The utility model is composed of magnetic body (20) driven by electromagnetic coil curls (8) and (9) in a handle shell (7), and a shuttle frame body. The front end of the utility model is provided with the impact electromagnetic coil curl (8), and the back end is provided with the resetting electromagnetic coil curl (9). Firing pins (5) are arranged on the connected bases (18) of firing pins, and the connected bases (18) of firing pins extend in an adjusting cover plate (2) and a shuttle frame base (3). A stop block (16) and a positioning handle (15) are used for locking a shuttle frame (13) and a push and pull shuttle cover plate (14), and a switch is used for controlling a power supply. The utility model has the advantages of safe operation and convenient use and provides a practical electric tool for building, finishing and decorative work.

Description

Electromagnetic nail gun

The utility model electric tool, particularly a kind of electromagnetic nail gun that is used for the fitting-out work ailing.

At present, pneumatic nail gun is often adopted in the ailing operation in the fitting-out work of building trade, and this nail rifle uses airduct to link to each other with compressed gas source with joint, reaches certain working pressure, can use the nail rifle.This nail rifle needs supporting use air compressor as source of the gas, and tracheae can not be long, move and transportation all very difficult, using building-site to make troubles to fitting-out work.

The purpose of this utility model is to overcome above technical deficiency, provides a kind of impact energy high electromagnetic nail gun.

Task of the present utility model is, the magnetic kinetoplast that electromagnetic nail gun is driven by the solenoid in handle body, the housing, and the anterior shuttle support body of installing is formed.The magnetic kinetoplast is installed in the non magnetic guide pipe of solenoid, front end is for impacting solenoid, when impact stroke, work, the rear end is the solenoid that resets, in backstroke work, on the joining firing pin base firing pin is installed, stretch in that housing is anterior and the adjustment plate that has the nail chamber is installed and is had in the shuttle frame base of indent, the vertical connection on the straight nail shuttle frame that has the nail groove installed nail hitting, upward answers push-and-pull shuttle cover plate.On the adjustment cover plate, have the oval hole of adjusting, adjust control nail hitting length, fix by the adjustment screw.

Push-and-pull shuttle cover plate topped on straight nail shuttle frame is by the position fixing handle locking; Removable straight nail shuttle frame, push-and-pull shuttle cover plate are applicable to various working environment operations by the scotch locking.

On handle housing, install to impact limit switch, reset switch, plate machine, hand admire formula switch, power switch, control electromagnetic nail gun power work.

Electromagnetic nail gun is connected to the alternating current circuit by rectifier, and the magnetic kinetoplast is directly driven by solenoid, and the magnetic kinetoplast is moved back and forth, and drives the direct attack pin of installing in the straight nail of the firing pin bump shuttle frame and hammers into by the nail thing.One, impact stroke are that full-wave rectification produces than high-intensity magnetic field accelerated motion, and return stroke is that impact that halfwave rectifier produces is half magnetic field of all-wave, reduces the energy loss that resets; Its two, the energy loss that adopts direct current not cause because of change in polarity.

Specify with embodiment below in conjunction with accompanying drawing.

Among Fig. 1 electromagnetic nail gun in handle housing (7) by solenoid (8), (9) the magnetic kinetoplast (20) of Qu Donging, the anterior shuttle support body of installing, the electromagnetic nail gun of forming, in solenoid (8), (9) in the non magnetic guide pipe (19) magnetic kinetoplast (20) is housed, front end is for impacting solenoid (8), the rear end is the solenoid that resets (9), joining firing pin base (18) is gone up firing pin (5) is installed, stretch into housing (7) is anterior the adjustment lid that has the nail chamber is installed is pulled (2) and have the school frame of indent at the bottom of in (3), the vertical straight nail shuttle frame (13) that has the nail groove that connects is gone up push-and-pull shuttle cover plate (14) again, removable straight nail shuttle frame (13), push-and-pull shuttle cover plate (14) is formed the shuttle support body, by scotch (16), position fixing handle (15) locking.Be equipped with on the handle housing of electromagnetic nail gun (7) and impact limit switch (6), reset switch (10), trigger (21), the hand formula switch (22) of admiring, power switch (24), control power work.

Fig. 2 is the circuit theory diagrams of electromagnetic nail gun.

During electromagnetic nail gun work, connect power supply, electric current passes through R ₁, LED ₁, make LED ₁Luminous display power supply on.The handle housing (7) of holding with a firm grip, power switch K ₁The conducting electric current passes through R ₂, LED ₂Make luminous second tube sheet LED ₂Luminous, demonstration can be worked, and presses plate machine (21) and makes K ₂Electric current passes through R during action ₃, K ₂, K ₃Trigger controllable silicon T ₁Make T ₁Conducting is through rectification circuit L ₁Rectification, magnetic kinetoplast (20) is moved in non magnetic guide pipe (19) by solenoid (8), (9), and electromagnetic impact coil (8) is worked when impulse stroke, and solenoid (9) is worked when backstroke.Magnetic kinetoplast (20) drives the direct attack nail of installing in firing pin (5) the bump straight nail shuttle frame (13) (1), hammers into by the nail thing, and impulse stroke finishes.Limit switch K ₃Disconnect, make T ₁The triggerless outage, magnetic kinetoplast (20) reset switch K ₄Closed.

When unclamping trigger (21), K switch ₂Reset, trigger current is through R ₃, K ₂, K ₄Trigger T ₂Conducting makes resetting coil (9) drive magnetic kinetoplast (20) in the non magnetic guide pipe (19) and returns and reset limit switch k ₄Disconnect T ₂Triggerless is turn-offed, and magnetic kinetoplast (20) resets K switch ₃Closure moves in circles, during release handle, and power switch K ₁Automatically shut down.

The electromagnetic nail gun technical performance:

1, is suitable for voltage 220V ± 10%
