Insulating nozzle of welding gun

Abstract

An insulating nozzle of a welding gun comprises an outer nozzle pipe, an inner nozzle pipe and an insulating piece, wherein the insulating piece is injection-moulded between the inner nozzle pipe and the outer nozzle pipe; the axes of the outer nozzle pipe, the inner nozzle pipe and the insulating piece coincide; the inner end surface of the insulating piece extends to the inner end of a necking cavity of the outer nozzle pipe; and the outer end surface of the insulating piece axially extends outwards relative to one end surface of the inner nozzle pipe. The insulating piece is combined with the outer nozzle pipe and the inner nozzle pipe by an injection moulding technology, so that the loss of the insulating piece can be reduced, and damage to the welding gun caused by the reason that an operator forgets to mount the insulating piece or the insulating piece falls by accident is avoided; during a using process, the insulating nozzle is easy to mount, stable in mounting structure and difficult to damage; the insulating nozzle has a good insulating effect, and the problem that splashing particles are accumulated between the outer nozzle pipe and the insulating piece is avoided; and the internal structure of the nozzle is more compact, and more splashing particles can be stored in the insulating nozzle, so that the gun cleaning frequency is reduced, and the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of welding torches, in particular to an insulating nozzle for welding torches. Background technique [0002] As a welding consumable, the welding torch has a service life that determines the production cost. At present, the nozzle and the insulator used on many welding torches are separated, and each is a consumable, so the replacement of the separated structure is relatively complicated and easily damaged. During automatic welding, the welding torch cleaning action of the robot is generally completed by automatic equipment, and the insulating parts are easily damaged during the cleaning process. In the case that the nozzle and the insulator are of a separate structure, once the operator forgets to install it, it is very easy to cause damage to the welding torch. [0003] Due to the related structures of nozzles commonly used in the market today, such as figure 1 As shown, it includes a contact tip 20 , a...

AI Technical Summary

Problems solved by technology

[0004] In view of the defects caused by the split structure of the current welding torch nozzle and insulating parts, the invention provides a welding torch insulating nozzle, which is easy to install, stable in structure, not easy to damage, good insulator effect, and no splash particles will appear between the outer tube of the nozzle and the insulator. The problem of accumulation between the insulating parts can also make the internal structure of the nozzle more compact, which can accommodate more splash particles, increase the interval between gun cleaning, and effectively improve production efficiency
