Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a device for processing a stabilizing bar bushing for an automobile chassis. Background Art

[0002] The stabilizer bar bushing connects the stabilizer bar and provides effective support during the operation of the stabilizer bar, as well as plays the role of vibration isolation and noise reduction. The reasonable coordination between the stabilizer bar and the bushing is directly related to whether the bushing will generate noise and abnormal wear. Bushings are almost all rubber products, and their production cannot be separated from the auxiliary production of production molds.

[0003] A Chinese patent with the authorization announcement number CN217144789U discloses a mold for processing stabilizer bar bushings, including a mold, a first water chamber and a spring. Several groups of condensing tubes are fixedly connected to the edge of the mold, and the condensing tubes extend through the inside of the mold to the outside. The end face of the mold is connected with the first water chamber, and the first water chamber is annular. Several groups of water holes are opened on the side of the first water chamber. In the patent document, the water inside the second water chamber flows to the inside of the first water chamber through the condensing tube, flows to the inside of the annular water tank through the water hole, and then flows out from the water outlet, so that there is flowing cold water in the whole process, which quickly cools the inside of the mold, so that the bushing inside the mold is quickly cooled and formed. After the bushing is processed and formed, the pressure plate is released, and the rebound force of the spring drives the slide bar to slide inside the slide hole, so that the bottom plate slides to eject the formed bushing from the inside of the mold, which is convenient for production workers to remove the bushing and improves production efficiency.

[0004] After the existing chassis stabilizer bar bushings are processed and formed, the formed bushings need to be polished to improve the smoothness of the outer surface of the material, which is beneficial to ensure the manufacturing quality of the finished bushings. However, when grinding the bushings, the existing stabilizer bar bushing processing device can only simply grind the outer wall of the bushing on the forming device, and cannot effectively grind the top surface, bottom surface and curved surface of the bushing. The subsequent processes also need to trim the top and bottom surfaces of the bushing, which greatly increases the workload of the workers, and manual trimming cannot well ensure the uniformity of the quality of the finished bushings. Summary of the invention

[0005] The present invention provides a processing device for a chassis stabilizer bar bushing of an automobile, aiming to solve the problem in the related art that after the existing chassis stabilizer bar bushing is processed and formed, the formed bushing needs to be polished, so as to improve the smoothness of the outer surface of the material, which is beneficial to ensure the manufacturing quality of the finished bushing. However, when polishing the bushing, the existing stabilizer bar bushing processing device can only simply polish the outer wall of the bushing on the forming device, and cannot effectively polish the top surface, bottom surface and curved surface of the bushing. The top surface and bottom surface of the bushing need to be trimmed in the subsequent process, which greatly increases the workload of the workers, and the manual trimming cannot well ensure the uniformity of the quality of the finished bushing.

[0006] The present invention provides a processing device for a bushing of a stabilizer bar of an automobile chassis, comprising: a shell, a mold and a grinding wheel. The mold is divided into two parts, both of which are slidably mounted on the shell. A push rod can be mounted on the shell in a lifting manner. A driving assembly is arranged on the push rod. The push rod can push the bushing to rise and drive the mold to open. A mounting frame is mounted on the shell in a horizontal sliding manner. The grinding wheel is mounted on the mounting frame. The lifting frame can be lifted and mounted on the shell. A driving disk is rotatably mounted on the lifting frame. A plurality of guide grooves are arranged at the bottom of the driving disk. A swivel seat is also rotatably mounted on the lifting frame. A plurality of clamping members are radially slidably mounted on the swivel seat. The clamping members are slidably matched with the guide grooves. The clamping members can clamp the bushing and drive it to rise and fall. A driving plate is fixedly mounted on the lifting frame. The driving plate has a first section, a second section, a third section and a fourth section. The driving plate can push the mounting frame to slide horizontally. The first section contacts the mounting frame and can grind the upper inclined surface of the bushing. The third section contacts the mounting frame and can grind the peripheral wall of the bushing. The fourth section contacts the mounting frame and can grind the upper and lower end surfaces and the lower inclined surface of the bushing.

[0007] Beneficial effect: when the cooling of the bushing is completed, the telescopic part drives the push rod to rise, and at the same time, the two molds are driven to move to both sides and open through the driving assembly, and the push rod pushes the formed bushing upward to completely separate it from the mold. After the bushing is raised to the top, its upper surface is flush with the lower end surface of the grinding wheel, and then the lifting frame descends, and the driving plate contacts the mounting frame to make it slide horizontally to one side. During the sliding process, the grinding wheel contacts the upper surface of the bushing to complete the grinding of the top of the bushing. As the lifting frame descends, the clamping part extends into the inner side of the bushing, and then the driving disk rotates, so that the clamping part moves outward along the radial direction of the swivel seat at the same time to clamp the bushing, and then the lifting frame drives the bushing to start rising, and at the same time, the swivel seat and the clamping part rotate synchronously, driving the bushing to rotate. When the lifting frame is raised, the inclined surface and the plane on the driving plate will control the horizontal movement distance of the grinding wheel, thereby realizing the overall grinding of the bushing from top to bottom in sequence.

[0008] Preferably, the driving assembly includes a first connecting rod rotatably mounted on the push rod, the first connecting rod is symmetrically arranged on both sides of the push rod, the other end of the first connecting rod is rotatably connected to the mold on that side, a bottom plate is rotatably mounted near the upper end of the push rod, a pin is arranged in the middle of the bottom plate, the pin divides the bottom plate into two parts, both parts on the bottom plate can rotate around the pin, and second connecting rods are rotatably mounted on both sides of the bottom of the bottom plate, movable grooves are opened on the first connecting rod and the second connecting rod, and a rotating shaft is fixedly arranged in the movable groove of the first connecting rod, the second connecting rod passes through the movable groove on the first connecting rod, and the rotating shaft is located in the movable groove of the second connecting rod.

[0009] The effect is that when the ejector pushes the bushing up, the mold can be pushed open at the same time to facilitate material removal, and the bottom plate is bent downward and separated from the bottom of the bushing to prevent the bottom from being pulled and damaged when the bushing is pushed upward.

[0010] Preferably, the guide grooves are all arc-shaped structures, a plurality of slideways are provided on the swivel seat, and moving blocks are slidably installed in the slideways, protrusions are provided on the upper end surfaces of the moving blocks, and the protrusions are respectively located in the guide grooves, and the clamping parts are respectively fixedly installed on the moving blocks.

[0011] The effect is that when the guide groove rotates, the protrusion is forced to move in the guide groove, driving the four moving blocks to move along the slide at the same time. The four moving blocks drive the clamping parts along the radial direction of the swivel seat, and at the same time approach or move away from the center direction of the swivel seat, so as to facilitate clamping the bushing. After the protrusion moves to the end of the guide groove, the protrusion and the moving block have no moving space, so the driving disk can drive the swivel seat to rotate together, so that the clamping parts drive the bushing to rotate synchronously.

[0012] Preferably, the first section and the third section are both vertical planes, the planes where the two sections are located are parallel to each other and there is a certain distance between them, the second section is an inclined plane, and the two ends are respectively connected to the first section and the third section, and the fourth section is also inclined.

[0013] The effect is that when the driving plate descends, the mounting frame can be driven to slide horizontally, and the bushing can be fully polished in coordination with the lifting and lowering of the bushing.

[0014] Preferably, a sliding column is fixedly provided on the mounting frame, the sliding column is slidably matched with the side wall of the shell, and a spring is sleeved on the sliding column. The grinding wheel is rotatably mounted on the mounting frame, and the mounting frame has a contact part. When the driving plate is lifted or lowered, it will conflict with the contact part, forcing the mounting frame to slide horizontally.

[0015] Preferably, a lead screw is rotatably installed on the upper surface of the lifting frame, a lead screw sleeve is rotatably installed on the top of the shell, the lead screw passes through the lead screw sleeve and is threadedly matched with the lead screw sleeve, a groove is provided along the axial direction of the lead screw, a protrusion that slides with the groove is provided on the inner wall of the lead screw sleeve, a first gear is fixedly installed on the outside of the lead screw sleeve, and a second gear that meshes with the first gear is rotatably installed on the top of the shell, and the second gear is driven by a motor.

[0016] Preferably, the clamping members are columnar structures, and four of them are provided.

[0017] Preferably, a fixing seat is fixedly mounted on the upper end of the push rod.

[0018] The effect is that the fixing seat can be inserted into the metal tube of the bushing and can fix the bushing.

[0019] The above technical scheme is adopted, and the beneficial effects of the present invention are as follows: when the cooling of the bushing is completed, the push rod pushes the formed bushing upward to completely separate it from the mold. After the bushing is raised to the top, its upper surface is flush with the lower end surface of the grinding wheel, and then the lifting frame descends, and the driving plate contacts with the mounting frame to make it slide horizontally to one side. During the sliding process, the grinding wheel contacts the upper surface of the bushing to complete the grinding of the top of the bushing. As the lifting frame descends, the clamping piece extends into the inner side of the bushing, and then the driving disk rotates, and the clamping piece moves outward along the radial direction of the swivel seat at the same time to clamp the bushing. Then the lifting frame drives the bushing to rise, and at the same time, the swivel seat and the clamping piece drive the bushing to rotate. When the lifting frame is raised, the inclined surface and the plane on the driving plate will control the horizontal movement distance of the grinding wheel, thereby realizing the overall grinding of the bushing from top to bottom in turn, and can perform comprehensive grinding of the upper and lower arc surfaces and upper and lower end surfaces of the bushing after the bushing is formed, effectively saving manpower and ensuring production quality.

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 8 As shown, a specific embodiment of the present invention for a processing device for a chassis stabilizer bar bushing of an automobile includes a housing 10, a workbench 11, a mold 13, a push rod 20, a drive assembly, a telescopic member 14, a mounting frame 30, a grinding wheel 34, a lifting frame 40, a drive disc 50, a swivel seat 52, a clamping member 55 and a drive plate 60.

[0032] The workbench 11 is horizontally arranged near the bottom of the shell 10. The mold 13 is composed of two semicircular structures and is slidably installed on the workbench 11. A telescopic member 14 is installed below the workbench 11. The telescopic part of the telescopic member 14 is fixedly installed with a push rod 20, and the push rod 20 is connected to the mold 13 through a driving assembly.

[0033] When the telescopic member 14 drives the ejector rod 20 to rise, the two molds 13 are driven to move to both sides and open through the driving assembly, and at the same time, the formed bushing is pushed upward to separate it from the mold 13.

[0034] The mounting frame 30 is horizontally slidably mounted on the housing 10 , and a grinding wheel 34 is rotatably mounted on the mounting frame 30 to grind the bushing.

[0035] The lifting frame 40 is vertically slidably installed on the inner side of the shell 10, the driving disk 50 is rotatably installed on the lifting frame 40, and the swivel seat 52 is rotatably installed on the lower surface of the driving disk 50. At the same time, the swivel seat 52 and the lifting frame 40 also rotate and cooperate. There are multiple clamping members 55, which are all slidably installed on the swivel seat 52 and can slide along the radial direction of the swivel seat 52. When the driving disk 50 rotates, all the clamping members 55 can be caused to move synchronously first. After the clamping members 55 move to the extreme position, they will rotate together with the swivel seat 52.

[0036] The driving plate 60 is mounted on the lifting frame 40 . The driving plate 60 has a plurality of inclined surfaces and planes. When the lifting frame 40 drives the driving plate 60 to rise and fall, the driving plate 60 contacts the mounting frame 30 , and can push the mounting frame 30 to slide horizontally, thereby driving the grinding wheel 34 to move horizontally.

[0037] During operation, the material is first added into the mold 13 for injection molding. When the bushing is cooled, the telescopic member 14 drives the ejector rod 20 to rise. At the same time, the two molds 13 are driven to move to both sides and open through the driving assembly. The ejector rod 20 pushes the formed bushing upward to completely separate it from the mold 13. After the bushing is raised to the top, its upper surface is flush with the lower end surface of the grinding wheel 34. Then the lifting frame 40 descends, and the driving plate 60 contacts the mounting frame 30 to make it slide horizontally to one side. During the sliding process, the grinding wheel 34 and the upper surface of the bushing The top of the bushing is contacted and the grinding of the bushing is completed. As the lifting frame 40 descends, the clamping piece 55 extends into the inner side of the bushing, and then the driving disk 50 rotates, so that the clamping piece 55 moves radially outward along the rotating seat 52 at the same time to clamp the bushing. Then the lifting frame 40 drives the bushing to start rising. At the same time, the rotating seat 52 and the clamping piece 55 rotate synchronously, driving the bushing to rotate. When the lifting frame 40 is rising, the inclined surface and the plane on the driving plate 60 will control the horizontal movement distance of the grinding wheel 34, thereby realizing the overall grinding of the bushing from top to bottom in turn.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the workbench 11 is fixedly installed on the inner side of the shell 10, and two first slide rails 12 are arranged on the workbench 11 at intervals. The mold 13 is composed of two semicircular structures, and the bottoms of the two molds 13 are slidably matched with the first slide rails 12.

[0039] After the two molds 13 are closed, injection molding begins. This process belongs to the prior art, and its structure and working principle are not described in detail.

[0040] A telescopic part 14 is fixedly installed on the inner bottom of the shell 10. In this embodiment, the telescopic part 14 is a cylinder, and the telescopic part of the cylinder is fixedly connected to the push rod 20. The push rod 20 is arranged vertically, and a fixed seat 21 is provided at the upper end of the push rod 20. During the injection molding process, the fixed seat 21 is located on the inner side of the mold 13, and after injection molding, the fixed seat 21 will be inserted into the inner side of the bushing.

[0041] It is particularly noted that the middle of the bushing is a metal pipe, the fixing seat 21 is inserted into the pipe to play a fixing role, and the top and bottom of the bushing are both arc-shaped structures (such as Figure 1 and Figure 2 ).

[0042] The top rod 20 is rotatably mounted with a bottom plate 22 near the upper end. The bottom plate 22 is annular and has a pin in the middle. The pin divides it into two parts. Both parts of the bottom plate 22 can rotate around the pin. That is, the bottom plate 22 can be folded into a V-shaped structure (such as Figure 6 As shown in FIG. 1 ), the push rod 20 passes through the center of the bottom plate 22, and the pin is rotatably connected to the push rod 20.

[0043] The driving assembly includes a first connecting rod 23 rotatably mounted on the push rod 20, and the first connecting rod 23 is symmetrically arranged on both sides of the push rod 20. The other ends of the first connecting rod 23 are rotatably connected to the mold 13 on that side. The bottom of the bottom plate 22 is located on both sides of the push rod 20 and second connecting rods 25 are rotatably mounted. A movable groove 26 is opened on the first connecting rod 23 and the second connecting rod 25, and a rotating shaft 24 is fixedly arranged in the movable groove 26 of the first connecting rod 23. The second connecting rod 25 passes through the movable groove 26 on the first connecting rod 23, and the rotating shaft 24 is located in the movable groove 26 of the second connecting rod 25.

[0044] When the telescopic member 14 drives the ejector rod 20 to rise, the angle between the two first connecting rods 23 becomes larger, and the ends thereof away from the ejector rod 20 push the molds 13 on both sides to slide to both sides, so that the molds 13 are in an open state.

[0045] The upper end of the push rod 20 pushes the bottom plate 22 to rise continuously, and at the same time, it will also lift the second connecting rod 25. However, the first connecting rod 23 is restricted by the mold 13 and can only rotate, but the height of its upper end will not change. Therefore, during the rising process of the second connecting rod 25, the rotating shaft 24 will move in the moving groove 26 on the second connecting rod 25 until the rotating shaft 24 moves to the limit position of the moving groove 26 on the second connecting rod 25. The push rod 20 continues to rise, and the second connecting rod 25 cannot continue to rise, which will cause the upper end of the second connecting rod 25 to pull the bottom plate 22 to rotate, that is, the two parts of the bottom plate 22 rotate downward, that is, the angle on the bottom plate 22 is facing downward (such as Figure 6 as shown).

[0046] The purpose of rotating the bottom plate 22 is to separate the formed bushing from the bottom plate 22 to prevent the bottom of the bushing from being pulled when the bushing is subsequently driven upward by the clamping member 55 .

[0047] After the push rod 20 drives the formed bushing to rise to the highest point, the top of the bushing and the lower end surface of the grinding wheel 34 are at the same horizontal plane (such as Figure 6 As shown), the grinding wheel 34 is located on the right side of the bushing, so that the top of the bushing can be ground during the subsequent translation of the grinding wheel 34 to the left.

[0048] Continue back Figure 1 The mounting frame 30 is horizontally slidably mounted on the side wall of the shell 10, and a sliding column 31 is fixedly arranged on the mounting frame 30. The sliding column 31 also slides with the side wall of the shell 10, and a spring 32 is sleeved on the sliding column 31. The spring 32 can ensure that the mounting frame 30 is reset after moving. A connecting plate 33 is provided on the mounting frame 30, and a grinding wheel 34 is rotatably mounted on the connecting plate 33.

[0049] The mounting frame 30 has a contact portion 35 . When the driving plate 60 descends, it will contact the contact portion 35 on the mounting frame 30 , thereby forcing the mounting frame 30 to slide horizontally, thereby achieving the effect of horizontal movement of the grinding wheel 34 .

[0050] Second slide rails 41 are fixedly installed on the left and right side walls inside the shell 10, and the second slide rails 41 are arranged vertically. The lifting frame 40 is slidably installed on the second slide rails 41, and a lead screw 42 is rotatably installed on the upper surface of the lifting frame 40, and the upper end of the lead screw 42 extends to the top of the shell 10. A lead screw sleeve 45 is rotatably installed on the top of the shell 10, and the lead screw 42 penetrates the lead screw sleeve 45 and is threadedly matched with the lead screw sleeve 45. The lead screw 42 is provided with a groove along its axial direction, and a protrusion (not shown in the figure) that slidably matches the groove is provided on the inner wall of the lead screw sleeve 45, so that when the lead screw sleeve 45 rotates, it can not only drive the lead screw 42 to rotate, but also the lead screw 42 can be lifted and lowered along the lead screw sleeve 45.

[0051] A first gear 43 is fixedly installed on the outside of the screw sleeve 45, and a second gear 44 meshing with the first gear 43 is rotatably installed on the top of the shell 10. The second gear 44 is driven by a motor installed on the shell 10, so that the rotation of the two gears drives the rotation, so that the screw 42 drives the lifting frame 40 to rise and fall.

[0052] like Figure 2 , Figure 4 and Figure 5As shown, a driving disk 50 is rotatably mounted on the center of the lifting frame 40, and four arc-shaped guide grooves 51 are evenly opened on the lower surface of the driving disk 50 along its circumference. A rotating seat 52 is rotatably mounted on the lifting frame 40. At the same time, the upper surface of the rotating seat 52 is slidably matched with the lower surface of the driving disk 50. Four slideways are evenly opened on the upper surface of the rotating seat 52, each slideway is arranged along the radial direction of the rotating seat 52, and the slideways are arranged perpendicular to each other. A moving block 53 is slidably mounted in each slideway, and a convex groove is arranged on the upper end surface of the moving block 53. The protrusions 54 are respectively located in the guide grooves 51, so that when the guide grooves 51 rotate, the protrusions 54 are forced to move in the guide grooves 51, driving the four moving blocks 53 to move along the slideway at the same time. The four moving blocks 53 will move along the radial direction of the rotating seat 52 and approach or move away from the center direction of the rotating seat 52 at the same time. When the protrusions 54 move to the end of the guide grooves 51, the protrusions 54 and the moving blocks 53 have no moving space. Therefore, at this time, the driving disk 50 drives the rotating seat 52 to rotate together.

[0053] A through hole is provided in the center of the swivel seat 52, and a clamping member 55 is provided on the lower surface of the moving block 53. In the present embodiment, the clamping member 55 is a cylindrical structure. The four clamping members 55 pass through the through hole at the center of the swivel seat 52 and extend to the bottom of the swivel seat 52. Therefore, when the four clamping members 55 are in a close state, they can be lowered to extend into the metal tube in the middle of the bushing. Then, when the four clamping members 55 move radially along the swivel seat 52 at the same time and open outward, the four clamping members 55 can simultaneously abut against the inner wall of the metal tube to clamp and fix the bushing, making it easier to lift the bushing. When the swivel seat 52 rotates, the clamping members 55 will drive the bushing to rotate together. How to lift and rotate the bushing to achieve grinding will be described in detail later.

[0054] A third gear 56 is fixedly mounted on the outer side of the driving disk 50 , and a fourth gear 57 meshing with the third gear 56 is rotatably mounted on the lifting frame 40 . The fourth gear 57 is driven by a motor, thereby driving the driving disk 50 to rotate.

[0055] It is particularly emphasized that, in the present embodiment, the number of the clamping members 55 is 4, and in other modified embodiments, the number may be 2, 3 or even more.

[0056] like Figure 2As shown, a driving plate 60 is fixedly installed on the lower surface of the lifting frame 40. The driving plate 60 is arranged vertically, and the driving plate 60 corresponds to the position of the mounting frame 30 below. After the contact surface on the driving plate 60 contacts the contact portion 35 on the mounting frame 30, the mounting frame 30 can be driven to slide horizontally. The contact surface on the driving plate 60 is curved, and its contact surface is divided into a first section 61, a second section 62, a third section 63 and a fourth section 64 from top to bottom, wherein the first section 61 and the third section 63 are both vertical planes, and the surfaces where the two sections are located are parallel to each other and have a certain distance between them. The second section 62 is an inclined surface, and the two ends are respectively connected to the first section 61 and the third section 63, that is, the second section 62 connects the first section 61 and the third section 63 together, so that the mounting frame 30 can move between the first section 61 and the third section 63. The fourth section 64 is also inclined, and one end is connected to the third section 63.

[0057] When the lifting frame 40 drives the driving plate 60 to descend, its fourth section 64 first contacts with the contact portion 35 on the mounting frame 30, thereby pushing the mounting frame 30 to move horizontally to the left. At this time, it has been explained above that the top of the bushing and the lower end surface of the grinding wheel 34 are on the same horizontal plane, so when the mounting frame 30 moves horizontally to the left, the rotating grinding wheel 34 grinds the top position of the bushing.

[0058] Then, as the driving plate 60 continues to descend, the contact portion 35 on the mounting frame 30 passes through the third section 63, the second section 62 and finally the first section 61 in sequence, and the contact portion 35 contacts the plane of the first section 61. At this time, the four clamping members 55 extend into the metal tube in the middle of the bushing, and then when the four clamping members 55 simultaneously move radially along the rotating seat 52 to open outward, the four clamping members 55 can simultaneously contact the inner wall of the metal tube to clamp and fix the bushing.

[0059] In this state, the grinding wheel 34 is located directly above the left arc-shaped inclined surface on the bushing, and then the lifting frame 40 drives the driving plate 60 to start rising. At the same time, the clamping member 55 starts to drive the bushing to rotate. As the first section 61 rises, the contact portion 35 will interfere with the first section 61 near the lower end, and then the lifting frame 40 temporarily stops lifting. At this time, the grinding wheel 34 contacts the left arc-shaped inclined surface at the top of the bushing, and the grinding wheel 34 grinds the rotating bushing until the grinding of the arc-shaped surface at the top of the bushing is completed.

[0060] Then the driving plate 60 continues to rise, and the contact portion 35 passes through the second section 62 and enters the third section 63 (such as Figure 7As shown), the mounting frame 30 and the grinding wheel 34 continue to be pushed to move horizontally to the left. As the lifting frame 40 rises, the bushing is also lifted up. At this time, the outer peripheral wall of the bushing just contacts with the grinding wheel 34. As the third section 63 rises, the bushing also rises as the contact portion 35 reaches the lower end of the third section 63. In other words, the grinding wheel 34 passes through the entire outer peripheral wall of the bushing, thereby completing the grinding of the outer peripheral wall of the bushing.

[0061] The driving plate 60 continues to rise, and the contact portion 35 of the mounting bracket 30 reaches the fourth section 64 (eg Figure 8 As shown in the figure, since the fourth section 64 is inclined, as the fourth section 64 rises, the mounting frame 30 starts to move to the right. At this time, the grinding wheel 34 will just contact the arc surface of the bottom of the bushing, and then the lifting frame 40 temporarily stops rising to grind the arc surface of the bottom of the bushing.

[0062] After the arc surface at the bottom of the bushing is polished, the lifting frame 40 continues to drive the driving plate 60 to rise, and the mounting frame 30 continues to move horizontally to the right along the fourth section 64. As the bushing rises, the upper end surface of the grinding wheel 34 will contact the lower end surface of the bushing, thereby completing the polishing of the lower end surface of the bushing.

[0063] Therefore, when the bushing is raised, the mounting frame 30 contacts the first section 61, the second section 62, the third section 63 and the fourth section 64 on the driving plate 60, and the mounting frame 30 moves horizontally and contacts different positions on the bushing, thereby completing the comprehensive grinding of the bushing.

[0064] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
