Description

Technical Field

[0001] This utility model relates to the field of aerospace machining technology, specifically a universal clamping platform for machining pipe joint forgings using a lathe four-jaw chuck. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Pipe fitting forgings are widely used in aerospace components, requiring precision machining of their threads on a lathe. Due to the diverse structures and varying dimensions of pipe fittings, traditional thread machining of pipe fittings required the creation of clamping dies for each structure and dimension (e.g., ...). Figure 1 (As shown). When the dimensions of one end of the pipe fitting change, a special mold needs to be re-machined. Even if the dimensions do not need to change, a special mold needs to be re-machined when the included angle of the fitting changes (e.g.). Figure 2 As shown in the figure, this makes the processing steps cumbersome, time-consuming and labor-intensive, greatly slowing down the processing of pipe fittings.

[0004] Based on the above reasons, this utility model designs a universal clamping platform for machining pipe joint forgings using a lathe four-jaw chuck. It only requires machining positioning brackets of different specifications, and then selecting the appropriate bracket according to the type and size of the forging to complete the production, which greatly improves the efficiency of forging machining. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a universal clamping platform for machining pipe joint forgings using a lathe four-jaw chuck. It only requires machining positioning brackets of different specifications, and then selecting the appropriate bracket according to the type and size of the forging to complete the production, which greatly improves the efficiency of forging machining.

[0006] To achieve the above objectives, this utility model provides a universal clamping platform for machining pipe joint forgings using a lathe four-jaw chuck. The platform includes a clamping platform, a positioning bracket, bracket connecting bolts, a forging, clamping bolts, and fixing holes. The clamping platform has upper and lower layers, each with multiple fixing holes. A positioning bracket is mounted on the fixing holes of the lower layer of the clamping platform, and the forging is mounted on the positioning bracket. The forging is clamped by clamping bolts mounted on the fixing holes of the upper layer of the clamping platform. The positioning bracket is mounted on the fixing holes of the lower layer of the clamping platform via bracket connecting bolts.

[0007] The positioning bracket is equipped with a crescent-shaped support for holding the forging.

[0008] The fixing holes on the upper and lower layers of the clamping platform correspond one-to-one in the axial direction.

[0009] The forgings are right-angled, bent, or other pipe fittings.

[0010] Compared with the prior art, this utility model fixes the forging parts to be processed through a clamping platform and a positioning bracket, which makes it easier to perform thread finishing on the forging parts. Furthermore, the fixing holes on the upper and lower parts of the armor platform, together with the fixing bolts, can freely fix forging parts of different sizes and shapes, achieving greater flexibility. This utility model can complete production simply by changing the positioning bracket, changing the processing method of making one or two sets of molds for each type of pipe joint in the prior art, greatly reducing processing costs and improving work efficiency.
