Description

Technical Field

[0001] The utility model belongs to the technical field of metal welding, and in particular relates to a metal welding processing tool. Background Art

[0002] Metal welding is a manufacturing or sculpture process of joining metals. During the welding process, the workpiece and the solder are melted or unmelted to form a direct weld of the materials. During this process, pressure is usually required to join the weldments.

[0003] A Chinese patent with application number CN202021586162.5 discloses a metal welding processing tool, including a base plate, a drive assembly is fixedly installed on the top of the base plate, the output end of the drive assembly is rotatably connected to a transmission assembly through a first gear pair, and an installation assembly is fixedly connected above the transmission assembly and located on the top of the base plate.

[0004] The above scheme locks and fixes the metal tube inside the mounting tube by fastening screws. However, in actual use, the locking method using fastening screws will cause the axis of the metal tube to deviate from the axis of the mounting tube. When the mounting tube rotates, the metal tube will rotate eccentrically, causing specific changes between the welding point and the welding processing head, thereby affecting the welding effect.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0010] Optionally, the driving mechanism includes a driving rod rotatably engaged with the two mounting plates on opposite sides, a reduction motor mounted on one side of the two mounting plates, and two transmission members mounted between the driving rod and the two rotating shafts, wherein the output end of the reduction motor is fixedly connected to one end of the driving rod. By setting up the driving mechanism, the fixed shell is driven to rotate the metal tube, which is convenient for processing.

[0011] The driving member of this embodiment includes a worm rotatably matched with the upper side of the fixed shell, and a worm wheel mounted on the threaded rod and matched with the worm. By providing the driving member, it is convenient to drive the conical block so that the conical block squeezes the seesaw, thereby clamping and fixing the metal pipe.

[0012] The upper side of the inner wall of the fixed shell of this embodiment is equipped with a limit rod, and a limit block fixedly connected to the threaded sleeve is slidably matched on the limit rod. The limit rod and the limit block are provided to guide the threaded sleeve.

[0013] The upper side of the adjusting shell of this embodiment is provided with a strip groove, and the upper side of the slider is threadedly matched with a locking bolt that slides with the strip groove. The locking bolt is provided to limit the slider and adjust the position of the fixed shell.

[0014] One side of the fixed shell of the present embodiment is provided with an inspection slot, and the inner wall of the inspection slot is provided with an inspection plate. By arranging the inspection plate, it is convenient to inspect and replace the internal structure of the fixed shell.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

The two arc-shaped clamping blocks move relative to each other, so that the metal pipe and the fixed shell rotate coaxially, so that when the metal pipe is welded, the distance between the welding point and the welding head is inconvenient, thereby improving the welding effect.
