Description

Technical Field

[0001] This application relates to the technical field of thrust plate positioning devices, and in particular to a thrust plate processing positioning device. Background Technology

[0002] A thrust washer is a metal plate used to restrict the axial movement of mechanical components. Its main functions include axial positioning, bearing axial loads, and reducing wear. In an engine, the thrust washer primarily serves as an axial support for the crankshaft, ensuring its axial rotation while preventing axial movement.

[0003] like Figure 1 As shown, the thrust plate 5 includes a ring body 51 and four protrusions 52 disposed on the inner ring of the ring body 51. The protrusions 52 are integrally formed with the ring body 51, and the four protrusions 52 are evenly distributed around the axis of the ring body 51. In the traditional process of machining the thrust plate, the thrust plate is placed in the machining area so that the four protrusions correspond to the machining components, then the clamping components clamp the thrust plate, and finally the machining components machine the thrust plate. During the installation of the thrust plate, the time wasted in aligning the thrust plate with the machining components is relatively large, and the positioning efficiency of the thrust plate is low, which needs improvement. Utility Model Content

[0017] Optionally, the connecting rod is connected with a reset member, and the reset member is used to drive the driving plate to reset.

[0018] By adopting the technical scheme, after the driving plate is rotated, the reset member drives the driving plate to reset, so as to facilitate the next operation.

[0019] Optionally, two driving plates are rotationally connected to the positioning seat, the number of the driving plates is the same as the number of the connecting rods, and the driving plates correspond to the connecting rods one by one.

The driving disc is moved upward, the elastic members are elastically deformed under pressure and have a tendency to elastically reset, the jacking block protrudes out of the through hole and abuts against the thrust piece, so that the thrust piece is separated from the ring groove, and the processed thrust piece is convenient to take. When the thrust piece is taken away, the driving disc is loosened, the elastic members are elastically reset, and the elastic members force the driving disc to reset, so that the jacking block is retracted into the through hole, thereby facilitating the next operation.

[0023] Optionally, four jacking blocks are arranged on the driving disc, the four jacking blocks are uniformly distributed around the axis of the driving disc, the number of the through holes is the same as that of the jacking blocks, and the jacking blocks correspond to the through holes one by one.
