Abstract

The utility model relates to an ejection mechanism of a nail gun. The ejection mechanism comprises an electromagnet (P) comprising a coil (6) arranged inside a slideway (2) and an iron core (5) arranged in the coil (6). The ejection mechanism is characterized in that one end of the iron core (5) of the electromagnet (P) is fixedly connected with a punch needle (4), and the slideway (2) is matched with the iron core (5) and the punch needle (4) which are fixedly connected to each other; and a magnetic pole and a permanent magnet (8) fixedly connected with the slideway (2) are respectively and axially arranged at one end of the coil (6) of the electromagnet (P) far from the punch needle (4). Compared with the prior art, in which the kinetic energy is directly provided by the compressed air, since the magnetic repulsion generated between the electromagnet and the permanent magnet directly provides kinetic energy for shooting of the nails (1) of the nail gun, both the transformation of energy and the energy transfer times are reduced, the overall volume of the nail gun can be greatly reduced, and the ejection mechanism is more convenient to carry and use.

Description

A kind of ejection mechanism that is used for ail gun

Technical field

The utility model relates to a kind of ejection mechanism, has related in particular to a kind of ejection mechanism that is used for ail gun.

Background technology

Pneumatic stapler is widely used in being connected and fixed of various sheet materials at present, its advantage is to have improved the efficient that is connected and fixed sheet material, its deficiency is that pneumatic stapler need be equipped with the air compressor use, because air compressor is by electric energy being converted into the kinetic energy of air, aerodynamic energy again Zhuan Yi Give ail gun dash pin, at last by towards pin that nail is knocking-on, energy conversion efficiency is not high, and air compressor volume, quality are bigger, move inconvenient.

Summary of the invention

The purpose of this utility model is:

Propose a kind of ejection mechanism that changes the ail gun of existing behaviour in service, reduce conversion, the transfer number of energy, improve energy conversion efficiency, thereby solve the deficiency that prior art exists.

In order to realize the purpose of the utility model: intend adopting following technology to realize:

Have: be arranged on slideway inside by coil and the electromagnet that iron core in coil constitutes is set, it is characterized in that: iron core one end of electromagnet and affixed towards pin, described slideway is complementary with affixed mutually iron core with towards pin; Magnet spool away from the end towards pin be provided with magnetic pole along electromagnet shaft to, and the permanent magnet affixed with slideway;

As preferably: described slideway is provided with spring washer near the inboard towards pin one end; Described permanent magnet is provided with cushion pad near an end of coil.

Compared with prior art, the beneficial effects of the utility model are:

Owing to use the electromagnet that constitutes by coil and setting iron core in coil, and be arranged on electromagnet coil away from directly providing kinetic energy for the ejaculation of ail gun nail towards the magnetic field repulsive force between the permanent magnet of pin one end, directly provide kinetic energy to compare with prior art by compressed air, conversion, the transfer number of energy have been reduced, and the overall volume of ail gun is reduced greatly, carry, use convenient.

The specific embodiment

Key of the present utility model is: have: be arranged on slideway inside by coil 6 and be arranged on the electromagnet P that the iron cores 5 in the coil 6 constitute, it is characterized in that: iron core 5 one ends of electromagnet P and affixed towards pin 4, described slideway 2 is complementary with affixed mutually iron core 5 with towards pin 4; It is axial along electromagnet P that the coil 6 of electromagnet P is provided with magnetic pole away from the end towards pin 4, and the permanent magnet 8 affixed with slideway 2; Described slideway 2 is provided with spring washer 3 near the inboard towards pin 4 one ends; Described permanent magnet 8 is provided with cushion pad 7 near an end of coil 6.

Described slideway 2 and are nonmagnetic substance (as: aluminium alloys) towards pin 4; Described cushion pad 7 can be a rubber; The slidably distance of described iron core 5 in slideway is 3 to 5 centimetres; Desirable 8000 Gausses of described permanent magnet 8 magnetic induction intensity; Described coil passes to 50 to 150 volts direct current, and it is opposite with permanent magnet 8 to make it produce magnetic direction, and the power on/off of coil 6 can use press button to control.

With reference to the accompanying drawings 1, when the coil 6 of electromagnet P is not switched on, iron core 5 with permanent magnet 8 since the magnetic field graviational interaction attract each other and be relative static; With reference to the accompanying drawings 2, behind coil 6 logical direct currents, iron core 5 produces the induced field opposite with the magnetic field of permanent magnet 8, and the magnetic induction intensity of the induced field that iron core 5 produces can be regulated by the input current that changes coil 6, so in the of short duration time, can make the huge repulsion of generation between iron core 5 and the permanent magnet 8, be that iron core is along permanent magnet opposite direction high-speed motion, then promote towards pin 4 bump nails 1, nail 1 can be injected in the plank, coil 6 outages; Iron core 5 knocks the spring washer 3 of short duration static or counter motions in back; because iron core 5 is less with permanent magnet 8 distances; magnetic field gravitation between them is enough to make iron core 5 to be returned to original state, and cushion pad 7 is used to protect permanent magnet 8, avoids permanent magnet 8 to be subjected to the direct bump of iron core 5 and magnetic weakens.

Because the utility model just launches the improvement that mechanism proposes at ail gun, the professional in present technique field also can easily understand its technical characterictic, so the structure of other parts of ail gun (as: control circuit, nail card) is not drawn in the accompanying drawings.

Claims

1. ejection mechanism that is used for ail gun, have: be arranged on slideway (2) inner by coil (6) and be arranged on the electromagnet (P) of iron core (5) formation in the coil (6), it is characterized in that: iron core (5) one ends of electromagnet (P) and affixed towards pin (4), described slideway (2) is complementary with affixed mutually iron core (5) with towards pin (4); It is axial along electromagnet (P) that the coil (6) of electromagnet (P) is provided with magnetic pole away from the end towards pin (4), and the permanent magnet (8) affixed with slideway (2).
