[0031] In order to make the purpose, technical solutions and advantages of this application clearer, the following will be combined with the attached Figure 1-6 The present application is further described in detail. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0033] First, in order to facilitate understanding of an active bevel gear auxiliary tooling provided in this embodiment, the following explanation is made: the active bevel gear 4 is a high-precision part on the vehicle reducer, especially the thrust washer slot 6 on the stepped shaft 5 of the active bevel gear 4 is of paramount importance; wherein, the thrust washer slot 6 is an arcuate slot structure. In the prior art, manual marking is used for milling through double center positioning, but the defects are also obvious. In the case of manual intervention, there are certain human factors. Once a mistake occurs, the product will be scrapped. Secondly, due to the lack of corresponding support for double center positioning, during the milling process, the overall stability of the stepped shaft 5 is poor, and there will be certain errors, which affects the overall accuracy of the thrust washer slot 6. Moreover, only one part can be processed at a time, which is inefficient and time-consuming.

[0034] It needs to be further explained that the stepped shaft is arranged in the middle of one end of the active bevel gear 4, and a thrust washer slot 6 to be processed is arranged on one side of the free end of the stepped shaft 5, and the center of the thrust washer slot 6 is at the same height as the center of the stepped shaft 5.

[0035] The present application provides an auxiliary tooling for an active bevel gear 4, comprising: a fixed disk 1, with a plurality of supporting and clamping structures 3 evenly arranged in the middle along the outer edge of a virtual circle 2; an active bevel gear 4 is fixed on each of the supporting and clamping structures 3; the supporting and clamping structures 3 comprise: two flexible supporting plates 31 arranged in parallel at the upper end of the fixed disk 1, and two supporting blocks 32 arranged horizontally on both sides of the upper ends of the two flexible supporting plates 31; wherein, a stepped shaft 5 on one side of the active bevel gear 4 is connected to the upper ends of the two supporting blocks 32 and fixed by a pressing plate 33; a thrust washer slot 6 to be processed is provided on the outer surface of one side of the part where the end of the step away from the active bevel gear 4 extends into the virtual circle 2.

[0036] In this embodiment, six groups of supporting clamping structures 3 are arranged on the outer edge of the virtual circle 2; in actual working conditions, the size of the fixed plate 1 can be adapted to the size of the claws of the vertical lathe, which will not be explained in detail here.

[0037] It can be understood that an active bevel gear 4 is fixed on each supporting clamping structure 3, and the angle between the axis of each active bevel gear 4 and the tangent line of the virtual circle 2 is the same; when in use, the thrust washer slots 6 of six stepped shafts 5 can be processed at one time through the tool arranged vertically at the bottom of the lathe spindle, which is efficient, precise, time-saving and labor-saving.

[0038] Optionally, a clamping hole 10 for clamping and fixing with a lathe claw is provided in the middle of the fixed plate 1; the clamping hole 10 is concentric with the virtual circle 2, and the diameter of the clamping hole 10 is smaller than the virtual circle 2; the fixed plate 1 is provided with locking screw holes 11 arranged in an annular array along the periphery of the clamping hole 10.

[0039] It can be understood that the locking screw holes 11 arranged in a circular array on the fixing plate 1 facilitate adjustment of the installation position of the supporting clamping structure 3; the fixing plate 1 is designed as a circular structure to facilitate the installation of the claws on the lathe.

[0040] Furthermore, both sides of the pressure plate 33 are screwed to the fixing plate 1 by bolts and locking screw holes 11 .

[0041] It should be noted that the clamping hole 10 arranged in the center of the fixed disk 1 described in this embodiment can be used to fix the fixed disk 1 through the clamping hole 10 by reverse installation of the vertical lathe claws; it can be understood that there are two ways to fix the fixed disk 1 in this embodiment, either by clamping the outer periphery of the fixed disk 1 by the positive clamping claws, or by inserting the reverse clamping claws into the clamping hole 10 for fixing; the advantage of this design is that it is highly operable and the operator can choose by himself.

[0042] Optionally, the flexible support plate 31 includes a support main board 310 and a locking plate 311 disposed on one side of the bottom of the support main board 310 ; a first through hole 312 for a bolt to pass through is disposed on a horizontal portion of the locking plate 311 .

[0043] Specifically, the locking plate 311 is an L-shaped structure as a whole, and its upper end is integrally connected and fixed to the supporting main board 310; the locking plate 311 is fixed to the fixing plate 1 by screwing the bolt passing through the first through hole 312 and the locking screw hole 11 on the fixing plate 1.

[0044] Optionally, the support main board 310 is provided with a plurality of second through holes along the length direction to cooperate with the support block 32 for fixation; it can be understood that the design of the plurality of second through holes facilitates the adjustment of the installation position of the support block 32 and the support main board 310.

[0045] In another embodiment, a strip hole 313 for bolts to pass through is provided in the middle portion of the support main board 310 along the length direction; it can be understood that, compared with the previous embodiment, the design of the strip hole 313 has higher flexibility in adjusting the installation position of the support block 32 than the design of several second through holes, and is more convenient for workers to operate.

[0046] Optionally, an inverted trapezoidal inner groove 320 is provided at the upper end of the support block 32, and the stepped shaft 5 can be snapped into the inner groove 320 of the support block 32; the inverted trapezoidal inner groove 320 is used to cooperate with the stepped shaft 5 to ensure the stability of the installation of the stepped shaft 5 on the support block 32, and the processing accuracy of the thrust washer slot 6 can be guaranteed.

[0047] Optionally, each of the support blocks 32 is provided with a fixing block 321 at both ends of a side surface at the bottom; the fixing block 321 is fixed to the support main board 310 by means of bolts and nuts; it can be understood that the fixing block 321 is integrally connected with the support block 32, and a through hole is provided on the fixing block 321; when in use, the bolt passes through the through hole, the second through hole or the strip hole 313 on the support main board 310 in turn, and the fixing block 321 is fixed to the upper end of the support main board 310 by cooperating with the nut.

[0048] When in use, start the vertical lathe, drive the turning tool 7 perpendicular to the bottom of the vertical lathe spindle to rotate, use the virtual circle 2 as the processing trajectory, and complete the thrust washer slot 6 processing of six stepped shafts 5 at one time; it has the advantages of high precision, high efficiency, and short time consumption.
