Description

Technical Field

[0001] This invention relates to the field of furniture processing technology, and in particular to a high-synchronization row nailing device. Background Technology

[0002] In the current processing of wooden furniture, the main methods used are mortise and tenon joints, tongue and groove joints, nail fixing, or glue bonding. Mortise and tenon joints and tongue and groove joints require chiseling and cutting the wood, which not only has requirements on the thickness and size of the wood but also has low processing efficiency, depends on worker skill, and is not conducive to mass production. While glue bonding is simple and quick, its curing effect is poor in low-temperature or high-humidity environments, and the presence of formaldehyde in glue may affect consumer choices in the current market.

[0003] Steel nail fixing is widely used in mass furniture production due to its simple and convenient installation method. Currently, steel nail fixing typically requires workers to use a pneumatic nail gun to drive nails into multiple locations, and the fixing points rely on manual alignment, which is prone to errors. Furthermore, driving nails into multiple locations is time-consuming and has low processing efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a row-mounted nailing device with high synchronization, which solves the problem that workers need to nail and fix the furniture at different points in the existing furniture processing process, resulting in deviations in the processing points and low processing efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a high-synchronization row nailing device, comprising:

[0006] The connecting mechanism includes a motherboard, a support component, a positioning and fixing component, and a clamping component. A connection slot extends from the top of the motherboard to its interior. The support component has a mounting part on the side near the motherboard, which is inserted into the connection slot. The clamping component is located on the side of the support component away from the motherboard. The positioning and fixing component is embedded in the mounting part. When fixed, the positioning and fixing component extends from the side wall of the mounting part and abuts against the inner surface of the connection slot, thereby fixing the support component to the motherboard.

[0007] The pneumatic nail gun is mounted on the support assembly and held by the corresponding clamping assembly.

[0008] The synchronous triggering mechanism is located on the side of the main board away from the supporting component. It triggers the pushing component located on the clamping component to act simultaneously through the air circuit, thereby enabling the nail gun to nail synchronously.

[0009] In one embodiment, the mounting part is generally L-shaped, and a fixed cavity is provided inside the mounting part. The positioning and fixing component includes an actuating part and an abutting part. The abutting part is disposed in the fixed cavity. The actuating part extends into the fixed cavity from the top of the mounting part and is driven to connect with the mounting part. An actuating through hole is provided on the side wall of the fixed cavity. In use, the actuating part causes the abutting part to extend out of the fixed cavity from the actuating through hole and abut against the inside of the connecting slot.

[0010] In one embodiment, the abutting part includes two movable push plates and a telescopic connecting rod and an abutting protrusion corresponding to the movable push plates. The two ends of the telescopic connecting rod are respectively disposed on the inner walls of the movable push plates and the fixed cavity. The abutting protrusion is disposed corresponding to the action through hole and is located on the side of the movable push plate close to the action through hole.

[0011] In one embodiment, the actuating part is located in the center of two movable push plates, the distance between the movable push plates gradually decreases from top to bottom, and the maximum distance between the movable push plates is greater than the diameter of the actuating part.

[0012] In one embodiment, the support assembly includes a fixed plate and a support plate. The mounting part is disposed on the side of the fixed plate close to the main board, and the support plate is disposed on the side of the fixed plate away from the main board and located at the bottom of the fixed plate. A buffer plate is provided on the support plate, and a buffer spring is provided between the buffer plate and the support plate. The clamping assembly is disposed above the support plate and is rotatably connected to the fixed plate. The buffer plate is connected to the clamping assembly through a trigger link, so that after the buffer plate is compressed and displaced, it drives the trigger link to trigger the clamping assembly to clamp.

[0013] In one embodiment, the clamping assembly includes two clamping arc plates, a push rod, and a fixing ring. One side of the clamping arc plate is hinged to the fixing plate, and both ends of the push rod are respectively hinged to the clamping arc plate and the fixing plate. The fixing ring is located at the bottom of the outer surface of the clamping arc plate. One end of the triggering rod is connected to the buffer plate, and the other end of the triggering rod extends into the fixing ring. When the pneumatic nail gun is placed, the triggering rod is driven downward by the buffer plate until it is dislodged from the fixing ring, causing the push rod to push the clamping arc plate to rotate and thus clamp the pneumatic nail gun.

[0014] In one embodiment, the clamping arc plate has an avoidance opening corresponding to the pneumatic nail gun, and the inside of the clamping arc plate is provided with a sponge filling layer.

[0015] In one embodiment, the synchronous triggering mechanism includes a master control valve, a connecting pipe, and a pushing component. The master control valve is located on the side of the main board away from the supporting components, and each supporting component is provided with a corresponding pushing component. An airflow channel is provided in the fixed plate, and the connecting pipe is embedded between the fixed plates and communicates with the airflow channel. The airflow channel communicates with the pushing component, thereby connecting the master control valve with the pushing component.

[0016] In one embodiment, a press valve is provided between the airflow channel and the push assembly, and a control cavity is provided in the fixed plate. The press valve is located in the control cavity. An L-link is used in the control cavity. The middle part of the L-link is hinged in the control cavity. The two ends of the L-link abut against the actuating part and the press valve, respectively. After the actuating part is activated, the L-link rotates, thereby causing the press valve to be pressed open.

[0017] In one embodiment, the pushing component includes a pushing cylinder, a bellows, and a trigger push plate; the pushing cylinder is disposed on the outer surface of the clamping component, the trigger push plate is disposed at the output end of the pushing cylinder, and the pushing cylinder is connected to the pressing valve through the bellows.

[0018] The beneficial effects of this invention are as follows:

[0019] Currently, furniture manufacturing requires operators to use pneumatic nail guns to nail nails at different points for fixation. This significantly impacts processing efficiency during mass production. Furthermore, manual operation can introduce errors, potentially causing variations in the spacing between different points and resulting in poorer fixation.

[0020] Therefore, the present invention fixes multiple pneumatic nail guns through a connecting mechanism and enables operators to operate the pneumatic nail guns simultaneously for nailing operations through a synchronous triggering mechanism. While ensuring efficiency, it can avoid vibration and displacement of the board caused by different pneumatic nail guns nailing in sequence, thus ensuring the accuracy and effect of nailing and fixing.

[0021] Furthermore, simply fixing the pneumatic nail gun requires removing or re-fixing it when processing furniture of different sizes, making it impossible to adjust the nailing position as needed. Therefore, this invention incorporates a positioning and fixing component in the mounting section of the support assembly. This allows the support assembly to adjust its position relative to the main board. After adjustment, the positioning and fixing component in the mounting section abuts against the connecting slot to achieve a fixed and limited position. This provides the support assembly with flexible adjustment space while ensuring a secure fixation, preventing misalignment of different support components during nailing and ensuring the accuracy and safety of nailing.

[0022] Other features and beneficial effects of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects of the invention and other beneficial effects may be realized and obtained by means of the structures and / or components pointed out in the description and claims.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. The technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, it should be noted that all terms used in this invention (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains, and should not be construed as limiting the invention; it should be further understood that the terms used in this invention should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this invention.

[0034] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please refer to Figures 1 to 7 A high-synchronization row nailing device, comprising:

[0036] The connecting mechanism 1 includes a motherboard 11, a supporting component 12, a positioning and fixing component 13, and a clamping component 14. A connecting slot 111 extends from the top of the motherboard 11 to its interior. The supporting component 12 has a mounting part 121 on the side near the motherboard 11, which is inserted into the connecting slot 111. The clamping component 14 is located on the side of the supporting component 12 away from the motherboard 11. The positioning and fixing component 13 is embedded in the mounting part 121. When fixed, the positioning and fixing component 13 extends from the side wall of the mounting part 121 and abuts against the inner surface of the connecting slot 111, thereby fixing the supporting component 12 to the motherboard 11.

[0037] The pneumatic nail gun 2 is mounted on the support assembly 12 and is held by the corresponding clamping assembly 14.

[0038] The synchronous triggering mechanism 3 is located on the side of the main board 11 away from the supporting component 12. It triggers the pushing component 31 located on the clamping component 14 to act simultaneously through the air circuit, thereby enabling the nail gun to nail synchronously.

[0039] Specifically, the thickness of the mounting part 121 is less than or equal to the thickness of the connecting slot 111.

[0040] Since the mounting part 121 needs to be inserted entirely into the connecting slot 111, the thickness of the mounting part 121 cannot be greater than the thickness of the insertion slot. Therefore, the friction between the mounting part 121 and the connecting slot 111 cannot be too large, and the overall fixation of the device needs to be achieved by the positioning and fixing component 13. In this embodiment, the mounting part 121 is generally L-shaped, and a fixing cavity 1211 is provided inside the mounting part 121. The positioning and fixing component 13 includes an actuating part 131 and an abutting part 132. The abutting part 132 is disposed in the fixing cavity 1211. The actuating part 131 extends from the top of the mounting part 121 into the fixing cavity 1211 and is driven to connect with the mounting part 121. An actuating through hole 1212 is provided on the side wall of the fixing cavity 1211. In use, the actuating part 131 causes the abutting part 132 to extend out of the fixing cavity 1211 through the actuating through hole 1212 and abut against the inside of the connecting slot 111.

[0041] Specifically, the actuating part 131 can be a connecting bolt, and the mounting part 121 has a threaded hole corresponding to the connecting bolt. Preferably, the threaded hole has a thread on the side closest to the threaded hole, and the connecting bolt has a thread in the middle. When the connecting bolt is not triggered, the lower end of the thread of the connecting bolt abuts against the upper end of the thread of the threaded hole. This arrangement ensures that the connecting bolt does not loosen during operation, and that the whole assembly is not under stress when not in operation. It also prevents the connecting bolt from scratching the abutting part 132, thereby improving the service life of the positioning and fixing assembly 13.

[0042] To ensure that the abutment part 132 can fully contact the connecting slot 111 under the action of the actuating part 131, the abutment part 132 includes two movable push plates 1321 and telescopic connecting rods 1322 and abutment protrusions 1323 corresponding to the movable push plates 1321. The two ends of the telescopic connecting rods 1322 are respectively set on the inner walls of the movable push plates 1321 and the fixed cavity 1211. The abutment protrusions 1323 are set corresponding to the action through hole 1212 and are located on the side of the movable push plate 1321 near the action through hole 1212. Preferably, telescopic connecting rods 1322 are provided on both the upper and lower sides of the movable push plate 1321. This arrangement allows the movable push plate 1321 to tilt first and then move as a whole as the actuating part 131 tightens. In the tilted state, the abutment protrusions 1323 extend out of the fixed cavity 1211, providing some friction, which facilitates further tightening by the operator and improves the ease of fixing.

[0043] Specifically, the telescopic link 1322 has a spring inside. After the actuating part 131 is rotated out, the telescopic link 1322 resets the movable push plate 1321, thereby separating the abutting protrusion 1323 from the connecting slot 111.

[0044] Preferably, the surface of the abutment protrusion 1323 is provided with a rubber layer. This design increases friction while giving the abutment part 132 a certain buffering capacity, providing cushioning and vibration reduction when multiple pneumatic nail guns 2 are firing nails simultaneously, preventing excessive reaction force from causing the operator to lose control, thereby improving safety.

[0045] In order to ensure that the actuating part 131 can smoothly push the movable push plate 1321 and avoid the actuating part 131 from hitting the top of the movable push plate 1321 and getting stuck, in this embodiment, the actuating part 131 is located in the center of the two movable push plates 1321, the distance between the movable push plates 1321 gradually decreases from top to bottom, and the maximum distance between the movable push plates 1321 is greater than the diameter of the actuating part 131.

[0046] Preferably, the movable push plate 1321 has sliders at both ends, and the inner wall of the fixed cavity 1211 has a slide rail. The sliders slide back and forth in the slide rail, thereby ensuring that the position of the movable push plate 1321 does not shift during long-term use, and ensuring the stability and accuracy of the positioning and fixing component 13.

[0047] The support component 12 is used to place the pneumatic nail gun 2. However, the height of the pneumatic nail gun 2 varies depending on the specifications, resulting in different trigger positions. If the pneumatic nail gun 2 is placed directly on the support component 12, it is easy to cause the synchronous triggering component to be difficult to align, and the clamping component 14 to clamp the connection between the handle and the magazine of the pneumatic nail gun 2, causing the clamping component 14 to fail to close, thus leading to clamping failure. Therefore, in this embodiment, the supporting assembly 12 includes a fixed plate 122 and a supporting plate 123. The mounting part 121 is disposed on the side of the fixed plate 122 close to the main board 11, and the supporting plate 123 is disposed on the side of the fixed plate 122 away from the main board 11 and located at the bottom of the fixed plate 122. A buffer plate 124 is provided on the supporting plate 123, and a buffer spring 125 is provided between the buffer plate 124 and the supporting plate 123. The clamping assembly 14 is disposed above the supporting plate 123 and is rotatably connected to the fixed plate 122. The buffer plate 124 is connected to the clamping assembly 14 through a trigger link 146, so that after the buffer plate 124 is displaced by pressure, it drives the trigger link 146 to trigger the clamping of the clamping assembly 14. When different sizes of pneumatic nail guns 2 are placed on the buffer plate 124, their different weights cause the buffer plate 124 to undergo varying degrees of pressure displacement. This changes the distance between the pushing component 31 and the buffer plate 124, allowing the pushing component 31 to adapt to different sizes of pneumatic nail guns 2 and improving the adaptability of the device. Specifically, those skilled in the art can select a suitable buffer spring 125 according to the type of pneumatic nail gun 2 actually used, without making specific limitations.

[0048] In this embodiment, the clamping assembly 14 includes two clamping arc plates 141, a pushing rod 142, and a fixing ring 143. One side of the clamping arc plate 141 is hinged to the fixing plate 122, and both ends of the pushing rod 142 are respectively hinged to the clamping arc plate 141 and the fixing plate 122. The fixing ring 143 is located at the bottom of the outer surface of the clamping arc plate 141. One end of the trigger rod 146 is connected to the buffer plate 124, and the other end of the trigger rod 146 extends into the fixing ring 143. When the pneumatic nail gun 2 is placed, the trigger rod 146 is driven by the buffer plate 124 to move downward until it is dislodged from the fixing ring 143, so that the pushing rod 142 pushes the clamping arc plate 141 to rotate and thus clamp the pneumatic nail gun 2. Specifically, the push rod 142 causes the two clamping arc plates 141 to rotate towards the center of the fixed plate 122. When not clamping, the clamping arc plates 141 remain in an unfolded state due to the fixed limit of the fixed ring 143 and the trigger rod 146, making it convenient for the operator to place the pneumatic nail gun 2 onto the buffer plate 124. After the pneumatic nail gun 2 is placed, the buffer plate 124 descends, causing the trigger rod 146 to disengage from the fixed ring 143. The push rod 142 then pushes the clamping arc plates 141 to rotate, thereby clamping the pneumatic nail gun 2 and completing the fixation. When removing the pneumatic nail gun 2, the operator needs to manually pry open the clamping arc plates 141 and lift the pneumatic nail gun 2, allowing the trigger rod 146 to extend into the fixed ring 143 and complete the limiting of the clamping arc plates 141.

[0049] Preferably, the clamping arc plate 141 has an clearance opening 144 corresponding to the pneumatic nail gun 2, and the clamping arc plate 141 has a sponge filling layer 145 inside. The sponge filling layer 145 restricts the movement of the pneumatic nail gun 2 after it is clamped, thereby ensuring that the pushing component 31 can be aligned with the pneumatic nail gun 2 and ensuring the accuracy of the triggering action. Specifically, the clearance opening 144 is located in the upper middle part of the clamping arc plate 141 to avoid the connecting part of the pneumatic nail gun 2, thereby ensuring that the clamping arc plate 141 can be clamped in place. Furthermore, after the pneumatic nail gun 2 performs nailing, the sponge filling layer 145 can effectively absorb the reaction force generated by nailing, preventing the pneumatic nail gun 2 from shifting and ensuring the stability of continuous operation.

[0050] In this embodiment, the synchronous triggering mechanism 3 includes a master control valve 32, a connecting pipe 33, and a pushing component 31. The master control valve 32 is located on the side of the main board 11 away from the supporting component 12, and each supporting component 12 is provided with a corresponding pushing component 31. An airflow channel 1221 is provided in the fixed plate 122, and the connecting pipe 33 is embedded between the fixed plates 122 and communicates with the airflow channel 1221. The airflow channel 1221 communicates with the pushing component 31, thereby connecting the master control valve 32 with the pushing component 31.

[0051] Because the device requires multiple pneumatic nail guns 2, during the fixing process, the operator needs to hold the main board 11 with one hand and place the pneumatic nail gun 2 with the other. During individual operation, misoperation may cause the synchronous triggering component to activate, leading to a safety issue when the pneumatic nail gun 2 fires. Therefore, a pressing valve 34 is provided between the airflow channel 1221 and the pushing component 31. A control cavity is provided within the fixing plate 122, and the pressing valve 34 is located within the control cavity. An L-shaped connecting rod 35 is used within the control cavity, with its middle section hinged within the cavity. Both ends of the L-shaped connecting rod 35 abut against the actuating part 131 and the pressing valve 34, respectively. After the actuating part 131 is activated, the L-shaped connecting rod 35 rotates, thereby pressurizing and opening the pressing valve 34. This design ensures that the operator can only connect the airflow after fixing the pneumatic nail gun 2 and the supporting component 12, effectively improving safety while maintaining operational efficiency.

[0052] Preferably, an adjusting spring is provided between the actuating part 131 and the mounting part 121. After the adjusting spring is set, the actuating part 131 moves away from the mounting part 121 when it does not drive the abutting part 132, thereby ensuring that the L-link 35 does not squeeze the pressing valve 34, thus ensuring safety.

[0053] In this embodiment, the pushing component 31 includes a pushing cylinder 311, a bellows 312, and a trigger push plate 313; the pushing cylinder 311 is disposed on the outer surface of the clamping component 14, the trigger push plate 313 is disposed at the output end of the pushing cylinder 311, and the pushing cylinder 311 is connected to the pressing valve 34 through the bellows 312.

[0054] Preferably, the motherboard 11 has a grip handle 15 on the side away from the support component 12.

[0055] Preferably, the two ends of the main board 11 are provided with fitting grooves 17 and T-shaped sliders 16. This arrangement allows multiple main boards 11 to be combined, thereby increasing the number of air nail guns 2 that can be set and further improving the overall adaptability.
