[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings:

[0023] A cage tooling 2, such as Figures 1-3 The device includes a base 29, on the upper side of the work station of the base 29, a retaining boss 24 is provided, and retaining grooves 21 are provided on both sides of the retaining boss 24; the retaining boss 24 matches the inner groove 11 in the middle of the retainer 1, and the retaining grooves 21 match the outer grooves 12 on both sides of the retainer 1; a first positioning member 23 that cooperates with the retainer 1 is provided on one side wall of the retaining groove 21.

[0024] The inner and outer grooves of the retainer 2 are positioned on the base 29 by two retaining grooves 21 and one retaining boss 24, which facilitates quick positioning and installation, improves processing efficiency, and reduces processing cycle.

[0025] like Figure 2A reference surface 22 is provided on the other side wall of the retaining groove 21. The reference surface 22 and the positioning element facilitate rapid processing of the retainer after installation.

[0026] More specifically, a plurality of first positioning elements 23 are spaced apart on one side wall of the retaining groove 21. A second positioning element 28 is provided on the retaining boss 24 to cooperate with the inner groove 11. The arrangement of multiple positioning elements improves the accuracy of positioning and installation.

[0027] like Figure 1 The retaining boss 24 is provided with a detachable pressure plate 25, which detachably mounts the retainer 1 onto the retaining boss 24. Figure 2 Part of the pressure plate 25 was removed. After installing the retainer, the retainer 1 is installed / fixed to the base of the tooling 2 using bolts 26 and pressure plate 25. One end of the pressure plate 25 is provided with a U-shaped groove, which can adjust the installation position of the pressure plate and also enable quick removal and placement of the retainer 1. For example, after loosening the bolt 26, the pressure plate 25 can be pulled out using the U-shaped groove. After installing the retainer 1, the U-shaped groove of the pressure plate 25 is inserted into the bolt 26 through the U-shaped groove. After adjusting the position, the bolt is tightened to achieve quick installation and removal of the retainer.

[0028] Figure 1 and Figure 2 In this design, two workstations are spaced apart on the base 29; an installation direction indicator 27 for the retainer 1 is provided on the upper side of the base 29. Two retainers 1 can be installed and processed at the same time, and the installation direction indicator 27 specifies the installation direction of the retainer. More specifically, the retainers 1 at the two workstations are installed in opposite directions.

[0029] Figure 3 The structure of the cage 1 is schematically shown, including an inner groove 11 and two outer grooves 12.

[0030] The cage tooling of this utility model can be made of metal parts. In one specific embodiment, carbon structural steel is used, but it is not limited thereto.

[0031] The retainer fixture 2 of this utility model can quickly install or remove the retainer 1, and can adjust part of the processing surface. By setting the positioning part, part of the surface to be processed can be adjusted to the vertical direction.

[0032] The cage tooling 2 of this utility model can process radial cages or axial cages of three-row roller slewing bearings. The shapes of radial cages and axial cages are slightly different. The arrangement of the first positioning element and the second positioning element, as well as the height of the reference surface, can be adjusted according to the actual product structure.
