Description

Technical Field

[0001] The present application relates to the technical field of omnidirectional wheels, and in particular to a wheel for AGV and a production process thereof. Background Art

[0002] The omnidirectional wheel is a special wheel design. The structural feature of the omnidirectional wheel is that the hub axis and the roller axis are perpendicular to each other, so that the wheel can move forward or backward along the direction of the hub rotation, and can also move sideways. This design makes the omnidirectional wheel highly maneuverable in space-constrained environments, such as small warehouses. When the omnidirectional wheel is used in an AGV, the AGV can move forward, backward, and sideways, which can improve the flexibility of the AGV in the automated logistics system.

[0003] At present, the existing omnidirectional wheels mainly include a wheel hub, a plurality of brackets and a plurality of wheels. The wheels and the brackets are arranged one by one, the wheels are rotatably connected to the corresponding brackets, the plurality of brackets are arranged in sequence along the circumference of the wheel hub, and the brackets and the wheel hub adopt a steel plate welding structure. Since the brackets and the wheel hub are connected by welding, during the process of assembling the omnidirectional wheel, the plurality of brackets need to be welded to the wheel hub in sequence along the circumference of the wheel hub. Since the wheels on the circumference of the wheel hub are arranged densely, the number of wheels installed on the wheel hub is relatively large, which leads to a large number of brackets, which requires a long welding time. Therefore, the welding connection method makes the assembly process of the omnidirectional wheel more complicated, which in turn leads to a low production efficiency of the omnidirectional wheel. Summary of the invention

[0004] The present application provides a wheel for AGV and a production process thereof, the purpose of which is to reduce the assembly complexity of the wheel for AGV, thereby reducing the assembly difficulty of the wheel for AGV and improving the production efficiency of the wheel for AGV.

[0005] In the first aspect, the present application provides an AGV wheel adopting the following technical solution: A wheel for an AGV comprises a first half wheel and a second half wheel, wherein a plurality of first support wheels are arranged on the circumference of the first half wheel, and the axial directions of the plurality of first support wheels are arranged perpendicularly to the axial directions of the first half wheel; a plurality of second support wheels are arranged on the circumference of the second half wheel, and the axial directions of the plurality of second support wheels are arranged perpendicularly to the axial directions of the second half wheel; the first half wheel and the second half wheel are coaxially detachably connected, and the first support wheels and the second support wheels are arranged in a circular ring and arranged around the central axis of the first half wheel.

[0006] By adopting the above technical solution, firstly, the first half wheel and the second half wheel can be coaxially spliced ​​to form a complete wheel, which meets the basic functions of the AGV wheel and enables the AGV trolley to move forward and backward.

[0007] Secondly, since a plurality of first support wheels are arranged on the outside of the first half wheel and a plurality of second support wheels are arranged on the outside of the second half wheel, after the first half wheel and the second half wheel are coaxially assembled, the plurality of first support wheels and the second support wheels are ring-shaped and surround the outside of the first half wheel and the second half wheel, and since the axes of the first support wheels and the second support wheels are perpendicular to the axis of the first half wheel, when the AGV trolley moves laterally, the first support wheel and / or the second support wheel corresponding to the contact with the ground can roll with the ground, thereby satisfying the function of lateral movement of the AGV wheels.

[0008] Through such a structural arrangement, when it is necessary to produce wheels for AGV, the first half wheel and the second half wheel can be produced at the same time, and the first support wheel and the second support wheel can be assembled at the same time. Furthermore, when it is necessary to assemble the wheels for AGV, it is only necessary to coaxially splice and fix the first half wheel and the second half wheel, which can reduce the assembly complexity of the wheels for AGV, thereby reducing the assembly difficulty of the wheels for AGV and improving the production efficiency of the wheels for AGV.

[0009] Optionally, the first support wheel includes a first hub plate, a plurality of first brackets are arranged on the first hub plate, the first brackets are arranged in a one-to-one correspondence with the first support wheel, and the first brackets are rotatably connected to the corresponding first support wheel; the second support wheel includes a second hub plate, a plurality of second brackets are arranged on the second hub plate, the second brackets are arranged in a one-to-one correspondence with the second support wheel, and the second brackets are rotatably connected to the second support wheel; the first hub plate and the second hub plate are coaxially spaced, the first bracket and the second bracket are both located between the first hub plate and the second hub plate, the first bracket is detachably connected to the second hub plate, and the second bracket is detachably connected to the first hub plate.

[0010] By adopting the above technical solution, the first bracket is provided to realize the installation of the first support wheel. The second bracket is provided to realize the installation of the second support wheel. The first bracket and the second bracket are both located between the first hub plate and the second hub plate, and the first bracket is detachably connected to the second hub plate, and the second bracket is detachably connected to the first hub plate, so the first bracket and the second bracket can support the first hub plate and the second hub plate, thereby improving the structural strength of the entire AGV wheel.

[0011] Optionally, the first bracket and the second bracket are alternately arranged in sequence along the circumference of the first hub plate.

[0012] By adopting the above technical solution, since the first bracket and the second bracket are alternately arranged along the circumference of the first hub plate, the first hub plate and the second hub plate are subjected to uniform force at various locations along their own circumference, thereby improving the structural strength of the entire AGV wheel.

[0013] Optionally, the first bracket is integrally formed with the first hub plate, and the second bracket is integrally formed with the second hub plate.

[0014] By adopting the above technical solution, since the first bracket and the first hub plate are integrally formed, and the second bracket and the second hub plate are integrally formed, such a configuration can, on the one hand, reduce the number of parts of the AGV wheel and facilitate the assembly of the AGV wheel; on the other hand, it can improve the connection strength between the first hub plate and the first bracket and between the second hub plate and the second bracket, thereby improving the strength of the entire AGV wheel.

[0015] Optionally, the first bracket includes a first connecting plate, which is perpendicular to the first hub plate, and one side of the first connecting plate in the width direction is connected to the first hub plate, and the other side is in contact with the second hub plate; one end of the first connecting plate along its own length direction is located between the first hub plate and the second hub plate, and the other end is extended in the direction away from the first hub plate, and the first support wheel is rotatably connected to the first connecting plate.

[0016] By adopting the above technical solution, one side of the first connecting plate is connected to the first hub plate, and the other side is in contact with the second hub plate, so that the function of the first bracket can be realized. On this basis, since one end of the first connecting plate extends out of the spacing between the first hub plate and the second hub plate, it is ensured that the first support wheel can be installed to the outside of the spacing between the first hub plate and the second hub plate, meeting the installation requirements of the first support wheel.

[0017] Optionally, the first bracket also includes a first fixing plate, which is arranged parallel to the first hub plate; the first connecting plate is connected to the first fixing plate on the side facing away from the first hub plate, the first fixing plate is in contact with the second hub plate, and the first fixing plate and the second hub plate are detachably connected.

[0018] By adopting the above technical solution, the provision of the first fixing plate can increase the contact area between the first connecting plate and the second hub plate, thereby improving the force uniformity of the second hub plate and improving the installation stability of the first fixing plate and the second hub plate.

[0019] Optionally, a first give-way plate is arranged between the first connecting plate and the first hub plate, the first give-way plate is flush with the first hub plate, one end of the first give-way plate in the length direction is connected to the first connecting plate, and the other end is connected to the first hub plate, and the first give-way plate is used to bend itself and drive the corresponding first connecting plate to give way.

[0020] By adopting the above technical solution, the first give-way plate is provided to connect the first hub plate and the first connecting plate. Since the first give-way plate can bend itself, it is convenient to bend the first give-way plate, so that the first connecting plate is displaced, and then the corresponding first support wheel is displaced.

[0021] During the assembly process of the first half wheel and the second half wheel, when the number of the first support wheels and the second support wheels is large, there is interference between the first support wheel and another adjacent second support wheel. At this time, a first clearance plate is bent to move the corresponding first support wheel away, so that several first support wheels and several second support wheels can be smoothly assembled together, and then the corresponding first clearance plate is reset. At this time, the first half wheel and the second half wheel can be smoothly fixed, which facilitates the assembly of the wheels for AGV.

[0022] Optionally, the first clearance plate is spaced apart from the first hub plate along its width direction toward one side of the first hub plate and forms a deformation groove; a deformation hole is provided at the connection between the first clearance plate and the first hub plate, and the deformation groove is connected to the deformation hole.

[0023] By adopting the above technical solution, the structural arrangement of the deformation groove and the deformation hole can reduce the strength of the connection structure between the first clearance plate and the first hub plate, thereby facilitating the bending and deformation of the first clearance plate.

[0024] In the second aspect, the present application provides a production process for AGV wheels using the following technical solutions: A production process for AGV wheels, used for the production of the above-mentioned AGV wheels, includes the following steps: S1, making a first half wheel and a second half wheel: processing a plurality of first brackets on a first wheel hub plate, and processing a plurality of second brackets on a second wheel hub plate; S2, installing a first support wheel on the first bracket, and installing a second support wheel on the second bracket; S3, coaxially splicing the first half wheel and the second half wheel, and fixing the first half wheel and the second half wheel.

[0025] By adopting the above technical solution, the assembly of AGV wheels can be realized. Since the first half wheel and the second half wheel can be processed at the same time, the first support wheel on the first half wheel and the second support wheel on the second half wheel can be installed at the same time, which can reduce the processing time of various components of the AGV wheel; and when assembling the AGV wheels, it is only necessary to coaxially splice the processed first half wheel and the second half wheel, which can greatly reduce the requirements and difficulty of assembling the AGV wheels.

[0026] Optionally, the step of processing a plurality of first brackets on the first hub plate in step S1 further includes the following steps: S11, processing a plurality of holes on the first hub plate; S12, cutting a plurality of first clearance plates, a plurality of first connecting plates and a plurality of first fixed plates on the first hub plate by laser cutting or wire cutting; S13, bending a plurality of first fixed plates and a plurality of first connecting plates in sequence by bending processing, and making the first fixed plates parallel to the first hub plate, and the first connecting plates perpendicular to the first hub plate.

[0027] By adopting the above technical solution, laser cutting or wire cutting combined with bending technology, a plurality of first brackets can be processed on the first hub plate, and the first brackets and the first hub plate are formed integrally, which can reduce the number of parts of the first half wheel, reduce the assembly complexity of the first half wheel, and thus reduce the assembly complexity of the entire AGV wheel set, thereby reducing the assembly difficulty of the AGV wheels and improving the production efficiency of the AGV wheels.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application can realize the assembly of the AGV wheels by coaxially engaging the first half wheel with the second half wheel, which can reduce the assembly complexity of the entire AGV wheel set, thereby reducing the assembly difficulty of the AGV wheels and improving the production efficiency of the AGV wheels.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 -Attached Fig. 9 , further details of this application are given.

[0042] Embodiment 1: A wheel for AGV, referring to Figure 1 , including a first half wheel 1, a second half wheel 2 and a plurality of support wheel groups 3, the support wheel group 3 including a first support wheel 31 and a second support wheel 32, the plurality of first support wheels 31 are arranged around the first half wheel 1 along the circumference of the first half wheel 1, the axial direction of the first support wheel 31 is perpendicular to the axial direction of the first half wheel 1, the plurality of second support wheels 32 are arranged around the second half wheel 2 along the circumference of the second half wheel 2, the axial direction of the second support wheel 32 is perpendicular to the axial direction of the second half wheel 2. The first half wheel 1 is coaxially buckled with the second half wheel 2, and the first half wheel 1 and the second half wheel 2 are detachably connected, the plurality of first support wheels 31 and the plurality of second support wheels 32 are arranged in a circle, and the first half wheel 1 and the second half wheel 2 are arranged around the central axis of the first half wheel 1, and the first support wheels 31 and the second support wheels 32 are alternately arranged in sequence along the circumference of the first half wheel 1.

[0043] After the first half wheel 1 and the second half wheel 2 are coaxially connected, they can form a wheel shape, thereby meeting the requirements of AGV wheels.

[0044] In this embodiment, refer to Figure 1 , the diameter of the first support wheel 31 is smaller than the diameter of the second support wheel 32. By setting the first support wheel 31 and the second support wheel 32 of different sizes, the gap between two adjacent second support wheels 32 can be reduced, so that the outer contour of the AGV wheel is closer to a circle, so that when the AGV is used to move forward or backward, the movement of the AGV is more stable.

[0045] Reference Figure 1 and Figure 2 The first half wheel 1 includes a first hub plate 11 and a plurality of first brackets 12, which are arranged in sequence along the circumference of the first hub plate 11, and one end of the first bracket 12 is connected to the first hub plate 11. The first brackets 12 are arranged in one-to-one correspondence with the first support wheels 31, and the first brackets 12 are rotatably connected to the corresponding first support wheels 31.

[0046] Reference Figure 1 The second half wheel 2 includes a second hub plate 21 and a plurality of second brackets 22, which are arranged in sequence along the circumference of the second hub plate 21, and one end of the second bracket 22 is connected to the second hub plate 21. The second brackets 22 are arranged in a one-to-one correspondence with the second support wheels 32, and the second brackets 22 are rotatably connected to the corresponding second support wheels 32.

[0047] Reference Figure 1 , the first hub plate 11 and the second hub plate 21 are coaxially arranged, and the first hub plate 11 is spaced apart from the second hub plate 21 along its own axial direction. The first bracket 12 and the second bracket 22 are both located between the first hub plate 11 and the second hub plate 21, and the side of the first bracket 12 away from the first hub plate 11 abuts against the second hub plate 21. Similarly, the side of the second bracket 22 away from the second hub plate 21 abuts against the first hub plate 11, and a plurality of first brackets 12 and a plurality of second brackets 22 are alternately arranged in sequence along the circumference of the first hub plate 11. After the first half wheel 1 and the second half wheel 2 are coaxially buckled, the first bracket 12 and the second bracket 22 can support the first hub plate 11 and the second hub plate 21, thereby improving the stability and structural strength of the first half wheel 1 and the second half wheel 2 after being connected.

[0048] Reference Figure 2 and Figure 3The first bracket 12 includes a first give-way plate 121, a first connecting plate 122 and a first fixing plate 123. The first give-way plate 121 is flush with the first hub plate 11. The first connecting plate 122 is vertically arranged with the first give-way plate 121. The first fixing plate 123 is parallel to the first hub plate 11. The first connecting plate 122 is located between the first hub plate 11 and the first fixing plate 123 along the axial direction of the first hub plate 11, and the first hub plate 11, the first give-way plate 121, the first connecting plate 122 and the first fixing plate 123 are connected in sequence.

[0049] In this embodiment, refer to Figure 3 and Figure 4 The first bracket 12 has the same structure as the second bracket 22. The second bracket 22 includes a second give-way plate 221, a second connecting plate 222 and a second fixing plate 223. The first hub plate 11 has the same structure as the second hub plate 21, the first give-way plate 121 has the same structure as the second give-way plate 221, the first connecting plate 122 has the same structure as the second connecting plate 222, and the first fixing plate 123 has the same structure as the second fixing plate 223.

[0050] Reference Figure 1 and Figure 4 When the first half wheel 1 and the second half wheel 2 are coaxially buckled, the side of the first fixing plate 123 facing away from the first hub plate 11 abuts against the second hub plate 21, and the side of the second fixing plate 223 facing away from the second hub plate 21 abuts against the first hub plate 11. Such a structural arrangement enables the first bracket 12 and the second bracket 22 to support the first hub plate 11 and the second hub plate 21.

[0051] Reference Figure 3 The first clearance plate 121 is arc-shaped along its length direction, one end of the first clearance plate 121 in the length direction is connected to the first hub plate 11, and the other end is fixedly connected to the first connecting plate 122. The first clearance plate 121 is spaced from the side wall of the first hub plate 11 along its width direction toward the first hub plate 11, and the space between the first clearance plate 121 and the first hub plate 11 in the width direction forms a deformation groove 1211.

[0052] Reference Figure 2 and Figure 3 Since one end of the first give way plate 121 in the length direction is connected to the first hub plate 11, the deformation groove 1211 is formed between the first give way plate 121 and the first hub plate 11, which limits the length of the connection between the first give way plate 121 and the first hub plate 11. This makes it easy for the staff to bend the first give way plate 121 with force, so as to fine-tune the position of the corresponding first bracket 12, and then achieve fine-tuning of the position of the corresponding first support wheel 31.

[0053] Reference Figure 1 river Figure 3During the assembly process of the first half wheel 1 and the second half wheel 2, when the number of the first support wheels 31 and the second support wheels 32 is large, there is interference between the first support wheel 31 and another adjacent second support wheel 32. At this time, by bending a first clearance plate 121, the corresponding first support wheel 31 is moved away, which makes it possible to smoothly assemble a plurality of first support wheels 31 and a plurality of second support wheels 32 together, and then reset the corresponding first clearance plate 121. At this time, the first half wheel 1 and the second half wheel 2 can be fixed, which facilitates the assembly of the wheels for AGV.

[0054] Reference Figure 3 The first hub plate 11 is also provided with a deformation hole 1212, and one side of the deformation groove 1211 along its length direction is connected to the deformation hole 1212. The provision of the deformation hole 1212 reduces the strength of the connection between the first clearance plate 121 and the first hub plate 11, making the first clearance plate 121 easier to bend and deform.

[0055] Reference Figure 3 and Figure 4 After the first half wheel 1 and the second half wheel 2 are coaxially installed, the first clearance plate 121 and the second fixing plate 223 are arranged in one-to-one correspondence, and the side of the second fixing plate 223 away from the second hub plate 21 simultaneously contacts the first hub plate 11 and the corresponding first clearance plate 121. The first clearance plate 121 is provided with a first reinforcement hole 1213, and the second fixing plate 223 is provided with a second reinforcement hole 2231, and the first reinforcement hole 1213 is coaxially connected with the corresponding second reinforcement hole 2231.

[0056] Reference Figure 1 and Figure 4 A reinforcing bolt 4 is inserted into the first reinforcing hole 1213, and the reinforcing bolt 4 is coaxially inserted and matched with the corresponding second reinforcing hole 2231. Through the cooperation of the first reinforcing hole 1213, the second reinforcing hole 2231 and the reinforcing bolt 4, the first clearance plate 121 can be connected to the corresponding second fixing plate 223, which can improve the stability of the first clearance plate 121 and reduce the possibility of deformation of the first clearance plate 121 during use.

[0057] Similarly, refer to Figure 3 and Figure 4 The second giving way plate 221 and the first fixing plate 123 are arranged in a one-to-one correspondence, and the first reinforcement hole 1213 on the second giving way plate 221 and the corresponding second reinforcement hole 2231 on the first fixing plate 123 are arranged coaxially.

[0058] Reference Figure 1 and Figure 4The second clearance plate 221 and the corresponding first fixing plate 123 can also be installed through the cooperation of the first reinforcement hole 1213, the second reinforcement hole 2231 and the reinforcement bolt 4, which can further increase the stability of the first half wheel 1 and the second half wheel 2 after assembly.

[0059] Reference Figure 3 and Figure 4 The first connecting plate 122 is arranged along the axial direction of the first hub plate 11 in the width direction, and one side of the first connecting plate 122 in the width direction is fixedly connected to the first giving way plate 121, and the other side in the width direction is connected to the first fixing plate 123. One end of the first connecting plate 122 in the length direction is located between the first hub plate 11 and the second hub plate 21, and the other end is extended in the direction away from the first hub plate 11.

[0060] Reference Figure 2 and Figure 3 The first connecting plate 122 is provided with a connecting hole 1221, into which the connecting shaft 5 is inserted, and along the axial direction of the connecting shaft 5, the first connecting plate 122 is located in the middle of the connecting shaft 5, and the first supporting wheel 31 is coaxially rotatably connected with the connecting shaft 5. The opening of the connecting hole 1221 on the first connecting plate 122 realizes the installation of the connecting shaft 5, and thus facilitates the installation of the first supporting wheel 31.

[0061] Similarly, refer to Figure 1 and Figure 2 The corresponding connecting shaft 5 is also inserted into the connecting hole 1221 on the second connecting plate 222, and the connecting shaft 5 on the second connecting plate 222 is rotatably connected to the second supporting wheel 32, so the connecting shaft 5 on the second connecting plate 222 facilitates the installation of the second supporting wheel 32. In this embodiment, refer to Figure 1 and Figure 2 After the connecting shaft 5 is installed with the corresponding first connecting plate 122 or the second connecting plate 222, the connecting shaft 5 is welded with the corresponding first connecting plate 122 or the second connecting plate 222, which can improve the installation stability of the connecting shaft 5.

[0062] In this embodiment, refer to Figure 1 and Figure 2 Since the diameters of the first support wheel 31 and the second support wheel 32 are different, in order to ensure that the outer side walls of the first support wheel 31 and the second support wheel 32 can contact the ground during the use of the AGV wheels, the position of the connecting hole 1221 on the first connecting plate 122 and the position of the connecting hole 1221 on the second connecting plate 222 will be adjusted according to actual requirements.

[0063] Reference Figure 3 and Figure 4A first fixing hole 1231 is formed through the first fixing plate 123, and a plurality of second fixing holes 211 are formed on the second hub plate 21. The first fixing holes 1231 correspond to the second fixing holes 211 one by one, and the first fixing holes 1231 are coaxially connected with the corresponding second fixing holes 211.

[0064] Reference Figure 1 and Figure 4 The second fixing hole 211 is inserted with a fixing bolt 6, and the fixing bolt 6 is coaxially plugged with the corresponding first fixing hole 1231. The first fixing plate 123 and the second hub plate 21 are installed and fixed by the fixing bolt 6, so that the first half wheel 1 and the second half wheel 2 can be installed.

[0065] Similarly, refer to Figure 1 and Figure 4 The first fixing holes 1231 on the second fixing plate 223 and the second fixing holes 211 on the second wheel hub plate 21 are arranged in a one-to-one correspondence, and the first fixing holes 1231 on the second fixing plate 223 are coaxially connected with the corresponding second fixing holes 211 on the first wheel hub plate 11. Therefore, the second fixing plate 223 and the first wheel hub plate 11 can also be installed through the corresponding first fixing holes 1231, the second fixing holes 211 and the fixing bolts 6, thereby improving the stability of the first half wheel 1 and the second half wheel 2 after assembly.

[0066] In this embodiment, refer to Figure 3 and Figure 5 , the first hub plate 11, the first give way plate 121, the first connecting plate 122 and the first fixing plate 123 are integrally formed. Specifically, the contours of the first give way plate 121, the first connecting plate 122 and the first fixing plate 123 are cut out on the first hub plate 11 by laser cutting or wire cutting, and then a plurality of first fixing plates 123 and a plurality of first connecting plates 122 are bent by bending processing, so that a plurality of first brackets 12 can be processed on the first hub plate 11. Similarly, the second bracket 22 can be processed on the second hub plate 21. Such a processing method, on the one hand, can reduce the number of parts of the AGV wheel and facilitate the assembly of the AGV wheel; on the other hand, it can improve the connection strength between the first hub plate 11 and the first bracket 12 and between the second hub plate 21 and the second bracket 22, so as to improve the strength of the entire AGV wheel.

[0067] The implementation principle of the embodiment of the present application is: by simultaneously processing and producing the first half wheel 1 and the second half wheel 2, and then simultaneously installing a plurality of first support wheels 31 on the first half wheel 1 and installing the second support wheel 32 on the second half wheel 2, thereafter coaxially buckling the first half wheel 1 and the second half wheel 2, fine-tuning the positions of the first half wheel 1 and the second half wheel 2, and installing all the reinforcing bolts 4 and fixing bolts 6 in sequence to achieve the installation of the first half wheel 1 and the second half wheel 2.

[0068] Since welding is not required when assembling the AGV wheels, it is only necessary to buckle the first half wheel 1 and the second half wheel 2 and then install a number of reinforcing bolts 4 and fixing bolts 6, which can greatly reduce the time required for assembling the AGV wheels.

[0069] This embodiment also discloses a production process for AGV wheels, comprising the following steps: S1, manufacturing the first half wheel 1 and the second half wheel 2: processing a plurality of first brackets 12 on the first hub plate 11, and processing a plurality of second brackets 22 on the second hub plate 21.

[0070] Specifically, the processing steps for processing the first bracket 12 on the first hub plate 11 and the second bracket 22 on the second hub plate 21 are the same. When processing small batches or samples, laser cutting or wire cutting and bending are used; when processing large batches of products, stamping is used.

[0071] When processing a small batch or a sample, the steps for processing the first bracket 12 on the first hub plate 11 are as follows: S11 , machining a plurality of holes on the first hub plate 11 .

[0072] S12, cutting a plurality of first clearance plates 121, a plurality of first connecting plates 122 and a plurality of first fixing plates 123 from the first hub plate 11 by laser cutting or wire cutting.

[0073] S13, by means of bending processing, the first fixing plates 123 on the first hub plate 11 are bent in sequence, so that the first fixing plates 123 are perpendicular to the first hub plate 11; then the first connecting plates 122 are bent in sequence, so that the first connecting plates 122 are perpendicular to the first hub plate 11. Finally, the first fixing plates 123 are parallel to the first hub plate 11, and the first connecting plates 122 are perpendicular to the first hub plate 11.

[0074] Specifically, in order to ensure the bending effect, a clearance groove is pre-cut at the bending part of the first clearance plate 121 and the first connecting plate 122. Similarly, a clearance groove is pre-cut at the bending part of the first connecting plate 122 and the first fixing plate 123. After the clearance groove is cut, in order to ensure the connection strength between the first clearance plate 121, the first connecting plate 122 and the first fixing plate 123, welding reinforcement is performed at the connection between the first clearance plate 121 and the first connecting plate 122 and the connection between the first connecting plate 122 and the first fixing plate 123.

[0075] S2. A plurality of first supporting wheels 31 are installed on the first half wheel 1 side, and a plurality of second supporting wheels 32 are installed on the second half wheel 2 side.

[0076] S21, plug the corresponding connecting shaft 5 on the first connecting plate 122, and then weld the connecting shaft 5 to the first connecting plate 122; at the same time, plug the corresponding connecting shaft 5 on the second connecting plate 222, and then weld the connecting shaft 5 to the second connecting plate 222.

[0077] S22 , installing the first supporting wheel 31 on the connecting rotating shaft 5 on the first connecting plate 122 ; installing the second supporting wheel 32 on the connecting rotating shaft 5 on the second connecting plate 222 .

[0078] S3, assembling the first half wheel 1 and the second half wheel 2.

[0079] S31, aligning and buckling the first half wheel 1 and the second half wheel 2 coaxially, and making the first support wheel 31 and the second support wheel 32 alternately arranged in sequence along the circumference of the first half wheel 1.

[0080] S32, fixing the first hub plate 11 and the second hub plate 21.

[0081] Specifically, the first hub plate 11 and the second hub plate 21 are stably fixed by installing all the reinforcing bolts 4 and the fixing bolts 6 in sequence.

[0082] Specifically, when a plurality of first support wheels 31 and a plurality of second support wheels 32 are arranged relatively densely, if there is interference between the first support wheels 31 and the second support wheels 32, a first bracket 12 or a second bracket 22 is selected at this time, and the corresponding first giveway plate 121 or the second giveway plate 221 is bent so that the first half wheel 1 and the second half wheel 2 can be normally engaged. After the first half wheel 1 and the second half wheel 2 are completed in other places, the bent first giveway plate 121 or the second giveway plate 221 is bent back to its original position, and the corresponding reinforcement bolts 4 are installed to fix the bent first giveway plate 121 or the second giveway plate 221 tightly.

[0083] The implementation principle of the embodiment of the present application is: through the above-mentioned process, the production and assembly of the wheels for AGV can be realized, and because the first half wheel 1 and the second half wheel 2 can be processed at the same time, the first support wheel 31 on the first half wheel 1 and the second support wheel 32 on the second half wheel 2 can be installed at the same time, which can reduce the processing time of each component of the AGV wheel; and when assembling the AGV wheel, it is only necessary to coaxially splice the processed first half wheel 1 and the second half wheel 2, which can greatly reduce the requirements and difficulty of assembling the AGV wheel.

[0084] Embodiment 2: A wheel for AGV, referring to Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that a quick connection mechanism 7 is provided between the first support wheel 31 and the first connecting plate 122 and between the second support wheel 32 and the second connecting plate 222. In this embodiment, the first connecting plate 122 and the second connecting plate 222 have the same structure, and the two quick connection mechanisms 7 are also the same. The quick connection mechanism 7 on the first connecting plate 122 is taken as an example for description.

[0085] Reference Figure 7 and Figure 8 The quick-connect mechanism 7 includes a wheel seat 71, the connecting shaft 5 is fixed on the wheel seat 71, the wheel seat 71 is sleeved on the outer side of the corresponding first connecting plate 122, and the wheel seat 71 is plugged and matched with the corresponding first connecting plate 122 along the length direction of the corresponding first connecting plate 122.

[0086] Reference Figure 8 and Fig. 9 The inner wall of the wheel seat 71 is provided with a plurality of connecting columns 72, and the inner wall of the wheel seat 71 is provided with a plurality of floating holes 711. The floating holes 711 are arranged one by one with the connecting columns 72, and the connecting columns 72 are plugged and matched with the corresponding floating holes 711. The connecting columns 72 are slidably connected with the inner wall of the corresponding floating hole 711 along their own axial direction. A floating spring 73 is arranged between the connecting column 72 and the inner wall of the floating hole 711. The floating spring 73 is located in the floating hole 711, and the axial direction of the floating spring 73 is arranged along the axial direction of the floating hole 711. One end of the floating spring 73 is connected to the connecting column 72, and the other end is connected to the inner wall of the floating hole 711.

[0087] Reference Figure 7 and Fig. 9 The first connecting plate 122 has a plurality of connecting holes 1221, which are arranged one by one with the connecting posts 72, and the connecting posts 72 are plugged into and matched with the corresponding connecting holes 1221. In this embodiment, the number of the connecting holes 1221 is not less than two.

[0088] Reference Figure 7 and Fig. 9When the wheel seat 71 is sleeved on the corresponding first connecting plate 122, as the wheel seat 71 and the corresponding first connecting plate 122 slide relatively into place, the connecting column 72 is automatically inserted into the corresponding connecting hole 1221 under the action of the corresponding floating spring 73, which facilitates the rapid installation of the wheel seat 71 and the corresponding first connecting plate 122, and then facilitates the rapid installation of the connecting shaft 5 and the corresponding first connecting plate 122.

[0089] Reference Figure 7 and Fig. 9 The connection between the side of the connecting column 72 away from the floating spring 73 along its own axial direction and the outer wall of the connecting column 72 is rounded or chamfered. This makes it possible for the chamfered or rounded surface of the connecting column 72 to automatically contact the first connecting plate 122 when the wheel seat 71 is sleeved on the first connecting plate 122, so that the connecting column 72 is retracted into the corresponding floating hole 711, thereby facilitating the sleeve of the wheel seat 71 to the outer side of the corresponding first connecting plate 122, and preventing the connecting column 72 from affecting the installation of the wheel seat 71 sleeve.

[0090] Reference Fig. 9 A plurality of fine-tuning screws 74 are arranged on the outside of the wheel seat 71. The fine-tuning screws 74 are arranged one by one with the floating holes 711. The fine-tuning screws 74 are plugged into the corresponding floating holes 711. The fine-tuning screws 74 are connected to the inner wall of the corresponding floating holes 711 through threads, and one end of the fine-tuning screw 74 facing the first connecting plate 122 is arranged opposite to the corresponding connecting column 72. The floating spring 73 is sleeved on the outside of the corresponding fine-tuning screw 74, and the floating spring 73 and the fine-tuning screw 74 are arranged at intervals. Reference Figure 7 and Fig. 9 By loosening the fine-tuning screw 74, one end of the fine-tuning screw 74 is separated from the corresponding connecting column 72. At this time, the connecting column 72 cooperates with the floating spring 73 and can slide normally in the corresponding floating hole 711. Then, when the wheel seat 71 is mounted on the corresponding first connecting plate 122 or the second connecting plate 222, the connecting column 72 can float normally, ensuring that the connecting column 72 can be inserted into the corresponding connecting hole 1221, and the connecting column 72 can also slide out from the corresponding connecting hole 1221.

[0091] Reference Figure 7 and Fig. 9 After several connecting posts 72 are plugged into the corresponding connecting holes 1221, tighten the fine-tuning screw 74 so that one end of the fine-tuning screw 74 can contact the corresponding connecting post 72 or limit the sliding distance of the corresponding connecting post 72, ensuring that the connecting post 72 can always be plugged into the corresponding connecting hole 1221, thereby ensuring the stability of the connection between the wheel seat 71 and the corresponding first connecting plate 122 or the second connecting plate 222.

[0092] The implementation principle of the embodiment of the present application is: the corresponding first support wheel 31 or the second support wheel 32 is pre-installed on the corresponding wheel seat 71, and then when assembling the AGV wheel, it is convenient to quickly install the wheel seat 71 on the corresponding first bracket 12 or the second bracket 22, which facilitates the rapid assembly of the AGV wheel.
