Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to a nail driver. Background Art

[0002] The nail driver accumulates force by compressing the spring, and resets the spring through elastic deformation to push the firing member to hit the nail to complete the nailing action. However, the firing force required for nailing is different depending on the working scenario. If the firing force of the machine is too strong, the nail will be embedded too deeply into the object being nailed, which may damage the surface or internal structure of the object; or, if the firing force of the machine is insufficient, the nail cannot be fully driven in, affecting the firmness of the connection.

[0044] The nail driver accumulates force by compressing the spring, and resets the spring through elastic deformation to push the firing member to hit the nail to complete the nailing action. However, the firing force required for nailing is different depending on the working scenario. If the firing force of the machine is too strong, the nail will be embedded too deeply into the object being nailed, which may damage the surface or internal structure of the object; or, if the firing force of the machine is insufficient, the nail cannot be fully driven in, affecting the firmness of the connection.

[0045] Therefore, existing nail drivers are often equipped with a mechanism for manually adjusting the firing force, and the firing force of the nail driver is adjusted by manually rotating an adjustment knob to adjust the spring compression length. However, this manual adjustment process is laborious and inefficient.

[0046] In order to solve the above problems, the present application proposes a nailing device. Figure 1 to Figure 2 As shown, the nail driver includes a firing mechanism 100 and an adjusting mechanism 200. The firing mechanism 100 is used to fire the nail, and the adjusting mechanism 200 is used to adjust the firing force of the nail, thereby adjusting the depth of the nail embedded in the nailed object.

[0047] Specifically, the firing mechanism 100 includes a first driving member 110, an elastic member 120 and a firing member 130. The firing member 130 is connected to the elastic member 120 so that when the firing member 130 moves along the extension direction of the elastic member 120, the elastic member 120 can be driven to undergo elastic deformation. The firing member 130 is transmission-connected to the first driving member 110, that is, the firing member 130 can be directly connected to the first driving member 110, or can be indirectly connected to the first driving member 110 through a transmission structure, and the first driving member 110 can drive the firing member 130 to move when it is working. The first driving member 110 can be a motor, an electric cylinder, a pneumatic cylinder, etc.

[0048] Driven by the first driving member 110, the firing member 130 has an initial position and a moving position. When the first driving member 110 drives the firing member 130 to move from the initial position to the firing position, the elastic member 120 is gradually compressed and deformed, thereby accumulating elastic potential energy. After the firing condition is met, the firing member 130 moves from the firing position to the initial position to release the elastic potential energy and restore the elastic deformation. The firing member 130 is driven to move and hit the nail on the moving path, thereby completing the firing of the nail. Figure 3 As shown, the firing member 130 is connected to a firing pin 133 . Under the elastic action of the elastic member 120 , the firing member 130 drives the firing pin 133 to move so as to strike the nail.

[0049] The adjustment mechanism 200 includes a second driving member 210 and a first connecting member 220. The first connecting member 220 is connected to the second driving member 210 in a transmission manner. That is, the first connecting member 220 can be directly connected to the second driving member 210, or can be indirectly connected to the second driving member 210 through a transmission structure. When the second driving member 210 is working, it is sufficient to drive the first connecting member 220 to move. In the initial state, the first connecting member 220 and the elastic member 120 can be in a connected relationship or a non-connected relationship. If they are in a non-connected relationship, when the second driving member 210 is working, the first connecting member 220 is driven to move and abut against the elastic member 120, thereby pushing the elastic member 120 to deform.

[0050] When the second driving member 210 is working, the first connecting member 220 is driven to move along the expansion and contraction direction of the elastic member 120, that is, the first connecting member 220 moves closer to or away from the firing member 130, thereby changing the compression degree of the elastic member 120 between the first connecting member 220 and the firing member 130. The second driving member 210 can be a motor, an electric cylinder, a pneumatic cylinder, etc.

[0051] The adjustment mechanism 200 can adjust the compression degree of the elastic member 120 when the firing member 130 is in the initial position or the firing position. The adjustment mechanism 200 can also be adjusted at any time when the firing member 130 moves from the initial position to the firing position, or from the firing position to the initial position.

[0052] Take the firing member 130 at the initial position as an example. At this time, the elastic member 120 is in a compressed state or a free state. If the operator feels that the nail shooting depth is not enough at this time, the second driving member 210 can be controlled to work to drive the first connecting member 220 to move toward the firing member 130, so that the initial compression degree of the elastic member 120 between the first connecting member 220 and the firing member 130 is greater. Furthermore, when the firing member 130 moves from the initial position to the firing position, compared with the compression degree of the elastic member 120 before adjustment, the compression degree of the elastic member 120 after adjustment is greater, so that the elastic potential energy accumulated by the elastic member 120 is greater, and the kinetic energy given to the nail when released is greater, and the depth of the nail shot into the nailed object can be deeper.

[0053] Alternatively, if the elastic member 120 is in a compressed state when the firing member 130 is in the initial position, and the operator feels that the nailing depth is too deep, the second driving member 210 can be controlled to work, and the first connecting member 220 can be adjusted to move away from the firing member 130, so that the initial compression degree of the elastic member 120 between the first connecting member 220 and the firing member 130 becomes smaller, so that when the firing member 130 moves to the firing position, the compression degree of the elastic member 120 is smaller, thereby reducing the firing force of the nail.

[0054] Based on the above, the present application realizes the electric firing of nails and the electric adjustment of the firing force by setting up a firing mechanism 100 and an adjustment mechanism 200. There is no need for manual adjustment to change the firing force of the nails, which greatly facilitates the operator to make adjustments according to the conditions of the construction site. The adjustment process saves time and effort and is highly efficient.

[0055] In some embodiments, Figures 2 to 4 As shown, the first connecting member 220 and the firing member 130 are respectively connected to the two ends of the elastic member 120 along the extension direction, so that the adjustment mechanism 200 can adjust the compression degree of the entire elastic member 120 and make full use of the elastic deformation of the entire elastic member 120.

[0056] In some embodiments (not shown in the figure), the second driving member 210 includes a retractable output shaft, the retracting direction of the output shaft is parallel to or coincides with the retracting direction of the elastic member 120, and the output shaft is connected to the first connecting member 220 to drive the first connecting member 220 to move along the retracting direction of the elastic member 120, thereby compressing or extending the elastic member 120. It should be noted that the "compression or extension" mentioned here is compared with the length of the elastic member 120 before adjustment, rather than the length of the elastic member 120 in a free state.

[0057] In other embodiments, the first connecting member 220 plays a transmission role. For example, the adjustment mechanism 200 further includes a second connecting member 230, which is connected to the second driving member 210, and the second connecting member 230 is also connected to the first connecting member 220, so that the second driving member 210 drives the elastic member 120 to deform through the second connecting member 230 and the first connecting member 220 in sequence.

[0058] The second driving member 210 includes a rotatable second output shaft 212, and the first connecting member 220 and the second connecting member 230 can convert the rotation of the second output shaft 212 into a linear drive of the first connecting member 220, thereby driving the elastic member 120 to deform. For example, the first connecting member 220 is a screw rod, and the second connecting member 230 is a slide seat, the slide seat is provided with a through hole, the screw rod is passed through the through hole, and the hole wall of the through hole is threadedly connected with the slide seat, so that the slide seat is driven to rotate through the second driving member 210 to move the screw rod, thereby driving the elastic member 120 to deform.

[0059] Specifically, Figure 4 As shown, an opening is provided at one end of the screw along its axial direction, and a cavity is defined inside the screw. One end of the elastic member 120 is inserted into the cavity through the opening and abuts against the cavity wall at the other end. The cavity wall of the screw can guide the elastic member 120 to move, so as to prevent the elastic member 120 from bending under force. The nail driver has a housing 300, and a bearing 222 is connected to each of the two ends of the slide along its axial direction. A limiting structure is provided on the housing 300. The limiting structure can be a rib formed by integral injection molding with the housing 300, which can abut against the end face of the bearing 222 along its axial direction, or a structure connected to the housing 300 for limiting the movement of the bearing 222. The bearing 222 is connected to the limiting structure, so that the slide is limited to the housing 300, and the slide can only rotate, and cannot move along the telescopic direction of the elastic member 120. Therefore, when the slide is driven to rotate, the screw moves along the telescopic direction of the elastic member 120.

[0060] Further, such as Figure 3 As shown, the output shaft of the second driving member 210 is sleeved with a first tooth portion 211, and the outer peripheral surface of the slide is provided with a second tooth portion 231, and the first tooth portion 211 and the second tooth portion 231 are meshed and driven to drive the slide to rotate. Through this transmission structure, the second driving member 210 is arranged in parallel with the elastic member 120, and the length direction of the second driving member 210 is parallel to the length direction of the elastic member 120, so that the overall structure is relatively compact.

[0061] Alternatively, the first connecting member 220 and the second connecting member 230 can also be a gear rack structure (not shown in the figure). For example, the first connecting member 220 is connected to the elastic member 120, and a rack extending along the expansion and contraction direction of the elastic member 120 is provided on the outer wall of the first connecting member 220. The second driving member 210 can be arranged parallel to the expansion and contraction direction of the elastic member 120, and a first tooth portion 211 is sleeved on its output shaft. The second connecting member 230 is a bevel gear to change the transmission direction. The first tooth portion 211, the bevel gear, and the rack are meshed in sequence, so that the first connecting member 220 is driven by the rotation of the first tooth portion 211 to cause the elastic member 120 to deform.

[0062] It is understandable that the transmission structure from the second driving member 210 to the first connecting member 220 may also be in other forms, which are not listed here one by one.

[0063] In some embodiments, the nail driver further includes a first detector 240 and a trigger 221, and signals can be transmitted between the trigger 221 and the first detector 240, or the first detector 240 can receive a specific signal from the trigger 221. For example, the first detector 240 can be a Hall element, and the trigger 221 can be a magnet, and the Hall element can receive the magnetic field signal of the magnet to obtain the position of the magnet. The first detector 240 can also be a photoelectric sensor, an infrared sensor, etc.

[0064] In such Figure 4 In the illustrated embodiment, the trigger member 221 is connected to the first connecting member 220, and the trigger member 221 moves with the movement of the first connecting member 220. The first detecting member 240 is fixed around the moving path of the first connecting member 220. For example, the first detecting member 240 can be arranged on the housing 300 of the nail driver, or on the outer peripheral wall of the second driving member 210. It should be noted that since the first detecting member 240 needs to be connected to a communication cable, the first detecting member 240 is fixedly arranged in the housing 300 to avoid signal failure caused by pulling the communication cable.

[0065] Thus, when the adjustment mechanism 200 adjusts the compression degree of the elastic member 120, the trigger member 221 moves with the first connecting member 220. The first detecting member 240 obtains the position of the trigger member 221 before and during the adjustment, and then transmits it to the controller of the nail driver for data processing to obtain the movement amount of the first connecting member 220, and then obtains the real-time compression amount of the elastic member 120, so that when the elastic member 120 is adjusted to the target position, a signal is sent to the controller, and the second driving member 210 is controlled to stop working.

[0066] It is understandable that in other embodiments, the first detection member 240 is connected to the first connecting member 220 and moves with the first connecting member 220 relative to the trigger member 221. The trigger member 221 is fixedly disposed in the shell 300, and the first detection member 240 can obtain the position of the trigger member 221.

[0067] In some embodiments, Figure 1 and Figure 2 As shown, the nail driver includes a housing 300 and a power source 311. The housing 300 defines a gripping portion 310, a working portion 320 and a driving portion 330. The working portion 320 is located at the same end of the gripping portion 310 and the driving portion 330. The gripping portion 310, the working portion 320 and the driving portion 330 enclose and define a gripping space 340, so that the operator can hold it with one hand. A control switch 312 is provided on one side of the gripping portion 310 close to the gripping space 340, which can be used to control the operation and stop of the first driving member 110.

[0068] The elastic member 120 and the second driving member 210 are arranged in parallel in the working part 320, and the extension direction of the elastic member 120 is arranged parallel to the length direction of the second driving member 210. Figure 4 In the embodiment shown, the length of the elastic member 120 in the free state is longer than the length of the second driving member 210. Figure 4 In the left-right projection, the second driving member 210 is located between the two ends of the elastic member 120, so that the layout inside the working portion 320 is more compact.

[0069] The power supply 311 is disposed in the gripping portion 310, and the first driving member 110 is disposed in the driving portion 330. Since the heavier first driving member 110 and the power supply 311 are respectively located on both sides of the gripping space 340, the center of gravity of the entire nail driver is reasonably configured, the center of gravity of the nail driver is stable when in use, and the user experience is good.

[0070] In some further embodiments, in order to facilitate the operator to adjust the compression degree of the elastic member 120, the nail driver is further provided with a display 322, and the housing 300 is defined with a nail outlet 321 for ejecting nails. Figure 1 and Figure 2 The nail outlet 321 is located at one end of the working part 320 close to the driving part 330, and the display 322 is located at one end of the working part 320 close to the holding part 310. Therefore, when the operator holds the nail driver to operate, the operator can observe the information displayed on the display 322, and the design position of the display 322 is more humane.

[0071] The display 322 is at least connected to the second driving member 210 in communication, so that the second driving member 210 can be controlled to rotate forward or reverse by clicking the area on the display 322 representing the increase or decrease of the firing force. It is understandable that the display 322 can also be connected to the controller in communication, and the controller is respectively connected to the first driving member 110, the first detection member 240 and other components, so that the current firing force gear, the working parameters of the first driving member 110, etc. can also be displayed on the display 322.

[0072] In some further embodiments, the nail driver can also be provided with a button, a knob, etc. to communicate with the controller, so as to achieve the purpose of adjusting the firing force. For example, by providing a knob to communicate with the controller, the forward rotation of the knob represents an increase in the firing force, and the reverse rotation of the knob represents a decrease in the firing force. The second driving member 210 performs a corresponding action after receiving the controller instruction.

[0073] In some embodiments, the nail driver further includes a safety member 400 and a second detection member 410 to prevent the operator from accidentally triggering the nail driver. Figure 2 and Figure 3 As shown, one end of the safety member 400 is inserted into the nail outlet 321 and exposed outside the housing 300. When using the nail driver, the nail outlet 321 needs to be pressed against the nailed object first, so that the safety member 400 is subjected to the resisting force and moves toward the inside of the housing 300. The second detection member 410 is arranged on the moving path of the safety member 400. When the safety member 400 can move toward the second detection member 410, the second detection member 410 is triggered. The second detection member 410 can be a proximity switch, a photoelectric sensor, etc. When the safety member 400 moves into the detection range of the second detection member 410, the second detection member 410 is triggered. Alternatively, the second detection member 410 can also be a push switch, a pressure sensor, etc. When the safety member 400 moves to abut against the second detection member 410, the second detection member 410 is triggered.

[0074] The second detection member 410 is connected to the controller for communication. When the second detection member 410 is triggered, the control circuit of the nail driver is connected, so that the operator can press the control switch 312 to perform the nailing operation. When the nail driver is removed from the nailed object, the safety member 400 is driven to reset by the spring, and the second detection member 410 is not triggered, so that the control circuit of the nail driver is disconnected and the nail driver cannot perform the nailing operation, so as to avoid the operator accidentally touching the switch to drive the nail and cause a safety accident.

[0075] In some embodiments, Figure 3 , Figure 5 and Figure 6As shown in FIG. 1 , the first driving member 110 includes a rotatable first output shaft, and the rotating member 111 is connected to the first output shaft, so that the rotating member 111 can rotate synchronously with the first output shaft. The rotating member 111 is provided with a first protrusion 112, and the first protrusion 112 is arranged deviated from the rotation center of the rotating member 111, that is, the first protrusion 112 is eccentrically arranged. It can be understood that since the first protrusion 112 is eccentrically arranged, during the rotation of the first protrusion 112 with the rotating member 111, the first protrusion 112 will also rotate along the same direction as shown in FIG. Figure 5 and Figure 6 As shown in the upward and downward movement, the first protrusion 112 abuts against the firing member 130 during the movement of the first protrusion 112 from bottom to top, and drives the firing member 130 to move from the initial position to the firing position. It should be noted that Figure 5 FIG. 1 is a schematic diagram showing the firing member 130 in an initial position. Figure 6 Shown is a schematic diagram of the firing member 130 in the firing position.

[0076] Further, such as Figure 5 and Figure 6 As shown, the firing member 130 includes an abutment portion 131 and an avoidance groove 132. When the firing member 130 moves from the initial position to the firing position, the first protrusion 112 abuts against the abutment portion 131 and moves toward the avoidance groove 132. When the first protrusion 112 is separated from the abutment portion 131 and enters the avoidance groove 132, the abutment driving effect of the first protrusion 112 on the firing member 130 is eliminated, so that the firing member 130 is driven by the elastic restoration of the elastic member 120 to move downward rapidly, so as to hit the nail to eject it.

[0077] Furthermore, the nail driver further comprises a third detection member 140, Figure 3 , Figure 5 and Figure 6 As shown, when the first protrusion 112 drives the firing member 130 to move to the firing position, the firing member 130 triggers the third detection member 140. The third detection member 140 can be a proximity switch, a photoelectric sensor, etc., and when the firing member 130 moves into the detection range of the third detection member 140, the third detection member 140 is triggered. Alternatively, the third detection member 140 can also be a press switch, a pressure sensor, etc., and when the firing member 130 moves to abut against the third detection member 140, the third detection member 140 is triggered.

[0078] In response to the third detection member 140 being triggered, the controller determines that the firing member 130 has completed one lift, and controls the first driving member 110 to stop rotating, thereby controlling the first output shaft of the first driving member 110 to rotate less than 360 degrees each time when driving the firing member 130, so as to avoid continuous nailing at the same position. When the operator needs to nail again, he needs to release the control switch 312 and press the control switch 312 again.

[0079] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
