Abstract
The utility model discloses a kind of lengthening stud gun, it comprises stud gun mouth, lengthening joint, pin chuck and stud gun body, it is characterized in that the pin length that lengthening joint between stud gun mouth and stud gun body and pin chuck can be installed needed for us and change its length, making it can weld the pin of various different length.
Description
Technical field
The utility model relates to a kind of stud gun welding pin, particularly relates to a kind of stud gun that can be used for different length pin.
Background technology
In boiler industry, on membrane wall steel pipe in water-cooling system parts, design often can weld the pin of various different size length according to demand in its surface design, and there is certain length range requirement in stud gun manufacturing firm to beaten pin length on market, but some is required to the pin of lengthening according to boiler design, then the stud gun of common manufacturer production does not just weld, this lengthening stud gun of our design improvement for this reason, its serviceability is stablized, efficiency is high, structure is simple, easy to operate, can to various different size, the pin of length welds, and be firmly connected on tube wall.
Summary of the invention
The purpose of this utility model is to provide a kind of stud gun that can weld various extended type length pin.
The utility model is achieved like this.A kind of lengthening stud gun, it comprises stud gun mouth, lengthening joint, pin chuck and stud gun body, it is characterized in that installing lengthening joint between stud gun mouth and stud gun body, pin chuck is positioned at lengthening joint, and one end of pin chuck is arranged on stud gun body.
The length of described lengthening joint changes along with the length variations of pin.
The length of described pin chuck changes along with the length variations of pin.
Described lengthening joint adopts two to be internal and external threads connected mode, male end connecting pin nail gun body, female end connecting pin nail gun mouth.
Described lengthening joint leaves two kidney-shaped peep-holes by stud gun body side, judges pin opening direction to facilitate.
The structural design that described pin chuck adopts thin walled cylinder body and collet to combine, makes internal-expansion type axle by pin chuck clamp pin nail region, utilizes the elastic force of self to clamp pin.
Technique effect of the present utility model is: the utility model serviceability is stablized, and efficiency is high, and structure is simple, easy to operate, can weld by the pin different to length.The principle of design utilizes original stud gun body, carries out the transformation to lengthening joint, pin chuck, solve the pin that can weld different length with a kind of stud gun according to pin length specification.
