Description

Technical Field

[0001] The invention relates to the technical field of magnetic core tube welding, and in particular provides an electromagnet magnetic core tube welding positioning device. Background Art

[0002] An electromagnet is a device that generates electromagnetic field and thus motion through electric current. By controlling the current, the strength, presence, and direction of the electromagnet's magnetism can be controlled. Electromagnets are often used in environments where electric current is required to generate mechanical motion or maintain mechanical state, such as cranes, automated control equipment, and magnetic levitation trains. They have a wide range of applications in mechanical, electrical, and industrial production fields. The magnetic core tube is the core component of the electromagnet. The magnetic core tube is divided into two parts: the iron core and the guide sleeve. The existing processing technology for the magnetic core tube is to use a CNC lathe to process the iron core and the guide sleeve separately, and then weld the iron core and the guide sleeve into one by brazing the magnetic isolation ring.

[0003] Patent publication number CN110181202A discloses an automatic brazing device for magnetic core tubes. The device also includes a loading and unloading mechanism, a clamping mechanism, and a heating device. The loading and unloading mechanism comprises a three-dimensional movable slide mechanism, to which a rotary cylinder is fixedly connected, and to which two sets of parallel pneumatic fingers are fixedly connected. The clamping mechanism includes a fixed centering mechanism and a movable centering mechanism. The fixed centering mechanism includes a centering spindle with a conical head, the tail end of which is rotatably connected to a frame via a bearing. The movable centering mechanism includes a tailstock, a centering spindle with a conical head, which is rotatably mounted on the tailstock via a bearing. The tailstock slides on a tailstock rail and is connected to a tailstock drive cylinder. The heating device comprises a high-frequency heating coil heater. This device enables automatic brazing of magnetic core tubes.

[0004] After improving the electromagnetic iron core tube welding positioning device, this application uses automatic loading and unloading and automatic welding of the magnetic core tube, and uses a high-frequency heating coil for preheating before welding, which can ensure welding strength and improve welding quality. The exhaust hole can effectively discharge the expanded gas caused by the welding temperature rise in time. The splash-proof sleeve can prevent copper from splashing onto the iron core and affecting product quality. The automatic welding cleaning device can automatically clean the welding slag after the welding gun is moved above the spring. However, there is no special grinding device when copper welding the magnetic isolation ring to weld the iron core and the guide sleeve into one, so manual grinding is required before welding. Therefore, we proposed an electromagnetic iron core tube welding positioning device. Summary of the Invention
