Preferably, four backing plates, wherein two relative backing plates that set up are higher than two other relative backing plates that set up, can make the jack catch on two relative cushion blocks wherein set up be higher than the jack catch on two other relative gaskets that set up for the jack catch staggers each other when centre gripping tubular product, can the thinner tubular product of centre gripping.

Preferably, the heights of the four base plates which are arranged oppositely are the same, so that the claws on the base plates which are arranged oppositely are at the same height, and the pipe can be better clamped.

Preferably, the axes of the gearwheel, the first clamping part and the second clamping part are arranged on the same straight line, and the concentric arrangement can better reduce the self-generated shake of the chuck in the rotating process.

Preferably, the large gear and the bottom plate are respectively provided with a plurality of damping holes, so that vibration in the working process can be better absorbed.

Preferably, the outer surfaces of the first clamping part and the second clamping part are respectively provided with a shell, so that the phenomenon that cuttings and dust enter the chuck in the cutting process to influence the precision of the chuck can be reduced.

Has the advantages that: the utility model discloses a set up two clamping parts, when needs cut some more slender tubular products, put into the chuck with tubular product, carry out the centre gripping to the tubular product simultaneously through two clamping parts, can increase the area of contact of chuck clamping part and tubular product, two clamping parts centre gripping simultaneously can improve tubular product and treat the rigidity in cutting the region, when the chuck drives the tubular product rotation, the tubular product treat that the cutting region can not produce the shake, thereby the life of machining precision and board has been guaranteed, also can not produce the potential safety hazard because of the tubular product shake simultaneously.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, fig. 2, fig. 3 and fig. 4, which illustrate a double-headed chuck of a laser pipe cutting machine, comprising a large gear 1, a first clamping portion 2 and a second clamping portion 3, wherein the first clamping portion 1 and the second clamping portion 3 are respectively disposed at two sides of the large gear 1, the first clamping portion 1 comprises a bottom plate 4, four backing plates 5 and four jaws 6, the bottom plate 4 is connected with the large gear 1 through bolts, through holes are respectively formed in the middle of the large gear 1 and the bottom plate 4, four sliding grooves 41 are respectively disposed on the outer surface of the bottom plate 4, the four sliding grooves 41 are circumferentially distributed in an array, the four backing plates 5 are respectively connected with the four sliding grooves 41 in a sliding manner, the jaws 6 are respectively connected to the upper surface of the four backing plates 5 through bolts, the heads of the four jaws 6 are oppositely disposed, and the second clamping portion.
