Description

Technical Field

[0001] This utility model relates to the field of axle manufacturing, and in particular to a roller axle shell feeding device and a roller axle shell feeding system. Background Technology

[0002] The axle is a crucial component of a vehicle. It connects the wheels and, through the suspension system, is linked to the chassis or monocoque body, playing multiple vital roles. The axle not only bears the weight and various loads of the vehicle, ensuring its stability, but also maintains a certain relative movement between the wheels and the body, ensuring normal vehicle movement on the road. Furthermore, the axle supports the body, preventing excessive deformation, and distributes the vehicle's load proportionally to the wheels, reducing tire wear.

[0003] To facilitate axle assembly, an axle typically consists of two interlocking axle housings, with the power transmission structure installed between them. The axle housings are pre-produced and stored in a material warehouse. During axle assembly, they are transported to the assembly station using forklifts or other transport vehicles. In highly automated production lines, the axle housings are conveyed via a conveyor line; a certain number of axle housings are placed on transfer trolleys, which are then driven by the conveyor line to the picking location.

[0004] On automated conveyor lines, it can be seen that the transfer trolleys carrying multiple bridge shells have a large overall mass, and are prone to deviating from the conveyor line during long-distance continuous transportation. Summary of the Invention

[0005] This invention addresses the problem of misalignment that easily occurs when conveying bridge shells on current bridge shell conveyor lines by providing a ground roller bridge shell feeding device.

[0006] To address the aforementioned problems, this utility model employs a technical solution: a ground roller bridge shell feeding device, comprising a frame, with multiple roller groups arranged on the upper surface of the frame. Each roller group includes multiple rollers and a drive assembly for driving the rollers. A first position sensor is installed on the frame corresponding to each roller group, located at the end of the roller group along the transmission direction and electrically connected to the drive assembly of the next roller group. This feeding device adopts a segmented conveying method, with position sensors installed at the rear end of each roller group segment. The ground roller conveying trolley controls the start of the next roller group segment upon reaching the end of each segment, thus avoiding deviation by dividing the journey into segments.

[0007] As a preferred implementation of the roller bridge shell feeding device, the frame is also equipped with guide limiting blocks corresponding to each roller group, and the guide limiting blocks are located on both sides of the front roller of the roller group. At the front end of each roller group, the guide limiting blocks realize the correction of deviation, further preventing the trolley from running off-track.

[0008] As a preferred embodiment of the ground roller bridge shell feeding device, the frame is provided with a first side plate and a second side plate, the roller is installed between the first side plate and the second side plate, the top of the outer peripheral surface of the roller is higher than the upper edge of the first side plate and the second side plate, and the first position sensor and the guide limit block are installed on the first side plate and the second side plate.

[0009] In a preferred embodiment of the roller bridge shell feeding device, the rollers are arranged in two rows. A first support plate and a second support plate are also provided between the first side plate and the second side plate. The two rows of rollers are respectively installed between the first side plate and the first support plate and between the second side plate and the second support plate. This provides support to both sides of the bottom of the trolley, preventing deviation caused by excessive contact area between the trolley and the rollers.

[0010] As a preferred embodiment of the roller bridge shell feeding device, the drive assembly includes a motor. Motor supports are respectively provided on the frame corresponding to each roller group. The motor is mounted on the motor supports. In each roller group, the ends of two adjacent rollers are connected by a transmission chain. The output shaft of the motor is directly or indirectly connected to one of the rollers via a drive chain. Each roller is connected by a chain to achieve synchronous rotation, resulting in smoother and more precise conveying.

[0011] As a preferred embodiment of the ground roller bridge shell feeding device, a drive shaft is also provided on the frame corresponding to each roller group area. The output shaft of the motor is connected to the drive shaft and drives the drive shaft to rotate. The drive chains are respectively provided at both ends of the drive shaft, and the drive chains at both ends are connected to the two rows of rollers. The rollers on both sides are driven synchronously by the drive shaft to achieve uniform speed on both sides.

[0012] As a preferred embodiment of the ground roller bridge shell feeding device, one end of the drive shaft is rotatably mounted on the motor bracket, and a support seat is provided on the opposite side of the motor bracket on the frame, and the other end of the drive shaft is rotatably mounted on the support seat.

[0013] In a preferred embodiment of the roller bridge shell feeding device, a second position sensor is also provided at the end of the frame along the transmission direction. The second position sensor is electrically connected to the drive assembly of the roller group located at the end. When the trolley runs to the end of the feeding device, the roller group is controlled to stop rotating.

[0014] On the other hand, this utility model also provides a ground roller bridge shell feeding system, which adopts the above-mentioned ground roller bridge shell feeding device.

[0015] As a preferred implementation of a roller bridge shell feeding system, the roller bridge shell feeding device is provided in multiple sets, arranged in parallel. A return conveyor line is located at the rear end of each set of feeding devices, perpendicular to the feeding devices. The feeding system enables multi-row feeding and also features a return conveyor line to return empty feeding trolleys, improving automation.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are as follows: The roller bridge shell feeding device of this utility model effectively solves the problem of trolley deviation during the conveying process by adopting a segmented conveying method and setting position sensors at the end of each roller group, thus improving the accuracy and stability of the conveying. Simultaneously, by setting guide limit blocks at the front end of each roller group, trolley deviation is further prevented, ensuring smooth conveying. Furthermore, the design of the rollers being installed between the side plates, with the top of the rollers higher than the upper edge of the side plates, combined with the position sensors and guide limit blocks, enhances the stability and reliability of the device. The double-row support design reduces the contact area between the trolley and the rollers, lowering the risk of deviation. The drive assembly is connected by a chain, achieving synchronous rotation of each roller, making the conveying more stable and precise. The rollers on both sides are synchronously driven by a transmission shaft, ensuring uniform operating speed. The second position sensor at the end can control the roller group to stop rotating when the trolley reaches the end, improving the degree of automation. The roller bridge shell feeding system adopts multiple sets of feeding devices set in parallel and is equipped with a return conveyor line, realizing multi-carriage feeding and empty car recovery, which greatly improves production efficiency.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] Example 1

[0025] like Figure 1 , 2 As shown, a ground roller bridge shell feeding device includes a frame 1, which is a cubic frame structure. The upper surface of the frame 1 is provided with multiple roller groups. Each roller group includes multiple rollers 4 and a driving assembly for driving the multiple rollers 4. Specifically, the frame 1 is provided with a first side plate 2 and a second side plate 3. A first support plate and a second support plate are also provided between the first side plate 2 and the second side plate 3. The rollers 4 are arranged in two rows. The two rows of rollers 4 are respectively installed between the first side plate 2 and the first support plate and between the second side plate 3 and the second support plate. The two ends of one row of rollers 4 are rotatably connected to the first side plate 2 and the first support plate, respectively. The two ends of the other row of rollers 4 are rotatably connected to the second side plate 3 and the second support plate, respectively. The top of the outer circumference of the rollers 4 is higher than the upper edge of the first side plate 2 and the second side plate 3.

[0026] Alternatively, a single, continuous roller 4 can be used, installed between the first side plate 2 and the second side plate 3, with both ends directly rotatably connected to the first side plate 2 and the second side plate 3.

[0027] A first position sensor 8 is provided on the frame 1 for each roller group. The first position sensor 8 can be an infrared sensor, proximity switch, etc. Along the transmission direction, the first position sensor 8 is located at the end of the roller group and is electrically connected to the drive assembly of the next roller group. A guide limit block 9 is also provided on the frame 1 for each roller group. The guide limit block 9 is located on both sides of the front roller of the roller group. The first position sensor 8 and the guide limit block 9 are mounted on the first side plate 2 and the second side plate 3.

[0028] like Figure 2As shown, the drive assembly includes a motor 5. Motor supports 6 are respectively provided on the frame 1 for each roller group. The motor 5 is mounted on the motor supports 6. In each roller group, the ends of two adjacent rollers 4 are connected by a transmission chain 11. The output shaft of the motor 5 is directly or indirectly connected to one of the rollers 4 by a drive chain 12. Furthermore, a transmission shaft 7 is also provided on the frame 1 for each roller group. The output shaft of the motor 5 is connected to the transmission shaft 7 and drives the transmission shaft 7 to rotate. The two ends of the transmission shaft 7 are respectively provided with the drive chains 12, which are respectively connected to two rows of rollers 4. One end of the transmission shaft 7 is rotatably mounted on the motor supports 6. A support base 10 is also provided on the opposite side of the motor supports 6 on the frame 1, and the other end of the transmission shaft 7 is rotatably mounted on the support base 10.

[0029] Along the transmission direction, a second position sensor is also provided at the end of the frame 1, and the second position sensor is electrically connected to the drive assembly of the roller group located at the end.

[0030] The bottom of the frame has multiple support feet, and the lower end of the support feet is equipped with anchor bolts for leveling the frame.

[0031] When this feeding device is in operation, the feeding trolley runs along the feeding device. Starting from one end of the device, the roller assembly begins to move and transport the feeding trolley, while the roller assemblies behind it remain stationary. When the feeding trolley reaches the rear end of the current roller assembly, the first position sensor is triggered, and the next roller assembly begins to move, continuing to transport the trolley. In this way, the feeding device operates in a segmented transport configuration, reducing the risk of the feeding trolley deviating from its designated position. Furthermore, if the feeding trolley does deviate from its designated position, a guide limit block is installed at the front end of each roller assembly to guide the trolley back to the correct position.

The ground roller bridge shell feeding device is provided in multiple sets, and the multiple sets of ground roller bridge shell feeding devices are arranged in parallel. A return conveyor line 13 is provided at the rear end of the multiple sets of ground roller bridge shell feeding devices. The return conveyor line 13 is perpendicular to the ground roller bridge shell feeding device. The return conveyor line 13 can adopt the same structure as the feeding device, or other transmission belt or roller conveyor structures.

[0034] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: the feeding device, by adopting a segmented conveying method and setting a position sensor at the end of each roller group, effectively solves the problem of trolley deviation during the conveying process, improving the accuracy and stability of the conveying. Simultaneously, by setting a guide limit block at the front end of each roller group, trolley deviation is further prevented, ensuring smooth conveying. Furthermore, the design of the rollers being installed between the side plates, with the top of the rollers higher than the upper edge of the side plates, combined with the position sensor and guide limit block, enhances the stability and reliability of the device. The double-row support design reduces the contact area between the trolley and the rollers, lowering the risk of deviation. The drive assembly is connected by a chain, achieving synchronous rotation of each roller, making the conveying more stable and precise. The rollers on both sides are synchronously driven by a transmission shaft, ensuring uniform operating speed. The second position sensor at the end can control the roller group to stop rotating when the trolley reaches the end, improving the degree of automation. The roller bridge shell feeding system adopts multiple sets of feeding devices set in parallel and is equipped with a return conveyor line, realizing multi-carriage feeding and empty car recovery, which greatly improves production efficiency.
