Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-10 This utility model provides a technical solution:

[0031] Overall Architecture: This intelligent automated storage and retrieval mechanism for bus bearings includes a power distribution cabinet 4. The power distribution cabinet 4 serves as the power hub of the entire system, providing a stable and reliable power supply to other components to ensure the normal operation of the mechanism. A Z-direction guide structure 2 is installed on the side of the power distribution cabinet 4. A Y-direction three-stage telescopic fork structure 1 is slidably installed on the side of the Z-direction guide structure 2. An X-direction guide structure 3 is installed at the bottom of the Z-direction guide structure 2. These three structures cooperate with each other, enabling the storage and retrieval mechanism to move freely in three-dimensional space and achieve precise storage and retrieval of bus bearings.

[0032] Y-axis three-stage telescopic fork structure: The Y-axis three-stage telescopic fork structure 1 is a key component for picking up and storing goods. It includes rotationally symmetrically distributed Y-axis forks 17 and 18. Taking Y-axis fork 17 as an example, it consists of an upper sliding seat 171, a middle sliding seat 172, and a bottom seat 176. The bottom seat 176 is stably connected to the base 175 through a bottom mounting seat 178. Rollers are used to connect the upper sliding seat 171 to the middle sliding seat 172 and the middle sliding seat 172 to the bottom seat 176. This connection method can ensure smooth sliding between the sliding seats and effectively reduce frictional resistance and improve the response speed of telescopic action.

[0033] The Y-axis motor 174 mounted on the side of the base 175 is the power source of the Y-axis three-stage telescopic fork structure 1. The middle sliding seat 172 is equipped with a Y-axis rack 1715. The Y-axis gear 173 mounted on the output shaft of the Y-axis motor 174 meshes with the Y-axis rack 1715. When the Y-axis motor 174 is started, the Y-axis gear 173 rotates, driving the Y-axis rack 1715 to move, thereby realizing the sliding of the middle sliding seat 172 relative to the bottom seat 176.

[0034] Chain adjustment seats 177 are installed on the surfaces of the bases 175 on both sides of the bottom seat 176. A Y-direction chain 1713 is connected between the fixing plate 1712 installed at the bottom of the upper sliding seat 171 and the chain adjustment seat 177. The support sprocket 1714 set on the side of the middle sliding seat 172 supports and guides the Y-direction chain 1713. When the middle sliding seat 172 slides, the upper sliding seat 171 slides relative to the middle sliding seat 172 through the Y-direction chain 1713, thereby realizing the three-stage telescopic function of the Y-direction fork. Through this combination of gear rack and chain drive, the Y-direction three-stage telescopic fork structure 1 can achieve a larger stroke range, which can flexibly adapt to the needs of goods storage and retrieval in racks of different depths. At the same time, it also has a high load capacity, ensuring stable operation when handling heavy passenger car bearings.

[0035] In addition, the Y-axis three-stage telescopic fork structure 1 also includes a fork base 11. A photoelectric switch mounting base 15 is installed on the surface of the fork base 11 of the Y-axis fork one 17 and the Y-axis fork two 18. A high-precision photoelectric sensor is equipped on the photoelectric switch bracket 16 installed on the side of the photoelectric switch mounting base 15. A U-shaped mounting bracket 12 is installed on the surface of the fork base 11 corresponding to the Z-axis column 21. The Z-axis guide wheel 13 and Z-axis guide wheel 14 are set inside the U-shaped mounting bracket 12, so that the Y-axis three-stage telescopic fork structure 1 can slide smoothly along the Z-axis guide structure 2. A proximity switch 179 is installed on the surface of the photoelectric switch mounting base 15 corresponding to the bottom mounting base 178, which can accurately detect the telescopic position of the fork. A tooling plate 1711 is installed on the surface of the upper sliding seat 171, which is specifically used to place the bus bearing. The design of the tooling plate 1711 fully considers the shape and size characteristics of the bus bearing, which can ensure that the bearing remains stable during transportation and avoid displacement and damage.

[0036] Z-direction guide structure: The Z-direction guide structure 2 is mainly composed of a column 21. Guide steel strips 22 are installed on the side of the column 21 at the positions of the Z-direction guide wheel 13 and Z-direction guide wheel 14 inside the U-shaped mounting frame 12. The guide steel strips 22 provide a precise guide track for the Z-direction guide wheel 13 and Z-direction guide wheel 14, effectively reducing the swaying of the Y-direction three-stage telescopic fork structure 1 during the lifting process, and improving the stability and positioning accuracy of the lifting.

[0037] A Z-axis motor 24 is mounted on the top of the column 21 via a motor tensioning plate 23. Two drive shafts 25 are installed inside the top of the column 21. One drive shaft 25 is connected to the output shaft of the Z-axis motor 24 via a chain drive structure 27. When the Z-axis motor 24 starts, power is transmitted to the drive shaft 25 via the chain drive structure 27, causing the drive shaft 25 to rotate. Both ends of the drive shaft 25 extend outside the column 21 and are connected to lifting sprockets 28. A lifting chain 29 connected to the lifting sprocket 28 has one end connected to a U-shaped mounting bracket 12 via a chain connecting screw 210, and the other end connected to a counterweight chain connecting plate 212. The counterweight 211 installed inside the counterweight chain connecting plate 212 balances the weight of the Y-axis three-stage telescopic fork structure 1 during lifting, effectively reducing the load on the Z-axis motor 24, reducing energy consumption, and improving the stability of the lifting process. A Z-axis motor 24 is mounted on the side of the Z-axis column 21. The column slide rail 213 provides a stable sliding guide for the counterweight chain connecting plate 212, ensuring that the counterweight 211 remains stable during the lifting process and does not deviate or jam.

[0038] X-direction guide structure: The X-direction guide structure 3 includes a steel rail 31 set below the Z-direction column 21, a rack 32 installed on the side of the steel rail 31, and an X-direction column base 33 installed at the bottom of the Z-direction column 21, which is a key component connecting the Z-direction guide structure 2 and the X-direction guide structure 3. An X-direction motor 39 installed on the side of the X-direction column base 33 serves as the power source for X-direction movement, providing driving force for the horizontal movement of the entire mechanism.

[0039] X-axis gear 1 310 and X-axis gear 2 311, which are mounted on the output shaft of X-axis motor 39, mesh with each other. X-axis gear 2 311 is mounted inside X-axis column base 33 through a rotating shaft, and X-axis gear 2 311 cooperates with X-axis rack 32. When X-axis motor 39 is started, X-axis gear 1 310 rotates, which drives X-axis gear 2 311 to rotate, thereby causing X-axis column base 33 to move along rail 31, realizing the precise movement of the entire storage and retrieval mechanism in the X-axis direction.

[0040] X-direction driven wheel seats 34 are installed at both ends of the X-direction column base 33. X-direction driven wheels 35 installed inside the X-direction driven wheel seats 34 can roll on the surface of the rail 31, providing support and guidance for the movement of the mechanism, reducing frictional resistance during movement, and improving operating efficiency. X-direction limiting blocks 312 installed at both ends of the rail 31, and X-direction limiting blocks 313 installed on the X-direction driven wheel seats 34 corresponding to the X-direction limiting blocks 312, together constitute a limiting device for X-direction movement, effectively preventing the mechanism from overtravel and ensuring the safety of equipment and goods. X-direction buffers 36 are installed at the positions of the X-direction driven wheel seats 34 corresponding to the X-direction limiting blocks 313, which can buffer when the mechanism reaches its limit position, reducing collision impact and further protecting the equipment. X-direction buffers 36 are installed on both sides of the X-direction driven wheel seats 34 below the X-direction buffers 36. The guide wheel 37 is tangentially set to the side of the rail 31, which can further improve the stability of the mechanism in the horizontal direction and prevent the mechanism from deviating and shaking. The rail 31 is firmly fixed to the ground by the rail pad 314 and chemical bolts 315, ensuring the stability and reliability of the entire X-direction guide structure.

[0041] In addition, the X-axis upward guide angle steel 316 installed above the Z-axis guide structure 2 is suspended on the roof. The X-axis upward guide wheel mounting seat 317 is installed at the top of the Z-axis guide structure 2 corresponding to the position of the guide angle steel 316, and the X-axis upward guide wheels 318 are installed at the top of the X-axis upward guide wheel mounting seats 317 on both sides of the X-axis upward guide angle steel 316. The X-axis upward guide wheels 318 are tangentially set to the side of the X-axis upward guide angle steel 316. This structure further enhances the stability of the mechanism in the X-axis direction. Especially under high-speed movement and heavy load, it can effectively suppress the vibration and shaking of the mechanism and ensure the accuracy of storage and retrieval operations.

[0042] Overall structure of the organization

[0043] The intelligent automated storage and retrieval mechanism for passenger vehicle bearings of this invention mainly consists of a power distribution cabinet 4, a Z-direction guide structure 2, a Y-direction three-stage telescopic fork structure 1, and an X-direction guide structure 3. The power distribution cabinet 4 provides power support for the entire mechanism. The Z-direction guide structure 2 is installed on the side of the power distribution cabinet 4 to realize the lifting and lowering movement of the Y-direction three-stage telescopic fork structure 1. The X-direction guide structure 3 is installed at the bottom of the Z-direction guide structure 2 to realize the horizontal movement of the entire mechanism.

[0044] Working principle of Y-axis three-stage telescopic fork structure

[0045] The Y-direction three-stage telescopic fork structure 1 includes a Y-direction fork one 17 and a Y-direction fork two 18, which are rotationally symmetrically distributed. When goods need to be stored or retrieved, the Y-direction motor 174 is started, driving the Y-direction gear 173 to rotate. The Y-direction gear 173 cooperates with the Y-direction rack 1715 to drive the middle sliding seat 172 to slide relative to the bottom seat 176. At the same time, the sliding of the middle sliding seat 172 drives the upper sliding seat 171 to slide relative to the middle sliding seat 172 through the Y-direction chain 1713, thereby realizing the three-stage telescopic extension of the forks. The support sprocket 1714 supports the Y-direction chain 1713 to ensure the stability of the chain drive.

[0046] The tooling plate 1711 is used to place the bus bearing. The photoelectric switch and proximity switch 179 installed on the photoelectric switch mounting base 15 and photoelectric switch bracket 16 are used to detect the position and status of the goods and realize automated control.

[0047] Z-direction guide structure working principle

[0048] After the Z-axis motor 24 starts, it drives the drive shaft 25 to rotate through the chain transmission structure 27. The lifting sprockets 28 at both ends of the drive shaft 25 rotate accordingly, driving the lifting chain 29 to move. One end of the lifting chain 29 is connected to the U-shaped mounting bracket 12, and the other end is connected to the counterweight chain connecting plate 212, thereby realizing the lifting movement of the Y-axis three-stage telescopic fork structure 1. The counterweight 211 balances the load and reduces motor energy consumption.

[0049] Z-axis guide wheels 13 and 14 roll on guide steel bars 22, ensuring stability and accuracy during the lifting process. Z-axis column slide rail 213 provides sliding guidance for counterweight chain connecting plate 212.

[0050] X-direction guide structure working principle

[0051] After the X-axis motor 39 is started, it drives the X-axis gear 310 to rotate. The X-axis gear 310 meshes with the X-axis gear 311, and the X-axis gear 311 cooperates with the X-axis rack 32, driving the entire mechanism to move on the rail 31. The X-axis driven wheel 35 rolls on the surface of the rail 31, reducing frictional resistance.

[0052] The X-direction guide wheel 37 is tangent to the side of the rail 31, ensuring the stability of the mechanism in the horizontal direction. The X-direction limit block 313 and the X-direction buffer 36 prevent the mechanism from overtraveling and protect the equipment. The X-direction upward guide wheel 318 cooperates with the X-direction upward guide angle steel 316 suspended on the roof to further improve the stability of the mechanism.

[0053] Access Workflow

[0054] When it is necessary to access the bus bearing, the control system first moves the mechanism to the X-axis coordinate of the target position through the X-direction guide structure 3 according to the instruction. Then, it adjusts the Y-direction three-stage telescopic fork structure 1 to the Z-axis coordinate of the target position through the Z-direction guide structure 2. Finally, the access operation of the bearing is realized by the extension and retraction of the Y-direction three-stage telescopic fork structure 1. The whole process is precisely controlled by a dual servo system, ensuring the efficiency and accuracy of access.
