[0001] This utility model relates to the field of nylon cage manufacturing, and specifically to a tooling for manually pressing nylon cages. Background Technology
[0002] In the field of mechanical assembly, the manual press-fitting process for nylon cages presents a significant technical bottleneck. This component is mostly used in low- and medium-speed bearing systems, and its outer diameter is designed with an interference fit allowance (usually controlled within the range of 0.05-0.15mm) between it and the housing.
[0003] In existing technologies, when manually pressing nylon cages, the nylon cage's plane is lower than the bearing product's plane, which can lead to situations where the nylon cage is not pressed into place during the pressing process. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a tooling for manually pressing nylon cages.
[0005] To achieve the objective of this utility model, the technical solution adopted is as follows:

[0012] After the workpiece to be pressed is placed in place, the pressing machine applies downward force to press it in, so that the horizontal plane of the pressing machine contact ring is lower than the horizontal plane of the platform on the upper surface of the pressing ring. After pressing is completed, the horizontal plane of the pressing machine contact ring is restored to the horizontal plane of the platform on the upper surface of the pressing ring under the action of the elastic element.
[0013] In a preferred embodiment of this utility model, the press machine contact ring is provided with a limiting ring for limiting the operation of the press machine.
[0014] In a preferred embodiment of this utility model, the workpiece to be pressed is a nylon retainer.

[0024] In order to solve the defect in the prior art where the plane of the nylon cage 10 is lower than the plane of the bearing product 1, the nylon cage may not be properly pressed in during the pressing process.
[0025] This utility model discloses, as follows: Figure 1-3The image shows a tooling for manually pressing nylon retainers.
[0026] It includes a tooling body, and a support ring 100 is provided at the lower part of the tooling body for supporting the lower part.
[0027] A pressing ring 200 is provided in the middle of the support ring 100, which contacts the pressing lower end face 11 of the workpiece 10 to be pressed. The workpiece to be pressed is a nylon retainer. The pressing ring 200 contacts the pressing lower end face 11 of the workpiece 10 mainly through the platform of the upper surface 210 of the pressing ring 200.
[0028] A press-fitting machine contact ring 300 is provided on the outer side of the platform of the upper surface 210 of the press-fitting ring 200, which contacts the lower end face 21 of the external press-fitting machine. A plurality of elastic elements 400 are provided between the support ring 100 and the press-fitting machine contact ring 300. In this embodiment, the elastic element 400 is a spring.
[0029] The upper end of the elastic element 400 contacts the first elastic element 301 mounting part on the lower surface of the press-fitting machine contact ring 300, and the lower end of the elastic element 400 contacts the second elastic element mounting part 101 on the upper surface of the support ring 100.
[0030] Will as Figure 3 After the workpiece 10 and bearing 1 are placed in position, an external pressing machine (not shown in the figure) is used. This commercial pressing machine primarily functions to apply downward force during the pressing operation.
[0031] The pressing operation applies downward force so that the horizontal plane of the pressing machine contact ring 300 is lower than the horizontal plane of the platform of the upper surface 210 of the pressing ring 200.
[0032] After pressing is completed, the horizontal height of the contact ring 300 of the pressing machine is restored to the horizontal height of the platform of the upper surface 210 of the pressing ring 200 under the action of the elastic element 400.
[0033] To ensure proper pressing, the press-fitting machine contact ring 300 is equipped with a limit ring 500 to limit the operation of external press-fitting machines. The limit ring 500 can be set to an arc shape or a semi-circle according to actual needs.
[0034] Because of the above structure, the working principle of this utility model is as follows:
[0035] After placing the workpiece 10 to be pressed onto the platform on the upper surface 210 of the pressing ring 200,
[0036] The pressing operation is performed by applying downward force through an external pressing machine, so that the horizontal plane of the pressing machine contact ring 300 is lower than the horizontal plane of the platform of the upper surface 210 of the pressing ring 200.
[0037] At this point, the pressing of the workpiece 10 to be pressed is completed when it is fully inserted into the cage mounting cavity of the bearing 1.
[0038] After the pressing is completed, the bearing 1, which holds the workpiece 10 to be pressed, is removed from the platform on the upper surface 210 of the pressing ring 200.
[0039] Furthermore, the external press machine also moves away from the horizontal plane of the press machine contact ring 300.
[0040] Under the action of the elastic element 400, the horizontal height of the contact ring 300 of the press machine is restored to the horizontal height of the platform of the upper surface 210 of the press ring 200.
[0041] This invention ensures that the nylon cage of the bearing is properly pressed in place during the pressing process, thus guaranteeing a qualified pressing process.
[0042] The above shows and describes the basic principles, main features, and advantages of this utility model.
[0043] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of this utility model as defined by the appended claims and their equivalents.
