Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Figure 1 to Figure 2 The reference numerals in the figure are: movable claw 1; slider 2; bump 21; outer cover 3; radial linear guide rail 4; turntable 5; eccentric arc groove 51; groove 52; bearing 6; Cylinder 8; mandrel 9; center through hole 91; push block 10.
[0019] Such as Figure 1 to Figure 2 As shown, a four-jaw centering automatic chuck for pipe processing includes a mandrel 9, at least two superimposed turntables 5 that can independently rotate around the mandrel 9 arranged on the mandrel 9, The drive mechanism that drives the turntable 5 to rotate, at least four movable claws 1 and the radial linear guide reciprocating mechanism connected with the movable claws 1 are arranged on the spindle 9, the axis of the spindle 9 is in line with the The center of circle of the turntable 5 coincides, specifically, the turntable 5 is ...

The invention relates to an automatic four-claw centering cluck for tube processing, comprising a mandril, at least two overlapped rotating discs, a driving mechanism, at least four movable claws and a radial linear guide rail reciprocator, wherein the at least two rotating discs are arranged on the mandril and can independently rotate around the mandril, the driving mechanism is arranged on the mandril and drives the rotating discs to rotate, the movable claws are connected with the radial linear guide rail reciprocator, the driving mechanism is connected with the rotating discs, at least two eccentric circular-arc slots which are mutually symmetrical are arranged on each rotating disc, and the radial linear guide reciprocator is connected with the eccentric circular-arc slots. The invention has the advantages that: the driving mechanism drives the rotating discs to rotate, the eccentric circular-arc slots rotate along with the rotating discs, the radial linear guide rail reciprocator drives the movable claws to radially move, and therefore, the centering clamping of rectangular tubes, oval tubes, double-end round flat tubes and other tubes can be realized by at least four movable claws.
Description
technical field [0001] The invention relates to a laser pipe cutting machine, in particular to a four-jaw centering automatic chuck used for pipe material processing in the laser pipe cutting machine. Background technique [0002] The chuck is a machine tool accessory that uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. The chuck is generally composed of three parts: the chuck body, the movable jaw and the jaw driving mechanism. The conventional coil-type four-jaw centering chuck manually clamps and loosens the workpiece, and the four claws are linked together, and can only be centered and clamped on round or square tubes. In recent years, there have been some pneumatic chucks (such as patent application No. 200810187615.4) or centering clamping devices (such as patent No. 200520145887. There is only a pair of V-shaped claws, and it can only clamp round tubes or square tubes centrally. The above severa...
