Abstract
The present invention relates to a kind of spring touch finger welding tooling, comprise for placing corresponding helical spring pallet, pallet is provided with the locating slot for the helical spring initial and end two ends that are installed, the vallecular cavity shape of locating slot is circular arc or annular that radius is identical with the radius of prefabricated spring touch finger, and described locating slot has for making each coil spring silk at helical spring initial and end two ends be fixed on cell wall in locating slot with helical spring outer peripheral face elasticity interference fit.The invention provides a kind of can positioning so that the spring touch finger welding tooling welded the helical spring initial and end end of rounding.
Description
Technical field
The present invention relates to a kind of spring touch finger welding tooling.
Background technology
The electric connection mode that high voltage electric appliance dominates loop has multiple, wherein the advantage such as spring touch finger, good conductivity large with its compact structure, compress variation and have good economic serviceability.The material of spring touch finger is elasticity and the good metal wire of metallicity, after metal wire turns to coil spring shape, the hand-held helical spring initial and end two ends of operating personnel, and helical spring is curved circle (spiral elastic ring) shape, the initial and end two ends of another operating personnel to spiral elastic ring are welded and fixed, and helical spring is made into the spring touch finger of a ring-type the most at last.Owing to lacking corresponding welding tooling, this just brings a lot of problems, helical spring initial and end two ends need operating personnel to come hand-held location on the one hand, the electric arc that welding produces and heat energy all likely injure these operating personnel, also make the make efficiency of spring touch finger very low by the hand-held helical spring way of operating personnel simultaneously; On the other hand, because helical spring wire diameter is very little, also very little of the gap between adjacent springs wire ring, adopts manually hand-held way to be not easy to control the gap between adjacent springs wire ring, easily affects welding quality.
Summary of the invention
The object of the present invention is to provide a kind of can positioning so that the spring touch finger welding tooling welded the helical spring initial and end end of rounding.
In order to solve the problem, technical scheme of the present invention is:
A kind of spring touch finger welding tooling, comprise for placing corresponding helical spring pallet, pallet is provided with the locating slot for the helical spring initial and end two ends that are installed, the vallecular cavity shape of locating slot is circular arc or annular that radius is identical with the radius of prefabricated spring touch finger, and described locating slot has for making each coil spring silk at helical spring initial and end two ends be fixed on cell wall in locating slot with helical spring outer peripheral face elasticity interference fit.
Described pallet is made up of red copper material.
Described pallet has the working face of spiral elastic ring described in bracketing, working face is convexly equipped with two spaced locating pieces, the opposite flank of two locating pieces is respectively Inner arc side and external arc side, and the working face between inside and outside circular arc side and two locating pieces has been encircled a city described locating slot.
Described pallet is also provided with and makes for being clamped by corresponding bench vice pallet be fixed on clamping limb on bench vice, described clamping limb and locating slot are arranged at the opposing both sides of described pallet.
Beneficial effect of the present invention is: during use, in the locating slot that helical spring initial and end two ends are installed on pallet, vallecular cavity shape due to locating slot is the circular arc or annular that radius is identical with the radius of prefabricated spring touch finger, so when helical spring initial and end two ends are installed on after in locating slot by technological requirement, helical spring has just been curved an annular consistent with prefabricated spring touch finger shape size; In addition, because the footpath, vallecular cavity chamber of locating slot is slightly less than helical spring spring outer diameter, load after in locating slot at helical spring initial and end two ends, the outer peripheral face of each coil spring silk at helical spring initial and end two ends and the cell wall elasticity interference top press-fit of locating slot and be fixed in locating slot, initial and end end can not flick and loosen, do not need manually to go to position helical spring initial and end two ends, certainly can also stir adjacent springs wire ring to regulate the spacing between adjacent springs wire ring, weld demand accordingly to meet.

Detailed description of the invention
A kind of embodiment of spring touch finger welding tooling is as shown in Fig. 1 ~ 5: comprise pallet 1, the opposing both sides of pallet are respectively arranged with clamping limb 4 for being gripped by corresponding bench vice and for the corresponding helical spring working face of bracketing, working face is convexly equipped with the locating piece 2 that two spacing parallel arrangings are arranged, the opposite flank of two locating pieces is respectively Inner arc side and external arc side, in, working face between external arc side and two locating pieces has been encircled a city for the helical spring head that is installed, the locating slot 3 at tail two ends, the vallecular cavity shape of locating slot is the circular arc that radius is identical with the radius of prefabricated spring touch finger 5, the groove footpath of locating slot is slightly less than helical spring spring outer diameter and makes after helical spring loads locating slot, the cell wall of locating slot and helical spring head, each coil spring silk outer peripheral face elasticity interference top press-fit at tail two ends.Clamping limb, pallet and arc locating piece are made by red copper material, can contribute to conductive qualities when welding like this.
During use, by clamping limb is fixed on bench vice, adjustment pallet is horizontal, then the initial and end two ends of spring coil are installed into locating slot, spring coil is just completed the annular consistent with prefabricated spring touch finger shape automatically, because the cell wall of locating slot makes the initial and end two ends of spring coil be fixed in locating slot with corresponding spring wire outer peripheral face elasticity interference top press-fit, spacing between adjacent springs wire ring can also be adjusted, to facilitate the welding of welding position place spring wire ring by stirring adjacent springs wire ring.
In other embodiments of the invention: clamping limb can not have yet, now can directly pallet be placed on a workbench; Two locating pieces can be respectively cylindricality locating piece and be arranged at the arc locating piece of cylindricality locating piece periphery; Locating piece also can not be established, and now locating slot can be opened in pallet, and locating slot can be an annular groove, when the circumferential lengths of locating slot is longer, can directly utilize the bottom land of locating slot to carry out bracketing helical spring; Clamping limb, pallet and arc locating piece also can be made up of other metal material, such as iron, aluminium.
