Abstract
The utility model relates to a welding fixture for the bottom of a fire extinguisher cylinder, which is characterized by being provided with a positioning sleeve. The length and the diameter of the positioning sleeve match with those of the fire extinguisher cylinder to be processed, one end of the positioning sleeve is provided with a bearing seat capable of moving axially along the positioning sleeve, the upper surface of the bearing seat is provided with an arc recess matching the bottom of the fire extinguisher cylinder in shape, and the other end of the positioning sleeve is provided with an openable hoop. The welding fixture is applicable to mass production and convenient to operate, and has the advantages of capability of correcting ovality of the cylinder so that the cylinder is proper to match, easiness in radiation, difficulty in bonding and flashing of welding flatter, easiness in cleaning and the like.
Description
Technical field
The utility model relates to a kind of welding tooling, relates in particular to a kind of fire extinguisher cylindrical shell bottom welding tooling.
Background technology
The cylindrical shell of the dry powder extinguisher that we use always, foam annihilator (aqua type) is made up of bottleneck, stack shell and bottom, and stack shell and bottom all are to be stretched by the carbon steel steel plate to form, and wall thickness is generally 0.8mm-2mm.Because wall thickness is thinner, carbon dioxide gas arc welding is adopted in stack shell and bottom.In order to adapt to batch process, welding method is taked Lincoln weld.Conventional welding tooling such as Fig. 1 are made up of positioning sleeve 11 and collet 12, and material is ordinary carbon steel, and is simple in structure.When having enough to meet the need, the process neutralization department produces slight deformation owing to cylindrical shell in the practical operation, certain ovality appears in cylindrical shell, this will have a strong impact on welding quality, and product the weld seam scrap (bridge) occurs and reinforcement is irregular, cylindrical shell has gas leak phenomenon (lack of penetration), cylindrical shell has the phenomenon of burning quality problems such as (burning).For the ease of operation, there is 0.5mm-1mm in the gap between conventional welding tooling and the cylindrical shell, therefore can't eliminate because the problems of welded quality that the ovality of cylindrical shell produces; Because the frock material all is carbon steel, the welding slag that produces during welding, splashing is bonded on the frock easily, not easy to clean; In addition, the positioning sleeve 11 of frock is whole, is difficult for heat radiation.
Summary of the invention
The utility model main purpose is: provide a kind of fire extinguisher cylindrical shell bottom welding tooling, to improve the welding quality of product.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of fire extinguisher cylindrical shell bottom welding tooling, it is characterized in that: have positioning sleeve, the length of positioning sleeve and diameter and the fire extinguisher cylindrical shell that needs to process adapt, one end of described positioning sleeve is provided with can be along the axially movable lining seat of location interplanting, be provided with the circular arc pit above the described lining seat, the shape of its pit and fire extinguisher cylindrical shell bottom adapts, the other end of described positioning sleeve be equipped with can folding anchor ear.
The technical solution of the utility model can also be further perfect:
As preferably, described anchor ear is divided into clips that is connected on the positioning sleeve and the activity hoop that is connected with clips, one end of described movable hoop adopts hinge to be connected with an end of clips by otic placode, and the other end of movable hoop and the other end of clips unblank to link to connect with one soon.
As preferably, be lined with brass bushing in the described anchor ear.
As preferably, on positioning sleeve, have two to three axial long holes, described slotted hole is arranged on the position that positioning sleeve is connected with the lining seat; Be provided with screw on the lining seat, described screw is arranged on and the corresponding position of slotted hole, is connected and fixed with bolt between described slotted hole and screw.
The beneficial effects of the utility model are: are suitable for and produce in batches, and easy to operate; Have the ovality that to proofread and correct cylindrical shell simultaneously, it is cooperated suit, easily heat radiation, welding slag, the advantages such as being difficult for bonding, easy cleaning of splashing.

The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Fire extinguisher cylindrical shell bottom welding tooling as shown in Figure 2, have positioning sleeve 4, be provided with adjustable lining seat 5 in the described positioning sleeve 4, on the described positioning sleeve 4 two slotted holes are set, described positioning sleeve 4 and lining seat 5 are fixing by bolt 6, can move and regulate along slotted hole direction (drum shaft to).One of described positioning sleeve 5 hold level with both hands be divided into two anchor ear 2(and see Fig. 4), add lining ring 1 in the described anchor ear, material is H62.Described anchor ear 2 one ends connect by otic placode 8, bearing pin 7, and anchor ear 2 can freely rotate around bearing pin 7.Described anchor ear 2 other ends connect one and unblank to detain 3 soon, describedly unblank to detain 3 soon and can realize opening fast and locking fast.
During operation, welding tooling is installed as Fig. 5.Positioning sleeve 4 is fixed on the seat in the plane 10 of automatic submerged arc welding machine, anchor ear 2 unclamps (see figure 3), and cylindrical shell 9 is put into positioning sleeve 4, and locking unblanks to detain 3 soon, and anchor ear 2 closes up.Adjusting welding torch position just can weld.
