Description
Technical field
The present invention relates to arc welding torch field, specifically, is a kind of V-arrangement nail arc welding torch.
Background technology
Arc welding is a kind of relatively common electric welding mode in welding, and arc welding gun includes gun body, plug and fixture, is welded
Need to change when connecing the fixture of different-diameter to adapt to various electrode dimensions, operation is cumbersome, and its fixture mouth is mostly cylinder
Shape, can only weld the welding rod of given shape.
Need to weld on the fin of water-cooling wall of power boiler substantial amounts of V-arrangement nail to increase intensity, V-arrangement nail need to be put during welding
On welding position, then with nickel-base welding rod by V-arrangement nail welding boiler water wall, during electric welding, employee work intensity is big, is welded into
This height.
The content of the invention
To solve the above problems, the invention provides a kind of V-arrangement nail arc welding torch, the various types of V of its adaptation
Staple is welded, the labor intensity of employee when mitigating electric welding, reduces welding cost.
The technical solution used in the present invention is：A kind of V-arrangement follows closely arc welding torch, including welding gun body, plug, fixture, described
Plug two ends connect the gun body and the fixture respectively, and the fixture is flat bulk, including long block and short block, the long block
Upper end is fixedly connected with the plug, and the short block is provided with corresponding hole with the long block, and the short block upper end is by wearing
The screw and matching nut and the long block for crossing the hole is connected, and leaves sky between the short block lower end and the long block lower end
Gap, the distance in the space are the diameter of minimum V-arrangement nail, are provided with shell fragment between the screw and the short block.
Further improve, between the short block and the long block, two wall of space is provided with horizontal dentation ripple, steps up pin more
Firmly.
The fixture reserves certain clamping force, when between the short block and the long block by the way of spring clamp
When gap snaps in different types of V-arrangement pin, the short block outwards applies thrust, and the shell fragment inwardly applies pressure and pin is entered
Row is clamped.The fixture plays general effect, adapts to any kind of pin, improve production efficiency；The short block and the length
The gap that block is formed is provided with transverse wave, increases frictional force, and grip force is higher.
The main body of arc welding torch is solenoid and spring structure, during welding, height that pin lifts, is sent
Lower depth, lift speed and send lower speed to be important 4 parameter, for welding process and welding quality have larger shadow
Ring；What pin was moved realizes the compression of power on/off and spring mainly by coil, discharges to complete, the knot of arc welding torch itself
The characteristics of structure determines regulation and performance, the action completed by arc welding is：Precompressed-lift striking-keep-send down.
In prior art, arc stud welding welding gun includes solenoid, spring structure, fixed core and dynamic iron core, described dynamic
The gap reserved between unshakable in one's determination and fixed core, the arc stud welding welding gun clamping stud pin is placed on workpiece to be carried out vertically in advance
Pressure, has controlled arc-height according to the spring-compressed distance inside band steel thickness and stud pin size adjustment welding gun, has typically set
Put 2～3mm of spring-compressed distances and arrive spacing.During welding, arc welding gun switch is pulled, the solenoid in welding gun is powered so that plug
Motion upwards is produced, stud pin also lifts certain altitude therewith, at the same time, connect the source of welding current, stud pin and work
The starting the arc in the presence of welding current between part；Stud pin is lifting height and position holding for a period of time, and electric arc fully burns,
Welding pool is formed on workpiece；Welding Preset Time is arrived, solenoid power-off, in spring force and plug self gravitation effect,
Under, stud pin send down to molten bath and completes welding.
The defect that the arc welding torch of prior art is present is：
1. the height for lifting of stud pin determined by the gap reserved between dynamic unshakable in one's determination and fixed core, and stud pin send
Spring precompressed length when lower depth is then started by welding determines that the setting of the two parameters is typically according to different Welders
Skill, by adjusting what welding gun was realized manually before welding starts, generally regulation numerical value is not accurate enough, and wastes time and energy.
2. suitable stud pin lift speed ensure that normally igniting for welding arc, welding gun lift after generation drawing
Arc is too short or long can all affect welding quality, it is desirable to keep stable arc length；And send lower speed to affect weldering to a certain extent
The formation quality of joint, send the too fast molten pool metal that easily produces of lower speed to splash, send the too slow then stud pin of lower speed to enter
The impulse force in molten bath is reduced, inadequate to molten pool metal extruding, affects welding quality.During welding, the angle of welding gun, stability are difficult to handle
Hold, easily produce electromagnetism and blow partially, electric arc is unstable, or completely not molten phenomenon.
The present invention can solve the above problems, and the present invention is further improved by, and the V-arrangement nail arc welding torch also includes
Clip, guide rail, bakelite plate, support bar, in the gun body, the guide rail is parallel with the gun body for the hoop sleeve, its top
It is screwed on the clip, the lower end of the guide rail and the plug passes through the bakelite plate, sets on the guide rail
There are screw thread and two matching nuts, goddess of lightning's plate is fixed on centre, the support bar and the guide rail by described two nuts
Parallel, the upper end of the support bar passes through the bakelite plate.
The bakelite plate is enclosed within the guide rail and the plug, and goddess of lightning's plate can slide up and down regulation and institute along guide rail
The distance between fixture is stated, is fixed by the screw thread and matching nut on the guide rail, can more intuitively by adjusting bakelite
The distance between plate and fixture control different type V-arrangement pin and the distance on band steel surface, control an initially arc-height, carry out micro-
Adjust；The they sup-port is on weldment, it is ensured that the spirit of the stability and angle adjustment of V-arrangement nail arc welding torch during welding
Activity, prevents unstable electric arc, inclined arc, completely molten etc. phenomenon, shaping that V-arrangement pin welds can be better controled over
And quality, reach more preferable welding effect.
Further improve, the guide rail is two, and the support bar is one, support as a face, more convenient adjustment welding
Angle, the support bar are insulant, it is ensured that the safety of employee's operation.
Further improve, the clip is provided with locking position, the locking position is provided with screwed hole, by through the spiral shell
The locking member of pit is fixed in the gun body；The screwed hole can be horizontal tapped through hole, the locking member be with
The screw and nut of set, which passes through the locking position, or the screwed hole perpendicular to the gun body, and the locking member is spiral shell
Silk, which passes through the locking position to withstand gun body.
When V-arrangement nail is welded, due to the position during welding, the change of angle, be inconvenient to sometimes rotate the V-arrangement nail
Arc welding torch, then just can unclamp the locking member of the clip, the clip is rotated, and the guide rail drives the bakelite
Plate is rotated, and then drives the support bar to rotate, and support bar is adjusted to the position of suitable support, and then tightens the tight lock part
The clip is fixed by part.
Beneficial effects of the present invention are：Simple structure, it is easy to operate, make welding reach semi-automatic degree, save weldering
Material cost, greatly alleviates the labor intensity of employee, improves circumstance, improves work efficiency and welding quality,
The cost performance of enterprise product is enhanced, enterprise's competitive advantage in industry is improved.
