[0031] As Figure 1 , Figure 2 And Figure 4As shown, the inner wall of the second feeding opening 201 on both sides is inclined, specifically, it is inclined outward from bottom to top, so that the opening of the second feeding opening 201 is formed as an expanding opening, which facilitates the embedding of the bell-shaped shell 5, and simultaneously, based on the different diameters of the second feeding opening 201 at different height positions, the bracket of the utility model can also match the outer ball cage bell-shaped shell 5 of different external dimensions, thereby providing stable support.

[0032] As shown in Figure 1 , Figure 2 and Figure 4 , based on the changeable external dimensions of the bell-shaped shell 5, the diameter of the second feeding opening 201 on the front plate a1 of the rear plate body 2 is greater than that on the rear plate a1 of the rear plate body 2, that is to say, at the same height, the diameter of the second feeding opening 201 on the front plate a1 of the rear plate body 2 is greater than that on the rear plate a1 of the rear plate body 2, which makes the step position 204 on the front plate a1 of the rear plate body 2 match the part with a larger outer diameter of the bell-shaped shell 5, while the step position 204 on the rear plate a1 of the rear plate body 2 matches the part with a smaller outer diameter of the bell-shaped shell 5, that is, the part close to the tail shaft of the bell-shaped shell 5, thereby better limiting the displacement of the bell-shaped shell 5.

[0033] As shown in Figure 4 , the included angle between the inner wall of the second feeding opening 201 on both sides and the horizontal plane is 145°, which can ensure that the step position 204 stably supports the embedded bell-shaped shell 5, and at the same time, the inner wall on both sides of the second feeding opening 201 stably clamps the bell-shaped shell 5.

[0034] As shown in Figures 2 to 4 , the front plate body 1 is provided with an assembly guide groove 102 on one side, the assembly guide groove 102 penetrates the top and bottom of the front plate body 1, and the rear plate body 2 is slidingly matched in the assembly guide groove 102, and by controlling the movement of the rear plate body 2, the height of the rear plate body 2 relative to the front plate body 1 can be changed, thereby meeting the need of gear rolling processing of the bell-shaped shell 5 of different sizes.

[0035] As shown in Figures 2 to 4 , the assembly guide groove 102 is provided with a positioning guide groove 103, the positioning guide groove 103 is also a through groove structure, and the direction of the positioning guide groove 103 is consistent with that of the assembly guide groove 102, the rear plate body 2 is provided with a positioning hole 205 corresponding to the positioning guide groove 103, and the assembly guide groove 102 penetrates a positioning bolt 3, the positioning bolt 3 is threadedly connected with the positioning hole 205, and the head of the positioning bolt 3 abuts against the positioning guide groove 103 in the circumferential direction, so as to clamp the front panel 202 and the rear panel 203 relative to each other, and the rear panel 203 is kept at the adjusted height, when it is necessary to adjust again, the head of the positioning bolt 3 is rotated to be disengaged from the abutment against the front panel 202, at this time, the pressure applied by the head disappears, so that the rear panel 203 can be normally moved.

[0036] Further, the positioning guide groove 103 has two, and each positioning guide groove 103 corresponds to three positioning holes 205, the above-mentioned setting increases the height allowed to adjust the back plate 203, so that it can meet the more size clock shell 5 hobbing processing needs, it needs to be mentioned that, generally only through a positioning bolt 3 through the positioning guide groove 103 and corresponding one of the positioning hole 205 threaded connection, and by increasing the number of positioning bolt 3 can significantly improve the positioning effect of the back plate 203, thereby providing more stable support for the clock shell 5.
