[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] This embodiment provides a grinding and polishing device, which includes a moving device and a grinding and polishing device, the grinding and polishing device is connected to the moving device, and the moving device can drive the grinding and polishing device to move along the X-axis and / or the Y-axis. However, the grinding and polishing device in the prior art has the disadvantages of being large in size, insufficient in flexibility, and unable to adapt to the change of the surface curvature of the workpiece to be polished and perform constant force grinding and polishing. Therefore, this embodiment also provides a grinding and polishing device that can solve the above technical problems.

[0040] like Figure 1-Figure 5 As shown, the grinding and polishing device includes an adjustment mechanism 10, a force control mechanism 20, a grinder 30 and a dust collecting mechanism 40. Specifically, the adjustment mechanism 10 includes a first driving member 11 and an adjustment assembly 12, the adjustment assembly 12 includes a connecting plate 121, a movable plate group and a support plate 125 arranged at intervals along the Z axis (vertical direction), the top surface of the connecting plate 121 is connected to the output end of the first driving member 11, the connecting plate 121 and the support plate 125 are connected through a first guide shaft 126, and the first guide shaft 126 passes through the movable plate group, the outer periphery of the movable plate group is connected to a fixed plate 124, the fixed plate 124 is used to connect the moving device, and the movable plate group is configured to be able to rotate around the X axis and / or the Y axis; the force control mechanism 20 is located inside the adjustment mechanism 10; the grinder 30 is connected to the output end of the force control mechanism 20, and the force control mechanism 20 can control the grinding pressure of the grinder 30; the dust collecting mechanism 40 is arranged at the top of the adjustment mechanism 10, and is configured to be able to absorb dust generated by the grinder 30.

[0041] When grinding a workpiece, the output end of the first driving member 11 pushes the connecting plate 121, and then indirectly pushes the force control mechanism 20 and the grinder 30 to approach the surface of the workpiece to be grinded through the connecting plate 121; when the surface of the workpiece to be grinded is a curved surface, under the dual force of the curved surface and the first driving member 11, the movable plate group begins to rotate around the X-axis or Y-axis until the axial direction of the grinding and polishing device as a whole along the Z-axis (vertical direction) is the same as the normal direction of the local curved surface, and the grinding and polishing device can remain stable and perform grinding. In this process, since the fixed plate 124 is always connected to the mobile device and remains stationary, the stability of the process is guaranteed. And during the grinding process, the force control mechanism 20 can ensure that the grinding pressure remains unchanged, thereby ensuring a good grinding effect.

[0042] It is worth noting that, in this embodiment, the workpiece to be polished is an aircraft skin. In other embodiments, the surfaces of other workpieces can also be polished, and this embodiment does not limit the scope of use of the device. In addition, the first driving member 11 is a cylinder, which has a simple structure, low price, and is easy to install, which effectively reduces the manufacturing cost of the device. It is further explained that, in this embodiment, the mobile device is a wall-climbing robot. Compared with the transmission robot, the wall-climbing robot has the characteristics of small size and high efficiency.

[0043] like Figure 1-Figure 3 As shown, the movable plate group includes a first movable plate 122 and a second movable plate 123, the first movable plate 122 and the second movable plate 123 are connected by two first rotating shafts 13, the second movable plate 123 and the fixed plate 124 are connected by two second rotating shafts 14, the line connecting the two first rotating shafts 13 is the first axis, the line connecting the two second rotating shafts 14 is the second axis, the first axis is parallel to the Y axis, and the second axis is parallel to the X axis. This structure can ensure that when the polishing device abuts against the curved surface, the first movable plate 122 and the second movable plate 123 rotate around the Y axis and the X axis respectively, and the overall structure is simple.

[0044] It should be noted here that, in this embodiment, the first rotating shaft member 13 and the second rotating shaft member 14 are both damping rotating shafts. The damping rotating shaft has a simple structure, is easy to install, and has a wide range of uses. The relative movement or inertial movement between the two moving parts can cause the damping rotating shaft to rotate, and during the rotation process, a damping force can be generated inside. The damping force is transmitted to the moving parts to slow down their speed, avoiding large-scale shaking, and the deceleration effect is good.

[0045] In addition, in order to ensure that the first driving member 11 drives the connecting plate 121 to move along the Z-axis direction more smoothly, as shown in FIG. Figure 1-Figure 3As shown, at least two first guide shafts 126 are provided, and at least two first guide shafts 126 are symmetrically distributed along the two sides of the first axis. It should be noted here that, in the present embodiment, there are two first guide shafts 126, and both first guide shafts 126 are slidably connected to the first movable plate 122 through the first linear bearing 19. Since the first movable plate 122 is connected to the second movable plate 123, and the second movable plate 123 is connected to the fixed plate 124, when the first driving member 11 drives the connecting plate 121 to move along the Z axis, the first guide shaft 126 can slide relative to the first movable plate 122; when the grinder 30 contacts the curved surface, the first movable plate 122 can rotate around the first axis, and the left and right sides rise or fall respectively along the left and right two first guide shafts 126, thereby completing the posture adjustment.

[0046] To simplify the overall structure, Figure 1-Figure 3 As shown, the adjustment assembly 12 also includes a top plate 127, which is located above the connecting plate 121, and the first driving member 11 is arranged on the top plate 127. The output end of the first driving member 11 can pass through the top plate 127 and be connected to the top surface of the connecting plate 121. The side of the top plate 127 away from the first driving member 11 is connected to the first movable plate 122 through the floating member 15. The top plate 127 is arranged above the connecting plate 121, and the first driving member 11 is fixed on the top plate 127, which is conducive to reducing the overall size of the device. The top plate 127 is connected to the first movable plate 122 by the floating member 15, which can ensure that when the first movable plate 122 rotates around the first axis, the floating member 15 can float up and down (extend and retract) along the Z axis, so as not to affect the fixation of the top plate 127.

[0047] It is worth mentioning that in this embodiment, the floating member 15 is a floating support shaft. When the first movable plate 122 does not rotate, the floating support shaft can support and fix the top plate 127. When the first movable plate 122 rotates around the first axis, the floating support shaft can float up and down (extend and retract) along the Z axis to ensure that the first movable plate 122 can rotate normally without affecting the fixation of the top plate 127.

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, the force control mechanism 20 is arranged between the connecting plate 121 and the supporting plate 125, and the force control mechanism 20 includes a second driving member 21 and a sensor member 22 which are sequentially connected along the Z-axis direction. The second driving member 21 is arranged on the bottom surface of the connecting plate 121, and the second driving member 21 is communicatively connected with the sensor member 22. The other end of the sensor member 22 is connected to the grinder 30. The second driving member 21 can drive the grinder 30 to move along the Z-axis direction, and the sensor member 22 can keep the grinding pressure of the grinder 30 constant.

[0049] It should be noted here that avoidance holes are provided in the centers of the first movable plate 122 and the support plate 125, so that the force control mechanism 20 can move along the Z axis in the avoidance hole, thereby not causing an increase in the overall size of the grinding and polishing device; in addition, the second driving member 21 can indirectly push the grinder 30 to contact the surface of the workpiece to be polished by pushing the sensor 22, thereby facilitating polishing and avoiding the situation where the grinder 30 cannot touch the workpiece to be polished; in addition, the sensor 22 can indirectly determine the pressure of the grinder 30 on the surface of the workpiece to be polished by measuring the pressure applied to itself by the second driving member 21, which greatly simplifies the mechanical model and facilitates the control of the pressure applied by the grinder 30 to the surface of the workpiece to be polished; since the sensor 22 and the second driving member 21 are in communication connection, when the pressure value changes, the sensor 22 transmits a signal to the second driving member 21 so that the second driving member 21 drives the grinder 30 to rise or fall along the Z axis, thereby keeping the polishing pressure constant.

[0050] It should be noted here that, since the force control mechanism 20 is independently arranged inside the adjustment component 12, when the second drive member 21 adjusts the grinding pressure, it will not affect the fixed position of the grinding and polishing device, thereby ensuring a good use effect. It is further explained that, in the present embodiment, the second drive member 21 is a telescopic servo stepper motor, which has a simple structure, precise control, and is easy to install. In other embodiments, the second drive member 21 can also be a structure such as a driving cylinder. In addition, the sensor 22 is a force sensor, which has a simple structure and is easy to use. It can quickly respond to the applied force and convert the force value into a measurable value. In addition, the grinder 30 is a pneumatic grinder, which is small in size and light in weight, which is conducive to reducing the overall size.

[0051] In addition, if Figure 1 , Figure 2 and Figure 4 As shown, the second driving member 21 is arranged at the center of the connecting plate 121, and a plurality of second guide shafts 16 are arranged between the connecting plate 121 and the supporting plate 125 along the Z-axis direction, and the sensing member 22 is slidably connected with the plurality of second guide shafts 16. This structure can make the axis direction of the force control mechanism 20 and the adjustment mechanism 10 always consistent, thereby ensuring a good grinding effect; in addition, by providing a plurality of second guide shafts 16, the second driving member 21 can drive the sensing member 22 and the grinder 30 to move along the Z-axis without deviating from the preset direction.

[0052] It should be noted here that the top of the sensor 22 is provided with a connecting top plate 23, and the bottom is provided with a connecting bottom plate 24. The second guide shaft 16 passes through the connecting top plate 23 through the second linear bearing 25, and the grinder 30 is connected to the sensor 22 through the connecting bottom plate 24. This structure facilitates the connection between the sensor 22 and the second guide shaft 16 and the grinder 30, and is also conducive to ensuring the service life of the sensor 22. In addition, three second guide shafts 16 are evenly arranged along the circumference of the sensor 22. In other embodiments, the number of second guide shafts 16 can be adjusted according to actual needs, and no other restrictions are made in this embodiment.

[0053] like Figure 2-Figure 4 As shown, the adjustment assembly 12 further includes a bottom plate 128, which is disposed at the bottom of the support plate 125. The support plate 125 and the bottom plate 128 are connected by a plurality of support members 17 to form an accommodation space 18, and the accommodation space 18 can accommodate the grinder 30. This structure can place the grinder 30 in the accommodation space 18, thereby avoiding collision between the grinder 30 and the outside, thereby extending the service life of the grinder 30.

[0054] like Figure 1 and Figure 5 As shown, the dust collecting mechanism 40 includes a sealing cover 41, a connecting pipe 42, a dust box 43 and an adsorbent 44. The sealing cover 41 is arranged on the outer periphery of the accommodating space 18 and forms a negative pressure chamber. The dust box 43 is arranged at the top end of the top plate 127 of the adjusting mechanism 10. The adsorbent 44 is arranged at the top end of the dust box 43 and is connected with the dust box 43. The connecting pipe 42 is located inside the adjusting mechanism 10, and one end is connected with the negative pressure chamber, and the other end is connected with the dust box 43, so that the dust in the negative pressure chamber can be adsorbed into the dust box 43.

[0055] By providing a sealing cover 41 on the outer periphery of the accommodating space 18, dust can be easily adsorbed and dust can be prevented from diffusing in the air and affecting the working environment. At the same time, since the dust collecting box 43 and the adsorbent 44 are all arranged at the top of the top plate 127, it is beneficial to further reduce the overall size of the device. At the same time, since the connecting pipe 42 can be arranged inside the adjustment component 12 and connect the negative pressure chamber with the dust collecting box 43, the negative pressure effect generated by the adsorbent 44 can be smoothly transferred to the negative pressure chamber while reducing the size, and negative pressure can be quickly formed, thereby ensuring a good use effect.

[0056] It should be noted here that the adsorbent 44 is a vacuum generator, which has a low cost and can quickly form negative pressure to ensure the efficiency of adsorbing dust. In addition, the two ends of the sealing cover 41 are bonded between the support plate 125 and the bottom plate 128. Therefore, in order to further ensure the sealing of the negative pressure chamber, a sealing plate 46 is also provided inside the negative pressure chamber, and the sealing plate 46 is bonded to the bottom end of the support plate 125, thereby ensuring good sealing.

[0057] In addition, if Figure 5 As shown, the dust collecting mechanism 40 further includes a flexible skirt 45, which is disposed at the bottom end of the bottom plate 128; by providing the flexible skirt 45, the dust collecting mechanism 40 can be ensured to change its curved surface, thereby ensuring good air tightness, and thus facilitating the formation of a negative pressure effect in the negative pressure chamber. The flexible skirt 45 can be any structure such as silicone, rubber, sponge, etc., and the material is not specifically limited in this embodiment.

[0058] In addition, if Figure 3 As shown, a universal member 129 is also provided at the bottom end of the bottom plate 128. Three universal members 129 are evenly provided along the circumference of the bottom plate 128. It should be noted here that the universal member 129 is a bull's eye bearing, which can reduce friction resistance when in contact with the surface of the workpiece to be polished, and is conducive to moving along the curved surface. In addition, the universal member 129 can work with the first movable plate 122 and the second movable plate 123 to complete the adjustment of the overall posture of the polishing device.

[0059] Finally, the use process of the grinding and polishing device in this embodiment is described in conjunction with the accompanying drawings:

[0060] First, the first driving member 11 drives the connecting plate 121 to descend along the Z-axis direction until the universal member 129 contacts the surface of the workpiece to be polished, and the first movable plate 122 and the second movable plate 123 rotate around the Y-axis and the X-axis respectively, so that the polishing device can follow the shape of the surface of the workpiece to be polished.

[0061] Secondly, the second driving member 21 drives the grinder 30 to move along the Z-axis direction until a suitable grinding pressure is formed with the surface of the workpiece to be grinded, and the sensor 22 can always keep the grinding pressure constant and perform grinding.

[0062] Finally, the adsorption element 44 forms a negative pressure in the adsorption chamber to adsorb the dust into the dust collecting box 43 .

[0063] According to the above operation process, 48 ​​grinding points are selected on the surface of the workpiece to be polished for testing. The surface roughness data (unit: micrometer) of the 48 grinding points after polishing by the polishing device in this embodiment are shown in the following table:

[0064] 1.550 1.266 1.271 1.356 1.453 1.327 1.367 1.306 1.197 1.415 1.552 1.344 1.616 1.266 1.581 1.602 1.109 1.363 1.286 1.496 1.636 1.472 1.260 1.594 1.648 1.263 1.443 1.405 1.575 1.504 1.490 1.634 1.309 1.297 1.590 1.479 1.421 1.357 1.468 1.607 1.450 1.213 1.349 1.538 1.405 1.282 1.368 1.598

[0065] Through the above data analysis, it can be obtained that the fluctuation range of the surface roughness after grinding is within 0-0.539 microns, and there is no phenomenon of over-grinding or under-grinding. The surface consistency is high and the use effect is good.
