Abstract

A pneumatic screw driving machine comprises an air chamber for reserving a compressed air, a main valve supplying the compressed air reserved in the air chamber to a hammering cylinder, a driver bit for driving and tightening a screw, a valve housing provided in the main valve, and a valve body so provided as to be capable of vertically movable with respect to the valve housing. A through hole opening to the air chamber is formed in the valve housing; and a lower opening part opening to the hammering cylinder, a side opening part opening to the air chamber through the through hole, and a first air supply passage allowing the lower opening part to communicate with the side opening part are formed in the valve body. When the valve body is moved downward, a second air supply passage allowing the air chamber to communicate with the hammering cylinder through the through hole is formed between the outer peripheral surface of the valve body on the lower side of the side opening part and the inner peripheral surface of the valve housing.

Description

technical field

[0001] The invention relates to an air pressure screw driver. Background technique

[0002] In general, an air pressure screwdriver lightly drives a driving screw into a driven part and then firmly tightens it. Corresponding to the process of driving and tightening the screws, the air pressure screw driver is provided with a striking mechanism for striking the driven screws and a screw tightening mechanism for rotating the driven screws. The percussion mechanism is integrated with a screwdriver head on the percussion piston that is slidably accommodated in the percussion cylinder, and the main valve is activated through the operation of the trigger, so that the air chamber storing compressed air is opened and closed relative to the above percussion cylinder, and the impact is directed to the percussion cylinder. The cylinder supplies compressed air to drive the percussion piston. When driving in, the front end of the driving screw needs to penetrate the sur...
