Abstract
The utility model relates to a machine head of a spot welding machine, and the machine head is provided with a pressure sensor and is applicable to various spot welling machines needed to be accurately control the welding force. A metal component with the pressure sensor and a shape changing cavity is arranged inside the machine head. The pressure sensor is arranged on the outer side surface of the shape changing cavity. The metal component is respectively connected with a draw rod providing the welding force and a sliding shaft by the two metal clipping blocks of the both ends of the metal component. The sliding shaft is connected with an electrode clipping head, and an electrode is arranged on the electrode clipping head. The signals of the pressure sensor are connected with a CPU interface after the signals are carried through amplifying management. The machine head of the electron spot welding machine can accurately control the welding force, can enhance the performance of the electron spot welding machine, and can ensure the welding quality of the electron spot welding machine.
Description
Technical field
The utility model relates to a kind of mash welder head, and being applicable to needs accurately to control the mash welder that weld force is carried out accurate welding.
Background technology
Mash welder belongs to electric resistance welding, and welding current (or voltage), weld interval and weld force all will be set when carrying out electric resistance welding spot welding.The conventional art weld force all is to be provided by the compression spring, because the structure and the process technology of spring, when many spring compression same distance, the error of every spring compression stress is bigger; Simultaneously, the compression weld force that spring provided can not directly show.And instrument, instrument and and the manufacturing of electronic devices and components, need the miniature workpiece of welding, the thickness of its workpiece is often less than 0.1mm, carry out such precision welding, except will accurately controlling the electrical quantity, also to accurately control weld force, obviously, mash welder uses the compression spring that weld force is provided, and is difficult to satisfy the instructions for use of accurate welding.
Summary of the invention
The purpose of this utility model provides a kind of mash welder head, can accurately control and shows weld force, is applicable to that various need provide the mash welder of accurate weld force.
The hardware that band pressure sensor and deformation chamber are arranged in the utility model mash welder head, pressure sensor is positioned on the lateral surface in deformation chamber, the two ends of this hardware by two metal fixture blocks respectively with the pull bar that weld force is provided be connected with slide-bar, slide-bar is connected with terminal clamp, and electrode is installed on the terminal clamp.The external pressure sensor signal treatment circuit of pressure sensor, this signal processing circuit mainly are converted into electric signal to detected deformation power and amplify, and are connected with cpu i/f, input control circuit, the parameter display circuit etc. in addition that are connected with CPU.During work, at first the button of required weld force at input control circuit presetted, and show at display circuit by CPU; External force is by pull bar tractive metal fixture block, slide-bar can very smooth-going area moving electrode chuck and electrode move down, make electrode and workpiece that certain contact force (being weld force) be arranged, the reaction force of contact force and traction force acting in conjunction, make sensitive deformation chamber produce deformation, deformation power is detected by pressure sensor, because pressure sensor signal treatment circuit and display circuit and input control circuit are all handled by CPU, when deformation power reaches default definite value, power switch triggers, and the accuracy of welding needed electric current and guaranteeing weld force is provided for electrode.
Adopts pressure sensor control weld force, simple in structure and accuracy is high, relative error can reach 1 ‰.This head can be assemblied in any type welding machine in the mash welder that needs accurate control weld force.
Description of drawings
Fig. 1 is the utility model mash welder handpiece structure figure.
The specific embodiment
