Problems solved by technology

[0004] 1. The thermal expansion coefficient of aluminum alloy is large, and the material itself is easier to deform than steel. When the aluminum alloy plate is welded, the strength of the simple bolt puller is not enough to restrain the strong welding internal stress, and the thermal deformation is large and difficult to control.
[0005] 2. Due to the different degrees of deformation of the aluminum alloy plate under heating conditions, there is a complex deformation trend of convex and concave. Therefore, the simple bolt puller used for fixing the tire must be constantly adjusted for tightness, but the operation Inconvenient and difficult to construct

Abstract

The invention discloses an adjustable screw elastic puller and a manufacturing method thereof. The adjustable screw puller includes a nut, a clamping plate, a hook bolt, a handle and a bushing, the bushing is set outside the hook bolt, the hook bolt is threaded with the nut, the clamping plate is located on the bushing, and the handle is symmetrical Set on the nut. The manufacturing method of the adjustable screw puller includes the following steps: S1, symmetrically welding the handle on the nut to obtain a nut handle connector; S2, aligning the second short side of the clamping plate with the end of the bushing , connected by double-sided corner welding to obtain the clamp bushing connector; S3, put the clamp bush connector outside the straight section of the hook bolt, with the clamping end facing the hook head side; connect the nut and the The threaded connection area of ​​the hook bolt is threaded to obtain an adjustable screw tension puller. The adjustable screw elastic puller of the invention has high strength, is easy to control deformation, is convenient to use, and has a simple manufacturing method.

Description

technical field [0001] The invention relates to the technical field of ship assembly, in particular to an adjustable screw elastic puller for welding and fixing an aluminum alloy structure on a frock tire frame and a manufacturing method thereof. Background technique [0002] The puller is an essential tool for the welding of the hull structure on the tooling frame. In the past, a simple puller made of twisted steel flat bars was generally used in the construction process of steel ships. Small, requires a large quantity and is not easy to reuse, and the consumables are serious. But considering the welding quality on the tooling tire frame, so far, this kind of puller has been used on steel products. [0003] However, for the aluminum alloy hull structure, the thickness of the aluminum alloy plate is relatively thin, and it is easy to deform. purpose of deformation. However, this simple bolt puller has the following disadvantages in the process of welding aluminum alloy pl...
