Welding device capable of preventing welding quality from being affected by infirm fixation of object

Abstract

The invention relates to the technical field of high-frequency welding machines, and discloses a welding device capable of preventing welding quality from being affected by infirm fixation of an object. The welding device comprises a base, a support column is fixedly connected to the top of the base, a workbench is fixedly connected to the top of the support column, a crank is movably connected to the right side of the workbench, and the top of the workbench is movably connected with a fixing frame. According to the welding device capable of preventing the welding quality from being affected by infirm fixation of the object, the crank is rotated, a driving bevel gear drives a driven bevel gear to rotate at the moment, a supporting rod further drives a welding head to move up and down, and the effect of rapidly and conveniently adjusting the height of the welding head is achieved. When a rotating disc is rotated, a second threaded rod drives a sliding block to move front and back, the fixing frame further drives a limiting block to move front and back, a knob is rotated, a first threaded rod drives the limiting block to move left and right, and the effect that workpieces of different specifications can be stably clamped is achieved.

Description

technical field [0001] The invention relates to the technical field of high-frequency welding machines, in particular to a welding device that prevents unreliable fixing of objects from affecting welding quality. Background technique [0002] The high-frequency welding machine can not only be used for welding various metal materials, but also can be used for diathermy, smelting, heat treatment and other processes. Its working principle is mainly to convert low-frequency alternating current into high-frequency alternating current, and then use the principle of electromagnetic induction to convert it into a high magnetic field, and act on the metal object in the magnetic field, then use the turbine effect to generate induced current, and finally use the current thermal effect to generate heat. [0003] During the welding process of the existing high-frequency welding machine, its positioning and fixing device can only clamp the position of a single specification, and then whe...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a welding device that avoids unreliable object fixation from affecting the welding quality. It has the advantages of stable clamping of workpieces of different specifications and quick and convenient adjustment of the height of the welding head, which solves the problem of During the welding process of the existing high-frequency welding machine, its positioning and fixing device can only clamp the position of a single specification, and then when processing workpieces of different specifications, it is easy to clamp the workpiece, thus affecting the quality of welding , and the height adjustment of the existing high-frequency welding machine is inconvenient. When welding workpieces of different heights, it may take a long time, thereby increasing the production cost.
