Precision welding machine

Abstract

The invention provides a precision welding machine which comprises a body. A spindle box and a welding power source are disposed on the body. A three-jaw chuck is fixed on a spindle outside the spindle box. The spindle is driven to rotate by a spindle motor. A transverse guide rail used for controlling a welding torch to move back and forth is disposed on the body. A slider is disposed on the transverse guide rail. A welding torch fixing plate is arranged at the front end of the slider. A carriage is a bent plate in an L shape. The bottom of the moving carriage is fixed on a screw through a feed screw nut. A screw stepping motor is arranged at one end of the screw. The spindle motor is a spindle stepping motor. A guide rail stepping motor is disposed on the transverse guide rail. The precision welding machine has the function of precision welding and is simple in structure and convenient to operate, product quality is stable, and production efficiency is high.

Description

technical field [0001] The invention technology relates to a kind of metal automatic welding equipment, especially suitable for precise circular seam automatic welding of medium and small workpieces. Background technique [0002] Tubular metal workpieces are used extensively in some industrial products. Circumferential seam welding is required during the machining of these workpieces. For precision workpieces, precision welding is required, so as to ensure the quality of the workpieces, thereby ensuring the quality of industrial products. For example, the shell packaging welding of micro refrigerators, the girth welding of bellows flanges, and the packaging welding of sensors. The traditional welding method is manual welding, and the quality of the welded workpiece depends entirely on the technical level of the staff and the working state during work. There are many uncertain factors in product quality, and the quality consistency of batches of products is poor. The labo...

There are many uncertain factors in product quality, and the quality consistency of batches of products is poor

The labor intensity of the staff is high and the work efficiency is low. The existing circular seam welding equipment is generally welded by a positioner. Since the motor of the positioner is an ordinary motor, it is impossible to accurately control the rotation angle of the workpiece; the rotation accuracy is relatively low. Low, the selected power supply is also a common power supply, this kind of equipment is only suitable for the welding of common workpieces, and cannot complete the precision welding of small and medium workpieces
