Problems solved by technology

[0003] However, when the workpiece is welded by counter-electrode resistance welding, the workpiece is easily biased under the pressure of the upper electrode and the lower electrode.
Especially thin wires with circular cross-sections are prone to slipping during welding, which can easily cause misalignment and affect the quality of welding
For larger workpieces (>5mm), the deviation caused by pressure is not obvious, but for some special small-sized workpieces, such as brushes in motors (<1mm), metal filaments (10-100μm), etc., Alignment errors can seriously affect the performance of the final product
[0004] The existing method generally controls the relative position of the workpiece to be welded by manual adjustment, so the work efficiency is low, and the quality of the welded product cannot be guaranteed, which seriously affects the production efficiency

Abstract

The utility model relates to a jig for quickly aligning resistance welding workpieces, which belongs to the technical field of micro resistance welding. The upper part of one end of the fixture housing is detachably and fixedly connected to the adjustable deck, and the upper part of the other end of the fixture housing is slidingly connected with two positioning baffles arranged side by side through an adjustment mechanism. The set workpiece conductive base, the adjustment mechanism and the workpiece conductive base are all arranged inside the fixture shell, the workpiece conductive base is located in the middle of the fixture shell and its lower end is detachably and fixedly connected to the fixture shell. The invention can realize rapid positioning of workpieces to be welded, prevents deviation during the electrode resistance welding process, can be used for workpieces of various sizes, and does not need to be re-aligned after replacing workpieces of different sizes, which is beneficial to improving the resistance welding efficiency of the workpieces.

Description

technical field [0001] The invention relates to a jig for quickly aligning resistance welding workpieces, belonging to the technical field of micro resistance welding. Background technique [0002] The main principle of counter-electrode resistance welding is to press the two workpieces to be welded by the upper electrode and the lower electrode of the resistance welding machine and pass current, and use the Joule heat generated between the workpieces to locally heat the workpieces, and plastic deformation and atomic diffusion will occur between the workpieces And realize the connection. Electrode resistance welding is suitable for workpieces of various materials and shapes, and can connect metal wires (such as copper wires, nickel alloy wires), strips (such as nickel strips), sheets (such as copper foils), etc. [0003] However, when the workpiece is welded by counter-electrode resistance welding, the workpiece is easily biased under the pressure of the upper electrode and...
