Abstract
Disclosed is a girth welding seam internal pneumatic protection device which is used for an internal part of a circular component to be welded so as to pneumatically protect the backside of a welding seam. The girth welding seam internal pneumatic protection device is characterized in that the device is composed of a main clamp, a support and shrinking device, a push-pull sleeve and a locking piece. The support and shrinking device is fixed inside the main clamp, and the push-pull sleeve and the locking piece are mounted on the support and shrinking device. The main clamp is composed of two fixed protection blocks and two trapezoidal mobile protection blocks. The two trapezoidal mobile protection blocks are arranged upwards and downwards, the two fixed protection blocks form the main clamp from the left and right, and the two trapezoidal mobile protection blocks are connected with the support and shrinking device. The central part of the two fixed protection blocks and the two trapezoidal mobile protection blocks is provided with a gas storage groove, and protection air holes are arranged outside the gas storage groove. The outside of the central part of the two fixed protection blocks and two trapezoidal mobile protection blocks is provided with a groove, and an air inlet is arranged on the two fixed protection blocks. The device has the advantage of protecting the backside welding seam of a circular component.
Description
Technical field: the invention is to be used for ring-like part to be welded inside, sealing run is played the welding protection device of gas shield.
Background technology: at present; when ring-like part to be welded is welded; positive weld seam is easily taked safeguard measure; but ring-like back of weld protection ratio is difficulty; basically not protection, the weld seam at the back side is exposed in the air, and weld seam is easily by pollutions such as oxygen, hydrogen or nitrogen; produce weld defect, influence welding quality.
Summary of the invention: the purpose of the invention provides a kind of when ring-like part to be welded is welded, the circumferential weld internal gas protection device that can carry out gas shield to sealing run; The purpose of the invention is to realize by following technical scheme: circumferential weld internal gas protection device, it is characterized in that forming by main folder tool, support and constriction device, push-and-pull sleeve and locking member, support with constriction device and be installed on the main folder tool inside, the push-and-pull sleeve is installed on support and the constriction device, and locking member is installed on support and the constriction device; The main folder tool is made of two fixing protection pieces and two trapezoidal mobile protection pieces; two trapezoidal mobile protection pieces are put up and down, two fixing protection pieces constitute the main folder tool about dividing; two trapezoidal mobile protection pieces are connected with constriction device with support; be shaped on air reservoir, be shaped on the protection pore at two fixing protection pieces and two trapezoidal mobile protection piece middle parts in the air reservoir outside; be shaped on groove at two fixing protection pieces and outside, two trapezoidal mobile protection piece middle parts, on two fixing protection pieces, be shaped on air inlet.
The advantage of the invention: owing to be shaped on air reservoir, be shaped on the protection pore in the air reservoir outside at two fixing protection pieces and two trapezoidal mobile protection piece middle parts, be shaped on groove at two fixing protection pieces and outside, two trapezoidal mobile protection piece middle parts, on two fixing protection pieces, be shaped on air inlet, when the ring-like part to be welded of welding, the weld seam at the back side has gas shield, be difficult for producing weld defect, improved the weld seam welding quality; Main folder tool profile can be according to ring-like part interior shape design to be welded, and adaptability is good, and is simple in structure, and cost is low.
Description of drawings:
Fig. 1 is the circumferential weld internal gas protection device structural representation that ring-like part to be welded is housed;
Fig. 2 is the structure schematic diagram of signing an undertaking of the main folder in the circumferential weld internal gas protection device;
Fig. 3 is the circumferential weld internal gas protection device schematic diagram.
Among the figure: 1, fixing protection piece 2, trapezoidal mobile protection piece 3, support and constriction device 4, push-and-pull sleeve 5, locking member 6, air inlet 7, ring-like part 8 to be welded, weld seam 9, protection pore 10, air reservoir 11, groove
The specific embodiment: circumferential weld internal gas protection device, it is characterized in that forming by main folder tool, support and constriction device, push-and-pull sleeve and locking member, support with constriction device and be installed on the main folder tool inside, the push-and-pull sleeve is installed on support and the constriction device, and locking member is installed on support and the constriction device; The main folder tool is made of two fixing protection pieces and two trapezoidal mobile protection pieces; two trapezoidal mobile protection pieces are put up and down, two fixing protection pieces constitute the main folder tool about dividing; two trapezoidal mobile protection pieces are connected with constriction device with support; be shaped on air reservoir, be shaped on the protection pore at two fixing protection pieces and two trapezoidal mobile protection piece middle parts in the air reservoir outside; be shaped on groove at two fixing protection pieces and outside, two trapezoidal mobile protection piece middle parts, on two fixing protection pieces, be shaped on air inlet.
Main folder tool profile can be according to ring-like part interior shape design to be welded.
Support is the three-legged structure of using always with constriction device, changes the height that length on one side promptly changes support, and its effect is to play to support ring-like part to be welded.
During use, circumferential weld internal gas protection device is contained in ring-like part to be welded inside, enters air reservoir, enter in the groove by the protection pore again, protected sealing run by air admission hole input protection gas.
