Abstract
The utility model discloses an electrode device, which comprises a column-shaped electrode body. An axially-extending passage is disposed on the electrode body, a movable push rod is inserted in the passage, a radial hole is arranged on the electrode body, an electrode tip is inserted in the radial hole, the bottom of the electrode tip is matched and connected with the front end of the movable push rod through a wedge surface, the movable push rod and the electrode tip are made of conductive metals, and the movable push rod is connected with a welding principal machine. According to the technical scheme, an electrode can be extended to the inside of pipe fitting to reach the position where welding is needed, then the electrode tip is pushed out so that effective pressure can be generated between the upper electrode and the lower electrode and a welded work piece, and then a welding process of the pipe fitting is achieved. The electrode tip is not pushed out until the work piece reaches the welding position so that abrasion caused by the fact that the electrode is extended into the pipe fitting is avoided. After welding loss occurs in the electrode tip, the electrode tip can be replaced independently, and a whole electrode does not need replacing so that maintenance cost is lowered and the cost of an enterprise is lowered.
Description
Technical field
The utility model relates to welding technology field, particularly relates to the employed electrode assembly of a kind of resistance welding equipment.
Background technology
Resistance welded is that welded piece is pressed between two electrodes, and imposes electric current, and utilize electric current to flow through thermal resistance effect that workpiece contact-making surface and adjacent domain produce is heated to workpiece and melts or mecystasis, makes it to form a kind of method that metal combines.As shown in Figure 1, during operation, top electrode 11, bottom electrode 12 must compress workpiece 13,14, produce welding effect through electric current after, at two workpiece 13, form weldering nuclear 15 between 14 and reach the purpose that fuses.When two workpiece are planar materials or when having enough big space mounting upper/lower electrode; Then this method is able to execute work; When workpiece is tube type material; The problem such as strength that compresses that the electrode that is positioned at pipe pipe will take place can't to be provided with, can't to stretch into and can't produce correspondence can't be reached welding procedure.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of the utility model provides a kind of electrode assembly, executes when welding procedure and makes in cast and add man-hour, has the wear to electrodes of minimizing, accurately and fast locatees and produce advantages such as compressing strength between the effective upper/lower electrode.
In order to reach above-mentioned purpose, the technical scheme below the utility model has adopted:
A kind of electrode assembly comprises the cylindrical electrode body, and said electrode body is provided with axially extended passage; Plug movable push bar in this passage; Said electrode body is provided with radial hole, plugs electrode tip in this radial hole, and the electrode tip bottom is connected through wedge surface with the movable push bar front end; Movable push bar and electrode tip are that conducting metal is processed, and movable push bar is connected with the welding main frame.
As preferably, said electrode body is that conducting metal is processed, and the electrode body outside is provided with insulating outer layer.Movable push bar can be connected with welding main frame earth polar through electrode body like this, and can avoid producing the electric current distributary phenomenon when welding.
As preferably, the connecting rod that said movable push bar is processed through insulating materials is connected with the push rod cylinder.
In order to reduce the temperature accumulation that continuous welding causes, as preferably, said electrode body is provided with the chilled(cooling) water return (CWR) device.
As preferably, said electrode tip is the replaceable type electrode tip, when consume takes place, can change.
As preferably, electrode body, electrode tip and movable push bar all use brass, chromium zirconium copper or other of identical component to be applicable to the copper product that electrode uses.
The utility model has been owing to adopted above technical scheme, and compares in the past, can electrode be stretched into pipe fitting inside; Arrival needs the position of welding; Again electrode tip is ejected, make between the workpiece of upper and lower electrode and welding and produce efficient pressure, and then reach the welding procedure of pipe fitting.Electrode tip just upwards ejects the wearing and tearing that caused in the time of can avoiding electrode to stretch into pipe fitting after workpiece arrives the welding position.After the welding loss takes place electrode tip, can change electrode tip separately and need not change whole electrode, thereby reduce maintenance cost and reduced the cost of enterprise.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done a detailed explanation.
Embodiment 1:
Like Fig. 2, Fig. 3, a kind of electrode assembly shown in Figure 4, comprise cylindrical electrode body 1, said electrode body 1 is provided with axially extended passage; Plug movable push bar 2 in this passage; Said electrode body 1 is provided with radial hole, plugs electrode tip 3 in this radial hole, and electrode tip 3 bottoms and movable push bar 2 front ends are connected through wedge surface; Movable push bar 2 is processed for conducting metal with electrode tip 3, and movable push bar 2 is connected with welding main frame 10.
In the present embodiment, said electrode body 1 is processed for conducting metal, and electrode body 1 outside is provided with insulating outer layer 6.The connecting rod 4 that said movable push bar 2 is processed through insulating materials is connected with push rod cylinder 5.Said electrode body 1 is provided with chilled(cooling) water return (CWR) device 9.Said electrode tip 3 is the replaceable type electrode tip.
As shown in Figure 2, when doing, start chilled(cooling) water return (CWR) device 9 and cool off; The pipe that will weld overlaps to electrode body 1 outside and arrives the location, drives push rod cylinder 5, promotes movable push bar 2 via connecting rod 4 and advances; The inclined-plane of movable push bar 2 front ends can upwards eject electrode tip 3, is exerted pressure by the interior side direction pipe fitting of pipe fitting, drives top electrode cylinder 8 again and top electrode 7 is done downwards apply pressure on the workpiece; This moment, upper/lower electrode produced pressure in the workpiece both sides; Start bonding machine main body 10, produce through electric current and between workpiece and melt nuclear, accomplish the pipe fitting welding procedure.After accomplishing welding, involution top electrode cylinder 8 is done top electrode 7 is upwards mentioned, and involution push rod cylinder 5 is done via connecting rod 4 movable push bar 2 is retracted, and electrode tip 3 drops to original position automatically, and can take out the workpiece that welding is accomplished this moment.
It should be noted that; The specific embodiment that provides in the utility model specification only is to the specific descriptions of technical scheme in the invention and non-limiting; For example as shown in Figure 3; The shape of the cross section of the push rod described in the utility model is not limited to the quadrangle form that the utility model adopts, and can also be designed to moulding types of attachment such as triangle or other polygon, and the electrode tip that is upwards ejected also can increase number; Only the utility model technical scheme is done simple change and adopt essence invention spirit of the present invention, still in the protection domain of the utility model.
