[0116] The following further elaborates on the present disclosure in conjunction with the accompanying drawings and implementation modes. It can be understood that the specific implementation modes described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0117] It should be noted that, without conflict, the implementation modes in the present disclosure and the features in the implementation modes can be combined with each other. The following will elaborate on the technical solutions of the present disclosure with reference to the accompanying drawings and in conjunction with the implementation modes.

[0118] Unless otherwise specified, the exemplary implementation modes / embodiments shown will be understood to provide exemplary features of various details of some ways that can implement the technical concept of the present disclosure in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various implementation modes / embodiments can be additionally combined, separated, interchanged, and / or rearranged.

[0119] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement for the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of the components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences can be executed in an order different from that described. For example, two consecutively described processes can be executed substantially simultaneously or in an order opposite to that described. Moreover, the same reference numerals denote the same components.

[0120] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there may be intermediate components. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there are no intermediate components. For this reason, the term "connection" can refer to physical connection, electrical connection, etc., and can have or not have intermediate components.

[0121] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Additionally, the device can be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0122] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. Additionally, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but it does not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus they are used to account for the inherent deviations of measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0124] As Figure 1 shown, the automatic shaft component assembly system of the present disclosure may include components such as a workbench 100, a first assembly device 200, a second assembly device 300, and a third assembly device 400.

Figure 4 It is a schematic structural diagram of the first assembly tooling in the automatic assembly system of the shaft component according to an embodiment of the present disclosure. Figure 5 It is a schematic structural diagram of the first assembly tooling in the automatic assembly system of the shaft component according to an embodiment of the present disclosure from another angle.

[0127] As Figures 2 to 5 shown, the workbench 100 of the present disclosure is arranged substantially horizontally. Thus, the shaft component to be assembled in the present disclosure can be arranged substantially vertically, and the assembly of multiple shaft components is completed on the workbench 100.

[0128] Specifically, as Figure 2 and Figure 3 shown, components such as a first assembly device 200, a second assembly device 300, and a third assembly device 400 can be arranged on the workbench 100.

[0129] The first assembly device 200 is used to receive the first shaft component, and the first assembly device 200 can drive the first shaft component to rotate; the first shaft component in the present disclosure can include a first gear shaft and first bearings arranged at both ends of the gear shaft; and the first gear shaft may not be assembled with the first bearings together, but the assembly of the first gear shaft and the first bearings is realized through the first assembly device 200 of the present disclosure. Of course, the first assembly device 200 of the present disclosure can also be used to receive the first shaft component that has been assembled, that is, the first bearings of the first shaft component have been installed on the first gear shaft.

[0130] In a specific embodiment, the first assembly device 200 includes: a first assembly tooling 210 and a first pressing tooling 220; wherein, the first assembly tooling 210 is arranged on the workbench 100, and the first assembly tooling 210 is used to receive the first shaft component, and the first assembly tooling 210 can drive the first shaft component to rotate; the first pressing tooling 220 can be driven to move in a direction approaching or away from the first assembly tooling 210; wherein, the first pressing tooling 220 can press the first shaft component at a position close to the first assembly tooling 210.

[0131] More specifically, a first guide rail 230 is arranged on the workbench 100, and the first pressing tooling 220 is arranged to be able to be driven by a first pressing driving device 240 to slide along the first guide rail 230, wherein the first pressing driving device 240 is arranged on the workbench 100.

[0132] In the present disclosure, the first pressing drive device 240 may be a linear drive device, and the linear drive device may be selected from a cylinder, a hydraulic cylinder, or an electric cylinder. Specifically, the first pressing drive device 240 of the present disclosure may be a cylinder. Wherein, the cylinder block of the cylinder can be fixed to the workbench 100, and the piston rod of the cylinder is fixed to the first pressing tooling 220; and the sliding of the first pressing tooling 220 along the first guide rail 230 is realized by the telescopic movement of the cylinder.

[0133] In a specific embodiment, as Figure 4 and Figure 5 shown, the first assembly tooling 210 of the present disclosure may include components such as a cylinder body 211, a rotating rod 212, and a rotation drive device 213.

[0134] The cylinder body 211 is fixed to the workbench 100, and a counterbore is provided at the upper end of the cylinder body 211. The counterbore of the cylinder body 211 can accommodate and hold the lower first bearing of the first shaft component.

[0135] The rotating rod 212 is rotatably arranged in the cylinder body 211 and is located inside the cylinder body 211. For example, the rotating rod 212 can be rotatably supported on the inner wall of the cylinder body 211 through a bearing. The upper end of the rotating rod 212 of the present disclosure can be located outside the cylinder body 211. Correspondingly, when the first bearing or the first shaft component is supported by the cylinder body 211, at least a part of the upper end of the rotating rod 212 can be inserted into the inside of the first gear shaft and is in transmission connection with the first gear shaft. For example, the rotating rod 212 can be connected to the inner surface of the first gear shaft by key connection or by interference fit or other means. Specifically, the transmission connection method between the rotating rod 212 and the first gear shaft can be selected from a suitable connection method in the prior art according to the structure and other characteristics of the first gear shaft, and will not be elaborated one by one herein.

[0136] The rotation drive device 213 can be directly or indirectly fixed to the workbench 100 and can drive the rotating rod 212 to rotate. In the present disclosure, the rotation axis of the rotation drive device 213 coincides with the rotation axis of the rotating rod 212, and the rotation drive device 213 and the rotating rod 212 can be in transmission connection through an elastic coupling.

[0137] Referring again to Figure 2, the first pressing tooling 220 of the present disclosure includes: a first pressing base 221, a first pressing head component 222, and a first pressing head driving device 223; the first pressing base 221 is arranged to be slidable along the first guide rail 230, that is, the first pressing base 221 can be driven by the first pressing driving device 240 to move. The first pressing head driving device 223 is arranged on the first pressing base 221, and the first pressing head driving device 223 can be selected as a linear driving mechanism, such as a cylinder, a hydraulic cylinder, or an electric cylinder, etc. The first pressing head component 222 is rotatably arranged on the output shaft of the first pressing head driving device 223. Thus, the first pressing head component 222 can be driven by the first pressing head driving device 223 to generate a lifting motion in the vertical direction. That is to say, at this time, the first pressing head component 222 will be able to approach or move away from the first shaft component in the axial direction of the first shaft component. Correspondingly, when the first pressing head component 222 approaches the first shaft component, it can press the first shaft component from the upper end, or press the first bearing located above the first gear shaft into the first gear shaft.

[0138] Correspondingly, when the first shaft component is driven to rotate, since the first pressing head component 222 can rotate relative to the output shaft of the first pressing head driving device 223, correspondingly, the output shaft of the first pressing head driving device 223 will not rotate.

Of course, the second assembling device 300 of the present disclosure can also be used to receive the second shaft component that has been assembled, that is, the second bearings of the second shaft component have been installed on the second gear shaft.

[0142] In a specific embodiment, the second assembly device 300 includes: a second assembly tooling 310, a second pressing tooling 320, and a second guide rail 330; wherein, the second guide rail 330 is provided on the workbench 100, and the second assembly tooling 310 is configured to be driven by a second assembly driving device 340 to slide along the second guide rail 330; wherein, the second assembly tooling 310 is used to receive the second shaft component.

The second pressing head driving device 323 is arranged on the second pressing base 321, and the second pressing head driving device 323 can be selected as a linear driving mechanism, such as a cylinder, a hydraulic cylinder or an electric cylinder, etc. The second pressing head component 322 is rotatably arranged on the output shaft of the second pressing head driving device 323. Thus, the second pressing head component 322 can be driven by the second pressing head driving device 323 to generate a lifting movement in the vertical direction. That is to say, at this time, the second pressing head component 322 will be able to approach or move away from the second shaft component in the axial direction of the second shaft component. Correspondingly, when the second pressing head component 322 approaches the second shaft component, it can press the second shaft component from the upper end, or press the second bearing located above the second gear shaft into the second gear shaft.

[0148] Correspondingly, when the second shaft component is driven to rotate, since the second pressing head component 322 can rotate relative to the output shaft of the second pressing head driving device 323, correspondingly, the output shaft of the second pressing head driving device 323 will not rotate.

[0149] Figure 7 It is a schematic structural diagram of the third assembling device of the shaft component automatic assembling system according to an embodiment of the present disclosure.

[0150] The third assembling device 400 is used to receive the third shaft component, and the third assembling device 400 can drive the third shaft component to translate, and enable the third shaft component to move from the second receiving position to the second assembling position; wherein, the second receiving position is a position far from the second shaft component; the second assembling position is a position close to the second shaft component; and at the second assembling position, the second shaft component and the third shaft component are meshed.
