Abstract
The invention relates to an electrode support holding rod for point projection welding. The electrode support holding rod comprises a cooling water joint, an electrode support rod, a cooling water pipe, and a bushing, wherein the cooling water joint is arranged at one end of the electrode support rod; the bushing is arranged at the other end of the electrode support rod; the cooling water pipe is located inside the electrode support rod, and is connected with the cooling water joint; the bushing on the electrode support rod prevents the upper diameter of the electrode support rod from being enlarged during the use process due to pressure; as the cooling water pipe inside the electrode support rod is connected with the cooling water joint, the cooling effect is realized by allowing cooling water to enter the electrode support rod. Compared with the prior art, the electrode support holding rod, provided by the invention, has the advantages of stable welding quality, low cost, low repair rate, and the like.
Description
Technical field
The present invention relates to a kind of electrode supporting and hold rod, especially relate to a kind of electrode supporting for a projection welding and hold rod.
Background technology
At present, being permitted the motor support used of multiple projection welding holds rod and exists and be mostly beryllium copper chromium-copper because of material own, cause long-term use and size that cause and electrode contact surface position becomes large, and then affect the stability of welding quality, the stability that have to ensure by strengthening maintenance frequency this size, has increased artificial maintenance cost and waste of material cost.Therefore in a projection welding process, must have corresponding electrode special support to hold rod prevents or reduces electrode and hold excellent large with the change of electrode contact surface position dimension.
Summary of the invention
Object of the present invention is exactly to provide a kind of welding quality stable, cost is low, repair rate the is low electrode supporting for a projection welding to hold rod in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: a kind of electrode supporting for a projection welding is held rod, it is characterized in that, comprise warter connection, electrode support bar, cooling water pipe and edge cover, described electrode support bar one end is provided with warter connection, the other end is provided with edge cover, described cooling water pipe is positioned at electrode support bar inside, and is connected with warter connection;
Electrode supporting is held rod and overlap and prevented that electrode supporting from holding the upper bore of rod in use because pressure-bearing bore becomes greatly by edge, makes cooling water enter electrode supporting hold and in rod, carry out cooling effect at electrode support bar internal cooling water pipe connection warter connection.
Described cooling water pipe joint is provided with water inlet and delivery port, and cooling water pipe connects described water inlet.
In described electrode support bar, angle is matched with using electrode angle, avoids leaking.
The edge cover of electrode supporting club head of the present invention: can play booster action, in use, top electrode on some projection welding welding machine is held the impact that clavate one-tenth is very large and holds the excellent anti-force that is subject to equally itself to supporting the top electrode of top electrode supporting the electrode supporting of bottom electrode in the middle meeting that moves up and down, the change that this edge cover can reduce to hold in impact process excellent bore is greatly large, can hold rod and electrode has good cooling effect to electrode by cooling water pipe simultaneously, ensure normal use and the stability of electric current.
Compared with prior art, the present invention has the following advantages:
One, reduce and reprocess frequency,
Two, ensure stability of the welding quality,
Three, the low maintenance of processing cost is convenient.
Brief description of the drawings
Fig. 1 is that electrode of the present invention is held bar structure schematic diagram.
Shown in number in the figure:
1, edge cover, 2, electrode support bar, 3, warter connection, 4, cooling water pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of electrode supporting for a projection welding is held rod, comprise warter connection 3, electrode support bar 2, cooling water pipe 4 and edge cover 1, described electrode support bar 2 one end are provided with warter connection 3, the other end is provided with edge cover 1, described cooling water pipe 4 is positioned at electrode support bar 2 inside, and is connected with warter connection 3; Described warter connection 3 is provided with water inlet 41 and delivery port 42, and cooling water pipe 4 connects described water inlet 41.
Electrode supporting is held rod and overlap and prevented that electrode supporting from holding the upper bore of rod in use because pressure-bearing bore becomes large by edge, makes cooling water enter electrode supporting hold and in rod, carry out cooling effect at electrode support bar inside connection warter connection.
Electrode supporting of the present invention is held rod, to overlap 1 by edge to be enclosed within electrode support bar 2 bore and to prevent on electric support stick 2 that bore is in use because pressure-bearing bore becomes large outward, warter connection 3 is connected to 2 times bores of electrode support bar, cooling water pipe 4 ensures that at inner warter connection 3 water inlets that connect of electrode support bar 2 cooling water enters electrode and holds in rod, then pass through delivery port, cooling water flow out of, form good cooling effect; The interior angle of electrode support bar 2 and the angle automatching that is used electrode, water-tight in ensureing to use.
