Description

Technical Field

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

[0002] In the field of machinery manufacturing and related equipment assembly, bearings are key mechanical components, and their assembly quality directly affects the operational accuracy, stability, and service life of the entire equipment. Bearings typically consist of components such as an inner shaft, outer ring, rolling elements, and cage. Among these, the inner shaft and outer ring are the core load-bearing structures of the bearing, and their assembly requires multiple processes, including handling, alignment, and installation.

[0003] Currently, in the bearing assembly process, manual handling remains the most common method for transporting the inner shaft and outer ring of the bearing, especially in small-batch production scenarios, customized assembly lines, or traditional manufacturing environments. However, manual handling is relatively inefficient and cannot meet the high-speed cycle requirements of modern production lines. Summary of the Invention

[0004] This disclosure provides a feeding device and a bearing assembly device to at least solve the above-mentioned technical problems existing in the prior art.

[0005] The first aspect of this disclosure provides a feeding device, including: a feeding tray and a conveying module;

[0006] The feeding tray is provided with multiple placement slots for placing the inner shaft or outer ring of the bearing, and the multiple placement slots are arranged sequentially along the first direction X;

[0007] The transport module includes a first drive member, a first slide rail, and a first slider. The first slide rail extends along the first direction X. The first slider slides in slidable engagement with the first slide rail. The first drive member is connected to the first slider and is used to drive the first slider to move along the first direction X. The first slider is provided with a gripper assembly for gripping the inner shaft of the bearing.

[0008] Furthermore, the feeding device also includes a moving mechanism, which is used to drive the feeding tray to move along the second direction Y.

[0009] Furthermore, the moving mechanism includes a second driving member, a second slide rail, and a second slider. The second slider is slidably engaged with the second slide rail. The second driving member is connected to the second slider and is used to drive the second slider to move along the second direction Y. The second slider is connected to the feeding tray, and a plurality of placement slots are arranged sequentially along the second direction Y.

[0010] Furthermore, the feeding device also includes a third guide rail and a third slider, wherein the third guide rail and the third slider are slidably engaged, and the third guide rail extends along the second direction Y.

[0011] Furthermore, the gripper assembly includes two first grippers and a drive cylinder for driving the first grippers. The drive cylinder is used to drive at least one of the two first grippers so that the two first grippers can move closer to or further away from each other.

[0012] Furthermore, the feeding tray is provided with a positioning frame, which is spaced apart from the feeding tray along the third direction Z. The positioning frame is provided with multiple positioning holes, which correspond one-to-one with the multiple placement slots.

[0013] Furthermore, a support column is provided between the feeding tray and the positioning frame, and the two ends of the support column are fixedly connected to the feeding tray and the positioning frame, respectively.

[0014] Furthermore, the plurality of placement slots are arranged in an array.

[0015] The second aspect of this disclosure provides a bearing assembly apparatus, including the feeding device described in the first aspect.

[0016] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0017] The feeding device provided in this embodiment includes a feeding tray and a conveying module. The feeding tray has multiple placement slots for placing the inner shaft or outer ring of a bearing, and the multiple placement slots are arranged sequentially along a first direction X. The conveying module includes a first driving member, a first slide rail, and a first slider. The first slide rail extends in the first direction X, and the first slider slides in cooperation with the first slide rail. The first driving member is connected to the first slider and is used to drive the first slider to move along the first direction X. The first slider is provided with a gripper assembly for gripping the inner shaft of the bearing. The feeding tray, through the multiple placement slots arranged sequentially along the first direction X, can realize the orderly storage and batch supply of the inner shaft or outer ring of the bearing, avoiding the limitation of single pick-up and drop during manual handling. In the conveying module, the first driving member drives the first slider to slide along the first slide rail extending in the first direction X, and cooperates with the gripper assembly on the slider to complete automatic gripping and transfer. The whole process does not require manual intervention and can operate stably according to a preset rhythm, effectively matching the high-efficiency assembly requirements of modern production lines, significantly improving the conveying rhythm of the inner shaft and outer ring of the bearing, and thus promoting the capacity improvement of the overall assembly process.

[0024] 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 a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0025] Combination Figure 1 and Figure 2As shown in the embodiments of this disclosure, the feeding device includes: a feeding tray 1 and a conveying module; the feeding tray 1 is provided with multiple placement slots 11 for placing the inner shaft 6 or outer ring of the bearing, and the multiple placement slots 11 are arranged sequentially along the first direction X; the conveying module includes a first driving member 21, a first slide rail 22 and a first slider 23, the first slide rail 22 extends along the first direction X, the first slider 23 slides in cooperation with the first slide rail 22, the first driving member 21 is connected to the first slider 23 and is used to drive the first slider 23 to move along the first direction X, and the first slider 23 is provided with a gripper assembly for gripping the inner shaft 6 of the bearing. The feeding tray 1, through the multiple placement slots 11 arranged sequentially along the first direction X, can realize the orderly storage and batch supply of the inner shaft or outer ring of the bearing, avoiding the limitation of single pick-up and drop during manual handling. In the conveying module, the sliding trajectory of the conveying module is along a fixed first direction X, and through the precise control of the first driving member 21, the positioning accuracy control after the gripper assembly grips the part can be realized, avoiding the positioning deviation caused by poor operation consistency during manual handling. The first driving component 21 drives the first slider 23 to slide along the first slide rail 22 extending in the first direction X. This, in conjunction with the gripper assembly on the slider, completes automatic gripping and transfer. The entire process requires no manual intervention and can operate stably according to a preset rhythm, effectively matching the high-efficiency assembly requirements of modern production lines. This significantly improves the handling rhythm of the bearing inner shaft and outer ring, thereby boosting the overall assembly capacity. The feeding device provided in this embodiment replaces traditional manual handling operations, especially for heavy or bulk bearing inner shafts and outer rings. It completely eliminates reliance on manual labor, avoids operator fatigue caused by prolonged handling, and reduces labor intensity.

[0026] Optionally, the first drive component 21 can be a cylinder, or it can be a combination of a motor, a lead screw and a nut.

[0027] In some specific embodiments, the feeding device further includes a moving mechanism, which drives the feeding tray 1 to move along the second direction Y. The moving mechanism drives the feeding tray 1 to move along the second direction Y, allowing the feeding tray 1 to arrange more placement slots 11 in a two-dimensional space. Optionally, based on the arrangement of multiple rows of placement slots 11 in the first direction X, the movement in the second direction Y enables the sequential switching of feeding from multiple rows of placement slots 11, breaking the capacity limitation of feeding from a single direction.

[0028] The moving mechanism and the handling module form a multi-dimensional linkage. The loading tray 1 moves along the second direction Y to switch the position of the placement slot 11, and the handling module moves along the first direction X to complete the grasping.

[0029] Optionally, once the components in a certain row of placement slots 11 have been picked up, the loading tray 1 moves in the Y direction to move the next row of placement slots 11 to the corresponding position. The handling module can continue picking up components without large-scale adjustments, which shortens the interval time of a single picking up and further improves the overall loading efficiency.

[0030] In some specific embodiments, the moving mechanism includes a second driving member 31, a second slide rail 32, and a second slider 33. The second slider 33 is slidably engaged with the second slide rail 32. The second driving member 31 is connected to the second slider 33 and is used to drive the second slider 33 to move along the second direction Y. The second slider 33 is connected to the loading tray 1, and multiple placement slots 11 are arranged sequentially along the second direction Y. The second slide rail 32 provides a stable guide for the movement of the second slider 33 along the second direction Y. Combined with the driving action of the second driving member 31, the second slider 33 can drive the loading tray 1 to achieve high-precision linear movement. This precise movement characteristic ensures that the multiple placement slots 11 arranged sequentially along the second direction Y can accurately reach the preset gripping position, allowing the gripper assembly to stably and reliably grip the inner shaft or outer ring of the bearing, reducing gripping errors caused by the movement deviation of the loading tray 1, and further ensuring the stability of the loading process.

[0031] Optionally, the second drive component 31 can be a cylinder or a combination of a motor, lead screw and nut.

[0032] In some specific embodiments, the feeding device further includes a third guide rail 34 and a third slider 35, with the third guide rail 34 and the third slider 35 in sliding engagement. The third guide rail extends along the second direction Y. The engagement of the third guide rail 34 and the third slider 35, together with the existing second guide rail 32 and the second slider 33, forms a double guide rail support structure along the second direction Y. This double support layout can effectively distribute the weight of the feeding tray 1 and the inner shaft and outer ring of the bearing it carries, preventing the feeding tray 1 from tilting or swaying due to unilateral force during movement.

[0033] In some specific embodiments, the gripper assembly includes two first grippers 71 and a drive cylinder 72 for driving the first grippers 71. The drive cylinder 72 is used to drive at least one of the two first grippers 71 so that the two first grippers 71 can move closer to or further away from each other.

[0034] The gripper assembly can stably grip the inner shaft or outer ring of the bearing. With the precise sliding of the first slide rail 22 and the first slider 23, it can ensure the smooth transfer of the parts during the transportation process. It avoids the problems of bumping and scratching the parts caused by uneven force or accidental slippage during manual handling. It effectively protects the surface quality and precision of the inner shaft and outer ring of the bearing, reduces the risk of parts being scrapped due to improper handling, and improves the pass rate of the parts.

[0035] In some specific embodiments, the loading tray 1 is equipped with a positioning frame 4, which is spaced apart from the loading tray 1 along the third direction Z. The positioning frame 4 has multiple positioning holes 41, which correspond one-to-one with multiple placement slots 11. When the inner shaft or outer ring of the bearing is placed in the placement slot 11, the positioning holes 41 on the positioning frame 4 can limit its position from the third direction Z, which can effectively prevent the bearing components from shifting due to vibration or shaking during handling or movement of the loading tray 1, ensuring that it is always in the preset accurate position, and providing a more accurate positioning reference for the subsequent gripper assembly to grasp.

[0036] Optionally, when the positioning bracket 4 places the bearing inner shaft 6, one end of the inner shaft can pass through the positioning hole 41 and abut against the placement groove 11.

[0037] In some specific embodiments, a support column 5 is provided between the feeding tray 1 and the positioning frame 4. Both ends of the support column 5 are fixedly connected to the feeding tray 1 and the positioning frame 4 respectively, which can prevent the positioning frame 4 from loosening or shifting due to vibration, impact, or other factors during equipment operation. This stable connection ensures that the positioning hole 41 and the placement slot 11 always maintain a precise one-to-one correspondence.

[0038] In some specific embodiments, multiple placement slots 11 are arranged in an array. This makes full use of the planar space of the loading tray 1, accommodating more bearing inner shafts or outer rings on the same area of ​​the loading tray 1. This efficient space utilization mode reduces the floor space occupied by the loading tray 1, while increasing the number of bearing components loaded at one time, further reducing the frequency of manual material replenishment and improving continuous feeding capability.

[0039] The bearing assembly device provided in this disclosure includes the feeding device provided in this disclosure. Since the bearing assembly device and the feeding device provided in this disclosure have the same advantages, they will not be described again here.
