Inclination angle alignment controllable thread tightening mechanism and operation method

Abstract

The invention relates to an inclination angle alignment controllable thread tightening mechanism and an operation method. The inclination angle alignment controllable thread tightening mechanism comprises a tightening mechanism (1), a connecting bracket (3) and a swing wrench (5), wherein the tightening mechanism (1) is connected with the swing wrench (5) through a telescopic two-stage universal joint connecting shaft (2) and transmits torque and rotation action; and an elastic assembly (4) is arranged between the swing wrench (5) and the connecting bracket (3) and provides elastic support forthe swing wrench (5). During thread installation, the tightening mechanism (1) drives the swing wrench (5) to rotate, a centrifugal mechanism on the swing wrench (5) can provide centrifugal force ina rotating process, and the swing wrench (5) deflects under the combined action of centrifugal force, elastic force of the elastic assembly and internal resistance of the mechanism. Under the condition that a certain included angle exists between central shafts of two parts in threaded fit, inclination angle deflection alignment can be achieved, threads can be screwed in, in the working conditionof mechanically aligning and installing the threads, after the central points of two matched parts are aligned, inclination angle alignment and thread assembly tightening can be carried out.

Description

technical field [0001] The invention relates to the technical field of engineering installation, in particular to a screw tightening mechanism with controllable inclination angle alignment and an operation method. Background technique [0002] The current thread tightening machine tightening mechanism can successfully complete the thread tightening under the condition of alignment, but the thread cannot be smoothly screwed in when the thread is skewed. Especially in the working condition of using mechanical alignment to install the thread, even if the center points of the two parts that need to be threaded have been aligned, the thread cannot be screwed in if there is an angle between the central axes. [0003] For example, the Chinese invention patent application whose publication number is CN109434757A discloses an auxiliary installation device capable of adjusting the inclination angle of embedded bolts and its use method. The right clamp is installed on the right screw a...

Problems solved by technology

However, the adjustment angle of the installation device is determined by manually observing the axis of the bolt sleeve and the scale line on the dial to determine the size of the adjustment angle, and there is a certain error; in addition, the left and right clamps need to be fixed on the concrete when the device is working. On the mold, when the size of the concrete mold is large or the shape of the mold adopts a cylindrical structure, it is difficult to fix; when the center points of the two parts that are threaded have been aligned, it cannot be fixed when there is an angle between the central axes.
