Frequency-variable and speed-adjustable gate-type automatic welding machine

Abstract

The invention relates to the technical field of welding machines, and discloses a frequency-variable and speed-adjustable gate-type automatic welding machine. The frequency-variable and speed-adjustable gate-type automatic welding machine comprises two gate posts, and the upper surfaces of the two gate posts are together fixedly connected with a connecting rod; the outer walls of the two gate posts are provided with through holes, the hole walls of the through holes are fixedly connected with first rolling bearings, and the inner walls of the first rolling bearings are fixedly connected with first threaded rods; the opposite ends of the two first threaded rods are fixedly connected with second rolling bearings in a sleeved manner, the outer walls of the second rolling bearings are togetherfixedly connected with a connecting cylinder, and the outer wall of the connecting cylinder is fixedly connected with the outer wall of the connecting rod; and the rod walls of the two first threadedrods are in threaded connection with threaded cylinders, and the lower surfaces of the threaded cylinders are fixedly connected with fixing plates. The frequency-variable and speed-adjustable gate-type automatic welding machine has the advantages that the welding efficiency of the gate-type automatic welding machine can be effectively improved, the use convenience of the gate-type automatic welding machine is improved, and meanwhile the labor intensity of working staff can be reduced.

Description

technical field [0001] The invention relates to the technical field of welding machines, in particular to a frequency conversion speed regulating door type automatic welding machine. Background technique [0002] Welding is the process of using various fusible alloys (solders) to join metal parts. The melting point of solder is lower than that of the material to be welded, so that the parts will end the welding through the intermolecular contact on the surface without being melted. The welding guarantees the continuity of the metal. Welding can be divided into soft welding and hard welding. Welding, soft soldering temperature is lower than 450°C, hard soldering is higher than 450°C, hard soldering is usually used for silver, gold, steel, copper and other metals, its solder joints are much stronger than soft soldering, and the shear strength is 20% of soft soldering ~30 times. The term soldering is commonly used for both of the above thermal connections, since in both cases...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a frequency conversion speed regulating door-type automatic welding machine, which can effectively improve the welding efficiency of the door-type automatic welding machine, and improve the convenience of use of the door-type automatic welding machine, and at the same time reduce the work The advantages of labor intensity and other advantages solve the problem that when the door-type automatic welding machine is used, the welding part cannot be fully welded due to the limitation of the installation position, and the welded parts need to be turned frequently, resulting in time-consuming and labor-intensive welding process, which affects the welding of the door-type automatic welding machine. Efficiency, and issues that affect the convenience of using the door-type automatic welding machine
