When the pipe material fixing device is used, a pipe material is placed on the top surface of the chuck, the rotary table is rotated, the rotary table drives the clamping jaws to slide in the guide grooves through the connecting rods when rotating, the clamping jaws move synchronously, the pipe material can be fixed, and the pipe material is completely concentric relative to the center of the chuck.

Furthermore, for convenient operation, carousel fixedly connected with from aligning handle, stretch out from the chuck side from aligning handle.

Preferably, the guide groove is arc-shaped.

Preferably, the jaw is cylindrical.

Preferably, the clamping devices are provided with six groups.

Wherein, every group chucking device all corresponds and is provided with a plurality of groups connecting rod mounting hole, can install different mounting holes with connecting rod one end to the excircle diameter size that the adjustment jack catch is constituteed can adapt to the work piece of more different diameters.

Preferably, the bottom of the chuck is provided with a support leg.

Compared with the prior art, the utility model beneficial effect who has is:

pipe material processing automatic centering frock, structural design is reasonable ingenious, through mechanical centering, centering is accurate, avoids off-centre, easy and simple to handle moreover, labour saving and time saving avoids repeated adjustment, has stopped installation off-centre in the past and has caused add man-hour knife, disconnected sword, part scrap, extravagant raw materials scheduling problem.

Detailed Description

The invention will be further described with reference to specific examples. However, in the description of the present invention, it should be noted that the terms "front end", "rear end", "left and right", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "communicating" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The utility model discloses in view of the defect of former process mechanism, the event provides an ingenious pipe material processing automatic centering frock.

As shown in fig. 1 to 3, the automatic centering tool for processing a tube material in the embodiment includes a circular chuck 1, a turntable 2 concentrically arranged with the chuck 1 is arranged on the bottom surface of the chuck 1, and a plurality of clamping devices are arranged on the turntable 2, and the clamping devices are circumferentially distributed in an array shape with a central axis 7 of the chuck 1 as a center; wherein, carousel 2 fixedly connected with is from aligning handle 8, stretches out from chuck 1 side from aligning handle 8. The bottom of the chuck 1 is provided with a support leg 10.

The chucking device be provided with six groups, every chucking device of group all includes connecting rod 4 and columniform jack catch 6, jack catch 6 sets up the one end at connecting rod 4, jack catch 6 stretches out from 1 top surface of chuck through curved guide way 3 on the chuck 1, the other end of connecting rod 4 passes through pin joint 5 and is connected with carousel 2.
