[0002] A gear shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have a different diameter. The parts that perform rotating motion in the machine are mounted on the shaft. When using a gear shaft assembly machine to assemble the gear shaft to the equipment, a loading mechanism is required to push the gear shaft into the corresponding position of the equipment, and then the gear shaft assembly machine fixes the gear shaft.

[0003] The feeding mechanism is one of the necessary equipment for modern chemical industry, pharmaceutical industry, food industry, metallurgy, building materials industry, agricultural and sideline industries, etc. It provides work efficiency, accurate transportation, reliable quality and durability. In the feeding process, the raw materials are completely free from moisture, pollution, foreign matter and loss, which realizes the self-transportation of the feeding process, avoids the danger of high-altitude feeding, reduces labor intensity and improves production efficiency. It is one of the necessary equipment for civilized production of modern enterprises.

[0004] Before assembling the gear shaft, the surface of the gear shaft must be kept clean to prevent dust, oil and other pollutants from affecting the assembly accuracy. In the prior art, most gear shafts are stacked in a placement box on one side of the feeding mechanism, and the gear shafts are transmitted one by one to the assembly machine through the feeding mechanism. The robot inside the assembly machine takes the gear shaft, but when the gear shafts are placed in the placement box, collisions will occur between the gear shafts, and some iron filings will be produced on the surface of some gear shafts, thereby affecting the assembly accuracy of the gear shaft and the production quality of the equipment. Summary of the invention

[0058] The working principle of the present invention is as follows: when the staff uses the feeding mechanism to transfer the gear shaft to the assembly machine, the staff puts the gear shaft into the placement bin 2, and then starts the drive motor 14 to drive the drive shaft 15 to rotate clockwise, thereby driving the first drive bevel gear 16 and the second drive bevel gear 17 to rotate;

[0059] When the second driving bevel gear 17 rotates, the second driving bevel gear 17 is meshed and connected with the first transmission bevel gear 19, so the first transmission bevel gear 19 rotates, thereby driving the first transmission shaft 18 to rotate, and the first transmission shaft 18 is respectively connected to one end of the input shaft 20 and one end of the second transmission shaft 41 through a synchronous belt, so one end of the input shaft 20 and one end of the second transmission shaft 41 rotate, and due to the setting of the first one-way bearing 21, the other end of the input shaft 20 does not rotate;

[0060] When the second transmission shaft 41 rotates, the second transmission bevel gear 42 is driven to rotate, and the second transmission bevel gear 42 is meshed and connected with the first linkage bevel gear 12, so the first linkage bevel gear 12 rotates, thereby driving the first linkage shaft 11 to rotate, and the first linkage shaft 11 is connected with the limit shaft 8 through a synchronous belt, so the limit shaft 8 rotates, and the outer wall of the limit shaft 8 is threadedly connected with the inner wall of the slider 10, and the thread groove on the outer wall of the limit shaft 8 is a reciprocating thread groove, so the slider 10 moves back and forth, thereby driving the push plate 9 to move back and forth, so that one end of the push plate 9 moves to one end of the push chute 13 and then resets;

[0061] When the first driving bevel gear 16 rotates, the first driving bevel gear 16 is meshed with the movable bevel gear 7, so the movable bevel gear 7 rotates, thereby driving the movable shaft 6 to rotate, and the outer wall of the movable shaft 6 is threadedly connected with the inner wall of the push plate 5, so the push plate 5 moves upward, and the upper end of the push plate 5 pushes a group of gear shafts to move, so that a group of gear shafts fall to the upper end of the guide plate 4, and fall from the upper end of the guide plate 4 to the lower end of the guide plate 4, and at the same time, the push plate 9 is moving back and forth, driving the gear shaft to adjust, and after the push plate 9 is reset, one end of the gear shaft falls into the push chute 13;

[0062] When one end of a set of gear shafts falls into the push chute 13, the drive motor 14 drives the drive shaft 15 to change the rotation direction, so that the drive shaft 15 rotates counterclockwise, thereby driving the first drive bevel gear 16 and the second drive bevel gear 17 to change the rotation direction, and then driving the push plate 5 to reset. At the same time, the second drive bevel gear 17 drives the first transmission shaft 18 to rotate, and the first transmission shaft 18 drives one end of the second transmission shaft 41 to rotate. Due to the setting of the second one-way bearing 43, the other end of the second transmission shaft 41 does not rotate;

[0063] When the push plate 5 is reset, the driving motor 12 drives the driving shaft 15 to rotate clockwise, thereby driving the push plate 9 to move. The push plate 9 pushes a set of gear shafts to a set of placement grooves 26 and then resets. At the same time, the other set of gear shafts falls into the push chute 13.

[0064] When the push plate 9 is reset, the driving motor 12 drives the driving shaft 15 to rotate counterclockwise, thereby driving the first transmission shaft 18 to rotate, and the first transmission shaft 18 drives the input shaft 20 to rotate. One end of the input shaft 20 is connected to the input end of the speed change gear box 22. The speed change gear box 22 reduces the speed, and the output end of the speed change gear box 22 is connected to the output shaft 23, thereby driving the output shaft 23 to rotate, and then driving the turntable 25 to rotate with the output shaft 23 as the center of the circle. The rotation angle of the turntable 25 is ninety degrees. The turntable 25 drives a group of gear shafts to move, and the turntable 25 drives a group of gear shafts to enter the inside of the protective cover 28 from the feed inlet;

[0065] When the input shaft 20 rotates, the input shaft 20 is connected to the mounting shaft 36 through a synchronous belt, so the mounting shaft 36 rotates, thereby driving the fan to rotate, so that airflow is generated inside the bellows 35, and the airflow flows to the air outlet plate 31 through the air outlet pipe 37 for discharge. When the gear shaft passes through the feed port 29, the air outlet plate 31 blows the airflow to the surface of the gear shaft, blows and cleans the iron filings attached to the outer wall of the gear shaft, or blows away the iron filings attached to the outer wall of the gear shaft, thereby reducing the adhesion effect of the iron filings on the outer wall of the gear shaft;

[0066] When airflow is generated inside the bellows 35 and discharged through the air outlet pipe 37, negative pressure is generated in the air inlet pipe 38, and the negative pressure is transmitted to the inside of the dust collecting box 39, so that the dust collecting pipe 40 generates suction force, and the suction force is transmitted to the dust collecting plate 32. When the gear shaft moves at the lower end of the dust collecting plate 32, the dust collecting plate 32 absorbs the iron filings remaining on the surface of the gear shaft, further improving the cleanliness of the gear shaft surface. In the process of the movement of the gear shaft, the bottom end of the gear shaft contacts the auxiliary plate 34, and both ends of the auxiliary plate 34 are inclined, so as to lift the horizontal position of the gear shaft upward, so that the outer wall of the gear at the upper end of the gear shaft is separated from the outer wall of the upper end of the turntable 25, further improving the cleaning effect of the gear shaft surface.

[0067] After the driving motor 14 drives the driving shaft 15 to rotate clockwise and counterclockwise for many times, the turntable 25 drives a set of gear shafts to move to the inside of the clamping seat 47, and a set of gear shafts are meshed and connected with the toothed plate 33 during the movement, so a set of gear shafts rotate, thereby adjusting the gear angle at the upper end of the gear shaft;

[0068] When a group of gear shafts move into the clamping seat 47, the second transmission shaft 41 rotates, driving the third transmission bevel gear 44 to rotate, and the third transmission bevel gear 44 is meshed and connected with the second connecting bevel gear 46, so the second connecting bevel gear 46 rotates, thereby driving the second connecting shaft 45 to rotate, and the outer wall of the second connecting shaft 45 is threadedly connected to the inner wall of one end of the clamping seat 47, so the clamping seat 47 is displaced, thereby driving a group of gear shafts to displace, and the clamping seat 47 drives the gear shaft to enter the assembly machine, and the robot inside the assembly machine takes the gear shaft.
