Description

Technical Field

[0001] The utility model relates to the technical field related to welding processing, in particular to a clamping tool used for welding processing. Background Art

[0002] The welding process converts the energy output by the welding energy equipment into welding heat, and continuously feeds in welding materials. At the same time, the machine head itself moves forward to achieve welding. The electric welding tongs used for manual arc welding must continuously feed the welding rod downward manually as the welding rod melts, and move forward to form a weld. The automatic welding machine has an automatic wire feeding mechanism and a machine head walking mechanism to move the machine head forward. There are two commonly used machine heads: trolley type and hanging type. The welding machine head for resistance spot welding and projection welding is the electrode and its pressurizing mechanism, which are used to apply pressure and power to the workpiece.

[0003] In existing welding processes, a complex fixture with multiple different clamping mechanisms and positioners is installed on the clamp body. Each time a different welding product is clamped, the complex fixture needs to be adjusted. If the clamping mechanism and the positioner are adjusted incorrectly, the welding product may be deformed or fall off. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping tool for welding processing to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An airbag clamping assembly is mounted on the workbench;

[0008] A tool clamping assembly, arranged on the tooling table;

[0009] Among them, a clamping platform is movably installed on the top of the tooling table, tooling movable rails are arranged on both sides of the clamping platform, an external clamping ring is movably installed on the inner side of the tooling movable rail, a pneumatic clamp end is installed at the front end of the external clamping ring, the pneumatic clamp end is connected to the air pressure tube group, and a placement frame is fixed in the middle of the clamping platform.

[0010] The clamping tool used for welding processing as described above: the pneumatic clamp end passes through the inside of the clamping table through an external clamping ring.

[0011] The clamping tool used for welding processing as described above: the clamping table is slidably installed on the tooling table through the tooling moving rail.

[0012] The clamping tool used for welding processing as described above: the airbag clamping assembly includes a merging ring movably installed on the inner side of an external clamping ring, and airbag clamps are movably installed inside the merging ring and the external clamping ring.

[0013] The clamping tool for welding processing as described above: the airbag clamp is driven through the merging ring and the inside of the external clamping ring by the pneumatic clamp end.

[0014] The clamping tool used for welding processing as described above: the tool clamping assembly includes a lower fixing frame movably installed at the bottom end of the clamping table, and the clamping table is threadedly connected with fixing bolts around it.

[0015] The clamping tool for welding processing as described above: the lower fixing frame is threadedly fastened on the clamping table by fixing bolts.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the external clamping ring and the merging ring are clamped inside the placement frame by pneumatic collision of the airbag clamp, so as to clamp the welding products inside the placement frame; the external clamping ring and the merging ring can be deformed and clamped on the outside of welding products of different shapes; the airbag clamp pneumatically expands the external clamping ring and the merging ring and unfolds them inside the placement frame; a plurality of different clamping mechanisms and positioners are installed on the clamp body during welding processing; the external clamping ring and the merging ring are folded and unfolded to clamp on the outside of the welding product; each time a different welding product is clamped, the external clamping ring and the merging ring do not need to be adjusted and clamped.

[0017] The external clamping ring and the merging ring are movably installed around the welding product, and then are pneumatically expanded by the airbag clamp to push and clamp around the welding product. There is no need to adjust the complex clamp each time a different welding product is clamped. When the clamping mechanism and the positioner are adjusted incorrectly, the external clamping ring and the merging ring are deformed and installed on the outside of the welding product, and then are pneumatically expanded by the airbag clamp to clamp it, avoiding deformation or falling off of the clamp.
