[0002] The pneumatic actuator cylinder is mainly composed of a cylinder barrel, a piston rod, a guide sleeve, a sealing element, etc. Among them, an appropriate surface roughness of the inner wall of the cylinder barrel can reduce the friction between the cylinder and the piston, improve the sealing performance. If the surface of the inner wall of the cylinder barrel is too rough, it may lead to increased friction, oil film damage and cylinder wear, while if the surface is too smooth, it may lead to poor adhesion of lubricating oil.

[0003] Currently, generally, mechanical equipment is used to change the roughness of the inner wall of the cylinder barrel by polishing. However, during the polishing process of the cylinder barrel, due to the change in the specifications of the cylinder barrel, after the cylinder barrel is fixed, the center of the cylinder barrel and the polishing part are not in the same position (the same axis), and workers need to change the installation position of the polishing part or the fixing fixture to ensure that the polishing part can enter the inside of the cylinder barrel for processing. In the above process, the operation steps are cumbersome, reducing the polishing efficiency of the cylinder barrel; in addition, when polishing, an external robotic arm is used to pick up the workpiece.

Detailed implementation manners

[0018] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0019] The inner wall polishing device of a cylinder barrel according to an embodiment of the present application will be described below with reference to the drawings.

[0020] As Figures 1-6 shown, the inner wall polishing device of a cylinder barrel according to an embodiment of the present application may include: a fixing mechanism 1, a feeding box 2, and a polishing mechanism 3.

[0021] Among them, the fixing mechanism 1 includes a fixing frame 11 and a fixture assembly 12. Among them, both sides and the front of the fixing frame 11 are arranged in an open structure. The fixing frame 11 is used to support the fixture assembly 12. The fixture assembly 12 is installed on the fixing frame 11, and the fixture assembly 12 is used to fix the cylinder barrel to be polished.

[0022] It should be noted that both sides and the front of the fixing frame 11 are arranged in an open structure, which can facilitate the feeding process, polishing process, and unloading process.

[0023] The feeding box 2 is connected to the fixing frame 11. The feeding box 2 is located on one side of the fixing frame 11, and the feeding box 2 is used to temporarily store the cylinder barrels to be polished.

[0024] The polishing mechanism 3 includes a support assembly 31, a drive assembly 32, and a polishing assembly 33.

[0025] Among them, the support assembly 31 is connected to the fixing frame 11. The support assembly 31 is located on the other side of the fixing frame 11. The support assembly 31 is used to provide an installation platform for the drive assembly 32 and the polishing assembly 33 to ensure the reliability of the operation of the drive assembly 32 and the polishing assembly 33. The drive assembly 32 and the polishing assembly 33 are respectively installed on the support assembly 31. The polishing assembly 33 includes two second brackets 331, a guide rod 332, and a polishing piece 333.

[0026] Among them, the two second brackets 331 are respectively installed on the support assembly 31, and the guide rod 332 passes through the two second brackets 331.

[0027] It should be noted that in this embodiment, the guide rod 332 passes through the two second brackets 331. A first bearing is provided between the guide rod 332 and the second bracket 331. The guide rod 332 is in contact with the inner ring of the first bearing. The first bearing can not only assist the guide rod 332 to rotate, but also the guide rod 332 can slide between the two second brackets 331.

[0028] The guide rod 332 is connected to the drive assembly 32. The guide rod 332 is used to drive the polishing piece 333 to move. The polishing piece 333 is arranged at one end of the guide rod 332, and the polishing piece 333 is used to process the inner wall of the cylinder barrel.

[0029] In the embodiment of the present application, the external commercial power supplies the fixture assembly 12 and the polishing mechanism 3 in this device to ensure the normal operation of this device.

[0030] Specifically, when relevant technical personnel (such as workers) use this device to polish the inner walls of a batch of cylinder barrels, first, place multiple cylinder barrels to be polished inside the feeding box 2, and then start this device, and the polishing mechanism 3 starts to operate.

[0031] The driving assembly 32 drives the guide rod 332 and the polishing part 333 to move toward the direction of the feed box 2, and the guide rod 332 and the polishing part 333 pass through the clamp assembly 12. When the driving assembly 32 drives the guide rod 332 and the polishing part 333 to move to the first preset position (the preset position can be determined according to the actual situation, and this working condition can be obtained through the first position sensor), the polishing part 333 is deformed, and the polishing part 333 interacts with the inner wall of the cylinder barrel. The driving assembly 32 drives the guide rod 332 and the polishing part 333 to move away from the feed box 2 again. When the cylinder barrel is located inside the clamp assembly 12 (this working condition can be obtained through the second position sensor), the driving assembly 32 stops running, thereby realizing the loading process of the cylinder barrel.

[0032] The clamp assembly 12 starts to run, the clamp assembly 12 fixes the cylinder barrel, and the driving assembly 32 drives the guide rod 332 and the polishing part 333 to move toward the direction of the feed box 2 again. The polishing part 333 is placed at the bottom of the cylinder barrel, and the polishing part 333 applies a certain force to the inner wall of the cylinder barrel. The driving assembly 32 drives the guide rod 332 and the polishing part 333 to rotate. At the same time, the driving assembly 32 drives the guide rod 332 and the polishing part 333 to move away from the feed box 2 at a constant speed, thereby realizing the polishing process of the inner wall of the cylinder barrel.

[0033] After the polishing process is completed, the polishing part 333 interacts with the inner wall of the cylinder barrel, the clamp assembly 12 releases the fixation of the cylinder barrel, and the driving assembly 32 drives the guide rod 332 and the polishing part 333 to move away from the feed box 2 again until the cylinder barrel is separated from the clamp assembly 12, thereby facilitating the workers to remove the processed cylinder barrel. At this point, the unloading process of the cylinder barrel is completed.

[0034] The driving assembly 32 drives the guide rod 332 and the polishing member 333 to realize the loading, polishing and unloading of the cylinder barrel, replacing the high-cost robotic arm, thereby saving manpower and ensuring safe production while reducing the processing cost of the cylinder barrel.

[0035] If the specifications of the cylinder barrel are changed during the processing of the cylinder barrel, when loading the material, the polishing member 333 only needs to enter the interior of the cylinder barrel to drive the cylinder barrel to load the material.

[0036] The cylinder barrel can be clamped to the center axis position of the clamp assembly 12 in the clamp assembly 12, and the cylinder barrel, the clamp assembly 12 and the guide rod 332 always coincide with the center axis, thereby eliminating the need for workers to change the position of the clamp assembly and the polishing part, simplifying the operating steps and improving the polishing efficiency of the cylinder barrel.

[0037] It should be noted that the fixture assembly 12 and the polishing mechanism 3 in this device can be connected to an external control device, and workers can input operating data into the external control device, such as the operating speed of the driving assembly 32, etc., so as to achieve the purpose of controlling this device.

[0038] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the fixture assembly 12 includes two hinge members 122, two connecting rods 123, and two hydraulic telescopic rods 124.

[0039] Among them, the two hinge members 122 are symmetrically arranged inside the fixing frame 11. The two connecting rods 123 are respectively connected to one end of the two hinge members 122. The telescopic ends of the two hydraulic telescopic rods 124 are respectively connected to the corresponding connecting rods 123. One hydraulic telescopic rod 124 is installed at the bottom of the fixing frame 11, and the other hydraulic telescopic rod 124 is installed at the top of the fixing frame 11.

[0040] It should be noted that referring to Figure 2 , the hinge member 122 described in this embodiment is composed of four groups of hinge connecting rods, and the lengths of the four groups of hinge connecting rods are equal.

[0041] Specifically, during the operation of the fixture assembly 12, the two hydraulic telescopic rods 124 simultaneously pull the connecting rods 123 to move, and the connecting rods 123 drive the two hinge members 122 to deform, thereby fixing the cylinder barrel.

[0042] If the specifications of the cylinder barrel change, the two hinge members 122 can push the cylinder barrel to the central axis of the fixture assembly 12 during the deformation process, so that workers do not need to change the position of the fixture assembly and the polishing part, simplifying the operation steps and improving the polishing efficiency of the cylinder barrel.

[0043] In an embodiment of the present application, as Figure 1 and Figure 4 shown, the support assembly 31 includes a base 311, a rotating platform 312, and a vertical plate 313.

[0044] Among them, the base 311 is connected to the fixing frame 11. The rotating platform 312 is installed on the base 311. The second bracket 331 is connected to the rotating platform 312. The vertical plate 313 is arranged on the rotating platform 312.

[0045] It should be noted that the rotating platform 312 described in this embodiment may include a disc and a rotation driving device.

[0046] Specifically, during the unloading process, the driving component 32 drives the guide rod 332 and the polishing part 333 to move away from the feeding box 2, and the cylinder barrel disengages from the fixture component 12. Then, the rotary driving device drives the disc to rotate, that is, the rotary platform 312 drives the polishing mechanism 3 to rotate a certain angle (this working condition can be obtained through an angle sensor), for example: 60°, so as to facilitate the removal of the polished cylinder barrel.

[0047] It should be noted that the rotary platform 312 driving the polishing mechanism 3 to rotate 60° can make the processed cylinder barrel move away from the fixing mechanism 1.

[0048] In an embodiment of the present application, as Figure 1 and Figure 3 shown, the driving component 32 includes a lateral driving module 321, a driving motor 322, a driving wheel 323, a driven wheel 324, and a first bracket 325.

[0049] Among them, the lateral driving module 321 is installed on the vertical plate 313, the driving motor 322 is arranged on the slider of the lateral driving module 321, the driving wheel 323 is connected to the output shaft of the driving motor 322, the driven wheel 324 is connected to the guide rod 332, the driving wheel 323 and the driven wheel 324 are meshed and connected, one end of the first bracket 325 is installed on the slider of the lateral driving module 321, and the other end of the first bracket 325 is connected to the guide rod 332.

[0050] It should be noted that in this embodiment, the first bracket 325 and the guide rod 332 are rotatably connected by a second bearing, and the inner ring of the second bearing is connected to the guide rod 332.

[0051] Specifically, during the operation of the driving component 32, the lateral driving module 321 can drive the first bracket 325 to move, thereby pushing the guide rod 332 and the polishing part 333 to move away from and close to the feeding box 2.

[0052] During the polishing process, the driving motor 322 drives the driving wheel 323 to rotate, and the driving wheel 323 and the driven wheel 324 are meshed and connected, thereby driving the guide rod 332 to rotate, and further polishing the inner wall of the cylinder barrel.

[0053] In an embodiment of the present application, as Figure 1 、 Figure 3 and Figure 5 shown, the polishing part 333 includes two fixing blocks 3331, multiple groups of articulated rods 3332, two polishing blocks 3333, and two first telescopic rods 3334.

[0054] Wherein, a fixed block 3331 is installed at one end of a guide rod 332. The guide rod 332 penetrates through another fixed block 3331, and the guide rod 332 is slidably connected to the other fixed block 3331. One ends of multiple groups of hinged rods 3332 are respectively pivotally connected to the corresponding fixed blocks 3331, and the other ends of the multiple groups of hinged rods 3332 are respectively pivotally connected to the corresponding polishing blocks 3333. Two first telescopic rods 3334 are symmetrically arranged between the two fixed blocks 3331.

[0055] It should be noted that in this embodiment, the end position of the polishing block 3333 exceeds the end position of one fixed block 3331, or is flush with the end position of one fixed block 3331, that is, during the polishing process, the polishing block 3333 can polish the innermost wall of the deepest part of the cylinder barrel.

[0056] As a possible situation, in order to be able to polish the bottom wall of the cylinder barrel, polishing materials can be provided at the end of one fixed block 3331. The fixed block 3331 and the polishing block 3333 rotate simultaneously. Before the inner wall of the cylinder barrel is polished, as the distance between the two polishing blocks 3333 increases, the ends of the polishing block 3333 and the fixed block 3331 polish the bottom wall of the cylinder barrel simultaneously.

[0057] Specifically, during the processes of loading, polishing, and unloading, the two first telescopic rods 3334 drive the other fixed block 3331 to move, and the multiple groups of hinged rods 3332 are deformed, thereby changing the distance between the two polishing blocks 3333. When the first preset force (which can be determined according to the actual situation and this working condition can be obtained through a torque sensor) is reached between the polishing block 3333 and the inner wall of the cylinder barrel, the first telescopic rod 3334 stops operating, and the polishing block 3333 and the inner wall of the cylinder barrel interact to achieve clamping and fixing during the processes of loading and unloading.

[0058] When the second preset force is reached between the polishing block 3333 and the inner wall of the cylinder barrel, the first telescopic rod 3334 stops operating, and the polishing block 3333 and the inner wall of the cylinder barrel interact to achieve polishing of the inner wall of the cylinder barrel.

[0059] It can be understood that the cross-section of the polishing block 3333 is quadrilateral. In the early stage of using the polishing block 3333, when the polishing block 3333 contacts the inner wall of the cylinder barrel, it is two straight lines, and the contact area between the polishing block 3333 and the inner wall of the cylinder barrel is small, and the acting force is large to ensure the polishing efficiency; in the later stage of using the polishing block 3333, the edges and corners of the polishing block 3333 are ground round, the contact area between the polishing block 3333 and the inner wall of the cylinder barrel increases, and the acting force is small, which can also ensure the polishing efficiency.

[0060] In an embodiment of the present application, as Figure 1As shown in the figure, a buffer part 21 is provided at the bottom of the feeding box 2, a temporary storage part 22 is provided at the bottom of the feeding box 2, and an opening 23 is provided on one side of the feeding box 2 close to the fixing frame 11.

[0061] It should be noted that in this embodiment, the buffer part 21 is inclined, and the cross-section of the temporary storage part 22 is triangular.

[0062] It can be understood that multiple cylinder barrels in the feeding box 2 can enter the inside of the temporary storage part 22 along the buffer part 21. Only one cylinder barrel to be processed can be placed at the bottom of the temporary storage part 22. During the feeding process, the cylinder barrel can pass through the opening 23.

[0063] It should be noted that when the specification of the cylinder barrel changes, the cylinder barrel in the temporary storage part 22 and the guide rod 332 are not on the same central axis. When only the feeding condition needs to be met, the guide rod 332 and the polishing part 333 only need to meet the condition of entering the inside of the cylinder barrel. The polishing part 333 can clamp and fix the cylinder barrel, and it is not necessary to meet the requirement that the cylinder barrel in the temporary storage part 22 and the guide rod 332 are on the same central axis.

[0064] In an embodiment of the present application, as Figure 1 and Figure 6 shown in the figure, it further includes a recovery component 41 and a liquid spraying component 42.

[0065] Among them, the liquid spraying component 42 includes a liquid storage tank 421, a corrugated pipe 422 and a spray head 423. Among them, the liquid storage tank 421 is arranged on the support component 31. One end of the corrugated pipe 422 is communicated with the liquid storage tank 421. The spray head 423 is rotatably connected with the guide rod 332. The spray head 423 is located at the polishing part 333. The other end of the corrugated pipe 422 is connected with the spray head 423.

[0066] It should be noted that metal polishing liquid can be placed inside the liquid storage tank 421 in this embodiment. A pump body (not shown in the figure) is further provided inside the liquid storage tank 421. The pump body can pump the metal polishing liquid in the liquid storage tank 421 into the corrugated pipe 422 and finally spray it into the inside of the cylinder barrel through the spray head 423.

[0067] The recovery component 41 includes a collection box 411, a liquid collection box 412 and a pipe body 413. Among them, the liquid collection box 412 is arranged at the bottom of the fixing frame 11. One end of the pipe body 413 is communicated with the liquid collection box 412. The other end of the pipe body 413 is communicated with the collection box 411. The collection box 411 is located below one end of the cylinder barrel.

[0068] As a possible situation, the collection box 411 and the liquid storage tank 421 can be connected through a communication pipe (not shown in the figure). The collection box 411 can filter the metal polishing liquid. The processed metal polishing liquid can return to the inside of the liquid storage tank 421 for full use, so as to achieve the purpose of reducing costs.

[0069] In one embodiment of the present application, as Figure 1 shown, a limiting baffle 51 is provided on the fixing frame 11.

[0070] Specifically, the rotating platform 312 drives the polishing assembly 33 to rotate a certain angle for discharging. When the rotating platform 312 resets, the limiting baffle 51 can limit the vertical plate 313, thereby avoiding the situation that the polishing assembly 33 rotates excessively after long-term use.

[0071] As a possible situation, a rubber pad can be provided on the limiting baffle 51, which can play a role in buffering and sound absorption when the vertical plate 313 impacts the limiting baffle 51, thereby prolonging the service life of the limiting baffle 51.

[0072] In summary, for the inner wall polishing equipment of the cylinder barrel in the embodiments of the present application, the driving component drives the polishing component to move, the polishing part interacts with the inner wall of the cylinder barrel, the guide rod drives the polishing part and the cylinder barrel to move to the fixture component for loading. The fixture component can clamp the cylinder barrel of any specification at its central axis, without the need for workers to change the positions of the fixture component and the polishing part, thereby reducing the workload of workers and improving the polishing efficiency of the cylinder barrel. The polishing part enters the interior of the cylinder barrel for polishing. After that, the polishing part interacts with the inner wall of the cylinder barrel again, and the cylinder barrel can be separated from the fixture component to achieve discharging. Furthermore, while achieving the purposes of saving manpower and safe production, the processing cost of the cylinder barrel is reduced.
