The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] To solve relevant technical problems, such as Figures 1 to 5 As shown, an embodiment of the present invention provides an eccentric swing mechanism for a polishing machine, comprising: A fixed platform 2, on which a support structure 4 is arranged; A mobile platform 1, the mobile platform 1 is arranged on a supporting structure 4, and the mobile platform 1 can swing eccentrically and translate relative to the fixed platform 2 through the supporting structure 4; The eccentricity adjustment structure 10 is provided in two groups and is respectively located on both sides of the mobile platform 1. The eccentricity adjustment structure 10 includes a moving part 101 and a driving part 100. The moving part 101 is connected to the mobile platform 1. The driving part 100 is configured to be driven to drive the moving part 101 and the mobile platform 1 to translate. A driving assembly, which is disposed on the fixed platform 2, and is provided in two groups and corresponds to two groups of eccentricity adjustment structures 10 respectively; The driving assembly includes a main driving member 5, a first driving member 3, a second driving member 13 and a clutch member 14. The first driving member 3 is connected to the mobile platform 1 through the moving part 101, and is used to drive the mobile platform 1 to eccentrically swing under the action of the main driving member 5. The second driving member 13 is used to drive the driving part 100 to move under the action of the main driving member 5. The clutch member 14 has a first linkage state and a second linkage state. In the first linkage state, the main drive member 5 is linked with the first drive member 3, and the main drive member 5 is separated from the second drive member 13; in the second linkage state, the main drive member 5 is linked with the second drive member 13, and the main drive member 5 is separated from the first drive member 3.

[0032] In this embodiment, if Figure 1 and Figure 3 As shown, the fixed platform 2 serves as a fixed base structure and can be fixedly installed on the polishing machine. A support structure 4 is arranged on the upper end of the fixed platform 2, and the mobile platform 1 is installed on the support structure 4. The support structure 4 supports the mobile platform 1, and the mobile platform 1 can swing eccentrically on the support structure 4. In one embodiment, the support structure 4 includes a rotating part that can rotate, and the mobile platform 1 can be placed on the rotating part and clamped by a clamping structure. During the eccentric swing of the mobile platform 1, the rotating part rotates synchronously, so that rolling friction is formed between the rotating part and the mobile platform 1, thereby reducing friction.

[0033] The eccentricity adjustment structure 10 is used to automatically adjust the eccentricity of the mobile platform 1. In other words, the horizontal position of the mobile platform 1 can be adjusted by the eccentricity adjustment structure 10. In this embodiment, the eccentricity adjustment structure 10 is provided in two groups and distributed on both sides of the mobile platform 1. The two groups of eccentricity adjustment structures 10 jointly drive the mobile platform 1 to translate, so as to adjust the eccentricity of the mobile platform 1. In this embodiment, Figure 5 As shown, the eccentricity adjustment structure 10 includes a moving part 101 and a driving part 100 . The moving part 101 is connected to the moving platform 1 . The driving part 100 is configured to be driven to drive the moving part 101 and the moving platform 1 to translate.

[0034] Specifically, in this embodiment, the moving part 101 is a structure directly connected to the moving platform 1. The moving part 101 can at least move linearly back and forth in a single direction to drive the moving platform 1 to translate, and the driving part 100 can drive the moving part 101 to move linearly. In one embodiment, the driving part 100 and the moving part 101 can both output linear motion. For example, the driving part 100 is a slider structure that can move linearly in a vertical direction, and the moving part 101 can move linearly in a horizontal direction. The driving part 100 and the moving part 101 are connected by a connecting rod.

[0035] In another embodiment, the driving part 100 can output rotational motion, and the moving part 101 can output linear motion. For example, the driving part 100 and the moving part 101 form a crank slider structure, or the driving part 100 is a gear assembly, and the moving part 101 is a rack structure, or the driving part 100 is a combination of a gear assembly and a lead screw, and the moving part 101 is a lead screw slider, etc., which are not limited in this embodiment. Preferably, the driving part 100 adopts a structure that can output rotational motion. The reason is that, in this embodiment, the movement of the driving part 100 and the eccentric swing of the mobile platform 1 share a power source, so the power source is a component that can output rotational motion, and when the driving part 100 is a structure that can output rotational motion, it can better adapt to the power source.

[0036] like Figure 2 As shown, the driving assembly is used as a structure for driving the eccentric swing of the mobile platform 1 and driving the driving part 100 and the moving part 101 in the eccentricity adjustment structure 10 to move. In this embodiment, the driving assembly is set in two groups and corresponds to the eccentricity adjustment structure 10 on both sides. The driving assembly is installed on the fixed platform 2, and includes a main driving component 5, a first driving component 3, a second driving component 13 and a clutch component 14. Among them, the main driving component 5 can be driven to output rotational motion, and the first driving component 3 can be installed at the output end of the main driving component 5. Under the action of the main driving components 5 on both sides, the first driving component 3 is driven to rotate, thereby driving the moving part 101 to rotate eccentrically, and then driving the mobile platform 1 to swing eccentrically. One end of the second driving component 13 is connected to the driving part 100 in the eccentricity adjustment structure 10, and the other end can be connected to the output end of the main driving component 5. Under the rotation of the main driving component 5, the driving part 100 is driven to move, and then the moving part 101 is driven to move through the driving part 100, thereby driving the mobile platform 1 to translate to adjust the eccentricity of the mobile platform 1.

[0037] It can be seen that in this embodiment, the main driving member 5 can transmit power to the first driving member 3 to drive the mobile platform 1 to eccentrically swing, and can also transmit power to the moving part 101 of the eccentricity adjustment structure 10 through the second driving member 13 to drive the mobile platform 1 to translate. Obviously, the eccentric swing and translation of the mobile platform 1 cannot be performed at the same time, so it is necessary to adjust the transmission path of the power of the main driving member 5 through the clutch member 14. It is expected that when the eccentricity needs to be adjusted, the main driving member 5 will only transmit power to the second driving member 13, and when the mobile platform 1 needs to eccentrically swing, it will only transmit power to the first driving member 3.

[0038] To this end, in this embodiment, the clutch component 14 has a first linkage state and a second linkage state. In the first linkage state, the main drive component 5 is linked with the first drive component 3, and the main drive component 5 is separated from the second drive component 13; in the second linkage state, the main drive component 5 is linked with the second drive component 13, and the main drive component 5 is separated from the first drive component 3.

[0039] Specifically, in this embodiment, the clutch member 14 is a structure capable of changing the power transmission path, and a similar clutch structure in the related art can be used in application. In a specific implementation, the clutch member 14 can be a structure including a latch or a key, and the power transmission path can be adjusted by disengaging and inserting the latch or key into one of the members, which is not limited in this embodiment.

[0040] On one hand, in the present invention, when the eccentricity of the mobile platform 1 needs to be adjusted, the clutch components 14 on both sides are controlled to be in the second linkage state. At this time, the main driving component 5 can drive the driving part 100 of the eccentricity adjustment structure 10 to move through the second driving component 13, thereby driving the moving part 101 to move linearly and drive the mobile platform 1 to move horizontally to adjust the eccentricity of the mobile platform 1. After the adjustment is in place, the clutch components 14 on both sides are controlled to be in the first linkage state. At this time, the main driving component 5 can drive the mobile platform 1 to swing eccentrically through the first driving component 3, so that the mobile platform 1 performs a polishing movement. It can be seen that this embodiment realizes the technical effect of being able to automatically adjust the eccentricity of the mobile platform 1, making the adjustment process simpler and more convenient, and having a higher adjustment accuracy, thereby solving the problem of the difficulty in adjusting the eccentricity of the swing mechanism of the polishing machine in the related art.

[0041] On the other hand, in this embodiment, the power source for driving the eccentricity adjustment of the mobile platform 1 is the same as the power source for driving the eccentric swing of the mobile platform 1. Different power transmission paths are selected through the clutch component 14 to achieve different purposes, thereby avoiding the high cost caused by the use of multiple power sources and reducing the occupied space of the entire equipment, making the overall structure of the equipment more compact.

[0042] like Figure 5 and Fig. 9 As shown, in one embodiment of the first driving member 3, the first driving member 3 includes a fixed cavity 30; A part of the main driving member 5 is located in the fixed cavity 30, the driving part 100 is arranged in the fixed cavity 30, the upper end of the moving part 101 extends out of the fixed cavity 30 and is connected to the moving platform 1, and the main driving member 5 in the fixed cavity 30 drives the moving platform 1 to swing eccentrically through the moving part 101; The clutch end 141 of the clutch member 14 and the second driving member 13 are disposed in the fixed cavity 30 .

[0043] Specifically, Fig. 9 As shown, in this embodiment, the first driving member 3 includes a bottom plate 34, a side plate 33 and a cover plate 31, wherein the bottom plate 34 is fixed on the fixed platform 2, the side plate 33 is fixed on the bottom plate 34, and the cover plate 31 is fixed on the upper end of the side plate 33. The side plate 33 can be a frame-shaped structure or a circular structure. The bottom plate 34, the side plate 33 and the cover plate 31 can be fixed by welding or screws, etc., and a fixed cavity 30 is formed after being fixed. The upper end of the main driving member 5 extends into the fixed cavity 30 through the bottom plate 34, and the driving part 100 is installed in the fixed cavity 30, specifically, it can be installed on the side plate 33. The lower end of the moving part 101 is transmission-connected with the driving part 100, and the upper end extends out of the fixed cavity 30 through the cover plate 31. Since the moving part 101 needs to move in a straight line, a structure such as a sliding hole 32 for moving the moving part 101 needs to be provided on the cover plate 31. The clutch end 141 of the clutch member 14 and the second driving member 13 are arranged in the fixed cavity 30 , and the power transmission path is controlled by the action of the clutch end 141 .

[0044] After the moving part 101 passes through the fixed cavity 30 and is connected to the fixed platform 2, the first driving member 3 is also connected to the fixed platform 2 through the moving part 101, and the first driving member 3 is eccentric to the moving part 101. Therefore, when the main driving member 5 drives the first driving member 3 to rotate, the first driving member 3 can drive the moving part to rotate eccentrically, thereby driving the moving platform 1 to swing eccentrically through the moving part 101. Under the action of the clutch end 141, the power output by the main driving member 5 can be selectively transmitted to the first driving member 3 and the second driving member 13.

[0045] In one embodiment, the eccentricity adjustment of the mobile platform 1 needs to control the mobile platform 1 to move in the horizontal direction, while the eccentric swing of the mobile platform 1 needs to control the mobile platform 1 to rotate around the vertical axis. Since the eccentricity adjustment and eccentric swing of the mobile platform 1 in the present invention are through the same power source, the rotation axis of the main drive component 5 in this embodiment is perpendicular to the moving direction of the mobile part 101. In other words, the mobile part 101 moves linearly in the horizontal direction, and the rotation axis of the main drive component 5 is a vertical axis. Therefore, when the mobile part 101 is driven to move by the main drive component 5, the rotational motion output by the main drive component 5 needs to be reversed. Specifically, in this embodiment, the drive part 100 includes a first reversing structure, and the second drive component 13 includes a second reversing structure. The first reversing structure cooperates with the second reversing structure to transmit the power of the main drive component 5 to the mobile part 101. In one embodiment, the first reversing structure and the second reversing structure can be a crank slider 11-like structure or a bevel gear structure, etc., and this embodiment does not limit it here.

[0046] In one embodiment, Figure 7 and Figure 8 As shown, the driving part 100 includes a driving screw 1000, and the first reversing structure includes a first bevel gear 1001. The driving screw 1000 is rotatably connected to the fixed cavity 30, and the first bevel gear 1001 is sleeved and fixed on the driving screw 1000; The moving part 101 includes a moving shaft 1010 , a first end of the moving shaft 1010 is threadedly connected to the driving screw 1000 , and a second end of the moving shaft 1010 is connected to the moving platform 1 .

[0047] Specifically, in this embodiment, the driving screw 1000 is horizontally arranged in the fixed cavity 30, and the two ends of the driving screw 1000 can be rotatably connected to the side wall of the fixed cavity 30 through bearings. The first reversing structure is a first bevel gear 1001 sleeved and fixed on the driving screw 1000, and the first bevel gear 1001 can be close to one side wall of the fixed cavity 30, so as to reserve enough moving space for the moving part 101. The moving part 101 includes a vertically arranged moving shaft 1010, the lower end (i.e., the first end) of the moving shaft 1010 is threadedly connected to the driving screw 1000 as a nut, and the upper end (i.e., the second end) of the moving shaft 1010 passes through the fixed cavity 30 and is fixedly connected to the moving platform 1. Specifically, a connecting hole can be opened on the mobile platform 1, and the upper end of the moving shaft 1010 is inserted into the connecting hole and fixed. When the driving screw 1000 is driven to rotate in a fixed axis, the moving shaft 1010 moves along a linear direction on the driving screw 1000, thereby driving the moving platform 1 to translate to adjust the eccentricity of the moving platform 1. In this embodiment, the second reversing structure includes a second bevel gear 130, and the second bevel gear 130 can mesh with the first bevel gear 1001.

[0048] It should be noted that if Figure 8 and Fig. 9 As shown, the second bevel gear 130 can be engaged with and separated from the first bevel gear 1001 under the action of the clutch end 141 of the clutch member 14. When engaged, the main driving member 5 drives the second bevel gear 130 to rotate, and the second bevel gear 130 drives the first bevel gear 1001 to rotate, thereby driving the driving screw 1000 to rotate, and then driving the moving shaft 1010 and the moving platform 1 to translate. When separated, the main driving member 5 drives the fixed cavity 30 to rotate, and the fixed cavity 30 drives the moving platform 1 to eccentrically swing through the moving shaft 1010.

[0049] Since the moving shaft 1010 needs to move linearly under the rotation of the driving screw 1000 when adjusting the eccentricity, the rotation of the moving shaft 1010 needs to be limited, that is, the first driving member 3 needs to be controlled to remain fixed, and the sliding hole 32 on the first driving member 3 serves as a limit structure for the rotation direction of the moving shaft 1010. Figure 5 and Figure 6 As shown, in this embodiment, a fixing mechanism 12 is also included. The fixing mechanism 12 includes a fixing portion 120 and a movable portion 121. The fixing portion 120 is fixed on the fixing platform 2, and the movable portion 121 is configured to be driven to connect to and disconnect from the first driving member 3.

[0050] In addition, it should be noted that after the eccentricity is adjusted, the movable shaft 1010 needs to remain eccentric to the rotation axis of the main driving component 5.

[0051] In this embodiment, the fixing mechanism 12 is used to keep the first drive member 3 fixed when adjusting the eccentricity. The fixing mechanism 12 includes a fixing portion 120 mounted on the fixing platform 2 and a movable portion 121 connected to the fixing portion 120. The end of the movable portion 121 can be connected to the first drive member 3 so that the fixing cavity 30 remains fixed, and can also be separated from the first drive member 3 so that the first drive member 3 can rotate freely. In one embodiment, the movable portion 121 can abut against the first drive member 3 to fix the first drive member 3. In another embodiment, the movable portion 121 can be partially inserted into the first drive member 3 to fix the first drive member 3. In addition, the movable portion 121 can move along a vertical straight line or along a horizontal straight line, or can move in a rotational manner, which is not limited in this embodiment.

[0052] In one embodiment, the movable portion 121 is configured to be movable in a vertical straight line, thereby saving lateral space of the device. Specifically, the movable portion 121 includes a telescopic rod 1210, the upper end of which can extend toward the first driving member 3 and be connected to the first driving member 3, and can be retracted away from the first driving member 3 and disengaged from the first driving member 3.

[0053] In this embodiment, the fixing part 120 may be a cylinder 1400 or a linear motor or a hydraulic cylinder, etc., and the telescopic rod 1210 may be a piston rod, etc. After the fixing part 120 is fixed to the fixing platform 2, it can drive the telescopic rod 1210 to move in a vertical linear direction, thereby connecting and disconnecting with the first driving member 3, so as to fix the first driving member 3 and release the first driving member 3.

[0054] When the upper end of the telescopic rod 1210 fixes the first driving member 3 by abutting against the lower end surface of the first driving member 3, in order to better apply the clamping force and avoid damaging the first driving member 3, in this embodiment, a flexible arc-shaped pressure head 1211 is provided at the upper end of the telescopic rod 1210, and the upper surface of the arc-shaped pressure head 1211 is provided as an arc-shaped surface 1212, and the arc-shaped surface 1212 is used to abut against the lower end surface of the first driving member 3.

[0055] When pressed tightly, the arc-shaped pressing head 1211 generates a certain amount of deformation to absorb the extension of the telescopic rod 1210, and increases the contact area between the arc-shaped pressing head 1211 and the first driving member 3, thereby improving the stability of the connection.

[0056] In the present invention, the main driving member 5 is used to drive the first driving member 3 to rotate or the second driving member 13 to rotate under the action of the clutch member 14. In one embodiment, Figures 7 to 9 As shown, the main driving component 5 includes a driving outer shaft 51 and a driving inner shaft 50. The driving outer shaft 51 is rotatably mounted on the fixed platform 2, and the driving outer shaft 51 is configured to be driven to rotate around a fixed axis. The inner driving shaft 50 is disposed in the outer driving shaft 51. The inner driving shaft 50 and the outer driving shaft 51 are connected via a transmission member 15, so that the outer driving shaft 51 can drive the inner driving shaft 50 to rotate, and the inner driving shaft 50 can move linearly along the axial direction of the inner driving shaft 50. The upper end of the inner driving shaft 50 extends into the fixed cavity 30 and is transmission-connected to the second driving member 13; The clutch member 14 includes a telescopic driving structure 140, and the clutch end 141 of the clutch member 14 includes a first plug-in structure 1412 and a second plug-in structure 1411. The first plug-in structure 1412 is disposed in the fixed cavity 30, and the second plug-in structure 1411 is disposed at the upper end of the inner driving shaft 50. The first plug-in structure 1412 and the second plug-in structure 1411 can be connected and disconnected in a plug-in manner. The telescopic driving structure 140 is used to drive the inner driving shaft 50 to move linearly along the axial direction, so that the first plug-in structure 1412 is connected to and disconnected from the second plug-in structure 1411 .

[0057] Specifically, the driving outer shaft 51 is rotatably mounted on the fixed platform 2 through a bearing in the vertical direction, and the lower end of the driving outer shaft 51 is transmission-connected with the driving motor 9, and the driving outer shaft 51 is driven to rotate in a fixed axis by the driving motor 9. A through mounting hole is axially arranged inside the driving outer shaft 51, and the driving inner shaft 50 is mounted in the mounting hole. The upper end of the driving inner shaft 50 extends out of the driving outer shaft 51 and extends into the fixed cavity 30 to be transmission-connected with the second driving member 13.

[0058] like Fig. 9 As shown, the first plug-in structure 1412 in the clutch member 14 is fixedly installed in the fixed cavity 30, and the second plug-in structure 1411 is fixedly installed at the upper end of the driving inner shaft 50. In this embodiment, the clutch process is the process of the first plug-in structure 1412 and the second plug-in structure 1411 being plugged in and disconnected. Since the second plug-in structure 1411 is installed on the driving inner shaft 50, the driving inner shaft 50 needs to move in an axial straight line during the plug-in cooperation between the second plug-in structure 1411 and the first plug-in structure 1412. To this end, the clutch member 14 in this embodiment also includes a telescopic driving structure 140, which can drive the driving inner shaft 50 to move in an axial straight line in the driving outer shaft 51.

[0059] Since the inner drive shaft 50 also needs to be able to rotate driven by the outer drive shaft 51, the inner drive shaft 50 and the outer drive shaft 51 need to be connected through the transmission member 15, so that the rotation of the outer drive shaft 51 can be transmitted to the inner drive shaft 50. In one embodiment, the transmission member 15 is a spline provided on the inner drive shaft 50 or the outer drive shaft 51, and a slide groove matching the spline is provided on the outer drive shaft 51 or the inner drive shaft 50. During the extension and retraction process of the inner drive shaft 50, the spline slides in the slide groove, and the outer drive shaft 51 drives the inner drive shaft 50 to rotate through the spline.

[0060] During the upward movement of the inner drive shaft 50, the second plug-in structure 1411 gradually disengages from the first plug-in structure 1412, and the second drive member 13 installed at the upper end of the inner drive shaft 50 is connected to the drive unit 100 of the eccentricity adjustment structure 10. At this time, the rotation of the outer drive shaft 51 will drive the inner drive shaft 50 to rotate, and then drive the second drive member 13 and the drive unit 100 to move. During the downward movement of the inner drive shaft 50, the second plug-in structure 1411 is plugged with the first plug-in structure 1412, and the second drive member 13 is disengaged from the drive unit 100. At this time, the rotation of the outer drive shaft 51 will drive the inner drive shaft 50 to rotate, and then drive the first drive member 3 to rotate through the first plug-in structure 1412 and the second plug-in structure 1411.

[0061] When the second driving member 13 is the second bevel gear 130 and the driving part 100 is the first bevel gear 1001 , the above-mentioned clutching process is a process of meshing and disengaging the first bevel gear 1001 and the second bevel gear 130 .

[0062] In one embodiment of the clutch end 141 of the clutch member 14, as Fig. 9 As shown, the clutch end 141 further includes a clutch disk 1410 , the clutch disk 1410 is fixed to the upper end of the inner driving shaft 50 , and the second plug-in structure 1411 is disposed on the clutch disk 1410 .

[0063] Specifically, the clutch disk 1410 can be sleeved and fixed on the upper end of the inner drive shaft 50, and the lower end surface of the clutch disk 1410 can be provided with a second plug structure 1411. A boss can be formed on the upper surface of the bottom plate 34 of the first driving member 3, and the upper end of the inner drive shaft 50 extends out of the boss, and the first plug structure 1412 is provided at the upper end of the boss. In a specific embodiment, the first plug structure 1412 is a plug hole, and the plug holes are provided in a plurality and distributed along the circumferential direction; the second plug structure 1411 is provided as a plug pin, and the plug pin corresponds to the plug hole and is plugged and matched with the plug hole.

[0064] It is understandable that the first plug structure 1412 can also be set as a plug pin, and similarly, the second plug structure 1411 can also be set as a plug hole. In this embodiment, the plug holes are evenly distributed along the circumference of the boss. In the process of adjusting the eccentricity, it is necessary to detect the rotation angle of the driving inner shaft 50. The rotation angle of the driving inner shaft 50 determines the adjustment value of the eccentricity. When the driving inner shaft 50 stops rotating, the plug pin needs to be able to correspond to the plug hole up and down. In other words, the adjustment process of the eccentricity in this embodiment is a step-by-step adjustment.

[0065] Since the inner drive shaft 50 needs to be driven by the telescopic drive structure 140 to move in an axial straight line, as shown in FIG. Figure 8As shown, in one embodiment, the telescopic driving structure 140 includes a cylinder 1400 fixedly mounted at the lower end of the driving outer shaft 51, a piston is arranged in the cylinder 1400, and the piston is fixedly connected to the lower end of the driving inner shaft 50; a rotary joint 1401 for air inlet and outlet is arranged at the lower end of the cylinder 1400. The driving inner shaft 50 is controlled to move in an axial straight line by the cylinder 1400, and during the rotation of the driving inner shaft 50, the cylinder 1400 can rotate synchronously due to the rotary joint 1401.

[0066] In another embodiment, the cylinder 1400 may be fixed on the fixed platform 2, and the piston rod of the cylinder 1400 may be connected to the driving inner shaft 50 via a rotary joint 1401, and the cylinder 1400 remains fixed during the rotation of the driving inner shaft 50.

[0067] Of course, in this embodiment, the telescopic driving structure 140 can also adopt a linear motor or a hydraulic cylinder, etc.

[0068] For the support of the mobile platform 1, Figure 1 As shown, the present invention is implemented by setting a support structure 4 on the fixed platform 2. In one embodiment, in order to better support the movement of the mobile platform 1, the support structure 4 is set in four groups and distributed at the four corners of the fixed platform 2. The support structure 4 can adopt a hard rail sliding structure, but it needs frequent oiling before it can be used. Excessive oiling will lead to the accumulation of lubricating oil, which will affect the use and environment.

[0069] Therefore, in the present invention, if Figure 4 As shown, the support structure 4 is preferably a rolling support structure 4. Specifically, a universal rolling ball bearing 40 is provided in the support structure 4, and four sliding blocks are provided at the lower end of the mobile platform 1, and the sliding blocks are connected to the corresponding universal rolling ball bearings 40. After the rolling ball bearings are provided, the mobile platform 1 has rolling friction during the movement, the friction force is small, the movement is smoother, and the support structure 4 needs to be frequently oiled during the movement.

[0070] Since the driving outer shaft 51 needs to be driven by the driving motor 9 to rotate, Figure 2 As shown, in this embodiment, a driving motor 9 is arranged on the fixed platform 2, a driving wheel 8 is arranged at the output end of the driving motor 9, a driven wheel 7 is fixedly arranged on the driving outer shaft 51, and the driving wheel 8 is transmission-connected with the driven wheel 7.

[0071] It should be noted that in this embodiment, a driving outer shaft 51 is provided on both sides of the fixed platform 2, and the driving motor 9 is arranged between the two driving outer shafts 51. The driving wheel 8 of the driving motor 9 is connected to the passive wheels 7 on both sides through a belt or chain, and the driving motor 9 drives the driving wheel 8 and the passive wheel 7 to rotate in the same direction.

[0072] Since the rotation angle of the driving outer shaft 51 determines the rotation angle of the driving inner shaft 50, and thus determines the adjustment value of the eccentricity, in order to accurately monitor the adjustment value of the eccentricity, such as Figure 2 As shown, this embodiment also includes an angle information monitoring component 6, which is used to monitor the rotation angle of the driving outer shaft 51. In one embodiment, the angle information monitoring component 6 can be an encoder or an angle sensor connected to the driving outer shaft 51.

[0073] In addition, in one embodiment, Figure 5 As shown, the first drive member 3 is eccentrically arranged with the main drive member 5, and the fixing mechanism 12 arranged on one side of the main drive member 5 needs to be pressed against the lower end of the first drive member 3 by the arc-shaped pressure head 1211 to adjust the eccentricity, so the lower end of the first drive member 3 needs to have an area corresponding to the arc-shaped pressure head 1211. Since the first drive member 3 is eccentrically arranged with the main drive member 5, in a relatively compact structure, when the first drive member 3 is driven to rotate to a certain angle, it cannot correspond to the arc-shaped pressure head 1211, resulting in the arc-shaped pressure head 1211 being unable to fix the first drive member 3. For this reason, in this embodiment, a position detection sensor 16 is also provided on the fixed platform 2 to detect the position of the first drive member 3, so as to ensure that before the eccentricity is adjusted, the first drive member 3 is located at a position where it can be pressed against by the arc-shaped pressure head 1211. If it is not located, the first drive member 3 should be controlled to rotate to the corresponding position before the eccentricity is adjusted.

[0074] According to another aspect of the present invention, a polishing machine is provided, comprising the above-mentioned eccentric swing mechanism of the polishing machine.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Within the spirit and principle of the present invention, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present invention.
