DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figure 1 and Figure 2 As shown, a fine processing device for processing automobile parts includes an operating table 1 and a protective cover 11 for protecting various structures. An auxiliary component 4 for assisting in fixing and grinding a workpiece is provided in the middle of the upper end of the operating table 1. A chamfering component 2 for chamfering the workpiece is provided on the left side of the upper end of the operating table 1 in front of the auxiliary component 4. A cleaning component 6 and an extrusion component 5 are provided on the left side of the upper end of the operating table 1 for cooperating with each other to clean the surface of the workpiece after chamfering. A grinding component 3 is also provided on the right side of the upper end of the operating table 1 for cooperating with the auxiliary component 4 to grind the outer surface and an inclined end face of the workpiece.

[0036] In some embodiments of the present invention, Figure 3 and Figure 4The chamfering assembly 2 includes a hydraulic cylinder 21 and a guide rail 22 fixedly mounted on the upper end of the operating table 1. An L-shaped seat 23 is fixedly mounted on the output end of the hydraulic cylinder 21. The front end of the L-shaped seat 23 is slidably connected to the guide rail 22, so that the guide rail 22 can limit the L-shaped seat 23. A round seat 24 is fixedly mounted on the rear end of the vertical portion of the L-shaped seat 23. A horizontal groove 241 and a vertical groove 242 are provided at the rear end of the round seat 24. The horizontal groove 241 and the horizontal groove 241 are perpendicular to each other and the intersection is located at the rear end of the round seat 24. At the midpoint, a protrusion 26 is slidably installed on the inner surface of the vertical groove 242, and a protrusion 27 is slidably installed on the inner surface of the horizontal groove 241. The protrusion 26 and the protrusion 27 are rotatably connected to a rotating rod 28 for fixing the chamfering structure. The upper side of the rear end of the rotating rod 28 is fixedly connected to a chamfering machine 1 281 and a chamfering machine 2 282 for chamfering. The lower end of the protrusion 26 is fixedly installed with a hydraulic cylinder 25. An electric telescopic rod 29 is symmetrically arranged at the rear end of the vertical part of the L-shaped seat 23 at the same height as the horizontal groove 241.

[0037] It should be clarified that the depth of the above-mentioned vertical groove 242 is greater than the depth of the horizontal groove 1 241. When the output end of the hydraulic cylinder 25 pushes the protrusion 1 26 to move, it will not contact the lower end of the protrusion 2 27. Similarly, the left and right lengths of the protrusion 27 are greater than the width of the vertical groove 242. During use, the protrusion 27 always slides on the inner surface of the horizontal groove 1 241 and will not contact the inner surface of the horizontal groove 1 241.

[0038] like Figure 4 After the workpiece is fixed by the auxiliary component 4, the hydraulic cylinder 25 drives the protrusion 1 26 and then cooperates with the protrusion 2 27 to rotate the rotating rod 28. During the rotation of the rotating rod 28, the chamfering machine 1 281 and the chamfering machine 2 282 are respectively activated to chamfer the inclined surface of the front end of the workpiece.

[0039] It should be noted that the above-mentioned chamfering machine 1 281 and chamfering machine 2 282 are both mature technologies in the existing technology. When the chamfering machine 1 281 and the chamfering machine 2 282 are respectively activated, they are respectively driven by the rotating rod 28 to make elliptical movements along the beveled surface of the front end of the workpiece, thereby chamfering the outer surface and inner surface of the workpiece respectively.

[0040] A sliding roller 211 is fixedly connected to one side of the outer surface of the hydraulic cylinder 21 close to the L-shaped seat 23.

[0041] like Figure 5 and Figure 6The cleaning component 6 includes a second roller 61 rotatably connected to the upper end of the operating table 1, and an L-shaped rod 62 is fixedly connected to the upper side of the outer surface of the second roller 61, and a limiting groove 621 is provided on the front side of the upper end of the L-shaped rod 62, which is slidably connected to the outer surface of the sliding roller 211. A limiting groove 2 622 is provided on the rear side of the upper end of the L-shaped rod 62, and a sliding roller 66 is slidably connected to the inner surface of the limiting groove 2 622, and a limiting groove 3 63 is slidably connected to the upper part of the outer surface of the sliding roller 66 for limiting it. The lower end of the limiting groove 3 63 is fixedly connected to the upper end of the operating table 1, and the upper end of the sliding roller 66 is fixedly connected to the L-shaped plate 64.

[0042] like Figure 6 A sliding groove 641 is provided on the horizontal part of the upper end of the L-shaped plate 64, and a sliding roller 3 651 is slidably connected to the inner surface of the sliding groove 641. A fixed block 65 is fixedly connected to the middle part of the outer surface of the sliding roller 3 651, and a dial plate 652 for adjusting the position of the sliding roller 3 651 is fixedly connected to the right end of the fixed block 65. A plurality of springs 642 are fixedly connected to the rear end of the fixed block 65 and the front end of the vertical part of the L-shaped plate 64. The upper end of the sliding roller 3 651 is fixedly connected to an arc plate 67, and a wiping cloth 68 is fixedly connected to the inner arc surface of the arc plate 67.

[0043] After chamfering by chamfering machine 1 281 and chamfering machine 2 282 is completed, the L-shaped rod 62 cooperates with the sliding roller 1 211 to drive the L-shaped plate 64 and the fixed block 65 to move when the chamfering machine 2 282 and chamfering machine 1 281 are reset, and then the outer surface of the polished workpiece is cleaned by the wiping cloth 68.

[0044] In some embodiments of the present invention, Figure 7 The extrusion assembly 5 includes a rotating plate 51 fixedly connected to the lower side of the outer surface of the second roller 61, and the extrusion assembly 5 also includes a fixed plate 52 fixedly installed on the upper end of the operating table 1. An airbag 53 is fixedly connected between the rotating plate 51 and the fixed plate 52. A hose 54 is provided on the lower side of the outer surface of the airbag 53, and a one-way valve is provided at the connection between the airbag 53 and the hose 54. One side of the outer surface of the airbag 53 is connected to the cleaning liquid storage tank through another one-way valve, and the end of the hose 54 away from the airbag 53 is fixedly connected to the outer arc surface of the wiping cloth 68 through an arc plate 67.

[0045] It should be noted that the cleaning liquid mentioned above is a conventional design in the prior art, including but not limited to isopropyl alcohol solution, which only needs to satisfy the requirement that the solution block is adsorbed by the wiping cloth 68 and can achieve the effect of cleaning the surface of the polished workpiece.

[0046] In addition, through the one-way valve between the airbag 53 and the hose 54, the cleaning liquid inside the airbag 53 can only flow into the hose 54 and cannot flow in the opposite direction. Similarly, through the one-way valve between the cleaning liquid storage tank and the airbag 53, the cleaning liquid inside the cleaning liquid storage tank can only enter the airbag 53 through the one-way valve and cannot flow in the opposite direction.

[0047] In summary, the specific implementation process of this embodiment is as follows:

[0048] First, the output end of the hydraulic cylinder 21 pushes the L-shaped seat 23 to the right, causing the L-shaped seat 23 to slide to the right along the surface of the guide rail 22, preparing for the chamfering operation. When the center of the round seat 24 is at the same position as the axis of the workpiece to be processed, the operation of the hydraulic cylinder 21 is stopped.

[0049] Then, if Figure 4 , the electric telescopic rod 29 on the right side is stimulated. When the output end of the electric telescopic rod 29 on the right side moves to the left, it contacts the right end of the second protrusion 27. The output end of the electric telescopic rod 29 will continue to move to the left, and then push the second protrusion 27 to move to the left along the horizontal groove 1 241. Then the output end of the electric telescopic rod 29 moves to the right, and the electric telescopic rod 29 stops operating.

[0050] While the protrusion 27 moves to the left along the inner surface of the horizontal groove 1 241, the hydraulic cylinder 25 and the chamfering machine 2 282 are stimulated. At this time, the output end of the hydraulic cylinder 25 pushes the protrusion 1 26 upward, and the protrusion 1 26 moves upward along the inner surface of the vertical groove 242, and cooperates with the protrusion 2 27 to move to the left along the inner surface of the horizontal groove 1 241, so that the rotating rod 28 drives the chamfering machine 2 282 to rotate counterclockwise; and because the protrusion 2 27 is not at the center of gravity of the rotating rod 28, and the protrusion 2 27 is closer to the protrusion 1 26, the rotating rod 28 runs in an elliptical trajectory during the rotation process, and the inner surface of the beveled section of the workpiece is chamfered.

[0051] When the output end of the second hydraulic cylinder 25 pushes the first protrusion 26 upward and passes through the center of the round seat 24 and continues to move upward, the rotating rod 28 is driven by the first protrusion 26, and the end connected to the first protrusion 26 continues to move upward. Then the rotating rod 28 is driven to continue to rotate counterclockwise, and the second protrusion 27 is driven to slide to the right along the inner surface of the horizontal groove 1 241. At this time, the second chamfering machine 282 is driven by the rotating rod 28 to rotate to the lower left of the round seat 24, and the second chamfering machine 282 continues to chamfer the inner surface of the workpiece;

[0052] When the chamfering machine 282 is driven by the rotating rod 28 to rotate under the round seat 24, the protrusion 27 is located at the center of the round seat 24. Then the electric telescopic rod 29 on the left is triggered, and the output end of the electric telescopic rod 29 on the left moves to the right. After the output end of the electric telescopic rod 29 contacts the left end of the protrusion 27, the output end of the electric telescopic rod 29 on the left continues to push the protrusion 27 to the right, so that the protrusion 27 continues to slide to the right along the inner surface of the transverse groove 1 241. At this time, the protrusion 1 26 is driven by the output end of the hydraulic cylinder 25 to slide downward along the inner surface of the transverse groove 1 241, thereby realizing that the rotating rod 28 drives the chamfering machine 282 to continue to rotate counterclockwise, so that the chamfering machine 282 moves in an elliptical trajectory, and at the same time chamfers the inner surface of the beveled surface of the workpiece.

[0053] After the chamfering machine 282 moves in an elliptical circle and completes chamfering the inner surface of the workpiece, the operation of the chamfering machine 282 is stopped, and then the chamfering machine 1 281 is activated and the above operation is repeated to chamfer the outer surface of the beveled surface of the workpiece using the chamfering machine 1 281.

[0054] After the chamfering of the beveled surface of the workpiece is completed, the output end of the hydraulic cylinder 1 21 pulls the L-shaped seat 23 to the left, so that the chamfering machine 1 281 and the chamfering machine 2 282 and other structures are away from the workpiece to be processed without affecting subsequent processing operations.

[0055] Further, such as Figure 5 When the output end of the hydraulic cylinder 21 pushes the L-shaped seat 23 to the right to prepare for chamfering the bevel surface of the workpiece, the output end of the hydraulic cylinder 21 will drive the sliding roller 211 to move in the same direction. During the movement of the sliding roller 211 to the right, it cooperates with the limiting groove 621 to drive the L-shaped rod 62 to rotate clockwise around the axis of the rotating roller 2 61. Then, during the rotation process, the L-shaped rod 62 drives the sliding roller 66 and the L-shaped plate 64 and other structures to move backward to the rear side of the outer surface of the workpiece.

[0056] like Figure 7 When the second roller 61 is driven by the L-shaped rod 62 to rotate clockwise, the second roller 61 will drive the rotating plate 51 to rotate in the same direction. During the rotation of the rotating plate 51, the airbag 53 is continuously squeezed by the cooperation with the fixed plate 52, so that the cleaning liquid inside the airbag 53 enters the wiping cloth 68 through the one-way valve and the hose 54. Then, when the rotating plate 51 continues to squeeze the airbag 53, the cleaning liquid is continuously squeezed and penetrates into the wiping cloth 68.

[0057] Then, after the chamfering is completed, the L-shaped seat 23 is driven to move to the left by the output end of the hydraulic cylinder 1 21. The output end of the hydraulic cylinder 1 21 drives the sliding roller 1 211 to move to the left at the same time. During the movement of the sliding roller 1 211 to the left, the L-shaped rod 62 is driven to rotate counterclockwise around the axis of the rotating roller 2 61 by cooperating with the limiting groove 1 621. During the counterclockwise rotation of the L-shaped rod 62, the limiting groove 2 622 and the inner surface of the limiting groove 3 63 cooperate with each other. During the counterclockwise rotation of the L-shaped rod 62, the sliding roller 66 is driven to move forward along the inner surface of the limiting groove 3 63.

[0058] Further, such as Figure 8 As the sliding roller 66 moves forward, it drives the L-shaped plate 64, the sliding roller three 651, the arc plate 67 and the wiping cloth 68 to move in the same direction. At this time, the auxiliary component 4 cooperates to drive the workpiece to be processed to rotate continuously at high speed. As the wiping cloth 68 moves, the cleaning liquid is evenly applied to the outer surface of the workpiece to be processed until the sliding roller 66 moves forward to the front side wall of the inner surface of the limiting groove three 63. At this time, the wiping cloth 68 cleans the outer surface of the workpiece, and the L-shaped seat 23 moves to the left away from the workpiece.

[0059] Likewise, when the second roller 61 rotates counterclockwise, it drives the rotating plate 51 to rotate in the same direction, thereby stretching the airbag 53 and allowing the cleaning liquid in the cleaning liquid storage tank to enter the interior of the airbag 53 through the one-way valve.

[0060] In another embodiment of the present invention, Figure 9 The auxiliary component 4 includes a guide rail 2 45 fixedly mounted on the upper end of the operating table 1, and a bending rod 44 is slidably mounted on the outer surface of the guide rail 2 45. A T-shaped plate 41 is fixedly mounted on the left side of the upper end of the bending rod 44, and a motor 42 is fixedly mounted on the upper end of the horizontal part of the T-shaped plate 41. The output end of the motor 42 is fixedly connected to a fixed structure 43 for internally supporting and fixing the polishing workpiece. The front side of the right end of the bending rod 44 is fixedly connected to a limiting plate 2 46. A straight groove 2 461 and an oblique groove 2 462 are opened on the upper end of the limiting plate 46, and the straight groove 2 461 and the oblique groove 2 462 are connected.

[0061] The above-mentioned fixing structure 43 is a mature technology in the existing technology, and it only needs to meet the conditions of tightening and fixing the inside of the workpiece during the grinding and chamfering process to ensure that the position of the workpiece to be processed is not offset and the internal force is uniformly applied.

[0062] In another embodiment of the present invention, Figure 10 and Figure 11The grinding assembly 3 includes a hydraulic cylinder three 31 and a limit plate 1 33 fixedly mounted on the upper end of the operating table 1. The upper end of the limit plate 1 33 is provided with an inclined groove 1 331 and a straight groove 1 332, and the inclined groove 1 331 and the straight groove 1 332 are communicated with each other. The inner surface of the inclined groove 1 331 is slidably connected to a round roller 323, and the upper end of the round roller 323 is fixedly connected to a push block 32. The rear end of the push block 32 is provided with a transverse groove 2 322 whose inner surface is slidably connected to the output end of the hydraulic cylinder three 31. The transverse groove 2 322 is used to cooperate with the inclined groove 1 331 to adjust the position of the push block 32. The right end of the push block 32 is fixedly connected to a sliding roller 2 321, and the sliding roller 2 321 is used to cooperate with the straight groove 2 461 and the inclined groove 2 462 to adjust the position of the grinding workpiece. The upper end of the push block 32 is rotatably connected to a rotating roller 1 35. The outer surface of the rotating roller 1 35 is fixedly connected to a gear 351, and the upper end of the rotating roller 1 35 is fixedly connected to the grinding structure 34.

[0063] It should be noted that the above-mentioned grinding structure 34 is a mature technology in the prior art, and the outer surface of the workpiece is ground by the operating block of the grinding structure 34 .

[0064] The grinding assembly 3 further includes a rack 36 fixedly mounted on the upper end of the operating table 1 . The rack 36 cooperates with the gear 351 to adjust the grinding angle of the grinding structure 34 .

[0065] During the specific implementation of this embodiment: after the wiping cloth 68 evenly applies the cleaning liquid to the surface of the workpiece to be processed and the cleaning liquid dries, the hydraulic cylinder 31 is activated, so that the output end of the hydraulic cylinder 31 cooperates with the second transverse groove 322 to push the push block 32 forward. During the forward movement of the push block 32, the round roller 323 moves forward along the inner surface of the inclined groove 1 331, so that the push block 32, the rotating roller 1 35, and the grinding structure 34 move forward and approach the outer surface of the workpiece to be processed to the left. At the same time, the output end of the hydraulic cylinder 31 moves rightward along the inner surface of the second transverse groove 322.

[0066] like Figure 12 When the output end of the hydraulic cylinder three 31 pushes the push block 32, the round roller 323, the rotating roller 1 35 and the grinding structure 34 to move forward to the connection between the inclined groove 1 331 and the straight groove 1 332, the outer surface of the output end of the hydraulic cylinder three 31 is in close contact with the right side wall of the inner surface of the horizontal groove 2 322, and the grinding surface of the grinding structure 34 is in close contact with the outer surface of the workpiece, and the sliding roller 2 321 and the inner surface of the straight groove 2 461 are in the same vertical plane.

[0067] Furthermore, the grinding structure 34 and the motor 42 are excited, and then the output end of the motor 42 cooperates with the fixed structure 43 to drive the workpiece to rotate continuously, and at the same time the grinding structure 34 also rotates continuously, and the workpiece and the grinding belt of the grinding structure 34 rotate in opposite directions;

[0068] When the sanding belt of the grinding structure 34 runs in coordination with the rotation of the workpiece itself, the surface of the workpiece is ground. At the same time, the output end of the hydraulic cylinder three 31 continues to push the push block 32 forward, so that the round roller 323 continues to move forward along the inner surface of the straight groove one 332. During the forward movement of the round roller 323, the rotating roller one 35 and the grinding structure 34 are driven to move in the same direction, thereby achieving uniform grinding of the outer surface of the workpiece during the operation of the grinding structure 34. At this time, the sliding roller two 321 enters the inner surface of the straight groove two 461, and the sliding roller two 321 is driven to move forward along the inner surface of the straight groove two 461 during the movement of the push block 32. At this time, the positions of the limit plate two 46, the bending rod 44, the T-shaped plate 41 and the workpiece remain unchanged.

[0069] Similarly, when the push block 32 drives the grinding structure 34 to move forward through the roller 1 35 to grind the outer surface of the workpiece, after the push block 32 moves forward until the front end of the push block 32 contacts the rear end of the paddle 652, the push block 32 continues to drive the roller 1 35 and the grinding structure 34 to move forward. At this time, the push block 32 will push the paddle 652 to move forward, and then in the process of the paddle 652 moving forward, the fixed block 65 and the sliding roller 3 651 as well as the curved plate 67 and the wiping cloth 68 are driven to move forward at the same time. When the sliding roller 3 651 and the fixed block 65 are pushed forward, the sliding roller 3 651 slides forward along the inner surface of the slide groove 641. At this time, the sliding roller 66 and the L-shaped plate 64 are stationary. At the same time, after the wiping cloth 68 is pushed forward to separate from the outer surface of the workpiece, the cleaning liquid on the outer surface of the workpiece will dry before the grinding structure 34 grinds it, thereby achieving that during the process of the grinding structure 34 grinding the workpiece, the wiping cloth 68 and the like will not affect the treatment of the outer surface of the workpiece.

[0070] Further, such as Figure 13 When the push block 32 and the sliding roller 321 move forward to the connection between the straight groove 461 and the inclined groove 462, the grinding structure 34 has just completed the grinding of the entire outer surface of the workpiece, and the sliding roller 321 is located at the connection between the straight groove 461 and the inclined groove 462.

[0071] Next, the motor 42 and the grinding structure 34 are stopped, and the output end of the hydraulic cylinder 31 continues to push forward. At this time, the right side of the rack 36 is engaged with the outer surface of the gear 351. When the push block 32 drives the roller 1 35, the gear 351 and the grinding structure 34 to continue to move forward along the straight groove 1 332, the gear 351 drives the roller 1 35 and the grinding structure 34 to rotate counterclockwise. After the gear 351 continues to move forward and disengages from the rack 36, the sanding surface of the grinding structure 34 is parallel to the bevel surface of the workpiece to be processed.

[0072] Similarly, if Figure 14When the gear 351 cooperates with the rack 36 to adjust the angle of the grinding structure 34, the second sliding roller 321 is driven to move forward along the inner surface of the second inclined groove 462. Through cooperation with the second inclined groove 462, during the forward movement of the second sliding roller 321, the second limiting plate 46, the bending rod 44, and the T-shaped plate 41 are simultaneously moved to the right. During the rightward movement of the T-shaped plate 41, the motor 42, the fixed structure 43, and the workpiece are simultaneously driven to move to the right.

[0073] Then, after the angle adjustment of the grinding structure 34 is completed, the workpiece is driven to move rightward until the beveled surface of the workpiece is in close contact with the grinding structure 34 .

[0074] Next, the grinding structure 34 and the motor 42 are stimulated, and at the same time, the hydraulic cylinder 31 continues to push the push block 32 forward. In the process of the push block 32 driving the round roller 323 to move forward along the inner surface of the straight groove 332, the rotating roller 35 and the grinding structure 34 continue to move forward slowly. At the same time, the sliding roller 321 slides along the inner surface of the inclined groove 462, thereby driving the limit plate 2 46 and the bending rod 44 as well as the T-shaped plate 41 and the workpiece to move to the right, thereby achieving uniform grinding of the bevel surface of the workpiece.

[0075] After the grinding structure 34 finishes grinding the beveled surface of the workpiece, the push block 32 pushes the dial plate 652 so that the sliding roller 3 651 is located on the front side wall of the inner surface of the sliding groove 641 , and the sliding roller 2 321 is located on the front side wall of the inner surface of the inclined groove 2 462 .

[0076] After the grinding is completed, the inner support lock of the workpiece by the fixed structure 43 is released, and the chamfered and ground workpiece is removed. Then, the push block 32 is pulled backward through the output end of the hydraulic cylinder 31. As the push block 32 drives the round roller 323 to move backward along the inner surface of the straight groove 1 332, the sliding roller 2 321 cooperates with the inner surface of the inclined groove 2 462 to drive the bending rod 44, the T-shaped plate 41, and the motor 42 to reset.

[0077] Similarly, the front end of the push block 32 no longer squeezes the push plate 652. At this time, the stretched springs 642 pull the fixed block 65 and the sliding roller three 651 backward, so that the sliding roller three 651 drives the arc plate 67 and the wiping cloth 68 to move backward along the inner surface of the spring 642, so that the wiping cloth 68 is again in close contact with the front side of the outer surface of the next workpiece to be processed.

[0078] During the chamfering and grinding process, the protective cover 11 is used to prevent dust and other pollutants from affecting the operating environment. It should be noted that the specific installation method, circuit connection method, and control method of the motor 42, hydraulic cylinder 1 21, hydraulic cylinder 25, and hydraulic cylinder 3 31 used in the present invention are all conventional designs and will not be elaborated in detail in this invention.
