Description

Technical Field

[0001] This application relates to the field of glass processing technology, and more specifically, to a polishing apparatus and polishing equipment. Background Technology

[0002] To achieve the required appearance and surface quality of glass products, grinding and polishing processes are frequently used for finishing. The purpose of grinding and polishing is to obtain the desired shape and surface quality. For circular curved glass products, to better polish the surface, current polishing machines on the market use multi-axis robotic arms (such as five-axis polishing machines) or machine tools to adjust the angle of the polishing head relative to the glass surface, allowing the polishing head to better conform to the curved glass surface. When polishing circular curved glass surfaces with different curvatures, programmers need to create operating programs to readjust the angle of the robotic arm or machine tool relative to the glass surface for better conformation. Therefore, adjusting the polishing head oscillation angle of existing polishing machines is cumbersome, requires a significant workload for programmers, and results in a complex overall structure, making maintenance and use difficult.

[0025] Furthermore, the position adjustment component includes:

[0026] A connecting rod is mounted on the mounting plate, and the axial direction of the connecting rod is parallel to the axial direction of the first through hole;

[0027] The slider is sleeved on the connecting rod and has a sliding state that allows it to slide relative to the connecting rod and a stationary state that is stationary relative to the connecting rod along the axial direction of the connecting rod.

[0028] A locking element is connected to the second end and can lock the slider to the stationary state or unlock it to the sliding state.

[0029] Furthermore, a groove is provided on the side of the mounting plate near the mounting component. The groove is recessed in a direction away from the mounting component. In addition, along the radial direction of the first through hole, the groove extends in a direction away from the first through hole and penetrates the outer peripheral surface of the mounting plate. The connecting rod is installed in the groove and the slider is clearance-fitted with the inner sidewall of the groove.

[0030] Furthermore, the mounting component includes:

[0038] On the other hand, this application also provides a polishing apparatus, characterized in that it comprises:

[0039] Motion control device;

[0040] The polishing device is connected to the motion control device.

[0041] In this application, the polishing apparatus includes a polishing mechanism and an angle adjustment mechanism. The driver of the polishing mechanism is mounted on a mounting component, and the drive shaft is connected to the driver and can rotate around its own axis under the drive of the driver. The angle adjustment mechanism includes a universal joint and a resilient reset assembly. The universal joint connects the polishing component and the drive shaft. Simultaneously, the resilient reset assembly is connected to the mounting component and rotatably connected to the polishing component, so that the resilient reset assembly can reset the polishing component without affecting its rotation. Specifically, the resilient reset assembly can reciprocate between a first state and a second state under its own elastic force. The polishing component has a first position where the angle between it and the drive shaft is greater than zero degrees, and a second position where the angle between it and the drive shaft is equal to zero degrees. The first position is the position of the polishing component after rotating relative to the drive shaft to better conform to the surface of the circular curved glass. The second position is the initial position of the polishing component. In the second position, the polishing component can polish flat glass products or the top area of ​​circular curved glass products.

[0042] When the drive shaft rotates the polishing component to polish the circular curved glass product, the polishing component can rotate relative to the drive shaft in any direction under the action of the universal joint. When polishing different curvature positions of the circular curved glass, the polishing component can adaptively adjust its angle relative to the surface of the circular curved glass, thus rotating from the second position to the first position. This ensures that the polishing component can better conform to the surface of the circular curved glass, eliminating the need for manual programming and additional drive mechanisms to adjust the swing angle of the polishing component. Simultaneously, during the rotation of the polishing component from the second position to the first position, the elastic reset component deforms from the first state to the second state, ensuring that the polishing component can adaptively adjust its angle relative to the drive shaft in real time to better conform to the surface of the circular curved glass. When the polishing component does not need to rotate to the first position, such as when polishing the top of the circular curved glass or after polishing, or when polishing a flat glass product, the elastic reset component will tend to return from the second state to the first state under its own elasticity. Therefore, during the process of the elastic reset component returning from the second state to the first state, it drives the polishing component back to the second position. Therefore, when the polishing component returns to the second position, it can be brought back by the elastic reset component. There is no need for an additional drive source or manual programming to drive the polishing component back to its original position, which greatly reduces the overall structural complexity of the polishing device, making the polishing device easier to maintain, and it is easy to use with low technical requirements for operators.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0057] To address the issues of cumbersome adjustment of the polishing head's oscillation angle in polishing machines and the heavy workload for programmers, the first embodiment of this invention provides a polishing device, which includes a polishing mechanism and an angle adjustment mechanism. Please refer to... Figures 1 to 8 The polishing mechanism includes a polishing component 10, a mounting component 20, a driver 30, and a drive shaft 40. The driver 30 is mounted on the mounting component 20, and the drive shaft 40 is connected to the driver 30 and can rotate around its own axis under the drive of the driver 30. The polishing device can be mounted on a motion control device via the mounting component 20. The motion control device may specifically include either a robotic arm or a machine tool. When mounted on a machine tool, the mounting component 20 of the polishing device can be connected to the Z-axis of the machine tool.

[0058] like Figures 1 to 3As shown, the angle adjustment mechanism includes a universal joint 50 and a flexible reset assembly 60. The universal joint 50 is connected between the polishing component 10 and the drive shaft 40. The universal joint 50 allows rotational motion to be transmitted between the drive shaft 40 and the polishing component 10 while allowing the polishing component 10 and the drive shaft 40 to have different relative positions. Therefore, during the rotation of the polishing component 10 driven by the drive shaft 40, the polishing component 10 can rotate relative to the drive shaft 40 in any direction under the action of the universal joint 50. This allows the polishing component 10 to adaptively adjust its angle relative to the circular curved glass 70 as the curvature of the circular curved glass 70 changes during the polishing process, thereby better conforming to the surface of the circular curved glass 70 and improving the polishing quality. There is no need for manual programming or other drive sources to adjust the angle of the polishing component 10 relative to the drive shaft 40. The flexible reset assembly 60 is connected to the mounting component 20 and rotatably connected to the polishing component 10, so that the flexible reset assembly 60 can pull the polishing component 10 back to its original position without interfering with the rotational motion of the polishing component 10. Furthermore, the elastic reset component 60 can repeatedly switch between the first state and the second state under its own elastic force.

[0059] The polishing component 10 has a first position where the angle between it and the drive shaft 40 is greater than zero degrees, and a second position where the angle between it and the drive shaft 40 is equal to zero degrees. During the rotation from the second position to the first position, the polishing component 10 causes the elastic reset component 60 to deform from the first state to the second state. During the return of the elastic reset component 60 from the second state to the first state, the polishing component 10 returns to the second position. Therefore, during the polishing of the circular curved glass 70, this embodiment, through the universal joint 50, ensures that the polishing component 10 can adaptively adjust its swing angle relative to the drive shaft 40, thereby better conforming to the different curvatures of the circular curved glass 70 surface. Furthermore, the elastic reset component 60 not only works with the universal joint 50 to allow the polishing component 10 to adjust its swing angle in real time, but also ensures that the polishing component 10 returns to the second position through its own elastic deformation. This not only reduces the workload of programmers and the difficulty of adjusting the swing angle of the polishing component 10, but also reduces the structural complexity and design cost of the polishing equipment using this polishing device. When the polishing device is installed on a machine tool, the three-axis machine tool can process the circular curved glass 70, reducing the structural complexity of the polishing equipment and reducing the production and use costs of the polishing equipment.

[0060] As can be seen, in this embodiment, the polishing device includes a polishing mechanism and an angle adjustment mechanism. The driver 30 of the polishing mechanism is mounted on the mounting component 20, and the transmission shaft 40 is connected to the driver 30 and can rotate around its own axis under the drive of the driver 30. The angle adjustment mechanism includes a universal joint 50 and an elastic reset component 60. The universal joint 50 is connected between the polishing component 10 and the transmission shaft 40. Simultaneously, the elastic reset component 60 is connected to the mounting component 20 and rotatably connected to the polishing component 10, so that the elastic reset component 60 can reset the polishing component 10 without affecting its rotation. Specifically, the elastic reset component 60 can reciprocate between a first state and a second state under its own elastic force. The polishing component 10 has a first position where the angle between it and the drive shaft 40 is greater than zero degrees and a second position where the angle between it and the drive shaft 40 is equal to zero degrees. The first position is the position after the polishing component 10 rotates relative to the drive shaft 40 in order to better fit the surface of the circular curved glass 70. The second position is the initial position of the polishing component 10. In the second position, the polishing component 10 can polish the flat glass product or the top area of ​​the circular curved glass 70 product.

[0061] When the drive shaft 40 drives the polishing component 10 to rotate and polish the circular curved glass 70, the polishing component 10 can rotate relative to the drive shaft 40 in any direction under the action of the universal joint 50. When polishing different curvature positions of the circular curved glass 70, the polishing component 10 can adaptively adjust its angle relative to the surface of the circular curved glass 70, thus rotating from the second position to the first position. This ensures that the polishing component 10 can better conform to the surface of the circular curved glass 70, eliminating the need for manual programming and additional actuators 30 to adjust the swing angle of the polishing component 10. Simultaneously, during the rotation from the second position to the first position, the polishing component 10 causes the elastic reset component 60 to deform from the first state to the second state, ensuring that the polishing component 10 can adaptively adjust its angle relative to the drive shaft 40 in real time to better conform to the surface of the circular curved glass 70. When the polishing component 10 does not need to rotate to the first position, such as when polishing the top of the circular curved glass 70 or after polishing, or when polishing a flat glass product, the elastic reset component 60 will tend to return from the second state to the first state under its own elasticity. Therefore, during the process of the elastic reset component 60 returning from the second state to the first state, it drives the polishing component 10 back to the second position. Thus, when the polishing component 10 returns to the second position, it can be brought back by the elastic reset component 60, without the need for an additional drive source or manual programming to drive the polishing component 10 back to its original position. This greatly reduces the overall structural complexity of the polishing device, making the polishing device easier to maintain, and with lower operating difficulty and lower technical requirements for operators.

[0062] like Figure 2 and Figure 6 As shown, the universal joint in this embodiment includes a first connecting portion 51, a second connecting portion 52, and an adapter portion 53. The first connecting portion 51 is connected to the drive shaft 40. The second connecting portion 52 is connected to the polishing component 10. The adapter portion 53 is rotatably connected between the first connecting portion 51 and the second connecting portion 52, allowing the second connecting portion 52 to rotate relative to the first connecting portion 51 along a first direction and a second direction that are perpendicular to each other. The first direction is... Figure 1 and Figure 5 The direction indicated by the middle arrow X, the second direction is Figure 1 and Figure 4 The direction indicated by the middle arrow Y. Therefore, before the drive shaft 40 is started to rotate by the driver 30, the polishing component 10 can rotate relative to the drive shaft 40 along the first and second directions. During the process of the drive shaft 40 being started by the driver 30 to drive the polishing component 10 to rotate around the axis of the drive shaft 40, the polishing component 10 can rotate relative to the drive shaft 40 in any direction, thereby adaptively adjusting its own swing angle relative to the drive shaft 40 to better conform to different curvature positions on the surface of the circular curved glass 70. This universal joint 50 has low structural complexity and is simple and convenient to assemble with the drive shaft 40 and the polishing component 10.

[0063] The type of universal joint 50 in this embodiment may include one of the following: a cross-type universal joint, a double universal joint, or a ball-cage universal joint. A cross-type universal joint consists of two fork-shaped members rotatably connected by a cross shaft with four bearings. It allows rotational motion to be transmitted between two axes at a certain angle. A double universal joint consists of two universal joints 50 and an intermediate shaft, ensuring near-constant speed transmission even at large angles. A ball-cage universal joint consists of an inner ring, an outer ring, several steel balls, and a cage that holds these steel balls in place. It can withstand large angular offsets and provides constant speed transmission.

[0064] In this embodiment, the universal joint 50 is preferably a cross-shaped universal joint. Cross-shaped universal joints have a relatively simple structure and low cost, facilitating regular inspection and replacement of worn parts, and ensuring the long-term stable operation of the polishing device. Specifically, the first connecting part 51 and the second connecting part 52 are fork-shaped components of the cross-shaped universal joint, and the adapter part 53 is a cross shaft. The cross shaft has two mutually perpendicular axes; the first direction is parallel to one of the axes, and the second direction is parallel to the other axis. U-shaped grooves are provided at the ends of the first connecting part 51 and the second connecting part 52 closest to each other. Two ends of the cross shaft are rotatably mounted in the U-shaped groove of the first connecting part 51, and the other two ends are rotatably mounted in the U-shaped groove of the second connecting part 52. This allows the second connecting part 52 to rotate relative to the first connecting part 51 along the mutually perpendicular first and second directions, facilitating assembly, disassembly, and maintenance.

[0065] like Figure 5 As shown, the mounting component 20 of the polishing device has a mounting cavity 201. The driver 30 is mounted in the mounting cavity 201. The drive shaft 40 includes a first shaft segment 41 and a second shaft segment 42. The first shaft segment 41 is connected to the driver 30 and can rotate around its own axis under the drive of the driver 30. The end of the first shaft segment 41 away from the driver 30 extends outside the mounting cavity 201. The second shaft segment 42 is connected to the end of the first shaft segment 41 located outside the mounting cavity 201 and is coaxially arranged with the first shaft segment 41. The end of the second shaft segment 42 away from the first shaft segment 41 is connected to the first connecting part 51. In this embodiment, by mounting the driver 30 in the mounting cavity 201 and connecting the driver 30 and the second shaft segment 42 through the first shaft segment 41, the protective performance of the mounting component 20 for the driver 30 can be improved, and the overall structure of the polishing device can be made more stable and reliable. At the same time, in this embodiment, the second shaft segment 42 can be connected to the first connecting part 51 of the universal joint 50 firstly, and the polishing component 10 and the elastic reset component 60 can be connected before the mounted components are connected. Figure 2 The overall structure shown is connected to the first shaft section 41 via the second shaft section 42, which can greatly improve the assembly convenience and efficiency of the polishing device, facilitate the modular production of the polishing device, and improve production efficiency.

[0066] Combination Figure 1 as well as Figures 4 to 6As can be seen, the elastic reset assembly 60 in this embodiment includes a connecting component 61 and a tension spring 62. The connecting component 61 is rotatably connected to the polishing component 10. Along the stretching direction of the tension spring 62, one end of the tension spring 62 is connected to the mounting component 20 and the other end is connected to the connecting component 61. When the elastic reset assembly 60 is in the first state, the stretching length of the tension spring 62 is different from that in the second state, thereby realizing the transformation of the elastic reset assembly 60 between the first and second states when the stretching length of the tension spring 62 is at different values. During the rotation of the polishing component 10 with the drive shaft 40, since the connecting component 61 is rotatable relative to the polishing component 10, it can be ensured that the tension spring 62 will not become entangled as the polishing component 10 rotates or twists. Furthermore, the tension spring 62 is radially offset between the drive shaft 40 and the universal joint 50 to ensure that the tension spring 62 will not interfere with the drive shaft 40 and the universal joint 50. When the polishing component 10 is in the first position, the length by which the tension spring 62 is stretched by the connecting component 61 is different from the length by which the polishing component 10 is stretched when it is in the second position.

[0067] During the rotation of the polishing component 10 from the second position to the first position, the polishing component 10 can drive the connecting component 61 to pull the tension spring 62 to produce tensile deformation. When the polishing component 10 does not need to process the curved surface of the corresponding curvature, the tension spring 62 pulls the polishing component 10 connected to the connecting component 61 back to the second position under its own elastic force. The reset of the polishing component 10 can be achieved without additional drive source and programming operation.

[0068] Therefore, in this embodiment, the connection between the tension spring 62 and the connecting component 61 not only ensures that the polishing component 10 can swing relative to the drive shaft 40, but also allows the polishing component 10 to return to the second position under the tension of the tension spring 62.

[0069] Specifically, in some embodiments, the tension springs 62 may include at least three springs arranged circumferentially along the drive shaft 40, with equal spacing between adjacent springs 62. Thus, in this embodiment, the polishing component 10, rotatably connected to the connecting member 61, can be rotated relative to the drive shaft 40 using at least three equally spaced tension springs 62, thereby pulling the polishing component 10 back to the second position. When the polishing component 10 adaptively adjusts its swing angle relative to the drive shaft 40 according to the curvature of the circular curved glass 70 surface, the polishing component 10 can drive the connecting member 61 to deform the at least three tension springs 62, thereby swinging to the first position. When the polishing component 10 is in the first position, the extension length of at least one tension spring 62 is less than the extension length of at least two other tension springs 62. Moreover, in the first position, the force generated by the at least three tension springs 62 ensures that the polishing component 10 can apply greater pressure to the circular curved glass 70, thereby ensuring the polishing effect. When the polishing component 10 is in the second position, at least three tension springs 62, spaced at equal intervals, ensure that the polishing component 10 is more stably positioned in the second position. This ensures that the reset polishing component 10 is aligned with the drive shaft 40 along the same axis, improving the polishing effect on flat glass products or the top of curved glass when the polishing component 10 is in the second position. The number of tension springs 62 may specifically include three, four, five, or six, or other values ​​not less than three. The specific number can be flexibly adjusted according to requirements, and this embodiment does not impose a unique limitation.

[0070] In this embodiment, the polishing component 10 includes a connecting shaft 11 and a polishing disc 12. The polishing disc 12 is disposed at one end of the connecting shaft 11. The connecting component 61 includes a mounting disc 611 and a first bearing 612. When the polishing component 10 is in the second position, the angle between the axis of the connecting shaft 11 and the axis of the transmission shaft 40 is zero degrees, that is, their axes coincide or are coaxial. In the first position, the angle between the axis of the connecting shaft 11 and the axis of the transmission shaft 40 is greater than zero degrees. Figure 3 and Figure 6 It is known that a first through hole 111 is provided in the mounting plate 611, and the end of the tension spring 62 away from the mounting component 20 is connected to the mounting plate 611. The first bearing 612 is sleeved on the end of the connecting shaft 11 away from the polishing plate 12 and fixed in the first through hole 111. The end of the connecting shaft 11 away from the polishing plate 12 extends at least partially to the end of the mounting plate 611 near the universal joint 50 and is connected to the universal joint 50. Thus, in this embodiment, by installing the first bearing 612 in the first through hole 111 of the mounting plate 611, the connecting shaft 11 of the mounting plate 611 and the polishing component 10 is rotatably connected. The assembly difficulty is low, and it can ensure that after the tension spring 62 is connected to the mounting plate 611, the tension spring 62 will not twist or entangle during the rotation of the connecting shaft 11, thereby improving the reliability and stability of the entire device.

[0071] Specifically, such as Figure 3 As shown, a boss 113 can be provided on the inner wall of the first through hole 111 along the radial direction of the first through hole 111. After the first bearing 612 is placed on the side of the boss 113 near the universal joint 50, the connecting shaft 11 passes through the inner hole of the first bearing 612 and connects with the inner wall of the first bearing 612. A first groove 115 is also provided on the inner wall of the first through hole 111. The first groove 115 is located on the side of the boss 113 near the universal joint 50 and is spaced apart from the boss 113. Along the axial direction of the first through hole 111, the first retaining ring 114 is engaged with the first groove 115 to restrict the first bearing 612 between the first retaining ring 114 and the boss 113, making assembly efficient and convenient. In this embodiment, the connecting shaft 11 of the polishing component 10 is also provided with a second groove 110. The second groove 110 is located on the side of the first bearing 612 near the universal joint 50, and a second retaining ring 116 is engaged in the second groove 110. The second retaining ring 116 abuts against the end of the inner ring of the first bearing 612, thereby improving the stability of the first bearing 612 within the first through hole 111.

[0072] In this embodiment, the tension spring 62 includes a first end and a second end disposed opposite to each other. The first end is connected to the mounting component 20. The elastic reset assembly 60 also includes a position adjustment component 63. The position adjustment component 63 is mounted on the mounting plate 611. The position adjustment component 63 includes at least three components, and each of the at least three position adjustment components 63 is connected to the second end of at least three tension springs 62 in a one-to-one correspondence. Along the axial direction of the first through hole 111, the position adjustment component 63 is used to adjust the position of the second end on the mounting plate 611. Thus, by moving the second end of the tension spring 62 closer to or further away from its first end, the length of the tension spring 62 being stretched is adjusted.

[0073] Therefore, after at least three different tension springs 62 are installed between the mounting plate 611 and the mounting component 20, if the tension generated by each tension spring 62 is inconsistent due to assembly errors, manufacturing errors, or differences in the manufacturing materials of the different tension springs 62, resulting in misalignment of the polishing disc 12 after resetting (i.e., the axis of the polishing disc 12 and the connecting shaft 11 does not coincide with the axis of the transmission shaft 40), this embodiment can adjust the position of the second end of the different tension springs 62 on the mounting plate 611 by adjusting the position adjustment component 63 along the axial direction of the first through hole 111, thereby adjusting the length of the tension of the different tension springs 62 until the tension generated by the different tension springs 62 is consistent. Therefore, when the polishing disc 12 is pulled back to the second position by at least three tension springs 62, the polishing disc 12 can be aligned with the axis of the connecting shaft 11 and the axis of the transmission shaft 40, improving the resetting accuracy of the polishing component 10. The tension of the corresponding tension spring 62 can also be increased and adjusted by adjusting the position of the adjustment component 63 at the same time, so as to adjust the overall reset force of the angle adjustment mechanism, ensuring that the reset force of the angle adjustment mechanism can guarantee that the polishing pressure of the polishing disc 12 on the glass reaches the expected pressure, and improve the polishing effect.

[0074] like Figure 3 and Figure 6As shown, the position adjustment component 63 in this embodiment includes a connecting rod 631, a slider 632, and a locking member 633. The connecting rod 631 is mounted on the mounting plate 611, and the axial direction of the connecting rod 631 is parallel to the axial direction of the first through hole 111. The slider 632 is sleeved on the connecting rod 631, and along the axial direction of the connecting rod 631, the slider 632 has a sliding state that can slide relative to the connecting rod 631 and a stationary state that is stationary relative to the connecting rod 631. The locking member 633 is connected to the second end of the tension spring 62 and can lock the slider 632 to the stationary state or unlock it to the sliding state. Therefore, in this embodiment, when it is necessary to adjust the distance between the second end of the tension spring 62 and the first end to adjust the tension length of the tension spring 62, it is only necessary to slide the slider 632 along the axial direction of the connecting rod 631 to a position that allows the second end to be closer to or farther from the first end when the slider 632 is in a sliding state that can slide relative to the connecting rod 631. Then, the slider 632 can be locked in the current position by the locking member 633 connected to the second end of the tension spring 62. The position adjustment method is convenient and quick. Therefore, in this embodiment, the slider 632 is slidably connected to the connecting rod 631, and the end ring of the second end of the tension spring 62 is sleeved on the locking member 633. By sliding the slider 632 up and down along the axial direction of the connecting rod 631, the upper and lower positions of the slider 632 on the connecting rod 631 are controlled by the locking member 633 (specifically the screw mentioned below), thereby adjusting the length of the extension of the tension spring 62 until the tension force generated by each tension spring 62 is equal. Thus, when the polishing component 10 is reset to the second position, the polishing disk 12 can be aligned with the axis of the connecting shaft 11 and the transmission shaft 40. Furthermore, the sliders 632 of at least three position adjustment components 63 (such as three position adjustment components 63) can be slid simultaneously, increasing the tension of each tension spring 62, thereby simultaneously increasing the reset force of the angle adjustment mechanism. This is because insufficient reset force may lead to insufficient pressure of the polishing disk 12 on the glass, affecting the polishing effect.

[0075] Specifically, such as Figure 3As shown, in this embodiment, the slider 632 is provided with a first mounting hole 321 and a second mounting hole 322. The first mounting hole 321 is adapted to the connecting rod 631, and the connecting rod 631 is sleeved in the first mounting hole 321 and has a clearance fit with the first mounting hole 321, so that the slider 632 can slide relative to the connecting rod 631. The second mounting hole 322 communicates with the first mounting hole 321 and is provided through the slider 632 on one side of the connecting rod 631 radially. In this embodiment, the locking member 633 may specifically include a screw, and the inner wall surface of the second mounting hole 322 is provided with a threaded hole adapted to the threaded section of the screw. The second end of the tension spring 62 can specifically be an end ring structure. After the end ring structure is fitted onto the screw, at least part of the screw's threaded section is pre-installed in the second mounting hole 322. When the slider 632 drives the screw and the end ring of the second end of the tension spring 62 fitted onto the screw to a predetermined position on the connecting rod 631, the screw is screwed along the second mounting hole 322 until it is fixedly connected to the connecting rod 631. This fixes the second end of the tension spring 62 to the predetermined position on the connecting rod 631, completing the adjustment of the tension length of the tension spring 62, and thus completing the adjustment of the tension force of the tension spring 62. During this process, since the screw always remains connected to the slider 632, the second end of the tension spring 62 remains stably connected to the screw, ensuring that the locking part 633 does not need to be reconnected to the slider 632 for each adjustment. This prevents components from falling off and makes the adjustment method more convenient and reliable.

[0076] In this embodiment, a groove 112 is provided on the side of the mounting plate 611 near the mounting component 20, and the groove 112 is recessed in a direction away from the mounting component 20. Furthermore, along the radial direction of the first through hole 111, the groove 112 extends away from the first through hole 111 and penetrates the outer peripheral surface of the mounting plate 611, so that the groove 112 forms a groove structure with one opening facing the mounting component 20 and the other opening located on the outer periphery of the groove 112 along the radial direction away from the first through hole 111. The connecting rod 631 is installed in the groove 112, and the slider 632 is clearance-fitted with the inner sidewall of the groove 112. Therefore, by installing the connecting rod 631 in the groove 112 in this embodiment, the structural compactness of the assembled mounting plate 611 and position adjustment component 63 can be improved, thereby improving the protective performance of the position adjustment component 63 and preventing the position adjustment component 63 from being exposed to the outside and thus reducing its structural strength. Meanwhile, since the groove 112 has two openings, it not only facilitates the installation of the connecting rod 631, but also ensures that the operator can slide the slider 632 from the opening on the outer periphery of the groove 112 to adjust the vertical position of the slider 632. This improves the structural compactness and strength between the position adjustment component 63 and the mounting plate 611, while also improving the convenience of adjusting the position of the slider 632.

[0077] Please see Figures 4 to 7In this embodiment, the mounting component 20 may specifically include a housing 21, a flange 22, and an end cap 23. A second through hole 211 is provided within the housing 21. Along the axial direction of the second through hole 211, the flange 22 is mounted on one end of the housing 21 and covers the opening of the second through hole 211. Along the axial direction of the second through hole 211, the end cap 23 covers the opening of the second through hole 211 away from the flange 22 and, together with the inner wall of the second through hole 211 and the flange 22, forms a mounting cavity 201. A third through hole 231 communicating with the mounting cavity 201 is provided within the end cap 23. The driver 30 is mounted within the mounting cavity 201 to improve the protection performance of the driver 30 and the compactness and reliability of the entire device. A drive shaft 40 is connected to the driver 30, and at least part of the drive shaft 40 extends along the third through hole 231 to the outside of the mounting cavity 201 and connects to the universal joint 50. The end of the tension spring 62 away from the connecting component 61 is connected to the end cover 23. Specifically, multiple bolts or screws can be spaced at intervals on the outer circumferential surface of the end cover 23 corresponding to at least three tension springs 62, and the first end of the tension spring 62 can be fixedly connected to the bolts or screws. When the first end is also an end ring structure, the end ring can be fitted onto the bolts or screws. The polishing device obtained by connecting the mounting component 20 with the universal joint 50, the elastic reset component 60 and the polishing component 10 in this embodiment is not only compact and reliable in overall structure, but can also be adaptively connected to the Z-axis of the robotic arm or machine tool through the flange 22, which is convenient and can improve the flexibility of the polishing device in use.

[0078] like Figure 4 As shown, the driver 30 in this embodiment includes a motor 31, which includes an output shaft 311. The mounting component 20 also includes a mounting base 24, a mounting post 25, and a second bearing 26. The mounting base 24 is installed on the bottom of the mounting cavity 201 near the end cover 23. A fourth through hole 241 is provided in the mounting base 24. The motor 31 is mounted on the mounting base 24 and located between the mounting base 24 and the flange 22. The output shaft 311 is located on the side of the motor 31 near the mounting base 24 and passes through the fourth through hole 241. The portion of the drive shaft 40 located in the mounting cavity 201 passes through the fourth through hole 241 and is connected to the output shaft 311. The mounting post 25 is located between the motor 31 and the inner wall of the mounting cavity 201, and the opposite ends of the mounting post 25 are fixedly connected to the mounting base 24 and the flange 22, respectively. This facilitates assembly and improves the stability and reliability between the flange 22 and the mounting component 20. Mounting posts 25 may include at least three (such as three, four, five, etc.), and at least three mounting posts 25 are spaced apart along the circumference of the output shaft 311 and connected between the mounting base 24 and the flange 22, thereby further improving the stability and reliability of the overall structure of the mounting component 20.

[0079] The second bearing 26 includes at least two bearings, which are installed within the fourth through hole 241 and sleeved on the outer periphery of the drive shaft 40, thereby improving the stability of the drive shaft 40 during rotation. Figure 7 As shown, a shim 27 is provided between two adjacent second bearings 26. The shim 27 ensures the bearing spacing between the two adjacent second bearings 26, ensuring the stable operation of the drive shaft 40 and preventing wear caused by direct contact between the two adjacent second bearings 26. The end cap 23 is embedded in the fourth through hole 241 on the side near the mounting base 24, and a locking nut 28 is also fitted on the drive shaft 40. The locking nut 28 is located in the third through hole 231 and on the side of the second bearing 26 away from the shim 27. The locking nut 28 is used to stably restrict the second bearing 26 to the first shaft section 41 of the drive shaft 40.

The polishing apparatus provided in this embodiment significantly reduces the overall structural complexity of the polishing equipment, decreases the design difficulty and production cost, reduces the workload of programmers, and simplifies the structure of the polishing equipment, making it easy to maintain.

[0081] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
