Handheld screw locking tool and screw feeding and locking machine with handheld screw locking tool

Abstract

The invention relates to a handheld screw locking tool and a screw feeding and locking machine with the handheld screw locking tool. The handheld screw locking tool comprises a tool shell, a hollow screwdriver, an air cylinder, a bit and a transmission shaft. The hollow screwdriver is arranged in the tool shell. The air cylinder comprises a piton rod capable of sliding in the air cylinder. The piston rod is connected with one end of the transmission shaft. The other end of the transmission shaft penetrates the hollow screwdriver to be connected with the bit. The hollow screwdriver is connected with the transmission shaft in a transmission manner. The invention further provides the screw feeding and locking machine with the handheld screw locking tool. The handheld screw locking tool and the screw feeding and locking machine have the beneficial effects that due to the structure of the screw locking tool, a screw and a screw hole can be easily aligned, and operation is easy and saves labor; when operation is carried out, compressed air serves as power, the bit is driven by the air cylinder to perform up-and-down movement, and when the bit ascends, the fed screw is received through a pipe; and when the bit performs downward pressing, the screw can be ejected or ejected out of a screw chuck and sucked on the bit, and convenience is brought to manual alignment.

Description

technical field [0001] The invention relates to the field of mechanical structures, in particular to a hand-held locking screw tool and a locking screw machine containing the tool. Background technique [0002] At present, there are two kinds of operations for tightening screws: manual tightening and automatic locking screw machine. Manual tightening includes pure manual tightening and electric screwdriver or pneumatic screwdriver tightening. The latter generates rotational power through electric or pneumatic means to replace frequent manual tightening actions, which reduces the work of locking screws to some extent. Strength, but because manually placing the screws and aligning the screw heads still takes a lot of work time and energy, the overall efficiency improvement is relatively limited. In order to improve the working efficiency of locking screws, the industry has developed an automatic locking screw machine. The automatic locking screw machine is also called automat...

[0005] 2. In order to reduce the labor intensity, the strength of the spring is relatively small. After the telescopic sleeve pops up after locking the screw, the next screw will be blown into the screw chuck. However, the elastic force of the spring is small or there is friction and other reasons. The cylinder may not pop out in place, causing the rod to block the conveying channel of the screw, causing the rod and the screw to be stuck in the chuck, resulting in failure

[0006] 3. Because the screw is hidden in the collet or the protruding collet is short, it is difficult to align the hand-held tool with the screw hole. If it is not aligned once, the screw will retract into the screw collet, making alignment more difficult
