Welding and weld mark polishing device for machining of electrical heated tube

Abstract

A welding and weld mark polishing device for machining of an electrical heated tube comprises a box, wherein the bottom of a cavity of the box is fixedly connected with a damping device; the side, which is away from a supporting block, of a supporting table is fixedly connected with a lifting device; an output shaft of a second motor is rotatably connected with a polishing wheel through a coupler;an output shaft of a third motor is rotatably connected with a three-jaw chuck through a coupler; the top of the side, which is positioned on the right side of the polishing wheel and is close to thegrinding wheel, of the supporting rod is rotatably connected with a fixing device; the middle of the top of the cavity of the box is fixedly connected with a vertical movement device; and the side, which is away from the top of the cavity of the box, of the vertical movement device is fixedly connected with a welding box. The invention relates to the technical field of electrical heated tube machining equipment. Any types of electrical heated tubes can be fixed, machining equipment does not need to be changed frequently, the cost is saved, industrial development is facilitated, a point of weld can be found automatically, manual operation is not required, the device is safe and reliable, the production efficiency is improved, the time is saved, and thus, market requirements are met.

Description

technical field [0001] The invention relates to the technical field of electric heating tube processing equipment, in particular to a welding and weld mark grinding device for electric heating tube processing. Background technique [0002] Electric heating tube, also known as heating tube, heating tube, scientific name tubular electric heater element, is to put a coiled heating wire in a metal tube, and fill it with good heat resistance, thermal conductivity and insulation around it and in the gap. Non-toxic insulating powder, the two ends of the heating wire have lead-out rods or lead-out wires. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. It is widely used in various saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot pressing molds and other devices. The elect...
