Description

Pipe tongs

Technical Field

The utility model relates to an assembly appurtenance, concretely relates to pipe tongs.

Background

When the pipe is processed, a gripper is often used, and the pipe needs to be picked up and placed at other positions. The existing gripper mostly adopts two arc-shaped tentacles to grip a round pipe in an opening and closing mode, the circular pipe gripping mode has certain limitation, the force is not easy to control, the opening and closing degree of the gripper needs to be adjusted after the pipe diameter is changed, and the adaptability is poor.

Disclosure of Invention

To the not enough among the prior art, the utility model provides a pipe tongs.

The utility model provides a pipe tongs which characterized in that: including the base lower part has set firmly vertical fixed plate the arc breach that the opening is decurrent is seted up to the lower extreme of fixed plate, is being close to the position of fixed plate side is equipped with vertical claw that colludes, the claw head that colludes the claw extends and is in the intraoral middle part of arc breach rotate on the base install with the perpendicular runner that sets up of fixed plate, the runner with the actuating mechanism linkage that sets up on the base, the tail end that colludes the claw rotates to be installed the eccentric position of runner the middle part that colludes the claw articulates there is the connecting rod, the one end of connecting rod with collude the claw and connect, the other end of connecting rod articulates on the base.

The utility model discloses a theory of operation: the arc-shaped notch is attached to the end of the pipe, the pipe wall of the pipe is located between the arc-shaped notch and the claw head at the moment, the driving mechanism drives the rotating wheel to rotate, the claw is lifted, the claw head is close to the inner wall of the arc-shaped notch and tightens the pipe wall under the action of the connecting rod, and grabbing of the pipe is completed.

Further comprises the following steps: the driving mechanism comprises an air cylinder fixedly arranged on the base, a rack is fixedly connected to a telescopic rod of the air cylinder, the rotating wheel is a gear, and the rack and the telescopic rod are arranged in parallel.

Further comprises the following steps: the base is rotatably provided with a roller, the roller is positioned on the other side of the rack relative to the rotating wheel, and the roller is in sliding fit with the rack. Under the effect of gyro wheel for rack and runner cooperation are more stable.

Further comprises the following steps: the base comprises two substrates which are arranged in parallel and provided with a certain gap, and the two substrates are fixedly connected through a connecting rod; the connecting rod, the rotating wheel and the rack are located in the gap, the fixing plate stretches across the two base plates and is fixedly connected with the two base plates, the connecting rod is located between the fixing plate and the rotating wheel, and the air cylinder is fixed outside the base plates. This makes the structure more compact.

The utility model has the advantages that: the pipe wall of the pipe is clamped under the matching action of the arc-shaped notch and the claw head, so that the purpose of grabbing the pipe is realized, the structure is simple, the operation is convenient, the pipe can adapt to various thickness specifications of pipes, even if the pipe with different specifications is subjected to mouth opening, under the matching action of the arc-shaped notch and the claw head, the arc-shaped notch is in two-point contact with the pipe, the claw head is in one-point contact with the pipe, so that the stable grabbing of the pipe is realized, and the adaptability is; the actuating mechanism who sets up passes through rack drive runner, and drive simple structure and stability, the utility model discloses overall structure is simple compact, convenient operation.
