Description

Technical Field

[0001] The utility model relates to the technical field of thin-wall washer processing, and particularly relates to a boring tooling for thin-wall washers. Background Art

[0002] A washer refers to a part placed between the connected parts and the nut, generally a flat metal ring, which is used to protect the surface of the connected parts from being scratched by the nut and to disperse the pressure of the nut on the connected parts. Thin-wall parts of washers are widely used in industry. However, in some special industries, there are relatively high-precision dimensional requirements for their inner hole sizes. Especially for washers with a relatively large outer diameter, high-precision inner holes, and thin thickness, when using existing normal processing equipment, during the machining boring process of the washers, due to poor clamping effect, they are easily deformed by force, resulting in product deformation and extremely easy out-of-tolerance of the inner hole size. Therefore, in order to meet the processing requirements of thin-wall washers, improve processing efficiency, and avoid product deformation caused by radial force during the clamping process, a boring tooling with a simple structure and convenient operation is provided to meet batch processing and reduce processing costs. Content of the Utility Model

The cover plate and the bottom plate are connected by a screwing method to clamp and fix the thin-wall workpiece to be processed placed between the cover plate and the bottom plate.

[0005] Furthermore, for the boring tooling for thin-wall washers of the utility model, the cover plate is set as a disc structure. The processing through hole is arranged at the central position on the top of the cover plate. An accommodating cavity communicating with the processing through hole is arranged at the bottom of the cover plate. The inner diameter of the accommodating cavity is larger than that of the processing through hole, and an internal thread is arranged on the inner wall surface of the accommodating cavity. The cover plate is screwed to the bottom plate through the internal thread.

[0006] Further, a boring tooling for thin-walled washers according to the present utility model is adopted. The bottom plate is arranged in a stepped shaft structure, including a supporting part and a connecting part connected in sequence. A stepped part is arranged between the supporting part and the connecting part. The supporting cavity is arranged at the top of the supporting part and is coaxially arranged with the processing through hole. An external thread matching the internal thread is arranged on the outer wall surface of the supporting part. The cover plate and the bottom plate are screwed together through the accommodating cavity and the supporting part to form a detachable connection structure.

[0007] Further, a boring tooling for thin-walled washers according to the present utility model is adopted. The outer diameter of the connecting part is smaller than that of the supporting part, while the height of the connecting part is greater than that of the supporting part. The outer diameter of the stepped part is greater than that of the supporting part, while the height of the stepped part is smaller than that of the supporting part. The bottom plate is fixedly connected to the processing machine tool through the connecting part.

[0008] Further, a boring tooling for thin-walled washers according to the present utility model is adopted. Chamfering transition structures are also arranged along the circumferential direction on the top surface and the bottom surface of the stepped part.

The locking holes are located in the middle of the outer side surface of the cover plate, and there are four locking holes, and the four locking holes are evenly arranged along the circumferential direction in the cover plate.

[0011] Further, a boring tooling for thin-walled washers according to the present utility model is adopted. Chamfering transition structures are also arranged along the circumferential direction on the top surface and the bottom surface of the cover plate.

[0012] By adopting a boring tooling for thin-walled washers according to the present utility model, since a processing through hole is arranged in the cover plate and a supporting cavity matching the processing through hole is arranged in the bottom plate, the thin-walled part to be processed is clamped and fixed by the cover plate and the bottom plate, so that the thin-walled washer to be processed changes from being stressed radially to being stressed axially, effectively avoiding the problem of product deformation caused by radial force. Thus, it can be seen that by adopting the boring tooling of the present utility model, it can be used to process different specifications of washers with the same outer diameter, greatly improving the processing efficiency, not only meeting batch processing, but also reducing the processing cost, providing a reliable technical support for batch and large-scale production.
