Description

Technical Field

[0001] This application relates to the field of bearing processing technology, and in particular to a bearing feeding device. Background Technology

[0002] Wheel bearings are one of the key components of automobiles. Their main functions are to bear weight and provide precise guidance for the rotation of the wheel hub. In existing technology, bearings that need to be loaded are usually placed one by one on the surface of a conveyor belt, and then transported by the conveyor belt to the area where they can be held by the grippers. This method of loading results in low space utilization.

[0003] CN206780016U discloses a magnetic bearing feeder. When using this equipment, the worker needs to place the bearing on the feeding rail, and then activate the cylinder to push the bearing placed on the feeding rail into the conveying rail. The bearing will be conveyed to the processing area through the conveying rail. This feeding method has low space utilization. Summary of the Invention

[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a bearing feeding device.

[0005] This application can be achieved through the following technical solution: a bearing loading device, comprising a disc, limiting rods, grippers, and a driving device. The disc is used to stack several bearings; several limiting rods are provided and all pass through the disc, arranged around the center of the disc, and the disc is slidably connected to the limiting rods, allowing the bearings to contact several limiting rods simultaneously; the grippers are located on the side of the limiting rods facing away from the ground; the driving device is used to drive the disc to move vertically so that the grippers can clamp the bearings; wherein, the disc and the several limiting rods passing through the same disc constitute a bearing placement assembly, the bearing placement assembly having an array, and the array of bearing placement assemblies being driven cyclically by a conveying component so that the set of bearing placement assemblies can be located directly below the grippers.

[0006] In the above technical solution, several bearings can be stacked on a disc, and the drive device can drive the disc to move upward so that the bearings on the disc can be gripped by the grippers. The conveying component can cyclically convey the array of bearing placement components so that a group of bearing placement components is directly below the grippers. Compared with using a conveyor belt to convey the bearings to the area below the grippers, the stacking method in the same space has a higher space utilization rate.

[0007] Furthermore, it also includes a fixed frame and flip plates. Several flip plates are provided and hinged to the fixed frame. The lower surface of the flip plate can contact the fixed frame to make the flip plate horizontal. The bearing can contact the lower surfaces of several flip plates simultaneously to make several flip plates flip. The bearing can contact the upper surfaces of several flip plates. The gripper can hold the bearing that is in contact with the upper surface of the flip plate.

[0008] In the above technical solutions, some bearings have unique shapes, such as hub bearings. Due to their shape, which is smaller at the top and larger at the bottom, the bearing axis may become misaligned when stacked, making it difficult for the grippers to accurately hold the bearings. During the upward movement of the drive device on the disc, the top-ranked hub bearing contacts the lower surface of the flip plate, causing the flip plate to rotate at a certain angle. The disc continues to rise until the flip plate contacts the fixing frame again due to its own weight. At this point, the flip plate is horizontal, the top-ranked bearing detaches from the flip plate, and the next-highest-ranked bearing is below the flip plate. The drive device can then stop driving the disc upward. Subsequently, the drive device can drive the disc downward, and the top-ranked bearing will fall onto the flip plate due to its own weight. At this point, the bearing axis is perpendicular to the ground, ensuring that the grippers can accurately hold the bearing.

[0009] Furthermore, a stop block is integrally formed at the end of the flap that is away from the ground, and the bearing can simultaneously contact the upper surfaces of several flaps and several stop blocks.

[0010] In the above technical solution, the bearing can simultaneously contact the upper surfaces of several flip plates and several stops. The stops can further limit the bearing's position, thereby allowing the grippers to hold the bearing more accurately.

[0011] Furthermore, the disc has several adjustment slots through it, and several limiting rods are slidably connected to the several adjustment slots one by one. The several limiting rods are all slidably connected to a chassis, and the limiting rods are fixed to the chassis by limiting components. The flip plate and the fixing frame are detachably hinged.

[0012] In the above technical solution, the limiting rod can slide along the adjusting groove, so that bearings of different diameters can be accommodated among several limiting rods, thus broadening the application range. After the limiting rod is adjusted, the flap can be disassembled to replace the flap with one that has a different stop position, so that the position of the stop can be adapted to the position of the limiting rod.

[0013] Furthermore, the limiting component includes a sliding groove, a spring, and a fixing block. Several sliding grooves are formed on the chassis, each corresponding to a specific limiting rod. Several placement slots are formed along the length of the vertical sidewall of the sliding groove. A locking block with a hemispherical shape is slidably connected to each placement slot. The spring forces the locking block away from the bottom surface of the placement slot. Several fixing blocks are integrally formed with each limiting rod, each corresponding to a specific sliding groove. Each fixing block has a locking hole that engages with the locking block.

[0014] In the above technical solution, the fixing block is slid along the slide groove according to the diameter of the bearing. During the sliding process, the snap-fit ​​block can snap into the snap-fit ​​hole, and the fixing block can be fixed relative to the chassis position.

[0015] Furthermore, the driving device includes a mounting plate, a lead screw, a first bevel gear, a second bevel gear, a first motor, a position sensor, and a controller. The lower surface of the disk can contact the mounting plate; the lead screw is threadedly connected to the mounting plate; the first bevel gear is coaxially and fixedly installed with the lead screw; the second bevel gear meshes with the first bevel gear; the first motor is used to drive the second bevel gear to rotate, so that the mounting plate can drive the disk to move vertically in a straight line.

[0016] In the above technical solution, the motor can drive the second bevel gear to rotate, the rotation of the second bevel gear can drive the first bevel gear to rotate, so that the lead screw can rotate, and the rotation of the lead screw can drive the disk to move vertically and linearly, so that the bearing located on the disk moves upward.

[0017] Furthermore, it also includes a position sensor and a controller. The position sensor is used to detect the position of the bearing away from the ground; the controller is electrically connected to the position sensor and to the motor, so that when the bearing away from the ground is in a designated position, the motor can drive the bevel gear two to reverse.

[0018] In the above technical solution, when the bearing on the top layer moves to the designated position, the position sensor can feed back a signal to the controller, and the controller can control the motor to drive the bevel gear to reverse, so that the disc descends, and the position control of the bearing is more precise.

[0019] Furthermore, the conveying assembly includes a second motor and sprockets. Two sprockets are provided, and the two sprockets mesh with the same chain. The chain is fixedly connected to several chassis. The second motor drives the sprockets to rotate, so that the rotation of the sprockets can move a set of bearing placement assemblies in the array directly below the grippers.

[0020] In the above technical solution, the second motor can drive a sprocket to rotate so that the chain can be circulated and transmitted, thereby driving a set of bearing placement components in the array to be located directly below the gripper.

[0021] Furthermore, both sprockets are rotatably connected to a base, and the base is rotatably connected to several rollers, which make rolling contact with the chassis.

[0022] In the above technical solution, the roller can support the chassis and can make rolling contact with the chassis, which allows the chain to transport the bearing placement components more smoothly.

[0023] In summary, this application has the following technical advantages: several bearings can be stacked on a disc, and the drive device can drive the disc to move upward so that the bearings on the disc can be gripped by the grippers. The conveying assembly can cyclically convey the array of bearing placement assemblies so that a group of bearing placement assemblies is directly below the grippers. Compared with using a conveyor belt to convey bearings to the area below the grippers, the stacking method in the same space has a higher space utilization rate. Attached Figure Description

Detailed Implementation

[0026] Please refer to the attached diagram in the instruction manual. Figure 1 One embodiment of this application provides a bearing loading device, including an array of bearing placement components. The bearing placement components include a horizontally placed disc 1 and three limiting rods 3 slidably connected to the disc 1. The disc 1 can slide up and down along the length of the limiting rods 3. The three limiting rods 3 are all vertically placed and arranged around the center of the disc 1. Several bearings 2 are stacked on the disc 1. In this embodiment, the bearings 2 are hub bearings, and each bearing 2 can simultaneously contact all three limiting rods 3. A gripper 4 is provided on the side of each of the three limiting rods 3 facing away from the ground. The gripper 4 is used to grip the bearings 2 on the disc 1, one at a time. The disc 1 is driven vertically by a driving device 5, so that the bearings 2 located on the disc 1 can approach the gripper 4 and be gripped by the gripper 4. The gripper 4 can clamp the topmost bearing 2 to the processing position for further processing.

[0027] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 The array bearing 2 placement assembly is cyclically driven by a transmission assembly 6, so that a set of bearing placement assemblies can be positioned directly below the gripper 4. The transmission assembly 6 includes two sprockets 62, which are rotatably connected to the same base 15. The two sprockets 62 are engaged with the same chain 63, and the axes of the two sprockets 62 are perpendicular to the ground. One of the sprockets 62 is driven to rotate by a motor 61, so that the chain 63 can be cyclically driven. Three limiting rods 3, which are mounted on the same disc 1, are fixed to the same base 10. The base 10 is located below the disc 1 and is fixedly installed on the chain 63. The cyclical transmission of the chain 63 can drive one of the several bases 10 to be positioned directly below the gripper 4. Several rollers 16 are rotatably connected to the end of the base 15 that is away from the ground. The rollers 16 have rolling contact with the base 10 and can support the base 10. This design allows the chain 63 to rotate more smoothly.

[0028] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 The drive device 5 includes a motor 55, the output shaft of which is horizontal relative to the ground. A bevel gear 54 is coaxially fixedly mounted on the output shaft of the motor 55. The bevel gear 54 meshes with a bevel gear 53. The axis of the bevel gear 53 is perpendicular to the ground. A lead screw 52 is coaxially fixedly mounted on the bevel gear 53. The lead screw 52 is threadedly connected to a mounting plate 51. There are two of each of the following: motor 55, lead screw 52, ​​bevel gear 53, bevel gear 54, and mounting plate 51. The two mounting plates 51 can contact the lower surface of the disk 1. The motor 55 can drive the bevel gear 54 to rotate. The bevel gear 54, through the bevel gear 53 and the lead screw 52, ​​causes the mounting plates 51 to move the disk 1 up or down.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 4 Due to the special shape of the wheel hub bearing, the axis of the bearing 2 stacked on the disc 1 will be offset, which will cause the gripper 4 to be unable to accurately hold the bearing 2. A fixed frame 7 is placed next to the chain 63. The fixed frame 7 is detachably hinged with four flip plates 8. The four flip plates 8 are spaced apart and placed around the same circumference. The end of each of the four flip plates 8 facing away from the ground is integrally formed with a stop block 9. The four stop blocks 9 can contact the outer circumference of the same bearing 2. When the drive device 5 drives the disc 1 to move upward, the bearing 2 can contact the lower surface of the flip plate 8 so that the flip plate 8 rotates at a certain angle. The bearing 2 continues to rise until it no longer contacts the flip plate 8. At this time, the flip plate 8 contacts the fixed frame 7 again due to its own weight. At this time, the flip plate 8 returns to a horizontal state, and the bearing 2 of the second highest layer is located below the flip plate 8. At this time, the drive device 5 can drive the disc 1 to descend. At this time, the bearing 2 originally located on the highest layer can fall to the upper surface of the four flip plates 8 by gravity and simultaneously contact the vertical side wall of the stop block 9. At this time, the axis of the bearing 2 is perpendicular to the ground. The stop block 9 can limit the bearing 2 so that each bearing 2 falls to the same position on the surface of the flip plate 8. At this time, the gripper 4 can accurately clamp the bearing 2 located on the upper surface of the flip plate 8. The fixing frame 7 is fixedly installed with a position sensor 13, which can be an ultrasonic position sensor. The motor 55 is electrically connected to a controller 14, and the controller 14 is electrically connected to the position sensor 13. The position sensor 13 can detect the position of the bearing 2 so that after the bearing 2 moves to a specified height, the controller 14 can control the motor 55 to drive the bevel gear 54 to reverse. By setting the position sensor 13 and the position controller 14, the position control of the bearing 2 on the top layer can be made more accurate.

[0030] Please refer to the attached diagram in the instruction manual. Figure 3 and Figure 5 The disc 1 has three adjusting grooves 11 extending through its thickness. Three limiting rods 3 are slidably connected to the base 10. The three limiting rods 3 can slide along the length of the adjusting grooves 11 so that bearings 2 of different diameters can be accommodated between the three adjusting rods. The limiting rods 3 can be fixed to the base 10 by a limiting component 12.

[0031] Please refer to the attached diagram in the instruction manual. Figure 6 and Figure 7The limiting component 12 includes three sliding grooves 121 formed on the chassis 10. Three limiting rods 3 are slidably connected to the three sliding grooves 121, one-to-one. Each limiting rod 3 has an integrally formed fixing block 125, which is slidably connected to the sliding groove 121. Five placement slots 122 are formed along the length of the vertical sidewall of the sliding groove 121. The depth direction of the placement slots 122 is perpendicular to the width direction of the sliding groove 121. Each placement slot 122 is slidably connected to a locking block 123, which can slide along the depth direction of the placement slot 122. The locking block 123 is hemispherical in shape, and a spring 124 is provided inside the placement slot 122 to force the locking block 123 away from the bottom surface of the placement slot 122. The vertical sidewall of the fixing block 125 along its length has two snap-fit ​​holes 1251. These two snap-fit ​​holes 1251 can be matched one-to-one with two of the five snap-fit ​​blocks 123, and can contact the hemispherical surface to fix the position of the fixing block 125. The flip plate 8 and the fixing frame 7 are detachably hinged. The flip plate 8 can be detached to replace the flip plate 8 with one in a different position of the stop 9, so that the position of the stop 9 matches the position of the limiting rod 3, ensuring that the bearing 2 can still contact the vertical sidewall of the stop 9 after the position of the limiting rod 3 is adjusted.

[0032] The working principle of this embodiment is as follows: First, the bearings 2 are stacked on the disk 1. Then, the motor 55 is started to make the disk 1 rise. The bearings 2 of the highest layer can contact the lower surface of the flip plate 8 so that the flip plate 8 can be flipped at a certain angle. When the bearings 2 of the highest layer leave the flip plate 8, the flip can be reset to a horizontal state. At this time, the bearings 2 of the second highest layer are located below the flip plate 8. At this time, the position sensor 13 can send a signal to the controller 14. The controller 14 can control the output end of the motor 55 to reverse so that the disk 1 falls. At this time, the bearings 2 of the highest layer can contact the upper surface of several flip plates 8 and the vertical sidewall of several stops 9 due to their own gravity. At this time, the bearings 2 are horizontal relative to the ground, and the gripper 4 can hold the bearings 2 on the flip plate 8.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
