Description

Technical Field

[0001] The invention belongs to the field of electric welding equipment, and in particular relates to electric welding equipment for manufacturing vehicle parts. Background Art

[0002] Electric welding machines use the high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the welding rod and the material to be welded, so that the contacted objects can be combined. Electric welding machines can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is DC power supply. They use the principle of inductance. The inductance will produce a huge voltage change when it is connected and disconnected. The high-voltage arc generated when the positive and negative poles are short-circuited for an instant is used to melt the solder on the welding rod, so that they can achieve the purpose of atomic combination.

[0003] Most traditional electric welding equipment for automotive parts cannot take into account the welding of the outer ring and inner ring of the ring-shaped parts. Usually two devices are required for welding. Some ring-shaped parts with larger diameters or some ring-shaped parts with thicker thickness usually need to be fixed by double-sided welding in order to increase stability. When welding the inner ring, it is usually necessary to clean and rub the gap before welding to avoid the outer ring welding affecting the inner ring welding effect. The welding of a whole ring part requires multiple steps, which wastes manpower and material resources and is inefficient. Summary of the invention

Driving the two cylinders to rotate synchronously is the prior art and will not be described in detail.

At this time, the rotating threaded rod is used to drive the threaded block to move until the extension rod and the shell are driven to expand outward and contact the inner wall of the annular part. Then the dual-axis motor is started and the friction roller is driven by the rotating shaft to frictionally clean the weld of the annular part. During the cleaning process, a barrel with fan blades is used to blow away the dust generated by friction. After cleaning, the welding gun is used to weld the inner ring of the annular part.

[0036] Working principle: When using the present invention, the annular parts are clamped on two clamping devices. Since the two clamping devices are horizontal and the two rotating sleeves 6 are circularly in a straight line, the alignment step is omitted. Only two annular parts need to be placed on the two rotating sleeves 6, and then the single-sided threaded disk 5 and the single-sided threaded disk 5 are rotated to drive multiple clamping rods 13 to be inserted into the rotating sleeve 6 to fix the annular parts. After fixation, the locking bolt 14 is used to fix the rotation of the double-sided threaded disk 2 and the single-sided threaded disk 5, so as to form a stable clamping state, and then one of the support parts 7 that is slidably connected to the base 1 is pushed until the two annular parts are aligned and contacted, and then the lateral adjustment of the threaded rod 4 and the power box 19 is used to move the welding gun 905 to the joint for welding.

The welding gun 905 and the shell 904 are pushed to the weld of the annular part by the telescopic rod 18. At this time, the rotating threaded rod 17 is used to drive the threaded block 901 to move until the extension rod 903 and the shell 904 are driven. After expanding outward and contacting the inner wall of the ring part, the dual-axis motor 906 is started to use the rotating shaft 911 to drive the friction roller 912 to frictionally clean the weld of the ring part. During the cleaning process, the barrel 908 with fan blades is used to blow away the dust generated by friction. After cleaning, the welding gun 905 is used to weld the inner ring of the ring part. The whole process does not require secondary clamping and can be completed by one device. During the process, the barrel 908 with fan blades can be set to clean the pretreatment before the inner ring welding. The overall operation is simple and efficient.
