Description

Technical Field

[0001] This disclosure relates to the field of bearing assembly technology, and in particular to a handling device and a bearing assembly device. Background Technology

[0002] In the bearing manufacturing process, the bearing inner shaft, as a core component, directly affects the overall performance and service life of the bearing due to its dimensional accuracy, surface quality, and other parameters. Therefore, it requires multiple rigorous measurement processes for quality control. Typically, the bearing inner shaft needs to complete the testing of different parameters at different measurement stations. For example, basic dimensions such as outer diameter and length are measured at the first measurement station, and then geometric tolerances such as roundness and coaxiality are tested at the second measurement station.

[0003] In this process, accurately and efficiently transferring the bearing inner shaft from the first measuring station to the second measuring station is a crucial step in ensuring the smooth operation of the testing process. Traditional handling methods rely heavily on manual operation, which is labor-intensive, inefficient, and unsuitable for large-scale mass production. Summary of the Invention

[0033] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0034] Combination Figure 1 , Figure 2 and Figure 3As shown, the conveying device provided in this embodiment includes a first conveying module 1; the first conveying module 1 includes a lateral moving mechanism, a height adjusting mechanism, and multiple first gripper mechanisms; the lateral moving mechanism includes a first driving member 11 and a first moving member 12, the first driving member 11 is fixed to a bracket, and the driving end of the first driving member 11 is connected to the first moving member 12 for driving the first moving member 12 to move along a first direction X; the height adjusting mechanism includes a second driving member 21 and a second moving member 22, the second driving member 21 is connected to the first moving member 12, and the driving end of the second driving member 21 is connected to the second moving member 22 for driving the second moving member 22 to move along a height direction Z; multiple first gripper mechanisms are disposed on the second moving member 22, and the multiple first gripper mechanisms are spaced apart along the first direction X. The lateral moving mechanism drives the first moving member 12 to move along the X direction by the first driving member 11, and the height adjusting mechanism drives the second moving member 22 to move along the height direction by the second driving member 21. Through precise control of the driving members, precise planning of the conveying path can be achieved. Multiple first gripper mechanisms are spaced apart along the X direction. With the coordinated action of the lateral movement mechanism and the height adjustment mechanism, multiple bearings 9 can be transported simultaneously. This allows more bearings 9 to be transferred to different workstations in the same amount of time, significantly increasing the amount of material transported per unit time. It is especially suitable for efficient operation in mass production scenarios.

[0035] Optionally, the first direction X can be the length direction of the conveying device; the second direction Y can be the width direction of the conveying device; and the third direction Z can be the height direction of the conveying device.

[0036] In some specific embodiments, the first gripper mechanism includes a first clamping plate 31, a second clamping plate 32, and a third driving member 33. The third driving member 33 is connected to at least one of the first clamping plate 31 and the second clamping plate 32, and is used to drive at least one of the first clamping plate 31 and the second clamping plate 32 to move closer or further apart along a first direction X, thereby flexibly adjusting the distance between the two clamping plates. This allows the first gripper mechanism to be adaptively adjusted according to the outer diameter of the bearing 9, and can stably clamp both smaller and larger inner shafts of the bearing 9, greatly enhancing the gripper's adaptability to bearings 9 of different sizes. It eliminates the need to replace the gripper with a special gripper for inner shafts of bearings 9 of different sizes, reducing the equipment's operating costs and changeover time.

[0037] Optionally, the first drive component 11, the second drive component 21, and the third drive component 33 can all be cylinders.

[0038] In some specific embodiments, the first clamping plate 31 includes a first arcuate surface facing the second clamping plate 32, and the second clamping plate 32 includes a second arcuate surface facing the first clamping plate 31, with the second arcuate surface opposite to the first arcuate surface. The outer surface of the bearing 9 is typically cylindrical, and the first and second arcuate surfaces can better fit with the inner outer surface of the bearing 9. Compared to a flat clamping plate, the arcuate surface has a larger contact area with the cylindrical bearing 9, which can more evenly distribute the clamping force, reducing the possibility of rotation or displacement of the inner shaft of the bearing 9 during transportation, making the clamping more stable and reliable.

[0039] In some specific embodiments, a first positioning mechanism and a second positioning mechanism are also included. The first positioning mechanism is disposed on a first side of the lateral moving mechanism along the first direction X, and the second positioning mechanism is disposed on a second side of the lateral moving mechanism along the first direction X. The first positioning mechanism accurately positions the bearing 9 at its initial position during measurement, ensuring that the bearing 9 is accurately placed in the preset position each time the first gripper mechanism of the first conveying module 1 transports it to the first or second measuring station. The second positioning mechanism calibrates the end position of the bearing 9 after measurement, ensuring that the bearing 9 is accurately placed in the preset position each time, providing a solid foundation for the smooth progress of subsequent unloading or gripping processes.

[0040] In some specific embodiments, the first positioning mechanism includes a first pushing cylinder 41 and a first positioning seat 42. The first pushing cylinder 41 and the first positioning seat 42 are arranged opposite to each other in the second direction Y, and a first support seat 43 is provided between the first pushing cylinder 41 and the first positioning seat 42. When the bearing 9 is placed on the first positioning seat 42, the telescopic end of the first pushing cylinder 41 extends to push the bearing 9 to abut against the first positioning seat 42. The extension of the telescopic end of the first pushing cylinder 41 can push the bearing 9 towards the first positioning seat 42 in the second direction Y until the bearing 9 abuts against the first positioning seat 42. This active pushing method can eliminate the offset of the bearing 9 caused by positional deviation during placement, ensuring that the position of the bearing 9 in the Y direction is strictly defined, providing a precise reference position for the subsequent gripping operation of the lateral movement mechanism. This precise positioning provides a stable reference for the measuring equipment, ensuring the accuracy of the measurement data and avoiding measurement errors caused by the positional offset of the bearing 9.

[0041] In some specific embodiments, the second positioning mechanism includes a second push cylinder 51 and a second positioning seat 52. The second push cylinder 51 and the second positioning seat 52 are arranged opposite each other in the second direction Y. A second support seat 53 is provided between the second push cylinder 51 and the second positioning seat 52. When the bearing 9 is placed on the second positioning seat 52, the telescopic end of the second push cylinder 51 extends and pushes the bearing 9 to abut against the second positioning seat 52. After the inner shaft of the bearing 9 is transported to the second measuring station and placed on the second support seat 53, the telescopic end of the second push cylinder 51 extends and pushes the bearing 9 towards the second positioning seat 52 in the second direction Y until the bearing 9 abuts against the second positioning seat 52. This active pushing process can eliminate the positional deviation that may occur when the bearing 9 is placed, so that the position of the bearing 9 in the Y direction is accurately fixed, providing a solid foundation for the smooth progress of subsequent unloading or gripping processes, providing a unified positioning reference for the collaborative operation of each link, and greatly improving the stability and reliability of the entire handling and detection system.

[0042] In some specific embodiments, a second transport module 7 is also included. The second transport module 7 includes a first slide rail 61, a first slider 62, and a first cylinder 63. The first slider 62 is slidably engaged with the first slide rail 61, which extends along a first direction X. The first cylinder 63 is used to drive the first slider 62 to move along the first direction X. The first slider 62 is provided with a second slide rail 64, a second slider 65, and a second cylinder 66. The second slider 65 is slidably engaged with the second slide rail 64, which extends along a third direction Z. The second cylinder 66 is used to drive the second slider 65 to move along the third direction Z. The second slider 65 is provided with a second gripper mechanism. This combined movement method of X and Z directions allows the second gripper mechanism to reach more workstations with different heights and horizontal positions. It can not only assist the first transport module 1 in completing the transfer of the inner shaft of the bearing 9 after measurement, but also cope with more complex scenarios such as transporting the inner shaft of the bearing 9 from the measurement workstation to the storage area and assembly area, greatly improving the spatial adaptability of the device.

[0043] In some specific embodiments, the second gripper mechanism includes a third clamping plate 71, a fourth clamping plate, and a fourth driving member 72. The fourth driving member 72 is connected to at least one of the third clamping plate 71 and the fourth clamping plate, and is used to drive at least one of the third clamping plate 71 and the fourth clamping plate to move closer or further apart along a first direction X, thereby flexibly adjusting the distance between the two clamping plates. This allows the first gripper mechanism to be adaptively adjusted according to the outer diameter of the bearing 9, and can stably clamp both smaller and larger inner shafts of the bearing 9, greatly enhancing the gripper's adaptability to bearings 9 of different sizes. It eliminates the need to replace the gripper with a special gripper for inner shafts of bearings 9 of different sizes, reducing equipment operating costs and changeover time.

[0044] The fourth drive component 72 can be a cylinder.

[0045] The bearing assembly device provided in this disclosure includes the handling device provided in this disclosure. The bearing assembly device provided in this disclosure has the same advantages as the handling device provided in this disclosure.

[0046] In some specific embodiments, the bearing assembly device further includes a first measuring mechanism 81 and a second measuring mechanism 82. The first measuring mechanism 81 and the second measuring mechanism 82 are spaced apart along a first direction X, and both the first measuring mechanism 81 and the second measuring mechanism 82 are located on one side of the first transport module 1. The first measuring mechanism 81 and the second measuring mechanism 82 are spaced apart along the X direction and concentrated on one side of the first transport module 1, so that the measuring area and the transport area form a compact integrated layout, reducing the space occupied by the equipment in the production workshop. Since the two measuring mechanisms are spaced apart along the X direction and are located on the same side of the first transport module 1, the lateral moving mechanism of the first transport module 1 can move back and forth directly between the two along the X direction, and the first gripper mechanism can quickly transfer the inner shaft of the bearing 9 from the first measuring mechanism 81 to the second measuring mechanism 82. This close-range, same-direction layout significantly shortens the transport path, reduces transport time, makes the measurement process and the transport process more closely connected, avoids process jams caused by the dispersed distribution of mechanisms, and significantly improves the overall operation efficiency.

[0047] The first measuring mechanism 81 and the second measuring mechanism 82 can be either inner shaft channel measuring mechanisms or outer ring channel measuring mechanisms. The first measuring mechanism 81 forms a first measuring station, and the second measuring mechanism 82 forms a second measuring station.

[0048] Optionally, both the first measuring mechanism 81 and the second measuring mechanism 82 may include a channel diameter measuring component, such as a channel diameter measuring instrument composed of two symmetrically distributed probes. The probes can extend into the channel to acquire channel diameter data in real time through a contact measurement method.

[0049] Optionally, both the first measuring mechanism 81 and the second measuring mechanism 82 can be groove roundness measuring components, which consist of a high-precision rotating shaft and a groove-specific probe. After the inner shaft of the bearing 9 is fixed, the rotating shaft drives the probe to move around the groove circumference. The probe collects the contour changes of the groove surface and then analyzes and obtains the groove roundness error.

For example, the steps described in this invention disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this embodiment can be achieved, and this is not limited herein.
