Description of the drawings
Fig. 1 is the overall schematic after tool of the present invention is installed;
Fig. 2 is the overall structure diagram of tool of the present invention;
Fig. 3 is that briquetting compresses convoluted diaphragm structural representation.
Specific embodiment
With reference to the accompanying drawings and examples the present invention is further illustrated.
As shown in Figure 1-2, Flange changer pressure sensing component laser welding jig of the invention, the tool is arranged on weldering Connect on workbench 20, for fixing Flange changer to be welded 13, then convoluted diaphragm 12 be pressed on Flange changer 13, The precise positioning of the position of laser head 21 is realized by adjusting X, Y, Z axis.Motoring platform 15 drives the rotation of Flange changer 13 one Circle, welding can be completed.Subsequently control X, Y, Z axis removes jig component, takes out the Flange changer 13 after welding, completes whole Process engineering.
Such as Fig. 2, the Flange changer pressure sensing component laser welding jig of the present invention, including mounting base 1 and installation Motoring platform 15 on mounting base 1, motoring platform 15 is driven with motor, the lower end of Flange changer to be processed 13 The upper end of motoring platform 15 is placed on, can be with the synchronous rotary of motoring platform 15.
The side of mounting base 1 is installed with sliding panel 2, and the medial surface of sliding panel 2 is vertically provided with skate machine Structure, slide mechanism includes the Pneumatic slid platform 4, cylinder and guide rod with the diameter parallel of motoring platform 15, and Pneumatic slid platform 4 is fixed on cunning On dynamic plate 2, cylinder is arranged on Pneumatic slid platform 4, and cylinder is connected by guide rod with the sliding end of bearing installing plate 5, and cylinder passes through Guide rod band dynamic bearing installing plate 5 is slided up and down along sliding panel 2, and the other end of bearing installing plate 5 is compression end, compression end be provided with The coaxial bearing mounting hole of motoring platform 15, is connected by double row angular contact bearing 16 in bearing mounting hole with hold-down mechanism Connect.
Hold-down mechanism connection includes the rotating shaft 8 coaxial with motoring platform 15 and the briquetting for convoluted diaphragm 12 to be compressed 11, rotating shaft 8 is arranged in bearing mounting hole by double row angular contact bearing 16, and rotating shaft 8 can be rotated in bearing mounting hole, double Row angular contact bearing 16 can also bear axial load when ensureing that rotating shaft 8 is rotated, and the upper end of bearing mounting hole is provided with bearing lock Tight nut 6, lower end is provided with bearing cap 7, and double row angular contact bearing 16 is sealingly mounted at axle by bearing lock nut 6 and bearing cap 7 Hold in installing hole.The other end of rotating shaft 8 is connected with briquetting 11 by polyurethane transfer block 9, is fixed by nut 17, and polyurethane turns Connecing block 9 has certain flexibility, can absorb the axial deviation of rotating shaft 8 and generation in the installation process of briquetting 11, incites somebody to action briquetting 11 The uniform stressed in supported flange transmitter 13 of convoluted diaphragm 12, compresses everywhere, it is ensured that Flange changer 13 and convoluted diaphragm 12 Be brought into close contact, meet welding requirements;With reference to shown in Fig. 3, the lower surface of briquetting 11 is fitted with the upper surface of convoluted diaphragm 12, by ripple Diaphragm 12 is pressed on the upper surface of Flange changer 13, when briquetting 11 compresses convoluted diaphragm 12, it is ensured that convoluted diaphragm 12 is closely pasted Close on the upper surface of Flange changer 13, and ensure that circumferentially circle exposes 1.5 to convoluted diaphragm 12 relative to the periphery of briquetting 11 ~2mm is used as welding position.Plus man-hour, by scroll chuck 14 middle part of Flange changer 13 is clamped and fixed, laser head After 21 are adjusted in place, alignment welding position carries out welding processing, and Flange changer 13 rotates a circle, and welding is completed.
Reinforcement gusset 3 is equipped with sliding panel 3 and bearing installing plate 5 so that jig structure intensity is more preferable, during welding more Plus it is steady.
Such as Fig. 3, to avoid process in the top of briquetting 11 laser is blocked, briquetting 11 is designed to top for cylinder Shape, bottom is taper, and lower diameter is more than upper diameter so that the bottom of briquetting 11 has the inclined gradient 19.;While briquetting 11 Middle part is provided with the through hole 18 coaxial with motoring platform, infringement when preventing briquetting 11 from compressing to convoluted diaphragm 12, causes flange Transmitter pressure measurement precision is reduced.Briquetting 11 is made from the copper product little to laser absorption rate, can prevent welding process because by mistake Operation (such as non-feeding makes Flange changer 13 produce welding with briquetting 11) causes to damage to tool;Simultaneously copper has good Thermal conductivity, can help weld seam position quick heat radiating, and fuel factor is reduced to greatest extent, it is ensured that convoluted diaphragm 12 is not around weld seam Can be deformed because being heated, cause end properties to decline.
Whole welding procedure is as follows:
Flange changer 13 is arranged on motoring platform 15, positioning clamping is carried out by scroll chuck 14, then by ripple Line diaphragm 12 is positioned in the little groove of the upper end of Flange changer 13, starts Pneumatic slid platform 4, and Pneumatic slid platform 4 is installed by bearing Plate 5 drives briquetting 11, and briquetting 11 compresses convoluted diaphragm 12, and (during compression, circumferentially circle is cylindrical relative to briquetting 11 for convoluted diaphragm 12 1.5~2mm is showed out, this is welding position), make together with convoluted diaphragm 12 is brought into close contact with Flange changer 13.Start Motoring platform 15, drives scroll chuck 14, flange 13 and convoluted diaphragm 12 together to rotate, and drives rotating shaft 8 to rotate, By adjusting X, Y, Z axis, make laser head 21 to welding position, Flange changer 13 and convoluted diaphragm 12 are welded, it is electronic Panoramic table 15 rotates a circle (be slightly larger than one week) to weld and completes.Control afterwards to be moved on Pneumatic slid platform 4, take out product.
