Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a rolling thread clamping tooling for double-headed bolts. Background Technique

[0002] A double-headed bolt, also called a double-headed screw or double-headed stud. It is used for the fixed connection function of machinery. Both ends of the double-headed bolt have threads, and the middle screw rod can be thick or thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, tower cranes, large-span steel structures and large buildings, etc. Among them, the clamping device for bolt processing is a fixing device that clamps and fixes the bolt when processing the bolt, so as to facilitate operations such as rolling threads, grinding, and polishing on the fixed bolt. Therefore, when processing bolts in the existing market, the indispensable device is the clamping device.

[0003] The existing Chinese patent with the publication number CN214518835U discloses a clamping device for bolt processing. The key points of its technical solution are as follows: including a box body, both left and right sides of the inner wall of the box body are fixedly installed with bearing A. The inner parts of the two bearing A are respectively sleeved with a reverse threaded rod and a forward threaded rod. The bottom of the inner wall of the box body is fixedly installed with a bracket. The top of the bracket is sleeved with bearing B, and the other ends of the reverse threaded rod and the forward threaded rod are sleeved inside the bearing B. The surfaces of the reverse threaded rod and the forward threaded rod are both threadedly connected with a sliding rod and an auxiliary rod. Place the bolt inside the placement groove, control the control wheel to drive the two pushing sliders to slide in the same direction. There are arc-shaped ramps on the opposite sides of the two pushing sliders, which can slowly straighten the inclined bolt. Due to the magnetic block, the bottom plane of the bolt is magnetically linked to the top of the magnetic block, so that the bolt can stand up, making it more convenient for subsequent processing of the bolt.

[0004] The above-mentioned existing technical solution has the following defects. Although the above technical solution can make the bolt stand up, making it more convenient for subsequent processing of the bolt, in the above technical solution, manual rotation of the control wheel is still used to clamp and fix the bolt. The manual method is time-consuming and laborious, not convenient for use, and easily reduces its work efficiency. Summary of the Utility Model
