The utility model relates to an automatic excitation device of a pneumatic nail gun, which comprises a gun body, a piston assembly of a nail impact needle corresponding to each other and a swimming valve assembly. The main pipe arranged on the gun body is connected with the piston assembly of a nail impact needle. The utility model is characterized in that an air control switch is arranged on the gun body, and the air control switch is connected with a swimming valve chamber through a guide pipe. The connecting position is located at the back of the swimming valve, and the air-controlled switch and the main pipe supply gas to each other independently. The structure of the utility model realizes the fast pneumatic nail gun internal pressure difference conversion by using independent air supply and directly drives the swimming valve by high-pressure gas of the pneumatic switch, which can directly and reliably realize piston reversal. It not only effectively and reliably realizes the pneumatic nail gun's shooting and retreating, but also overcomes the technical difficulties of slow shooting and retreating in the existing technology, and makes the structure even more reliable. It is suitable for the occasion of automatic pneumatic nail gun shooting.

一种气动钉枪自动激发装置
本技术涉及一种气动钉枪零部件,尤其涉及一种气动钉枪自动激发装置。
技术介绍
气动钉枪也叫气动打钉机,气钉枪以气泵(空气压缩机)产生的气压,小枪气压〔4-6.5Kg/c㎡(Bar)〕大钉枪气压〔5-8Kg/c㎡(Bar)〕体为动力源,高压气体带动钉枪气缸里的撞针做锤击运动,将排钉夹中的排钉钉入物体中或者将排钉射出去。而应用在这种气动钉枪上的钉子则统称气动枪钉。在自动化生产的场景中,部分生产工序需要进行自动化的气动打钉加工操作,因此气动钉枪需要实现自动激发功能来满足自动化生产需要。在现有的气动钉枪中,通常是采用同一个供气气源,通过手动阀门控制游动阀与活塞气筒腔之间的压力差,而实现气动钉枪的激发与回退,这种结构的缺点在于其应用于自动化打钉操作时,钉枪的安装方式别扭,同时由于其气压差的转换速度缺陷,很难实现精准的高速连续激发,导致在自动化打钉操作时容易出现控制误差。有部分钉枪通过复位弹簧或者其他的形式实现自动激发复位,然而其结构十分复杂,装配要求高同时其工作灵敏度不足,气动钉枪的反应速度缓慢,使产品在流水线打钉生产的操作中经常出现漏打、错打的技术 ...
