Description

Technical Field

[0001] This invention relates to the field of assembly machinery, and more specifically to a corrugated pad oil seal assembly machine. Background Technology

[0002] In the field of mechanical assembly, the valve seat and oil seal are key sealing and buffering components, and their assembly quality directly affects the operational stability and service life of the motor. Currently, the industry still generally uses manual operation for the assembly of valve seats, oil seals, and rotors to the housing. The specific process is as follows: the operator manually picks up the valve seat and places it in the preset position on the housing, presses the oil seal into the corresponding slot on the rotor using a manual pressing tool, and finally manually moves the rotor to the housing for assembly and fixation.

[0003] This traditional process has the following significant drawbacks:

[0004] (1) When manually placing the wave pad, the operator may miss it due to fatigue or negligence, which may lead to sealing failure or wear of parts during the operation of subsequent equipment.

[0005] (2) During the manual pressing of the oil seal, it is impossible to accurately control the pressure and direction, which can easily lead to uneven pressing depth and skew, resulting in oil leakage and increased after-sales maintenance costs.

[0006] (3) The rotor and the casing are mostly heavy metal parts. Manual handling and assembly not only consume physical strength, but also make it difficult to ensure the assembly alignment accuracy. Long-term operation can easily lead to muscle strain of the operator.

[0007] (4) Single process relies on manual operation, which is greatly affected by the skill level and physical condition of the personnel, making it difficult to achieve standardized mass production and restricting the overall production line capacity improvement.

[0091] An embodiment of the present invention provides a corrugated pad oil sealing assembly machine with the following operating procedure:

[0092] (1) Preliminary preparation. The operator places the corrugated pad on the corrugated pad top material conforming jig 49 of the corrugated pad discharge assembly 17 to ensure neat fit; put the oil seal into the oil seal cylinder 30 and stack them neatly; put the rotor into the rotor loading position 36 of the left station and the machine housing into the machine housing loading position 39 of the right station to ensure alignment with the guide rail; check the air pressure (0.4-0.6MPa) of the air source triplet 44, the power supply of PLC 7 and the working status of safety light curtain 10.

[0093] (2) Material pretreatment and material handling. The oil seal guide fixture 16 is placed on the upper end of the rotor. The oil seal pushed out by the oil seal discharge cylinder 29 is taken out from below the oil seal cylinder 30 and placed into the oil seal guide fixture 16. After the oil seal is discharged, the sensor senses the signal and the oil seal discharge cylinder 29 automatically returns to its original position. At the same time, the wave pad picking module 11 is started: the X-axis 12 of the wave pad picking module drives the Z-axis 13 of the wave pad picking module to move above the wave pad discharge assembly 17. The Z-axis 13 of the wave pad picking module moves down, and the wave pad lifting servo module 21 lifts the wave pad to the picking position.

[0094] When the vacuum generator 14 is working, the vacuum wave pad suction cup 15 generates negative pressure to suck up the wave pad. The negative pressure value of the vacuum generator 14 is used to determine whether it is sucked up. The wave pad picking module X-axis 12 moves to the secondary material presence sensor 43 to confirm the presence of the wave pad.

[0095] (3) Initial assembly and start-up. The operator presses button switch 18 with both hands to start the equipment. The rotor front and rear pusher cylinders 37 push the rotor loading position 36 along the rotor linear guide rail 34 to the oil seal pressing position, and the housing front and rear pusher cylinders 38 push the housing loading position 39 along the housing linear guide rail 35 to the wave pad assembly position. After the housing is in place, the housing side pressure cylinder 19 and clamping cylinder extend to clamp the housing from both sides to prevent displacement.

[0096] The X-axis 12 and Z-axis 13 of the wave cushion picking module 11 work together to move the wave cushion to the top of the machine housing. The Z-axis 13 of the wave cushion picking module moves down to place the wave cushion into the preset slot in the machine housing. Then, the vacuum is released, and the module returns to the initial picking position. At the same time, the oil seal pressing electric cylinder 1 drives the oil seal pressing fixture 26 to move down, pressing the oil seal along the oil seal guide fixture 16 into the preset position of the rotor. The first pressure sensor 3 monitors the pressing force in real time. After the pressing is completed, the oil seal pressing electric cylinder 1 resets.

[0097] (4) Mistake-proof inspection and assembly preparation. The front and rear pusher cylinders 37 of the rotor drive the rotor back to the operator's material picking position, remove the oil seal guide fixture 16 and put it into the oil seal guide mistake-proof fixture 33. The mistake-proof sensor 32 detects that the oil seal guide fixture 16 is in place, confirming that there is no omission.

[0098] (5) Rotor and housing assembly. The operator presses the button switch 18 again with both hands, and the rotor front and rear pushing cylinders 37 push the rotor loading position 36 to the rotor picking position. The rotor picking module X-axis 8 and rotor picking module Z-axis 9 work together to grab the rotor through the rotor picking fixture 28 and transport it to the top of the housing pressing position. The stator and rotor assembly electric cylinder 2 moves down to 1-2mm above the rotor, and the rotor assembly lower lifting cylinder 20 lifts the rotor, and the rotor picking module returns to the standby position. The stator and rotor assembly electric cylinder 2 continues to press down, while the rotor assembly lower lifting cylinder 20 slowly depressurizes. The relative movement of the two presses the rotor into the housing. The second pressure sensor 4 provides feedback on the pressing force to ensure accurate positioning. After pressing is completed, the stator and rotor assembly electric cylinder 2 and the rotor assembly lower lifting cylinder 20 reset, and the housing side pressing cylinder 19 retracts.

[0099] (6) Finished product removal and recycling. The front and rear push cylinders 38 of the machine casing push the material loading position 39 of the machine casing to the finished product removal position, and the operator lifts and removes the assembled finished product. The equipment returns to the initial state, and the operator repeats steps (1)-(5) to carry out the next round of assembly.

[0100] This embodiment achieves automation of bellows, oil seal assembly, and rotor-housing assembly through the coordinated work of various systems, effectively solving problems such as omissions, uneven pressure, and high labor intensity in manual assembly, and improving product consistency and production efficiency.

[0101] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
