DETAILED DESCRIPTION

[0031] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] See also Figure 1 , the embodiment of the present application provides a polishing machine 100, which includes a polishing device 2. Figure 2 The polishing device 2 includes a support assembly 21, a guide wheel assembly 22 and a polishing wheel assembly 23. The support assembly 21 is used to carry the roller 10. Figure 3 The guide wheel assembly 22 includes a guide wheel 221 and a first driver 222. The first driver 222 is drivingly connected to the guide wheel 221. The guide wheel 221 is rotatably connected to the support assembly 21. The rolling surface of the guide wheel 221 is used to contact the outer peripheral surface of the roller shaft 10 to drive the roller shaft 10 to rotate along its own axis. Figure 2The polishing wheel assembly 23 includes a polishing wheel 231 and a second driver (not shown in the figure). The second driver is drivingly connected to the polishing wheel 231, and the polishing wheel 231 is rotatably connected to the support assembly 21. The polishing surface of the polishing wheel 231 is used to contact the outer peripheral surface of the roller shaft 10 to polish the outer peripheral surface of the roller shaft 10. Figure 3 The first driver 222 in the guide wheel assembly 22 drives the guide wheel 221, which contacts the outer circumference of the roller shaft 10 and rotates the roller shaft 10 along its axis. This drive method allows for precise control of the rotational speed and direction of the roller shaft 10. For example, if the roller shaft 10 needs to be polished at a specific rotational speed, this can be achieved accurately by adjusting the parameters of the first driver 222, which helps ensure the stability and uniformity of the polishing process. The precisely controlled rotation of the guide wheel 221 avoids problems such as over-polishing or under-polishing in certain areas caused by uneven rotation of the roller shaft 10. The guide wheel 221 provides a relatively stable and low-friction rolling contact surface for the rotation of the roller shaft 10. Compared to some rough or inappropriate rotation guidance methods, the guide wheel 221 can reduce wear on the roller shaft 10 during rotation. The second driver in the polishing wheel assembly 23 drives the polishing wheel 231, ensuring that its polishing surface contacts the outer circumference of the roller shaft 10. The second driver provides sufficient power to the polishing wheel 231, ensuring that it operates at the appropriate speed and torque. For rollers 10 with higher hardness or greater surface roughness, powerful power can ensure that the polishing wheel 231 effectively removes material and improves polishing efficiency. The polishing wheel 231 is rotatably connected to the support assembly 21. This connection method ensures the stability of the polishing wheel 231 during operation. During polishing, the polishing wheel 231 can evenly contact the outer peripheral surface of the roller 10, so that the entire outer peripheral surface can be evenly polished. The guide wheel 221 drives the roller 10 to rotate and the polishing wheel 231 polishes the roller 10 in coordination with each other. The stable rotation guidance of the guide wheel 221 ensures that the roller 10 is always in contact with the polishing wheel 231 at a suitable posture and speed during the polishing process, making the polishing of the outer peripheral surface of the roller 10 by the polishing wheel 231 more precise and high-quality.

[0033] In an alternative embodiment, the first driver 222 and the second driver may be rotary motors or rotary cylinders.

[0034] See also Figure 2In some embodiments, the support assembly 21 includes a fixed structure 211 and a movable structure 212. The fixed structure 211 is used to support the roller 10. A guide wheel 221 is rotatably connected to the fixed structure 211. The main body of the first actuator 222 is fixedly mounted on the fixed structure 211. The polishing wheel 231 is rotatably connected to the movable structure 212. The main body of the second actuator is fixedly mounted on the movable structure 212. The movable structure 212 is used to drive the polishing wheel 231 to contact the outer circumference of the roller 10. The fixed structure 211 provides a stable supporting platform for the roller 10. Because the roller 10 must maintain a precise position and posture during the polishing process, the fixed structure 211 effectively prevents the roller 10 from shaking or shifting due to external factors (such as vibration and displacement). The movable structure 212 allows for convenient adjustment of the position of the polishing wheel 231 to ensure accurate contact with the outer circumference of the roller 10. This flexibility is very useful when polishing rollers 10 of different sizes and shapes. For example, when it is necessary to polish rollers 10 of different diameters, the distance between the polishing wheel 231 and the roller 10 can be adjusted by the movable structure 212 to ensure good contact between the polishing wheel 231 and the outer peripheral surface of the roller 10. At the same time, when installing or disassembling the roller 10, the movable structure 212 can move the polishing wheel 231 to a safe position to prevent damage to the polishing wheel 231 during operation.

[0035] See also Figure 3 In some optional embodiments, the fixed structure 211 includes a base 2111 and two oppositely disposed bearing seats 2112. The bearing seats 2112 are fixedly mounted at both ends of the base 2111. The two ends of the guide wheel 221 are rotatably connected to the two bearing seats 2112, respectively. The main body of the first driver 222 is fixedly mounted on one of the bearing seats 2112, and the output end of the first driver 222 is drivingly connected to one end of the guide wheel 221. The fixed structure 211 also includes a limiting plate 2113 and a limiting bar 2114. The limiting plate 2113 is recessed with a limiting groove 2115. The limiting bar 2114 is fixedly mounted on the side of the limiting plate 2113. The limiting groove 2115 is used to accommodate the roller shaft 10, and the limiting bar 2114 is used to radially limit the roller shaft 10 to prevent the roller shaft 10 from rolling out of the limiting groove 2115.

[0036] See also Figure 2 In some optional embodiments, the moving structure 212 may be a linear moving module, such as a belt linear moving module, a gear rack linear moving module, a ball screw linear moving module or a linear motor moving module, etc. The linear moving module can be purchased commercially and will not be described in detail here.

[0037] See also Figure 1 and Figure 2 In some embodiments, the polishing machine 100 further includes a machine platform 1, and a polishing device 2 is disposed on the machine platform 1. The machine platform 1 is used to support the polishing device 2. Figure 1 In some embodiments, the polishing machine 100 further includes a feeding device 3, a lifting device 5, a translation device 6 and a gripping device 4. The feeding device 3 is connected to the jig 32 (see Figure 5 ) transports the roller 10 to the lifting device 5, which is used to lift the jig 32 to the point where the translation device 6 can hold the jig 32, and the grasping device 4 grasps the roller 10 in the jig 32 to the support assembly 21 of the polishing device 2 for polishing.

[0038] In an alternative implementation, see Figure 4 The feeding device 3 may include a feeding vehicle 31 or a conveyor belt. The feeding device 3 can continuously transport the roller 10 to the designated location, avoiding damage to the surface of the roller 10 caused by accidental collision or falling when the roller 10 is manually transported.

[0039] See also Figure 4 and Figure 5 In some embodiments, the feed device 3 includes a feed trolley 31 and a jig 32. The feed trolley 31 is located outside the machine 1 and is used to carry the jig 32. The edge of the jig 32 protrudes from the feed trolley 31. The jig 32 is recessed with a receiving groove 3221 for accommodating the roller 10. The feed trolley 31 is used to move the jig 32 toward the machine 1. Because the edge of the jig 32 protrudes from the feed trolley 31, it can provide a lifting position and operating space for the lifting device 5, so that the lifting device 5 can more conveniently lift the jig 32.

[0040] See also Figure 1 In an optional embodiment, the number of the feeding carts 31 may include one, two, three, etc.

[0041] See also Figure 5 In an optional embodiment, the jig 32 includes two connected support bars 321 and two connecting bars 322. The two support bars 321 are arranged opposite each other and spaced apart, and the two connecting bars 322 are arranged between the two support bars 321, so that the jig 32 is in the shape of a square. Both ends of the two support bars 321 protrude from the two connecting bars 322 and the feeding cart 31.

[0042] See also Figure 5In an optional embodiment, each connecting strip 322 has a recessed receiving groove 3221 on the side facing the other connecting strip 322 for accommodating the roller shaft 10. At least a portion of the roller shaft 10 along its radial direction protrudes from the receiving groove 3221, so that this portion is located above the top surface of the connecting strip 322, which facilitates grasping by the grasping device 4. In an optional embodiment, to further facilitate grasping by the grasping device 4, a first retaining groove 3222 may be recessed on the top surface of the connecting strip 322. The first retaining groove 3222 communicates with the receiving groove 3221 and can be used to prevent the grasping device 4 from grasping the roller shaft 10.

[0043] See also Figure 5 In an optional embodiment, a second slot 3211 is formed on the side of each support bar 321 , and the second slot 3211 can facilitate the holding of the translation device 6 .

[0044] In an optional embodiment, when the roller 10 is placed in the receiving groove 3221 of the clamping strip 322, the roller 10 and the clamping strip 322 are located between the top and bottom surfaces of the support strip 321, thereby facilitating stacking of multiple jigs 32 without squeezing the roller 10.

[0045] See also Figure 6 In some embodiments, the lifting device 5 includes a third driver 51, a lifting screw 52 and a lifting bracket 53. The lifting screw 52 moves in a first direction (eg Figure 6 The lifting mechanism 53 is connected to the machine 1 (seeing the AA direction shown). One end of the lifting screw 52 is driven by the third driver 51, and the other end is rotatably connected to the machine 1. The lifting bracket 53 is transmission-connected to the lifting screw 52. The lifting bracket 53 has a first hollow portion that is used to avoid the feed device 3. The lifting device 5 is used to lift the jig 32 on the feed cart 31. It will be understood that the third driver 51 drives the lifting screw 52 to rotate. The lifting bracket 53 is transmission-connected to the lifting screw 52, ​​and the threaded drive converts the rotational motion of the lifting screw 52 into linear motion of the lifting bracket 53. After the feed cart 31 is pushed into the first hollow portion of the lifting bracket 53, the lifting bracket 53, driven by the third driver 51, descends to a position below the edge of the jig 32. The lifting bracket 53, driven by the third driver 51, then rises to lift the jig 32, completing the transfer of the jig 32 from the feed cart 31 to the lifting bracket 53.

[0046] See also Figure 1 In an optional embodiment, the number of the lifting devices 5 may include one, two, three, etc. The plurality of lifting devices 5 may be spaced apart along the width direction (i.e., the second direction) of the machine platform 1. Each lifting device 5 may correspond to a feed cart 31.

[0047] In an optional embodiment, the third driver 51 may be a rotary motor or a rotary electric cylinder.

[0048] In some embodiments, the lifting device 5 further includes a lifting support plate 54, a synchronous belt 55 and a synchronous wheel 56. The third driver 51 is provided on the side of the lifting support plate 54 facing the machine 1. The lifting screw 52 and the lifting bracket 53 are provided on the side of the lifting support plate 54 facing away from the machine 1. The lifting screw 52 includes a first direction (such as Figure 6 The first and second ends of the lifting device 1 are rotatably connected to the lifting support plate 54 (in the direction AA shown in FIG. 1 ). The first direction is along the height of the machine platform 1. The first and second ends are both rotatably connected to the lifting support plate 54. The second end and the output end of the third driver 51 both protrude from the bottom edge of the lifting support plate 54. The synchronous pulleys 56 are respectively sleeved on the second end and the output end of the third driver 51. The synchronous belt 55 is simultaneously wound around all of the synchronous pulleys 56. In other words, the synchronous belt 55, synchronous pulleys 56, and third driver 51 are all located at the bottom of the lifting support plate 54, avoiding being located at the top of the lifting support plate 54 and interfering with the installation and movement of the grasping device 4.

[0049] See also Figure 6 In an optional embodiment, the lifting device 5 further includes a lifting guide rail 57 and a lifting slide seat 58. The lifting guide rail 57 is arranged along a first direction (eg Figure 6 The lifting bracket 53 is fixed on the lifting slide seat 58. The lifting guide rail 57 and the lifting slide seat 58 can guide the movement of the lifting bracket 53.

[0050] See also Figure 6 In an optional embodiment, the lifting bracket 53 includes a connecting plate 531 and two supporting plates 532. The two supporting plates 532 are vertically arranged on either side of the connecting plate 531 to form a first hollow portion. The connecting plate 531 is in driving connection with the lifting screw 52 and is fixed to the lifting slide 58. During operation of the lifting device 5, the lifting bracket 53 descends, causing the two supporting plates 532 to descend to the bottom edge of the fixture 32. The lifting bracket 53 then ascends, and the supporting plates 532 lift the edge of the fixture 32.

[0051] See also Figure 1 In some embodiments, the translation device 6 is located above the lifting device 5. Figure 7 The translation device 6 includes a fourth driver 61, a translation screw 62 and a translation bracket 63, and the translation screw 62 moves along the second direction (such as Figure 7A translation mechanism 6 is provided on the machine 1 (in the BB direction shown), with the second direction being the width direction of the machine 1. One end of a translation screw 62 is drivingly connected to the fourth driver 61, and the other end is rotationally connected to the machine 1. A translation bracket 63 is transmission-connected to the translation screw 62. The translation bracket 63 has a second hollow portion, which is used to avoid the lifting device 5. The translation bracket 63 is used to clamp the jig 32 on the lifting device 5. A translation device 6 is provided, and the translation device 6 can move laterally above different lifting positions, thereby accommodating jigs 32 from different lifting devices 5. It will be understood that when the translation device 6 moves above a certain lifting device 5, the lifting device 5 continues to rise until its lifting bracket 53 is flush with the translation bracket 63, and the translation bracket 63 clamps the jig 32 on the lifting bracket 53.

[0052] In an optional embodiment, the fourth driver 61 may be a rotary motor or a rotary electric cylinder.

[0053] See also Figure 8 In some embodiments, the translation bracket 63 includes two connected bracket arms 636 and a fifth driver 631, a first slide rail 632, a second slide rail 633, a clamping member 634 and an adapter 635 respectively provided on each bracket arm 636. The two bracket arms 636 are configured to form a second hollow portion. The first slide rail 632 is movable along the third direction (such as Figure 8 The third direction is along the length of the bracket arm 636. The fifth driver 631 is driven to connect to the adapter 635. The adapter 635 is slidably connected to the first slide rail 632. The adapter 635 is provided with a guide rail 6351. The guide rail 6351 extends along the fourth direction (as shown in FIG. Figure 8 The clamping member 634 is provided with a guide post 6341, which is transmission-connected to the guide rail 6351. The clamping member 634 is slidably connected to the second slide rail 633. The second slide rail 633 is relative to the first slide rail 632 along the fifth direction (as shown in FIG. Figure 8The third direction (CC direction), the fourth direction (DD direction), and the fifth direction (EE direction) are inclined toward the second hollow portion. The clamping member 634 is used to clamp the jig 32. The third direction (CC direction), the fourth direction (DD direction), and the fifth direction (EE direction) intersect with each other. It can be understood that the fifth driver 631 drives the adapter 635 to move along the first slide rail 632. Due to the transmission connection between the guide rail 6351 on the adapter 635 and the guide post 6341 on the clamping member 634, the guide rail 6351 and the guide post 6341 interact with each other, causing the guide post 6341 to move along the guide rail 6351. Simultaneously, the adapter 635 pushes the clamping member 634 along the second slide rail 633, causing the clamping member 634 to move toward the second hollow portion. When the lifting bracket 53 of the lifting device 5 is aligned with the translation bracket 63, the clamping member 634 moves into the second hollow portion to clamp the jig 32 on the lifting bracket 53. Specifically, the clamping member 634 is clamped in the third clamping slot on each support bar 321 of the fixture 32 .

[0054] In an alternative embodiment, the gripping device 4 may be a robotic arm, a vacuum cup gripping device, a pneumatic gripping device, etc. It is understood that the gripping device 4 can be used to automate the loading process. The gripping device 4 can grasp and place the roller 10 according to a preset precise action, thereby avoiding human error, ensuring the integrity of the roller 10 before entering the polishing process, and improving the quality of the polished product.

[0055] See also Figure 9 In some embodiments, the gripping device 4 includes a motion component 41 and a clamping component 42 connected to each other. The motion component 41 is used to drive the clamping component 42 to move. Figure 10 The jaw assembly 42 includes a jaw driver 421 and jaws 422. The main body of the jaw driver 421 is fixed to the motion assembly 41. The jaw driver 421 is connected to the jaws 422 to drive the jaws 422 to open or close. The motion assembly 41 can drive the jaw assembly 422 to a position where the jaw assembly 42 can grasp the roller shaft 10. The jaw driver 421 drives the jaws 422 to open and grasp the roller shaft 10.

[0056] In an optional embodiment, the motion component 41 may be a lifting motion component 412, or a horizontal motion component 411, or a combination of the two, that is, the motion component 41 can realize both lifting motion and horizontal motion.

[0057] In an optional embodiment, the motion component 41 includes a horizontal motion component 411 and a lifting motion component 412 .

[0058] The horizontal motion component 411 is a linear motion module, for example, a belt linear motion module, a gear rack linear motion module, a ball screw linear motion module or a linear motor motion module, etc. The linear motion module can be purchased from the market and will not be described in detail here.

[0059] The lifting motion component 412 can be a lifting cylinder, a lifting electric cylinder or a lifting motor. Taking the lifting cylinder as an example, the output end of the lifting cylinder is connected to the clamping claw component 42 and can drive the clamping claw component 42 to rise or fall.

[0060] See also Figure 10 and Figure 11 In an optional embodiment, the clamping jaw 422 includes a clamping jaw support 4221, and a first fixed shaft 4222, a first clamping block 4223, a second fixed shaft 4224, a second clamping block 4225, and a connecting block 4226, which are arranged in pairs on both sides of the clamping jaw support 4221. The clamping jaw support 4221 is connected to the motion assembly 41, and the clamping jaw driver 421 is fixed to the clamping jaw support 4221. One end of the first fixed shaft 4222 is fixed to the clamping jaw support 4221 in the vertical direction, and the other end is connected to the first clamping block 4223. The connecting block 4226 is drivingly connected to the output end of the clamping jaw driver 421. One end of the second fixed shaft 4224 is fixed to the connecting block 4226, and the other end is connected to the second clamping block 4225. The second clamping block 4225 is located on the outside of the first clamping block 4223. The clamping jaw driver 421 drives the connecting blocks 4226 and the second fixed shaft 4224 on both sides to move the second clamping blocks 4225 away from each other, so that the second clamping blocks 4225 on each side are away from the first clamping blocks 4223 on the same side, thereby opening the clamping jaws 422 to a space large enough to accommodate the roller shaft 10. The clamping jaw driver 421 drives the connecting blocks 4226 and the second fixed shaft 4224 on both sides to move the second clamping blocks 4225 toward each other, so that the second clamping blocks 4225 on each side are close to the first clamping blocks 4223 on the same side, thereby causing the clamping jaws 422 to grasp the roller shaft 10.

[0061] In an optional embodiment, the bottom surface of the first clamping block 4223 is provided with an arc-shaped groove, which matches the shape of the outer circumference of the roller shaft 10. The second clamping block 4225 is an L-shaped clamping block that can extend into the interior of the roller shaft 10 and lift the circumferential edge of the roller shaft 10.
