Abstract
The utility model discloses a kind of stretching tools for tension spring, including hydraulic cylinder, strut, fixed link and fixing seat, the fixed link is fixedly connected with fixing seat, strut is by bolted splice in fixed link, and strut is divided into driving portion and struts portion by the hinge joint between strut and fixed link, the length of driving portion is greater than the length in the portion that struts, and hydraulic cylinder is placed in fixing seat side, and the hydraulic cylinder shaft of hydraulic cylinder contacts on driving portion.The utility model structure is simple, and convenient for the abundant spray painting of tension spring, using effect is good.
Description
Technical field:
The utility model relates to a kind of stretching tools for tension spring.
Background technique:
When existing tension spring spraying antirust paint, since tension spring is to shrink closed state, directly paints, tension spring is caused to paint
Unevenly, after tension spring stretches, many positions are not all directed onto, rust-proof effect is poor.
Utility model content:
The utility model is to provide a kind of stretching work for tension spring to solve the above-mentioned problems of the prior art
Dress.
Technical solution used by the utility model has: a kind of stretching tool for tension spring, including hydraulic cylinder, strut,
Fixed link and fixing seat, the fixed link are fixedly connected with fixing seat, strut by bolted splice in fixed link, and strut with
Strut is divided into driving portion and struts portion by the hinge joint between fixed link, and the length of driving portion is greater than the length in the portion that struts, hydraulic
Cylinder is placed in fixing seat side, and the hydraulic cylinder shaft of hydraulic cylinder contacts on driving portion.
Further, the end of the fixed link is equipped with the first engaging lug, is equipped with the second engaging lug in the end for strutting portion.
Further, the ends bent for the strutting portion and bending edges for being formed in parallel with fixed link, the second engaging lug are set
In on bending edges.
The utility model has the following beneficial effects:
The utility model structure is simple, and convenient for the abundant spray painting of tension spring, using effect is good.
Detailed description of the invention:
Fig. 1 is the utility model structure chart.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, a kind of stretching tool for tension spring of the utility model, including hydraulic cylinder 61, strut 62, fixed link
63 and fixing seat 64, fixed link 63 be fixedly connected with fixing seat 64, strut 62 by bolted splice in fixed link 63, and strut
Strut 62 is divided into driving portion 621 and struts portion 622 by the hinge joint between 62 and fixed link 63, and the length of driving portion 621 is greater than
The length in portion 622 is strutted, hydraulic cylinder 61 is placed in 64 side of fixing seat, and the hydraulic cylinder shaft of hydraulic cylinder 61 contacts at driving portion 621
On.
To be equipped with the first engaging lug 631 in the end of fixed link 63, being set in the end in the portion that struts 622 convenient for connecting tension spring
There is the second engaging lug.
To increase the rotating range for strutting portion 622, struts the ends bent in portion 622 and be formed in parallel with the folding of fixed link 63
Crimp 623, the second engaging lug are set on bending edges 623.
In use, by the both ends of tension spring difference hook joint on the first engaging lug 631 and the second engaging lug, when spray painting, open
Hydraulic cylinder 61, so that tension spring is stretched, can guarantee that tension spring is sufficiently sprayed onto paint so that strut 62 rotates at this time.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
