In many engineering construction, building construction, interior and exterior finishing, furniture manufacturing, exhibition arrangement, etc., it is necessary to fix components to be fixed to a substrate by using a nail gun. Currently, the most widely used is the pneumatic nailer which uses compressed air as a power source. However, the air pump, which is a power source of the pneumatic nailing gun, is a relatively heavy device and is inconvenient to move and carry. Thus, electric power nailers have been developed. The electric nailing gun on the market mainly uses commercial power as a power supply and is driven by an electromagnetic coil. The electromagnetic coil driven nail gun not only needs to drag one electric wire, so that the use is inconvenient; moreover, the driving force of the electromagnetic coil is obviously insufficient, and the actual engineering requirements cannot be met. Has been gradually replaced by battery-powered so-called cordless nailers in the trend.
The cordless nail gun mainly works in a mode that an energy storage mechanism is driven by a motor, and the nailing is quickly released after energy storage. A typical cordless nailer requires an energy storage process after receiving a stapling command and then releases energy to perform the stapling command. Thus, an energy storage delay exists from the time of receiving a nailing command from the cordless nail gun to the time of nailing, and the overall nailing speed of the nail gun is reduced, so that the working efficiency of the nail gun is reduced.

As shown in fig. 2 and 3, in another embodiment, the driving nailing mechanism 400 includes a hydraulic driving part 410 and a nailing part 420 for nailing, and the communication chamber 110 is opened in the support structure 100 as a communication passage of the hydraulic driving part 410.
As shown in fig. 3 and 5, as an alternative embodiment, the eccentric member 320 includes an eccentric shaft 321 and a bearing sleeved on the eccentric shaft 321. The eccentric shaft 321 is in transmission connection with the power component 310, the bearing is abutted with the linear motion component 330, the power component 310 drives the eccentric shaft 321 to drive the bearing to rotate, and the bearing drives the linear motion component 330 to do linear motion. Preferably, the bearings are rolling bearings to reduce friction loss of motion transmission, so that the linear motion component 330 does linear motion without lateral friction force, and high energy storage efficiency is ensured. During energy storage, the eccentric motion of the eccentric shaft 321 can drive the bearing to eccentrically rotate, drive the linear motion component 330 to linearly move, and drive the compression energy storage mechanism 200 to store energy; when the energy storage mechanism 200 releases energy, the linear motion member 330 is pushed to perform linear motion, and the nail is impacted by driving the nailing mechanism 400.

The rotating shaft is in transmission connection with the power component 310, the eccentric bearing is abutted with the linear motion component 330, the power component 310 drives the rotating shaft to drive the eccentric bearing to rotate, and the eccentric bearing drives the linear motion component 330 to do linear motion.

In one embodiment, as shown in fig. 3 and 6, the unidirectional locking structure 340 is disposed between the supporting structure 100 and the eccentric member 320, and optionally, the unidirectional locking structure 340 may be a ratchet-pawl structure, or may be other structures capable of achieving a unidirectional locking function, further, the unidirectional locking structure 340 includes a unidirectional bearing, one end or two ends of the eccentric member 320 are rotatably disposed on the supporting structure 100 through the unidirectional bearing, and the unidirectional bearing has the advantages of simple structure, strong interchangeability, stable performance, and easy disassembly.
Alternatively, the position sensor may be various photoelectric sensors, angular displacement sensors, proximity switches, etc. capable of detecting positional information of the eccentric shaft, or other sensors capable of detecting rotational positions of the eccentric member 320. The position sensor is electrically connected with the driving motor 311, and when the eccentric member 320 is driven to approach the top dead center position, the position sensor sends out a signal to control the driving motor 311 to stop working. In a specific embodiment, the position sensor is a photoelectric angular displacement sensor, which sends out a signal to stop the rotation of the drive motor 311 when the eccentric shaft 321 rotates to a top dead center position near the maximum energy storage state. When a nailing command is received, the driving motor 311 drives the eccentric shaft 321 to pass through the top dead center position, after nailing is finished, nailing equipment automatically enters the next energy storage process, the driving motor 311 drives the eccentric shaft 321 to rotate for energy storage, when the position sensor detects that the eccentric part 320 is 0-20 degrees before the top dead center position, the driving motor 311 stops working, the one-way locking structure 340 carries out reverse locking on the eccentric part 320, so that the eccentric part 320 can not rotate reversely under the driving of the energy storage mechanism 200, and can not pass through the top dead center position to miss nailing, and the nailing equipment is in a nailing preparation state. When the nailing device receives the next nailing command, the eccentric part 320 can realize nailing action only by being driven by 0-20 degrees, so that the nailing waiting time is greatly shortened, and the nailing efficiency is ensured. Further, when the position sensor detects that the eccentric member 320 is 5 ° -10 ° before the top dead center position, the driving motor 311 stops working, and the one-way locking structure 340 locks the eccentric member 320 in the reverse direction, so that the eccentric member 320 is neither reversed under the driving of the energy storage mechanism 200 nor erroneously nailed beyond the top dead center position, and the nailing apparatus is in a ready-to-nailed state. When the nailing device receives the next nailing command signal, the eccentric part 320 can realize nailing action only by being driven by 5-10 degrees, so that the nailing waiting time is greatly shortened, and the nailing efficiency is ensured.
As shown in fig. 6 and 7, in one embodiment, the stored energy driving mechanism 300 further includes a one-way clutch member 350, the one-way clutch member 350 being mounted between the output shaft of the power member 310 and the eccentric member 320. As shown in fig. 8 and 11, when the energy storage mechanism 200 stores energy, the one-way clutch member 350 is in the connected position, the power member 310 drives the eccentric member 320 to rotate through the one-way clutch member 350, and the eccentric member 320 drives the linear movement member 330 to perform linear movement, so as to drive the energy storage mechanism 200 to store energy. When the energy storage mechanism 200 releases energy, as shown in fig. 9 and 10, the one-way clutch member 350 is in the disengaged position, the energy storage mechanism 200 drives the linear movement member 330 to perform linear movement, and the nail is driven into the substrate by driving the nailing mechanism 400. The one-way clutch member 350 is provided to allow the energy storage mechanism 200 to rapidly release energy during nailing, thereby improving the moving speed of the mechanism during nailing and ensuring the nailing effect.
The one-way clutch member 350 is always in the engaged position when the power member 310 drives the eccentric shaft 321 to rotate for energy storage. When the eccentric shaft 321 is driven by the energy storage mechanism and the rotational speed exceeds the rotational speed of the output shaft of the power component 310, the one-way clutch component 350 is always in the disengaged position. When the one-way clutch part 350 drives the eccentric shaft 321 to rotate, the eccentric shaft 321 drives the linear motion part 330 to enable the energy storage mechanism 200 to store energy, at the moment, the one-way clutch part 350 is at a connecting position, the driving motor 311 is in transmission connection with the eccentric shaft 321 through the one-way clutch part 350, and at the moment, the power of the driving motor 311 is transmitted to the eccentric shaft 321 through the one-way clutch part 350 to drive the eccentric shaft 321 to move. When the energy storage mechanism 200 releases energy, as shown in fig. 9 and 10, the energy storage mechanism drives the linear motion component 330 to move, the linear motion component 330 pushes the eccentric shaft 321 to rotate, the rotating speed of the eccentric shaft 321 exceeds the rotating speed of the output shaft of the power component 310, and the one-way clutch component 350 is in the separation position. Thus, the eccentric shaft 321 can freely and quickly rotate under the drive of the linear motion component 330, and only little energy is consumed, so that most of the energy accumulated on the energy storage mechanism 200 quickly impacts nails through the driving nailing mechanism 400 to drive the nails into the base material. As shown in fig. 11, when the energy storage mechanism 200 is completely released, the one-way clutch 350 is brought back into contact and the next energy storage process is performed.
The nailing device realizes unidirectional transmission of the power of the driving motor 311 through the unidirectional clutch component 350, ensures that the driving force of the driving motor 311 can drive the eccentric shaft 321 to drive the linear motion component 330 to store energy to the energy storage mechanism 200, and simultaneously ensures that the energy on the energy storage mechanism 200 is quickly released during nailing, and ensures the nailing effect. As one way of realisation, as shown in fig. 5 to 7, the one-way clutch part 350 includes a driving pin 351, a connecting shaft 352 and a driving disc 353, which are mounted on the eccentric part 320. The drive plate 353 is in driving connection with the output shaft of the speed reducer 312, the connecting shaft 352 is in rotational connection with the drive plate 353 with a rotational angle clearance of more than 90 °, and the drive pin 351 is in rotational connection with the connecting shaft 352 with a rotational angle clearance of more than 90 °. When the energy storage mechanism 200 stores energy, the driving disk 353 is in driving contact with the connecting shaft 352, and the connecting shaft 352 and the driving pin 351. The power part 310 contacts and drives the eccentric part 320 to rotate through the driving disc 353, the connecting shaft 352 and the driving pin 351, and the eccentric part 320 drives the linear motion part 330 to move so as to drive the energy storage mechanism 200 to store energy. When the energy storage mechanism 200 releases energy, the rotation speed of the driving pin 351 is larger than that of the connecting shaft 352, the driving pin 351 is separated from the connecting shaft 352, the connecting shaft 352 is separated from the driving disc 353, and the energy storage mechanism 200 drives the driving nailing mechanism 400 to strike nails so as to drive the nails into the base material.
Further, the number of the driving pins 351 is two, and the two driving pins 351 are provided on the end face of the eccentric shaft 321 near one end of the speed reducer 312, and the line connecting the two driving pins 351 passes through the rotation center of the eccentric shaft 321. The two sides of the connecting shaft 352 are respectively provided with a transmission shifting block 3521, and the two transmission shifting blocks 3521 are relatively fixed along the rotation direction of the eccentric shaft 321. The center of the driving disc 353 has a transmission through hole, two transmission protrusions 3531 are provided on the side wall of the transmission through hole, and a connection line of the two transmission protrusions 3531 passes through the rotation center of the driving disc 353. When the energy storage mechanism 200 stores energy, the output end of the speed reducer 312 drives the driving disc 353 to rotate, and the two transmission protrusions 3531 of the driving disc 353 are contacted with the transmission shifting block 3521 on one side of the connecting shaft 352, so that the driving disc 353 drives the connecting shaft 352 to rotate. The transmission dial 3521 on the other side of the connection shaft 352 is in contact with the two driving pins 351, and the connection shaft 352 drives the eccentric shaft 321 to rotate. The eccentric shaft 321 drives the linear motion component 330 to move, and then drives the energy storage mechanism 200 to store energy. When the energy storage mechanism 200 releases energy, the linear motion member 330 drives the eccentric shaft 321 to rotate rapidly. The rotation speed of the driving pin 351 is greater than that of the connection shaft 352, and the driving pin 351 is separated from the connection shaft 352. When the driving pin 351 reversely contacts with the transmission dial 3521 at one side of the connection shaft 352 and drives the connection shaft 352 to rotate, the rotation speed of the connection shaft 352 is greater than that of the driving disk 353. The driving dial 3521 at the other side of the connection shaft 352 is separated from the driving protrusion 3531 of the driving disk 353. During the energy release process of the energy storage mechanism 200, only the eccentric component 320 is driven to rotate, so that most of the energy stored on the energy storage mechanism 200 can quickly impact the nails through the driving nailing mechanism 400 to drive the nails into the base material. In other embodiments, the one-way clutch component 350 may also be a sprag-type one-way clutch, a roller-type one-way clutch, a ratchet-type one-way clutch, or other types of one-way clutches.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be regarded as the description scope of the present specification.
