Description

TECHNICAL FIELD

[0001] The utility model relates to a tool, specifically to a differential assembly's tooling. BACKGROUND

[0002] The differential assembly is an important transmission component of the automobile, which can effectively reduce the side slip risk in the automobile driving process and improve the steering stability. The differential assembly needs to be fixed and limited by a tool during assembly and detection. In order to ensure the accuracy of assembly or detection, the differential assembly often has the requirements of concentricity and levelness when fixed and limited, so the tool needs to be fully compatible with the shape of the differential assembly, which often makes a tool only applicable to one type of differential assembly, resulting in poor versatility and narrow application range of the tool.

[0003] The patent application with publication number CN115870531A discloses a differential half shell cross shaft hole machining device, which includes a base, an axial positioning member and an angular positioning member. The axial positioning member extends in a first direction, and the two ends of the axial positioning member are detachably connected to the base and the differential half shell, so that the differential half shell is fixed relative to the base along the first direction. The angular positioning member is arranged in a direction perpendicular to the first direction and spaced apart from the axial positioning member. The angular positioning member extends in the first direction, and the two ends of the angular positioning member are detachably connected to the base and the differential half shell to prevent the differential half shell from rotating relative to the base about a rotation axis perpendicular to the first direction. The differential half shell cross shaft hole machining device described above can be matched with different types of differential half shells by replacing different axial positioning members and angular positioning members, thereby improving the applicability of different types of differential half shells.

DETAILED DESCRIPTION

[0023] The differential assembly's changeover tooling, it is by machine table 1, transmission table 2, adjusting mechanism 3, profiling positioning block 4 and driving mechanism 5 constitutes, machine table 1 is provided with transmission table 2, to bear workpiece through transmission table 2, through the transfer of transmission table 2, and then workpiece transfer, make workpiece can circulate between each station. Transmission table 2 is provided with adjusting mechanism 3 symmetrically, and the both sides of adjusting mechanism 3 are movably installed with profiling positioning block 4 through slide rail respectively;The machine table 1 of transmission table 2 side is provided with driving mechanism 5. The function of driving mechanism 5 is to drive adjusting mechanism 3 to work through driving mechanism 5, and then the position of profiling positioning block 4 is adjusted through the working adjusting mechanism 3, reduces or increases the spacing between profiling positioning block 4, and then the spacing between profiling positioning block 4 is adapted to the workpiece model (diameter), to ensure that profiling positioning block 4 can still accurately position workpiece after workpiece changeover through adjustment.

[0024] The adjusting mechanism 3 is composed of an assembling block 301, assembling short shafts 302, drive gears 303 and hexagonal nuts 304. The assembling short shafts 302 are inserted side by side on the assembling block 301, and the drive gears 303 are arranged on the assembling short shafts 302 respectively, and the drive gears 303 are engaged with each other. The top end of one of the assembling short shafts 302 is provided with a hexagonal nut 304. The profiled positioning blocks 4 on one side of the assembling block 301 are provided with drive racks 401, and the drive racks 401 are engaged with the drive gears 303. The assembling block 301 is fixedly connected with the transmission table 2. The hexagonal nut 304 is used to rotate the assembling short shaft 302 by rotating the hexagonal nut 304. Since the assembling short shafts 302 arranged side by side are connected through the drive gears 303, the assembling short shafts 302 arranged side by side and the drive gears 303 on the assembling short shafts 302 can be driven to rotate in the rotating process of the hexagonal nut 304. The drive gears 303 can drive the drive racks 401 on the profiled positioning blocks 4 on both sides of the assembling block 301 to move in the rotating process of the drive gears 303, so as to drive the profiled positioning blocks 4 to slide along the slide rails, thereby adjusting the distance between the profiled positioning blocks 4.

[0025] The bottom edge of the hexagonal nut 304 is provided with positioning teeth 305, and a plurality of groups of limiting teeth 306 are arranged at intervals on the assembling block 301, and the limiting teeth 306 are engaged with the positioning teeth 305. The assembling short shaft 302 between the hexagonal nut 304 and the assembling block 301 is sleeved with a reset spring 307. The drive gears 303 below the hexagonal nut 304 are connected with the assembling short shaft 302 through slide keys. The limiting teeth 306 are used to limit the position of the positioning teeth 305, and then limit the position of the hexagonal nut 304, so that the hexagonal nut 304 cannot rotate, and then the positions of the profiled positioning blocks 4 are limited in sequence through the assembling short shaft 302, the drive gears 303 and the drive racks 401, so as to prevent the profiled positioning blocks 4 from moving in the positioning process and ensure accurate positioning. The reset spring 307 is used to push the hexagonal nut 304 to reset and support the hexagonal nut 304 after the hexagonal nut 304 is reset, and then maintain the engagement between the positioning teeth 305 on the hexagonal nut 304 and the limiting teeth 306, thereby maintaining the limitation on the profiled positioning blocks 4.

[0026] The driving mechanism 5 is composed of a support plate 501, a translation air cylinder 502, a driving block 503, a translation sliding seat 504, a lifting sliding seat 505, a lifting air cylinder 506, a rotary motor 507 and a sleeve 508. The translation air cylinder 502 is arranged on the support plate 501, and the sliding block of the translation air cylinder 502 is provided with the driving block 503. The translation sliding seat 504 is movably arranged on the support plate 501 through a sliding rail, and is threadedly connected with the translation air cylinder 502. The lifting sliding seat 505 is movably arranged on the translation sliding seat 504 through a sliding rail, and the top of the translation sliding seat 504 is provided with the lifting air cylinder 506 (model CDQ2A32-200DCMZ-M9BL). The piston rod end of the lifting air cylinder 506 is fixedly connected with the lifting sliding seat 505. The rotary motor 507 is arranged on the lifting sliding seat 505, and the output shaft end of the rotary motor 507 is provided with the sleeve 508. The inner wall of the sleeve 508 is hexagonal. The support plate 501 is fixedly connected with the machine table 1. The rotary motor 507 is a servo motor (model 1FL6042-2AF21-1AA1). The translation air cylinder 502 drives the translation sliding seat 504 to move horizontally along the sliding rail through the driving block 503, so that the sleeve 508 is driven to move horizontally by the lifting sliding seat 505 and the rotary motor 507 in turn during the horizontal movement of the translation sliding seat 504. The lifting air cylinder 506 drives the lifting sliding seat 505 to lift, and then drives the rotary motor 507 to lift, so as to drive the sleeve 508 to lift. Through the horizontal movement and lifting of the sleeve 508, the sleeve 508 can be connected with the hexagonal nut 304 of the adjusting mechanism on both sides of the transmission table 2 respectively, so that the hexagonal nut 304 on both sides of the transmission table 2 can be screwed during the rotation of the sleeve 508 driven by the rotary motor 507.

[0027] When adjusting the differential assembly using the changeover tooling, as the transmission line transfers the transmission table 2 to the machine base 1, the translation cylinder 502 of the drive mechanism operates. The translation cylinder 502 sequentially drives the sleeve 508 to move above the adjustment mechanism on one side of the transmission table 2 via the translation slide 504, the lifting slide 505, and the rotary motor 507. After the sleeve 508 is in position, the lifting electric cylinder 506 starts, sequentially driving the sleeve 508 downward via the lifting slide 505 and the rotary motor 507, so that the sleeve 508 is fitted onto the hexagonal nut 304 of the adjustment mechanism. At the same time, the hexagonal nut 304 is pressed down, disengaging the positioning teeth 305 and the limiting teeth 306 of the hexagonal nut 304. After the positioning tooth 305 disengages from the limiting tooth 306, the rotary motor 507 is started. The rotary motor 507 sequentially drives the contour positioning blocks 4 on both sides of the adjustment mechanism to move via the sleeve 508, hexagonal nut 304, assembly short shaft 302, drive gear 303, and drive rack 401, thereby adjusting the position of the contour positioning block 4 on one side of the transmission table 2. After the adjustment is completed, the sleeve 508 returns to its original position. During the disengagement of the sleeve 508 from the hexagonal nut 304, the return spring 307 pushes the hexagonal nut 304 to return to its original position, causing the positioning tooth 305 of the hexagonal nut 304 to re-engage with the limiting tooth 306, thus determining the position of the contour positioning block 4. After the position of the contour positioning block 4 on one side of the transmission table 2 is adjusted, the sleeve 508 moves to the other side of the transmission table 2, and the above process is repeated to adjust the position of the contour positioning block 4 on the other side of the transmission table 2.

[0028] This differential assembly changeover fixture can adjust the position of the contour positioning block via an adjustment mechanism, thereby enabling precise positioning of the differential assembly using the adjusted contour positioning block. Furthermore, the adjustment mechanism can be driven by a drive mechanism, which significantly improves adjustment efficiency and reduces labor intensity compared to disassembly and replacement of parts. It also allows for convenient and simplified adjustments, enabling batch adjustments. This solves the problems of low adjustment efficiency, high labor intensity, and cumbersome adjustments associated with existing fixtures.
