Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a double gear press-fitting device. Background Technology

[0002] Double gears are widely used in various engineering machinery such as gearboxes. A double gear typically consists of a large gear and a small gear, with the small gear press-fitted and fixed to the large gear. Patent number CN202120861800.8 discloses a double gear tooth-fitting tooling, including an upper plate, a lower plate, support columns, a large gear, and a small gear. The upper and lower ends of the support columns are fixed to the upper and lower plates respectively. Each support column has a support spring on its outer side, with the upper and lower ends of the springs abutting against the upper and lower plates respectively. A tensioning device is fixed in the middle of the upper plate, and the small gear is fitted outside the tensioning device. A small gear tooth-fitting device is mounted on one side of the lower bottom surface of the upper plate. The large gear is fixed in the middle of the lower plate, and a large gear tooth-fitting device is mounted on one side of the upper bottom surface of the lower plate. The tip of the small gear tooth-fitting device can pop out and press into the tooth groove of the small gear, and the tip of the large gear tooth-fitting device can pop out and press into the tooth groove of the large gear. A tensioning device release block is provided in the middle of the lower plate, which can release the tensioning device after the small gear is pressed into the large gear. The entire assembly is placed on the press, and the press head presses against the upper surface of the plate and moves downward, causing the pinion 10 to move downward until it presses into the middle of the large gear 9. When the pinion 10 is pressed into the designed position of the large gear 9, the tensioning device 6 of the lower plate 2 releases the mandrel 61 of the tensioning device 6, causing the tension sleeve of the tensioning device 6 to loosen. The press head moves upward, and the support spring 4 fixes the upper plate 1 back to contact with the limit nut 3. Because the tension sleeve 62 of the tensioning device 6 has been loosened, the pinion 10 disengages from the upper plate 1 and connects with the large gear to form a double gear assembly. This tooling requires manual loading, which is cumbersome to operate, and subsequent pressing can only be carried out after the current product has been pressed and removed, resulting in low efficiency. Therefore, this utility model proposes a double gear pressing device. Utility Model Content

A first gripper 13 is connected to the bottom of the mounting plate. A U-shaped plate is fixed to the front of the mounting plate. The second lifting cylinder 12 is connected to the top of the U-shaped plate 14. A rotating shaft is vertically mounted on the top of the U-shaped plate 14. The first gripper 13 is fixed to the bottom of the rotating shaft. A servo motor mounted on the mounting plate is connected to the top of the rotating shaft via a pulley 15 and a belt. The servo motor drives the belt to rotate, thereby rotating the shaft and adjusting the angle of the pinion. The pinion is not inside the linear vibration track 7. The thickness of the receiving plate 9 is half the thickness of the linear vibration track 7. The pinion enters the linear vibration track 7 from the vibrating plate 6 and is fed forward. After the foremost pinion enters the receiving groove 10, the first lifting cylinder 8 lifts the receiving plate 9 upward, raising the pinion. The left end of the receiving plate 9 blocks the remaining pinions in the linear vibration track 7. The upper half of the pinion on the receiving plate 9 is exposed. The first gripper 13, driven by the transverse translation module 11 and the second lifting cylinder 12, clamps and transports the pinion on the receiving plate 9 to the large gear in the fixture 3 below it.

[0021] The tray loading and unloading mechanism includes two first conveyor belts 16 and two second conveyor belts 17 that are connected and aligned. The transfer mechanism is located above the side of the second conveyor belt 17 closest to the first conveyor belt 16. A material picking station is located below the transfer mechanism.

A tray mechanism is located on the outer side of each of the two second conveyor belts 17. The tray mechanism includes two side plates vertically mounted on the machine base 1. A horizontal plate is fixed between the two side plates. A support plate 21 is slidably connected to the horizontal plate via a slide rail perpendicular to the second conveyor belt 17. The trays are driven by a translation cylinder 22. Multiple trays are stacked on the support plate 21. Multiple positioning posts 23 are located on both sides of the upper end face of the tray.

[0023] The working process of this utility model is as follows: A carrier tray carrying a gear is placed on the first conveyor belt 16. The first conveyor belt 16 transports the carrier tray to the left to the picking station. The two stops 18 are raised to position the carrier tray. The second gripper 27, driven by the planar moving module 24 and the third lifting cylinder 25, picks up the large gear in the carrier tray and transports it to the fixture 3 on the front side of the turntable 2. During this process, the rotary cylinder 26 drives the second gripper 27 to rotate to adjust the angle of the large gear. The turntable 2 rotates counterclockwise under the drive of the servo motor. After the turntable 2 rotates 90°, the second gripper 27 continues to transport the large gear to the next fixture 3. After the turntable 2 rotates 180°, the fixture 3 carrying the large gear arrives at the small gear feeding mechanism. The small gear feeding mechanism pre-installs the small gear onto the large gear. The turntable 2 continues to rotate 90°. °, the pre-assembled gears arrive at the pressing mechanism, pressing the small gear and the large gear together. The turntable 2 continues to rotate 90°, and the second gripper 27 removes the assembled product and places it back onto the carrier. When all the products on the tray are assembled, the two stops 18 descend, and the second conveyor belt 17 transports the carrier to the storage mechanism. The lifting cylinder 20 drives the top plate 19 to lift the carrier until its positioning post 23 extends into the positioning hole of the upper carrier. The leveling cylinder drives the pallet 21 to retract. The lifting cylinder 20 continues to lift until the lower end of the bottom carrier is higher than the upper end of the pallet 21 and stops. The translation cylinder 22 drives the pallet 21 to extend, and the lifting cylinder 20 retracts. Multiple stacked carriers fall onto the pallet 21. The first conveyor belt 16 transports the next carrier with the large gear to the picking station.

[0024] The above descriptions are merely some embodiments of this utility model.
