Abstract
The invention discloses an automatic welding fixture for a longitudinal joint of a spherical shell in a safety injection tank. The automatic welding fixture comprises a cylinder for containing the spherical shell in the safety injection tank. Two through holes are formed in the cylinder wall of the cylinder. The connecting line of circle centers of the two through holes intersects with and is perpendicular to the central axis of the cylinder, a welding hole allowing a welding head of a welding machine to stretch into the cylinder is formed in the cylinder wall of the cylinder, the plane formed by the center of the welding hole and the circle centers of the two through holes is perpendicular to the central axis of the cylinder, rotary shafts are arranged in the two through holes respectively, and discs connected with the spherical shell in the safety injection tank are arranged on the rotary shafts respectively. The automatic welding fixture has the advantages that the spherical shell can rotate, the automatic welding requirements can be met, and welding firmness and working efficiency can be improved.
Description
Technical field
The present invention relates to spherical shell longitudinal seam automatic welding in a kind of peace note case and connect frock.
Background technology
Peace note case is a kind of common equipment in boiler industry, because its volume is comparatively large, diameter generally more than 3 meters, when welding spherical shell, the mode of usual employing human weld, workman, when welding, needs to stand on very high platform to weld spherical shell, more dangerous, and operationally, require very high to the weld horizontal of workman, once weld bad, be a kind of very large loss concerning enterprise.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of peace of applicable automatic welding to note spherical shell longitudinal seam automatic welding in case and connect frock.
For solving the problems of the technologies described above, the technical solution used in the present invention is: in a kind of peace note case, spherical shell longitudinal seam automatic welding connects frock, comprise the cylinder holding spherical shell in peace note case, the barrel of cylinder offers two through holes, the line in the center of circle of two through hole is crossing with the axis of cylinder and vertical, soldering tip cylinder barrel is also provided with for welding machine stretches into the welding hole in cylinder, welding hole covers the longitudinal joint of spherical shell in peace note case, the center of welding hole, the plane of the center of circle three composition of two through hole is vertical with the axis of cylinder, turning cylinder is respectively arranged with in two through hole, turning cylinder is respectively arranged with and notes the disk that in case, spherical shell is connected with pacifying.
Described cylinder barrel arranged outside has the bracing or strutting arrangement of a pair support cylinder, and bracing or strutting arrangement comprises support, support is arranged the roller offseted with cylinder outer wall for a pair.
A roller in one of them bracing or strutting arrangement described is provided with driven gear, and the side of driven gear is provided with motor, and the output shaft of motor is provided with driving gear, and driving gear engages with driven gear.
Described cylinder two ends inwall is respectively arranged with the baffle plate being arranged into a circle, and baffle plate has been threaded screw, and one end of screw is noted spherical shell outer wall in case with peace and offseted.
The invention has the beneficial effects as follows: spherical shell can be rotated, so just can meet the requirement of automatic welding, firm welding can be improved and increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the front view that in peace note case of the present invention, spherical shell longitudinal seam automatic welding connects frock;
Fig. 2 is the top view of spherical shell in peace note case in Fig. 1;
Fig. 3 is the partial right side view of Fig. 1.
In figure: 1, spherical shell in peace note case, 2, cylinder, 3, welding hole, 4, turning cylinder, 5, disk, 6, support, 7, roller, 8, driven gear, 9, motor, 10, driving gear, 11, baffle plate, 12, screw, 13, connect disc.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As Fig. 1, shown in Fig. 3, in peace note case of the present invention, spherical shell longitudinal seam automatic welding connects frock, comprise the cylinder 2 holding spherical shell 1 in peace note case, the barrel of cylinder 2 offers two through holes, the line in the center of circle of two through hole is crossing with the axis of cylinder 2 and vertical, soldering tip cylinder 2 barrel is also provided with for welding machine stretches into the welding hole 3 in cylinder 2, welding hole 3 covers the longitudinal joint of spherical shell in peace note case, the center of welding hole 3, the plane of the center of circle three composition of two through hole is vertical with the axis of cylinder 2, turning cylinder 4 is respectively arranged with in two through hole, turning cylinder 4 is respectively arranged with and pacifies the disk 5 noted spherical shell 1 in case and be connected.
Conveniently in peace note case, spherical shell 1 can rotate automatically along its longitudinal joint direction, and described cylinder 2 barrel arranged outside has the bracing or strutting arrangement of a pair support cylinder 2, and bracing or strutting arrangement comprises support 6, support 6 is arranged the roller 7 offseted with cylinder 2 outer wall for a pair.
A roller 7 in one of them bracing or strutting arrangement described is provided with driven gear 8, and the side of driven gear 8 is provided with motor 9, the output shaft of motor 9 is provided with driving gear 10, and driving gear 10 engages with driven gear 8.
In order to prevent peace note case spherical shell 1 play and affect welding precision when rotation, described cylinder 2 two ends inwall is respectively arranged with the baffle plate 11 being arranged into a circle, baffle plate 11 has been threaded screw 12, and one end of screw 12 is noted spherical shell 1 outer wall in case with peace and offseted.
Operation principle of the present invention is, as shown in Figure 2, in peace note case, spherical shell 1 is assembled by multi-disc melon lobe, and two ends are fixed together by connecting disc 13, and it is interim for connecting disc 13, waits after spherical shell 1 completes welding in peace note case and can remove.Namely in peace note case spherical shell 1 first assembled by so much melon lobe after connect discs 13 by two and temporarily fix, then put it into welding after in the present invention, groundwork amount is exactly the welding between adjacent melon lobe.Owing to being by workman human weld before, and equipment is large, substantially increase work difficulty, danger coefficient, and efficiency is not high, after adopting the present invention, after in temporarily assembled peace note case, spherical shell 1 puts into the present invention, just automatic welding can be realized, greatly increase work efficiency and welding precision, be specially and disk 12 is noted spherical shell 1 two ends in case and welded rear turning cylinder 4 respectively just and pacify and note spherical shell 1 in case and be fixed together with being connected disc 13 or pacifying, then the soldering tip of automatic welder(welding machine) is stretched in cylinder 2 from welding hole 3 and spherical shell 1 peace note case is welded, starter motor 9 simultaneously, motor 9 drives roller 7 by driving gear 10 and driven gear 8, roller 7 drives cylinder 2 to rotate, because soldering tip is motionless, in peace note case, spherical shell 1 rotates, so just can realize the welding of longitudinal joint, when needs weld next longitudinal joint, only need to unclamp screw 12, then after rotating turning cylinder 4 certain angle, tightening screw 12 again, screw 12 is made to be against in peace note case on spherical shell 1 outer wall, and spherical shell 1 in peace note case is fixed, just can again weld.
