Abstract
The utility model discloses a stretching tool of an energy storage spring. The stretching tool of the energy storage spring comprises a rod body. One end of the rod body is provided with a wedge-shaped inserting portion along the axis direction, and a hook body is arranged on the rod body deviating the position of one end of the wedge-shaped inserting portion. Compared with the prior art, the stretching tool of the energy storage spring is simple in structure, low in cost, free of enabling the spring to deform and be damaged in the process of stretching operation, and capable of effectively protecting the spring and personal safety of operating personnel. When the stretching tool of the energy storage spring is used, the upper end of the energy storage spring is fixed firstly, the hook body of the rod body penetrates through a small hole of a positioning piece of the lower end of the spring, and the wedge-shaped inserting portion is inserted into a gap of a device and taken as a support point. According to the principle of leverage, the other end of the rod body is pressed downward just by means of small force, the spring can be stretched by force, and therefore, dismantling operation of the spring is simple, fast, safe, savable in time and effort, and capable of greatly improving work efficiency.
Description
Technical field
The utility model relates to mechanical erection and service kit technical field, especially a kind of instrument that makes energy-stored spring be elongated to Len req.
Background technology
In some industrial production, can relate to the installation of spring, after mounting spring need to stretch or be compressed to certain length usually, could be with spring fitting to desired location.And energy-stored spring refers to be at ordinary times stretching or compressive state, lean on the spring restoring force and the spring of work done, it is the critical elements in the breaker, the intensity of energy-stored spring and service life are to stability and the security important of breaker operation, when overhauling at the manufacturing breaker with to breaker, all can relate to the installation of energy-stored spring.Because the energy-stored spring pulling force is larger, the operating space is less, causes the dismounting of spring and installs all very difficult.The mode of existing installation energy-stored spring is that the spacer on the spring is inserted on the rotating shaft bar of mechanism, fix with nut check, then three to four large size screwdrivers being inserted in the slit between the turn forces spring stress to elongate, the lower end spacer moves down under spring elongation effect, after being elongated to described length, insert alignment pin lower end spacer and fixing ear are connected and fixed, the taking-up screwdriver is finished spring fitting.Such mode not only wastes time and energy, and affects operating efficiency, also might be to the spring injury, and when the large size screwdriver inserted the spring slit as firmly unstable, screwdriver easily ejects, and may damage operating personnel, has certain potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of energy-stored spring stretching tool, and this energy-stored spring stretching tool can solve the effort that stretches when existing energy-stored spring is installed, inefficiency, spring easy damaged and easily cause the problem of personal injury.
In order to address the above problem, the technical solution adopted in the utility model is: this energy-stored spring stretching tool includes a body of rod, one end of the described body of rod is provided with Wedge insertion section vertically, is provided with coupler body in the position of the described Wedge insertion of described body of rod deflection section one end.
In the above-mentioned energy-stored spring stretching tool technical scheme, technical scheme can also be more specifically: the described body of rod has handle, is set with Anti-slip cover on the described handle.Described coupler body has threaded rod, and described coupler body is by threaded rod and described body of rod thread connection.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect: it is simple in structure, and cost is low, and stretched operation can not make camber of spring, damage, can effectively protect spring and operating personnel's personal safety; First fixing energy-stored spring upper end, again the coupler body on the body of rod is pierced in the aperture on the spacer of spring lower end, in the slit with Wedge insertion section insertion apparatus, take it as fulcrum, according to lever principle, only need the very little strength of cost that the body of rod other end is pressed down, spring just can stressedly elongate, simple and quick, the safety of the dismounting of spring, time saving and energy saving, greatly improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of this energy-stored spring stretching tool embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Energy-stored spring stretching tool shown in Figure 1 includes the body of rod 3 and the coupler body 2 that is installed on the body of rod 3 of action bars, and the body of rod 3 is the elongate cylinder barred body, and an end of the body of rod 3 is Wedge insertion section 1, and this Wedge insertion section 1 has a smooth inclined-plane; Coupler body 2 is installed in the position of these Wedge insertion section 1 one ends of deflection on the body of rod 3, coupler body 2 has the threaded rod that is threadedly connected on the body of rod 3, the installed position that is positioned at coupler body 2 in the both sides of the body of rod 3 is provided with the plane vertical with this threaded rod, coupler body 2 is fixed on the body of rod 3 by pad and nut check, and the inclined-plane of the hook portion of coupler body 2 and Wedge insertion section 1 is relatively arranged on the both sides of the body of rod 3; The other end of the body of rod 3 is the handle of action bars, is set with Anti-slip cover 4 in the grip.
When energy-stored spring is installed, at first spring upper end spacer is packed into the rotating shaft bar, fix with nut check, again the coupler body on the action bars is pierced into the aperture on the spacer of spring lower end, Wedge insertion section is injected in switch and the dolly chassis slit, make the inclined-plane of Wedge insertion section 1 down, take inclined-plane and chassis contact site as fulcrum, Anti-slip cover 4 parts of hand-held operation bar, exert pressure downwards, according to lever principle, only need the very little strength of cost the other end of the body of rod 3 can be depressed, energy-stored spring just can stressedly elongate, embed spacing special-purpose clamp after, make on the energy-stored spring, the spacer of lower end and this clamp connect so that spring length reaches the position that needs installation, coupler body 2 is taken out in the aperture of lower end spacer, the lower end spacer is moved to two of bottoms fixedly between the ear, inserting alignment pin fixedly, ear and lower end spacer are connected and fixed, after taking out clamp, the energy-stored spring installation.
