Technical Field
The invention belongs to the technical field of nailing guns, and relates to a resetting control device of a nailing gun.
Background
A nailing gun is a common tool and generally includes a gun body, a firing pin, and a nail ejection slot. The working principle of the nailing gun is that a piston in the nailing gun is moved, the volume of a gas storage cavity is reduced, gas in the cavity is compressed, and large pressure is generated, so that a firing pin in the nailing gun is under large pressure, and the firing pin is in a locking state at the beginning. When the nail is nailed, the nail nozzle of the nail gun is abutted against the position needing nailing, and after the firing pin is unlocked, the firing pin impacts the nail in the nail box to drive the nail into the position needing nailing. In the using process, when the volume of the gas storage cavity is reduced and the piston moves for a certain distance but does not reach the preset position to stop moving, the gas pressure in the gas storage cavity cannot reach the preset nailing force, and the result of poor nailing effect is caused. If the control piston continues to move to the designated position when the piston stops moving, the piston can move to the designated position again but cannot stop due to a certain distance of movement of the piston in the process of one power accumulation, and finally the structure of the nailing gun is damaged.

When the nail-shooting force needs to be reduced, the rotary table 15c is rotated, the relative position of the threaded column 15a and the rotary table 15b is changed, so that the threaded column 15a moves towards the direction of the connecting strip 14, the distance between the threaded column 15a and the connecting strip 14 is shortened, namely the movable range of the connecting strip 14 towards the threaded column is reduced, the distance between the nail mouth 12a and the nail-shooting part cannot be further reduced, namely the distance between the nail mouth 12a and the nail-shooting part is larger, and the nail-shooting force is partially reduced.
The working principle of the scheme is that when the nailing gun is in a single nail shooting working mode, before nailing, the position of the connecting strip 14 is adjusted through rotation of the rotary disc 15c, the contact head 13c abuts against the wall, the trigger reed 17a deforms, the trigger switch 17 is opened, the nailing switch 11 is pressed, the circuit is communicated, the controller 6 reads an initial nail shooting state signal, the controller 6 reads the initial nail shooting state signal, namely the first sensor 6a detects that the first piston 4 is located at the first position, the controller 6 drives the motor 7 to push the first piston 4 to move towards the second position, when the first piston 4 moves towards the second position, the air pressure in the air storage cavity is larger than atmospheric pressure, the controller 6 enables the locking device 10 for locking the striker to be unlocked, the second piston 5 pushes the striker to shoot the nail under the pressure, after the nail shooting is completed, the controller 6 controls the motor 7 to drive the first piston 4 to move from the second position to the first position, and as the air pressure in the air storage cavity is smaller than the air pressure, the second piston 5 pushes the second piston 5 to return to the designated position again, the reset is realized, and the controller 6 controls the locking device 10 to lock the locking device again.
When the first piston 4 moves to the first position and the second position intermediate position for the first time and stops, because the controller 6 sets the same number of turns of the motor 7, the motion track of the first piston 4 changes to move from the first position and the second position intermediate position to the second position and the first position intermediate position and then to the first position and the second position intermediate position; the motion track of the first piston 4 is changed to move from the first position and the second position to the second position and the first position middle position, the first piston 4 is changed from the first position to the first position and the second position middle position in the initial position of the nail shooting process, the locking device 10 of the striker is unlocked when the first piston 4 moves to the second position, the nail shooting is realized, the first piston 4 continues to move to the middle of the second position and the first position, the pressure of the air storage cavity is smaller than the air pressure, the second piston 5 moves back for a certain distance, and the process is equivalent to the process that the first piston 4 moves from the first position to the second position in the normal nail shooting process; when the first piston 4 goes from the middle of the second position and the first position to the middle of the first position and the second position, the second piston 5 is not in the initial state due to the fact that the pressure in the air storage cavity is different from the pressure in the air storage cavity in normal work, the striker cannot be locked, and the follow-up nailing function cannot be achieved.
When the first piston 4 stops moving to the middle of the second position and the first position, namely the first piston stops in the return stroke process, and when the first piston 4 stops moving to the middle of the first position and the second position from the middle of the second position and the first position, the second piston 5 is not in the initial state, so that the striker cannot be locked, and the subsequent nailing function cannot be realized.
In the process of one-time nail shooting, as the initial position of the first piston 4 is not at the first position, the second piston 5 cannot be locked when subsequent nail shooting is carried out, the controller 6 reads the initial nail shooting state signal when the nail shooting is started, and the motor 7 is controlled to enable the crank-link mechanism 9 to drive the first piston 4 to be at the first position, so that the nail gun can restore to normal nail shooting, the safety of the nail gun is improved, and in the subsequent nail shooting process, when the nail shooting is started every time, the controller 6 reads the initial nail shooting signal and then completes one-time nail shooting.
As shown in fig. 6, when the nailing gun is in the continuous nailing mode, each time the nailing is started, the controller 6 reads the initial nailing signal and then completes one nail shooting, when the nailing gun is started later, the controller 6 reads the initial nailing signal at a predetermined nail shooting time, the predetermined nail shooting time is 0.2-0.5 second, and during the nail shooting process, the controller 6 alternately reads the detection signal of the first sensor 6a and the detection signal of the second sensor 6b, and when the detection signal of the first sensor 6a or the detection signal of the second sensor 6b is not read within the predetermined nail shooting time, the deviation of the movement of the first piston 4 can be determined, the controller 6 controls the motor 7 to rotate reversely to move the first piston 4 to the first position and read the initial nailing state signal until the controller 6 reads the initial nailing state signal again, the continuous nailing mode is restarted, which is beneficial to recovering the normal nail shooting of the nailing gun, the safety of the nailing gun is improved, and the controller 6 alternately reads the detection signals of the first sensor 6a and the second sensor 6b, and the detection signal of the second sensor 6 is 0.2-0.5 second.
Example two
As shown in fig. 7, the present embodiment is substantially the same as the first embodiment, except that a pressure sensor 17b is further disposed on the second embodiment, the controller 6 reads a value of the pressure sensor 17b, when the pressure sensor 17b is greater than a certain value, the controller 6 does not receive a signal of the trigger switch 17 any more until the controller 6 detects an initial nail shooting status signal, and the controller 6 receives a signal of the trigger switch 17 again. When the numerical value of the pressure sensor 17b is larger, the deformation amount of the spring 17a is triggered to be larger, at the moment, the nailing needs larger nail shooting force, the controller 6 receives an initial nail shooting state signal, namely, the first piston reaches the first position when the nailing is started, the nailing can be continued, and the nail shooting safety is improved.
