Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and more specifically to an automatic oiling machine for torsion spring steel wires. Background Art

[0002] During the assembly process of the seat frame, some parts need to be greased. The seat frame torsion spring is a kind of seat frame component with an irregular shape. The two ends of the seat frame torsion spring are bent at a certain angle relative to the middle. The amount, uniformity, and position of grease applied to the seat frame torsion spring affect the overall performance of the seat frame. At present, the seat frame torsion spring is manually greased, and the amount, uniformity, and position of the grease are related to the working habits of the oiler. The amount and position of the oiling will be different due to differences in working habits between workers. When manually applying grease, the amount of oil applied cannot be accurately controlled. Too much oil will cause unnecessary waste, and too little oil will affect the quality of the product. At the same time, manual oiling increases the labor cost investment in production.

When the middle position magnetic switch on the rodless cylinder 631 senses that the transport plate 633 is in place, the signal is transmitted to the control cabinet, and the solenoid valve on the rodless cylinder 631 is controlled to be de-energized through the control cabinet. At this time, under the action of inertia, the transport plate 633 will continue to move. At the same time, the piston rod of the second lifting cylinder 721 is controlled to extend downward. When the lower position magnetic switch on the second lifting cylinder 721 senses that the transport plate 633 is in place, the signal is transmitted to the control cabinet, and the solenoid valve of the second lifting cylinder 721 is controlled to be de-energized through the control cabinet. At this time, the The piston rod just blocks the side of the material transport plate 633, and makes the torsion spring 10 just face the two proximity sensors 5 on the oiling position. The two proximity sensors 5 transmit the acquired torsion spring 10 signal to the control cabinet, and the control cabinet controls the first lifting cylinder 712 to drive the upper oiling block 713 to move downward. When the lower position magnetic switch on the first lifting cylinder 712 senses that the material transport plate 633 is in place, the signal is transmitted to the control cabinet, and the control cabinet controls the solenoid valve of the first lifting cylinder 712 to cut off the power. Then, the control cabinet controls the flow distribution valve 733 to open for oil delivery. After a certain period of time, the control cabinet controls the flow distribution valve 733 to close, and delays for a certain period of time. Then, the control cabinet controls the first lifting cylinder 712 to move and drive the upper oiling block 713 moves upward. When the upper position magnetic switch on the first lifting cylinder 712 senses that the material transport plate 633 is in place, the signal is transmitted to the control cabinet, and the solenoid valve of the first lifting cylinder 712 is controlled to be de-energized through the control cabinet. At the same time, the piston rod of the second lifting cylinder 721 is controlled to extend upward. When the upper position magnetic switch on the second lifting cylinder 721 senses that the material transport plate 633 is in place, the signal is transmitted to the control cabinet, and the solenoid valve of the second lifting cylinder 721 is controlled to be de-energized through the control cabinet, and the solenoid valve on the rodless cylinder 631 is controlled to be energized, driving the material transport plate 633 and the two material dividing and oiling blocks 634 on the material transport plate 633 to move toward the material fetching position. When the front position magnetic switch on the rodless cylinder 631 senses that the material transport plate 633 is in place,The signal is transmitted to the control cabinet, which controls the solenoid valve on the rodless cylinder 631 to cut off the power. Under the action of inertia, the material transport plate 633 will continue to move until it contacts the hydraulic buffer of the buffer positioning block 9 on the material picking position and is positioned at the screw position. At this time, the torsion spring 10 is just facing the two proximity sensors 5 on the material picking position. The two proximity sensors 5 transmit the acquired torsion spring 10 signal to the control cabinet, and the control cabinet controls the entire equipment to be in a stopped state. The torsion spring 10 that has been oiled is taken out. When the two proximity sensors 5 on the material picking position detect that there is no torsion spring 10 signal and the protective grating 8 is not blocked, the control cabinet will control the entire equipment to move to repeat the above operation steps to carry out the oiling process of the next torsion spring 10. It should be noted that: when dividing materials, the two dividing oiling blocks 634 on the material transport plate 633 push the corresponding supporting blocks 621 respectively, so that the two ends of the torsion spring 10 at the bottom of the material storage plate 611 fall into the corresponding storage grooves 6341 respectively. When the dividing oiling block 634 leaves the supporting block 621, the supporting block 621 returns to its initial state under the action of the spring and keeps the materials again; when applying oil, after the dividing oiling block 634 moves into place, the two upper oiling blocks 713 move downward respectively, so that their lower end faces are pressed against the upper end faces of the corresponding dividing oiling blocks 634 to form an oil injection cavity, and the multiple upper oil outlets 71311 and the multiple lower oil outlets 63411 are evenly distributed up and down, and the storage grooves 6341 are blocked by the blocking part 7132; when taking materials, after the dividing oiling block 634 moves into place, the torsion spring 10 that has been oiled is taken out.
