Description

Pipeline clamping device

Technical Field

The utility model relates to a pipeline production facility technical field especially relates to a pipeline clamping device.

Background

In the process of prefabricating and producing the pipeline, the groove machining of the pipe fitting is always an important process. The appearance of the two-axis numerical control beveling machine enables the bevels of the pipe fittings to well complete the function, and can realize the shapes of the bevels in various shapes on the pipe fittings. However, the quality and form of the groove are determined to some extent by the quality and form of the pipe clamping device due to the high reliability and high precision requirements of the machine tool. Historically, due to design reasons, after a clamped pipeline works for a long time, the pipeline deforms to a certain degree, and therefore a series of subsequent works are influenced. Accordingly, there is a need to provide a pipe gripping device that can be used for long periods of time without deforming the pipe.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a pipeline clamping device, including the nut seat, install the slide rail on the nut seat, be equipped with sliding connection's chuck one and chuck two on the slide rail, chuck one and chuck two are connected respectively in the both ends of same two-way lead screw and can realize opposite direction motion or motion dorsad, and hydraulic motor is installed to the one end of two-way lead screw, are equipped with respectively on chuck one and the chuck two and are used for the cooperation to press from both sides tight pipeline press from both sides tight face one and press from both sides tight face two.

The technical effects are as follows: the utility model discloses pipeline clamping device to among the prior art has carried out optimization adjustment, and the chuck passes through removal such as hydraulic motor, two-way lead screw to can add into the pipe fitting of different pipe diameters, avoid the defect of traditional tight structure of clamp, solve the problem that pipeline clamping device made the pipeline warp.

The utility model discloses the technical scheme who further injects is:

in the pipe clamping device, the first chuck and the second chuck adopt the embedded structure and are provided with two pairs of embedded surfaces.

In the pipe clamping device, the first chuck and the second chuck are provided with the embedded surfaces respectively in the inclined surface structures which are matched with each other.

In the pipeline clamping device, the first clamping head is provided with two first clamping surfaces which are symmetrically arranged and are respectively positioned at the outermost sides of the first clamping head; the second clamping head is provided with two second clamping surfaces which are symmetrically arranged and are respectively positioned at the outermost sides of the second clamping head.

According to the pipeline clamping device, the end covers are arranged at the two ends of the nut seat, one end of the bidirectional screw rod is fixed on the end covers, and the other end of the bidirectional screw rod is connected with the hydraulic motor through the rigid coupling and is fixed on the other end cover.

The utility model has the advantages that:

(1) the utility model can realize automatic centering of the pipeline, and can complete the process without special centering when the pipeline clamping device clamps the pipe fitting, thereby reducing the centering process in the traditional beveling machine and realizing automatic centering;

(2) the utility model provides a chuck excellent in design, when the pipe fitting clamping of different pipe diameters arrived this equipment, because the characteristic of chuck design, can both offset pressure under the different situation to guarantee that the pipe fitting can not take place to warp in the course of the work.
