Detailed Description

First, it should be understood by those skilled in the art that the embodiments described herein are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1 and 2, the utility model provides a welding bench, including table 1, running-board 3, first pivot 21, second pivot 22, two third pivots 23 and two centre gripping pipes 4. The work table 1 comprises a table top 11 and two table legs 12. Two support plates 112 are welded on the upper surface of the table plate 11, an opening 111 is formed in the table plate 11, and the opening 111 is located between the two support plates 112.

The first rotating shaft 21 is rotatably connected with the two table legs 12; the second rotating shaft 22 is rotatably connected with the two support plates 112; the two third rotating shafts 23 are located between the two support plates 112 and are respectively connected with the two support plates 112 in a rotating manner. The first rotating shaft 21 is horizontally disposed, and the second rotating shaft 22 and the third rotating shaft 23 are parallel to the first rotating shaft 21. The third rotating shafts 23 are located above the second rotating shafts 22, and the two third rotating shafts 23 are coaxially arranged. The first rotating shaft 21, the second rotating shaft 22 and the third rotating shaft 23 are located in the same vertical plane. The first rotating shaft 21 and the second rotating shaft 22 are in transmission connection with a belt pulley through a belt; the second rotating shaft 22 and the two third rotating shafts 23 are in transmission connection through a belt and a belt pulley. The belt connecting the first rotating shaft 21 and the second rotating shaft 22 passes through the opening 111 of the table 11.

The pedal 3 is connected to the first rotating shaft 21 through a one-way bearing. Therefore, when the pedal 3 is rotated back and forth around the first rotating shaft 21, the first rotating shaft 21 is rotated only in a single direction. The clamping tube 4 is connected with the third rotating shaft 23 through a spline.

The two clamping pipes 4 are respectively and coaxially connected with the opposite ends of the two third rotating shafts 23, and the clamping pipes 4 are used for clamping the pipe 5 to be processed. Specifically, the clamp tube 4 includes a connecting portion 41, a first clamp portion 42, and a second clamp portion 43. The connecting portion 41 is connected to the third rotating shaft 23 by a spline. The second clamping portion 43 is a portion cut off from the clamping tube 4, the first clamping portion 42 and the second clamping portion 43 are opposite half-tube structures, and the clamping tube 4 can clamp the to-be-processed tube 5 by using the first clamping portion 42 and the second clamping portion 43 to be opposite. One end of the second clamping part 43 is hinged with one end of the first clamping part 42, the other end of the second clamping part 43 and the other end of the first clamping part 42 are respectively welded with a connecting plate 44 which vertically extends upwards, and the two connecting plates 44 are detachably connected through bolts.
