Description
Technical field
The utility model relates to a kind of tooling device, particularly a kind of welding valve assembled formation machine that small-sized 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, therefore 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 assembling and the compression of small-sized welding valve, also there is no special equipment, generally all adopt man-made assembly, rotation, utilize the hydraulic cylinder welding of exerting pressure, judge rule of thumb mainly whether pretightning force is enough.If the inaccurate problem of judgement occurs, the pretightning force that applies is excessive, will cause spring failure so; If pretightning force is too small, the valve mass after can not guaranteeing to weld.
The utility model content
The purpose of this utility model is to provide a kind of small-sized welding valve assembled formation machine, when having solved small-sized welding valve assembling, the pretightning force judgement is inaccurate, easily produce the 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 welding.
The technical scheme that the utility model adopts is: this small-sized welding valve assembled formation machine comprises support, be assembled in valve hold-down mechanism on support, control plate with the argon-arc welder of cooling water tank and the movement that is connected on support, and its technical essential is: described valve hold-down mechanism comprises upper platen and the pressing disc that hydraulic cylinder is controlled; Upper platen links together by the piston rod of pressure sensor and top hydraulic cylinder, the piston rod of pressing disc and bottom liquid cylinder pressure links together, the piston rod of top hydraulic cylinder drives upper platen and moves downward, the piston rod of bottom liquid cylinder pressure drives pressing disc and moves upward, to realize the compression after valve to be welded is assembled; The piston rod of fluid motor-driven top, the top hydraulic cylinder of support drives upper platen and upwards resets, and the piston rod of bottom liquid cylinder pressure drives pressing disc and resets downwards, to realize loosening after valve assembling to be welded; Bottom fluid motor-driven pressing disc drives the valve to be welded that compresses after assembling and implements welding.
Described pressure sensor is controlled the Instrument connection of the demonstration preload pressure on plate by transmission line and the movement that is connected to support.
Advantage and the good effect that the utlity model has are: because the upper platen of the utility model valve hold-down mechanism is connected by the piston rod of pressure sensor with the top hydraulic cylinder, the piston rod of pressing disc and bottom liquid cylinder pressure links together, and utilize piston rod to drive the motion of upper platen and pressing disc, realize compressing or loosening the welding valve, so its compact conformation, flexible operation, assembling are fast.During operation, valve part is placed between upper and lower platen, driving bottom liquid cylinder pressure drive pressing disc moves upward, move to manually-operated suitable position, after allowing hydraulic cylinder drive upper platen in top move downward the compression valve, valve automatic rotation after realize compressing by the bottom liquid pressure motor uses electric welding machine to implement welding, can significantly improve the valve mass after welding.Therefore, when the utility model has solved small-sized welding valve assembling, the pretightning force judgement is forbidden, and easily produces the 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 in figure: platen, 5 pressing discs, 6 bottom liquid cylinder pressures, 7 bottom liquid pressure motors, 8 hydraulic oil containers, 9 cooling water tanks, 10 argon-arc welders, 11 top hydraulic cylinders, 12 control panels on 1 top hydraulic motor, 2 pressure sensors, 3 supports, 4.
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 3, be assembled in valve hold-down mechanism on support 3, control the parts such as plate 12 with the argon arc welding machine 10 of cooling water tank 9 and the movement that is connected on support 3.Wherein the valve hold-down mechanism mainly comprises platen 4 and pressing disc 5.Upper platen 4 links together by the piston rod of pressure sensor 2 with top hydraulic cylinder 11, and pressing disc 5 links together with the piston rod of bottom liquid cylinder pressure 6.The piston rod of top hydraulic cylinder 11 drives upper platen 4 and moves downward, and the piston rod of bottom liquid cylinder pressure 6 drives pressing disc 5 and moves upward, to realize the compression after valve to be welded is assembled.The piston rod that the top hydraulic motor 1 of support 3 drives top hydraulic cylinder 11 drives upper platen 4 and upwards resets, and the piston rod of bottom liquid cylinder pressure 6 drives pressing disc 5 and resets downwards, to realize loosening after valve assembling to be welded.
Bottom liquid pressure motor 7 drives the valve to be welded that compresses after pressing disc 5 drive assemblings and is rotated, and at first realizes compressing the spot welding of valve.Argon-arc welder 10 and cooling water tank 9 lay respectively at middle part and the bottom of equipment.Then control by pedal type switch and compress the valve rotation, can easily implement welding, the speed of rotation can be set, the person that is applicable to the different operating.The all operations button all is located on the control panel 12 that is connected with support 3, and the switch that compresses the valve rotation is pedal type switch, can control the rotation that compresses valve and stop.
During valve assembling to be welded, the mold that the assembling valve is used is placed on pressing disc 5, each parts of valve are put in order and carry out assembled formation on mold, starting bottom liquid pressure motor 7 driving bottom liquid cylinder pressures 6 drive pressing discs 5 moves upward, move to manually-operated suitable position, the piston rod that starts top hydraulic cylinder 11 drives upper platen 4 and moves down, compress the valve of assembled formation by upper and lower platen 4,5, when exerting pressure, observe the instrument that shows preload pressure, reach authorized pressure and stop exerting pressure.Start argon-arc welder 10, first the valve body connecting portion of the compression valve of assembled formation carried out spot welding.Utilize foot-operated rotary switch this moment, control the rotation that compresses valve, to realize the spot welding to each position.Valve point postwelding can not sling valve, implements all welding under rotation status, can save the welding rotation platform.
After completing the valve assembly welding, the piston rod that starts top hydraulic cylinder 11 drives upper platen 4 and upwards resets, the piston rod of bottom liquid cylinder pressure 6 drives pressing disc 5 and resets downwards, loosen valve, the piston rod drive pressing disc 5 of bottom liquid cylinder pressure 6 is resetted downwards, just can lift by crane the welding valve of completing the assembly welding operation.
