[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] The following further elaborates on the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the relevant utility model are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] The present utility model provides a vertical bearing two-way press-fitting device, as Figures 1 to 5 shown, for two-way press-fitting of bearings 200 at both axial ends of a workpiece 100.

[0032] It includes a base device 1 and a press-fitting device 2 with a press-fitting stroke arranged on the top of the base device 1.

[0033] The base device 1 includes a base main body 10 and a pre-installed lifting mechanism 3 with a lifting stroke arranged on the base main body 10. The pre-installed lifting mechanism 3 includes a bearing carrier 31 and a bushing ejector rod 32 with a lifting and floating displacement penetrating the bearing carrier.

[0034] The press-fitting device 2 includes a press-fitting carrier 4 connected to a lifting drive source. There is a bearing press-fitting seat 41 on the press-fitting carrier 4 and a bushing press-connecting rod 42 with a lifting and floating displacement penetrating the bearing press-fitting seat.

[0035] Specific implementation process and principle description:

[0036] When performing the press-fitting operation of the two bearings 200 at both ends of the workpiece 100, the feeding operation is carried out first. There are various forms of feeding. Generally, there is pre-assembly of the workpiece 100 and the two bearings 200, or the loading of the bearings 200, the workpiece 100, and the bearings 200 in sequence.

[0037] When pre-assembling the workpiece 100 and the two bearings 200, the turnover equipment will clamp the workpiece 100. At this time, the bushing ejector rod 32 of the pre-assembly lifting mechanism 3 will pre-position the bushing of the bearing 200, and then continue to rise to perform the pre-tightening operation after aligning the bearing 200 and the workpiece 100. The press-fitting carrier 4 will press down, and the bushing pressing rod 42 will pre-position the bushing of the top bearing 200, and then move downward to perform the guiding pre-pressing of the bearing 200 and the workpiece 100. At this time, the feeding equipment will retreat, and the press-fitting carrier 4 will move downward to perform the pressing operation, realizing the synchronous press-fitting assembly of the two bearings 200. After the assembly is completed, the external turnover equipment will pick up the materials and then perform the re-displacement and removal operation.

[0038] When feeding the workpiece 100 and the two bearings 200 separately, first, the bearing 200 is fed through the guiding of the bushing ejector rod 32. Then, after the workpiece 100 is transferred in place, the bearing carrier 31 is lifted to realize the guiding pre-pressing operation. After the pre-pressing is completed, the top bearing is loaded on the workpiece 100. At this time, the press-fitting carrier 4 moves downward, and the bushing pressing rod 42 positions and guides the bushing of the bearing. Then, the turnover equipment retreats, and the downward synchronous press-fitting assembly operation is carried out.

[0039] In a specific embodiment, the pre-assembly lifting mechanism 3 includes a lifting base 33 slidably arranged on the base body, at least one lifting drive source 34 arranged on the base device and drivingly connected to the lifting base, and the bearing carrier 31 and the bushing ejector rod are arranged on the lifting base.

[0040] That is, the lifting drive source 34 is used to realize the lifting drive of the lifting base 33, meeting the driving requirements for the synchronous lifting or lowering operations of the bearing carrier 31 and the bushing ejector rod.

[0041] In a specific embodiment, a press-fitting support mechanism 5 is arranged on the base body 10. There is a stroke interval 6 between the lifting base and the base body, and the press-fitting support mechanism has a support platform 50 for being embedded in or retreating from the stroke interval.

[0042] Driving parts 330 are respectively arranged on a group of opposite side walls of the lifting base, and a lifting drive source is arranged between any driving part and the base body.

[0043] Specifically, through the design of the stroke interval 6 and the support platform 50, after pre-lifting, the lifting base can be supported by the support platform 50 to meet the support and bearing requirements during the two-way crimping process. There is no need to perform resetting and re-crimping assembly operations after the pre-pressing of the lifting base, and the pressing efficiency is improved.

[0044] In addition, there is a certain stroke for the jacking preloading, and after the jacking preloading, a stroke interval 6 will be left. When the preloading jacking stroke is not in place, the support platform 50 cannot enter the stroke interval 6, and it can be determined that the preloading is not in place.

[0045] In a specific embodiment, the press-fitting support mechanism 5 includes a linear switching displacement driving source that is transmission-connected to the support platform, that is, the linear displacement driving of the support platform 50 is realized by the linear switching displacement driving source.

[0046] In a specific embodiment, the press-fitting frame 4 is provided with a press-fitting shaft seat 43 for carrying a bearing press-fitting seat and a bushing press-fitting rod, so as to meet the requirements of the mounting structure.

[0047] In a specific embodiment, the bushing jack 32 includes an elastic floating body disposed in the jacking base, and a bushing positioning core rod disposed in the bearing seat and abutting against the elastic floating body 320 .

[0048] A floating inner core which is elastically and floatingly connected to the bushing press-fitting rod is arranged in the press-fitting shaft seat 43 .

[0049] The floating inner core is located inside, so its illustration and number are omitted in the attached drawings. It only needs to meet the floating displacement of the bushing positioning core rod and the bushing crimping rod. All structures that meet its floating displacement are within the protection scope of this case.

[0050] In a specific embodiment, a locking and limiting mechanism 331 for locking or loosening the elastic floating body is provided on the jacking base 33; and a locking mechanism 430 for locking or loosening the floating inner core is provided on the press-fit shaft seat 43.

[0051] Specifically, during the pressing operation, the locking limit mechanism 331 and the locking mechanism 430 are in a released state, and when the two-way crimping is in place, the locking limit mechanism 331 and the locking mechanism 430 are locked separately, so that the elastic floating body and the floating inner core are locked. At this time, the bushing positioning core rod and the bushing crimping rod will not be ejected, and unloading can be carried out without a large separation gap. When the material is unloaded and loaded into place again, the locking limit mechanism 331 and the locking mechanism 430 release each rod body, and at this time, the elastic force is used to realize the pre-installed positioning and guiding of the bushing.

[0052] As can be seen from the above description, the vertical bearing two-way pressing equipment of the present utility model satisfies the two-way synchronous pressing operation. The synchronous pressing operation is efficient and smooth, and the pressing efficiency is significantly improved. It can realize the positioning and guiding of the bushing before pressing, ensuring the relative position accuracy of pressing and reliable and stable pressing quality. It has a support design for pressing, and the support reduces the downward stroke, further improving the pressing efficiency. At the same time, it also has a detection function for the pre-pressing stroke.

[0053] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, so that a process, method, article or equipment / device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent in these processes, methods, articles or equipment / devices.

[0054] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
