Technical Field

[0001] This application relates to the technical field of skeleton oil seal processing, and in particular to a skeleton oil seal trimming device. Background Technology

[0002] The skeleton oil seal is a typical example of an oil seal, and the term "oil seal" generally refers to the skeleton oil seal. The function of an oil seal is typically to isolate the lubricated components in a transmission system from the external environment, preventing lubricant leakage. The skeleton acts like the reinforcing steel in a concrete structure, providing reinforcement and maintaining the seal's shape and tension.

[0003] After the skeleton oil seals are produced, the quality inspection department will collect and process the unqualified oil seals, and some rough edges will be trimmed manually.

[0004] Manual pruning takes a lot of time and is inefficient. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0026] This application discloses a skeleton oil seal trimming device.

[0027] refer to Figure 1 A skeleton oil seal trimming device includes a main body 1, on which a support and rotation mechanism 2, a trimming mechanism 3, a transfer mechanism 4, and a braking mechanism 5 are provided. The transfer mechanism 4 transfers the skeleton oil seal to the support and rotation mechanism 2, which drives the skeleton oil seal to rotate. The trimming mechanism 3 trims the rotating skeleton oil seal. After the trimming is completed, the skeleton oil seal stops rotating under the action of the support and rotation mechanism 2 and the braking mechanism 5. Finally, the transfer mechanism 4 transfers the trimmed skeleton oil seal out of the support and rotation mechanism 2.

[0028] refer to Figure 1 and Figure 2 The supporting rotation mechanism 2 includes a rotating block 21 rotatably connected to the main body 1, and the rotating block 21 is provided with a clearance groove 211; a first motor 22 is connected to the main body 1, and the output shaft of the first motor 22 is connected to the rotating block 21.

A pressing block 233 is rotatably connected to the moving block 232.

[0030] After the oil seal is engaged with the rotating block 21, the first cylinder 231 is started. The piston rod of the first cylinder 231 drives the moving block 232 to move closer to the rotating block 21. The moving block 232 drives the pressing block 233 to move, so that the pressing block 233 presses against the oil seal located on the rotating block 21. The first motor 22 is started. The output shaft of the first motor 22 drives the rotating block 21 to rotate. Because the pressing block 233 presses against the oil seal located on the rotating block 21, the rotating block 21 will drive the oil seal to rotate, and the pressing block 233 will also rotate with the oil seal.

[0034] Start the fifth motor 372. The output shaft of the fifth motor 372 drives the first rotating shaft 371 to rotate. The first rotating shaft 371 drives the cutter holder 33 to rotate, and selects the appropriate trimmer 34 to align with the oil seal skeleton. Start the third motor 351. The output shaft of the third motor 351 drives the second lead screw 352 to rotate. The second lead screw 352 drives the first moving block 31 to slide on the main body 1. Start the fourth motor 361. The output shaft of the fourth motor 361 drives the third lead screw 362 to rotate. The third lead screw 362 drives the second moving block 32 to move on the first moving block 31. The first rotating shaft 371 on the second moving block 32 drives the cutter holder 33 to move. The cutter holder 33 drives the trimmer 34 to move, so that the trimmer 34 moves to a position where it can trim the oil seal skeleton. In this way, when the rotating block 21 drives the oil seal skeleton to rotate, the trimmer 34 will cut and trim the oil seal skeleton.

The piston rod of the third cylinder 52 drives the adjusting block 53 to move, and the adjusting block 53 drives the brake block 54 to move, so that the brake block 54 abuts against the oil seal.

[0038] When brake block 54 needs maintenance after prolonged use, the sixth motor 622 is started. The output shaft of the sixth motor 622 drives the second rotating shaft 621 to rotate, the second rotating shaft 621 drives the rotating block 61 to rotate, the rotating block 61 drives the third cylinder 52 to rotate, and the adjusting block 53 on the third cylinder 52 drives the brake block 54 to rotate, so that the brake block 54 is rotated to a position that is convenient for the operator to maintain.

A first adjusting block 42 is slidably connected to the rodless cylinder 41. A second cylinder 43 is mounted on the first adjusting block 42, with its cylinder body fixedly mounted on the first adjusting block 42. A second adjusting block 44 is connected to the piston rod of the second cylinder 43.

The third adjusting block 46 drives the two fourth adjusting blocks 47 to move, so that the fourth adjusting block 47 that does not clamp the skeleton oil seal is aligned with the rotating block 21. Then the second motor 494 is started, so that the three clamping blocks 48 clamp the repaired skeleton oil seal. Then the rodless cylinder 41 is started, so that the repaired skeleton oil seal is separated from the rotating block 21. Then, the rotary cylinder 45 is activated. The piston rod of the rotary cylinder 45 drives the third adjusting block 46 to rotate, and the third adjusting block 46 drives the two fourth adjusting blocks 47 to rotate, so that the fourth adjusting block 47 holding the skeleton oil seal that needs to be repaired is aligned with the rotary block 21. Then, the rodless cylinder 41 is activated to engage the skeleton oil seal that needs to be repaired with the rotary block 21. Finally, the rodless cylinder 41 and the second cylinder 43 are activated to transfer the repaired skeleton oil seal out of the main body 1.
