[0039] As shown in Figure 1 , Figure 2 and Figure 3 , the irregular aluminum alloy box body 200 is arranged above the support column 5, the box body 200 can move vertically, so that the tapered bearing outer ring 100 can be press-fitted in the mounting groove of the box body 200. The present application discloses a tapered bearing outer ring universal press-fitting tool (hereinafter referred to as "tool"). The tool comprises a pressure head piece 1, a supporting seat 2, an adjusting assembly 3 and a fixing assembly 4, and is used for mounting the tapered bearing outer ring 100 on the support column 5, so as to realize the press-fitting with the mounting groove of the box body 200.

[0040] The upper end of the pressure head piece 1 is used to support the tapered bearing outer ring 100, and provides support for the tapered bearing outer ring 100. The lower end of the pressure head piece 1 is provided with a convex head part 11, which is a spherical protrusion. The upper end of the supporting seat 2 is provided with a groove part 21, and the upper end of the groove part 21 is provided with a spherical groove 211 with an upward opening. The spherical groove 211 is used to cooperate with the spherical protrusion, so that the pressure head piece 1 can be assembled above the supporting seat 2. Through the cooperation of the convex head part 11 of the spherical protrusion and the spherical groove 211 of the groove part 21, the relative deflection between the pressure head piece 1 and the supporting seat 2 can be realized, and the pressure head piece 1 can move freely in multiple directions, thereby realizing the universal alignment function, adjusting the relative position between the tapered bearing outer ring 100 supported by the upper end of the pressure head piece 1 and the mounting groove of the box body 200, and improving the alignment precision.

[0048] As Figure 1 , Figure 2 and Figure 3As shown, the axis of the connecting groove 13 coincides with the axis of the through hole 411 after the fixing member 41 is assembled with the pressure head member 1. The connecting groove 13 comprises a clamping portion 131 and a second through hole portion 132. The clamping portion 131 is arranged above the second through hole portion 132 along the axis direction of the connecting groove 13. The radial length of the clamping portion 131 is greater than the radial length of the second through hole portion 132. The radial length of the upper end of the fixing member 41 is greater than the radial length of the lower end of the fixing member 41. The clamping portion 131 cooperates with the upper end of the fixing member 41, and the second through hole portion 132 is used for penetrating the lower end of the fixing member 41, so that the fixing member 41 is clamped in the connecting groove 13. After the fixing member 41 is assembled with the pressure head member 1 in alignment, the upper end of the fixing member 41 is clamped by the clamping portion 131 of the connecting groove 13, and the second through hole portion 132 of the connecting groove 13 is used for penetrating the lower end of the fixing member 41, so that the fixing member 41 is erected on the pressure head member 1. The axis of the connecting groove 13 coincides with the axis of the through hole 411, which helps to accurately align the fixing member 41 with the pressure head member 1 and improves the reliability of assembly. The diameters of the second through hole portion 132 and the limiting hole 24 can be equal to the diameter of the lower end of the fixing member 41. It can be understood that in the embodiment, the axis direction of each structure, groove and hole is the X direction, and the radial direction is the Y direction perpendicular to the X direction in the plane.

[0049] The diameter of the first through hole portion 25 is smaller than the diameter of the limiting hole 24, so that the lower end of the fixing member 41 can abut against the lower end of the limiting hole 24 to limit the fixing member 41. After the convex head portion 11 cooperates with the spherical groove 211, the minimum distance between the bottom of the clamping portion 131 and the lower end surface of the limiting hole 24 along the axis direction of the connecting groove 13 is smaller than the length of the lower end of the fixing member 41, so that after the fixing assembly 4 connects the support column 5, the pressure head member 1 and the supporting seat 2 can have a vertical position adjustment along the axis direction, so that the adjusting assembly 3 can realize the elastic support function, and at the same time, when the tapered bearing outer ring 100 is press-fitted in the mounting groove of the box body 200, the automatic correction of the tapered bearing outer ring 100 can be realized by the relative movement of the pressure head member 1 relative to the supporting seat 2, so that the tapered bearing outer ring 100 can be aligned with the mounting groove and accurately press-fitted, and the damage to the box body 200 is reduced.

[0050] As Figure 1 , Figure 2 and Figure 3As shown, the fastener 42 is a bolt. The use of a bolt for the fastener 42 can effectively improve the stability and reliability of the device, so that the connection between the components is more secure during the press-fitting process, preventing loosening or falling off, so that the press-fitting can be smoothly carried out; at the same time, the use of a bolt is convenient for disassembly and maintenance, and can improve the operability of the device. In use, the pressure head piece 1 is fixed on the bearing seat 2 by a bolt, and the convex head part 11 with a spherical convex is matched with the spherical groove 211 of the groove part 21, so that the pressure head piece 1 is in spherical contact with the bearing seat 2, and is supported by the disc spring 31 and the adjusting washer 32. During the press-fitting process, when the tapered bearing outer ring 100 contacts the box body 200 instantaneously, the disc spring 31 is compressed, and the spherical surface of the pressure head piece 1 and the bearing seat 2 is in close contact, so that the universal alignment can be carried out. The adjusting washer 32 adjusts the pressure at the moment when the tapered bearing outer ring 100 contacts the box body 200, so that the spherical surface of the pressure head piece 1 and the bearing seat 2 can be in contact in time to realize the alignment adjustment, so that the tapered bearing outer ring 100 can be smoothly pressed into the box body 200, and the risk of the tapered bearing outer ring 100 being inclined after press-fitting and the box body 200 being scratched due to the manufacturing and processing errors of the tooling is reduced.

[0051] Optionally, after the convex head part 11 is connected with the spherical groove 211, the upper end surface of the fastener 42 is lower than the upper end surface of the pressure head piece 1 along the axis direction of the connecting groove 13, which can reduce the risk of interference or damage to the tapered bearing outer ring 100 caused by the fastener 42 during the press-fitting process, and improve the stability and reliability of the press-fitting. At the same time, the tooling can be more compact, reducing the space occupation and improving the operation convenience.

[0052] As shown in FIG. 1, the pressure head piece 1 is connected with the bearing seat 2 through the connecting groove 13, and the connecting groove 13 is provided with a fastener 42. Figure 1 、 Figure 2 and Figure 3As shown, the box body 200 is matched with the supporting column 5 and moves relatively by a connecting mechanism, which comprises a sliding sleeve 300, a suspension base plate 400, a supporting frame 500 and a connecting frame 600, and the supporting column 5 and the connecting mechanism are both provided with a machine body (not shown in the figure). The supporting column 5 is sleeved with the sliding sleeve 300, the sliding sleeve 300 is connected with the suspension base plate 400 through the connecting frame 600, the suspension base plate 400 is connected with the supporting frame 500, and the supporting frame 500 is used for supporting the box body 200, so that the box body 200 can be assembled and connected with the supporting frame 500. When the tool is used, the cone bearing outer ring 100 is placed on the pressure head piece 1, the box body 200 is arranged on the supporting frame 500, the mounting groove of the box body 200 is located directly above the supporting column 5, the box body 200 is driven to move downward by the sliding sleeve 300 relative to the supporting column 5, so that the press-fitting between the cone bearing outer ring 100 and the box body 200 can be realized, then the sliding sleeve 300 is moved upward to reset, and one press-fitting process is completed. Since the connecting mechanism and the machine body are both prior arts, the specific structure and the implementation principle will not be described in detail here, and the existing structure can be selected according to the need. It can be understood that the tool also comprises necessary structures for connection, support, driving, positioning, limiting, control and the like, so that the tool can normally operate; the shape, size, material and setting number and the like of each part of the tool can be determined according to the need, and the corresponding function can be realized.

[0053] The implementation principle of the universal pressing tool for the outer ring of the tapered bearing is as follows: the upper end of the pressing head 1 supports the outer ring 100 of the tapered bearing, the protruding head part 11 at the lower end of the pressing head 1 is matched with the protruding groove part 21 at the upper end of the supporting seat 2, so that the pressing head 1 is arranged above the supporting seat 2, and the relative deflection between the pressing head 1 and the supporting seat 2 can be realized through the matching of the spherical protruding head part 11 and the spherical groove 211 of the groove part 21, the pressing head 1 can freely move in multiple directions, thereby realizing the universal alignment function, adjusting the relative position between the outer ring 100 of the tapered bearing supported by the upper end of the pressing head 1 and the mounting groove of the box 200 above the supporting column 5, and improving the alignment and fitting accuracy; since the adjusting assembly 3 is arranged between the pressing head 1 and the supporting seat 2, the adjusting assembly 3 can expand the pressing head 1 and the supporting seat 2 through the elasticity of the adjusting assembly 3, reduces the uneven distribution of the pressing force, so that after the fixing assembly 4 fixes the pressing head 1 and the supporting seat 2 on the supporting column 5, the adjusting assembly 3 can make the pressing head 1 and the supporting seat 2 have a vertical adjustment allowance, in combination with the deflection caused by the spherical surface matching between the spherical protruding head part 11 and the spherical groove 211 of the groove part 21, so that when the outer ring 100 of the tapered bearing above the pressing head 1 is inclined, the automatic correction and adjustment of the outer ring 100 of the tapered bearing can be realized through the relative movement of the pressing head 1 relative to the supporting seat 2 when the outer ring 100 of the tapered bearing is pressed with the mounting groove of the box 200, the alignment and fitting accuracy between the outer ring 100 of the tapered bearing and the mounting groove of the box 200 is improved, the tool can be applied to the irregularly shaped box 200, and the risk of damaging the box 200 is reduced.

[0054] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
