Description

Technical Field

[0001] The utility model belongs to the technical field of gear shaft production, in particular to a gear shaft feeding mechanism of a gear shaft assembly machine. Background Art

[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. When using a gear shaft assembly machine to assemble the gear shaft to a device, a feeding mechanism is required to push the gear shaft into the corresponding position of the device, and then the gear shaft assembly machine fixes the gear shaft. When the existing gear shaft assembly machine feeding mechanism pushes the gear shaft, if the installation space of the gear shaft is small and the clamp interferes with the device and cannot be inserted, only the rotating shaft part of the gear shaft can be pushed into the device, while the gear part clamped by the clamp cannot be pushed in, making the installation more cumbersome.

[0003] At present, my country's patent CN202221467657.5 discloses a gear shaft feeding mechanism of a gear shaft assembly machine, comprising: a fixed plate and a push rod, wherein four electric screw slides for providing clamping force are fixed on the side of the fixed plate, and the four electric screw slides are evenly arranged along a circle of the fixed plate, and the four electric screw slides are all transmission-connected with elastically retractable gas springs; when in use, the telescopic cylinder pushes the device forward as a whole through the fixed plate, and when the clamping plate hits the equipment and cannot move, the gas spring contracts, and the push rod continues to push the gear shaft forward, and the gear part of the gear shaft slides forward along the clamping plate until the gear part of the gear shaft is inserted into the corresponding position of the equipment, so that the gear shaft can be installed in place at one time, and there is no need to push the gear shaft multiple times, and during the installation process, the gear part of the gear shaft is always clamped and guided by the clamping plate, and the installation accuracy is high.

[0004] In the prior art, the gas spring is provided so that the gear shaft can be installed in one step, but there are still certain deficiencies in the production process: the gear shaft feeding mechanism not only has the part for clamping the gear shaft, but also needs to transfer the gear shaft to the clamping point. In the prior art, this part is usually transported by an ordinary conveyor belt. In this process, there are few limit points between the gear shaft and the conveyor belt. Therefore, it is easy to deviate, tip over, flip, etc. during the feeding process, which is not easy to clamp later. However, the prior art lacks processing settings for it. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a gear shaft feeding mechanism of a gear shaft assembly machine.

[0006] The utility model uses a feeding belt and a limiting tooth in conjunction with a bending plate and an elastic arc plate to effectively limit the gear shaft during the feeding process. When stable feeding is completed, correction processing can be performed when the gear shaft is offset, so that the subsequent clamping of the gear shaft can be smoother, thereby improving work efficiency.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gear shaft feeding mechanism of a gear shaft assembly machine, including a feeding rack and a feeding belt, a feeding belt is provided for transmission inside the feeding rack, a plurality of limit teeth are evenly provided on the outer surface of the feeding belt along the contour line direction, two bending plates are symmetrically slidably provided on both sides above the feeding belt, a plurality of guide plates are provided on the upper end surfaces of the two bending plates, a hemispherical plate is provided on the top end surface of each guide plate, and a wheel shaft frame is slidably provided on one side of the feeding rack. The provision of a plurality of limit teeth enables the gear shaft to be driven smoothly to complete the transmission process, and the provision of the two bending plates enables the optical axis end of the gear shaft to be lifted, thereby improving the stability during transmission.

[0008] Preferably, a plurality of transmission shafts are provided for transmission inside the feed belt, a driving motor is provided on one side of the transmission shaft on the end face of the feed frame, and an output end of the driving motor is connected to the end face of the transmission shaft.

[0009] Preferably, a plurality of second push cylinders are arranged on the end surfaces of the two bending plates, and a connecting plate is connected to the output end of each of the second push cylinders, a plurality of elastic arc plates are arranged on the end surface of the connecting plate, and a spherical rod is arranged on the outer end surface of each of the elastic arc plates. The arrangement of the elastic arc plates and the spherical rod enables the offset gear shaft to be centered and corrected, avoiding offset and improving the subsequent clamping efficiency.

[0010] Preferably, the lengths of the plurality of elastic arc plates increase one by one in the longitudinal direction. The gradually increasing elastic arc plates can avoid the situation where the tooth surface axis is overcorrected.

[0011] Preferably, a supporting inclined plate is connected between each of the elastic arc plates and the connecting plate. The provision of the supporting inclined plate effectively improves the strength of the elastic arc plate.

[0012] Preferably, a plurality of guide grooves are provided on adjacent end surfaces of the two bending plates.

[0013] Preferably, a plurality of first push cylinders are arranged on the side wall of the feeding rack, and the output end of each of the first push cylinders is connected to the bottom of the bending plate. A third push cylinder is arranged on one side of the bending plate below the axle frame, and the output end of the third push cylinder is connected to the axle frame.

[0014] In summary, compared with the prior art, the beneficial effects of this solution are:

[0015] The utility model arranges the feeding belt, the limiting teeth, the bending plate, the hemispherical plate, etc., so that the gear shaft can be smoothly driven by the feeding belt to complete the transmission process. The optical axis surfaces at both ends can be lifted, which effectively avoids the occurrence of the gear shaft slipping and tipping, making the subsequent gear shaft clamping smoother and improving the processing efficiency.

[0016] The utility model arranges the connecting plate, the elastic arc plate and the spherical rod, so that the gear shaft will not tip over, and the gear shaft with a certain offset can be centered and adjusted, which effectively improves the subsequent clamping efficiency and improves the production efficiency.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0025] refer to Figure 1-7 A gear shaft feeding mechanism of a gear shaft assembly machine includes a feeding rack 10 and a feeding belt 16. The feeding belt 16 is provided for transmission inside the feeding rack 10. A plurality of limiting teeth 21 are evenly provided on the outer surface of the feeding belt 16 along the contour line direction. Two bending plates 15 are symmetrically slidably provided on both sides above the feeding belt 16. A plurality of guide plates 17 are provided on the upper end surfaces of the two bending plates 15. A hemispherical plate 25 is provided on the top end surface of each guide plate 17. A wheel shaft frame 14 is slidably provided on one side of the feeding rack 10.

[0026] When the gear shaft needs to be fed, the staff can place the gear shaft on the outer surface of the feeding belt 16. The multiple limiting teeth 21 arranged on the outer surface of the feeding belt 16 will fit with the tooth surface of the gear shaft, thereby limiting the gear shaft and preventing the gear shaft from shaking too much. Then the feeding belt 16 will transmit the gear to one side. During the transmission of the gear shaft, the two bending plates 15 will move upward, so that the hemispherical plate 25 above the bending plate 15 will contact the outer cylindrical surface of the gear shaft end, thereby supporting the shaft ends on both sides of the gear shaft to prevent the gear shaft from tilting and overturning during movement. In this relationship, the spacing between the two bending plates 15 is greater than the thickness of the tooth surface of the gear shaft, so that the optical axis ends on both sides of the gear shaft can fit with the arc surface of the hemispherical plate 25, and the arc surface of the hemispherical plate 25 is smoothed to ensure that the gear shaft slides smoothly on the arc surface of the hemispherical plate 25, thereby improving the stability during transmission.

[0027] The feeding belt 16 will transport the gear shaft toward the axle frame 14. When the gear shaft moves to the end of the feeding belt 16, the axle frame 14 will move upward. The upper end faces of the axle frame 14 are open on both sides, and the optical axis surfaces at both ends of the gear shaft can be limited, so that the gear shaft can be connected. An assembly machine can be set on one side of the axle frame 14, and the assembly machine can clamp and install the gear shaft on the axle frame 14.

[0028] refer to Figure 4-5 7. A plurality of second push cylinders 12 are arranged on the end surfaces of the two bending plates 15. A connecting plate 18 is connected to the output end of each second push cylinder 12. A plurality of elastic arc plates 19 are arranged on the end surface of the connecting plate 18. A spherical rod 23 is arranged on the outer end surface of each elastic arc plate 19.

[0029] When the gear shaft is transmitted above the feed belt 16, the gear shaft will have a certain lateral deviation during the movement. At this time, the output end of the second push cylinder 12 will push the connecting plate 18 to move, thereby pushing multiple elastic arc plates 19 and the spherical rod 23 to move outward. The arc surface of the spherical rod 23 will fit on the end surfaces on both sides of the tooth surface shaft, thereby limiting and adjusting the two sides of the gear shaft, so that the gear shaft can always be centered to complete the transmission process. In this relationship, the elastic arc plate 19 is made of elastic rubber material, which can bend by itself when limiting the gear shaft or absorb the vibration generated by the movement of the gear shaft, thereby ensuring the stable movement of the gear shaft.

[0030] refer to Figure 4 , 7 The lengths of the multiple elastic arc plates 19 increase one by one along the longitudinal direction.

[0031] The elastic arc plate 19 on each connecting plate 18 becomes longer as it moves toward the wheel axle frame 14, so that when the two ends of the gear shaft are adjusted for limit, centering can be completed with multi-level progressive adjustment to avoid the gear shaft from overcorrecting and tipping over.

[0032] refer to Figure 4 , 7 A supporting inclined plate 20 is connected between each elastic arc plate 19 and the connecting plate 18 .

[0033] The provision of the supporting inclined plate 20 can improve the strength of the elastic arc plate 19 and prevent the elastic arc plate 19 from being bent and deformed to excessive degrees.

[0034] refer to Figure 1 , 4 -5, a plurality of transmission shafts 22 are provided for transmission inside the feeding belt 16, a driving motor 26 is provided on one side of the transmission shaft 22 on the end surface of the feeding frame 10, and an output end of the driving motor 26 is connected and provided on the end surface of the transmission shaft 22.

[0035] The two transmission shafts 22 and the transmission wheels at both ends thereof can support and transmit the feeding belt 16. The outer surface of the transmission wheel is in contact with the inner surface of the feeding belt 16. The output end of the driving motor 26 is used to drive the feeding belt 16 to rotate, thereby driving the feeding belt 16 to move.

[0036] refer to Figure 3 A plurality of first push cylinders 11 are arranged on the side wall of the feeding rack 10, and the output end of each first push cylinder 11 is connected to the bottom of the bending plate 15. A third push cylinder 13 is arranged on one side of the bending plate 15 below the axle frame 14, and the output end of the third push cylinder 13 is connected to the axle frame 14.

[0037] The output end of the first push cylinder 11 can push the bending plate 15 to move up and down, so as to better limit the optical axes at both ends of the gear shaft. The output end of the third push cylinder 13 can push the wheel axle frame 14 to move up and down, so that the wheel axle frame 14 can better connect the gear shaft. Embodiment 2:

[0038] On the basis of or different from the first embodiment, reference Figure 6 A plurality of guide grooves 24 are provided on the adjacent end surfaces of the two bending plates 15 .

[0039] The arrangement of the plurality of guide grooves 24 allows a certain amount of guiding to be performed when the two ends of the gear surface of the gear shaft are in contact with the end surface of the bending plate 15, thereby avoiding the occurrence of jamming and the like.
