Abstract

The utility model discloses a draw plate holder utensil of putting off arc that is used for carbon steel or stainless steel makeup, include: bottom bracket, two top splint and two sets of pretension formula bolt groups, the bottom bracket be the V style of calligraphy, two top splint pass through pretension formula bolt component do not fix the both sides opening part of bottom bracket. The utility model discloses anchor clamps during operation, bottom bracket and top face board are with the mother metal and draw the plate holder of putting off arc and live, and nut through screwing up pretension formula bolt group is with the mother metal and draw the board fastening of putting off arc, need not to adopt the electric welding mode with the mother metal and draw that to put off arc the board fixed. Therefore can avoid electrically welding the damage to the mother metal groove, can reduce the electric welding and the work load of polishing simultaneously, can practice thrift man -hour, and save material improves product quality simultaneously.

Description

A kind ofly draw arc-extinguishing plate fixture for carbon steel or stainless steel jigsaw
Technical field
The utility model belongs to boats and ships and manufacture of steel structure technical field, is specifically related to a kind ofly draw arc-extinguishing plate fixture for carbon steel or stainless steel jigsaw.
Background technology
When carbon steel or stainless steel jigsaw, easily produce weld defect due to during welding in striking or blow-out place, do not allow striking and blow-out in mother metal weld seam.For ensureing welding quality, need to add at weld seam two ends to draw arc-extinguishing plate.Current operation is welded on mother metal end of welding bead by drawing arc-extinguishing plate, will draw arc-extinguishing plate and cut off after having welded, end polishing fairing.The arc-extinguishing plate that draws for carbon steel cuts off, and common oxy-acetylene cutter can operate; Arc-extinguishing plate is drawn for stainless steel, then needs special cutting equipment, or remove with grinding-wheel grinder.Thus, following drawback will be brought:
(1), mother metal groove is destroyed.Mother metal end generally all has groove, when drawing arc-extinguishing plate welding and getting on, mother metal groove can be destroyed, reduce follow-up welding quality.
(2), man-hour is wasted.Arc-extinguishing plate is drawn in each assembling, all needs to be welded on drawing arc-extinguishing plate on mother metal.Also to cut off drawing arc-extinguishing plate after completion, polishing is repaired to the mother metal damaged.Especially arc-extinguishing plate is drawn for stainless steel, use the mode inefficiency that grinding-wheel grinder removes.
(3), material is wasted.Due to the not reproducible utilization of wlding, welding is drawn arc-extinguishing plate and is needed to waste wlding.Then very large to the consumption of grinding wheel except drawing arc-extinguishing plate with grinding-wheel grinder.
Summary of the invention
For the drawback of drawing arc-extinguishing plate assembling mode at present, the purpose of this utility model is to provide a kind of and draws arc-extinguishing plate fixture for carbon steel or stainless steel jigsaw, its assembling and remove convenient, is easy to operation, saves material, save man-hour.
Technical solution of the present utility model is as follows:
Draw an arc-extinguishing plate fixture for carbon steel or stainless steel jigsaw, its feature is, comprising: bottom bracket, two pieces of top clamping plate and two cover prefastening bolt groups;
Described bottom bracket is V-shape, and two pieces of described top clamping plate are separately fixed at the both-side opening place of described bottom bracket by described prefastening bolt group.
Described bottom bracket is V-shape, can alleviate the weight of this fixture on the one hand, takes conveniently.On the other hand when striking or blow-out, weld seam is positioned at the openwork part of V-shaped, can not cause drawing arc-extinguishing plate and glue with bottom bracket.
Described top clamping plate are horizontal L-type, and its short end is provided with through hole, and for through bolt, top clamping plate can turn to suitable angle along perforate and fixedly draw arc-extinguishing plate.What long end went for plurality of specifications draws arc-extinguishing plate, adds the flexibility of this fixture.
The described prefastening bolt group described in prefastening bolt group comprises screw rod and the nut that is set on this screw rod and short spring.Nut inside has convex shoulder, for fixing short spring.Due to the existence of short spring, top clamping plate can be clamped with certain pretension and draw arc-extinguishing plate, tightening nuts of need not too exerting oneself like this can be fixed drawing arc-extinguishing plate.
The beneficial effects of the utility model are:
1) draw arc-extinguishing plate by this Fixture assembly, avoid and draw welding of arc-extinguishing plate and mother metal, protect mother metal groove.
2) to remove when drawing arc-extinguishing plate without the need to cut off or worn, decrease the workload of polishing.
3) tool makes simple, uses light, can reuse, effectively can reduce man-hour, reduces material consumption.

Fig. 2 is the structural representation of bottom bracket in the utility model.
Fig. 3 is the structural representation of top clamping plate in the utility model.
Fig. 4 is the structural representation of prefastening bolt group in the utility model.
Fig. 5 is nut structure schematic diagram in prefastening bolt group.
Fig. 6 is the using state figure that draw arc-extinguishing plate fixture of the utility model for carbon steel or stainless steel jigsaw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, is easier to understand advantage of the present utility model and function.
Please first consult Fig. 1-2, as shown in the figure, a kind ofly draw arc-extinguishing plate fixture for carbon steel or stainless steel jigsaw, comprising: bottom bracket 1, top clamping plate 2 and prefastening bolt group 3.Described bottom bracket is V-shape, totally two pieces, described top clamping plate, in horizontal L-type, being positioned at two of V-shaped bottom bracket supports above legs, described prefastening bolt group is made up of screw rod 3-1, nut 3-2, short spring 3-3 tri-part, through in the perforate of described bottom bracket and described top clamping plate.Wherein nut inside has convex shoulder 3-4, and for withstanding short spring, short spring provides certain pretightning force will to draw arc-extinguishing plate and mother metal is fixed to facilitate.
When using this Fixture assembly to draw arc-extinguishing plate, first the nut of this fixture is unscrewed, bottom bracket is placed in below mother metal 4, top clamping plate are placed on above mother metal, to draw arc-extinguishing plate 5 is placed in the middle of bottom bracket and top clamping plate, tightening nuts, will draw arc-extinguishing plate and mother metal end of welding bead is clamped fixing, can carry out weld seam welding.After having welded, unscrew nut, this fixture unclamped and removes, arc-extinguishing plate will be drawn and to cut off or worn, commissure polishing along.
