Extremely shown in Figure 5 like Fig. 1; The narrow gap of a kind of valve body heated filament welder comprises a positioner 1, a manipulator 2 and a coaster 3, and said positioner 1 mainly is made up of support 101, flip beam 102, rotary disk 103 and clamping tooling 106; On the support 101 slide rail is arranged; Flip beam 102 is rotatably connected between two supports 101, and flip beam 102 can move up and down along the slide rail on the support 101, and rotary disk 103 rotations are installed on the flip beam 102; Clamping tooling 106 is located on the rotary disk 103; Coaster 3 is slidingly mounted on and is arranged on positioner 1 one sides on the sliding rail 4, and sliding rail 4 extends in the middle of two support 101 bottoms, and manipulator 2 corresponding coasters 3 are arranged on positioner 1 opposite side.The revolution of the upset of flip beam 102 and rotary disk 103 all adopts bi-motor to realize two the driving, guarantees that motion steadily.
Like Fig. 2 and shown in Figure 4; Said clamping tooling 106 comprises the tight frock of end clamping tool 105, roof pressure 104, front and back manual dog and left and right sides hydraulic claw; On the rotary disk 103 linear slide rail is arranged; End clamping tool 105 is oppositely arranged on the linear slide rail with the tight frock 104 of roof pressure, on the tight frock 104 of roof pressure adjustable tapered pressure head is set detachably, is convenient to workpiece 5 centerings.
As shown in Figure 5, said coaster 3 comprises car body 301, and car body 301 is provided with turntable 302, and cylinder alignment pin 303 and adjustable supplemental support 304 are set on the turntable 302.Coaster 3 adopts direct current generators to drive, and the rack-and-pinion transmission is furnished with DC speed regulator and helical teeth worm type of reduction gearing, and in direct current generator built-in rotary encoder.Control device starts acceleration or braking deceleration control to DC speed regulator, and feedback pulse signal cumulative number and benchmark numerical value (default value) are carried out difference operation, realizes the essence of coaster speed and position
Really control.
As shown in Figure 3; Said manipulator 2 comprises base 201; Rotary setting column 202 on the base 201 is installed flexible crossbeam 203 through linear guides on the column 202, can realize that extensible canopy 203 moves up and down along column 202; There is welding head 204 flexible crossbeam 203 ends, and extensible canopy 203 can drive welding head 204 and move forward and backward.The flexible employing rack-and-pinion transmission of flexible crossbeam 203 goes up and down to adopt the screw mandrel transmission.Welding head 204 adopts the argon tungsten-arc welding heated filament, and utilization rotating the arc technology makes the abundant penetration in workpiece grooves both sides, and adopts synchronous control technique paired pulses welding electric heating and heater current to control, and effectively controls arc blow and produces.Welding head 204 also have the tungsten electrode end about, horizontal arc voltage measuring ability, realize that weld seam follows the tracks of neutralization.
This welder is welded by electric control system controls realization mechanization automatically, and this control system is by the positioner control device, and manipulator control device and welding head control device are formed.The positioner control device is controlled positioner 1 and coaster 3 simultaneously, and can control with the interlock of manipulator control device, reserves the control interface.
Positioner 1 can be realized synchronization lifting, upset, revolution and the piece-holder function of flip beam 102, rotary disk 103 and clamping tooling 106 under the control of positioner control device.Wherein, go up and down, overturn and turn round and to realize accurate position control, satisfy work-handling, the memory of welding starting point and number of turns tally function.And the flip-flop movement of flip beam 102 employing close-loop control mode, thereby realize accurate angle position control to flip beam 102 flip angles.
Manipulator 2 can realize that flexible crossbeam 203 goes up and down, welding head is 204 flexible, column 202 motorings and pneuma-lock function under the control of manipulator control device.
The course of work of the present invention is following:
Flip beam 102 rise to peak, 102 times zero-bits of flip beam (axis of rotation perpendicular to horizontal plane,
Rotary disk 103 is downward), simultaneously 103 times zero-bits of rotary disk (on the rotary disk 103 linear slide rail perpendicular to flip beam 102, and the end clamping tool 105 of valve body is positioned at coaster 3 zero-bits one side).
2. coaster 3 is in zero-bit, and lifting workpiece 5 is to coaster 3, and with cylinder alignment pin 303 location, workpiece 5 locating surfaces are that valve body is taken over endoporus, and adjustable supplemental support 304 supporting workpieces 5 both sides keep workpiece 5 at horizontal level.
3. coaster 3 runs to its cylinder alignment pin 303 axial lines by motor-driven and overlaps the position with positioner 1 median plane (XY face), and coaster 3 walking positions can accurately be controlled.
4. flip beam 102 drops to the position that clamping tool 105 center lines in the end equate with valve body center line height, and lifting position is accurately controlled through electrical system.
5. clamping tooling operation: clamping tool 105 lifting platforms of the hand end hold out against table top and valve body bottom surface; Manual dog, left and right sides hydraulic claw clamp before and after clamping then; The tight frock 104 of hand roof pressure; And the center line and the valve body central lines of regulating tapered pressure head, compress the valve body apical pore fully until tapered pressure head.
6. flip beam 102 rises to peak, and flip beam 102 overturns 90 ° to the welding position (being that the valve body center line is perpendicular to horizontal plane), and coaster 3 returns zero-bits simultaneously, and clamping workpiece finishes.
7. regulate manipulator 2 positions, the narrow gap of welding head 204 centering valve body butt tubes groove welds.
8. after welding was accomplished, flip beam 102 rose to peak, 102 times zero-bits of flip beam, 103 times zero-bits of rotary disk simultaneously.
9. coaster 3 runs to the position that its cylinder alignment pin 303 axial lines overlap with positioner 1 median plane (XY face), coaster 3 zero loads.
10. flip beam 102 descends, and the just in time slotting valve body adapter of the cylinder alignment pin 303 on the coaster 3 endoporus is gone into, and the valve body both sides just in time are supported on the adjustable supplemental support 304.
11. the clamping tooling operation: left and right sides hydraulic claw unclamps; The front and back manual dog is unclamped; Clamping tool 105 lifting platforms of the hand then end make claw leave the valve body bottom surface fully; The tight frock 104 of hand roof pressure makes tapered pressure head leave valve body apical pore (tapered pressure head is installed in cross and regulates on the planker, but centering) fully.
12. positioner 1 goes up and down to peak, 3 times zero-bits of coaster are waited for hanging workpiece 5.
This programme installation way can guarantee that valve body butt tube axis overlaps with positioner 1 axis of rotation, needn't carry out centering, directly welds.The registration error that allows valve body butt tube axis and valve axis simultaneously is less than 10mm.
Embodiment two:
As shown in Figure 6, this device has two positioners 1, two manipulators 2 and 3, two positioners 1 of a coaster to be oppositely arranged, and the centre is provided with 3, two positioners of coaster, 1 outside correspondence manipulator 2 separately.
Adopt two positioners of this configuration mode, 1 a shared coaster 3, not only practiced thrift a coaster 3, and equipment arranges compactlyer, it is little to take up room, and can further improve utilization rate of equipment and installations, enhances productivity.
