Description

Technical Field

[0001] The invention relates to the technical field of wheel hub production, and in particular to a transfer pallet for a wheel hub. Background Art

[0002] The wheel hub, also known as the rim, steel ring, etc., is a metal part that supports the tire with its inner profile and is mounted on the axle. It mainly plays the role of load bearing and steering, and its performance affects many driving characteristics of the car. The wheel hub has a long history. There were many shapes of ancient wheel hubs. After the patent of pneumatic tire appeared in 1888, the wheel hub and tire gradually evolved into what they are today. In the 1920s, aluminum alloy wheels were used in racing cars, and became popular in the 1960s. In the 1990s, China introduced its production technology.

[0003] During the production of wheel hubs, pallets are needed for transportation. However, the current pallet structure is relatively simple and does not have a structure to limit the wheel hub. This may cause the wheel hub to slide off the top of the pallet due to shaking or tilting of the pallet during transportation, thereby causing damage to the wheel hub. At the same time, most of the current pallets do not have a mobile structure and can only be transported by forklifts. When the number of wheel hubs produced is small, it will cause a waste of resources, thereby increasing production costs. Finally, when stacking, the current pallets are only limited and fixed by the limit grooves on the top and the limit blocks on the bottom. This fixing method is relatively simple and not stable enough. When a forklift transports it, the upper pallet may tilt and slide due to shaking or uneven ground, thereby causing damage to the wheel hub. Therefore, the present application proposes a transfer pallet for wheel hubs to meet the needs. Summary of the invention

[0013] The present invention has the following advantages: 1. The present invention provides a limiting assembly, and a driving block slides along the driving groove to drive the swivel and the top block to rotate in the cavity. When the top block contacts the connecting block, the connecting block will be pushed out toward the center of the cavity, and the connecting block will drive the first sliding block to slide along the first sliding groove and squeeze the first spring. When the limiting rod moves synchronously with the connecting block to closely fit with the inner wall of the adjusting groove close to the center of the cavity, the wheel hub is placed on the outer periphery of the limiting rod, and then the driving block is released. The first spring rebounds without force and drives the connecting block to move in a direction away from the center of the cavity through the first sliding block. When the limiting rod moves synchronously with the connecting block until the rubber pad is closely fitted with the inner wall of the wheel hub, the wheel hub can be limited. This design enables the pallet to limit wheel hubs of different sizes, effectively preventing the wheel hub from slipping and causing damage during transportation.

[0014] 2. The present invention is provided with a switching component. If the number of wheel hubs is large and the pallets need to be stacked, the insertion rod is moved out from the two horizontal groups of holes, and then the support is rotated to make it perpendicular to the ground. In this process, the mounting block drives the roller to rotate synchronously with the support and sink into the empty groove for storage. Then the insertion rod is inserted into the two vertical groups of holes so that the support can be fixed at the current angle through the mounting block. At this time, the pallet can be switched to a fixed posture. If the number of wheel hubs is small and only one group of pallets is needed for transportation, the insertion rod is moved out from the two vertical groups of holes, and then the support is rotated to drive the mounting block and the roller to rotate synchronously. When the roller is perpendicular to the ground, the insertion rod is inserted into the two horizontal groups of holes so that the mounting block is fixed in the current position. At this time, the pallet can be moved by the roller. This design enables the pallet to switch between a fixed posture and a mobile posture, so that it can be suitable for the transportation of different numbers of wheel hubs.

[0015] 3. The present invention is provided with a fixing component. After the pallet is switched to a fixed posture, the second group of pallets is placed above the first group of pallets and the support is inserted into the fixing groove of the mounting seat. During this process, since the longitudinal section of the fixing rod is a right-angled trapezoid, the fixing rod will be pushed outward by the support and squeeze the second spring through the second slider. When the support moves to the point where the fixing hole and the fixing rod are on the same axis, the second spring rebounds and drives the fixing rod to move inward through the second slider. When the fixing rod is inserted into the fixing hole, the support can be fixed in the fixing groove. At this time, the stacking of the two groups of pallets can be completed. When it is necessary to release the stacking of the pallets, the pull block is pulled outward to drive the fixing rod to move outward until it is moved out of the fixing hole, and then the pallet is lifted upward until the support is moved out of the fixing groove. At this time, the release of the two groups of pallets can be completed. This design can make the stacking between the pallets more stable and effectively prevent the upper pallet from tilting and sliding during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0019] A transfer pallet for a wheel hub comprises a pallet 1, a plurality of groups of limit components 2 are arranged on the top of the pallet 1, supports 3 for supporting the pallet 1 are arranged at the four corners of the bottom of the pallet 1, a switching component 4 is arranged at the connection between the support 3 and the pallet 1, and mounting seats 5 are fixedly connected to the four corners of the top of the pallet 1, and a fixing component 6 is arranged inside the mounting seat 5.

[0020] It should be noted that the limiting component 2 enables the pallet 1 to fix wheels of different sizes, thereby preventing the wheels from falling off and causing damage during transportation. The switching component 4 can adjust the angle of the support 3, thereby switching the fixed posture and the mobile posture of the pallet 1, so that it can be moved without a forklift when transporting fewer wheels. The fixing component 6 can make the connection between each two groups of pallets 1 more stable when the pallets 1 are stacked, thereby preventing the pallets 1 from tipping over.

[0021] like Figure 1 and Figure 2 As shown, the limiting assembly 2 includes an adjusting slot 21 , a limiting rod 22 and a rubber pad 23 . The adjusting slot 21 is opened on the top of the tray 1 , the limiting rod 22 is slidably connected to the adjusting slot 21 , and the rubber pad 23 is fixedly connected to the outer surface of the limiting rod 22 .

[0022] It should be noted that the position of the limiting rod 22 can be adjusted by pushing the limiting rod 22 along the adjusting groove 21 , so that it can limit the wheel hubs of different sizes.

[0023] like Figure 3 and Figure 4 As shown, the limit assembly 2 also includes a cavity 24, a connecting block 25, a first slide groove 26, a first slider 27 and a first spring 28. The cavity 24 is opened inside the tray 1 and is connected to the adjustment groove 21. The connecting block 25 is fixedly connected to the bottom of the limit rod 22 and is slidably connected to the cavity 24. The first slide groove 26 is opened on the inner wall of the bottom of the cavity 24 and is below the connecting block 25. The first slider 27 is fixedly connected to the bottom of the connecting block 25 and is slidably connected to the first slide groove 26. The first spring 28 is installed inside the first slide groove 26 and its two ends are respectively fixedly connected to one side of the first slider 27 close to the center of the cavity 24 and the inner wall of one side of the first slide groove 26 close to the center of the cavity 24.

[0024] It should be noted that sliding the connecting block 25 toward the center of the cavity 24 can drive the first slider 27 to slide synchronously along the first slide groove 26 and squeeze the first spring 28. When the first slider 27 is released, the first spring 28 rebounds and drives the connecting block 25 to move away from the center of the cavity 24 through the first slider 27.

[0025] like Figure 2 and Figure 3 As shown, the limit assembly 2 also includes a swivel 29, a top block 210, a drive groove 211 and a drive block 212. The swivel 29 is rotatably connected to the cavity 24, the top block 210 is fixedly connected to a side of the swivel 29 close to the limit rod 22, the drive groove 211 is opened at the top of the tray 1 and communicates with the cavity 24, and the drive block 212 is fixedly connected to the top of the swivel 29 and slidably connected to the drive groove 211.

[0026] It should be noted that the driving block 212 can be slid along the driving groove 211 to drive the rotating ring 29 and the top block 210 to rotate synchronously in the cavity 24 .

[0027] like Figure 5 and Figure 6 As shown, the switching assembly 4 includes an empty slot 41, a rotating slot 42 and a rotating shaft 43. The empty slot 41 is opened at the four corners of the bottom of the tray 1, and the rotating slot 42 is opened on the inner walls on both sides of the empty slot 41. The rotating shaft 43 is fixedly connected to both sides of the inner end of the support 3 and is rotatably connected to the rotating slot 42.

[0028] It should be noted that rotating the rotating shaft 43 along the rotating groove 42 can drive the support 3 to rotate synchronously in the empty groove 41, so as to adjust the angle of the support 3.

[0029] like Figure 5 and Figure 6 As shown, the switching assembly 4 also includes a mounting block 44, a roller 45, a socket 46 and an insertion rod 47. The mounting block 44 is fixedly connected to the bottom of the support 3, the roller 45 is installed at the bottom of the mounting block 44, the socket 46 is provided with two horizontal groups and two vertical groups and passes through the inner wall of one side of the empty slot 41 and the mounting block 44, and the insertion rod 47 is provided with two groups and is movably connected to the socket 46.

[0030] It should be noted that the angle of the mounting block 44 can be adjusted by removing the insertion rod 47 from the insertion hole 46, and the mounting block 44 can be fixed at the current angle by inserting the insertion rod 47 into the insertion hole 46.

[0031] like Figure 6 and Figure 7 As shown, the fixing assembly 6 includes a fixing groove 61, a fixing hole 62, a through groove 63 and a fixing rod 64. The fixing groove 61 is opened at the top of the mounting seat 5 and is adapted to the size of the support 3. The fixing hole 62 runs through the support 3. The through groove 63 runs through the inner wall of one side of the fixing groove 61. The fixing rod 64 is movably connected to the through groove 63 and is adapted to the size of the fixing hole 62. The longitudinal section of the fixing rod 64 is a right-angled trapezoid.

[0032] It should be noted that after the support 3 is inserted into the fixing groove 61 , the fixing rod 64 is inserted into the fixing hole 62 to fix the support 3 in the fixing groove 61 , thereby enhancing the connection strength between the two groups of trays 1 .

[0033] like Figure 7As shown, the fixing assembly 6 also includes a second slide groove 65, a second slider 66, a second spring 67 and a pull block 68. The second slide groove 65 is opened on the inner wall of the through groove 63. The second slider 66 is fixedly connected to the outer periphery of the fixing rod 64 and is slidably connected to the second slide groove 65. The second spring 67 is sleeved on the outer periphery of the fixing rod 64 and its two ends are respectively fixedly connected to the side of the second slider 66 away from the fixing groove 61 and the inner wall of the side of the second slide groove 65 away from the fixing groove 61. The pull block 68 is fixedly connected to the outer end of the fixing rod 64.

[0034] It should be noted that by pulling the pull block 68 outward, the second slider 66 can be driven to slide outward along the second slide groove 65 through the fixed rod 64 and squeeze the second spring 67. By releasing the pull block 68, the second spring 67 rebounds and drives the fixed rod 64 to move inward through the second slider 66.

[0035] In a specific application scenario, when the wheel hub needs to be transported, the driving block 212 is first slid along the driving groove 211 to drive the swivel 29 and the top block 210 to rotate in the cavity 24. When the top block 210 contacts the connecting block 25, the connecting block 25 will be pushed out to the center of the cavity 24. The connecting block 25 drives the first sliding block 27 to slide along the first sliding groove 26 and squeeze the first spring 28. When the limiting rod 22 moves synchronously with the connecting block 25 to fit closely with the inner wall of the side of the adjusting groove 21 close to the center of the cavity 24, the wheel hub is placed on the outer periphery of the limiting rod 22, and then the driving block 212 is released. The first spring 28 rebounds without force and is driven by the first sliding block 27. The movable connecting block 25 moves in the direction away from the center of the cavity 24. When the limiting rod 22 moves synchronously with the connecting block 25 until the rubber pad 23 is tightly fitted with the inner wall of the hub, the hub can be limited. Then, the fixed posture and moving posture of the pallet 1 are adjusted according to the number of transfer hubs required. If the number of hubs is large and the pallets 1 need to be stacked, the insertion rod 47 is moved out from the two horizontal groups of holes 46, and then the support 3 is rotated to make it perpendicular to the ground. In this process, the mounting block 44 drives the roller 45 to rotate synchronously with the support 3 and sink into the empty groove 41 for storage. Then, the insertion rod 47 is inserted into the two vertical groups of holes 46 so that the support 3 is fixed through the mounting block 44. The tray 1 is fixed at the current angle, at which time the tray 1 can be switched to a fixed posture, and then the second group of trays 1 is placed above the first group of trays 1 and the support 3 is inserted into the fixing groove 61 of the mounting seat 5. In this process, since the longitudinal section of the fixing rod 64 is a right-angle trapezoid, the fixing rod 64 will be pushed outward by the support 3 and squeeze the second spring 67 through the second slider 66. When the support 3 moves to the fixing hole 62 and the fixing rod 64 are on the same axis, the second spring 67 rebounds and drives the fixing rod 64 to move inward through the second slider 66. When the fixing rod 64 is inserted into the fixing hole 62, the support 3 can be fixed in the fixing groove 61. At this time, the two groups of trays can be completed. The stack of trays 1, when it is necessary to release the stack of trays 1, pull the pull block 68 outward so that it drives the fixing rod 64 to move outward until it moves out of the fixing hole 62, and then lift the tray 1 upward until the support 3 moves out of the fixing groove 61. At this time, the two groups of trays 1 can be released. If the number of hubs is small and only one group of trays 1 is needed for transportation, move the insertion rod 47 out of the two vertical groups of holes 46, and then rotate the support 3 to drive the mounting block 44 and the roller 45 to rotate synchronously. When the roller 45 is perpendicular to the ground, insert the insertion rod 47 into the two horizontal groups of holes 46 to fix the mounting block 44 in the current position. At this time, the tray 1 can be moved by the roller 45.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
