Description

Technical Field

[0001] The utility model relates to the technical field of workpiece cutting processing, in particular to a cutting processing fixture for thin-walled ring-shaped workpieces. Background Technique

[0002] Thin-walled ring-shaped parts are components widely used in various mechanical equipment or devices. When cutting and processing the outer contour of such workpieces, in order to prevent the workpiece from deforming during the processing, a closed-ring pressing plate is usually used to press and clamp the workpiece. This clamping method has high requirements for the flatness and planeness of the pressing plate surface, and the processing difficulty is large. Moreover, as the outer dimension of the workpiece increases, the shape and dimension of the pressing plate also gradually increase, and the materials required for manufacturing the fixture also increase accordingly. This not only increases the fixture manufacturing cost, but also the machining accuracy of the pressing plate is not easy to guarantee, which easily increases the workpiece clamping error and affects the cutting processing accuracy of the workpiece.

[0003] When the existing fixture is in use, usually the workpiece is clamped once, and only one feature element on the surface of the workpiece can be cut and processed. When multiple feature elements of the workpiece need to be cut and processed, additional fixtures need to be designed and manufactured, resulting in a large amount of resource waste.

[0004] In the patent document with the publication number of CN220659986U, a cutting processing fixture for thin-walled ring-shaped workpieces is proposed. The device includes a base and a plurality of pressing devices. The pressing device includes a main support block, a support rod, a support rod and a pressing plate. The lower ends of the support rod and the support rod are both screwed to the base, the upper end of the support rod is screwed to the locking nut, the base is also fixedly connected to the main support block, and a main positioning step is provided on the surface of the main support block, a limiting hole is provided on the surface of the pressing plate, a boss is provided on the surface of the thin-walled ring-shaped workpiece, the support rod also passes through the limiting hole, and the upper end of the support rod abuts against one end of the pressing plate, and the boss is clamped between the other end of the pressing plate and the main positioning step. Adopting the technical solution of the utility model, when clamping the boss of the thin-walled ring part, if the upper end of the thin-walled ring part can extend upward or downward, the upper end surface or the inner wall surface of the thin-walled workpiece can be cut and processed. Compared with the prior art, this fixture has a wide application range and reduces unnecessary waste of fixture manufacturing resources.

[0005] However, it is not easy to rotate the fixed workpiece with this device, thus reducing the cutting processing efficiency of the workpiece.
