Embodiment Construction

[0013] see image 3 , the invention discloses a torsion spring clamp for quick installation. As shown in the figure: it includes two symmetrical clamp arms 1, 2 connected axially by a rotating pin shaft 4 in the middle, and the clamp arms 1, 2 are divided into a front section and a rear section by a shaft joint; the clamp arm The inner ends of the front sections of 1 and 2 each have a positioning hole, and a return pressure spring 5 is connected between the inner ends of the rear sections of the clamp arms 1 and 2; the rotating pin shaft 4 is fixed through a positioning groove forward Positioning clip 3.

[0014] The steps of quick installation of torsion spring using the above-mentioned clamps are (please combine image 3 refer to Figure 4 ): Insert the torsion spring 6 into the positioning groove of the positioning clip 3 of the clamp to prevent the torsion spring from turning over when it is twisted and deformed by force, and it is easy to pop out and hurt people; back ...

Abstract

The invention relates to a clamp and a method for quickly installing a torsion spring. The clamp comprises two symmetrical clamp arms connected through the coupling of a rotary pin roll, and each clamp arm is divided into a front section and a back section by the coupling part; the inner ends of the front sections of the clamp arms are respectively provided with a locating hole, and a return compression spring is connected between the inner ends of the back sections of the clamp arms; and the rotary pin roll fixes a forward locating clip of a locating slot through coupling. The invention mainly solves the technical problem that the torsion spring is easy to jump out from an end opening of a tool rod to hurt people when the tool rod is used for installing the torsion spring. Only one operator is needed to complete installation operations, and the installation mode is simple, convenient, safe and efficient.

Description

technical field [0001] The invention relates to a spring installation tool and an installation method, in particular to a clamp for quickly installing a torsion spring and a quick installation method for the torsion spring. Background technique [0002] At present, more and more products need to be equipped with torsion springs to meet their special functional requirements. Wherein, the torsion spring generally has a helical torsion spring body and two metal feet positioned at two ends of the torsion spring body. [0003] The installation tools and installation methods of existing torsion springs are as follows: figure 1 , 2 Shown: An operator first puts two open-ended tool sticks A and B onto the two metal legs of the torsion spring C, and pushes his hands in two opposite directions (the force is F) to push the The torsion spring is stretched, and then the torsion spring C is moved to the installation position in the stretched state. Thereafter, another operator needs t...
