Abstract

The utility model discloses a clutch type blank shooting prevention nail-shooting gun of a cam, which comprises a housing case, and a nail-shooting firing pin which is arranged in a compression air cylinder at the right side of a gun body in the hosing case, wherein a transmission ratchet wheel driven by a motor is arranged at the left end part of the gun body, the transmission ratchet wheel is in transmission connection with an eccentric cam by a pin shaft which is arranged on the end surface of the transmission ratchet wheel, the eccentric cam is connected with one end of a steel wire rope, the other end of the steel rope is connected with the left end of the nail-shooting firing pin, the nail-shooting firing pin can be moved to a shooting position at the left end from a nail shooting position at the right end due to winding of the eccentric cam on the steel wire rope, the gun can be rotated to a pre-set position by the pin shaft, the pin shaft and the eccentric cam are tripped, the nail-shooting firing pin moves to the nail shooting position under the action of high pressure air in the compression air cylinder, and the transmission ratchet wheel is provided with a pawl which can control the transmission ratchet wheel to rotate one way. The gun can realize reciprocating motion of the nail-shooting firing pin by the linkage and the tripping of the eccentric cam and the pin shaft, so as to impact nails; and the transmission ratchet wheel is arranged so as to prevent blank shooting. By using the structure, the gun is few in parts, simple and compact in structure, safe and reliable, and lower in cost.

Description

Ail gun is beaten in the air defense of cam disengaging type

Technical field

The utility model relates to ail gun, and ail gun is beaten in especially a kind of cam disengaging type air defense.

Background technology

Ail gun is widely used in many fields such as indoor dress is drilled, furniture making; The power that it provides through compressed air or motor or explosive; Utilize transmission mechanism to drive the nailing striker and do straight reciprocating motion, impact nail, nail is injected base material through the nailing striker that moves reciprocatingly.At present, the above-mentioned transmission mechanism structure more complicated of ail gun not only comprises a plurality of drives, also shift fork need be set, connecting rod or the like, and empty beating often appears, there is potential safety hazard.

The utility model content

The purpose of the utility model is: provide a kind of cam disengaging type air defense to beat ail gun, simple and compact for structure, safe and reliable, production cost is lower.

For realizing above-mentioned purpose, the utility model can be taked following technical proposals:

Ail gun is beaten in a kind of cam disengaging type air defense of the utility model; Comprise casing; Be arranged at the nailing striker in the compression cylinder on body of a gun right side in the casing, be provided with the Drive ratchet that is driven by motor in said body of a gun left part, said Drive ratchet is in transmission connection through bearing pin and the eccentric cam that is arranged on its end face; Said eccentric cam is connected with an end of steel wire rope, and the other end of this steel wire rope is connected with the left end of said nailing striker; Through eccentric cam the said nailing striker of the winding of steel wire rope is displaced into left end from right-hand member nailing position and waits to send out the position; Go to preset position through bearing pin, bearing pin and eccentric cam are threaded off, and utilize the effect nailing striker of compression cylinder inner high voltage gas to move in right-hand member nailing position; Said Drive ratchet has the ratchet of its one-directional rotation of control.

As preferably, the preset position of said bearing pin is positioned at the farthest apart from the eccentric cam axle center.

As preferably, the pikestaff portion of beating ail gun in said cam disengaging type air defense is provided with the change-over switch that is used to control revolution.

The beneficial effect of the utility model is: owing to adopt technique scheme, Drive ratchet is in transmission connection through bearing pin and the eccentric cam that is arranged on its end face, and said Drive ratchet is in transmission connection through bearing pin and the eccentric cam that is arranged on its end face; Utilize the eccentric distance between Drive ratchet and the eccentric cam; When Drive ratchet whenever rotates a circle, can realize engagement and dropout (promptly realizing clutch conversion) between bearing pin and the eccentric cam, when under the driving of eccentric cam at bearing pin steel wire rope being twined; Said nailing striker is pulled to left end and waits to send out the position from right-hand member nailing position; When eccentric cam and bearing pin dropout, compression cylinder inner high voltage gas acts on the nailing striker, and the nailing striker is end motion left fast; Move to right-hand member nailing position to impact nail, nail is injected base material; In order to prevent empty beating, said Drive ratchet also is provided with the ratchet that is used to control its one-directional rotation.This structure, parts are few, and are simple and compact for structure, safe and reliable, and production cost is lower.
