A welding machine doing circular motion

Abstract

The invention relates to a welding machine doing circular motion, and belongs to the technical field of lithium argon battery manufacturing. The welding machine comprises a welding gun bottom frame, a fixed plate arranged on the welding gun bottom frame and a stepping motor fixed to the bottom of the fixed plate. An output shaft of the stepping motor penetrates through the fixed plate to be connected with the bottom of an R adjusting device, the top of the R adjusting device is connected with a spherical bearing, the spherical bearing is hinged to one end of a connecting rod, and the other end of the connecting rod is fixed to an adjustable connecting plate. The adjustable connecting plate is in sliding connection with an X-direction sliding rail, the bottom of the X-direction sliding rail is in sliding connection with two parallel Y-direction sliding rails through connecting blocks, the end of the X-direction sliding rail is connected with a welding gun seat, and a welding gun is fixed to the welding gun seat. The welding gun is driven by the motor to do circular motion, the rotating precision of the welding gun can be guaranteed, a processed battery is clamped and fixed by a clamp pushed by an air cylinder, the battery is clamped by the air cylinder, precision is greatly improved, and almost no displacement is generated.

Description

technical field [0001] The invention belongs to the technical field of lithium-argon battery manufacturing, and in particular relates to a circular motion welding machine. Background technique [0002] The welding of the existing lithium-argon battery shell and cover all adopts argon arc welding, and its specific manufacturing process is that the welding torch is fixed, and the battery is installed in the fixture and rotates around the axis. Due to the relative movement between the battery and the clamp and the electrode of the argon arc welding machine during the welding process of the battery, and the clamping of the battery should not be too tight, and the clamping is too tight for the operator to install, so it is very difficult to take the battery. Therefore, the welding machine is very prone to poor electrode contact during work. In addition, the way the battery is clamped makes the rotation accuracy of the battery impossible to be very high, so that the unqualified ra...

Problems solved by technology

Due to the relative movement between the battery and the fixture and the electrode of the argon arc welding machine during the welding process of the battery, and the clamping of the battery should not be too tight, and the operator will install the clamp too tightly, so it is very difficult to take the battery

Therefore, the welding machine is very prone to poor electrode contact during work. In addition, the way the battery is clamped makes the rotation accuracy of the battery impossible to be very high, so that the unqualified rate of battery welding remains high. In severe cases, it may even cause the welding machine to fail. normal work
