; the second fixed base is mounted on the drive end of the fourth linear guide; and the second polishing head is mounted on the second fixed base.

[0011] In one embodiment, the aforementioned fourth linear guide extends along the direction perpendicular to the top side surface of the worktable.

[0012] In one embodiment, both the first and second grinding heads are pneumatic grinding heads; the dry polishing equipment also includes an air source pressure regulating and filtering unit, which is installed at one end of the frame and its output end is connected to the first and second grinding heads.

[0013] In one embodiment, the first driving mechanism includes two first linear guides, which are arranged parallel to each other on both sides of the top surface of the worktable; the clamping mechanism is configured as two sets, and the two clamping mechanisms are respectively installed to the driving ends of the two first linear guides.

[0014] In one embodiment, a detection component is laid on the adjacent side of each of the first linear guides to monitor the movement status of the clamping mechanism in real time.

[0015] In one embodiment, the detection component includes a mounting track and several photoelectric sensors. The mounting track extends along a corresponding first linear guide rail and is laid on the top surface of the workbench. The several photoelectric sensors are movably disposed at preset positions on the mounting track.

[0016] In one embodiment, each of the above-described detection components has two photoelectric sensors.

[0017] In one embodiment, each of the above clamping mechanisms includes a mounting plate, a limiting plate, a pneumatic gripper, and a fifth linear guide; the mounting plate is mounted on the drive end of the first linear guide; the limiting plate is provided on one side edge of the mounting plate for workpiece mounting; the fifth linear guide is provided on the other side of the mounting plate; and the pneumatic gripper is mounted on the drive end of the fifth linear guide.

[0018] In one embodiment, the aforementioned limiting plate is provided with two mounting holes, each mounting hole being used for mounting the workpiece; each clamping mechanism includes two pneumatic grippers, both of which are mounted on the drive end of the fifth linear guide.

[0019] In one embodiment, each of the above-described clamping mechanisms further includes a dust cover, which is disposed on the top side of the mounting plate and one end of which cooperates with the limiting plate to house the pneumatic gripper and the fifth linear guide rail inside the dust cover.

[0020] In one embodiment, the workbench is provided with a control panel, which is disposed on one side surface of the workbench and is electrically connected to the first drive mechanism, the second drive mechanism, the clamping mechanism and the polishing mechanism.

[0021] In one embodiment, the bottom of the aforementioned frame is provided with several casters.

[0022] The aforementioned dry polishing equipment employs the coordinated motion of a first drive mechanism and a second drive mechanism. The first drive mechanism drives the clamping mechanism and workpiece to reciprocate along a preset direction (e.g., the X-axis), while the second drive mechanism drives the polishing mechanism to move in a vertical direction (e.g., the Z-axis) and another horizontal direction (e.g., the Y-axis), thus distributing the overall motion across the workpiece and the polishing mechanism. The polishing mechanism primarily performs fine position adjustments rather than large-scale movements, thereby significantly reducing its own motion amplitude. This reduction in the polishing mechanism's motion amplitude directly lowers its acceleration and deceleration changes, thereby reducing vibrations caused by inertial forces and effectively reducing the source of mechanical vibration. The drive mechanism adopts a gantry design and is connected to the worktable, providing high rigidity and stability. It can absorb and disperse the vibration energy generated during the grinding process. The dual-axis drive system allows the grinding and polishing mechanism to make smooth and continuous fine-tuning movements, avoiding sudden impacts or jumps. At the same time, the workpiece is driven by the first linear guide rail, and the motion trajectory is preset and smooth, reducing the vibration excitation of the overall system. Thus, through the coordinated movement of the workpiece and the grinding and polishing mechanism, the grinding force is evenly distributed, avoiding local stress concentration and sudden load changes, reducing dynamic instability and resonance phenomena during the grinding process, thereby greatly reducing the noise level during equipment operation.

[0030] Please see Figures 1 to 4This utility model discloses a dry polishing and grinding device 1, which includes a frame 10, a worktable 20, a first drive mechanism 30, a second drive mechanism 40, a clamping mechanism 50, and a polishing and grinding mechanism 60. The worktable 20 is disposed on the top side surface of the frame 10. The first drive mechanism 30 is disposed on the top side surface of the worktable 20. The clamping mechanism 50 is installed on the drive end of the first drive mechanism 30. The second drive mechanism 40 spans the top side of the first drive mechanism 30 and the clamping mechanism 50. The polishing and grinding mechanism 60 is disposed on the drive end of the second drive mechanism 40. Thus, the workpiece to be dry polished and ground is clamped by the clamping mechanism 50 and moves relative to the worktable 20 along a preset trajectory under the drive of the first drive mechanism 30. At the same time, the second drive mechanism 40 drives the polishing and grinding mechanism 60 to move along the preset trajectory in coordination with the clamping mechanism 50, thereby performing dry polishing and grinding operations on the surface of the workpiece. Specifically, the first drive mechanism 30 includes a first linear guide rail 31, which is laid on the top surface of the worktable 20 along a preset direction. A clamping mechanism 50 is installed on the drive end of the first linear guide rail 31, enabling the clamping mechanism 50 to reciprocate along the first linear guide rail 31. Based on this, the second drive mechanism 40 includes a gantry frame 41, a second linear guide rail 42, and a third linear guide rail 43. The gantry frame 41 is erected perpendicular to the first linear guide rail 31 on its top side and connected to the worktable 20. The second linear guide rail 42 is installed perpendicular to the first linear guide rail 31 on the top of the gantry frame 41. The third linear guide rail 43 is installed perpendicular to the drive end of the second linear guide rail 42 on the top surface of the worktable 20. A polishing mechanism 60 is installed on the drive end of the third linear guide rail 43, forming a dual-axis drive mechanism that drives the polishing mechanism 60 to perform a combined translational and lifting motion relative to the worktable 20. Therefore, based on the coordinated operation of the first drive mechanism 30 and the second drive mechanism 40, the relative movement between the clamping mechanism 50 and the grinding and polishing mechanism 60 is achieved while reducing the range of motion of the grinding and polishing mechanism 60, thereby reducing grinding vibration noise.Based on the above configuration, the dry polishing equipment 1 of this solution employs the coordinated motion of a first drive mechanism 30 and a second drive mechanism 40. The first drive mechanism 30 drives the clamping mechanism 50 and the workpiece to reciprocate along a preset direction (e.g., the X-axis), while the second drive mechanism 40 drives the polishing mechanism 60 to move in a vertical direction (e.g., the Z-axis) and another horizontal direction (e.g., the Y-axis). This disperses the overall motion across the workpiece and the polishing mechanism 60. The polishing mechanism 60 primarily performs fine position adjustments rather than large-scale movements, thereby significantly reducing the amplitude of its own motion. This reduction in the amplitude of the polishing mechanism's motion directly reduces its acceleration and deceleration changes, thus reducing vibrations caused by inertial forces and effectively lowering [the vibration level]. The mechanical vibration source; the second drive mechanism 40 adopts a gantry frame 41 design and is connected to the worktable 20, providing high rigidity and stability, which can absorb and disperse the vibration energy generated during the grinding process. The dual-axis drive system allows the grinding and polishing mechanism 60 to make smooth and continuous fine-tuning movements, avoiding sudden impacts or jumps. At the same time, the workpiece is driven by the first linear guide rail 31, and the motion trajectory is preset and smooth, reducing the vibration excitation of the overall system. Thus, through the coordinated movement of the workpiece and the grinding and polishing mechanism 60, the grinding force is evenly distributed, avoiding local stress concentration and sudden load changes, reducing dynamic instability and resonance phenomena during the grinding process, thereby greatly reducing the noise level during equipment operation.

[0031] Furthermore, the polishing mechanism 60 includes a first polishing head 61, which is mounted on the drive end of the third linear guide rail 43. Thus, based on the coordinated drive of the second linear guide rail 42 and the third linear guide rail 43, the first polishing head 61 can perform polishing work on the workpiece clamped in the clamping mechanism 50 along a preset trajectory.

[0032] Specifically, in one embodiment, the polishing mechanism 60 further includes a first fixing seat 62 with reinforcing ribs. The first fixing seat 62 is disposed between the first polishing head 61 and the drive end of the third linear guide rail 43 for fixing the first polishing head 61. Thus, the reinforcing structure based on the first fixing seat 62 can significantly increase the bending and torsional stiffness of the first fixing seat 62, making the connection between the first polishing head 61 and the third linear guide rail 43 a highly rigid whole, thereby greatly improving the natural frequency of the structure and making it less likely to be excited by resonance, thus effectively suppressing such high-frequency vibration and noise.

[0033] Furthermore, the grinding and polishing mechanism 60 also includes a fourth linear guide rail 63, a second fixed base 64, and a second grinding head 65. The fourth linear guide rail 63 is disposed adjacent to the first fixed base 62 and connected to the drive end of the third linear guide rail 43; the second fixed base 64 is installed on the drive end of the fourth linear guide rail 63; and the second grinding head 65 is installed on the second fixed base 64. Thus, while reinforcing the grinding intensity of the first grinding head 61, the second grinding head 65 has a further movement and adjustment function compared to the first grinding head 61, thereby enhancing the grinding and polishing mechanism 60's flexibility in grinding and dry polishing workpieces.

[0034] Specifically, in one embodiment, the fourth linear guide 63 extends along the direction of the top side surface of the vertical worktable 20 to enable further fine-tuning of the lifting and lowering of the second grinding head 65 relative to the worktable 20.

[0035] Furthermore, in one embodiment, both the first grinding head 61 and the second grinding head 65 are pneumatic grinding heads. Correspondingly, the dry polishing equipment 1 also includes an air source pressure regulating and filtering unit 70, which is installed at one end of the frame 10. The output end of the air source pressure regulating and filtering unit 70 is connected to the first grinding head 61 and the second grinding head 65. Thus, the air source pressure regulating and filtering unit 70 can output a stable pressure and volume of air to the first grinding head 61 and the second grinding head 65 to ensure the operational stability of the first grinding head 61 and the second grinding head 65. In practical applications, the first grinding head 61 and the second grinding head 65 can be configured with abrasives of different grit sizes, materials, or shapes. For example, the first grinding head 61 performs rough grinding, and the second grinding head 65 then performs fine polishing, enabling multiple processes to be completed in one machine and one setup, significantly improving processing efficiency. The two grinding heads can also simultaneously perform collaborative grinding on different areas or the same area of ​​the workpiece, accelerating the material removal rate by sharing the grinding force.

[0036] Furthermore, in one embodiment, the first driving mechanism 30 includes two first linear guide rails 31, which are arranged parallel to each other on both sides of the top surface of the worktable 20; correspondingly, the clamping mechanism 50 is configured as two sets, and the two clamping mechanisms 50 are respectively installed on the driving ends of the two first linear guide rails 31, so that the two second linear guide rails 42 can drive the two clamping mechanisms 50 to move independently, thereby increasing the workpiece throughput of the dry polishing equipment 1 in one polishing cycle, and also enhancing the processing flexibility of the dry polishing equipment 1.

[0037] Furthermore, a detection component 80 is laid on the adjacent side of each first linear guide rail 31 to monitor the movement state of the clamping mechanism 50 in real time. Specifically, in one embodiment, the detection component 80 includes a mounting rail 81 and several photoelectric sensors 82. The mounting rail 81 extends along the corresponding first linear guide rail 31 and is laid on the top surface of the worktable 20; the several photoelectric sensors 82 are movably disposed at preset positions on the mounting rail 81 to monitor the movement state of the clamping mechanism 50 in real time. In another embodiment, each group of detection components 80 has two photoelectric sensors 82, which are respectively disposed at both ends of the mounting rail 81.

[0038] Furthermore, each clamping mechanism 50 includes a mounting plate 51, a limiting plate 52, a pneumatic gripper 53, and a fifth linear guide rail 54; the mounting plate 51 is mounted on the driving end of the first linear guide rail 31; the limiting plate 52 is provided on one side edge of the mounting plate 51 for workpiece mounting; the fifth linear guide rail 54 is provided on the other side of the mounting plate 51; the pneumatic gripper 53 is mounted on the driving end of the fifth linear guide rail 54, so that the fifth linear guide rail 54 can drive the pneumatic gripper 53 to move toward the limiting plate 52, and after the pneumatic gripper 53 moves into position, it can clamp the workpiece mounted on the limiting plate 52.

[0039] Specifically, in one embodiment, the limiting plate 52 is provided with two mounting holes a, each mounting hole a is used for mounting the workpiece; correspondingly, each clamping mechanism 50 includes two pneumatic grippers 53, both pneumatic grippers 53 are mounted on the driving end of the fifth linear guide rail 54 to drive the two pneumatic grippers 53 to move toward the two mounting holes a respectively, thereby realizing the synchronous clamping of the two workpieces.

[0040] Furthermore, each clamping mechanism 50 also includes a dust cover 55, which is mounted on the top side of the mounting plate 51 and one end of it cooperates with the limiting plate 52 to house the pneumatic gripper 53 and the fifth linear guide rail 54 inside the dust cover 55. Thus, the dust generated during the workpiece grinding process can be isolated from the outside of the dust cover 55, thereby preventing the dust from having an adverse effect on the pneumatic gripper 53 and the fifth linear guide rail 54 and other moving mechanisms.

[0041] Furthermore, the workbench 20 is equipped with a control panel 21, which is located on one side surface of the workbench 20. The control panel 21 is electrically connected to the first drive mechanism 30, the second drive mechanism 40, the clamping mechanism 50, and the grinding and polishing mechanism 60, thereby realizing the human-machine interaction function of this grinding and dry polishing equipment 1.

[0042] Furthermore, the bottom of the frame 10 is equipped with several casters 11 to enable the frame 10 to move, thereby enhancing the flexibility of the grinding and dry polishing equipment 1 and its adaptability to multiple nodes in the actual production line.

[0043] In summary, the dry polishing equipment disclosed in this utility model employs the coordinated motion of a first drive mechanism and a second drive mechanism. The first drive mechanism drives the clamping mechanism and the workpiece to reciprocate along a preset direction (such as the X-axis), while the second drive mechanism drives the polishing mechanism to move in a vertical direction (such as the Z-axis) and another horizontal direction (such as the Y-axis). This disperses the overall motion across the workpiece and the polishing mechanism, allowing the polishing mechanism to perform fine position adjustments rather than large-scale movements. This significantly reduces the amplitude of the polishing mechanism's own movement. The reduction in the amplitude of the polishing mechanism's movement directly reduces its acceleration and deceleration changes, thereby reducing vibration caused by inertial forces and effectively reducing mechanical stress. The vibration source; the second drive mechanism adopts a gantry design and is connected to the worktable, providing high rigidity and stability, which can absorb and disperse the vibration energy generated during the grinding process. The dual-axis drive system allows the grinding and polishing mechanism to make smooth and continuous fine-tuning movements, avoiding sudden impacts or jumps. At the same time, the workpiece is driven by the first linear guide rail, and the motion trajectory is preset and smooth, reducing the vibration excitation of the overall system. Thus, through the coordinated movement of the workpiece and the grinding and polishing mechanism, the grinding force is evenly distributed, avoiding local stress concentration and sudden load changes, reducing dynamic instability and resonance phenomena during the grinding process, thereby greatly reducing the noise level during equipment operation.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
