Description

Technical Field

[0001] This application relates to the field of nail gun technology, and more particularly to an electric nail gun. Background Technology

[0002] The linkage device of an electric nail gun mainly includes a motor, a linkage mechanism, and a push rod. The motor's output is connected to the linkage mechanism, and the push rod is also connected to the linkage mechanism. The motor drives the linkage mechanism to move, causing the push rod to reciprocate in a set direction to clamp the nail. However, in practical applications, during the process of driving the push rod through the linkage mechanism, in addition to the force acting in the direction of the push rod's movement, there are also forces acting in the up, down, left, and right directions. This can cause the push rod to rotate or swing during use, affecting the stable clamping of the nail. Utility Model Content

[0034] This utility model discloses an electric nail gun, comprising a base, a motor, a push rod, a linkage mechanism, and a limiting component. The motor drives the input end of the linkage mechanism to rotate, which in turn moves the output end of the linkage mechanism along a first direction.

Detailed Implementation

[0053] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0054] See also Figures 1-12 This invention illustrates a preferred embodiment of an electric nail gun, comprising:

[0055] The substrate 1 has a guide groove 14 extending along a first direction;

[0056] Motor 2, motor 2 is mounted on base 1;

[0057] Push rod 3 is movably disposed on base 1 along a first direction, and push rod 3 has positioning groove 31;

[0058] Linkage mechanism 4, the input end of linkage mechanism 4 is connected to the output end of motor 2, and the input end of linkage mechanism 4 can rotate with the output end of motor 2. The output end of linkage mechanism 4 is used to move along a first direction under the drive of motor 2; and

[0059] The limiting member 6 is connected to the output end of the linkage mechanism 4. The limiting member 6 is provided with a connecting part 63 and a limiting part 61. The connecting part 63 is adapted to the positioning groove 31 and is connected to the push rod 3. The limiting part 61 is placed in the guide groove 14 and can slide with the guide groove 14.

[0060] This utility model discloses an electric nail gun, comprising a base 1, a motor 2, a push rod 3, a linkage mechanism 4, and a limiting member 6. The motor 2 drives the input end of the linkage mechanism 4 to rotate, which in turn moves the output end of the linkage mechanism 4 along a first direction. This movement, in turn, pushes the push rod 3 through the limiting member 6, enabling rapid nail clamping. During the movement of the limiting member 6 by the second end of the linkage mechanism 4, the limiting part 61 cooperates with the guide groove 14 of the base 1 to limit and guide the movement of the limiting member 6, thereby achieving the desired nail clamping. The lever 3 provides movement limit and guidance, making the push rod 3 move more smoothly and stably, ensuring that the push rod 3 will not wobble or rotate, thus improving the stability and service life of the electric nail gun. At the same time, when installing the limiting part 6, the limiting part 6 is positioned by using the connection part 63 to cooperate with the positioning groove 31. Finally, the connection part 63 is fixed together with the push rod 3, which facilitates the quick and stable installation of the limiting part 6 on the push rod 3, thereby improving the connection stability between the limiting part 6 and the push rod 3, and further improving the smoothness and stability of the push rod 3's movement.

[0061] Specifically, motor 2 can be either a brushed motor 2 or a brushless motor 2.

[0062] See also Figures 3-6 In one embodiment, the linkage mechanism 4 includes:

[0063] The first link 41 is connected to the output end of the motor 2; and

[0064] The second link 42 has its first end rotatably connected to the first link 41, and its second end rotatably connected to the limiting member 6. Thus, the motor 2 drives the first link 41 to rotate, which in turn causes the second link 42 to swing, allowing its second end to reciprocate along a first direction. This, in turn, moves the push rod 3 along a set direction, achieving rapid clamping of the nail. Because the rotation of the motor 2's output is converted into linear motion through the linkage of the first and second links 41 and 42, this linear motion is relatively stable and does not cause a decrease in accuracy due to wear on the first and second links 41 and 42.

[0065] See also Figures 13-14 In one embodiment, the first link 41 has a mounting hole 411;

[0066] Electric nail guns also include:

[0067] A coupling 100 is provided in the mounting hole 411 and has a coupling hole 1001, which is adapted to the output end of the motor 2 to connect the first connecting rod 41 and the output end of the motor 2 together. That is, the coupling 100 connects the output end of the motor 2 and the first connecting rod 41 together. The coupling 100 can also separate the output end of the motor 2 from the first connecting rod 41, facilitating disassembly and reassembly of the motor 2's output end and the first connecting rod 41 during later maintenance, thereby reducing maintenance difficulty.

[0068] See also Figure 14 In one embodiment, the first connecting rod 41 is further provided with a positioning part 412, which is disposed on the wall of the mounting hole 411.

[0069] The outer peripheral wall of the coupling 100 has a positioning groove 1002, which is adapted to the positioning part 412. That is, the positioning part 412 is inserted into the positioning groove 1002 to position the coupling 100, restrict the coupling 100 from rotating relative to the first connecting rod 41, and ensure that the output end of the motor 2 can efficiently transmit torque to the first connecting rod 41.

[0070] In one embodiment, there are two positioning parts 412 and two positioning slots 1002. The two positioning parts 412 are respectively inserted into a corresponding positioning slot 1002 to reliably limit the rotation of the coupling 100 relative to the first connecting rod 41.

[0071] In one embodiment, the electric nail gun further includes:

[0072] Bearing sleeve 400, the bearing sleeve 400 is disposed between motor 2 and first connecting rod 41; and

[0073] Bearing 300 is located inside bearing sleeve 400;

[0074] The output end of motor 2 passes through the center hole of bearing 300 and bearing sleeve 400, and the inner ring of bearing 300 can rotate with the output end of motor 2. In this way, bearing 300 can be used to support and limit the output end of motor 2, thereby reducing the sway of the output end of motor 2.

[0075] See also Figure 14 In one embodiment, for ease of installation, the output end of the motor 2 is provided with an output shaft 90, which passes through the center hole of the bearing 300 and the bearing sleeve 400, and is inserted into the coupling hole 1001.

[0076] See also Figure 14 For ease of installation, the electric nail gun also includes:

[0077] The locking fastener 200 is located at the end of the output shaft 90 away from the motor 2, and the locking fastener 200 can abut against the end of the coupling 100 away from the motor 2 to prevent the output shaft 90 from disengaging from the coupling 100.

[0078] Of course, in other embodiments, the linkage mechanism 4 can be a flywheel structure or a structure with a swing arm and a groove.

[0079] See also Figure 2 and Figure 12 In one embodiment, the electric nail gun further includes:

[0080] A transmission mechanism 30, the input end of which is connected to the output end of the motor 2, and the output end of the transmission mechanism 30 can rotate with the input end of the transmission mechanism 30; and

[0081] The reducer 20 is mounted on the base 1. The input end of the reducer 20 is connected to the output end of the transmission mechanism 30, and the input end of the reducer 20 can rotate with the output end of the transmission mechanism 30. The output end of the reducer 20 is connected to the input end of the linkage mechanism 4. The reducer 20 and the motor 2 are arranged side by side in a direction perpendicular to the output end of the motor 2. The input end of the transmission mechanism 30 can rotate with the output end of the motor 2 to transmit the output torque of the motor 2 to the input end of the transmission mechanism 30. The output end of the transmission mechanism 30 can rotate with the input end of the transmission mechanism 30 to transmit the torque output from the input end of the transmission mechanism 30 to the output end of the transmission mechanism 30. The input end of the reducer 20 can rotate with the output end of the transmission mechanism 30 to transmit the torque output by the motor 2 to the reducer 20 through the transmission mechanism 30. Thus, the output end of the reducer 20 drives the linkage mechanism 4 to move. Since the motor 2 and the reducer 20 are arranged side by side in a direction perpendicular to the output end of the motor 2, the space utilization rate of the electric nail gun in the direction perpendicular to the output end of the motor 2 is improved. This ensures that the electric nail gun does not occupy too much space in the direction parallel to the output end of the motor 2, and that the electric nail gun does not occupy too much space in a single direction. This does not obstruct the operator's line of sight during operation, making it more convenient for the operator to operate the electric nail gun.

[0082] In one embodiment, the substrate 1 has a receiving cavity, and the transmission mechanism 30 is disposed in the receiving cavity so that the transmission mechanism 30 is housed in the substrate 1. This not only improves the space utilization of the substrate 1, but also protects the transmission mechanism 30.

[0083] See also Figure 2 and Figure 12 In one embodiment, the electric nail gun further includes:

[0084] Support base 40, support base 40 supports motor 2 and reducer 20; and

[0085] Cover plate 50 is placed on the side of support base 40 away from motor 2 and reducer 20. Cover plate 50 and support base 40 form the aforementioned receiving cavity. During installation, motor 2 and reducer 20 can be installed on support base 40 first, then the input end of transmission mechanism 30 can be connected to the output end of motor 2, then the output end of transmission mechanism 30 can be connected to the input end of reducer 20, and finally cover support base 40 with cover plate 50. This greatly reduces the installation difficulty of motor 2, reducer 20 and transmission mechanism 30, and makes the installation of motor 2, reducer 20 and transmission mechanism 30 more convenient.

[0086] See also Figure 12In one embodiment, the support base 40 is provided with a first positioning part 401 and a second positioning part 402. The first positioning part 401 and the second positioning part 402 are arranged side by side along a direction perpendicular to the output end of the motor 2. The first positioning part 401 is connected to the motor 2 to provide a positioning function for the motor 2, so as to facilitate the quick and accurate installation of the motor 2 on the support base 40. The second positioning part 402 is connected to the reducer 20 to provide a positioning function for the reducer 20, so as to facilitate the quick and accurate installation of the reducer 20 on the support base 40.

[0087] In one embodiment, the first positioning part 401 may have a positioning hole that cooperates with the motor 2, and the second positioning part 402 may have a positioning groove that cooperates with the end of the reducer 20 that is close to the support base 40.

[0088] Of course, in other embodiments, both the first positioning part 401 and the second positioning part 402 may be provided with positioning protrusions, as long as they can achieve the installation and positioning of the motor 2 and the reducer 20.

[0089] See also Figure 12 In one embodiment, the first positioning part 401 is provided with a third connecting hole 4011 and a second fastener 60. The head of the second fastener 60 abuts against the side of the first positioning part 401 near the cover plate 50. The rod of the second fastener 60 passes through the third connecting hole 4011 and is screwed to the motor 2 so as to reliably fix the motor 2 on the first positioning part 401.

[0090] The second positioning part 402 is provided with a fourth connecting hole 4021 and a third fastener 70. The head of the third fastener 70 abuts against the side of the second positioning part 402 near the cover plate 50. The rod of the third fastener 70 passes through the fourth connecting hole 4021 and is screwed to the reducer 20 to reliably fix the reducer 20 on the second positioning part 402.

[0091] To further improve the installation stability of the motor 2, in one embodiment, there are multiple third connecting holes 4011 and multiple fasteners 60. The multiple third connecting holes 4011 are arranged in sequence around the output end of the motor 2, and the second fasteners 60 pass through the corresponding third connecting holes 4011 and are screwed together with the motor 2.

[0092] To further improve the installation stability of the reducer 20, in one embodiment, there are multiple fourth connecting holes 4021 and multiple third fasteners 70. The multiple fourth connecting holes 4021 are arranged sequentially around the input end of the reducer 20, and the third fasteners 70 pass through the corresponding fourth connecting holes 4021 and are screwed together with the reducer 20.

[0093] In one embodiment, the support 40 has a threaded hole;

[0094] The cover plate 50 has a fifth connecting hole 501;

[0095] Matrix 1 also includes:

[0096] The fourth fastener 80 has its head abutting against the side of the cover plate 50 away from the support base 40. The rod of the fourth fastener 80 passes through the fifth connecting hole 501 and is screwed into the threaded hole to reliably fix the cover plate 50 and the support base 40 together. The connection operation is convenient and the connection efficiency is high.

[0097] In one embodiment, there are multiple threaded holes, fifth connecting holes 501 and fourth fasteners 80. The fourth fasteners 80 pass through the corresponding fifth connecting holes 501 and are screwed to the corresponding threaded holes to further improve the connection stability between the cover plate 50 and the support base 40.

[0098] Of course, in other embodiments, the cover plate 50 and the support base 40 can also be connected together by snap-fitting, welding or other means.

[0099] See also Figure 12 In one embodiment, the transmission mechanism 30 includes:

[0100] The drive gear 301 is sleeved on the output end of the motor 2 and can rotate with the output end of the motor 2.

[0101] Driven gear 302 and driving gear 301 are arranged side by side in a direction perpendicular to the output end of motor 2. Driven gear 302 meshes with driving gear 301 and is connected to the input end of reducer 20. That is, transmission mechanism 30 is a gear mechanism. Gear mechanism has the advantages of maintaining accurate transmission ratio, large speed range, high transmission efficiency, long service life, compact structure, small size and reliable operation. It can improve the transmission efficiency of power device while reducing the space occupied, so that the overall structure of power device is more compact and occupies less space.

[0102] See also Figure 12 In one embodiment, the transmission mechanism 30 further includes:

[0103] An intermediate gear 303 is rotatably mounted on the support base 40 and is located between the driving gear 301 and the driven gear 302. The driving gear 301 meshes with the driven gear 302 through the intermediate gear 303. Since the driving gear 301 meshes with the driven gear 302 through the intermediate gear 303, the power of the driving gear 301 can be transmitted to the driven gear 302 using the intermediate gear 303. At the same time, since the intermediate gear 303 is rotatably mounted on the support base 40, it can support the driving gear 301 and the driven gear 302, thereby improving the assembly stability of the driving gear 301 and the driven gear 302, which is conducive to further improving the transmission efficiency of the transmission mechanism 30.

[0104] Of course, in other embodiments, the transmission mechanism 30 may also adopt a chain drive mechanism 30, belt drive mechanism 30 or other transmission structures.

[0105] See also Figure 3 and Figure 8 In one embodiment, the limiting member 6 is further provided with a trigger part 62;

[0106] The base 1 is equipped with a first sensor 7 and a second sensor 8. When the push rod 3 moves outward relative to the base 1 to a set position, the contact of the first sensor 7 cooperates with the trigger part 62 to trigger the first sensor 7, thereby stopping the motor 2. When the push rod 3 moves inward relative to the base 1 to a set position, the contact of the second sensor 8 cooperates with the trigger part 62 to trigger the second sensor 8, thereby stopping the motor 2. This limits the inward movement of the push rod 3 relative to the base 1, thus limiting the travel of the push rod 3. When the push rod 3 moves to the set position, the trigger part 62 cooperates with the contact of the corresponding sensor to trigger the corresponding sensor, thereby causing the controller of the electric nail gun to control the motor 2 to automatically stop based on the feedback information from the sensor, thereby achieving accurate positioning of the push rod 3.

[0107] Both the first sensor 7 and the second sensor 8 can be contact sensors or non-contact sensors.

[0108] Of course, in other implementations, the electric nail gun may be equipped with only one sensor. In this case, the motor can be shut down by calculating the distance or time away from the sensor.

[0109] See also Figure 8In one embodiment, the connecting part 63 extends along the first direction, the limiting part 61 and the triggering part 62 are respectively placed on opposite sides of the connecting part 63, and the connecting part 63, the limiting part 61 and the triggering part 62 form a cross-shaped structure, so that the limiting member 6 is formed into a cross-shaped structure, and the middle part of the limiting member 6 is connected to the output end of the linkage mechanism 4, so as to improve the connection stability between the limiting member 6 and the linkage mechanism 4, thereby improving the smoothness and stability of the push rod 3 movement.

[0111] Main body 11, which supports motor 2 and push rod 3;

[0112] A first connecting plate 12 is separately disposed from the main body 11, and the first connecting plate 12 is disposed on the main body 11; and

[0113] The second connecting plate 13 is separately set from the first connecting plate 12, and the second connecting plate 13 and the first connecting plate 12 form a guide groove 14.

[0114] See also Figure 9 and Figure 10 In one embodiment, the first connecting plate 12 is provided with a top plate portion 121 and a side plate portion 122. The top plate portion 121 is connected to the main body 11 and has a positioning hole 1211. The side plate portion 122 is provided on one side of the top plate portion 121 along the moving direction perpendicular to the push rod 3. Both the top plate portion 121 and the side plate portion 122 have a first connecting hole.

[0115] The second connecting plate 13 and the side plate portion 122 form a guide groove 14. The second connecting plate 13 is provided with a positioning protrusion 131, which is adapted to a positioning hole 1211. The positioning protrusion 131 has a second connecting hole, which is connected to the first connecting hole by a first fastener to fix the second connecting plate 13 and the first connecting plate 12 together. In this way, the positioning protrusion 131 and the positioning hole 1211 can be used to install and position the second connecting plate 13, which facilitates the quick and correct installation of the second connecting plate 13 onto the first connecting plate 12, greatly improving installation efficiency. At the same time, the first connecting plate 12 and the second connecting plate 13 can be reliably fixed together by connecting the first connecting hole and the second connecting hole with the first fastener, resulting in high connection stability.

[0117] The elastic element 9 has one end abutting against the base 1 and the other end abutting against the push rod 3. The elastic element 9 provides a driving force for the push rod 3 to move inward relative to the base 1. See also... Figure 4 When the push rod 3 is driven by the linkage mechanism 4 to move inward relative to the base 1 to the set position, the included angle between the first link 41 and the second link 42 in the linkage mechanism 4 is the smallest. The lateral force generated by the linkage of the first link 41 and the second link 42 on the push rod 3 is greater than the axial force. Since the elastic element 9 can provide the push rod 3 with the driving force to move inward relative to the base 1, it plays the role of increasing the axial force when the push rod 3 moves inward. It cooperates with the guide groove 14 to make the push rod 3 move inward more smoothly.

[0118] See also Figure 3 In one embodiment, the elastic element 9 is sleeved on the outer peripheral wall of the push rod 3, and the push rod 3 guides the elastic element 9 so that the elastic element 9 can extend and retract more smoothly.

[0119] In one embodiment, the elastic element 9 can be a spring, or an elastic structure such as a sheet, elastic rubber element, or bellows, as long as it can provide the push rod 3 with a driving force to move inward relative to the base 1.

[0120] In one embodiment, the base 1 has a guide hole, through which the push rod 3 is movably inserted to guide its movement, making the push rod 3 move more smoothly and stably.

[0121] See also Figure 2 In one embodiment, the electric nail gun further includes:

[0122] The anti-wear sleeve 10 is provided on the base 1. The anti-wear sleeve 10 has a guide hole. By providing a guide hole on the anti-wear sleeve 10, wear can be reduced, thereby effectively avoiding the problem of decreased accuracy caused by the movement and wear of the push rod 3, and enabling the push rod 3 to move more smoothly and for longer.

[0123] In one embodiment, there are two anti-wear sleeves 10, which are spaced apart along the moving direction of the push rod 3.

[0124] In one embodiment, the anti-wear sleeve 10 is made of copper to give it better anti-wear performance, which can greatly improve its service life and reduce maintenance costs.

[0125] Of course, in other embodiments, the anti-wear sleeve 10 may also be a structure made of other materials with wear-resistant properties, such as stainless steel.
