Description
Technical field
This utility model relates to the auxiliary device of a kind of welders training examination, particularly relates to a kind of welders training examination and uses
Argon arc welding back side argon protective device.
Background technology
When using the chemical element Active Metals such as argon arc welding soldering stainless steel or titanium alloy, due to welding base metal and the parent of oxygen
Very big with power, if not taking weld seam protection measure, the weld metal at the back side is easy in welding process oxidation, causes alloy
Melting loss of elements, easily produces weld defect, causes the mechanical property of weld metal and corrosion resistance to decline.Take an examination at welders training
In, it is also required to carry out back side argon shield, the welding quality of guarantee back of weld when argon arc welding is used for this type of material.
Welders training examination uses special operation support, including column and the Rotatable bracket on top, and will training
The plate-like piece of instruction examination or tube-like piece are fixed on operation support and are convenient for welding operation.But at present for the needs back side
The argon arc welding operation of argon shield does not also have special device, had a strong impact on welding student's learning effect in this project and
The performance of practical level during examination.
Summary of the invention
This utility model provides a kind of welders training examination argon arc welding back side argon protective device, can be in training examination
In time plate-like piece and tube-like piece are carried out argon arc welding fillet welding for fixing weldment and providing backing run to protect, the actual application of simulated field
State, beneficially student quickly grasp argon arc welding welding skill when training, play real weld horizontal in examination.
In order to achieve the above object, this utility model realizes by the following technical solutions:
A kind of welders training examination argon arc welding back side argon protective device, it is adaptable to plate-like piece welds with tube-like piece fillet welding
Connect；Including gripper shoe, base, breather and presser device；Described base is vertical with gripper shoe to be fixed, and sets ventilation bottom gripper shoe
Pipe, connection base inner space, breather one end, the other end connects outside argon conveyer device；Divide in the gripper shoe of base both sides
Not setting presser device for fixing plate-like piece, tube-like piece is sleeved on outside base or is erected at above base by plate-like piece.
Described presser device is made up of bolt and pressing plate, and bolt is arranged on pressing plate side, and bolt head and gripper shoe are opened
If bolt hole coordinate fixing, pressing plate can rotate around bolt.
Compared with prior art, the beneficial effects of the utility model are:
For fixing weldment and providing the back of the body when 1, plate-like piece and tube-like piece can be carried out argon arc welding fillet welding in training examination
Weldering protection, simulated field realistic application conditions, beneficially student quickly grasp argon arc welding welding skill when training, in examination
Play real weld horizontal；
2) simple in construction, makes, installs, easy to use, low cost of manufacture.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 2, be structural representation of the present utility model, a kind of welders training examination argon described in the utility model
Arc-welding back side argon protective device, it is adaptable to plate-like piece 6 welds with tube-like piece 7 fillet welding；Including gripper shoe 1, base 2, breather 3
And presser device；Described base 2 is vertical with gripper shoe 1 to be fixed, and sets breather 3, breather 3 one end communicating pipe bottom gripper shoe 1
Seat 2 inner spaces, the other end connects outside argon conveyer device；Set respectively in the gripper shoe 1 of base 2 both sides presser device for
Fixing plate-like piece 6, tube-like piece 7 is sleeved on outside base 2 or is erected at above base 2 by plate-like piece 1.
Described presser device is made up of bolt 5 and pressing plate 4, and bolt 5 is arranged on pressing plate 4 side, bolt 5 head and gripper shoe
The bolt hole offered on 1 coordinates fixing, and pressing plate 4 can rotate around bolt 5.
The using method of a kind of welders training examination argon arc welding back side described in the utility model argon protective device is as follows:
During training examination, first the gripper shoe 1 of the argon arc welding back side described in the utility model argon protective device is fixed on weldering
On the operation support that work training examination is special, upward, breather 3 side is down in base 2 side；By breather 3 and outside argon
Conveyer device connects, and plate-like piece 6 and tube-like piece 7 spot welding is fixed, and plate-like piece 6 both sides are fixed on gripper shoe 1 by presser device
Top.When tube-like piece 7 diameter is less than base 2 diameter, tube-like piece 7 is fixed on after being directed at base 2 above base 2 (such as Fig. 3-Fig. 4
Shown in), when tube-like piece 7 diameter is more than base 2 diameter, tube-like piece 7 is sleeved on outside base 2 (as shown in Fig. 5-Fig. 6).Welding
Operation mainly completes the fillet welding of tube-like piece 7 and plate-like piece 6 junction, and angle welding 8 is full penetration weld.First by tube-like piece before welding
7 top seals, prevent argon leakage in welding process, first open argon conveying switch applying argon gas in tube-like piece 7, then use argon
Arc welding equipment welding；In welding process, the back side of angle welding 8 is among argon atmosphere protection all the time, thus prevents because not carrying on the back
The weld defect that face argon shield is caused produces.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality
Novel technical scheme and conceive equivalent or change in addition, all should contain within protection domain of the present utility model.
