the positioning structure comprises a supporting pipe fixedly installed at one end, far away from the supporting plate, of the positioning pipe, at least two pressing blocks which move on the supporting pipe in the radial direction and are in contact with the inner wall of the circular pipe, a sliding block which is installed in the supporting pipe in a sliding mode and is used for being in contact with the pressing blocks to push the pressing blocks to move, and a driving module which is fixedly installed at the bottom of the mounting seat and is used for driving the sliding block to move.

Preferably, the slider is round table-shaped, and the diameter of the slider near one end of the supporting tube is smaller than the diameter of the slider near one end of the driving module.

Preferably, the driving module is an air cylinder, a hydraulic cylinder or an electric push rod.

Preferably, one end of the sliding block, which is far away from the pressing block, sequentially penetrates through the positioning tube, the supporting disc and the mounting seat, and is fixedly connected with the movable rod of the driving module through a connecting rod.

Preferably, a cover used for limiting the movement of the sliding block is arranged at one end of the supporting tube far away from the positioning tube.

This pipe location straining device adopts drive module to drive the slider and makes linear motion to extrude the briquetting, make the briquetting carry out the tensioning to the pipe from the inside of pipe, adopt the mode of inside tensioning fixed position, can avoid location structure occupation welding space effectively, be applicable to multiple and weld and use convenient to use in the dress environment.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and fig. 2, the utility model provides a positioning and tensioning mechanism for a welding round tube, which comprises a mounting seat 1, a supporting disk 2 fixedly mounted on the top of the mounting seat 1 for supporting the end of the round tube, a positioning tube 3 located at one end of the supporting disk 2 far away from the mounting seat 1 for positioning the end of the round tube, and a positioning structure mounted on the positioning tube 3 for tensioning and fixing the round tube;

the positioning structure comprises a supporting tube 4 fixedly installed at one end, far away from the supporting plate 2, of the positioning tube 3, at least two pressing blocks 5 which move on the supporting tube 4 in the radial direction and are in contact with the inner wall of a circular tube, a sliding block 6 which is installed in the supporting tube 4 in a sliding mode and is used for being in contact with the pressing blocks 5 to push the pressing blocks 5 to move, and a driving module 7 which is fixedly installed at the bottom of the installation seat 1 and is used for driving the sliding block 6 to move.

It should be noted that the driving module 7 is used for driving the sliding block 6 to move linearly, and the driving module 7 is an air cylinder, a hydraulic cylinder or an electric push rod.

One end, far away from the pressing block 5, of the sliding block 6 sequentially penetrates through the positioning tube 3, the supporting disc 2 and the mounting seat 1, and is fixedly connected with a movable rod of the driving module 7 through a connecting rod 8.

When using, overlap an end of pipe to registration arm 3 for the port position and the supporting disk 2 contact of this end, thereby accomplish the preliminary location work of pipe, rethread drive module 7 promotes slider 6 and removes, makes 6 extrusion briquetting 5 of slider, thereby makes briquetting 5 and the contact of pipe inner wall, thereby fixes the pipe on stay tube 4, accomplishes the location work of pipe.

This pipe location straining device adopts the mode of inside tensioning fixed position, can avoid location structure to occupy the welding space effectively, is applicable to and uses convenient to use in the multiple welding environment.

Specifically, in order to enable the pressing block 5 to move along with the sliding block 6 and extend out of the inner diameter of the supporting tube 4 in the radial direction to be in contact with the inner wall of the circular tube, the sliding block 6 is in a circular truncated cone shape, and the diameter of one end, close to the supporting tube 4, of the sliding block 6 is smaller than that of one end, close to the driving module 7, of the sliding block 6.
