[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] The utility model provides a press-fitting device for assembling a bearing ring, such as Figures 1 to 3 As shown, it includes a base body 1, on which a support guide floating mechanism 2 and a bearing pressing mechanism 3 arranged on the top of the support guide floating mechanism are provided.

[0033] The supporting guide floating mechanism 2 comprises a supporting pile sleeve 4 with a hollow channel 40, a supporting ring sleeve 5 arranged at the top of the supporting pile sleeve 4, and a floating lifting part 6 arranged in the hollow channel. The floating lifting part is provided with an assembly guide body 7 penetrating the supporting ring sleeve 5.

[0034] The bearing crimping mechanism 3 comprises a lifting power source 8 , which has a lifting drive end vertically facing the supporting pile sleeve, and an assembly crimping body 9 is provided on the lifting drive end.

[0035] Specific implementation process and principle description:

[0036] When assembling the bearing and the trap, the support ring sleeve 5 on the support pile sleeve 4 is used to achieve limited support for the carrier, and the floating jacking of the assembly guide body 7 is used to achieve auxiliary floating positioning of the bearing or the trap. When performing the crimping operation, the lifting power source 8 drives the assembly crimping body 9 to press down, thereby achieving the assembly and connection of the bearing and the trap.

[0037] In a specific embodiment, a guide platen 10 and a plurality of guide columns 11 penetrating the guide platen are provided on the base body 1, a power source carrier 12 for carrying a lifting power source is provided at the top of the plurality of guide columns 11, the lifting drive end is transmission-connected with the guide platen, and an assembly pile 13 for carrying an assembled crimping body is provided at the bottom of the guide platen.

[0038] Specifically, during the crimping process, the crimping force is relatively large. In order to meet the crimping concentricity stability requirements, the guiding function of the guide pressure plate 10 is used to ensure that the crimping stroke is accurate and reliable.

[0039] In a specific embodiment, the assembly pile 13 is detachably disposed on the guide pressure plate 10, and the assembly crimping body is detachably disposed on the assembly pile.

[0040] Specifically, bearings and rings have differentiated specifications, and assembly piles are prone to damage after long-term use, so the replaceable structure is conducive to changing models and repairing and replacing accessories.

[0041] It should be noted that the assembly pile 13 can be assembled and disassembled by T-bolts by setting a T-slot on the guide pressure plate 10, and the assembly crimping body 9 can be radially bolted by setting an annular recess on the assembly pile 13. Of course, structures such as screw connection, snap assembly, and pin assembly can also be used. It only needs to meet the detachable matching structure between the assembly pile 13 and the guide pressure plate 10 and between the assembly crimping body and the assembly pile, which are all within the protection scope of this case.

[0042] In a specific embodiment, a support base plate 14 for carrying a plurality of guide columns is provided on the base body 1, and the support pile sleeves 4 are detachably arranged on the support base plate.

[0043] Specifically, by supporting the base plate 14 so that it forms an integral structure with the guide column, the crimping alignment structure is more solid and the stroke is more precise.

[0044] In a specific embodiment, the support ring sleeve 5 is detachably arranged on the support pile sleeve.

[0045] Specifically, there are many specifications of bearings and rings, and various specifications can be replaced by replacing the support pile sleeve and the support ring sleeve 5. The replacement structure generally adopts radial bolts or axial bolts, and the replacement is efficient and smooth.

[0046] For the differential assembly of the bearing with the inner ring and the outer ring, the assembly crimping body 9 is a crimping tube sleeve body 91 or a crimping shaft 92 with a centering positioning protrusion. The assembly guide body 7 is an auxiliary positioning shaft rod 71 or a liner positioning tube sleeve 72.

[0053] Embodiment 4

[0054] like Figure 7 As shown, it is a secondary connection between the bearing and the inner ring shaft, the assembly crimping body 9 is a crimping tube sleeve body 91, and the assembly guide body 7 is an inner liner positioning tube sleeve 72.

[0055] Therefore, the press-fitting device of the present invention can meet any assembly and matching requirements of the secondary matching of the bearing and the outer ring sleeve of the sprocket gear set, the bearing and the outer ring sleeve, the bearing and the inner ring shaft rod, and the bearing and the inner ring shaft rod.

[0056] In addition, embodiments 1 to 4 are four assembly stations of a bearing ring. The press-fitting device of this case can meet any type change of the four assembly stations of the bearing ring and meet its assembly and crimping requirements.

[0057] From the above description, it can be found that the press-fitting device for the assembly of the bearing ring of the utility model can realize floating support and crimping, meet the guide support requirements during the crimping process, and reduce the scrap rate. It has a precise crimping guide design, so that the crimping concentricity is reliably guaranteed and the product qualification rate is significantly improved. The detachable design of the assembly pile, assembly crimping body, support pile sleeve, and support ring sleeve meets the equipment changeover requirements and is suitable for the crimping assembly requirements of various bearing rings. It is particularly suitable for step-by-step molding crimping bearing products, and can meet the crimping changeover requirements of each step.
