Present in the problems referred to above.
The technical solution of the utility model is：
A kind of probe of detection stud weld seam degree of fusion, comprising negative contact terminal, insulating sleeve, positive contact, truncated cone spiral
Compression spring, insulator foot, positive signal wire, negative signal wire, workpiece and welding screw, the negative contact terminal are annular
Contact, positive contact are dish type contact, and small end and the positive contact of truncated cone spiral compression spring are interconnected, big to hold and insulation bottom
Seat is interconnected, and positive contact, truncated cone spiral compression spring are arranged on the inside of insulating sleeve, and insulator foot is arranged on insulation sleeve
The bottom of cylinder, negative contact terminal are arranged on the outside of insulating sleeve, and positive signal wire passes through insulator foot center hole and truncated cone
Interconnect with positive contact behind the inside of spiral compression spring, negative signal wire is after outside is fastened with insulating sleeve
Interconnect with negative contact terminal, insulating sleeve back-off is arranged on and is welded with the workpiece of welding screw, and negative contact terminal is mutual with workpiece
Contact, contacts with each other at the top of positive contact and welding screw.
The negative contact terminal, the material of positive contact are copper.
The distance of the lower surface of the lower surface of the positive contact to negative contact terminal it is less than the length of welding screw 5 millimeters with
On.
The beneficial effects of the utility model are：Using the structure of both positive and negative polarity contact integration, touch from positive contact and negative pole
Holding wire is drawn respectively to be connected with detecting instrument on head, and in addition the contact form of instrument and detected pieces is connect by contacting the face of being changed to
Touch, during measurement contact area is big, uniform force, simple structure, flexible operation, overcome split type measuring pen or measured material
Many deficiencies, detection efficiency is high, error is little, be suitable on production line and operation field high-volume quick detection.
