Abstract
The invention relates to a spring touch ring welding fixture which comprises a tray used for placement of a corresponding spiral spring, wherein the tray is provided with a locating groove, the head end and the tail end of the spiral spring are clamped in the locating groove, the groove cavity of the locating groove is arc or toroidal, the radius of the groove cavity is equal to that of a prefabricated spring touch ring, and the locating groove is provided with the groove wall used for being in elastic interference fit with the outer circular surface of the spiral spring to enable spring wires at the head end and sprig wires at the tail end of the spiral spring to be fixed in the locating groove. According to the spring touch ring welding fixture, the head end and the tail end of the spiral spring which can be bent into a circle can be located to facilitate welding.
Description
Technical field
The present invention relates to a kind of spring touch finger welding tooling.
Background technology
The electric connection mode in the leading loop of high voltage electric appliance has multiple, wherein advantage such as spring touch finger, good conductivity big with its compact structure, compress variation and have good economic serviceability.The material of spring touch finger is elasticity and metallicity preferred metal line, after metal wire turns to coil spring shape, the hand-held helical spring initial and end two ends of operating personnel, and helical spring curved a circle (spiral elastic ring) shape, another operating personnel weld fixing to the initial and end two ends of spiral elastic ring, helical spring is made into the spring touch finger of a ring-type the most at last.Owing to lack corresponding welding tooling, this just brings a lot of problems, helical spring initial and end two ends need operating personnel to hand the location on the one hand, electric arc and heat energy that welding produces all might injure these operating personnel, also make very low of make efficiency of spring touch finger by the hand-held helical spring way of operating personnel simultaneously; On the other hand, because helical spring spring wire diameter is very little, the gap between the adjacent springs wire ring is very little also, adopts artificial hand-held way to be not easy to control gap between the adjacent springs wire ring, influences welding quality easily.
Summary of the invention
The object of the present invention is to provide a kind of can positioning the helical spring initial and end end of rounding so that the spring touch finger welding tooling that welds.
In order to address the above 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 be used to the helical spring initial and end two ends that are installed, the vallecular cavity of locating slot is shaped as radius circular arc or the annular identical with the radius of prefabricated spring touch finger, and described locating slot has the cell wall that is fixed in locating slot for each the coil spring silk that makes helical spring initial and end two ends with helical spring outer peripheral face elasticity interference fit.
Described pallet is made by the red copper material.
Described pallet has the working face of the described spiral elastic ring of bracketing, convex with two locating pieces that arrange at interval on the working face, circular arc side and external arc side in the opposite flank of two locating pieces is respectively, the working face between inside and outside circular arc side and two the locating pieces described locating slot of having encircled a city.
Also be provided with on the described pallet for made pallet be fixed in clamping limb on the bench vice by corresponding bench vice clamping, 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, helical spring initial and end two ends are installed in the locating slot on pallet, because the vallecular cavity of locating slot is shaped as radius circular arc or the annular identical with the radius of prefabricated spring touch finger, so after helical spring initial and end two ends were installed in the locating slot by technological requirement, helical spring had just been curved one and prefabricated spring touch finger shape annular of the same size; In addition, because the vallecular cavity chamber of locating slot directly is slightly less than helical spring spring external diameter, after in locating slot is packed at helical spring initial and end two ends into, the outer peripheral face of each coil spring silk at helical spring initial and end two ends cooperates with the cell wall elasticity interference roof pressure of locating slot and is fixed in the locating slot, the initial and end end can not flick and become flexible, do not need manually to go helical spring initial and end two ends are positioned, certainly can also stir the adjacent springs wire ring and regulate spacing between the adjacent springs wire ring, to satisfy corresponding welding demand.

The specific embodiment
A kind of embodiment of spring touch finger welding tooling is shown in Fig. 1 ~ 5: comprise pallet 1, the opposing both sides of pallet are respectively arranged with for the clamping limb 4 that is gripped by corresponding bench vice and are used for the corresponding helical spring working face of bracketing, convex with the locating piece 2 that two spacing parallel arrangings arrange on the working face, circular arc side and external arc side in the opposite flank of two locating pieces is respectively, in, working face between external arc side and two locating pieces has been encircled a city and has been used for being installed helical spring head, the locating slot 3 at tail two ends, the vallecular cavity of locating slot is shaped as the radius circular arc identical with the radius of prefabricated spring touch finger 5, the groove of locating slot directly is slightly less than helical spring spring external diameter and makes after helical spring is packed locating slot into the cell wall of locating slot and helical spring head, each coil spring silk outer peripheral face elasticity interference roof pressure at tail two ends cooperates.Clamping limb, pallet and arc locating piece are made by the red copper material, the conduction quality in the time of can helping to weld like this.
During use, by clamping limb is fixed on the bench vice, the adjustment pallet is horizontal, initial and end two ends with spring coil are installed into locating slot then, spring coil is just finished the annular consistent with prefabricated spring touch finger shape automatically, owing to the cell wall of locating slot cooperates with corresponding spring wire outer peripheral face elasticity interference roof pressure the initial and end two ends of spring coil are fixed in the locating slot, can also adjust spacing between the adjacent springs wire ring by stirring the adjacent springs wire ring, to make things convenient for the welding of place, welding position spring wire ring.
In other embodiments of the invention: clamping limb can not have yet, and can directly place pallet on the workbench this moment; Two locating pieces can be respectively cylindricality locating piece and the arc locating piece that is arranged at cylindricality locating piece periphery; Locating piece can not established yet, and this moment, locating slot can be opened in the 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 come the bracketing helical spring; Clamping limb, pallet and arc locating piece also can be made by other metal material, such as iron, aluminium.
