Problems solved by technology

This processing method requires multiple clamping of the workpiece. Not only is the product size consistency poor, but the surface roughness is also difficult to guarantee. Multiple clamping processes also result in poor product accuracy consistency, which leads to certain hidden dangers in product quality control and safe use.

Embodiment Construction

[0023] The specific embodiments of the present invention are given below with reference to the accompanying drawings, which are used to further describe the constitution of the present invention.

[0024] Processing technology reference of titanium alloy ring groove rivets with large length-to-diameter ratio in this embodiment figure 1 , first grind the blank to make the diameter of the blank consistent, and then use the supporting chuck to clamp the blank to the lathe processing equipment (that is, the center type CNC lathe), first process the process ring groove, and then Carry out the processing of the broken neck groove, and then process the working rod, and finally cut off according to the size to obtain the overall size of the head.

[0025] The working steps are described as follows:

[0026] 1. Clamping one end of the head of the blank in 1 direction, use the outer circle rough turning tool to flatten the outer circle and the end face of the other end, the spindle spe...

Abstract

The invention relates to a processing process of a ring groove rivet, and in particular relates to the processing process of a titanium alloy ring groove rivet with a big length-to-diameter ratio. The processing process belongs to the technical field of a ring groove rivet processing process. The processing process of the titanium alloy ring groove rivet with the big length-to-diameter ratio is characterized in that process ring grooves, a broken neck groove, a work rod part and a head of a blank after grinding are sequentially formed by disposable lathing molding by adopting a numerically controlled lathe. In the processing process, the high precision of ring groove processing is realized by utilizing the high precision of the lathe, the efficient processing is realized by utilizing the numerically controlled automatic fast feeding, the excircle precision of the ring groove rivet with the big length-to-diameter ratio, processed by the process, is high, and the surface roughness and the batch product size consistency are superior to a product processed by the conventional process, and therefore, the size and the mechanical property stability of the entire product is improved, and final batch product testing indicators are superior to the conventional product.

Description

[0001] technical field [0002] The invention relates to a processing technology of a ring groove rivet, in particular to a processing technology of a titanium alloy ring groove rivet with a large aspect ratio, and belongs to the technical field of ring groove rivet processing technology. Background technique [0003] Titanium alloy ring groove rivets are commonly used fasteners in aerospace. Its structure and composition refer to the attached figure 1 , including a head 1, a working rod part 2, a broken neck groove 3, a ring groove polished rod 4 and a process ring groove 5. At present, the traditional processing method of titanium alloy ring groove rivets is to rough the basic outline first, and then roll the ring groove by rolling equipment. This processing method requires multiple clamping of the workpiece. Not only is the product size consistency poor, but the surface roughness is also difficult to guarantee. Multiple clamping processes also result in poor product a...
