[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] like Figures 1 to 3 As shown, the embodiment of the utility model provides a rivet device for processing wood furniture, including a machine base 1, a vibrating feed plate 2, an intermittent feed track 3, a clamping nail assembly 4, a rivet punching mechanism 5 and a positioning table 6;

[0041] The rivet punching mechanism 5 is arranged on the top of the machine base 1, the positioning platform 6 is arranged on the bottom of the machine base 1, and the clamping nail assembly 4 is located between the rivet punching mechanism 5 and the positioning platform 6;

[0042] The positioning platform 6 is used to position the riveting holes of the wood workpiece;

[0043] The discharge end of the vibrating feeding tray 2 is connected to the feed end of the intermittent feeding track 3, and the discharge end of the intermittent feeding track 3 is located in the clamping nail assembly 4;

[0044] The vibrating feed plate 2 can transport the rivets to the intermittent feeding track 3 through vibration. The intermittent feeding track 3 can intermittently slide the rivets into the clamping assembly 4. The clamping assembly 4 can clamp the rivets. When the user places the riveting holes of the wooden workpiece on the positioning table 6, the rivet stamping mechanism 5 can push and stamp the rivets in the clamping assembly 4 into the riveting holes of the wooden workpiece to complete the riveting.

[0045] The clamp assembly 4 includes a rivet clamp seat 41, a connecting arm 42 and a lifting cylinder 43;

[0046] The rivet clamp seat 41 is used to position and place rivets, the lifting cylinder 43 is arranged on the machine base 1, and the movable end of the lifting cylinder 43 is connected to the rivet clamp seat 41 through the connecting arm 42;

[0047] The lifting cylinder 43 is used to drive the rivet clamp seat 41 to move up and down, so as to adjust the position of the rivet clamp seat 41 between the positioning platform 6 and the rivet punching mechanism 5 .

[0048] The rivet clamp seat 41 is provided with a guide through hole 410 for clamping the rivet, and the side wall of the rivet clamp seat 41 is provided with a slide groove 411 connected to the guide through hole 410, and the slide groove 411 is used for the rivet on the intermittent feeding track 3 to slide into the guide through hole 410.

[0049] like Figure 3 As shown, further, the rivet clamp seat 41 is a detachable structure, and the rivet clamp seat 41 includes a left half clamp seat 412, a right half clamp seat 413 and a locking screw 414; the left half clamp seat 412 and the right half clamp seat 413 are connected by the locking screw 414, and the locking screw 414 is used to adjust the distance between the left half clamp seat 412 and the right half clamp seat 413; the user can change the distance between the left half clamp seat 412 and the right half clamp seat 413 by adjusting the locking screw 414 to match the corresponding rivet size, thereby avoiding the situation where the clamp assembly 4 cannot adapt to the clamping when the user needs to rivet other types of rivets.

[0050] like Figure 1As shown, further, the positioning platform 6 is provided with a pressure column 61 for carrying the wooden workpiece; the pressure column 61 is provided with a guide column 62 for guiding and positioning with the riveting hole of the wooden workpiece; the diameter of the pressure column 61 is larger than the diameter of the guide column 62. The pressure column 61 is used to carry the wooden workpiece to provide stable support and pressure during the riveting process; the guide column 62 has a smaller diameter, which matches the riveting hole of the wooden workpiece, and can provide a guiding effect to prevent the rivet from deviating from the target position or tilting.

[0051] like Figure 2 As shown, further, the intermittent feeding track 3 includes a track body 31 and a blocking mechanism 32; the track body 31 is provided with a feeding slide 310 for positioning and conveying rivets; the blocking mechanism 32 is transversely arranged on the feeding slide 310, and the blocking mechanism 32 is used to block or release the rivets on the feeding slide 310 from entering the chute 411. The blocking mechanism 32 can block or release the rivets on the track body 31, thereby realizing intermittent conveying of the rivets, and preventing the rivets from being continuously conveyed and stuck in the clamping nail assembly 4, causing riveting failure.

[0052] like Figure 2 As shown, further, the material blocking mechanism 32 includes a push-pull cylinder (not shown), a push-pull slider 321, a first baffle 322 and a second baffle 323; a push-pull groove 311 is provided on the back of the track body 31, and the push-pull slider 321 can slide along the push-pull groove 311, and the movable end of the push-pull cylinder is connected to the end of the push-pull slider 321; the first baffle 322 and the second baffle 323 are respectively located on both sides of the push-pull slider 321, and the first baffle 322 and the second baffle 323 are provided with mutually parallel inclined portions 3220 near the side walls of the feeding chute 310; a gap is formed between the two inclined portions 3220 for the rivets on the feeding chute 310 to slide into. When the rivet enters the feed chute 310 and slides downward, it moves to the inclined surface 3220 of the first baffle 322 and the second baffle 323. The angle and position of the inclined surface block the rivet during the sliding process and prevent it from continuing to move downward into the slide groove 411. When the rivet needs to be released, the push-pull cylinder is activated, and the push-pull slider 321 slides horizontally, causing the first baffle 322 and the second baffle 323 to move at the same time, thereby pushing the rivet to slide along the inclined surface 3220 to be released.

[0053] Furthermore, a vertical surface 3221 extending downward is provided at the lower end of the inclined surface 3220 of the first baffle 322 or the second baffle 323. The vertical surface 3221 can guide the rivet. When the push-pull slider 321 moves laterally to release the rivet, the rivet will slide over the vertical surface 3221. The vertical surface 3221 can help the rivet maintain the correct direction and position, ensuring that the rivet can slide smoothly in the feeding chute 310.

[0054] Furthermore, the track body 31 includes a vertical section 312 and a bent section 313 connected to the vertical section 312. The feed section of the vertical section 312 is connected to the discharge end of the vibrating feed tray 2, and the discharge end of the bent section 313 is located at the side end of the chute 411. The vertical section 312 is used to transport the rivet from the discharge end of the vibrating feed tray 2 to the bent section 313 to adjust the direction. By connecting the vertical section 312 and the bent section 313, the rivet can be guided to the correct transport direction so that it enters the clamping nail assembly 4 for clamping.

[0055] like Figure 1 As shown, further, a guide groove structure 415 is provided at the top of the guide through hole 410. When the rivet is pushed into the riveting hole of the wood workpiece, the guide groove structure 415 can provide a guide channel to ensure that the rivet punching mechanism 5 can accurately pass through the guide through hole 410 and push the rivet into the riveting hole to avoid deflection or misalignment.

[0056] like Figure 1 As shown, further, the rivet punching mechanism 5 includes a lifting drive device 51 and a punching head 52. The movable end of the lifting drive device 51 is connected to the punching head 52 to drive the punching head 52 to apply punching force to the rivet on the rivet clamp 41. The lifting drive device 51 can control the punching head 52 to move up and down. It should be noted that the power source of the lifting drive device 51 can be a hydraulic or pneumatic system, or an electric drive system. By manipulating the lifting drive device 51, the punching head 52 can be moved in the vertical direction, thereby applying punching force to the rivet. In this embodiment, the lifting drive device 51 is a hydraulic cylinder.

[0057] The vibrating feeding plate 2 of the utility model can convey the rivets into the intermittent feeding track 3 through vibration, and the intermittent feeding track 3 can intermittently slide the rivets into the clamping nail assembly 4, and the clamping nail assembly 4 can clamp the rivets. When the user places the riveting hole of the wooden workpiece on the positioning table 6, the rivet punching mechanism 5 can push and punch the rivet in the clamping nail assembly 4 into the riveting hole of the wooden workpiece to complete the riveting; the rivet clamping seat 41 of the clamping nail assembly 4 is a detachable structure, and the user can change the distance between the left half clamping seat 412 and the right half clamping seat 413 by adjusting the locking screw 414 to match it with the corresponding rivet size, avoiding the situation that the clamping nail assembly 4 cannot adapt to the clamping when the user needs to rivet other types of rivets; in addition, a material blocking mechanism 32 is provided on the track body 31, and the material blocking mechanism 32 can block or release the rivets on the track body 31, thereby realizing intermittent conveying of the rivets, avoiding the continuous conveying of the rivets and getting stuck in the clamping nail assembly 4 to cause riveting failure.

[0058] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
