The diameter of the first bearing hole is, for example, 230 mm. The first bearing hole runs through the first side surface and the second side surface. A first threaded hole group is provided on the first side surface, for example, including 4×M16 threaded holes; a second threaded hole group is provided on the second side surface, for example, including 4×M16 threaded holes. In addition, the first shaft box 1 is also provided with a first joint hole. The diameter of the first joint hole is, for example, 190 mm.

[0038] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0039] See also Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model provides a shaft box multi-process universal tool 10. The shaft box multi-process universal tool 10 is used to clamp the first shaft box 1 (also called A-type shaft box) for processing the first shaft box 1. The shaft box multi-process universal tool 10 includes, for example: a tool base 100, a bearing hole positioning member 200, an auxiliary support mechanism 300, a first clamping mechanism 400, a second clamping mechanism 500, and a third clamping mechanism 600.

[0040] Specifically, the tool base 100 is used, for example, to provide support and installation positions for other parts of the axle box multi-process universal tool 10. The tool base 100, for example, has a mounting table 101. The mounting table 101 is, for example, the upper plane of the tool base 100. The bearing hole positioning member 200 is arranged on the mounting table 101. The bearing hole positioning member 200 has a positioning portion 201, which is used to position the first bearing hole of the first axle box 1 to define two degrees of freedom in the diameter direction of the first bearing hole and the free end of the axial direction of the first bearing hole. The auxiliary support mechanism 300 is arranged on the mounting table 101 and is arranged opposite to the bearing hole positioning member 200. That is, the auxiliary support mechanism 300 and the bearing hole positioning member 200 are arranged at opposite ends of the mounting table 101. The auxiliary support mechanism 300 has a support portion 301. The support portion 301 is used to auxiliary support one end of the first shaft housing 1 adjacent to the first joint hole, so as to jointly limit the degree of freedom of the first bearing hole on the first shaft housing 1 in the axial direction with the bearing hole positioning member 200 .

[0041] Based on the above, Figure 4As shown, the first clamping mechanism 400 is disposed on the mounting table 101 and is located on a side of the auxiliary support mechanism 300 away from the bearing hole positioning member 200. The second clamping mechanism 500 is disposed on the mounting table 101 and is located on a first side of a center line CC between the center of the support portion 301 and the center of the positioning portion 201, such as Figure 4 The third clamping mechanism 600 is disposed on the mounting table 101 and is located on a second side of the center line CC opposite to the first side, such as Figure 4 That is, the first clamping mechanism 400, the second clamping mechanism 500 and the third clamping mechanism 600 are arranged in a triangular shape, and are respectively clamped at positions other than the first bearing hole, the first joint hole, the first threaded hole group and the second threaded hole group on the first shaft housing 1, so as to effectively clamp the first shaft housing 1.

[0042] When using the axle box multi-process universal tooling 10 provided by the utility model, the user first places one side surface of the first axle box 1, for example, the second side surface, against the positioning portion 201 of the bearing hole positioning member 200, and extends the positioning portion 201 into the first bearing hole, and supports the other end of the first axle box 1 on the supporting portion 301 of the auxiliary supporting mechanism 300, and then uses the first clamping mechanism 400, the second clamping mechanism 500 and the third clamping mechanism 600 to clamp the first axle box 1 to complete the first clamping (see Figure 5 ). After that, the user can complete the drilling and tapping process of the first threaded hole group. Next, remove the first shaft box 1 and turn it over to complete the second clamping of the first shaft box 1 using the same clamping method (see Figure 6 ). After that, the user can complete the drilling and tapping process of the second threaded hole group, the fine boring process of the first bearing hole, and the fine boring process of the first joint hole, that is, the processing of the first shaft box 1 is completed.

[0043] In this way, when the user uses the axle box multi-process universal tooling 10 provided by the utility model, through the bearing hole positioning member 200, the auxiliary support mechanism 300, and multiple clamping mechanisms with a specific relative position relationship, the user only needs to complete the processing of the first axle box 1 through two clampings, thereby improving the processing accuracy of the first axle box, while also reducing the number of tooling, thereby reducing the processing cost of the first axle box 1.

[0044] In addition, if Figure 7 As shown, the bearing hole positioning member 200 is a columnar positioning member, one end of which (for example Figure 7 The lower end of the middle bearing hole positioning member 200 is connected to the mounting table 101, and the positioning portion 201 is arranged at the other end of the columnar positioning member (for example Figure 7The upper end of the middle bearing hole positioning member 200). The positioning portion 201 is, for example, a positioning stop. Further, the positioning portion 201 includes, for example, a positioning plane 2011 and a circular positioning protrusion 2012. The positioning plane 2011 and the circular positioning protrusion 2012 are arranged on the other end of the columnar positioning member. The circular positioning protrusion 2012 protrudes from the positioning plane 2011 and extends in a direction away from the mounting table 101. The positioning plane 2011 is arranged around the circular positioning protrusion 2012, so that the circular positioning protrusion 2012 can better extend into the first bearing hole.

[0045] In addition, if Figure 3 As shown, the auxiliary support mechanism 300 is a linear reciprocating telescopic mechanism, such as an oil cylinder, a pneumatic cylinder, etc. The support portion 301 is located at one end of the auxiliary support mechanism 300 away from the mounting table 101, and the support portion 301 can move relative to the mounting table 101 in a direction away from or close to the mounting table 101. With such a configuration, the user can adjust the height position of the support portion 301 according to the actual clamped shaft box to assist in supporting the shaft box, so that the shaft box multi-process universal tooling 10 can be applied to more series of products of different sizes.

[0046] In a specific embodiment of the present invention, the first clamping mechanism 400 is a first automatic clamping mechanism. Furthermore, the second clamping mechanism 500 and the third clamping mechanism 600 are also automatic clamping mechanisms. That is, through user control operation, the first clamping mechanism 400, the second clamping mechanism 500 and the third clamping mechanism 600 can automatically complete the clamping or loosening of the first shaft box 1, thereby realizing the automatic clamping of the workpiece, reducing the clamping workload and improving the clamping efficiency. Specifically, Figure 8 As shown, the first automatic clamping mechanism includes: a base 410, a rotating oil cylinder 420 and a clamping member 430. Specifically, the base 410 is disposed on the mounting table 101. One end of the rotating oil cylinder 420 is disposed on the base 410. The clamping member 430 is connected to the other end of the rotating oil cylinder 420 and can rotate relative to the tooling base 100 and move along the axis direction of the rotating oil cylinder 420 under the drive of the rotating oil cylinder 420. Figure 8As shown, the clamping member 430 can rotate an angle θ under the drive of the rotating cylinder 420. The angle θ is, for example, 90 degrees, 180 degrees, etc., and of course it can also be other angles, and the utility model is not limited to this. The range of movement of the clamping member 430 along the axial direction of the rotating cylinder 420 can be determined according to the size of the axle box to be clamped by the axle box multi-process universal tooling 10. The base 410 is, for example, a rectangular block-shaped component. The rotating cylinder 420 is, for example, a hydraulic rotating cylinder, which typically has a rod chamber and a rodless chamber, and includes a piston and a cylinder body. When the hydraulic oil enters the rodless chamber of the rotating cylinder, the piston moves linearly along the cylinder body under the push of the hydraulic oil, and at the same time drives the piston rod to rotate, thereby realizing rotational motion and linear motion at the same time. The clamping member 430 is, for example, a plate-shaped component.

[0047] More specifically, if Figure 8 As shown, the clamping member 430 is provided with a clamping portion 431, and the clamping portion 431 is located at one end of the clamping member 430 away from the rotating oil cylinder 420. When the clamping member 430 is in a clamping state, the clamping portion 431 is opposite to the supporting portion 301. The clamping state here refers to the state when the first clamping mechanism 400 clamps the first shaft box 1. The clamping portion 431 is arranged opposite to the supporting portion 301, so that the first clamping mechanism 400 can better clamp the first shaft box 1.

[0048] In other embodiments of the present invention, Fig. 9 As shown, the axle box multi-process universal tooling 10 also includes a joint hole positioning mechanism 700. The joint hole positioning mechanism 700 is arranged on the mounting table 101 and is located between the auxiliary support mechanism 300 and the bearing hole positioning member 200. The joint hole positioning mechanism 700 is used to position the first joint hole of the first axle box 1 to limit the rotational freedom of the first axle box 1, so as to better clamp and position the first axle box 1. Specifically, the joint hole positioning mechanism 700 is, for example, a double-jaw chuck; the double-jaw chuck is connected to the tooling base 100. The double-jaw chuck can specifically be a double-jaw hydraulic chuck or a double-jaw pneumatic chuck. The double-jaw chuck extends into the first joint hole, and the two jaws of the double-jaw chuck extend outward and abut against the inner side of the first joint hole, thereby realizing the positioning of the first joint hole.

[0049] Furthermore, if Fig.10 , Fig.11 and Fig.12As shown, the shaft box multi-process universal tooling 10 also includes a lifting mechanism 800 and a guide mechanism 900. The double-jaw chuck is connected to the tooling base 100 through the lifting mechanism 800. Wherein, a guide hole 1011 is provided on the mounting table 101. The guide mechanism 900 includes a connecting member 910 and a guide rod 920. The connecting member 910 is connected between the lifting mechanism 800 and the double-jaw chuck. The double-jaw chuck can reciprocate relative to the tooling base 100 under the drive of the lifting structure 800; the guide rod 920 is connected to the connecting member 910 and inserted into the guide hole 1011. The lifting mechanism 800 is, for example, a linear telescopic reciprocating motion mechanism, such as an oil cylinder, a pneumatic cylinder, and the like. The connecting member 910 is, for example, a plate-shaped part. The guide rod 920 is, for example, a rod-shaped part. One end of the guide rod 920 is connected to the side of the connecting member 910 away from the double-jaw chuck. When it is necessary to clamp and position the first shaft box 1 with different height dimensions, it is necessary to adjust the lifting mechanism 800 to drive the guide mechanism 900 and the joint hole positioning mechanism 700 to move up and down to a suitable position, and then control the joint hole positioning mechanism 700 to complete the positioning of the first joint hole. During the lifting process, the guide mechanism 900 is used to guide the lifting mechanism 800 to ensure that the lifting mechanism 800 does not deviate and ensure that the joint hole positioning mechanism 700 can be stable and move in the up and down direction.

[0050] Therefore, the working process of the axle box multi-process universal tooling 10 provided by the utility model includes, for example, the following steps.

[0051] 1. Control the various rotary cylinders of the multi-process universal tooling 10 of the shaft box to be in a loose state, turn the angle to a position away from the first shaft box 1, and control the double-claw chuck of the joint hole positioning mechanism 700 to be in a retracted state;

[0052] 2. Hoist the first axle box 1 onto the axle box multi-process universal tooling 10, position one end side surface of the first bearing hole on the positioning portion 201, control the double-claw chuck of the joint hole positioning mechanism 700 to open, and position the first joint hole.

[0053] 3. Control the rotating cylinder to move toward the first shaft box 1 , and at the same time control the auxiliary supporting cylinder to support the first shaft box 1 and clamp the first shaft box 1 .

[0054] 4. Control the claws of the double-claw chuck of the joint hole positioning mechanism 700 to retract, and control the lifting mechanism 700 to descend, so that the double-claw chuck of the joint hole positioning mechanism 700 is away from the bottom of the hole to be processed.

[0055] 5. Start the machining center and begin machining the first axis box 1.

[0056] Furthermore, if Fig.10 and Fig.12 As shown, the tooling base 100 includes, for example, a top plate 110, a bottom plate 120 and a connecting plate 130. Specifically, the top plate 110 and the bottom plate 120 are arranged relative to each other, such as in parallel. A plurality of connecting plates 130 are respectively connected between the top plate 110 and the bottom plate 120. In this way, an accommodating space is formed between the top plate 110 and the bottom plate 120. Among them, the mounting table 101 is the side of the top plate 110 away from the bottom plate 120; the lifting mechanism 800 is connected to a side of the top plate 110 away from the mounting table 101 and is located between the top plate 110 and the bottom plate 120. The lifting mechanism 800 passes through the top plate 110 and is connected to a side of the connecting member 910 away from the double-jaw chuck.

[0057] In addition, if Fig.13a and 13b As shown, the subway vehicle also includes a second axle box 2 (also called a B-type axle box). The second axle box 2 has a similar basic structure to the first axle box 1, and its outer dimensions are larger than those of the first axle box 1. Specifically, the second axle box 2 has a third side and a fourth side that are arranged opposite to each other, and the second axle box 2 has a second bearing hole. The diameter of the second bearing hole is the same as the diameter of the first bearing hole. The second bearing hole runs through the third side and the fourth side. A third threaded hole group is provided on the third side, for example, including 4×M16 threaded holes, which is the same as the first threaded hole group; a fourth threaded hole group is provided on the fourth side, for example, including 4×M16 threaded holes, which is the same as the second threaded hole group. The second axle box 2 is also provided with a second joint hole. The diameter of the second joint hole is the same as the diameter of the first joint hole. Therefore, the processing technology of the second axle box 2 is the same as that of the first axle box 1. However, due to some differences in the outer structure, the processing of the second axle box 2 needs to be completed using another tooling, so there is a problem that the tooling is not universal with the first axle box 1, resulting in a high processing cost.

[0058] In order to solve the problem of high processing costs caused by the non-universality of tooling, such as Fig.14 As shown, the axle box multi-process universal tooling 10 of the utility model may also include: a fourth clamping mechanism 1100 and a fifth clamping mechanism 1200. Specifically, the fourth clamping mechanism 1100 is arranged on the mounting table 101 and is located on the first side of the center line CC, and the fourth clamping mechanism 1100 is also located on the side of the second clamping mechanism 500 away from the first clamping mechanism 400. The fifth clamping mechanism 1200 is arranged on the mounting table 101 and is located on the second side of the center line CC, and the fifth clamping mechanism 1200 is also located on the side of the third clamping mechanism 600 away from the first clamping mechanism 400.

[0059] Among them, Fig.15 and Fig.16As shown, the fourth clamping mechanism 1100, the fifth clamping mechanism 1200 and the first clamping mechanism 400 are used to clamp the second shaft box 2 together. The clamping method and processing method of the second shaft box 2 are similar to those of the first shaft box 1, and will not be repeated here. In this way, the shaft box multi-process universal tooling 10 provided in the embodiment of the utility model can be adapted to the first shaft box 1 and the second shaft box 2, realizing the clamping and processing of various types of shaft boxes, realizing the universality and utilization of tooling, and reducing costs.
