Description

Welding valve assembled formation machine
Technical field
The utility model relates to a kind of tooling device, particularly a kind of welding valve assembled formation machine that large-scale welding valve is assembled and welded that is exclusively used in for the manufacture of the welding valve.
Background technology
Should apply pretightning force after the assembling of welding valve and just can weld, because the two ends of welding valve do not have flange, so can't utilize the bolt degree of tightness of two end flanges to control pretightning force.For guaranteeing welding quality, just need special hold down gag, and show applied pressure.But, at present to the assembling of welding valve with compress, also there is not special equipment, generally all adopts artificial assembling, rotation, utilize the hydraulic cylinder welding of exerting pressure, judge rule of thumb mainly whether pretightning force is enough.If take place to judge inaccurate problem, the pretightning force that applies is excessive, will cause spring failure so; If pretightning force is too small, the valve mass after then can not guaranteeing to weld.
The utility model content
The purpose of this utility model provides a kind of welding valve assembled formation machine, pretightning force is judged inaccurate when having solved the assembling of large-scale welding valve, easily produce problems such as welding quality, its compact conformation, flexible operation, assembling are fast, the setting pretightning force of exerting pressure is accurate, can significantly improve the valve mass after the welding.
The technical scheme that the utility model adopts is: this welding valve assembled formation machine comprises support, be assembled in valve hold-down mechanism on the support, have the argon-arc welder of cooling water tank and plate is controlled in the movement that is connected on the support, and its technical essential is: described valve hold-down mechanism comprises displacement disc and top disk and the lower disk of hydraulic cylinder control; The displacement disc that is assembled on the pull bar guide rail links together by pressure sensor and roof pressure piston rod, and under the driving of roof pressure hydraulic cylinder, move downward along the pull bar guide rail and compress valve, support top and roof pressure hydraulic cylinder are set up in parallel the top and draw hydraulic cylinder, displacement disc draws piston rod to be connected with the top, draw on the top under the driving of hydraulic cylinder, the top draws piston rod pulling displacement disc and top disk to move upward along the pull bar guide rail to loosen valve, the top disk is hinged by pressure bearing and displacement disc, the lower disk of fluid motor-driven fits together by pressure bearing and travelling table, travelling table is assembled on the track bracket of support, and moves back and forth along the rail length direction.
The instrument that described pressure sensor is controlled the demonstration preload pressure on the plate by transmission line and the movement that is connected support is connected.
Advantage and the good effect that the utlity model has are: because the utility model adopts the displacement disc that links together by pressure sensor and roof pressure and tension and compression piston rod, and utilize by the hinged top disk of pressure bearing and displacement disc, the lower disk that fits together by pressure bearing and travelling table, compress or loosen the welding valve, so its compact conformation, flexible operation, assembling are fast.Because it can be when travelling table protracts, valve part is placed on the lower disk of fluid motor-driven, travelling table is retreated, the descending pinch valve of piston rod, so guarantee that by pressure sensor and pressure bearing the pretightning force that applies is accurate, also can utilize fluid motor-driven bottom rotary disk to rotate, the valve after realizing compressing rotates automatically, use electric welding machine to weld, can significantly improve the valve mass after the welding.Therefore, pretightning force was judged inaccurately when the utility model had solved the assembling of large-scale welding valve, easily produced problems such as welding quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is side view.
Sequence number explanation among the figure: 1 roof pressure hydraulic cylinder, 2 roof pressure piston rods, 3 pressure sensors, 4 displacement discs, 5 top disks, 6 argon-arc welders, 7 cooling water tanks, 8 pressure bearings, 9 pull bar guide rails, 10 travelling tables, 11 lower disk, 12 guide rail brackets, 13 hydraulic motors, 14 move control panel, 15 tops draw piston rod, 16 tops to draw hydraulic cylinder.
The specific embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1~2.This welding valve assembled formation machine comprises support, be assembled in valve hold-down mechanism on the support, have the argon arc welding machine 6 of cooling water tank 7 and parts such as plate 14 are controlled in the movement that is connected on the support.Wherein the valve hold-down mechanism mainly comprises roof pressure, pushes up displacement disc 4 and top disk 5 and lower disk 11 3 parts of drawing hydraulic cylinder 1,16 controls.The displacement disc 4 that is assembled on the pull bar guide rail 9 links together by pressure sensor 3 and roof pressure piston rod 2, and moves downward along pull bar guide rail 9 under the driving of roof pressure hydraulic cylinder 1, to realize compressing after the valve assembling to be welded.Support top and roof pressure hydraulic cylinder 1 are set up in parallel the top and draw hydraulic cylinder 16, displacement disc 4 draws piston rod 15 to be connected with the top simultaneously, and draw on the top under the driving of hydraulic cylinder 16, the top draws piston rod 15 pulling displacement discs 4 and top disk 5 to move upward along pull bar guide rail 9 to loosen valve.The instrument that pressure sensor 3 is controlled the demonstration preload pressure on the plate 14 by transmission line and the movement on being connected support is connected.Top disk 5 is hinged by pressure bearing 8 and displacement disc 4.The lower disk 11 that hydraulic motor 13 drives fits together by pressure bearing 8 and travelling table 10, and hydraulic motor 13 is fixed on the travelling table 10, and travelling table 10 is assembled on the track bracket 12, and moves back and forth along the rail length direction.Hydraulic motor 13 drives the valve to be welded that compresses after the lower disk 11 drive assemblings and is rotated, and realizes compressing the spot welding of valve.Argon-arc welder 6 and cooling water tank 7 lay respectively at middle part and the bottom of equipment.Compress the valve rotation by pedal type switch control, can easily realize welding, the speed of rotation can be set, the person that is applicable to the different operating.The all operations button all is located at the movement that is connected with support and controls on the plate 14, and the switch that compresses valve rotation is pedal type switch, can control the rotation that compresses valve and stop.
When valve to be welded is assembled, travelling table 10 is stretched out forward, the mold that the assembling valve is used is placed on the lower disk 11, and each parts of valve are put in order and carry out assembled formation on the mold, and travelling table 10 is mobile resetting backward.The roof pressure piston rod 2 that starts roof pressure hydraulic cylinder 1 moves down, and compresses the valve of assembled formation by top disk 5, when exerting pressure, observes the instrument that shows preload pressure, reaches authorized pressure and stops to exert pressure.Start argon-arc welder 6, the valve body connecting portion that compresses valve to assembled formation carries out spot welding earlier, utilizes foot-operated rotary switch simultaneously, and control compresses the rotation of valve, to realize the spot welding to each position.Valve point postwelding can not sling valve, all welds under rotation status, can save the welding rotation platform.
After finishing valve assembling welding, start the top and draw the top of hydraulic cylinder 16 to draw piston rod 15 to move up, loosen valve, travelling table 10 moves forward and stretches out, and just can lift by crane the welding valve of finishing the assembling weld job.
