Embodiment 1

[0021] The processing method of the bolt fillet includes the following specific steps:

[0022] S1. Clean the surface of the bolt with a steel wire, then wash it with clean water, dry it and reserve it for later use. The temperature of the clean water is 45°C, the number of cleanings is 2 times, the drying temperature is 80°C, and the drying time is 1.2h;

[0023] S2. Calculate the remaining grinding allowance of the outer circle, and select a suitable round-end turning tool to install on the lathe according to the size of the fillet;

[0024] S3. After fixing the bolts, apply a layer of solvent evenly on the position to be processed. After the coating is completed, turn on the lathe immediately to start processing the rounded corners. After the rounded corners are processed, wash them with clean water and dry them. The temperature of the clean water is 45 ℃, the number of cleaning times is 2 times, the drying temperature is 80 ℃, and the drying time is 1.2h; the solvent tempe...

[0028] The processing method of the bolt fillet includes the following specific steps:

[0029] S1. Clean the surface of the bolt with a steel wire, then wash it with clean water, dry it and set it aside. The temperature of the clean water is 48°C, the number of cleanings is 2 times, the drying temperature is 90°C, and the drying time is 1.5h;

[0030] S2. Calculate the remaining grinding allowance of the outer circle, and select a suitable round-end turning tool to install on the lathe according to the size of the fillet;

[0031] S3. After fixing the bolts, apply a layer of solvent evenly on the position to be processed. After the coating is completed, turn on the lathe immediately to start processing the rounded corners. After the rounded corners are processed, wash them with clean water and dry them. The temperature of the clean water is 48 ℃, the number of cleaning times is 3 times, the drying temperature is 90 ℃, and the drying time is 1.5h; the solvent temperature is 50...

Abstract

The invention discloses a machining method of a rounded corner of a bolt. The machining method comprises the following specific steps: the surface of the bolt is cleaned through a steel wire, and an appropriate round-nose turning tool is selected to be mounted on a lathe; after the bolt is fixed, a to-be-machined position is evenly coated with a layer of solvent, and after coating is completed, the lathe is immediately started to start machining the rounded corner; the dried bolt is sequentially subjected to polishing and acid cleaning activation, and after cleaning, natural air drying is conducted; and the bolt is placed in an electroplating reagent solution to be electroplated, and the bolt is machined. Abrasion and adhesion of cuttings of the turning tool can be prevented, grinding force and frictional heat are reduced, and the surface quality of the rounded corner of the bolt is improved.

Description

technical field [0001] The invention belongs to the technical field of bolts, and in particular relates to a method for processing bolt fillets. Background technique [0002] With the vigorous development of modern industry, the requirements for high-strength bolts in various fields are getting higher and higher, especially for major projects such as large aircraft in the aviation and aerospace fields, the technical requirements for special bolts are even higher. At present, the processing technology of bolt fillet is mostly directly cut by turning tool. This process has the problems of serious wear of the turning tool and high temperature at the processing place. In view of this, it is necessary to improve the traditional processing method of bolt fillet . Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a method for processing bolt fillets, which can prevent the turning tool from we...
