Abstract

The invention relates to a kind of head of all kinds of mash welder which can control welding power exactly. The head consists of metal unit that include electrical pressure transducer and changing lumen. The transducer is fixed outside the lumen. The metal unit connects to the drawbar and sliding bearer, which both supply drawing force for welding. The sliding bearer connects to tong hold of the electrode. The electrode is fixed to the electrode tong hold. Message of the pressure transducer is magnified and then connected to CPU. The welding head can control the welding power exactly and improve the performance of the welder, ensure the welding quality.

Description

A kind of mash welder head with pressure sensor
Technical field
The present invention relates to a kind of mash welder head, 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 invention is to provide a kind of mash welder head, can accurately control and show weld force, be 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 mash welder head of the present invention, pressure sensor is installed in 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 mash welder handpiece structure figure of the present invention.
In Fig. 1, the pressure sensor 1 of welder head of the present invention is installed in the inferolateral surface in deformation chamber 10, the hardware 2 of having formed band pressure sensor and deformation chamber, hardware 2 is connected with slide-bar 6 with the pull bar 5 that weld force is provided respectively by two metal fixture blocks 3,4, slide-bar is connected with terminal clamp 8, electrode 9 is installed on the terminal clamp, and line sliding bearing 7 is installed on the slide-bar.Pressure sensor is circumscribed with the pressure sensor signal treatment circuit, and is connected with cpu i/f by the pressure sensor signal treatment circuit; Input control circuit, the parameter display circuit in addition that are connected with CPU.
