Description

Technical Field

[0001] This disclosure pertains to the field of machining, and in particular relates to a grinding device. Background Technology

[0002] After machining is completed, in order to ensure the precision of the parts, they need to be polished with sandpaper of different grits to different degrees.

[0003] In related technologies, belt sanders are typically used for grinding shaft-type components. A belt sander includes a frame and sandpaper mounted on the frame. The sandpaper is driven by two spools. During grinding, the component is rotatably positioned between the two spools and in close contact with the sandpaper, which continuously circulates. This process allows for the grinding and polishing of the component.

[0004] However, when using a belt sander to polish parts, the sandpaper's width is limited, much smaller than the length of the shaft-like parts. Therefore, during polishing, the sandpaper needs to be moved intermittently along the length of the shaft-like parts. The edge of the sandpaper may bend inwards (towards the polishing surface) or deform. During movement, if the sandpaper's edge bends inwards, it will polish the non-polishing areas of the shaft-like parts, rendering the parts unusable. Summary of the Invention

[0005] This disclosure provides a grinding device that can improve the grinding effect of parts. The technical solution is as follows:

[0006] This disclosure provides a polishing apparatus, which includes a fixed base, a polishing assembly, and at least one pair of guide assemblies. The polishing assembly includes sandpaper and two drive rollers, which are arranged in parallel and rotatably connected to the fixed base. The two ends of the sandpaper in the length direction are respectively wound around the two drive rollers, and the sandpaper has a polishing surface for polishing parts. Each of the at least one pair of guide assemblies is connected to the fixed base. Each pair of guide assemblies is symmetrically arranged on opposite sides of the sandpaper in the width direction between the two drive rollers, and each pair of guide assemblies is configured to bend the opposite sides of the sandpaper in the width direction between the two drive rollers toward the opposite side of the polishing surface.

[0007] In another implementation of this disclosure, the guiding assembly includes a guide member and a locking pin; the guide member is hinged to the fixed seat, the axis of the hinge axis between the guide member and the fixed seat is in the same direction as the arrangement direction of the two drive rollers, and the guide member has a guide groove for accommodating the side of the sandpaper; the locking pin is connected to the guide member and the fixed seat respectively to lock the guide member and the fixed seat, such that the angle between the opening direction of the guide groove and the reference plane is an acute angle, and the reference plane is the plane containing the axes of the two drive rollers.

[0008] In another implementation of this disclosure, the guide assembly further includes a guide wheel, which is located between two guide members in the same pair of guide assemblies and on the back side of the sandpaper. The back side and the polishing surface are opposite to the sandpaper. The guide wheel is rotatably connected to the fixed base, and the outer periphery of the guide wheel is in contact with the bend in the width direction of the sandpaper.

[0009] In another implementation of this disclosure, the fixed base includes a base body, a lifting drive rod, and a lifting plate. The top of the base body has a mounting groove located between the two drive rollers. The lifting drive rod is located within the mounting groove, and one end of the lifting drive rod is connected to the base body. The lifting drive rod is capable of extending and retracting along a direction perpendicular to the sandpaper located between the two drive rollers. The lifting plate is located within the mounting groove, and the side of the lifting plate away from the sandpaper is connected to the other end of the lifting drive rod. The side of the lifting plate facing the sandpaper is connected to each of the guide components.

[0010] In another implementation of this disclosure, the sanding device further includes a support assembly located in the mounting groove and in the lifting plate, the support assembly being connected to the lifting plate, and the support assembly being configured to extend and retract in a direction perpendicular to the sandpaper located between the two drive rollers to contact the sandpaper.

[0011] In another implementation of this disclosure, the support assembly includes two elastic support units, which are spaced apart in the mounting groove along the arrangement direction of the two drive rollers. Each elastic support unit includes a support rod, a first outer cylinder, and a first elastic element. One end of the support rod is located on the side of the sandpaper facing the lifting plate and is in contact with the sandpaper. The second end of the support rod is slidably located inside the top of the first outer cylinder, and the bottom of the first outer cylinder is connected to the lifting plate. The first elastic element is located inside the first outer cylinder, and both ends are clamped between the support rod and the first outer cylinder.

[0012] In another implementation of this disclosure, the bottom of the first outer cylinder in the elastic support unit is slidably connected to the lifting plate, and the moving direction of the first outer cylinder is the length direction of the sandpaper; the support assembly further includes a connecting unit, which is located between the two elastic support units, and the connecting unit is connected to the two first outer cylinders respectively to adjust the distance between the two first outer cylinders.

[0013] In another implementation of this disclosure, the grinding device further includes a clamping assembly comprising a clamping frame, two clamping members, and a clamping drive member; the clamping frame is at least partially suspended above the fixed base, and has a clamping space for accommodating the component on the side facing the fixed base; the two clamping members are spaced apart within the clamping space along the axis of the drive reel, and both clamping members are connected to the clamping frame; the clamping drive member is located outside the clamping space and connected to the clamping frame, and is connected to one of the two clamping members to drive the connected clamping member to move toward the other clamping member.

[0032] 200. Components. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0034] This disclosure provides a polishing apparatus, such as... Figure 1 As shown, the polishing device includes a fixed base 1, a polishing assembly 3, and at least a pair of guide assemblies 2. The polishing assembly 3 includes sandpaper 31 and two drive rollers 32. The two drive rollers 32 are arranged in parallel and are rotatably connected to the fixed base 1. The two ends of the sandpaper 31 in the length direction are respectively wound on the two drive rollers 32. The sandpaper 31 has a polishing surface for polishing the parts 200.

[0035] Figure 2 for Figure 1 The side view of the center guide component, combined with Figure 2 Each of at least one pair of guide components 2 is connected to the fixed base 1. Each pair of guide components 2 is symmetrically arranged on opposite sides of the sandpaper 31 in the width direction between the two drive spools 32, and each pair of guide components 2 is configured to bend the opposite sides of the sandpaper 31 in the width direction between the two drive spools 32 toward the opposite side of the sanding surface.

[0036] When the grinding device provided in this embodiment grinds the component 200 (shaft component), since the grinding device includes a fixed base 1 and at least one pair of guide components 2, and each guide component 2 is connected to the fixed base 1, the fixed base 1 can provide an installation base for the guide component 2.

[0037] Furthermore, since the polishing assembly 3 includes sandpaper 31 and two drive rollers 32, and the two ends of the sandpaper 31 in the length direction are respectively wound on the two drive rollers 32, when polishing the component 200, the drive rollers 32 can be controlled to rotate, thereby driving the sandpaper 31 to move. When the sandpaper 31 moves, it can polish the rotating component 200 placed above the sandpaper 31.

[0038] Meanwhile, since each pair of guide components 2 is symmetrically arranged on opposite sides of the width direction of the sandpaper 31 located between the two drive rollers 32, and each pair of guide components 2 is configured to bend the opposite sides of the width direction of the sandpaper 31 located between the two drive rollers 32 toward the opposite side of the grinding surface, by controlling the guide components 2, the two sides of the width direction of the sandpaper can be bent, ensuring that the edge of the sandpaper 31 will not affect the grinding effect of other parts of the component 200, reducing the situation of unqualified parts and reducing the defect rate.

[0039] The width direction of sandpaper 31 mentioned above refers to... Figure 1 Along the direction perpendicular to the paper surface, the sanding surface of sandpaper 31 refers to the sanding surface in... Figure 1 The side of the medium sandpaper 31 facing upwards. The two sides of the sandpaper 31 in the width direction that are bent towards the opposite side of the sanding surface refer to the two sides of the sandpaper 31 in the width direction facing... Figure 1 The bottom of the medium sandpaper 31 is bent.

[0040] Optionally, the guide assembly 2 includes a guide member 21 and a locking pin 23. The guide member 21 is hinged to the fixed base 1, and the axial direction of the hinge axis between the guide member 21 and the fixed base 1 is the same as the arrangement direction of the two drive rollers 32. The guide member 21 has a guide groove 210 for accommodating the side of the sandpaper. The opening of the guide groove 210 faces the side of the sandpaper 31 in the width direction. The locking pin 23 is connected to both the guide member 21 and the fixed base 1 to lock the guide member 21 to the fixed base 1, such that the angle between the opening direction of the guide groove 210 and the reference plane is an acute angle, and the reference plane is the plane containing the axes of the two drive rollers 32.

[0041] In the above implementation, by arranging guide grooves 210 in the guide member 21, both sides of the sandpaper 31 in the width direction can be accommodated in the guide grooves 210. Furthermore, since the guide member 21 is hinged to the fixed base 1, the guide member 21 can rotate relative to the fixed base 1. This allows for flexible arrangement of the position of the guide member 21 according to the curvature of the sandpaper 31, thus facilitating the placement of the sandpaper 31. The locking pin 23 is used to fix the guide member 21 relative to the fixed base 1 after it has been rotated to a suitable angle, preventing it from wobbling.

[0042] In this embodiment, the guide member 21 includes a U-shaped guide rail 211, a hinge block 212, and a locking block 213. A guide groove 210 is located within the guide rail 211; in other words, the opening of the guide rail 211 is the guide groove 210. The hinge block 212 is located outside the guide rail 211 and at the opening of the guide groove 210. The hinge block 212 is connected to the outer wall of the guide rail 211. The hinge block 212 is hinged to the fixed base 1. The locking block 213 is located outside the guide rail 211 and at the opening of the guide groove 210, and is connected to the hinge block 212. The locking block 213 has a threaded hole, and the locking pin 23 is a screw. One end of the locking pin 23 is threaded into the threaded hole, and the other end is inserted into the fixed base 1 to lock the locking block 213 onto the fixed base 1.

[0043] In other examples, the guide component 2 can also have other structures, such as a pull-down component. The pull-down component includes an elastic pull cord and a drive mechanism for extending and retracting the pull cord. The pull cord is connected to the edge of the sandpaper 31. This allows the two edges of the sandpaper 31 to bend downwards.

[0044] In this embodiment, there are two pairs of guide components 2. The two pairs of guide components 2 are displaced at intervals between the two drive rollers 32 along the length direction of the sandpaper 31. This can further improve the guiding effect of the guide components 2 on both sides of the sandpaper 31 in the width direction.

[0045] Additionally, to prevent tearing of the sandpaper 31 after it has fully expanded in the width direction, the spacing between the two drive rollers 32 can be adjusted. Simultaneously, the bending direction and winding direction of the sandpaper 31 can be made to be opposite to the sanding surface; for example, the bending direction of the sandpaper 31 in the width direction can be... Figure 2 The sandpaper 31 is bent downwards and, after sanding, is wound clockwise around the drive shaft 32.

[0046] Optionally, the guide assembly 2 also includes a guide wheel 24, which is located between two guide members 21 in the same pair of guide assemblies 2 and on the back side of the sandpaper 31. The back side and the grinding surface are opposite to the sandpaper 31. The guide wheel 24 is rotatably connected to the fixed base 1, and the outer periphery of the guide wheel 24 is in contact with the bend in the width direction of the sandpaper 31.

[0047] In the above implementation, the guide wheel 24 is used to support the bend of the sandpaper 31 so that the sanding surface of the sandpaper 31 is horizontal. At the same time, the guide wheel 24 can also guide the sandpaper 31 to prevent the sandpaper 31 from breaking at the bend, so that the edge of the sandpaper 31 can smoothly enter the guide groove 210.

[0048] In other examples, the guide wheel 24 can also be other structures, such as a roller, a rotating roller, etc.

[0049] See also Figure 1In this embodiment, the grinding assembly 3 further includes two winding motors 33, each corresponding to one of the two drive rollers 32. The winding motors 33 are connected to their respective drive rollers 32 and to the fixed base 1. In this way, the winding motors 33 can drive the corresponding drive rollers 32 to rotate.

[0050] See Figure 1 and Figure 2 Optionally, the mounting base 1 includes a base body 11, a lifting drive rod 12, and a lifting plate 13. The top of the base body 11 has a mounting groove 110 located between two drive rollers 32. The lifting drive rod 12 is located within the mounting groove 110, and one end of the lifting drive rod 12 is connected to the base body 11. The lifting drive rod 12 is capable of extending and retracting along a direction perpendicular to the sandpaper 31 located between the two drive rollers 32. The lifting plate 13 is located within the mounting groove 110, and the other end of the lifting drive rod 12 is connected to the side of the lifting plate 13 facing away from the sandpaper 31. The side of the lifting plate 13 facing the sandpaper 31 is connected to each guide assembly 2.

[0051] In the above implementation, the base 11 provides an installation foundation for the lifting drive rod 12, etc. The lifting drive rod 12 drives the lifting plate 13 to rise and fall, so that the lifting plate 13 can move up and down along with the guide member 21. During grinding, the guide member 21, driven by the lifting drive rod 12, moves upward toward the sandpaper 31 along with the lifting plate 13, thereby positioning the two edges of the sandpaper 31 within the guide groove 210. When not grinding, the guide member 21, driven by the lifting drive rod 12, can descend with the lifting plate 13, moving away from the sandpaper 31.

[0052] In other examples, the lifting drive rod 12 may not be provided, that is, the guide 21 always accommodates the two edges of the sandpaper 31.

[0053] In this embodiment, the base 11 is a rectangular block structure. The winding motor 33 and the drive shaft 32 are both connected to the top of the base 11. The lifting plate 13 is a flat plate structure. There are two lifting drive rods 12, which are arranged at intervals along the length of the sandpaper 31, and the fixed ends of each lifting drive rod 12 are fixed to the lifting plate 13 by bolts or other fasteners.

[0054] Optionally, the guide assembly 2 further includes a support plate 25 and a connecting plate 26. Along the extension and retraction direction of the lifting drive rod 12, one side of the support plate 25 is connected to the lifting plate 13, and the other side is hinged to the guide member 21. The support plate 25 is perpendicular to the lifting plate 13. Along the extension and retraction direction of the lifting drive rod 12, one side of the connecting plate 26 is connected to the support plate 25, and the other side is rotatably connected to the guide wheel 24.

[0055] In the above implementation, the support plate 25 provides a mounting base for the guide member 21 via the connecting plate 26, allowing the guide member 21 to rotate relative to the support plate 25. The connecting plate 26 provides a mounting base for the guide wheel 24, allowing the guide wheel 24 to support the sandpaper 31.

[0056] Figure 3 for Figure 1 Enlarged view at point A in the middle. Figure 4 for Figure 2 Enlarged view at point B, combined with Figure 3 and 4 The support plate 25 includes a first connecting plate 251, a second connecting plate 252, and a third connecting plate 253. The bottom of the first connecting plate 251 is vertically welded to the lifting plate 13. The top of the first connecting plate 251 has a hinge groove 250, and a hinge block 212 is located within the hinge groove 250. The second connecting plate 252 is located on a surface of the first connecting plate 251 facing the guide wheel 24, and the second connecting plate 252 is vertically connected to the first connecting plate 251 near its top. The third connecting plate 253 is connected to a surface of the second connecting plate 252 away from the bottom of the first connecting plate 251. The third connecting plate 253 is used to connect with the locking pin 23. The support plate 25 is vertically connected to a surface of the third connecting plate 253 away from the bottom of the first connecting plate 251.

[0057] Figure 5 for Figure 1 Enlarged view of the supporting components, combined with Figure 5 The grinding device also includes a support assembly 4, which is located in the mounting groove 110 and in the lifting plate 13. The support assembly 4 is connected to the lifting plate 13 and is configured to extend and retract in a direction perpendicular to the sandpaper 31 located between the two drive rollers 32 to contact the sandpaper 31.

[0058] In the above implementation, the support component 4 is used to lift the sandpaper 31 so that the sandpaper 31 can fit tightly against the sanding surface.

[0059] Optionally, the support assembly 4 includes two elastic support units 41, which are spaced apart in the mounting groove 110 along the arrangement direction of the two drive rollers 32.

[0060] The elastic support unit 41 includes a support rod 411, a first outer cylinder 412, and a first elastic element 413. One end of the support rod 411 is located on the side of the sandpaper 31 facing the lifting plate 13 and is in contact with the sandpaper 31. The second end of the support rod 411 slides inside the top of the first outer cylinder 412, and the bottom of the first outer cylinder 412 is connected to the lifting plate 13. The length direction of the support rod 411 is perpendicular to the sandpaper 31. The first elastic element 413 is located inside the first outer cylinder 412, and its two ends are clamped between the support rod 411 and the first outer cylinder 412.

[0061] In the above implementation, during the polishing process, after the lifting plate 13 is raised, the first outer cylinder 412 and the support rod 411 will rise together. In this way, the support rod 411 will push the sandpaper 31 to rise, so that the sandpaper 31 is in contact with the component 200, thereby increasing the contact area between the sandpaper and the component 200.

[0062] In this embodiment, to prevent the support rod 411 from moving out of the first outer cylinder 412, the support rod 411 is a T-shaped rod, with the larger end of the support rod 411 located inside the first outer cylinder 412. Similarly, to prevent the connecting rod 421 from moving out of the second outer cylinder 422, a limiting block is provided at the inner end of the connecting rod 421 located in the second outer cylinder 422. Both the first elastic element 413 and the second elastic element 423 are telescopic springs.

[0063] Optionally, the bottom of the first outer cylinder 412 in the elastic support unit 41 is slidably connected to the lifting plate 13, and the moving direction of the first outer cylinder 412 is the length direction of the sandpaper 31. The support assembly 4 also includes a connecting unit 42, which is located between the two elastic support units 41. The connecting unit 42 is connected to the two first outer cylinders 412 respectively to adjust the distance between the two first outer cylinders 412.

[0064] Thus, after the component 200 is clamped and ready for grinding, the two lifting drive rods 12 are activated, causing the lifting plate 13 to rise. This causes the support rods 411 in the two elastic support units 41 to push the sandpaper 31 up, bringing it into contact with the component. Since the two second outer cylinders 422 can move to both sides, and the connecting unit 42 can adjust the distance between the two first outer cylinders 412, the two support rods 411 can move synchronously and support various positions along the length of the sandpaper 31, ensuring maximum contact area between the sandpaper 31 and the component 200 and improving grinding efficiency. In other words, if the component is large, the corresponding sandpaper 31 has a large grinding surface. In this case, the sandpaper 31 located between the two drive rollers 32 is too long to ensure that the other components are fully in contact in real time. To ensure good contact between the grinding surface and the component, the connecting unit 42 can be controlled to allow the two elastic support units 41 to move along the length of the grinding surface to support different positions on the grinding surface.

[0065] Optionally, the connecting unit 42 includes a connecting rod 421, two second outer cylinders 422 and two second elastic elements 423. The bottom of the connecting rod 421 is connected to the fixed base 1, and the top of the connecting rod 421 has two ends, with the two ends of the top of the connecting rod 421 located inside the two second outer cylinders 422 respectively.

[0066] Two second outer cylinders 422 correspond one-to-one with two elastic support units 41. The end of each second outer cylinder 422 away from the connecting rod 421 is connected to the side wall of the first outer cylinder 412 in the corresponding elastic support unit 41. Two second elastic elements 423 correspond one-to-one with the two second outer cylinders 422. Each second elastic element 423 is located inside the corresponding second outer cylinder 422, and both ends of the second elastic element 423 are clamped between the bottom of the corresponding second outer cylinder 422 and the connecting rod 421 located inside the corresponding second outer cylinder 422.

[0067] When polishing component 200, the two lifting drive rods 12 are activated, causing the lifting plate 13 to rise. The rising support rod 411 then pushes the sandpaper 31 upward, allowing the sanding surface of the sandpaper 31 to contact the component. Since the bottom of the first outer cylinder 412 is slidably connected to the lifting plate 13, one of the first outer cylinders 412 can be manually pushed after the support rod 411 rises. The first outer cylinder 412 will then move along with the support rod 411, which can support the sandpaper 31 at different positions. As the first outer cylinder 412 moves, it also moves the second outer cylinder 422, which in turn compresses the second elastic element 423. When the first outer cylinder 412 is not subjected to external force, the second elastic element 423 will drive the second outer cylinder 422 to reset, thereby causing the first outer cylinder 412 to reset. This allows the support rod 411 to move back and forth, thereby maintaining the maximum contact area between the sandpaper 31 and the component 200, making the sanding work more efficient.

[0068] Optionally, the elastic support unit 41 further includes a slider 414 connected to the bottom of the first outer cylinder 412. The lifting plate 13 in the top of the fixed base 1 has two grooves 1310, which are spaced apart along the length of the sandpaper 31, and the length direction of each groove 1310 is the length direction of the sandpaper 31. The two grooves 1310 correspond one-to-one with the two sliders 414 in the two elastic support units 41, and each slider 414 is located in the corresponding groove 1310.

[0069] In the above implementation, the slider 414 is used to cooperate with the groove 1310 so that the movement of the first outer cylinder 412 can be along a straight line without deviating.

[0070] Figure 6 for Figure 1 Side view of the clamp-on component, combined with Figure 6 Optionally, the grinding device also includes a clamping assembly 5, which includes a clamping frame 51, two clamping parts 52 and a clamping drive part 53.

[0071] The clamping frame 51 is at least partially suspended on the top of the mounting base 1. The clamping frame 51 has a clamping space 510 for accommodating the component 200 on the side facing the mounting base 1. Two clamping members 52 are spaced apart within the clamping space 510 along the axis of the drive reel 32, and both clamping members 52 are connected to the clamping frame 51. A clamping drive member 53 is located outside the clamping space 510 and is connected to the clamping frame 51. The clamping drive member 53 is connected to one of the two clamping members 52 to drive the connected clamping member 52 toward the other clamping member 52.

[0072] In the above implementation, the clamping assembly 5 is used to clamp the component 200 onto the sandpaper 31 for polishing.

[0073] The clamping assembly 5 consists of a clamping frame 51, two clamping members 52, and a clamping drive member 53. The clamping frame 51 provides a mounting base for the clamping members 52 and the clamping drive member 53. The clamping members 52 are used to clamp both ends of the component 200. The clamping drive member 53 drives one of the clamping members 52 to move towards the other, thereby shortening the distance between the two clamping members 52 and clamping the component 200.

[0074] In other words, when clamping and fixing component 200, component 200 is placed between two clamping members 52, and then the clamping drive member 53 is controlled to drive one of the two clamping members 52 to move, so that component 200 can be clamped between the two clamping members 52.

[0075] Optionally, the clamping frame 51 includes a U-shaped frame 511 and an L-shaped connecting rod 512. The U-shaped frame 511 has an opening facing the fixed base 1, and the clamping space 510 is located within the U-shaped frame 511. The U-shaped frame 511 includes a first sidewall 5111 and a second sidewall 5112, which are located on opposite sides of the opening of the U-shaped frame 511. The L-shaped connecting rod 512 is connected to the first sidewall 5111 and forms a receiving space for the rotation drive member 54. The clamping drive member 53 is connected to the second sidewall 5112.

[0076] In the above implementation, the U-shaped frame 511 provides a mounting base for the component 200. The L-shaped connecting rod 512 forms a space with the U-shaped frame 511 to accommodate the rotary drive component 54.

[0077] In this embodiment, the clamping component 52 is a disc structure, which allows it to fit well with the two end faces of the component 200.

[0078] Optionally, the clamping drive component 53 includes a drive cylinder 531, a top plate 532, and a push rod 533. One end of the drive cylinder 531 is connected to the second side wall 5112, and the other end of the drive cylinder 531 is connected to the top plate 532. One end of the push rod 533 is perpendicularly connected to the top plate 532, and the other end of the push rod 533 passes through the second side wall 5112 and is connected to the other of the two clamping components 52.

[0079] In the above implementation, the drive cylinder 531 is telescopic. After the drive cylinder 531 telescopicates, it can move the top plate 532 toward or away from another clamping member 52. After the top plate 532 moves, it can move the push rod 533. After the push rod 533 moves, it can move the clamping member 52 connected to the push rod 533 together.

[0080] Optionally, the clamping assembly 5 further includes a rotary drive 54 located outside the clamping space 510, and the rotary drive 54 and the clamping drive 53 are respectively located on opposite sides of the clamping frame 51 along the arrangement direction of the two clamping members 52. The rotary drive 54 is connected to the clamping frame 51, and the rotary drive 54 and the clamping drive 53 are respectively connected to the two clamping members 52 in a one-to-one correspondence.

[0081] The rotary drive 54 is connected to one of the two clamping members 52, and the clamping drive 53 is connected to the other of the two clamping members 52. The rotary drive 54 is used to drive the corresponding clamping member 52 to rotate, and the direction of the rotation axis of the clamping member 52 connected to the rotary drive 54 is the arrangement direction of the two clamping members 52.

[0082] In the above implementation, the rotary drive 54 drives one of the clamping parts 52 to rotate, thereby causing the component 200 to rotate. The rotary drive 54 drives one of the clamping parts 52 to rotate, thus causing the component 200 to rotate. Compared to the traditional method of using a three-jaw chuck to clamp one end of the component 200, this clamping method effectively maintains a higher degree of coaxial rotation at both ends of the component 200, reducing the impact of vibration on grinding accuracy.

[0083] Optionally, the rotary drive component 54 includes a drive motor 541, a drive gear 542, a driven gear ring 543, and a rotating shaft 544. The drive motor 541 is connected to the L-shaped connecting rod 512, the drive gear 542 is connected to the output end of the drive motor 541, the driven gear ring 543 is located on one side of the drive gear 542 and meshes with the drive gear 542, the rotating shaft 544 is inserted into the driven gear ring 543, one end of the rotating shaft 544 is rotatably connected to the L-shaped connecting rod 512, and the other end of the rotating shaft 544 is slidably inserted into the first side wall 5111 and connected to one of the two clamping components 52.

[0084] In the above implementation, the drive motor 541 drives the drive gear 542 to rotate, which in turn drives the driven gear ring 543 to rotate. The driven gear ring 543 then drives the rotating shaft 544 to rotate. The rotating shaft 544 then drives one of the clamping parts 52 to rotate, which in turn drives the component 200 to rotate.

[0085] Optionally, the U-shaped frame 511 further includes a base plate 5113, which is connected between the first side wall 5111 and the second side wall 5112. The clamping frame 51 also includes a second electric telescopic rod 514, which is located between the U-shaped frame 511 and the fixed base 1. Both ends of the second electric telescopic rod 514 are connected to the base plate 5113 and the translation assembly 6 (described below), respectively. The telescopic direction of the second electric telescopic rod 514 is the same as the telescopic direction of the lifting drive rod 12.

[0086] In the above implementation, the second electric telescopic rod 514 can extend and retract, thereby raising and lowering the clamping frame 51, so that the component 200 connected in the clamping frame 51 can move toward or away from the sandpaper 31 to adjust the relative position between the component 200 and the sandpaper 31.

[0087] See you again Figure 1 Optionally, the grinding device also includes a translation component 6, which is located at the bottom of the fixed base 1 and is slidably connected to the bottom of the fixed base 1. The translation component 6 is configured to drive the fixed base 1 to move along the axial direction of the drive roller 32.

[0088] The arrangement of the translation component 6 allows the fixed base 1 to move along with the sandpaper 31, so that after the sandpaper 31 has polished one section of the component 200, it can be moved to polish the next section in the length direction.

[0089] Optionally, the translation assembly 6 includes a translation frame 60, a lead screw 61, a lead screw motor 62, and a connector 63.

[0090] The translation frame 60 includes a support base 601, a vertical plate 602, and a horizontal plate 603. The bottom of the support base 601 is used to place it on a workbench, and the top of the support base 601 is slidably connected to the fixed base 1. The vertical plate 602 is connected to the top of the support base 601 and defines a space for mounting the guide assembly 2 and the grinding assembly 3, etc. The horizontal plate 603 is located on the side of the vertical plate 602 away from the support base 601 and is connected to the vertical plate 602. The horizontal plate 603 is connected to the second electric telescopic rod 514 in the clamping assembly 5. In this way, the horizontal plate 603 provides a mounting base for the clamping assembly 5, allowing the clamping assembly 5 to be suspended above the sandpaper 31.

[0091] The lead screw 61 is connected to the support base 601, and one end of the lead screw 61 is connected to the output end of the lead screw motor 62. The lead screw motor 62 is connected to the side wall of the support base 601. The length direction of the lead screw 61 is the same as the width direction of the sandpaper 31 and the length direction of the part to be sanded. The connector 63 is fitted over the lead screw 61 and threadedly connected to the lead screw 61. The connector 63 is connected to the fixed base 1.

[0092] In this way, the lead screw motor 62 drives the lead screw 61 to rotate. After the lead screw 61 rotates, it can drive the connecting part 63 to move along the length direction of the lead screw 61. After the connecting part 63 moves, it can move the fixed seat 1. In this way, the fixed seat 1 can move the sandpaper 31, so that after sanding one section of the part 200, the sandpaper 31 can move and sand the other section, so that the longer sanding area of ​​the part 200 can be sanded with the narrower sandpaper 31.

[0093] The following is combined Figure 6 Here is a brief introduction to the working process of the above grinding device:

[0094] Combination Figure 6 First, the component 200 is placed between two clamping members 52. The drive cylinder 531 is then extended and retracted, causing the top plate 532 to move towards the other clamping member 52. After the top plate 532 moves, it can move the push rod 533. After the push rod 533 moves, it can move the clamping member 52 connected to the push rod 533 together, so that both ends of the component 200 are clamped and fixed by the two clamping members 52 respectively. The second electric telescopic rod 514 is then extended, so that after the component 200 moves down, it can fit against the sandpaper 31. At the same time, the two edges of the sandpaper 31 are positioned in the guide groove 210.

[0095] Then, the control support assembly 4 supports the sandpaper 31. Activating the two lifting drive rods 12 causes the lifting plate 13 to rise, which in turn causes the two support rods 411 to push the sandpaper 31 upwards, bringing it into contact with the component. This also pushes the two first outer cylinders 412 to move to both sides, increasing the contact area between the sandpaper 31 and the component 200, making the sanding work more efficient.

[0096] Next, the rotation of component 200 and the movement of sandpaper 31 are controlled. The drive motor 541 is started, driving the drive gear 542 to rotate. The rotation of the drive gear 542 then drives the driven gear ring 543 to rotate. The rotation of the driven gear ring 543 causes the rotating shaft 544 to rotate. The rotation of the rotating shaft 544 causes one of the clamping components 52 to rotate, which in turn causes component 200 to rotate. The rotation of the drive roller 32 is controlled, allowing the sandpaper 31 to move.

[0097] After grinding one section of the component 200 along its length, the lead screw motor 62 is started. After the lead screw 61 rotates, it drives the connecting piece 63 to move along the length of the lead screw 61. After the connecting piece 63 moves, it can move the fixed seat 1. In this way, the fixed seat 1 can move the sandpaper 31, etc., so that the sandpaper 31 can grind the next section of the component 200.

[0098] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
