A drawing device for welding a positioning pin comprises a positioning seat plate, a positioning pin and a positioning pin drawing cylinder; the positioning seat plate is provided with a clamping pin guide groove, and the positioning pin is arranged on the clamping pin guide groove in an inward-outward sliding manner through a clamping guide slide block; and the power output end of the positioning pin drawing cylinder is connected with the positioning pin.
Description
Technical Field
The utility model belongs to the technical field of the welding locating pin frock technique and specifically relates to a pulling and drawing device of welding locating pin.
Background
In the prior art, in the welding process of a main limb and a connecting sleeve of a tower crane. The positioning pin is inserted into the fixed guide hole, and the connecting sleeve of the main limb penetrates into the positioning pin for welding. After welding, the positioning pin is difficult to pull out by pulling out the cylinder due to the thermal expansion effect and the welding deformation resistance. Most of the cases are performed by the worker using the hammer to shake and knock simultaneously, which wastes time and labor, damages the repeated positioning precision of the positioning pin and reduces the service life.
SUMMERY OF THE UTILITY MODEL
