Background technology
In existing frequency converter production technology, welding rectifier module and inversion module on power panel are with seven screws
Power panel and rectification module and inversion module are first all positioned on a heat sink.Carry out anterior fastening simultaneously again,（If screw is
Disposably fasten one by one, the component filled after causing can because hole site not pair can not install）.Treat that component is all welded
Afterwards, then again previously peaceful seven tight screws need to all be unloaded down, removes power supply board component, carry out subsequent detection and two sides is brushed
The work such as three-proofing coating.Because used in this seven screw positioning and fastening and unloading the required time down, total welding is just occupied
Most time of process, while screw fastens and also to damage many radiators during unloading（Damage the silk tooth of radiator）
Therefore, to there is production efficiency very low for prior art, wastes the defect such as serious, it is necessary to improve.
Utility model content
The utility model is fixed for the pressurization of frequency converter rapid welding there is provided one kind in order to solve the problem of prior art is present
Position pin, the position of wiring board and other components can be flexibly lived surely, allows wiring board not move, pin welds more accurate, work
Make more efficient.
The technical solution adopted in the utility model is as follows, and one kind is used for frequency converter rapid welding pressurization pilot pin, including：
Needle guard, its upper end has the first internal thread；
Needle body, is placed in needle guard and is stretched out from the lower section of needle guard, have compression wall at the lower section of the needle body；
Screw rod, its two ends have in the first external screw thread and the second external screw thread, first external screw thread and described first respectively
Screw thread matches；
Spring, is placed in needle guard, and positioned between needle body and screw rod.
Preferably, the needle body includes needle section and shank, and the needle section and shank are detachably connected, the needle section
With syringe needle location division and limiting section.
Preferably, the diameter of the limiting section is more than the diameter of the syringe needle, and the lower surface of limiting section is the pressurization
Wall.
Preferably, the needle section and shank are connected through a screw thread.
Preferably, the needle section is provided with the 3rd external screw thread, and the shank is provided with the matched with the 3rd external screw thread
Two internal threads.
Preferably, the upper end of the needle body and the lower end of screw rod are respectively provided with spring retainer lead.
The utility model has advantageous effect in that：The utility model smart structural design, the pilot pin assembled,
Two nuts are loaded onto on second external screw thread of screw rod, then will be fixed on by nut above whole pilot pin on pressing plate, Gu
After setting, by pressing plate to driving in whole positioning needle movement, the positioning hole of the needle section insertion wiring board of pilot pin, under press through
Cheng Zhong, compression wall withstands wiring board or electronic component, and needle body is no longer moved, and needle guard continues to move downward, and needle body is placed in needle guard
Inner compression spring, flexibly complete pilot pin and the multiple spot of wiring board or electronic component pressurizeed simultaneously positioning, therefore, positioned
Pin can be adapted to the positioning compression effect of the wiring board or electronic component of different dynamics requirements, and adjust needle body if desired to circuit
The compression intensity of plate, then can screw the first screw thread of screw rod and change the elastic force of spring.
