[0058] First, loosen the screw block 63 and then pull the second enclosure plate 58 away from or closer to the first enclosure plate 57. Adjust the distance between the second enclosure plate 58 and the first enclosure plate 57 according to the connecting rod 74. After the adjustment is completed, tighten the screw block 63, and then place multiple connecting rods 74 in the first enclosure plate 57 and the second enclosure plate 58 for storage. At this time, the connecting rods 74 are located on the closed plate 69 and arranged from bottom to top, and the connecting rods 74 in contact with the closed plate 69 correspond to the first side groove 59.

[0059] The second step is to push the push plate 64 closer to the second side groove 66 by the sixth power source 68. At this time, the two push blocks 65 will move with the push plate 64. The two push blocks 65 can push the connecting rod 74, which is in contact with the closing plate 69, out of the first side groove 59. One side of the pushed connecting rod 74 contacts the two baffles 70.

[0060] Third, the first power source 16 drives one of the sprockets 12 to rotate. At this time, one of the sprockets 12 will drive the other sprocket 12 to rotate through the chain 13. The chain 13 will drive the slide 10 to slide on the track through the cooperation of the connecting column 15 and the push plate 14 until the slide 10 is moved to the position corresponding to the storage mechanism. At this time, the push plate 14 contacts one side of the first limit rod 17. Then, the second power source 27 drives the slide plate 26 to move vertically. At this time, the mounting plate 77, turntable 34, and rotating frame 35 will follow the slide plate 26 to move until the first pneumatic claw 29 on the mounting plate 77 corresponds to one of the rings 75 on the connecting rod 74. Then, the nut 48 is loosened to push the adjusting plate 44 to slide in the elongated groove 43, thereby adjusting the position of the second pneumatic claw 30 so that the second pneumatic claw 30 corresponds to the other ring 75 in the connecting rod 74.

[0061] Fourth, the third power source 28 drives the rotating frame 35 to move the mounting plate 77 horizontally away from the slide plate 26 until the contact block 31 contacts one side of the connecting rod 74. At this time, the gripping ends of the first air gripper 29 and the second air gripper 30 will be located in the upper middle of the two rings 75 in the connecting rod 74, respectively. Then, the gripping ends of the first air gripper 29 and the second air gripper 30 support the inner wall of the rings 75 from the top and bottom to complete the gripping of the connecting rod 74. The baffle 70 on the closed plate 69 will not affect the operation of the first air gripper 29 and the second air gripper 30.

[0062] Fifth, the second power source 27 drives the slide plate 26 to move vertically upward. At this time, the mounting plate 77, turntable 34, rotating frame 35, first air gripper 29, second air gripper 30, and the connecting rod 74 gripped by the first air gripper 29 and second air gripper 30 will move upward with the slide plate 26. When the first air gripper 29 and second air gripper 30 have both moved above the two baffles 70, the first power source 16 causes the slide block 10 to slide on the track towards the grinding device 3 until the connecting rod 74 is engaged. Move to the position corresponding to the grinding wheel 2. At this time, the movable plate 32 in the slide 10 is located between the fixed plate 72 and the side plate 71, and the rollers 73 on the fixed plate 72 and the side plate 71 are in contact with the movable plate 32. Then, the third power source 28 pushes the rotating frame 35 to move the mounting plate 77 away from the slide plate 26. At this time, the connecting rod 74 gripped by the first air gripper 29 and the second air gripper 30 will approach the grinding wheel 2 of the grinding device 3. At this time, the grinding wheel 2 of the grinding device 3 can grind one side of the connecting rod 74.

[0063] Step 6: After one side of the connecting rod 74 is polished, the third power source 28 pushes the rotating frame 35 to move the mounting plate 77 closer to the slide plate 26. Then, the first power source 16 causes the slide 10 to move along the track towards the transfer platform 52 until the slide 10 moves to the front of the transfer mechanism and the suspension plate 19 on the push plate 14 contacts the third limiting plate 23. At this time, the slide 10 corresponds to the transfer mechanism, and the connecting rod 74 gripped by the first pneumatic gripper 29 and the second pneumatic gripper 30 is located above and in front of the transfer platform 52. Then, the third power source 28 pushes... The rotating frame 35 drives the mounting plate 77 away from the slide plate 26 until the connecting rod 74 gripped by the first pneumatic gripper 29 and the second pneumatic gripper 30 is located between the transfer platform 52 and the pressure plate 51. Then, the second power source 27 drives the slide plate 26 to move vertically downward, placing the connecting rod 74 gripped by the first pneumatic gripper 29 and the second pneumatic gripper 30 on the transfer platform 52. After that, the fourth power source 55 pushes the connecting plate 54 downward. At this time, the pressure plate 51 and the vertical column 53 will follow the connecting plate 54 downward until the pressure plate 51 presses the connecting rod 74 tightly onto the transfer platform 52.

[0064] Step 7: Release the gripping of the first pneumatic gripper 29 and the second pneumatic gripper 30 on the connecting rod 74, and use the third power source 28 to push the rotating frame 35 to move the mounting plate 77 closer to the slide plate 26 until the rotating frame 35 contacts the slide plate 26. At this time, the gripping ends of the first pneumatic gripper 29 and the second pneumatic gripper 30 move out of the ring 75 of the connecting rod 74.

[0065] In the eighth step, the slide block 10 is slid on the track to the rear side of the transfer platform 52 by the first power source 16, and the push plate 14 contacts one side of the second limit rod 18. At this time, the slide block 10 corresponds to the transfer mechanism, and the first pneumatic gripper 29 and the second pneumatic gripper 30 are located at the rear side of the transfer platform 52. Then, the sliding plate 39 is pushed to move horizontally on the horizontal plate 38 by the fifth power source 42. At this time, the rack 40 at the bottom of the sliding plate 39 will drive the rotating shaft 37 to rotate through the gear 41. The rotating shaft 37 will drive the turntable 34 to rotate. The turntable 34 will drive the mounting plate 77 to rotate along the rotation axis of the rotating shaft 37 until the mounting plate 77 rotates 180 degrees along the rotation axis of the rotating shaft 37. At this time, the first pneumatic gripper 29 and the second pneumatic gripper 30 will correspond to the two rings 75 in the connecting rod 74 on the transfer platform 52, respectively.

[0066] As the slide block 10 slides from the front side of the transfer platform 52 to the rear side of the transfer platform 52, the suspension plate 19 on the push plate 14 will press the third limiting plate 23 downward, and the first compression spring 22 will be compressed. When the push plate 14 and the suspension plate 19 pass the third limiting plate 23, the first compression spring 22 will push the rectangular plate 21 to move the third limiting plate 23 upward back to its original position.

[0067] In the ninth step, the third power source 28 pushes the rotating frame 35 to move the mounting plate 77 horizontally away from the slide plate 26 until the contact block 31 contacts one side of the connecting rod 74. At this time, the gripping ends of the first pneumatic claw 29 and the second pneumatic claw 30 will be located in the two rings 75 in the connecting rod 74 respectively. Then, the gripping ends of the first pneumatic claw 29 and the second pneumatic claw 30 support the inner wall of the rings 75 from the top and bottom to complete the gripping of the connecting rod 74. After that, the fourth power source 55 pushes the connecting plate 54 to move upward, so that the pressure plate 51 separates from the connecting rod 74. Then, the third power source 28 pushes the rotating frame 35 to move the mounting plate 77 closer to the slide plate 26 until the rotating frame 35 contacts the slide plate 26. After that, the fifth power source 42 makes the mounting plate 77 rotate 180 degrees in the opposite direction along the rotation axis of the rotating shaft 37.

[0068] Step 10: Using the first power source 16, the slide 10 slides in the opposite direction on the track until it reaches the front of the turntable 52. At this point, the connecting rod 74 can be flipped. Then, using the first power source 16, the slide 10 slides on the track towards the grinding device 3 until the connecting rod 74 is moved to the position corresponding to the grinding wheel 2. At this point, the moving plate 32 in the slide 10 is located between the fixed plate 72 and the side plate 71, and the rollers 73 on the fixed plate 72 and the side plate 71 are in contact with the moving plate 32. Then, the third power source 28 pushes the rotating frame 35 to move the mounting plate 77 away from the slide plate 26. At this point, the connecting rod 74 gripped by the first air gripper 29 and the second air gripper 30 will approach the grinding wheel 2 of the grinding device 3. At this point, the other side of the connecting rod 74 can be ground by the grinding wheel 2 of the grinding device 3.

[0069] As the slide block 10 slides from the rear side of the transfer platform 52 to the front side of the transfer platform 52, the suspension plate 19 on the push plate 14 will pass the third limiting plate 23. When the suspension plate 19 passes the third limiting plate 23, the suspension plate 19 will press the third limiting plate 23 downward. After the suspension plate 19 passes the third limiting plate 23, the first compression spring 22 will push the rectangular plate 21 to move the third limiting plate 23 upward back to its original position.

[0070] In the eleventh step, after the two sides of the connecting rod 74 are polished, the slide block 10 is moved along the track towards the unloading plate 4 by the first power source 16 until the connecting rod 74 gripped by the first air gripper 29 and the second air gripper 30 moves to the top of the unloading plate 4. Then, the slide plate 26 is driven vertically downward by the second power source 27 to place the connecting rod 74 gripped by the first air gripper 29 and the second air gripper 30 on the unloading plate 4 and release the gripping of the connecting rod 74 by the first air gripper 29 and the second air gripper 30. At this time, the connecting rod 74 will slide downward along the inclined direction of the unloading plate 4 to complete the unloading. After the unloading is completed, the second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth and eleventh steps are repeated in sequence to realize the automatic polishing and flipping of the connecting rod 74. In the repeated third step, there is no need to adjust the position of the second air gripper 30 again.

[0071] When the length of the next batch of connecting rods 74 that need to be polished changes, simply repeat the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, and eleventh steps in sequence. This device can adapt to polishing connecting rods 74 of different lengths and is simple and convenient to use.

[0072] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
