Problems solved by technology

First of all, driving a nail with a hammer requires a lot of force to drive the nail in, and the labor intensity is high.
Secondly, nailing with a nail hammer requires fingers to hold the middle of the nail. During the hitting process, once there is a deviation, it is easy to hit the finger, causing injury accidents, and its safety is low.
Finally, even for professional carpenters, if a large number of nails need to be nailed every day, even skilled workers can hardly nail more than 20 nails per minute by hand under the premise of ensuring accuracy. nails, work efficiency is also low
Therefore, in the prior art, also there is not a kind of power tool that can realize the process of finishing nails in an automatic manner.

Abstract

The invention discloses a pneumatic hammer comprising an air supplying device, a cylinder, a piston, a reversing valve, a piston resetting device and a striking device, wherein the piston for separating a first chamber and a second chamber is arranged in the cylinder; a piston rod hermetically penetrates through the second chamber and is connected with the striking device; an exhaust port C3 is arranged on the cylinder; a movable valve core of the reversing valve moves under the drive of pressure difference generated by alternate changes of pressure in the first chamber or the second chamber so as to alternately connect or disconnect the communication between the first chamber or the second chamber of the cylinder and compressed air; air inlet and exhaust of the first chamber and the second chamber of the cylinder are switched by the match of the reversing valve and the reciprocating motion of the piston so that the piston can be automatically reversed; and the purpose of striking round nails can be achieved by driving the piston to reciprocate and drive the striking device connected with the piston rod to reciprocate under the reciprocating motion of the piston in the cylinder. The invention provides a high-efficient and professional pneumatic hammer capable of automatically striking the round nails.

Description

technical field [0001] The invention relates to an automatic nail driving device, in particular to a round nail automatic driving installation tool for carpentry. Background technique [0002] At present, nail hammers on the market rely on manual hammering to complete the nailing process. During the operation, the operator swings the nail hammer to hit the bottom of the nail, so that the nail is embedded in the object to be fixed. This method is used There are limitations. First of all, it takes a lot of force to nail the nails through a hammer, and the labor intensity is high. Secondly, nails need to be held by fingers to hold the middle of the nail by hammering. During the hitting process, once there is a deviation, it is easy to hit the fingers, causing injury accidents, and its safety is low. Finally, even for professional carpenters, if a large number of nails need to be nailed every day, even skilled workers, under the premise of ensuring accuracy, it is difficult to...
