Abstract

The utility model relates to a clamp fixture mechanism of a forming connecting tube for a fluorescent lamp bulb, comprising a first clamp head and a second clamp head which extend in the direction of a diameter, wherein, the first clamp head and the second clamp head clamp and hold the lamp bulb outside the end. Two lamp bulbs are arranged in the direction of the diameter. A first driving seat is extended upward at the inner end of the first clamp head. A second driving seat is extended downward at the inner end of the first clamp head. The first driving seat is provided with a pair of adjustable rods to make the first driving seat has a bunt distance adjacent to a fixing seat. The fixing seat is provided with one cam. The final distance of the two lamp bulbs is fixed by means of the rotation of the cam. One running wheel is extended upward of the second driving seat. The running wheel is driven by a cam combination preset by a machine. The second driving seat and the first clamp head move again and again inward and outward. The points of the melting of the two lamp bulbs can be combined tightly.

Description

Fixture of forming connecting tube for fluorescent lamp bulb

The utility model is that clamp mechanism is taken in a kind of moulding of fluorescent tube, in order to two energy-conservation tube clamping and be welded together effectively automatically.

When two energy-conservation fluorescent tubes were desired to be welded together, fluorescent tube, was heated with heating tools such as gas furnaces in inboard, the nearly lower end of fluorescent tube by parallel clamping, to fusing, blew and broke through, and is at last that two tubes are close, and fusing place is combined.Therefore, habitual adapter clamp mechanism is to be placed on the machine body with dozens of radially, around the machine center rotation, makes the fluorescent tube that is held carry out each work program in regular turn.In common adapter clamp mechanism, at circumferential direction clamping two fluorescent tubes, so, in each heating work station, that is, take over anchor clamps mechanisms grip fluorescent tube, all can stop to each workstation, need heating person, then the gas flame head is removed, made the adapter clamp mechanism move to next workstation, simultaneously, next group fluorescent tube moves in this workstation, processes operation again.After fluorescent tube was heated fusing in regular turn, blowing was blown brokenly fusing place again, again to take over clamp mechanism with two fluorescent tube closings, fusing place of two fluorescent tubes was welded together at last.Because habitual adapter clamp mechanism is in circumferential direction clamping two fluorescent tubes,, except increase bothers, more cause the instability of gas flame so when shifting workstation, the gas flame head must shift-in, shift out.In addition, when the welding fluorescent tube, it is only close with two fluorescent tubes that tradition is taken over clamp mechanism, expects that fusing place of two fluorescent tubes can combine.But the fusion of fluorescent tube is not very smooth, so, two welds near after, often produce to engage not closely, or situation such as gap in case two in conjunction with there being any space between fluorescent tube, all belong to substandard product, can't be carried out the operation that next stage vacuumizes.So, can carry out automatic production though tradition is taken over clamp mechanism, but disqualification rate being too high, poor effect waits further perfect.

The applicant is in view of the above-mentioned defective of prior art, through endeavouring research, improve repeatedly, finally develop a kind of moulding of fluorescent tube and take over clamp mechanism, this mechanism, draws back to the location at last again and locates after inside and outside moving with tension mode closing fluorescent tube weld, make the very closely fusion of fluorescent tube weld, guarantee that its tight produces.

Main purpose of the present utility model just provides a kind of moulding of fluorescent tube and takes over clamp mechanism, this mechanism comprises, extend with diametric(al), first chuck and second folder respectively at outer end clamping fluorescent tube, making two fluorescent tubes be diametric(al) arranges, first chuck the inner extends upward first retainer, extend second retainer downwards, first retainer can be pulled inward and near taking over permanent seat default on the chuck body, and first retainer establishes a pair of adjustable rod, makes first retainer near behind the permanent seat predetermined distance be arranged, tool one cam on the permanent seat, borrow the cam rotation, with the extrapolated segment distance of first retainer, to fix the final distance of two fluorescent tubes, and the downward extended rolling wheel of second retainer, the cam set of being preset by machine drives, and makes second retainer together with in first chuck work, move repeatedly outward, promptly, after the two fluorescent tube closings, in borrowing, move repeatedly outward, fusing place is combined closely, so combination fully closely can be provided.

fluorescent tube

40,50 is moved in circumferential direction, accept the heating of heating endless tube 60, gas flame head 70 in regular turn.As shown in Figure 5, the end inboard at first is heated endless tube 60 heating under two

fluorescent tubes

40,50, to carry out preheating.Then, as shown in Figure 6, two

fluorescent tubes

40,50 move to gas flame head 70 places, and the heating of fixing a point makes the

melting end

41,51 of inboard,

fluorescent tube

40,50 lower end begin fusing.Again

fluorescent tube

40,50 being moved to next gas flame head 70(such as Fig. 7) reheat blows simultaneously, makes melting

end

41,51 outstanding.As shown in Figure 8, because this moment, melting

end

41,51 quite melted, promptly be that melting

end

41,51 is blown brokenly so blow.As Fig. 9 institute not, two

fluorescent tubes

40,50 are furthered then, be actually first fluorescent tube 40 is moved and close second fluorescent tube 50.Note that the close degree of two

fluorescent tubes

40,50 this moment, nearer than its predetermined distance, so two melting ends 41,51 by closely and closing excessively together, simultaneously, make first fluorescent tube 40 move, make weld portion 80 form a closely knit combination with a small amount of shift-in and the mode repetitiousness of shifting out.At last, as shown in figure 10, first fluorescent tube 40 is outwards drawn back, make two

fluorescent tubes

40,50 be combined into the one of connection thereby make two

fluorescent tubes

40,50 reach predetermined distance.And in the above-mentioned operation, only mobile anchor clamps and fluorescent tube need not the traveling heater tool, so easy and simple to handle, gas flame is stable.

For two

fluorescent tubes

40,50 are fused in the above described manner, the utility model provides one to take over clamp mechanism 100, as shown in Figure 1, it comprises a chuck body 10, a permanent seat 11 is established in chuck body 10 back segments top, have a rotating cam 12 on the permanent seat 11, and cam 12 tops establish a running roller 13 so that machine driving cam 12.Chuck body 10 leading portion downsides are provided with first chuck 20 and one second chuck 30, each tool one clamping part 21 of these two chuck front ends, 31, with clamping

fluorescent tube

40 or 50, this two clamping

part

21,31 for being provided with in tandem, in other words, after adapter clamp mechanism 100 is mounted to machine, two

clamping parts

21,31 are positioned at the tube diameter direction, and when taking over clamp mechanism 100 rotations, make two

clamping parts

21,31 rotate along the tube circumference direction, so according to as Fig. 5 to mode shown in Figure 10, clamping two

fluorescent tubes

40,50 rotate to each workstation in regular turn in circumferential direction, and heating appliances is located at two fluorescent tubes 40, need not between 50 into, go out mobile.End has extended upward one first retainer, 22, the first retainers, 22 upper ends and flatly has been provided with a pair of adjustable rod 23 after first chuck 20, and this adjustable rod 23 is provided with abreast and extends to permanent seat 11.By making two adjustable rods 23 stretch out first retainer, 22 certain distances backward, so, when first retainer 22 by to rear drive the time, adjustable rod 23 can prop up permanent seat 11, make the permanent seat 11 and first retainer 22 keep a predetermined distance, at this moment, promptly state shown in Fig. 3 and 9 makes first fluorescent tube 40 rely on second fluorescent tube 50.On first retainer 22, establish a running roller 24 in addition, when first retainer 22 relied on permanent seat 11, running roller 24 just propped up cam 12, as shown in Figure 3, but when running roller 13 is driven, when making cam 12 rotations, cam 12 is with drive roller wheel 24, so that first retainer 22 outwards shifts out, as shown in Figure 4, that is, first chuck 20 is outwards shifted out first fluorescent tube 40, thereby make first fluorescent tube 40 and second fluorescent tube 50 reach as shown in figure 10 final distance.

See also Fig. 2, first chuck 20 further comprises one second retainer 25, has a running roller 26 on second retainer 25, by the (not shown) that cam set drives of machine body, make second retainer 25 can do to advance together with first chuck 20, what go out moves repeatedly, in other words, make first retainer 22 near permanent seat 11(such as Fig. 3 when first chuck 20 is moved) time, that is, first fluorescent tube, 40 closings, second fluorescent tube 50(such as Fig. 9) time, make first chuck 20 do by second retainer 25, what go out moves repeatedly, that is, after weld portion 80 closings of first fluorescent tube 40 and second fluorescent tube 50, first fluorescent tube 40 is done, go out mobile, make two

fluorescent tubes

40,50 weld portion 80 closely fuses, and just by the cam 12 of permanent seat 11 first retainer 22 is released at last, makes two

fluorescent tubes

40,50 reach final distance.

For instance, suppose that the distance after the predetermined fusion of two fluorescent tubes is 3mm, it is that directly closing is the distance of 3mm with after the fusing of two fluorescent tubes that tradition is taken over anchor clamps, carries out the weld portion fusion, so, often too high because of the not good condemnation factor that causes of fusion.The utility model mechanism then is after the fusing of two fluorescent tubes, and first closing is the distance for weak point, for example 1.5mm than 3mm, through into and out of moving repeatedly, make the closely knit fusion of weld portion, again two fluorescent tubes are removed to the distance of 3mm, so can form closely knit interfused weld portion, obtain absolute good finished product.

In sum, the structure of the utility model mechanism and arrangement kenel are prior art does not see, and really can overcome the defective of conventional brace, and reaches desired result.
