The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is use view of the present utility model, Fig. 2 is the front view of the inner sleeve in the utility model, Fig. 3 is the top view of the inner sleeve in the utility model, Fig. 4 is the large locating wheel mechanism structure schematic diagram in the utility model, shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, numerical control pipe thread lathe inlet pipe center positioning device, this device comprises inner sleeve 1, large locating wheel mechanism 2 two parts, wherein, inner sleeve 1 is fixedly mounted in chuck 3, there is flange 4 in inner sleeve 1 outside, and on flange 4, the position of corresponding claw 5 has groove, not hinder the movement of claw.Locating wheel mechanism 2 is comprised of large wheel support 6, bull wheel 7, large wheel shaft 8 greatly, the bottom of large wheel support 6 is fixedly mounted on the position between two claws 5 in inner sleeve 1, bull wheel 7 is sleeved on large wheel shaft 8, large wheel shaft 8 ends are through locating by split pin 1 behind the hole of large wheel support 6, and the inside edge of all bull wheels 7 is positioned on same disc.The effect of inner sleeve is fixing bull wheel detent mechanism, and the effect of bull wheel detent mechanism is to allow steel pipe arrive the space forming through all bull wheels in advance between claw, and steel pipe is carried out to centralized positioning, prevents that steel pipe is due to pendulum impact claw.
Therefore in practical application, because claw is generally three, described large locating wheel mechanism 2 is three covers.
The inside edge of described bull wheel 7 and the distance between steel pipe 10 are 0.5mm, and gap is little, and accuracy is high.
Fig. 5 is the little locating wheel mechanism structure schematic diagram in the utility model, as shown in the figure, in order further to improve the positioning precision of this device, because serving as reasons three bull wheel positioning precisions in large locating wheel mechanism or not, therefore, this device also comprises little locating wheel mechanism 11, described little locating wheel mechanism 11 is by steamboat support 12, steamboat spacer sleeve 13, steamboat axle 14, steamboat 15 forms, steamboat support 12 bottoms are arranged in large wheel support 6 top installing holes, steamboat 15 is sleeved on steamboat axle 14, steamboat axle 14 ends are through locating by split pin 2 16 behind the hole of steamboat support 12, 14, steamboat axle is contained on claw 5 and outside is set with steamboat spacer sleeve 13, locating wheel mechanism 2 He little locating wheel mechanism 11 interval alternative arrangements, and all bull wheels 7 greatly and steamboat 15 inside edges are positioned on same disc.Little locating wheel mechanism has utilized two spaces between adjacent large locating wheel mechanism, has increased again detent mechanism, has so just formed bull wheel and has added steamboat and 6 take turns centering altogether, guarantees positioning precision.
Great locating wheel mechanism 2 is on the basis of three covers, and 2 He little locating wheel mechanisms 11 of described large locating wheel mechanism are respectively three covers.Described bull wheel 7 and the inside edge of steamboat 15 distance all and between steel pipe 10 is 0.5mm.
During use, first bull wheel support welding is put interior, then inner sleeve is fixed in chuck, groove on inner sleeve flange is aimed at the direction that claw enters, and after tightening, loads onto claw, large wheel shaft is passed to the hole of large wheel support and the center of bull wheel, in hole from another large wheel support, pass, by split pin one, located, the center, gap between two claws is aimed at the center of bull wheel.Afterwards, steamboat support is screwed into respectively in the upper end screw of large wheel support, steamboat axle is respectively through the center of the hole of little wheel support and steamboat spacer sleeve, steamboat, from the hole of another little wheel support, pass, by split pin two, located, steamboat and little wheel shaft are across on claw, and steamboat axle outside is set with steamboat spacer sleeve, guarantees the smooth rotation of little wheel shaft.
The utility model is directly installed on after numerical control pipe thread lathe in chuck hole, and along with chuck rotates together.During work, when steel pipe is by production line transmission, while entering after numerical control pipe thread lathe chuck, if steel pipe have bending or with numerical control pipe thread lathe decentraction, can only first touch the outer rim of bull wheel or steamboat, bull wheel or steamboat produce to roll and steel pipe guiding is entered in rear chuck hole to chuck hole in the past again pass.Because bull wheel and the gap between steamboat and steel pipe of this device are very little; only has 0.5mm; steel pipe has been subject to the restriction of center positioning device; oscillating quantity is also very little, can be contactlessly in the past chuck pass through, while therefore having solved numerical control pipe thread lathe machined steel gas thread; the problem of the claw of chuck before and after steel pipe often collides; both guarantee steel tube screw thread machining accuracy, and also protected lathe to be without prejudice, and improved the speed of processing.For different steel pipes, as long as change corresponding large and small wheel, can deal with problems, very convenient.
