Description

Technical Field

[0001] The utility model belongs to the technical field of bolts, and particularly relates to an auxiliary tooling for rolling threads of large-sized bolts. Background Technique

[0002] For the thread rolling process of large-sized bolts, a manual thread rolling method is generally adopted. Currently, a cylindrical support is arranged at the bottom between two thread rolling rollers of a thread rolling machine, and a resisting rod is arranged at the rear side of the support. The end of the bolt is attached to the end of the resisting rod, and the surface of the bolt is tangent to the support. The thread is processed by the two thread rolling rollers.

[0003] During the working process, the staff holds the bolt by hand and needs to ensure that the bolt is attached to the support. The staff needs to apply force to control the position of the bolt. The holding point of the staff is at the head end of the bolt, which is not conducive to the overall control of the bolt, and the staff needs to bear a certain resistance generated during the thread rolling process, especially for the processing of high-strength bolts. If the position deviates, it will affect the stable processing of the thread groove. Therefore, designing an auxiliary tooling that is conducive to applying force is a problem that needs to be solved by the staff in this field. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary tooling for rolling threads of large-sized bolts. By designing a new type of auxiliary tooling, the position of the bolt can be accurately controlled. During the thread rolling process, the staff can directly apply pressure downward on the bolt, greatly improving the stability during the thread rolling process of the bolt. Moreover, the bolt will not be affected by the reverse force during the thread rolling process, improving safety, thereby improving the forming quality of the thread on the bolt and ensuring the product quality of the bolt.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0030] The support base 4 is provided with an arc-shaped opening 401. At the top of the support base 4, there is a placement opening 402 connected to the arc-shaped opening 401. Inside the arc-shaped opening 401, there is a bolt support 403 with an arc-shaped structure. Two support bases 4 are fixed side by side on the top of the sliding seat 2 and are linearly arranged with the positioning block 3.

[0031] A number of positioning end rods 5 are fixed on the outer side of one support base 4 close to the positioning block 3. At the end of the positioning end rod 5, there is a round head end 501.

[0032] Among them, as Figures 1-3 shown, the adjusting mechanism includes an adjusting bolt 302 and a group of guide rods 303. The adjusting bolt 302 passes through the U-shaped seat 202 and is threadedly connected to the U-shaped seat 202. The top end of the adjusting bolt 302 is rotatably connected to the bottom of the positioning block 3. The guide rod 303 is fixed to the bottom of the positioning block 3.
