The transmission gear is used to sleeved on the bar. The plurality of grinding heads and the plurality of transmission members are all arranged at intervals along the circumferential direction of the transmission gear. The number of grinding heads is the same as that of the transmission members, and one grinding head is connected to one transmission member. Adjacent two transmission members are connected by a connecting rod. All transmission members are meshed with the transmission gear. The driving member is connected to one transmission member.

Baffles are fixedly connected to the ends of the two support rods far away from the clamping cylinder, and the baffles abut against the fixing blocks on the two limiting rods.

[0012] Preferably, a method for using a grinding and polishing device for bars includes the following steps:

[0013] S1: When the driving motor drives the driving rod to rotate, the driving rod rotates and drives the first bevel gear to rotate. The first bevel gear rotates and drives the second bevel gear to rotate. The second bevel gear drives the rotating rod to rotate. The rotating rod rotates and drives the two eccentric turntables to rotate. The rotation of the eccentric turntable drives the two swing frames to move with the rotating rod as the center. The other ends of the two swing frames drive the moving frame to deflect back and forth on the processing table. When the moving frame deflects, the two clamping frames arranged on the moving frame drive the moving chuck to reciprocate on the driving rod. Since the propulsion device contacts the clamping groove on the moving chuck, the propulsion device can be driven to reciprocate when the moving chuck reciprocates. The reciprocating movement of the propulsion device can feed the passed rods in the direction of the polishing device at equal intervals.

[0014] S2: When the rod passes through the clamping opening and the two placement openings on the clamping frame, the mobile chuck moves back and forth on the driving rod, and when the clamping groove on the mobile chuck makes the sliding frame move toward the direction of the polishing device through the clamping ball, the sliding frame moves toward the direction of the polishing device, and under the restriction of the pressure spring between the clamping frame and the accommodating cavity, the sliding frame and the clamping frame will be relatively displaced, and a number of clamping balls on the inclined surface of the clamping frame will contact the conical surface on the accommodating cavity. At this time, driven by the conical surface, a number of clamping balls will be squeezed toward the outer wall of the rod in the clamping frame. At this time, a number of clamping balls on the clamping frame will clamp the outer wall of the rod, and then when the sliding frame moves toward the direction of the polishing device, it can drive the clamped rod to move toward the direction of the polishing device, and when the mobile chuck drives the sliding frame to move in the direction away from the polishing device, the pressure springs arranged between the clamping frame and the sliding frame have the same acting force, so that the clamping balls on the clamping frame are in contact with the annular surface in the accommodating cavity, so that the clamping balls are not in abutment with the outer wall of the rod;

[0015] S3: When the sliding frame moves toward the direction of the carrying box, after the outer wall of the sliding frame contacts the end face of the cartridge, the sliding frame will squeeze the cartridge, so that the cartridge moves in the carrying plate through the two support rods. At this time, the two hinged frames arranged on the outer wall of the cartridge will squeeze the friction connecting plates slidably arranged in the card slots, and the two friction connecting plates will move toward the inner wall of the rotating outer cylinder. At this time, the friction connecting plates abut against the inner wall of the rotating outer cylinder. Since the rotation of the driving rod can drive the driving gear to rotate at this time, the driving gear meshes with the annular gear on the rotating outer cylinder to drive the rotating outer cylinder to rotate. When the friction connecting plates abut against the rotating outer cylinder, they will drive the carrying plate to rotate synchronously, and the resistance protrusions arranged in the cartridge will abut against the carrying plate at this time, and the resistance protrusions move toward the outer wall of the rod in the cartridge to clamp the rod. Then, when the carrying plate rotates to drive the cartridge to rotate, the cartridge will cause the rod to rotate through the resistance protrusions, and the rod rotates and contacts with the polishing device, thereby realizing the polishing operation of the rod.

[0016] S4: When the sliding frame squeezes the chuck to move it toward the direction of the supporting disk, the two support rods on the chuck will drive the baffle to move, and the baffle squeezes the fixed blocks on the two limit rods, and the limit rods will move on the fixed disk. At this time, the movement of the limit rod drives the two limit wheels to contact the inclined groove on the adjusting sleeve, so that the inclined groove can drive the adjusting sleeve to rotate, and the rotation of the adjusting sleeve will drive the limit groove to deflect the set limit block. Since the limit frame is hinged on the fixed disk, the limit block will drive the limit frame to move toward the direction of the circular mouth, and the grinding knife on the limit frame will contact the outer wall of the rod at the circular mouth. At this time, the interference protrusion on the chuck is in a state of clamping the rod, and the rod is rotating, so that the outer wall of the rod can contact the grinding knife.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, when the movable chuck moves back and forth, it can drive the propulsion device to move back and forth. The reciprocating movement of the propulsion device can feed the passed rods toward the polishing device at equal intervals, so that when the polishing device polishes the rods, it can effectively polish the polishing area of the rods comprehensively.

[0019] In the present invention, when the sliding frame moves toward the direction of the polishing device, it can drive the clamped rod to move toward the direction of the polishing device, and when the movable chuck drives the sliding frame to move in the direction away from the polishing device, at this time, the forces of the pressure springs arranged between the clamping frame and the sliding frame are the same, so that the clamping ball on the clamping frame contacts the annular surface in the accommodating cavity, so that the clamping ball and the outer wall of the rod are not in abutment state, and then the sliding frame can intermittently drive the rod in the clamping frame to move back and forth intermittently when moving back and forth, so that the polishing device can intermittently polish the rod, so that the polishing part of the rod briefly stays under the polishing device, so that the polishing device improves the polishing efficiency of the rod.

[0020] In the present invention, when the carrier plate rotates and drives the chuck to rotate, the chuck will cause the rod to rotate through the abutment protrusion, and the rod rotates and contacts with the polishing device, thereby realizing the polishing operation of the rod. When the sliding frame moves toward the direction of the polishing device, the sliding frame gradually moves away from the chuck, the abutment protrusion on the chuck separates from the rod, and the friction connecting plate no longer contacts the inner wall of the rotating outer cylinder, so that the rod can be fed toward the polishing device. Through this arrangement, after the rod is intermittently fed during the processing process, the rod can be rotated to cooperate with the polishing device to realize intermittent polishing of the rod.

[0021] In the present invention, the limit block drives the limit frame to move toward the circular mouth, and the grinding knife on the limit frame will contact the outer wall of the rod at the circular mouth. At this time, the interference protrusion on the chuck is in a state of clamping the rod, and the rod is rotating, so that the outer wall of the rod can contact the grinding knife. Before the rod is polished with the polishing device, it first contacts the grinding knife, and the small protrusions on the outer wall of the rod can be ground. After the preliminary processing of the rod, the subsequent polishing device will perform precision processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a grinding and polishing device for bars, including a processing table 1, a slideway 11 is opened on the processing table 1, a propelling device 3 for moving the bar is arranged in the slideway 11, a driving device 2 is also rotatably arranged on the processing table 1, the driving device 2 is in transmission cooperation with the propelling device 3, a carrying box 12 is fixedly arranged on the top of the processing table 1, a rotary clamping device 4 is rotatably arranged in the carrying box 12, the rotary clamping device 4 is in transmission cooperation with the driving device 2, and the rotary clamping device 4 is in contact cooperation with the propelling device 3, a grinding device 5 is also arranged in the carrying box 12, placing openings 13 are opened on the carrying box 12 and the processing table 1, and the two placing openings 13 are on the same axis, and a polishing device 14 is arranged above the placing opening 13 on the processing table 1 on the top of the processing table 1.

[0036] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown in the figure, the driving device 2 includes a driving motor 21 fixedly connected to the outer wall of the processing table 1. The main shaft of the driving motor 21 is drivingly connected to a driving rod 22. The driving rod 22 is rotationally engaged with the processing table 1. A first bevel gear 23 is fixedly connected to the driving rod 22. A rotating rod 24 is also rotatably arranged on the processing table 1. A second bevel gear 25 is fixedly connected to the rotating rod 24. The first bevel gear 23 meshes with the second bevel gear 25;

[0037] Both ends of the rotating rod 24 are eccentrically connected with eccentric turntables 26. Swing frames 27 are fixedly sleeved on both eccentric turntables 26. A moving frame 28 is hingedly arranged on the processing table 1. One end of the swing frame 27 away from the eccentric turntable 26 is hingedly engaged with the moving frame 28. A moving chuck 29 is clamped on the driving rod 22. A clamping groove 210 is formed on the moving chuck 29. Two clamping frames 211 are hingedly arranged on the moving frame 28. The two clamping frames 211 are rotationally engaged with the clamping groove 210 on the moving chuck 29. The propulsion device 3 contacts the clamping groove 210 on the moving chuck 29;

[0038] Insert the bar into the placement openings 13 on the bearing box 12 and the processing table 1. The bar passes through the propulsion device 3. When the driving rod 22 rotates driven by the driving motor 21, the rotation of the driving rod 22 drives the first bevel gear 23 to rotate. The rotation of the first bevel gear 23 drives the second bevel gear 25 to rotate. The second bevel gear 25 will drive the rotating rod 24 to rotate. The rotation of the rotating rod 24 will cause the two eccentric turntables 26 to rotate. The rotation of the eccentric turntables 26 drives the two swing frames 27 to move around the rotating rod 24. The other ends of the two swing frames 27 will drive the moving frame 28 to reciprocally deflect on the processing table 1. When the moving frame 28 deflects, the two clamping frames 211 arranged on the moving frame 28 will drive the moving chuck 29 to reciprocally move on the driving rod 22. Since the propulsion device 3 contacts the clamping groove 210 on the moving chuck 29, when the moving chuck 29 reciprocally moves, it can drive the propulsion device 3 to reciprocally move. By the reciprocal movement of the propulsion device 3, the bar passing through can be fed at equal intervals in the direction of the polishing device 14, enabling the polishing device 14 to effectively polish the entire polishing area of the bar during polishing.

[0039] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the propulsion device 3 includes a sliding frame 31 slidably disposed in the slideway 11. A fixing rod 34 is fixedly provided at the bottom of the sliding frame 31. A clamping ball 35 is disposed in the clamping groove 210 on the moving chuck 29 towards the fixing rod 34. An accommodating cavity 32 is formed in the sliding frame 31. A conical surface 33 is provided on the inner wall of the accommodating cavity 32. A clamping frame 36 is slidably disposed in the accommodating cavity 32. A pressure spring 37 is disposed between the clamping frame 36 and the accommodating cavity 32. An inclined surface 38 is formed on the clamping frame 36. A plurality of clamping balls 39 are embedded around the inclined surface 38, and the plurality of clamping balls 39 are in contact with the conical surface 33 in the accommodating cavity 32. A clamping opening 310 coaxial with the placing opening 13 is formed at the axis of the sliding frame 31 and the clamping frame 36;

[0040] When the bar passes through the clamping opening 310 on the clamping frame 36 and the two placing openings 13, the moving chuck 29 reciprocates on the driving rod 22. When the clamping groove 210 on the moving chuck 29 moves the sliding frame 31 towards the polishing device 14 through the clamping ball 35, the sliding frame 31 moves towards the polishing device 14. Under the restriction of the pressure spring 37 between the clamping frame 36 and the accommodating cavity 32, a relative displacement occurs between the sliding frame 31 and the clamping frame 36. A plurality of clamping balls 39 on the inclined surface 38 of the clamping frame 36 will contact the conical surface 33 on the accommodating cavity 32. At this time, driven by the conical surface 33, the plurality of clamping balls 39 will be pressed against the outer wall of the bar in the clamping frame 36. At this time, the plurality of clamping balls 39 on the clamping frame 36 clamp the outer wall of the bar. Then, when the sliding frame 31 moves towards the polishing device 14, it can drive the clamped bar to move towards the polishing device 14. When the moving chuck 29 drives the sliding frame 31 to move away from the polishing device 14, at this time, the acting force of the pressure spring 37 disposed between the clamping frame 36 and the sliding frame 31 is the same. Then, the clamping balls 39 on the clamping frame 36 contact the toroidal surface in the accommodating cavity 32, so that the clamping balls 39 are not in contact with the outer wall of the bar. Then, when the sliding frame 31 reciprocates, it can intermittently drive the bar in the clamping frame 36 to reciprocate intermittently, so that the polishing device 14 can polish the bar intermittently, making the polished part of the bar stay briefly below the polishing device 14, and improving the polishing efficiency of the polishing device 14 for the bar.

[0041] In this embodiment, as Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, the rotary clamping device 4 includes a rotary outer cylinder 41 rotatably arranged on the outer wall of the bearing box 12. An annular gear 42 is fixedly arranged on the outer wall of the rotary outer cylinder 41. A driving gear 43 is fixedly connected to the driving rod 22. The driving gear 43 meshes with the annular gear 42. A bearing plate 44 is rotatably arranged on the inner wall of the rotary outer cylinder 41. Support rods 45 are slidably arranged correspondingly on the bearing plate 44. A clamping cylinder 46 is fixedly connected to the two support rods 45. Connecting springs 47 are sleeved on the two support rods 45. Two ends of each connecting spring 47 are respectively connected to the bearing plate 44 and the clamping cylinder 46. The outer wall of the clamping cylinder 46 abuts against the outer wall of the sliding frame 31;

[0042] Hinged frames 48 are hinged at both ends of the clamping cylinder 46. Corresponding card slots 49 are formed in the bearing plate 44. Friction connecting plates 410 are slidably arranged in the two card slots 49. The two friction connecting plates 410 are arranged corresponding to the hinged frames 48 at both ends of the clamping cylinder 46. The friction connecting plates 410 are hinged and matched with the other ends of the hinged frames 48 away from the clamping cylinder 46. The friction connecting plates 410 are in frictional contact with the inner wall of the rotary outer cylinder 41. Elastic abutting protrusions 411 are further arranged on the outer wall of the clamping cylinder 46. The abutting protrusions 411 are in abutting cooperation with the bearing plate 44;

[0043] When the sliding carriage 31 moves towards the direction of the bearing box 12, after the outer wall of the sliding carriage 31 contacts the end face of the cartridge 46, the sliding carriage 31 will squeeze the cartridge 46, causing the cartridge 46 to move within the bearing plate 44 through the two support rods 45. At this time, the two hinge brackets 48 provided on the outer wall of the cartridge 46 will squeeze the friction connection plates 410 slidably arranged in the card slots 49, and the two friction connection plates 410 will move towards the inner wall of the rotating outer cylinder 41. At this time, the friction connection plates 410 are in contact with the inner wall of the rotating outer cylinder 41. Since the driving rod 22 can drive the driving gear 43 to rotate at this time, and the driving gear 43 meshes with the annular gear 42 on the rotating outer cylinder 41 to drive the rotating outer cylinder 41 to rotate. After the friction connection plates 410 are in contact with the rotating outer cylinder 41, they will drive the bearing plate 44 to rotate synchronously. At this time, the abutting protrusions 411 arranged in the cartridge 46 are in contact with the bearing plate 44, and the abutting protrusions 411 move towards the outer wall of the bar material located in the cartridge 46 to clamp the bar material. Then, when the bearing plate 44 rotates to drive the cartridge 46 to rotate, the cartridge 46 will cause the bar material to rotate through the abutting protrusions 411. The rotating bar material contacts the polishing device 14, thereby realizing the polishing operation of the bar material. When the sliding carriage 31 moves towards the direction of the polishing device 14, the sliding carriage 31 gradually moves away from the cartridge 46, the abutting protrusions 411 on the cartridge 46 are separated from the bar material, and the friction connection plates 410 are no longer in contact with the inner wall of the rotating outer cylinder 41. Thus, the bar material can be fed towards the direction of the polishing device 14. Through this setting, after the bar material is intermittently fed during the processing process, the bar material can rotate and cooperate with the polishing device 14 to realize intermittent polishing of the bar material.

[0044] In this embodiment, as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, the grinding device 5 includes a fixed disk 51 fixedly connected to the inner wall of the bearing box 12. A circular opening 52 coaxial with the placement opening 13 is provided on the fixed disk 51. An adjusting sleeve disk 53 is rotatably arranged on the fixed disk 51. A limiting groove 54 is provided on the adjusting sleeve disk 53. Three limiting blocks 55 are hinged around the circumference of the adjusting sleeve disk 53 in the limiting groove 54. Limiting frames 56 corresponding to the three limiting blocks 55 are provided on the fixed disk 51. The limiting frames 56 are hinged and matched with the fixed disk 51. A through groove is provided on the limiting block 55. The limiting frame 56 passes through the through groove of the corresponding limiting block 55. The end of the limiting frame 56 is arranged towards the circular opening 52 to provide a grinding tool 57;

[0045] The adjusting sleeve plate 53 is provided with oppositely arranged inclined slots 58, and the fixed plate 51 is slidably provided with corresponding limiting rods 59. The two limiting rods 59 are arranged corresponding to the inclined slots 58 on the adjusting sleeve plate 53. Limiting wheels 510 are arranged on both of the two limiting rods 59, and the limiting wheels 510 are in contact with the correspondingly arranged inclined slots 58. Return springs 511 are sleeved on both of the two limiting rods 59. Fixed blocks are fixedly arranged at the ends of the two limiting rods 59 far away from the fixed plate 51. The ends of the two support rods 45 far away from the cartridge 46 are fixedly connected with a baffle plate 512, and the baffle plate 512 abuts against the fixed blocks on the two limiting rods 59;

[0046] When the sliding frame 31 presses the cartridge 46 to move the cartridge 46 towards the bearing plate 44, the two support rods 45 on the cartridge 46 will drive the baffle plate 512 to move. The baffle plate 512 presses the fixed blocks on the two limiting rods 59, and the limiting rods 59 will move on the fixed plate 51. At this time, the movement of the limiting rods 59 drives the two limiting wheels 510 to contact the inclined slots 58 on the adjusting sleeve plate 53, so that the inclined slots 58 can drive the adjusting sleeve plate 53 to rotate. The rotation of the adjusting sleeve plate 53 will drive the limiting slot 54 to deflect the arranged limiting block 55. Since the limiting frame 56 is hinged to the fixed plate 51, at this time, the limiting block 55 will drive the limiting frame 56 to move towards the round opening 52. The grinding tool 57 on the limiting frame 56 will contact the outer wall of the bar at the round opening 52. At this time, the abutting convex block 411 on the cartridge 46 is in a state of clamping the bar, and the bar is rotating. Therefore, the outer wall of the bar can contact the grinding tool 57. Before the bar contacts the polishing device 14 for polishing, it first contacts the grinding tool 57, which can grind the fine protrusions on the outer wall of the bar. After the bar is preliminarily processed, it is precisely processed by the subsequent polishing device 14.

[0047] The usage method and advantages of the present invention: The usage method of the grinding and polishing device for bars is as follows: The working process is as follows:

[0048] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 shown:

[0049] S1: When the driving rod 22 rotates driven by the driving motor 21, the rotation of the driving rod 22 drives the first bevel gear 23 to rotate. The rotation of the first bevel gear 23 drives the second bevel gear 25 to rotate. The second bevel gear 25 then drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 causes the two eccentric turntables 26 to rotate. The rotation of the eccentric turntables 26 drives the two swing frames 27 to move around the rotating rod 24 as the center. The other ends of the two swing frames 27 drive the moving frame 28 to reciprocally deflect on the processing table 1. When the moving frame 28 deflects, the two clamping frames 211 provided on the moving frame 28 drive the moving chuck 29 to reciprocally move on the driving rod 22. Since the propulsion device 3 contacts the clamping groove 210 on the moving chuck 29, when the moving chuck 29 reciprocally moves, it can drive the propulsion device 3 to reciprocally move. Through the reciprocal movement of the propulsion device 3, the rod passing through can be fed at equal intervals in the direction towards the polishing device 14;

[0050] S2: When the rod passes through the clamping opening 310 on the clamping frame 36 and the two placing openings 13, the moving chuck 29 reciprocally moves on the driving rod 22. When the clamping groove 210 on the moving chuck 29 drives the sliding frame 31 to move in the direction towards the polishing device 14 through the clamping ball 35, as the sliding frame 31 moves in the direction towards the polishing device 14, under the restriction of the pressure spring 37 between the clamping frame 36 and the receiving cavity 32, a relative displacement occurs between the sliding frame 31 and the clamping frame 36. Several clamping balls 39 on the inclined surface 38 of the clamping frame 36 contact the conical surface 33 on the receiving cavity 32. At this time, driven by the conical surface 33, several clamping balls 39 will squeeze towards the outer wall of the rod within the clamping frame 36. At this time, several clamping balls 39 on the clamping frame 36 clamp the outer wall of the rod. Therefore, when the sliding frame 31 moves in the direction towards the polishing device 14, it can drive the clamped rod to move in the direction towards the polishing device 14. When the moving chuck 29 drives the sliding frame 31 to move in the direction away from the polishing device 14, at this time, the acting force of the pressure spring 37 provided between the clamping frame 36 and the sliding frame 31 is the same. As a result, the clamping balls 39 on the clamping frame 36 contact the annular surface within the receiving cavity 32, and the clamping balls 39 are not in contact with the outer wall of the rod;

[0051] S3: When the sliding frame 31 moves towards the direction of the bearing box 12, after the outer wall of the sliding frame 31 contacts the end face of the cartridge 46, the sliding frame 31 will squeeze the cartridge 46, causing the cartridge 46 to move within the bearing plate 44 through the two support rods 45. At this time, the two hinge frames 48 provided on the outer wall of the cartridge 46 will squeeze the friction connecting plates 410 slidably arranged in the card slots 49, and the two friction connecting plates 410 will move towards the inner wall of the rotating outer cylinder 41. At this time, the friction connecting plates 410 are in contact with the inner wall of the rotating outer cylinder 41. Since the driving rod 22 can drive the driving gear 43 to rotate at this time, and the driving gear 43 meshes with the annular gear 42 on the rotating outer cylinder 41 to drive the rotating outer cylinder 41 to rotate. After the friction connecting plates 410 are in contact with the rotating outer cylinder 41, they will drive the bearing plate 44 to rotate synchronously. At this time, the abutting protrusion 411 arranged in the cartridge 46 abuts against the bearing plate 44, and the abutting protrusion 411 moves towards the outer wall of the bar material in the cartridge 46 to clamp the bar material. Then, when the bearing plate 44 rotates to drive the cartridge 46 to rotate, the cartridge 46 will cause the bar material to rotate through the abutting protrusion 411. The rotating bar material contacts the polishing device 14, thereby realizing the polishing operation of the bar material;

[0052] S4: When the sliding frame 31 squeezes the cartridge 46 to make the cartridge 46 move towards the bearing plate 44, the two support rods 45 on the cartridge 46 will drive the baffle 512 to move. The baffle 512 squeezes the fixed blocks on the two limit rods 59, and the limit rods 59 will move on the fixed plate 51. At this time, the movement of the limit rods 59 drives the two limit wheels 510 to contact the inclined slots 58 on the adjusting sleeve plate 53, so that the inclined slots 58 can drive the adjusting sleeve plate 53 to rotate. The rotation of the adjusting sleeve plate 53 will drive the limit slot 54 to deflect the arranged limit block 55. Since the limit frame 56 is hinged on the fixed plate 51, at this time, the limit block 55 will drive the limit frame 56 to move towards the round opening 52. The grinding knife 57 on the limit frame 56 will contact the outer wall of the bar material at the round opening 52. At this time, the abutting protrusion 411 on the cartridge 46 is in a state of clamping the bar material, and the bar material is rotating, so that the outer wall of the bar material can contact the grinding knife 57.

9. A method for using a grinding and polishing device for bars, which uses a grinding and polishing device for bars as described in any one of claims 1-8, characterized in that, It includes the following steps: S1: When the driving rod (22) rotates driven by the driving motor (21), the driving rod (22) rotates to drive the first bevel gear (23) to rotate. The first bevel gear (23) rotates to drive the second bevel gear (25) to rotate. The second bevel gear (25) will drive the rotating rod (24) to rotate. When the rotating rod (24) rotates, the two eccentric turntables (26) will rotate. The eccentric turntables (26) rotate to drive the two swing frames (27) to move around the rotating rod (24) as the center. The other ends of the two swing frames (27) will drive the moving frame (28) to reciprocally deflect on the processing table (1). When the moving frame (28) deflects, the two clamping frames (211) arranged on the moving frame (28) will drive the moving chuck (29) to reciprocally move on the driving rod (22). Since the propulsion device (3) is in contact with the clamping groove (210) on the moving chuck (29), when the moving chuck (29) reciprocally moves, it can drive the propulsion device (3) to reciprocally move. By the reciprocal movement of the propulsion device (3), the passing bar can be fed at equal intervals towards the direction of the polishing device (14). S2: When the bar passes through the clamping opening (310) and the two placing openings (13) on the clamping frame (36), the moving chuck (29) reciprocates on the driving rod (22). When the clamping groove (210) on the moving chuck (29) causes the sliding frame (31) to move towards the polishing device (14) through the clamping balls (35), the sliding frame (31) moves towards the polishing device (14). Under the restriction of the pressure spring (37) between the clamping frame (36) and the accommodating cavity (32), relative displacement occurs between the sliding frame (31) and the clamping frame (36). Several clamping balls (39) on the inclined surface (38) of the clamping frame (36) will contact the conical surface (33) on the accommodating cavity (32). At this time, driven by the conical surface (33), several clamping balls (39) will squeeze towards the outer wall of the bar inside the clamping frame (36). At this time, several clamping balls (39) on the clamping frame (36) clamp the outer wall of the bar. Then, when the sliding frame (31) moves towards the polishing device (14), it can drive the clamped bar to move towards the polishing device (14). When the moving chuck (29) drives the sliding frame (31) to move away from the polishing device (14), the acting force of the pressure spring (37) arranged between the clamping frame (36) and the sliding frame (31) is the same at this time. Then, the clamping balls (39) on the clamping frame (36) contact the annular surface in the accommodating cavity (32), and the clamping balls (39) are not in contact with the outer wall of the bar; S3: When the sliding frame (31) moves towards the carrying box (12), after the outer wall of the sliding frame (31) contacts the end face of the cartridge (46), the sliding frame (31) will squeeze the cartridge (46), causing the cartridge (46) to move in the carrying disc (44) through the two support rods (45). At this time, the two articulated frames (48) arranged on the outer wall of the cartridge (46) will squeeze the friction connecting plates (410) slidably arranged in the card slots (49). The two friction connecting plates (410) will move towards the inner wall of the rotating outer cylinder (41). At this time, the friction connecting plates (410) are in contact with the inner wall of the rotating outer cylinder (41). Since the driving rod (22) rotates at this time and can drive the driving gear (43) to rotate, and the driving gear (43) meshes with the annular gear (42) on the rotating outer cylinder (41) to drive the rotating outer cylinder (41) to rotate. When the friction connecting plates (410) are in contact with the rotating outer cylinder (41), they will drive the carrying disc (44) to rotate synchronously. At this time, the abutting convex block (411) arranged in the cartridge (46) abuts against the carrying disc (44). The abutting convex block (411) moves towards the outer wall of the bar in the cartridge (46) to clamp the bar. Then, when the carrying disc (44) rotates to drive the cartridge (46) to rotate, the cartridge (46) will cause the bar to rotate through the abutting convex block (411). The bar rotates and contacts the polishing device (14), thus realizing the polishing operation of the bar; S4: When the sliding carriage (31) squeezes the cartridge (46) to move the cartridge (46) towards the bearing plate (44), the two support rods (45) on the cartridge (46) will drive the baffle plate (512) to move. The baffle plate (512) squeezes the fixed blocks on the two limit rods (59), and the limit rods (59) will move on the fixed plate (51). At this time, the movement of the limit rods (59) drives the two limit wheels (510) to contact the inclined slots (58) on the adjusting sleeve plate (53), so that the inclined slots (58) can drive the adjusting sleeve plate (53) to rotate. The rotation of the adjusting sleeve plate (53) will drive the limit slot (54) to deflect the provided limit block (55). Since the limit frame (56) is hinged on the fixed plate (51), at this time, the limit block (55) will drive the limit frame (56) to move towards the round opening (52). The grinding knife (57) on the limit frame (56) will contact the outer wall of the bar at the round opening (52). At this time, the abutting convex block (411) on the cartridge (46) is in a state of clamping the bar, and the bar is rotating, so that the outer wall of the bar can contact the grinding knife (57).
