Description
Technical field
The present invention relates to a kind of wire casing grounding screw special welding guns.
Background technology
It is found in the maintenance process of rail vehicle, wire casing does not have effective grounding on some vehicles, and there are larger safety winds
Danger, it is therefore desirable to the welding of grounding screw is carried out to wire casing on vehicle.That there are sparks is big for common welding manner, welding deformation is big lacks
It falls into, therefore can only use welding deformation is small to be welded with the small stud welding machine of spark.Since the position that wire casing is onboard installed is empty
Between it is narrow, the welding space of earth stud only has 75mm.And according to result of calculation, to ensure effectively welding, the length of ignition tip
Degree cannot be less than 15mm, therefore the accessories such as the installation of the guiding of welding gun, conducting wire, resetting spring, welding positioning, ignition tip locking device
Assembled dimension no more than 60mm.However existing stud welding gun has that the body of a gun is long in the market, can not complete
The welding of wire casing grounding screw operates.
Invention content
The technical problem to be solved in the present invention is to provide a kind of compact-sized wire casing grounding screw special welding guns.
Technical solution of the invention is：The wire casing grounding screw special welding gun provided, including handle and pipette tips,
It is characterized in that：The pipette tips include ignition tip, insulating sleeve and guide rod；Guide rod coaxial arrangement in insulating sleeve,
The ignition tip is installed on guide rod.One part of insulating sleeve just assumes responsibility for positioning, is oriented to, the function of arc extinguishing, and structure is tight
It gathers, size is small, is suitable for the welding of the wire casing grounding screw of narrow space.
The other end of above-mentioned guide rod installs fastening bolt, for the fixed conducting wire drawn.
One end of above-mentioned guide rod installation ignition tip is hollow tubular, installs ignition tip inside hollow pipe, outside hollow pipe with
Clamp nut is installed, clamp nut may be implemented to be oriented to and substrate hold-down function, structure are compacter between insulating sleeve.
The spring being axially arranged is installed, the compression for ignition tip resets between above-mentioned guide rod and insulating sleeve.
Fixed ring is installed, the fixed ring is installed on handle, is convenient for handle and insulation sleeve outside above-mentioned insulating sleeve
The separate machined of pipe.
Above-mentioned handle is "u"-shaped, including " L " shape holder and " L " shape handle；Holder one end installation
Pipette tips, the other end of holder are connected with the inflection point of the handle；The handle can be rotated around inflection point.Vertical by common welding gun adds
Pressure changes into gripping pressurization.
Beneficial effects of the present invention：
(1) by the way that insulating sleeve is arranged positioning, the function being oriented to may be implemented, not only instead of common pipette tips in the present invention
In positioning three-jaw, three parts of guide ring and insulation sleeve, it is compact-sized, reduce pipette tips size, at the same time also add
The function of arc extinguishing.
(2) conducting wire is directly installed on one end of ignition tip mounting base by the present invention, and guiding when ignition tip compresses is by compressing
The outer circle of nut is realized, will be oriented to and substrate hold-down function is integrated on one part, can make the structure compacter.
(3) present invention produces the handle of U-shaped folder structure according to the construction features of wire casing.Vertical by common welding gun adds
Pressure mode changes into gripping pressuring method, can not only meet the requirement of pressing force, and easy to operate.
Description of the drawings
Fig. 1 is the pipette tips structural schematic diagram of present pre-ferred embodiments；
Fig. 2 is the B-B cross section views of pipette tips in Fig. 1；
Fig. 3 is the welding gun overall structure diagram of present pre-ferred embodiments.
Specific implementation mode
Referring to Fig. 1 and Fig. 2, the pipette tips structure of present pre-ferred embodiments includes ignition tip 2, insulating sleeve 1 and guide rod 3.
Guide rod 3 is coaxially disposed in insulating sleeve 1, and ignition tip 2 is installed on 3 one end of guide rod.Insulating sleeve 1 assumes responsibility for positioning, is oriented to, goes out
The function of arc positions the function of three three-jaw, guide ring and insulation sleeve parts instead of common pipette tips, while increasing arc extinguishing
Function.The pipette tips of the present embodiment have compact-sized, the small feature of size, are suitable for the wire casing grounding screw of narrow space
Welding.
In order to further reduce pipette tips size, one end that guide rod 3 is installed to ignition tip in the present embodiment is set as hollow pipe
Ignition tip 2 is installed in shape, hollow pipe inside, is equipped with clamp nut 4, ignition tip compression outside hollow pipe between insulating sleeve 1
When guiding realized by the outer circle of clamp nut, will be oriented to and substrate hold-down function be integrated on one part.Conducting wire is then directly pacified
Mounted in the other end of guide rod, it is fixed by fastening bolt 6.The spring being axially arranged is installed between guide rod 3 and insulating sleeve 1
5, the compression for ignition tip 2 resets.
Since handle is usually metal material, with insulating sleeve usually can not one-pass molding, therefore in the outer of insulating sleeve 1
Fixed ring 7 is installed in portion, and fixed ring 7 is fixed on by underlying mounting hole 8 on handle, convenient for point of handle and insulating sleeve
Processing is opened, while the replacement for being also convenient for handle uses.
Stud welding machine is at work, it is desirable that welding screw at least has 20~30kg in the moment of welding machine discharge and is directed toward base material
Pressing force；But since space limits, original press-down type operation cannot achieve, and welding gun mode of operation is also required to change.Referring to
Fig. 3, the present embodiment design the handle of U-shaped folder structure according to the construction features of wire casing, which includes 9 He of " L " shape holder
One " L " shape handle 10；Pipette tips are installed in 9 one end of holder, and the other end of holder 9 is connected with the inflection point of institute handle 10；Handle 10
Pin 11 is set at inflection point so that handle can be rotated around its inflection point.It is provided with switch 12 on the arm of the installation pipette tips of holder 9, is switched
12 outside is equipped with arc protective cover 13, prevents the appearance of maloperation.
When being subjected to, the U-shaped handle of the present embodiment is clamped on online slot, operating personnel hold and press and hold
10 and 9 equitant arm of holder so that handle 10 rotates inwardly.Another arm of handle 10 is close to wire casing lower edge, operation
The curable grip that personnel apply is converted into the pressure at right angle between the arm of handle and pipette tips, can not only meet the requirement of pressing force,
And it is easy to operate.When therefore solving using common welding gun, the problem of limited by space and pipette tips can not be pushed.
Using welding gun provided by the invention, without being dismounted to wire casing, directly onboard wire casing can be connect
The welding of ground stud, is greatly saved the cost of overhaul, improves manufacturing schedule, can greatly shorten the time between overhauls(TBO), alleviates car
The problem of inspection rack position anxiety.In addition to this, the maintenance expense brought because dismounting wire casing and inter process transport can also be saved
Expense further reduced the cost of overhaul.
