Description
Technical Field
[0001] This utility model relates to the field of mechanical automated feeding equipment, and in particular to an automatic feeding mechanism for a rack and pinion support. Background Technology
[0002] In the mass production of modern automotive steering systems and mechanical transmission equipment, rack support seats are core components, and their assembly processes increasingly demand higher levels of automation. To meet the needs of efficient and precise production, various rack support seat feeding mechanisms are widely used on production lines. By replacing manual feeding and stacking operations, they reduce human error, improve overall assembly efficiency, and adapt to the continuous operation rhythm of the production line, becoming a key link in ensuring equipment assembly quality and capacity.
[0003] Currently, while existing rack and pinion support feeding mechanisms have achieved basic automation, there is still room for optimization in practical applications. On the one hand, the pushing and rotating structures of some mechanisms often use independent power drives or simple transmission coordination. The material conveying rhythm of the pushing component and the angle conversion and position transfer of the rotating component are difficult to coordinate precisely, which can easily lead to work intervals due to asynchronous actions. This not only affects the overall feeding efficiency but may also increase the risk of interference due to improper motion connection between components, requiring additional coordination control modules and increasing the complexity of the mechanism. On the other hand, the transport shafts responsible for material conveying in the mechanism often use traditional connection methods such as bolt fixing. When it is necessary to replace the transport shaft to adapt to different specifications of rack and pinion support seats, multiple fasteners need to be disassembled with special tools. The operation steps are cumbersome, which not only prolongs the equipment downtime for maintenance but also increases the operational difficulty for maintenance personnel, making it difficult to quickly respond to the production line's switching needs for different specifications of products.
[0004] In response to this technical problem, this application proposes an automatic feeding mechanism for rack and pinion support. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding mechanism for a rack and pinion support. This mechanism uses a power source to drive the transmission components, achieving precise coordination between the pushing and rotating structures, ensuring stable operation, and improving automation efficiency. At the same time, the transport shaft utilizes sliding components and elastic elements to achieve quick disassembly, enhancing the versatility of the mechanism.
[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic feeding mechanism for a rack and pinion support includes a support feeder and a base, characterized in that: a transport plate is fixedly connected to the left side of the base, the transport plate is fixedly connected to the outer wall of the support feeder on the left side, a steering support is provided on the upper side of the support feeder, a transport shaft is fixedly connected to the front side of the base, a fixing component is provided at the left end of the transport shaft, a cover plate feeder is connected to the transport shaft through the fixing component, a compression plate is provided on the right outer wall of the base, an auxiliary plate is fixedly connected to the left outer wall of the base, a pushing component is provided inside the auxiliary plate, a motor is provided inside the base, a rotating component is provided on the upper side of the motor, and a cover plate is provided between the two transport shafts.

[0008] Furthermore, the pushing component includes a fixed base fixedly connected inside the auxiliary plate, a gear shaft slidably connected inside the fixed base, and a pushing plate fixedly connected to the right end of the gear shaft.

[0014] This utility model has the following beneficial effects: 1.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figure 1 , Figure 3 and Figure 6 This utility model provides an embodiment of an automatic feeding mechanism for a rack and pinion support, comprising a support feeder 10 and a base 3. The mechanism is characterized by: a transport plate 8 fixedly connected to the left side of the base 3, the transport plate 8 being fixedly connected to the outer wall of the support feeder 10 on the left side; a steering support 9 being provided on the upper side of the support feeder 10; a transport shaft 7 fixedly connected to the front side of the base 3; a fixed shaft 5 being provided at the left end of the transport shaft 7; a sliding cover 28 being slidably connected to the right outer wall of the fixed shaft 5; a hole being provided inside the fixed shaft 5, and a movable ball 12 being provided inside the hole; and a limiting groove being provided on the left outer wall of the transport shaft 7. A cover feeder 6 and a compression plate 1 are connected to the right outer wall of the base 3 via a fixed assembly. An auxiliary plate 11 is fixedly connected to the left outer wall of the base 3, and a fixed seat 16 is provided inside the auxiliary plate 11. A gear shaft 15 is slidably connected inside the fixed seat 16, and a push plate 20 is fixedly connected to the right end of the gear shaft 15. A motor 14 is installed inside the base 3. An arc plate 23 is installed on the upper side of the motor 14. A guide rod 21 is fixedly connected to the outer wall of the arc plate 23. A guide plate 22 is installed on the right side of the arc plate 23. A rotating plate 13 is fixedly connected to the upper end of the guide plate 22. A cover plate 27 is installed between the two transport shafts 7.
[0020] Specifically, the device is mainly used to stack cover plates 27 on the upper side of the steering gear support 9 for compression and fixation. During use, the support plate feeder 10 is used to assist the transport plate 8. The transport plate 8 can keep the steering gear support 9 as only one entry point into the right outer wall of the auxiliary plate 11. By driving the push plate 20, the steering gear support 9 slides to the right and is placed in front of the rotating plate 13 through the rear transverse gripper. The cover plate feeder 6 is used to transport the cover plate 27. Because the cover plate 27 is thin, it can be ensured that only one piece can pass through through the two transport shafts 7. Stacking will cause instability and the cover plate will fall into the cover plate feeder 6 and climb up again. When the cover plate feeder 6 slides to the rear end of the transport shaft 7, the second mechanical claw 4 makes the transport shaft 7 place on the upper side of the steering gear support 9. The rotating plate 13 is rotated, and the first mechanical claw 2 places the whole object inside the compression plate 1 for compression. The starter motor 14 drives the upper arc plate 23 to rotate, which in turn drives the guide plate 22 through the shaft block on the lower side of the guide rod 21, thus rotating the guide plate 22. The guide plate 22 then drives the upper rotating plate 13 to rotate. Because the arc plate 23 and the guide plate 22 are in quarter-part contact, the arc plate 23 rotates one revolution, causing the guide plate 22 to rotate one-quarter of the way. The rotation of the motor 14 drives the first sprocket 24 to rotate, which in turn drives the outer chain 26 to rotate, causing the second sprocket 25 on the left to rotate. The rotation of the second sprocket 25 causes the first transmission gear 17 to rotate, which in turn causes the second transmission gears 18 on both sides to rotate, thus driving the lower residual gear 19 to rotate. Because the residual gear 19 has only a few teeth, only a portion of it can drive the gear shaft 1. 5. Furthermore, the meshing relationship between the second transmission gear 18 and the first transmission gear 17 causes the rotation directions of the second transmission gears 18 on both sides to be opposite. Consequently, the rotation directions of the residual gears 19 on the front and rear sides are opposite. When the teeth of the front residual gear 19 mesh with the gear shaft 15, its rotation can drive the gear shaft 15 to move to the right. At this time, the residual teeth of the rear residual gear 19 do not mesh with the gear shaft 15 and move to the right. When the teeth of the rear residual gear 19 mesh with the gear shaft 15, they will drive the gear shaft 15 to slide to the left. At this time, the residual teeth of the residual gear 19 disengage from the tooth grooves of the gear shaft 15 and will not affect the movement of the gear shaft 15. By repeating this process, the residual gears 19 on both sides can intermittently drive the gear shaft 15 to make reciprocating motion, thereby driving the push plate 20 to push the material. The rotation ratio of the device is that the guide plate 22 rotates twice, and the push plate 20 pushes and returns once. Furthermore, the transport shaft 7 used in the process can be designed with a quick-release design for easy installation. By sliding the sliding cover 28 to the right, the limiting ring on the inner wall of the sliding cover 28 loses its restriction on the movable ball 12, thereby losing its constraint on the transport shaft 7, and can be pulled out for replacement. During installation, the transport shaft 7 is placed inside the fixed shaft 5. By releasing the handle, the sliding cover 28 slides to the left under the action of the spring 29, thereby squeezing the movable ball 12, so that the outer wall of the movable ball 12 is limited inside the limiting groove on the outer wall of the transport shaft 7.
[0021] Reference Figure 2 , Figure 4 and Figure 5 A limiting ring is fixedly connected to the inside of the left side of the sliding cover 28. The outer wall of the limiting ring is located outside the hole. A spring 29 is provided on the inner wall of the sliding cover 28, and the outer wall of the spring 29 is located on the right side of the limiting ring. A first transmission gear 17 is fixedly connected to the rotating end of the motor 14. A second transmission gear 18 is meshed with the outer wall of the first transmission gear 17. A residual gear 19 is fixedly connected to the upper end of the second transmission gear 18, and the outer wall of the residual gear 19 is located on the right side of the gear shaft 15. A first sprocket 24 is fixedly connected to the bottom end of the arc plate 23. A chain 26 is meshed with the outer wall of the first sprocket 24. A second sprocket 25 is meshed with the inner wall of the left side of the chain 26. The outer wall of the second sprocket 25 is fixedly connected to the bottom end of the first transmission gear 17. A first mechanical claw 2 is fixedly connected to the upper outer wall of the base 3. A second mechanical claw 4 is provided on the left side of the first mechanical claw 2, and the outer wall of the second mechanical claw 4 is fixedly connected to the left side of the base 3.
[0022] Specifically, the sliding cover 28 is the core of the quick-release mechanism for the transport shaft 7. Its left-side internally fixed limiting ring fits against the outside of the hole in the fixed shaft 5, restraining the movable ball 12. The spring 29 on the inner wall of the sliding cover 28 abuts against the right side of the limiting ring. When disassembling the shaft, the right sliding cover compresses the spring, causing the limiting ring to disengage from the movable ball 12. After releasing, the spring returns to its original position, pushing the sliding cover to the left and squeezing the movable ball 12 into the limiting groove of the transport shaft 7, achieving quick fixation. In terms of power transmission, the rotating end of the motor 14 is connected to the first transmission gear 17, transmitting torque. The first transmission gear 17 meshes with the second transmission gear 18, achieving power steering and speed adjustment, with the two second transmission gears 18 rotating in opposite directions. The upper end of the second transmission gear 18 is connected to a residual gear 19, correspondingly positioned on the right side of the gear shaft 15. The residual gear 19 has only a portion of its teeth, meshing with the gear shaft 15 at a specific angle. Combined with the opposite rotation on both sides, this enables the gear shaft 15 to intermittently reciprocate, driving the push plate 20 to feed and reset. The bottom end of the arc plate 23 is connected to the first sprocket 24. When the motor 14 drives the arc plate, it synchronously drives the first sprocket. The first sprocket meshes with the chain 26, transmitting power to the second sprocket 25 on the left. The second sprocket is fixed to the bottom end of the first transmission gear 17, so that the motor 14 drives both the arc plate and the first transmission gear 17 simultaneously, ensuring that the rotating plate 13 is positioned and rotated in conjunction with the drive linkage of the gear shaft 15. In terms of gripping and transferring, the first mechanical claw 2 on the upper side of the base 3 grips the steering gear support 9 and the cover plate 27 stacked on the rotating plate 13 and moves them to the compression plate 1 for compression. The second mechanical claw 4 on its left grips the cover plate feeder 6 and sends it to the rear end of the transport shaft 7, accurately placing it on the steering gear support 9 to complete the stacking.
[0023] Working principle: After the motor 14 starts, it drives the upper arc plate 23 to rotate. The guide rod 21 on the outer wall of the arc plate 23 is embedded in the limiting groove inside the guide plate 22 through the lower shaft block, thereby driving the guide plate 22 to rotate. Since the arc plate 23 only contacts a quarter of the area of the guide plate 22, when the arc plate 23 rotates one revolution, the guide plate 22 only rotates a quarter revolution. The guide plate 22 is fixedly connected to the upper rotating plate 13, which ultimately drives the rotating plate 13 to achieve precise angle rotation. At the same time, the rotation of the motor 14 will also drive the first sprocket 24 to rotate synchronously. The first sprocket 24 is driven by the outer chain 26, which causes the second sprocket 25 on the left to rotate accordingly. The second sprocket 25 is fixedly connected to the first transmission gear 17, which in turn drives the first transmission gear 17 to rotate. The first transmission gear 17 meshes with the second transmission gears 18 on both sides. Due to the meshing relationship, the second transmission gears 18 on both sides rotate in opposite directions. Each second transmission gear 18 is fixed to the lower residual gear 19, so the front and rear residual gears 19 also rotate in opposite directions. Since the residual gear 19 only has a portion of its teeth, it meshes with the gear shaft 15 only at specific positions: when the front residual gear 19 meshes with the gear shaft 15, it drives the gear shaft 15 to move to the right. At this time, the residual teeth of the rear residual gear 19 do not contact the gear shaft 15 and do not interfere. When the rear residual gear 19 meshes with the gear shaft 15, it drives the gear shaft 15 to slide to the left. At this time, the residual teeth of the front residual gear 19 disengage from the tooth groove of the gear shaft 15, which also does not affect the movement. This process repeats, with the two residual gears 19 intermittently driving the gear shaft 15 to make reciprocating motion. The push plate 20 at the right end of the gear shaft 15 moves synchronously, realizing material pushing and resetting.
[0024] On the other hand, the transport shaft 7 adopts a quick-release design, which facilitates later maintenance: when disassembling, slide the sliding cover 28 on the outer wall of the fixed shaft 5 to the right, and the inner wall limiting ring of the sliding cover 28 moves accordingly, losing the squeezing restriction on the movable ball 12 inside the fixed shaft 5. The movable ball 12 disengages from the limiting groove on the outer wall of the transport shaft 7, and the transport shaft 7 can be directly pulled out for replacement; when installing, put the transport shaft 7 into the fixed shaft 5, loosen the sliding cover 28, and the sliding cover 28 returns to the left under the elastic force of the internal spring 29, squeezing the movable ball 12 again, so that the movable ball 12 is inserted into the limiting groove on the outer wall of the transport shaft 7, thus completing the quick fixation of the transport shaft 7.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
